    ABSTRACT: Surgery, chemotherapy, and radiotherapy have presented with the ability of killing tumor cells, as well as damaging the immune function, which can be corrected by the immunotherapy. The purpose of this perspective cohort study was to evaluate the efficacy of postoperative immunotherapies of tumor lysate-loaded dendritic cells (DC), in vitro DC-activated T (DC-AT), and activated T cells (ATC) combined with chemotherapy on the survival of patients with operable colorectal cancer. A total of 253 patients with primary colorectal cancer resection including 181patients receiving postoperative simple chemotherapy (control group) and 72 patients receiving immunotherapies of DC, DC-AT, and ATC combined with chemotherapy during the corresponding period (immunotherapy group) were enrolled in this perspective cohort study. The survival of these patients was analyzed. The immunotherapy group presented a higher 5-year overall survival rate than the control group (75.63 vs 67.81 %, P = 0.035), as well as 3-year overall survival rate (87.07 vs 74.80 %, P = 0.045). For patients with advanced cancer (TNM stages III and IV), immunotherapy significantly promotes mean survival than control subjects (59.74 ± 3.21 vs 49.99 ± 2.54 years, P = 0.034). Patients who received more than three cycles of immunotherapies had a higher 5-year overall survival rate than those with less than three cycles (82.10 vs 69.90 %, P = 0.035). No serious adverse effect was observed in the immunotherapy group. Postoperative immunotherapies with DC, DC-AT, and ATC combination can promote the survival of patients with operable colorectal cancer (Clinical Trials, ChiCTR-OCH-12002610).

    ABSTRACT: To explore the clinical application of laparoscopy in gastrointestinal abdominal emergency. Clinical data of 44 cases with undefined acute abdomen undergoing laparoscopic surgery from October 2008 to October 2011 were analyzed retrospectively. Sixty-five cases treated by regular surgery during the same period were enrolled as controls. In laparoscopic surgery group, 42 cases were diagnosed under laparoscopy(95.5%, 42/44). Thirty-four (77.3%,34/44) patients received operation successfully after diagnosis, including 20 of total laparoscopy, 14 of assistant small incision. Compared with control group, laparoscopic group had shorter length of incision[(6.7±2.2) cm vs. (15.8±3.4) cm], less blood loss[(51.4±30.3) ml vs. (117.9±49.5) ml], faster recovery of postoperative gastrointestinal function[postoperative oral intake(15.0±6.1) d vs. (30.5±8.4) d], shorter hospital stay[(5.6±4.2) d vs. (8.4±4.8) d] (all P<0.05), lower complication rate, and less surgical cost(P>0.05). Laparoscopy is safe and effective in treating gastrointestinal abdominal emergency and therapeutic operation can be performed after a definite diagnosis.

    ABSTRACT: To explore the prognostic factors of anorectal malignant melanoma (ARMM). 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. 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. Early diagnosis and correct choice of surgical method are the keys to the treatment. Postoperative immunotherapy can prolong disease-free survival.

    ABSTRACT: The Da Vinci system is a newly developed device for colorectal surgery. With advanced stereoscopic vision, lack of tremor, and the ability to rotate the instruments surgeons find that robotic systems are ideal laparoscopic tools. Since conventional laparoscopic total mesorectal excision is a challenging procedure, we have sought to assess the utility of the Da Vinci robotic system in anterior resections for rectal cancer. Between November 2010 and December 2011, a total of 22 patients affected by rectal cancer were operated on with robotic technique, using the Da Vinci robot. Data regarding the outcome and pathology reports were prospectively collected in a dedicated database. There were no conversions to open surgery and no postoperative mortality of any patient. Mean operative time was (220 ± 46) minutes (range, 152 - 286 minutes). The median number of lymph nodes harvested was (14.6 ± 6.5) (range, 8 - 32), and the circumferential margin was negative in all cases. The distal margin was (2.6 ± 1.2) cm (range, 1.0 - 5.5 cm). The mean length of hospital stay was (7.8 ± 2.6) days (range, 7.0 - 13.0 days). Macroscopic grading of the specimen was complete in 19 cases and nearly complete in three patients. Robotic anterior resection for rectal surgery is safe and feasible in experienced hands. Outcome and pathology findings are comparable with those observed in open and laparoscopy procedures. This technique may facilitate minimally invasive radical rectal surgery.

    ABSTRACT: To analyze clinical and pathological of lymph node skip metastasis of rectal cancer and discuss the meaning of the high vascular ligation. A retrospective analysis of 207 cases for radical resection of rectal cancer was made, meanwhile the skip metastasis of the roots of the inferior mesenteric artery lymph nodes was studied. Combined with clinical data, the relevance of clinical and pathological factors with the skip metastasis was analyzed. The 207 cases of rectal cancer patients surgical resection specimen detected 2305 pieces of lymph node, the transfer of 168 patients with. The statistical analysis found that skip metastasis related with tumor differentiation (χ(2) = 113.65, P = 0.037) and depth of tumor invasion (χ(2) = 108.22, P = 0.042), but gender, age, location, size, preoperative carcinoembryonic antigen level, gross type and tissue types factors were not significantly correlation. Preoperative differentiation of cancer and tumor invasion depth assessment can help prompt the existence of lymph node skip metastasis. The assessment of the risk of skip metastasis for patients should be performed the high vascular ligation and lymph node dissection.
