The relationship between clinical and pathological findings and FDG - PET uptake in metastatic colorectal cancers.

Background: In metastatic colorectal cancer (mCRC), the genetic structure and cell metabolism of the primary tumor lesion might be different from metastatic lesions. It is thought that cell-level glucose metabolism may differ due to the difference in RAS wild and mutant mCRC patients' prognosis. In this study, we aimed to compare 2-deoxy-2-[fluorine-18]-fluoro-D-glucose Positron Emission Tomography (18F-FDG PET/CT) uptake levels for KRAS mutation status and primary-metastatic tumor localization.

Assessment of PD-L1 expression in patients with neuroblastoma and renal tumors.

Background: Programmed death 1 (PD-1) is a co-receptor which is located at the surface of cells like natural killer, monocytes, T and B cells. It has two ligands including programmed death ligand-1 (PD-L1) and ligand-2 (PD-L2). T cell functions are inhibited by activation of PD-1/PD-L1 pathway and this pathway is used by viruses and some tumor cells in order to escape from immune eradication.

Folfirinox versus gemcitabine-cisplatin combination as first-line therapy in treatment of pancreaticobiliary cancer.

Background/aim: The purpose of this study was to compare efficacy and safety of a combination chemotherapy regimen consisting of oxaliplatin, irinotecan, fluorouracil, and leucovorin (FOLFIRINOX) and gemcitabine-cisplatin as first-line therapy in patients with pancreatic cancer.

Materials And Methods: Pancreaticobiliary cancer patients who had Eastern Cooperative Oncology Group performance status score of 0 or 1 (on a scale of 0 to 5, with higher scores indicating greater severity of illness) were evaluated to receive folfirinox or gemcitabine plus cisplatin. The primary endpoints were progression-free and overall survival time.

The impact of the menstrual cycle on intra-operative and postoperative bleeding in abdominoplasty patients.

Background: Hormonal changes that take place during the menstrual cycle may have an effect on perioperative bleeding. Previous studies have confirmed a relationship between the menstrual cycle and surgical bleeding in rhinoplasty and breast reduction surgery; yet both surgical sites display changes in accordance with sex hormone levels during the menstrual phase.

Aim: The aim of this study was to determine the effect of the menstrual cycle on perioperative bleeding when undergoing surgeries of sites not directly related to menstrual hormonal changes.

Quetiapine use for the treatment of manic episode during pregnancy.

The foregoing is a case report about a 30-year-old woman, who was referred to our psychiatry clinic with a clinical picture of manic episode, at the 21st week of her first pregnancy. She had a history of bipolar affective disorder for 12 years, had two previous manic episodes and had stopped taking lithium 6 months ago because of her plans to become pregnant. Quetiapine was begun and the dose was slowly increased to 1200 mg/day after 2 weeks.
