Abstract Most ovarian cancers are infiltrated by prognostically relevant activated T cells 1–3 , yet exhibit low response rates to immune checkpoint inhibitors 4 . Memory B cell and plasma infiltrates have previously been associated with better outcomes in cancer 5,6 but the nature functional relevance of these responses controversial. Here, using 3 independent cohorts that total comprise 534 patients high-grade serous cancer, we show robust, protective humoral dominated production...

<h3>Importance</h3> Breastfeeding has been associated with a reduced risk of epithelial ovarian cancer in multiple studies, but others showed no association. Whether reduction extends beyond that provided by pregnancy alone or differs histotype is unclear. Furthermore, the observed associations between duration and timing breastfeeding have inconsistent. <h3>Objective</h3> To determine association (ie, ever/never, duration, timing) overall histotype. <h3>Design, Setting, Participants</h3> A...

Abstract Purpose: A major challenge in platinum-based cancer therapy is the clinical management of chemoresistant tumors, which have a largely unknown pathogenesis at level epigenetic regulation. Experimental Design: We evaluated potential using global loss 5-hydroxymethylcytosine (5-hmC) levels as novel diagnostic and prognostic marker to better assess chemotherapy response outcome high-grade serous tumors (HGSOC), most common deadliest subtype ovarian cancer. Furthermore, we identified...

To assess the effect of dienogest on recurrence ovarian endometriomas and severity pain after laparoscopic surgery, a retrospective study 81 patients was performed at three institutions in Osaka, Japan. Patients had six-month minimum follow-up surgery for between June 2012 August 2014. who chose to receive 2 mg daily those were managed expectantly postoperatively included. Recurrence defined as presence more than cm. A visual analog scale (VAS) used score intensity pelvic pain. The...

Abstract Introduction Primary Sjögren's syndrome (pSS) is a chronic autoimmune disorder affecting salivary and lacrimal glands, while endometriosis involves uterine‐like tissue growth outside the uterus, causing pelvic pain infertility. Investigating their intricate relationship using real‐world data crucial due to limited research on connection. Material Methods This population‐based cohort study included patients with controls without endometriosis. Propensity score matching was used...

Introduction Over four million women in the US alone have been diagnosed with endometriosis. For those living this disease, surgery and hormonal treatment reduce associated pelvic pain some, while others continue to experience life impacting pain. Therefore, identification of accessible cost-effective methods reduction compliment current is urgently needed.

Abstract Background: Ovarian high-grade serous carcinomas (HGSC) comprise four distinct molecular subtypes based on mRNA expression patterns, with differential survival. Understanding risk factor associations is important to elucidate the etiology of HGSC. We investigated between different epidemiologic factors and HGSC subtypes.

Background Conditioned pain modulation (CPM) is considered a human proxy for descending inhibitory pathways. However, there wide variation in the CPM response described literature and ongoing debate about its utility. Methods Here we explored women with ( n = 59) without 26) chronic pelvic (CPP), aiming to determine magnitude of effect factors influencing variability response. Results Using pressure threshold test stimulus ischaemic cuff conditioning (CS), found no significant difference...

Summary: Biological characteristics of tumors are heterogeneous, forming spectra in terms several factors such as age at onset, anatomic spatial localization, tumor subtyping, and the degree aggressiveness (encompassing a neoplastic property spectrum). Instead blindly using dichotomized approaches, application multicategorical continuous analysis approaches to detailed cancer spectrum data can contribute better understanding etiology cancer, ultimately leading effective prevention precision...
