ABSTRACT
OBJECTIVES:
Pediatric sex cord stromal tumors (SCSTs) are extremely rare and there are no reported data from Africa. The authors evaluated the outcomes of children and adolescents with biopsy-proven SCSTs in preparation for the introduction of a national protocol. MATERIALS ANDMETHODS:
Retrospective data were collated from 9 South African pediatric oncology units from January 1990 to December 2015. Kaplan-Meier analysis was performed to estimate overall survival (OS) and event-free survival.RESULTS:
Twenty-three patients were diagnosed with SCSTs, 3 male and 20 female individuals, during the study period. Histologies included 1 thecoma, 9 Sertoli-Leydig cell tumors, and 13 juvenile granulosa cell tumors. Stage I tumors predominated (n=14; 60.9%), with 2 stage II (8.7%), 5 stage III (21.7%), and 2 stage IV tumors (8.7%). The upfront resection rate was 91.3% with no reported surgical morbidity or mortality and an OS of 82.1%. Chemotherapy approaches were not standardized. Most children (81.8%), except 2, had recognized platinum-based regimens. Chemotherapy-related toxicity was minimal and acceptable. Assessment of glomerular filtration rate and audiology assessments were infrequent and not standardized. Three patients were lost to follow-up.CONCLUSIONS:
Although the numbers in this cohort are small, this study represents the first national cohort in Africa. The 5-year OS of 82.1% was encouraging. Standardized management of rare tumors like SCSTs is critical to improve ensure OS and address potential long-term sequelae.
