RESUMEN
BACKGROUND: The optimal treatment for metastatic colorectal cancer (mCRC) after the second line is still controversial. Regorafenib has been the standard of care in this setting as it improved overall survival (OS) compared to placebo. In real-world practice chemotherapy rechallenge is also a preferred option even though supporting evidence is not enough. We aim to compare the efficacy of regorafenib and 5-fluorouracil-based (5-FU) rechallenge treatment in the third line setting of mCRC. METHODS: In this retrospective multi-institutional trial, mCRC patients from 21 oncology centers who progressed after 2 lines of chemotherapy were analyzed. Patients who were treated with regorafenib or rechallenge therapy in the third-line setting were eligible. Rechallenge chemotherapy was identified as the re-use of the 5-FU based regimen which was administered in one of the previous treatment lines. OS, disease control rate (DCR), progression free survival (PFS) and toxicity were analyzed. RESULTS: Three hundred ninety-four mCRC patients were included in the study. 128 (32.5%) were in the rechallenge, and 266 (67.5%) were in the regorafenib group. Median PFS was 5.82 months in rechallenge and 4 months in regorafenib arms (hazard ratio:1.45,95% CI, p = 0.167). DCR was higher in the rechallenge group than regorafenib (77% vs 49.5%, respectively, p = < 0.001). Median OS after the third-line treatment was 11.99 (95% CI, 9.49-14.49) and 8.08 months (95% CI, 6.88-9.29) for rechallenge and regorafenib groups, respectively (hazard ratio:1.51, 95% CI, p < 0.001). More adverse effects and discontinuation were seen with regorafenib treatment. CONCLUSION: Our study revealed that higher disease control and OS rates were achieved with rechallenge treatment compared to regorafenib, especially in patients who achieved disease control in one of the first two lines of therapy.

AIM: Description of patient characteristics, effectiveness and safety in Turkish patients treated with pazopanib for metastatic soft tissue sarcoma (STS). PATIENTS AND METHODS: This multicenter study is based on retrospective review of hospital medical records of patients (≥ 18 years) treated with pazopanib for non-adipocytic metastatic STS at 37 Oncology clinics across Turkey. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS) and overall survival (OS) were evaluated with further analysis of data on the three most common histological subtypes (leiomyosarcoma [LMS], undifferentiated pleomorphic sarcoma [UPS], synovial sarcoma [SS]) in the cohort. RESULTS: Data of 552 adults (57.6% women, median age: 52 years) were analyzed. DCR and ORR were 43.1% and 30.8%, respectively. Median PFS was 6.7 months and OS was 13.8 months. For LMS, UPS and SS, median PFSs were 6.1, 5.9 and 7.53 months and median OSs were 15.03, 12.87 and 12.27 months, respectively. ECOG ≥ 2 was associated with poor PFS and OS. Liver metastasis was only a factor for progression. Second-line use of pazopanib (vs. front-line) was associated with better PFS, its use beyond third line predicted worse OS. Adverse events (AE) occurred in 82.7% of patients. Most common AEs were fatigue (58.3%) and anorexia (52.3%) which were graded as ≥ 3 in 8.2% and 7.4% of patients, respectively. CONCLUSION: Pazopanib is effective and well-tolerated in treatment of non-adipocytic metastatic STS. Its earlier use (at second-line), good performance status may result in better outcomes. Worldwide scientific collaborations are important to gain knowledge on rarer STS subtypes by conducting studies in larger patient populations.

PURPOSE: Atezolizumab has been shown to be effective and safe in randomized trial in the first-line treatment of extensive-stage small cell lung cancer (SCLC). However, there are limited real-life data on atezolizumab. In this study, we aimed to determine the real-life efficacy and safety of atezolizumab combined with chemotherapy in the first-line treatment of extensive-stage SCLC. METHODS: This trial is a retrospective multicenter study of the Turkish Oncology Group, which included extensive-stage SCLC patients who received atezolizumab combined with chemotherapy in a first-line treatment. The characteristics of the patients, treatment and response rates, and PFS and OS are presented. Factors associated with PFS and OS were analyzed by univariate and multivariate analysis. RESULTS: A total of 213 patients at the 30 oncology centers were included. The median number of chemotherapy cycle was 5 (1-8) and atezolizumab cycle was 7 (1-32). After median 11.9 months of follow-up, median PFS and OS was 6.8 months (95%CI 5.7-7.8), and 11.9 months (95%CI 11-12.7), respectively. The ORR was 61.9%. ECOG-PS (p = 0.002) and number of metastatic sites (p = 0.001) were associated with PFS and pack-year of smoking (p = 0.05), while ECOG-PS (p = 0.03) and number of metastatic sites (p = 0.001) were associated with OS. Hematological side effects were common and toxicities were manageable. CONCLUSION: This real-life data confirm the efficacy and safety of atezolizumab in combination with chemotherapy in first-line treatment of extensive-stage SCLC.

PURPOSE: In this study, we aimed to investigate the utilization of 68Ga-FAPI PET/CT in comparison to 18FDG PET/CT to evaluate the peritoneal involvement of the gastrointestinal malignancies alongside primary lesions and other metastatic foci. PROCEDURES: A total of 37 patients with various gastrointestinal malignancies with accompanying peritoneal involvement who underwent 68Ga-FAPI PET/CT and 18FDG PET/CT imaging between September 2020 and June 2021 were included in this retrospective study. SUVmax values of 68Ga-FAPI and 18FDG were compared according to lesion locations. Also, the lesion localization ability of both imaging was compared in patient basis. RESULTS: Of the 37 patients with peritoneal involvement (23 males and 14 females; median age, 62.8 ± 12.7 years), 35.1% (n = 13) had colorectal cancer, 37.8% (n = 14) gastric cancer, and 27.0% (n = 10) pancreaticobiliary cancer. While 45.9% of them were operated, the remaining did not have surgery. The mean time interval between two studies was 3.2 days (range: 2-6 days). The mean SUVmax value of peritoneal metastases (p < 0.001) was significantly higher with 68Ga-FAPI PET/CT compared to that with 18FDG PET/CT, as in primary lesions (p < 0.001), lymph node metastases (p = 0.006), liver metastases (p = 0.002), and bone metastases (p = 0.018). A total of 185 lesions was detected in the initial assessment with 18FDG PET/CT. Of the total lesions detected with 18FDG PET/CT, 5 of them were evaluated as benign lesions with 68Ga-FAPI PET/CT also in accordance with the reference standard. In addition to 180 lesions detected with 18FDG PET/CT, a total of 37 additional malignant lesions, 12 of which were peritoneal metastases, were detected with 68Ga-FAPI PET/CT. CONCLUSION: 68Ga-FAPI PET/CT was determined to be superior to 18FDG PET/CT in terms of detection of peritoneal involvement with high image quality as well as primary tumor and other metastatic foci. Consequently, 68Ga-FAPI PET/CT can be used as a complementary imaging modality especially for inconclusive 18FDG findings due to the lack of accuracy of 18FDG PET/CT in some of the metastatic regions, especially in the liver.

PURPOSE: This study evaluated the efficacy and safety of everolimus (EVE) plus exemestane (EXE) in hormone-receptor positive (HR+), human epidermal growth factor receptor-2-negative (HER2-) metastatic breast cancer (MBC) patients in real-life settings. METHODS: Overall, 204 HR+, HER2- MBC patients treated with EVE + EXE after progressing following prior endocrine treatment were included. Overall survival (OS) and progression-free survival (PFS) and safety data were analyzed. RESULTS: The objective response rate, median PFS, and median OS were 33.4%, 8.9 months, and 23.4 months, respectively. Multivariate analysis revealed that negative progesterone receptor status was a significant determinant of poor treatment response (p = 0.035) and PFS (p = 0.024). The presence of bone-only metastasis was associated with better treatment response (p = 0.002), PFS (p < 0.001), and OS (p = 0.001). CONCLUSION: We confirmed the favorable efficacy and safety profile of EVE + EXE for HR+, HER - MBC patients.

PURPOSE: In the ToGA trial for HER2-positive advanced gastric cancer, cisplatin plus fluoropyrimidine was given for 6 cycles; trastuzumab was given until disease progression. However, there is a lack of real-life data about trastuzumab maintenance after 6 cycle chemotherapy. This study aims to present real-life data of trastuzumab ± capecitabine maintenance after 6 cycles of platinum, fluoropyrimidine, and trastuzumab in non-progressive patients. METHODS: This is a retrospective multicenter study of the Turkish Oncology Group. A total of 35 HER2-positive, inoperable locally advanced, recurrent, or metastatic gastric adenocarcinoma patients being non-progressive at the end of 6 cycle chemotherapy and being given trastuzumab ± capecitabine as maintenance treatment were included from sixteen oncology centers. Baseline characteristics, objective tumor responses, progression free and overall survival data, and toxicities were determined. RESULTS: About 68% of the patients were given CF, and 32% were given FOLFOX with trastuzumab as the first-line treatment. The best response in 6 cycle chemotherapy was complete 8 (22%), partial 24 (68%), and stable disease 3 (8%). All patients had trastuzumab maintenance (median cycle 13; range 7-51), and 49% of the patients had capecitabine with trastuzumab (median capecitabine cycle 6; range 2-30). The median PFS of the patients was 12.0 months (95% CI 10.3-13.7), and median OS was 17.4 months (95% CI 15.2-19.5). There were 2 patients with grade 1 cardiotoxicity. CONCLUSION: Trastuzumab maintenance ± capecitabine after 6 cycles of trastuzumab plus combined chemotherapy treatment revealed efficacy and safety in non-progressive HER2-positive advanced gastric cancer.

OBJECTIVE: The present study aims to evaluate the antioxidant effect of beta-glucan on oxidative DNA damage by comet assay. METHODS: A total of 19 adult females and males diagnosed with stage 3-4 colorectal cancer and a control group of 20 age-matched healthy subjects were enrolled in the study. Blood samples of the participants were analyzed using Comet Assay for the parameters of DNA damage. RESULTS: Significantly increased DNA damage was observed in patients versus the control group as indicated by greater values of tail moment, tail percent DNA and tail length. Following incubation with ß-glucan, a substantial reduction was found in the aforementioned parameters of DNA damage. Comet assay revealed significant levels of endogenous DNA damage in patients as shown by remarkable increases in the tail moment, the percentage of DNA in the tail and the tail length values, in comparison with the control group. Following treatment of fresh whole blood with ß-glucan incubation, DNA damages were significantly reduced, but lower values were observed after ß-glucan incubation in the patient group versus control group. CONCLUSION: ß-Glucan was found to reduce DNA damage substantially in colorectal cancer patients and show antimutagenic effects. Our results suggested that dietary ß-glucan intake might be important in the genesis of colorectal cancer tumors.

PURPOSE: We compared the ability of 68Ga-FAPI PET//CT with 18FDG PET/CT imaging techniques to detect additional lesions in breast cancer patients that may affect further chemotherapy options. METHODS: A total of 48 patients with breast cancer underwent concurrent 68Ga-FAPI-04 and 18FDG PET/CT regardless of whether they had received chemotherapy or not in the last month before imaging. Both modalities were compared according to various parameters: clinical/pathological features, number of lesions detected, activity uptake (SUVmax), and the effect on the evaluation of response to treatment in the post-chemotherapy group. RESULTS: This retrospective study included 48 patients with breast cancer (mean age 53.3 ± 11.7 years; IDC 89.6%; ILC 10.4%). In the comparison of both modalities, no statistical significance was obtained in terms of the pathological characteristics of the patients. More lesions were demonstrated in all categorized regions in 68Ga-FAPI PET/CT imaging with higher uptake values compared to 18FDG PET/CT in this study. In the treatment response evaluation of the post-chemotherapy group, 12 cases (12/24) who were evaluated as PMR, CMR, or SD according to 18FDG PET/CT results were later accepted as PD due to newly detected lesions in complementary 68Ga-FAPI PET/CT imaging and treatment of patients was managed accordingly by clinicians. CONCLUSION: It was determined that 68Ga-FAPI PET/CT was superior to 18FDG PET/CT in terms of accuracy and it was thought that 68Ga-FAPI PET/CT could be utilized as an additional complementary imaging to 18FDG PET/CT. Moreover, 68Ga-FAPI PET/CT, with its significant theranostic potential, could become a key element in predicting the pathological response of breast cancer patients in further researches.

AIM: The aim of this study is to evaluate the efficacy and toxicity of trastuzumab emtansine (T-DM1) in cases with metastatic breast cancer (mBC) in different lines of treatment. METHOD: Retrospective analysis of T-DM1 results of human epidermal growth factor receptor 2 (Her2) positive 414 cases with mBC from 31 centers in Turkey. FINDINGS: Except 2, all of the cases were female with a median age of 47. T-DM1 had been used as second-line therapy in 37.7% of the cases and the median number of T-DM1 cycles was 9. Progression-free survival (PFS) and overall survival (OS) times were different according to the line of treatment. The median OS was found as 43, 41, 46, 23 and 17 months for 1st, 2nd, 3rd, 4th and 5th line, respectively (p = 0.032) while the median PFS was found as 37, 12, 8, 8 and 8 months, respectively (p = 0.0001). Treatment was well tolerated by the patients. The most common grade 3-4 adverse effects were thrombocytopenia (2.7%) and increased serum gamma-glutamyl transferase (2%). DISCUSSION: The best of our knowledge this is the largest real-life experience about the safety and efficacy of T-DM1 use in cases with mBC after progression of Her2 targeted treatment. This study suggests and supports that T-DM1 is more effective in earlier lines of treatment and is a reliable option for mBC.

BACKGROUND: This study was conducted to collect clinical safety, tolerability, and efficacy data with the use of everolimus (EVE) combined with exemestane (EXE) in patients with advanced breast cancer (ABC). METHODS: The EVEREXES trial initiated in 2012, provided early access to the first dual blockade treatment with EVE + EXE in patients with HR+, HER2 - ABC in Asia and other emerging growth countries. Postmenopausal women with HR+, HER2 - ABC who had documented recurrence or progression, following a nonsteroidal aromatase inhibitor therapy, were treated with EVE (10 mg/day) + EXE (25 mg/day) orally. RESULTS: A total of 235 patients received ≥ 1 dose of study medication. At the end of the study, all patients ceased the treatment. Disease progression (66.0%) was the primary reason of discontinuation. The most common AEs (≥ 20%) were stomatitis, decreased appetite, hyperglycemia, rash, aspartate aminotransferase increased, anemia, alanine aminotransferase increased, cough, and fatigue. No new safety concerns were identified in the current study. Median progression-free survival (PFS) in the Asian subset was similar to that of the overall population (9.3 months in both groups). Confirmed overall response rate (ORR) was achieved for 19.6% of the patients. Efficacy of EVE + EXE across subgroups (prior CT, line of treatment, and presence of visceral metastases) was maintained. CONCLUSION: The safety and efficacy results from EVEREXES trial are consistent to data previously reported in BOLERO-2. These results support that EVE + EXE could be a viable treatment option for the postmenopausal women with HR+, HER2 - ABC in Asian region.

Chemotherapy-induced nausea and vomiting (CINV) may be linked to the psychological status of cancer patients. Therefore, the authors aimed to better understand the underlying risk factors for CINV using the Brief Illness Perception Questionnaire. A total of 238 patients were recruited during three cycles of chemotherapy. Patient, disease and treatment characteristics were noted at the onset of chemotherapy. The Brief Illness Perception Questionnaire was administered face-to-face prior to chemotherapy. The relationship between illness perceptions and CINV was analyzed using Spearman's rank correlation. Positive illness perception parameters, including personal and treatment control, were negatively correlated, whereas negative illness perception parameters, including consequences, timeline, identity, concern and emotions, were positively correlated with CINV after adjusting for age, sex and emetogenic potential of chemotherapy (p < 0.001). Illness perception may be an underlying risk factor for CINV.

BACKGROUND: 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. MATERIALS AND METHODS: 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. RESULTS: 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 (< 65 years). The 24-mo overall survival rate was 76.1% and 49.5% in the afatinib arm and erlotinib/gefitinib arm, respectively. Although all-grade adverse event (AE) rates were similar between the two arms, grade 3-4 AE rates were higher in the afatinib arm (30.7% vs. 15.2%; p: 0.004). DISCUSSION: In our real-world study, afatinib has superior survival outcomes despite worse toxicity profile as inconsistent with clinical study results and it is the good upfront treatment option for younger patients and elderly patients who have good performance status.

PURPOSE: The peritoneum is the common recurrence site of gastric cancer (GC) presenting with worse survival. Although some predictive clinicopathological factors have been identified, there is no comprehensive assessment of peritoneal recurrence risk prediction for patients treated with adjuvant chemotherapy (CR) or chemoradiotherapy (CRT) after surgery. We aimed to predict peritoneal recurrence and develop a new scoring model in GC. METHODS: This retrospective study included 274 GC patients who presented with recurrence after curative gastrectomy followed by adjuvant chemotherapy (CT) or chemoradiotherapy (CRT). Risk factors for peritoneal recurrence were analyzed using the following parameters: age, gender, tumor location and characteristics, and differences between treatment modalities. All parameters were assessed by binary logistic regression analysis to compare the patients with and without peritoneal recurrence. Then, a new risk scoring model was developed. RESULTS: Peritoneal recurrence was observed in 115 (44.1%) patients. Peritoneal recurrence was higher in female gender (odds ratio (OR), 1.93; 1.07-3.49, P = 0.030, 1 point), T4a-b stage (OR, 2.47; 1.14-5.36, P = 0.022, 1 point), poor/undifferentiated (OR, 2.04; 1.31-4.06, P = 0.004, 1 point), and signet cell carcinoma (OR, 2.04; 1.04-4.02, P = 0.038, 1 point) after adjusted for resection and dissection types. The risk scoring model was developed using the related parameters: Peritoneal recurrence rates were 24.6%, 42.6%, and 71.4% for group 1 (0 point), group 2 (1-2 points), and group 3 (3-4 points), respectively. CONCLUSION: Female gender, T4 tumor stage, undifferentiated histopathology, and signet cell type had a tendency to peritoneal recurrence after adjusted for treatment modalities. Patients with 3 or 4 risk factors had an 8.8-fold increased risk for the development of peritoneal recurrence.

ABSTRACT Objective: To evaluate the efficacy and safety of enzalutamide in metastatic castration-resistant prostate cancer (mCRPC) in docetaxel-naive and docetaxel-pretreated patients. STUDY DESIGN: Observational study. PLACE AND DURATION OF STUDY: HSU Dr. Abdurrahman Yurtaslan Oncology Training and Research Hospital, Department of Medical Oncology, Ankara, Turkey, from March 2017 to July 2019. METHODOLOGY: A total of 67 patients with mCRPC were retrospectively evaluated. Castration-naive patients and non-metastatic patients were excluded from the study. Comorbid diseases, ECOG performance status, PSA response, and the radiological response of the patients were recorded. Kaplan-Meier method was used for survival analysis, and a Cox regression model was formed. RESULTS: The overall survival (OS) was significantly longer in patients with eastern cooperative oncology group performance status (ECOG PS) 0 (26.0 vs. 14.0 months, p=0.031), PSA response (26.0 vs. 7.0 months, p=0.002), radiological response (26.0 vs. 10.0 months, p=0.006) and duration of enzalutamide ≥9 months (26.0 vs. 7.0 months, p<0.001) compared to ECOG PS 1. According to Cox regression analysis, patients with PSA response had 0.35 fold (CI.95% 0.13-0.94) reduced the risk of death and 0.36-fold (CI.95%0.16-0.85) reduced the risk of progression compared to those without PSA response. Moreover, longer enzalutamide treatment (≥9 months) was noted to decrease the risk of death. CONCLUSION: PSA response, radiological response and duration of enzalutamide treatment may predict the improvement of survival in patients with mCRPC treated with enzalutamide. Key Words: Enzalutamide, Docetaxel, Castration-resistant prostate cancer, Overall survival, Progression-free survival.

OBJECTIVE: The aim of this study is to determine the effect of breathing exercise on nausea, vomiting, and functional status in breast cancer patients undergoing chemotherapy. METHODS: This randomized controlled trial was conducted with a total of 60 breast cancer patients in the ambulatory chemotherapy unit of a university hospital. The data were collected using Patient Information Form, Functional Living Index-Cancer (FLI-C), Visual Analog Scale, and Patient Diary. The patients were followed up for the first seven days. While the control group received routine nursing care until the posttest, the intervention group received breathing exercise for six days. On the seventh day, FLI-C was repeated for all the patients. RESULTS: It was determined that the patients in the intervention group had less number of nausea, vomiting, and retching episodes after the breathing exercise (p < 0.05) and experienced lower severity of nausea (p < 0.05) compared to patients in the control group. CONCLUSION: Consequently, it was determined that the breathing exercise reduced chemotherapy-induced nausea, vomiting and retching in breast cancer patients and affected positively functional status of patients.

Lorlatinib is a third-generation tyrosine-kinases inhibitor (TKI) targeting ALK/ROS1 fusions. The FDA has approved lorlatinib for TKI-pretreated ALK(+) NSCLC, while its approval for ROS1(+) is still pending. Here we present the largest real-world data of NSCLC patients harboring ALK/ROS1 rearrangements treated with lorlatinib. METHODS: 123 patients were enrolled retrospectively (data cut-off 1/1/2019). Lorlatinib was administered through an early access program for patients with no other available therapy. Outcome and response were defined by each investigator upon RECIST 1.1 criteria. RESULTS: 106 ALK(+) and 17 ROS1(+) patients recruited from 8 different countries. The ALK(+) cohort included 50 % males, 73 % never-smokers and 68 % with brain metastases. Extracranial (EC) and intracranial (IC) response rates (RR) were 60 % and 62 %, with disease control rates (DCR) of 91 % and 88 % respectively. Mean duration of therapy (DoT) was 23.9⯱â¯1.6 months and median overall survival (mOS) was 89.1⯱â¯19.6 months. ROS1 cohort enrolled 53 % males, 65 % never-smokers and 65 % had brain metastases. EC and IC RR were 62 % and 67 % with DCR of 92 % and 78 % respectively. Median DoT was 18.1⯱â¯2.5 months and mOS of 90.3⯱â¯24.4 months. OS and DoT in both cohorts were not significantly correlated with line of therapy nor other parameters. The most common adverse events of any grade were peripheral edema (48 %), hyperlipidemia (47 %), weight gain (25 %) and fatigue (30 %). CNS adverse events such as cognitive effect of grade 1-2 were reported in 18 % of patients. CONCLUSION: Lorlatinib shows outstanding EC/IC efficacy in ALK/ROS1(+) NSCLC. The observed mOS of 89⯱â¯19 months in ALK(+) NSCLC supports previous reports, while mOS from of 90⯱â¯24 months is unprecedented for ROS1(+) NSCLC.

Aim: We aimed to investigate the impact of hepatosteatosis (HS) severity on the recurrence pattern of breast cancer and to clarify whether HS causes affinity to recurrence with liver metastasis. Materials & methods: The median follow-up was 80.0 (4-217) months and the mean age was 47.9 ± 11.3 years. Among all, 181 (39.9%) patients were diagnosed with grades 2 and 3 HS. Of total, 158 (34.8%) patients have experienced recurrence. Results: While higher degree of HS was more common in patients presented with liver recurrence (odds ratio; 95% CI: 2.50; 1.27-4.92; p = 0.007), it was lesser in those with other metastatic sites (all were >0.05). Liver-recurrence-free survival was significantly worse in the group with higher degree of HS (hazard ratio; 95% CI: 2.46; 1.4-4.3; p = 0.002) together with younger age (hazard ratio; 95% CI: 2.44; 1.4-4.3; p = 0.002) in multivariate analysis. Conclusion: HS might have produced an affinity for liver metastasis in common types of breast cancer patients in remission independent from metabolic disorders or clinicopathologic features.

OBJECTIVES: There is not yet a standardized approach to treat patients with small cell carcinoma of the bladder (SmCCB). This study aims to investigate the clinical features, treatment, and survival outcomes of patients with pure SmCCB. MATERIALS AND METHODS: Patients diagnosed with SmCCB between January 2006 and September 2015 were retrospectively evaluated. RESULTS: A total of 34 patients with a median age of 63.0 years were included in the study, with a male to female ratio of 4.6:1.0. At the time of diagnosis, 22 patients (64.7%) had stage IV disease. At a median follow-up time of 12.7 months, 67.6% of patients died of bladder carcinoma, with an overall survival (OS) of 15.7 months for all patients. In the patients with stages I-III, nodal involvement, and distant metastases, the median OS was 31.8, 15.7, and 8.4 months, respectively (P = 0.005). Considering the survival rates of the patients (stages I-III) treated with surgery vs. local therapy, there was not a statistically significant difference (26.6 months and 31.8 months, P = 0.97, respectively). A multivariate analysis revealed that stage IV disease and poor ECOG performance status were associated with OS. CONCLUSION: The optimal treatment of SmCCB has been under debate. For the patients with advanced stage of disease (T4b, N+, M+), platinum containing chemotherapeutic agents should be preferred. Stage IV disease and poor ECOG performance status were associated with shorter OS.

AIM: The positive energy balance and insulin resistance caused by weight gain, physical inactivity, poor dietary quality are linked to a decreased breast cancer (BC)-specific survival. The aim of the present study was to assess whether or not hepatosteatosis, which reflect underlying insulin resistance, has a predictive value on recurrence in patients with nonmetastatic BC. MATERIAL METHOD: All diagnosed nonmetastatic BC patients between 2005 and 2016 were included in this retrospective analysis. Patients' medical characteristics included for analysis were age, menopausal status, presence of obesity, diabetes, dyslipidemia, and tumor features. Liver parenchyma was evaluated by ultrasonography, and then patients divided into 2 groups according to final follow-up findings; group 1: without hepatosteatosis or presence of grade 1 steatosis; group 2: presence of grades 2 and 3 hepatosteatosis. Survival distributions were estimated with the Kaplan-Meier method and compared between groups with the log-rank statistic. RESULTS: Four hundred twenty-four patients included in this study. The median follow-up period of all patients was 6.7 years (range, 0.6-13 years). The mean age was 48.2 ± 0.5 years. Of total, 154 (36.3%) patients experienced recurrence. In total, 171 (40.6%) patients had grades 2 and 3 hepatosteatosis, and the remaining had no, or grade 1 hepatosteatosis during last follow-up or at recurrence. The clinicopathologic characteristics of the participants were well balanced between the 2 groups. Younger age (odds ratio [OR]: 2.19; 95% confidence interval [CI]: 1.3-3.8, P = 0.005), and higher tumor stage (OR: 7.52; 95% CI: 1.2-48.5, P = 0.035 for stage Ia vs stage IIIC) were associated with recurrence of BC during the entire follow-up in multivariate analysis. Hepatosteatosis predicted late recurrence after 5 years in nonmetastatic BC after adjusted for age, diabetes, tumor stage, grade, and luminal type (OR: 2.45; 95% CI: 1.1-5.6, P = 0.034) and the hazard ratio was 0.40 (95% CI: 0.18-0.88, P = 0.023 adjusted value) for relapse-free survival after 5 years. CONCLUSION: Higher degree of hepatosteatosis may predict recurrence after 5 years in BC survivors.
