Article Synopsis
- Environmental stressors during pregnancy, such as pollutants and metals, can affect DNA methylation, influencing the risk of chronic diseases later in life.
- The study investigated how these exposures relate to DNA methylation in placental, maternal, and neonatal cells by analyzing 28 mother-infant pairs and utilizing artificial neural networks.
- Results indicated that factors like suboptimal birth weight and maternal stress during pregnancy are linked to specific DNA methylation changes, suggesting that maternal exposure to environmental toxins can have significant implications for fetal development and health.*
Background/aim: The expression of the cyclin-dependent kinase inhibitor p16 correlates with the presence of human papillomavirus. The purpose of this investigation was to assess the prognostic relevance of p16 expression in patients with vulvar squamous cell carcinoma (VSCC) treated with radical surgery followed by adjuvant (chemo) radiation in selected cases.
Patients And Methods: Seventy-eight patients were analyzed retrospectively.
Background/aim: The aim of the study was to correlate the expression of mismatch repairs proteins (MMR), programmed-death-ligand1 (PDL-1), and estro-progestinic receptors (ER/PgR) in tissue samples from a series of cervical adenocarcinoma (ADC) patients with their clinicopathological features.
Materials And Methods: Thirty-nine ADC specimens were retrospectively retrieved from the Division of Pathology of the University Hospital of Pisa from 2015 to 2021. Histological subtype, grade (G), Silva pattern, presence of lymph vascular space invasion (LVI), and perineural invasion (PNI) were annotated.
Lymph-vascular Space Involvement and/or p53 Overexpression Correlated With the Clinical Outcome of Early-stage Endometrial Cancer Patients Treated With Adjuvant Vaginal Brachytherapy.

Background/aim: The majority of patients with endometrial cancer (EC) are diagnosed at an early stage and undergo primary surgery, followed by observation or adjuvant therapy according to risk factors on surgical samples. The objective of this study was to assess the correlation between a risk profile represented by the presence of substantial lymph-vascular space involvement (LVSI) and/or p53 overexpression and the clinical outcome of patients with early-stage endometrial cancer (EC) who received adjuvant vaginal brachytherapy (BT).
Patients And Methods: This investigation assessed 79 patients who underwent hysterectomy, bilateral salpingo-oophorectomy, and pelvic and/o aortic lymphadenectomy or sentinel lymph node biopsy followed by hypofractionated (HDR)-vaginal BT, using 192Ir source, for stage I-II endometrioid (n=70) or non-endometrioid (n=9) EC.
Background/aim: The aims of the study were: i) to assess the incidence of perineural invasion (PNI) in squamous cell carcinoma of the vulva and ii) to correlate PNI with common pathological prognostic variables and clinical outcome of patients.
Patients And Methods: The hospital records of 64 patients with vulvar squamous cell carcinoma who underwent primary radical surgery were reviewed.
Results: PNI was significantly related to stage (p=0.
