17 Objectives Choose to receive treatments for breast cancer Decision Maintain quality of life Five year survival Able to care For oneself Fundamental Objectives Means Objectives Able to work go places with family

18 Influence Diagram Diagnosed with breast cancer Receive treatments? Diagnose stage of breast cancer Remission Death

19 Pre-cancerous cells only Surgery Radiation Chemotherapy May have to have this treatment = Stage 0 Treatment Influence Diagram

20 Stage I Treatment Influence Diagram Tumor < 2 cm 92% Stage I May have to have this treatment = Surgery Radiation Chemotherapy

21 Stage II Treatment Influence Diagram Tumor < 2 cm 92% Surgery, Radiation & Chemotherapy 2 cm <Tumor < 5 cm 77% Tumor > 5 cm 55% Lymphnodes Lymph nodesunderarm Stage IIA Stage IIB Stage IIA Stage IIB

22 Stage III Treatment Influence Diagram Tumor > 5 cm 55% Lymph nodes underarm attached to each other Surgery, Radiation & Chemotherapy Stage IIIA Tumor < 5 cm Stage IIIA Other tissues Stage IIIB Lymph nodes other than underarm Stage IIIC May also have this condition = Stage IIIB

23 Stage IV Treatment Influence Diagram Surgery, Radiation & Chemotherapy Spread to other organs in the body

24 Planning the Decision Tree  Decisions  Receive treatments or not  Uncertain events  Stage of breast cancer  Survival vs. death  Objectives  Maintain quality of life  Five year survival

25 Decision Tree Diagnosed with breast cancer. Choose to receive treatment or not? Survival Death CONTINUED… 0 6 EMV = 5 EMV = 1.84 EMV= 2.16 EMV= 0.20 EMV= 1.08 EMV = 2.43 EMV= 1.08 20% 37% 27% 11% 5% Receive treatments Don’t receive treatments Stage 0 Stage I Stage II Stage III Stage IV 1% 99% “Values” assigned to each outcome: 6 = survival with no treatment 5 = surgery 4 = chemotherapy 3 = surgery & radiation 2 = surgery & chemotherapy 1 = surgery, radiation & chemotherapy 0 = death

31 Conclusion: DECISION ASSUMPTIONS: WhiteWhite WomanWoman Age 35-40 yearsAge 35-40 years If diagnosed in the next 5 years, the decision would be to receive treatments with an EMV = 2.43. No matter what stage of cancer the testing reveals, still choose to receive treatments.
