Chemo's muscle impact under the microscope in small breast cancer study

This study looked at how a single round of chemotherapy affects the muscles of women with early-stage breast cancer. Researchers compared three common chemo regimens: paclitaxel alone, paclitaxel plus trastuzumab, and paclitaxel plus carboplatin. They took muscle biopsies and measured strength, body composition, and quality of life before and four days after treatment. The study was terminated early and only enrolled 5 participants, so the findings are very limited.
