Item Concurrent chemoradiotherapy with weekly carboplatin and paclitaxel may be a feasible option in inoperable stage III non-small cell lung cancer: a single center experience(2019) Calikusu, Zuleyha; Sedef, Ali Murat; Saltaoglu, PinarPurpose: Concurrent chemoradiotherapy (CCRT) is a standard treatment for patients with unresectable stage III non-small cell lung cancer (NSCLC). An optimal chemotherapy regimen with concurrent thoracic radiotherapy is not known. In this study, we investigated the efficacy and toxicity of CCRT with carboplatin [area under curve (AUC) 2] and paclitaxel (80 mg/m(2)) during CCRT. Materials and Methods: We performed a retrospective survival analysis using medical records of 40 patients with inoperable stage III NSCLC that were treated with concurrent chemoradiotherapy with carboplatin-paclitaxel (AUC 2, 60 mg/m2). Results: The most common histopathology was adenocarcinoma, which was diagnosed in 18 patients (45%). There were 12 stage IIIA patients (30%) and 28 stage IIIB patients (70%). The median follow-up time was 22.5 months [95% confidence interval (CI), 2.9-72.2]. Median disease-free survival (DFS) and overall survival (OS) were 22.5 months (95% CI, 18.1-27.0) and 53.5 months (95% CI, 23.5-82.8). Grade 3-4 hematological and non-hematological toxicities were seen in 8 (20%) and 5 (12.5%) patients, respectively. Conclusion: This study showed that CCRT with weekly carboplatin-paclitaxel provides similar outcomes to cases in the literature and the regimen seems to be feasible with a low rate of grade 3-4 toxicity during CCRT of non operable stage III NSCLC.

Platinum-etoposide chemotherapy combination is used as first line treatment. The aim of this trial is evaluate the effect of complete response rates and clinical features in patients with extensive stage (ES) SCLC. METHODS In this retrospective study, a total of 117 patients from four different oncology centers in Turkey between 2011 and 2017 were divided into 2 groups, namely, patients with complete response (group 1) and those with no complete response (group 2) after platin-etoposide combination therapy. RESULTS The median age of the patients was 61 (range 38-81) years. The median follow-up time was 12 months and 95 (81%) patients died. Progression-free survival (PFS) and overall survival (OS) were estimated, respectively, as 8 and 13 months. Overall survival of group 1 patients was statistically significantly better than the group 2 (16 versus 10 months respectively and p=0.00). The overall survival of patients who had late recurrent disease (>6 mo.) was statistically significantly better than the early ones (<6 mo) (19 versus 14 months respectively and p=0,008). CONCLUSION Complete response and recurrent free time were the prognostic factors for ES SCLC patients in our studyItem Treatment outcomes of early stage endometrial cancer patients: single center experience(2019) Sedef, Ali Murat; Karaduman, Didem; Besen, Ali Ayberk; Mertsoylu, Huseyin; Kose, FatihPurpose: The aim of this study was to evaluate clinicopathological characteristics and treatment outcomes of early stages endometrial cancer patients in our center. Materials and Methods: This study was a hospital-based retrospective observational case-series study. 116 patients were included in the study from Baskent University Department of Medical Oncology and Gynecological Oncology between the years of 2009-2015. De-novo metastatic patients were not included in the study. Results: The median age of the patients was 58 (range 27-81) years. All of patients had European Cooperative Oncology Group (ECOG) performance score 0 (n:116). Endometrioid histology was the most common histopathological subtype (n:103, 88%). All of the patients were in local and local advanced stage. The significant percentage of patients had grade 2 tumor (n:55, 47.4%). Myometrial invasion was less than 50% in 78 patients (67.2 %). The median follow-up time was 61 months and 8 (6.9%) patients died. All patients underwent standard surgical staging with standard lymphadenectomy. Overall survival (OS) was not reached. There were 14 patients (12.1 %) and 34 patients (29.3 %) treated with adjuvant chemotherapy and radiotherapy, respectively. Conclusion: Though endometrial cancer is the most common gynecological tumors in women, cure rate is very high. Relapse rate was 6 % (7 patients) and most of the relapse were local, 71.4% (5 patients)Item Primary Extranodal Non-Hodgkin's Lymphoma: Clinicopathological Features, Survival and Treatment Outcome in Two Cancer Centers of Southern Turkey(2014) Mertsoylu, Huseyin; Muallaoglu, Sadik; Besen, Ayberk Ali; Erdogdu, Suleyman; Sezer, Ahmet; Sedef, Ali Murat; Kose, Fatih; Arican, Ali; Ozyilkan, OzgurBackground: 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.Item Targeted treatment with pazopanib in metastatic soft tissue sarcoma: Nearly complete response in two cases(2015) Sedef, Ali Murat; Kose, Fatih; Dogan, Ozlem; Ergun, Tarkan; Sezer, Ahmet; Mertsoylu, Hoseyin; Muallaoglu, Sadik; Besen, Ayberk; Ozyilkan, Ozgur; 25798275Soft tissue sarcomas (STS) are a group of rare mesenchymal cancers that include approximately 50 histological types and account for 1% of all adult cancers. The standard curative treatment option for localized disease is surgical resection and, if a surgically removed tumor exhibits high-risk characteristics, adjuvant chemotherapy and radiotherapy may be administered. Sarcoma presenting at an advanced stage has a dismal prognosis and survival has not markedly improved over the last 20 years. The standard first-line treatment for advanced STS, other than gastrointestinal stromal tumors, is cytotoxic chemotherapy. Therapies targeting pro-angiogenic factors have been a focus of drug development for STS over the last few years. Pazopanib, a multitargeted tyrosine kinase inhibitor, is a novel treatment option for patients with metastatic STS in the second-line setting. This is a presentation of 2 case reports of patients with metastatic STS who responded well to treatment with pazopanib.Item Clinicohistopathological features and treatment outcomes of neuroendocrine tumors: a single center experience(2018) Kose, Fatih; Sedef, Ali Murat; Sumbul, Ahmet Taner; Mertsoylu, Huseyin; Besen, Ali Ayberk; Sezer, Ahmet; Ozyilkan, Ozgur; Abali, Huseyin; D-4793-2014Purpose: Tumor and patient characteristics of neuroendocrine tumors (NET) significantly change between geographical locations that probably induced by environmental and genetic factors throughout the world. Therefore, reporting single center experience may help clarifying epidemiological view and improving decision-making process. Materials and Methods: We performed retrospective analysis of 115 patients of NETs those who followed by Baskent University, department of Medical Oncology and department of General Surgery to record patients and tumors characteristics, treatment modalities, survival rates, and prognostic factors. Results: Median overall survival (OS) time for all group and localized NETs were 44 and 24 months, respectively. Most common primary site was found as gastrointestinal system and then pancreatic region. Curative surgical resection rate was 46% and 8.5% of patients presented with carcinoid syndrome. Liver metastasis was far the most common metastatic site compared to lung, bone, and lymph node metastasis. Over 70 percent of patients were treated with chemotherapy and somatostatin analogs. Conclusion: Patients with higher grade, male gender, and advanced age (>65 years old) had poor survival rate. However, relatively low number of patients and less usage of (<10%) of new treatment modalities created limitations for producing future directions from our study.Item Prognostic value of basal neutrophil lymphocyte ratio in patients with extensive stage small cell lung cancer(2018) Besen, Ali Ayberk; Sedef, Ali Murat; Calikusu, Zuleyha; Bahceci, Aykut; Gokcay, Serkan; Sumbul, Ahmet Taner; D-4793-2014Purpose: The neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and lymphocytopenia are markers of poor prognosis in lung cancer patients. The aim of this trial is evaluate the prognostic significance of basal NLR, PLR and lymphocytopenia in patients with extensive stage (ES) small cell lung cancer(SCLC). Materials and Methods: This study was designed as a hospital-based retrospective observational case-series study. A total of 117 patients with extensive stage small cell lung cancer have been treated at four different oncology centers in Turkey between 2011 and 2017. Laboratory results and demographic data were collected. Results: The median follow-up time was 12 months and 95 (81%) patients died. Progression-free survival (PFS) and overall survival (OS) were estimated, respectively, as 8 and 13 months. 65 (55.6 %) patients had complete response at the end of first line platin-etoposide combination treatment. The cut-off value for NLR and PLR were determined for whole group and patients were dichotomized into high (>= 3.28) and low (<3.28) NLR groups and high (>= 139.8) and low (< 139.8) PLR groups.. Median OS was lower in patients who had high neutrophil lymphocyte ratio (NLR) (14 versus 12 months respectively). Conclusion: This study showed that basal NLR may have prognostic biological value in patients with ES SCLC treated with cisplatin + etoposide.
