Osteosarcopenia predicts poor prognosis for patients with intrahepatic cholangiocarcinoma after hepatic resection

Impact of imaging-diagnosed sarcopenia on outcomes in patients with biliary tract cancer after surgical resection: a systematic review and meta-analysis

BACKGROUND AND AIMS

Sarcopenia has been associated with poor prognosis in patients with malignant tumors. However, its impact on the outcomes of patients with biliary tract cancer (BTC) undergoing surgical resection remains unclear and warrants further review. This study aims to summarize the available evidence on this issue.

METHODS

A systematic search was conducted in PubMed, Embase, Web of Science, and the Cochrane Library for eligible studies up to March 10, 2024. We extracted data on overall survival (OS), recurrence free survival (RFS), and postoperative major complications from the included studies as the outcomes of interest. Following data synthesis and analysis, we assessed the heterogeneity and performed subgroup analyses. Additionally, the potential for publication bias was evaluated.

RESULTS

A total of 26 studies involving 4292 BTC patients were ultimately retrieved. The findings indicated that sarcopenia was significantly associated with reduced OS in BTC patients after surgery (adjusted HR: 2.03, 95% CI: 1.65-2.48, P < 0.001, I2 = 57.4%). Moreover, sarcopenia may also be linked to poorer RFS (adjusted HR: 2.15, 95% CI: 1.79-2.59, P < 0.001, I2 = 0%) and increased postoperative major complications (OR: 1.22, 95% CI 1.02-1.47, P = 0.033, I2 = 29.2%) as well. Notably, no significant publication bias was detected through funnel plots and Egger's tests.

CONCLUSION

Sarcopenia is associated with poorer OS in BTC patients following surgery. Additionally, it may serve as a prognostic indicator for poorer RFS and increased postoperative major complications. Further studies are warrant to standardize existing definitions and validate these findings.

Impact of osteoporosis on overall survival following endovascular repair for abdominal aortic aneurysms

OBJECTIVE

To evaluate the impact of osteoporosis on overall survival following endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAAs).

METHODS

This was a retrospective, single-center cohort study on 172 patients who had undergone primary EVAR for AAA between 2016 and 2018. Bone mineral density (BMD) was assessed by measuring the Hounsfield units (HUs) of the 11th thoracic vertebra on preoperative computed tomography; a BMD value of <110 HU was considered osteoporosis. All patients were divided into those with osteoporosis and those without osteoporosis, and long-term outcomes were compared. In addition, hazard ratios of each variable for all-cause mortality were evaluated using univariate and multivariate analysis.

RESULTS

All 172 patients were divided into two groups: 72 patients (41.9%) with osteoporosis and 100 patients (58.1%) without osteoporosis. The mean age was higher and mean BMD was lower in osteoporosis patients than non-osteoporosis patients (mean ± standard deviation [SD], 79.2 ± 7.2 vs. 75.0 ± 8.7 years, respectively; P < 0.05; 78.1 ± 26.7 vs. 155.1 ± 36.3 HU, respectively; P < 0.05). During the median follow-up period of 68 months, overall survival was significantly lower in osteoporosis patients than non-osteoporosis patients (osteoporosis: 63.9% and 36.7% at 5 years and 7 years; non-osteoporosis: 83.8% and 74.6% at 5 years and 7 years, respectively; log-rank P < 0.05); freedom from aneurysm-related mortality did not differ significantly between groups (osteoporosis: 94.3% and 89.0% at 5 years and 7 years; non-osteoporosis: 100.0% and 96.7% at 5 years and 7 years, respectively; log-rank P = 0.078). In a multivariate analysis for overall survival following EVAR, coexistence of osteoporosis was found to be an independent risk factor for all-cause mortality (hazard ratio, 1.76, 95% confidence interval, 1.01-3.06; P < 0.05), as well as variables including age, statin use, sarcopenia, and aneurysm diameter.

CONCLUSIONS

Patients with osteoporosis showed a higher all-cause mortality following EVAR than patients without osteoporosis. We believe that comorbidity of osteoporosis may be useful in estimating the life expectancy of patients with AAA.

Impact of osteopenia and osteosarcopenia on the outcomes after surgery of hepatobiliary-pancreatic cancers

Objective

The purpose of this study is to investigate potential associations between osteopenia, osteosarcopenia, and postoperative outcomes in patients with hepatobiliary-pancreatic cancer (HBPC).

Methods

Three online databases, including Embase, PubMed, and the Cochrane Library, were thoroughly searched for literature describing the relationship between osteopenia, osteosarcopenia, and outcomes of surgical treatment of HBPC patients from the start of each database to September 29, 2023. The Newcastle-Ottawa Scale was used to rate the quality of the studies.

Results

This analysis included a total of 16 articles with a combined patient cohort of 2,599 individuals. The results demonstrated that HBPC patients with osteopenia had significantly inferior OS (HR: 2.27, 95% CI: 1.70-3.03, p < 0.001) and RFS (HR: 1.96, 95% CI: 1.42-2.71, p < 0.001) compared to those without osteopenia. Subgroup analysis demonstrated that these findings were consistent across univariate and multivariate analyses, as well as hepatocellular carcinoma, biliary tract cancer, and pancreatic cancer. The risk of postoperative major complications was significantly higher in patients with osteopenia compared to those without osteopenia (OR: 1.66, 95% CI: 1.19-2.33, p < 0.001). Besides, we also found that the presence of osteosarcopenia in HBPC patients was significantly related to poorer OS (HR: 3.31, 95% CI: 2.00-5.48, p < 0.001) and PFS (HR: 2.50, 95% CI: 1.62-3.84, p < 0.001) in comparison to those without osteosarcopenia.

Conclusion

Preoperative osteopenia and osteosarcopenia can predict poorer OS and RFS with HBPC after surgery.

Osteosarcopenia: the coexistence of sarcopenia and osteopenia is predictive of prognosis and postoperative complications after curative resection for colorectal cancer

PURPOSE

To establish if osteosarcopenia is related to postoperative complications, prognosis, and recurrence of colorectal cancer (CRC) after curative surgery.

METHODS

The clinical data of 594 patients who underwent curative resection for CRC between January, 2013 and December, 2018 were analyzed retrospectively to examine the relationship between clinicopathological data and osteosarcopenia. The following definitions were used: sarcopenia, low skeletal muscle mass index; osteopenia, low bone mineral density on computed tomography at the level of the 11th thoracic vertebra; and osteosarcopenia, sarcopenia with osteopenia.

RESULTS

Osteosarcopenia was identified in 98 patients (16.5%) and found to be a significant risk factor for postoperative complications (odds ratio 2.53; p = 0.011). The 5-year overall survival (OS) and recurrence-free survival (RFS) rates of the patients with osteosarcopenia were significantly lower than those of the patients without osteosarcopenia (OS: 72.5% and 93.9%, respectively, p < 0.0001; RFS: 70.8% and 92.4%, respectively, p < 0.0001). Multivariate analysis identified osteosarcopenia as an independent prognostic factor associated with OS (hazard ratio 3.31; p < 0.0001) and RFS (hazard ratio 3.67; p < 0.0001).

CONCLUSION

Osteosarcopenia may serve as a predictor of postoperative complications and prognosis after curative surgery for CRC.

The Impact of Non-bone Metastatic Cancer on Musculoskeletal Health

PURPOSE OF REVIEW

The purpose of this review is to discuss the musculoskeletal consequences of cancer, including those that occur in the absence of bone metastases.

RECENT FINDINGS

Cancer patients frequently develop cachexia, a debilitating condition reflected by weight loss and skeletal muscle wasting. The negative effects that tumors exert on bone health represents a growing interest amongst cachexia researchers. Recent clinical and pre-clinical evidence demonstrates cancer-induced bone loss, even in the absence of skeletal metastases. Together with muscle wasting, losses in bone demonstrates the impact of cancer on the musculoskeletal system. Identifying therapeutic targets that comprehensively protect musculoskeletal health is essential to improve the quality of life in cancer patients and survivors. IL-6, RANKL, PTHrP, sclerostin, and TGF-β superfamily members represent potential targets to counteract cachexia. However, more research is needed to determine the efficacy of these targets in protecting both skeletal muscle and bone.

Analysis of Preoperative Risk Factors for Early Recurrence in Patients After Hepatic Resection for Intrahepatic Cholangiocarcinoma

BACKGROUND

Intrahepatic cholangiocarcinoma (ICC) has a poor prognosis even after curative-intent hepatic resection due to a high recurrence rate. The aim of this study was to investigate preoperative risk factors for early recurrence after surgery for ICC, which may help to identify patients who need preoperative chemotherapy.

METHODS

We retrospectively analyzed 51 patients who had undergone primary surgery for ICC. We investigated the association of preoperative clinical variables with recurrence within 1 year after resection for ICC. We then created a high-risk ICC score using the identified preoperative factors and investigated the association of the score with disease-free and overall survival.

RESULTS

Recurrence within 1 year after surgery for ICC was significantly associated with poor overall survival (P < .01). In the multivariate analysis, preoperative tumor size > 5 cm (P = .03) and elevated C-reactive protein-to-albumin ratio (CAR) (P = .04) were significantly associated with recurrence within 1 year after surgery. A high-risk ICC score of 2 was associated with poor disease-free survival (P < .01) and overall survival (P = .02) compared with a score of 0 or 1.

CONCLUSIONS

Our high-risk ICC score, combining preoperative tumor size and CAR, can be an indicator of early recurrence and poor survival in patients after hepatic resection for ICC. Our findings may provide better preoperative risk stratification of patients with ICC, and the high-risk ICC patients may benefit from preoperative therapy.

Prognostic impact of osteosarcopenia in patients undergoing pancreatic resection for pancreatic ductal adenocarcinoma

BACKGROUND

We investigated the prognostic impact of osteosarcopenia, defined as the combination of osteopenia and sarcopenia, in patients undergoing pancreatic resection for pancreatic ductal adenocarcinoma (PDAC).

METHODS

The relationship of osteosarcopenia with disease-free survival and overall survival was analyzed in 183 patients who underwent elective pancreatic resection for PDAC. Computed tomography was used to measure the pixel density in the midvertebral core of the 11th thoracic vertebra for evaluation of osteopenia and in the psoas muscle area of the 3rd lumbar vertebra for evaluation of sarcopenia. Osteosarcopenia was defined as the simultaneous presence of both osteopenia and sarcopenia. The study employed a retrospective design to examine the relationship between osteosarcopenia and survival outcomes.

RESULTS

Osteosarcopenia was identified in 61 (33%) patients. In the univariate analysis, disease-free survival was significantly worse in patients with male sex (p = 0.031), pathological stage ≥ III PDAC (p = 0.001), NLR, ≥ 2.71 (p = 0.041), sarcopenia (p = 0.027), osteopenia (p = 0.001), and osteosarcopenia (p < 0.001), and overall survival was significantly worse in patients with male sex (p = 0.001), pathological stage ≥ III PDAC (p = 0.001), distal pancreatectomy (p = 0.025), sarcopenia (p = 0.003), osteopenia (p < 0.001), and osteosarcopenia (p < 0.001). In the multivariate analysis, the independent predictors of disease-free survival were osteosarcopenia (p < 0.001) and pathological stage ≥ III PDAC (p = 0.002), and the independent predictors of overall survival were osteosarcopenia (p < 0.001), male sex (p = 0.006) and pathological stage ≥ III PDAC (p = 0.001).

CONCLUSION

Osteosarcopenia has an adverse prognostic impact on long-term outcomes in patients undergoing pancreatic resection for PDAC.

Prevalence and predictive value of sarcopenia in surgically treated cholangiocarcinoma: a comprehensive review and meta-analysis

Background

Sarcopenia, marked by a reduction in skeletal muscle mass and function, is a condition that can manifest in elderly patients with cancer and has been recognized as a possible adverse factor affecting the survival of individuals diagnosed with malignant tumors. This systematic review and meta-analysis aimed to examine the prevalence of sarcopenia in individuals with cholangiocarcinoma while concurrently investigating the potential correlations between the presence of sarcopenia and various critical factors, including survival outcomes and postoperative complications.

Methods

A comprehensive search was conducted across multiple databases, including EMBASE, PubMed, Web of Science, Cochrane Library, and CNKI, employing keywords such as sarcopenia, cholangiocarcinoma, and prognosis. This research explored the prognostic value of sarcopenia on the survival of cholangiocarcinoma. The findings of this meta-analysis were presented using forest plots and a summarized effects model. The Newcastle-Ottawa Scale (NOS) was employed to evaluate the quality of the studies included in the analysis.

Results

A total of 33 articles from five databases were in in the quantitative analysis. A comprehensive meta-analysis revealed that the overall prevalence of sarcopenia among individuals diagnosed with cholangiocarcinoma was43%. Moreover, the analysis revealed a significant and noteworthy correlation between sarcopenia and key clinical parameters such as overall survival (OS), Recurrence-Free Survival (RFS), and Disease-Free Survival (DFS) in patients with cholangiocarcinoma. Subgroup analysis revealed that, when categorized by various ethnicities, diagnostic techniques, and tumor locations, sarcopenia consistently retained its status as a negative predictive factor. Furthermore, sarcopenia has emerged as a risk factor for postoperative complications. All included studies had an NOS score greater than 5, indicating a high quality of evidence.

Conclusion

The results suggest that sarcopenia is significantly related to survival outcomes and postoperative complications in cholangiocarcinoma. Appropriate diagnosis and treatment of sarcopenia should be implemented to improve the prognosis of individuals with cholangiocarcinoma.

Association of chronic liver disease with bone diseases and muscle weakness

The liver is a vital organ involved in nutrient metabolism, hormone regulation, immunity, cytokine production, and gut homeostasis. Impairment in liver function can result in malnutrition, chronic inflammation, decreased anabolic hormone levels, and dysbiosis. These conditions eventually cause an imbalance in osteoblast and osteoclast activities, resulting in bone loss. Osteoporosis is a frequent complication of chronic liver disease (CLD) that adversely affects quality of life and increases early mortality. Sarcopenia is another common complication of CLD characterized by progressive loss of skeletal muscle mass and function. Assessment criteria for sarcopenia specific to liver disease have been established, and sarcopenia has been reported to be associated with an increase in the risk of liver disease-related events and mortality in patients with CLD. Owing to their similar risk factors and underlying pathophysiological mechanisms, osteoporosis and sarcopenia often coexist (termed osteosarcopenia), progress in parallel, and further exacerbate the conditions mentioned above. Therefore, comprehensive management of these musculoskeletal disorders is imperative. This review summarizes the clinical implications and characteristics of osteoporosis, extending to sarcopenia and osteosarcopenia, in patients with CLD caused by different etiologies.

The impact of osteosarcopenia in patients with unresectable or recurrent biliary tract cancer receiving palliative chemotherapy

BACKGROUND

Osteosarcopenia is a newly described syndrome that has been reported to be associated with worse outcomes in various types of cancer. However, its impact on survival in biliary tract cancer remains unclear. This study evaluated the impact of osteosarcopenia on survival in patients with unresectable or recurrent biliary tract cancer.

METHODS

A total of 306 patients with unresectable or recurrent biliary tract cancer who initiated chemotherapy at our institution between 2015 and 2021 were retrospectively investigated. Skeletal muscle index and bone mineral density were measured using pretreatment cross-sectional computed tomography images. Baseline characteristics and survival outcomes were compared between patients with osteosarcopenia and those without. The Cox proportional hazards regression model was used to identify factors associated with survival.

RESULTS

Osteosarcopenia was present in 66 patients (22%) and was associated with older age (74 vs. 69 years, P < 0.001) and female sex (58 vs. 37%, P = 0.003). Patients with osteosarcopenia tended to have worse performance status (P = 0.098), higher modified Glasgow prognostic score (P = 0.082), higher neutrophil to lymphocyte ratio (P = 0.058) and were significantly less likely to receive combination chemotherapy (68 vs. 80%, P = 0.044) than those without. Osteosarcopenia was associated with reduced survival (8.9 vs. 14.0 months, P < 0.001) and was identified as an independent factor predicting shorter survival in multivariate analysis.

CONCLUSIONS

Osteosarcopenia was associated with poor survival in unresectable or recurrent biliary tract cancer treated with chemotherapy. This study highlights the potential importance of screening for osteosarcopenia in patients with biliary tract cancer.

Prognostic Impact of Preoperative Osteosarcopenia for Patients with Pancreatic Ductal Adenocarcinoma After Curative Resection

BACKGROUNDS

The clinical significance of preoperative osteosarcopenia in pancreatic ductal adenocarcinoma (PDAC) has not been fully studied. The purpose of this study was to evaluate the role of preoperative osteosarcopenia in predicting the survival of patients with PDAC.

METHODS

We retrospectively analyzed 265 patients who underwent curative surgical resection for PDAC between 2012 and 2018 in two Japanese institutes. The skeletal muscle index at the L3 vertebrae and the bone mineral density at the Th11 vertebra were calculated for the evaluation of osteosarcopenia before surgery. The relationship between perioperative osteosarcopenia and clinicopathological factors and prognosis was analyzed.

RESULTS

The median overall survival (OS) and disease-free survival (DFS) of patients with osteosarcopenia were significantly shorter than those of patients without osteosarcopenia (OS: 23 and 48 months, respectively, P < 0.001; DFS: 13.4 and 21.2 months, respectively, P = 0.004). On multivariate analysis, osteosarcopenia was found to be an independent factor associated with OS (hazard ratio [HR] 1.98; 95% confidence interval [CI] 1.40-2.80; P < 0.001) and DFS (HR 1.53; 95% CI 1.11-2.10; P = 0.009).

CONCLUSIONS

Preoperative osteosarcopenia may be a useful prognostic factor in patients with PDAC who undergo surgical resection. Further studies are needed to assess whether perioperative, nutritional interventions and rehabilitation contribute to improving the prognosis of these patients.

Osteosarcopenia predicts poor survival in patients with cirrhosis: a retrospective study

BACKGROUND

Osteosarcopenia, defined as the coexistence of sarcopenia and osteoporosis, is associated with adverse clinical outcomes. The present study investigated the prognostic significance of osteosarcopenia in patients with cirrhosis.

METHODS

This retrospective study evaluated 126 patients with cirrhosis. Participants were classified into three groups based on the presence or absence of (1) sarcopenia and/or osteoporosis; and (2) Child-Pugh (CP) class B/C cirrhosis and/or osteosarcopenia, and the cumulative survival rates were compared between the groups. Cox proportional hazards model was used to identify independent factors associated with mortality. Sarcopenia and osteoporosis were diagnosed according to the Japan Society of Hepatology and the World Health Organization criteria, respectively.

RESULTS

Among the 126 patients, 24 (19.0%) had osteosarcopenia. Multivariate analysis identified osteosarcopenia as a significant and independent prognostic factor. The cumulative survival rates were significantly lower in patients with osteosarcopenia than in those without (1/3/5-year survival rates = 95.8%/73.7%/68.0% vs. 100%/93.6%/86.5%, respectively; p = 0.020). Patients with osteosarcopenia, but not sarcopenia or osteoporosis alone, had significantly lower cumulative survival rates than those without both conditions (p = 0.019). Furthermore, patients with both CP class B/C and osteosarcopenia had significantly lower cumulative survival rates than those without both (p < 0.001) and with either condition (p < 0.001).

CONCLUSIONS

Osteosarcopenia was significantly associated with mortality in patients with cirrhosis. The cumulative survival rates were lower in patients with osteosarcopenia than in those without both conditions. Additionally, comorbid osteosarcopenia worsened the prognosis of patients with CP class B/C. Therefore, simultaneous evaluation of both sarcopenia and osteoporosis is crucial to better predict the prognosis.

Osteopenia Is Associated with Shorter Survival in Patients with Intrahepatic Cholangiocarcinoma

BACKGROUND

The prognostic importance of osteopenia in patients with intrahepatic cholangiocarcinoma (ICC) undergoing hepatectomy is unclear. The aim of this study was to evaluate the impact of osteopenia on survival in patients with ICC.

METHODS

A total of 71 patients who underwent hepatectomy at Jichi Medical University between July 2008 and June 2022 were included in this study. Non-contrast computed tomography scan images at the eleventh thoracic vertebra were used to assess bone mineral density. The cutoff value was calculated using a threshold value of 160 Hounsfield units. Overall survival curves were made using the Kaplan-Meier method and the log-rank test was used to evaluate survival. The hazard ratio (HR) and 95% confidence interval (CI) for overall survival were calculated using Cox's proportional hazard model.

RESULTS

In multivariable analysis, osteopenia (HR 3.66, 95%CI 1.16-14.1, p = 0.0258) and the platelet-lymphocyte ratio (HR 6.26, 95%CI 2.27-15.9, p = 0.0008) were significant independent factors associated with overall survival. There were no significant independent prognostic factors for recurrence-free survival.

CONCLUSIONS

Preoperative osteopenia is significantly associated with postoperative survival in patients with ICC undergoing hepatectomy.
