    Abstract Pancreatic cancer (PC) remains an incurable disease with few treatment options Recently, promising targets have been identified and novel therapeutic drugs are currently under development in KRAS wild-type PC. It has been reported that KRAS wild-type PC has the genomic alterations such as oncogenic derivers and kinase fusions. NRG1 fusion, which encodes the neuregulin 1 and is the main ligands for ERRB3, has been identified in approximately half of younger patients with PC with KRAS wild-type tumors by RNA sequencing. There are several promising targeted therapies for NRG1 fusion-positive tumors, such as EGFR-tyrosine kinase inhibitor, HER3, HER2 antibodies. BRAF, NTRK, and ALK fusion are also potentially actionable alterations in KRAS wild-type PC and novel therapies targeting certain aberrations have shown activity in clinical trials.

    Abstract Deficient mismatch repair (dMMR) results in microsatellite instability (MSI), a pronounced mutator phenotype. High-frequency MSI (MSI-H)/dMMR is gaining increasing interest as a biomarker for advanced cancer patients to determine their eligibility for immune checkpoint inhibitors (ICIs). Various methods based on next-generation sequencing (NGS) have been developed to assess the MSI status. Comprehensive genomic profiling (CGP) testing can precisely ascertain the MSI status as well as genomic alterations in a single NGS test. The MSI status can be also ascertained through the liquid biopsy-based CGP assays. MSI-H has thus been identified in various classes of tumors, resulting in a greater adoption of immunotherapy, which is hypothesized to be effective against malignancies that possess a substantial number of mutations and/or neoantigens. NGS-based studies have also characterized MSI-driven carcinogenesis, including significant rates of fusion kinases in colorectal cancers (CRCs) with MSI-H that are targets for therapeutic kinase inhibitors, particularly in MLH1-methylated CRCs with wild-type KRAS/BRAF. NTRK fusion is linked to the colorectal serrated neoplasia pathway. Recent advances in investigations of MSI-H malignancies have resulted in the development of novel diagnostic or therapeutic techniques, such as a synthetic lethal therapy that targets the Werner gene. DNA sensing in cancer cells is required for antitumor immunity induced by dMMR, opening up novel avenues and biomarkers for immunotherapy. Therefore, clinical relevance exists for analyses of MSI and MSI-H-associated genomic alterations in malignancy. In this article, we provide an update on MSI-driven carcinogenesis, with an emphasis on unique landscapes of diagnostic and immunotherapeutic strategies.

    Abstract Background: Oxaliplatin-containing adjuvant regimens (folinic acid, fluorouracil, and oxaliplatin/capecitabine and oxaliplatin [FOLFOX/CAPOX]) are used after curative resection of colorectal cancer (CRC). However, real-world evidence regarding treatment sequences and outcomes in patients with early recurrence CRC after adjuvant chemotherapy is limited.
    Objective: We aimed to describe the patient characteristics, treatment sequence, and overall duration of second-line (2L) therapy in patients with early recurrence CRC who received adjuvant chemotherapy (FOLFOX/CAPOX) followed by folinic acid, fluorouracil, and irinotecan (FOLFIRI) + anti-angiogenesis drugs (AA) or FOLFIRI + anti-epidermal growth factor receptor (EGFR) antibodies.
    Methods: This retrospective study analyzed Japanese administrative data from November 2014 to March 2023 of adult patients who underwent CRC resection surgery, started FOLFOX/CAPOX ≤3 months (mo) after surgery, and had early CRC recurrence. Early recurrence was defined as initiation of FOLFIRI+AA or FOLFIRI+anti-EGFR antibodies as 2L therapy, ≤12 mo of discontinuing adjuvant chemotherapy. Patient characteristics, treatment sequence, median time to treatment discontinuation (mTTD), i.e., duration between the start and end dates of 2L therapy (Kaplan-Meier method), and factors associated with 2L time to treatment discontinuation constituted the study outcomes (Cox regression model). Subgroup analyses were performed for timing of early CRC recurrence (≤6 mo and 6-12 mo) and tumor sidedness.
    Results: Among the 832 selected patients (median age [minimum-maximum] 67 (24-86) years, 56.4% male), CAPOX (71.3%) was more commonly used than FOLFOX (28.7%) as adjuvant therapy. FOLFIRI+AA (72.5%) was used more commonly than FOLFIRI+anti-EGFR antibodies (27.5%) in 2L. AA and anti-EGFR antibodies groups had similar mTTD: 6.2 mo (95% confidence interval 5.8, 6.9) and 6.1 mo (95% confidence interval 5.2, 7.4). Age ≥70 years showed significant association with shorter 2L treatment duration (hazard ratio 1.2, 95% confidence interval 1.0, 1.4; p = 0.03). The AA cohort's mTTD was numerically shorter in the ≤6 mo recurrence subgroup compared with the 6-12 mo recurrence subgroup (6.1 mo vs 8.1 mo); the anti-EGFR antibodies cohort had similar mTTD (5.8 mo vs 6.2 mo). The AA and anti-EGFR antibodies cohorts also had similar mTTD in the left-sided CRC subgroup (6.5 mo vs 6.2 mo), but not in the right-sided subgroup (5.6 mo vs 3.9 mo).
    Conclusions: This is the first administrative data-based real-world evidence on treatment sequence and outcomes for patients with early recurrence CRC treated with FOLFIRI+AAs or FOLFIRI+ anti-EGFR antibodies after adjuvant FOLFOX/CAPOX therapy in Japan. Both regimens had similar TTD, but relapse timing and tumor sidedness may influence their efficacy.

    Abstract Angiogenesis is a hallmark of cancer development. This study sought to determine the recommended dose of aflibercept, a recombinant fusion protein targeting VEGF-A, VEGF-B and placental growth factor (PlGF), combined with docetaxel in Japanese patients with advanced solid malignancies. This phase I study was planned to include 12 patients following a 3 + 3 algorithm to determine the maximum tolerated dose of aflibercept combined with docetaxel in patients with metastatic or unresectable solid tumors (trial registration: NCT00545246). Docetaxel (75 mg/m<sup>2</sup> every 3 weeks or 60 mg/m<sup>2</sup> after protocol amendment) was combined with escalating doses of aflibercept (2, 4 and 6 mg/kg every 4 weeks). Free and VEGF-bound aflibercept were measured to assess free aflibercept in excess of the VEGF-bound form. At the starting dose of the combination, 3 of 6 patients treated experienced febrile neutropenia. After reducing the docetaxel dose to 60 mg/m<sup>2</sup> in step 2 and permitting therapeutic granulocyte colony-stimulating factor (G-CSF) use, 2 of 3 patients in both cohorts experienced febrile neutropenia. Five patients (42%) had a partial response and 4 patients had stable disease (33%). Free aflibercept in excess of the VEGF-bound form was not maintained at this dose level. The dose limiting toxicity (DLT) of aflibercept combined with docetaxel was febrile neutropenia, which occurred in 2 of 3 Japanese patients at the lowest aflibercept dose level (2 mg/kg) combined with docetaxel (60 mg/m<sup>2</sup>) and therapeutic G-CSF use. A recommended dose for further studies was not determined because of the DLT at the starting dose.

    Abstract Background: Geriatric 8 (G8) and instrumental activities of daily living (IADL) are recommended to predict overall survival (OS) or risk of serious adverse events (SAEs) in older cancer patients. However, the clinical utility is relatively unknown in older patients suffering malnutrition with gastrointestinal (GI) cancer, including gastric cancer (GC) and pancreatic cancer (PC).
    Materials and methods: We retrospectively included patients aged ≥65 years with GC, PC, and colorectal cancer (CRC) who received a G8 questionnaire at first visit from April 2018 to March 2020. The associations between G8/IADL and safety or OS were assessed in patients with advanced/unresectable tumors.
    Results: Of 207 patients (median age: 75 years), the median G8 score was 10.5 and normal G8 score rate was 6.8%. Both the median G8 score and normal G8 (>14) score rate numerically increased in the order of GC < PC < CRC. There was no clear association between the G8 standard cutoff value of 14 and SAEs or OS. However, OS was significantly longer in patients with G8 >11 than in those with G8 ≤11 (19.3 vs. 10.5 months,
    Conclusion: The G8 cutoff value of 14 would not be clinically useful in patients with GI cancer for predicting OS or SAEs; however, the cutoff value of 11 and IADL may be useful to predict OS for older patients with GI cancers including GC and PC.

    Abstract Purpose: A phase III trial comparing S-1 and docetaxel with S-1 alone as postoperative chemotherapy for pathologically Stage III gastric cancer was conducted and clarified the superiority of the doublet in terms of 3-year relapse-free survival as the primary endpoint (67.7% versus 57.4%, hazard ratio [HR] 0.715, 95% confidence interval [CI] 0.587-0.871; p = 0.0008). This final report analyzed 5-year survival outcomes along with the incidence and pattern of late recurrences.
    Patients and methods: Patients with histologically confirmed Stage III gastric cancer who underwent gastrectomy with D2 lymphadenectomy were randomly assigned to receive adjuvant chemotherapy with either S-1 plus docetaxel or S-1 alone. The same 912 patients who were evaluated for 3-year survival outcomes in the previous report were analyzed.
    Results: Five-year overall survival rate of the S-1 plus docetaxel group (67.91%) was significantly superior to that in the S-1 group (60.27%; HR 0.752, 95% CI 0.613-0.922; p = 0.0059). The incidence of late recurrence at > 3 years after randomization was similar in both groups (7.3% versus 7.2%). Peritoneal dissemination was the most common pattern of late recurrence. Addition of docetaxel significantly suppressed relapse through the lymphatic (6.8% [95% CI 4.52-9.17] versus 15% [95% CI 11.76-18.30]; p < 0.0001) and hematogenous (10.2% [95% CI 7.37-12.94] versus 15.7% [95% CI 12.36-19.01]; p < 0.0137) pathways throughout the 5 years of follow-up.
    Conclusion: The survival benefit of postoperative chemotherapy with S-1 and docetaxel in terms of 5-year overall survival rate was confirmed for patients with pathologically Stage III gastric cancer, although late recurrences were not prevented.

    Abstract Background: Esophageal squamous cell carcinoma (ESCC) has a poor prognosis, with limited second-line systemic therapy options, and represents an increasing disease burden in Japan. In the phase 3 RATIONALE-302 study, the anti-programmed cell death protein 1 antibody, tislelizumab, significantly improved overall survival (OS) versus chemotherapy as second-line treatment for advanced/metastatic ESCC. Here, we report the Japanese patient subgroup results.
    Methods: Patients with advanced/metastatic ESCC, with disease progression during/after first-line systemic therapy were randomized 1:1 to open-label tislelizumab 200 mg every 3 weeks or investigator's choice of chemotherapy (paclitaxel/docetaxel). Efficacy and safety were assessed in all randomized Japanese patients.
    Results: The Japanese subgroup comprised 50 patients (n = 25 per arm). Tislelizumab improved OS versus chemotherapy (median: 9.8 vs. 7.6 months; HR 0.59; 95% CI 0.31, 1.12). Among patients with programmed death-ligand 1 score ≥ 10%, median OS was 12.5 months with tislelizumab (n = 10) versus 2.9 months with chemotherapy (n = 6) (HR 0.31; 95% CI 0.09, 1.03). Tislelizumab improved progression-free survival versus chemotherapy (median: 3.6 vs. 1.7 months, respectively; HR 0.50; 95% CI 0.27, 0.95). Objective response rate was greater with tislelizumab (32.0%) versus chemotherapy (20.0%), and responses were more durable (median duration of response: 8.8 vs. 2.6 months, respectively). Fewer patients experienced ≥ grade 3 treatment-related adverse events with tislelizumab (24.0%) versus chemotherapy (47.8%). Tislelizumab demonstrated an improvement in health-related quality of life versus chemotherapy.
    Conclusions: As second-line therapy for advanced/metastatic ESCC, tislelizumab improved OS versus chemotherapy, with a favorable safety profile, in the Japanese patient subgroup, consistent with the overall population.
