Article Synopsis
  • The study aimed to evaluate how the combination of HALP score and TTCR score influences overall survival (OS) and progression-free survival (PFS) in prostate cancer patients who developed castration resistance.
  • A total of 152 metastatic prostate cancer patients were analyzed, categorized based on median cut-off values for HALP (30.83 months) and TTCR (16.1 months), resulting in three risk stratification groups.
  • The findings indicated that lower HALP scores and shorter TTCR were linked to significantly worse PFS, and that combining these factors improved predictions for OS and PFS in patients with metastatic castration-resistant prostate cancer (mCRPC).

We evaluated the incidence, clinicopathological features, prognostic factors, progression-free survival (PFS) and overall survival (OS) of patients with gastric cancer and bone metastases. The medical records of 110 patients with bone metastases were retrospectively analyzed. In our study, the incidence of bone metastases was 3.

The aim of our study was to evaluate the incidence of KRAS/NRAS and BRAF mutations, analyze molecular patterns, and investigate associations with clinical parameters of these mutations in CRC KRAS/NRAS and BRAF mutations analyzed by next-generation sequencing. The detection rates of these mutations and patients' demographics were recorded and the relationship between them was evaluated using the chi-square test. KRAS mutation was detected in 332 of 694 patients, while the mutation rates in KRAS exons 2/3 and 4 were 39.

Metastatic castration-resistant prostate cancer (mCRPC) remains a challenging condition to treat despite recent advancements. This retrospective study aimed to assess the activity and tolerability of Lutetium-177 (Lu-177) PSMA-617 radioligand therapy (RLT) in mCRPC patients across multiple cancer centers in Turkey. The study included 165 patients who received at least one cycle of Lu-177 PSMA-617 RLT, with the majority having bone metastases and undergone prior treatments.

Aim: In this study, we aimed to analyze the effect of prognostic nutritional index and neutrophile lymphocyte ratio on the overall survival (OS) in patients treated with regorafenib.

Materials And Methods: Metastatic colorectal cancer (CRC) patients who treated with regorafenib between 2016 and 2020 in a single center were evaluated retrospectively. ROC analysis was used for neutrophile lymphocyte ratio (NLR's) and prognostic nutritional index (PNI's) optimum cut-off value.

Background: In our study, we aimed to investigate the protective effects of Saccharomyces boulardii on abemaciclib-induced diarrhea model, which is a commonly used drug in breast cancer.

Methods: Thirty rats were divided into 3 groups as control (Group 1), abemaciclib (Group 2), and abemaciclib + Saccharomyces boulardii (Group 3) groups. The clinical status, body weight, and defecation status were monitored daily.

Background: There is no standard treatment recommended at category 1 level in international guidelines for subsequent therapy after cyclin-dependent kinase 4/6 inhibitor (CDK4/6) based therapy. We aimed to evaluate which subsequent treatment oncologists prefer in patients with disease progression under CDKi. In addition, we aimed to show the effectiveness of systemic treatments after CDKi and whether there is a survival difference between hormonal treatments (monotherapy vs.

Sarcomatoid renal cell carcinoma (sRCC) is a rare variant of renal cell carcinoma (RCC) and is associated with a poor prognosis. We reviewed the outcomes of patients from oncology centers in Turkey. Our aim is to share our real-life experience and to contribute to the literature.

The case of a patient who developed recurrent delayed immune-related pneumonitis (checkpoint inhibitor pneumonitis [CIP]) after immune checkpoint inhibitor (ICI) therapy for advanced osteosarcoma treatment is presented. A 25-year-old female patient with metastatic osteosarcoma was treated with atezolizumab. Grade 2 pneumonitis developed three times in the first two years.

Purpose: To demonstrate whether early changes in systemic inflammatory markers are related with pazopanib treatment response in soft tissue sarcoma and renal cell carcinoma.

Methods: Forty-one patients with metastatic clear cell renal carcinoma (mRCC) (n=22) and advanced stage soft tissue sarcoma (STS) (n=19) were assessed. Systemic inflammatory markers such as neutrophils, lymphocytes, c-reactive protein (CRP), mean platelet volume (MPV), lactate dehydrogenase (LDH) and neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) at both baseline and 1-month of pazopanib treatment were obtained and their relation with the first radiological response about 3-months later after pazopanib treatment was evaluated.

Purpose: We aimed to identify the prognostic and predictive values of post-treatment prognostic nutritional index (PNI) and PNI dynamics in nasopharyngeal cancer patients (NPC) in this study.

Methods: One hundred seven non-metastatic NPC patients were included. PNI was calculated by using the following formula: [10 × serum albumin value (gr/dL)] + [0.

Introduction: Osimertinib, an irreversible third-generation EGFR-TKI, is the standard of care for second-line treatment of T790M-mutant advanced NSCLC patients whose disease progressed after first-line EGFR-TKI therapy. In this multicenter study, we aimed to determine the real-life efficacy and safety of Osimertinib in pretreated advanced NSCLC patients with T790M mutation.

Materials And Methods: This retrospective trial included advanced T790M-mutant pretreated NSCLC patients who received Osimertinib from 24 different centers in Turkey.

Background: Transverse colon cancer (TCC) is a rare condition that accounts for 10% of all colon cancers. TCC was accepted more likely right-sided colon cancers. We aimed to investigate whether TCC differs from other colon tumors by using clinical, pathological, and molecular prognostic factors known to be important in colon cancer and if it differs in its own anatomical structure.

Purpose: We aimed to assess whether skeletal muscle loss during EGFR thyrosine kinase inhibitor therapy of advance non-small cell lung cancer patients is an independent prognostic factor for progression-free survival (PFS) and overal survival (OS).

Methods: A total of 45 patients who had computed tomography images were retrospectively evaluated at the diagnosis and during the treatment period before progression occurs.

Results: During treatment 19 patients (42.

Objective: To evaluate clinical and demographic characteristics and the results of cytotoxic treatments of , , and next-generation sequencing (NGS) panel negative patients.

Methods: NGS data of 1264 patients with non-small cell lung cancer were retrospectively evaluated. Among these patients, the mutation distributions of 1081 patients with metastatic lung adenocarcinoma were analyzed.
