Aim: To determine prognostic value of blood parameters on overall and progression-free survival in cases received adjuvant radiotherapy and chemotherapy with diagnosis of stage I-III breast cancer. Materials and Methods: We retrospectively reviewed files of 350 patients with non-metastatic breast cancer who were treated in the Radiation Oncology Department of Kayseri Teaching Hospital between 2005 and 2010. Pretreatment white blood cell (WBC), neutrophil, monocyte, basophil and eosinophil counts, and the neutrophil/lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR) were recorded. The relationship between clinicopathological findings and blood parameters was assessed. Results: Overall, 344 women and 6 men were recruited. Median age was $55.3{\pm}0.3$ years (range: 22-86). Of the cases, 243 (61.4%) received radiotherapy while 329 (94.3%), received chemotherapy and 215 (61.4%) received hormone therapy. Mean overall survival (OS) and progression-free survival (PFS) was 84.4 and 78.8 months, respectively. During follow-up, 48 patients died due to either disease-related or non-related causes. Local recurrence was detected in 14 cases, while distant metastasis was noted in 45 cases. In univariate analysis, age, pathology, perinodal invasion were significantly associated with overall survival, whereas gender, stage and hormone therapy were significantly associated with progression-free survival. In multivariate analysis, histopathological diagnosis (OR: 0.3; 95%: 0.1-0.7; p=0.006) and perinodal invasion (OR: 0.1; 95% CI: 0.1-1.3; p=0.026) were significantly associated with overall survival, whereas tumor stage (OR: 2.1; 95% CI: 0.0-0.7; p=0.014) and hormone therapy (OR: 2.1; 95%: 1.2-3.8; p=0.010) were significantly associated with progression-free survival. Conclusions: It was found that serum inflammatory markers including WBC, neutrophil, lymphocyte and monocyte counts, and NLR and PLR had no effect on prognosis in patients with breast cancer who underwent surgery and received adjuvant radiotherapy and chemotherapy.

Background: This study aimed to evaluate the baseline white blood cell (WBC), neutrophil, lymphocyte, monocyte, basophil, eosinophil count, total prostate-specific antigen (TPSA), free PSA (FPSA) level, neutrophilto- lymphocyte and neutrophil-to-monocyte ratios among patients with prostate cancer and benign prostatic hyperplasia (BPH), as well as healthy individuals. Materials and Methods: 2005-2012 laboratory files of 160 patients with prostate cancer at Kayseri Training and Research Hospital, Oncology Outpatient Clinic, 285 patients who were pathologically diagnosed with BPH in Urology Outpatient Clinic and 200 healthy individuals who were admitted to Internal Medicine Outpatient Clinic were retrospectively analyzed. Baseline WBC, neutrophil, lymphocyte, monocyte, basophil, eosinophil count, TPSA, FPSA level, neutrophil-to-lymphocyte ratio and neutrophil-to-monocyte ratio were recorded and compared across groups. Results: Patients with prostate cancer had a lower lymphocyte level compared to the patients with BPH and healthy controls (p<0.001). The mean monocyte count, leukocyte-to-monocyte ratio, and leukocyte-to-lymphocyte ratio were higher in patients with prostate cancer, but without significance. The mean WBC and leukocyte count were lower in patients with prostate cancer, but again without statistical significance (p=0.130). The mean TPSA and FPSA were 39.4 and 5.67, respectively in patients with prostate cancer, while they were 5.78 and 1.28 in patients with BPH. There was a significant difference in the mean TPSA and FPSA levels between the patient groups (p<0.001). Conclusions: Our study results showed that patients with prostate cancer had a lower level of lymphocytes, neutrophils and WBCs and a higher level of monocytes with a significant difference in lymphocyte count, compared to healthy controls. We suggest that lymphocyte count may be used in combination with other parameters in the diagnosis of prostate cancer, thanks to its ease of assessment.

Background: To determine prognostic value of excision repair cross-complementation 1 (ERCC1) in patients with malignant pleural mesothelioma (MPM). Materials and Methods: The study included 60 patients with MPM who were diagnosed and treated in the Radiation Oncology Department of Kayseri Teaching Hospital and Medical Oncology Department of Erciyes University, Medicine School between 2005 and 2013. By using immunohistochemical methods, ERCC1 expression in biopsy specimens was evaluated. We retrospectively assessed whether there is a correlation between ERCC1 and response to anti-neoplastic therapy or survival. Results: There were 50 men and 10 women with median age of 62 years (range: 39-83). Histological type was epithelial mesothelioma in the majority of the cases (85%), most commonly presenting in stage four. Of the cases, 20 (33%) received radiotherapy, 60 (%100) received first-line chemotherapy and 15 (%25) received second-line chemotherapy. In the assessment after therapy, it was found that there was partial response in 12 cases (20%), stable disease in 19 cases (31.4%) and progression in 25 cases (41.7%). ERCC1 was positive in 43% of the cases. Mean OS was 11.7 months and mean DFS was 9.5 months in ERCC1-positive cases regardless of therapy, while they were 19.2 months and 17.1 months in ERCC1-negative cases, respectively. The difference was found to be significant (p<0.05). In univariate analysis, stage, comorbidity, response to treatment and ERCC1 expression were found to be significantly associated with OS (p=0.083; p=0.043; p=0.041; p=0.050). In multivariate analysis, response to treatment remained to be significant for OS (p=0.005). In univariate and multivariate analyses, response to treatment and ERCC1 were found to be significantly associated with DFS (p=0.049; p=0.041). Conclusions: ERCC1 was identified as poor prognostic factor in patients with MPM.

Background: The influence of season of diagnosis on cancer survival has been an interesting issue for many years. Most studies have shown a possible association between seasonality and survival in some cancers. We aimed to investigate whether there is an association between season of diagnosis and survival in patients with gastric cancer. Materials and Methods: We reviewed retrospectively the files of 279 histologically proven gastric cancer patients. According to diagnosis date, the patients were grouped into 4 seasons of diagnosis groups, spring, summer, autumn, and winter. Results: There was no significant differences when the overall survival rates of the patients were compared according to the patients' season of diagnosis (p: 0.871). Median overall survival rates were 22.0 (14.5-29.5) months for the patients who were diagnosed in spring, 24.0 (12.4-35.6) for summer, 18.0 (9.96-26.0) for autumn and 21.0 (16.3-25.7) for winter. Median disease-free survival rates were 66.0 (44.1-68.1) months for the patients who were diagnosed in spring, 28.0 (17.0-39.0) for summer, 22.0 (0-46.4) for autumn and 23.0 (17.5-28.5) for winter. While the rate was best for the patients diagnosed in spring the differences were not statistically significant (p= 0.382). Conclusions: On the basis of the above results the season was not suggested as contributing to prognosis in gastric cancer cases in Kayseri, Turkey.
