OBJECTIVETo raise the awareness of adenosquamous carcinoma of pancreas and discuss the treatment of it.

METHODSClinical data of 80 cases of pancreas adenosquamous carcinoma patients in the Department of Pancreas Surgery of Changhai Hospital of Second Military Medical University from December 2003 to October 2011 were analyzed. The diagnose and treatment methods were discussed. There were 61 male cases and 19 female cases who aged from 28 to 81 years, with an average age of 60 years. The primary symptoms included 46 cases (57.5%) of abdominal malaise, 6 cases (7.5%) of low back pain, 4 cases (5.0%) of abdominal swelling pain with low back pain, 15 cases (18.8%) of abdominal swelling pain with jaundice, 5 cases (6.3%) of painless jaundice, 3 cases (3.8%) of significantly decreased body-weight and 1 case (1.3%) of no symptom. All the patients had been identified as pancreas tumor suffers by ultrasound, enhanced CT scan or MRI. Totally there were 43 cases of head/unciform process tumors, 15 cases of pancreas body tumors and 22 pancreas tail cases.Health situation of all cases were follow-up observed in the outpatient department or telephoned every 3 months till 24 months after the surgery.

RESULTSAmong the 80 patients, 19 patients underwent pancreaticoduodenectomy (PD) , 19 patients received pylorus-preserving PD, with 4 cases of palliative resection and 1 case of total pancreatectomy. The volume of bleeding during the surgery varied from 50 to 3 500 ml with a blood transfusion volume varied from 0 to 4 000 ml. Consumed time for PD procedures was 90 to 260 min with 60 to 150 min for body and (or) tail resection with or without lienectomy. The mean diameter of tumor was (4.9 ± 2.2) cm. Pathological tests showed 35 cases of positive lymph nodes, adjacent organ invasion happened in 35 patients, however, nerve invasion were found in 68 cases.Eighteen cases occurred postoperative complications, including bleeding, pancreatic fistula, gastric emptying, incision fat liquefaction and infection, pleural effusion, ascites and nervous diarrhea. There were only 48 effective follow-up patients, with a loss ratio of follow-up by 40.0%, reasons for the loss includes change of contact information, refuse or unable to provide useful information by the relatives of the patients.Sixteen patients received chemotherapy, and 8 patients received radiotherapy after operation. All patients were dead in the effective follow-ups. The postoperative median survival time was 6 months (0.1 to 23.0 months).

CONCLUSIONSAdenosquamous carcinoma of pancreas is a rare kind of malignant tumor, nerve invasion can be found in almost all the cases. Patients with adenosquamous carcinoma of pancreas have an unfavorable prognosis. The principle treatments are surgery, radiotherapy and chemotherapy.

OBJECTIVE: A prospective, randomized controlled trial was conducted to evaluate the efficacy of nerve-sparing radical hysterectomy (NSRH) in preserving bladder function and its oncologic safety in the treatment of cervical cancer. METHODS: From March 2003 to November 2005, 92 patients with cervical cancer stage IA2 to IIA were randomly assigned for surgical treatment with conventional radical hysterectomy (CRH) or NSRH, and 86 patients finally included in the analysis. Adequacy of nerve sparing, radicality, bladder function, and oncologic safety were assessed by quantifying the nerve fibers in the paracervix, measuring the extent of paracervix and harvested lymph nodes (LNs), urodynamic study (UDS) with International Prostate Symptom Score (IPSS), and 10-year disease-free survival (DFS), respectively. RESULTS: There were no differences in clinicopathologic characteristics between two groups. The median number of nerve fiber was 12 (range, 6 to 21) and 30 (range, 17 to 45) in the NSRH and CRH, respectively (p<0.001). The extent of resected paracervix and number of LNs were not different between the two groups. Volume of residual urine and bladder compliance were significantly deteriorated at 12 months after CRH. On the contrary, all parameters of UDS were recovered no later than 3 months after NSRH. Evaluation of the IPSS showed that the frequency of long-term urinary symptom was higher in CRH than in the NSRH group. The median duration before the postvoid residual urine volume became less than 50 mL was 11 days (range, 7 to 26 days) in NSRH group and was 18 days (range, 10 to 85 days) in CRH group (p<0.001). No significant difference was observed in the 10-year DFS between two groups. CONCLUSION: NSRH appears to be effective in preserving bladder function without sacrificing oncologic safety.
