How colon cancer spreads to the lining of the belly

Defining the role of seed and soil in peritoneal metastasis evolution

NIH-funded research Harvard Medical School · NIH-11322029

This project looks at the genetic patterns that explain how colorectal cancer cells reach and grow on the peritoneal (belly) lining in people whose cancer has spread there.

What this research studies

If your tissue is included, researchers will examine tumor samples from people whose colorectal cancer spread to the peritoneum and read DNA from several regions of each tumor. They will compare cases that spread at the same time as the original tumor (synchronous) with those that appeared later (metachronous) to see whether cancer cells take different routes to the belly lining. The team will use clinical records and genomic data from a large international group of about 103 patients to link genetic patterns to how the disease behaved. This work aims to point to markers of aggressive peritoneal spread and to suggest targets for future tests or treatments.

Who could benefit from this research

Good fit: Ideal candidates are people who had colorectal cancer that later involved the peritoneum and who have tumor tissue and clinical records available from surgery or biopsy.

Not a fit: People with early-stage colon cancer that never spread, those without available tumor tissue, or anyone seeking immediate therapeutic benefit are unlikely to receive direct benefit from this retrospective genomic research.

Why it matters

Potential benefit: Better understanding of how peritoneal metastases form could lead to earlier detection, improved prognostic tests, and new treatment targets for people with colorectal cancer that spreads to the belly lining.

How similar studies have performed: Genomic studies of other metastatic sites have revealed clinically useful patterns, but detailed genomic work focused on peritoneal metastases is relatively new and has only limited preliminary data so far.
