RESUMEN
BACKGROUND/AIM: The study aimed to investigate the efficacy of radiotherapy or chemoradiotherapy for isolated locoregional recurrence after pancreatectomy for pancreatic cancer. PATIENTS AND METHODS: Twenty-eight patients who had isolated locoregional recurrence after pancreatectomy for pancreatic cancer between 2007 and 2021 were retrospectively analyzed. We investigated the effect of the treatment method [radiotherapy or chemoradiotherapy (radiotherapy with concurrent chemotherapy)] on progression-free survival (PFS) and post-recurrence survival (PRS). RESULTS: The median disease-free survival was 16.1 months (range=4.7-47.1 months). Five patients received radiotherapy and 21 patients received chemoradiotherapy [radiotherapy concurrent with gemcitabine (GEM) or S-1] for locoregional recurrence. All patients except one patient with interstitial pneumonia were treated with salvage chemotherapy after irradiation. The median PFS rates of the radiotherapy group and the chemoradiotherapy group were 2.8 months (range=1.5-5.4 months) and 16.8 months (range=2.7-42.8 months), respectively. The median PRS rates were 23.7 months (range=8.1-26.4 months) for the radiotherapy group and 26.2 months (range=6.0-64.7 months) for the chemoradiotherapy group. Multivariate analysis identified radiotherapy [hazard ratio (HR)=12.2, 95% confidence interval (CI)=3.29-45.6, p<0.001] and serum DUPAN-2 >150 U/ml (HR=2.90, 95%CI=1.22-6.93, p=0.02) as independent predictors of PFS, and UICC TNM Stage ≥III (HR=3.23, 95%CI=1.17-8.96, p=0.02) and modified Glasgow prognostic score before the treatment for the recurrence 1 or 2 (HR=3.05, 95%CI=1.15-8.08, p=0.03) as independent predictors of PRS. CONCLUSION: Chemoradiotherapy for isolated locoregional recurrence after pancreatectomy for pancreatic cancer could suppress re-recurrence more effectively than radiotherapy.

BACKGROUND/AIM: No studies have investigated the advantage of laparoscopic hepatectomy (LH) compared with open hepatectomy (OH) from a nutritional perspective. This study aimed to compare the postoperative nutritional status between LH and OH. PATIENTS AND METHODS: A total of 186 patients who underwent partial hepatic resection for liver tumors were analyzed retrospectively. We compared perioperative variables between LH and OH. The nutritional status was assessed using serum albumin (Alb) and rapid turnover protein concentrations. We investigated risk factors for postoperative malnutrition using univariate and multivariate analyses. RESULTS: The LH group, compared with the OH group, had a significantly shorter operative time (239 vs. 344 min, p<0.03), less intraoperative blood loss (100 vs. 343 g, p<0.01), and a shorter length of postoperative stay (8 vs. 11 days, p<0.01). Postoperative serum Alb and prealbumin concentrations in the LH group were significantly higher than those in the OH group (3.4 vs. 3.2 g/dl, p<0.01; 15.0 vs. 12.0 mg/dl, p=0.02, respectively). The multivariate analysis showed that OH (p=0.02) and hepatocellular carcinoma (p<0.01) were significant and independent risk factors for postoperative malnutrition. CONCLUSION: LH may be superior to OH in terms of the postoperative nutritional status, intraoperative blood loss, and length of postoperative stay.

Background: This study aimed to identify the prognostic factors after pancreatectomy for borderline resectable pancreatic cancer abutting major arteries (BR-A).Methods: We retrospectively investigated relationship between preoperative and intraoperative variables and overall survival (OS) through univariate and multivariate analyses. The cut-off points of preoperative therapy duration and response rates of serum carbohydrate antigen 19-9 (CA19-9) levels after preoperative therapy were determined through a minimum P-value approach using the log-rank test for OS. Overall survival was compared among patients stratified according to the independent prognostic factors and the presence or absence of pancreatectomy.Results: After pretreatment, 17 patients underwent pancreatectomy and four patients continued chemotherapy without surgery. Multivariate analysis in 17 resected BR-A patients demonstrated decreased serum CA19-9 levels and preoperative therapy duration of ≥4 months were the independent prognostic factors [hazard ratio (HR) 0.01; P = 0.002, HR 0.13; P = 0.02]. Patients who underwent surgery with decreased serum CA19-9 levels after preoperative therapy of ≥4 months had a significantly better prognosis than those without one or both of independent prognostic factors and those who did not undergo surgery (median survival time: not estimated, 23.3 months, 10.5 months, and 10.8 months; P = 0.02, P = 0.004, and P = 0.001, respectively). Furthermore, the prognosis did not significantly differ between the patients who underwent surgery without meeting either one or both criteria and those without surgery.Conclusions: Preoperative therapy duration of ≥4 months and decreased serum CA19-9 levels are independent prognostic factors among BR-A patients.
RESUMEN
BACKGROUND: This study aimed to investigate the effects of changes in clinicopathological factors during preoperative chemotherapy for pancreatic cancer, including skeletal muscle volume, on recurrence and prognosis after pancreatectomy. METHODS: Data from 41 patients who underwent resection for pancreatic cancer after preoperative chemotherapy from 2012 to 2021 were retrospectively reviewed. Skeletal muscle volume was substituted for the psoas muscle area (PMA) at the level of the third lumbar vertebra. We investigated the relationship of clinicopathological factors during preoperative chemotherapy with disease-free survival (DFS) and overall survival (OS). The association between clinicopathological factors and a decrease in PMA was investigated. RESULTS: In the multivariate analyses for DFS and OS, the factors associated with recurrence were as follows: decrease in PMA (P = 0.003) and the absence of adjuvant therapy (P = 0.03), and the factors associated with poor prognosis were as follows: decrease in PMA (P = 0.04) and the absence of adjuvant therapy (P = 0.008), and the resectability of borderline resectable and unresectable-locally advanced tumors (P = 0.033). All patients with partial response according to the Response Evaluation Criteria in Solid Tumors (version 1.1) had no decrease in PMA (P = 0.01). The proportion of patients with Evans classification ≥ II was significantly higher in the group without a decrease in PMA (P = 0.02). The proportion of patients with an average relative dose intensity of adjuvant therapy ≥0.6 was significantly higher in the group without a decrease in PMA (P = 0.02). CONCLUSION: Changes in preoperative skeletal muscle volume during preoperative chemotherapy for pancreatic cancer is a potential predictor of recurrence and prognosis after pancreatectomy.
RESUMEN
PURPOSE: Abdominal aortic calcification (AAC), an indicator of systemic arteriosclerosis, is associated with short- and long-term outcomes in malignancies. We investigated the prognostic impact of AAC in patients who underwent hepatectomy for intrahepatic cholangiocarcinoma (IHCC). METHODS: The study cohort comprised 46 patients who underwent hepatectomy for IHCC between January 2008 and September 2020. The AAC volume measured by preoperative computed tomography was used to construct a model of the calcified segment from the renal artery to the common iliac artery bifurcation. We investigated the relationship between AAC and the long-term outcomes. The AAC volume cutoff value was calculated from a receiver-operating characteristic curve based on the three-year survival. RESULTS: According to our cutoff AAC volume of 3,700 mm3, 11 patients (24%) had high AAC volumes. The high-AAC group was significantly older than the low-AAC group (73 vs. 62 years old, p < 0.01). A multivariate analysis of the cancer-specific survival showed that a high serum carbohydrate antigen 19-9 concentration (hazard ratio [HR] 5.57, p = 0.01), high AAC volume (HR 3.03, p = 0.04), and [high?] T3 or T4 levels (HR 9.05, p < 0.01) were independently associated with a poor prognosis. CONCLUSION: AAC is a useful predictor of the oncological prognosis in patients undergoing hepatectomy for IHCC.
RESUMEN
PURPOSE: Atherosclerosis and cancer may progress through common pathological factors. This study was performed to investigate the association between the abdominal aortic calcification (AAC) volume and outcomes following surgical treatment for pancreatic cancer. METHODS: The subjects of this retrospective study were 194 patients who underwent pancreatic cancer surgery between 2007 and 2020. The AAC volume was assessed through routine preoperative computed tomography. Univariate and multivariate analyses were performed to evaluate the impact of the AAC volume on oncological outcomes. RESULTS: A higher AAC volume (≥ 312 mm3) was identified in 66 (34%) patients, who were significantly older and had a higher prevalence of diabetes and sarcopenia. Univariate analysis revealed several risk factors for overall survival (OS), including male sex, an AAC volume ≥ 312 mm3, elevated carbohydrate antigen 19-9, prolonged operation time, increased intraoperative bleeding, lymph node metastasis, poor differentiation, and absence of adjuvant chemotherapy. Multivariate analysis identified an AAC volume ≥ 312 mm3, prolonged operation time, lymph node metastasis, poor differentiation, and absence of adjuvant chemotherapy as independent OS risk factors. The OS rate was significantly lower in the high AAC group than in the low AAC group. CONCLUSION: The AAC volume may serve as a preoperative prognostic indicator for patients with pancreatic cancer.
RESUMEN
BACKGROUND: Mature cystic teratomas or dermoid cysts of the pancreas complicate surgical approaches because of their anatomical position and ever-growing size. Herein, we report a case of a giant mature cystic teratoma of the pancreas that was successfully resected via complete laparoscopic distal pancreatectomy (LDP). CASE PRESENTATION: A 39-year-old female patient was referred to our hospital for the evaluation of a pancreatic tumor. Three years of follow-up revealed that the tumor had increased in size to 18 cm, with hyperintense solid components on diffusion-weighted magnetic resonance imaging. Considering the possibility of malignancy, we decided to perform an LDP. The capsule appeared solid enough to withstand the retraction of the endoscopic forceps. Tumor size made it difficult to dissect the dorsal side of the tumor from the caudal to the cranial side. Early transection of the pancreas and additional ports facilitated dissection of the dorsal side of the tumor. We completed the LDP without intraoperative cyst rupture. On pathological examination, the tumor was diagnosed as a mature cystic teratoma originating from the pancreatic tail. The patient was discharged on postoperative day 13 with no complications. CONCLUSION: LDP may be an option for surgical procedures in patients with large cystic lesions of the pancreatic body or tail. Intraoperative observation of the tumor and surgical refinement are necessary to complete the laparoscopic procedure without tumor rupture.
RESUMEN
BACKGROUND/AIM: Laparoscopic hepatic resection is currently used for ruptured hepatocellular carcinoma (HCC); however, it is technically challenging. We developed and implemented surgical strategies for emergency laparoscopic partial liver resection in selected patients with peripheral lesions who were hemodynamically stable and without severe liver dysfunction. PATIENTS AND METHODS: The surgical techniques used were as follows. First, the Pringle maneuver was performed to control hepatic blood inflow (step 1). Next, strong hemostatic agents were applied at the rupture point of the tumor (step 2). The hanging tape was positioned along the dorsal side of the resection line to control the partial blood inflow and outflow of the tumor, as well as to expose the surgical plane (step 3). The liver parenchyma was dissected along the hanging tape (step 4). We performed emergency laparoscopic partial liver resection in three patients who were in a pre-shock status. RESULTS: The tumors were located in segments 6 (cases 1 and 2) and 2 (case 3). The tumor diameters were 90, 62, and 80 mm. The Preoperative Child-Pugh scores were B7, B9, and B8. The hemostatic products performed well and controlled bleeding from the ruptured HCC. The hanging tape facilitated the dissection of the liver parenchyma. The operative time and intraoperative blood loss were 135 min and 400 ml, 266 min and 200 ml, and 191 min and 495 ml for cases 1, 2, and 3 respectively. There were no in-hospital deaths. CONCLUSION: Emergency laparoscopic partial liver resection could be an option for patients with ruptured HCC.

PURPOSE: Simultaneous dual hepatic vein embolization (DHVE) has been proposed for safe right-sided hepatectomy, with good results for liver hypertrophy and function. However, the histological and radiological findings of DHVE have not been thoroughly investigated. METHODS: This study included 14 patients who underwent DHVE before right-sided major hepatectomy. DHVE was performed if the future liver remnant was < 35% or borderline, but with concomitant vascular resection. The liver function was assessed using the signal intensity on Gd-EOB-DTPA-MRI. A histological evaluation of the area of DHVE and portal vein embolization (PVE) were performed. RESULTS: The median pre- and post-functional liver remnants were 363 ml and 498 ml, respectively (p < 0.001). The median growth rate was 48.6%, and there was no post-hepatectomy liver failure in the patients who underwent DHVE. The signal intensity ratio in the area of DHVE was lower than that in the areas of PVE and the remnant liver (p < 0.01). The degree of congestion and necrosis was greater in the area of DHVE than in the area of PVE alone (p < 0.01 and p = 0.04, respectively). CONCLUSIONS: We observed good liver hypertrophy after DHVE and histological and radiological changes in the area of DHVE. Our findings provide a compelling rationale for further investigation of the mechanism of liver hypertrophy in DHVE.
RESUMEN
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.

Background/Aim: This study aimed to investigate the relationship between prechemotherapy blood eicosapentaenoic acid (EPA) levels, sarcopenia, and overall survival in patients with pancreatic and biliary tract cancer undergoing chemotherapy. Patients and Methods: Forty-five patients with recurrent, non-resected pancreatic or biliary tract cancer undergoing chemotherapy were retrospectively analyzed. The skeletal muscle mass was measured at the third lumbar vertebra. Sarcopenia cut-off values were based on the Japanese Society of Hepatology sarcopenia assessment criteria. Two months after starting chemotherapy, the patients received enteral nutrition containing omega-3 fatty acids. Results: Patients with pancreatic and biliary tract cancers with low pre-treatment blood EPA levels had significantly more intense sarcopenia than those with high EPA levels (p=0.023). Patients with sarcopenia before chemotherapy had significantly lower overall survival than those without sarcopenia. Multivariate analysis revealed blood EPA concentration as an independent prognostic factor (p<0.01). Lumbar muscle volume, a marker of sarcopenia, showed a clear positive correlation with prechemotherapy EPA concentration (p=0.008). In patients administered with enteral nutrition containing omega-3 fatty acids, both EPA concentration and lumbar muscle volume were significantly higher than those prior to intervention, indicating sarcopenia improvement due to the intervention. Conclusion: In patients with recurrent non-resected pancreatic and biliary tract cancer, low blood EPA levels before chemotherapy are associated with sarcopenia and poor prognosis.
RESUMEN
BACKGROUND/AIM: This study aimed to identify the risk factors for early recurrence (ER) after pancreatic ductal adenocarcinoma (PDAC) resection to create a novel scoring system for ER and analyze their effect on the recurrence pattern. PATIENTS AND METHODS: Sixty patients with PDAC who underwent pancreatectomy were included. The predicted risk factors for ER were analyzed. A new score defining ER was created and analyzed for recurrence pattern and prognosis. RESULTS: Independent predictors included high CA 19-9 (≥147 U/ml), high lymph node ratio (LNR of ≥0.1277), and no adjuvant chemotherapy (AC). The 5-year overall survival rates with a score of 0, 1, and 2 were 55.8%, 11.0%, and 0%, respectively. In the moderate- risk score group, prognosis was improved by induction of AC within 58 days. CONCLUSION: Preoperative high CA19-9, high LNR, and no AC could be ER predictors. Induction of postoperative chemotherapy within 58 days may improve prognosis.

AIM: To study the effect of preoperative osteosarcopenia (OSP) on the prognosis of treatment (surgery or radiofrequency ablation (RFA)) in patients with Barcelona Cancer Liver Classification stage A hepatocellular carcinoma (BCLC A HCC). METHODS: This study enrolled 102 patients with BCLC A HCC who underwent surgical resection (n = 45) and RFA (n = 57); the patients were divided into two groups: OSP (n = 33) and non-OSP (n = 69). Overall survival (OS) and disease-free survival (DFS) curves for both the groups and treatment methods (surgery and RFA) were generated using the Kaplan-Meier method and compared using the log-rank test. Univariate analyses for OS and DFS were performed using log-rank test. Multivariate analyses were performed for factors that were significant at univariate analysis by Cox proportional hazard model. RESULTS: Multivariate analysis showed that OSP (HR 2.44; 95 % CI 1.30-4.55; p < 0.01) and treatment (HR 0.57; 95 % CI 0.31-0.99; p = 0.05) were significant independent predictors of DFS; and treatment (HR, 0.30; 95 % CI 0.10-0.85; p = 0.03) was a significant independent predictor of OS in the non-OSP group, in which the OS rate was significantly lower in patients treated with RFA than in those treated by resection (p = 0.01). CONCLUSIONS: OSP is a prognostic factor for BCLC A HCC treatment. Surgical approach was associated with a significantly better prognosis in patients without OSP compared to those who underwent RFA.

OBJECTIVES: Signal intensity ratio of pancreas to spleen (SI ratio p/s ) on fat-suppressed T1-weighted images of magnetic resonance imaging has been associated with pancreatic exocrine function. We here investigated the predictive value of the SI ratio p/s for the development of nonalcoholic fatty liver disease (NAFLD) after pancreaticoduodenectomy (PD). MATERIALS AND METHODS: This study comprised 208 patients who underwent PD. NAFLD was defined as a liver-to-spleen attenuation ratio of <0.9 calculated by a computed tomography 1 year after surgery. SI ratio p/s was calculated by dividing the average pancreas SI by the spleen SI. We retrospectively investigated the association of clinical variables including the SI ratio p/s and NAFLD by univariate and multivariate analyses. RESULTS: NAFLD after 1 year was developed in 27 patients (13%). In multivariate analysis, the SI ratio p/s < 1 ( P < 0.001) was an independent predictor of incidence of NAFLD. The SI ratio p/s < 1 was associated with low amylase level of the pancreatic juice ( P < 0.001) and progressed pancreatic fibrosis ( P = 0.017). According to the receiver operating characteristics curve, the SI ratio p/s had better prognostic ability of NAFLD than the remnant pancreas volume. CONCLUSIONS: The SI ratio p/s is useful to predict NAFLD development after PD. Moreover, the SI ratio p/s can be a surrogate marker, which represents exocrine function of the pancreas.

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.

Background: Systemic inflammatory response represented by C-reactive protein and albumin ratio (CAR) and modified albumin-bilirubin (mALBI) grade both have been associated with long-term outcome in patients with hepatocellular carcinoma (HCC). In this study, we investigated the prognostic utility of combined score of CAR and mALBI score to predict the prognosis of HCC patients after hepatic resection. Methods: This study included 214 patients who had undergone primary hepatic resection for HCC between 2008 and 2018. Systemic inflammatory response and mALBI were evaluated preoperatively and patients were classified into three groups based on the combination of CAR and mALBI score: low CAR and low mALBI grade (score 0), either high CAR or high mALBI grade (score 1), and both high CAR and high mALBI grade ≥2b (score 2). Multivariate Cox proportional hazard models were conducted to assess disease-free and overall survival. Results: In multivariate analysis, sex (p < 0.01), HBsAg positivity (p < 0.01), serum AFP level ≥20 ng/mL (p < 0.01), microvascular invasion (p = 0.02), multiple tumors (p < 0.01), type of resection (p < 0.01), and CAR-mALBI score ≥2 (HR 2.19, 95% CI 1.39-3.44, p < 0.01) were independent prognostic factors of disease-free survival, while sex (p = 0.01), HBsAg positivity (p < 0.01), poor tumor differentiation (p = 0.03), multiple tumors (p < 0.01), CAR-mALBI score ≥2 (HR 2.70, 95% CI 1.51-4.83, p < 0.01) were independent prognostic factors of overall survival. Conclusions: CAR-mALBI score is associated with disease-free and overall survival in patients with HCC after hepatic resection, suggesting the importance of evaluating both hepatic functional reserve and host-inflammatory state in the risk assessment of HCC patients.
RESUMEN
AIM: Pancreatic ductal adenocarcinoma treatment is mainly based on the anatomical resectability classification. However, prognosis-based classification may be more reasonable. In this study, we stratified resectable pancreatic ductal adenocarcinoma according to preoperative factors and reconsidered treatment strategies. METHODS: We retrospectively evaluated 131 patients who underwent upfront surgery for resectable pancreatic ductal adenocarcinoma between 2007 and 2019. Recurrence within 1 year after surgery was defined as early recurrence, and the risk factors for early recurrence were identified using preoperative factors. Subsequently, we calculated the scores and stratified the participant groups. RESULTS: Fifty-five (42 %) patients who relapsed within 1 year showed significantly poorer survival than those without recurrence (median overall survival, 14.0 vs. 80.6 months; p < 0.01). Multivariate analysis revealed that a tumor diameter of ≥24 mm (p < 0.01) and preoperative serum carbohydrate antigen 19-9 level of ≥380 U/mL (p = 0.04) were the independent risk factors for early recurrence. Early recurrence score was created using these factors, stratifying the participant group into three groups of 0-2 points, and the prognosis was significantly different (median overall survival, 49.3 vs. 31.2 vs. 16.0 months; p < 0.01). CONCLUSION: We stratified the upfront surgical cases of resectable pancreatic ductal adenocarcinoma. The group with a score of 0 had a good prognosis, and upfront surgery was possibly not futile on patients in poor general condition. The group with a score of 2 had a poor prognosis and may require stronger preoperative treatment.

OBJECTIVE: The prognostic impact of occult vertebral fracture (OVF) in patients with malignancies is a new cutting edge in cancer research. This study was performed to analyze the prognostic impact of OVF after surgery for pancreatic cancer. METHODS: This study involved 200 patients who underwent surgical treatment of pancreatic ductal adenocarcinoma. OVF was diagnosed by quantitative measurement using preoperative sagittal computed tomography image reconstruction from the 11th thoracic vertebra to the 5th lumbar vertebra. RESULTS: OVF was diagnosed in 65 (32.5 %) patients. The multivariate analyses showed that male sex (p = 0.01), osteopenia (p < 0.01), OVF (p < 0.01), a carbohydrate antigen 19-9 level of ≥400 U/mL (p < 0.01), advanced stage of cancer (p < 0.01), and non-adjuvant chemotherapy (p = 0.02) were independent risk factors for overall survival. An age of ≥74 years (p < 0.01) and obstructive jaundice (p = 0.03) were independent risk factors for OVF. Furthermore, the combination of OVF and osteopenia further worsened disease-free survival and overall survival compared with osteopenia or OVF alone (p < 0.01; respectively). CONCLUSION: Evaluation of preoperative OVF might be a useful prognostic indicator for patients with pancreatic ductal adenocarcinoma.

PURPOSE: This study examined the impact of osteosarcopenia on recurrence and the prognosis after resection for extrahepatic biliary tract cancer (EBTC). METHODS: We retrospectively analyzed 138 patients after resection for perihilar cholangiocarcinoma (11), distal cholangiocarcinoma (54), gallbladder carcinoma (30), or ampullary carcinoma (43). Osteosarcopenia is defined as the concomitant occurrence of osteopenia and sarcopenia. We investigated the relationship between osteosarcopenia and the overall survival (OS) and disease-free survival (DFS) in univariate and multivariate analyses. RESULTS: Osteosarcopenia was identified in 38 patients (27.5%) before propensity score (PS) matching. In the multivariate analysis, the independent recurrence factors were the prognostic nutrition index (p = 0.015), osteosarcopenia (p < 0.001), poorly differentiated adenocarcinoma (p = 0.004), perineural invasion (p = 0.002), and non-curability (p = 0.008), whereas the independent prognostic factors were prognostic nutrition index (p = 0.030), osteosarcopenia (p < 0.001), poorly differentiated adenocarcinoma (p = 0.007), lymphatic invasion (p = 0.018), and non-curability (p = 0.004). After PS matching, there was no significant difference in the variables between the patients with and without osteosarcopenia (n = 34 each). The 5-year DFS and OS after PS matching in patients with osteosarcopenia were significantly worse than in patients without osteosarcopenia (17.6% vs. 38.8%, p = 0.013 and 20.6% vs. 57.4%, p = 0.0005, respectively). CONCLUSIONS: Preoperative osteosarcopenia could predict the DFS and OS of patients after resection for EBTC.

BACKGROUND: The gastrohepatic ligament approach is a form of robot-assisted spleen-preserving distal pancreatectomy (SPDP).1,2 This approach does not require omentum transection, peri-splenic dissection, or stomach traction. METHODS: Considering the advantages of preserving collateral pathways around the spleen, the authors performed the gastrohepatic ligament approach in laparoscopic SPDP while preserving splenic vessels (LSPDP), with specific modifications for laparoscopic surgery. The following surgical technique was performed. First, the gastrohepatic ligament was divided extensively, and all subsequent procedures were performed through the gastrohepatic ligament route. The superior and inferior borders of the pancreas then were dissected to encircle the common hepatic and splenic arteries with vessel loops and to expose the superior mesenteric vein (SMV) and portal vein. After taping of the pancreas on the SMV, the pancreas was divided using a linear stapler. Next, the pancreas was dissected from proximal to distal with preservation of the splenic vessels. Re-taping and traction of the splenic vessels and pancreas could facilitate the dissection of the pancreas body, especially at the splenic hilum. The appropriate counter traction using traction tapes allowed efficient laparoscopic procedures. The LSPDP was performed for three patients, including one obese patient (body mass index, 36 kg/m2) and two patients with an anomalous left hepatic artery branching from the left gastric artery. RESULTS: The mean operation time was 186 min, and the intraoperative blood loss was 37 mL. CONCLUSION: The gastrohepatic ligament approach could be an option for performing LSPDP with the counter traction technique for low-grade malignant tumors.
