RESUMO
BACKGROUND: Although the combination of atezolizumab and bevacizumab (ATZ + BEV) is a standard treatment for advanced hepatocellular carcinoma (HCC), strategies for addressing treatment failure and prognostic factors of post-progression survival (PPS) remain unestablished. METHODS: We conducted a multicentre retrospective study to evaluate PPS following ATZ + BEV treatment in patients with advanced HCC. We classified the patients into three groups: BCLC stage B and BCLC stage C without or with new extrahepatic lesions (BCLCp-C1 and BCLCp-C2, respectively) at the time of progression. RESULTS: Of the 204 patients who started ATZ + BEV treatment between October 2020 and September 2022, 110 showed disease progression, with 33, 55 and 22 showing the BCLCp-B, BCLCp-C1 and BCLCp-C2 stages of the disease, respectively. Specifically, patients with the BCLCp-B stage of the disease showed better overall survival than those with the BCLCp-C1 and BCLCp-C2 stages (hazard ratios: 1.93 [95% confidence interval, CI, 1.06-3.51] and 2.64 [95% CI, 1.32-5.30] for HCC stages BCLCp-C1 and BCLCp-C2, respectively). Via multivariable analysis, we identified the BCLCp-C1 and BCLCp-C2 stages, as well as performance status, Child-Pugh class and alpha-fetoprotein as poor prognostic factors for PPS. CONCLUSIONS: BCLCp-B1 stage was identified as a better prognostic factor for PPS following ATZ + BEV treatment compared with BCLCp-C1 and BCLCp-C2 stages. This may help in making decisions regarding subsequent treatment after ATZ + BEV.

AIM: This study aims to evaluate the efficacy and safety of lenvatinib radiofrequency ablation (RFA) sequential therapy for certain hepatocellular carcinoma (HCC) patients. METHODS: One hundred and nineteen patients with unresectable HCC in the intermediate stage with Child-Pugh A were retrospectively recruited in a multicenter setting. Those in the lenvatinib RFA sequential therapy group received lenvatinib initially, followed by RFA and the retreatment with lenvatinib. The study compared overall survival (OS), progression-free survival (PFS), tumor response, and adverse events (AEs) between patients undergoing sequential therapy and lenvatinib monotherapy. RESULTS: After propensity score matching, 25 patients on sequential therapy and 50 on monotherapy were evaluated. Independent factors influencing OS were identified as sequential therapy, modified albumin-bilirubin (mALBI) grade, and relative dose intensity (%) with hazard ratios (HRs) of 0.381 (95% confidence interval [CI], 0.186-0.782), 2.220 (95% CI, 1.410-3.493), and 0.982 (95% CI, 0.966-0.999), respectively. Stratified analysis based on mALBI grades confirmed the independent influence of treatment strategy across all mALBI grades for OS (HR, 0.376; 95% CI, 0.176-0.804). Furthermore, sequential therapy was identified as an independent factor of PFS (HR, 0.382; 95% CI, 0.215-0.678). Sequential therapy significantly outperformed monotherapy on survival benefits (OS: 38.27 vs. 18.96 months for sequential therapy and monotherapy, respectively, p = 0.004; PFS: 13.80 vs. 5.32 months for sequential therapy and monotherapy, respectively, p < 0.001). Sequential therapy was significantly associated with complete response by modified Response Evaluation Criteria in Solid Tumors (odds ratio, 63.089). Ten of 119 patients experienced grade 3 AEs, with no AE beyond grade 3 observed. CONCLUSION: Lenvatinib RFA sequential therapy might offer favorable tolerability and potential prognostic improvement compared to lenvatinib monotherapy.
RESUMO
BACKGROUND: The global phase 3 NAPOLI -1 trial of patients with pancreatic ductal adenocarcinoma (PDAC) demonstrated an overall survival (OS) benefit from using liposomal irinotecan and 5-fluorouracil/leucovorin (nal-IRI + 5-FU/LV) after treatment with gemcitabine (GEM) compared to 5-FU/LV alone. However, the efficacy and safety of this regimen in older patients are not well studied. METHODS: We conducted a single-center retrospective study to compare the therapeutic efficacy of nal-IRI + 5-FU/LV between older and younger patients with cutoff ages of 70 and 75 years, respectively. We included patients with a prior history of one or more GEM-based regimens for locally advanced or metastatic PDAC and were treated with nal-IRI + 5-FU/LV. RESULTS: Of the 115 patients, 54 (47.0%) and 24 (20.9%) were aged ≥ 70 and ≥ 75 years, respectively. The median OS and progression-free survival (PFS) of the entire cohort were 8.5 and 3.6 months, respectively. No significant differences were observed in OS and PFS hazard ratios using age cutoffs of 70 (P = 0.90 and 0.99, respectively) and 75 (P = 0.90 and 0.76, respectively) years. Additionally, no significant differences were found in the incidence of treatment-related adverse events (trAEs) between patients aged ≥ 70 and < 70 years or those aged ≥ 75 and < 75 years. Other than hematological toxicity, no trAEs higher than Grade 4 were observed in either age group. CONCLUSION: The efficacy and safety of nal-IRI + 5-FU/LV for patients with PDAC are not significantly different for those aged ≥ 70 years compared to younger patients.

BACKGROUND: Immune checkpoint inhibitors (ICIs) are effective for advanced hepatocellular carcinoma (HCC). However, there are few reports on the correlation between the clinical efficacy of ICIs and the development of immune-related adverse events (irAEs) in patients with HCC. The aim of this study was to investigate the association between irAE development and survival in patients with HCC treated with atezolizumab plus bevacizumab. PATIENTS AND METHODS: We enrolled 150 patients with advanced HCC treated with atezolizumab plus bevacizumab between October 2020 and October 2021 at 5 territorial institutions. We compared the efficacy of atezolizumab plus bevacizumab between patients who experienced irAEs (irAE group) and those who did not (non-irAE group). RESULTS: Thirty-two patients (21.3%) developed irAEs of any grade. Grade 3/4 irAEs were observed in 9 patients (6.0%). The median progression-free survivals (PFS) in the irAE and non-irAE groups were 273 and 189 days, respectively (P = .055). The median overall survivals (OS) in the irAE and non-irAE groups were not reached and 458 days, respectively (P = .036). Grade 1/2 irAEs significantly prolonged PFS (P = .014) and OS (P = .003). Grade 1/2 irAEs were significantly associated with PFS (hazard ratio [HR], 0.339; 95% confidence interval [CI], 0.166-0.691; P = .003) and OS (HR, 0.086; 95% CI, 0.012-0.641; P = .017) on multivariate analysis. CONCLUSION: The development of irAEs was associated with increased survival in a real-world population of patients with advanced HCC treated with atezolizumab plus bevacizumab. Grade 1/2 irAEs were strongly correlated with PFS and OS.

BACKGROUND: Fluorouracil, leucovorin (5FU/LV), and nanoliposomal-irinotecan (nal-IRI) combination therapy has been established as the second-line treatment for advanced pancreatic ductal adenocarcinoma. Oxaliplatin with 5FU/LV (FOLFOX) is often used as a subsequent treatment, although its efficacy and safety are yet to be fully elucidated. We aimed to evaluate the efficacy and safety of FOLFOX as a third- or later-line treatment for patients with advanced pancreatic ductal adenocarcinoma. METHODS: We conducted a single-centre, retrospective study that enrolled 43 patients who received FOLFOX after failure of gemcitabine-based regimen followed by 5FU/LV + nal-IRI therapy between October 2020 and January 2022. FOLFOX therapy consisted of oxaliplatin (85 mg/m2), levo-leucovorin calcium (200 mg/m2) and 5-FU (2400 mg/m2) every 2 weeks per cycle. Overall survival, progression-free survival, objective response, and adverse events were evaluated. RESULTS: At the median follow-up time of 3.9 months in all patients, the median overall survival and progression-free survival were 3.9 months (95% confidence interval [CI], 3.1-4.8) and 1.3 months (95% CI, 1.0-1.5), respectively. Response and disease control rates were 0 and 25.6%, respectively. The most common adverse event was anaemia in all grades followed by anorexia; the incidence of anorexia and grades 3 and 4 was 21 and 4.7%, respectively. Notably, grades 3-4 peripheral sensory neuropathy was not observed. Multivariable analysis revealed that a C-reactive protein (CRP) level of > 1.0 mg/dL was a poor prognostic factor for both progression-free survival and overall survival: hazard ratios were 2.037 (95% CI, 1.010-4.107; p = 0.047) and 2.471 (95% CI, 1.063-5.745; p = 0.036), respectively. CONCLUSION: FOLFOX as a subsequent treatment after failure of second-line treatment with 5FU/LV + nal-IRI is tolerable, although its efficacy is limited, particularly in patients with high CRP levels.

AIM: Cabozantinib showed a favorable benefit-risk profile in Japanese patients with advanced hepatocellular carcinoma (HCC) in an open-label, phase II study (NCT03586973). This analysis presents cumulative data to final database lock. METHODS: Patients with previously treated, advanced HCC received cabozantinib 60 mg/day. Progression-free survival (PFS) and tumor response rates in prior-sorafenib and sorafenib-naïve cohorts were assessed by independent radiology committee (IRC) and an investigator. Liver function was evaluated by albumin-bilirubin (ALBI) score. RESULTS: Median cabozantinib exposure was 5.6 months. In the prior-sorafenib cohort (n = 20), median PFS was 7.4 months per IRC assessment and 5.6 months per investigator assessment. In the sorafenib-naïve cohort (n = 14), median PFS was 3.6 and 4.4 months per IRC and investigator assessment, respectively. Six-month PFS rate per IRC and investigator assessment in the prior-sorafenib cohort was 59.8% and 49.5%, respectively, and in the sorafenib-naïve cohort was 16.7% and 35.7%, respectively. Disease control rate by both IRC and investigator assessment was 85.0% in the prior-sorafenib cohort and 64.3% in the sorafenib-naïve cohort. Median overall survival (Kaplan-Meier estimate) was 19.3 and 9.9 months in the prior-sorafenib and sorafenib-naïve cohort, respectively. Mean ALBI score remained relatively constant in patients able to continue treatment. The most frequent adverse events were palmar-plantar erythrodysesthesia syndrome, diarrhea, hypertension, and decreased appetite. No new safety concerns were identified. CONCLUSIONS: Cabozantinib showed efficacy and a manageable safety profile in Japanese patients with advanced HCC.
RESUMO
BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers, and surgical resection is the only potentially curative approach. However, the rate of recurrence remains high, particularly within the first 6 months, and is associated with a poor prognosis. The present study evaluated the clinical characteristics and risk factors for early recurrence in pancreatic ductal adenocarcinoma (PDAC) patients who underwent curative resection, regardless of the use of neoadjuvant chemotherapy, to identify predictive factors associated with early recurrence and poor outcomes as well as to determine the optimal treatment strategy for patients at high risk of early recurrence after surgical resection. METHODS: Patients who underwent pancreatic resection for PDAC at our institution from 2013 to 2021 were included in this study. We investigated the clinicopathological features of patients in groups: those with recurrence within 6 months, recurrence between 6 and 12 months, and recurrence beyond 12 months or no recurrence. A logistic regression analysis identified covariates associated with early recurrence at 6 and 12 months. RESULTS: The study included 403 patients with a median follow-up of 25.7 months. Recurrence was observed in 279 patients, with 14.6% recurring within 6 months, 23.3% within 6-12 months, and 62% after 12 months or not at all. The preoperative CA19-9 level, modified Glasgow prognostic score (mGPS), and positive peritoneal cytology were significant risk factors for early recurrence within 6 months, while positive peritoneal cytology, lymph node metastasis, and the absence of adjuvant chemotherapy were significant risk factors for recurrence within 12 months. For patients who received preoperative chemotherapy or chemoradiotherapy, the preoperative CA19-9 level, mGPS, and positive peritoneal cytology were significant independent risk factors for early recurrence within 6 months, while positive peritoneal cytology, lymph node metastasis, and the absence of adjuvant chemotherapy were significant independent risk factors for recurrence within 12 months. The study concluded that the overall survival after surgical resection for potentially resectable PDAC worsened according to the number of risk factors present in the patient. CONCLUSIONS: We clarified that preoperative CA19-9, positive peritoneal cytology, and the lack of adjuvant chemotherapy were consistent predictors for early recurrence within 6 and 12 months. In addition, an increased number of risk factors affecting the patient was associated with a poorer overall survival after potentially curable resection. Calculating the number of risk factors for early recurrence may be an essential predictive factor when considering treatment strategies.

BACKGROUND: Transarterial chemoembolization (TACE) is the standard treatment for intermediate stage hepatocellular carcinoma (HCC) (Barcelona Clinic Liver Cancer [BCLC] B). However, it often leads to a poor prognosis and decreased hepatic function especially in patients with BCLC substage B2. Lenvatinib (LEN) was demonstrated to be efficacious in these patients in the REFLECT phase 3 trial. We therefore aimed to evaluate the efficacy and safety of LEN as a first-line treatment for the patients with HCC at BCLC substage B2. METHODS: This prospective observational study used LEN in TACE-naïve patients with HCC at BCLC substage B2 and preserved hepatic function. The primary endpoint was overall survival. A one-year survival rate threshold of 60% and an expected survival rate of 78%, based on previous reports of TACE, was assumed for setting the sample size. With a one-sided α-type error of 5% and 70% detection power, 25 patients were required over a 2-year enrollment period and 10-month follow-up period. RESULTS: Thirty-one patients were enrolled in this study from June 2018 to June 2020. The 1-year survival rate was 71.0% (90% confidence interval, 68.4-73.6%). Median overall and progression-free survival periods were 17.0 and 10.4 months, and the objective response rates according to Response Evaluation Criteria in Solid Tumor (RECIST) version 1.1 and modified RECIST criteria were 22.6% and 70.0%, respectively. Common adverse events (AEs) were fatigue (68%), hypertension (65%), anorexia (61%), palmar-plantar erythrodysesthesia (39%), and thrombocytopenia (32%) of any grade; aspartate aminotransferase increased (23%), alanine aminotransferase increased (16%), and grade ≥ 3 proteinuria (13%). Treatment interruption and dose reduction were required in 61% and 81% of patients, respectively. LEN was discontinued in 29 patients due to disease progression (n = 17), AEs (n = 9), conversion to curative treatments (n = 2), and sudden death (n = 1), whereas post-LEN treatments were administered in 18 patients, including systemic chemotherapy (n = 11), TACE (n = 6), transarterial infusion (n = 1) and clinical trial (n = 1). CONCLUSIONS: The results suggest that LEN provides treatment benefits as an initial therapeutic in patients with BCLC substage B2 HCC with a safety profile comparable to that previously reported.

BACKGROUND: The preferred regimen for unresectable pancreatic cancer following gemcitabine-based chemotherapy is not well-established. This study compared the efficacy of (â °) liposomal irinotecan (nal-IRI) plus 5-fluorouracil (5-FU)/leucovorin (LV) (nal-IRI/5-FU/LV) versus modified FOLFIRINOX (mFFX) and (â ±) nal-IRI/5-FU/LV versus FOLFIRI, respectively, and the safety of the three regimens each other, as second-line chemotherapies for unresectable pancreatic cancer. METHODS: This was a retrospective single-center analysis of all patients who were administered nal-IRI/5-FU/LV, mFFX, or FOLFIRI from December 2014 to July 2021 as second-line chemotherapy for pancreatic cancer. The primary endpoint was the overall survival (OS) of all patients, excluding those with locally advanced pancreatic cancer. Regarding safety, we assessed the incidence of grade ≥3 adverse events of interest in all patients. RESULTS: A total of 137 patients (nal-IRI/5-FU/LV, n = 55; mFFX, n = 39; FOLFIRI, n = 43) were included. The median OS in the nal-IRI/5-FU/LV group, the mFFX group, and the FOLFIRI group was 7.4, 11.8, and 8.4 months, respectively. Compared with the nal-IRI/5-FU/LV group, the mFFX and FOLFIRI groups displayed a hazard ratio of 0.66 [95% confidence interval 0.40-1.08] and 0.87 [95% confidence interval 0.55-1.39], respectively. In the FOLFIRI group, the incidence of grade ≥3 treatment-related adverse events tended to be low among all three groups. CONCLUSIONS: Given the trend toward longer OS in the mFFX group and the lower incidence of adverse events in the FOLFIRI group, both mFFX and FOLFIRI, as well as nal-IRI/5-FU/LV, can be treatment options for second-line chemotherapy for unresectable pancreatic cancer.

BACKGROUND: Pancreatic cancer is often associated with cachexia. It had been reported that eicosapentaenoic acid (EPA) improve cachexia. This study aimed to evaluate the efficacy and safety of gemcitabine with an EPA-enriched oral supplement in patients with advanced pancreatic cancer. METHODS: This open-label phase II study consisted of patients (pts) who were randomly categorized into the EPA group (1,000 mg/m2 gemcitabine was administered on day 1, 8, and 15, every 4 weeks while an EPA-enriched oral supplement (prosure®, EPA 1.056 mg per pack) was taken daily at the maximum of two packs or the gemcitabine monotherapy group with an allocation ratio of 2:1. The primary endpoint was the evaluation of the 1-year survival estimating 10% addition. RESULTS: Randomized 68 pts were examined (EPA: 45, gemcitabine: 23). The 1-year survival probability of the EPA group was 35% while the gemcitabine group was 19%. The median survival times were 8.2 and 9.7 mo, respectively. The hazard ratio for EPA group was 0.79 [95% CI 0.46-1.37]; (P = 0.40). The toxicities were mild and insignificant in both groups. More beneficial effects of EPA in survival were observed in men, pancreatic body-tail and low C-reactive protein patients. CONCLUSION: An EPA-enriched oral supplement may be effective in advanced pancreatic cancer.

PURPOSE: To assess the impact of clinical factors on the safety and efficacy of atezolizumab plus bevacizumab (ATZ + BV) treatment in patients with unresectable hepatocellular carcinoma (u-HCC). METHOD: Ninety-four u-HCC patients who were treated with ATZ + BV at multiple centers were enrolled. We defined Child-Pugh (CP)-A patients who received ATZ + BV treatment as a first line therapy as the 'meets the broad sense of the IMbrave150 criteria' group (B-IMbrave150-in, n = 46), and patients who received ATZ + BV treatment as a later line therapy or CP-B patients (regardless of whether ATZ + BV was a first line or later line therapy) as the B-IMbrave150-out group (n = 48). Patients were retrospectively analyzed for adverse events (AEs) and treatment outcomes according to their clinical characteristics, including neutrophil lymphocyte ratio (NLR) at baseline. RESULTS: The overall incidence of AEs was 87.2% (82/94 patients). The frequency of interruption of ATZ + BV treatment due to fatigue was higher in CP-B than CP-A patients (p = 0.030). Objective response (OR) rates of the B-IMbrave150-in group (28.3%, 39.1%) were significantly higher than those of the B-IMbrave150-out group (8.3%, 18.8%; p = 0.0157, 0.0401) using Response Evaluation Criteria in Solid Tumors (RECIST) and modified RECIST, respectively. In multivariate analysis, NLR (hazard ratio (HR), 4.591; p = 0.0160) and B-IMbrave150 criteria (HR, 4.108; p = 0.0261) were independent factors associated with the OR of ATZ + BV treatment using RECIST. CONCLUSION: In real-world practice, ATZ + BV treatment might offer significant benefits in patients who meet B-IMbrave150 criteria or have low NLR.
RESUMO
INTRODUCTION: Postoperative pancreatic fistula (POPF) is one of the major critical complications after pancreatic resection. Recently, postoperative acute pancreatitis (POAP), a new concept for a pancreatic-specific complication following pancreatic resection, has been advocated, and its association with POPF has been reported. The present study examined the clinical features of POAP and identified the associations of POAP with POPF and other postoperative morbidities in pancreatic ductal adenocarcinoma (PDAC) patients undergoing pancreatic resection. METHODS: A total of 312 consecutive patients who underwent pancreatic resection for PDAC at our institution from 2013 to 2019 were enrolled in this study. POAP was defined as an elevated serum amylase level above the upper limit normal on postoperative day (POD) 0 or 1, based on Connor's definition. The severity of POPF was assessed by the International Study Group on Pancreatic Surgery definition. RESULTS: A total of 184 patients (58.9%) had POAP. POAP occurred in 58.5% of subtotal stomach-preserving pancreatoduodenectomy patients and 60% of distal pancreatectomy combined with splenectomy patients. The presence of POAP was significantly associated with the development of clinically relevant POPF, higher rates of severe morbidity, and a prolonged hospital stay after pancreatic resection. A multivariate analysis showed that the presence of POAP and elevated C-reactive protein levels on POD 3 were independent predictors of clinically relevant POPF after subtotal stomach-preserving pancreatoduodenectomy. CONCLUSIONS: POAP is associated with the development of POPF, higher rates of severe morbidity, and a prolonged hospital stay after pancreatic resection and is an independent risk factor for clinically relevant POPF after pancreatoduodenectomy. POAP represents an important indicator for planning treatment strategies to prevent serious complications, including POPF.

Pancreatic cancer frequently involves cancer-associated thromboembolism, which is strongly associated with poor prognosis. Tissue factor, a blood coagulation factor largely produced in cancer patients as a component of extracellular vesicles, plays a key role in the incidence of cancer-associated thromboembolism in patients with pancreatic cancer. However, no prospective studies have been published on the relationship between tissue factor and cancer-associated thromboembolism or patient clinical characteristics, including recent chemotherapy regimens. Thus, we aimed to address this in a Japanese cohort of 197 patients and 41 healthy volunteers. Plasma tissue factor levels were measured by ELISAs preevaluated by tissue factor specificity. Multivariable analysis was used to identify independent predictors of cancer-associated thromboembolism. We found that the cancer-associated thromboembolism rate in the patient cohort was 6.6% (4.6%, venous thromboembolism; 2.0%, arterial thromboembolism). Tissue factor levels of 100 pg/mL or higher at patient registration were predictive of cancer-associated thromboembolism, with positive and negative predictive values of 23.1% and 94.6%, respectively. Multivariable analysis showed that plasma tissue factor levels were an independent predictive factor for cancer-associated thromboembolism, with a risk ratio of 5.54 (95% confidence interval, 1.02-30.09). Unlike in healthy volunteers and patients without cancer-associated thromboembolism, tissue factor levels were highly correlated with extracellular vesicles' procoagulant activity in patients developing cancer-associated thromboembolism. Taken together, our data show that the tissue factor levels at patient registration were a predictive factor for cancer-associated thromboembolism in this cohort of patients with pancreatic cancer.

LESSONS LEARNED: Axitinib exhibited marginal activity against gemcitabine-refractory unselected biliary tract cancer. Pretreated soluble vascular endothelial growth factor receptor-2 may be a useful biomarker for axitinib treatment outcome. Ascites should be carefully monitored in patients receiving anti-vascular endothelial growth factor receptor therapy including axitinib in advanced biliary tract cancer. BACKGROUND: There are no clear options for second-line treatment in patients with gemcitabine (GEM)-refractory biliary tract cancer (BTC). We conducted a multicenter, single-arm, phase II trial to confirm the efficacy and safety of axitinib, a potent selective inhibitor of vascular endothelial growth factor receptor (VEGFR)-1/2/3, in patients with GEM-refractory BTC. METHODS: Patients refractory or intolerant to GEM-based chemotherapy were enrolled. Axitinib was administered orally at an initial dose of 5 mg twice daily. The primary endpoint was progression-free survival (PFS), and the threshold and expected values were set at 2 and 3 months, respectively. The target sample size was 32 patients. RESULTS: Nineteen patients were enrolled. The trial was interrupted for a total of 13 months for the evaluation of adverse events. Thirteen patients were previously treated with ≥2 regimens. The median PFS was 2.8 months (95% confidence interval [CI]: 2.1-4.1). The median overall survival was 5.8 months (95% CI: 3.3-9.7). The response rate was 5.3% (95% CI: 0.0-15.3). Grade 3 ascites occurred in two patients. Baseline soluble VEGFR-2 levels were significantly associated with PFS. CONCLUSION: Axitinib exhibited marginal activity against GEM-refractory BTC. Ascites should be carefully monitored in axitinib-treated patients with advanced BTC.

BACKGROUND: Malignant gastric outlet obstruction (MGOO) occasionally occurs due to pancreaticobiliary cancer. Endoscopic duodenal stenting (DS) is a common treatment for MGOO. However, it has been reported that DS does not have sufficient patency time for it to be used in patients who have a potentially increased lifespan. Nowadays, systemic chemotherapy for pancreaticobiliary cancer has developed, and its anti-tumour effect would make time to stent dysfunction longer. Therefore, we retrospectively evaluated the association between objective response to systemic chemotherapy, followed by DS and time to stent dysfunction in patients with advanced pancreaticobiliary cancer. METHODS: This retrospective study included 109 patients with advanced pancreaticobiliary cancer who received systemic chemotherapy after DS. Patients who showed complete or partial response were defined as responders. The rest were defined as non-responders. Time to stent dysfunction was compared between responders and non-responders using the landmark analysis at 2 months after DS. Death without recurrence of MGOO was considered as a competing risk for time to stent dysfunction. RESULTS: Combination and monotherapy regimens were adopted for 46 and 63 patients, respectively. Median progression-free survival and overall survival were 3.2 months (95% confidence interval [CI], 2.4-4.0) and 6.0 months (95% CI, 4.6-7.3). Objective response was observed in 21 patients (19.3%). Median time to stent dysfunction was 12.5 months (95% CI, 8.4-16.5) in the entire cohort. In 89 patients, responders had a lower cumulative incidence of stent dysfunction than non-responders: 9.5 and 19.1% at 6 months, and 19.0 and 27.9% at 1-year, respectively. There was difference of time to stent dysfunction between responders and non-responders among patients who received combination regimen as the first-line treatment with p-value of 0.009: cumulative incidence was 0 and 42.9% at 6 months, and 9.3 and 57.1% at 1-year, respectively. CONCLUSIONS: Longer time to stent dysfunction is expected when systemic chemotherapy following DS suppresses tumour progression; DS is slated to be a standard treatment for MGOO even in patients with pancreaticobiliary cancer and a long lifespan.

AIMS: To assess the safety, efficacy, and prognostic impact of clinical factors associated with lenvatinib treatment in highly advanced hepatocellular carcinoma (HCC) with tumor thrombus in the main portal vein trunk (VP4) or tumor with more than 50% liver occupation (tm50%LO). METHODS: A total of 61 highly advanced HCC patients (41 patients with tm50%LO and 20 patients with VP4) who were treated with lenvatinib at multicenter were enrolled and retrospectively analyzed for treatment outcomes according to their clinical status, including tumor morphology. RESULTS: The most frequent grade ≥3 adverse event in tm50%LO HCC was elevated aspartate aminotransferase (17.1%). Objective response rates were 37.5% and 0% in tm50%LO HCC patients with Child-Pugh grade (CP)-A and CP-B, respectively, and 26.7% and 0% in VP4 HCC patients with CP-A and CP-B, respectively. Estimated median progression-free survival and overall survival were 132 days and 229 days, and 101 days and 201 days in patients with tm50%LO and VP4, respectively. In multivariate analysis, modified albumin-bilirubin grade (hazard ratio 0.372, 95% CI 0.157-0.887; p = 0.0241) and tumor morphology (hazard ratio 0.322, 95% CI 0.116-0.889; p = 0.0287) were independently associated with progression-free survival in patients with tm50%LO HCC. In VP4 HCC, median progression-free survival was worse in CP-B (57 days) than in CP-A patients (137 days, p = 0.0462). CONCLUSIONS: Lenvatinib treatment offers a benefit in highly advanced HCC (tm50%LO or VP4) patients with good liver function or nodular-type tumor. The various characteristics identified in this study might be useful as indicators of lenvatinib treatment in highly advanced HCC with tm50%LO or VP4, which are considered very refractory cancers.
RESUMO
BACKGROUND/AIMS: Lusutrombopag, a small-molecule thrombopoietin receptor agonist, is used to treat thrombocytopenia based on the results of a phase 3 trial, including data for single-use administration in patients with chronic liver disease (CLD) undergoing invasive procedures. We aimed to evaluate the efficacy and safety of repeated lusutrombopag use. METHODS: Lusutrombopag was administered repeatedly in patients undergoing multi-cycle invasive procedures at intervals >1 month. RESULTS: Data from 8 patients (median platelet count at baseline, 44.0 [range, 35-49] × 109/L) and 25 cycles of invasive procedures, including 2 cycles in 3 patients, 3 cycles in 4 patients, and 7 cycles in 1 patient, were retrospectively evaluated. The procedures included 18 transarterial chemoembolizations, 5 radiofrequency ablations, and 2 liver needle biopsies. Platelet counts increased significantly compared with baseline, and median changes in platelet counts were 46.0 × 109/L (p = 0.012) in cycle 1, 44.0 × 109/L (p = 0.012) in cycle 2, and 42.0 × 109/L (p = 0.008) in cycles 3-7. No severe adverse events, including portal vein thrombus or bleeding, were observed. CONCLUSIONS: Repeated use of lusutrombopag might be safe and effective against thrombocytopenia in patients with CLD undergoing multi-cycle invasive procedures, although long-term data from more patients are required.

A previous randomized phase 2 study of hepatocellular carcinoma revealed that the c-Met inhibitor tivantinib as second-line treatment significantly prolonged progression-free survival in a subpopulation whose tumor samples highly expressed c-Met (MET-high). Accordingly, this phase 3 study was conducted to evaluate the efficacy of tivantinib as a second-line treatment for Japanese patients with MET-high hepatocellular carcinoma. This randomized, double-blind, placebo-controlled study was conducted at 60 centers in Japan. Hepatocellular carcinoma patients with one prior sorafenib treatment and those with MET-high tumor samples were eligible for inclusion. Registered patients were randomly assigned to either the tivantinib or placebo group at a 2:1 ratio and were treated with twice-a-day oral tivantinib (120 mg bid) or placebo until the discontinuation criteria were met. The primary endpoint was progression-free survival while the secondary endpoints included overall survival and safety. Between January 2014 and June 2016, 386 patients provided consent, and 195 patients were randomized to the tivantinib (n = 134) or placebo (n = 61) group. Median progression-free survival was 2.8 (95% confidence interval: 2.7-2.9) and 2.3 (1.5-2.8) mo in the tivantinib and placebo groups, respectively (hazard ratio = 0.74, 95% confidence interval: 0.52-1.04, P = .082). Median overall survival was 10.3 (95% confidence interval: 8.1-11.6) and 8.5 (6.2-11.4) mo in the tivantinib and placebo group, respectively (hazard ratio = 0.82, 95% confidence interval: 0.58-1.15). The most common tivantinib-related grade ≥3 adverse events were neutropenia (31.6%), leukocytopenia (24.8%), and anemia (12.0%). This study did not confirm the significant efficacy of tivantinib as a second-line treatment for Japanese patients with MET-high hepatocellular carcinoma. (NCT02029157).

BACKGROUND & AIMS: Limited data on treatment of elderly patients with hepatocellular carcinoma (HCC) increase the unmet need. REACH and REACH-2 were global phase III studies of ramucirumab in patients with HCC after prior sorafenib, where patients with alpha-fetoprotein (AFP) ≥400 ng/mL showed an overall ssurvival (OS) benefit for ramucirumab. These post-hoc analyses examined efficacy and safety of ramucirumab in patients with HCC and baseline AFP ≥ 400 ng/mL by three prespecified age subgroups (<65, ≥65 to <75 and ≥75 years). METHODS: Individual patient data were pooled from REACH (baseline AFP ≥400 ng/mL) and REACH-2. Kaplan-Meier and Cox proportional hazards regression methods (stratified by study) assessed OS, progression-free survival (PFS), time to progression (TTP) and patient-reported outcomes (Functional Hepatobiliary System Index-8 [FHSI-8] score). RESULTS: A total of 542 patients (<65 years: n = 302; ≥65 to <75 years: n = 160; ≥75 years: n = 80) showed similar baseline characteristics between ramucirumab and placebo. Older subgroups had higher hepatitis C and steatohepatitis incidences, and lower AFP levels, than the <65 years subgroup. Ramucirumab prolonged OS in patients <65 years (hazard ratio [HR], 0.753; 95% CI 0.581-0.975), ≥65 to <75 years (0.602; 0.419-0.866) and ≥75 years (0.709; 0.420-1.199), PFS and TTP irrespective of age. Ramucirumab showed similar overall safety profiles across subgroups, with a consistent median relative dose intensity ≥97.8%. A trend towards a delay in symptom deterioration in FHSI-8 with ramucirumab was observed in all subgroups. CONCLUSIONS: In this post-hoc analysis, ramucirumab showed a survival benefit across age subgroups with a tolerable safety profile, supporting its use in advanced HCC with elevated AFP, irrespective of age, including ≥75 years.

BACKGROUND: Patients with advanced hepatocellular carcinoma and increased α-fetoprotein concentrations have poor prognosis. We aimed to establish the efficacy of ramucirumab in patients with advanced hepatocellular carcinoma and α-fetoprotein concentrations of 400 ng/mL or higher. METHODS: REACH-2 was a randomised, double-blind, placebo-controlled, phase 3 trial done at 92 hospitals, clinics, and medical centres in 20 countries. Eligible patients were aged 18 years or older and had histologically or cytologically confirmed hepatocellular carcinoma, or diagnosed cirrhosis and hepatocellular carcinoma, Barcelona Clinic Liver Cancer stage B or C disease, Child-Pugh class A liver disease, Eastern Cooperative Oncology Group (ECOG) performance statuses of 0 or 1, α-fetoprotein concentrations of 400 ng/mL or greater, and had previously received first-line sorafenib. Participants were randomly assigned (2:1) via an interactive web response system with a computer-generated random sequence to 8 mg/kg intravenous ramucirumab every 2 weeks or placebo. All patients received best supportive care. The primary endpoint was overall survival. Secondary endpoints were progression-free survival, proportion of patients achieving an objective response, time to radiographic progression, safety, time to deterioration in scores on the Functional Assessment of Cancer Therapy Hepatobiliary Symptom Index 8 (FHSI-8), and time to deterioration in ECOG performance status. We also pooled individual patient data from REACH-2 with data from REACH (NCT01140347) for patients with α-fetoprotein concentrations of 400 ng/mL or greater. Efficacy analyses were by intention to treat, whereas safety analyses were done in all patients who received at least one dose of study drug. This trial is registered with ClinicalTrials.gov, number NCT02435433. FINDINGS: Between July 26, 2015, and Aug 30, 2017, 292 patients were randomly assigned, 197 to the ramucirumab group and 95 to the placebo group. At a median follow-up of 7·6 months (IQR 4·0-12·5), median overall survival (8·5 months [95% CI 7·0-10·6] vs 7·3 months [5·4-9·1]; hazard ratio [HR] 0·710 [95% CI 0·531-0·949]; p=0·0199) and progression-free survival (2·8 months [2·8-4·1] vs 1·6 months [1·5-2·7]; 0·452 [0·339-0·603]; p<0·0001) were significantly improved in the ramucirumab group compared with the placebo group. The proportion of patients with an objective response did not differ significantly between groups (nine [5%] of 197 vs one [1%] of 95; p=0·1697). Median time to deterioration in FHSI-8 total scores (3·7 months [95% CI 2·8-4·4] vs 2·8 months [1·6-2·9]; HR 0·799 [95% CI 0·545-1·171]; p=0·238) and ECOG performance statuses (HR 1·082 [95% CI 0·639-1·832]; p=0·77) did not differ between groups. Grade 3 or worse treatment-emergent adverse events that occurred in at least 5% of patients in either group were hypertension (25 [13%] in the ramucirumab group vs five [5%] in the placebo group), hyponatraemia (11 [6%] vs 0) and increased aspartate aminotransferase (six [3%] vs five [5%]). Serious adverse events of any grade and cause occurred in 68 (35%) patients in the ramucirumab group and 28 (29%) patients in the placebo group. Three patients in the ramucirumab group died from treatment-emergent adverse events that were judged to be related to study treatment (one had acute kidney injury, one had hepatorenal syndrome, and one had renal failure). INTERPRETATION: REACH-2 met its primary endpoint, showing improved overall survival for ramucirumab compared with placebo in patients with hepatocellular carcinoma and α-fetoprotein concentrations of at least 400 ng/mL who had previously received sorafenib. Ramucirumab was well tolerated, with a manageable safety profile. To our knowledge, REACH-2 is the first positive phase 3 trial done in a biomarker-selected patient population with hepatocellular carcinoma. FUNDING: Eli Lilly.
