Overall clinical and trichoscopic analysis performed in patients who underwent pressurized intraperitoneal aerosol chemotherapy (PIPAC) treatment for peritoneal carcinomatosis – initial trial preliminary report

Introduction
Cutaneous adverse events are among the remaining problematic issues of current oncology. The term peritoneal carcinomatosis (PC) refers to the advanced cancer stage. The innovative treatment of PC includes the use of pressurized intraperitoneal aerosol chemotherapy (PIPAC).

Aim
To present a preliminary report from an initial trial aimed at an overall clinical and trichoscopic analysis performed in patients who underwent PIPAC treatment due to PC.

Material and methods
For all steps of this study we obtained the consent of the local bioethics commission #KB 196/2018. Three different hair assessment methods were used in our study: 1) general clinical and patient self-feeling assessment; 2) hair pull test; 3) and trichoscopic analysis.

Results
No hair or scalp disorders were noted in the observation period. In the self-feeling test assessment the vast majority recognized their hair as being of comparable quality or even better in quality compared to previous forms of chemotherapy they had undergone. In all patients we observed a reduction of hair loss in the pull test in the hospitalization period. In trichoscopic analysis we found all determinants and signs of hair disorders in the assessed group.

Conclusions
The PIPAC is safe and is not a burdensome or aggressive form of therapy, especially according to the very important factors influencing the potential quality of hair and hair loss. The authors, however, realize that to obtain comprehensive results and evaluate this novel and promising method we need to perform more research without any limitations like those in our study.
