Background: To study the clinical presentation of cervical carcinoma correlating with histopathological findings in a tertiary hospital situated in the southern part of India catering to rural and semi-urban populations Materials and Methods: 199 cases histopathologically diagnosed as cervical cancer over a period of one year were considered for the study. Clinical details of the patients were noted with the help of semi-structured proforma. The data was analysed by descriptive analysis using SPSS software. Results: Out of 199 patients, 109 had moderately differentiated squamous cell carcinoma, 51 poorly differentiated and 35 well differentiated. Adenocarcinomas numbered only four. 121 cases were in the age group of 40-59 years, 59 in 60-80 years and 19 in 20-39 years. All four cases of adenocarcinoma were seen between 40-59 years. 95 (47.7%) cases were in women who had 4 or more children, 120 presented with white discharge, 89 with bleeding per vagina and 68 had constitutional symptoms. Most of the patients with adenocarcinoma presented with bleeding per vagina. 151 was in stage IIIB, 29 in stage IIB, 14 in stage IVA and 5 in stage IB. Conclusions: Screening of cervical cancer should be emphasised in women with white discharge especially in rural areas for early detection of dysplastic cells and reduce mortality and morbidity in productive age. In addition health education has to be given to women regarding the awareness of hygiene, risk factors and symptoms of cervical cancer.

Background: Testicular germ cell tumors (TGCTs) are a relatively common malignancy in young men. The aim of this study was to investigate the clinicopathological features and survival of young Turkish patients with TGCT. Materials and Methods: In this retrospective study, the clinical and pathological characteristics of young Turkish patients with TGCT who were monitored by the Department of Medical Oncology of a military hospital between 2008 and 2013 were investigated. Overall survival data were analyzed. Results: Ninety-six patients were included in the study. The mean age was 26.4 years. Among the patients, 17.7% had seminoma and 43.8% had mixed non-seminomatous germ cell tumors. Some 46.9% were Stage I, 30.2% were Stage II, and 22.9 were Stage III. Of the patients, 83.3% received chemotherapy, 25% underwent retroperitoneal lymph node dissection (RPLND), 3.1% received radiotherapy, and 12.5% were followed-up without treatment. In addition, 18.8% of the patients were administered salvage chemotherapy due to relapse or progression. The 5-year overall survival rate was 90.2% for all patients. The 2-year overall survival rate was 100% for Stage I patients, 94% for Stage II patients, and 70.2% for Stage III patients. The difference between the survival curves of stages was statistically significant (p=0.029). Conclusions: In young Turkish patients with TGCT, good results were obtained with appropriate treatment, most receiving chemotherapy. The prognosis of the disease was good even in the advanced stage.

Objective : Malignant gliomas with neuronal marker expression (MGwNM) are rare and poorly characterized. Increasingly diverse types of MGwNM have been described and these reported cases underscore the dilemmas in the classification and diagnosis of those tumors. The aim of this study is to provide additional insights into MGwNM and present the clinicopathological features of 18 patients. Methods : We reviewed the medical records of 18 patients diagnosed as MGwNM at our institute between January 2006 and December 2012. Macroscopic total resection was performed in 11 patients (61%). We evaluated the methylation status of $O^6$-methylguanine-DNA methyltransferase (MGMT) and expression of isocitrate dehydrogenase 1 (IDH-1) in all cases, and deletions of 1p and 19q in available cases. Results : The estimated median overall survival was 21.2 months. The median progression-free survival was 6.3 months. Six patients (33%) had MGMT methylation but IDH1 mutation was found in only one patient (6%). Gene analysis for 1p19q performed in nine patients revealed no deletion in six, 19q deletion only in two, and 1p deletion only in one. The extent of resection was significantly correlated with progression free survival on both univariate analysis and multivariate analysis (p=0.002 and p=0.013, respectively). Conclusion : In this study, the overall survival of MGwNM was not superior to glioblastoma. The extent of resection has a significant prognostic impact on progression-free survival. Further studies of the prognostic factors related to chemo-radio therapy, similar to studies with glioblastoma, are mandatory to improve survival.

Background: Tumor recurrence is the most common cause of treatment failure, even after complete resection of early-stage non-small cell lung cancer (NSCLC). In this study, we investigated the prognosis of patients with early recurrence in order to identify independent risk factors related to early recurrence. Methods: Between February 1995 and December 2012, 242 patients who underwent surgical resection for stage I NSCLC at Dong-A University Hospital were reviewed. The factors predicting overall survival (OS) and early recurrence were investigated. We also investigated the relationship between the patterns and period of recurrence and clinicopathological factors. Results: For patients with stage IA and IB NSCLC, the 5-year OS rate was 75.7% and 57.3% (p=0.006), respectively. A multivariate Cox proportional hazards model demonstrated that gender (p=0.004), comorbidity number (p=0.038), resection type (p=0.002), and tumor size (p=0.022) were the statistically significant predictors of OS. Moreover, the multivariate analysis revealed that smoking history (p=0.023) and histologic grade (p=0.012) were the independent predictors of early recurrence. Additionally, only histologic grade (poor differentiation) was found to be significantly associated with a higher frequency of distant metastasis; there was no relationship between the patterns and period of recurrence and clinicopathological factors. Conclusion: The present study demonstrated that smoking history and histologic grade were independent prognostic factors for early recurrence within two years in patients with early-stage NSCLC. Patients with these predictive factors may be good candidates for adjuvant therapy.

This study examined the effects of the daily noise stress on body weight, feed intake and clinicopathological findings in Korean indigenous goats. A total of 14 male goats was divided into 2 groups (test and control) with same number (n=7), and exam was started 2 weeks later. This study composed 2 stages. First was noise stage i.e., noise (80-100 dB) inflicted on the test for 70 minutes each time (5 times/day), and have continued for 2 months. Second was no noise for 2 months. Body weight and daily gain in stress group was decreased compared with control group after imposing noise (first stage). However, these results were reversed after ceasing noise (second stage). Average daily feed intake was not significant different between two groups throughout the experimental periods. But, feed conversion ratio was lowerin control group than another. Clinicopathological findings including total protein, albumin, globulin, total bilirubin, total cholesterol, triglyceride, aspartate aminotransferase (AST), alanine aminotransferase (ALT), glucose, amylase, blood urea nitrogen (BUN), cortisol, total leucocytes and hemoglobin value showed no significant different between stress and control group.

Introduction: Human adiponectin (ApN) is a 30 kDa glycoprotein of 244-amino acids which is extensively produced by adipocytes. ApN acts via two receptors, namely adiponectin receptor-1 (Adipo-R1) and adiponectin receptor-2 (Adipo-R2). Studies have shown the presence of Adipo-R1 and Adipo-R2 expression immunohistochemically in human colorectal cancers (CRCs). However, only a few studies exist which investigated effects of adiponectin receptor expression on CRC characteristics. Objectives: In the present study, we aimed to explore Adipo-R1/-R2 expression in human colorectal cancers and any association with clinicopathological characteristics and survival. Materials and Methods: The study enrolled 58 colorectal cancer patients with tumor resection and a control group of 30 subjects with normal colon mucosa. Results: Positivity for Adipo-R1/-R2 expression was significantly more common in the control group in comparison to the patient group (both p<0.001). There was no significant association between Adipo-R1/-R2 expression and clinicopathological characteristics including age, sex tumor location, pTNM stage, Duke's stage, metastasis, histological differentiation, perineural invasion, venous invasion sex, lymphatic invasion, cancer-related mortality, tumor size and recurrence. Adipo- R1/-R2 positivity was also not significantly linked to progression-free or overall survival [p values (0.871, 0.758) and (0.274, 0.232), respectively]. Conclusions: Although significantly reduced Adipo-R1/-R2 expression was found in colorectal cancer patients, it had no influence on survival.

Background: The study aimed to evaluate the incidence of CpG island promoter methylation of BMP6, a member of the transforming growth factor beta family, in tissue samples from colorectal cancers (CRC) and look for its association with BMP6 expression and clinicopathological correlation. Materials and Methods: Methylation specific PCR for the BMP6 promoter region was performed with 85 frozen tissue samples of CRC and 45 of normal colon. Methylation status of MLH1 was also determined by the same method. Expression of BMP6 was evaluated by immunohistochemistry (IHC), using Allred's scoring system. The methylation status was analyzed against clinical and pathological parameters in CRC. Results: The study revealed BMP6 hypermethylation in 34 of 85 tumor specimens (40%), and 15 out of 45 normal tissue samples from CRC (33%). The incidence of hypermethylation was inversely correlated with IHC score. Allred's scores of 7 or more were correlated with lower frequency of BMP6 hypermethylation (29% compared to 50% in the remaining, p-value 0.049). However, there was no association between hypermethylation status and any clinicopathological parameters. The methylation status of BMP6 was not correlated with that of MLH1, a key methylation determinant in CRC. On survival analysis, there was no significant difference in progress-free survival (PFS) between the cases with and without hypermethylation (2-year PFS 74% and 76%, respectively). Conclusions: CpG island methylation of BMP6 is found in high frequency in CRC and this epigenetic event is associated with suppressed protein expression in the tumor tissue. However, the marker is not associated with tumor progression of the disease.

Purpose: The long-term survival rate of gastric cancer patients after surgery has recently increased as a result of making an early diagnosis of gastric cancer. Therefore, the incidence of remnant gastric cancer is increasing. This study was performed to evaluate the clinicopathological characteristics and prognosis of patients with remnant gastric cancer. Materials and Methods: From January 2005 to December 2009, twenty-nine patients with remnant gastric cancer and who underwent surgery at Pusan National University Hospital were enrolled in this study. We retrospectively reviewed and analyzed their medical records. We also divided them into two groups: the remnant gastric cancer (RGC)-B group (first operation for benign disease) and the RGC-M group (first operation for malignant disease). Results: The RGC-B group included ten patients and the RGC-M group included nineteen patients. The mean interval between the first and second operations was 17 years. The curative resection rate was 93.1% (27/29). The postoperative complication rate was 20.7% (6/29) and there was no perioperative mortality. Ten (37%) of twenty-seven patients experienced recurrence after curative resection and eight patients (27.6%) expired due to aggravation of remnant stomach cancer. An advanced TNM stage and non-curative resection were the negative prognostic factors for survival for patients with remnant stomach cancer (P=0.0453 and P<0.001). The RGC-M group showed a shorter interval (P<0.001) and the RGC-B group had more advanced TNM stage (P=0.003). Conclusions: Long-term follow-up should be considered not only for patients who undergo an operation for malignant disease, but also for the patients who underwent an operation for benign disease. When remnant gastric cancer is diagnosed, curative resection is essential to improve the survival.

The purpose of this study was to investigate the nutritional status before and after gastrectomy of gastric cancer patients in Jeonbuk Province. The subjects were 136 patients with gastrectomy of gastric cancer. We assessed the nutritional status before and after an operation by general characteristics (age, clinicopathological stage, type of operation, method of reconstruction), anthropometric characteristics (height, weight, skeletal muscle mass, body fat mass, body mass index (BMI), percent body fat, arm muscle circumference AMC, arm circumference AC) and biochemical characteristics (hemoglobin Hb, hematocrit Hct, mein corpuscular volume MCV, mean corpuscular hemoglobin MCH, total lymphocyte count TLC, serum albumin, serum transferrin). Mean ages were 60.0 yrs in males and 58.8 yrs in females. Age, clinicopathological stage, types of operation and reconstruction methods were not significantly different between males and females. Weight, skeletal muscle mass, body fat mass, BMI, percent body fat, AMC and AC significantly deteriorated by gastrectomy. There were severe weight losses in males and females after gastrectomy. Hemoglobin, Hct, MCV, MCH, TLC, albumin and transferrin significantly deteriorated by gastrectomy. After gastrectomy, subjects who were assessed as malnounrished in Hb and Hct were increased in male and those who were assessed as malnounrished in Hb were increased in females. These results suggest that a nutrition intervention, specially for energy, protein and iron, is necessary to improve the nutritional status of gastric cancer patients with gastrectomy.

Purpose: The epidermal growth factor receptor (EGFR) family plays a crucial role in the growth of malignant tumors. EGFR and human EGFR 2 (HER2) protein overexpression are associated with an unfavorable prognosis and are important therapeutic targets in breast cancer. The aim of this study was to evaluate the relationship between EGFR and HER2 expression and clinicopathological factors in papillary thyroid carcinoma (PTC) at a single institution. Methods: A total of 129 consecutive patients with PTC were enrolled in this study and underwent thyroid surgery between October 2013 and February 2015. EGFR and HER2 protein expression was evaluated in the 129 primary tumors by immunohistochemistry, and the results were compared with the clinicopathological features. Results: Of the 129 PTC tumors, 20 (15.5%) were HER2 positive, and 109 (84.5%) were HER2 negative. Moreover, EGFR positivity were observed in 111 (86%) tumors. The mean age of the patients was $46.3{\pm}11.9years$ (range, 20-74 years), and the mean tumor size was $1.08{\pm}0.75cm$ (range, 0.2-3.5 cm). Tumor size, extrathyroidal extension, histological subtype, and TNM stage were not significantly associated with EGFR or HER2 expression. Meanwhile, high Ki-67 labeling index was significantly associated with EGFR expression (P=0.002), HER2 expression was significantly associated with younger age (${\leq}45years$) and cervical lymph node metastasis. Conclusion: Based on our data, it is not clear whether EGFR and HER2 expression is associated with tumor aggressiveness in PTC.
