ABSTRACT

<p><b>OBJECTIVE</b>To investigate the prognostic factors of colorectal cancer patients with liver metastasis in order to provide reference for clinical practice.</p><p><b>METHODS</b>Clinicopathological and follow-up data of 264 cases of colorectal liver metastasis in our department from January 1997 to January 2012 were analyzed retrospectively. Among these 264 patients, 217 underwent primary colorectal cancer resection, 33 underwent combined resection of primary colorectal lesion plus liver metastasis, and 14 received stoma creation alone. Besides, 197 patients received adjuvant chemotherapy, 14 received adjuvant radiotherapy, and 42 underwent interventional treatment. Clinicopathological features and treatment scheme affecting prognosis were analyzed and prognostic stratification analysis was performed according to emergence time of liver metastasis (synchronous or metachronous).</p><p><b>RESULTS</b>Of 264 patients, 1-, 3-, and 5-year overall survival rates were 77.0%, 31.7%, and 14.0%; median survival time was 25 months; 1-, 3-, and 5-year survival rates of synchronous colorectal liver metastasis were 68.8%, 22.3%, and 7.7%; 1-, 3-, and 5-year survival rates of metochronous colorectal liver metastasis were 95.8%, 49.0%, and 21.3%, whose difference was statistically significant (P<0.05). Multivariate analysis showed that primary tumor differentiation, CEA level, adjuvant chemotherapy, and radical resection were independent prognostic factors of colorectal cancer patients with liver metastasis (all P<0.05), while primary tumor differentiation, CEA level, and radical resection were independent prognostic factors of synchronous liver metastasis (all P<0.05), and primary tumor location and CEA level were independent prognostic factors of metachronous liver metastasis (all P<0.05).</p><p><b>CONCLUSIONS</b>Radical operation and adjuvant chemotherapy should be emphasized for colorectal liver metastasis, especially for synchronous colorectal liver metastasis. Simple resection of primary tumor can not improve the overall survival of patients with colorectal liver metastasis.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To recognize the characteristics of desmoplastic small round cell tumor (DSRCT) and improve the standard of diagnosis.</p><p><b>METHODS</b>We retrospectively reviewed the clinical data on the treatment of 2 patients with DSRCT in terms of their conditions, tissue sources, pathologic characteristics, immunohistochemical methods, clinical manifestation, diagnosis, treatment and prognosis.</p><p><b>RESULTS</b>Clinical manifestations were complicated. The 2 patients were mis diagnosed before operation. Their tumors consisted of irregular nests of small and round cells, with nuclear hyperchromatism and scant cytoplasm embedded in a plenty of fibrous connective tissues. The edge of the nest was clear, with different sizes and shapes. Immunohistochemically, the 2 patients were positive for CK or EMA, NSE, des and vim of the epithelium, nerve, muscle and interstitial. They died 9 months after operation.</p><p><b>CONCLUSIONS</b>The tumor may occur in the abdomen, pelvic cavity and other sites, with different clinical manifestations. Routine examination should be replaced by immunohistochemical test for correct diagnosis of the tumor. Prognosis of most patients is not good.</p>
