[Clinical and pathological features of 23 patients with primary lymphoma of the testis].

Objective: To study the clinical and pathological features of primary lymphoma of the testis and try to find out the rational treatment modality.
Methods: Retrospective and follow-up analysis was conducted in 23 patients with primary lymphoma of the testis. Survival analysis was performed by Kaplan-Meier process.
Results: The primary clinical symptom was painless tumefaction. 78.3% lesions were Stage I(E) on diagnosis. Most of them were intermediate grade B cell lymphoma. All patients received orchiectomy followed by chemotherapy and some followed by radiotherapy. The median survival time was 42 months. The overall survival rates at 1, 3 and 5 years were 100.0%, 59.8% and 36.5%, respectively. The disease-free survival rates at 1, 3 and 5 years were 66.7%, 42.3% and 36.3%, respectively.
Conclusion: Primary lymphoma of the testis is preferably treated by multi-modality treatment. More than 6 cycles of chemotherapy is rational after orchiectomy. Regional radiotherapy tends to reduce the local relapse.
