ASSESSMENT OF INCIDENCE OF METACHRONOUS NEOPLASMS AFTER SURGICAL RESECTION OF COLORECTAL CANCER

Abstract

ancer colon is the second most common cause of cancer in women and the third most common in men. Globally incidences vary 10-fold with highest rates in Australia, New Zealand, Europe and the US and lowest rates in Africa and South-Central Asia. However, in Egypt, CRC represent 4.2% of all cancers in male and 3.8% in females. In non-metastatic colon cancer, curative surgical resection is the principle of treatment. Patients diagnosed with colon cancer have an increased risk of metachronous colorectal cancer in the remaining part of the colon. So it's very important to keep the remaining part of colon from any developing tumors and try to discover it as early as possible and choose the most effective treatment. Metachronous colorectal cancer was defined as the second primary tumors that occurred more than 6 months after curative surgical resection without confirmation of local recurrence or primary tumor metastases. The aim of our study was to assess the incidence of Metachronous neoplasms after curative surgical resection of colorectal cancer and assess different risk factors for metachronous Cancer colon occurrence.
