Choosing Wisely – Implication based on Indian data in our patients with breast cancer (INR vs. USD)
2020
Objectives: Breast cancer is increasing in India due to aging population, better awareness among general public, willingness to seek treatment of cancers, and easier access to cancers centers. We present our single-center data over a 2-year period and discuss cost implications taking the example of metronomic chemotherapy maintenance and predictive markers in early breast cancer. Material and Methods: Prospectively collected data of all consecutive patients with breast cancer registered between September 2017 and August 2019 were evaluated. Clinical features, stage, receptor status, and other features were tabulated. Statistical analysis was using SAS version 9.4 – Chi-square test and Fisher’s exact test were performed. P ≤ 0.05 was considered as statistically significant. Results: For the 484 consecutive patients, the median age was 50 years. This included EBC (201, 42%), LABC (141, 29%), and MBC (142, 29%). ER expression was seen in 52% of cases (253/484), PR in 47% (229/484), and Her2 was positive in 47% (229/484). Finally, 83 patients (17%) were identified as TNBC. HR-positive Her2-negative EBC constituted 111/484 patients (23%). Discussion: If our 83 TNBC patients were given metronomic maintenance chemotherapy, their 3-year overall survival (OS) is projected to increase from 54% to 100% at a cost of INR 8191/- per patient (equivalent to USD 109/-). If our 111 HR-positive Her2-negative EBC patients were evaluated for risk by biomarker test validated in Indian patients, 76 of these would be spared the toxicity of adjuvant CT. This would also result in saving on the cost of chemotherapy medication of INR 4,035,296/- in India (equivalent to USD 53,699/- if treated in USD). In addition, they would also have better quality of life (QoL). Conclusion: It is possible to identify patients with low risk early breast cancer using Can assist and save them from unnecessary cost and/or toxicity.
