Warthin's tumor (Papillary cystadenoma lymphomatosum) is a slowly growing benign tumor. It is usually found in the parotid gland but sometimes in extraparotid locations such as periparotid lymph nodes and jugular lymph nodes. We here report the case of a 65-year-old male patient with multiple neck masses. The computed tomographic scan showed multiple masses in the left parotid gland, at the left mid-neck and right upper neck. We enucleated the intraparotid mass and excised multiple neck mass. The histopathologic examination revealed Warthin's tumor, which is multifocal and is found in multisites.

PURPOSE: An individualized surveillance protocol based on stratified prognostic factors is needed for the early detection of recurrent disease. The aim of this study was to determine both the clinicopathological characteristics for early-recurring colorectal cancer and the impact on survival. METHODS: From January 1996 to September 2000, 1,504 patients with curatively resected colorectal cancer were recruited. The primary goal of this study was to evaluate the time interval until first loco-regional or distant recurrence, and the secondary goal was the last survival status. Early recurrence was defined as recurrence within the first 12 months postoperatively. Clinicopathologic data and preoperative CT records were reviewed. The follow-up period was over 48 months. RESULTS: The 5-year recurrence rate was 25.4%, and 39.5% of these were detected within the first 12 months postoperatively. In the multivariate analysis, the independent prognostic factors for early recurrence were cell differentiation (PD/MUC/SRC), lymphovascular invasion, and absence of adjuvant chemotherapy in stage III and curatively resected colorectal cancer in stage IV. Inaccurate interpretation by a low-quality CT scan resulted in a stage III cancer being understaged preoperatively. The 5-year overall survival rate according to the recurrent time interval was significantly different (early recurrence: 7.4% vs. late recurrence: 23.6%, P<0.05). The resection rate was similar in both groups (early recurrence: 22.7% vs. late recurrence: 27.6%, P=0.392). CONCLUSIONS: Colorectal cancer that recurred within 12 months showed more aggressive biologic behaviors and poor survival. Understaging caused by incomplete preoperative evaluation for disease extension may cause treatment failure.

Rheumatoid arthritis (RA) is a chronic inflammatory disease affecting the synovial membrane and causing joint damage and bone destruction. The symptoms of cricoarytenoid joint (CJ) arthritis often include hoarseness, and a sense of pharyngeal fullness in the throat. Sometimes, in cases with bilateral CJ involvement, an urgent tracheostomy might be required for acute airway obstruction. In this report, we describe a 45-years-old man suffering from voice change and aspiration due to hampered adduction of the vocal fold that was caused by RA with bilateral CJ involvement. The medication treatment for RA was carried out and the patient retrieved her normal voice after one month.

BACKGROUND AND OBJECTIVE: The transsynaptic transfer of neurotropic viruses is an effective tool for tracing chains of connected neurons because the replication of virus in the recipient neurons after transfer amplifies the "tracer signal". The purpose of study was to identify the location of spinal nucleus of the accessory nerve and the central neural pathways using Bartha strain of Pseudorabies virus (PRV-Ba), as a transsynaptic tracer. MATERIALS AND METHODS: PRV-Ba was injected into the sternocleidomastoid muscle of a rat, and the localization of PRV-Ba in the rat spinal cord and CNS was identified with light microscopic immunohistochemistry using primary antibodies against the PRV-Ba. RESULTS: Sequential tracing of retrogradely labeled cells was done. The shapes of positive immunoreactive cells were mostly ovoid or polygonal, and were shown in the spinal nucleus of the accessory nerve, nucleus ambiguus, paraventricular nucleus, and the primary motor area of cerebral cortex. CONCLUSIONS: These results showed the location of spinal accessory nucleus and the central neural pathways of spinal accessory nerve using PRV-Ba.

PURPOSE: The complication after colostomy formation may place undue hardship and emotional trauma on the ostomates. The purpose of this study was to find the effect of preoperative stoma site marking on postoperative stoma related complication. METHODS: We recruited 127 colostomy patients who underwent sigmoid or descending end colostomy, by elective operation. Transverse colostomy, loop colostomy, and emergency operation were excluded in this study. We divided the patients into two groups according to pre-operative stoma site marking by an enterostomal therapist. Postoperative stoma related complications were compared and analysed prospectively using chi-square test and paired t-test. Significance was assigned to a P value of < 0.05. RESULTS: Among 127 patients, 49 were marked preoperatively (marking group) while 78 were not marked (non- marking group). Overall stoma related complications were developed in 32 (25%) cases. Major complications including prolapse, parastomal hernia, stenosis were developed in 10 (8%) cases and minor complications including peristomal dermatitis and wound infection were developed in 22 (17%) cases. Stoma related complications were developed in 7 (14%) cases in the marking group and 25 (32%) cases in the non-marking group (P<0.05). Major complications were developed in 2 (4%) cases in the marking group and 8 (10%) cases in the non-marking group. Minor complications were developed in 5 (10%) cases in the marking group and 17 (22%) cases in the non-marking group. However, the difference in major and minor complications between the groups was not statistically significant. Of minor complications in the non-marking group, 9 (53%) cases due solely to postoperative frequent stool leakage caused by inappropriate location of the stoma. However, in the marking group, postoperative stool leakage was not observed. CONCLUSIONS: Preoperative stoma site marking by an enterostomal therapist may reduce postoperative stoma related complication. All elective procedure that result in stoma formation should be assessed and marked preoperatively.

PURPOSE: A retrospective study was performed to provide an overview of changes over time by age, stage, tumor location, and surgical therapy of colorectal cancer over the past 15 years. METHODS: We analyzed the cases 6,314 colorectal cancer patients who underwent surgery at Asan Medical Center between January 1990 and December 2004. The period was divided into three periods: 1990 to 1994, 1995 to 1999, and 2000 to 2004. We analyzed trends over time for stage, resectability, and demographic factors of colorectal cancer over the past 15 years. RESULTS: The mean age of the patients in the periods from 1990 to 1994, from 1995 to 1999, and from 2000 to 2004 were 57.1 (21~89), 57.4 (14~91), and 58.9 (15~91) years, respectively, showing an increasing tendency over time (P<0.001). The male-to-female ratios were 1.2 : 1, 1.3 : 1, and 1.6 : 1, repectively, and this male preponderance has been more marked in recent years (P=0.003). There was no change in tumor location over time. The ratios of early cancer to advanced cancer were 0.06 : 1, 0.09 : 1, and 0.11 : 1, respecfively, showing an increasing tendency over time (P=0.002). The curative resection rate increased over time (P<0.001). The non-curative resection rate was higher and the non-resected rate was lower in the period 2000 to 2004 than in the period 1990 to 1999 (P<0.001). The ratios of the lowest anterior resection to the abdominoperineal resection were 0.06 : 1, 0.49 : 1, and 1.02 : 1, respectively. With decreasing tendency of abdominoperineal resection, the lowest anterior resection rate has increased gradually over time (P<0.001). CONCLUSIONS: Etiologic studies are necessary to understand the male preponderance in colorectal cancer, and multi-center studies should be conducted to understand the changing trend of colorectal cancer in Korea.

PURPOSE: Anastomotic leakage (AL) is a serious and life-threatening complication following rectal cancer surgery. The impact on long-term oncologic outcome in patients with AL is not clear. The aim of this retrospective study was to evaluate the risk factors of AL and its impact on long-term prognosis after rectal cancer surgery. METHODS: We investigated 1,391 patients who underwent primary resection and anastomosis for rectal cancer between January 1997 and August 2003. Operations were performed as follows: AR (n=164), LAR (n=898), uLAR (n=329). Standard procedures in our clinic were mesorectal excision according to tumor location and autonomic nerve preservation. Median follow-up period was 40.1 months (2~96 months). RESULTS: AL rate was 2.5% (n=35). Gender (male), age (>60 years) and uLAR were independent risk factors in multivariate analysis (HR: 3.03, 95% CI: 1.18~7.22; HR: 2.42, 95% CI: 1.12~7.83; HR: 2.68, 95% CI: 1.08~7.09, respectively). Local recurrence in the AL group was significantly higher than that in the non-AL group (P<0.05), but there was no significant difference in multivariate analysis (P=0.14). Systemic recurrence between both groups was not statistically different. The 5-year overall survival rate was significantly lower in the AL group than in the non-AL group (55.1% vs 74.1%, P<0.05) and the cancer- specific survival rate was lower in the AL group than in the non-AL group (63.0% vs 78.3%, P=0.05). CONCLUSIONS: Age, gender, and anastomotic level were risk factors for AL after rectal cancer surgery and anastomotic leakage was associated with a poor survival.

Purpose: The oncological safety of a sphincter-saving resection (SSR) in lower rectal cancer is widely accepted, and both an abdominoperineal resection (APR) and a SSR are used in potentially curative surgery. This retrospective study was performed to compare the long-term oncological outcomes after an APR and a SSR in patients with lower rectal cancer (within 5 cm from the anal verge). Methods: We recruited 441 lower rectal cancer patients who underwent curative resections (APR: 305, SSR: 136) between 1995 and 2000. A total mesorectal excision and autonomic nerve preservation were routinely performed. The median follow- up period was 65 months. Results: Most demographic findings were comparable between the groups; however, the APR groups revealed more advanced pathological characteristics (tumor depth, size, cell differentiation, and metastatic LN number). The local recurrence rates after an APR and a SSR were 12.8% and 7.4%, respectively (P= 0.09). An independent risk factor of local recurrence was LN metastasis only. Distant recurrence was higher in the APR group (26.4%) than in the SSR group (13.2%), but on multivariate analysis the difference was not significant (P=0.17). The 5-year cancer-specific survival rates after an APR and a SSR were 73.2% and 87.6%, respectively (P<0.05). Particularly, there was a significant survival difference for stage III patients (APR: 59.0% vs. SSR: 83.0%, P<0.05). However, an APR was not an independent prognostic factor for cancer-specific survival in the multivariate analysis (P=0.07). Conclusions: An APR per se did not influence local recurrence after a curative resection for lower rectal cancer. The poor cancer-specific survival in the stage III APR group might be attributed to increased distant metastasis due to its more distal location.
