This study comprehensively analyzed 37 studies involving 1116 patients and found that Sacrococcygeal teratoma (SCT) has long-term effects on bladder/bowel function, especially in malignant tumors and patients requiring reoperation(s).
Sacrococcygeal teratoma (SCT) is a rare neoplasm affecting 1:35,000 newborns. Long-term follow-up from small observational studies report impaired bladder/bowel function. This current study compre-hensively analyses all published studies to better define true long-term functional sequelae. Medline/ Embase databases were searched with PRISMA guidelines. Final analysis yielded 37 studies involving 1116 patients (854 female; 77%). Individual datasets were available in 14 studies (222 patients). Ac-cording to Altman classification -298/845 (35%) were Type I, 252/845 (30%) Type II, 133/845 (16%) Type III, and 128/845 (15%) Type IV tumours. Most neoplasms were benign (640/858; 75%), 77/858 (9%) immature and 141/858 (16%) malignant. Abnormal bladder function was reported in 7/39 (18%) Altman Type I, 23/61 (37.7%) Type II, 11/34 (32.4%) Type III, and 15/25 (60%) Type IV cases (p = 0.007). Adverse urological outcomes were notably common in immature/malignant neoplasms vs benign tumours and in patients requiring reoperation(s); p = 0.002 and p = 0.01. Bowel dysfunction was evident in 19% index cases and constipation in 26% with no significant association(s) with tumour characteristics. Higher Altman stage, unfavourable tumour biology and reoperation are associated with poor functional out-come(s). Multidisciplinary management from primary diagnosis of SCT is crucially important for all patients to best optimise functional outcomes across surgical specialities.(c) 2022 Elsevier Ltd, BASO -The Association for Cancer Surgery, and the European Society of Surgical Oncology.
