Prognostic value of baseline and serial carcinoembryonic antigen and carbohydrate antigen 19.9 measurements in patients with pseudomyxoma peritonei treated with cytoreduction and hyperthermic intraperitoneal chemotherapy.

BACKGROUND: Tumor markers are useful for diagnosis and follow-up. We studied the prognostic value of baseline and serial carcinoembryonic antigen ( CEA) and carbohydrate antigen 19.9 (CA19.9) measurements in patients with pseudomyxoma peritonei treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: Sixty-three patients with pseudomyxoma peritonei were treated with cytoreductive surgery and HIPEC. The tumor markers CEA and CA19.9 were collected before therapy and at 3-month intervals during follow-up. RESULTS: Preoperative CEA and CA19.9 levels were increased in, respectively, 75% and 58% of the patients. Baseline tumor marker values were related to the extent of tumor. Immediately after HIPEC, both tumor markers decreased markedly (P <.0001). CA19.9 was shown to be a more useful tumor marker than CEA for follow-up. During follow-up, a high absolute CA19.9 level (P =.0005) was predictive for imminent recurrence. Patients who never attained a normal CA19.9 level showed a higher recurrence rate at 1 year (53%; SE, 15%), in comparison to patients who did so (6%; SE 4%). The median lead time of increased CA19.9 to recurrence was 9 months. CONCLUSIONS: The measurement of the tumor marker CA19.9 is useful in evaluating therapy in patients with pseudomyxoma peritonei treated with cytoreductive surgery and HIPEC. CA19.9 is a prognostic factor for predicting recurrent disease.[1]
