OBJECTIVE: The aim of this study was to estimate the survival impact of lymphadenectomy in patients diagnosed with uterine clear cell cancer (UCCC). METHODS: Patients with a diagnosis of UCCC were identified from Surveillance, Epidemiology, and End Results (SEER) program from 1988 to 2007. Only surgically treated patients were included. Statistical analysis using Student t-test, Kaplan-Meier survival methods, and Cox proportional hazard regression were performed. RESULTS: One thousand three hundred eighty-five patients met the inclusion criteria; 955 patients (68.9%) underwent lymphadenectomy. Older patients (> or =65) were less likely to undergo lymphadenectomy compared with their younger cohorts (64.3% vs. 75.9%, p<0.001). The prevalence of nodal metastasis was 24.8%. Out of 724 women who had disease clinically confined to the uterus and underwent lymphadenectomy, 123 (17%) were found to have nodal metastasis. Lymphadenectomy was associated with improved survival. Patients who underwent lymphadenectomy were 39% (hazard ratio [HR], 0.61; 95% confidence interval [CI], 0.52 to 0.72; p<0.001) less likely to die than patient who did not have the procedure. Moreover, more extensive lymphadenectomy correlated positively with survival. Compared to patients with 0 nodes removed, patients with more extensive lymphadenectomy (1 to 10 and >10 nodes removed) were 32% (HR, 0.68; 95% CI, 0.56 to 0.83; p<0.001) and 47% (HR, 0.53; 95% CI, 0.43 to 0.65; p<0.001) less likely to die, respectively. CONCLUSION: The extent of lymphadenectomy is associated with an improved survival of patients diagnosed with UCCC.

BACKGROUND/AIMS: Gastric lymphoepithelioma-like carcinoma (LLC) is a rare cancer that presents with a unique histologic pattern that is characterized by poorly differentiated malignant cells infiltrating the background stroma along with massive lymphocyte infiltration. Many studies have shown that gastric LLC is associated with better prognosis than other gastric malignancies. However, the reason for better prognosis has not been clarified and the underlying mechanism remains to be elucidated. Therefore, we attempted to determine the clinical characteristics of gastric LLC and identify its prognostic factors related to improved survival. METHODS: A total of 18 patients were diagnosed with gastric LLC after resection from 2005 to 2012 at Department of Gastroenterology in Chungnam National University Hospital. The data of these patients were compared with 36 age- and sex-matched patients with poorly differentiated gastric adenocarcinoma who also underwent resection during the same study period. RESULTS: Postoperative recurrence or metastasis tended to occur less frequent in gastric LLC than in poorly-differentiated gastric adenocarcinoma. Among prognostic factors, only the number of lymph node metastases showed significant difference, with gastric LLC being associated with a smaller number of lymph node metastases. Regarding the disease free and overall survival rate, both were higher for gastric LLC than for poorly-differentiated gastric adenocarcinoma, albeit not statistically significant (p=0.089 and p=0.159, respectively). CONCLUSIONS: Poorly differentiated gastric adenocarcinoma was associated with a higher number of lymph node metastases at diagnosis than gastric LCC. Other potential factors affecting prognosis were not significantly different between the two cancer types.

OBJECTIVETo investigate the clinical features and treatment of anal canal adenocarcinoma.
METHODSClinical data of 49 patients with anal canal adenocarcinoma treated in our hospital from January 1965 to March 2002 were analyzed retrospectively.
RESULTSThe ratio of male to female was 1.3. The median age was 56 years old. Anal bleeding, tapering stool and anal lump were the most common symptoms. Chronic perianal diseases were complicated in 36.7% of the cases. The median follow-up was 66 months. Local recurrence and inguinal lymph node metastasis were found in 7 cases respectively, lung metastasis in 2, supraclavicular and mediastinal metastasis in 1 respectively. The 3-year survival rates in the patients with resection alone, radiochemotherapy alone, resection combined with radiochemotherapy, and without any treatment were 41.3%, 20.0%, 56.3% and 15.0%, respectively, and the 5-year survival rates were 34.4%, 0, 37.5%, 0, respectively.
CONCLUSIONSAnal canal adenocarcinoma is a rare and fatal malignancy. Abdomino-perineal resection combined with postoperative radiochemotherapy is the principal treatment.

Hypoxia-inducible factor-1 alpha (HIF-1α) plays a vital role in the initiation, evaluation and prognosis in lung cancer. The prognostic value of HIF-1α reported in diverse study remains disputable. Accordingly, a meta-analysis was implemented to further understand the prognostic role of HIF-1α in lung cancer. The relationship between HIF-1α and the clinicopathological characteristics and prognosis of lung cancer were investigated by a meta-analysis. PubMed and Embase were searched from their inception to January 2015 for observational studies. Fixed-effects or random-effects meta-analyses were used to calculate odds ratios and 95% confidence intervals of different comparisons. A total of 20 studies met the criteria. The results showed that HIF-1α expression in lung cancer tissues was significantly higher than that in normal lung tissues. Expression of HIF-1α in patients with squamous cell carcinoma was significantly higher than that of patients with adenocarcinomas. Similarly, non-small cell lung cancer (NSCLC) patients had higher HIF-1α expression than small cell lung cancer (SCLC) patients. Moreover, lymph node metastasized tissues had higher HIF-1α expression than non-lymph node metastasized tissues. A high level HIF-1α expression was well correlated with the expression of vascular endothelial growth factor and epidermal growth factor receptor in the NSCLC. Notably, NSCLC or SCLC patients with positive HIF-1α expression in tumor tissues had lower overall survival rate than patients with negative HIF-1α expression. It was suggested that HIF-1α expression may be a prognostic biomarker and a potential therapeutic target for lung cancer.

BACKGROUND/AIMS: Primary non-ampullary duodenal adenocarcinomas (PNADAs) comprise <0.3% of gastrointestinal malignancies. The rarity of PNADA and poorly defined natural history often leads to a delayed correct diagnosis. This study was conducted to evaluate the clinical characteristics of PNADA and to identify its prognostic factors. METHODS: Data were collected by retrospectively reviewing the medical records of patients with PNADA managed at Gyeongsang National University Hospital from January 2000 to December 2014. Demographic, clinical, endoscopic, and pathological variables were investigated, and factors related to survival were analyzed. RESULTS: Twenty-seven patients with PNADA were identified, and their median age was 64.9+/-13.6 years with 16 (59.3%) being male. The majority of patients (25/27, 92.6%) were initially diagnosed during upper endoscopy with biopsies. The tumor was located on the 1st or 2nd portion of duodenum in 92.6% (25/27) of patients. At the time of diagnosis, 85.2% (23/27) had advanced diseases (stage III or IV); 48.2% (13/27) had distant metastasis. Median survival time was 12 months (1-93 months). One and 3-year survival rates were 48.1% and 33.3%, respectively. On multivariable analysis, total bilirubin > or =2 mg/dL (OR, 85.28; 95% CI, 3.77-1,938.79; p=0.005) and distant metastasis (OR, 26.74; 95% CI, 3.13-2,328.14; p=0.003) at the time of diagnosis were independent poor prognostic factors. CONCLUSIONS: The majority of patients were diagnosed at an advanced stage. Presence of distant metastasis was independent prognostic factor of PNADA together with elevated total bilirubin.

BACKGROUND:
Recently, the detectable rate of ground-glass opacity (GGO ) was significantly increased, a appropriate diagnosis before clinic treatment tends to be important for patients with GGO lesions. The aim of this study is to validate the ability of the mean computed tomography (m-CT) value to predict tumor invasiveness, and compared with other measurements such as Max CT value, GGO size, solid size of GGO and C/T ratio (consolid/tumor ratio, C/T) to find out the best measurement to predict tumor invasiveness.
METHODS:
A retrospective study was conducted of 129 patients who recieved lobectomy and were pathological confirmed as atypical adenomatous pyperplasia (AAH) or clinical stage Ia lung cance in our center between January 2012 and December 2013. Of those 129 patients, the number of patients of AAH, AIS, AIS and invasive adenocarcinoma were 43, 26, 17 and 43, respectively. We defined AAH and AIS as noninvasive cancer (NC), MIA and invasive adenocarcinoma were categorized as invasive cancer(IC). We used receiver operating characteristic (ROC) curve analysis to compare the ability to predict tumor invasiveness between m-CT value, consolidation/tumor ratio, tumor size and solid size of tumor. Multiple logistic regression analyses were performed to determine the independent variables for prediction of pathologic more invasive lung cancer.
RESULTS:
129 patients were enrolled in our study (59 male and 70 female), the patients were a median age of (62.0±8.6) years (range, 44 to 82 years). The two groups were similar in terms of age, sex, differentiation (P>0.05). ROC curve analysis was performed to determine the appropriate cutoff value and area under the cure (AUC). The cutoff value of solid tumor size, tumor size, C/T ratio, m-CT value and Max CT value were 9.4 mm, 15.3 mm, 47.5%, -469.0 HU and -35.0 HU, respectively. The AUC of those variate were 0.89, 0.79, 0.82, 0.90, 0.85, respectively. When compared the clinical and radiologic data between two groups, we found the IC group was strongly associated with a high m-CT value, high Max CT value, high C/T ratio and large tumor size. Gender, solid tumor size, tumor size, C/T ratio, m-CT value and MaxCT value were selected factor for multivariate analysis, when using the preoperatively determined variables to predict the tumor invasiveness, revealed that tumor size, C/T ratio, m-CT value and Max CT value were independent predictive factors of IC.
CONCLUSIONS
The musurements of Max CT value, GGO size, solid size of GGO and C/T ratio were significantly correlated with tumor invasiveness, and the evaluation of m-CT value is most useful musurement in predicting more invasive lung cancer.

PURPOSE: Because of the rarity of primary duodenal adenocarcinomas, the factors affecting the management and survival of patients with this disease remain controversial. This study analyzed the nineteen-years of experience gained at one institution to define the surgical management and outcomes of patients with primary duodenal adenocarcinomas. METHODS: A retrospective review of 77 patients, who underwent surgery for a primary duodenal adenocarcinoma at Seoul National University Hospital, between May 1985 and April 2004, was undertaken. The dermographics symptoms, operative variables, surgical pathology and survival data were analyzed. RESULTS: A curative resection was performed in 40 patients (51.9%); a pancreaticoduodenectomies and/or resection of other organs, pancreas head resection with a duodenal segmentectomy and a segmental duodenectomy and resection of another organ in 37, 2 and 1, respectively. The remaining 37 patients underwent a palliative resection or bypass. The hospital mortality and complication rates were 2.6% (2 patients) and 42.9% (33 patients), respectively. The overall 5-year survival was 26.8%. The 5-year survival for the curative resection group was 42.7%, whereas that for the palliative surgery group was 0%. In a univariate analysis, nodal metastasis was found to have a significant negative impact on survival after a curative resection (P=0.028). The patients' age, sex, operative procedure, tumor size, histologic type, differentiation and tumor depth had no influence on survival. CONCLUSION: A curative resection is associated with increased survival in patients with a duodenal adenocarcinoma. Following a curative resection, nodal metastasis is an independent prognostic factor. Therefore, the early diagnosis should be sought to achieve a curative resection and increased survival. As a curative resection, a pancreaticoduodenectomy is usually required, and a segmental duodenal resection may be appropriate in selected patients, especially in early duodenum cancer.

We present a recurrence prediction model using multiple clinical parameters in patients surgically treated for non-small cell lung cancer. Among 1,578 lung cancer patients who underwent complete resection, we compared the early-recurrence group with the 3-yr non-recurrence group for evaluating those factors that influence early recurrence within one year after surgery. Adenocarcinoma and squamous cell carcinoma were analyzed independently. We used multiple logistic regression analysis to identify the independent clinical predictors of recurrence and Cox's proportional hazard regression method to develop a clinical prediction model. We randomly divided our patients into the training and test subsets. The pathologic stages, tumor cell type, differentiation of tumor, neoadjuvant therapy and age were significant factors on the multivariable analysis. We constructed the model for the training set with adenocarcinoma (n=236) and squamous cell carcinoma (n=305), and we applied it to the test set with adenocarcinoma (n=110) and squamous cell carcinoma (n=154). It was predictive for the in adenocarcinoma (P<0.001) and the squamous cell carcinoma (P=0.037), respectively. Our results showed that our recurrence prediction model based on the clinical parameters could significantly predict the individual patients who were at high risk or low risk for recurrence.

BACKGROUND: Small bowel tumors are relatively uncommon, accounting for only 3 to 6% of all gastrointestinal tumors. Their infrequency and the lack of specific symptoms can result in delayed diagnosis and poor prognosis. The purpose of this study was to find a relationship between the pathology and the clinical features of primary tumors of the jejunum and the ileum. METHODS: We analyzed the clinicopathological findings of 28 patients with primary tumors of the jejunum and the ileum who had undergone surgery at the Department of Surgery, Asan Medical Center, between June 1989 and December 1997. RESULTS: Among the 28 patients, there were 20 men and 8 women. The mean age was 54 years (13-76 years). The tumors consisted of 10 malignant gastrointestinal stromal tumors (GISTs), 7 lymphomas, 6 benign GISTs, 3 adenocarcinomas, and 2 lipomas. The clinical symptoms of these patients were abdominal pain (54%), GI bleeding (32%), nausea & vomiting (14%), weight loss (14%), palpation of abdominal mass (11%), and dizziness (11%). The preoperative complications were bleeding (32%), perforation (18%), intussusception (11%), and obstruction (7%). Bleeding was found in GISTs only and was more frequent in benign GISTs(100%) than in malignant GISTs (30%). Perforation was found in malignant tumors only (25%). Among the 20 patients with malignant tumors, chemotherapy was done in 13, and the 2-year survival rate was 75%. CONCLUSIONS: Early diagnosis of small bowel tumors is essential to prevent complications such as bleeding and perforation and to reduce mortality. Early diagnosis and surgery seem to be indispensable to a good outcome in symptomatic patients.

OBJECTIVETo investigate the clinicopathological characteristics, diagnosis, treatment and prognosis of patients with primary gastric adenosquamous cell carcinoma.
METHODSA total of 5 562 patients with gastric neoplasm were admitted in Tianjin Medical University Cancer Institute and Hospital from January 2001 to January 2011. Among them 42 patients were diagnosed as primary gastric adenosquamous cell carcinoma, accounting for 0.76% of all the patients. The clinicopathological and follow-up data of these 42 patients with primary gastric adenosquamous cell carcinoma were retrospectively analyzed, and Cox proportional hazard model was used to analyze the prognostic factors of gastric adenocarcinoma squamous cell carcinoma.
RESULTSAmong above 42 patients, 32 were male and 10 were female, with a male-to-female ratio of 3.2/1.0 and the average age was 63 years (range: 46 to 77 years). Five patients (11.9%) were confirmed as adenosquamous cell carcinoma by preoperative pathological examination, while other 37 patients were diagnosed as adenocarcinoma preoperatively. According to the 7th edition AJCC TNM classification system for gastric adenocarcinoma, 5 patients (11.9%) were in stage II(, 30 patients (71.4%) in stage III( and 7 patients (16.7%) in stage IIII(. The maximum tumor diameter was > 5 cm in 18 patients (42.9%). Borrmann type III(-IIII( was found in 29 patients (69.0%), and poorly differentiated (or undifferentiated) tumor was found in 32 patients (76.2%). Radical operations were performed in 31 patients (73.8%), the reasons of non radical operations included infiltration of pancreas in 3 patients, infiltration of radices mesocili transvers in 1 patient and classification of stage IIII( in 7 patients. Lymph node dissection was performed in 37 patients, 83.8% of them (31/37) was found with lymphatic metastases. Twenty-five patients received adjuvant chemotherapy except for 7 patients in stage IIII( and 10 patients who refused adjuvant chemotherapy. All the patients had an average survival time of 36.4 months and median survival time of 28.0 months, and the overall 1-, 3- and 5-year survival rates were 82.2%, 42.3% and 18.2% respectively. Univariate analysis revealed that tumor size (χ=4.039, P=0.044), Borrmann type (χ=18.728, P=0.000), tumor differentiation (χ=19.612, P=0.000), radical gastectomy (χ=41.452, P=0.000), lymph node metastasis (χ=9.689, P=0.002) and clinical stage (χ=26.277, P=0.000) were associated with postoperative survival. Multivariate analysis revealed that tumor differentiation (HR=10.560, 95%CI:2.263-49.281, P=0.003), radical gastrectomy (HR=4.309, 95%CI:1.311-14.168, P=0.016) and clinical stage (HR=2.392, 95%CI:1.022-5.600, P=0.044) were independent prognosis factors.
CONCLUSIONSPrimary gastric adenosquamous cell carcinoma is rare with poor prognosis. Radical gastrectomy is recommended. Tumor differentiation, radical gastrectomy and clinical stage are important indicators to evaluate prognosis of primary gastric adenosquamous cell carcinoma.
