Cytoreductive surgery and hyperthermic intra-peritoneal chemotherapy for highly mucinous transverse colon adenocarcinoma in a paediatric patient: a multidisciplinary approach

We report the first known case of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) performed in a 13-year-old paediatric patient for highly mucinous colorectal adenocarcinoma with peritoneal metastases. This complex procedure was made possible through close collaboration between two tertiary centres, overcoming significant logistical and clinical challenges. The case underscores the importance of flexible multidisciplinary planning in rare paediatric oncology scenarios and demonstrates CRS-HIPEC as a safe and viable treatment option in selected patient with peritoneal malignancies.
