Background: Cancer patients frequently visit the emergency department (ED) with various symptoms of cancer. The purpose of this study was to determine the clinical characteristics and 1-year survival rate of cancer patients in the ED of a university hospital., Methods: We conducted a retrospective review of 408 cancer patients who visited the ED between January 2011 and December 2011. Patient information on demographics, chief complaints, findings, and survival was gathered from the hospital registry and corresponding health administration., Results: The study included 240 (58.8%) males and 168 (41.2%) females with a median age of 57.9 years (range 19-87). Regarding cancer staging, 266 patients (65.3%) had metastatic disease and 142 (34.7%) had local and loco-regional disease. The hospitalization rate was 59.6%. The most common symptoms were shortness of breath (23.2%), pain (17.8%), fever (14.2%), and nausea/vomiting (14.4%). The most common cancer sites were the lung (32.5%), gastrointestinal system (25.4%), and breast (9.3%). The initial evaluation determined progressive disease (42.4%), chemotherapy effects (20.7%), infections (17.2%), radiotherapy effects (4.7%), extravasation (1.8%), anemia (1.4%), and unknown (11.3%). During follow up, 191 (46.8%) patients died after admission to the ED. The 1-year overall survival of all patients was 7.3 months., Conclusions: Symptom management in cancer patients is a complex multifaceted concern for the emergency physician. Because of the increasing prevalence of cancer patients, emergency physicians should develop consensus algorithms in collaboration with the relevant disciplines to manage the commonly encountered problems.

Background: The aim of this study was to assess the epidemiological and clinicopathological characteristics of primary extranodal non-Hodgkin's lymphoma (pENL) patients, focusing on treatment and survival outcome., Materials and Methods: Between October 2003 and March 2012, 802 patients with non-Hodgkin's lymphoma (NHL) were diagnosed and treated in two different cancer centers of Southern Turkey., Results: pENL, constituted 12.4% (100/802) of all NHL studied during this period. Median age of the patients was 56 years (range 17-87 years) and the male: female distribution was 3:2. Eighty-five of 100 patients (85%) were in stage I/II, 9/100 (9%) in stage III, whereas 6/100 (6%) were in stage IV. Head and neck constituted the most common site (51/100, 51%), followed by gastrointestinal tract (GIL) (37/100, 37%), and cerebrum (CL) (5/100, 5%). Diffuse large B cell lymphoma (DLBCL) was the most common histological type, observed in 53% of patients, followed by marginal zone extranodal lymphoma (13%). Most of patients (76%) received a CHOP containing regimen. Complete remission (CR) were achieved in 71% of patients. The median follow-up duration of all patients was reported as 37.6 months (range, 0.8-165 months). This period was reported as 137.5 months (range, 117.5- 1578.6 months) in gastrointestinal lymphoma (GIL) patients, 119.0 months (range, 91.8-146.1 months) in head and neck lymphoma (HNL) patients, and 18.4 months (range, 12.6-24.1 months) in cerebral lymphoma (CL) patients., Conclusions: Head and neck, and the gastrointestinal tract were the two most common extranodal sites observed. Histologically DLBC accounted for the majority of cases. Most patients were on earlier stages, had low-low intermediate IPI scores and had a favorable prognosis.

Background: Astrocytic tumors, the most common primary glial tumors of the central nervous system, are classified from low to high grade according to the degree of anaplasia and presence of necrosis. Despite advances in therapeutic management of high grade astrocytic tumors, prognosis remains poor. In the present study, the frequency and prognostic significance of c-erb-B2 in astrocytic tumors was investigated., Materials and Methods: Records of 72 patients with low- and high-grade astrocytic tumors were evaluated. The expression of C-erbB-2 was determined immunohistochemically and intensity was recorded as 0 to 3+. Tumors with weak staining (1+) or no staining (0) were considered Her-2 negative, while tumors with moderate (2+) and strong (3+) staining were considered Her-2 positive., Results: Of the 72 patients, 41 (56.9%) had glioblastoma (GBM), 10 (13.9%) had diffuse astrocytoma, 15 (20.8%) had anaplastic astrocytoma, 6 (8.3%) had pilocytic astrocytoma. C-erbB-2 overexpression was detected in the tumor specimens of 17 patients (23.6%). Six (8.3%) tumors, all GBMs, exhibited strong staining, 2 (2.7%) specimens, both GBMs, exhibited moderate staining, and 9 specimens, 5 of them GBMs (12.5%), exhibited weak staining. No staining was observed in diffuse astrocytoma and pilocytic astrocytoma specimens. Median overall survival of patients with C-erbB-2 negative and C-erbB-2 positive tumors were 30 months (95%CI: 22.5-37.4 months) and 16.9 months (95%CI: 4.3-29.5 months), respectively (p=0.244)., Conclusions: Although there was no difference in survival, C-erbB-2 overexpression was observed only in the GBM subtype.

Purpose: Breast cancer incidence increases in the elderly but data on treatment and outcomes of elderly patients is limited. We assessed the clinicopathological features and outcomes of our patients with breast cancer aged ≥80 years in comparison with their younger postmenopausal counterparts., Methods: The records of 83 patients diagnosed with breast cancer after the age of 80 (group 1) between 2003 and 2011 in 4 different centers were retrospectively evaluated and the clinicopathological features and outcomes were assessed in comparison with a control group (group 2) of 249 patients aged between 60-70 years., Results: Median ages at diagnosis were 82 years (range 80-95) and 64 years (range 60-70) for group 1 and group 2, respectively. The incidence of invasive cancers other than ductal or lobular type was higher in group 1 than in group 2 (20 vs 8%; p=0.0177rpar;. More patients in group 1 had Charlson Comorbidty scores ≥1 than those in group 2 (49 vs 36%; p=0.011). Patients in group 1 had more conservative operations and less axillary node dissections (ALND) and they received chemotherapy, trastuzumab or radiotherapy less frequently compared to their younger counterparts in group 2. Median follow up period was 36 months (range 1-178) in group 1 and 24 months (range 12-217) in group 2. Five-year disease free survival (DFS) was 53.7 and 75.9) (p=0.005), 5-year overall survival (OS) was 61.9% and 80.47percnt; in group 1 and group 2 (p=0.001), respectively. Advanced stage (stage IV vs stage I, II, III, p=0.051) and cerbB2 positivity (p<0.001) were found to be associated with shorter DFS in patients ≥80 years of age., Conclusion: Although the majority of patients were undertreated in our study according to the current guidelines, mortality rates were quite low. Different biology of the disease in the elderly might explain this difference.

Purpose: Treating cancer often involves the use of chemotherapeutic agents. Due to the growing incidence of cancer worldwide and the expanding number of treatment options, it is important to understand the risks of adverse events associated with these treatments. In this study, we monitored the occurrence of acute infusion reactions in an outpatient chemotherapy center from April 2011 to April 2012., Methods: For patients who developed infusion reactions, the causative drug, the dose and number of treatments received, the onset time of the reaction, the duration of the reaction, blood pressure, pulse, level of oxygen saturation during the reaction, and other symptoms were recorded. The severity of reactions was determined in accordance with NCI toxicity criteria. A reaction was considered as grade 1-2 (mild-moderate) if the patient experienced flushing, rash, fever, tremor, dyspnea, rigor, and mild hypotension. Symptoms such as severe hypotension, bronchospasm, cardiac dysfunction and anaphylaxis, requiring therapeutic intervention, were classified as severe, grade 3-4 reactions., Results: Of the 2213 patients receiving chemotherapy during the study period, 138 (62%) developed an infusion reaction to the treatment. Among 138 patients most commonly treated types of carcinoma included breast (39.2%), lung (17.8%), colorectal (10%), and ovarian (8.5%) cancers. Docetaxel administration resulted in the largest number of infusion reactions, though most reactions were mild to moderate and did not require the cessation of treatment. Patients with mild to moderate reactions (89.2%) were able to continue treatment, while those who developed severe reactions (10.8%) could not continue treatment with the same agent., Conclusion: Although severe reactions are rare, the incidence of mild to moderate reactions against taxanes, platinum compounds, and monoclonal antibodies is quite high. Clinical symptoms do not vary widely among the agents, though the onset time of symptoms does vary. While reactions against platinum agents were of type 1 anaphylactic reactions, reactions against taxanes and monoclonal antibodies during the first infusion and in the following minutes suggest the activation of different mechanisms.

The relationship between thyroid disease and cancer (and cancer therapies) has been under investigation for years. Factors that increase the risk for thyroid disease include iodine deficiency, autoimmune disorders, old age, and pregnancy. The screening policy for thyroid disease in the healthy population is not precisely defined, and the frequency of thyroid dysfunction in untreated cancer patients has not been investigated in any great detail. This study was designed to compare the prevalence of thyroid dysfunction in 457 untreated cancer patients at the time of initial diagnosis to that of 373 age- and sex-matched subjects who were healthy and cancer-free (control group). Thyroid dysfunction was found in 29.5 % (135/457) of the cancer patients, while only 15.4 % (56/373) of the control group had thyroid dysfunction (p = 0.0001). The most prevalent abnormality was euthyroid sick syndrome (14.0 %, 64/457). Overt and subclinical hyperthyroidism and overt hypothyroidism were observed more frequently in cancer patients than the control group, and these differences were all statistically significant. Thyroid dysfunction was more frequent in patients with poor performance scores and those over the age of 50 years. These data indicate that alterations in thyroid hormone metabolism are twice as common in patients with untreated cancer than in control subjects. Those alterations may lead to delayed diagnosis, suboptimal treatment, and a poorer prognosis. In all, this study suggests that screening with thyroid function tests is strongly recommended in all newly diagnosed cancer patients.

Purpose: Patients with advanced cholangiocarcinoma present with high rate of local complications. The primary aim of this study is to report clinical course of advanced cholangiocarcinoma patients those who were presented with biliary obstruction and treated with percutaneous biliary stenting., Material and Methods: Patients with unresectable locally advanced or metastatic cholangiocarcinoma followed by our center for a period of 4 years were analyzed. For statistical analysis demographic and clinical characteristics of patients, primary biliary drainage method, metal stent occlusion rate, time to stent occlusion, and overall survival rates were recorded., Results: A total of 34 eligible patients were analyzed. 27 patients had metal stent placement. These 27 patients formed the basis of this study. Median overall survival (OS) was 6.0 months. After metal stent deployment bilurubin levels were normalized within a mean of 10 days. During the follow-up period, 13 patients were experienced metal stent occlusion. Median TtSO was 10 weeks. Cytotoxic chemotherapy was administered to 14 (52%) patients. Patients without stent dysfunction had significantly higher rate of chemotherapy exposure rate (p=0.021). Statistical analysis, however, failed to exhibit significant effect of stent dysfunction on OS., Conclusion: In advanced cholangiocarcinoma, relief of bile duct obstruction is an important part of the initial patient management. This study therefore described the clinical value of percutaneous metal stent in cholangiocarcinoma patients and raises the question about patency of metal stent in cholangiocarcinoma whether we can expect success similar to the success achieved in pancreas carcinoma., (Copyright © 2011 Elsevier Ireland Ltd.

Background: The majority of patients with head and neck cancer are treated with concurrent chemoradiotherapy. However, toxicity is substantial so that alternate schedules of cisplatin have been tried to overcome this problem. No formal comparison, however, has been reported between alternate schedules and reference regimen., Patients and Methods: Fifty-five eligible patients treated with concurrent chemoradiotherapy were retrospectively analyzed. The patients treated with weekly cisplatin were defined as group A, while the patients treated with standard regimen were defined as group B. Basic demographics and clinical characteristics', overall survival rate, locoregional or systemic relapse rates, and time to local/systemic relapse were recorded., Results: One, two, and three-year probability of survival in groups A and B were 75% to 65% after one year, 63% to 56%after two, and 63% to 52% after three, respectively. Although time to local and systemic relapse was higher in group B as compared to group A, a statistical analysis was failed to show any significant difference. Furthermore, there was no significant difference between groups with respect to major toxicity., Conclusion: In patients with head and neck cancer, concurrent chemoradiotherapy with weekly cisplatin might be as effective as concurrent chemoradiotherapy with bolus cisplatin.

Introduction: A 51-year-old female was admitted to emergency unit with sudden loss of consciousness. Her blood glucose level from fingertip was 33 mg/dl, and insulin level was 55 (normal range, 4-17 IU). Abdominal ultrasonography revealed pancreatic mass with diffuse liver metastases. Biopsy of liver metastases showed differentiated neuroendocrine carcinoma., Methods and Results: Diazoxide and chemotherapy stabilized her glucose level for more than 4 months. However, the disease showed progression, and death occurred 8 months later., Conclusion: In conclusion, this case may suggest that biologic behavior may differ from histological behavior in insulinoma and platin-based systemic chemotherapy may provide some benefit in patients those who had diazoxide- and octreotide-resistant tumors.

Primary signet-ring cell carcinoma of the colon is rare. Most patients with this type of cancer have a poor prognosis. We describe a patient with signet-ring cell carcinoma of the colon, for whom leptomeningeal metastasis presented a variety of clinical symptoms., (Copyright 2009 Elsevier Ltd. All rights reserved.)

Background: Hand-foot syndrome (HFS), the most common toxicity of capecitabine, is characterized by tingling, numbness, pain, erythema, dryness, rash, swelling, increased pigmentation, and/or pruritus of the palmar and/or plantar surfaces of the hands and/or feet. HFS is usually seen in both the hands and the feet, with varying severity. We have previously published a case report of dihydropyrimidine dehydrogenase (DPD) deficiency that manifested a variant of HFS., Case Report: We report the case of a 65-year-old Turkish Cypriot male patient with advanced gastric cancer who developed pain, numbness, and reddening in his left palm and left sole 10 days after the fourth cycle of capecitabine at a dose of 1,000 mg/m(2)/day twice daily (BID) on days 1 to 14 every 21 days. On physical examination, he had unilaterally erythematous changes and skin scaling on his left sole and palm consistent with grade II HFS. After stopping administration of capecitabine and supportive management, the HFS resolved in a week's time., Conclusions: To the best of our knowledge, this is the first case of capecitabine-induced unilateral HFS. Further investigation related to this toxicity associated with capecitabine is warranted.

Objective: Non-small cell lung cancer is a disease that affects the elderly. However, most patients older than 70 years are less likely to receive standard therapy than their younger counterparts and the aim of the present study was to determine age-dependent variation in efficacy., Subjects and Methods: Between 2004-2008, 40 consecutive patients older than 70 years received treatment for advanced non-small cell lung cancer. All were evaluated for response and toxicity. Chemotherapy was either with cisplatin or carboplatin and double or single agents (vinorelbine, gemcitabine). Docetaxel was used as a second line therapy in selected cases. Patients were grouped according to age: group 1 (70-74 years), group 2 (>or= 75 years)., Results: Except for 4 cases, all received chemotherapy, and 61 % were given a cisplatin-containing regimen. Second-line therapy was given to 42.5% and grades 3-4 neutropenia was seen in 17 (42.5%). Only one patient died due to neutropenic fever. Nephrotoxicity was observed in 2 (5%) and one underwent hemodialysis. Overall survival was 10 months, with median survival periods for groups 1 and 2 of 13 and 10 months, respectively (p> 0.05). No differences were found regarding type of chemotherapy administered or adverse events between the 2 groups., Conclusion: Patients older than 75 years appear to deserve the same standard therapy for non-small cell lung cancer as that given to younger cases.

Introduction: The prognostic value of HER2 expression in patients with advanced non-small cell lung cancer remains controversial. The relationship between HER2 expression, and platinum resistance and patient survival, was investigated., Methods: Seventy-three consecutive patients (median age, 61 years) with stage IIIB and IV non-small cell lung cancer, admitted between February 2004 and December 2006, were included in this study. Sixty-one patients received gemcitabine, given as two 1250 mg/m2 doses on days 1 and 8 and, cisplatin, given as a 75 mg/m2 dose on day 8. Twelve patients received vinorelbine, given as two 25 mg/m2 doses on day 1 and 8, and cisplatin, given as a 75 mg/m2 dose on day 1. Both treatment paradigms were repeated on a 21-day cycle. Tumor response was evaluated by comparing tumor size on computerized tomography scans before and after three cycles of chemotherapy. HER2 status was examined by immunohistochemical analysis of paraffin-embedded specimens., Results: HER2 was positive in 21 of 73 patients (28.8%). Of the 21 patients with HER2 positivity, 13 (61.9%) responded to chemotherapy with either a complete response, partial remission, or evidence of stable disease. Of 52 HER2-negative patients, 48 (92.3%) exhibited a response to chemotherapy. The difference in response to therapy between HER2-positive and -negative patients was statistically significant (p = 0.003). The median overall survival duration for all patients was 13 months. Median overall survival time was 14 months for HER2-negative patients and 10 months for HER2-positive patients (log-rank p = 0.007)., Conclusion: Non-small cell lung cancer patients with high expression of HER2 exhibited resistance to cisplatin-based chemotherapies that are the standard treatment for this disease. Our results indicate that HER2 status may be a predictive and prognostic factor for cisplatin- based therapy response and disease survival.

Background: The prognostic value of c-erbB-2 expression in patients with non-small cell lung cancer (NSCLC) remains controversial. The prevalence of c-erbB-2 expression in NSCLC and relation to disease prognosis were therefore investigated., Methods: Eighty-nine patients with NSCLC diagnosed at Baskent University, Adana Hospital, Medical Oncology Department, between 2000-2005 were investigated. Expression of c-erbB-2 was evaluated by immunohistochemistry in paraffin-embedded sections. Characteristics of patients, histology and stage of the disease were obtained from clinical records., Results: C-erbB-2 expression was detected in 18 patients (20.2%). Median survival of the patients with c-erbB-2 negative was 13 months, as compared to 6 months for c-erbB-2 positive cases (p=0.02), the relative risk of death being 1.96 times higher. No correlation was found between c-erbB-2 positivity and stage of the disease or histology of the tumor (p> 0.05)., Conclusions: C-erbB-2 positivity may indicate shorter survival and can be regarded as an unfavorable prognostic factor in NSCLC. Immunohistochemistry seems to be a readily applicable, inexpensive methodology for determining c-erbB-2 expression in NSCLCs.

Background: Although secondary renal involvement from systemic lymphoma is very frequent, primary renal lymphoma is a rare entity. It is characterized by aggressive histopathology, very early extra-renal infiltration and poor prognosis., Case Reports: Here, we report 4 cases of primary renal lymphoma presenting with unilateral renal masses, which after radiological and clinical examination were assumed to be renal cell carcinoma. 3 patients were diagnosed with Non-Hodgkin's lymphoma by nephrectomy and one patient was diagnosed by open renal biopsy. Histopathological subtypes were diffuse large B cell lymphoma in 2 cases and non-Hodgkin's lymphoma of small B cell type in the others. While 3 of the patients were treated with systemic chemotherapy, the fourth patient refused chemotherapy. 2 patients (no. 2 and 3) were still in complete remission and were followed regularly in the second and first year after diagnosis, respectively., Conclusions: Since it is difficult to diagnose primary renal lymphoma, most patients with this kind of tumor undergo radical nephrectomy, and diagnosis of primary renal lymphoma is delayed. The authors believe that both the delayed diagnosis due to anatomical difficulties and the histological aggressive characteristics of this disease are equally responsible for the poor outcome in the case of primary renal lymphoma., (Copyright 2009 S.

Aims and Background: Gemcitabine and cisplatin treatment were administered to patients with advanced-stage, non-small-cell lung cancer. During phase II studies, the treatment is performed using a 28-day cycle, with gemcitabine administered on days 1, 8, and 15. Although it is advised that cisplatin not be administered on the first day, gemcitabine and cisplatin treatment is usually performed using a 21-day cycle, with gemcitabine administered on days 1 and 8, and cisplatin is given on the first day in most phase III studies. In contrast with previous phase III studies, cisplatin was administered on day 8 in our study. Dose density, drug toxicity, and efficacy were analyzed., Methods and Study Design: Chemonaive patients with stage IIIB or stage IV nonsmall-cell lung cancer received gemcitabine (1250 mg/m2) on days 1 and 8 plus cisplatin (75 mg/m2) on day 8 every 3 weeks (1 cycle contained 2 applications)., Results: Sixty-seven patients received a total of 293 applications. Dose densities were 92.3% for gemcitabine and 93.9% for cisplatin. The types and rates of grade 3 and grade 4 hematologic toxicities were anemia (6%), granulocytopenia (46%), and thrombocytopenia (6%). Complete remission was seen in 2 patients (3%); partial remission was 40%, stable disease was 39%, and progression of disease, 10%. The median overall survival time was 13 months. The median progression-free survival time was 9.5 months. One-year survival rate was 54% and 2-year survival, 10.4%., Conclusions: In this 21-day treatment regimen, overall survival was longer than 1 year and the 1-year survival rate was more than 50%. Both the severity and rate of observed thrombocytopenia in the study were very low. Other adverse effects in the current study were comparable to those reported in the literature.

Gallbladder cancers are recognised common tumours of the gastrointestinal system. Histologically, almost all of them are adenocarcinomas. Previously, only two cases of signet-ring cell carcinoma of the gallbladder have been published, and little is known about the disease. Here, we present the case of a 76-year-old man with signet cell carcinoma of the gallbladder. Despite radical surgery, followed by 5-fluorouracil infusion chemotherapy, our patient died within 3 months. Advanced information may help to improve the prognosis of this tumour.

Recent studies suggest that cyclooxygenese-2 (COX-2) enzyme activation may play a role in hepatocarcinogenesis. However, the clinical significance of COX-2 expression in hepatocellular carcinoma (HCC) remains obscure. This study evaluated COX-2 expression in hepatitis B and hepatitis C virus related HCC and in HCC patients with an unknown etiology. Liver tissue samples of 31 patients with HCC (27 men and 4 women; age range, 48-75 years) were analyzed. COX-2 expression was evaluated by immunohistochemically in the tumor tissues. Patient data including age, sex, Child score, stage, grade of the tumor and survival were analyzed. Of these patients 19 were positive for hepatitis B virus (HBV), 6 were positive for hepatitis C virus (HCV) and 6 patients were negative for all viral markers and other etiologic factors. COX-2 staining were evaluated in 2 groups (group 1: COX-2 expression less than 25% (grades 1-2 COX-2 expression), and group 2: Cox-2 expression 25% or more (grades 3-5 COX-2 expression). COX-2 expression was shown in all HCC samples with positive or negative viral markers. No difference was found between degree of COX-2 expression and the etiology of HCC. COX-2 expression was not correlated with number of lesion or stage of the disease or grade of the tumor. COX-2 expression was not related with Child score of the patients. Median survival of all patients was 32 months. Median survival of patients did not differ according to patient's viral marker status. No difference was observed in median survival of patients in group 1 and 2. As a result, COX-2 system seem to be shared part in hepatocarcinogenesis regardless factors that initiate the disease. Although COX-2 expression appears to be independent of disease's characteristics', treatments that target this system appear to be feasible in the management of HCC.

Objectives: To report a rare case of small cell carcinoma of the prostate with unusual skin metastasis., Clinical Presentation and Interventions: A 60-year-old was evaluated for difficulty in urinating. Abdominal computed tomography scans revealed a prostatic mass invading the surrounding tissues and multiple perirectal, periprostatic, para-aortic and pericaval lymph nodes. Needle biopsy specimens showed both small cell carcinoma and adenocarcinoma. He was treated with combination chemotherapy: cisplatin and etoposide and bilateral orchiectomy. After six cycles of the chemotherapy, disease progressed and the patient did not respond to salvage therapy; hence, palliative care was instituted. During the follow-up, papillary lesions were observed in the scrotal skin; biopsy showed metastatic small cell carcinoma., Conclusion: Small cell carcinoma of the prostate is an aggressive disease with a highly metastatic potential; but skin metastases are very uncommon. It has poor prognosis despite therapy. Management resembles that of small cell carcinoma of the lung., ((c) 2008 S. Karger AG, Basel)

Papillary microcarcinoma (PMC) is a thyroid tumor measuring 10mm or less in maximum diameter and comprise up to 30% of all papillary thyroid cancers. Most of them are detected incidentally and defined as incidental papillary microcarcinoma (IPC

Cancer cachexia is a syndrome characterized with progressive weight loss and abnormal wasting of fat and muscle tissue, and affects 40 to 85% of all terminally ill patients, accounting more than 20% of all cancer deaths. Current treatment for cancer cachexia principally depends on its prevention rather than reversing the present disease state, and the clinical results are far from being satisfactory. Although the exact mechanism and predisposing factors have yet to be clarified in detail, our growing knowledge about the pathophysiology and biochemical changes considering this life threatening condition should help in development of future therapeutic strategies. In the present paper, the current preclinical and clinical features considering the pathophysiology and treatment of cancer related cachexia are reviewed.

Renal transplantation confers increased survival with improvement of immune suppressive drugs, but certain types of neoplasm can arise as secondary complications. It is thus well known that recipients have significantly increased risk of developing de novo malignancy when compared with the age-matched general population. Cancer is the 4th most common cause of death in transplant patients after cardiovascular disease, infections and liver failure. Our transplantation team has performed 1,582 kidney transplantations since 1975. Fifty-nine of the patients developed malignancies in the posttransplantation period. The most common was Kaposi's sarcoma (19 patients, 32.2 %), followed by lymphomas (16 patients, 27.1 %) and skin carcinomas (13 patients, 22.0 %). Many factors can contribute to high susceptibility in these patients; age at transplantation, certain types of viral infections like Epstein-Barr virus, human herpes virus-8, human papilloma virus or chronic usage of immune suppressive agents, type of immune suppressive drugs, and ethnic characteristics. Transplant recipients generally have advanced stage cancers at the time of diagnosis with a poor prognosis. Since some neoplasms are common early detection of cancer is important to decrease cancer related mortality and morbidity. This article considers risk factors and recommendations for early diagnosis of cancer in renal transplant patients.

Adenocarcinoma is the usual histological presentation of the very rare gallbladder carcinoma. Adenosquamous cell carcinoma accounts for less than 3.5% of gallbladder carcinomas, and is characterised by invasive growth, a reduced tendency for lymph node metastasis, an increased tendency for hepatic infiltration or liver metastasis, and a poorer prognosis than adenocarcinoma. We present two cases. The first patient presented to our institution with increased bilirubin levels and dilated intra- and extrahepatic bile ducts. Adenosquamous carcinoma of the gallbladder was diagnosed on the post-operative pathological specimen. After surgery, bilirubin levels decreased, but hepatic metastases occurred that did not respond to conventional chemotherapy. The second patient was admitted to our hospital with jaundice and abdominal pain. Abdominal computed tomography (CT) imaging showed marked thickening of the gallbladder with direct extension of a mass into the left liver lobe. Cytology specimens obtained with an endoscopic retrograde cholangiopancreatography (ERCP) procedure revealed a malignant epithelial tumour. The patient underwent surgery but the tumour was incompletely resected. A regimen of oral UFT (Tegafur + uracil) chemotherapy was begun. Serum bilirubin levels increased due to occlusion in the surgical area 15 weeks after the start of chemotherapy.

Squamous cell carcinoma (SCC) originating from the stomach is a relatively rare entity. There are theories regarding the development of this rare tumor, but its exact pathogenesis remains obscure. Fewer than 100 cases of primary SCC of the stomach have been presented in the literature. Due to the advanced stage at the time of diagnosis in most of these cases, the prognosis is generally poor. In the case presented here, dissemination of the tumor to the transverse colon, gallbladder and omentum was present at diagnosis. Despite the tumor's advanced stage, complete remission was achieved after six courses of adjuvant chemotherapy with 5-flourouracil and cisplatin. No recurrence has been detected during follow-up. The patient has been healthy with no sign of the disease for three years.

Malignant pleural effusions are rare in multiple myeloma (MM). We report a case of MM with left myelomatous pleural effusion, which reflects aggressive disease.

Chronic lymphocytic leukemia (CLL) is the most common type of leukemia worldwide. It is an indolent disease, almost exclusively of B-cell origin. Some CLLs evolve into a more aggressive lymphoid malignancy. The most common of these is Richter's syndrome. Transformation to acute lymphoblastic leukemia, plasma cell leukemia, multiple myeloma, or Hodgkin's disease (HD) may also occur. CLL patients are also at a significantly increased risk of developing a second malignant neoplasm later in life. One of the most common of these is HD. Herein, we report a case of HD in an elderly man with a history of B-cell CLL.

Immune thrombocytopenia of malignancy is most frequently associated with lymphoproliferative disorders. Thrombocytopenia generally does not develop in MALT subtype of lymphoma (MALTOMA) unless the tumor has infiltrated the bone marrow. Cytopenias resulting from immunologic causes in patients with MALT lymphoma were rarely reported in the literature. In this report, a woman was diagnosed with stage IIE gastrointestinal MALTOMA. Bone marrow infiltration was not present. Patient also had thrombocytopenia, which did not improve after intravenous steroid treatment. Thrombocyte count increased after a single gamma-globulin infusion, and 6 cycles of chemotherapy were given every 21 days. The patient has remained in complete remission.

The olive has a history almost as long as that of Western civilization and has been looked upon as a sign of hope, peace, and sacredness. Olive oil, extracted from the olive, is the principal source of dietary fat in the Mediterranean basin. The composition differs from that of other dietary fats in that olive oil is rich in monounsaturated fatty acids. Even other than as a source of monounsaturated fats, olive oil has own unique effects. Accumulating evidence suggests that olive oil may have beneficial health effects, especially when it comes to reducing risk factors for coronary heart diseases, preventing cancer, and modifying immune and inflammatory responses. However, evidence remains limited, definitive conclusions are difficult to draw, and there remains a significant need for further studies, particularly prospective cohort and well-designed, controlled intervention studies. In this manuscript, the beneficial health effects of olive oil are reviewed, with particular attention paid to cancer prevention and immune functions..

Background: Acute pulmonary toxicity in cancer patients treated with docetaxel has been reported in previous phase II studies and case reports. Unlike transient pulmonary infiltrates, it is demonstrated that docetaxel-induced interstitial pneumopathy is a severe clinical condition that generally leads to respiratory failure., Case Report: We report a patient with breast cancer who received 2 cycles of docetaxel in 3-week intervals and developed respiratory failure. The clinical, pathologic, and radiographic data supported pulmonary toxicity caused by a hypersensitivity reaction to docetaxel as the most likely etiology. The patient developed the same symptoms and radiological findings after 1 cycle of paclitaxel administration. Unlike other more severe examples in the literature, this patient's condition did not require mechanical ventilation, and she recovered after corticosteroid treatment., Conclusion: The present case raises the possibility that taxanes, as a group of chemotherapeutic agents, may cause the same type of adverse reaction in the pulmonary parenchyma. The authors recommend that any patient who develops a taxane-induced pulmonary toxic reaction, not be rechallenged or treated with another agent of the same class.

Background: Leukemia is a well-known complication of cancer therapy, but development of acute myeloid leukemia (AML) after renal transplantation is rare. Immunosuppressive therapy for organ transplant recipients is complicated by high rates of malignant disease, one condition being Kaposi's sarcoma (KS)., Case Report: A 22-year-old woman developed KS 1 year after renal transplantation, and then developed AML another 4 years later. When KS was diagnosed it was already in extensive stage, and she received ABV combination chemotherapy with doxorubicin plus bleomycin plus vincristine intravenously (i.v.) once daily every 2 weeks. She entered remission but the KS relapsed and 8 cycles of i.v. etoposide monotherapy were given and she re-entered remission. 19 months later, the patient was admitted to hospital with severe malaise, leukocytosis, thrombocytopenia, and anemia. The diagnosis was AML (FABM4). The patient received induction chemotherapy consisting of cytarabine and idarubicin. After completion of this induction therapy she developed neutropenic infection, dyspnea and confusion. Her condition deteriorated rapidly after that, and she died., Conclusion: KS is one of the most common malignancies in renal allograft recipients, whereas AML is a less frequent problem. To our knowledge, this is the first published case of these two different malignancies developing after renal transplantation. The pathogenesis of the AML is discussed., (Copyright 2004 S.

We present a 78-yr-old man with appendicular metastases from pancreatic adenocarcinoma. Barium enema X-ray showed incomplete filling of a distended appendix in a patient with abdominal discomfort. Colonoscopic evaluation revealed firm nodules in appendicular orifice. Histopathological examination of the nodule in the appendix revealed a metastatic adenocarcinoma. Abdominal computed tomography showed a low-density mass in the body of the pancreas. Endoscopic ultrasonography disclosed a hypoechoic mass in the body of the pancreas. Appendicular metastasis is extremely rare. To our knowledge, this is the second case of adenocarcinoma of the pancreas metastatic to the appendix in English language literature. A brief review of relevant literature is presented.

Hydroxyurea (HU) is an antitumor agent used to treat chronic myeloproliferative disorders. HU is usually well tolerated, but several cutaneous changes have been reported during long-term HU therapy. Although the occurrence of dermatomyositis-like changes during long-term HU therapy are well known, they are rarely described in patents with polycythemia vera. We report a 69 year-old-male with polycythemia vera who developed a dermatomyositis-like eruption on his face and dorsum of the hands following long-term HU therapy. Despite the cutaneous features, there were no clinical signs of muscular involvement, and muscle specific enzymes were within normal ranges. After interruption of HU administration, the skin lesions disappeared within two months. The improvement following withdrawal of HU implicated this drug as a possible etiological factor in the development of cutaneous features of dermatomyositis in our patient.

Background: Tumour markers along with other tests, may be useful in the assessment of the prognosis, monitoring response to treatment and early detection of metastases in breast cancer. The most commonly used breast cancer antigen is CA 15-3., Objective: To examine the value of CA 15-3, ceruloplasmin and tissue polypeptide specific antigen (TPS) panel in the monitoring of breast cancer., Subjects: Serum concentrations of CA 15-3, ceruloplasmin and TPS were measured in 90 women: Fifteen controls, sixteen patients with benign breast disease (BBD), thirty one patients in remission and twenty eight patients with active breast cancer., Results: The results of CA 15-3, ceruloplasmin and TPS estimates were separated into four groups. The patients not in remission were found to have significantly higher levels of CA 15-3 (p<0.0001) and ceruloplasmin (p<0.0001) compared with the other three groups. The difference between the patients in remission, BBD and the control group was not statistically significant (p>0.05) for CA 15-3 and ceruloplasmin. The difference for TPS between the patients in remission and the patients with active breast cancer was not statistically significant (p>0.05). The sensitivities of CA 15-3, ceruloplasmin, and TPS for detecting active breast cancer were 75.0%, 75.0%, and 78.0%, respectively., Conclusion: The highest sensitivity for active breast cancer detection was obtained by the combined use of three tumour markers. We concluded that there may be an advantage in using panels in the follow up of breast cancer patients, although so far such tests have too low a specificity to be of practical value in screening.

The treatment of infectious complications in cancer patients has evolved as a consequence of the developments in the chemotherapy of cancer patients. In this prospective, randomized study, we compared imipenem-cilastatin and sulbactam-cefoperazone with amikacin in the empiric therapy of febrile neutropenic (< 1000/mm3) patients with liquids and solid tumours. Of 30 evaluable episodes, 15 were treated with imipenem-cilastatin and 15 were treated with sulbactam-cefoperazone plus amikacin. 73% of episodes were culture-positive: gram-positive pathogens accounted for 62% of the isolates. Bacteremia was the most frequent site of infection. The initial clinical response rate for both regimens was 60% (p > 0.05). No major adverse effects occurred. This study demonstrated that imipenem-cilastatin monotherapy and combination therapy of sulbactam-cefoperazone plus amikacin were equally effective empiric therapy for febrile granulocytopenic cancer patients.

Despite intensive search for the optimal combination chemotherapy for aggressive non-Hodgkin's lymphoma (NHL), the CHOP (cyclophosphamide, adriamycin, vincristine and prednisolone) regimen is still the standard therapy. We investigated the clinical efficacy of a new combination regimen consisting of vincristine, bleomycin-cyclophosphamide, adriamycin, etoposide and prednisolone (VB-CHEP) in patients with aggressive NHL. A total of 29 patients with aggressive NHL was enrolled into the protocol. Eight patients were consolidated with cisplatin and cytarabine and 5 patients received radiotherapy for bulky disease. Objective response was achieved in 82.8% of the patients. Complete remission (CR) and partial remission rates were 72.4%, and 10.3%, respectively. CR rate was significantly lower in patients with advanced stage, extranodal disease and bone marrow involvement. Median follow-up time is 34+ months; 17 patients are disease-free while 12 died and only 2 patients with CR have relapsed so far. Median response duration is 29+ months and the median survival is 48+ months. The survival rate is 69% in the first year and 66% in the second year. A total of 152 cycles were evaluated for toxicity. Major hematological toxicity was myelosuppression and neutropenia, detected in 50.65%, was mostly grades 1-2. Neutropenic fever occurred in only 11 cycles. The side effects of the consolidation therapy were also acceptable. We conclude that the VB-CHEP regimen with consolidation therapy for high-risk patients may be an effective treatment for advanced stage aggressive NHL.

Aims and Background: Disorders of hemostasis in patients with malignancies are based on several mechanisms, such as ability of the tumor to alter the coagulation system by producing blood clotting factors or decreasing their inhibitors by increasing fibrinolysis, and by inducing an alteration of blood vessels in relation to the state of local invasion. We investigated the fibrinolytic system marker alpha2-antiplasmin-plasmin complex (APP) and clotting system marker thrombin-antithrombin III complex (TAT) in patients with breast cancer and compare them with CA 15-3, the most well-known breast cancer antigen., Methods: Plasma levels of APP and TAT and serum level of CA 15-3 were determined in 57 patients with breast cancer (28 in remission and 29 with active breast cancer) and 13 healthy women., Results: In patients with active breast cancer, plasma APP levels were significantly elevated compared to those of other groups (P<0.05). In addition, we observed a poor but positive correlation between plasma levels of APP and those of CA 15-3 (r=0.24; P=0.038). Plasma TAT levels, which reflect the activation of thrombin, were also significantly elevated in patients with active breast cancer (P<0.01), and there was a significant correlation between CA 15-3 and TAT (r=0.24; P=0.041)., Conclusions: We demonstrated that increased APP and TAT levels might reflect enhanced activation of coagulation and the fibrinolytic system in patients with active breast cancer.

Over the past years, quality of life (QOL) in patients with breast cancer has continued to be a noteworthy area of research. The diagnosis and management of cancer can have a major impact on every aspect of a patient's QOL. Sixteen women with breast cancer (during chemotherapy and 4 months after adjuvant chemotherapy) and 15 healthy women controls underwent 42-item QOL questionnaire in eight dimensions which assessed general well-being, physical symptoms and activity, sleep disturbance, appetite, sexual dysfunction, cognitive functions, medical interaction, social participation, and work performance. The subjects were asked to choose only one of five predefined constant options, which were scored from one to five in a Likert scale with multiple options, and total QOL scores were obtained. Although the total QOL score was not statistically different between the groups (p > 0.05), general well-being, physical symptoms and activity, and sleep disturbance showed significant regression in breast cancer patients compared to the controls (p < 0.05). Appetite (p < 0.02) and physical symptoms and activity (p < 0.05) significantly improved in the group after chemotherapy compared to the group during chemotherapy.
