RESUMEN
BACKGROUND: Prognostic factors and the standard treatment approach for gynaecological carcinosarcomas have not yet been clearly defined. Although carcinosarcomas are more aggressive than pure epithelial tumours, they are treated similarly. Serous/clear cell and endometrioid components may be predictive factors for the efficacy of adjuvant chemotherapy (CT) or radiotherapy (RT) or RT in patients with uterine and ovarian carcinosarcomas. Heterologous carcinosarcomas may benefit more from adjuvant CT. AIMS: We aimed to define the prognostic and predictive factors associated with treatment options in ovarian (OCS) and uterine carcinosarcoma (UCS). STUDY DESIGN: Retrospective cross-sectional study. METHODS: We retrospectively reviewed the medical records of patients with ovarian and uterine carcinosarcoma from 2000 to 2013, and 127 women were included in this study (24 ovarian and 103 uterine). Patients admitted to seventeen oncology centres in Turkey between 2000 and December 2013 with a histologically proven diagnosis of uterine carcinosarcoma with FIGO 2009 stage I-III and patients with sufficient data obtained from well-kept medical records were included in this study. Stage IV tumours were excluded. The patient records were retrospectively reviewed. Data from 104 patients were evaluated for this study. RESULTS: Age (≥70 years) was a poor prognostic factor for UCS (p=0.036). Pelvic±para aortic lymph node dissection did not affect overall survival (OS) (p=0.35). Macroscopic residual disease was related with OS (p<0.01). The median OS was significantly longer in stage I-II patients than stage III patients (p=0.03). Adjuvant treatment improved OS (p=0.013). Adjuvant radiotherapy tended to increase the median OS (p=0.075). However, this tendency was observed in UCS (p=0.08) rather than OCS (p=0.6).Adjuvant chemotherapy had no effect on OS (p=0.15).Adjuvant radiotherapy significantly prolonged the median OS in patients with endometrioid component (p=0.034). A serous/clear cell component was a negative prognostic factor (p=0.035). Patients with serous/clear cell histology for whom adjuvant chemotherapy was applied had significantly longer OS (p=0.019), and there was no beneficial effect of adjuvant radiotherapy (p=0.4). Adjuvant chemotherapy was effective in heterologous tumours (p=0.026). In multivariate analysis, the stage and chemotherapy were prognostic factors for all patients. Age was an independent prognostic factor for UCS. However, serous/clear cell histology and radiotherapy tended to be significant prognostic factors. CONCLUSION: The primary location, the histological type of sarcomatous and the epithelial component may be predictive factors for the efficacy of chemotherapy or radiotherapy in UCS and OCS.
RESUMEN
PURPOSE: Medulloblastoma (MB) is rarely seen in adults. For adjuvant therapy in adults the same therapy protocols used in pediatric cases are used. The present study retrospectively evaluated the data of MB patients who were treated in different Oncology Centers in Turkey. METHODS: The data of 60 adult patients with MB from 8 Oncology Centers diagnosed between 2005 and 2012 were retrospectively analyzed. RESULTS: The median patient age was 28.8 years (range 16-54). The administered chemotherapy included procarbazine+lomustin+vincristine (group A, N=31) and cyclophosphamide/ifosfamide+vincristine+cisplatin (group B, N=13). Median chemotherapy courses were 4 (range 1-8). Median progression free survival (PFS) was 76 months and median overall survival (OS) has not been reached in both groups. In young female patients and in those who received adjuvant chemotherapy, median PFS and OS were longer but without statistical significance. Mean PFS and OS were 65.9 months and 101.2 months in group A and 113.6 months and 141.6 months in group B, respectively. CONCLUSION: Improved survival results were obtained in women, in patients aged below 25 years, in those who underwent gross total excision (GTE) and in those who received adjuvant therapy with cyclophosphamide/ifosphamide.

OBJECTIVE: Currently, medical and surgical treatment options for endometriosis are limited due to suboptimal efficacy, and also safety and tolerance issues. Long-term use of gonadotrophin-releasing hormone analogs, androgenes, and the danazol, which are widely used drugs for endometriosis, is usually not possible due to their suboptimal safety and tolerance profile. The lack of an effective, tolerable and safe treatment option for endometriosis makes animal models of experimental endometriosis necessary to study candidate drugs. The aim of this study was to investigate the efficacy of imatinib on the experimental endometriosis in a rat model. STUDY DESIGN: Endometriosis was induced by autotransplantation of uterine tissue into the peritoneal cavity. Twenty-four rats, which had visually confirmed endometriotic implants on subsequent laparotomy, were randomized into three groups to receive imatinib (25mg/kg/day, p.o.), anastrozole (0.004 mg/day, p.o.), or normal saline (0.1 mL, i.p.) for 14 days. After removal of endometriotic tissue and H & E staining, endometriosis score was determined according to a semiquantitative histological classification. Also, immunostaining with primary antibodies including VEGF, CD117, and Bax were used for immunohistochemical (IHC) examination. RESULTS: Both anastrozole and imatinib suppressed the growth of endometriotic tissue and reduced the number of ovarian follicles. Although the difference was not statistically significant, imatinib was less effective than anastrozole for treatment of endometriosis. CONCLUSION: Imatinib effectively treats experimental endometriosis by its inhibitor effects on angiogenesis and cell proliferation.

AIM: We investigated the clinicopathological features in patients with recurrent RCC within 5 years or more than 5 years after nephrectomy and determined predictors of survival and response treatment after recurrence. MATERIALS AND METHODS: We retrospectively evaluated 144 patients with disease recurrence; 73 had recurrence more than 5 years after radical nephrectomy. We compared clinicopathological characteristics in patients with disease recurrence before vs. after 5 years. In addition, we investigated predictors of survival and response to treatment after recurrence. RESULTS: Seventy-one patients (49%) were diagnosed with recurrence within 5 years after radical nephrectomy (early recurrence) and 73 patients (51%) were diagnosed with recurrence more than 5 years after radical nephrectomy (late recurrence). Fuhrman grade, tumor necrosis and lymphovascular invasion were statistically significantly different between the two groups (p<0.001, p=0.013, p=0.026, respectively). The late recurrence patients were significantly associated with the Memorial Sloan Kettering Cancer Center (MSKCC) favorable risk group compared to patients with early recurrence (p=0.001). From the time of disease recurrence, median Overall Survival (OS) was 36.0 (95% Confidence Interval (CI) 30.7-41.2) months in the late recurrence group, and 19 (95% CI 15.4-22.5) months in the early recurrence group (p=0.01). The median Progression Free Survival (PFS) was 6 (95% CI 3.87-8.12) months in the early recurrence group, and 18 (95% CI 15.4-20.5) months for the late recurrence group (p<0.001). CONCLUSION: Early recurrence was significantly associated with Fuhrman grade 3-4, tumor necrosis, lymphovascular invasion, MSKCC poor-risk group compared to patients with late recurrence. The study also demonstrated a potential prognostic value of late recurrence in terms of PFS and OS.

BACKGROUND: Although many prognostic factors have been identified for lung cancers, new ones are needed to determine the course of the disease. Recently, a high neutrophil to lymphocyte ratio (NLR) prior to surgery or treatment has been shown to be an indicator of prognosis for cancer. The aim of this study was to investigate the value of NLR as a prognostic factor and the correlation between NLR and other probable clinical prognostic factors in non small cell lung cancer patients prior to treatment. MATERIALS AND METHODS: Data of patients who were diagnosed with non-small cell lung cancer in our institution were retrospectively reviewed. Demographic and clinicopathologic characteristics were recorded. NLR was calculated before the application of any treatment. RESULTS: A total of 299 patients, 270 (90%) males and 29 (10%) females, were included in the study. Age (p<0.001) stage (p<0.001), Eastern Cooperative Oncology Group performance status (p<0.001), weight loss (p<0.001), anemia (p<0.001), histopatology (p<0.001), NLR ≥ 3 (p=0.048), NLR ≥ 4 (p=0.025) and NLR ≥ 5 (p=0.018) were found to be the prognostic factors. Age, anemia, Eastern Cooperative Oncology Group performance status, the stage, NLR (≥ 5) were an independent prognostic factors. There was a positive correlation between NLR and the Eastern Cooperative Oncology Group performance status (0.23, p=0.001), the C reactive protein levels (r=0.36, p<0.001). CONCLUSIONS: Prior to treatment high NLR was found as an independent poor prognosis factor. Besides, NLR correlated with Eastern Cooperative Oncology Group performance status and the C reactive protein levels.

BACKGROUND: Effect of comorbidity on the treatments that patients receive is not clear, as healthy elderly patients and the elderly with less comorbid diseases are included in the studies. In the present study, the effect of comorbidity on the survival was evaluated using Charlson Comorbidity Index (CCI) and Cumulative Illness Rating Scale (CIRS). MATERIAL AND METHOD: The general features and comorbid diseases of the pancreatic cancer patients were retrospectively screened from the patient files using the automated system. CCI and CIRS were used as the comorbidity indices. RESULTS: A total of 106 patients with pancreatic cancer were included in the study. The median overall survival rate was 9.0 [95 % confidence interval (CI): 6.7-11.3] months. The median overall survival rate was found as 9.4 (95 % CI: 6.7-12.1) months in the patients whose CCI score was ≤ 2 and was found as 6.2 (95 % CI: 4.0-8.3) months in the patients with CCI scores ≥ 3 (p = 0.05). The median overall survival rate was calculated as 9.8 (95 % CI: 6.3-13.4) months in the patients with CIRS scores ≤ 2 and was calculated as 8.3 (95 % CI: 6.0-10.6) months in the patients with CIRS scores ≥ 3 (p = 0.51). When surgery, radiotherapy, grading, and CCI score were evaluated using multivariate analysis, it was observed that only the treatment modality had a significant effect on the survival rate. CONCLUSION: The results on the use of comorbidity indices are contradictory for the cancers with lower survival rates such as pancreatic cancer. New prognostic scales might be developed for this patient group by considering the side effects of chemotherapy.

BACKGROUND/AIM: Gastric cancer (GC) is considered to be a disease of elderly patients. It has been suggested that GC in young adults has more aggressive clinical and pathologic features than in adults. In this study we aimed to evaluate clinical and pathologic features of GC under age 40 years. PATIENTS AND METHODS: Patients included in this study were those treated and followed up for GC under age 40 years in Ankara Numune Education and Research Hospital from 2002 to 2011. RESULTS: Clinical and pathologic features of 82 patients have been evaluated retrospectively. Of the patients 44 were male (54%) and 38 were (46%) female, and the median age was 35 years (min-max: 18-40 years). The tumor was grade 3 in 77% of the patients, 79% had diffuse type tumor, 64% had lymphovascular invasion, and 76% had perineural invasion. Forty-seven patients (57%) were metastatic at the time of diagnosis. The median follow up was 9 (1-101) months. The median overall survival (OS) was 9 months in metastatic patients and 8-year OS was 64% in nonmetastatic patients. CONCLUSIONS: We observed that young GC patients had more aggressive histopathologic features and more than half was metastatic at the time of diagnosis. We need more studies comparing young and elderly patients to confirm that young patients had more aggressive disease.

The aim of this study was to evaluate prognostic factors, survival rate and the efficacy of the treatment modalities used in patients with Ewing sarcoma family of tumors (ESFT). Data of patients with ESFTs followed up at different cancer centers in Turkey between 2001 and 2010 were retrospectively analyzed. The median age of 114 patients was 26 years (range 14-66). The median follow-up was 20 months (range 1-118 months). Tumor size was between 1.5 and 14 cm (median 8 cm). Eighty-six percent of patients had localized disease at presentation, and 14 % had metastatic disease. Local therapy was surgery alone in 31 % of patients, surgery combined with radiotherapy in 41 % and radiotherapy alone in 18 %. Approximately 70 % of patients were treated with vincristine, doxorubicin, cyclophosphamide and actinomycin-D, alternating with ifosfamide and etoposide every 3 weeks. In patients with localized disease at presentation, the 5-year disease-free survival and overall survival were 60 and 65 %, respectively. At univariate analysis, patients with tumor size ≥ 8 cm, high serum lactate dehydrogenase, metastasis at presentation, poor histological response to chemotherapy and positive surgical margin had significantly worse event-free survival. The significant predictors of worse overall survival at univariate analysis were tumor size ≤ 8 cm, high lactate dehydrogenase, metastasis at presentation, poor histological response to chemotherapy, radiotherapy only as local treatment and positive surgical margin. ESFTs are aggressive tumors with a high incidence of local recurrence and distant metastasis. Multimodality treatment consisting of adequate surgical resection, aggressive chemotherapy (VAC alternating with IE) and radiotherapy is recommended for patients with ESFTs.
