ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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.

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.

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.

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.

PURPOSE: The preoperative platelet-to-lymphocyte ratio (PLR) has been reported as an important prognostic index for pancreatic ductal adenocarcinoma (PDAC); however, the significance of the postoperative (post-op) PLR for this disease has not been elucidated. METHODS: We analyzed data on 118 patients who underwent pancreaticoduodenectomy for pancreatic head PDAC, collected from a prospectively maintained database. The post-op PLR was obtained by dividing the platelet count after surgery by the lymphocyte count on post-op day (POD) 14. The patients were divided into two groups according to a post-op PLR of < 310 or ≥ 310. Survival data were analyzed. RESULTS: A high post-op PLR was identified as a significant prognostic index on univariate analysis for disease-free survival (DFS) and overall survival (OS). The post-op PLR remained significant, along with tumor differentiation and adjuvant chemotherapy, on multivariate analysis for OS (hazard ratio = 2.077, 95% confidence interval: 1.220-3.537; p = 0.007). The post-op PLR was a significant independent prognostic index for poor DFS, along with tumor differentiation and lymphatic invasion, on multivariate analysis (hazard ratio = 1.678, 95% confidence interval: 1.056-2.667; p = 0.028). CONCLUSIONS: The post-op PLR in patients with pancreatic head PDAC was an independent predictor of DFS and OS after elective resection.

Background/Aim: Surgical resection is recommended for nonfunctional pancreatic neuroendocrine neoplasms (NF-pNENs). However, metastasis is rare in patients with small lesions with histological grade 1 (G1); thus, observation is an optional treatment approach for small NF-pNENs. Texture analysis (TA) is an imaging analysis mode for quantification of heterogeneity by extracting quantitative parameters from images. We retrospectively evaluated the utility of TA in predicting histological grade of resected NF-pNENs in a multicenter retrospective study. Patients and Methods: The utility of TA in preoperative prediction of grade were evaluated with 29 patients treated by pancreatectomy for NF-pNEN who underwent preoperative dynamic computed tomography scan between January 1, 2013 and December 31, 2020 at three hospitals affiliated with the Jikei University School of Medicine. TA was performed with dedicated software for medical imaging processing for determining histological tumor grade using dynamic computed tomography images. Results: Histological tumor grades based on the 2017 World Health Organization Classification for Pancreatic Neuroendocrine Neoplasms were grade 1, 2 and 3 in 18, 10 and one patient, respectively. Preoperative grades by TA were 1 and 2/3 in 15 and 14 patients, respectively. The sensitivity, specificity and area under the curve for TA-oriented grade 1 lesions were 1.00, 0.889 and 0.965 (95% confidence interval=0.901-1.000), respectively. Conclusion: TA is useful for predicting grade 2/3 NF-pNEN and can provide a safe option for observation for patients with small grade 1 lesions.
ABSTRACT
BACKGROUND: Pancreatic cancer in contact with the superior mesenteric vein/portal vein is classified as resectable pancreatic cancer; however, the biological malignancy and treatment strategy have not been clarified. METHODS: Data from 186 patients who underwent pancreatectomy for pancreatic cancer were evaluated using a prospectively maintained database. The patients were classified as having resectable tumors without superior mesenteric vein/portal vein contact and with superior mesenteric vein/portal vein contact of ≤180°. Disease-free survival, overall survival, and prognostic factors were analyzed. RESULTS: In the univariate analysis, superior mesenteric vein/portal vein contact in resectable pancreatic cancer was a significant prognostic index for disease-free survival and overall survival. In the multivariate analysis for poor disease-free survival, the superior mesenteric vein/portal vein contact remained significant (hazard ratio = 2.13, 95% confidence interval: 1.29-3.51; p < 0.01). In the multivariate analysis, superior mesenteric vein/portal vein contact was a significant independent prognostic index for overall survival (hazard ratio = 2.17, 95% confidence interval: 1.27-3.70; p < 0.01), along with sex, tumor differentiation, nodal involvement, and adjuvant chemotherapy. Portal vein resection for superior mesenteric vein/portal vein contact did not improve the overall survival (p = 0.86). CONCLUSIONS: Superior mesenteric vein/portal vein contact in resectable pancreatic cancer was found to be an independent predictor of disease-free survival and overall survival after elective resection. Thus, pancreatic cancer in contact with the superior mesenteric vein/portal vein may be considered as borderline resectable pancreatic cancer.

BACKGROUND/AIM: This study aimed to identify the optimal duration of pretreatment for unresectable locally advanced (UR-LA) pancreatic cancer and analyze its effect on the prognosis. PATIENTS AND METHODS: This retrospective study included 39 patients with UR-LA pancreatic cancer after pancreatectomy. The cutoff period of preoperative therapy was determined using a receiver operating characteristic curve. We investigated the relationship between preoperative and intraoperative clinical variables and overall survival (OS) in univariate and multivariate analyses. The relationship between the preoperative therapy duration and the clinicopathological variables was investigated. OS was compared according to preoperative therapy duration and the presence or absence of adjuvant surgery. RESULTS: After pretreatment, 15 patients underwent adjuvant surgery and 24 patients continued on chemotherapy without surgery. The multivariate analysis demonstrated preoperative therapy duration ≥6 months was an independent prognostic factor [hazard ratio (HR)=0.10, p=0.04]. No significant difference in the clinicopathological variables was observed between the two groups according to preoperative therapy duration. The OS was significantly better in patients who underwent adjuvant surgery after preoperative therapy duration ≥6 months than in those after preoperative therapy duration <6 months and in those without adjuvant surgery (5-year OS rates: 80% vs. 0%; p=0.01 and 5-year OS rates: 80% vs. 0%; p=0.004, respectively). The OS was not significantly better in patients with adjuvant surgery after preoperative therapy duration <6 months than in those without adjuvant surgery (2-year OS rates: 45.7% vs. 38.1%; p=0.98). CONCLUSION: Preoperative therapy for UR-LA pancreatic cancer for ≥6 months is necessary to improve prognosis after adjuvant surgery.

BACKGROUND: Although primary biliary cholangitis (PBC) is considered a good indication for living-donor liver transplantation (LDLT), the postoperative results are not well known. METHODS: At Jikei University Hospital, 14 patients with PBC underwent LDLT from February 2007 to June 2022. We consider PBC with a Model for End-Stage Liver Disease (MELD) score of <20 to indicate LDLT. We performed a retrospective analysis of the patients' clinical records. RESULTS: The patients' median age was 53 years, and 12 of the 14 patients were female. A right graft was used in 5 patients, and 3 ABO-incompatible transplants were performed. The living donors were children in 6 cases, partners in 4 cases, and siblings in 4 cases. The preoperative MELD scores ranged from 11 to 19 (median, 15). The graft-to-recipient weight ratio ranged from 0.8 to 1.1 (median, 1.0). The median operative time for donors and recipients was 481 and 712 minutes, respectively. The median operative blood loss of donors and recipients was 173 and 1,800 mL, respectively. The median postoperative hospital stay of donors and recipients was 10 and 28 days, respectively. All recipients recovered satisfactorily and remained well during a median follow-up of 7.3 years. Three patients underwent a liver biopsy after LDLT because of acute cellular rejection without histologic findings of PBC recurrence. CONCLUSIONS: Living-donor liver transplantation provides satisfactory long-term survival for patients with PBC with a graft-to-recipient weight ratio of >0.7 and MELD score of <20 without hepatocellular damage and only portal vein hypertension.

BACKGROUND: Previous studies have reported that laparoscopic distal pancreatectomy (LDP) has an advantage in reducing blood loss over open distal pancreatectomy (ODP). This study was performed to investigate whether blood loss is truly reduced in LDP. METHODS: A total of 113 patients undergoing DP from 2014 to 2022 were classified into Open and LDP groups and compared by statistical analysis. Estimated blood loss (EBL) was calculated from the perioperative changes in the hematocrit, hemoglobin, or red blood cell volume, and actual blood loss (ABL) was taken from the operative record. RESULTS: ABL was significantly lower in the LDP than ODP group (50[5-1350] vs 335 [5-1950] ml, P < .01). However, there were no significant differences in EBL calculated from the hematocrit (406 [66-1990] vs 540 [23-1490] ml, P = .14), hemoglobin, or red blood cell volume. EBL showed more linear correlations with ABL in the ODP group (r = 0.64-0.73) than in the LDP group (r = 0.52-0.57). In the multivariate analysis for ABL, ODP (P = .02) and operative time (P < .01) were significant factors. In contrast, no significant factors were found for EBL. CONCLUSIONS: Intraoperative blood loss may be underestimated in LDP, and a new evaluation method needs to be established.

BACKGROUND: The influence of fine needle aspiration (FNA) on peritoneal lavage cytology (CY) in pancreatic ductal adenocarcinoma (PDAC) is unknown. METHODS: We retrospectively analyzed 29 patients with resectable left-sided PDAC undergoing FNA prior to CY examination. We assessed clinical factors related to CY+, scored the tumor diameter (<20 mm = 0, ≥20 mm = 1) and examination interval between FNA and CY (>18 days = 0, ≤18 days = 1), and investigated the probability of CY + by the sum of each score (0-2). RESULTS: The probability of CY+ was 31%. The CY + group had larger tumors and shorter examination intervals than the CY- group. The CY + probability was 75%, 15%, and 13% for a score of 2, 1, and 0, respectively (P = 0.011). CONCLUSION: A short interval between FNA and CY examination for a large tumor may be a risk factor for CY+ in patients with left-sided PDAC.

BACKGROUND/AIM: Evidence on the optimal extent of lymph node dissection for left-sided pancreatic ductal adenocarcinoma (PDAC) is scarce. The aim of the current study was to compare the long-term outcomes of patients who underwent D1 distal pancreatectomy (DP) with D2 DP for left-sided PDAC. PATIENTS AND METHODS: Patients undergoing DP for left-sided PDAC at the four institutions affiliated to The Jikei University were enrolled in this study. Patients were divided into D1 and D2 groups. Patients' clinical characteristics, overall survival (OS), and relapse-free survival (RFS) were compared between the two groups before and after propensity-score matched (PSM) analysis. RESULTS: Of 145 patients with left-sided PDAC, 55 patients underwent D1 DP and 90 underwent D2 DP, of whom 38 matched pairs were included in the PSM analytic cohort. In the unmatched cohort, no significant difference was found between the D1 and D2 groups for both OS (median 2.51 vs. 3.07 years; p=0.709) and RFS (median 1.47 vs. 1.27 years; p=0.565). After PSM, OS (median 2.37 vs. 3.56 years; p=0.407) and RFS (median 1.35 vs. 1.11 years; p=0.542) were not significantly different between the two groups. In a comparison of regional and systemic recurrence sites, no significant difference was observed between the two groups (p=0.500). CONCLUSION: The long-term survival of D1 DP for left-sided PDAC was not inferior to D2 DP. In an era in which the importance of multidisciplinary treatment for PDAC has been documented, unnecessary extended surgery should be avoided.

Horiuchi and colleagues assessed the benefits of adding the Pringle maneuver to laparoscopic cholecystectomy for acute cholecystitis. Compared with laparoscopic cholecystectomy without the Pringle maneuver, including it reduced intraoperative bleeding. Laparoscopic cholecystectomy with the Pringle maneuver is a safe and feasible option that avoids conversion to open laparotomy and prevents serious complications.

BACKGROUND: Cancer cachexia has been associated with unfavorable outcomes in several malignancies. The cachexia index (CXI), which consists of skeletal muscle, inflammation, and nutritional status, has been proposed as a novel biomarker of cachexia. Therefore, we here investigated prognostic value of the CXI in patients with hepatocellular carcinoma (HCC) after hepatic resection. METHODS: The study comprised 213 patients who had undergone primary hepatic resection for HCC between 2008 and 2018. First, the skeletal muscle index (SMI) was calculated as the area of the psoas muscle at the third lumbar vertebra/(the height)2. The CXI was then calculated by the following formula: SMI x serum albumin level/neutrophil-to-lymphocyte ratio (NLR). We retrospectively investigated the relationship between the CXI and disease-free survival as well as overall survival. RESULTS: In multivariate analyses, female (p < 0.01), hepatitis B surface antigen-positivity (p < 0.01), preoperative serum alpha-fetoprotein level ≥20 ng/mL (p = 0.01), preoperative serum protein induced by vitamin K absence or antagonist-II level ≥200 mAU/mL (p = 0.02), multiple tumors (p < 0.01), macrovascular invasion (p = 0.04), type of resection (p < 0.01), and low CXI (p = 0.03) were significant predictors of disease-free survival, while Child-Pugh grade B (p < 0.01), poor tumor differentiation (p = 0.05), multiple tumors (p = 0.01), macrovascular invasion (p = 0.04), NLR (p = 0.04), and low CXI (p < 0.01) were significant predictors of overall survival. In the subgroup analysis of advanced T stage, the CXI was associated with both disease-free (p < 0.01) and overall survival (p = 0.06). CONCLUSIONS: The CXI can be a prognostic indicator in patients with HCC after hepatic resection, suggesting the importance of comprehensive biomarker which includes skeletal muscle, inflammation, and nutritional status.

Background: To study exocrine function of the remnant pancreas after pancreatoduodenectomy (PD), we propose the use of an exocrine index (PEI) that combines the volume of the remnant pancreas and the intraoperative amylase activity of the pancreatic juice. Here, we aimed to determine whether the PEI can predict non-alcoholic fatty liver disease (NAFLD) following PD. Methods: Fifty-seven patients for whom pancreatic juice amylase activity was measured during PD were enrolled. NAFLD was defined as a liver-to-spleen attenuation ratio of <0.9 on plain CT 1 year following surgery. We retrospectively evaluated clinical parameters, including the PEI, to identify predictors of NAFLD. Results: Fifty-four patients (95%) were regularly administered 1200 mg of pancreatic lipase. NAFLD was diagnosed in 13 participants (23%) 1 year following surgery. NAFLD was associated with pancreatic ductal adenocarcinoma (P = .006), soft pancreas (P = .001), small main pancreatic duct (P = 0008), low remnant pancreatic volume (P < .001), low intraoperative amylase activity in the pancreatic juice (P = .001), high pancreatic fibrosis (P = .032), and large body weight loss (P = .015). The PEI was significantly lower in the participants with NAFLD than in those without (P < .001). The participants were then classified into tertiles of PEI: <5 × 106, 5-25 × 106, and >25 × 106. The prevalence of NAFLD in these groups was 53% (10/19), 11% (2/19), and 5% (1/19), respectively. In multivariable analyses, there was a significant association between NAFLD and the PEI (P value for trend = .042). Conclusion: The PEI, calculated using the remnant pancreatic volume and the intraoperative pancreatic juice amylase activity, predicts NAFLD development following PD.
ABSTRACT
BACKGROUND: Adjuvant chemotherapy is recommended for patients with pancreatic cancer after curative resection. However, there is limited evidence regarding the efficacy and prognostic factors for adjuvant chemotherapy in patients with stage I pancreatic cancer. This study aimed to identify patients in whom chemotherapy was effective and to detect prognostic factors for stage I pancreatic cancer based on guidelines of the 8th edition of the Union for International Cancer Control (UICC). METHODS: Between 2009 and 2017, 108 patients diagnosed with stage I pancreatic cancer were enrolled in this study. They were distributed into invasion (n = 68) and non-invasion (n = 40) groups. The relationship between clinicopathological variables, including various prognostic factors, disease-free survival (DFS), and overall survival (OS), were investigated by univariate and multivariate analyses. RESULTS: Five-year survival in all patients with stage I pancreatic cancer was 38.9%. Adjuvant chemotherapy failed to improve DFS or OS in patients with stage I cancer (DFS, p = 0.26; OS, p = 0.30). In subgroup analysis, adjuvant chemotherapy significantly improved DFS (multivariate-adjusted hazard ratio (HR), 0.40; 95% confidence interval [CI], 0.21-0.78; p = 0.007) and OS (multivariate-adjusted HR, 0.32; 95% CI, 0.15-0.68; p = 0.003) in the invasion group than in non-invasion group. In contrast, in the non-invasion group, adjuvant chemotherapy failed to improve DFS and OS in univariate analysis (DFS, p = 0.992; OS, p = 0.808). CONCLUSION: For stage I pancreatic cancer, based on guidelines of the UICC 8th edition, adjuvant chemotherapy may benefit patients with extrapancreatic invasion.

PURPOSE: To assess the efficacy of combination chemotherapy with nafamostat mesilate, gemcitabine and S-1 for unresectable pancreatic cancer patients. MATERIALS AND METHODS: The study was conducted as a single-arm, single center, institutional review board-approved phase II trial. Patients received nafamosntat mesilate (4.8 mg/kg continuous transregional arterial infusion) with gemcitabine (1000 mg/m2 transvenous) on days 1 and15, and with oral S-1 [(80 mg/day (BSA<1.25 m2), 100 mg/day (1.25 ≤ BSA<1.5 m2), or 120 mg/day (BSA ≥1.5 m2)] on days 1-14 or, days 1-7 and 15-21. This regimen was repeated at 28-day intervals. RESULTS: Forty-seven evaluable patients (Male/Female: 31/16, Age (median): 66 (range 35-78) yrs, Stage III/IV 10/37.) were candidates in this study. Two patients in stage III (20%) could undergo conversion surgery. Twenty-four patients (51%) underwent subsequent treatment (1st line/ 2nd line / 4th line, 13/ 10/ 1, FOLFIRINOX: 12, GEM/nab-PTX: 18, TAS-118: 3, chemoradiation with S-1: 2, GEM/Erlotinib: 1, nal-IRI: 1, surgery: 2). Median PFS and OS were 9.7 (95% CI, 8.9-14.7 mo) and 14.2 months (99% CI, 13.3-23.9 mo), respectively. Median PFS in stage IV patients was 9.2 months (95% CI, 8.4-12.0 mo). Median OS in patients without subsequent treatment was 10.8 months (95% CI, 9.1-13.8 mo). Median OS in patients with subsequent treatment was 19.3 months (95% CI, 18.9-31.9 mo). Grade 4 treatment-related hematological toxicities were encountered in 7 patients. Two patients developed grade 3 allergic reaction after 6 cycles or later. No febrile neutropenia has been observed. CONCLUSION: NAM/GEM/S-1 therapy is safe and could be promising option for unresectable pancreatic cancer, especially for stage IV cancer.

The patient was a 61-year-old woman with a history of diabetes mellitus who had undergone ileocecal resection for ascending colon carcinoma 5 years earlier, followed by a postoperative adjuvant chemotherapy with XELOX (capecitabine + oxaliplatin). During follow-up, the liver gradually atrophied, and radiological imaging showed suspicious findings of 20 × 14 mm hepatocellular carcinoma (HCC) in the right lobe of the liver. The patient also underwent endoscopic variceal ligation for the esophageal varices. She was referred to our hospital for living donor liver transplantation (LDLT) due to decompensated liver cirrhosis with HCC. The patient did not have hepatitis B or C, and history of alcohol, suggesting that her liver cirrhosis was caused by a non-alcoholic steatohepatitis. The Child-Pugh score was 10 points (class C) and the Model for End-Stage Liver Disease (MELD) score was 8 points. The possibility of HCC could not be ruled out, and LDLT was performed. Postoperative pathological examination revealed idiopathic portal hypertension (IPH), and the mass lesion was diagnosed as focal nodular hyperplasia (FNH). The postoperative course was uneventful and the patient was discharged on postoperative day 14. This is the first case of liver transplantation for IPH with FNH.
