Response To Neoadjuvant Chemotherapy

There are no means to predict patient response to neoadjuvant chemotherapy (NAC); the impact of skeletal muscle loss on the response to NAC remains undefined. We investigated the association between response to chemotherapy and skeletal muscle loss in breast cancer patients. Patients diagnosed with invasive breast cancer who were treated with NAC, surgery, and radiotherapy were analyzed. We quantified skeletal muscle loss using pre-NAC and post-NAC computed tomography scans. The response to treatment was determined using the Response Evaluation Criteria in Solid Tumors. We included 246 patients in this study (median follow-up, 28.85 months). The median age was 48 years old (interquartile range 42–54) and 115 patients were less than 48 years old (46.7%). Patients showing a complete or partial response were categorized into the responder group (208 patients); the rest were categorized into the non-responder group (38 patients). The skeletal muscle mass cut-off value was determined using a receiver operating characteristic curve; it showed areas under the curve of 0.732 and 0.885 for the pre-NAC and post-NAC skeletal muscle index (p < 0.001 for both), respectively. Skeletal muscle loss and cancer stage were significantly associated with poor response to NAC in locally advanced breast cancer patients. Accurately measuring muscle loss to guide treatment and delaying muscle loss through various interventions would help enhance the response to NAC and improve clinical outcomes.

Exercise Protocol

Many breast cancer patients gain weight during treatment increasing recurrence, oncology specific mortality and general mortality risks. Breast cancer diagnosis and treatment overthrow patients’ lifestyle aggravating sedentariness and any preexisting weight gain causes like insulin and leptin resistance, dysbiosys and dyslipidemia. The aim of this study is to evaluate the efficiency of a moderately high protein diet – based on foods naturally high in proteins, omega-3 fatty acids, calcium, probiotics and prebiotics – and of an isometric exercise protocol to generate fat loss without muscle loss in ER+ breast cancer patients taking antiestrogenic treatment. We randomized 50 ER+ breast cancer patients – taking either Tamoxifen or Aromatase Inhibitors (AI) after surgery and chemotherapy – to follow a high protein diet, or a high protein diet and 4’ isometric exercises for 12 weeks. Patients were instructed to eat only when hungry and to keep a food journal. We measured weight and body composition with a bioelectrical impedance scale after checking for hydration status. The diet group lost 2.17 ± 2.42% subcutaneus fat (p = 0,000) with no muscle loss, and there was no statistical difference between patients taking Tamoxifen or AI regarding body composition evolution. The diet + isometric exercise group lost 2.2 more pounds than the diet group and 0.66 ± 0.91% visceral fat (p = 0,001) also with no muscle loss. AI patients from the diet and exercise grup did not improve muscle mass – maybe because of the musculoskeletal impact of AI medication. In conclusion, a moderately high protein diet can decrease body fat in ER+ breast cancer patients on antiestrogenic medication. Adding a daily minimal exercise protocol to a high protein diet decreases visceral fat – which is more hormonally active. And resistance-training exercises are more appropriate than isometric exercises for patients on AI.
