A prospective, randomized study analyzing sartorius transposition following inguinal-femoral lymphadenectomy.

Objectives: Based on the reduced morbidity seen in our retrospective study, we undertook a prospective, randomized trial to determine whether transposition of the sartorius muscle improves post-operative morbidity in women with squamous cell carcinoma of the vulva undergoing inguinal-femoral lymphadenectomy.

Methods: Patients with squamous carcinoma of the vulva requiring inguinal-femoral lymphadenectomy were randomized to undergo sartorius transposition or not. All patients received perioperative antibiotics, DVT prophylaxis, and closed suction surgical site drainage.

Invasion of interstitial matrix by a novel cell line from primary peritoneal carcinosarcoma, and by established ovarian carcinoma cell lines: role of cell-matrix adhesion molecules, proteinases, and E-cadherin expression.

Objective: Primary peritoneal carcinosarcomas are similar to ovarian carcinomas in that they can metastasize by intraperitoneal dissemination; therefore, invasion of the submesothelial interstitial (stromal) matrix is an integral part of the pathology. Our objective was to study cell-matrix interactions that may influence invasive behavior of a novel, primary peritoneal carcinosarcoma cell line (PC880), and to assess how these cell-matrix interactions are different from frequently studied cultured ovarian carcinoma cells NIH:OVCAR-3, SKOV-3, and ES-2. We also wanted to determine how the expression of the cell-cell adhesion molecule E-cadherin is related to invasive behavior.
