Summary
Brief summary (as posted)
Postoperative muscle loss is common in patients with bone metastases undergoing lower limb bone cancer curettage, affecting both limb skeletal muscles and potentially swallowing-related muscles. Rectus femoris thickness, measured via ultrasound on postoperative day seven, is used to assess this loss. Branched-chain amino acids (BCAAs) are important for muscle protein synthesis, but little research exists on whether postoperative oral BCAA supplementation can reduce muscle loss, swallowing function deterioration, and short-term complications. This study investigates if BCAA supplementation from postoperative day one to day 30 can reduce muscle loss (primary endpoint: rectus femoris thickness on day seven) and mitigate swallowing function decline, pharyngeal muscle contraction loss, and complications within three months post-surgery.

Show eligibility criteria text
Inclusion Criteria: * I) The patient has a femoral metastasis and is expected to undergo bone tumor curettage and joint replacement surgery, or the patient has a femoral metastasis and is expected to undergo bone tumor curettage and internal fixation surgery; II) Age between 20 and 80 years; III) Able to take care of themselves independently (Karnofsky Performance Status ≥ 70%, which measures a patient's ability to perform daily activities, with a total score of 100 points. A higher score indicates better self-care ability, and a score of 70 or above indicates the ability to live independently but not to work or perform normal daily activities); IV) Patients have all signed a written informed consent. Exclusion Criteria: * I) Patients expected to undergo bone tumor curettage and mega prosthesis replacement; II) Patients requiring surgery on both upper and lower limbs; III) Patients requiring surgery on both lower limbs; IV) Patients with simultaneous spinal metastasis; V) Patients likely to undergo a second surgery within 30 days; VI) Patients with metastasis in other locations or a history of metastasis with prior surgeries; VII) Patients with neuromuscular diseases, such as stroke or Parkinson\'s disease; VIII) Exclusion of patients with other diseases and complications, such as those with concurrent gastric cancer or post-gastrectomy patients requiring additional surgeries due to complications or unstable conditions, patients with New York Heart Association Functional Classification ≥ Class 2 heart disease and thrombotic conditions, patients with Hugh-Jones Classification ≥ Grade 4 lung disease, or those currently receiving insulin therapy; IX) Patients allergic to eggs, soy, or thiamine; X) Patients who are already supplementing BCAAs; XI) Patients with psychiatric disorders that may affect their ability to provide informed consent or comply with the study protocol; XII) If postoperative pathology reveals a diagnosis other than the originally identified cancer metastasis, the case will be excluded.
