A Comparative Study on Male Breast Cancer Treatment Alternatives Using a Multi-Criteria Decision-Making (MCDM) Approach

Male breast (MB) cancer is a malignancy that originates from the breast tissue of men. Although men do not have breasts that produce milk rather, glands and ducts in their breast tissue serve as a favourable microenvironment for the proliferation of cancer cells. This study uses a multi-criteria decision-making (MCDM) approach to evaluate the treatment alternatives. The Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) is utilized to evaluate the surgery, targeted therapy (TT), hormonal therapy (HT), chemotherapy (chemo), and radiotherapy according to anaesthesia (Anes), survival rate (SR) (%), risk, cost (∃), treatment duration (TD) (wks.), sensitivity (Sens), and specificity (Spec) as criteria. The result showed that HT ranked highest with 0.0061 as the net flow value while radiotherapy ranked lowest with -0.0063 as the net flow value. The methodology that was proposed for the MCDM is a crucial tool that may be explored by doctors as well as family members and patients to get the preferred treatment alternatives.
