Teacher : Dr. Yasmeen Kazi
Cancer
• It may be regarded as a group of disease
  characterized by : (a) abnormal cell growth, (b)
  ability to invade adjacent tissue & even distant
  organs, and (c) eventual death of the affected
  patients if tumor progressed beyond a critical
  stage.
• At the beginning of the century, cancer was the
  sixth most common cause of death worldwide,
  but now it’s the 2nd leading cause.
• There are wide variations in distribution of
  cancers around the globe, eg. Stomach cancer
  in Japan, cervical cancer in Columbia, and
  cancers of oral cavity in SEARs.
Mortality due to cancer : Worldwide vs. India

          Cancer Site               Deaths
           Lung (1st )             1.4 million
            Stomach                 740,000
              Liver                 700,000
         Colorectal (3rd )          610,000

          Breast (2nd )             460,000


          Cancer Site          Deaths (/ 100,000)

              Liver                  13.49

           Lung (2nd )                6.49

            Oral (1st )               4.82
• India accounts 86% of the world's oral cancer cases
  18 cases/100,000 (IIPH, feb.2011).
Oral cancers
What is Oral cancer..?

 Cancer that starts in the mouth is oral
  cavity cancer
  – Includes lips
  – Inside lining of cheeks (buccal mucosa)
  – Gingiva (gums)
  – Floor of the mouth
  – Anterior 2/3rds of the tongue
  – Hard palate
Major Risk Factors for Oral Cancer
               are:


                     Tobacco use - 90%

                     Alcohol use - 75-80%

                     Age over 40

                     UV – exposure – 30%
                      association with lip
                      cancer.
Additional Risk Factors Linked To
 Oral Cancer Include:
 HPV – 20 – 30% association
 HSV
 Nutritional deficiencies (Vit.A)
 Oral lichen planus
 Immuno- Supression
 Syphilis
 Marijuana use
 Chronic irritation (ill-fitted dentures, broken
  tooth)
 Chronic candidiasis
 P53 gene mutation (under study)
Tobacco
• Approx. 90% of oral cancers in SEARs are
  linked to tobacco smoking or chewing.
• The risk of oral cancer increases with the :
  amount and duration both.
• Smokers have 6 times greater risk of
  developing oral cancer than nonsmokers.
• Tobacco users who regularly use alcohol are
  at greatest risk.
• All tobacco types are associated with oral
  cancer, for example: cigarettes / cigars / pipes
  / snuff / chew / quid.
• Indigenous forms of smoking are : bidi, chutta
  (epidermoid Ca of hard palate - Andhra
  Pradesh), chilam, hookah. It can also be
  inhaled as snuff.
• Most common form of tobacco chewing in India
  is betal quid : betal leaf, arecanut, lime &
  tobacco (36 times higher in non chewers).
• It is common for the poor people to rub with
  thumb – flakes of sun dried tobacco and slaked
  lime to form a mixture (khaini), which is then
  put in mouth at frequent intervals during the
  day.
• The areca nut
  contains three
  main alkaloids:
  Arecoline, Arecaidine
  and Guvacine which
  has vasoconstricting
  properties.
• The betel leaf
  chewed with it
  contains eugenol,
  also vasoconstrictor.
Symptoms

• The most common symptom is a sore in the
  mouth that bleeds easily and does not heal.
• Other symptoms include:
   – Pain in the mouth that does not go away
   – A lump or thickening in the cheek
   – A white or red patch on the gums, tongue,
     tonsil, or lining of the mouth
   – A sore throat or a feeling that something is
     caught in the throat
   – Difficulties in chewing, swallowing, or moving
     the tongue or jaw (late symptoms)
Oral cancer often precedes by a pre cancerous
stage (leuko/erythoplakia), which can be detected
upto 15 yrs .




• 5- 20 % of oral leukoplakia will turn malignant
• 10 -20% of submucous fibrosis will turn
  malignant
Relationship Between Cell Events
Prevention

Primary prevention : -
• Tobacco Control – if tobacco habits are
  eliminated from the community, a great deal of
  reduction in oral cancer incidence can be
  achieved.
       a) behavior modification
       b) counseling
       c) health education
       d) legislative measures

Tobacco Ban – Implications

• India 3rd largest producer of tobacco
• 900,000 employed in growing and curing
  industry and 3.4 million in manufacturing
• 97.7 million dollar trade surplus
• Smokeless tobacco $ 1 billion annually = 0.2 %
  of the gross national product

   “Only industry that has had a constant
     growth for last few decades”
Conclusion

• Banning tobacco- difficult but useful
• Behavioural modifications
  - do have an impact
  - however, time consuming
  - sustained effort required
• Nonetheless tobacco counseling must
  be pursued (national & individual)
Other methods of primary prevention


• Limiting Alcohol consumption
• Improve diet : fruits and vegetables
• Maintaining good oral hygiene
• Control of STDs
• Prompt treatment of conditions like Lichen
  planus, candidiasis.
• Correcting ill - fitted dentures and other
  conditions causing chronic irritation.
• Protection from excessive UV – exposure.
Secondary prevention
• Oral cancers are easily accessible for inspection
  allowing early detection.
• If detected early (pre – cancerous lesions), can be
  easily treated or cured.
• The pre – cancerous lesions can be detected upto 15
  years, prior to becoming invasive carcinoma.
• Regular annual oral cancer examinations after age
  40.
• The primary health care workers are in a strategic
  position to detect oral cancers at an early stage
  during home visits. They can prove to be a vital link &
  key instrument in control of oral cancer in countries
  like India.
• Leukoplakias can be cured by cessation of
  tobacco smoking.

• Radiation therapy and surgery are the main
  methods of treatment for oral cancer.

   Surgery : An operation to remove cancer cells.
   Radiotherapy : Uses high-energy rays to shrink
    or kill cancer cells.
• In advanced cancer, chemotherapy may
  be used in combination with either
  treatment.
  – Chemotherapy - Uses anticancer drugs
    that attack cancer cells and normal cells.
    The drugs are usually given by injection or
    by mouth.

   5-year localized survival rate is 82%
   5-year overall survival rate is 59%
NATIONAL CANCER CONTROL
          PROGRAMME:
• National Cancer Control Programme was
  started in 1975-76. Its Goals & Objectives
  are: -

1. Primary prevention of cancers by health
  education regarding hazards of tobacco
  consumption and necessity of genital
  hygiene for prevention of cervical cancer.
2. Secondary prevention by early detection and
  diagnosis of cancers, for example, cancer of
  cervix, breast cancer and the oro-pharyngeal
  cancer by screening methods and patients‘
  education on self examination methods.

3. Strengthening of existing cancer treatment
  facilities, which were inadequate.

4. Palliative care in terminal stage cancer.
Strategies

• Prevention and early detection of cancers
