It is well known that gastrectomy with curative intent is the best way to improve outcomes of patients with remnant gastric cancer. Recently, several investigators reported their experiences with laparoscopic gastrectomy of remnant gastric cancer. We report the case of an 83-year-old female patient who was diagnosed with remnant gastric cancer with obstruction. She underwent an entirely laparoscopic distal gastrectomy with colectomy because of direct invasion of the transverse colon. The operation time was 200 minutes. There were no postoperative complications. The pathologic stage was T4b (transverse colon) N0M0. Our experience suggests that laparoscopic surgery could be an effective method to improve the surgical outcomes of remnant gastric cancer patients.

Between March 1978 and December 1985, 39 patients were admitted to our hospital & surgery was performed to 27 patients. Among 39 patients, male patients were 31 cases, female 8 cases and the age ranged from 42 years old to 69 yrs old with the average of 55 years old. Main symptoms of esophageal cancer were dysphagia [6%], weight loss [20%], retrosternal and epicardial discomfort [18%], hoarseness [13%], and hiccup [5%]. The anatomical locations of esophageal cancer were followed as; 51% in lower esophagus & cardia, 44% in middle, and 5% in upper esophagus. Among 27 cases, 5 cases were managed by feeding gastrostomy and jejunostomy due to inoperability, 19 cases by esophagogastrostomy, and 3 cases by colon bypass with the resection of esophageal cancer. Postoperative complications were noticed in 7 cases, such as anastomotic leakage in 2 cases [7%], respiratory insufficiency in 2 cases [7%], intussusception in 1 case [4%], wound dehiscence in 1 case [4%], and hepatitis in 1 case [4%]. Among 2 respiratory insufficiency, 2 patients die as a result of that complication and operative mortality was 7%.

Background: Urothelial carcinoma (UC) is a malignant neoplasm that most commonly occurs in the urinary bladder. The primary aim of this study was to evaluate the clinicopathologic features, recurrence and progression in patients with bladder urothelial cancer. Materials and Methods: The medical records of patients diagnosed with UC in the state pathology laboratory between January 2006 and July 2014 were retrospectively included. Carcinomas were categorized according to age, gender, histologic grade, tumor configuration, pathologic staging, recurrence status, and progression. Results: A total of 125 (113 men, 12 women) patients were examined. The mean age was 65.9 years and the male-to-female urothelial cancer incidence ratio was 9.4:1. Low-grade UCs were observed in 85 (68%) and high-grade in 40 (32%). A papillary tumor pattern was observed in 67.2% of the UCs. Cases were classified with the following pathological grades: 34 (27.2%) cases of pTa, 70 (56%) of pT1, and 21 (16.8%) of pT2. Recurrence occurred in 27 (21.6%) patients. Ten progressed to a higher stage (pT1 to pT2), and three cases to higher grade (low to high). We also analyzed the results separately for 70 (56%) patients 65 years of age and older. Conclusions: With early detection and diagnosis of precursor lesions in older patients, by methods such as standard urologic evaluation, urinary cytology, ultrasound scanning and contrast urography, and cystoscopy, in addition to coordinated efforts between pathologists and urologists, early diagnosis may reduce the morbidity and mortality of patients with urothelial carcinoma.

This study focused on infection rates and subtypes of human papillomavirus (HPV) in patients with oropharyngeal squamous cell carcinoma (OSCC), and the relationship between HPV status and prognosis of the disease. We evaluated sixty-six OSCC patients who met the enrollment criteria during the period from January 1999 to December 2009. The presence or absence of oncogenic HPV types in tumors was determined using the SPF10 LiPA25 assay. Overall survival (OS) and disease specific survival (DSS) for HPV positive and HPV negative patients were estimated using Kaplan-Meier analysis. The Cox regression model was applied for multivariate analysis. HPV-DNA was detected in 11(16.7%) of all specimens. Among them, 7 were type HPV-16, while other types were HPV-16/11, HPV-35, HPV-58/52, and HPV-33/52/54. Patients with HPV positive tumors were more likely to be female, non-smokers and non-drinkers (p=0.002, 0.001 and 0.001, respectively). After a median follow-up of 24.5 months, patients with HPV positive tumors had significantly better overall survival (HR=0.106[95%CI=0.014-0.787], p=0.016,) and disease specific survival (HR=0.121[95%CI=0.016-0.906], p=0.030). Patients with HPV positive OSCC have significantly better prognosis than patients with HPV negative tumors. HPV infection is an independent prognostic factor.

Dose monitoring in CT patients requires accurate dose estimation but most of the CT dose calculation tools are based on Caucasian computational phantoms. We established a library of organ dose conversion coefficients for Korean adults by using four Korean adult male and two female voxel phantoms combined with Monte Carlo simulation techniques. We calculated organ dose conversion coefficients for head, chest, abdomen and pelvis, and chest-abdomen-pelvis scans, and compared the results with the existing data calculated from Caucasian phantoms. We derived representative organ doses for Korean adults using Korean CT dose surveys combined with the dose conversion coefficients. The organ dose conversion coefficients from the Korean adult phantoms were slightly greater than those of the ICRP reference phantoms: up to 13% for the brain doses in head scans and up to 10% for the dose to the small intestine wall in abdominal scans. We derived Korean representative doses to major organs in head, chest, and AP scans using mean CTDI_vol values extracted from the Korean nationwide surveys conducted in 2008 and 2017. The Korean-specific organ dose conversion coefficients should be useful to readily estimate organ absorbed doses for Korean adult male and female patients undergoing CT scans.

Background and Objectives: Nodal metastasis is one of the prognostic factors in salivary gland cancer. The purpose of this study is to identify risk factors of nodal metastasis considered as a predictor of poor prognosis in patients with salivary gland cancer. Material and Methods: The authors retrospectively studied 82 patients with salivary gland cancer who underwent surgery from 1992 to 2002. We analyzed age, sex, tumor size, histologic type and 5-year survival rate to compare patients with and without nodal metastasis. Results: Mean age was 55.4 years, with a male-female ratio of 1 : 1.28. The overall 5-year survival rate was 85.5%. Among the 82 patients, 14 patients had nodal metastasis. There was no nodal metastasis in low grade malignancy. In patients without nodal metastasis, mean age was 52.5 years and the overall 5-year survival rate was 94.2%. In patients with nodal metastasis, mean age was 69.4 years and the overall 5-year survival rate was 42.9%. In patients with less advanced cancer (T1-T2 stage), the nodal metastasis was 7.5% and with advanced cancer (T3-T4 stage), 33.3%. Conclusion: Nodal metastasis significantly decreases survival in patients with salivary gland malignancy. High grade malignancy, large tumor size and old age are important risk factors of nodal metastasis. Nodal metastasis is more common in submandibular gland cancer compared with parotid gland cancer.

Purpose: This study was to identify the level of quality of life in patients with woman cancer across treatment phases. Methods: The research method was a cross-sectional descriptive study. Data was collected by questionnaires from 226 female, who were in- and out-patients. They were diagnosed with breast and uterine cancer from three university hospitals and two general hospitals. The instruments used for this study included, "the Quality Of Life Scale(QOL)". The collected data were analyzed using Frequency, Percentage, ANOVA, Two-Way ANOVA. Results: Quality of life of women cancer patients was significantly different according to three treatment phases. Quality of life of women cancer patients was not significantly different according to areas of disease in the three treatment phases. Quality of life of women cancer patients was significantly different according to level of fatigue in the three treatment phases. Quality of life of women cancer patients was significantly different according to level of perceived health status in the three treatment phases(F=60.14, p=0.000). Quality of life of women cancer patients was significantly different according to education level(F=3.70, p=0.027) & occupation(F=5.67, p=0.018) in three treatment phases. Conclusion: Strategies for intervention are needed to improve the quality of life in women cancer patients across the treatment phases. The significant several characteristics of affecting on quality of life across treatment phases should be considered in sociopsychological nursing intervention.

Background: The aim of this research was to perform an epidemiologic survey of esophageal cancer in Ardabil province. Materials and Methods: In this cross-sectional descriptive study, 661 patients diagnosed with EC were studied from March 2002 to May 2011 e. The necessary data were collected with a checklist from the documents in Ardabil Cancer Registry (ACR) and analyzed by statistical methods with SPSS.18 software. Results: Of the total new cases of EC registered in ARC during study period, 430 (65.1%) of patients were male with the male to female standard ratio was 1.18, with a statistically significant gender bias. The most common morphology of EC was squamous cell carcinoma (SCC, 68.8%) followed by adenocarcinoma (28.5%). It was observed that in most of patients, EC lesions were in the middle third of esophagus. In addition, most patients were rural and about 40% had smoking habits. The age-standardized incidence rate of cancers was 48.4 per 100,000 among females and males. The annual incidence rates in males and females was 7.1 and 6.7 per 100,000; respectively. Conclusions: Results showed that the prevalence and annual incidence rate of cancer in Ardabil province is lower than other areas of the country with a male predominance and a relatively high proprortion of adenocarcinomas.
