RESUMO

<p><b>OBJECTIVE</b>To explore the prognostic factors of anorectal malignant melanoma (ARMM).</p><p><b>METHODS</b>Medical records and follow-up data of 34 patients with ARMM treated in the Chinese PLA General Hospital from March 1993 to November 2011 were analyzed retrospectively.</p><p><b>RESULTS</b>There were 26 abdominoperineal resections(APR) and 8 wide local excisions (WLE). Twenty patients underwent postoperative adjuvant therapy, including chemotherapy in 14 cases, radiotherapy in 2 cases, traditional Chinese medicine therapy in 4 cases and immunotherapy in 16 cases. Postoperative follow-up was carried out in all the patients and the mean follow-up period was 27 months. The 1-, 3- and 5-year overall survival rates were 76.3%, 39.6% and 20.6% respectively, while the 1-, 3- and 5-year disease-free survival rates were 60.6%, 30.8% and 12.8% respectively. APR and postoperative immunotherapy could significantly reduce the local recurrence rate. According to the Kaplan-Meier method, gross type of tumor, mural involvement, lymph metastasis, and clinical staging had significant effects on overall survival, while lymph metastasis and postoperative immunotherapy on disease-free survival. Cox proportional hazards model indicated that the clinical staging and postoperative immunotherapy were significant predictive factors.</p><p><b>CONCLUSIONS</b>Early diagnosis and correct choice of surgical method are the keys to the treatment. Postoperative immunotherapy can prolong disease-free survival.</p>

RESUMO

<p><b>OBJECTIVE</b>To assess the value of preoperative neutrophil-lymphocyte ratio (NLR) for prognosis in patients with colorectal cancer after radical operation.</p><p><b>METHODS</b>Clinical data of 140 patients with colorectal cancer undergoing radical operation in the Department of General Surgery of General Hospital of PLA from July 2005 to July 2011 were analyzed retrospectively. According to preoperative NLR, patients were divided into the low NLR group (NLR<5, n=105) and the high NLR group (NLR≥5, n=35). The overall 5-year survival rates of two groups were compared and the independent risk factors were examined by univariate analysis and Cox model.</p><p><b>RESULTS</b>The overall 5-year survival rates of the low and high NLR groups were 74.8% and 54.7% respectively with significant difference (P=0.03). Univariate analysis revealed depth of tumor, lymph nodes metastasis, TMN stage and NLR were associated with survival (P<0.05, P<0.01). Cox model showed that NLR was independent risk factor of prognosis (RR=1.068, 95%CI:1.009-1.129, P=0.02).</p><p><b>CONCLUSION</b>Preoperative NLR≥5 predicts poorer prognosis of colorectal cancer patients.</p>
