AI Article Synopsis
- Robot-assisted laparoscopic radical prostatectomy is an effective treatment for localized prostate cancer, but patients might still face late recurrence and metastatic spread.
- Peritoneal metastases are a rare type of recurrence, and this text discusses three cases where such metastases occurred after this surgical procedure.
- The authors propose two mechanisms for these metastases: one caused by the surgery itself in patients with less aggressive tumors, and the other due to the natural progression of aggressive tumors, regardless of prior surgery.
Article Abstract
Robot-assisted laparoscopic radical prostatectomy is one of the treatment options for localized prostate cancer, with an excellent disease control rate. However, these patients can experience late disease recurrence with metastatic dissemination. Peritoneal metastases are an uncommon recurrence site. Here, we discuss 3 cases of peritoneal metastases following robot-assisted laparoscopic radical prostatectomy and the mechanisms of peritoneal invasion. Through a literature review and our case reports, we postulate the existence of 2 distinct mechanisms of peritoneal invasion: one being iatrogenic, following a laparoscopic surgery with a well differentiated prostate cancer at a nonadvanced stage of the disease, the other involving the natural course of poor-prognosis tumors, even without surgery.

Matrix metalloproteinases (MMP) have been identified as biomarkers for several diseases, including cancer. The increase in the expression of these enzymes has been related to greater tumor aggressiveness. MMP-26 is expressed constitutively in the endometrium and some cancer cells of epithelial origin.

This article aims to identify the relationship between material deprivation and mortality from breast, cervical, and prostate neoplasms in the Brazilian adult population and the relationship between ethnicity/skin color and material deprivation. This cross-sectional ecological study calculated the mean mortality rate per 100,000 inhabitants, and deaths were standardized by age and gender and redistributed per to ill-defined causes, stratified by age group and ethnicity/skin color. We applied the Negative Binomial model, containing the interaction between ethnicity/skin color and the Brazilian Deprivation Index (IBP).

Purpose: After failing primary and secondary hormonal therapy, castration-resistant and neuroendocrine prostate cancer metastatic to the bone is invariably lethal, although treatment with docetaxel and carboplatin can modestly improve survival. Therefore, agents targeting biologically relevant pathways in PCa and potentially synergizing with docetaxel and carboplatin in inhibiting bone metastasis growth are urgently needed.
Experimental Design: Phosphorylated (activated) AXL expression in human prostate cancer bone metastases was assessed by immunohistochemical staining.

To undertake a mixed-methodology implementation study to improve the well-being of men with gastrointestinal late effects following radical radiotherapy for prostate cancer. All men completed a validated screening tool for late bowel effects (ALERT-B) and the Gastrointestinal Symptom Rating Score (GSRS); men with a positive score on ALERT-B were offered management following a peer reviewed algorithm for pelvic radiation disease (PRD). Health-related quality of life (HRQoL) at baseline, 6 and 12 months; and healthcare resource usage (HRU) and patient, support-giver, staff experience and acceptability of staff training (qualitative analysis) were assessed.
