- Abstract
Background and objective Anemia is a common hematological disorder during pregnancy, with iron deficiency (ID) being the most prevalent cause globally. It severely affects maternal and fetal health. This study aimed to investigate the prevalence of anemia and its association with iron and vitamin B12 deficiency during pregnancy. Materials and methods The study sample consisted of pregnant women attending the 3
rd Clinic of Obstetrics and Gynecology, University General Hospital "Attikon", Athens, Greece, with a total of 145 women eventually analyzed. Blood samples were collected from pregnant women during the first, second, and third trimesters; hematological indices, including hemoglobin (HGB), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red blood cell distribution width (RDW), ferritin, and vitamin B12, were recorded. Iron deficiency anemia was defined as HGB <11.0 g/dl in the first trimester and <10.5 g/dl in the second and third trimesters. Results Iron deficiency anemia is elevated in the course of pregnancy. A significant proportion of pregnant women had vitamin B12 deficiency during pregnancy, with the prevalence increasing from the first to the third trimester. The study also found that iron supplementation improved hematological indices; especially, pregnant women receiving divalent iron had significantly higher levels of HCT, HGB, and ferritin compared to those receiving trivalent iron. Conclusions Screening for iron deficiency anemia should be performed in all pregnant women, and appropriate oral iron therapy should be given as first-line treatment. Early recognition and management of low maternal iron levels are crucial and lead to improved maternal, fetal, and neonatal outcomes. Furthermore, unified international thresholds for ID are required for accurate assessments and appropriate iron supplementing. This study also recommends the screening of vitamin B12 levels as part of the systematic follow-up of pregnant women to identify potential deficiencies and provide appropriate supplementation. Further in-depth studies, particularly related to vitamin B12, are required to provide definitive conclusions and guidance., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

- Abstract
Background: Gastric cancer (GC) is one of the most common and aggressive types of cancer. Immune checkpoint inhibitors (ICIs) have proven effective in treating various types of cancer. The use of ICIs in GC patients is currently an area of ongoing research. The tumor microenvironment (TME) also seems to play a crucial role in cancer progression. Tumor-associated macrophages (TAMs) are the most abundant population in the TME. TAMs are capable of displaying programmed cell death protein 1 (PD-1) on their surface and can form a ligand with programmed death ligand 1 (PD-L1), which is found on the surface of cancer cells. Therefore, it is expected that TAMs may significantly influence the immune response related to immune checkpoint inhibitors (ICIs)., Aim of the Study: Understanding the role of TAMs and PD-1/PD-L1 networking in GC., Methods: A systematic review of published data was performed using MEDLINE (PubMed), Embase, and Cochrane databases. We retrieved articles investigating the co-existence of TAMs and PD-1 in GC and the prognosis of patients expressing high levels of PD-1+ TAMs., Results: Ten articles with a total of 2277 patients were included in the systematic review. The examined data suggest that the expression of PD-L1 has a positive correlation with the infiltration of TAMs and that patients who express high levels of PD-1+ TAMs may have a worse prognosis than those who express low levels of PD-1+ TAMs., Conclusions: TAMs play a pivotal role in the regulation of PD-1/PD-L1 networking and the progression of GC cells. Nevertheless, additional studies are needed to better define the role of TAMs and PD-1/PD-L1 networking in GC.

- Abstract
Background: Intermittent fasting (IF) diets have been popular since the last few decades because of their provable clinical efficiency on weight control of the subjects. These diet types are generally safe, resulting in health promoting effects against several human diseases like cardiovascular diseases, diabetes mellitus, neurogenerative disorders and cancer., Objective: To review whether IF can act against cancer development and progression, highlighting potential anticancer molecular mechanisms in clinical studies., Methods: Applied summarization of the available clinical studies investigating the effectiveness of IF against cancer development and progression and cancer-induced indicators. Scientific databases, e.g. , PubMed, and Scopus, were comprehensively searched using relative words to identify in vivo and in vitro data, as well as clinical studies., Results: IF seems to exert health-promoting effects in cancer patients through induction of autophagy, which enhances the in vivo suppression of tumor development, by chemotherapy. IF provokes tumors to chemotherapy and defends the normal cells from its adverse side effects, increasing the immune response. In addition, it enhances the cytotoxic CD8(+) tumor-infiltrating lymphocytes and the bone marrow lymphoid progenitor cells, delaying the cancer progression. IF reduces oxidative stress via repression of translation and induces cellular apoptosis. Fasting exerts anti-aging properties modulating the secretion of IGF-1, IGFBP-1, glucose, and insulin while, at the same time, it integrates cell adaptive responses and activates cell signaling pathways which stimulates antioxidant defenses, DNA repairment, control of protein quality, mitochondrial synthesis while decreasing inflammation., Conclusion: IF appears to exert health promoting effects against cancer development and progression, suppressing several kinds of cancer. There are well-recognized and not well-recognized molecular processes accentuating its anticancer outcomes; however, well-designed clinical trials and further molecular studies are strongly recommended., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Introduction: Women undergoing mastectomy choose to pursue breast reconstruction (BR) in order to reduce their body image distress.Adjuvant chest wall irradiation is associated with a negative cosmetic outcome. The aim of our review was to identify the optimal timing of BR relating to radiotherapy delivery., Materials and Methods: Using Cochrane Library, Embase, PubMed, Springer, Wanfang and CNKI, we performed a non-systematic review of articles published up to August 2021., Results: There is no hard evidence in favor of immediate, delayed or 2-stage BR when post-mastectomy radiation is indicated. Immediate and 2-stage BR seem to be valid alternatives to delayed BR., Conclusions: Further research is essential in order to assess clinician and patient reported aesthetic outcomes and determine the optimal timing of BR in view of post-mastectomy radiotherapy, in breast cancer survivors., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Purpose: We aim to review the available literature on surgical management of oligometastatic pancreatic ductal adenocarcinoma (PDAC), in order to assess the clinical outcomes and intraoperative parameters of the different strategies., Methods: A systematic literature search was performed in PubMed database, in accordance with the PRISMA guidelines. Nine studies met the inclusion criteria incorporating 401 patients., Results: Perioperative mortality was as low as 0%, regarding resection of pancreatic cancer combined with synchronous metastasectomy., Conclusions: Currently, postoperative overall survival and progression-free survival have increased compared to previous trials. Nevertheless, the lack of precise operative indications delays the enhancement of survival rates. Well-designed, randomized controlled studies, assessing pancreatic surgery combined with metastasectomy, are necessary to further assess their clinical outcomes.

- Abstract
Purpose: Glucose-6 phosphate dehydrogenase (G6PD) deficiency has an estimated prevalence of 5 -7.5% of the global population. Administration of some drugs in G6PD deficient patients may result in clinical conditions of varying severity, including potentially fatal sequels. For these reasons, in case of G6PD deficiency, the use of high dose toxic chemotherapy regimens in potentially curable malignancies with associated risk of tumor lysis syndrome, such as in advanced germ cell tumors, raises both physicians' preoccupations and issues for safeguard patients' health. Nonetheless no systematic information is actually available for safety in premedication to be administered, chemotherapy regimens adopted, and supportive care drugs needed to be provided in some particular situations., Methods: We present a case of a patient with metastatic testicular cancer and known g6pd deficiency, admitted in our department. We also performed a literature review in tree medical libraries searching for articles addressing the overmentioned security issues., Results: Available literature is particularly scant. nonetheless, there is no evidence contradicting the administration of cytotoxic chemotherapy to G6PD deficient individuals. Our patient was able to complete the preplaned chemotherapy cycles, without any complications., Conclusion: Given the absence of data supporting the limitation of chemotherapy to G6PD deficient patients, the latter should not be deprived of the indicated antineoplastic treatment. However, certain premedication agents must be avoided. Continuous patient monitoring during treatment may alleviate physicians' and patients' anxiety and preoccupations.

- Abstract
Introduction: The safety of upper gastrointestinal cancer patients in the SARS-CoV-2 outbreak is extremely important and most surgeons need to establish a contingency management., Aim: In this study, we present the surgical outlines of patients suffering from upper gastrointestinal cancers., Materials and Methods: Data were obtained from PubMed, Cochrane Database of Controlled Trials, and SCOPUS of reports up to September 2020., Results: The COVID-19 outbreak makes surgical procedures extremely difficult to be performed. The most common criteria to prioritize patients for surgical treatment are stage, tumor biology, presence of tumor-related symptoms, the risk of tumor to become non-resectable, and time interval from neoadjuvant therapy. The multidisciplinary teams can help assigning a priority level to each clinical case., Conclusion: We have to continue providing treatment to oncologic patients in the face of COVID-19 uncertainty, with higher caution and responsibility in order to develop a safer and more effective personalized treatment plan.

- Abstract
For patients diagnosed with cancer who have previously received an organ transplant, radiotherapy represents a challenging clinical scenario without well established care algorithms. Immunosuppressive therapy can be a cause for concern among clinicians treating this category of patients. Potential immune modulation following irradiation could affect recipient organ tolerance and the outcomes of the transplantation itself. The main aim of this systematic review was to define the safety and effectiveness of radiotherapy in patients diagnosed with cancer who have previously received an organ transplant. We searched PubMed and Embase for articles published between Jan 1, 1995, and April 30, 2020 for studies in patients who had undergone radiotherapy for post-transplantation malignancies. The Review is framed by the PICO (population, intervention, control, and outcomes) criteria, and primarily focuses on modern treatment techniques., (Copyright © 2021 Elsevier Ltd.

- Abstract
Background: The continuously increasing survivorship of female breast cancer makes the monitoring and improvement of patients' quality of life ever so important. While globally there is a growing body of research on health-related quality of life 1 year after surgical treatment for non-metastatic breast cancer, up-to-date information regarding Greek patients is scarce., Objective: To measure the level of QoL of non-metastatic BC survivors in Greece 1 year after surgery., Methods: A sample of 200 female breast cancer survivors aged 18 to 75, who followed up as outpatients in five public hospitals were included in this cross-sectional study. All recruited patients agreed to participate in the study (100% response rate). Quality of life data were collected through the EORTC QLQ-C30 as well as BR23 questionnaires., Results: Cronbach's alpha for all scales of the two questionnaires was from 0.551 to 0.936 indicating very good reliability. According to the Multiple Linear Regression, older patients showed a lower future perspective (p = .031), with those living in rural areas, which was associated with more financial difficulties (p = .001). Women with tertiary education and those who had been hospitalized in a university hospital recorded better on global health status (p = .003 and .000 respectively). Patients who underwent chemotherapy reported better scores in the emotional function sub-scale (p = .025). Women with reconstruction and at least one complication appeared to have significantly better scores in future perspective and social function (p = .005, .002 respectively)., Conclusions: Breast cancer survivors were found to have an overall good quality of life, functioning/symptoms scores and were satisfied with the provided care.

- Abstract
Purpose: SBRT demonstrated to increase survival in oligometastatic patients. Nevertheless, little is known regarding the natural history of oligometastatic disease (OMD) and how SBRT may impact the transition to the polymetastatic disease (PMD)., Methods: 97 liver metastases in 61 oligometastatic patients were treated with SBRT. Twenty patients (33%) had synchronous oligometastases, 41 (67%) presented with metachronous oligometastases. Median number of treated metastases was 2 (range 1-5)., Results: Median follow-up was 24 months. Median tPMC was 11 months (range 4-17 months). Median overall survival (OS) was 23 months (range 16-29 months). Cancer-specific survival predictive factors were having further OMD after SBRT (21 months versus 15 months; p = 0.00), and local control of treated metastases (27 months versus 18 months; p = 0.031). Median PFS was 7 months (range 4-12 months). Patients with 1 metastasis had longer median PFS as compared to those with 2-3 and 4-5 metastases (14.7 months versus 5.3 months versus 6.5 months; p = 0.041). At the last follow-up, 50/61 patients (82%) progressed, 16 of which (26.6%) again as oligometastatic and 34 (56%) as polymetastatic., Conclusion: In the setting of oligometastatic disease, SBRT is able to delay the transition to the PMD. A proportion of patients relapse as oligometastatic and can be eventually evaluated for a further SBRT course. Interestingly, those patients retain a survival benefit as compared to those who had PMD. Further studies are needed to explore the role of SBRT in OMD and to identify treatment strategies able to maintain the oligometastatic state.

- Abstract
Purpose of Review: Patients with cancer are at high risk for thrombotic events, mainly deep vein thrombosis and pulmonary embolism. Low-molecular-weight heparins (LMWHs) and direct oral anticoagulants (DOACs) are among the current treatment options for cancer-associated thrombosis (CAT). We assessed real world data (RWD) regarding treatment patterns of CAT from 1 September 2018 to 31 January 2020., Recent Findings: RWD showed that LMWHs were the most common initial anticoagulation treatment for CAT. Based on these data DOACs had a lower risk of recurrent venous thromboembolism compared with LMWHs and warfarin. However, the selection bias and the small number of patients in these studies might explain this difference and these limitations should be taken into consideration. Moreover, there was no statistical difference regarding adverse events during anticoagulant treatment between LMWHs and DOACs with the limitations of RWD. As far as the duration of the treatment is concerned, the adherence ranged from 100% to 67.3% at 6 months., Summary: The current review of RWD illustrates that LMWHs and DOACs are used for the treatment of CAT. LMWHs are most commonly used for the initial management of CAT. Data regarding recurrence of CAT, adverse events, compliance and duration of anticoagulant treatment should be analyzed with caution as RWD are observational studies with many limitations. Further research is needed to elucidate the best algorithm for the management of CAT.

- Abstract
Aim: The malignant psoas syndrome (MPS) is a rare and complex cancer-related clinical entity, with a significant impact on cancer patients' quality of life. The literature describing malignant infiltration of the psoas muscle as well as its management is limited. The primary endpoint of the study was the assessment of pain relief in symptomatic terminal-stage MPS patients., Materials and Methods: Patients underwent hypofractionated (two- or three-dimensional conformal) radiotherapy as palliative treatment. A dose of 42.5 Gy in 17 daily fractions (2.5 Gy/fraction) was prescribed. Pain response was measured before 3 and 6 months after radiation delivery., Results: Between May 1992 and April 2019, eight patients were treated. The median age was 75 years (range: 59-87 years). All patients had distant metastatic disease at the time of treatment. We found a significant pain relief (median duration of response of 105 days) and an improvement in health-related quality of life., Conclusions: Radiotherapy had a favorable outcome and can be considered an effective analgesic treatment in case of painful MPS., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Indian Journal of Palliative Care.)

- Abstract
Background: During these last years, new agents have dramatically improved the survival of the metastatic patients. Oligometastases represent a continuous field of interest in which the integration of metastases-directed therapy and drugs could further improve the oncologic outcomes. Herein a narrative review is performed regarding the main rationale in combining immunotherapy and target therapies with SBRT looking at the available clinical data in case of oligometastatic NSCLC, Melanoma and Kidney cancer., Material and Method: Narrative Review regarding retrospective and prospective studies published between January 2009 to November 2019 with at least 20 patients analyzed., Results: Concerning the combination between SBRT and Immunotherapy, the correct sequence of remains uncertain, and seems to be drug-dependent. The optimal patients' selection is crucial to expect substantial benefits to SBRT/Immunotherapy combination and, among several factors. A potential field of interest is represented by the so-called oligoprogressed disease, in which SBRT could improve the long-term efficacy of the existing target therapy., Conclusions: A low tumor burden seems to be the most relevant, thus making the oligometastatic disease represent the ideal setting for the use of combination therapies with immunological drugs.

- Abstract
To protect cancer patients from COVID-19 exposure, prioritization strategies are being implemented at global level. Measures include use of tele-health services, deferring elective surgeries, delaying non life-saving therapies, interrupting maintenance and supportive care regimens and suspending screening and regular follow-up visits. Nonetheless, the risk of infection may not always outweigh oncology treatment benefit. Lives of most oncology patients depend on their ability to receive medical, surgical and radiotherapy care. Postponing screening, follow-up and radical surgeries increase patients' risk of developing metastatic disease. A viral pandemic lasts long time and exhibits seasonal and geographical variations. Though vaccines will be available only in the 2021, a global, aggressive, all-embracing and protracted slowdown of oncologic activities will severely jeopardize patients' outcomes. A present international oncologists' panel, ECPC and FAVO, strongly suggest that Hospital measures in a specific geographical area/Nation should be in line with the local epidemic, and restrictions adopted should be adapted and stratified over time.

- Abstract
Background There is no clear evidence on whether radiotherapy (RT) improves treatment result in patients with retroperitoneal sarcomas (RPS). Methods A systematic literature search was performed using PubMed, Scopus and CENTRAL databases. Data were retrieved from published comparatives studies in patients with RPS undergoing surgery alone or RT plus surgery. The primary endpoints were the 5-year OS and the median OS. The secondary endpoints were the recurrence-free survival (RFS) and the R0-resection rate. Continuous outcomes were calculated by means of weighted mean difference (WMD). Results Ten out of 374 articles were analyzed. The median OS and the 5-year survival were significantly increased in patients treated with RT and surgery, compared to patients treated with surgery alone (p < 0.00001, p < 0.001). Median RFS was significantly increased in patients treated with either preoperative (p < 0.001) or postoperative (p = 0.001) RT compared to patients that underwent surgery alone. Finally, median R0-resection rate was similar between the two groups (p = 0.56). Conclusion RT along with radical surgery could be the standard of care in at least a subgroup of patients with RPS.

- Abstract
Purpose: To assess the quality of life (QoL) following palliative radiotherapy (RT) in patients with painful bone metastases., Methods: A literature search limited to English-written publications was carried out, through the Cochrane Central Register of Controlled Trials (November 2018), OvidSP and PubMedCentral (1940-November 2018) databases. Subject headings and keywords included "quality of life"(QoL), "bone metastases", "palliative therapy", "pain" and "radiotherapy". Original articles, literature reviews, trials and meta-analyses revealing alterations in QoL post-RT using ratified measuring tools were examined. Studies referring to other types of metastases (e.g. brain metastases), or to other types of palliative therapy (e.g. the use of bisphosphonates alone), or focusing only on pain, or even reporting QoL only before or only after the use of RT were excluded., Results: Twenty four articles were selected from a total of 1360 articles. Seven trials proceeded to patients' randomization. The most commonly used tool to evaluate QoL was EORTC, followed by Brief Pain Inventory (BPI) and Edmonton Symptom Assessment System (ESAS) questionnaires. All studies showed improvement in symptoms and functional interference scores after RT. The QoL between responders (Rs) and non-responders (NRs) has been juxtaposed in 10 studies. Rs had a significant benefit in QoL in comparison with the NRs., Discussion: Palliative radiotherapy in painful bone metastases improves Rs' QoL.

The integration of immunotherapeutic agents in the treatment of non-small cell lung cancer (NSCLC) has revolutionized the approach of the prevalent type of lung cancer. Although PD-1 and its ligands (PD-L1 and PD-L2) are stimulating molecules of the immune-checkpoint pathway, with primary function to limit inflammatory response and autoimmunity, tumor cells have found a way to exploit these molecules by obtaining the opportunity to respond with PD-L1 expression in cytokine signals and thus to evade immune surveillance. Several immunotherapeutic agents targeting these molecules have already been tested and show quick and remarkable responses and survival prolongation in about 14-20% of chemo-resistant patients in NSCLC, resulting to FDA approval of some PD-1 inhibitors (pebrolizumab, nivolumab), even for first-line treatment of patients with metastatic NSCLC whose tumors have high PD-L1 expression (pebrolizumab). Regarding to the prognostic value of PD-L1 and PD-1 expression as biomarkers in NSCLC, the results still remain contradictory. However, the elevated expression of PD-L1 has been correlated with higher efficacy of the various immunotherapeutic agents, implying a high predictive value of this biomarker, even if the truth about specificity and sensitivity of the aforementioned molecules is generally more complicated.

- Abstract
Purpose: The standard treatment of rectal cancer is surgery along with preoperative radiotherapy, administered alone or in combination with chemotherapy. Preoperative chemoradiotherapy (preCRT) is widely used as it allows better local control and the use of sphincter-saving surgery. Pathological response after preCRT has been shown to be a significant prognostic factor of rectal cancer recurrence and survival. In this review we will assess the value of Hypoxia Induced Factor 1α (HIF-1α), Carbonic Anhydrase IX (CA-9) and Glucose Transporter 1 (GLUT-1) genes as predictive markers of the course of local advanced rectal cancer in patients who underwent pre-CRT., Methods: We searched studies, from Pubmed and in English language, obtained the information by using "HIF-1 alpha", "Carbonic Anhydrase IX (CA-9)", "Glucose Transporter 1 (GLUT-1)" and "rectal cancer" as key words., Results: 27 relevant articles were retrieved in initial stage. After full-text review, 13 articles were selected for the final analysis., Conclusions: HIF-1α, GLUT-1 and CA-IX may be connected with tumor response to preCRT, however, there is still skepticism towards their clinical use as predictors of outcome. Therefore, there is a need to conduct larger and more extensive cohort studies in order to find whether these predictors can be used in practice.

- Abstract
Purpose: To evaluate the use of percutaneous computed tomography (CT)-guided localization of suspicious intrapulmonary nodules with hook wire prior to video-assisted thoracoscopic surgery (VATS)., Methods: From April 2010 to February 2011, 15 patients with suspicious subpleural pulmonary nodules underwent preoperative CT-guided hook wire localization of the lesions, prior to VATS., Results: Histological analysis of the resected suspicious pulmonary nodules revealed malignancy in 12 cases, 2 cases with granulomas and 1 case with bronchiolitis obliterans organizing pneumonia (BOOP). Better results were achieved with the double-thorn hook wire. Conversion to thoracotomy was necessary in the patient with BOOP, due to limited hemorrhage at the site of the lesion., Conclusion: Preoperative CT-guided nodule localization using hook wire fixation is a useful and safe technique that helps in the precise localization of suspicious lesions, reduces the operation time, the postoperative complications, and the hospitalization.

- Abstract
Purpose: Several adjuvant approaches are regarded as available options in the management of localized, resectable gastric cancer .The objective of our study was to evaluate multiple field and anteroposterior conformal technique., Methods: Ninety-seven patients received three dimensional conformal (3DCRT) postoperative adjuvant radiation therapy for gastric carcinoma. Thirty-five patients received anteroposterior (AP/PA) fields (Group B), while 62 patients were irradiated with multifield technique (Group A). Their ages ranged between 29-85 years. The objective of the study was to evaluate the quality of life (QoL) for all patients after the completion of radiotherapy using the QLQ-C30 of the EORTC questionnaire (European Organization for Research and Treatment of Cancer) and to investigate any measurable differences between those two radiation techniques according to QUANTEC criteria and the radiotoxicity., Results: In terms of QUANTEC criteria, the multifield technique was superior concerning the left kidney (p=0.025), right kidney (p<0.001), spinal cord (p<0.001) and planning target volume (PTV) coverage (p<0.001). According to EORTC/ RTOG toxicity criteria, the rate of diarrhea was higher in AP/ PA technique (p=0.028). In terms of QLQ-C30, the multifield technique was superior concerning appetite loss (p=0.022), diarrhea (p=0.046) and global QoL (p<0.001)., Conclusion: On the basis of QLQ-C30 questionnaire, EORTC/ RTOG toxicity and dosimetric parameters, the present report has shown that the three dimensional multifield conformal radiotherapy is superior compared to AP-PA techniques.

- Abstract
Background: Many studies have been performed over time in order to determine the reliability of metabolic rate prediction equations., Purpose: To evaluate the agreement, in terms of bias, absolute bias and accuracy between metabolic rate prediction equations and measured metabolic rate using indirect calorimetry system (IC), investigating also the factors affecting this agreement., Methods: The anthropometric features of 383 Caucasian participants of all Body Mass Index (BMI) classes were recorded and Resting Metabolic Rate (RMR) was measured by using the IC Fitmate portable device. The resulting values were compared with the predictive values of Harris & Benedict, Schofield, Owen, FAO-WHO-UNU, Mifflin and Harrington equations., Results: A closer approximation in agreement was obtained using the Harrington equation (based on BMI, age and gender). The equations using variables, such as weight, height, age and gender demonstrated higher agreement than the equations using merely weight and gender. Higher educational level was associated with normal weight, while higher calorific ratio was found in the class of normal-weighted individuals. An inverse relationship between ΒΜΙ and RMR was also observed and a logarithmic equation for calculating RMR was created, which was differentiated in relation to BMI classes, using the weight and gender variables., Conclusion: A better measurement agreement between RMR prediction equations and IC may be achieved due to BMI consideration. The present findings contributed to a better understanding of the measured parameters, confirming the inverse relationship between BMI and RMR. Age group and gender variables may also exert significant role on the bias response of some RMR equations., Competing Interests: Not applicable.The authors declare that they have no competing interests.Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

- Abstract
Background/aim: Radiation dermatitis is observed in 95% of breast cancer patients receiving radiotherapy. The aim of this study was to explore the correlation between protein expression in tumor cells and the risk of developing radiation dermatitis., Patients and Methods: Breast cancer patients receiving postoperative radiotherapy were included in this study. Tumor specimens from 122 patients were examined by immunohistochemistry for the expression of Ki67, ataxia telangiectasia mutated (ATM) kinase, hypoxia-inducible factor-1-alpha (HIF-1a), inducible nitric oxide synthase (iNOS), and a-glucosidase (aGluc). The findings were correlated with the occurrence and severity of radiation dermatitis (Radiation therapy oncology group-RTOG grading scale), taking into consideration body weight and skin type (Fitzpatrick system). Data were explored further via pathway and network analyses., Results: Correlation of radiation dermatitis (RTOG scale) with the observed increased expression of Ki67, ATM, iNOS, HIF-1a and aGluc, failed to reach statistical significance when skin type and/or body weight were considered. Network interactions of proteins involved in tumor growth (Ki67, ATM) and/or affect the oxidation state of the cell (HIF-1a, iNOS, aGluc) were revealed, that may contribute to the risk of developing acute radiation dermatitis., Conclusion: Correlation of the increased expression of the studied proteins and the occurrence and severity of radiation dermatitis in women undergoing postoperative radiotherapy, failed to reach statistical significance. Pathway and network analyses predicted that vasodilation and angiogenesis may contribute to radiation-induced dermatitis via mechanisms that need to be further explored. Our strategy serves as a paradigm for coupling histopathological data to molecular findings and network analyses for risk assessment in the clinic., (Copyright© 2018, International Institute of Anticancer Research (Dr. George J.

- Abstract
Purpose: The purpose of the present article was to investigate the health related quality of life (QoL) of young women with breast cancer., Methods: For the purposes of this article, we reviewed the literature via the electronic databases Pubmed, Scopus and Google Scholar. Key words used were breast cancer, young women, health related quality of life, and quality of life., Results: Young women reported fatigue, pain in the breast and hand problems with lymphedema as the most frequent physical effects of treatment. Other physical problems were the not periodic and painful menses, vaginal dryness and loss of libido. Many young women had depressive symptoms such as depressed mood, helplessness, hopelessness, sleep loss, psychomotor retardation and disorders of appetite. There were often concerns about the health monitoring and self-image, while they were anxious if they will have a baby in the future or if they can nurture the existing ones. Many problems arose in the career of young women. They faced discrimination in the labor supply and/or layoff because they were considered unable to do their job effectively. In addition, they reported isolation problems and feeling different from other women of similar age., Conclusions: Young women consider that their healthrelated QoL is worse compared with older women. Young women worry about their future, with particular reference to their role as mothers and especially to children-bearing. The free screening and non-exclusion of young women is particularly important for breast cancer prevention and women's well-being.

- Abstract
Background: Unique features and worse outcomes have been reported for cancers among adolescents and young adults (AYAs; 15-39 years old). The aim of this study was to explore the mortality and survival patterns of malignant central nervous system (CNS) tumors among AYAs in Southern-Eastern Europe (SEE) in comparison with the US Surveillance, Epidemiology, and End Results (SEER) program., Methods: Malignant CNS tumors diagnosed in AYAs during the period spanning 1990-2014 were retrieved from 14 population-based cancer registries in the SEE region (n = 11,438). Age-adjusted mortality rates were calculated and survival patterns were evaluated via Kaplan-Meier curves and Cox regression analyses, and they were compared with respective 1990-2012 figures from SEER (n = 13,573)., Results: Mortality rates in SEE (range, 11.9-18.5 deaths per million) were higher overall than the SEER rate (9.4 deaths per million), with decreasing trends in both regions. Survival rates increased during a comparable period (2001-2009) in SEE and SEER. The 5-year survival rate was considerably lower in the SEE registries (46%) versus SEER (67%), mainly because of the extremely low rates in Ukraine; this finding was consistent across age groups and diagnostic subtypes. The highest 5-year survival rates were recorded for ependymomas (76% in SEE and 92% in SEER), and the worst were recorded for glioblastomas and anaplastic astrocytomas (28% in SEE and 37% in SEER). Advancing age, male sex, and rural residency at diagnosis adversely affected outcomes in both regions., Conclusions: Despite definite survival gains over the last years, the considerable outcome disparities between the less affluent SEE region and the United States for AYAs with malignant CNS tumors point to health care delivery inequalities. No considerable prognostic deficits for CNS tumors are evident for AYAs versus children. Cancer 2017;123:4458-71. © 2017 American Cancer Society., (© 2017 American Cancer Society.)

Purpose: The purpose of this study was to present the controversial role of adjuvant radiotherapy to a 72-year-old male patient with Masaoka stage II thymoma and coronary artery bypass and to review the relevant literature., Methods: The data were collected by relevant studies on PubMed and EMBASE. Articles up to March 2017 were included., Results: Although the radiation-induced vascular injury to the internal thoracic artery and its suitability for grafting in a patient who is candidate for coronary artery bypass is documented, the possible catastrophic effect of adjuvant radiotherapy to existing grafts in a patient with prior bypass surgery has not been fully investigated., Conclusion: The application of radiotherapy in a patient with R0 stage II thymoma is currently considered of 2B level of evidence but its potential occlusive effect to an underlying coronary graft may dramatically affect the survival of the patient and accordingly drop the level of evidence of its use.

Purpose: Τo investigate the potential diagnostic and prognostic role of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA 19-9) serum levels in non-small cell lung cancer (NSCLC)., Methods: One hundred consecutive patients with newly diagnosed primary NSCLC were included in this study (88 men and 12 women). Blood was drawn before any kind of treatment and the collected serum was processed using chemiluminescence in order CEA and CA 19-9 levels to be measured., Results: No significant associations between CEA or CA 19-9 levels and any tested clinical and pathological parameter were detected. Moreover, CEA levels did not seem to affect survival. On the other hand, patients with high CA 19-9 values (≥37 IU/ml) (median survival: 8 months) had a shorter overall survival than patients with low CA 19-9 values (<37 IU/ml) (median survival: 13 months) (p=0.026). However, CA 19-9 levels did not remain an independent prognostic factor in the multivariate survival analysis (p=0.114)., Conclusion: CEA and CA 19-9 serum levels do not seem to have any diagnostic role in NSCLC. With regard to their prognostic role, CEA values do not seem to affect the prognosis in NSCLC. However, high CA 19-9 values are associated with worse prognosis.

Purpose: Hypothalamic-pituitary axis is susceptible to radiotherapy, causing endocrine disorders to childhood cancer survivors. We conducted a systematic review in order to assess the radiation-induced toxicity that leads to hormone secretion abnormalities and their severity in children with brain tumors., Methods: The data were collected by relevant studies on PubMed and EMBASE. Articles up to December 2016 were included. We selected studies which focused on children patients (<18 yr old) with brain tumors treated with radiotherapy and the consequences for their endocrine system., Results: Growth hormone (GH) deficiency was the most common post-irradiation abnormality among children cancer survivors, followed by gonadotrophin (GT), thyroid stimulating hormone (TSH), corticotropin (ACTH) and prolactin (PRL) disorders., Conclusions: The age of the patient, total radiotherapy dose, number of fractions, fraction size and the duration of treatment seem to determine the severity of these disturbances.

- Abstract
Purpose: Dermatomyositis (DM) represents an auto-immune inflammatory myopathy. In this review, we analyzed the incidence of DM as a clinical manifestation highlighting the peculiar clinical and treatment characteristics of this disease when occurring in the context of different malignancies., Methods: A systematic literature review was performed based on database search in PubMed/Medline and included English articles until December 2016., Results: In up to 20% of cases DM appears as a paraneoplastic syndrome associated with multiple malignancies such as ovarian, breast, prostate, lung, nasopharyngeal and colorectal cancer, and non-Hodgkin lymphomas. It can be presented either before, in the time, or after cancer diagnosis. Systemic sclerosis and mixed connective-tissue disease represent common coinciding disorders. Particular caution should be given in the radiotherapy because the microvascular endothelial radiation damage and autoimmune inflammatory collagen vascular disease caused by DM may be additive. There is a higher risk of late toxicity in the presence of other concurrent vascular diseases, including diabetes, hypertension or administration of chemotherapy. Prednisone represents the first-line treatment option but immunosuppressive drugs such as azathioprine and methotrexate may also be incorporated in the therapeutic armamentarium especially when DM is associated with malignancy. Intravenous immunoglobulin could be a promising alternative in prednisone-resistant cases. The effectiveness of therapies with antigen-specific agents such as monoclonal antibodies is currently under investigation., Conclusions: Timely diagnosis coupled with a treatment plan focused on muscular endurance and improvement of skin lesions and other symptoms offer a favorable response to therapy along with the achievement of a higher quality of life for these patients.

- Abstract
Background/aim: Lung cancer is the first cause of cancer related deaths in both males and females. Epithelial-mesenchymal transition (EMT) is a reversible process by which epithelial cells transform to mesenchymal stem cells by losing their cell polarity and cell-to-cell adhesion, gaining migratory and invasive properties. High levels of E-cadherin are expressed in epithelial cells, whereas mesenchymal cells express high levels of N-cadherin, fibronectin and vimentin. The aim of this study was to evaluate the correlation between E-cadherin and vimentin expression and their clinical significance in non-small cell lung cancer (NSCLC)., Materials and Methods: The immunohistochemical expression of E-cadherin, vimentin and Ki-67 was performed on tissue microarrays from NSCLC specimens obtained from 112 newly- diagnosed cases and were studied using classical pathological evaluation. Associations between E-cadherin, vimentin and Ki-67 expression, clinicopathological variables and survival were analyzed. In all cases, a value of p≤0.05 was considered significant., Results: Low E-cadherin expression was significantly correlated with tumor necrosis (p=0.019). Moreover, there was a trend for correlation between high E-cadherin expression and better overall survival (hazard ratio=1.02, and 95% confidence interval=0.45-1.87, p=0.091). There was also a significant negative correlation between vimentin expression and overall survival (hazard ratio=1.13, and 95% confidence interval=0.78-1.65, p=0.026). Additionally, there was a significant negative correlation between vimentin expression and grade I tumors (p=0.031). Finally, a positive correlation trend between vimentin expression and Ki-67 was found (p=0.073)., Conclusion: High E-cadherin and low vimentin expression correlate with better prognosis and overall survival., (Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

Purpose: Xerostomia after radiation therapy for head and neck (H&N) cancer has serious effects on patients' quality of life. The purpose of this study was to validate the Greek version of the self-reported eight-item xerostomia questionnaire (XQ) in patients treated with radiotherapy for H&N cancer., Methods: The XQ was translated into Greek and administered to 100 XQ patients. An exploratory factor analysis was performed. Reliability measures were calculated. Several types of validity were evaluated. The observer-rated scoring system was also used., Results: The mean XQ value was 41.92 (SD 22.71). Factor analysis revealed the unidimensional nature of the questionnaire. High reliability measures (ICC, Cronbach's α, Pearson coefficients) were obtained. Patients differed statistically significantly in terms of XQ score, depending on the RTOG/EORTC classification., Conclusion: The Greek version of XQ is valid and reliable. Its score is well related to observer's findings and it can be used to evaluate the impact of radiation therapy on the subjective feeling of xerostomia.

- Abstract
Neuroendocrine tumors of the gastrointestinal tract are rare neoplasms. Rectal neuroendocrine tumors consist approximately the 5%-14% of all neuroendocrine neoplasms in Europe. These tumors are diagnosed in relatively young patients, with a mean age at diagnosis of 56 years. Distant metastases from rectal neuroendocrine tumors are not very common. Herein we describe a case of a rectal neuroendocrine tumor which metastasized to the lung, mediastinum and orbit. This case underscores the importance of early identification and optimal management to improve patient's prognosis. Therefore, the clinical significance of this case is the necessity of physicians' awareness and education regarding neuroendocrine tumors' diagnosis and management.

- Abstract
Purpose: Intensity Modulated Radiation Therapy (IMRT) is nowadays the treatment of choice, in terms of technique, for either head & neck or prostate cancer. With this paper, we are sharing our experience for the first inplementation of IMRT planning in the public sector in Greece, and especially in the Aretaieion University Hospital of Athens., Methods: From May 2013 until January 2014 four prostate and four head & neck cancer patients were evaluated in the present study. We used the ONCENTRA IMRT treatment planning with a step and shoot technique in a SIEMENS ONCORE Linac. The dose verification method used was based on the delta4(PT) Pre-Treatment volumetric quality assurance system, by Scadidos., Results: In all cases, the Relative Standard Deviation between the prescribed and the calculated average dose received by the target volume was less than 5%, while the γ-index was more than 90%. The acute toxicity was low and equivalent to published data with IMRT technique., Conclusion: In conclusion, the first implementation of IMRT technique in the Medical School of Athens was feasible and safe as well as in terms of dose verification. The IMRT technique is already in clinical use and further results with long term radiation induced toxicity will be reported.

- Abstract
Aim: To evaluate the effect of chemotherapy to the acute toxicity of a hypofractionated radiotherapy (HFRT) schedule for breast cancer., Methods: We retrospectively analyzed 116 breast cancer patients with T1, 2N0Mx. The patients received 3-D conformal radiotherapy with a total physical dose of 50.54 Gy or 53.2 Gy in 19 or 20 fractions according to stage, over 23-24 d. The last three to four fractions were delivered as a sequential tumor boost. All patients were monitored for acute skin toxicity according to the European Organization for Research and Treatment of Cancer/Radiation Therapy Oncology Group criteria. The maximum monitored value was taken as the final grading score. Multivariate analysis was performed for the contribution of age, chemotherapy and 19 vs 20 fractions to the radiation acute skin toxicity., Results: The acute radiation induced skin toxicity was as following: grade I 27.6%, grade II 7.8% and grade III 2.6%. No significant correlation was noted between toxicity grading and chemotherapy (P = 0.154, χ(2) test). The mean values of acute toxicity score in terms of chemotherapy or not, were 0.64 and 0.46 respectively (P = 0.109, Mann Whitney test). No significant correlation was also noted between acute skin toxicity and radiotherapy fractions (P = 0.47, χ(2) test). According to univariate analysis, only chemotherapy contributed significantly to the development of acute skin toxicity but with a critical value of P = 0.05. However, in multivariate analysis, chemotherapy lost its statistical significance. None of the patients during the 2-years of follow-up presented any locoregional relapse., Conclusion: There is no clear evidence that chemotherapy has an impact to acute skin toxicity after an HFRT schedule. A randomized trial is needed for definite conclusions.

- Abstract
Purpose: To prospectively assess the efficacy of the selective serotonin inhibitor escitalopram on painful bone metastases, in combination with external beam irradiation., Methods: Forty-three patients with cancer metastatic to bone and suffering from depression were treated with 3 Dimensional Conformal Radiotherapy (3DCRT) (30 Gy; 3 Gy/fraction, 5 days/week) combined with escitalopram (20 mg/day). Pain relief was evaluated with Wong/Baker Faces Pain Scale. The patients reported outcome using a RTOG-EORTC quality-of-life self-questionnaire (QLQ-C30 v3.0) and the status of depression according to Hamilton Scale (HAM-17). The assessment was performed at baseline and 6-8 weeks after radiotherapy., Results: Patients treated with radiotherapy and escitalopram tended to show a good response to pain and improvement of their quality of life., Conclusions: Though our data concerned a rather small number of patients, addition of escitalopram to 3DCRT accomplished a high clinical benefit rate on neuropathic pain from bone metastasis.

- Abstract
Purpose: The primary endpoint was to assess the late toxicity of a hypofractionated radiotherapy schedule in relation to radiation parameters concerning the rectum and bladder. The second endpoint was to assess a composite of biochemical and clinical failure., Methods: Sixty-four prospectively selected patients diagnosed with localized low risk prostate cancer, Gleason score (GS) <7, PSA <10, and T1-2N0, were treated with external 3- dimensional conformal radiotherapy (3D-CRT). Patients received 57.75 Gy in 21 daily fractions of 2.75 Gy/fraction., Results: Late gastrointestinal (GI) toxicity was as follows: grade 0: 47 (73.4 %) patients, grade 1: 12 (19.2 %), grade 2: 4 (6.3%), and grade 3: 1 (1.6%). There was a significant correlation between D50, V70 and EORTC/RTOG late rectal toxicity score (p<0.001 and p=0.006, respectively). Grade 1 and 2 late bladder toxicity was seen in 4.7 and 1.6% of the patients, respectively. With a median follow up of 18 months no biochemical relapse was observed., Conclusion: The present study supports the use of hypofractionated radiation therapy which showed a high therapeutic ratio with acceptable toxicity and no biochemical relapse during follow-up.

- Abstract
Background: Breast cancer (BC) in males is a rare disease and comprises 0.5-1% of all BC cases. Due to its rarity, there are limited data regarding risk factors, biology and relevant treatment., Aim: A prospective observational study of demographic, clinical and histological characteristics of serially-admitted men with breast cancer was carried out from 1999 to 2009., Patients and Methods: Data were recorded and analyzed from a database including 1,315 cases of BC. Registered data concerned age, initial presentation, family and lifestyle history (risk factors), histological features, phenotypic subtypes and TNM staging., Results: Twenty two men with BC were identified, with a median age of 63 years. The most common initial presentation was a palpable lump in 12 patients, nipple contraction in three and ulceration in three. According to their medical history, nine men were overweight, 10 suffered from hypertension and 12 were smokers. The most prevalent phenotype was luminal-A followed by triple-negative type. BC in none of the cases was HER 2-amplified. The majority of cases were grade II or III and stage II or III., Conclusion: In the present small study, we confirm that BC in males is rare. It is a disease of middle-age and presents at advanced stages. Most of patients had 1-3 risk factors for BC. Expression of hormonal receptors occurs in the majority of BC tumors in males and with rarity in HER 2 amplification.

Background/aim: The evaluation of radiotherapy toxicity in oncologic IBD patients. Defining the optimal patient and treatment factors that would be able to reduce the risk to organs., Materials and Methods: A review of all published radiotherapy trials was performed to identify the clinical and treatment factors of inflammatory bowel disease's patients treated for different solid tumors., Results: Overall, acute (Grade ≥ 3) gastrointestinal complications attributable to RT ranged between 20-21% of the treated patients. A late Grade ≥ 3 gastrointestinal toxicity was developed in a range between 8-29%., Conclusion: A special attention should be given to the description of IBD location, activity status, concurrent chemotherapy, irradiation dose and technique, in order to minimize post-irradiation morbidity. It is not easy to distinguish late morbidity attributable to radiotherapy due to the IBD itself.

- Abstract
Introduction: In radiotherapy, a team of highly specialised professionals co-operate in planning and delivery of treatment and are responsible for the effectiveness and safety of the service. The aim of this article was to present the necessity and features of a quality assurance (QA) program in radiotherapy through literature review., Methods: A search was carried out in Scirus, Medline/ PubMed databases using the keywords "clinical oncology", "radiation oncology", "radiotherapy", "oncology practice", "quality assurance" and "quality of care". Twenty-nine articles were chosen covering the period 1995-2007. Further information was obtained from the Royal College of Radiologists' UK website., Results: QA was relevant to three aspects of radiotherapy: 1) clinical, involving resources (staffing and equipment), procedures (treatment planning, follow up) and results (tumor control, toxicity); 2) medical physics, involving the measurements necessary for the safety and precision of equipment; and 3) technical, involving the accurate plan implementation and the smooth function of treatment machines. International guidelines defined best practice in diagnosis and treatment of cancer patients. Moreover, the principles of quality management provided the tools not only for a reasonable use of limited resources but also for continuous improvement of organisations towards patient- centred services., Conclusion: Quality in radiotherapy is a dynamic concept that needs to be measured and re-evaluated using scientific methods and feedback by the users. Successful implementation of a QA program in radiotherapy requires expertise, training and co-ordination in an environment of teamwork.

- Abstract
Unlabelled: The present review aims at providing an assessment of the clinical significance of Biphosphonates (BPs) in the treatment of patients with cancer., Materials and Methods: A systematic literature review was performed based on database search in PubMed/Medline and included articles up to August 2013., Results: BPs can reduce, delay, and prevent complications related to bone metastases. They improve mobility, functionality, pain, and quality of life. They limit survival of any inactive cancer cells in the microenvironment of the bone marrow, contributing to their death from anti-neoplastic treatments. Moreover, they limit and delay bone morbidity due to osteoporosis related to hormonotherapy in breast and prostate cancer. Finally, benefits can be derived from the combination of BPs with radiotherapy in bone density, recalcification, opioid use, and patient's quality of life and performance status., Conclusion: The contribution of BPs in the course of certain neoplasms is preventive and synergistic to other treatments.

- Abstract
Purpose: The purpose is to evaluate the feasibility, efficacy, and the toxicity of three-dimensional conformal radiotherapy (3DCRT) in patients with advanced hepatocelluar carcinoma (HCC) and inferior vena cava tumor thrombosis (IVCTT)., Methods: Between 2007 and 2012, in a retrospective way, 9 patients (median age 69 years) with advanced HCC and IVCTT unfit for surgery, radiofrequency ablation, embolization, or chemotherapy were treated with three-dimensional conformal radiotherapy (3DCRT). The radiotherapy volume included both primary tumor and IVTT. The radiotherapy schedule was 50-52 Gy in 2 Gy fractions. Overall survival (OS), response to radiotherapy, visual analogue scale (VAS), and toxicity were assessed., Results: All patients demonstrated a response rate up to 60%. During radiotherapy, 3 patients experienced grade 1 nausea/vomit toxicity. All patients demonstrated an elevation of the liver enzymes (3 patients with grade 1 and 6 patients with grade 2). The mean VAS-score was decreased from 6.11 to 3.11, while the median overall survival was 24 months., Conclusion: 3DCRT achieves a very high local control rate and is suitable for patients with HCC and IVTT, while the documented radiation induced toxicity is moderate. It can be recommended for palliation in patients unable to undergo curative therapies.

- Abstract
Background: The aim of the study was to evaluate the efficacy, as well as the acute and late toxicity of an accelerated hypofractionated 3DCRT schedule as radical treatment in patients with organ confined glottic cancer cT1-2N0., Patients and Methods: Between June of 2004 and September 2010, 47 retrospectively selected patients (29 males, 18 females) diagnosed with organ confined T1 or T2 glottic cancer, were treated with external 3DCRT in an accelerated hypofractionation schedule. The median age was 70 years. A dose of 64.4 Gy in 28 daily fractions was prescribed. The primary study endpoints were to assess the acute and late effects of radiation toxicity, according to the EORTC/ RTOG scale, as well as the therapeutic impact of this schedule in terms of local recurrence., Results: The median follow up was 36 months. At the end of radiotherapy, grade I, II and III acute toxicity was observed in 34, 9 and4 patients, respectively. Late grade I and II toxicity was observed in 25 and in 8 patients respectively. Only two local recurrences were observed, 15 and 24 months post 3DCRT respectively., Conclusions: Our radiotherapy schedule achieves a high locoregional control rate with the advantage of voice preservation. The proposed hypofractionated schedule can be recommended as a standard radiotherapy treatment, since these results are comparable with those of conventional fractionation schedules.

- Abstract
Purpose: We present the case of a patient treated for intracranial germ cell tumor in which elements of craniopharyngioma were found in the residual tumor mass., Findings: A 17 year old patient presented with a history of secondary amenorrhea. She deteriorated with headache and left eyelid drop, paresis of the abducent nerve and convergent strabismus (Parinaud syndrome). β-HCG was 722mIU/ml and pregnancy was excluded. AFP was 6322 ng/ml. Brain CT scan showed a large endosellar tumor to the hypersellar region. There was left papillary atrophy. MRI confirmed a tumor to dorsum sellae. Primary germ cell intracranial tumor was diagnosed. Severe clinically evident pituitary failure developed with signs of increased intracranial pressure and brain edema as well as diabetes insipidus, while AFP increased to 15786,3ng/ml. Urgent treatment with combination chemotherapy including cisplatin etoposide and bleomycin (ΡEB) was administered for 4 courses. As a result her clinical condition improved and tumor markers dropped but nevertheless did not become normal. In addition CT scans revealed a remaining endocranial mass and therefore the patient was subjected to high-dose chemotherapy followed by autologous stemcell rescue which resulted in complete clinical and biochemical remission. Due to the persisting mass in the area, it was delivered radiotherapy., Conclusions: The above case is extremely rare in worldwide literature. Dysgerminoma may coexist with craniopharyngioma which in fact may be part of a germ cell tumor in the context of dysembryogenesis and benign "teratoma".

- Abstract
Taxanes, both paclitaxel and doxetaxel are the medication of the future in the management of solid tumors. In high risk breast cancer patients, the combination of concurrent paclitaxel and docetaxel chemotherapy with adjuvant radiotherapy is an attractive option to sequential treatment, with potential for enforcing both local and systemic control. This case report examines the tolerance of such treatment. A 54-year-old Greek woman without a relevant medical history, presented with clinical diagnosed breast cancer staged T4NxM0. Neo-adjuvant chemotherapy was initially administered, and paclitaxel was administered concurrently with radiotherapy in order to achieve local control. During the third cycle of paclitaxel the patient developed grade III dermatitis. The tumor showed a reduction in size by 70%, however, chronic cutaneous and subcutaneous changes have not been accessed. In conclusion, adjuvant breast cancer therapy with concurrent standard dose radiotherapy and paclitaxel (175 mg/m
2 ) every three weeks, should be approached cautiously owing to paclitaxel induced dermatitis., Competing Interests: The authors declare that they have no competing interests.- Published
