A retrospective analysis on first-line bevacizumab, cetuximab, and panitimumab-containing regimens in patients with RAS-wild metastatic colorectal cancer: A Collaborative Study by Turkish Oncology Group (TOG).

Purpose: To compare the efficacy and adverse effect profiles of the first-line treatment of patients with KRAS wild type metastatic colorectal cancer (CRC) in Turkey who were treated based on regimens including bevacizumab, cetuximab and panitumumab.

Methods: This retrospective multicenter observational study involved a total of 238 patients who received chemotherapy in combination with either bevacizumab or cetuximab or panitumumab as first-line therapy for KRAS wild-type metastatic colorectal cancer. Patients with full medical records having pathological diagnosis of CRC adenocarcinoma were included in the study.

Prognostic factors of patients who received chemotherapy after cranial irradiation for non-small cell lung cancer with brain metastases: A retrospective analysis of multicenter study (Anatolian Society of Medical Oncology).

Purpose: Almost half of all patients diagnosed with non-small cell lung cancer (NSCLC) have distant metastases at presentation. One-third of patients with NSCLC will have brain metastases. Without effective treatment, the median survival is only 1 month.

The maximum standardized uptake value of metastatic site in 18 F-FDG PET/CT predicts molecular subtypes and survival in metastatic breast cancer: An Izmir Oncology Group study.

Purpose: The purpose of this study was to analyse the association between the 18F-2-deoxy-2-fluorodeoxyglucose maximum standardized uptake value (SUVmax) of metastatic sites and molecular subtypes and survival in metastatic breast cancer (MBC) patients.

Methods: Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) was performed in 176 MBC patients before any therapeutic intervention. The FDG uptakes of metastatic sites were evaluated using the SUVmax.

Role of increased mean platelet volume (MPV) and decreased MPV/platelet count ratio as poor prognostic factors in lung cancer.

Objectives: In this study, they investigated whether mean thrombocyte volume (MPV) and MPV/platelet count ratio have a prognostic significance in advanced NSCLC or not.

Methods: A total of 496 NSCLC patients at stage IIIB/IV and did not meet exclusion criteria were included in the study. The demographic features (age, gender, smoking habit), clinical characteristics (performance status, weight loss, disease stage, first-line treatment regimen), laboratory tests (levels of hemoglobin, lactate dehydrogenase and calcium as well as MPV, MPV/platelet count ratio and counts of white blood cell, platelet), and histological features (histologic type, tumor grade) were recorded.

The mean platelet volume may predict the development of isolated bone metastases in patients with breast cancer: a retrospective study of the Young Researchers Committee of the Turkish Oncology Group (TOG).

Purpose: To determine the predictive value of the mean platelet volume (MPV) and the MPV/platelet count ratio on the development of isolated bone metastasis in patients with breast cancer.

Methods: A total of 121 previously untreated female patients with isolated bone metastases from breast cancer (group 1) were included in this retrospective cohort study. The patients enrolled in this study had similar age, biological subtypes, and duration of follow-up after diagnosis.
