Abstract
Purpose: Mesothelioma of the tunica vaginalis testis (MTVT) is a rare tumor, and currently, there are no published treatment recommendations.
Methods: We performed a systematic literature review and synthesized clinical presentation, clinicopathological factors associated with metastatic disease, treatment options, and outcomes in men with MTVT.
Results: We included 170 publications providing data on 275 patients. Metastatic disease occurred in 84/275 (31%) men with malignant MTVT: Most common sites included retroperitoneal lymph nodes (LNs) (40/84, 48%), lungs (30/84, 36%), and inguinal LNs (23/84, 27%). Invasion of the spermatic cord or scrotum was the only risk factor for local recurrence [odds ratio (OR) 3.21, 95% confidence interval (CI) 1.36-7.57]. Metastatic disease was associated with age ≥ 42 years (OR 3.02, 95% CI 1.33-6.86), tumor size ≥ 49 mm (OR 6.17, 95% CI 1.84-20.74), presence of necrosis (OR 8.31, 95% CI 1.58-43.62), high mitotic index (OR 13.36, 95% CI 1.53-116.51) or angiolymphatic invasion (OR 3.75, 95% CI 1.02-13.80), and local recurrence (OR 4.35, 95% CI 2.00-9.44). Complete remission in the metastatic setting was observed in five patients, most of whom were treated with multimodal therapy. Median survival in patients with metastatic disease was 18 months (IQR 7-43).
Conclusion: Malignant MTVT is a rare but aggressive disease. Since local recurrence is a risk factor for metastatic progression, we recommend aggressive local treatment. Survival and response to any treatment in the metastatic setting are limited.
