Background: Peritoneal carcinomatosis from abdominal tumors is an uncommon condition in children usually associated with dismal prognosis. Hyperthermic intraperitoneal chemotherapy (HIPEC) following complete macroscopic surgery has been demonstrated to be safe and of benefit in selected cases. Experience in pediatrics is scarce.
Methods: We retrospectively reviewed the medical files of patients under the age of 18years with an abdominal malignancy and peritoneal carcinomatosis who had been treated with HIPEC in our institution between March 2001 and April 2012. HIPEC had been administered using the open technique with oxaliplatin (300mg/m(2)) and irinotecan (200mg/m(2)) or oxaliplatin alone (460mg/m(2)) in the peritoneal cavity for 30minutes at 43°C and an intravenous perfusion of leucovorin (20mg/m(2)) and 5-fluorouracil (400mg/m(2)).
Results: Nine patients had undergone HIPEC. Grade 3-4 complications had occurred in seven patients and were intraabdominal (n=3) or extraabdominal (n=8). No procedure-related deaths had occurred. Four patients are alive and in complete remission after a median follow-up of 4.9years (1.7-9.6). However one relapsed after HIPEC and required additional salvage therapy.
Conclusions: HIPEC could be considered in patients with peritoneal carcinomatosis from primary abdominal tumors. Its complications are manageable by an experienced multidisciplinary team. There are four long-term survivors, one after a relapse.
