Objective: To assess the relation between XRCC3 Thr241Met polymorphism and lung cancer susceptibility of populations in East Asia.

Methods: Related studies of XRCC3 Thr241Met polymorphism and lung cancer susceptibility of populations in East Asia were collected through searching the Pubmed, Embase Library, SPRINGER, CNKI and CSSCI.

Results: According to the entry criteria, there were 8 case-control studies in the assessing system and there were 6 321 study cases, including 3 215 patients with lung cancer and 3 106 cases without cancers. Meta analysis results showed the combined OR value of the ratio of genotype Thr/Met+Met/Met and Thr/Thr was 1.03 (95%CI: 0.89-1.20) (P>0.05).

Conclusions: XRCC3 Thr241Met polymorphism may not related to lung cancer susceptibility of populations in East Asia. Allele 241Met did not increase the risk of lung cancer.

Human papillomavirus DNA and P16(INK4A) expression in concurrent esophageal and gastric cardia cancers.

World J Gastroenterol 2010 Dec;16(46):5901-6

Henan Key Laboratory for Esophageal Cancer Research, Department of Gastroenterology, The First Affiliated Hospital, College of Basic Medicine, Zhengzhou University, Zhengzhou 450052, Henan Province, China.

Aim: To investigate the relationship between human papillomavirus (HPV) infection and concurrent esophagus and gastric cardia cancer from the same patient (CC) and examine the significance of P16(INK4A) protein expression.

Methods: Polymerase chain reaction was used to detect the presence of HPV type16 (HPV16). The expression of P16(INK4A) protein was detected using immunohistochemistry.

Results: Among the CC specimens, HPV16-DNA was found in eight cases of esophageal squamous cell carcinoma (ESCC) and five cases of gastric cardia adenocarcinoma (GCA), respectively (47% vs 29%), and two of both ESCC and GCA. P16(INK4A) was highly expressed in both ESCC and GCA. In the HPV-associated positive CC, higher P16(INK4A) expression was observed in the GCA than in the ESCC (75% vs 25%, P < 0.05).

Conclusion: HPV16 as a correlated risk factor may play an important role in the development of ESCC and GCA. P16(INK4A) may be a screening index in the HPV-associated carcinoma of gastric cardia.

Genome-wide association study of esophageal squamous cell carcinoma in Chinese subjects identifies susceptibility loci at PLCE1 and C20orf54.

Nat Genet 2010 Sep 22;42(9):759-63. Epub 2010 Aug 22.

Cancer Research Center, Xinxiang Medical University, Xinxiang, Henan, China.

We performed a genome-wide association study of esophageal squamous cell carcinoma (ESCC) by genotyping 1,077 individuals with ESCC and 1,733 control subjects of Chinese Han descent. We selected 18 promising SNPs for replication in an additional 7,673 cases of ESCC and 11,013 control subjects of Chinese Han descent and 303 cases of ESCC and 537 control subjects of Chinese Uygur-Kazakh descent. We identified two previously unknown susceptibility loci for ESCC: PLCE1 at 10q23 (P(Han combined for ESCC) = 7.46 x 10(-56), odds ratio (OR) = 1.43; P(Uygur-Kazakh for ESCC) = 5.70 x 10(-4), OR = 1.53) and C20orf54 at 20p13 (P(Han combined for ESCC) = 1.21 x 10(-11), OR = 0.86; P(Uygur-Kazakh for ESCC) = 7.88 x 10(-3), OR = 0.66). We also confirmed association in 2,766 cases of gastric cardia adenocarcinoma cases and the same 11,013 control subjects (PLCE1, P(Han for GCA) = 1.74 x 10(-39), OR = 1.55 and C20orf54, P(Han for GCA) = 3.02 x 10(-3), OR = 0.91). PLCE1 and C20orf54 have important biological implications for both ESCC and GCA. PLCE1 might regulate cell growth, differentiation, apoptosis and angiogenesis. C20orf54 is responsible for transporting riboflavin, and deficiency of riboflavin has been documented as a risk factor for ESCC and GCA.
