Prevention of Betel Quid Chewers’ Oral Cancer in the Asian-Pacific Area
263
269
EN
“Betel quid chewers’ oral cancer” is one of the most common malignancies in South and SoutheastAsian countries.Oral premalignancies are also very common in betel quid chewers and about 10% of these undergo malignanttransformation. Although education for cessation of the betel quid chewing habit is important, there are few adequatestrategies and policies for primary prevention, health promotion and education related to oral cancer control, especiallyin rural areas. In addition to oral health education, it is also crucial to establish a data-management system as wellas monitoring and evaluation systems for oral cancer prevention.

An Epidemiological Overview of Environmental and Genetic Risk Factors of Pancreatic Cancer
271
280
EN
This paper overviewed risk factors of pancreatic cancer. Both genetic and environmental factors may be playingsignificant roles in the development of pancreatic cancer. Cigarette smoking has been established as a major riskfactor for pancreatic cancer, based on findings from almost all epidemiological studies. Long-term smoking cessationmay reduce the risk. The evidence that alcohol drinking and coffee consumption increase the risk is not sufficient,although an association with higher level of consumption remains a possibility. Diabetes mellitus, long-standingdiabetes in particular, may be a risk factor for pancreatic cancer. Individuals with hereditary pancreatitis or nonhereditarychronic pancreatitis are possibly at increased risk of pancreatic cancer. Higher intake of meat and fatmay be associated with an increased risk, while consumption of fruits/vegetables appears to have a protective effect.Individuals with mutations or deletion in such genes as K-ras, p16, p53, DPC4, and BRCA2 increased the risk ofdeveloping pancreatic cancer. Cigarette smoking may play a role in the development of these mutations.

Distribution of Cancer Patients According to Time Taken From Starting Day of Symptoms to Reporting at a Regional Cancer Institute in Eastern India
281
286
EN
A retrospective study of the patients registered during 1997 aiming the time taken by the patients from theirstarting day of symptoms of cancer to reporting i.e. duration of symptoms at Chittaranjan National Cancer Institute(CNCI) a regional cancer institute in Eastern India. During 1997 a total of 3628 cancer patients registered at CNCI.Out of these, 716(19.74%) could not remember the duration of symptoms of their diseases at the time of first reporting.For this reason only the remaining 2912 cases were considered in the present study. Only 83(2.85%) reported withinone month of the initial onset of symptoms. The vast majority of patients, a toal of 2829 (97.15%), appeared athospital after several months, contributing to a moderate to advanced stage of their disease at first contact. Thiswould clearly be expected to lead to poor success in treatment. Late reporting by the patients is most probably dueto lack of awareness about the symptoms of cancer. The patients were from rural, semi-urban and urban populations.Measures of association showed significant links between the place of residence (p<0.55), age (p<0.001), sex (p<0.001),general health condition of the patients at first contact (p<0.052), the economic status (p<0.51) and the treatmentcompliance (p<0.26) with the duration of symptoms. Tumours of some primary sites like the cervix, breast (female),oral cavity, thyroid and penis, for which treatment responses are good to very good in early stages were also considered.For these primary sites, statistical measures showed late reporting by the patients which resulted in poor treatmentcompliance as well as a poor treatment response.

An Estimate of the Potential for Cancer Prevention in Japan
287
292
EN
Cancer prevention is an important strategy in cancer control and it consists of primary prevention and secondaryprevention. Major avoidable or manageable risk factors for cancer identified from previous studies are tobacco,diet and infection. Some cancer could be prevented by controlling those risk factors. In Japan screenings for gastriccancer, cervical cancer, lung cancer, breast cancer and colo-rectal cancer have been widely conducted under the Lawof Health Maintenance for the Aged. In planning and evaluating cancer control activities in Japan, it was considereduseful to estimate the potential of primary and secondary prevention of cancer. The author estimated the potentialof cancer prevention in Japan twice previously in 1990 and 1999. In this paper the potential of cancer prevention inJapan was re-estimated by using a different method and more recent data. From the present study it was estimatedthat about 25% of cancer occurrence could be prevented by control of smoking, diet and infection, about 9-15% ofcancer deaths could be prevented by cancer screening, and about 6- 10 % of cancer deaths could be prevented byapplication of the state-of-the art diagnosis and treatment of cancer, altogether about 40-50% of cancer occurrences/deaths could be prevented if all possible measures for cancer prevention are applied to the general public and cancerpatients in Japan.

An Assessment of Cancer Incidence Patterns in Parsi and Non Parsi Populations, Greater Mumbai
293
298
EN
The Mumbai Cancer Registry has been in operation since 1964 and reliable morbidity and mortality data on cancer havebeen obtained for the first time in India, from a precisely outlined population. An attempt has been made to examine thedifferences noticed in the site-specific cancer risk, between two groups of people living in this area-the Parsi and non Parsipopulation of Mumbai.For this study, data has been utilized, collected by Mumbai Cancer Registry for the latest five years. For comparisonbetween Parsi and non Parsi populations, crude and age-adjusted rates have been used.The overall age-adjusted rates for the Parsi’s were found to be lower than those for the non Parsi populations and morenoticeably their site-specific risks seem to differ radically from the non Parsi pattern. Cancers of the buccal cavity, pharynx,larynx, oesophagus and cervix uteri which are frequently seen in the non Parsi population, are less commonly observed inthe Parsi community. On the other hand the Parsi rates are higher at site such as the female breast, endometrium, lymphomasand leukaemias.The observed site-specific contrast are believed to be due to differences present in the habits, customs and economicstatus of the two groups.

EN
Hepatitis B virus (HBV), distributed throughout the world, is classified into seven geographically separatedgenotypes designated A to G. Since the prevalence of HBV infection in isolated ethnic Tibetan populations in China,and the HBV genotypes involved have been hither to remained unclear, we collected 262 blood samples from fourisolated villages in the east and west regions of Tibet. The prevalence of HBV infection was estimated by EIA forHBV Ag and HBV Ab. The HBV genotypes were determined by a PCR-microwell plate hybridization method usingplasma DNA. The prevalence of HBV Ag and HBV Ab positives was 19.1% (50/262 cases) and 29.0% (76/262 cases),respectively. We detected only the C genotype (20/20 cases), this being known as a predominant type of HBV amongMongoloid populations in Asia. The results revealed, for the first time, that Tibetan villagers have a high rate ofinfection with HBV of C genotype, in line with the available data for chronic hepatitis and liver cancer.

306
EN
Carcinoma of the uterine cervix is preceded by well characterized pre-cancerous lesions which if left untreatedmay progress to invasive carcinoma. In the present study women in the age group of 35-55 years with cervicalintraepithelial lesions (CIN I & II) were treated with vitamin E and advised to come for follow up after every threemonths for one year. This preliminary report shows vitamin E can restrict and regress CIN I & II lesions withelevation in circulating vitamin E levels. Improvement in immune status as reflected in mitogenic responses ofperipheral blood lymphocytes was also noted.

Estimate of the Incidence of Hepatocellular Carcinoma Among Carriers of HBsAg (+) in the General Population of Hanoi, Viet Nam from 1991-93
309
314
EN
<b>Background:</b> The estimated number of carriers of HBsAg (+) in the world significantly increased from 120 to 350million from the 1970s to the 1990s . Eighty per cent of liver cancers are estimated to be due to chronic HBV infection.However, only limited data are available regarding liver cancer rates among carriers of HBsAg (+). The aim of thepresent study was to estimate the incidence of liver cancer among carriers of HBsAg (+) in the general population ofHanoi City, Viet Nam.<br/><b>Method</b>: Data were derived from published reports for incidence of liver cancer (population-based cancer registry),the risk of HBV infection for liver cancer (case-control study), and the prevalence of HBV infection (stratified randomsampling of the general population) in the same population of Hanoi City. The Method of Indirect Estimation in aCase Control Study was used in this study.<br/><b>Results</b>: Crude incidence rates per 100,000 were 114 and 37 for carriers of HBsAg (+) in males and females,respectively. The age-standardized incidence rate per 100,000 among carriers of HBsAg (+) for liver cancer was 166in males and 58 in females, (ASR, world population). The annual incidence of liver cancer among carriers of HBsAg(+) was strongly correlated with increased age in both males and females: the estimated value sharply increasedfrom 6 to 655 per 100,000 for persons aged 0-9 and 50+, respectively, in males. Similarly, the estimated incidence ofliver cancer also sharply increased from 8 to 233 per 100,000 for the age groups 10-19 and 50+, respectively, infemales.<br/><b>Conclusion</b>: The present results indicate a high age-dependent incidence of liver cancer among carriers of HBsAg(+) in a general population. These results for Hanoi City, Viet Nam point to the magnitude of the problem andprovide a basis for intervention.

Valid Responses to ABO Blood Type Questions in a Self-reporting Questionnaire
315
317
EN
This paper reports the sensitivity and specificity of self-reported ABO blood type. Subjects were 283 outpatientswho participated in Helicobacter pylori eradication program at Aichi Cancer Center Hospital. Excluding sevenpatients, an ABO blood test was successfully conducted for 276 participants (133 males and 143 females). Only threeparticipants answered their blood type differently from the results of the blood test; one A-type male answered to bewith AB type, one B-type male with AB type, and one AB-type male with A type. Nine participants stated that theydid not know their ABO blood type. The sensitivity was 98.7% (95% confidence interval, 92.8-100.0%) for 75 Otypeindividuals, 96.1% (90.3-98.9%) for 102 A-type individuals, 92.9% (84.1-97.6%) for 70 B-type individuals, and93.1% (77.2-99.2%) for 29 AB-type individuals, when the nine individuals were included. The specificity was morethan 99% for any blood type. These findings revealed that self-reported ABO blood type is highly valid forepidemiologic studies.
