Background: The post-insertion clinical course of esophageal self-expandable metal stents (SEMS) in initially frail patients with esophageal carcinoma (EC) with dysphagia remains unclear. This study aimed to assess dysphagia improvement and evaluate prognosis in initially frail patients with advanced EC following SEMS insertion. Methods: We retrospectively reviewed EC patients with EC who underwent esophageal SEMS insertion at our institution between January 2014 and March 2023. Inclusion criteria comprised Eastern Cooperative Oncology Group Performance Status (ECOG PS) ≥ 3 or ECOG PS 2 for individuals aged ≥ 75 years and recommendation for best supportive care by a multidisciplinary team. Results: Forty-six patients met the inclusion criteria. Among them, 37 patients (80.4%) were ≥ 75 years old, and 21 patients (45.7%) exhibited ECOG PS 3 or 4. Dysphagia score (DS) ≥ 3 was observed in 27 patients (58.7%). All esophageal SEMS insertions were successfully completed. Post-procedure, there were two fatal cases of aspiration pneumonia and one perforation incident. DS improved to ≤ 1 in 25 patients (54.3%), with multivariate analysis indicating DS 3–4 and Glasgow Prognostic Score (GPS) 1–2 as negative predictive factors. The median overall survival was 4.1 months (95% confidence interval 1.8–6.5). Conclusions: Esophageal SEMS insertion effectively alleviated dysphagia in initially frail EC patients, yet prognosis remained poor, with occurrences of some fatal adverse events. Careful selection of candidates for esophageal SEMS insertions is crucial in this demographic, particularly considering the challenges in improving dysphagia for patients with DS 3–4 and GPS 1–2.

Introduction: Hepatic arterial infusion chemotherapy (HAIC) with cisplatin and lenvatinib exhibits strong antitumor effects against advanced hepatocellular carcinoma (HCC). Higher antitumor activity is expected for the combination treatment. The aim of this trial was to evaluate the efficacy and safety of lenvatinib in combination with HAIC using cisplatin in patients with advanced HCC. Methods: In this multicenter, open-labeled, single-arm, phase II trial, patients with advanced HCC categorized as Child-Pugh class A with no prior history of systemic therapy were enrolled. Patients received lenvatinib plus HAIC with cisplatin (lenvatinib: 12 mg once daily for patients ≥60 kg, 8 mg once daily for patients <60 kg; HAIC with cisplatin: 65 mg/m2, day 1, every 4–6 weeks, maximum of six cycles). The primary endpoint was the objective response rate (ORR) assessed using modified RECIST by the Independent Review Committee. The secondary endpoints were the ORR assessed using RECIST v1.1, progression-free survival, overall survival, and frequency of adverse events associated with the treatment. Results: A total of 36 patients were enrolled between September 2018 and March 2020. In the 34 evaluable patients, the ORR assessed by the Independent Review Committee using modified RECIST and RECIST v1.1 were 64.7% (95% confidence interval [CI]: 46.5–80.3%) and 45.7% (95% CI: 28.8–63.4%), respectively. The median progression-free survival and overall survival were 6.3 months (95% CI: 5.1–7.9 months) and 17.2 months (95% CI: 10.9 – not available, months), respectively. The main grade 3–4 adverse events were increased aspartate aminotransferase (34%), leukopenia (22%), increased alanine aminotransferase (19%), and hypertension (11%). Conclusion: Lenvatinib plus HAIC with cisplatin yielded a favorable ORR and overall survival and was well tolerated in patients with advanced HCC. Further evaluation of this regimen in a phase III trial is warranted. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the efficacy and safety of nanvuranlat [an L-type amino acid transporter 1 inhibitor] monotherapy as a later-line treatment in advanced, metastatic, and refractory biliary tract cancers., Patients and Methods: A multicenter, randomized, double-blind, placebo-controlled phase II study was conducted across fourteen leading Japanese cancer centers and hospitals. Nanvuranlat 25 mg/m2/day or placebo was given intravenously in cycles of 5 consecutive days, followed by 9 days off. The primary endpoint was progression-free survival (PFS). Secondary endpoints included overall survival and disease control rate. Subgroup analysis was performed in patients with high L-type amino acid transporter 1 expression and biliary tract cancer subtypes., Results: A total of 211 patients were screened, of which 105 eligible patients were randomized. Among these, 70 received nanvuranlat and 35 received placebo. Nanvuranlat demonstrated an improvement in PFS when compared with placebo (HR, 0.56; 95% confidence interval, 0.34-0.90; P = 0.02). Grade 3 or higher adverse events were reported in 30.0% and 22.9% of those in the nanvuranlat and placebo groups, respectively. The overall survival was not statistically different between nanvuranlat- and placebo-treated patients. An exploratory analysis indicated that nanvuranlat is warranted to evaluate its long-term clinical benefit in patients with intrahepatic cholangiocarcinoma, extrahepatic cholangiocarcinoma, and gallbladder cancer., Conclusions: Compared with placebo, nanvuranlat improved PFS in patients with advanced and refractory biliary tract cancer with an acceptable safety profile. Further studies of this promising compound are warranted in the population of patients who are exhausted from treatment options., (©2024 American Association for Cancer Research.)

Background: The efficacy and safety of conversion surgery (CS) after FOLFIRINOX or gemcitabine plus nab-paclitaxel (GnP) chemotherapy in patients with initially unresectable pancreatic cancer (PC) remains unclear., Methods: This multicenter retrospective cohort study enrolled patients, between 2014 and 2018, with initially locally advanced or metastatic PC who were considered candidates for CS following FOLFIRINOX or GnP chemotherapy. They were classified into surgery (207 patients [194 resection and 13 exploratory laparotomy only]) and continued chemotherapy (10 patients, control) groups. The primary endpoint was overall survival (OS) from the day of diagnosis of potentially curative resection on imaging studies, with an expected hazard ratio (HR) of 0.7., Results: OS in the surgery group was longer than that in the control group (HR, 0.47; 95% confidence interval [CI]: 0.24-0.93). The median OS was 34.4 (95% CI: 27.9-43.4) and 19.8 (95% CI: 14.9-31.1) months in the surgery and control groups, respectively. The Clavien-Dindo grade ≥ IIIa postoperative complication and in-hospital mortality rates were 19.6% and 0.5%, respectively. Multivariate analysis revealed that preoperative chemotherapy duration was not associated with OS., Conclusions: CS, following a favorable response to FOLFIRINOX or GnP chemotherapy, improved initially unresectable PC prognosis (specifically, OS), regardless of the chemotherapy duration., (© 2024 The Author(s).

Pancreatic cancer remains a highly lethal disease with a 5-year survival proportion of <10%. Chemoradiotherapy is a treatment option for unresectable locally advanced (UR-LA) or borderline resectable (BR) pancreatic cancer, but its efficacy is not sufficient. Induction of the synergistic effect of irradiation and immune checkpoint inhibitors can be an attractive strategy. An open-label randomized phase III trial has been conducted since October 2020 to confirm the superiority of nivolumab plus S-1-based chemoradiotherapy over S-1-based chemoradiotherapy alone in patients with UR-LA or BR pancreatic cancer. A total of 216 patients will be enrolled in 14 institutions within 3.5 years. The primary endpoint of the safety run-in part is dose-limiting toxicity, and that of the phase III part is overall survival. This trial was registered at the Japan Registry of Clinical Trials as jRCT2080225361 (https://jrct.niph.go.jp/latest-detail/jRCT2080225361)., (© The Author(s) 2024.

What Is This Summary About?: This summary describes the results from a phase 2 study called FOENIXCCA2. The study evaluated treatment with futibatinib in people with a rare form of advanced bile duct cancer called intrahepatic cholangiocarcinoma (or iCCA), where the tumors have changes in the structure of a gene called FGFR2. These changes include FGFR2 gene fusions. Bile duct cancer often returns after surgery or cannot be treated by surgery because the tumor has spread, so it requires treatment with chemotherapy. People live for a median of 1 year after their first chemotherapy treatment and 6 months after their second treatment. This study included people whose cancer had grown/spread after one or more chemotherapy treatments. The aims of the study were to see if futibatinib could shrink the size of tumors and stop the cancer from growing/spreading and to see how long people lived when treated with futibatinib. Clinicians also looked at side effects from taking futibatinib and at how it affected people's quality of life., What Were the Results?: Futibatinib treatment shrank tumors in over 80% of people who received treatment. Tumors shrank by at least 30% in 42% of people. Futibatinib stopped tumors from growing/spreading for a median of 9.7 months. People who took the medicine lived for a median of 21.7 months, and 72% of people were still alive after 1 year. Side effects from taking futibatinib were like those reported for similar medicines, and clinicians considered the side effects to be manageable by adjusting the dose of futibatinib or treating the side effects. Most people reported that their quality of life stayed the same or improved during the first 9 months of taking futibatinib., What Do the Results Mean?: The results support the use of futibatinib for treating people with advanced bile duct cancer. Based on the results of this study, futibatinib is now approved in the US, Europe, and Japan. Futibatinib is approved for treating adults with advanced bile duct cancer who have received previous treatment for their cancer, and whose tumors have a gene fusion or other change in the FGFR2 gene. Clinical Trial Registration: NCT02052778 (FOENIX-CCA2).

Background and Aims: We compared the safety and efficacy of bintrafusp alfa (BA) in combination with gemcitabine+cisplatin (GemCis), to those of GemCis alone, in patients with biliary tract cancer., Approach and Results: This randomized, double-blind, placebo-controlled, adaptive design phase 2/3 trial (NCT04066491) included adults who are treatment-naive with locally advanced/metastatic biliary tract cancer. Patients (N = 297) were randomized to receive an IV infusion of BA (2400 mg once/3 wk) plus GemCis (gemcitabine 1000 mg/m 2 +cisplatin 25 mg/m 2 on days 1 and 8/3 wk; 8 cycles) (BA group, n = 148) or placebo+GemCis (placebo group, n = 149). The primary end point was overall survival (OS). For adaptation analysis (phase 2-phase 3; data cutoff: May 20, 2021), efficacy was assessed in the first 150 patients who were antibiotic-naive when 80 progression-free survival events had occurred and ≥ 19 weeks of follow-up had been completed (BA, n = 73; placebo, n = 77). Median OS (95% CI) for the BA (11.5 mo [9.3-not estimable]) and placebo (11.5 mo [10.0-not estimable]) groups was comparable (hazard ration 1.23 [95% CI 0.66-2.28]; p = 0.7394); OS data maturity was 27.2% (41 events/151 patients). The most common grade ≥3 treatment-related adverse event was anemia (BA, 26.0%; placebo, 22.8%). Bleeding adverse events were reported more frequently in the BA group (28.8%) versus the placebo group (7.4%). Deaths within 60 days of the first dose were reported in 7.5% and 1.3% of patients in the BA and placebo groups, respectively., Conclusions: BA+GemCis did not provide a clinically meaningful benefit compared with GemCis alone as first-line treatment for biliary tract cancer, and the study was discontinued early (terminated: August 20, 2021)., (Copyright © 2024 The Author(s).

Background: Recent studies suggest that early tumor shrinkage (ETS) and depth of response (DpR) reflect outcomes of chemotherapy in various cancers. This study evaluated the association of ETS and DpR with clinical outcomes using data from JCOG1113, which demonstrated the non-inferiority of gemcitabine plus S-1 (GS) to gemcitabine plus cisplatin (GC) for chemotherapy-naïve advanced biliary tract cancer., Material and Methods: In total, 354 (289 with measurable target lesions) patients enrolled in JCOG1113 were divided into ETS-unachieved and ETS-achieved groups (≥20% tumor reduction at week 6) and DpR-low and DpR-high groups (≥40% maximum shrinkage) until 12 weeks after enrollment. The impact of ETS and DpR on survival outcome was evaluated using the multivariable Cox proportional hazard model., Results: The proportions of patients in the ETS-achieved and DpR-high groups were similar between the 2 treatment arms. The hazard ratios (HRs) of progression-free survival (PFS) and overall survival (OS) for the ETS-achieved group were 0.70 (95% confidence interval (CI), 0.52-0.93) and 0.60 (95%CI, 0.44-0.81), respectively. The HRs of PFS and OS for the DpR-high group were 0.67 (95%CI, 0.48-0.94) and 0.64 (95%CI, 0.46-0.90), respectively. In the subpopulation treatment effect pattern plot analysis, most patients in the ETS-achieved group in the GC arm did not experience disease progression after 12 weeks from the landmark., Conclusion: As on-treatment markers, ETS and DpR were effective tools. ETS was clinically useful, because it can be used to evaluate the outcomes of treatment early at a specific time., (© The Author(s) 2023. Published by Oxford University Press.)
