Association of Cancer and Its Interaction with Conventional Risk Factors on Cardiovascular Disease Risk.

Introduction We sought to examine the association of cancer history with the incidence of individual cardiovascular disease events and to clarify whether the history of cancer modifies the relationship between conventional cardiovascular risk factors and incident cardiovascular disease. Methods This retrospective cohort study used the JMDC Claims Database, including 3,531,683 individuals. The primary endpoint was the composite cardiovascular disease outcome, which included myocardial infarction, angina pectoris, stroke, heart failure, and atrial fibrillation. Results During a follow-up, 144,162 composite endpoints were recorded. Individuals with a history of cancer had a higher risk of developing composite cardiovascular disease events (HR 1.26, 95% CI 1.22-1.29). The HRs for myocardial infarction, angina pectoris, stroke, heart failure, and atrial fibrillation were 1.11 (95% CI 0.98-1.27), 1.15 (95% CI 1.10-1.20), 1.11 (95% CI 1.05-1.18), 1.39 (95% CI 1.34-1.44), and 1.22 (95% CI 1.13-1.32), respectively. Individuals who required chemotherapy for cancer had a higher risk of developing cardiovascular disease. Although conventional risk factors (e.g., overweight/obesity, hypertension, and diabetes) were associated with incident composite cardiovascular disease even in individuals with a history of cancer, the total population-attributable fractions of conventional risk factors were less in individuals with a history of cancer. Conclusion Individuals with a history of cancer (particularly those requiring chemotherapy) have a higher risk of cardiovascular disease. Traditional risk factors are important in the development of cardiovascular disease in individuals with and without a history of cancer. In individuals with a history of cancer, however, the total population-attributable fractions of conventional risk factors decreased.

Plasma ANGPTL8 Levels and Risk for Secondary Cardiovascular Events in Japanese Patients With Stable Coronary Artery Disease Receiving Statin Therapy.

BACKGROUND: The ability to predict secondary cardiovascular events could improve health of patients undergoing statin treatment. Circulating ANGPTL8 (angiopoietin-like protein 8) levels, which positively correlate with proatherosclerotic lipid profiles, activate the pivotal proatherosclerotic factor ANGPTL3. Here, we assessed potential association between circulating ANGPTL8 levels and risk of secondary cardiovascular events in statin-treated patients. METHODS: We conducted a biomarker study with a case-cohort design, using samples from a 2018 randomized control trial known as randomized evaluation of high-dose (4 mg/day) or low-dose (1 mg/day) lipid-lowering therapy with pitavastatin in coronary artery disease (REAL-CAD [Randomized Evaluation of Aggressive or Moderate Lipid-Lowering Therapy With Pitavastatin in Coronary Artery Disease])." From that study's full analysis set (n=12 413), we selected 2250 patients with stable coronary artery disease (582 with the primary outcome, 1745 randomly chosen, and 77 overlapping subjects). A composite end point including cardiovascular-related death, nonfatal myocardial infarction, nonfatal ischemic stroke, or unstable angina requiring emergent admission was set as a primary end point. Circulating ANGPTL8 levels were measured at baseline and 6 months after randomization. RESULTS: Over a 6-month period, ANGPTL8 level changes significantly decreased in the high-dose pitavastatin group, which showed 19% risk reduction of secondary cardiovascular events compared with the low-dose group in the REAL-CAD [Randomized Evaluation of Aggressive or Moderate Lipid-Lowering Therapy With Pitavastatin in Coronary Artery Disease] study. In the highest quartiles, relative increases in ANGPTL8 levels were significantly associated with increased risk for secondary cardiovascular events, after adjustment for several cardiovascular disease risk factors and pitavastatin treatment (hazard ratio in Q4, 1.67 [95% CI, 1.17-2.39). Subgroup analyses showed relatively strong relationships between relative ANGPTL8 increases and secondary cardiovascular events in the high-dose pitavastatin group (hazard ratio in Q4, 2.07 [95% CI, 1.21-3.55]) and in the low ANGPTL8 group at baseline (166

Long-term care facilities' response to the COVID-19 pandemic: An international, cross-sectional survey.

AIMS: To (i) assess the adherence of long-term care (LTC) facilities to the COVID-19 prevention and control recommendations, (ii) identify predictors of this adherence and (iii) examine the association between the adherence level and the impact of the pandemic on selected unfavourable conditions. DESIGN: Cross-sectional survey. METHODS: Managers (n = 212) and staff (n = 2143) of LTC facilities (n = 223) in 13 countries/regions (Brazil, Egypt, England, Hong Kong, Indonesia, Japan, Norway, Portugal, Saudi Arabia, South Korea, Spain, Thailand and Turkey) evaluated the adherence of LTC facilities to COVID-19 prevention and control recommendations and the impact of the pandemic on unfavourable conditions related to staff, residents and residents' families. The characteristics of participants and LTC facilities were also gathered. Data were collected from April to October 2021. The study was reported following the STROBE guidelines. RESULTS: The adherence was significantly higher among facilities with more pre-pandemic in-service education on infection control and easier access to information early in the pandemic. Residents' feelings of loneliness and feeling down were the most affected conditions by the pandemic. More psychological support to residents was associated with fewer residents' aggressive behaviours, and more psychological support to staff was associated with less work-life imbalance. CONCLUSIONS: Pre-pandemic preparedness significantly shaped LTC facilities' response to the pandemic. Adequate psychological support to residents and staff might help mitigate the negative impacts of infection outbreaks. IMPACT: This is the first study to comprehensively examine the adherence of LTC facilities to COVID-19 prevention and control recommendations. The results demonstrated that the adherence level was significantly related to pre-pandemic preparedness and that adequate psychological support to staff and residents was significantly associated with less negative impacts of the pandemic on LTC facilities' staff and residents. The results would help LTC facilities prepare for and respond to future infection outbreaks. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

Clinical utility of Todai OncoPanel in the setting of approved comprehensive cancer genomic profiling tests in Japan.

Comprehensive cancer genome profiling (CGP) has been nationally reimbursed in Japan since June 2019. Less than 10% of the patients have been reported to undergo recommended treatment. Todai OncoPanel (TOP) is a dual DNA-RNA panel as well as a paired tumor-normal matched test. Two hundred patients underwent TOP as part of Advanced Medical Care B with approval from the Ministry of Health, Labour and Welfare between September 2018 and December 2019. Tests were carried out in patients with cancers without standard treatment or when patients had already undergone standard treatment. Data from DNA and RNA panels were analyzed in 198 and 191 patients, respectively. The percentage of patients who were given therapeutic or diagnostic recommendations was 61% (120/198). One hundred and four samples (53%) harbored gene alterations that were detected with the DNA panel and had potential treatment implications, and 14 samples (7%) had a high tumor mutational burden. Twenty-two samples (11.1%) harbored 30 fusion transcripts or MET exon 14 skipping that were detected by the RNA panel. Of those 30 transcripts, 6 had treatment implications and 4 had diagnostic implications. Thirteen patients (7%) were found to have pathogenic or likely pathogenic germline variants and genetic counseling was recommended. Overall, 12 patients (6%) received recommended treatment. In summary, patients benefited from both TOP DNA and RNA panels while following the same indication as the approved CGP tests. (UMIN000033647).

Intraperitoneal paclitaxel combined with FOLFOX/CAPOX plus bevacizumab for colorectal cancer with peritoneal carcinomatosis (the iPac-02 trial): study protocol of a single arm, multicenter, phase 2 study.

BACKGROUND: The safety of intraperitoneally administrated paclitaxel (op PTX) was demonstrated in the phase I trial of ip PTX combined with conventional systemic chemotherapy for colorectal cancer with peritoneal carcinomatosis. Moreover, the median survival time was 29.3 months, which was longer than that observed in previous studies. Here, we planned the phase II trial of ip PTX: the iPac-02 trial. METHODS: This multicenter, open-label, single assignment interventional clinical study includes patients with colorectal cancer with unresectable peritoneal carcinomatosis. FOLFOX-bevacizumab or CAPOX-bevacizumab is administered concomitantly as systemic chemotherapy. PTX 20 mg/m2 is administered weekly through the peritoneal access port in addition to these conventional systemic chemotherapies. The response rate is the primary endpoint. Progression-free survival, overall survival, peritoneal cancer index improvement rate, rate of negative peritoneal lavage cytology, safety, and response rate to peritoneal metastases are the secondary endpoints. A total of 38 patients are included in the study. In the interim analysis, the study will continue to the second stage if at least 4 of the first 14 patients respond to the study treatment. The study has been registered at the Japan Registry of Clinical Trials (jRCT2031220110). RESULTS: We previously conducted phase I trial of ip PTX combined with conventional systemic chemotherapy for colorectal cancer with peritoneal carcinomatosis [1]. In the study, three patients underwent mFOLFOX, bevacizumab, and weekly ip PTX, and the other three patients underwent CAPOX, bevacizumab, and weekly ip PTX treatment. The dose of PTX was 20 mg/m [2]. The primary endpoint was the safety of the chemotherapy, and secondary endpoints were response rate, peritoneal cancer index improvement rate, rate of negative peritoneal lavage cytology, progression-free survival, and overall survival. Dose limiting toxicity was not observed, and the adverse events of ip PTX combined with oxaliplatin-based systemic chemotherapy were similar to those described in previous studies using systemic chemotherapy alone [3, 4]. The response rate was 25%, peritoneal cancer index improvement rate was 50%, and cytology in peritoneal lavage turned negative in all the cases. The progression-free survival was 8.8 months (range, 6.8-12 months), and median survival time was 29.3 months [5], which was longer than that observed in previous studies. CONCLUSION: Here, we planned the phase II trial of ip paclitaxel combined with conventional chemotherapy for colorectal cancer with peritoneal carcinomatosis: the iPac-02 trial.

The clinical impacts of postoperative complications after colon cancer surgery for the clinical course of adjuvant treatment and survival.

AIM: We investigated whether or not postoperative complications (POCs) themselves have a negative survival impact or indirectly worsen the survival due to insufficient adjuvant chemotherapy in a pooled analysis of two large phase III studies performed in Japan PATIENTS AND METHODS: The study examined the patients who enrolled in 1304, phase III study comparing the efficacy of 6 and 12 months of capecitabine as adjuvant chemotherapy for stage III colon cancer patients and in 882, a phase III study to confirm the tolerability of oxaliplatin, fluorouracil, and l-leucovorin in Japanese stage II/III colon cancer patients. In our study, POCs were defined as the following major surgical complications: anastomotic leakage, pneumonia, bowel obstruction/ileus, surgical site infection, postoperative bleeding, urinary tract infection, and fistula. Patients were classified as those with POCs (C group) and those without POCs (NC group). RESULTS: A total of 2095 patients were examined in the present study. POCs were observed in 169 patients (8.1%). The overall survival (OS) rates at 5 years after surgery were 75.3% in the C group and 86.5% in the NC group (p = 0.0017). The hazard ratio of POCs for the OS in multivariate analysis was 1.70 (95% confidence interval, 1.19 to 2.45; p = 0.0040). The time to adjuvant treatment failure (TTF) of adjuvant chemotherapy was similar between the groups, being 68.6% in the C group and 67.1% in the NC group for the 6-month continuation rate of adjuvant chemotherapy. The dose reduction rate of adjuvant chemotherapy and adjuvant treatment suspension rate were also similar between the groups (C vs. NC groups: 45.0% vs. 48.7%, p = 0.3520; and 52.7% vs. 55.0%, p = 0.5522, respectively). CONCLUSION: POCs were associated with a poor prognosis but did not affect the intensity of adjuvant chemotherapy. These results suggested that POCs themselves negatively influence the survival.

Blood levels of nicotinic acid negatively correlate with hearing ability in healthy older men.

BACKGROUND: Age-related hearing loss (ARHL) is a common phenomenon observed during aging. On the other hand, the decrease in Nicotinamide adenine dinucleotide (NAD +) levels is reported to be closely related to the age-related declines in physiological functions such as ARHL in animal studies. Moreover, preclinical studies confirmed NAD + replenishment effectively prevents the onset of age-related diseases. However, there is a paucity of studies on the relationship between NAD+ metabolism and ARHL in humans. METHODS: This study was analyzed the baseline results of our previous clinical trial, in which nicotinamide mononucleotide or placebo was administered to 42 older men (Igarashi et al., NPJ Aging 8:5, 2022). The correlations between blood levels of NAD+-related metabolites at baseline and pure-tone hearing thresholds at different frequencies (125, 250, 500, 1000, 2000, 4000, and 8000 Hz) in 42 healthy Japanese men aged > 65 years were analyzed using Spearman's rank correlation. Multiple linear regression analysis was performed with hearing thresholds as the dependent variable and age and NAD+-related metabolite levels as independent variables. RESULTS: Positive associations were observed between levels of nicotinic acid (NA, a NAD+ precursor in the Preiss-Handler pathway) and right- or left-ear hearing thresholds at frequencies of 1000 Hz (right: r = 0.480, p = 0.001; left: r = 0.422, p = 0.003), 2000 Hz (right: r = 0.507, p < 0.001, left: r = 0.629, p < 0.001), and 4000 Hz (left: r = 0.366, p = 0.029). Age-adjusted multiple linear regression analysis revealed that NA was an independent predictor of elevated hearing thresholds (1000 Hz (right): p = 0.050, regression coefficient (ß) = 1610; 1000 Hz (left): p = 0.026, ß = 2179; 2000 Hz (right): p = 0.022, ß = 2317; 2000 Hz (left): p = 0.002, ß = 3257). Weak associations of nicotinic acid riboside (NAR) and nicotinamide (NAM) with hearing ability were observed. CONCLUSIONS: We identified negative correlations between blood concentrations of NA and hearing ability at 1000 and 2000 Hz. NAD+ metabolic pathway might be associated with ARHL onset or progression. Further studies are warranted. TRIAL REGISTRATION: The study was registered at UMIN-CTR (UMIN000036321) on 1st June 2019.

Distribution of the follicular and luteal phase lengths and their age-dependent changes in Japanese women: A large population study.

Purpose: The current definition of menstrual cycle length in a Japanese woman is different from those of WHO definition, and the original data are outdated. We aimed to calculate the distribution of follicular and luteal phases length in modern Japanese women with various menstrual cycles. Methods: This study determined the lengths of the follicular and luteal phases of Japanese women using basal body temperature data collected via a smartphone application from 2015 to 2019, and the data were analyzed using the Sensiplan method. Over 9 million temperature readings from more than 80 000 participants were analyzed. Results: The mean duration of the low-temperature (follicular) phase averaged 17.1 days and was shorter among participants aged 40-49 years. The mean duration of the high-temperature (luteal) phase was 11.8 days. The variance and maximum-minimum difference of the length of the low temperature period were significant in women under 35 years old than women aged more than 35 years. Conclusions: The shortening of the follicular phase in women aged 40-49 years implied a relationship with the rapid decline of ovarian reserve in these women, and the age 35 years old was turning point of ovulatory function.

Predictors of rituximab effect on modified Rodnan skin score in systemic sclerosis: a machine-learning analysis of the DesiReS trial.

OBJECTIVES: The double-blind, parallel-group comparison, investigators initiated phase II clinical trial of IDEC-C2B8 (Rituximab) in patients with Systemic sclerosis (DesiReS) trial showed that rituximab is effective in treating skin sclerosis in SSc. However, which patient groups are likely to benefit from rituximab is unknown. METHODS: We performed post-hoc analysis of prospective data from 54 patients who received rituximab or placebo in the DesiReS trial. Twenty-seven baseline factors were used to investigate subpopulations with different magnitudes of rituximab effect on modified Rodnan skin score (mRSS) change at 24 weeks. Based on a machine-learning algorithm called the causal tree, we explored the combination of predictors needed to identify subpopulations that would respond to rituximab and have good treatment outcomes. RESULTS: Three factors were identified as branches of the decision tree: peripheral blood CD19-positive cell counts', 'mRSS', and 'serum surfactant protein D (SP-D) levels'. It was only in the subpopulation of patients with CD19-positive cell counts of <57/µl that rituximab did not show a significant improvement in mRSS vs placebo. In the subpopulation of patients with CD19-positive cell counts of ≥57/µl and mRSS ≥ 17, mRSS was most improved with rituximab [difference -17.06 (95% CI: -24.22, -9.89)]. The second greatest improvement in mRSS with rituximab was in the subpopulation with CD19-positive cell counts of ≥57/µl, mRSS < 17, and serum SP-D levels of ≥151 ng/ml [difference -10.35 (95% CI: -14.77, -5.93)]. CONCLUSION: SSc patients who have high CD19-positive cell counts and high mRSS are expected to have greater improvement in mRSS with rituximab. When the patients with high CD19-positive cell counts show low mRSS, serum SP-D levels may modify the treatment effect.

Incidence of and risk factors for self-load-related and medical device-related pressure injuries in critically ill patients: A prospective observational cohort study.

There are two types of pressure injuries: self-load-related pressure injuries (PIs) and medical device-related pressure injuries (MDRPIs), but the differences in risk factors between PIs and MDRPIs have not yet been clarified. If risk factors for PIs and MDRPIs differ, preventive interventions should take this into account. This is a prospective cohort study aimed to determine the cumulative incidence of PIs and MDRPIs in critically ill patients and to identify corresponding risk factors. The study included 1418 patients who were admitted to the critical care medical center of a single university hospital in Tokyo, Japan, between 1 December 2019 and 31 August 2020. The Kaplan-Meier method was used to calculate the cumulative incidence of PIs and MDRPIs. Furthermore, the Cox proportional hazards model was used to analyse the predictors in both the PI and MDRPI incidence and non-incidence groups. Predictors were based on data from the 0th disease day. The cumulative incidence of PIs and MDRPIs was 4.6/1000 person-days and 3.6/1000 person-days, respectively. Multivariate analysis using the Cox proportional hazards model showed that common risk factors for the occurrence of PIs and MDRPIs were possession of PI on admission, higher blood lactate, blood purification therapy, and positional restriction. The risk factors for PIs only were diabetes mellitus, septic shock, and a lower serum albumin level, while the risk factors for MDRPIs only were the D-dimer level and extracorporeal membranous oxygenation treatment. Therefore, prophylactic interventions need to consider these different risk factors.

Development and validation of an infant facial skin assessment tool: a prospective observational study.

BACKGROUND: Severe infant eczema on the face should be treated early because it may lead to allergic diseases in the future. However, caregivers find it difficult to assess. A visual tool for caregivers is needed to easily determine infants' facial skin condition severity based on the tool's scores. We developed an infant facial skin assessment tool (IFSAT) and evaluated its reliability and validity. METHODS: The IFSAT draft was developed based on results of a previous literature review and qualitative sketch. Panels including medical professionals and a caregiver checked the draft's content and face validity, and the IFSAT was finalized. To test the IFSAT's reliability and validity, caregivers and one-month-old infants were recruited. Two scoring methods were additionally created based on the relation between the items and cure period. The relationships between scores and cure period, and the ability to predict whether the infant needed medical treatment were examined by each scoring method. For the predictive validity, scores for infants requiring medical treatment and those for infants who did not were also compared. For the intra-examiner reliability analysis, two pediatricians rated the scores separately twice using photographs. Inter-rater reliabilities were analyzed among pediatricians, nurses, and caregivers. RESULTS: Altogether, 113 infant-caregiver pairs participated in the testing phase. Of the two scoring methods created (versions 1 and 2), pediatricians' and caregivers' scores using versions 1 and 2 were related to the cure period. These scores predict whether the infant needed medical treatment. We then selected version 2 based on the medical professionals' opinions. The scores of caregivers of infants requiring medical treatment were higher than those of caregivers of infants not requiring treatment (p < 0.001). The intraclass correlation coefficient (ICC) of intra-examiner reliability was 0.87. The ICC of inter-rater reliabilities between pediatricians' and caregivers' scores and between nurses' and caregivers' scores were 0.66, and 0.66, respectively. CONCLUSIONS: The proposed IFSAT may be used to assess whether infants need medical treatment and whether to extend the cure period. The tool's reliability and validity were confirmed.

Association of Genetic Polymorphism with Taxane-induced Peripheral Neuropathy: Sub-analysis of a Randomized Phase II Study to Determine the Optimal Dose of 3-week Cycle Nab-Paclitaxel in Metastatic Breast Cancer Patients.

Chemotherapy-induced peripheral neuropathy (CIPN) is an important clinical challenge that threatens patients' quality of life. This sub-study of the ABROAD trial investigated the influence of single nucleotide polymorphisms (SNPs) on CIPN, using genotype data from a randomized study to determine the optimal dose of a 3-week-cycle regimen of nab-paclitaxel (q3w nab-PTX) in patients with metastatic breast cancer (MBC). Patients with HER2-negative MBC were randomly assigned to three doses of q3w nab-PTX (SD: 260 mg/m2 vs. MD: 220 mg/m2 vs. LD: 180 mg/m2). Five SNPs (EPHA4-rs17348202, EPHA5-rs7349683, EPHA6-rs301927, LIMK2-rs5749248, and XKR4-rs4737264) were analyzed based on the results of a previous genome-wide association study. Per-allele SNP associations were assessed by a Cox regression to model the cumulative dose of nab-PTX up to the onset of severe or worsening sensory neuropathy. A total of 141 patients were enrolled in the parent study; 91(65%) were included in this sub-study. Worsening of CIPN was significantly greater in the cases with XKR4 AC compared to those with a homozygote AA (HR 1.86, 95%CI: 1.00001-3.46, p=0.049). There was no significant correlation of CIPN with any other SNP. A multivariate analysis showed that the cumulative dose of nab-PTX was most strongly correlated with CIPN (p<0.01).

Secondary endpoints analysis in patients with estrogen receptor-positive metastatic breast cancer treated with everolimus and exemestane enrolled in Oral Care-BC.

BACKGROUND: The Oral Care BC-trial reported that professional oral care (POC) reduces the incidence and severity of oral mucositis in patients receiving everolimus (EVE) and exemestane (EXE). However, the effect of POC on clinical response among patients receiving EVE and EXE was not established. We compared outcomes for estrogen receptor-positive metastatic breast cancer patients who received POC to those who had not, and evaluated clinical prognostic factors. All patients simultaneously received EVE and EXE. METHODS: Between May 2015 and Dec 2017, 174 eligible patients were enrolled in the Oral Care-BC trial. The primary endpoint was the comparative incidence of grade 1 or worse oral mucositis, as evaluated for both the groups over 8 weeks by an oncologist. The secondary endpoints were progression-free survival (PFS) and overall survival (OS). Data were collected after a follow-up period of 13.9 months. RESULTS: There were no significant differences in PFS between the POC and Control Groups (P = 0.801). A BMI <  25 mg/m2 and non-visceral metastasis were associated with longer PFS (P = 0.018 and P = 0.003, respectively) and the use of bone modifying agents (BMA) was associated with shorter PFS (P = 0.028). The PFS and OS between the POC and control groups were not significantly different in the Oral-Care BC trial. CONCLUSIONS: POC did not influence the prognosis of estrogen receptor-positive metastatic breast cancer patients. Patients with non-visceral metastasis, a BMI <  25 mg/m2, and who did not receive BMA while receiving EVE and EXE may have better prognoses. TRIAL REGISTRATION: The study protocol was registered online at the University Hospital Medical Information Network (UMIN), Japan (protocol ID 000016109), on January 5, 2015 and at ClinicalTrials.gov ( NCT02376985 ).

Impact of hepatitis C virus on survival in patients undergoing resection of intrahepatic cholangiocarcinoma: Report of a Japanese nationwide survey.

AIM: We reviewed the data of a nationwide follow-up survey to determine the impact of hepatitis C virus (HCV) infection on the outcomes of hepatectomy for mass-forming (MF) type, and combined mass-forming and periductal infiltrating (MF + PI) type intrahepatic cholangiocarcinoma (ICC). METHODS: In total, 956 patients with ICC who underwent curative hepatic resection were included in this cohort study, and patients were classified according to virus status. Patients were classified according to virus status as follows: HCV-related ICC (n = 138, 14.4%), hepatitis B virus (HBV)-related ICC (n = 43, 4.5%) and non-virus-related ICC (n = 775, 81.1%). To control for variables, we used 1:1 propensity score-matching to compare outcomes after surgery between HCV-related (n = 102) and non-virus-related ICC cases (n = 102). RESULTS: We successfully matched HCV-related and non-virus-related ICC cases with similar liver function and tumor characteristics. Patients with HCV-related ICC had significantly shorter recurrence-free survival (hazard ratio 0.62, 95% confidence interval 0.42-0.92, p = 0.016) and overall survival (hazard ratio: 0.57, 95% confidence interval: 0.37-0.88, p = 0.011) than patients with non-virus-related ICC. Cox proportional hazard analysis showed that HCV-related ICC offered a worse prognosis than non-virus-related ICC. CONCLUSIONS: HCV infection increases the risk of recurrence and worsens overall survival in patients after curative resection for MF and combined MF + PI type ICC.

Clinical outcomes and predictive value of programmed cell death-ligand 1 expression in response to anti-programmed cell death 1/ligand 1 antibodies in non-small cell lung cancer patients with performance status 2 or greater.

BACKGROUND: Anti-programmed cell death protein-1/ligand-1 (anti-PD-1/PD-L1) therapy is promising for patients with non-small-cell lung cancer (NSCLC); however, clinical trials have focused on patients with a performance status (PS) 0 or 1. This study aimed to evaluate the clinical outcomes and correlation between PD-L1 expression status and tumor response to anti-PD-1/PD-L1 therapy among NSCLC patients with poor PS (i.e., PS ≥ 2). METHODS: In total, 130 patients with NSCLC and PS ≥ 2 treated with anti-PD-1/PD-L1 monotherapy at 12 institutions between January 2016 and August 2019 were retrospectively reviewed. PD-L1 expression status was divided into four groups: < 1%, 1-49%, ≥ 50%, and unknown. RESULTS: The objective response rate and PS improvement rate were 23 and 21% and were higher in the PD-L1 ≥ 50% group than in other groups (P < 0.01). Median progression-free survival (PFS) was 62 days and was longer in the PD-L1 ≥ 50% group than in other groups (P = 0.03). Multivariate analyses revealed that PD-L1 expression is significantly associated with prolonged PFS (PD-L1 < 1%; reference; 1-49%, hazard ratio [HR] 0.19, 95% confidence interval [CI] 0.04-0.99, P = 0.05; ≥ 50%, HR 0.12, 95% CI 0.02-0.71, P = 0.02; unknown, HR 0.30, 95% CI 0.08-1.22, P = 0.09). CONCLUSIONS: NSCLC patients with poor PS and PD-L1 ≥ 50% are expected to benefit from anti-PD-1/PD-L1 therapy, despite a modest overall response among NSCLC patients with poor PS. Accordingly, PD-L1 expression provides useful information regarding decision-making for anti-PD-1/PD-L1 therapy even in these populations.

Liver Resection for Multiple Hepatocellular Carcinomas: A Japanese Nationwide Survey.

OBJECTIVE: The aim of the study was to evaluate the survival benefits of liver resection (LR) compared with transarterial chemoembolization (TACE) for patients with multiple hepatocellular carcinomas (HCCs). BACKGROUND: Despite significant improvements in diagnostic imaging and the widespread application of screening programs, some patients with HCC continue to present with multiple tumors. The surgical indications for multiple HCCs remain controversial. METHODS: Among 77,268 patients with HCC reported in a Japanese nationwide survey, 27,164 patients had multiple HCCs. The exclusion criteria were Child-Pugh B/C, treatment other than LR and TACE, >3 tumors, and insufficient available data. Ultimately, 3246 patients (LR: n = 1944, TACE: n = 1302) were included. The survival benefit of LR for patients multiple HCCs was evaluated by using propensity score matching analysis. RESULTS: The study group of 2178 patients (LR: n = 1089, TACE: n = 1089) seemed to be well matched. The overall survival rate in the LR group was 60.0% at 5 years, which was higher than that in the TACE group (41.6%, P < 0.001). Among patients with a tumor size of 30 mm or more, LR showed a survival benefit over TACE at 5 years (53.0% vs 32.7%, P < 0.001). The multivariate analysis indicated that age, serum albumin level, serum alpha-fetoprotein (AFP) level, macrovascular invasion, tumor size, and TACE were independent predictors of poor prognosis in multiple HCCs. CONCLUSIONS: LR could offer better long-term survival than TACE for patients with multiple HCCs (up to 3 tumors). If patients have good liver function (Child-Pugh A), LR is recommended, even for those with multiple HCCs with tumor sizes of 30 mm or more.

Oral Care Evaluation to Prevent Oral Mucositis in Estrogen Receptor-Positive Metastatic Breast Cancer Patients Treated with Everolimus (Oral Care-BC): A Randomized Controlled Phase III Trial.

BACKGROUND: The incidence of oral mucositis (any grade) after everolimus treatment is 58% in the general population and 81% in Asian patients. This study hypothesized that professional oral care (POC) before everolimus treatment could reduce the incidence of everolimus-induced oral mucositis. MATERIALS AND METHODS: This randomized, multicenter, open-label, phase III study evaluated the efficacy of POC in preventing everolimus-induced mucositis. Patients were randomized into POC and control groups (1:1 ratio) and received everolimus with exemestane. Patients in the POC group underwent teeth surface cleaning, scaling, and tongue cleaning before everolimus initiation and continued to receive weekly POC throughout the 8-week treatment period. Patients in the control group brushed their own teeth and gargled with 0.9% sodium chloride solution or water. The primary endpoint was the incidence of all grades of oral mucositis. We targeted acquisition of 200 patients with a 2-sided type I error rate of 5% and 80% power to detect 25% risk reduction. RESULTS: Between March 2015 and December 2017, we enrolled 175 women from 31 institutions, of which five did not receive the protocol treatment and were excluded. Over the 8 weeks, the incidence of grade 1 oral mucositis was significantly different between the POC group (76.5%, 62 of 82 patients) and control group (89.7%, 78 of 87 patients; p = .034). The incidence of grade 2 (severe) oral mucositis was also significantly different between the POC group (34.6%, 28 of 82 patients) and control group (54%, 47 of 87 patients; p = .015). As a result of oral mucositis, 18 (22.0%) patients in the POC group and 28 (32.2%) in the control group had to undergo everolimus dose reduction. CONCLUSION: POC reduced the incidence and severity of oral mucositis in patients receiving everolimus and exemestane. This might be considered as a treatment option of oral care for patients undergoing this treatment. Clinical trial identification number: NCT02069093. IMPLICATIONS FOR PRACTICE: The Oral Care-BC trial that prophylactically used professional oral care (POC), available worldwide, did not show a greater than 25% difference in mucositis. The 12% difference in grade 1 or higher mucositis and especially the ∼20% difference in grade 2 mucositis are likely clinically meaningful to patients. POC before treatment should be considered as a treatment option of oral care for postmenopausal patients who are receiving everolimus and exemestane for treatment of hormone receptor-positive, HER2-negative advanced breast cancer and metastatic breast cancer. However, POC was not adequate for prophylactic oral mucositis in these patients, and dexamethasone mouthwash prophylaxis is standard treatment before everolimus.

Chemotherapy should be performed in epidermal growth factor receptor mutation-positive lung adenocarcinoma patients who had progressive disease to the first epidermal growth factor receptor-tyrosine kinase inhibitor.

After the failure of first-line epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) therapy, some non-small cell lung cancer patients desire to receive switching with another EGFR-TKI (TKI-switching), although cytotoxic chemotherapy has been recommended as second-line therapy. It is unclear who should not receive TKI-switching in these patients. We retrospectively evaluated overall survival (OS) from the initiation of first EGFR-TKI (first-TKI) therapy in advanced lung adenocarcinoma patients with active EGFR mutations (deletion of exon 19 or L858R in exon 21) who received TKI-switching according to the best response of the first-TKI. There was no difference in the OS between patients receiving TKI-switching (n = 35) and patients receiving additional chemotherapy between the first-TKI and second-TKI therapy (n =10) (P = 0.614). Among patients receiving TKI-switching, the OS in cases with progressive disease to the first-TKI (n = 9) was shorter than that in cases with disease control to the first-TKI (n = 26) (12.7 months vs. 49.4 months, P < 0.001). Five of the nine progressive disease cases who received TKI-switching missed an opportunity to receive chemotherapy. Their OS tended to be shorter than that in patients who received chemotherapy during the whole period of anticancer therapy (12.2 months vs. 20.3 months, P = 0.060). The multivariate analysis showed that disease control to the first-TKI therapy (P = 0.005) or the presence of chemotherapy (P = 0.087) decreased the risk of mortality. Chemotherapy should be performed in patients with progressive disease to the first-TKI.

Timing of resumption of immune checkpoint inhibitor therapy after successful control of immune-related adverse events in seven advanced non-small cell lung cancer patients.

Among advanced non-small cell lung cancer (NSCLC) patients in whom grade 2/3 immune-related adverse events (irAEs) that had developed during the initial immune checkpoint inhibitor (ICI) therapy had been successfully controlled, we experienced three patients in whom ICI therapy was resumed at the diagnosis of progressive disease (PD group, n = 3) and four patients in whom it was resumed immediately after successful control of irAEs (non-PD group, n = 4). The tumor response rate, disease control rate to the resumed ICI and progression-free survival from the resumption of ICI therapy were 0%, 0% and 2 months in the PD group and 25%, 75% and 4.8 months in the non-PD group. In advanced NSCLC patients in whom resumption of discontinued ICI therapy was planned, the ICI therapy should be resumed immediately after successful control of irAEs, rather than at the diagnosis of PD.

Longitudinal effects of a nationwide lifestyle intervention program on cardiometabolic outcomes in Japan: An observational cohort study.

The Japanese government launched a nationwide health screening and lifestyle intervention program in 2008 to prevent and reduce metabolic syndrome in at-risk individuals. This study examined the longitudinal effects of the program's lifestyle interventions on metabolic outcomes using health insurance data from one prefecture. The study population comprised 16,317 individuals aged 40-74 years who met the recommendation criteria for the interventions between 2009 and 2015. Participants were categorized into an overall intervention group (comprising a single-session motivational intervention group and a multi-session intensive intervention group) and a non-intervention group. We evaluated the interventions' effects on the initiation of medications for metabolic disorders (hyperlipidemia, hypertension, and hyperglycemia) and metabolic syndrome incidence for 6 years using discrete hazard models that adjusted for sex, age, health screening measurements, and smoking habit. The longitudinal effects on health screening measurements were also evaluated using regression models for repeated measures. The adjusted hazard ratios (aHRs) (95% confidence interval [CI]) for initiation of medications were 0.83 (0.77-0.90), 0.77 (0.71-0.84), and 0.66 (0.57-0.77) for overall, motivational, and intensive interventions, respectively. The aHRs (95%CI) for metabolic syndrome incidence were 0.84 (0.75-0.94), 0.80 (0.71-0.91), and 0.67 (0.51-0.89) for overall, motivational, and intensive interventions, respectively. The interventions reduced body mass index and waist circumference, but had modest effects on blood lipids, blood glucose, and hemoglobin A1c levels; blood pressure was unaffected. These interventions represent an effective strategy to prevent the progression of preclinical metabolic syndrome, but further studies are needed to evaluate their long-term preventive effects on cardiovascular disease and diabetes.
