Management and outcome of paediatric testicular tumours – A 20 year experience
Journal of Pediatric Surgery(2021)
Abstract
Objective
: To report a 20-year experience highlighting management and outcome(s) of paediatric testicular tumours.
Patients and Methods
: All males (< 19 years) with an index diagnosis of testicular tumours during the era(s) 1998–2018 in North West England were identified. Data were collected regarding age at diagnosis, disease stage, surgical operations, tumour biology and outcome(s).
Results
: A total of 34 male patients were identified. Median age at primary diagnosis was 94 months (range: 0–229 months). Eighteen tumours were benign and 16 malignant. Twenty cases (59%) were recorded in pre pubertal children and 14 (41%) in post pubertal males . In the pre pubertal group (0–11 years) - 15 cases of germ cell tumours (unrelated to germ cell neoplasia in situ – non-GCNIS derived) were recorded, including six yolk sac lesions, eight teratomas and one mixed teratoma/yolk sac tumour (pre-pubertal type). Four males with sex cord-stromal tumours included one juvenile granulosa cell tumour, two Sertoli cell tumours and one Leydig cell tumour. One miscellaneous type tumour notably a papillary cyst adenoma was also identified. In the post pubertal male cohort (>12 years) (n = 14) – four non-GCNIS derived tumours were identified (3 epidermoid cysts and one teratoma), eight cases of germ cell tumour derived from germ cell neoplasia in situ (GCNIS derived) included one teratoma, six with mixed germ cell tumours and one embryonal carcinoma. Two males had sex cord stromal tumours: (Leydig cell and granulosa cell biology). Twenty-eight patients underwent high radical inguinal orchidectomy(s) with one male also requiring retroperitoneal surgery to clear distant locoregional disease and a further single case thoracotomy and metastasectomy. Six patients had lesions suitable for ‘testicular sparing’ surgery. Six patients had metastatic disease at presentation (18%). Overall study survival was 97%. A single fatality occurred in an adolescent male with a mixed GCT harbouring liver, lung and para-aortic disease who died 48 months after initiating treatment.
Conclusion
: We highlight one of the largest study series of paediatric testicular tumours in the UK and Europe. Non-GCNIS derived tumours accounted for the most common tumour biology (56%). Survival for paediatric testicular tumours is reassuringly generally excellent. Delayed presentation however with a malignant testicular tumour may be associated with poor outcome(s).
