Spots Global Cancer Trial Database for Study of Plasma Tumor-promoting Factors and Immune Function After Laparotomy, Cytoreductive Surgery and HIPEC vs. PIPAC in Patients With Peritoneal Metastasis

Study Description

Brief Summary: The general goal of this study is to investigate the effect of treatment on serum concentrations of proteins known to impact angiogenesis or tumor growth and establishment in patients with peritoneal metastasis of various origin. Since the immune system is thought, by many, to have an impact on tumor growth and development, this study also seeks to determine the impact of abdominal surgery on postoperative immune function in PM patients, as judged by proteins known to influence immune function. This study will not only characterize the postoperative plasma but also to determine if the magnitude of any of the changes noted is associated with a worse or improved oncologic outcome. The principle purpose of this study is to gather perioperative serum/plasma samples from patients with PM from a variety of different primary tumors (ovarian, gastric, and colorectal) undergoing either CRS and HIPEC versus PIPAC.

Detailed Description: The plasma samples obtained in this protocol will also be used to study the various plasma proteins that influence immune function as well as those that influence angiogenesis. In addition to the proteins mentioned above, there are also a large number of other proteins that have not been investigated thus far in the perioperative window; these proteins also merit assessment. The plasma obtained via this study and protocol will also be used to search for other tumor growth factors influenced by surgery or to investigate the impact of surgery on immune function. Aim 1: To determine perioperative serum levels, over time, of a variety of serum proteins including but not limited to IGFBP-3, VEGF, Ang 2, PlGF, sVCAM, CHI3L1, MMP-2, MMP-3, MCP-1 and proteins that influence immune function as well as other proteins in the following 2 groups of patients: 1. PM patients treated with CRS and HIPEC 2. PM patients treated with PIPAC. Aim 2: To compare the perioperative blood protein results between the 2 different groups of patients. Aim 3: To determine, within each group, a possible correlation between the magnitude of these effects on oncological outcome (patient overall survival). Aim 4: To search for other surgery-influenced plasma or cellular factors that may influence early postoperative tumor growth or that hold promise as tumor or prognostic markers.
