Correlation of Predictive Accuracy of PREDICT Version 2.2 of Indian Women With Operable Breast Cancer

This is an observational retrospective study which aims at comparing the 5-year survival estimates from "PREDICT V2.2" with observed 5-year outcome from our dataset of Indian women treated for operable breast cancer. "PREDICT V2.2" is a prognostication and treatment benefit tool developed in the UK. It is a tool available online (www.predict.nhs.uk) providing 5-and 10-year survival estimates and treatment benefit predictions, for operable breast cancer patients. We hypothesize that 5-year overall survival (OS) predictions using "PREDICT V2.2" will have reasonable accuracy and applicability to the Indian operable breast cancer patients. The predictions, if accurate, will not only reassure the patients of the benefits of the treatment being offered, which outweigh the side effects but it will also make clinician as well as patient confident about avoiding potentially toxic systemic therapies, where the benefit is too small.
