Abstract
Biliary tract cancer, which includes intrahepatic cholangiocarcinoma, extrahepatic bile duct cancer, gallbladder cancer, and ampullary cancer, is an intractable disease with a dismal prognosis. Prognosis is particularly poor in cases involving vessels or lymph nodes. Hepatobiliary pancreatic surgeons worldwide have consistently focused on improving surgical treatment, perioperative management, and chemotherapy to improve the outcomes of these diseases. There has been significant progress even in the last 2 years (2017 and 2018), such as promising findings reported by studies on the optimal extent of surgical treatment and multi-institutional randomized controlled trials on adjuvant chemotherapy. We overview the current trends and advancements made in surgical treatment in 2017 and 2018.

Abstract
e14306 Background: Even with curative resection, the recurrence rate of HCC is still high, and no effective adjuvant therapy is currently available. Our previous Phase I study with novel therapeutic peptides and immune adjuvants demonstrated the safety, antigen specific CTL induction in PBMC and a sign of efficacy (ASCO 2017 Abstract # 3086); thus, we started Phase I study of the same therapy as a perioperative immunotherapy setting in patients with resectable HCC (UMIN000029991). Methods: Two mg each of HLA-A*24:02, 02:01, or 02:06 restricted HSP70- and GPC3-derived peptides, in combination with hLAG-3Ig (1.0 mg) + Poly-IC:LC (1.4 mg) were injected intradermally at four sites of the inguinal and axillary regions every week for 6 weeks before surgery. Patients subsequently received 10 injections of adjuvant immunotherapy over 4 months. Surgical specimens and PBMCs were analyzed by mass cytometry (CyTOF), using 66 antibodies to monitor T cell exhaustion, T cell activation, Effector Treg induction, etc. Tumor specimens were also subjected to immunohistochemical staining of CD3, CD8, PD1, HSP70, and GPC3. The reason for early reporting is the interesting findings at the foci of HCC, and the interim analyses was approved by the Data and Safety Monitoring Committee. Results: Of the 11 screened patients, 5 completed the treatments and were analyzed. We found massive CD8+ T lymphocyte infiltration in the intratumor foci of HCC, which is usually accompanied by peritumoral lymphocytic infiltration. Moreover, the density of lymphocytes was markedly higher in areas of HSP70 or GPC3 antigen expression. One case out of five recurred 5 month after surgery and it showed low CD8+ and PD1+ cell infiltration and high effector Treg (CD4+/CD25+/CD45RA-/FoxP3 +) infiltration. This trend was not observed in PBMC, suggesting the importance of TIL analysis. The high PD1 expression was accompanied by massive intratumoral infiltration of CD8+ lymphocytes. Conclusions: The novel therapeutic peptide and immune adjuvant combination induced sustained immune cell infiltration into tumor microenvironments, especially those presenting target tumor-associated antigens. Our novel immunotherapy may convert cold tumors into hot tumors containing PD1+ lymphocytes. Thus, the combination of this novel strategy with PD (L) 1 antibody is warranted. Clinical trial information: 000029991.

Abstract
We have performed a combination therapy of hepatic arterial infusion chemotherapy(HAIC), radiation therapy(RT), and surgical resection for the treatment of hepatocellular carcinoma(HCC)with portal vein tumor thrombosis(PVTT)since 2013. We retrospectively analyzed 36 patients with HCC with PVTT who underwent hepatectomy between 1995 and 2016 to evaluate the clinical outcomes. Ten patients received preoperative HAIC, 7 underwent RT, and 14 received postoperative HAIC. The median survival time(MST)was 19.3 months, and the MST was significantly longer in the patients who underwent curative resection than those in patients who did not. In the non-curative resection group, postoperative HAIC prolonged the survival.

Abstract
A 77-year-old man underwent a follow-up examination after distal gastrectomy. Contrast-enhanced computed tomography revealed a tumor of the pancreatic body and tail that contacted the common hepatic artery/celiac artery. Subsequently, the tumor was diagnosed as a borderline resectable pancreatic cancer. After chemoradiation therapy, the tumor was considered resectable. Preoperative angiography with intraoperative contrast-enhanced ultrasonography and indocyanine green fluorescence imaging confirmed blood flow in the residual stomach. Postoperatively, ischemic necrosis of the residual stomach was not observed. After distal gastrectomy, distal pancreatectomy with en bloc celiac axis resection was performed to safely and curatively address the cancer of the pancreatic body and tail.

Abstract
Case 1: A 64-year-old man with a chiefcomplaint ofbloody stools was seen in our hospital. He underwent an extended right lobe resection for hilar cholangiocarcinoma 3 years ago and was in the middle of chemotherapy for multiple metastases. Case 2: A 69-year-old man with a chiefcomplaint ofbloody emesis and stools was seen. He underwent left hepatic trisegmentectomy for hilar cholangiocarcinoma and ligation of the right portal vein for postoperative portal venous thrombus 6 months ago. After careful examination, the patients in both cases were diagnosed with bleeding of the jejunal varices formed at the site ofhepaticojejunostomy. The patient in Case 1 underwent percutaneous transhepatic obliteration ofvarices and the patient in Case 2 underwent transileocolic vein obliteration ofvarices. After hepatobiliary pancreatic surgery with biliary tract reconstruction, we should be aware of ectopic varices during differential diagnosis of gastrointestinal bleeding.

Abstract
OBJECTIVE Malnutrition is common in patients with esophageal cancer, resulting in increased postoperative complications and mortality. Although preoperative immunonutrition can significantly reduce the incidence of postoperative infectious complications, its effect in patietns with esophageal cancer undergoing esophagectomy remains unclear. The aim of this study was to investigate the effects of perioperative immunonutritional support on the postoperative course and long-term survival of this group of patients. METHODS This prospective, randomized study enrolled 40 patients with thoracic esophageal carcinoma undergoing esophagectomy. The patients were divided into two groups and received either immunomodulating enteral nutrition (IMPACT group; IG) or standard enteral nutrition (Ensure group; EG) continuously for 7 d before and 7 d after surgery. Nutritional status, such as rapid turnover protein, postoperative intensive care unit (ICU) length of stay (LOS), postoperative hospital LOS, morbidity, and mortality were investigated prospectively. RESULTS There were no significant differences in patient demographic characteristics between the two groups. Levels of retinol-binding protein, as a rapid-turnover protein, were significantly higher on postoperative day (POD) -1, 7, and 14 in the IG compared with the EG group (P = 0.009, P = 0.004, and P = 0.024, respectively). The incidence of postoperative infectious complications and changes to therapeutic antibiotics were significantly lower in the IG group than in the EG group (P = 0.048 and P = 0.012, respectively). There was no significant difference in postoperative ICU or postoperative hospital LOS between the two groups. The 5-y progression-free survival rates in the IG and EG groups were 75% and 64%, respectively (P = 0.188), and the overall survival rates were 68% and 55%, respectively (P = 0.187). CONCLUSIONS Perioperative immunonutrition may improve early postoperative nutritional status and reduce postoperative infectious complications in patients with esophageal cancer undergoing esophagectomy.

Abstract
Barrett's esophagus (BE) is the only known precursor to esophageal adenocarcinoma (EAC). Based on striking aggregation of breast cancer and BE/EAC within families as well as shared risk factors and molecular mechanisms of carcinogenesis, we hypothesized that BE may be associated with breast cancer. Pedigree analysis of families identified prospectively at multiple academic centers as part of the Familial Barrett's Esophagus Consortium (FBEC) was reviewed and families with aggregation of BE/EAC and breast cancer are reported. Additionally, using a matched case-control study design, we compared newly diagnosed BE cases in Caucasian females with breast cancer (cases) to Caucasian females without breast cancer (controls) who had undergone upper endoscopy (EGD). Two familial pedigrees, meeting a stringent inclusion criterion, manifested familial aggregation of BE/EAC and breast cancer in an autosomal dominant inheritance pattern with incomplete penetrance. From January 2008 to October 2016, 2812 breast cancer patient charts were identified, of which 213 were Caucasian females who underwent EGD. Six of 213 (2.82%) patients with breast cancer had pathology-confirmed BE, compared to 1 of 241 (0.41%) controls (P-value < 0.05). Selected families with BE/EAC show segregation of breast cancer. A breast cancer diagnosis is marginally associated with BE. We postulate a common susceptibility between BE/EAC and breast cancer.

Abstract
Cancer vaccines have been developed as a new therapeutic approach, however, their clinical benefit remains limited. We previously performed a phase II study for advanced colorectal cancer (CRC) using five human leukocyte antigen (HLA-A*24:02)-restricted peptides derived from kinase of the outer chloroplast membrane 1, translocase of outer mitochondrial membrane 34 (TOMM34), ring finger protein 43 (RNF43), vascular endothelial growth factor receptor 1 (VEGFR1) and VEGFR2. In the present study the relationship between overall survival (OS) and several biomarkers, including cytotoxic T lymphocyte (CTL) and immunoglobulin G (IgG) responses to these five peptides, was investigated. In 89 advanced CRC patients treated with a combination therapy consisting of these five peptides and oxaliplatin-based chemotherapy, plasma was collected before and after 3 months of vaccine administration. IgGs reactive to each of the five peptides were assessed using the multiplex bead suspension Luminex system. Antigen-specific T-cell responses were estimated by enzyme-linked immunoSpot assay. Plasma levels of TOMM34 IgG (P<0.001), RNF43 IgG (P<0.001) and VEGFR2 IgG (P<0.001) were significantly increased after vaccination and stronger VEGFR2 IgG responses correlated significantly with OS in HLA-matched patients (P=0.034). CTL responses to VEGFR1 and VEGFR2 were also significantly increased in the HLA-matched group (P=0.049 and P<0.001, respectively). However, increased CTL response did not correlate with OS. Multivariate analysis indicated that IgG responses to VEGFR2 were the most significant predictor for OS in the HLA-A*24:02-matched group (P=0.04). Our findings indicated that VEGFR2 IgG responses may be an important immunological biomarker in the early course of treatment for CRC patients treated with therapeutic epitope peptides.

Abstract
Many diseases of the gastrointestinal tract have been attributed to chronic inflammation, and a few have identified the role of inflammasomes in their pathogenesis. Inflammasomes are a group of protein complexes comprising of several intracellular proteins that link the sensing of microbial products and metabolic stress to the proteolytic activation of the proinflammatory cytokines. Recent studies have implicated activation of several families of NOD-like receptors (NLRs) which are major components of inflammasomes in the development and exacerbation of many diseases of human systems. In this chapter, we discuss the role of inflammasomes in some of the most prevalent diseases of the gastrointestinal tract and highlight potential targets for treatment.

Abstract
Many clinical trials of peptide vaccines have been conducted. However, these vaccines have provided clinical benefits in only a small fraction of patients. The purpose of the present study was to explore microRNAs (miRNAs) as novel predictive biomarkers for the efficacy of vaccine treatment against colorectal cancer. First, we carried out microarray analysis of pretreatment cancer tissues in a phase I study, in which peptide vaccines alone were given. Candidate miRNAs were selected by comparison of the better prognosis group with the poorer prognosis group. Next, we conducted microarray analysis of cancer tissues in a phase II study, in which peptide vaccines combined with chemotherapy were given. Candidate miRNAs were further selected by a similar comparison of prognosis. Subsequently, we carried out reverse‐transcription PCR analysis of phase II cases, separating cancer tissues into cancer cells and stromal tissue using laser capture microdissection. Treatment effect in relation to overall survival (OS) and miRNA expression was analyzed. Three miRNA predictors were negatively associated with OS: miR‐125b‐1 in cancer cells (P = 0.040), and miR‐378a in both cancer cells (P = 0.009) and stromal cells (P < 0.001). Multivariate analysis showed that expression of miR‐378a in stromal cells was the best among the three predictors (HR, 2.730; 95% CI, 1.027–7.585; P = 0.044). In conclusion, miR‐125b‐1 and miR‐378a expression might be considered as novel biomarkers to predict the efficacy of vaccine treatment against colorectal cancer.

Abstract
MicroRNAs (miRNAs/miRs) regulate the levels of transcripts and serve a critical function in the regulation of tumor microenvironments. Therefore, miRNA levels in cancer tissues are thought to be potential biomarkers for immunotherapy. From a phase I trial of a vaccine treatment using 5 human leukocyte antigen (HLA)-A*2402-restricted peptides (registration no. UMIN000004948), colorectal cancer (CRC) tissues were obtained from 8 patients and normal colorectal tissues from 5 patients via surgery. From a phase II trial using the same peptides (registration no. UMIN000001791), CRC tissues were obtained from 16 patients from the HLA-A*2402-matched group and 10 patients from the HLA-A*2402-unmatched group. These tissues were used for miRNA microarray analysis. As the first step, cancer tissues from the phase I study were used and 10 candidate miRNAs were selected by comparing the miRNA expression between two groups; one with improved prognosis and the other with poor prognosis. The miRNAs were subsequently validated using the cases enrolled in the phase II study. Significantly improved prognoses were identified in 16 patients in the HLA-A*2402-matched group with high expression of miR-196b-5p and low expression of miR-378a-3p and miR-486-5p. There was no difference in prognosis in the 10 patients in the HLA-A*2402-unmatched group. Therefore, high miR-196b expression and low miR-378a-3p and miR-486-5p expression were indicated as useful biomarkers for prediction of the efficacy of vaccine treatment for patients with metastatic CRC. In a planned phase III study, expression levels of these 3 miRNAs (miR-196b-5p, miR-378a-3p and miR-486-5p) may be useful biomarkers for assessing patients who are likely to have an improved outcome following vaccination.

A phase II, multicenter, single-arm study of tri-weekly low-dose nanoparticle albumin-bound paclitaxel chemotherapy for patients with metastatic or recurrent breast cancer. Breast Cancer 2017; 24:783-789. [PMID: 28439763 DOI: 10.1007/s12282-017-0779-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2017] [Accepted: 04/20/2017] [Indexed: 11/29/2022]
Abstract
BACKGROUND Nanoparticle albumin-bound (nab)-paclitaxel is a solvent-free formulation of paclitaxel that is bound to albumin and has demonstrated improved progression free survival in previous studies of breast cancer. However, it is difficult to treat Japanese patients with metastatic or recurrent breast cancer with the recommended dose of 260 mg/m2 of (nab)-paclitaxel for more than six cycles due to the occurrence of adverse events. To evaluate the treatment continuity and safety of low-dose nab-paclitaxel, we conducted a phase II study of nab-paclitaxel in patients with metastatic or recurrent breast cancer who had received up to one prior chemotherapy. PATIENTS AND METHODS Treatment included low doses of 180 mg/m2 nab-paclitaxel that were administered on day 1 of each 3-week cycle to 35 patients. The primary endpoint was the completion rate of six cycles of treatment. RESULTS A total of 35 eligible patients were enrolled and received a median of eight (range 2-24) cycles of low-dose nab-paclitaxel therapy. The completion rate of six cycles of treatment was 66%. ORR and clinical benefit rate was 23 and 71%, respectively. Median PFS was 6.5 months and median OS was 44 months. Adverse events were relatively mild. Commonly observed grade 3/4 adverse events were neutropenia (46%), leukopenia (9%), and hypertension (3%). No grade 3-4 peripheral sensory neuropathy occurred. CONCLUSION Treatment with a low dose of nab-paclitaxel once every 3 weeks was tolerable and of acceptable safety and might be beneficial for patients with metastatic or recurrent breast cancer.

Abstract
Background The purpose of the present study was to explore novel biomarkers that can predict the clinical outcome of patients before treatment or during vaccination. These would be useful for the selection of appropriate patients who would be expected to exhibit better treatment outcomes from vaccination, and for facilitating the development of cancer vaccine treatments. Methods From a single-arm, non-randomized, human leukocyte antigen (HLA)-A-status-blind phase II trial of a vaccine treatment using three HLA-A*2402-restricted peptides for advanced pancreatic cancer (PC), we obtained peripheral blood samples from 36 patients of an HLA-A*2402-matched group and 27 patients of an HLA-A*2402-unmatched group. Results Multivariate analysis (HR = 2.546; 95% CI = 1.138 to 5.765; p = 0.0231) and log-rank test (p = 0.0036) showed that a high expression level of programmed death-1 (PD-1) on CD4+ T cells was a negative predictive biomarker of overall survival in the HLA-A*2402-matched group . Moreover, a high expression level of PD-1 on CD4+ T cells was a negative predictor for the induction of cytotoxic T lymphocytes (p = 0.0007). After treatment, we found that the upregulation of PD-1 and T cell immunoglobulin mucin-3 (Tim-3) expression on CD4+ and CD8+ T cells was significantly associated with a poor clinical outcome in the HLA-A*2402-matched group (p = 0.0330, 0.0282, 0.0046, and 0.0068, respectively). In contrast, there was no significant difference for these factors in the HLA-A*2402-unmatched group. Conclusions Our results indicate that the upregulation of PD-1 and Tim-3 expression on CD4+ and CD8+ T cells may restrict T cell responses in advanced PC patients; therefore, combination immunotherapy with blockade of PD-1 and Tim-3 to restore T cell responses may be a potential therapeutic approach for advanced PC patients.

Highly sensitive faecal DNA testing of TWIST1 methylation in combination with faecal immunochemical test for haemoglobin is a promising marker for detection of colorectal neoplasia.

Abstract
Background As TWIST1 methylation is specific to colorectal neoplasia, detection of TWIST1 methylation from faeces samples might be useful for colorectal neoplasia screening. However, because the content of human DNA in faeces is very small, it is very difficult to detect TWIST1 methylation by conventional bisulphite-based methylation assays. Therefore, we developed a new methylation assay without bisulphite treatment, the combined restriction digital PCR assay, and evaluated its sensitivity and specificity in combination with and without the faecal immunochemical test for haemoglobin for colorectal neoplasia detection from faeces samples. Methods For the combined restriction digital PCR assay, DNA was treated with three methylation-sensitive restriction enzymes and an exonuclease, followed by measurement of TWIST1 methylation level by droplet digital PCR. Faecal DNA testing and faecal immunochemical test for haemoglobin were performed on 109 patients with colorectal neoplasia and 10 control individuals. Results Basic performance testing showed that the combined restriction digital PCR assay enabled detection of 0.14% of the TWIST1 methylation level for the lymphocyte DNA. The combined restriction digital PCR assay from faeces samples had a sensitivity of 22.2% (95% confidence interval, 2.8–60.0%) for non-advanced adenoma, 47.1% (95% confidence interval, 23.0–72.2%) for advanced adenoma, and 33.7% (95% confidence interval, 23.7–45.0%) for colorectal cancer, and a specificity of 100.0%. Combination of faecal immunochemical test for haemoglobin and faecal combined restriction digital PCR assay increased sensitivity to 82.4% (95% confidence interval, 56.6–96.2%) for the detection of advanced adenoma. Conclusions We developed the combined restriction digital PCR assay, a possible highly sensitive methylation assay. Combination of faecal combined restriction digital PCR assay with faecal immunochemical test for haemoglobin may provide an alternative screening strategy for colorectal neoplasia, especially for potentially precancerous lesions.

Abstract
We previously conducted a phase I clinical trial combining the HLA-A*2402-restricted KIF20A-derived peptide vaccine with gemcitabine for advanced pancreatic cancer (PC) and confirmed its safety and immunogenicity in cancer patients. In this study, we conducted a multicenter, single-armed, phase II trial using two antiangiogenic cancer vaccines targeting VEGFR1 and VEGFR2 in addition to the KIF20A peptide. We attempted to evaluate the clinical benefit of the cancer vaccination in combination with gemcitabine. Chemotherapy naïve PC patients were enrolled to evaluate primarily the 1-year survival rate, and secondarily overall survival (OS), progression free survival (PFS), response rate (RR), disease control rate (DCR) and the peptide-specific immune responses. All enrolled patients received therapy without the HLA-A information, and the HLA genotypes were used for classification of the patients. Between June 2012 and May 2013, a total of 68 patients were enrolled. No severe systemic adverse effects of Grade 3 or higher related to these three peptides were observed. The 1-year survival rates between the HLA-A*2402-matched and -unmatched groups were not significantly different. In the HLA-A*2402 matched group, patients showing peptide-specific CTL induction for KIF20A or VEGFR1 showed a better prognosis compared to those without such induction (P = 0.023, P = 0.009, respectively). In the HLA-A*2402-matched group, the patients who showed a strong injection site reaction had a better survival rate (P = 0.017) compared to those with a weak or no injection site reaction. This phase II study demonstrated that this therapeutic peptide cocktail might be effective in patients who demonstrate peptide-specific immune reactions although predictive biomarkers are needed for patient selection in its further clinical application.
