THE NEW CERVICAL CANCER SCREENING PROGRAM The Renewal THE NEW CERVICAL CANCER SCREENING PROGRAM
CERVICAL CANCER 4th most common cancer in women worldwide
CERVICAL CANCER 4th most common cancer in women worldwide >250,000 deaths/year
CERVICAL CANCER 4th most common cancer in women worldwide >250,000 deaths/year 85% of cervical cancer incidence and mortality occurs in less developed countries
CERVICAL CANCER 4th most common cancer in women worldwide >250,000 deaths/year 85% of cervical cancer incidence and mortality occurs in less developed countries – limited or no screening
CERVICAL CANCER Incidence
CERVICAL CANCER Mortality
CERVICAL CANCER In our region Australia: Incidence - 5 per 100,000 women Mortality - 2 per 100,000 women Melanesia (PNG, Vanuatu, Fiji) : Incidence - 33 per 100,000 women (x7) Mortality - 20 per 100,000 women (x10)

THE IMPORTANCE OF SCREENING 80% of women with cervical cancer are either under- screened, or have never been screened
CERVICAL CANCER SCREENING in AUSTRALIA Current National Cervical Cancer Screening Program since 1991 Women aged 18-69 yrs 2 yearly Pap tests State/Territory based Registers
THE PAP TEST
CERVICAL CANCER SCREENING in AUSTRALIA Current Hugely successful – 50% reduction in cervical cancer incidence and mortality
SO WHY CHANGE??
Online petition shows women want to know more SO WHY CHANGE?? Online petition shows women want to know more The past week saw 70,000 people (so far) sign an online petition opposing the changes to the cervical screening program. The person behind the petition said she was motivated by “concern and worry”, because “[she] didn’t know about it and no one seemed to know about it”, and because “[she’d] love someone to be able to get down on our level and explain the testing”. Responses to her petition indicated widespread concern about safety of the new starting age and the wider screening interval. In addition, women perceived the renewed program as a cutback – that less screening is being driven by cost-savings rather than the availability of a better test.
SO WHY CHANGE?? 1. LIMITATIONS of CURRENT TESTING Reductions in cervical cancer incidence and mortality have plateaued over the last 10 years Current program has had no impact on certain groups – women < 25 years, subgroups of cancers (adenocarcinomas)
SO WHY CHANGE?? 2. INCREASED KNOWLEDGE The role of HPV in cervical lesions and cancer (causes >99% of cancer, most HPV infections will regress within 18 months) Pathogenesis of cervical cancer (most cancers take 10-15 years to develop)
HPV HPV causes >99% of cervical cancer Over 200 genotypes of HPV, 40 affect ano-genital tract High risk HPV: 16,18,31,33,35,39,45,51,52,56,58,59,68,73,82
HPV Anal cancer – 90% Vaginal cancer – 70% Penile cancer – 50% Vulvar cancer – 40% Head and neck/orophayngeal cancers – 13 – 72%
HPV
HPV Over 80% of HPV infections will clear within 12- 18 months
HPV Persistent infection with high-risk HPV is the most important risk factor for cervical cancer
SO WHY CHANGE?? 3. NEW TECHNOLOGIES HPV DNA test Liquid based cytology & computer-assisted image analysis
SO WHY CHANGE?? 3. NEW TECHNOLOGIES HPV DNA test Much higher sensitivity compared with Pap smears (95% v 55%): better test High negative predictive value (>99%), allowing for longer screening interval
SO WHY CHANGE?? 4. NATIONAL HPV VACCINATION PROGRAM 3 dose quadrivalent vaccination (Gardasil): HPV 6,11,16,18 2007 – girls (12-26yrs), 2013 – girls and boys (12-13 years) Coverage with 3 doses: around 70-80% 86% reduction in HPV 16,18,6,11 92% reduction in genital warts 45% reduction in low grade lesions 85% reduction in high grade lesions
WHAT IS THE CHANGE? Renewal 5 yearly screening Based on HPV DNA test Women 25 – 74 yrs Option for self-collected sample (for never screened or under-screened women) National Register
HPV test Identical procedure to Pap test - sample from SC junction using cervical sampler, spatula +/- cytobrush Then sample is placed in liquid based medium HPV DNA testing (with partial genotyping) is performed If positive for oncogenic HPV type, reflex liquid based cytology (LBC) is performed on the same sample

Self collected swab Dry flocked swab inserted into vagina Cannot perform LBC on sample Medicare rebate for “never or under screened women” If +ve HPV 16/18 – refer for colposcopy If +ve for oncogenic HPV (not 16/18) – invite back for reflex LBC under direct vision Sensitivity 88% – better than Pap, not as good as physician collected sample
SPECIAL CASES Pregnancy Immune-deficient/HIV DES in utero Symptomattic women (any age) History childhood sexual abuse/first sexual activity <14 yrs

NATIONAL REGISTER Single electronic record Send out invitations, reminders, and FOBT kits Allow practitioners access to patients records/results through medical software Upload data to Register through medical software Allow patients to access screening record/results
TRANSITIONING TO THE NEW PROGRAM Women who: are aged 25+ years will be invited into the new program 2 years after their last Pap test have had a Pap test below the age of 25 will be invited into the program at the routine screening age of 25 (explanatory letter to be sent by National Register)
TRANSITIONING TO THE NEW PROGRAM Women who: are in follow-up for LSIL should have co-test (HPV + LBC) at next scheduled follow-up; refer for colposcopy if + for any oncogenic HPV type; if negative return to 5- yearly screening have been treated for HSIL (CIN2/3) in the pre-renewal program should start or continue Test of Cure (annual co-test until 2 consecutive negatives) have been treated for adenocarcinoma in situ will have annual co-testing (HPV and LBC) indefinitely

THE NEW SCREENING PROGRAM We have a BETTER TEST
THE NEW SCREENING PROGRAM We have a BETTER TEST
THE NEW SCREENING PROGRAM We have a BETTER TEST It will further reduce rates of cervical cancer (additional 20% reduction) - Increased detection of adenocarcinoma
THE NEW SCREENING PROGRAM The better test means we can SAFELY SCREEN LESS OFTEN - So we allow women adequate time to clear the virus themselves (much like the common cold)
THANK YOU
