The new second-generation tyrosine kinase inhibitors (TKIs) have superior survival outcome and worse toxicity profile when compared with first-generation TKIs according to the results of clinical trials. However, there are limited studies that investigate the efficacy and safety of the new generation TKIs in real-world patients. Thus, we aimed to compare the efficacy and safety of the afatinib, an irreversible inhibitor of ErbB family receptor, and first-generation TKIs in real-world patients. We included advanced nonsmall cell lung cancer (NSCLC) patients who had EGFR exon 19del mutation and treated with afatinib or first-generation TKIs as upfront treatment between 2016 and 2020. All patient's information was collected retrospectively. The study cohort was divided as afatinib arm and erlotinib/gefitinib arm. A total of 283 patients at the 24 oncology centers were included. The 89 and 193 of whom were treated with afatinib and erlotinib/gefitinib, respectively. After 12.9 months (mo) of follow-up, the median PFS was statistically longer in the afatinib arm than erlotinib/gefitinib arm (19.3 mo vs. 11.9 mo, p: 0.046) and the survival advantage was more profound in younger patients (

Self-esteem refers to a person's positive and negative attitudes towards the self, and metacognition is an upper system providing awareness and direction of events and mental functions. Coping refers to the specific and psychological efforts used to deal with stressful events or the negative effects of the agents of these. The aim of this study was to evaluate self-esteem, metacognition status and coping attitudes in patients with cancer, which is known to have severely destructive psychological effects.Fifty adult cancer patients who were followed up in the medical oncology clinic between July 2018 and June 2019 and 50 age- and gender-matched healthy controls as control group were included in this study. All the participants were applied with a sociodemographic data form, the Rosenberg self-esteem scale, the Metacognition Assessment Scale, and the Copying Orientation to Problems Experienced (COPE) inventory, and their results were compared between the groups.The groups comprised 50% females with a median age of 58 (33-82) years. The values related to the degree of participation in discussions, problem-focused coping, active coping, planning, and state of emotional vulnerability were low in the cancer patient group compared to the control group (P0.005 for all). The sustaining of their self-image, feeling threatened in interpersonal relationships, and degree of daydreaming were higher, and in the metacognition tests, the positive beliefs related to anxiety, uncontrolled or dangerous negative thoughts, nonfunctional coping, religious coping, joking, reckless behavior, substance use, denial, and mental disengagement scores were higher (P0.05 for all).Self-esteem was lower in cancer patients and upper level cognitive functions and problem-focused coping were determined to be worse compared to healthy controls. In the light of these results, psychosocial support given to cancer patients in this respect could contribute to quality of life and social conformity.

Aim: Metaplastic breast cancer (MBC) is a rare subtype with unusual clinical features. We aimed to analyze treatment results and define patients' characteristic features in our large MBC patient series. Materials and Methods: Fifty-six patients with early MBC who received adjuvant radiotherapy (RT) in our center were included in the study. The age, sex, subtypes of MBC, histopathology, hormone and nodal status, tumor size, and types of treatment were retrospectively provided from hospital records. Results: The median tumor size was 4 (1.3–16.5) cm, and triple-negative MBC cases were 38 (67.8%) of all patients. Axillary nodal involvements were present in 25 (44.6%) patients. The median follow-up time was 45.8 (4.9–130) months; the overall survival (OS) and disease-free survival (DFS) for 5 years were 67% and 64%, respectively. While distant metastases were seen in 15 (26.7%) patients, local recurrences were seen in only 4 patients. The median OS and DFS were higher in patients with ≤5.2 cm tumor than >5.2 cm ([130 vs. 49 months, P = 0.01] and [130 vs. 30 months, P = 0.009], respectively). Nodal involvement, hormone receptor status, surgical treatment, and type of RT had no effect on survival. In multivariate analysis, tumor size was not an independent prognostic factor for OS (P = 0.068; hazard ratio [HR]: 3.4, 95% confidence interval [CI] = 0.91–12.8), whereas age >65 years was found an independent poor prognostic factor for OS ([HR: 4.25, 95% CI: 0.23–0.78, P = 0.021] and DFS [HR: 3.1, 95% CI: 0.02–0. 87; P = 0.04], respectively). Conclusions: Distant metastasis is at the forefront rather than local recurrence in MBC patients. More studies are needed to determine the factors that affect survival independently in MBC.

This study aimed to assess the effect of pretreatment albumin-bilirubin (ALBI) score on treatment outcomes in pancreatic cancer (PC) patients with liver metastasis at the time of diagnosis treated with chemotherapy (CT) in the first-line setting.This was a retrospective study of 273 PC patients ≥18 years of age who had liver metastasis at the time of diagnosis and received CT in the first-line. ALBI score was calculated through the following formula; [(log10 bilirubin (μmol/L)×0.66)+[albumin(g/l)×-0.0852]. Patients were stratified into 3 categories based on the ALBI score as follows; grade I:ALBI ≤-2.60, grade II:-2.60ALBI≤-1.39, and grade III:ALBI-1.39.A total of 273 patients, [180 (65.9%) men and 93 (34.1%) women], were evaluated. The median age was 60 years. ALBI grade was I in 45 (16.4%) patients, II in 156 (57.1%) patients, and III in 72 (26.5%) patients. Based on the ALBI grade, median progression-free survival (mPFS) was 9 months in grade I patients, 6 months in grade II patients, and 4 months in grade III patients (p=0.002), with median overall survival (mOS) durations of 12 months vs. 8 months vs. 5 months, respectively (p0.001). Multivariate analysis showed that ALBI grade II (HR,1.543) or III (HR,2.260) negatively affected survival.A higher pretreatment ALBI grade is related to worse OS and PFS in PC patients with liver metastasis treated with a first-line CT, and therefore it can help predict the treatment outcomes in these patients.

Several platelet indices have been linked to prognosis of various cancers, including metastatic colorectal cancer. The aim of this study was to investigate the prognostic effect of mean platelet volume (MPV) and platelet distribution width (PDW) in early colon cancer (CC) patients.This retrospective study included early CC patients who were followed up and treated between 2005 and 2017. Relapse free survival (RFS) and overall survival (OS) were determined with respect to several demographic and clinical characteristics of patients, including MPV and PDW. The cut-off value was determined as8.5 fL for MPV (sensitivity: 67.1%, specificity 54.5%) and ≤16% for PDW (sensitivity: 66.7%, specificity: 60.0%).The study included 394 patients, 53.3% of which were male. Stage I, II, and III patients constituted 8.9%, 46.4%, and 44.7% of the study population, respectively. Among all patients, RFS and OS were significantly longer in patients with MPV≤8.5 fL and PDW16 fL (p0.001 and p=0.011 for MPV, respectively; and p0.001 and p=0.026 for PDW, respectively). In patients with stage III disease, those with MPV≤8.5 fL had significantly longer RFS and OS compared to those with MPV8.5 fL (p0.001 and p=0.001, respectively). On the other hand, those with PDW16% had significantly longer RFS than that in those with PDW ≤16 fL among stage III patients (p0.001). In multivariate analysis, stage, perineural invasion, lymphovascular invasion, adjuvant treatment, CEA, CA19-9, PDW, and MPV were found the most significant factors affecting RFS.Our study suggests that elevated MPV and decreased PDW appear to be unfavorable prognostic factors in early CC, especially in patients with stage III disease. Considering the wide availability and accessibility of these indices, it is reasonable to designate further larger prospective studies to clarify and verify their potential roles in early CC.

Background:Body mass index (BMI) is defined as a poor prognostic factor in patients with breast cancer(BC). However, there are controversial results regarding the various effects of BMI on BC, hence the exactpathophysiology of the relation between obesity and BC is still under debate, and remains unclear. Thispaper aims to investigate the association between BMI at presentation and BC subtypes defined accordingto the immunohistochemical classification in both premenopausal and postmenopausal patients with BC.Patients and methods:This study is a retrospective and explorative analysis of the 3767 female BC pa-tients from a single center. All patients' BMI at the time of initial diagnosis and tumor demographics wererecorded. BMI was stratified into 3 groups as normal-weighted (BMI

To investigate the effects of sidedness on survival and treatment outcomes in patients with metastatic colorectal cancer (mCRC), since the accumulated data have increasingly reported that patient with right-sided mCRC are found to be associated with worse overall survival (OS) and poor response to anti-epidermal growth factor receptor (anti-EGFR) agents.This was a multi-center retrospective analysis of 177 patients with mCRC, who were treated and followed between 2014 and 2018 in different parts of Turkey. Patients were divided into 2 groups according to the primary tumor localization as right or left colon cancer. Clinical and demographic characteristics, treatment outcomes, and survival were analyzed to determine whether there was any association with tumor localization.There were 53 (30%) patients with mCRC in the right group and 124 (70%) in the left group, with no difference between the groups in terms of clinical and demographic characteristics. There was no difference in OS between the left and right side localization in any RAS-mutant mCRC patients (22.1 vs. 27.9 months, respectively, p=0.19), whereas patients with all RAS-wild type tumor in the right colon were associated with a worse OS than left-sided counterparts (19.4 vs 29.9 months, respectively, p=0.01). Multivariate analysis revealed that the right-sided tumor (HR, 1.74; 95% CI: 1.165-2.608; p=0.007), the presence of comorbid disease (HR, 1.58; 95% CI: 1.079-2.321, p=0.019), body mass index (BMI)25 ( HR, 1.61; 95% CI: 1.108-2.352, p=0.013), grade III tumor (HR, 1.65; 95% CI: 1.109-2.457, p=0.014), and being unable to metastasectomy (HR, 2.10; 95% CI: 1.235-3582, p=0.006) were found to be independent predictors of worse survival.While right side localization was an independent negative predictor of survival in patients with mCRC, tumor sidedness was not found to be associated with response to treatment. The worse OS in right localization may be due to the aggressive nature of right-sided colon tumors which show faster progression, since their response to treatment does not appear to be different.

Introduction: The relation between Behçet's disease (BD) and breast cancer (BC) is unclear. Our purpose is to investigate whether BD has an important effect on BC or vice versa. Patients and Methods: A total of 12 female BC patients with a diagnosis of BD were identified from a cohort including 5050 BC patients. The demographic data of the selected patients including previous chemotherapy (CT), radiotherapy (RT), hormonal therapy (HT), drugs used for BD, history of thrombotic events, and overall survival were examined. Results: The rate of BD in the entire cohort was found to be 0.25% (12/4800), and all had early BC at the time of BC diagnosis, with a median age of 47 years (range: 38–51). All patients underwent curative surgery for BC. In the adjuvant setting, CT, RT, and HT were administered in 11 (91%), 10 (83.4%), and 9 (75%) patients, respectively. All patients received acetylsalicylic acid and colchicine for BD. No serious adverse event associated with BC and/or BD was observed. Clinical symptoms in 11 patients with BD were observed to be improved following the BC treatment. Only one patient developed disease progression and then expired. Conclusion: Unlike the natural behavior of BD, which is well-defined to have an increased risk of thrombosis, BC patients with BD in this study did not have any adverse event. However, due to small sample size, it is difficult to drive any definite conclusion regarding the relation between these two pathologies.

It is well-known that tumor phenotype may change during the progression of breast cancer (BC). The purpose in this study was to compare the discordance in estrogen receptor (ER), progesterone receptor (PgR) and human epidermal growth factor receptor 2 (HER2) between primary and recurrent/metastatic lesions (RML) and also to evaluate the prognostic significance of change in tumor phenotype on survival in patients with metastatic BC.The medical records of 6638 patients with BC from two breast centers treated between 1992 and 2015 were retrospectively analyzed. Of the 6638 patients, 549 cases in whom recurrence was histologically proven by biopsy or by surgical resection were enrolled into this study.Our presentation 13.5% of the patients had metastatic disease. Biopsy on recurrence was obtained from distant metastasis sites in 250 (63.6%) patients or from locoregional soft tissues/lymph-nodes in 143 (36.4%). Receptor discordance in ER, PgR and HER2 expressions between primary and RML were 27.2% (p=0.32), 38.6% (p0.001) and 14.4% (p=0.007), respectively. Subsequent gain of ER and PgR showed significantly higher overall survival (OS) and post-recurrence survival (PRS) compared to the corresponding concordant-negative patients (119 vs 57 months, p=0.001 and 56 vs 31 months, p=0.03 for ER, 148 vs 58 months, p=0.003 and 64 vs 31 months, p=0.01 for PgR, respectively), hormone receptor (HR) loss was associated with worse OS. Similarly, HER2-loss cases experienced poorer PRS and OS outcomes, compared with those having stable HER2 expression (median 26 vs 60 months, p=0.009 for PRS and median 60 vs 111 months, p=0.06 for OS, respectively).This study confirmed the receptor discordance in ER/PgR and HER2 receptor expressions between primary and RML in patients with metastatic BC. As the loss of receptor expression is the most responsible factor for the discordance, treatments of recurrent/metastatic tumors should be individualized on the basis of molecular and genomic properties.

HER2-amplified breast cancer (BC) has a poor prognosis. The combination of trastuzumab with chemotherapy in the adjuvant setting decreases recurrence and improves overall survival in HER2-positive BC. However, the role of adjuvant treatment in patients with HER2-amplified small BC without lymph node involvement is still under debate. The purpose of this study was to investigate the safety of adjuvant paclitaxel and trastuzumab (APT) in this group of patients.A total of 87 operated early BC patients without lymph node involvement (N0) were treated with APT for 12 weeks followed by trastuzumab alone for a total of 9 months. Clinicopathological features and adverse events were analyzed.The median patient age was 50 years (range 28- 82), and 51% of them were postmenopausal. The median tumor diameter was 2.4 cm (range 0.5-6), with 51% of the patients having tumor size between 2 and 3 cm. Eighty-one percent of patients had invasive ductal carcinoma (IDC), and 64% had grade 3 tumors. Adjuvant hormone therapy and adjuvant radiotherapy were administered to 65 and 54% of patients, respectively. At a median follow up of 13 months (range 6-38), one patient (1.1%, 95% CI 0-3.4) experienced an asymptomatic decrease in left ventricular ejection fraction (LVEF) and 3 patients (3.4%, 95% CI 0-6.9) experienced grade 3 neuropathy.APT appears to be a safe combination in early-stage, HER2-amplified and node-negative BC.

The aim of this study is to measure and compare the dynamic thiol and disulphide homeostasis between patients with Uterine Myoma (UM) and healthy subjects.A total of 54 patients with UM who were diagnosed by transvaginal ultrasonography and 37 age- and body mass index-matched healthy individuals were included in this study. Thiol/disulphide homeostasis was measured by a novel automatic spectrophotometric method.The mean serum native thiol, disulphide, and thiol levels were statistically lower in UM group than those in the control group [(284.66±59.41μmol/L vs. 320.98±56.17μmol/L, P0.0001), (17.27±5.59μmol/L vs. 22.38±6.93μmol/L, P0.0001) and (319.21±61.69 vs. 365.76±61.46μmol/L, P0.0001), respectively]. There were no statistically significant differences in ratios of the disulphide/native thiol, native thiol/total thiol, and disulphide/total thiol among patients with UM versus healthy control group (P=0.096, 0.092, 0.092, respectively).It was found that the native thiol, total thiol, and disulphide levels in patients with UM decreased while the ratio of native thiol/disulphide remained unchanged.It is necessary to investigate whether these findings have a role in the etiology and clinical course of the UM.

Development of metastasis in patients with breast cancer (BC) is the most important negative prognostic factor and this process mainly begins with lymphatic involvement. Therefore, axillary, subclavicular, internal mammary or supraclavicular nodal involvement is a crucial step before metastasis. Anatomical differences between the right and left lymphatic drainages of the breasts may significantly affect the rate, site and time to development of distant metastasis. The purpose of this study was to investigate if laterality is an independent prognostic factor for metastasis in N3 breast cancer patients.From a total of 4215 BC patients diagnosed between 1994 and 2015 in our center, 305 non-metastatic women with pathological N3 (pN3) nodal status at presentation were enrolled in this study. Patients were divided into two groups: left and right BC. Analysis of overall survival (OS) and time to first metastasis (TTM) was performed according to Kaplan-Meier method with log-rank test.The median number of lymph node involvement and lymph node ratio (number of positive lymph nodes / total number of excised lymph nodes) between the two groups was equal (14 and 0,66 respectively). Recurrence was observed in 123 patients [53 (35%) right vs 70 (44%) left group]. Patients with left BC had significantly higher rate of axial bone metastases compared with the right BC group (55.7 vs 35.8%, p0.02, respectively). TTM was significantly shorter in the left BC group [49.1 months (95% CI 36.5-61.8) vs 103.6 months (95% CI 47.0-160); p7equals;0.03, respectively]. Median OS did not differ between the groups, however, there was a trend towards lower OS in patients with left BC (p=0.68).Left laterality in patients with pN3 non-metastatic BC is an independent prognostic factor associated with shorter TTM, increased risk of distant metastases and axial bone involvement compared with right laterality.

Poor sleep quality (SQ) is increasingly recognized as giving rise to decreased quality of life, and raising pain perception. Our aim is to evaluate the SQ in rheumatoid arthritis (RA) patients treated with anti-tumor necrosis factor alpha (anti-TNF-α) therapy. This was a prospective observational and open-label study of RA patients. A total of 35 patients with RA were enrolled in this study. Of the 35 patients, 22 had high disease activity (DA), and 13 were in remission. High DA group was initiated an anti TNF-α therapy. Clinical and objective parameters of SQ were assessed by using the Pittsburgh Sleep Quality Index (PSQI) and polysomnography (PSG). The total PSQI score and the frequency of poor SQ were high in 60 % of the RA patients. The median PSQI score was significantly higher in the high DA group than in the remission group (P = 0.026). Following an anti-TNF-α therapy initiation, significant improvements were observed in the high DA group by PSQI test (P = 0.012). However, no statistically significant difference was found by PSG (P > 0.05). Although an improvement in DA with anti-TNF-alpha therapy did not provide an amelioration in laboratory parameters, we found a significant improvement in SQ by subjective PSQI test. These findings may support that sleep disorders in RA are likely to be associated with a complex pathophysiology.

Invasive pleomorphic lobular carcinoma (IPLC) is defined to be an uncommon and different subtype of classical invasive lobular carcinoma (ILC). This special variant is characterized by significant cytological atypia and pleomorphism which differs from the cytological uniformity of ILC. IPLC has been shown to have some poor prognostic factors such as axillary node metastasis and higher histological grade which may lead to poor clinical courses including a short relapse time, increased risk of recurrence and a decreased survival. The aim of this study is to investigate the clinicopathological characteristics and prognosis of IPLC in comparison with ILC and also to evaluate if IPLC is a different clinical entity compared to ILC. A total number of 4418 breast cancer patients treated between 1996 and 2015 in Hacettepe University Cancer Institute, were retrospectively analyzed. Among 4418 patients, 210 were diagnosed with ILC and 23 patients diagnosed with pure IPLC. In this present study, clinicopathological characteristics, disease free survival (DFS) and overall survival (OS) of patients with ILC and IPLC were compared. This study design is one of the rare face to face comparison of pure IPLC and ILC. Patients with IPLC had an increased rate of higher histologic grade, extracapsular extension, lymphovascular invasion and lower percentage of hormone positivity than those of patients with ILC. During the follow-up time, IPLC group experienced 4 cases (17.3%) of recurrence, 5 cases (21.7%) of death and 2 cases (8.7%) of progression in 3 metastatic patients compared to that of 27 cases (12.9%) of recurrence, 29 cases (13,8%) of death and 14 cases (6.7%) of progression in 19 metastatic patients in the ILC group. Patients with IPLC had a worse DFS and OS duration than patients with ILC (P = 0.02 for OS, P = 0.04 for DFS). In conclusion, IPLC is a different and a special breast cancer subtype. This study suggests that IPLC is a distinct clinical entity with an advanced stage and more aggressive clinical course. Patients with IPLC reveal poorer prognostic factors such as higher histological grade, relative lower percentages of hormone positivity, and increased rate of recurrences resulting in poor clinical outcomes and worse survival. Nowadays, it is observed that current treatment methods for IPLC do not seem as successful as in ILC and failed to be effective. Thence, individual therapies including more aggressive surgery and adjuvant or neoadjuvant chemotherapy even in the earlier stages of breast cancer should be performed for this distinct variant.
