Purpose:
To identify the role of systemic chemotherapy in the management of appendiceal malignancies.
Methods:
Over a 10-year period (2005 -2014), 52 patients with appendiceal neoplasms were treated at our Peritoneal Surface Malignancy Unit [14 (26.9%) disseminated peritoneal adenomucinosis (DPAM), 30 (57.7%) peritoneal mucinous carcinomatosis of appendiceal origin (PMCA) and 8 (15.4%) PMCA-I]. All patients (100%) underwent cytoreductive surgery (CRS) & hyperthermic intraperitoneal chemotherapy (HIPEC), while 20 (38.5%) of them also received perioperative systemic chemotherapy.
Results:
Mean peritoneal cancer index (PCI) was 23.6. Completeness of cytoreduction score (CC-S) was: CC-0 in 26 patients (50%), CC-1 in 20 patients (38.5%) and CC-2 in 6 patients (11.5%). High grade malignancy was reported in 27 patients (51.9%) and low grade malignancy in 25 patients (48.1%). More than half of the patients developed recurrence (n=36, 69.2%), while death was reported in 40.4% (n=21). Median overall survival (OS) in all histologic groups was 24 months for patients who received perioperative systemic chemotherapy and 14 months for patients who did not (p=0.048). Median disease free survival (DFS) in all histologic groups was 19 months for patients who received perioperative systemic chemotherapy and 10 months for patients who did not (p=0.034).
Conclusion:
We suggest that perioperative systemic chemotherapy serves as a helpful therapeutic tool in the management of peritoneal mucinous appendiceal carcinomas treated with cytoreductive surgery & HIPEC.
