Purpose

This randomized phase III trial studies how well cisplatin or carboplatin (platinum based chemotherapy) works compared to capecitabine in treating patients with remaining (residual) basal-like triple-negative breast cancer following chemotherapy after surgery (neoadjuvant). Drugs used in chemotherapy, such as cisplatin, carboplatin and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether cisplatin or carboplatin is more effective than capecitabine in treating patients with residual triple negative basal-like breast cancer.

Inclusion Criteria

  • Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 within 2 weeks prior to screening - Female and male patients must have histologically confirmed invasive breast cancer that meets the following criteria: - Clinical stage II-III (American Joint Committee on Cancer [AJCC] 7th edition) at diagnosis, based on initial evaluation by clinical examination and/or breast imaging; no metastatic disease allowed - ER- and PR- should meet one of the following criteria: - =< 10% cells stain positive, with weak intensity score (equivalent to Allred score =< 3) - =< 1% cells stain positive, with weak or intermediate intensity score (equivalent to Allred score =< 3) - HER2 negative (not eligible for anti-HER2 therapy) will be defined as: - Immunohistochemistry (IHC) 0, 1+ without in situ hybridization (ISH) HER2/neu chromosome 17 ratio OR - IHC 2+ and ISH HER2/neu chromosome 17 ratio non-amplified with ratio less than 2.0 and if reported average HER2 copy number < 6 signals/cells OR - ISH HER2/neu chromosome 17 ratio non-amplified with ratio less than 2.0 and if reported average HER2 copy number < 6 signals/cells without IHC - NOTE: Patients that originally present with synchronous bilateral tumors are eligible provided both tumors are TNBC, and at least one of them fulfills the remainder eligibility criteria of the protocol; multifocal or multicentric breast cancers are eligible as long as all tumors fulfill eligibility criteria - NOTE: Patients that have a discrepancy in ER/PR/HER2 status between original diagnosis and surgical specimen (if ER/PR/HER2 status were repeated) are not eligible for study participation (i.e. ER/PR/HER2 has to fulfill above criteria in both scenarios) - Patients must have completed neoadjuvant taxane +/- anthracycline; patients must NOT have received cisplatin or carboplatin or capecitabine as part of their neoadjuvant therapy regimen - NOTE: Patients who received preoperative therapy as part of a clinical trial may enroll - NOTE: Patients that were not able to complete their planned neoadjuvant chemotherapy for any reason (i.e. toxicities, etc.) are eligible to participate as long as no further systemic standard of care therapy is planned by the treating physician - Must have completed definitive resection of primary tumor - Negative margins for both invasive and ductal carcinoma in situ (DCIS) are desirable, however patients with positive margins may enroll if the treatment team believes no further surgery is possible and patient has received radiotherapy; patients with margins positive for lobular carcinoma in situ (LCIS) are eligible - Either mastectomy or breast conserving surgery (including lumpectomy or partial mastectomy) is acceptable - Sentinel node biopsy either pre or post neoadjuvant chemotherapy (i.e. at the time of definitive surgery) are allowed;

Detailed Description

PRIMARY OBJECTIVES: I. To compare the invasive disease-free survival (IDFS) in triple-negative breast cancer (TNBC) patients with residual basal-like disease after neoadjuvant chemotherapy who are randomized to post-preoperative platinum based chemotherapy with those who are randomized to capecitabine. SECONDARY OBJECTIVES: I. To evaluate overall survival (OS) and response-free survival (RFS) in the two arms in patients with TNBC with residual basal-like disease after neoadjuvant chemotherapy. II. To characterize the side effects and tolerability of platinum agent as well as capecitabine in patients with TNBC with residual disease after neoadjuvant chemotherapy. III. To identify the rate of basal-like gene expression using prediction analysis of microarray 50 (PAM50) analysis by digital messenger ribonucleic acid (mRNA) quantitation amongst drug-resistant residual TNBC after neoadjuvant chemotherapy. IV. To assess the difference in health-related quality of life (HRQL) between the platinum based and capecitabine chemotherapy arms. EXPLORATORY OBJECTIVES: I. To compare the IDFS in TNBC patients with residual non-basal-like disease after neoadjuvant chemotherapy who are randomized to post-preoperative platinum based chemotherapy with those who are randomized to capecitabine. II. To describe the rate of neurotoxicity over time in the platinum arm, the rate of medication adherence in the capecitabine arm and the rates of amenorrhea in both arms. III. To evaluate the association of genomic alterations identified via profiling of the surgical tumor specimen with RFS in patients with TNBC after neoadjuvant chemotherapy. IV. To explore whether any of the genomic alterations identified via profiling of the surgical tumor specimen can predict treatment benefit in patients with basal subtype TNBC. V. To determine the frequency of CTC positivity at baseline and after completion of study therapy in patients with TNBC with residual basal subtype disease after neoadjuvant chemotherapy. VI. To evaluate the associations between CTC levels at baseline, and after completion of chemotherapy, with RFS. VII. To evaluate the association between CTC change in status posttreatment (i.e. negative to negative, negative to positive, positive to negative, positive to positive) and RFS. VIII. To explore significance of CTC number/phenotype and ctDNA detected mutations (mutational burden, specific mutations) in predicting RFS. IX. To determine the frequency of plasma tumor cell-free DNA (cfDNA) positivity at baseline and after completion of study therapy in patients with TNBC with residual basal subtype disease after neoadjuvant chemotherapy. X. To evaluate the associations between plasma tumor cfDNA tumor specific mutations (baseline and after therapy) with RFS. XI. To explore optimal biomarker combination for RFS prediction. XII. To determine the effects of tobacco, operationalized as combustible tobacco (1a), other forms of tobacco (1b), and environmental tobacco exposure (ETS) (1c) on provider-reported cancer-treatment toxicity (adverse events (both clinical and hematologic) and dose modifications). XIII. To determine the effects of tobacco on patient-reported physical symptoms and psychological symptoms. XIV. To examine quitting behaviors and behavioral counseling/support and cessation medication utilization. XV. To explore the effect of tobacco use and exposure on treatment duration, relative dose intensity, and therapeutic benefit. OUTLINE: Patients are randomized to 1 of 3 treatment arms. ARM A (closed to accrual 05/16/2016): Patients undergo observation. ARM B: Patients receive cisplatin intravenously (IV) or carboplatin IV on day 1. Treatment repeats every 3 weeks for 4 courses in the absence of disease progression or unacceptable toxicity. ARM C: Patients receive capecitabine orally (PO) twice daily (BID) on days 1-14. Treatment repeats every 3 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for up to 10 years.
