Over half of the world's population is exposed to household air pollution from the burning of solid fuels at home. Household air pollution from solid fuel use is a leading risk factor for global disease and remains a major public health problem, especially in low- and mid-income countries. This is a particularly serious problem in China, where many people in rural areas still use coal for household heating and cooking. This review focuses on several decades of research carried out in Xuanwei County, Yunnan Province, where household coal use is a major source of household air pollution and where studies have linked household air pollution exposure to high rates of lung cancer. We conducted a series of case-control and cohort studies in Xuanwei to characterize the lung cancer risk in this population and the factors associated with it. We found lung cancer risk to vary substantially between different coal types, with a higher risk associated with smoky(i.e., bituminous) coal use compared to smokeless(i.e., anthracite) coal use. The installation of a chimney in homes resulted in a substantial reduction in lung cancer incidence and mortality. Overall, our research underscores the need among existing coal users to improve ventilation, use the least toxic fuel, and eventually move toward the use of cleaner fuels, such as gas and electricity.

Cholangiocarcinomas(CCAs)are rare tumors that originate from cholangiocytes in the bile ducts and are classified as intra-or extrahepatic(ICC or ECC).ICCs account for 10–12%of liver cancers,while ECCs account for approximately one-third of biliary tract cancers(1).Incidence rates of CCA are geographically variable,with the highest rates in ***,even in the highest incidence country(South Korea)the rates are only 2.8 and 2.2 per 100,000 person-years for ICC and ECC,respectively(2).Incidence rates of both ICC and ECC have been increasing in most countries globally,which potentially indicates a changing etiology(2).

Testicular cancer survival rates improved dramatically after cisplatin-based therapy was introduced in the 1970s. However, chemotherapy and radiation therapy are potentially carcinogenic. The purpose of this study was to estimate the risk of developing second primary cancers including the risk associated with primary histologic type （seminoma and non-seminoma） among testicular cancer survivors in Germany. We identified 16 990 and 1401 cases of testicular cancer in population-based cancer registries of East Germany （1961-1989 and 1996-2008） and Saarland （a federal state in West Germany; 1970-2008）, respectively. We estimated the risk of a second primary cancer using standardized incidence ratios （SIRs） with 95% confidence intervals （95% Cls）. To determine trends, we plotted model-based estimated annual SIRs. In East Germany, a total of 301 second primary cancers of any location were observed between 1961 and 1989 （SIR： 1.9; 95% Ch 1.7-2.1）, and 159 cancers （any location） were observed between 1996 and 2008 （SIR： 1.7; 95% Ch 1.4-2.0）. The SIRs for contralateral testicular cancer were increased in the registries with a range from 6.0 in Saarland to 13.9 in East Germany. The SIR for seminoma, in particular, was higher in East Germany compared to the other registries. We observed constant trends in the model-based SIRs for contralateral testicular cancers. The majority of reported SIRs of other cancer sites including histology-specific risks showed low precisions of estimated effects, likely due to small sample sizes. Testicular cancer patients are at increased risk especially for cancers of the contralateral testis and should receive intensive follow-ups.

AIM: To explore the association between methylation in leukocyte DNA and colorectal cancer (CRC) risk in male smokers using the α-tocopherol, β-carotene cancer prevention study. METHODS: About 221 incident CRC cases, and 219 controls, frequency-matched on age and smoking intensity were included. DNA methylation of 1505 CpG sites selected from 807 genes were evaluated using Illumina GoldenGate Methylation cancer Panel I in pre-diagnostic blood leukocytes of study subjects. Tertiles of methylation level classified according to the distribution in controls for each CpG site were used to analyze the association between methylation level and CRC risk with logistic regression. The time between blood draw to cancer diagnosis (classifying cases according to latency) was incorporated in further analyses using proportional odds regression. RESULTS: We found that methylation changes of 31 CpG sites were associated with CRC risk at P cancer susceptibility and some were related to tumor development over time. Further studies are warranted to confirm and refine our results.
