Large Unstained Cells (LUC): A Novel Predictor of CDK4/6 Inhibitor Outcomes in HR+ HER2-Negative Metastatic Breast Cancer.

: Although CDK4/6 inhibitors combined with endocrine therapies have improved outcomes in HR+ HER2-negative metastatic breast cancer, predictive biomarkers for treatment response and adverse effects remain limited. This study assessed the prognostic and predictive value of large unstained cells (LUC), a subset of white blood cells that may reflect immune status or treatment response. : A retrospective analysis of 210 patients with HR+ HER2-negative metastatic breast cancer treated with CDK 4/6 inhibitors between 2021 and 2024 was conducted.

A current comprehensive role of immune-checkpoint inhibitors in resectable non-small cell lung cancer: A narrative review.

Objective: The objective of this article is to review the efficacy, safety, and evidence for current use and potential future uses of immune-checkpoint inhibitors (ICIs) in the management of resectable non-small cell lung cancer (NSCLC).

Data Sources: A literature review was carried out through PubMed to identify completed and ongoing clinical trials evaluating the use, efficacy, and safety of ICIs in the management of resectable NSCLC.

Data Summary: To date, four phase 3 trials have emerged that have changed our treatment practice concerning the utilization of ICIs during the adjuvant and neoadjuvant settings.

Retrospective Evaluation of the Efficacy of Gemcitabine-Based Therapies After FOLFIRINOX Failure in Advanced Pancreatic Cancer, Multi-Center Real-Life Data.

Objective: Combination therapies such as FOLFIRINOX or gemcitabine-nanoparticle albumin-bound paclitaxel (GnP) are recommended for the first-line treatment of patients with advanced pancreatic cancer. The purpose of this study was to evaluate the efficacy of gemcitabine-based second-line therapies in patients whose disease progressed on FOLFIRINOX.

Method: Patients diagnosed with advanced pancreatic cancer in 7 tertiary hospitals in Turkey were included.

Efficacy and safety of folfiri plus aflibercept in second-line treatment of metastatic colorectal cancer: Real-life data from Turkish oncology group.

Aims: The addition of aflibercept to the fluorouracil and irinotecan (FOLFIRI) regimen significantly improved clinical outcomes in patients with metastatic colorectal cancer (CRC) previously treated with oxaliplatin. We aimed to investigate the efficacy and safety of second-line FOLFIRI and aflibercept combination in patients with metastatic CRC in real-life experience.

Materials And Methods: Four hundred and thirty-three patients who treated with FOLFIRI and aflibercept in the second-line were included in the study.

Prognostic factors of perioperative FLOT regimen in operable gastric and gastroesophageal junction tumors: real-life data (Turkish Oncology Group).

Background: Perioperative FLOT regimen is a standard of care in locally advanced operable gastric and GEJ adenocarcinoma. We aimed to determine the efficacy, prognostic factors of perioperative FLOT chemotherapy in real-life gastric and GEJ tumors.

Methods: The data of patients who were treated with perioperative FLOT chemotherapy were retrospectively analyzed from 34 different oncology centers in Turkey.

The relationship between adjuvant chemotherapy and thiol-disulfide compounds.

Aim: Thiols are the organic compounds of the antioxidant system. There is limited data in the literature concerning chemotherapy (CT) in cancer and thiol balance. In this study, we aimed to evaluate the possible changes of thiol/disulfide levels with the recurrent CT cycles and type of cancer.

The effect of EML4-ALK break-apart ratio on crizotinib outcomes in non-small cell lung cancer harboring EML4-ALK rearrangement.

Purpose: Anaplastic lymphoma kinase (ALK) gene rearrangement exists in approximately 3-7% of non-small cell lung cancer (NSCLC) and more than 15% split or isolated red signals among 50 tumor nuclei scored in the FISH analysis defines as ALK-positive. The previous studies showed that the high EGFR mutational load related to better outcomes in EGFR mutant NSCLC. Therefore, we aimed to investigate the effect of the ALK break-apart ratio on treatment outcome in metastatic ALK-positive NSCLC.

Real-life comparison of the afatinib and first-generation tyrosine kinase inhibitors in nonsmall cell lung cancer harboring EGFR exon 19 deletion: a Turk Oncology Group (TOG) study.

Background: The new second-generation tyrosine kinase inhibitors (TKIs) have superior survival outcome and worse toxicity profile when compared with first-generation TKIs according to the results of clinical trials. However, there are limited studies that investigate the efficacy and safety of the new generation TKIs in real-world patients. Thus, we aimed to compare the efficacy and safety of the afatinib, an irreversible inhibitor of ErbB family receptor, and first-generation TKIs in real-world patients.

Clinical features and outcomes of COVID-19 in patients with solid tumors: Turkish National Registry Data.

We present demographic, clinical, laboratory characteristics and outcomes of the patients with solid malignancies and novel coronavirus disease (COVID-19) collected from the National COVID-19 Registry of Turkey. A total of 1523 patients with a current or past diagnosis of solid tumors and diagnosed with COVID-19 (confirmed with PCR) between 11 March and 20 May 2020 were included. The primary outcome was 30-day mortality.

FDG Hepatic Superscan Due to Metastatic Infiltration of Prostate Cancer.

A 69-year-old man with prostate cancer presented to the hospital with 2 weeks' history of fever, abdominal distension, and fatigue. Laboratory findings showed signs of acute liver failure, and marked elevation of lactate dehydrogenase and tumor marker levels. Abdominal CT showed hepatomegaly with multiple hypodense lesions in both lobes, suggesting metastases.

Prognostic effect of red cell distribution width-to-platelet ratio in colorectal cancer according to tumor stage and localization.

Introduction: Colorectal cancer (CRC) is one of the most common cancers worldwide and survival is still approximately 24 months. Recently, importance of the molecular features, tumor localization, and also inflammatory status is increased, and most of these entities can be used as a predictive marker for colon tumor. However, since most of these tests are expensive and unachievable, there is a need for new prognostic and predictive markers that can be used easily and are inexpensive.

Radiotherapy concurrent with weekly gemcitabine after transurethral tumor resection in muscle ınvasive bladder cancer.

Objective: In this report, we determined the efficacy and the toxicity of low dose weekly gemcitabine with radiotherapy, in medically unfit or refused surgery muscle-invasive bladder cancer (BC) patients.

Materials And Methods: From 2008 to 2012, 15 patients were included into the retrospective analysis. Weekly gemcitabine was administered at a rate of 50 mg/m(2) with a median dose of 63 Gy radiotherapy.

Thrombotic thrombocytopenic purpura following salvage chemotherapy with paclitaxel, ifosfamide and cisplatin in a patient with a refractory germ cell tumor: A case report and review of the literature.

Thrombotic thrombocytopenic purpura (TTP) is a rare form of thrombotic microangiopathy that is characterized by microvascular thrombosis, thrombocytopenia, hemolysis and end organ damage. An extensive variety of drugs, including certain chemotherapeutic agents, have been associated with TTP. However, paclitaxel, cisplatin and ifosfamide regimen (TIP)-induced TTP has not previously been described.

Medication errors in chemotherapy preparation and administration: a survey conducted among oncology nurses in Turkey.
