Is this trial a fit for you?

Likely a good fit

Older adults (≥ 70 years) with histologically confirmed adenocarcinoma of the breast.

Probably not a fit

Patients who cannot tolerate dose-dense regimens or have unsuitable organ function or performance status may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase 2 trial examines dose-dense CMF (cyclophosphamide, methotrexate, and fluorouracil) in two standard regimens for patients aged 70 and above with breast cancer. It includes participants with adenocarcinoma of the breast, including triple-negative cases, and requires specific receptor testing. The study uses CMF alongside paclitaxel and is conducted at Memorial Sloan Kettering locations in New Jersey. Eligibility focuses on performance status, age, histology confirmation, and prior treatments relevant to the cohorts.

Why it matters

Potential benefit: If feasible and safe, patients may receive effective chemotherapy that fits their age group and disease subtype.

How similar studies have gone: Previous breast cancer regimens in older adults have shown mixed feasibility; this study explores practicality in a targeted older population.

Inclusion Criteria:

* Patients must have histologically confirmed adenocarcinoma of the breast confirmed at MSK. The patient must have had diagnostic biopsy or completion of primary surgical management, within 3 months of enrollment. Results of HER-2/neu, estrogen receptor, and progesterone receptor are required for study entry.
* Patients must be ≥ 70 years of age.
* Patients must have ECOG performance status \>2 (Karnofsky score of ≥ 60%).
* Patients may have received hormonal therapy for the purpose of chemoprevention.
* Adjuvant/neoadjuvant chemotherapy decision to treat based on the discretion of investigator
* Cohort 1 only: Patients have any histology except Her 2 Neu positive in the adjuvant or neoadjuvant setting
* Cohort 2 only: Patients have triple negative (ER- (10%) PR-Her 2 Neu -) in the neoadjuvant setting
* Cohort 2 only: Patients have received at least 1 dose of carboplatin/paclitaxel +/- pembrolizumab in the neoadjuvant setting

Required Organ Function

Adequate hematologic function defined as follows:

* Absolute neutrophil count (ANC) ≥ 1,500 cells/mm3
* Platelets ≥ 100,000 cells/mm3

Adequate renal function defined as follows:

° Creatinine clearance (CrCL) of \>30 mL/min by the Cockcroft-Gault formula:

CrCl (mL/min) = \[(\[140 - age(years)\] x weight (kg))/72 x creatinine (mg/dL)\] (x 0.85 for female patients)

Adequate hepatic function defined as follows:

* Total bilirubin ≤ 1.5 x institutional upper limit of normal (ULN) (patients with known Gilbert's disease who have bilirubin level ≤ 3 x institutional ULN may be enrolled)
* AST and ALT ≤3 x institutional ULN

  * Patients or their Legally Authorized Representative must give written, informed consent indicating their understanding and willingness to participate in the study.

Exclusion Criteria:

* Stage IV breast cancer
* CARG score- high Frail 4 or more as assessed by CAIT
* Her 2 Neu positive 3+/amplified breast cancer
* No prior chemotherapy within 1 year of study enrollment
* Cohort 2 only: patients may not receive pembrolizumab during dd CMF treatment
