Abstract：
Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a promising technic for unresectable peritoneal metastasis (PM). Targeted therapies such as bevacizumab have demonstrated their efficacy in advanced colorectal and ovarian cancer. We aimed to evaluate the feasibility and safety of this bidimensional therapeutic association.
A prospectively maintained PIPAC database was retrospectively analyzed from December 2015 to March 2018. All patients who underwent PIPAC for unresectable PM were selected. Patients with systemic chemotherapy including bevacizumab (BEVA group) were compared with patients with systemic chemotherapy without bevacizumab (NON-BEVA group). Major morbidity and mortality were analyzed.
134 patients underwent 397 PIPAC in Lyon Sud University Hospital. 26 Patients had 88 PIPAC in the BEVA group were compared to 108 patients who had 309 PIPAC in the NON-BEVA group. Patients in the BEVA group demonstrated a higher Peritoneal Cancer Index (PCI 20 vs. 16, p < 0.001). There was no statistical difference in overall 30-day morbidity (BEVA: 13 (14.8%) vs NON-BEVA: 29 (9.4%); p = 0.147). There was no statistical difference for grade III-IV complications (BEVA: 4 (4.5%) vs NON-BEVA 10 (3.2%); P = 0.521). Major complications from BEVA group were as follow, 2 bowel obstructions, one hematoma and one severe hypersensitivity reaction to platinum compound. There was no 30-day mortality in the BEVA group compared to 6 (5.5%) mortality in the NON-BEVA group.
PIPAC associated with bevacizumab is feasible, safe and well tolerated. The potential oncologic benefit of the concomitant use of bevacizumab and PIPAC remains to be evaluated.
