At the Peritoneal Surface Oncology Group International (PSOGI) meeting in Barcelona this October, Alliance Board Member Dr. Vadim Gushchin presented a new perspective on how surgeons should be trained to care for patients with peritoneal surface malignancies (PSM)—a group of rare cancers that spread inside the abdominal cavity, titled " What is special about teaching and learning PSM surgery? ". PSMs are cancers that spread inside the abdominal cavity , forming many small or

A recent study by Mercy Medical Center reveals that despite longer delays to treatment and more advanced disease at presentation, out-of-state patients with rare appendix cancers achieve comparable long-term outcomes to local patients when treated at a high-volume specialized center. Key findings from the research, published July 2025 in The American Surgeon, include: Patients traveling from out of state waited an average of 4.6 months from diagnosis to surgery, compared to 2

This study focused on a key challenge: in many bowel cancers, especially stromal-rich types (those with lots of supporting tissue, or stromal cells, around the tumor), immune therapies aren’t working as well as hoped. Researchers investigated how certain “support” cells within the tumor (called stromal cells) may be actively helping the cancer by suppressing the body’s immune system. Then they investigated how to turn the immune system back on again in these hard-to-treat can

When you hear “clinical trials,” you might think of the drug companies doing studies of new medicines. But did you know that federally funded trials—backed by government agencies—play a unique and absolutely critical role in cancer research? A recent study shows just how important they are for rare cancers, children, and complex treatment strategies.
