OBJECTIVE: To describe clinical management and outcomes of a cohort of patients with malignant mesothelioma of the tunica vaginalis testis (MMTVT) who received treatments beyond radical orchiectomy.
METHODS: Patients with confirmed MMTVT at a single tertiary care institution were identified. Treatments, pathologic outcomes, and survival were recorded. Prognostic variables associated with survival were analyzed with a Cox proportional hazards model and Kaplan-Meier curves.
RESULTS: Overall, 15 patients were included. Initial presentation was a scrotal mass in 7 of 15 (47%) and hydrocele in 5 of 15 (33%) patients. Clinical staging revealed enlarged nodes in 5 of 15 (33%) patients. Radical orchiectomy was the initial treatment in 5 of 15 (33%) patients. Positive surgical margins were found in 6 of 14 (43%) radical orchiectomies and were associated with worse survival (P = .007). The most frequent histologic subtype was epithelioid, associated with better survival (P = .048). Additional surgeries were performed on 12 of 15 (80%) patients. Pathologic examination revealed MMTVT in 6 of 12 (50%) hemiscrotectomies, 7 of 8 (88%) retroperitoneal lymph node dissections, 1 of 7 (14%) pelvic lymph node dissections, and 10 of 10 (100%) groin dissections. Five patients received adjuvant chemotherapy. Two also received adjuvant radiation therapy. Three patients with lymph node involvement remain no evidence of disease over 6 years after diagnosis. After a median follow-up of 3.5 years (interquartile range: 1.2-7.2), 5 patients have died, all of MMTVT; the median overall survival has not been reached. Common sites of relapse were lungs (5 of 7) and groin (3 of 7).
CONCLUSION: The pattern of metastatic spread of MMTVT is predominantly lymphatic. Nodes in the retroperitoneum and the groin are commonly involved. Prognosis is poor, but there may be a role for aggressive surgical resection including hemiscrotectomy, and inguinal and retroperitoneal lymph nodes.
