BACKGROUND/AIMS: After colorectal cancer surgery, colonoscopic surveillance should be done for prevention and early detection of secondary cancer. This study aimed to identify the group with high risk of developing colorectal adenoma after curative surgery of colorectal cancer. METHODS: We retrospectively investigated the medical records of the subjects of 130 patients who had been examined using colonoscopy before and after the curative surgery. RESULTS: The average age was 59.4 years. Synchronous adenomas were in 42 patients (32.3%). The occurrence rate was significantly high in men (38.8%) than women (22.0%). After the operation, the mean interval of examining colonoscopy was 11.6 months (3-24 months) and metachronous adenomas were detected in 26 patients (20.0%). The patients who have both metachronous and synchronous adenomas were observed in 13/42 (30.9%) and the patients of metachronous adenomas without synchronous adenomas were observed in 13/88 (14.8%). The occurrence rate of metachronous adenomas with synchronous adenomas was significantly high. The frequency of synchronous adenomas didn't increase with age. However, the frequency of metachronous adenomas increased with age: 0/9 (0%) under 40 years, 7/49 (14.3%) in 41-61 years and 19/72 (26.4%) over 61 years. The occurrence rate was higher in men (26.3%) than women (10.0%). CONCLUSIONS: The occurrence rate of metachronous adenomas after colorectal cancer surgery was higher in the patients with synchronous adenomas, male gender and old aged patients.

BACKGROUND/AIMS: Synchronous/metachronous gastric epithelial neoplasias (GENs) in the remaining lesion can develop at sites other than the site of endoscopic resection. In the present study, we aimed to investigate the predictive value of serum pepsinogen for detecting multiple GENs in patients who underwent endoscopic resection. METHODS: In total, 228 patients with GEN who underwent endoscopic resection and blood collection for pepsinogen I and II determination were evaluated retrospectively. RESULTS: The mean period of endoscopic follow-up was 748.8+/-34.7 days. Synchronous GENs developed in 46 of 228 (20.1%) and metachronous GENs in 27 of 228 (10.6%) patients during the follow-up period. Multiple GENs were associated with the presence of pepsinogen I <30 ng/mL (p<0.001). Synchronous GENs were associated with the presence of pepsinogen I <30 ng/mL (p<0.001). CONCLUSIONS: Low pepsinogen I levels predict multiple GENs after endoscopic resection, especially synchronous GENs. Cautious endoscopic examination prior to endoscopic resection to detect multiple GENs should be performed for these patients.

Endoscopic submucosal dissection (ESD) is an useful therapeutic technique for large gastrointestinal epithelial tumors that it provides an en bloc resection. Although there is some controversy about the role of ESD for colorectal lesions, for large lesions in the distal rectum, ESD has the advantage of preserving anal function. However, the large amount of insufflating gas used during the procedure can cause severe abdominal pain and discomfort. Moreover, high intra-luminal pressure caused by a by large amount of gas can cause a micro-perforation. There is no consensus as to whether ESD is the optimal treatment for synchronous large colorectal laterally spreading tumors (LSTs) that cannot be removed en-bloc by conventional endoscopic mucosal resection. Here, a case with two neighboring synchronous large LSTs, one located in the rectum and the other in the distal sigmoid colon, were sequentially removed by separate ESD procedures performed on two consecutive days in a patient who could not tolerate a long procedure.

OBJECTIVETo analyze the clinical features of facial nerve neuroma about its diagnosis and management.

METHODSTen patients with facial nerve neuroma were analyzed retrospectively from February 1993 to August 2005. The period of follow-up varied from 1.5 years to 10 years (mean 5 years). Facial nerve function was evaluated with House-Brackmann grading system.

RESULTSThe patients complained of facial paralysis in 7 cases, otitis media in 1 case, a mass in parotid gland in 1 case and a mass on the side of the orbital on face in 1 case. Seven patients were undergone either CT scan or MRI or both. Image studies revealed mass located along the facial nerve course from the nerve endings to the intracranial parts. All the patients accepted the surgery. Intraoperative findings showed that the tumor location matched the image findings. Postoperative pathological diagnosis demonstrated 8 Schwannoma, 2 neurofibroma. There was partial tumor resection in 1 patient accepted and his nerve function was unchanged. Four patients were undergone facial nerve graft but 1 case failed while facial nerve function was improved in 3 other patients. Two patients underwent tumor resection while the continuity of facial nerve was preserved as result their facial nerve function improved respectively. No facial nerve reconstruction was done on other 2 patients.

CONCLUSIONSMultiple origins of facial nerve neuroma were noted and the most common system was facial nerve palsy. The decision on how to treat these patients should be individualized and based on initial facial function, growth rate, surgical experience and informed patient consent. The more effective methods need being seeked for the management of facial nerve neuroma.

BACKGROUND/AIMS: Guidelines for current postoperative colonoscopic surveillance are not specified in colorectal cancer (CRC) patients with synchronous adenoma (SA). We performed this retrospective study to determine the postoperative colonoscopic surveillance interval for the CRC patients with SA. METHODS: One hundred and twenty-four CRC patients with SA (SA-group) and the same number of patients without SA (NSA-group) were selected from our database. Two groups were matched by the stage of CRC. Median colonoscopic surveillance period was 55 (12-99) months. The colonoscopic surveillance frequency and interval were similar between the two groups. RESULTS: Mean age was higher and male was more frequent in SA-group than NSA-group (p= 0.0001). The incidence of missed adenoma, advanced missed adenoma and metachronous adenoma (MA) were higher in SA-group (30.8% vs. 5.8% at 1st yr., p=0.0001; 4.4% vs. 0%, p=0.0001; 31.1% vs. 9.1% at 2nd yr., p=0.016) during the first consecutive two years of surveillance. The MA- and advanced-MA-free survival rate were lower in SA-group (24.6% vs. 6.6%, p=0.0001; 4.1% vs. 0%, p=0.02) during three years after surgery. Dysplasia of the SA (p=0.04; OR, 110.3; 95% CI, 1.13-10742.6) and presence of missed adenoma (p=0.036; OR, 43.6; 95% CI, 1.28-1490.1) were risk factors for the advanced MA on a multivariate analysis in SA-group. CONCLUSIONS: Postoperative colonoscopic surveillance at first year after surgery is warranted in CRC patients with SA.

OBJECTIVETo study the incidence rate of multiple primary colorectal carcinomas (MPCC) in colorectal carcinoma and to evaluate its clinical and pathological characteristics.

METHODSOne hundred and sixty-eight (4.6%) patients from 3663 cases with colorectal carcinoma were diagnosed with MPCC from January 1985 to December 2003. The clinical data of the patients were collected retrospectively to investigate the diagnosis and treatment of MPCC.

RESULTSOf the 168 patients, 81 were diagnosed as synchronous colorectal carcinoma (SC), 72 with metachronous colorectal carcinoma (MC), 15 with both SC and MC. The median age at time of diagnosis of colorectal carcinoma was 58 years old (range from 20 to 82 years old). Three hundred and ninety-three cancer lesions were detected in these 168 cases (mean, 2.3 lesions/case). The rectum and sigmoid colon were the most involved sites (61.6%). Eighteen cases (10.7%) were verified with hereditary non-polyposis colorectal cancer (HNPCC) while another 9 cases were highly suspected. Fourteen patients (8.3%) were found with other malignancies out of large intestine, 41 patients (24.4%) with colorectal adenomas, 72 (42.9%) with adenoma carcinogenesis. Among the 96 SC patients, 91 were given preoperative colonoscopy and 65 (71.4%) got the diagnosis. All the MC patients were diagnosed by postoperative colonoscopy. The overall 5-year survival rate of the 168 patients was 69.8%.

CONCLUSIONSMPCC should be paid more attention in colorectal cancer management. Colonoscopic surveillance is much more important in diagnosis and follow-up of MPCC for reducing the misdiagnosis of SC and detecting more MC in time. Prompt treatment of adenoma can reduce the occurrence of MPCC, and active and standard surgical treatment should be done for MPCC.

BACKGROUND: Simultaneity multiple primary lung cancer always is a rare disease, but in recent years due to the progress of the diagnosis and treatment means detection rate increased. This study summarized the clinical data of 31 cases of synchronous multiple primary lung cancer (sMPLC) analysis, further to explore the diagnosis, treatment and prognosis of MPLC. METHODS: Sum up the clinical data of 31 cases of simultaneous multiple primary lung cancer, the diagnostic method, surgical methods, pathology, were retrospectively analyzed. RESULTS: All the patients are thoracoscope surgery, no deaths. Thin high resolution computed tomography (CT) in preoperative found multiple lung nodules. Lesions located in the same side of the same period surgical treatment, the operation method is given priority to with under the thoracoscope lung + the lobectomy; Lesions located in bilateral, all staged operation, the time interval for 3 months-4 months. CONCLUSIONS Thin layer distinguish CT preoperative diagnosis is the best way to simultaneous multiple primary lung cancer. Multiple primary lung cancer incidence of ipsilateral lung at the same time higher than that of bilateral lung (23:8), type, around 94%, the most common histology to adenocarcinoma, 80.6% (25/31). Primary lesions under thoracoscope lobectomy plus the lobectomy of secondary lesions is the most commonly used.

OBJECTIVETo study the clinical features and proper treatment of 38 elderly patients with early double primary cancers.

METHODSThirty-eight elderly patients with early double primary cancers treated from January 1980 to March 2003 were retrospectively reviewed for involved organs, treatment and prognosis.

RESULTSDigestive tract was the most frequently involved, followed by urogenital system and lung. Long-term results of endoscopic mucosal resection (EMR), operation and radiotherapy were superior to other methods. The prognosis of gastrointestinal carcinoma was better than that of prostate carcinoma and hematopoietic system. The operation rate decreased with increasing age. The 5-year survival rates of EMR, operation and radiotherapy were 85.7%, 71.1% and 75.0%, respectively. The medium survival time was 120 months in first cancer and 39 months in the second primary cancer. The 5-year survival rates of the first cancer and second primary cancer were 88.6% and 53.8%.

CONCLUSIONYearly follow-up for elderly patients with endoscopy, beta ultrasonic scan and X-ray contribute to finding of early double primary cancers. Operation is the best treatment of early double primary cancers. Endoscopic mucosal resection is especially suitable for old patients with digestive tract and bladder cancer.
