Background Quarterly, the Canadian Partnership Against Cancer collects information from the provinces/territories on the status of population-based breast cancer screening programs and/or strategies. The information is collected through provincial and territorial leads represented on the National Committee of Canadian Breast Cancer Screening Initiative supported by the Canadian Partnership Against Cancer. March 2013

Canadian Task Force on Preventive Health Care Guidelines The Canadian Task Force on Preventive Health Care (2011) recommends the following for breast cancer screening: Mammography For women aged 40-49, routine screening not recommended (Weak recommendation; moderate quality evidence) For women aged 50-69, routine screening every 2 to 3 years (Weak recommendation; moderate quality evidence) For women aged 70-74, routine screening every 2 to 3 years (Weak recommendation; low quality evidence) Magnetic Resonance Imaging Routine screening not recommended (Weak recommendation; no evidence) March 2013
5
Canadian Task Force on Preventive Health Care Guidelines (Cont’d) Clinical Breast Exam Routine screening for breast cancer is not recommended when performing clinical breast exam alone or in conjunction with mammography (Weak recommendation; low quality evidence) Breast Self Exam Routine practice of breast self exam is not advised by the Task Force (Weak recommendation; moderate quality evidence) March 2013

Quality Assurance: General Conduct a review of screening films/digital images of interval cancers* Conduct a review of missed at assessment cancers Require a ‘double read’ of a portion of all screens Have a questionnaire to evaluate client satisfaction Conduct analyses to estimate the effect of organized breast screening on mortality Nunavut Northwest Territories Yukon British Columbia Alberta** Saskatchewan Manitoba Ontario (Done at individual centres) Québec New Brunswick (Provincial Cancer Report) Nova Scotia *** (periodically) Prince Edward Island Newfoundland and Labrador (in the process) *Classify cancer as either true interval or missed at screening **Alberta Health Services Screen Test sites only ***NS review of all interval cases 1991 to 2004 and CD of various cases are sent to all screening radiologists. Now with full field digital this will be competed electronically.

Quality Assurance: Evaluation of Radiologist Performance Most P/Ts evaluate radiologists on their level of performance on an annual basis with the exceptions of YK and PEI. NB collects this data but does not report on it Positive Predictive Value (PPV) Abnormal call rate Cancer detection rate Interval cancers General performance reviews Other (specified) Northwest Territories British Columbia Sensitivity/ Specificity Alberta Sensitivity/ Specificity Saskatchewan Manitoba Ontario Sensitivity/ Specificity and One year recall rate Québec Nova Scotia Newfoundland and Labrador Sensitivity/ Specificity Table: Specific information collected when evaluating radiologist performance per province/territory Table: Specific volume requirement for radiologists per province/territory NLNSNBQCONMBSKABBCNT 1,500 / year2,500 / year1200/ year** 500/ year 1,000 / year1,000 / year*3,000 / year480 / year**2,500 / year480 / year *All radiologists greatly exceed this number **Includes diagnostic and screening mammograms
17
Quality Assurance: Vital and Cancer Registry-Linkages with Provincial Registries Collection of ‘Vital Status’ variable Collection of ‘Date of Death’ variable Collection of cancer stage (TNM or Collaborative stage) or other cancer variables Nunavut Northwest Territories Yukon ** British Columbia Alberta ** ** Saskatchewan Manitoba Ontario Québec New Brunswick *** Nova Scotia Prince Edward Island Newfoundland and Labrador *Through provincial client registry **Decreased lists are provided to WGH monthly ***linkage for post-screen cancer information only March 2013
18
Mammography Screening Program: Vital and Cancer Registries – TNM or Collaborative Stage For the provinces and territories that do not currently link with provincial cancer registries to collect cancer stage (TNM or Collaborative Stage) or other cancer variables, it may still be possible: For the collection of post-screen cancer information (BC, QC, NS*) For the collection of cancer and stage information (BC, NS*) *Note: Both linkages are possible in NS; however, an agreement has not yet been established For YK it is unknown if this is possible March 2013
19
Breast MRI: High Risk Guidelines Self-reported family history (>=2) of breast cancer (first degree relative) Self- reported family history of BRCA 1/2 Genetic testing BRCA 1 or 2 Risk of breast cancer >20% (scored by validated assessment tools) Chest irradiation between the ages of 10 and 30 years Li-Fraumeni syndrome, Cowden syndrome, or Bannayan- Riley- Ruvalcaba syndrome British Columbia **** Alberta Ontario ** **** *** Nova Scotia ** Newfoundland and Labrador >=3 Prince Edward Island Currently there are five provinces (BC, AB, ON, NS, NL) that have developed standard guidelines for MRI referral Table: The criteria or evidence that MRI referral is based upon per province * First degree relative ** >25% using validated assessment tool *** Chest irradiation before age 30 and at least 8 years ago **** BC includes the following syndromes: Li Fraumeni Syndrome, Cowden’s Syndrome, HDGC (CDH-1), Peutz-Jegher’s Syndrome March 2013

Future Implementation of MRI Ontario has implemented an MRI screening component to its organized screening program for women considered at high risk for breast cancer. BC, NS and AB have established guidelines for the use of MRI among women considered to be at elevated risk (i.e. in BC the women considered are confirmed cases of BRCA1 and BRCA2 mutation only). For more information on MRI guidelines for NS please visit www.breastscreening.ns.cawww.breastscreening.ns.ca NL is exploring the appropriateness of using MRI among women considered to be at elevated risk March 2013
