Brief summary

This is a pilot study gathering and using samples and data from patients with gastrointestinal peritoneal carcinomatosis. Participants will be asked for permission to provide blood and ascites/peritoneal wash fluid, tumor samples during their planned surgical procedure.

Interventions

OTHERBiospecimen Collection (Blood, Ascites/Peritoneal Wash Fluid and/or Tumor Samples)

Subjects with a known diagnosis of GI primary tumor with or without PC, with a planned standard of care surgery.

Design outcomes

Primary

MeasureTime frameDescription
Establishment of angioarchitechture of peritoneal lesions through Optical Coherence Tomography Angiography (OCTA)Up to 4 yearsEstablishment and evaluation of angioarchitecture of peritoneal lesions through OCTA imaging obtained during surgery.
Development of individual patient-derived peritoneal carcinomatosis (pdPC) vascularized micro-tumor (VMT)Up to 4 yearsSuccessful establishment of multicellular pdPC VMT models from metastatic and/or primary tumor tissue with increasing tumor volume over a 14 day period.

Secondary

MeasureTime frameDescription
Overall Survival (OS)Up to 4 yearsSurvival analysis will utilized to study association between in vitro model and patient clinical response. The duration of time from start of treatment to time of progression or death, whichever occurs first.
Compare response of therapeutic regimens in a pdPC VMT to the observed clinical response (by RECIST criteria or diagnostic laparoscopy)Up to 4 yearsResponse to therapy in a pdPC VMT will be correlated with the clinical response observed in patients treated with similar regimens using either RECIST criteria if measurable disease is available or by diagnostic laparoscopy performed as part of standard of care to assess treatment response
Progression-Free Survival (PFS) at 6 months6 monthsSurvival analysis will utilized to study association between in vitro model and patient clinical response. Progression-free survival (PFS) is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first. Estimates at 6 months will be made.
