Construction and application method of breast cancer prognosis model and storage medium

Abstract

The invention relates to a breast cancer prognosis model construction and application method and a storage medium, and the construction method comprises the steps: obtaining a breast cancer training data set, and carrying out the preprocessing of the data of each patient in the breast cancer training data set, and the data of each patient comprises a plurality of features; dividing the breast cancer training data set into different groups based on the plurality of features, the different groups being determined based on infiltration levels of different immune cells; differential expression genes between the different groups are analyzed, candidate genes are obtained through filtering, and the differential expression genes comprise the differential expression genes related to immune infiltration and the differential expression genes participating in a transfer mechanism; and constructing a risk scoring model based on the candidate genes. By integrating immune related gene signals related to metastasis, the prognosis effect of a patient can be evaluated more accurately, and treatment of the patient can be guided.

Description

technical field [0001] The application relates to the construction of a breast cancer prognosis model, its application method and storage medium. Background technique [0002] Cancer has gone through a long human history and is still the leading cause of death. Breast cancer is one of the most common malignant tumors in women worldwide. Breast cancer is also the second most common cause of cancer-related death in women. Although tremendous advances in medicine over the years have reduced mortality, the high heterogeneity of breast cancer still makes prognosis and treatment challenging. [0003] Over the past decade, considerable work has been done to develop prognostic indicators of breast cancer progression. Most (about 80%) breast cancers become invasive, and about 20-30% result in distant metastases after treatment. Metastasis is therefore the deadliest development of breast cancer, drastically reducing long-term survival from 90% to 5%. However, most of the distincti...
