Article Abstract

The gut microbiota has emerged as a key modulator of cancer treatment responses in terms of both efficacy and toxicity. This effect is clearly mediated by processes impacting the activation and modulation of immune responses. More recently, the ability to regulate chemotherapeutic drug metabolism has also emerged as a key driver of response, although the direct mechanisms have yet to be fully elucidated. Through fermentation, the gut microbiota can produce several types of metabolites, including short-chain fatty acids (SCFAs). SCFAs play an important role in maintaining epithelial barrier functions and intestinal homeostasis, with recent work suggesting that SCFAs can modulate response to cancer treatments and influence both anti-tumor immune response and inflammatory-related side effects. In this review, we will discuss the importance of SCFAs and their implications for cancer treatment response and toxicities.

Background: Robotic single-port transvaginal natural orifice transluminal endoscopic surgery (RSP-vNOTES) is an emerging minimally invasive approach that combines the advantages of robotic surgery with scarless transvaginal access. Its application in gynecologic oncology remains limited, particularly for omentectomy during ovarian cancer staging.

Methods: We present the case of a 45-year-old woman with an ovarian granulosa cell tumor (GCT) who underwent supplemental staging surgery following unilateral oophorectomy.

Introduction: Despite high coverage of routine childhood vaccines, uptake of the human papillomavirus (HPV) vaccine in the Pacific Island nation of Tonga has been slow. Culturally appropriate communication resources on the importance, safety, and effectiveness of the HPV vaccine are critical to support acceptance and uptake. To develop these resources, it is important to understand what people want to know.

Purpose: To determine the real-world incidence and predictive factors for venous and arterial thromboembolic events (VTE/AT) in ovarian cancer patients treated with poly-(ADP-ribose) polymerase inhibitors (iPARP).

Methods/patients: A multicenter retrospective study involving 329 ovarian cancer patients who initiated iPARP treatment between January 2015 and December 2022. The primary outcome was the incidence of VTE/AT.

Background: Immune checkpoint inhibitors (ICIs) play a pivotal role in the treatment of advanced gastric cancer (GC). However, the biomarkers used to predict ICI efficacy are limited due to their reliance on single or static tumor characteristics. This study aims to develop a machine learning (ML) model that incorporates dynamic changes in clinlabomics data to optimize the predictive accuracy of ICI efficacy.

Introduction: Pituitary adenomas (PAs) are generally benign neoplasms, though in rare cases may exhibit aggressive behavior. In 2024, the PANOMEN-3 workshop released a new clinical-pathological classification. The objective of this study was to examine the potential of the PANOMEN-3 classification to predict prognosis of PAs and guide treatment in our single center cohort of patients with PAs.
