What Are Some Recommended Treatments for Tubulovillous Adenoma?
Recommended treatments for tubulovillous adenoma typically include removing the entire polyp and checking it for cancer, according to the American Cancer Society. Physicians often remove tubulovillous adenomas when they observe them during colonoscopies, but large adenomas may require surgery for removal. Patients should discuss treatment options with their physicians if the physicians biopsy the polyps during colonoscopies but do not remove them completely. Physicians use repeat colonoscopies to look for new growths and signs of cancer.
Tubulovillous adenomas are polyps that are display a combination of both tubular and villous growth patterns, as the American Cancer Society explains. Generally, adenomas that are smaller than 1/2 inch have a tubular growth pattern. Larger adenomas typically have a villous growth pattern, and they are more likely to become cancerous. Doctors use growth patterns to establish when patients should return for colonoscopies to check for possible colon cancer development. Other factors that affect the scheduling of repeat colonoscopies include the number of adenomas present, whether they are villous, have dysplasia or appear cancerous.
When doctors examine polyps under a microscope and observe that they do not resemble cancer, they consider the polyps to have low-grade dysplasia, as the American Cancer Society details. Polyps with high-grade dysplasia are growths that more closely resemble cancer.
