The safety and efficacy of first-line atezolizumab plus bevacizumab in patients with unresectable hepatocellular carcinoma: A multicenter real-world study from Turkey.

The aim of the study was to evaluate the real-world clinical outcomes of atezolizumab and bevacizumab (Atez/Bev) as the initial therapy for advanced hepatocellular carcinoma (HCC). We retrospectively analyzed 65 patients treated with Atez/Bev for advanced HCC from 22 institutions in Turkey between September 2020 and March 2023. Responses were evaluated by RECIST v1.

Real-life comparison of afatinib and erlotinib in non-small cell lung cancer with rare EGFR exon 18 and exon 20 mutations: a Turkish Oncology Group (TOG) study.

Objectives: To compare the survival of first- and second-generation tyrosine kinase inhibitors (TKIs) in patients with rare EGFR exon 18 and exon 20 mutation-positive non-small cell lung cancer (NSCLC).

Materials And Methods: We retrospectively evaluated survival characteristics of 125 patients with EGFR exon 18 and exon 20 mutated NSCLC who received erlotinib or afatinib as first line treatment between 2012 and 2021 from 34 oncology centres. Since exon 20 insertion is associated with TKI resistance, these 18 patients were excluded from the study.

The Relation between Homocysteine Levels in Patients with Acute Coronary Syndrome and Grace Score.

Objectives: This study investigated the correlation between homocysteine levels in patients with Acute Coronary Syndrome and GRACE Score.

Methods: This study included 191 cases -140 Non-ST MI cases and 51 MI with ST-elevation cases in Şişli Etfal Training and Research Hospital Coronary Intensive Care Unit between December 2008 and March 2010. Homocysteine was measured by immulite 2000 device, using kemiluminesans method and competitive immunoassay principle and a kit by DPC was used during the measurement.

Atezolizumab in Patients with Metastatic Urothelial Carcinoma Who Have Progressed After First-line Chemotherapy: Results of Real-life Experiences.

Background: Atezolizumab (ATZ) has demonstrated antitumor activity and manageable safety in previous studies in patients with locally advanced or metastatic platinum-resistant urothelial carcinoma.

Objective: To compare the real-life experience and data of clinical trials on ATZ treatment in metastatic urothelial carcinoma.

Design, Setting, And Participants: Patients with urothelial cancer treated with ATZ after progression on first-line chemotherapy from an expanded access program were retrospectively studied.

The lymph node ratio as an independent prognostic factor for non-metastatic node-positive breast cancer recurrence and mortality.

Purpose: To examine the prognostic value of lymph node ratio (LNR) in pathological nodal (pN) stage breast cancer patients. Also, to analyse additional clinical and pathologic prognostic factors and the impact of LNR among molecular subtypes.

Methods: Among a total of 3088 patients, 1004 women with non-metastatic lymph node-positive breast cancer were analysed.

Clinical Significance of HER2 Overexpression in Gastric and Gastroesophageal Junction Cancers.

Background: In this study, we investigated the rate of human epidermal growth factor receptor 2 (HER2) overexpression in gastric (GC) and gastroesophageal junction cancers (GEJCs) and the relationship with HER2 expression and clinical, pathological parameters and prognosis.

Methods: Surgery or biopsy specimen of 598 (436 males, 162 females) patients with GC or GEJC was evaluated for the presence of HER2 overexpression by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) methods.

Results: HER2 IHC scores were as follows: 418 (69.

A laboratory prognostic index model for patients with advanced non-small cell lung cancer.

Purpose: We aimed to establish a laboratory prognostic index (LPI) in advanced non-small cell lung cancer (NSCLC) patients based on hematologic and biochemical parameters and to analyze the predictive value of LPI on NSCLC survival.

Patients And Methods: The study retrospectively reviewed 462 patients with advanced NSCLC diagnosed between 2000 and 2010 in a single institution. We developed an LPI that included serum levels of white blood cells (WBC), lactate dehydrogenase (LDH), albumin, calcium, and alkaline phosphatase (ALP), based on the results of a Cox regression analysis.

Bone metastasis from gastric cancer: the incidence, clinicopathological features, and influence on survival.

Purpose: To evaluate the incidence, clinicopathological characteristics, treatment outcomes, prognostic factors, and survival of gastric cancer patients with bone metastases.

Materials And Methods: Of 4,617 gastric cancer patients who were treated between 2001 and 2013, 176 patients with bone metastases were analyzed.

Results: The incidence of bone metastasis was 3.

Metaplastic breast carcinoma: case series and review of the literature.

Metaplastic breast carcinoma (MpBC) is a rare disease entity, accounting for less than 1% of all breast carcinomas. Furthermore, it is a heterogenous disease with different subgroups, including malignant epithelial (carcinoma) and stromal (sarcoma) features. Here we evaluated, retrospectively, 14 female MpBC patients admitted to Ankara Oncology Training and Research Hospital between 2005 and 2011.

Association between common risk factors and molecular subtypes in breast cancer patients.

Background: Breast cancer is the most commonly diagnosed cancer in women worldwide and characterized its by molecular and clinical heterogeneity. Gene expression profiling studies have classified breast cancers into five subtypes: luminal A, luminal B, HER-2 overexpressing, basal-like, and normal breast-like. Although clinical differences between subtypes have been well described in the literature, etiologic heterogeneity have not been fully studied.

Risk factors of nasopharyngeal carcinoma in Turkey-an epidemiological survey of the Anatolian Society of Medical Oncology.

Background: Nasopharyngeal carcinoma is a rare disease in most parts of the world with a multifactorial etiology involving an interaction of genetic, viral, environmental and dietary risk factors. This is the first epidemiologic study aimed to evaluate the risk factors of nasopharyngeal carcinoma in the Turkish population.

Methods: We conducted a multicentric, retrospective, case-control study using a standardized questionnaire which captured age, sex, occupation, household type, blood group, dietary habits, smoking, alcohol consumption and oral hygiene.

Primary gastric Hodgkin lymphoma and metachronous early gastric carcinoma: a case report.

Primary Gastric Hodgkin lymphoma is seen very rarely. Primary gastric Hodgkin lymphoma and gastric carcinoma in same patient is very very rare entity. Almost all of the primary gastric lymphoma cases are non-Hodgkin lymphoma type.
