Background: Previous studies suggested that the H63D and C282Y polymorphisms in the HFE genes were susceptible to many cancer types, nevertheless, the present results were inconclusive. Thus, the present study was aimed to evaluate the association between the HFE polymorphisms (H63D and C282Y) and cancer risk via meta-analysis. Materials and Methods: We retrieved PubMed, Google Scholar, Embase and Web of Science databases for all eligible studies up to April 1, 2015. All the statistical analysis was conducted by STATA 12.0. Results: Finally, a total of 20 publications including 24 case-control studies, comprising 6,524 cases and 31,080 controls for HFE-C282Y polymorphism and 19 publications including 21 case control studies, comprising 5,648 cases and 14,257 controls for HFE-H63D polymorphism were enrolled in our analysis. An increased risk for overall cancer risk was identified in HFE-H63D polymorphism under allele contrast (D vs H: OR=1.153; 95%CI=1.031-1.289, Pheterogeneity=0.002), homozygotes vs wide type (DD vs HH: OR=1.449; 95%CI=1.182-1.777, Pheterogeneity=0.391), dominant model (DD+HD vs HH: OR=1.145; 95%CI=1.007-1.301, Pheterogeneity=0.002) and recessive model (DD vs HD+HH: OR=1.416 ; 95%CI=1.156-1.735, Pheterogeneity=0.549), as well as HFE-C282Y under homozygotes vs wide type (YY vs CC: OR=1.428, 95%CI=1.017-2.006, Pheterogeneity=0.220). In addition, in the stratified analysis by cancer type, an increased risk was identified in hepatocellular carcinoma and breast cancer in C282Y polymorphism, as well as pancreatic cancer in H63D polymorphism, whereas a decreased risk of colorectal cancer was identified in C282Y polymorphism. Conclusions: Present study suggested that H63D and C282Y polymorphisms associated with an increased risk of overall cancer. Nevertheless, well-designed study with large sample size will be continued on this issue of interest.

Purpose: This study aimed at summarizing epidemiological evidence of the association between gestational diabetes mellitus (GDM) and subsequent risk of cancer. Materials and Methods: We searched Medline, Embase, Cancer Lit and CINAHL for epidemiological studies published by February 1, 2014 examining the risk of cancer in patients with history of GDM using highly inclusive algorithms. Information about first author, year of publication, country of study, study design, cancer sites, sample sizes, attained age of subjects and methods used for determining GDM status were extracted by two researchers and Stata version 11.0 was used to perform the meta-analysis and estimate the pooled effects. Results: A total of 9 articles documented 5 cohort and 4 case-control studies containing 10,630 cancer cases and 14,608 women with a history of GDM were included in this review. Taken together, the pooled odds ratio (OR) between GDM and breast cancer risk was 1.01 (0.87-1.17); yet the same pooled ORs of case-control and cohort studies were 0.87 (0.71-1.06) and 1.25 (1.00-1.56) respectively. There are indications that GDM is strongly associated with higher risk of pancreatic cancer (HR=8.68) and hematologic malignancies (HR=4.53), but no relationships were detected between GDM and other types of cancer. Conclusions: Although GDM increases the risk of certain types of cancer, these results should be interpreted with caution becuase of some methodological flaws. The issue merits added investigation and coordinated efforts between researchers, antenatal clinics and cancer treatment and registration agencies to help attain better understanding.

Background: Malignant mesothelioma (MM) is an aggressive tumor of mesothelial surfaces. Previous studies have observed an association between ABO blood groups and risk of certain malignancies, including pancreatic and gastric cancer; however, no information on any association with MM risk is available. The aim of this study was to investigate possible associations amoong MM clinicopathological features and ABO blood groups and Rh factor. Materials and Methods: In 252 patients with MM, the ABO blood group and Rh factor were examined and compared with the control group of 3,022,883 healthy volunteer blood donors of Turkish Red Crescent between 2004 and 2011. The relationship of blood groups with various clinicopathological features were also evaluated in the patient group. Results: The median age was 55 (range: 27-86) and 61.5% of patients were male. While 82.8% of patients had a history of exposure to asbestos, 60.7% of patients had a smoking history. Epithelioid (65.1%) was the most common histology and 18.7% of patients had mixed histology. Overall, the ABO blood group distribution of the 252 patients with MM was comparable with the general population. The median overall survival (OS) was 14 months (95% confidence interval, 11.3-16.6 months). The median OS for A, B, AB, and O were 11, 15, 16, and 15 months respectively (p=0.396). First line chemotherapy was administered to 118 patients. The median OS of patients on pemetrexed or gemcitabine was longer than patient who was not administered chemotherapy [17 months (95%CI, 11.7-22.2) vs. 9 months (95%CI, 6.9-11.0); p<0.001]. Conclusions: The results of this study suggest that patients with MM can benefit from treatment with pemetrexed or gemcitabine in combination with cisplatin. We did not observe a statistically significant association between ABO blood group and risk of MM.

Background: Transcription factor FOXP3 characterizes the thymically derived regulatory T cells. FOXP3 is expressed by cancer cell itself and FOXP3 expression was induced by TGF-${\beta}$ treatment in pancreatic cancer cell line. However, the expression of FOXP3 expression is not well known in patients with lung cancer. This study was conducted to investigate the expression of FOXP3 in patients with lung cancer and to investigate the regulation of FOXP3 expression by the treatment of TGF-${\beta}$ and DNA methyltransferase inhibitor in lung cancer cell lines. Methods: FOXP3 expression in the tissue of patients with resected non-small cell lung cancer (NSCLC) was evaluated by immunohistochemistry. The regulation of FOXP3 expression was investigated by Western blot and RT-PCR after lung cancer cell lines were stimulated with TGF-${\beta}1$ and TGF-${\beta}2$. The regulation of FOXP3 expression was also investigated by RT-PCR and flow cytometry after lung cancer cell lines were treated with DNA methyltransferase inhibitor (5-AZA-dC). Results: FOXP3 expression was confirmed in 27% of patients with NSCLC. In NCI-H460 cell line, TGF-${\beta}2$ decreased FOXP3 mRNA and protein expressions. In A549 cell line, both TGF-${\beta}1$ and TGF-${\beta}2$ decreased FOXP3 mRNA and protein expressions. 5-AZA-dC increased FOXP3 mRNA expression in NCI-H460 and A549 cell lines. Moreover, 5-AZA-dC increased intracellular FOXP3 protein expression in A549 cell lines. Conclusion: It was shown that FOXP3 is expressed by cancer cell itself in patients with NSCLC. Treatment of TGF-${\beta}2$ and DNA methyltransferase inhibitor seems to be associated with the regulation of FOXP3 expression in lung cancer cell lines.

To determine whether bile juice exclusion can prevent the mucosal damage, and Insulin-like growth factor-I can promote mucosal regeneration in ischemia-reperfusion injury of the bowel, 39 weanling rats with 10 cm of Thiry-Vella loop were studied. Animal groups were; Control, BL(common bile duct ligation), IGF{insulin-like growth factor-I(IGF-I) infusion} and IGF-BL(combined treatment). IGF-I(1.5 mg/kg/day) was continuously delivered through a subcutaneously implanted miniosmotic pump. After 15 minutes of superior mesenteric artery clamping, a tissue specimen(P) was taken after 30 minutes of reperfusion. Intestinal continuity was restored to allow oral feeding. A specimen of main tract(M) and another of the Thiry-Vella loop(T) were collected for histomorphometry after 48 hours of reperfusion and free feeding. Villus size ratio(VSR), crypt depth(CD), crypt-depth/villus-height ratio(CVR) and injury score(IS) were measured in 15 consecutive villi. The postoperative mortalities of bile duct ligation groups(BL and IGF-BL) were higher than those of other groups. In control group, VSR of M was lower(P<0.05) than P or T, but not in the other groups. VSR of M in control was lower than those in other groups. CD of T in control, IGF and IGF-BL group were higher than those of M. CD of M and T showed gradual increments from control, IGF and IGF-BL group, respectively. CVR of M and T in IGF group were higher than those in control. CVR in IGF-BL group, T was higher than M, and M was higher than P. About IS, M of BL($20.1{\pm}2.5$) and IGF-BL($20.9{\pm}3.3$) groups were significantly lower than that of control($32.4{\pm}2.5$). These results suggest that the exclusion of bile juice reduces the severity of the reperfusion injury of the mucosa, by inability to activate pancreatic enzymes and IGF-I stimulates mucosal regeneration in injured bowel, and the effect is potentiated by bile juice exclusion.

To clarify the clinicopathologic features of small-cell carcinomas (SCC) of the stomach, we reviewed three cases of surgically treated SCC. The first case was a pure SCC, with severe pancreatic invasion and peritoneal seeding. A gastro-jejunostomy was performed. Postoperative chemotherapy was performed with CDDP and VP-16 (8 cycles) but showed disease progression (PD); a consecutive chemotherapy with CDDP and irinotencan (2 cycles) also showed PD. A third line with CDDP, VP16, ifosfamide, and mesna was followed by a 4th line (CDDP and Taxol). The male patient died with liver metastasis and peritoneal seeding 14 months after the operation. The second case was a SCC mixed with a poorly differentiated adenocarcinoma. Profound lymphadenopathy and liver metastasis were found. Two cycles of preoperative chemotherapy with TS-1 and CDDP were performed, which showed nearly complete remission for lymphadenopathy and partial response for the primary tumor site and liver metastatic lesion. A total gastrectomy and extended lymphadenectomy was performed. There were no viable cancer cells in 35 retrieved lymph nodes. Postoperative chemotherapy using the same regimen was performed for 4 cycles. Enlarged liver metastasis was found at the follow-up CT scan, so a posterior segmentectomy of liver was performed. After liver surgery, the chemotherapy regimen was changed to irinotecan and cisplatin. This male patient has been in good health for the f4 months since gastric surgery. The third case was a pure SCC, and a subtotal gastrectomy was performed curatively. That male patient received 5 cycles of TS-1 and is still in good health 14 months after operation.

Carbohydrate antigen 19-9 (CA 19-9) is a widely-used tumor marker in patients with pancreatic cancer. However, some patients with respiratory disease also exhibit elevated serum CA 19-9 levels. We report a case of normalization of elevated serum CA 19-9 levels after treatment of the nodular bronchiectatic form of Mycobacterium abscessus lung disease. A 40-year-old man visited our hospital because of chronic cough and sputum. A computed tomography scan revealed severe bronchiectasis in the right upper and right middle lobes. Nontuberculous mycobacteria were repeatedly isolated and identified as M. abscessus. The serum CA 19-9 level was elevated to 142.35 U/mL (normal range, <37 U/mL). Surgical resection was performed because of failure of sputum conversion after antibiotic treatment. The serum CA 19-9 level returned to the normal range after surgery. This case suggested that serum CA 19-9 levels could be elevated in patients with the nodular bronchiectatic form of M. abscessus lung disease.

Thirty piglets weaned at 24.5 d of age ($6.9{\pm}0.5kg$) randomly alloted to 3 treatments were used to investigate the effect of dietary tallow on average performance, digestibility of nutrients, metabolic utilization of energy and body composition at 25 kg. Weaned piglets respond to increasing levels of dietary tallow from 0 to 4% and 8% by digestive and metabolic adaptation. Apparent fecal digestibility of fat (AFDf) was highly correlated with the level of dietary tallow (X as % of fat extracted after HCl hydrolysis) by the following curvilinear equation of regression: $AFDf=33.8+6.9X-0.3X^2$. Feed intake expressed as DE was only significantly increased at the higher inclusion level of tallow. But neither average daily gain, nor feed conversion was affected by the addition of fat. On the other hand, body composition at 25 kg was equally affected, by both levels of supplementary fat; dry matter and energy content in the body were significantly higher (p<0.01) in piglets receiving tallow. As a consequence, the energy cost of the live weight gain was also increased from 23 to 24.7 MJ DE/kg (p<0.02) and the efficiency of energy deposition was decreased from 3.2 to 2.8 MJ DE/MJ deposited energy (p<0.01) in the presence of dietary tallow. An increase in the level of fat stimulated the activity of pancreatic lipase up to a constant value of $22{\pm}1.4IU/mg$ protein but conversely depressed the activity of amylase from 300 to 100 IU/mg of protein. The activity of liver acetyl CoA carboxylase and malic enzyme in the perirenal fat were low lind not affected by dietary fat; the activity of glucose-6-phosphate dehydrogenase was high. Opposite to that, the activity of acetyl CoA carboxylase and malic enzyme in the perirenal and backfat were higher than in the liver and both were significantly reduced by the inclusion of fat in the diet. A direct deposition of dietary fat has been demonstrated by increasing the energy and lipid content of the empty body weight gain between 7 and 25 kg of live weight, and decreasing the efficiency of digestible energy utilization.

Background: Previous studies have observed an association between ABO blood group and risk for certain gastrointestinal malignancies, including pancreatic and gastric cancer. However, it is unclear whether there is such an association with colorectal cancer (CRC). In this study, possible relationships between ABO blood groups and Rh factor and KRAS status in patients with CRC were investigated. Materials and Methods: In 1,620 patients with CRC, blood group and Rh factor were examined and compared with the control group of 3,022,883 healthy volunteer blood donors of the Turkish Red Crescent between 2004 and 2011. The relationship of blood groups with wild type K-ras status was also evaluated. Results: Overall distributions of ABO blood groups as well as Rh factor were comparable between patients (45% A, 7.2% AB, 16.4% B, 31.4% O, and 87.2% Rh+) and controls (42.2% A, 7.6% AB, 16.3% B, 33.9% O, and 87.7% Rh+) (p=0.099). However, there were statistically significant difference between patients and controls with respect to O vs. non O blood group (p=0.033) and marginally significant difference for A vs. non-A blood group (p=0.052). Among patients, the median age was 62 (range 17-97), 58.1% were male. There were no statistically significant differences respect to sex and K-ras status. Conclusion: In present study, the ABO/Rh blood groups were statistically significantly associated with the risk of CRC. There were no relationship between K-ras status and ABO blood group and Rh factor. However further studies with larger numbers of patients are needed to establish the role of blood groups and to define t he mechanisms by which ABO blood type affect CRC.
