Severe hypersensitivity reactions to platinum compounds post-pressurized intraperitoneal aerosol chemotherapy (PIPAC): first literature report

Abstract

Background

Pressurized intraperitoneal aerosol chemotherapy (PIPAC) shows encouraging results for patients with unresectable peritoneal metastasis. Several reports demonstrated the safety of the procedure combined with systemic chemotherapy, with a low rate of complication. The aim of this study is to report severe hypersensitivity reactions to platinum compounds (SHRPC) during PIPAC procedures.

Methods

All patients who underwent PIPAC for non-resectable PC in Lyon Sud University hospital were included in a prospective institutional database. All patients who presented a SHRPC after PIPAC were included in our analysis.

Results

One hundred and thirty-two patients underwent 383 PIPAC procedures between December 2015 and December 2017. oxaliplatin's and cisplatin–doxorubicin's protocols were used in 71 and 312 PIPAC, respectively. Four patients (3%) developed SHRPC; two patients (2.8%) after oxaliplatin and two patients (0.6%) after cisplatin–doxorubicin protocols. SHRPC occurred during the 6th PIPAC with cisplatin–doxorubicin protocol and during 2nd and 3rd PIPAC of the oxaliplatin protocol. Three events appeared within 15 min and one event occurred 50 min following nebulization. All the SHRPC have been managed successfully without any complication.

Conclusions

This is the first report of SHRPC after PIPAC. The physician must constantly keep this rare but life-threatening complication in mind, especially after repeated PIPAC administration or previous platinum-based systemic chemotherapy.
