BACKGROUND: It is well known that the prevalence of lung cancer is higher in idiopathic pulmonary fibrosis(IPF) patients than in the general population. This high prevalence is explained by the concept of 'scar carcinoma'. There have been several reports on the prevalence of histologic type of lung cancer in IPF with conflicting results. Despite of the high smoker rate in almost all previous reports, none considered the smoking history of patients. Therefore we performed a separate studies on fibrosis associated lung cancer and smoking associated lung cancer. The purpose of this study is to investigate the proportion of lung cancer in IPF that is fibrosis assiciated and to determine the most common histologic type in fibrosis associated lung cancer in IPF. METHODS: A retrospective review of medical records and radilolgic studies was performed for cases of lung cancer with IPF. We investigated smoking history, sequence of diagnosis of lung cancer and IPF, histologic type of lung cancer and the cancer location, especially whether the location is associated with fibrosis. To evaluate the proportion of fibrous associated lung cancer, the lung cancer in IPF were categorized according to the presence of fibrosis at cancer location. RESULTS: Fifty seven patients were subjects for this analysis. Six(11%) cases were diagnosed as lung cancer during follow-up for IPF, and both diseases were diagnosed simultaneously in the others. Ninety four percent of patients were smokers and the average smoking amount was 47.1±21.9 pack-year. Among the patients with IPF and lung cancer, 42(80.8%) cases were considered as 'fibrosis associated'. The remainder was 'not fibrosis associated' and probably was due to smoking etc. Although the most frequent histologic type was squamous cell carcinoma as a whole, adenocarcinoma was the prominent histologic type in 'fibrosis associated lung cancer.' CONCLUSION: Considering the proportion of 'fibrosis not associated lung cancer' in the patients with IPF and lung cancer, significant proportion of lung cancer in IPF may not be fibrosis induced. This may influence the distribution of histologic type of lung cancer in IPF.

PURPOSE: In the present study, the effectiveness of topical chemotherapy for the primary treatment of ocular surface squamous neoplasia (OSSN) was evaluated. METHODS: We enrolled 10 patients (10 eyes) diagnosed with OSSN who received both clinical examination and anterior segment optical coherence tomography (AS-OCT) imaging. The patients were administered topical 0.02% mitomycin-C (MMC) 4 times/day in the affected eye. The patients with MMC-resistant OSSN received topical 1% 5-fluorouracil (5-FU) 4 times/day. AS-OCT imaging was performed before and after the treatment. Clinical examination and AS-OCT were used to monitor the efficacy of topical chemotherapy, recurrence and side effects. RESULTS: The mean age of the 10 patients (8 males, 2 females) was 76.7 years. The proportion of complete remission resulting from topical treatment with MMC was 80.0% (8 eyes) and 20.0% (2 eyes) when 5-FU was changed to MMC. The average duration of complete remission was 4.3 weeks and the average duration of no recurrence was 17.5 months. The epithelial thickness of the lesions, measured using AS-OCT, significantly decreased from 315.0 µm (pretreatment) to 105.3 µm (after complete remission). Additionally, the epithelial lesion appeared normal after treatment. The most common side effect was conjunctival hyperemia (60.0%, 6 eyes), followed by ocular allergy (30.0%, 3 eyes), superficial punctate keratitis (30.0%, 3 eyes) and corneal erosion (20%, 2 eyes). No serious complications were reported. CONCLUSIONS: Topical chemotherapy is as effective and well tolerated as a primary treatment for OSSN. Additionally, AS-OCT is a useful noninvasive adjunctive tool in the diagnosis and management of OSSN.

PURPOSE: Mesh non-fixation in TEP is associated with lower cost and shorter operative time, and it is safe and recommended when performed by an experienced surgeon. In performance of TEP surgery using a non-fixation mesh, particularly by a non-experienced surgeon, prevention of mesh migration is an important issue for mesh application. The aim of this study was to report on a fixation method using a non-preformed mesh encircling a cord structure without the use of tacks, staples, or fibrin sealants in TEP surgery. METHODS: A total of 41 patients who had undergone mesh-encircling TEP without fixation from December 2008 (first case of surgery) to June 2012 were analyzed. RESULTS: The mean follow-up period was 23.2 months (12~35 months). Three patients complained of scrotal discomfort, and one patient complained of scrotal edema, but they were resolved with conservative management. There was no recurrence during the follow up period. CONCLUSION: The method of mesh-encircling TEP without fixation material and no additional mesh in which the slit of the mesh is wrapped around the cord structure using an overlay suture is a simple and safe technique without compromising recurrence or chronic pain.

PURPOSE: The purpose of this study is to investigate the prognostic significance of tumor size for 5-year survival rate in patients with gastric cancer. MATERIALS AND METHODS: A total of 1,697 patients with gastric cancer, who underwent potentially curative gastrectomy, were evaluated. Patients were divided into 4 groups as follows, according to the median size of early and advanced gastric cancer, respectively: small early gastric cancer (tumor size < or =3 cm), large early gastric cancer (tumor size >3 cm), small advanced gastric cancer (tumor size < or =6 cm), and large advanced gastric cancer (tumor size >6 cm). The prognostic value of tumor size for 5-year survival rate was investigated. RESULTS: In a univariate analysis, tumor size is a significant prognostic factor in advanced gastric cancer, but not in early gastric cancer. Multivariate analysis showed that tumor size is an independent prognostic factor for 5-year survival rate in advanced gastric cancer (P=0.003, hazard ratio=1.372, 95% confidence interval=1.115~1.690). When advanced gastric cancer is subdivided into 2 groups, according to serosa invasion: Group 1; serosa negative (T2 and T3, 7th AJCC), and Group 2; serosa positive (T4a and T4b, 7th AJCC), tumor size is an independent prognostic factor in Group 1 (P=0.011, hazard ratio=1.810, 95% confidence interval=1.149~2.852) and in Group 2 (P=0.033, hazard ratio=1.288, 95% confidence interval=1.020~1.627), respectively. CONCLUSIONS: Tumor size is an independent prognostic factor in advanced gastric cancer irrespective of the serosa invasion, but not in early gastric cancer.

BACKGROUND: This study evaluated how the alcohol drinking motives and alcohol drinking expectancies, as the internal factors, would relate to university students' alcohol drinking problems. METHODS: The general characteristics, the alcohol drinking problems, the motives to drink, and drinking expectancy were surveyed with 197 university students (106 males, 91 females) who visited the Health Center of Chungnam National University. RESULTS: The alcohol drinking amount per drink (P < 0.001), weekly alcohol drinking frequency (P < 0.001), alcohol drinking problem score (P < 0.001), the score of drinking expectancy (P < 0.001) and motives to drink for each domain (P < 0.05) for male students were significantly higher or larger than those of the female students. The distribution of the number of binge, heavy and at risk drinkers didn't show significant difference between sexes. The drinking problem score, the score of drinking expectancy and motives to drink for each domain showed significant (P < 0.001) positive correlation and male students displayed a higher positive correlation than that of female. Stepwise multiple regression analysis was conducted to evaluate the influence on drinking problem score. The male students' drinking problem score was associated with the score of coping motive, lower grade, the score of enhancement motive and drinking expectancy (R2, 0.325; P < 0.05) whereas those of female students were related to the score of social and coping motive (R2, 0.477; P < 0.001). CONCLUSION: The common factor that related to drinking problem for both male and female students was the coping motive to resolve negative feeling. In addition, the enhancement motive and drinking expectancy in male students and the social motive in female students were the associated factors.

PURPOSE: The aim of this study was to compare ESD only and subsequent Laparoscopy-assisted gastrectomy (LAG) patients for EGC through propensity score matching analysis. METHODS: This study was a retrospective review of the records of 46 consecutive patients with gastric cancer who underwent LAG after ESD from 2009, September to 2014, September, and propensity matching analysis was performed with 92 patients who underwent LAG without ESD as a control group. Subgroup analysis was performed with the interval of subsequent laparoscopic gastrectomy and endoscopic resection (within 2 weeks, 2~4 weeks, above 4 weeks). RESULTS: There were no significant differences in age, gender, body mass index, comorbidity, previous abdominal surgery, and location of the lesion or clinical stage between the two groups. Early postoperative outcomes including postoperative complications and postoperative hospital stay were not significantly different between the two groups. According to subgroup analysis with the interval of laparoscopic gastrectomy and endoscopic resection, there were no significant differences in early outcomes in three groups. However, only early postoperative complication rate was significantly higher in patients who received LAG more than 4 weeks after ESD (0 versus 4.76 versus 40 per cent; p=0.0032). CONCLUSION: We analyzed the influence of ESD on subsequent LAG using propensity score matching to reduce the bias. However, we found that ESD might induce inflammation for a significant duration, but ESD had little influence on early postoperative outcome of LAG.
