Individual Response to Hyperthermic Intraperitoneal Chemotherapy (HIPEC) Treatment of Peritoneal Carcinomatosis From Peritoneal Mesothelioma or Atypical Mesothelial Proliferation or From Ovarian, Colorectal, or Appendiceal Histologies

Background: Cytoreductive surgery (CRS) removes tumors in the abdomen. HIPEC is hyperthermic (heated) chemotherapy that washes the inside of the abdomen. CRS with HIPEC may help people with peritoneal carcinomatosis. These are tumors that have spread to the lining of the abdomen from other cancers. Researchers think they can improve the results of CRS with HIPEC treatment on these tumors by choosing the chemotherapy drugs used in HIPEC. Objective: To see if HIPEC after CRS can be improved, using either a model called the SMART (Sustained Microenvironment for Analysis of Resected Tissue) System or using 3-D cell culture (organoid) models, in order to test different chemotherapy drugs on tumors that were surgically removed prior to HIPEC treatment (these models are not attached to the body) versus tumors that were treated with HIPEC while still inside the body before being immediately surgically removed. Eligibility: Adults ages 18 and older who have peritoneal carcinomatosis that cannot be fully removed safely with surgery. Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Electrocardiogram (EKG) Computed tomography (CT) scan Other imaging scans, as needed Tumor biopsy, if needed Laparoscopy (small cuts are made in the abdomen, and a tube with a light and a camera is used to see the organs in the abdomen), if needed Participants will enroll in NIH protocol #13C0176. This allows their tumor samples to be used in future research. Some screening tests may be repeated in the study. Participants will have CRS. As many of their visible tumors will be removed as possible during surgery except for a few specific tumors left to receive the HIPEC treatment. Then they will receive HIPEC and the remaining tumors will be immediately removed. Participants will be in the hospital for 7-21 days after this surgery (CRS with HIPEC). Participants will give tumor, fluid samples (from the abdomen during surgery), blood, saliva, cheek swab, and stool for research. They will complete surveys about their health and quality of life. Participants with peritoneal mesothelioma (mesothelioma primary only) will have genetic (DNA) testing to determine clinical (CLIA level) germline BAP1 status for research use. Participants will have follow-up visits for up to 5 years from CRS with HIPEC. If there is disease progression, participants may have CRS with HIPEC again. Participants will then have follow-up visits for up to 5 years from the date of last CRS with HIPEC. ...

JAB-21822 in Combination With Cetuximab in Patients With Advanced CRC and Other Solid Tumors With KRAS G12C Mutation

This study is to evaluate the safety, tolerability, pharmacokinetics and antitumor activity of JAB-21822 in combination with cetuximab in patients with advanced colorectal cancer，advanced small intestine cancer and advanced appendiceal cancer with KRAS p.G12C mutation.

A Feasibility Study of Mass-Based Response Drug Screening to Guide Personalized Hyperthermic Intraperitoneal Chemotherapy for High-Grade Appendiceal and Colorectal Adenocarcinoma With Peritoneal Metastasis

This study will evaluate the role of mass-based response testing (MRT) to select and deliver personalized hyperthermic intraperitoneal chemotherapy (HIPEC) regimens to patients with peritoneal metastasis (PM) from high-grade appendiceal adenocarcinomas (HGAA) and colorectal cancer (CRC).

Intraoperative Imaging of Gastrointestinal Malignancies Using Pafolacianine (CYTALUX™)

This is an open-label study in adults to determine feasibility of using CYTALUX™ (pafolacianine) injection with near-infrared (NIR) fluorescent imaging for detecting any type adenocarcinoma (gastric, esophageal and appendiceal).

Genetics of Appendix Cancer Study

The GAP Study is a prospective cohort study designed to comprehensively investigate genetic variations that may contribute to cancer development among individuals diagnosed with appendix/appendiceal cancer who are ages 18+ years.

Study of Intravenous and Intraperitoneal Paclitaxel and Oral Nilotinib for Peritoneal Carcinomatosis From Colorectal, Appendiceal, Small Bowel, Gastric, Cholangiocarcinoma, Breast, Ovarian, or Other Gynecologic Primary Cancer

Background: Tumors that have spread to the lining of the abdomen from other cancers, such as cancer of the appendix, colon, or ovary, are called peritoneal carcinomatosis. In most cases, outcomes are poor. Researchers want to test a new treatment. Objective: To learn if the combination of oral nilotinib plus paclitaxel given by IV and directly into the abdomen can reduce tumors enough for people to have surgery. Eligibility: Adults aged 18 and older with peritoneal carcinomatosis that is too widespread for surgery. Design: Participants will be screened with: Physical exam Medical history Blood and urine tests Electrocardiogram Laparoscopy. They will get general anesthesia. Small cuts will be made in their abdomen. Tissue and fluid samples will be taken. Surveys about their health CT scans of their torso Participants will have up to 4 more laparoscopies. During the first procedure, a port will be placed under the skin of their abdomen (an IP port). It will be attached to a catheter that is placed in their abdomen. Participants will get treatment in 3-week cycles, for 3 or 6 cycles. They will take nilotinib by mouth twice daily. They will get paclitaxel by IP port (once per cycle) and by IV (twice per cycle). After cycles 3 and 6, they will have a laparoscopy and CT scans. Then they may take nilotinib and get IV paclitaxel for up to 1 year. At study visits, participants will repeat some screening tests. About 6 weeks after treatment ends and then every 3 months for 3 years, participants will have follow-up visits at NIH or with their local doctor.

Locally ablatIVe thErapy for oLigo-progressive gastrOintestiNal maliGnancies (LIVELONG)

This is a phase 2 pragmatic study that evaluates the clinical benefit of continuing systemic therapy with the addition of locally ablative therapies for oligo-progressive solid tumors as the primary objective. The primary outcome measure is the time to treatment failure (defined as time to change in systemic failure or permanent discontinuation of therapy) following locally ablative therapy.

Molecular Characterisation of Appendiceal Cancer

Patients ≥ 18 years old who have been diagnosed with appendiceal cancer with peritoneal metastases, have had cytoreductive surgery, have availability of archival tumour tissue and have consented to our institutional biobank program or have a waiver of consent for deceased patients who have not had the opportunity to provide biobank consent (requested at the time of ethics review). Descriptive analysis of the proportion of genetic mutations identified in appendiceal cancers. This is given by the percentage of pathogenic mutations in the peritoneal metastasis compared to the primary tumour.
