[The efficacy of the surgical treatment of colorectal cancer with metastasis into the perienteric fatty tissue].
Metastasizing to the surrounding fatty tissue is a rarely encountered feature of colorectal carcinoma. Metastases were identified in 34 of those patients (n = 755) having been operated on (4.5% observations). The above metastases were found to range from 3 to 7 mm, having no associative ties either with the primary tumor or the regional lymphatic nodes along the colonic and rectal arterial vessels. The presence of the colorectal carcinoma metastases to the surrounding fatty tissue tends to strikingly worsen the prognosis as to long-term survival of patients after surgical treatment. A 10-year survival of patients presenting with colorectal carcinoma metastases to the surrounding fatty tissue was estimated to be 15 to 17% which is more than 3 times inferior to the effectiveness of radical operations in patients presenting with the third stage of the process but free from such metastases. The secured data attest to the need for reconsideration of the colorectal carcinoma staging classification that is in force in our country and for bringing it to conformity with international standards.
