What is Signet Ring Cell Cancer?

Signet ring cell cancer gets its name from the resemblance of the cancer cells to signet rings when viewed under a microscope. This cancer most often develops in the abdominal cavity (the peritoneum), typically in the stomach, although it can start in the colon, rectum, appendix and other organs. When it first appears in the colon, for example, signet ring cell cancer frequently moves through the colonic wall to spread to the peritoneum.

At University Hospitals Seidman Cancer Center, we can diagnose and treat signet ring cell carcinomas in any part of the body. However, the focus of our current research efforts is signet ring cell cancer of the colon, rectum and appendix. About one to two percent of colorectal cancers diagnosed in the U.S. every year are of the signet ring cell variety. Of the approximately 150,000 cases of colorectal cancer diagnosed in the U.S. annually, signet ring cell cancer accounts for about 1,500 to 3,000 cases.

Symptoms of Signet Ring Cell Cancer

Symptoms of signet ring cell cancer often mimic the symptoms of inflammatory bowel disease. Specific symptoms include:

  • Abdominal pain
  • Changes in bowel habits
  • Diarrhea
  • Constipation
  • Rectal bleeding
  • Weight loss

How to Schedule an Appointment

Patients can call our cancer information service line at 216-844-5432 (800-641-2422) to discuss appointment options. New patients will typically meet with the medical oncologist first. Our nurse navigator can work with you to obtain the medical records needed for your visit. The records we ask for include:

  • Note from the medical oncologist (or other cancer doctor) if you have already seen one
  • Biopsy report
  • Imaging results (CT Scans or MRI Scan)
  • Most recent blood work: Comprehensive Metabolic Panel, Complete Blood Count (CBC) and Carcinoembryonic Antigen (CEA) test

International patients should contact the Center for International Relations at 216-844-5657 or .
