ABSTRACT
BACKGROUND: Chemoradiotherapy (CRT) with high-dose cisplatin (CDDP) is the standard treatment for locally advanced head and neck squamous cell carcinoma (HNSCC). Although dosing is based on body surface area (BSA), some patients experience CDDP-related adverse events (AEs). We aimed to evaluate the impact of relative CDDP dose to skeletal muscle mass (SMM) on chemotherapy-associated AEs in patients with HNSCC undergoing CRT with high-dose CDDP. MATERIALS AND METHODS: We retrospectively analyzed data of patients who underwent CRT with high-dose CDDP (80-100 mg/m2, triweekly) between 2010 and 2023. SMM was measured as the cross-sectional muscle area at the third cervical vertebra (C3-SMM) using computed tomography; the skeletal muscle index (SMI) was defined as SMM normalized by squared height. The CDDP index was defined as the prescribed CDDP dose divided by SMI. CDDP-related AEs were assessed during the first cycle using Common Terminology Criteria for Adverse Events v5.0. RESULTS: Overall, 306 patients were identified. The CDDP index cutoff value best associated with gradeâ ≥â 3 AEs was 10.312. Gradeâ ≥â 3 hematological toxicities exhibited stronger association with high CDDP index value than with low CDDP index value (26.9% vs 16.3%, Pâ =â .033). Multivariate analysis revealed that high CDDP index value and creatinine clearanceâ <â 70 mL/minute were predictive factors for gradeâ ≥â 3 AEs (odds ratio [OR] 2.55, Pâ =â .008; OR 3.68, Pâ =â .002, respectively). CONCLUSION: The CDDP index based on C3-SMM was an independent predictive factor for gradeâ ≥â 3 CDDP-related AEs. C3-SMM is potentially more useful than BSA for determining the optimal CDDP dose in patients with HNSCC.
ABSTRACT
BACKGROUND: In older patients, esophageal squamous cell carcinoma (ESCC) is difficult to treat using standard therapies, including surgery and cisplatin-based chemoradiotherapy. Paclitaxel (PTX) has radiosensitizing activity. We conducted a phase I trial of PTX combined with radiotherapy to establish a standard therapy for locally advanced ESCC in older patients. METHODS: Enrollment was conducted at six centers in Japan from April 2016 to September 2019. The participants were aged ≥ 70 years, had locally advanced ESCC, and were intolerant to surgery or unwilling. A fixed 60-Gy radiation dose was administered in 30 fractions. PTX dosing levels started at 30 mg/m2 weekly for 6 weeks. Depending on the number of DLTs, the dose was set to be increased by 10 mg/m2 or switched to biweekly. A geriatric assessment was performed before treatment using the Geriatric-8 screening tool. The primary endpoint was dose-limiting toxicity (DLT). RESULTS: We enrolled 24 patients (6 per group); DLT was observed in one (grade 4 hypokalemia), one (grade 3 aspiration), two (grade 3 radiodermatitis, grade 3 esophageal hemorrhage), and two (grade 3 anorexia, grade 5 pneumonitis) patients in the weekly PTX 30, 40, 50, and 60 mg/m2 groups, respectively. All adverse events, except death in the 60 mg/m2 group, showed reversible improvement, and the safety profile was considered acceptable. The 2-year survival and complete response rates were 40.0% and 54.2%, respectively. There was a significant difference in survival between favorable and unfavorable Geriatric-8 scores. CONCLUSIONS: The recommended PTX dose with concomitant radiation was determined to be 50 mg/m2 weekly. Phase II trials at this dose are underway.

Oesophageal squamous cell carcinoma is a common malignancy worldwide. Definitive chemoradiotherapy is the standard treatment for patients with resectable stage oesophageal squamous cell carcinoma who cannot undergo surgery, as well as those with locally advanced unresectable oesophageal squamous cell carcinoma. However, it has several disadvantages such as poor survival, radiation-related toxicities and severe and lethal complications related to salvage treatment for residual or recurrent disease. Numerous clinical trials on chemoradiotherapy have been conducted to confirm the optimal combination of irradiation and chemotherapy. For advanced disease, multimodal treatment strategies including salvage surgery are essential. Palliative chemoradiotherapy is also crucial for dysphagia in locally advanced oesophageal squamous cell carcinoma with or without metastatic lesions. Recently, the synergistic mechanism of radiotherapy combined with immunotherapy has been reported. Early phase clinical trials suggest that a combination of immunotherapy and chemoradiotherapy can improve clinical outcomes with manageable side effects, but further investigations are needed. Here, we reviewed the existing clinical data and current development of chemoradiotherapy combined with immunotherapy in patients with oesophageal squamous cell carcinoma.

Treatment strategies for oesophagogastric junction adenocarcinoma have not been standardized despite its poor prognosis due to differences in the incidence rates between Western countries and Asia. This randomized Phase II/III trial was initiated in June 2023 to determine which neoadjuvant chemotherapy regimen, docetaxel, oxaliplatin and S-1 or fluorouracil, oxaliplatin and docetaxel, is a more promising treatment in Phase II and confirm the superiority of neoadjuvant chemotherapy with docetaxel, oxaliplatin and S-1 or fluorouracil, oxaliplatin and docetaxel followed by surgery and postoperative chemotherapy over upfront surgery and postoperative chemotherapy in terms of overall survival in patients with Clinical Stage III or IVA oesophagogastric junction adenocarcinoma in Phase III. A total of 460 patients, including 150 patients in Phase II and 310 patients in Phase III, are planned to be enrolled from 85 hospitals in Japan over 5 years. This trial has been registered in the Japan Registry of Clinical Trials as jRCTs031230182 (https://jrct.niph.go.jp/latest-detail/jRCTs031230182).

BACKGROUND: Cancer cachexia is characterized by the loss of body weight (BW) and anorexia. Anamorelin (ANAM) is a selective ghrelin receptor agonist with appetite-enhancing anabolic action. The ONO-7643-05 trial demonstrated that ANAM increased lean body mass and improved anorexia in a Japanese population. However, the clinical outcomes of patients on ANAM have not yet been reported. PATIENTS AND METHODS: We investigated the clinical outcomes of patients with unresectable, advanced, or recurrent gastrointestinal cancer (colorectal, gastric, or pancreatic cancer) who were treated with ANAM between April 2017 and August 2022. Cachexia was defined as the presence of anorexia and a loss of ≥ 5% of BW within 6 months. To evaluate the response to ANAM, the patients who had discontinued ANAM within 3 weeks were excluded. Response to ANAM was defined as maintenance of or increase in BW and improved appetite from baseline at every 3-week evaluation. We also collected data on the reasons for the discontinuation of ANAM and the correlation between clinical factors and ANAM response. Safety analysis of ANAM was performed for all patients who received ANAM. RESULTS: Seventy-four patients were included in this study (49 males and 25 females), with a median age of 67.1 years (range, 36-83). The primary tumors were colorectal cancer in 27 (36.5%), gastric cancer in 20 (27.0%), and pancreatic cancer in 27 (36.5%). The Eastern Cooperative Oncology Group performance status was 0 in 10 (13.5%), 1 in 44 (59.5%), and ≥ 2 in 20 (27.0%). The number of previous chemotherapy regimens was 0 in 20 (27.0%), 1 in 22 (29.7%), and ≥ 2 in 32 (43.2%). ANAM was discontinued within 3 weeks in 28 patients for the following reasons: low-grade (grade 1 or 2) adverse events in 15 patients, ileus in three, grade 3 fatigue in one, progressive disease in one, censored follow-up in six, and unknown reasons in three. The proportion of ANAM responders was 63.6% (95% confidence interval, 47.8-77.6%). Among baseline characteristics, age ≥ 75 attenuated the ANAM response (p = 0.03). ANAM responders showed better disease control with chemotherapy than non-responders (75.0% vs. 37.5%, p = 0.02). CONCLUSIONS: ANAM may improve the outcomes of patients with gastrointestinal cancer cachexia in clinical practice.

PURPOSE: Medial open-wedge high tibial osteotomy (OWHTO) is related to cartilage improvement in the medial compartment. This study aimed to evaluate factors associated with cartilage improvement and patient-reported outcomes (PRO) after OWHTO. It was hypothesised that cartilage improvement is associated with favourable PRO. METHODS: This retrospective study included 94 patients who underwent OWHTO. The mean follow-up period was 5 years. The weight-bearing line ratio (WBLR) was defined as the ratio of the distance from the medial tibial edge to the tibial insertion of the weight-bearing line and the tibial width. The International Cartilage Research Society grade evaluated the medial femoral condyle (MFC) and medial tibial plateau (MTP) at initial and second-look arthroscopy, and cartilage improvement after OWHTO was assessed. Postoperative knee injury and osteoarthritis outcome scores (KOOS) were compared between the groups with improved and non-improved cartilage. Additionally, factors related to cartilage improvement and postoperative KOOS scores were analysed. RESULTS: Regarding the MFC, KOOS pain, symptoms, activities of daily living (ADL) and quality of life (QOL) were significantly higher in the cartilage-improved group than in the non-improved group (p = 0.012, 0.003, 0.001, 0.006), and cartilage improvement was significantly related to KOOS pain, ADL and QOL (p = 0.021, 0.039, 0.013). In addition, the postoperative WBLR was associated with cartilage improvement, with a cutoff value of 54.0% (p = 0.046). Regarding the MTP, KOOS ADL and QOL (p = 0.026, 0.022) were significantly higher in the cartilage-improved group than in the nonimproved group. Body mass index (BMI) was significantly related to the postoperative QOL (p = 0.018) and associated with cartilage improvement, with a cutoff value of 25.9 kg/m2 (p = 0.002). CONCLUSION: A postoperative WBLR greater than 54.0% and a preoperative BMI below 25.9 kg/m2 were associated with cartilage improvement, positively impacting PRO after OWHTO. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

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.

BACKGROUND: In this phase Ib study MODURATE, we optimized the dosing schedule and tested the efficacy and safety of trifluridine/tipiracil, irinotecan, and bevacizumab in patients with metastatic colorectal cancer with fluoropyrimidine and oxaliplatin treatment failure. METHODS: We included a dose escalation (3 + 3 design) and an expansion cohort. Patients were administered trifluridine/tipiracil (25-35 mg/m2 twice daily, days 1-5), irinotecan (150-180 mg/m2, day 1), and bevacizumab (5 mg/kg, day 1) every 2 weeks. The recommended phase II dose (RP2D) in the dose escalation cohort was administered to at least 15 patients in both cohorts combined. RESULTS: Twenty-eight patients were enrolled. Five dose-limiting toxicities were observed. RP2D was defined as trifluridine/tipiracil 35 mg/m2, irinotecan 150 mg/m2, and bevacizumab 5 mg/kg. Of 16 patients who received RP2D, 86% (14/16) experienced grade ≥3 neutropenia without febrile neutropenia. Dose reduction, delay, and discontinuation occurred in 94%, 94%, and 6% of patients, respectively. Three patients (19%) showed partial response and 5 had stable disease for >4 months, with a median progression-free and overall survival of 7.1 and 21.7 months, respectively. CONCLUSION: Biweekly trifluridine/tipiracil, irinotecan, and bevacizumab administration may have moderate antitumor activity with high risk of severe myelotoxicity in previously treated patients with metastatic colorectal cancer [UMIN Clinical Trials Registry (UMIN000019828) and Japan Registry of Clinical Trials (jRCTs041180028)].

Familial malignant melanoma (FMM) is a hereditary tumor that is quite rare in Japan; to date, the germline CDK4 variant has scarcely been reported around the world. Thus, we report on a woman with FMM who developed salivary gland cancer, for which a germline pathogenic variant of CDK4 was incidentally identified through comprehensive genomic profiling. She had a history of multiple atypical nevi and a facial melanoma since her 30 s and multiple family histories of melanoma; however, none of her relatives were aware of its heredity. Genetic counseling and skin surveillance were performed. Precision medicine for cancer can discover this rare genetic syndrome and provides us with the opportunity to manage the health of patients and their relatives.

BACKGROUND: Nanoliposomal irinotecan plus fluorouracil/leucovorin (5-FU/LV) is a standard second-line therapy for patients with pancreatic cancer. Identification of biomarkers is important to determine appropriate treatment strategies. We investigated the clinical practice outcomes and biomarkers associated with the nanoliposomal irinotecan plus 5-FU/LV regimen. METHODS: We retrospectively reviewed the data of patients treated with nanoliposomal irinotecan plus 5-FU/LV as a second or subsequent treatment after gemcitabine-based therapy between June 2020 and March 2021 at Shizuoka Cancer Center. RESULTS: We analyzed 55 consecutive patients who met the selection criteria. At a median of 9.4 months, median progression-free survival (PFS) and median overall survival (OS) were 2.3 and 6.6 months, respectively. Multivariate analysis showed that Glasgow prognostic score (GPS) was significantly associated with PFS (hazard ratio [HR] 2.16; 95% confidence interval [CI] 1.09-4.30; P = 0.028) and OS (0 vs. 1 or 2: HR 2.46; 95% CI 1.15-5.25; P = 0.029). The OS was significantly longer in patients with CA19-9 response than in those without CA19-9 response (12.6 vs. 5.6 months; HR 0.24; 95% CI 0.08-0.75; P = 0.014). CONCLUSIONS: Nanoliposomal irinotecan was efficacious and tolerable in clinical practice. GPS and CA19-9 response were good candidates as predictive biomarkers, whereas GPS was a good candidate prognostic biomarker for the nanoliposomal irinotecan plus 5-FU/LV regimen.

AIMS: Patients who undergo permanent pacemaker (PPM) implantation after transcatheter aortic valve replacement (TAVR) have a worse outcome. The aim of this study was to identify risk factors of worse outcomes in patients with post-TAVR PPM implantation. METHODS AND RESULTS: This is a single-centre, retrospective study of consecutive patients who underwent post-TAVR PPM implantation from 11 March 2011 to 9 November 2019. Clinical outcomes were evaluated by landmark analysis with cut-off at 1 year after the PPM implantation. Of the 1389 patients underwent TAVR during the study duration and a total of 110 patients were included in the final analysis. Right ventricular pacing burden (RVPB) ≥ 30% at 1 year was associated with a higher likelihood of heart failure (HF) readmission [adjusted hazard ratio (aHR): 6.333; 95% confidence interval [CI]: 1.417-28.311; P = 0.016] and composite endpoint of overall death and/or HF (aHR: 2.453; 95% CI: 1.040-5.786; P = 0.040). The RVPB ≥30% at 1 year was associated with higher atrial fibrillation burden (24.1 ± 40.6% vs. 1.2 ± 5.3%; P = 0.013) and a decrease in left ventricular ejection fraction (-5.0 ± 9.8% vs. + 1.1 ± 7.9%; P = 0.005). The predicting factors of the RVPB ≥30% at 1 year were the presence of RVPB ≥40% at 1 month and the valve implantation depth measured from non-coronary cusp ≥4.0 mm (aHR: 57.808; 95% CI: 12.489-267.584; P < 0.001 and aHR: 6.817; 95% CI: 1.829-25.402; P = 0.004). CONCLUSIONS: The RVPB ≥30% at 1 year was associated with worse outcomes. Clinical benefit of minimal RV pacing algorithms and biventricular pacing needs to be investigated.

OBJECTIVE: To review evidence of existing and new pharmacological therapies for lowering lipoprotein(a) (Lp[a]) concentrations and their impact on clinically relevant outcomes. METHODS: We searched for literature pertaining to Lp(a) and pharmacological treatments in PubMed. We reviewed articles published between 1963 and 2020. RESULTS: We found that statins significantly increased Lp(a) concentrations. Therapies that demonstrated varying degrees of Lp(a) reduction included ezetimibe, niacin, proprotein convertase subtilisin/kexin type 9 inhibitors, lipoprotein apheresis, fibrates, aspirin, hormone replacement therapy, antisense oligonucleotide therapy, and small interfering RNA therapy. There was limited data from large observational studies and post hoc analyses showing the potential benefits of these therapies in improving cardiovascular outcomes. CONCLUSION: There are multiple lipid-lowering agents currently being used to treat hyperlipidemia that also have a Lp(a)-lowering effect. Two RNA therapies specifically targeted to lower Lp(a) are being investigated in phase 3 clinical trials and, thus far, have shown promising results. However, evidence is lacking to determine the clinical relevance of reducing Lp(a). At present, there is a need for large-scale, randomized, controlled trials to evaluate cardiovascular outcomes associated with lowering Lp(a).

BACKGROUND: We herein investigated the association between early tumor shrinkage (ETS) and depth of response (DpR) and clinical outcomes in patients with metastatic esophageal cancer treated with 2-weekly docetaxel combined with cisplatin plus fluorouracil (bDCF) using data from the JCOG0807, a phase I/II trial of bDCF as first-line chemotherapy for metastatic esophageal cancer. METHODS: ETS was defined as a percent decrease in the sum of the target lesions' longest diameter after 8 weeks, whereas DpR was defined as a percentage of the maximal tumor shrinkage during the treatment course. Multivariable analyses were conducted to identify significant prognostic variables in progression-free survival (PFS) and overall survival (OS): one for ETS and covariates, and another for DpR and covariates. RESULTS: Among 53 patients, 35 patients with ETS ≥ 20% (66.0%) had longer PFS (7.5 vs. 3.4 months, hazard ratio [HR]: 0.26, 95% confidence interval [95% CI] 0.14-0.49), OS (13.8 vs. 6.1 months, HR 0.20, 95% CI 0.11-0.39), and PPS (6.4 vs. 2.8 months, HR 0.38, 95% CI 0.20-0.72) than those with ETS < 20%. In addition, 37 patients with DpR ≥ 30% (69.8%) had longer PFS (7.5 vs. 2.9 months, HR 0.17, 95% CI 0.08-0.34), OS (13.8 vs. 6.0 months, HR 0.14, 95% CI 0.07-0.27), and PPS (6.8 vs. 2.8 months, HR 0.30, 95% CI 0.15-0.58) than those with DpR < 30%. Multivariable analyses revealed that each ETS and DpR was an independent factor of longer PFS and OS. CONCLUSIONS: ETS and DpR might be associated with clinical outcomes in patients with metastatic esophageal cancer treated with bDCF.

BACKGROUND: The registration committee for esophageal cancer in the Japan Esophageal Society (JES) has collected the patients' characteristics, treatment, and outcomes of patients who underwent any treatment during 2015 in Japan. METHODS: We analyzed patients' data who had visited the participating hospitals in 2015. We collected the data using the National Clinical Database with a web-based data collection system. We used the Japanese Classification of Esophageal Cancer 10th edition by JES and the TNM classification by the Union of International Cancer Control (UICC) for cancer staging. RESULTS: A total of 9368 cases were registered from 355 institutions in Japan. Squamous cell carcinoma and adenocarcinoma accounted for 86.7% and 7.4%, respectively. The 5-year survival rates of patients treated by endoscopic resection, concurrent chemoradiotherapy, radiotherapy alone, and esophagectomy were 87.2%, 33.5%, 24.2%, and 59.9%, respectively. Esophagectomy was performed in 5172 cases. Minimally invasive approaches were selected for 60.6%, and 54.4% underwent thoracoscopic esophagectomy. The operative mortality (within 30 days after surgery) was 0.79% and the hospital mortality was 2.3%. The survival curves showed an excellent discriminatory ability both in the clinical and pathologic stages by the JES system. The survival of pStage IV was better than IIIC in the UICC system because pStage IV included the patients with supraclavicular lymph node metastasis (M1 LYM). CONCLUSION: We hope this report improves all aspects of diagnosing and treating esophageal cancer in Japan.

This systematic review was performed to investigate the superiority of proton beam therapy (PBT) to photon-based radiotherapy (RT) in treating esophageal cancer patients, especially those with poor cardiopulmonary function. The MEDLINE (PubMed) and ICHUSHI (Japana Centra Revuo Medicina) databases were searched from January 2000 to August 2020 for studies evaluating one end point at least as follows; overall survival, progression-free survival, grade ≥ 3 cardiopulmonary toxicities, dose-volume histograms, or lymphopenia or absolute lymphocyte counts (ALCs) in esophageal cancer patients treated with PBT or photon-based RT. Of 286 selected studies, 23 including 1 randomized control study, 2 propensity matched analyses, and 20 cohort studies were eligible for qualitative review. Overall survival and progression-free survival were better after PBT than after photon-based RT, but the difference was significant in only one of seven studies. The rate of grade 3 cardiopulmonary toxicities was lower after PBT (0-13%) than after photon-based RT (7.1-30.3%). Dose-volume histograms revealed better results for PBT than photon-based RT. Three of four reports evaluating the ALC demonstrated a significantly higher ALC after PBT than after photon-based RT. Our review found that PBT resulted in a favorable trend in the survival rate and had an excellent dose distribution, contributing to reduced cardiopulmonary toxicities and a maintained number of lymphocytes. These results warrant novel prospective trials to validate the clinical evidence.

BACKGROUND: Bone marrow lesion (BML) is an important magnetic resonance finding (MRI) finding that predicts knee osteoarthritis. The purpose of this study was to investigate the influence of proximal tibial morphology on BML, including the spreading root sign (SRS), in women without radiographic knee osteoarthritis (OA). It was hypothesized that varus alignment and a greater posterior tibial slopes (PTS) are associated with BML. MATERIALS AND METHODS: A total of 359 female volunteers without knee OA who were participants in the Iwaki Health Promotion Project in 2017 or 2019 were enrolled. Participants were divided into the non-OA and early knee OA (EKOA) groups based on the Luyten's classification criteria. The presence of pathological cartilage lesions, BMLs, attritions, meniscal lesions and effusions was scored on T2-weighted fat-suppressed magnetic resonance imaging (MRI) according to the Whole-Organ MRI Scoring system. The medial proximal tibial angle (MPTA) and medial and lateral PTS (MPTS and LPTS, respectively) were measured. Regression and receiver operating characteristic (ROC) analyses were performed to reveal the relationship between BMLs and proximal tibial morphological parameters. RESULTS: Of the 359 participants, 54 (15%) were classified as having EKOA. The prevalence of cartilage lesions, BMLs, attritions, meniscal lesions and effusions was higher in the EKOA group than in the non-OA group. The two groups had no significant difference in the proximal tibial parameters. Regression analysis revealed that age and a smaller MPTA were associated with BML in both groups. Attrition (p = 0.029) and the MPTS (p = 0.025) were positively associated with BML in the EKOA group. CONCLUSION: The prevalence of BMLs was higher in women with EKOA and correlated with the varus and greater posterior slopes in those without radiographic knee OA. LEVEL OF EVIDENCE: Level III, retrospective case-control study.

The KEYNOTE-659 study evaluated the efficacy and safety of first-line pembrolizumab plus S-1 and oxaliplatin (SOX) (cohort 1) or S-1 and cisplatin (SP) (cohort 2) for advanced gastric/gastroesophageal junction (G/GEJ) cancer in Japan. Herein, we update the results of cohort 1 and describe the results of cohort 2. This open-label phase IIb study enrolled patients with advanced programmed death-ligand 1 (PD-L1)-positive (combined positive score ≥ 1) human epidermal growth factor receptor 2 (HER2)-negative G/GEJ adenocarcinoma. The primary end-point was the objective response rate (ORR). Other end-points were duration of response (DOR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety. One hundred patients were enrolled. In cohorts 1 and 2, median follow-up time was 16.9 and 17.1 months; ORR (central review), 72.2% and 80.4%; DOR, 10.6 and 9.5 months; DCR (central review), 96.3% and 97.8%; median PFS (central review), 9.4 and 8.3 months; and median OS, 16.9 and 17.1 months, respectively. Treatment-related adverse events (TRAEs) occurred in all patients, including peripheral sensory neuropathy (94.4%, cohort 1), decreased neutrophil count (82.6%, cohort 2), nausea (59.3% and 60.9% in cohorts 1 and 2), and decreased appetite (61.1% and 60.9% in cohorts 1 and 2). Grade 3 or higher TRAEs were reported by 59.3% (cohort 1) and 78.3% (cohort 2), including decreased platelet count (14.8%, cohort 1) and decreased neutrophil count (52.2%, cohort 2). Pembrolizumab in combination with SOX or SP showed favorable efficacy and safety in patients with PD-L1-positive, HER2-negative G/GEJ adenocarcinoma.

PURPOSE: This study aimed to evaluate the effectiveness and safety of gemcitabine (GEM) plus nab-paclitaxel (GnP) in patients aged ≥ 75 years with advanced pancreatic cancer and compare it with monotherapy (GEM or S-1). METHODS: We retrospectively reviewed the data of consecutive patients with advanced pancreatic cancer aged ≥ 75 years who received either GnP or monotherapy (GEM or S-1) between January 2014 and May 2020. The primary efficacy outcome was overall survival (OS). RESULTS: A total of 96 patients were included in this study; 51 were treated with GnP and 45 with monotherapy (31 with GEM and 14 with S-1). The median OS and progression-free survival were 10.8 and 6.7 months in the GnP group and 10.7 and 4.3 months in the monotherapy group, respectively. The treatment effect on OS was consistently favorable in the GnP group across most subgroups, particularly in patients with locally advanced cancer, modified Glasgow prognostic score of 0 or 1, and neutrophil/lymphocyte ratio < 3.1. The disease control rates were 76% and 48% in the GnP and monotherapy groups, respectively, and grade 3 or 4 neutropenia occurred in 23 (45%) and 11 (24%) patients of the GnP and monotherapy groups, respectively. CONCLUSIONS: This study demonstrated that GnP was not superior to monotherapy with regard to OS. However, multivariate analysis showed that GnP treatment positively affected the OS and could be considered as a treatment option, even for elderly patients.

PURPOSE: This study aimed to evaluate the relationship between status epilepticus (SE) and cardiorespiratory comorbidity in patients with epilepsy. METHODS: We conducted a population-based study using cloud-based aggregated electronic medical records from >53 million patients in the US (Explorys, IBM Watson; January 1999 to November 2020). During the study period, we identified patients with epilepsy with SE. Patients with a history of cardiac arrest, anoxic encephalopathy, and/or cerebrovascular disease were excluded. We reported the prevalences and prevalence ratios of cardiorespiratory and medical comorbidities using age- and sex-adjusted standardization. RESULTS: We identified 494,790 patients with epilepsy and 19,190 had SE. Cardiovascular and respiratory diseases were statistically significantly more prevalent in patients with epilepsy with SE than in those without SE (adjusted prevalence ratio (APR) 1.13, prevalence 68.7% [95% confidence interval (CI): 67.6-69.9] vs 60.9% [95% CI: 60.7-61.1]) and (APR 1.25, 73.1% [95% CI: 71.8-74.3] vs 58.4% [95% CI: 58.1-58.6]), respectively. Aspiration pneumonia (APR 3.12, 0.47% [95% CI: 0.37-0.57] vs 0.15% [95% CI: 0.14-0.16]) and acute respiratory distress syndrome (APR 2.40, 0.47% [95% CI: 0.37-0.57] vs 0.20% [95% CI: 0.18-0.21]) were more prevalent in patients with epilepsy with SE. Common cardiovascular risk factors such as diabetes mellitus (APR 1.13, 17.1% [95% CI: 16.5-17.6] vs 15.1% [95% CI: 1.50-15.2]) and hypertension (APR 1.28, 10.6% [95% CI: 10.2-11.0] vs 8.31% [95% CI: 8.23-8.39]) were also more common in patients with epilepsy with SE. CONCLUSION: In this population-based study, patients with epilepsy with SE had a statistically significantly higher prevalence of cardiorespiratory comorbidities than in those without SE.

BACKGROUND: The standard treatment for unresectable advanced/recurrent esophageal cancer in Japan is 5-fluorouracil plus platinum-containing drugs as first-line chemotherapy and taxanes as second-line chemotherapy. However, the standard regimen after patients become refractory to these treatments remains to be established. Therefore, we investigated the efficacy of trifluridine/tipiracil (FTD/TPI) in patients with esophageal cancer who are refractory or intolerant to 5-fluorouracil, platinum-containing drugs, and taxanes. METHODS: This single-arm phase II trial was conducted in seven hospitals in Japan. Eligible patients were those with unresectable advanced/recurrent esophageal cancer that was refractory or intolerant to 5-fluorouracil, platinum-containing drugs, and taxanes. The primary endpoint was the 3-month progression-free survival rate, and the secondary endpoints were the 6-month progression-free survival rate, progression-free survival, overall survival, response rate, disease control rate, and toxicity. RESULTS: Forty-two patients were enrolled between October 2015 and June 2016. All tumors were squamous cell carcinomas. The progression-free survival rates at 3 and 6 months were 15.4% (90% confidence interval 7.4-26.0%) and 7.7% (90% confidence interval 2.6-16.6%), respectively. The median progression-free survival and median overall survival were 1.3 (95% confidence interval 1.0-1.8) months and 4.5 (95% confidence interval 3.6-5.7) months, respectively. The response rate was 0%, and the disease control rate was 23.8% (95% confidence interval 13.5-38.5%). The major grade 3/4 toxicities were neutropenia (47.6%), leukocytopenia (35.7%), and anemia (21.4%). No treatment-related deaths occurred. Exploratory subgroup analyses showed better progression-free survival in the subgroup without distant metastasis at diagnosis. CONCLUSIONS: Trifluridine/tipiracil monotherapy is feasible and shows modest activity in patients with refractory esophageal squamous cell carcinoma.
