Leydig-cell tumour of the testis: retrospective analysis of clinical and therapeutic features in 204 cases
2020
Overview
PurposeLeydig-cell tumours (LCT) of the testis are poorly understood clinically. The aim of this report is to analyse the clinical characteristics of LCT in a large patient sample and to compare these findings with corresponding data of germ-cell tumours (GCT).MethodsIn a sample of 208 patients treated during 1995–2017 in 33 institutions, the following characteristics were registered: age, presenting symptoms, primary tumour size, testis-sparing surgery (TSS) or orchiectomy, malignancy, laterality, medical history, and outcome. Data analysis included descriptive statistical methods and logistic regression analysis.ResultsThe ratio LCT:GCT is 1:23 (4.4%). The findings are as follows: median age 41 years, undescended testis 8%, bilateral LCTs 3%, malignant LCT 2.5%, contralateral GCT 2.5%, incidental detection 28%, scrotal symptoms 43%, infertility 18%, elevated estradiol levels 29%. TSS was performed in 56% with no local relapse. Of the patients with malignant LCT, one was cured through surgery.ConclusionLCT is rare, with a relative frequency (relative to GCT) of 1:23. Malignancy is found in 2.5%. LCT and GCT share a number of clinical features, e.g. bilaterality, history of undescended testis, and presenting age. TSS is safe in benign LCT. Surgery is the treatment of choice in malignant LCT.
