Mutation Scores and Differential Protein Evaluating Efficacy in Adjuvant Chemotherapy in HER2(-) Luminal B Breast Cancer

Chemotherapy Effect Clinical Trial

Official title: Mutation Scores and Differential Protein Evaluating Efficacy in Neo-adjuvant Chemotherapy and the Non-PCR Patients Treated With Sequential Nalvelbine and Xeloda in HER2(-) Luminal B Breast Cancer

Status Not yet recruiting

Clinical Trial Summary

We plan to carry out a prospective, randomized, open phase III clinical trial which sponsored by the Tianjin Medical University Cancer Hospital and Institute. The primary aim is to evaluate pCR of DT and ET regimen as neoadjuvant chemotherapy in the treatment of HER2 negative Luminal B breast cancers and the correlation of pCR respectively with the susceptible gene mutation scores and differential protein identified by proteomics. For patients with pCR, the association between the 5 year DFS and susceptible gene mutation scores and differential protein identified by proteomics will be evaluated. All Non-pCR patients will receive NX chemotherapy for 4 cycles, and to evaluate correlations between 5 year DFS of these patients respectively with susceptible gene mutation scores and differential protein identified by proteomics, and to evaluate the safety of neoadjuvant chemotherapy and sequential adjuvant NX regimen therapy. Meanwhile, we will verify susceptible gene mutation scores and differential protein identified by proteomics are significant predictors of HER2 negative Luminal B breast cancer chemotherapy sensitivity and prognosis, and explore the feasibility of susceptible gene mutation scores and differential protein in clinical application.

Clinical Trial Description

This is a prospective, randomized, open phase III clinical trial which will be sponsored by the Tianjin Medical University Cancer Hospital and Institute. The primary aim is to evaluate pCR of Pegylated Liposomal Doxorubicin and Docetaxel (DT) Compared to Conventional Doxorubicin and Docetaxel (ET) regimen as neoadjuvant chemotherapy in the treatment of HER2 negative Luminal B breast cancers and the correlation of pCR respectively with the susceptible gene mutation scores and differential protein identified by proteomics. For patients with pCR, the association between the 5 year DFS and susceptible gene mutation scores and differential protein identified by proteomics will be evaluated. All Non-pCR patients will receive NX chemotherapy for 4 cycles, and to evaluate correlations between 5 year DFS of these patients respectively with susceptible gene mutation scores and differential protein identified by proteomics, and to evaluate the safety of neoadjuvant chemotherapy and sequential adjuvant Nalvelbine and Xeloda (NX) regimen therapy. Meanwhile, we will verify susceptible gene mutation scores and differential protein identified by proteomics are significant predictors of HER2 negative Luminal B breast cancer chemotherapy sensitivity and prognosis, and explore the feasibility of susceptible gene mutation scores and differential protein in clinical application. ;
