Sacrococcygeal teratoma: Long-term outcomes. A UK CCLG Surgeons Group Nationwide Study

Sacrococcygeal teratoma (SCT) is a rare paediatric germ cell tumour (1:40,000). Long-term data regarding urinary tract and bowel function after SCT resection is limited to few studies. A UK Children's Cancer and Leukaemia Group (CCLG) Surgeons multicentre study aimed to critically analyse long-term functional outcomes in patients following resection of SCT.Nationwide study of UK paediatric surgical oncology centres using a standardised data collection form. All index cases of newborn infants and children16 years with SCT diagnosis during 2005-2015 were included.165 SCT patients treated at 14 UK paediatric surgical oncology centres were included. Median age at presentation was 1 day [interquartile range, IQR: 0-25]; median age at surgery was 10 days [IQR: 4-150]. One hundred seventeen (70%) were female and 48 (30%) male. Antenatal diagnosis was made in 44% index cases. Total 59% of patients were Altman Stage I or II lesions. Follow-up data were available in 83% cases. Tumour recurrence occurred in 13 (7%) patients at median age 13 months [IQR: 8.75-30 months]. Fifty-nine (36%) of 165 patients had documented adverse bladder or bowel dysfunction. Twenty-two (37%) cases required urinary clean intermittent catheterisation (CIC) urology health care, with eight patients (14%) needing operative intervention to control management of bowel dysfunction.This UK CCLG study showed 36% of SCT patients develop bladder or bowel dysfunction after primary tumour resection. Functional assessment of bladder and bowel function is mandatory during after-care follow-up of all SCT patients. A multidisciplinary care pathway, with surgeon speciality groups including surgical oncology, paediatric urology and paediatric colorectal specialists, is strongly advised to facilitate 'best practice' monitoring of long-term health and improve patient quality of life (QoL) into adulthood.
