Roles of metabolic tumor volume and total lesion glycolysis on 18F-FDG PET/CT, CA19-9 levels, and complete blood count parameters in predicting survival in patients with unresectable or metastatic pancreatic cancer.

Aim: In this study, we aimed to investigate the roles of volume based 18F-FDG PET/CT parameters, CA19-9 levels, and complete blood count parameters in predicting survival in patients with unresectable and/or metastatic pancreatic ductal adenocarcinoma.

Materials And Method: Fifty-seven pancreatic cancer patients who were followed in University of Health Sciences Gazi Yasargil Training and Research Hospital between January 2017 and June 2020, declined surgical treatment and/or radiation therapy or had medically inoperable, unresectable, or metastatic disease, and received chemotherapy were included in the study. 18F-FDG PET/CT images of patients were evaluated and calculated metabolic tumor volume (MTV) and total lesion glycolysis (TLG) parameters were compared with CA19-9 levels and complete blood count parameters.

Comparison of 18F-FDG PET/CT and 68Ga-FAPI-04 PET/CT in the staging and restaging of gastric adenocarcinoma.

Objective: In this study, we aimed to evaluate the diagnostic sensitivities of 68Ga-FAPI-04 PET/CT and 18F-FDG PET/CT in the primary tumor, and nodal, peritoneal and distant organ metastases of primary and recurrent gastric adenocarcinoma (GAc) with patient and lesion-based comparison.

Materials And Method: Twenty-one patients with histopathologically proven newly diagnosed or recurrent GAc who underwent 18F-FDG and 68Ga-FAPI-04 imaging were included in the study. Both imaging techniques were evaluated visually according to the intensity of organ-based uptake.

Nivolumab-Related Dry Mouth and Dry Eye: Cross-Sectional Study.

To evaluate ICIs related dry eye and dry mouth in nivolumab therapy, 24 patients receiving nivolumab (group 1), 30 patients in remission without treatment for 6 months (group 2), 30 healthy participants (group 3) were cross-sectionally examined. Schirmer's 1, 2, TSH blood tests, serological analysis, salivary flow scintigraphy and minor-salivary gland biopsy were performed. Schirmer's tests were performed with anesthetic (1) and without anesthetic (2).

The role of inflammatory parameters in predicting disease recurrence in patients with stage IIA colon cancer with no high-risk features.

Objective: We aimed to investigate the roles of inflammatory parameters, including neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), lymphocyte/monocyte ratio (LMR), and C-reactive protein/albumin ratio (CAR), in predicting disease recurrence in patients with stage IIA (T3N0M0) high microsatellite instability and microsatellite-stable colon cancer who had no risk factors associated with relapse.

Materials And Methods: We evaluated 155 patients with colon cancer followed in 3 hospitals in Turkey between February 2009 and March 2020. These patients had stage IIA disease and had no risk factors associated with relapse.

Role of Ga-PSMA PET/CT parameters in treatment evaluation and survival prediction in prostate cancer patients compared with biochemical response assessment.

Objective: In this study, we aimed to evaluate the concordance of biochemical treatment response with gallium-68-prostate specific membrane antigen (Ga-PSMA) positron emission tomography/computed tomography (PET/CT) treatment response in prostate cancer (PCa) and investigate their prognostic effects on survival.

Materials And Methods: One hundred and fifty-onepatients with PCa, who underwent Ga-PSMA PET/CT imaging in our clinic between May 2016 and December 2019, were on treatment, and had pre-treatment and post-treatment imaging studies were included in our study. The treatment patients received and prostate-specific antigen (PSA) levels at the time of PET/CT imaging were recorded.

Depression and anxiety in cancer patients before and during the SARS-CoV-2 pandemic: association with treatment delays.

Purpose: Pandemics can be associated with anxiety and depression in cancer patients who are undergoing treatment. In the present study, we aimed to perform a comparative evaluation of the conditions of cancer patients before and during the severe acute respiratory distress syndrome coronavirus 2 (SARS-CoV-2) pandemic using the Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) to detect the impact of the pandemic on treatment delays that are associated with anxiety and depression in cancer patients. In addition, the effect of public transport use on treatment delays was examined.

Correlations between whole body volumetric parameters of Ga-PSMA PET/CT and biochemical-histopathological parameters in castration-naive and resistant prostate cancer patients.

Objective: To evaluate the relationship between whole body volumetric (Wbv) results of Ga-PSMA PET/CT with biochemical and histopathological parameters.

Methods: One hundred twenty-one prostate cancer patients who underwent Ga-PSMA PET/CT between January 2018 and December 2019 were included. Imaging was conducted for staging upon new diagnosis with moderate- and high-risk disease and for confirming the progression of castration resistance.
