Feasibility of Single Tumorspot Treatment in Peritoneal Carcinomatosis via Close Range Doxorubicin Impaction in Pressurized Intra-Peritoneal Aerosol Chemotherapy (PIPAC)

Posted on

Pressurized Intraperitoneal Aerosol Chemotherapy (PIPAC) is a well-established, yet not fully evaluated new treatment approach for peritoneal carcinomatosis with the aim at enabling localized application of chemo aerosol within the abdominal cavity. Distribution inhomogeneity in PIPAC has been previously indicated in prior experiments. This study was conducted to investigate whether this finding can be used to achieve localized high drug concentrations into micro metastasis. PIPAC construct was built using a hermetic container system which mimics the abdominal cavity. Fresh parietal peritoneum portions from post-mortem swine were cut into samples and placed vertically in the center of a box. The Micropump© (MIP) was introduced via trocar at the side of the box and located at 1cm from the samples to enable close range impaction of the aerosolized doxorubicin with the samples. Doxorubicin penetration depth was radially measured by fluorescence microscopy from the center of targets to the outer rim. Tissue doxorubicin penetration in the tissue was lower towards the outer rim and further away from the center of the sprayjet. Maximal penetration of drug was achieved in the midpoint of the sprayjet with 417± 87(SD) µm and a minimal penetration was reached at 3 cm from center with 45 ± 20 (SD) µm….to read more: https://www.scitechnol.com/peer-review/feasibility-of-single-tumorspot-treatment-in-peritoneal-carcinomatosis-via-close-range-doxorubicin-impaction-in-pressurized-intrap-sG1B.php?article_id=6082
