Nowadays, polyp malignancy transformation is relatively rare. If malignancy transformation is confirmed, timely follow-up treatment is required. The most commonly used treatment method currently is surgical treatment. Some patients can opt for radiation therapy, and if the condition is more severe, a comprehensive treatment plan that combines surgery, radiation therapy, and chemotherapy may be needed. After the treatment is finished, long-term regular check-ups are necessary, generally recommending a check-up every three months to monitor for any local recurrence or distant metastasis. Overall, the earlier the disease is treated, the better the treatment outcome. However, if the onset of the disease is later and the condition is more severe, the treatment outcome is relatively poorer.
