48% cancers due to tobacco chewing

CHANDIGARH: On the occasion of National Cancer Awareness Day on Monday, the department of radiotherapy, in collaboration with department of community medicine, PGIMER organized an awareness and early detection camp at Indira Colony, Manimajra.

Nearly 600 people visited the camp and exhibition & about 300 people were examined by the faculty of the hospital.

PGI receives nearly 6,000 new cancer cases every year and this figure is on a rise. Cancer pattern in India reveals the preponderance of tobacco related cancers because besides smoking, tobacco chewing is also an important risk factor. Almost 48% of cancers are related to tobacco in India.

Tobacco firms kept radioactive link secret

TOBACCO companies knew for decades that cigarette smoke was radioactive and potentially carcinogenic but kept the information from the public, a new study says.
The industry began investigations into the possible effects of these radioactive particles, identified as polonium-210, on smokers as early as the 1960s, says a study by University of California at Los Angeles (UCLA) researchers, who analysed dozens of previously unexamined industry documents.

Smokers Quit With Cheap Remedy Used in Bulgaria for 40 Years

Interesting study..

Smokers Quit With Cheap Remedy Used in Bulgaria for 40 Years
2011-09-28 21:00:00.1 GMT


By Marthe Fourcade
    Sept. 29 (Bloomberg) -- For as little as $6, there may be a
smoking-cessation remedy that actually works.
    A clinical test of Tabex, sold in Eastern Europe for more
than four decades, shows that the plant-based medicine can
triple smokers’ chances of quitting compared with a dummy pill.
The results of a study on 740 people were published today in the
New England Journal of Medicine.
    The tablet, developed and sold by Bulgaria’s Sopharma AD,
may help smokers with limited means quit, scientists said. Most
of the 6 million people who die from tobacco use each year are
from low- and middle-income countries, according to the World
Health Organization.
    “The benefits of Tabex are comparable with those of other
smoking-cessation treatments, but at a fraction of the cost,”
Robert West of University College London’s Department of
Epidemiology and Public Health, who led the research team, said
in a statement.
    “Stopping smoking can be extremely difficult,” West said,
and the study’s results suggest Tabex could become “a practical
option even for the poorest smokers.”
    In India, where 20 cigarettes cost about $1.10, a course of
nicotine-replacement therapy costs about $150 and smoking-
cessation drugs as much as $200, West and his colleagues wrote.
    In the study, 8.4 percent of patients taking Tabex for 25
days with “minimal” counseling abstained from smoking for a
year, compared with 2.4 percent of those given a placebo. The
smokers who took the plant-based remedy reported more
gastrointestinal upset, the research shows.

                        Yellow Flowers

    Tabex tablets contain cytisine, a substance found in the
seeds of a tree called laburnum that produces yellow pea-
flowers, which mimics the effect of nicotine.
    Pfizer Inc.’s Chantix, a smoking-cessation drug available
in the U.S. and Europe on prescription, is also derived from
cytisine. One week’s worth of tablets for a patient taking three
a day costs about $63 on the website drugstore.com.
    The absolute difference in rates of tobacco abstinence
between the two patient groups in the Tabex study was lower than
for Chantix and similar to what has been found for nicotine-
replacement therapy, the scientists wrote. University College
London’s Cancer Research U.K. Health Behaviour Research Centre
and the Cancer Center and Institute of Oncology in Warsaw
conducted the research.
    Extab Corp. has licensed global rights to Tabex and is
conducting clinical trials designed to meet the standards of
Western regulators, the Delaware-incorporated company said on
its website. Extab is run by Sopharma Chief Executive Officer
Ognian Donev; Rick Stewart, former CEO of Amarin Corp.; and
Anthony Clarke, a researcher with a focus on neurology,
psychiatry and pain management, with the goal of winning
regulatory approval for Tabex, according to the website.
    A course of Tabex, which was first sold in Bulgaria in
1964, costs about $15 in Poland and $6 in Russia, where it is
sold over the counter, the study’s authors wrote.

An alternative approach to study the changes in the cancer pattern of men in India (1988-2005).

Abstract

Background: Changes in cancer pattern are often studied with regard to rank of leading sites, variation in age adjusted rates of sites over the time or with the help of time trends. However, these methods do not quantify the changes in relation to overall changes that occurred in the total cancer cases over the period of time. An alternative approach is therefore necessary, particularly to identify emerging new cancers. Methods: The cancer incidence data of various sites for men, over the periods 1988-90 and 2003-05 in India, for five urban registries namely Bangalore, Bhopal, Chennai, Delhi and Mumbai, functioning under the network of National Cancer Registry Programme (ICMR), formed the sources of data for the present analysis. Changes in incidence cases by various cancer sites for men are assessed by calculating the differences in incidence cases over the two period of time. Based on the contribution of each site to total change, the ten most leading sites are identified separately for each registry. The relative changes in the sites with time are taken to identify the most emerging new cancer cases over the period of time. Results: The pooled cancer cases for men among five urban registries increased from 30042 cases in 1988-90 to 46946 cases in 2003-05 registering an increase of about 55.8%. The lowest percentage of increase is observed in the registry of Mumbai (25.6%) and the maximum in Bhopal (96.4%). Based on the pooled figures of five urban registries, the lung cancer contributed the maximum % change (9.7%), followed by cancer of prostate (9.2%), mouth (7.5%), tongue (5.9%) and NHL (5.9%). Based on the pooled figures and the relative changes, the emerging new cancers are prostate (140%), liver (112%) and mouth (95%). The % change by sites and the emerging new cancers varied between the registries.

Are oral and dental diseases linked to cancer?

Abstract

Oral Diseases (2011) doi: 10.1111/j.1601-0825.2011.01837.x Objective:  Infection and inflammation play a role in carcinogenesis, and highly prevalent oral and dental diseases have been significantly linked to some types of cancer. This article reviews current literature in this area. Materials and Methods:  Open literature review using the PubMed database and focused on publications from 2000 to 2010. Results:  Numerous potential mechanisms are implicated in the oral disease/carcinogenesis paradigm, including infection- and inflammation-associated cell pathology and microbial carcinogen metabolism. Poor oral hygiene is associated with oral cancer, but there is also evidence of a possible link between oral or dental infections and malignancies in general. Conclusion:  Oral infections may trigger malignant transformation in tissues of the mouth and other organs. However, scientific evidence to date remains weak and further well-conducted studies are warranted before cancer can be properly added to the list of oral infection-related systemic diseases.

Nicotine dependence phenotype, time to first cigarette, and risk of head and neck cancer.

Abstract

BACKGROUND:

A behavioral phenotype that characterizes nicotine dependence, the time to first cigarette after waking, is hypothesized to increase the risk of head and neck cancer.

METHODS:

A case-control study of histologically confirmed head and neck cancer was conducted that included 1055 cases and 795 controls with a history of cigarette smoking.

RESULTS:

The pack-years-adjusted odds ratio was 1.42 (95% confidence interval [95% CI], 1.02-1.99) for an interval of 31 minutes to 60 minutes to first cigarette after waking and 1.59 (95% CI, 1.19-2.11) for an interval of 1 minute to 30 minutes. The risk estimates were similar when smoking was modeled as total years, smoking status (current vs former), number of cigarettes smoked per day, years since quitting, and excess odds ratio. Findings were consistent for cancers of the floor of the mouth, palate, and pharynx.

CONCLUSIONS:

Time to first cigarette is an indicator of increased nicotine dependence, smoke uptake, and risk of head and neck cancer. This high-risk group of individuals would benefit from targeted smoking interventions. Cancer 2011;. © 2011 American Cancer Society.

Campaign awareness and oral cancer knowledge in UK resident adult Bangladeshi: a cross-sectional study.

Abstract

Background:This study reports awareness of the 'Open up to Mouth Cancer' campaign materials and oral cancer knowledge among two UK adult Bangladeshi communities, both at high risk for oral cancer.Methods:Differences in the outcomes of campaign awareness and knowledge of oral cancer risk factors and early signs were compared between campaign and comparison areas. Home-based interviews were conducted with representative samples from both areas by bilingual interviewers. Data collected included a modified 36-item Humphris Oral Cancer Knowledge Scale and socio-demographic information. The data were collected 4 weeks after the campaign completion and analysed using χ(2)-tests and binary logistic regressions.Results:The response rate was 77%. Both awareness of the campaign materials (29.99% (95% confidence interval (CI) 15.82, 46.99) vs 8.12% (95% CI 6.16, 10.62)) and the mean Humphris Oral Cancer Knowledge Scale scores (13.32 (95% CI 11.06, 15.57) vs 8.27 (95% CI 6.59, 9.94)) were higher in the campaign area. The campaign area sample was significantly more likely to be aware of the materials (odds ratio (OR)=6.03, 95% CI 3.00, 12.1).Conclusion:Superior awareness and oral cancer knowledge was identified in the community with access to the campaign materials. Further evaluation to identify long-term campaign impact is required.British Journal of Cancer advance online publication, 23 August 2011; doi:10.1038/bjc.2011.317 www.bjcancer.com.
