RESUMEN

INTRODUCTION: This study evaluated the performance of the albumin-lymphocyte-globulin-C-reactive protein (CRP) (ALGC) index as a novel prognostic biomarker for hepatocellular carcinoma (HCC) after hepatectomy. METHODS: Patients (n=178) who underwent hepatectomy for HCC (July 2010 - December 2021) were analyzed. The ALGC index was calculated as [(albumin × lymphocyte) / (CRP × globulin × 104)]. Patients were divided into a low ALGC group (<1.82; n=81) and a high ALGC group (≥1.82; n=97). The association of the ALGC index with survival was assessed by univariate and multivariate analyses. RESULTS: The median overall survival (OS) was 100 (range: 1-149) months with 1-, 3-, and 5-year OS rates of 91.6%, 81.2%, and 64.2%, respectively. In univariate analysis, ALGC index (<1.82), alpha-fetoprotein (≥25 ng/mL), tumor size (≥3.5 cm), microvascular invasion, and multiple tumors were associated with shorter OS. ALGC index (<1.82) (hazard ratio [95% confidence interval]) (2.48 [1.407-4.513]; P=0.001) and multiple tumors (1.92 [1.070-3.356]; P=0.029) were independent predictors of OS in multivariate analysis. CONCLUSION: ALGC index is a novel prognostic biomarker for HCC after hepatectomy. It may assist in treatment stratification and better management of patients with HCC.

RESUMEN

BACKGROUND: This study aimed to evaluate the effects of sarcopenia and inflammation on the prognosis of patients with pancreatic cancer after pancreaticoduodenectomy. METHODS: Eighty patients who had undergone pancreaticoduodenectomy for pancreatic cancer between July 2010 and December 2023 were included in this study. The psoas muscle index was used to assess sarcopenia. The C-reactive protein-to-albumin ratio, prognostic nutritional index, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio were used to calculate the preoperative inflammatory marker levels. The prognostic factors for overall survival were determined using Cox regression analysis. RESULTS: Twenty-four patients were diagnosed with sarcopenia. Sarcopenia showed a significant association with advanced tumor stage. Univariate analysis revealed a significant reduction in overall survival in patients with a prognostic nutritional index of <45, C-reactive protein-to-albumin ratio of ≥0.047, cancer antigen 19-9 levels of ≥130 U/mL, sarcopenia, lymph node metastasis, and vascular invasion. Multivariate analysis revealed that a C-reactive protein-to-albumin ratio of ≥0.047 (hazards ratio, 3.383; 95% confidence interval: 1.384-8.689; p< 0.001), cancer antigen 19-9 levels of ≥130 U/mL (hazards ratio, 2.720; 95% confidence interval: 1.291-6.060; p = 0.008), sarcopenia (hazards ratio, 3.256; 95% confidence interval: 1.535-7.072; p = 0.002) and vascular invasion (hazards ratio, 2.092; 95% confidence interval: 1.057-4.170; p = 0.034) were independent predictors of overall survival. Overall survival in the sarcopenia and high C-reactive protein-to-albumin ratio groups was significantly poorer than that in the non-sarcopenia and low C-reactive protein-to-albumin ratio and sarcopenia or high C-reactive protein-to-albumin ratio groups. CONCLUSION: Sarcopenia and a high C-reactive protein-to-albumin ratio are independent prognostic factors in patients with pancreatic cancer after pancreaticoduodenectomy. Thus, sarcopenia may have a better prognostic value when combined with the C-reactive protein-to-albumin ratio.

RESUMEN

Background/Aim: Sarcopenia accompanied by systemic inflammation is associated with poor prognosis in patients with cancer. This study evaluated the prognostic significance of sarcopenia (myopenia and myosteatosis) and systemic inflammatory markers in older patients (aged ≥80 years) with resected biliary tract cancer. Patients and Methods: Patients who underwent resection for biliary tract cancer between July 2010 and January 2023 at the NHO Fukuyama Medical Center were retrospectively reviewed. Preoperative computed tomography measured myopenia and myosteatosis, using the psoas muscle index and modified intramuscular adipose tissue content. Associations between clinicopathological characteristics, inflammation-based prognostic scores, and overall survival were analyzed using Cox proportional hazards models. Results: Univariate analysis revealed low C-reactive protein-to-albumin ratio (<0.125), low prognostic nutritional index (<42), low modified intramuscular adipose tissue content, higher T-stage (T3-4), lymph node metastasis, and postoperative complications associated with worse overall survival in older patients (aged ≥ 80 years) with resected biliary tract cancer (n=48). Multivariate analysis identified low prognostic nutritional index (<42) (p=0.007), low modified intramuscular adipose tissue content (p=0.015), higher T-stage (T3-4) (p<0.001), lymph node metastasis (p=0.001), and postoperative complications (p=0.017) as independent predictors of overall survival. Conclusion: Preoperative myosteatosis and low prognostic nutritional index are independent prognostic factors for overall survival in older patients (aged ≥80 years) with resected biliary tract cancer. These factors may be useful for risk stratification and clinical decision-making. Early interventions, such as nutritional support and physical exercise, may improve outcomes after resection of biliary tract cancer.

RESUMEN

BACKGROUND: Sarcopenia accompanied by systemic inflammation is associated with poor prognosis in patients with advanced hepatocellular carcinoma (HCC). However, the effect of sarcopenia combined with systemic inflammation on the prognosis of patients with advanced HCC who underwent hepatectomy is unclear. This study aimed to evaluate the effect of sarcopenia and inflammation on the prognosis of patients with advanced HCC. METHODS: This retrospective study included 151 patients recruited between July 2010 and December 2022. We defined advanced HCC as that presenting with vascular invasion or tumor size ≥2 cm or multiple tumors. Sarcopenia was assessed using the psoas muscle index. Preoperative inflammatory markers were used by calculating the prognostic nutritional index, albumin-globulin ratio (AGR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio. Cox regression analysis was performed to determine the prognostic factors for overall survival. RESULTS: Of 151 patients, sarcopenia occurred in 84 (55.6 %). Sarcopenia was significantly associated with male sex, older age, body mass index (<25 kg/m2), and a higher NLR. In the multivariate analysis, AGR <1.25 (hazard ratio [HR], 2.504; 95% confidence interval [CI]: 1.325-4.820; p < 0.05); alpha-fetoprotein levels ≥25 ng/mL (HR, 1.891; 95% CI: 1.016-3.480; p = 0.04); and sarcopenia (HR, 1.908; 95% CI: 1.009-3.776; p < 0.05) were independent predictors of overall survival. The sarcopenia and low AGR groups had significantly worse overall survival than either the non-sarcopenia and high AGR or sarcopenia and low AGR groups. CONCLUSION: Sarcopenia and AGR are independent prognostic factors in patients with advanced HCC. Thus, sarcopenia may achieve a better prognostic value when combined with AGR.

RESUMEN

PURPOSE: To evaluate the prognostic significance of sarcopenia and systemic inflammatory markers in patients with surgically resected biliary tract cancer (BTC). METHODS: Between July 2010 and December 2022, 146 patients were recruited. Sarcopenia was assessed using the psoas muscle index. Preoperative inflammatory markers were used to calculate the prognostic nutritional index (PNI), neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio. Cox regression analysis was performed to determine prognostic factors for overall survival (OS) and recurrence-free survival (RFS). P < 0.05 was considered statistically significant. RESULTS: Sixty-four patients had sarcopenia. Sarcopenia was associated with body mass index (< 22 kg/m2), lymph node metastasis, and low PNI (< 42). R1/R2 resection (P = 0.02), sarcopenia (P < 0.001), lymph node metastasis (P = 0.007), intrahepatic cholangiocarcinoma (P < 0.001), and low PNI (P = 0.01) were independent predictors of OS, while male sex (P = 0.04), R1/R2 resection (P < 0.001), lymph node metastasis (P = 0.005), intrahepatic cholangiocarcinoma (P < 0.001), tumor differentiation (other than well; P = 0.003), and low PNI (P = 0.03) were independent predictors of RFS. Patients were stratified into no sarcopenia and high PNI (≥ 42; A), sarcopenia or low PNI (B), and sarcopenia and low PNI (C) groups. Group C had worse OS than the other two groups (P < 0.001 and P = 0.02, respectively). CONCLUSION: Sarcopenia is associated with the PNI. Sarcopenia and the PNI are independent prognostic factors among patients with resected BTC. Sarcopenia may have better prognostic value when combined with the PNI.

RESUMEN

Epithelial-mesenchymal transition (EMT) is a biological process by which epithelial cells acquire mesenchymal characteristics. In malignant tumors, EMT is crucial for acquisition of a mesenchymal phenotype with invasive and metastatic properties, leading to tumor progression. An inflammatory microenvironment is thought to be responsible for the development and progression of colorectal cancer (CRC); however, the precise role of inflammatory microenvironments in EMT-related CRC progression remains unclear. Here, we show the spatiotemporal visualization of CRC cells undergoing EMT using a fluorescence-guided EMT imaging system in which the mesenchymal vimentin promoter drives red fluorescent protein (RFP) expression. An inflammatory microenvironment including TNF-α, IL-1ß, and cytokine-secreting inflammatory macrophages induced RFP expression in association with the EMT phenotype in CRC cells. In vivo experiments further demonstrated the distribution of RFP-positive CRC cells in rectal and metastatic tumors. Our data suggest that the EMT imaging system described here is a powerful tool for monitoring EMT in inflammatory microenvironment-CRC networks.

RESUMEN

The incidence of small bowel lymphoma (SBL) is increasing worldwide. In contrast to resectable SBL, the treatment of unresectable SBL is still contentious. Here, we report a case of unresectable SBL that was treated by laparoscopic exclusion of the affected intestine before systemic chemotherapy was administered. An 84-year-old man was diagnosed with primary SBL involving extranodal dissemination. The patient received prophylactic surgery, namely exclusion of the affected intestine. This therapy diminishes well-known and life-threatening complications, such as perforation, bleeding, and obstruction, which may still occur after chemotherapy, and it makes the administration of chemotherapy safer. In addition, the surgery provides easy access for direct endoscopic observation and biopsy, which are otherwise difficult to perform. Follow-up after two courses of chemotherapy showed that the patient had achieved complete remission. In conclusion, the procedure described here may be an effective strategy for unresectable SBL.

RESUMEN

BACKGROUND: The external jugular vein (EJV) approach for totally implantable venous access devices (TIVADs) is safe. However, the success rate is unsatisfactory because of the difficulty in catheterization due to the acute angle between the EJV and the subclavian vein (SCV). A novel "shrug technique" to overcome this difficulty was developed, and its efficacy was assessed in a consecutive case series. METHODS: TIVAD placement was performed via the EJV cut-down approach. "Shrug technique," a simple way to straighten the EJV-SVC angle by shrugging the patient's shoulder, was applied to facilitate the passage of the guidewire and sheath-introducer when there was acute angulation between the EJV and SCV. RESULTS: A total of 254 patients underwent TIVAD implantation by the EJV cut-down approach. The "shrug technique" was applied in 51 cases (20%), and catheterization was successful in all cases. Thus, TIVAD implantation was successfully completed in all 254 cases (100%) in a single operative setting. The median operating time was 38 [IQR 30-45] min. Eleven complications (4%) were observed, but none of them were EJV-specific. CONCLUSION: The "shrug technique" is simple but very useful to achieve a higher success rate and safer insertion of TIVADs from the EJV. J. Surg.
