Detection of TP53 Clonal Variants in Papanicolaou Test Samples Collected up to 6 Years Prior to High-Grade Serous Epithelial Ovarian Cancer Diagnosis.

Importance: The low 5-year survival rate of women with high-grade serous epithelial ovarian cancer (HGS-EOC) is related to its late diagnosis; thus, improvement in diagnosis constitutes a crucial step to increase the curability of this disease.

Objective: To determine whether the presence of the clonal pathogenic TP53 variant detected in matched primary tumor biopsies can be identified in DNA purified from Papanicolaou test samples collected from women with HGS-EOC years before the diagnosis.

Design, Setting, And Participants: This cohort study was conducted among a single-center cohort of women with histologically confirmed diagnosis of HGS-EOC recruited at San Gerardo Hospital, Monza, Italy, from October 15, 2015, to January 4, 2019.

Radiomics of the primary tumour as a tool to improve F-FDG-PET sensitivity in detecting nodal metastases in endometrial cancer.

Background: A radiomic approach was applied in 18F-FDG PET endometrial cancer, to investigate if imaging features computed on the primary tumour could improve sensitivity in nodal metastases detection. One hundred fifteen women with histologically proven endometrial cancer who underwent preoperative 18F-FDG PET/CT were retrospectively considered. SUV, MTV, TLG, geometrical shape, histograms and texture features were computed inside tumour contours.

Presence and passage dependent loss of biochemical M3 muscarinic receptor function in human detrusor cultured smooth muscle cells.

Purpose: We explored morphological and biochemical aspects of human detrusor cells in culture as a tool for investigating the physiological mechanisms underlying bladder function and disturbances.

Materials And Methods: Primary cultures of smooth muscle cells were derived from human bladder specimens of patients with an average age of 70 years undergoing cystectomy. Cultured cells were investigated by morphological, immunocytochemical and Western blot analysis.

Prejunctional muscarinic inhibitory control of acetylcholine release in the human isolated detrusor: involvement of the M4 receptor subtype.

1. Experiments were carried out in human detrusor strips to characterize muscarinic receptor subtypes involved in the prejunctional regulation of acetylcholine (ACh) release from cholinergic nerve terminals, and in the postjunctional smooth muscle contractile response. 2.

[Interstitial cystitis: medical treatment].

Interstitial cystitis is a chronic disease of the bladder and its etiology is still unknown. In this article we treat the different approaches to this disease, supported by the fact that a clear therapeutic protocol doesn't exist.
