  1. Down staging of cervical cancer In India“Your cooperation is needed” Dr. Sharda Jain Director: Global Institute of Gynaecoloy at Pushpanjali Crosslay Hospital Secretary general: Delhi Gynaecologist Forum

  2. Advanced Carcinoma Early Carcinoma

  3. Global Burden of Cervical Cancer • Worldwide, • 500,000women diagnosed per year1 • 270,000deaths per year1 • >1 million new casesof cervical cancer each year, 20502 One Death every 2 minutes

  4. Cancer Cervix World - No. - 2 New - 5 Lack Deaths - 2.75 India Number One New – 1.32 lack Deaths - o.74 lack One death every 7th minutes in India

  5. Cancer CervixLife Time Risk India = 20 – 35 / lack (35 – 64 yrs) Developed countries = 1-8/ lack It is expected by 2050 = double If no action is taken

  6. PATH (prog. Of appro. tech in Health) Most effective program of down staging of cervical Cancer is paps smear screening

  7. MASS PAPS SMEAR SCREENING {IARC - Int. agency of research on cancer } 35 – 64 yrs =93% reduction if Screening1-3 years = 84 % Reduction 5 years = 64% reduction 10years India No Govt. Effort for public Screening (non availability of Tech/ doctors to read paps smear )

  8. Alternative methodsfor down staging of the cervical cancer • VISUAL INSPECTION OF CERVIX WITH ACETIC ACID. (VIA) • Use of MAGNASCOPE instead of colposcope • SINGLE VISIT APPROACH i.e.Treatment with cryosurgery for VIA +ve women 4. SELF COLLECTED SAMPLE for cytology or HPV – DNA testing

  9. Alternative methodsfor down staging of the cervical cancer 5. Education and counseling 6. Increase coverage by camp approach 7. Low cost HPV test 8. HPV Vaccines.

  10. VIA AFTER APPLYING 3 % ACETIC ACID TO CERVIX “WHITE PATCHES” APPEARS DUE TO COAGULATION OF CELLULAR PROTEINS AND INDICATE THE ABNORMAL EPITHELIUM WHICH IS THICK AND DOES NOT ALLOW THE LIGHT REACTION TO PASS THROUGH. CERVICAL BIOPSIES - LSIL/HSIL

  11. Women were examined visually by simple speculum and colposcopically after application of 3 % acetic acid to cervix. Equal detection rates of cervical abnormalities by both techniques. Ottaviano and la torre 1982,

  12. VILI WHEN LUGOL’S IODINE IS APPLIED TO THE CERVIX, THE NORMAL CELLS CONTAINING GLYCOGEN STAIN DARK BROWN. THE ABNORMAL CELLS ARE RAPIDLY DIVIDING AND ARE DEFICIENT IN GLYCOGEN HENCE, REMAIN UNSTAINED WHICH ARE FURTHER EVALUATED BY COLPOSCOPY & BIOPSY.

  13. IARC studies in India and Africa • proved that VIA performed by trained paramedics has sensitivity of 64 to 90% and specificity of 73 to 91% which is comparable to conventional cytology. • specificity of VIA was increased by adding adjunctive test like VILI. • Advantages of visual technique are immediate results, making cost effective and has more than 99% negative predictive value. muwonge R (2007)

  14. Sensitivity and specificity are often used to summarise the performance of a diagnostic test. Sensitivity is the probability of testing positive if the disease is truly present. Specificity is the probability of testing negative if the disease is truly absent.

  15. Who Needs colposcopy ± Biopsy Ten to fifteen percent VIA+ve women require referral for colposcopy & colposcopic guided biopsies.

  16. LSIL / LGSIL Conservative treatment and follow up subsequently 6 monthly .

  17. HSIL / Cancer Specialized Treatment

  18. What Is Single Visit approach? In single visit approach cryo therapy is offered to all those women who are VIA +ve and cannot visit more than once for treatment.

  19. Tamil Nadu Study Single Visit approach - follow up after 7 years showed • 25% reduction in cervical cancer incidence • 35% reduction in cervical cancer mortality • 27.5% reduction in the incidence of stage II or advanced cancer compared to control group.

  20. What should be Indian Govt. Approach Cervical cancer Should be taken seriously for ↓ number & reduction in mortality . • Camp approach • Single visit approach Both can help to down stage the disease in resource poor settings like India. Self sampling in rural areas/ slums Pap Smear/ HPV

  21. HPVInfection

  22. 100% of cervical cancers are caused by HPV

  23. 93.5% of all cancer caused by HPV is Cervical Cancer

  24. Human Papillomavirus (HPV) 100 HPV Types Have Been Identified1 30 HPV Types are Transmitted by Genital skin to skin Contact 15 HPV Types are Oncogenic In India over 90% of Cervical Cancers are Caused by 5 HPV Types: HPV 16, 18, 45, 31 and 332

  25. In India, HPV 16, 18, 31, 33 & 45account for >92% Squamous Cell Carcinoma >95% Cervical Adenocarcinoma

  26. Adenocarcinoma is difficult to detect • Adenocarcinoma is difficult to detect with routine screening methods1 • The cervical smear brush cannot access the endocervical canal as easily as the outer surface of the cervix1 Adenocarcinoma:may be inaccessible to the cervical smear brush Cervical smear brush Cervix Squamous cell carcinoma: usually accessible to the cervical smear brush

  27. Adenocarcinoma of the cervix- An Emerging concern • Incidence increasing (20–25% of all cervical cancers), not prevented with traditional pap screening • More aggressive and occurs in younger women • > 90% of adenocarcinomas result from HPV 16, 18, 45, 33 and 311 • HPV 18 confers the highest risk

  28. Every woman is at risk of Cervical Cancer HPV infections are very common The risk starts from sexual debut1 and continues throughout life2

  29. Up to 80% of women will acquire an HPV infection in their lifetime5–7 HPV infections continue to occur in women over 25 years of age

  30. Progression of Cervical Disease Progression* Years Months Time Normal epithelium Invasive carcinoma HPV infection koilocytosis CIN2 CIN1 CIN3 Low-grade squamous intraepithelial lesion (ASCUS/LSIL) High-grade squamous intraepithelial lesion (HSIL) Regression

  31. The need for Vaccination against Cervical Cancer

  32. Virus-like particles (VLPs) as HPV vaccine antigens mimic the virus structure ‘Empty’ non-infectious virus-like particle (VLP) mimics the virus HPV-containing double stranded DNA Stanley M, et al. Vaccine 2006; 24(suppl 3):S3/106–113.

  33. Why vaccination is needed ?? • No protection through natural infection as HPV evades the immune system • Vaccines are highly immunogenic • Higher the serum antibodies, more is local neutralising antibody & longer the protection

  34. HPV types and cervical cancer HPV 33 HPV 16 HPV 18 HPV 45 HPV 31 Five most frequent and aggressive HPV types that cause cervical cancer worldwide + + + + These 5 HPV types are responsible for up to 92%of Cervical Cancer in India2 1. Bosch FX et al. Vaccine 2008; 26S: K1–16. 2. Bhatla N et al. Vaccine 2008; 26(23):2811-2817.

  35. 2 Vaccines • Gardasil • Cerverix

  36. Cervarix™ efficacy: Summary * The total vaccinated naive cohort (TVC-naive) included women who were given at least one vaccine dose, were evaluable for efficacy, and at baseline had normal cytology, were DNA negative for all 14 oncogenic HPV types investigated, and were seronegative for HPV-16 and HPV-18 (n=11641). ** Median follow-up of 39.5 months (post dose1) ***CIN2+ was defined histologically as CIN2, CIN3, adenocarcinoma in situ, or invasive carcinoma • References: • Paavonen J et al. Final Phase III Efficacy Analysis Of Cervarix™ In Young WomenAbstract presented at the 25th International Papillomavirus conference, Malmo, Sweden, 8-14 May 2009 • Skinner R et al. Cross-protective efficacy of Cervarix against oncogenic HPV types beyond HPV-16/18: final analysis of cross-protection-PATRICIA study. Abstract presented at the 25th International Papillomavirus conference, Malmo, Sweden, 8-14 May 2009

  37. HPV vaccines: Safety and approval • WHO’s Global Advisory Committee on Vaccine Safety (GACVS) concluded that the HPV vaccines had good safety profiles1 • U.S. Food and Drug Administration (FDA) approved both vaccines.

  38. Potential impact of HPV Vaccination HPV vaccination is the primary prevention strategy against cervical cancer HPV vaccination is predicted to have a major impact on the burden of cervical cancer, especially in settings without optimal screening programs

  39. FOGSI Recommendations Cervical cancer causes significant morbidity/ mortality HPV vaccine to be offered to all appropriate females who can afford the vaccine Vaccine should be given prior to sexual debut www.fogsi.org/hpv vaccine

  40. When is the best time to vaccinate? • Upto what age can the Vaccine be given

  41. FOGSI Recommendations – Vaccine Schedule Age for initiation of vaccination is 10- 12 years. Catch up vaccination is permitted up to 45 yrs Three doses at 0, 2 and 6 months with quadrivalent vaccine (Gardasil) Three doses 0, 1 and 6 months with bivalent vaccine (Cerverix) Intra muscular – Deltoid reason

  42. FOGSI RecommendationsNeed for Booster At present there is no data to support use of boosters www.fogsi.org/hpv vaccine

  43. Not recommended for use in pregnancy If patient becomes pregnant - Delay remaining doses till delivery If vaccinated during pregnancy - No intervention (MTP) needed Lactating women can receive the HPV vaccine and still continue breastfeeding as it is a vaccine without live viral DNA FOGSI Recommendations:Pregnancy & Lactation www.fogsi.org/hpv vaccine

  44. Do we need to Screen before Vaccination? No! The results of screening will not influence to decision to vaccinate because: Sexually active women continue to be at risk of new infections Hence, vaccination will protect women from future infections regardless of an on going infection NOTE: Vaccination will have NO effect on the on-going infection or lesion.
