AI Article Synopsis
- Osteosarcopenia, a condition combining sarcopenia and osteopenia, is linked to poor survival rates in patients who have undergone biliary tract cancer (BTC) resection.
- A study of 109 patients revealed that 28% had osteosarcopenia, which was associated with higher rates of lymph node metastasis and worse disease-free and overall survival outcomes.
- The findings indicate that osteosarcopenia is an important prognostic factor for predicting adverse outcomes following BTC surgery.
Article Abstract
Purpose: Frailty, characterized by sarcopenia and osteopenia, is associated with poor survival after the resection of biliary tract cancer (BTC). Osteosarcopenia, the coexistence of sarcopenia and osteopenia, has recently been associated with poor outcomes in various cancers. This study assessed the prognostic value of osteosarcopenia after the resection of BTC.
Methods: We analyzed 109 patients who underwent BTC resection between 2014 and 2021 for the following conditions: intrahepatic cholangiocarcinoma (n = 21), perihilar cholangiocarcinoma (n = 16), distal cholangiocarcinoma (n = 32), gallbladder carcinoma (n = 17), and ampullary carcinoma (n = 23). Sarcopenia was evaluated using computed tomography of the psoas muscle at the third lumbar vertebra, while osteopenia was measured using bone mineral density at the 11th thoracic vertebra. Osteosarcopenia was defined as the presence of both the conditions.
Results: Sarcopenia was present in 54 patients (50%), osteopenia in 50 patients (46%), and osteosarcopenia in 30 patients (28%). Lymph node metastasis is common in patients with osteosarcopenia. A multivariate analysis revealed that lymph node metastasis (p = 0.0278), poor tumor differentiation (p = 0.0027), and osteosarcopenia (p = 0.0436) were independent predictors of poor disease-free survival. Osteosarcopenia was also a significant predictor of poor overall survival (p < 0.0001).
Conclusion: Osteosarcopenia serves as a prognostic factor for poor outcomes after BTC resection.

Objectives: Osteosarcopenia is a combination of sarcopenia and osteoporosis that increases mortality rates among older people compared with either alone. This study aimed to identify the contribution of osteosarcopenia to the development and severity of dysphagia.
Methods: We retrospectively reviewed the medical charts of 211 patients aged ≥ 65 years who were referred to the dysphagia rehabilitation team.

Article Synopsis
- * Denosumab is an anti-osteoporotic drug that reduces bone loss and may also improve aspects of sarcopenia, showing promise as a treatment for both conditions.
- * Current research on Denosumab's effectiveness for sarcopenia, particularly in China, is limited, highlighting the need for further studies to better understand its mechanisms and impacts.

Purpose: Recently, several investigators have focused on the clinical significance of osteosarcopenia in malignancies; however, its prognostic impact on patients with gastric cancer after conversion surgery (CS) remains unclear. Therefore, we aimed to investigate sarcopenia, osteopenia, and osteosarcopenia in this patient population.
Methods: We retrospectively analyzed 24 patients with gastric cancer who underwent CS.

Various metabolic abnormalities including obesity, insulin resistance, hypertension, dyslipidemia, hyperthyroidism, and low vitamin D levels have been linked to both osteopenia and sarcopenia. Osteo-sarcopenia is also commonly observed due to aging that notably include postmenopausal women. GLP-1, a labile incretin secreted from the intestinal L-cells stimulates insulin secretion and sensitivity, making it an effective anti-diabetic medication.
