Enhancer RNAs(eRNAs)are a class of non-coding RNA,which play a critical role in tumor progression.1 Previous studies have indicated abundant CpG methylation,somatic mutation,and copy number variation in eRNA regions in cancers.2,3 We constructed a landscape of genetic alteration-driven eRNAs and provided an integrative pipeline to identify drug candidates that affect eRNA ***,we explored the prognostic value of genetic alteration-driven eRNAs.

Objective: To establish the dynamic treatment strategy of Chinese medicine(CM) for metastatic colorectal cancer(m CRC) by machine learning algorithm, in order to provide a reference for the selection of CM treatment strategies for m CRC. Methods: From the outpatient cases of m CRC in the Department of Oncology at Xiyuan Hospital, China Academy of Chinese Medical Sciences, 197 cases that met the inclusion criteria were screened. According to different CM intervention strategies, the patients were divided into 3 groups: CM treatment alone, equal emphasis on Chinese and Western medicine treatment(CM combined with local treatment of tumors, oral chemotherapy, or targeted drugs), and CM assisted Western medicine treatment(CM combined with intravenous regimen of Western medicine). The survival time of patients undergoing CM intervention was taken as the final evaluation index. Factors affecting the choice of CM intervention scheme were screened as decision variables. The dynamic CM intervention and treatment strategy for m CRC was explored based on the cost-sensitive classification learning algorithm for survival(CSCLSurv). Patients' survival was estimated using the Kaplan-Meier method, and the survival time of patients who received the model-recommended treatment plan were compared with those who received actual treatment plan. Results: Using the survival time of patients undergoing CM intervention as the evaluation index, a dynamic CM intervention therapy strategy for m CRC was established based on *** CM intervention strategies for m CRC can be selected according to dynamic decision variables, such as gender, age, Eastern Cooperative Oncology Group score, tumor site, metastatic site, genotyping, and the stage of Western medicine treatment at the patient's first visit. The median survival time of patients who received the modelrecommended treatment plan was 35 months, while those who receive the actual treatment plan was 26.0 months(P=0.06). Conclusions:
