Post-operative serum CEA predicts prognosis in HR-positive/HER2-negative early breast cancer.

Background: The prognostic role of preoperative carcinoembryonic antigen (CEA) in breast cancer is recognized, but the impact of postoperative CEA levels on survival in early breast cancer is uncertain.

Research Design And Methods: We conducted a retrospective study of 921 non-metastatic breast cancer patients treated at anonymized. Patients were categorized as normal (CEA ≤3 µg/L) or elevated (CEA >3 µg/L).

Prognostic Significance of Pan-Immune-Inflammation Value in Patients with HER2-Positive Metastatic Breast Cancer Treated with Trastuzumab Emtansine.

Trastuzumab emtansine (T-DM1) is a mainstay therapy for HER2-positive metastatic breast cancer (mBC). However, identifying patients who will benefit most remains a challenge due to the lack of reliable biomarkers. The recently developed pan-immune-inflammation value (PIV), a novel immune-inflammation marker, could aid in this regard, considering the immunomodulatory effects of T-DM1.

The impact of human epidermal growth factor receptor-2 (low) status on the efficacy of first line cyclin-dependent kinase 4/6 inhibitors in advanced breast cancer.

The fact that the human epidermal growth factor receptor 2 (HER2)-low group, historically classified as HER2 negative in breast cancer histology, benefited from HER2-targeted treatments similarly to the HER2-positive group indicates that this group has a distinct histology from the HER2-0 group. The effectiveness of cyclin-dependent kinase 4/6 inhibitors, which are the standard first-line treatment for hormone receptor-positive, HER2-negative advanced breast cancer, in this newly defined histological subgroup remains a topic of debate. In our study, we examined the impact of HER2 status on the efficacy of CDK4/6 inhibitors.

Impact of opioid analgesics on survival in cancer patients receiving immune checkpoint inhibitors.

Purpose: This study aimed to assess the effects of concurrent opioid analgesic (OA) use with immune checkpoint inhibitors (ICIs) on progression-free survival (PFS) and overall survival (OS).

Methods: In this observational retrospective study, we included advanced cancer patients who received ICIs at Hacettepe University Hospital's Department of Medical Oncology between June 2018 and January 2023.

Results: Our study included 375 recurrent or metastatic cancer patients treated with ICIs in the first, second line, or beyond.

Twelve-month progression-free survival with sotorasib and panitumumab in KRAS G12C mutant metastatic colorectal cancer.

Colorectal cancer (CRC) ranks third in global cancer prevalence, with 40% presenting as metastatic colorectal cancer (mCRC). KRAS mutations in mCRC patients confer resistance to anti-EGFR treatments. Promising inhibitors such as sotorasib and adagrasib targeting KRASG12C mutations have demonstrated efficacy.

The Efficacy of Immune Checkpoint Inhibitors in Microsatellite Stable Colorectal Cancer: A Systematic Review.

The use of immune checkpoint inhibitors (ICIs) has revolutionized cancer care, particularly in immune-inflamed tumors and tumors with a high mutational burden, like microsatellite instable colorectal cancer (CRC). However, their effectiveness in microsatellite stable (MSS) CRC is limited. This systematic review aims to evaluate the efficacy of ICIs in MSS CRC and explore promising combination strategies.

Acute heart failure following pazopanib treatment: a literature review featuring two case reports.

Tyrosine kinase inhibitors (TKIs) have transformed cancer treatment but are associated with cardiovascular toxicity, including heart failure. This review examines the cardiotoxicity of pazopanib, a VEGFR-TKI, through two case reports and explores potential mechanisms. The importance of vigilant clinical monitoring to prevent cardiac dysfunction in cancer patients receiving pazopanib is emphasized.

The incidence and risk factors for acute kidney injury in patients treated with immune checkpoint inhibitors.

Recent observational studies reported acute kidney injury (AKI) events in over 10% of the patients treated with immune checkpoint inhibitors (ICIs). However, these studies included patients treated in high-resource settings and earlier lines. Therefore, we aimed to assess the AKI rates and predisposing factors in ICI-treated patients from a limited resource setting.

The association between albumin-globulin ratio (AGR) and survival in patients treated with immune checkpoint inhibitors.

Background: The albumin-globulin ratio (AGR) could be a prognostic biomarker in patients with cancer, although the data is limited in patients treated with immune-checkpoint inhibitors (ICIs).

Objectives: We aimed to evaluate the association between AGR and survival in ICI-treated patients.

Methods: The data of 212 advanced-stage patients were retrospectively evaluated in this cohort study.

The burden of polypharmacy and drug-drug interactions in older cancer patients treated with immunotherapy.

Introduction: Polypharmacy is a common problem in older cancer patients, although the data about polypharmacy and potentially inappropriate prescription practices is limited in patients treated with immune checkpoint inhibitors (ICIs). Therefore, we aimed to evaluate the polypharmacy frequency and drug-drug interactions in older cancer patients (≥65 years) treated with ICIs.

Methods: A total of 70 geriatric patients with advanced cancer were included.
