Materials And Methods: Gastric cancer patients over 18 years of age who were admitted to our clinic between 2000 and 2019 and underwent primary curative surgery and R0 resection were included in the study.

The Naples prognostic score in esophagus cancer: Prognostic and beyond.

Objectives: The role of inflammation in tumor biology has been better understood over time. The utility of the Naples prognostic score (NPS), which is a novel inflammation-based marker, was shown in esophageal carcinoma (EC) patients treated with surgery. We herein presented the prognostic and predictive value of NPS in EC patients treated with upfront chemoradiotherapy (CRT).

Evaluation of Predictive and Prognostic Importance of Lung Immune Prognostic Index in Locally Advanced Rectal Cancer Patients Treated With Neoadjuvant Chemoradiotherapy.

Objective: The systemic inflammatory response (SIR) is known as an important factor associated with tumorigenesis and tumor progression, and can be reflected by inflammatory markers. One of the markers that reflect this is the lung immune prognostic index (LIPI). It is based on a derived neutrophil-to-lymphocyte ratio (dNLR) and lactate dehydrogenase (LDH) level.

Prognostic significance of mucinous histology in left‑sided metastatic colorectal cancers with wild‑type RAS and evaluation of backbone chemotherapy regimens.

Mucinous colorectal adenocarcinoma (MCAC) is a distinct subtype of colorectal carcinoma (CRC). The prognostic and predictive significance of mucinous histology remains controversial. It was aimed to investigate the prognostic and/or predictive role of mucinous histology in left-sided metastatic CRC (mCRC) with wild-type RAS.

Prognostic value of Gustave Roussy immune score in operable pancreatic adenocarcinoma.

Background: The Gustave Roussy immune score (GRIm score) is a laboratory index developed to predict survival in nonsmall cell lung cancer patients undergoing immunotherapy and has shown that the pretreatment value is an independent prognostic factor for survival. In this study, we aimed to determine prognostic significance of GRIm score for pancreatic adenocarcinoma that have not been determined in the literature for pancreatic cancer before. The reason for choosing this scoring is to show that the immune scoring system works as a prognostic marker in pancreatic cancer known as immune-desert tumor via immune properties of microenvironment.

Age-adjusted Charlson Comorbidity Index is a valuable prognostic tool in operable soft tissue sarcoma of trunk and extremities.

Background: Advanced age and presence of comorbidities affect prognosis and treatment decisions in patients with soft tissue sarcoma (STS).

We aimed to investigate the role of the CONUT Score in EC patients treated with chemoradiotherapy (CRT).

Role of baseline Ga-PSMA PET/CT-derived whole-body volumetric parameters in predicting survival outcomes of metastatic castration-resistant prostate cancer patients receiving first-line treatment.

Objective: We aimed to evaluate whether baseline Ga-PSMA PET/CT-derived whole-body volumetric parameters could be used as predictive biomarkers for survival in metastatic castration-resistant prostate cancer (mCRPC) patients receiving first-line treatment.

Materials And Methods: This retrospective study included 54 mCRPC patients, who underwent baseline Ga-PSMA PET/CT imaging within 1 month before starting first-line treatment. Pre-treatment prostate-specific antigen (PSA) levels and treatments were recorded.

Predictive value of F-FDG PET/CT indices on extensive residual cancer burden in breast cancer patients treated with neoadjuvant chemotherapy.

Aim: We investigated the correlation between F-FDG PET/CT indices and pathological response in breast cancer treated with neoadjuvant chemotherapy (NACT) which was scored with Residual Cancer Burden (RCB) system after surgery. Our aim is to detect extensive residual cancer burden earlier by using PET/CT indices.

Methods: Characteristics of patients were retrieved retrospectively.

Dynamic changes in systemic immune-inflammation index predict pathological tumor response and overall survival in patients with gastric or gastroesophageal junction cancer receiving neoadjuvant chemotherapy.

Aim: Systemic inflammation has been associated with chemoresistance and prognosis in solid tumors. Systemic immune-inflammation index (SII) is a novel marker derived from complete blood count. We investigated whether differences between SIIs measured before and after neoadjuvant chemotherapy (NACT) are associated with tumor regression grade (TRG) and survival in gastric and gastroesophageal junction (GEJ) cancer patients.

Impact of prognostic nutritional index on survival in recurrent glioblastoma.

Background: Primary brain tumors are relatively rare malignancy, with high-grade gliomas (glioblastoma multiforme and anaplastic gliomas) are the most common types. We aimed to evaluate the prognostic value of Prognostic Nutritional Index (PNI), which is calculated by lymphocyte count and albumin, in recurrent glioblastoma patients treated with systemic treatment.

Methods: Data of 64 patients with recurrent glioblastoma who received systemic treatment and followed in our clinic between 2012 and 2018 was retrospectively collected and analyzed.

Prognostic Value of Tissue-Resident Memory T Cells and Tumor Microenvironmental Features in Resected Pancreatic Adenocarcinoma.

Background: Pancreatic ductal adenocarcinoma differs from other solid tumors with its unique immunosuppressive microenvironment and non-immunogenic feature. There are not many studies in the literature investigating the effect of these features on prognosis.

Aims: To investigate the prognostic value of tissue-resident memory T cells, tumor microenvironment features, and tumor-associated immune cells in resected pancreatic ductal adenocarcinomas.

Current and future immunotherapy approaches in ovarian cancer.

Ovarian cancer (OC) is the major cause of gynecologic cancer deaths and relapse is common despite advances in surgery and systemic chemotherapy. Therefore, novel treatments are required to improve long-term outcomes of the disease. Efficacy of immunotherapy was demonstrated in many tumors and it has been since incorporated into clinical practice for them.

Rechallenge with dabrafenib plus trametinib in anaplastic thyroid cancer: A case report and review of literature.

Introduction: Anaplastic thyroid carcinoma (ATC) is a highly aggressive, undifferentiated rare tumor. Median overall survival is usually between 8 and10 months, with a 1-year survival rate of 20%.

Is insulin resistance a predictor for complete response in breast cancer patients who underwent neoadjuvant treatment?

Purpose: Neoadjuvant chemotherapy is the standard front-line treatment modality in locally advanced breast cancer. Achieving pathological complete response (pCR) is a significant prognostic factor for prolonged disease-free and overall survival. Insulin resistance is defined as a pathological condition in which insulin effect is impaired in peripheral target tissues such as the skeletal muscle, liver, and adipose tissue.

Differences in PET/CT standardized uptake values involvement and survival compared to histologic subtypes of lung adenocarcinoma.

Purpose: Lung adenocarcinoma is histologically diverse but has distinct histologic growth patterns. There is no consensus on the clinical benefit of this histologic model. We aimed to evaluate the differences in the distribution of the preoperative primary tumor positron emission tomography (PET)/computed tomography (CT) standardized uptake values (SUVs) and survival in the lung adenocarcinoma subtypes.

We aimed to evaluate the prognostic value of modified Glasgow Prognostic Score (mGPS), which is combination of C-reactive protein (CRP) and albumin, in recurrent high-grade glioma patients treated with systemic treatment.

Patients And Methods: Data of 85 patients with recurrent high-grade glioma who received systemic treatment and followed in our clinic between 2012 and 2018 was retrospectively collected and analyzed.

QT interval prolongation related to afatinib treatment in a patient with metastatic non-small-cell lung cancer.

Afatinib improves survival in metastatic non-small-cell lung cancer driven by activating epidermal growth factor receptor mutations. QT interval prolongation is a possible side effect of targeted anticancer drugs, but this has not been reported before with afatinib. We report a case of metastatic pulmonary adenocarcinoma with epidermal growth factor receptor exon 19 deletion who was treated with first-line afatinib.
