ABSTRACT
BACKGROUND: Early tumor shrinkage (ETS) is a prognostic predictor for patients treated with chemotherapy in colorectal cancer, although scarce studies evaluated its potential in locally advanced pancreatic cancer (LAPC). In this exploratory analysis of JCOG1407, a randomized phase II study comparing modified 5-fluorouracil, levofolinate, irinotecan, and oxaliplatin (mFOLFIRINOX) and gemcitabine plus nab-paclitaxel (GnP), we evaluated whether ETS can predict prognosis of patients with LAPC. METHODS: Of the 126 patients enrolled in JCOG1407, 112 with measurable lesions were included in this study. ETS was defined as a ≥20 % reduction in tumor diameter compared with baseline at the initial imaging assessment 6-10 weeks after initiating chemotherapy. Patients were divided into the ETS (achieved ETS) and non-ETS (failed to achieve ETS) groups based on their ETS status. The impact of ETS on overall survival (OS) was compared using multivariable Cox regression analysis. RESULTS: Fourteen of 55 (25.5 %) and 24 of 57 (42.1 %) patients in the mFOLFIRINOX and GnP arms, respectively, achieved ETS. In the overall population, mFOLFIRINOX arm, and GnP arm, the median OS in the ETS and non-ETS groups was 27.1 and 20.4, 29.8 and 20.6, and 24.1 and 20.4, months, respectively. The adjusted hazard ratios of OS for the ETS group in the overall population, mFOLFIRINOX arm, and GnP arm were 0.451 (95 % confidence interval [CI]: 0.270-0.754), 0.371 (95 % CI: 0.149-0.926), and 0.508 (95 % CI: 0.255-1.004), respectively. CONCLUSIONS: ETS may be a prognostic predictor in chemotherapy-naïve patients with LAPC treated with mFOLFIRINOX or GnP.

A 72-year-old man with metastatic hepatocellular carcinoma previously received first-line systemic therapy with atezolizumab plus bevacizumab. His disease was judged to be progressing 5 months after treatment initiation. Comprehensive genomic profiling revealed cytoplasmic mesenchymal-epithelial transition factor amplification. On the basis of an expert panel's recommendation, he received cabozantinib as second-line therapy. The tumors shrank markedly and continued to shrink 6 months after treatment. Comprehensive genomic profiling could provide useful information for selecting effective second-line treatments for patients with hepatocellular carcinoma after first-line immunotherapy.
ABSTRACT
The number of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) patients persists even under nucleos(t)ide analogues (NAs) treatment. Aldo-keto reductase family 1 member B10 (AKR1B10) expression has been reported in advanced chronic liver diseases as well as cancer tissues. We observed an association between related to HCC incidence and serum AKR1B10 by analyzing patients under treatment with NAs. Serum AKR1B10 levels measured by ELISA were higher in HCC cases under NA treatment compared with non-HCC cases and were associated with lamivudine- and adefovir pivoxil-, but not entecavir- or tenofovir alafenamide-treated cases. The latter drugs did not increase AKR1B10 values even in HCC cases, suggesting that they influence the reduction of AKR1B10 in any cases. This analysis was supported by in-vitro examination, which showed reduced AKR1B10 expression by entecavir and tenofovir via immunofluorescence staining. In conclusion there was a relationship between HBV-related HCC incidence and AKR1B10 under nucleos(t)ide analogues, especially in the use of lamivudine and adefovir pivoxil, but entecavir and tenofovir had suppressive effects of AKR1B10.

Liver function influences the plasma antithrombin (AT)-III levels. AT-III is beneficial for patients with portal vein thrombosis (PVT) and low plasma AT-III levels. However, whether these levels affect prognosis in patients with cirrhosis-associated PVT remains unknown. This retrospective study involved 75 patients with cirrhosis and PVT treated with danaparoid sodium with or without AT-III. The plasma AT-III level was significantly lower in patients with liver failure-related death than in those with hepatocellular carcinoma (HCC)-related death (p = 0.005), although the Child-Pugh and albumin-bilirubin (ALBI) scores were not significantly different between these two groups. Receiver operating characteristic curve analysis of the plasma AT-III levels showed cutoff values of 54.0% at 5-year survival. Low plasma AT-III levels (<54.0%) were associated with significantly worse prognosis than high levels in both overall survival (p = 0.0013) and survival excluding HCC-related death (p < 0.0001). Low plasma AT-III (<54.0%) was also associated with a significantly worse prognosis among patients with Child-Pugh A/B or ALBI grade 1/2 (p < 0.0001). Multivariate analyses indicated that low plasma AT-III levels (<54.0%) were an independent prognostic factor for poor survival outcome. Low plasma AT-III levels may be associated with mortality, particularly liver failure-related death, independent of liver function.

Immune-related adverse events (irAE) has been clarified according the usage of immune checkpoint inhibitors(ICI). We primarily found indoleamine 2,3-dioxygenase 1(IDO-1) as a histologic biomarker for the cholangiopathy of primary biliary cholangitis(PBC). In this study, we evaluated the utility of IDO-1 in identifying ICI-induced immune-mediated hepatotoxicity(IMH). Immunostaining for IDO-1 using liver sections of PBC, ICI-induced IMH and controls, revealed that IDO-1 expression in bile ducts is mostly restricted in PBC and ICI-induced IMH. In ICI-induced IMH, IDO-1-positive bile ducts is found in 2/2 cases of cholangitis type and also positive/focal ducts in 11/15 cases of hepatitis type. Moreover, in 8/13 positive/focal cases, ursodeoxycholic acid as well as steroids were needed to improve liver dysfunction, but just one case (1/4) in IDO-1-negative cases. One IDO-1 positive case of hepatitis type did not receive additional UDCA, but biliary enzymes worsen. In vitro study using cultured human biliary epithelial cells revealed that IDO-1 induction was found with the stimulation of IFN-γ. In conclusion, the presence of IDO-1-positive cells is found in bile ducts in hepatitic type as well as sclerosing cholangitis of ICI-induced IMH. IDO-1 is surely a valuable pathologic marker for diagnosing ICI-induced IMH and also for predicting an additional need of UDCA in clinical practice.

BACKGROUNDS AND AIMS: Structural dynamics of basement membrane components are still to be elucidated in the process of hepatocarcinogenesis. We evaluated the characteristics of HCC expressing laminin γ2 monomer (LG2m), a basement membrane component not detected in normal tissues, for HCC diagnosis. We further determined whether elevated serum LG2m is a risk factor for HCC development in patients with chronic hepatitis C (CHC). APPROACH AND RESULTS: In HCC cell lines, LG2m was expressed in alpha-fetoprotein (AFP)-negative, CD90-positive cells characterized by highly metastatic natures. Using 14 cell lines and 258 HCC microarray data, we identified that LG2m gene signature was associated with Hoshida's S1/Boyault's G3 molecular subclasses with poor prognosis, which could not be recognized by AFP. Serum LG2m was assessed in 24 healthy donors, 133 chronic liver disease patients, and 142 HCC patients, and sensitivity and specificity of LG2m testing for HCC diagnosis were 62.9% and 70.5%, respectively (cutoff, 30 pg/mL). We evaluated the consequence of LG2m elevation in two independent HCC cohorts (n = 47 and n = 81), and LG2m-high HCC showed poor prognosis with later development of distant organ metastasis (cutoff, 60 pg/mL). LG2m was slightly elevated in a subset of CHC patients, and Kaplan-Meier analysis indicated a high incidence of HCC (n = 70). For validation, we enrolled 399 CHC patients with sustained virological response (SVR) as a multicenter, prospective study, and serum LG2m elevation correlated with a high incidence of HCC in the CHC patients with SVR (P < 0.0001). CONCLUSIONS: LG2m is a predictive biomarker for the development of metastatic HCC. Elevated serum LG2m is an HCC risk in CHC patients who have achieved SVR.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has rapidly and dramatically influenced healthcare across Japan. However, the influence of the COVID-19 pandemic on the number of newly diagnosed cancer, surgical treatment, and diagnostic examination for cancer types have not been completely investigated all over Japan. This study aimed to analyze the number of cases before and during the COVID-19 pandemic. METHODS: This retrospective study was a survey that asked to provide the number of cases diagnosed with gastric, colorectal, lung, breast, and cervical cancer between January 2019 and December 2020. The survey was sent to tertiary healthcare hospitals, including national cancer institutions, university hospitals, and general hospitals, all over Japan. Data obtained from 105 of 486 surveyed hospitals were evaluated, and the number of cases in each quarter in 2020 was compared with that in the equivalent quarter in 2019. RESULTS: In the second quarter (Q2), significant reductions were observed in the median number of newly diagnosed cases from 2019 to 2020: gastric cancer, 26.7% (43 vs. 32, p < 0.001); colorectal cancer, 17.9% (52 vs. 40, p < 0.001); lung cancer, 12.3% (53.5 vs. 47, p < 0.001); and breast cancer, 13.1% (43 vs. 35.5, p < 0.001). A significant reduction of 11.4% (9 vs. 8, p = 0.03) was observed in the third quarter (Q3) for cervical cancer. In Q2, the number of cases decreased by 30.9% (25 vs. 15, p < 0.001) for stage I gastric cancer, by 27.3% (12 vs. 9, p < 0.001) for stage I colorectal cancer, and by 17.6% (13 vs. 10, p < 0.001) for stage II breast cancer. The magnitude of reduction was significant for the localized stages of gastric, colorectal, and breast cancer according to diagnostic examinations in Q2 and surgical and endoscopic treatment in Q3 rather than that for lung or cervical cancer. CONCLUSIONS: COVID-19 has prolonged collateral effects on cancer care, including examination, diagnosis, and surgery, with significant effects on gastric cancer, followed by colorectal, lung, breast, and cervical cancer in Japan.

BACKGROUND/OBJECTIVES: Pancreatic adenosquamous carcinoma (PASC) is a rare variant of pancreatic ductal adenocarcinoma (PDAC). The usual treatment for metastatic or recurrent PASC is systemic chemotherapy in accordance with the PDAC treatment strategy. This study aimed to investigate the efficacy of chemotherapy, especially the benefit of recent combination therapies, in patients with metastatic or recurrent PASC. METHODS: We conducted a multicenter retrospective analysis of 116 patients with metastatic or recurrent PASC treated with first-line chemotherapy between April 2001 and December 2017 at 24 Japanese institutions. RESULTS: Combination chemotherapies included gemcitabine + nab-paclitaxel (GnP, n = 28), fluorouracil/leucovorin + irinotecan + oxaliplatin (FFX, n = 10), gemcitabine + S-1 (GS, n = 10), and others (n = 9). Monotherapies included gemcitabine (n = 51) and S-1 (n = 8). The median overall survival (OS) was 6.5, 7.3, and 4.3 months for the whole cohort, the combination therapy group, and the monotherapy group, respectively. Multivariate analysis indicated that combination therapy showed a better trend in OS than monotherapy (hazard ratio = 0.68; 95% confidence interval, 0.38-1.20). GnP or FFX were selected in 58.7% of patients after FFX was approved in Japan, and revealed a median OS, median progression-free survival, and objective response rate of 7.3 months, 2.8 months, and 26.9% in GnP and 7.2 months, 2.3 months, and 20.0% in FFX respectively. CONCLUSIONS: This study suggests that combination therapy may be more effective than monotherapy. GnP and FFX showed similar and clinically meaningful efficacy for patients with metastatic or recurrent PASC.

AIM: To compare the total medical costs and treatment outcomes in patients with primary hepatocellular carcinoma (HCC) according to their initial treatment, that is, hepatectomy or radiofrequency ablation (RFA), in real-world clinical practice in Japan. METHODS: This retrospective observational study was conducted using a medical claims database. Patients who underwent hepatectomy or RFA for primary HCC were matched using propensity score matching methods for available baseline characteristics. The average per-patient total medical costs from the date of initial treatment to up to 3 years were estimated. The 3-year survival and recurrence rates were estimated using the Kaplan-Meier method. RESULTS: Data of 1726 patients (863 in each group) were analyzed. The average 3-year medical costs were USD 8000 lower in the RFA group than in the hepatectomy group (USD 35,000 vs. USD 43,000). Patients in the RFA group had comparable 3-year overall survival to those in the hepatectomy group (87.6% vs. 90.4%). However, the 3-year recurrence rate was significantly higher in the RFA group than in the hepatectomy group (41.5% vs. 30.8%; hazard ratio = 1.56, 95% confidence interval: 1.31-1.87). CONCLUSIONS: In this 3-year study, patients achieved similar survival rates irrespective of initial treatment, but the RFA group had a lower total medical cost burden than the hepatectomy group. If both treatments are equally feasible, RFA may be a preferable initial curative treatment for primary HCC. However, careful consideration and adequate treatment should be given due to its higher recurrence risk.
ABSTRACT
BACKGROUND: Our phase II trial (FABRIC study) failed to verify the efficacy of gemcitabine plus oxaliplatin (GEMOX) in patients with pancreatic ductal adenocarcinoma (PDAC) with a familial or personal history of pancreatic, breast, ovarian or prostate cancer, which suggested that a family and personal history may be insufficient to determine response to platinum-based chemotherapy. METHODS: This ancillary analysis aimed to investigate the prevalence of germline variants of homologous recombination repair (HRR)-related genes and clarify the association of germline variants with the efficacy of GEMOX and patient outcome in PDAC patients. Of 45 patients enrolled in FABRIC study, 27 patients were registered in this ancillary analysis. RESULTS: Of the identified variants in HRR-related genes, one variant was considered pathogenic and eight variants in six patients (22%) were variants of unknown significance (VUS). Objective response to GEMOX was achieved by 43% of the seven patients and tended to be higher than that of patients without such variants (25%). Pathogenic/VUS variant in HRR-related genes was an independent favorable factor for progression-free survival (hazard ratio, 0.322; P = 0.047) and overall survival (hazard ratio, 0.195; P = 0.023) in multivariable analysis. CONCLUSIONS: The prevalence of germline variants in PDAC patients was very low even among patients with a familial/personal history of pancreatic, breast, ovarian or prostate cancer. Patients with one or more germline variants in HRR-related genes classified as pathogenic or VUS may have the potential to obtain better response to GEMOX and have better outcomes.

BACKGROUND: Accurate prognostic understanding in patients with advanced cancer is essential for shared decision making; however, patients may experience psychological burden through knowing the incurable nature of advanced cancer. It has been unclear how their prognostic understanding fluctuates and whether accurate prognostic understanding is associated with psychological distress from the time of diagnosis over time. MATERIALS AND METHODS: We longitudinally investigated prognostic understanding in 225 patients with newly diagnosed advanced lung cancer at 16 hospitals in Japan until 24 months after diagnosis. We examined associated factors with being consistently accurate in prognostic understanding, especially focusing on its association with psychological well-being. RESULTS: The proportion of patients with an inaccurate prognostic understanding remained approximately 20% over time with the presence of patients with inconsistent understanding. Patients with consistently accurate prognostic understanding showed a significantly lower Emotional Well-Being subscale score at both 3 and 6 months after diagnosis (p = .010 and p = .014, respectively). In multivariate analyses, being consistently accurate in prognostic understanding was significantly associated with female gender and higher lung cancer-specific symptom burden at 3 months (p = .008 and p = .005, respectively) and lower emotional well-being at 6 months (p = .006). CONCLUSION: Although substantial proportions of patients with advanced lung cancer had inaccurate prognostic understanding from the time of diagnosis over time, patients with consistently accurate prognostic understanding experienced greater psychological burden. Our findings highlight the importance of continuous psychological care and support for patients who understand their severe prognosis accurately. IMPLICATIONS FOR PRACTICE: This study demonstrated that approximately 20% of patients with advanced lung cancer had an inaccurate understanding about their prognosis, not only at the time of diagnosis but also at the later time points. Being consistently accurate in prognostic understanding was significantly associated with elevated levels of psychological distress. Although accurate prognostic understanding is essential for decision making for treatment and advance care planning, health care providers should be aware of psychological burdens in patients that accept their severe prognosis accurately. Appropriate care and support for such patients are warranted from diagnosis over time.

BACKGROUND: Undifferentiated carcinoma (UC) of the pancreas has been considered a highly aggressive malignancy. However, only a few studies have systematically described the clinical course of UC patients. The aim of this study was to clarify the prognosis and construct a prognostic model for patients with unresectable UC. METHODS: This study was conducted at 17 institutions in Japan, and a total of 55 patients were analyzed. RESULTS: The median overall survival (OS) of patients with unresectable UC was 3.95 months. In the multivariate Cox proportional hazards (CPH) model, age ≥65 years, Eastern Cooperative Oncology Group performance status (ECOG PS) ≥2, and C-reactive protein (CRP) >10 mg/L were independent prognostic factors for OS (age ≥65 years: hazard ratio [HR], 2.732; 95% confidence interval [CI], 1.353-5.515; ECOG PS ≥ 2: HR, 7.866; 95% CI, 1.981-31.241; CRP >10 mg/L: HR, 1.956; 95% CI, 1.013-3.775). Based on the ß coefficients from the CPH model, the prognostic scores were defined as follows: age ≥65 years (3 points), ECOG PS ≥ 2 (6 points), and CRP >10 ml/L (2 points). The final prognostic model was the sum of the points. The derived prognostic model stratified patients into high-risk (score ≥4) and low-risk (score 0-3) groups, with significant differences in OS (1.45 vs. 8.19 months, respectively; p < 0.001). CONCLUSIONS: The prognostic model stratified patients into high-risk and low-risk groups. These findings suggest that this model can serve as a tool for patient information and decision-making with regard to the therapeutic strategy for UC.

AIM: To examine the treatment patterns and medical costs in real-world practice among patients who received hepatectomy for hepatocellular carcinoma (HCC) in Japan. METHODS: Data of patients who underwent hepatectomy as an initial therapy for primary HCC were extracted from a Japanese medical claims database from April 2008 to December 2019. The types of additional treatments for recurrent HCC and medical costs for up to 3 years from the first hepatectomy were analyzed. The average cumulative cost per patient starting on the date of the first hepatectomy was calculated using the Kaplan-Meier sample-average method. RESULTS: Data from 2 342 patients (median age, 71 years) were analyzed. Overall, 35.6% of patients received at least one HCC treatment within 3 years of the first hepatectomy. The total average cumulative 3-years medical cost was JPY 4 993 300 (95% confidence interval [CI]: 4 804 100 to 5 220 500). Surgical procedures were the most costly components in the first month after hepatectomy, whereas the costs of drugs, which mainly included antiviral and antineoplastic medications, increased thereafter. Patients with advanced stage HCC, hepatitis C, or a higher Charlson Comorbidity Index at hepatectomy, or those who required additional treatment, especially with antineoplastic drugs for recurrent HCC, incurred higher medical costs. CONCLUSIONS: Patients with HCC after hepatectomy experienced a large economic burden, which was more serious for those with advanced stage HCC, higher comorbidities, and hepatitis at baseline and for patients treated with antineoplastic drugs. A treatment selection that considers its medical cost burden would help to reduce some of these economic burdens.
ABSTRACT
AIM: Sequential administration of sorafenib followed by regorafenib or lenvatinib is effective against advanced hepatocellular carcinoma (HCC). In this study, we compared the safety profiles and anti-tumor effects of sequential sorafenib and regorafenib or lenvatinib therapy in patients with HCC. METHODS: We investigated adverse events, treatment responses and dose intensities in patients with HCC who were consecutively treated with sorafenib followed by regorafenib or lenvatinib at the individual level. RESULTS: Each group included 20 patients. The safety profiles of regorafenib and sorafenib were similar. The severity of hypophosphatemia, palmar-plantar erythrodysesthesia syndrome, and decreased neutrophil counts associated with regorafenib or sorafenib was similar in 12 patients. Conversely, the incidences and grades of adverse events differed between sorafenib and lenvatinib treatment. The anti-tumor effects of regorafenib and lenvatinib compared with sorafenib were significantly different for each patient. The response to treatment and progression-free survival were comparable for regorafenib and lenvatinib. The median relative dose intensities during the first 56 days of regorafenib and lenvatinib treatment were 83.6 and 80.0%, respectively. CONCLUSIONS: Similar adverse events were experienced by patients during consecutive treatment with sorafenib and regorafenib, which was not observed during treatment with sorafenib and lenvatinib. The obtained safety profile of sorafenib provided meaningful insights for selecting sequential therapy for patients with advanced HCC.
ABSTRACT
BACKGROUND: Both advanced cancer patients and their family caregivers experience distress and have a range of concerns after cancer diagnosis. However, longitudinal studies on this topic have been lacking. AIM: To investigate concerns in both patients with advanced lung cancer and their family caregivers longitudinally from diagnosis. DESIGN: A multi-center prospective questionnaire-based study. SETTING/PARTICIPANTS: We recruited patients with newly diagnosed advanced lung cancer and their family caregivers at 16 hospitals in Japan. We prospectively assessed the prevalence of their concerns using the Concerns Checklist and investigated the associations between their concerns and mental status as well as quality of life until 24 months after diagnosis. RESULTS: A total of 248 patients and their 232 family caregivers were enrolled. The prevalence of serious concerns was highest at diagnosis (patients: 68.3%, family caregivers: 65.3%). The most common serious concern was concern about the future in both groups at diagnosis (38.2% and 40.5%, respectively) and this remained high in prevalence over time, while the high prevalence of concern about lack of information improved 3 months after diagnosis in both groups. Approximately one-third of patient-family caregiver dyads had discrepant reports of serious concerns. The presence of serious concerns was significantly associated with anxiety and depression continuously in both groups. CONCLUSIONS: The majority of advanced lung cancer patients and their family caregivers have serious concerns from diagnosis, which is associated with their psychological distress. The spectrum of concerns alters over the disease trajectory, warranting efficient tailored care and support for both groups immediately after diagnosis.

BACKGROUND: Salvage photodynamic therapy with talaporfin sodium has a high local control rate for esophageal cancer after definitive chemoradiotherapy. The eligibility criteria for photodynamic therapy include the absence of invasion to the cervical esophagus and a 3 cm maximum longitudinal lesion length. There is little evidence regarding the efficacy and safety of lesions outside the eligibility criteria. This retrospective cohort study evaluated the efficacy and safety of photodynamic therapy of such lesions. METHODS: Patients with consecutive lesions between February 2016 and May 2020 (n = 36) were enrolled. The local complete response rates and adverse events were compared between patients with cervical and non-cervical lesions and those with lesions larger and smaller than 3 cm. RESULTS: The local complete response rate was 77.8% and was significantly lower in cervical than in non-cervical lesions (20.0% vs 80.6%, p = 0.005). Esophageal stricture, laryngeal pain, and fever were significantly higher in the cervical than in the non-cervical lesion group; however, the detected adverse events were up to grade 2. Laser exposure dose was high in lesions larger than 3 cm (median, 650 vs 400 J; p < 0.001). No significant differences in local complete response rates and adverse effects were noted. One case involving a lesion larger than 3 cm needed balloon dilations for esophageal stricture. CONCLUSIONS: Although salvage esophageal photodynamic therapy was effective for local control with acceptable safety after definitive chemoradiotherapy failure, photodynamic therapy toward cervical lesions had a statistically lower local complete response rate. Lesions larger than 3 cm may be considered treatable.

Dendritic cells (DCs) are antigen-presenting cells with a central role in host immune response. This study analyzed gene expression and DC function in hepatitis B virus (HBV) patients, functions impaired because of HBV, and identified the genes related to these functions. Peripheral blood mononuclear cells from 64 HBV patients and 19 healthy controls were analyzed. Peripheral blood DCs were stained with antibodies against human leukocyte antigen-DR/Lin-1/CD123/CD11c and separated into plasmacytoid DCs (pDCs) and myeloid DCs by fluorescence-activated cell sorting. Using an interferon-gamma enzyme-linked immunospot assay, we analyzed antigen-specific response in HBV-infected patients. Regarding DC function, we analyzed antigen-presenting capacity, cell migration capacity, phagocytic capacity, and cytokine production capacity. DC gene expression was analyzed by microarray to identify genes related to DC function. No difference was found in the number of DCs in peripheral blood between healthy participants and HBV patients. In cell-surface marker analysis, CD80, CD83, CD86, CD40, and C-C motif chemokine receptor 7 expression levels in pDCs were related to the HBV-specific T-cell response. DCs from HBV patients exhibited decreases in antigen-presenting capacity, migration capacity, and cytokine production capacity. In gene expression analysis, immune-related genes with greatly reduced expression levels in chronic hepatitis B patients were identified. Of these genes, interleukin (IL)-6 signal transducer (IL6ST) expression level positively correlated with DC surface marker expression level. Adjustment of IL6ST expression level in DCs and treatment with oncostatin M resulted in recovery of DC function. Conclusion: IL6ST expression was identified as one cause of decline in DC function in HBV patients. Adjustment of IL6 family cytokine signaling may be useful for recovering reduced DC function in HBV infection.

Host antitumor immune responses may be different between hepatocellular carcinoma (HCC) caused by metabolic disorders and HCC associated with hepatitis virus infection. In this study, we examined the immune response of tumor-associated antigen (TAA)-specific T cells and immune cell profile in patients with HCC separated by cause. Thirty-two patients with hepatitis B virus (HBV)-related HCC, 42 patients with hepatitis C virus-related HCC, and 18 patients with nonalcoholic steatohepatitis (NASH)-related HCC were analyzed. The frequencies of TAA-specific T cells, the expression levels of surface markers on each immune cell, and the expression of each TAA in HCC tissue were measured. The immune response to TAA and immune cell profile were markedly different among the three groups. The immune response to TAA in the NASH-related HCC group was weaker than the responses in the other two groups. In patients with NASH-related HCC, the frequencies of effector regulatory T cells (eTregs) and cluster of differentiation 8-positive (CD8+ ) T cells strongly expressing cytotoxic T-lymphocyte antigen (CTLA)-4 were high. The frequency of CD8+ T cells strongly expressing programmed cell death 1 was the highest in patients with HBV-related HCC. Among these immune cell profiles, the frequencies of C-X-C motif chemokine receptor 3+ eTregs and CTLA-4+ CD8+ T cells were inversely correlated with the strength of the TAA-specific T-cell immune response, and the restoration of TAA-specific T-cell responses by anti-CTLA-4 antibody was observed. Conclusion: The immune response to TAA were markedly different among the three groups, and a correlation with the immune cell profile was observed, suggesting that development of immunotherapy based on the etiology of HCC may lead to more effective treatment outcomes.

BACKGROUND: Undifferentiated carcinoma (UC) of the pancreas is a rare subtype of pancreatic cancer. Although UC has been considered a highly aggressive malignancy, no clinical studies have addressed the efficacy of chemotherapy for unresectable UC. Therefore, we conducted multicenter retrospective study to investigate the efficacy of chemotherapy in patients with UC of the pancreas. METHODS: This multicenter retrospective cohort study was conducted at 17 institutions in Japan between January 2007 and December 2017. A total of 50 patients treated with chemotherapy were analyzed. RESULTS: The median overall survival (OS) in UC patients treated with chemotherapy was 4.08 months. The details of first-line chemotherapy were as follows: gemcitabine (n = 24), S-1 (n = 12), gemcitabine plus nab-paclitaxel (n = 6), and other treatment (n = 8). The median progression-free survival (PFS) was 1.61 months in the gemcitabine group, 2.96 months in the S-1 group, and 4.60 months in the gemcitabine plus nab-paclitaxel group. Gemcitabine plus nab-paclitaxel significantly improved PFS compared with gemcitabine (p = 0.014). The objective response rate (ORR) was 4.2% in the gemcitabine group, 0.0% in the S-1 group, and 33.3% in the gemcitabine plus nab-paclitaxel group. Gemcitabine plus nab-paclitaxel also showed a significantly higher ORR compared with both gemcitabine and S-1 (gemcitabine plus nab-paclitaxel vs. gemcitabine: p = 0.033; gemcitabine plus nab-paclitaxel vs. S-1: p = 0.034). A paclitaxel-containing first-line regimen significantly improved OS compared with a non-paclitaxel-containing regimen (6.94 months vs. 3.75 months, respectively; p = 0.041). After adjustment, use of a paclitaxel-containing regimen in any line was still an independent predictor of OS (hazard ratio for OS, 0.221; 95% confidence interval, 0.076-0.647; p = 0.006) in multiple imputation by chained equation. CONCLUSIONS: The results of the present study indicate that a paclitaxel-containing regimen would offer relatively longer survival, and it is considered a reasonable option for treating patients with unresectable UC.

AIM: Most patients with advanced hepatocellular carcinoma (HCC) have underlying chronic liver disease, which potentially deteriorated the liver functional reserve that often affects the patients' clinical course. We investigated and compared the changes in liver functional reserve during lenvatinib or sorafenib therapy in patients with advanced HCC. METHODS: We prospectively collected medical information about patients with advanced HCC with a Child-Pugh score of 5-7 to compare the liver functional reserve during treatment in those who were treated with lenvatinib or sorafenib. We also evaluated the effect of the change in the liver functional reserve on patients' outcome. Moreover, we analyzed the contributing factors for maintaining the liver functional reserve during treatment. RESULTS: Patients were treated with lenvatinib (n = 45) or sorafenib (n = 157). Forty-five patients in the lenvatinib group and 135 patients in the sorafenib group were selected through a propensity score matching analysis. More patients treated with lenvatinib had a Child-Pugh score that was maintained or improved after 4 and 12 weeks compared with those treated with sorafenib (P = 0.048, P = 0.036, respectively). Lenvatinib was identified as one of the variables that was associated with maintaining Child-Pugh scores. Multivariate analysis revealed that a worsened Child-Pugh score after 4 weeks was an independent unfavorable predictive factor for overall survival. CONCLUSIONS: More patients treated with lenvatinib for advanced HCC maintained their liver functional reserves compared with those treated with sorafenib. Maintaining the liver functional reserve contributed to better outcomes for patients with advanced HCC.
