Pooled Analysis of Studies Evaluating Fosnetupitant and Risk Factors for Cisplatin-Induced Nausea and Vomiting During the Extended Overall Phase.

INTRODUCTION: Fosnetupitant is a novel neurokinin 1 receptor antagonist (NK1RA) with favorable antiemetic efficacy in patients receiving emetogenic chemotherapy. This study assessed the efficacy of fosnetupitant in combination with palonosetron and dexamethasone and identified risk factors for chemotherapy-induced nausea and vomiting (CINV) for up to 168 h after treatment using pooled data from Japanese studies. METHODS: A pooled analysis of randomized phase II and phase III studies was performed to compare the efficacy of fosnetupitant and fosaprepitant in patients receiving cisplatin-based chemotherapy. The complete response (CR; no vomiting and no rescue medication) rate, CINV risk factors in various phases (0-120, 0-168, and 120-168 h), and impact of the number of risk factors on the time to treatment failure (TTF) were examined in the overall and NK1RA evaluable populations. RESULTS: In the combined cohort of NK1RA evaluable patients (n = 980), the CR rate at 0-168 h was significantly better in the fosnetupitant 235 mg group than in the fosaprepitant group (rate difference = 6.8%, 95% confidence interval = 1.0-12.7, p = 0.022). In the overall (n = 1368) and NK1RA evaluable populations, the CINV risk factor at 120-168 h was treatment failure in the first 120 h. TTF deteriorated as the number of identified CINV risk factors increased. CONCLUSION: This analysis revealed that fosnetupitant could have long-acting antiemetic potency (> 120 h) and indicated the importance of antiemetic therapy at 0-120 h for CINV up to 168 h after chemotherapy.

First-line nivolumab, paclitaxel, carboplatin, and bevacizumab for advanced non-squamous non-small cell lung cancer: Updated survival analysis of the ONO-4538-52/TASUKI-52 randomized controlled trial.

BACKGROUND: ONO-4538-52/TASUKI-52 was performed in Japan, Korea, and Taiwan to determine the oncological effectiveness and safety of combining nivolumab or placebo with bevacizumab plus platinum chemotherapy for the initial (first-line) treatment of patients with advanced non-squamous non-small cell lung cancer (nsNSCLC). At the interim analysis (minimum follow-up, 7.4 months), the independent radiology review committee-assessed progression-free survival was significantly longer in the nivolumab arm, but overall survival (OS) data were immature. METHODS: Here, we present the updated OS data. Patients with treatment-naïve stage IIIB/IV or recurrent nsNSCLC without driver mutations in ALK, EGFR, or ROS1, were randomized 1:1 to receive either nivolumab or placebo. Patients in both arms received paclitaxel, carboplatin, and bevacizumab, administered 3-weekly for a maximum of 6 cycles. Nivolumab/placebo and bevacizumab were subsequently continued until disease progression or unacceptable toxicity. RESULTS: Overall, 550 patients were randomized. At the time of the analysis (minimum follow-up: 19.4 months), the median OS was longer in the nivolumab arm than in the placebo arm (30.8 vs. 24.7 months; hazard ratio 0.74, 95% confidence interval 0.58-0.94). The 12-month OS rates were 81.3% vs. 76.3% in the nivolumab vs. placebo arms, respectively. The respective 18-month OS rates were 69.0% vs. 61.9%. CONCLUSION: Nivolumab plus platinum chemotherapy and bevacizumab demonstrated longer OS vs. the placebo combination. We believe this regimen is viable as a standard, first-line treatment for patients with advanced nsNSCLC without driver mutations in ALK, EGFR, or ROS1.

Multi-Institutional Randomized Phase II Trial of Gefitinib for Previously Treated Patients With Advanced Non-Small-Cell Lung Cancer.

PURPOSE: To evaluate the efficacy and tolerability of two doses of gefitinib (Iressa [ZD1839]; AstraZeneca, Wilmington, DE), a novel epidermal growth factor receptor tyrosine kinase inhibitor, in patients with pretreated advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: This was a randomized, double-blind, parallel-group, multicenter phase II trial. Two hundred ten patients with advanced NSCLC who were previously treated with one or two chemotherapy regimens (at least one containing platinum) were randomized to receive either 250-mg or 500-mg oral doses of gefitinib once daily. RESULTS: Efficacy was similar for the 250- and 500-mg/d groups. Objective tumor response rates were 18.4% (95% confidence interval [CI], 11.5 to 27.3) and 19.0% (95% CI, 12.1 to 27.9); among evaluable patients, symptom improvement rates were 40.3% (95% CI, 28.5 to 53.0) and 37.0% (95% CI, 26.0 to 49.1); median progression-free survival times were 2.7 and 2.8 months; and median overall survival times were 7.6 and 8.0 months, respectively. Symptom improvements were recorded for 69.2% (250 mg/d) and 85.7% (500 mg/d) of patients with a tumor response. Adverse events (AEs) at both dose levels were generally mild (grade 1 or 2) and consisted mainly of skin reactions and diarrhea. Drug-related toxicities were more frequent in the higher-dose group. Withdrawal due to drug-related AEs was 1.9% and 9.4% for patients receiving gefitinib 250 and 500 mg/d, respectively. CONCLUSION: Gefitinib showed clinically meaningful antitumor activity and provided symptom relief as second- and third-line treatment in these patients. At 250 mg/d, gefitinib had a favorable AE profile. Gefitinib 250 mg/d is an important, novel treatment option for patients with pretreated advanced NSCLC.

Findings of virtual bronchoscopic navigation can predict the diagnostic rate of primary lung cancer by bronchoscopy in patients with peripheral lung lesions.

BACKGROUND: Despite being minimally invasive, bronchoscopy does not always result in pathological specimens being obtained. Therefore, we investigated whether virtual bronchoscopic navigation (VBN) findings were associated with the rate of diagnosis of primary lung cancer by bronchoscopy in patients with peripheral lung lesions. METHODS: This study included patients with suspected malignant peripheral lung lesions who underwent bronchoscopy at St. Luke's International Hospital between October 2013 and March 2020. Patients diagnosed with primary lung cancer were grouped according to whether their pathology could be diagnosed by bronchoscopy, and their clinical factors were compared. In addition, the distance between the edge of the lesion and the nearest branch ("distance by VBN") was calculated. The distance by VBN and various clinical factors were compared with the diagnostic rates of primary lung cancer. RESULTS: The study included 523 patients with 578 lesions. After excluding 55 patients who underwent multiple bronchoscopies, 381 patients were diagnosed with primary lung cancer. The diagnostic rate by bronchoscopy was 71.1% (271/381). Multivariate analysis revealed that the lesion diameter (odds ratio [OR] 1.107), distance by VBN (OR 0.94) and lesion structure (solid lesion or ground-glass nodule; OR 2.988) influenced the risk of a lung cancer diagnosis. The area under the receiver operating characteristic curve for diagnosis based on lesion diameter and distance by VBN was 0.810. CONCLUSION: The distance by VBN and lesion diameter were predictive of the diagnostic rates of primary lung cancer by bronchoscopy in patients with peripheral lung lesions.

Exploratory Analysis Comparing Fosnetupitant Versus Fosaprepitant for Prevention of Highly Emetogenic Chemotherapy-Induced Nausea and Vomiting (CINV): A Randomized, Double-Blind, Phase 3 Study (CONSOLE).

INTRODUCTION: We describe the results of an exploratory analysis performed on the first head-to-head study (JapicCTI-194611) comparing two different intravenous (IV) neurokinin 1 (NK1) receptor antagonists, fosnetupitant and fosaprepitant, in combination with palonosetron (PALO) and dexamethasone (DEX) for the prevention of highly emetogenic chemotherapy (HEC)-induced nausea and vomiting (CINV). This analysis was performed to validate the findings of the primary analysis (previously published) utilizing a last observation carried forward (LOCF) approach for missing values for the efficacy endpoint of complete response (no emetic event and no rescue medication), while also evaluating the time periods encompassing the 0-168-hour (h) "extended overall phase" interval. METHODS: Patients scheduled to receive cisplatin-based chemotherapy were randomized 1:1 to fosnetupitant 235 mg or fosaprepitant 150 mg in combination with PALO 0.75 mg and DEX. Complete response rates were calculated and compared (stratified by age category and sex with a Mantel-Haenszel test) during the study's primary overall phase (0-120 h) and during additional time intervals of interest [acute (0-24 h), delayed (24-120 h), extended delayed (> 24-168 h), beyond delayed (120-168 h), and extended overall (0-168 h)]. RESULTS: A total of 785 patients were included (fosnetupitant N = 392, fosaprepitant N = 393). Complete response rates were numerically higher for fosnetupitant versus fosaprepitant for all time intervals and statistically significant for the extended overall phase. Complete response rates for fosnetupitant versus fosaprepitant during the overall, acute, delayed, extended delayed, beyond delayed, and extended overall phases were 75.5% vs. 71.0% (p = 0.1530), 93.9% vs. 92.6% (p = 0.4832), 77.0% vs. 72.8% (p = 0.1682), 74.7% vs. 68.4% (p = 0.0506), 86.7% vs. 81.7% (p = 0.0523), and 73.5% vs. 66.9% (p = 0.0450), respectively. CONCLUSION: In this exploratory analysis, fosnetupitant appeared to be more effective than fosaprepitant in preventing CINV associated with cisplatin-based HEC during the extended 7-day period following chemotherapy.

A phase 3 safety study of fosnetupitant as an antiemetic in patients receiving anthracycline and cyclophosphamide: CONSOLE-BC.

BACKGROUND: Fosnetupitant (FosNTP), an intravenous neurokinin 1 receptor antagonist, demonstrated a favorable safety profile with a potentially low risk of injection site reactions (ISRs) and promising antiemetic efficacy in patients receiving cisplatin-based highly emetogenic chemotherapy in a previous phase 2 study. We conducted a randomized, double-blind safety study to evaluate the safety profile of FosNTP, including ISRs, in patients receiving doxorubicin-cyclophosphamide or epirubicin-cyclophosphamide (AC/EC) chemotherapy. METHODS: Patients scheduled to receive AC/EC were randomized 1:1 to receive 235 mg of FosNTP or 150 mg of fosaprepitant (FosAPR), both in combination with 0.75 mg of intravenous palonosetron and 9.9 mg of dexamethasone on day 1. The stratification factors were age category (<55 vs ≥55 years) and study site. The primary end point was the incidence of treatment-related adverse events (TRAEs) with FosNTP. RESULTS: Overall, 102 patients were randomized to FosNTP (n = 52) or FosAPR (n = 50), and all were treated with the study drug and evaluated for safety. The primary end point, the incidence of TRAEs, was similar with FosNTP (21.2%; 95% confidence interval [CI], 11.1%-34.7%) and FosAPR (22.0%; 95% CI, 11.5%-36.0%), with any-cause ISRs observed in 5.8% and 26.0% of patients, respectively, and treatment-related ISRs observed in 0% and 10.0%, respectively. The overall (0-120 hour) complete response (defined as no emetic event and no rescue medication) rate, standardized by age category in the full analysis set, was 45.9% (23 of 51 patients) with FosNTP and 51.3% (25 of 49 patients) with FosAPR. CONCLUSIONS: FosNTP demonstrated a favorable safety profile with a very low risk of ISRs in the AC/EC setting.

Bronchoscopy for the diagnosis of nontuberculous mycobacterial pulmonary disease: Specificity and diagnostic yield in a retrospective cohort study.

BACKGROUND: Bronchoscopy is a recognized method for obtaining specimens for the diagnosis of nontuberculous mycobacterial pulmonary disease (NTM-PD). However, its diagnostic properties remain to be elucidated. The aim of this study was to determine the specificity of bronchoscopy for the diagnosis of NTM-PD, and to examine the diagnostic yield of bronchoscopy for detecting nontuberculous mycobacteria (NTM) when patients cannot expectorate sputum with NTM. METHODS: This retrospective cohort study included 2657 patients who underwent bronchoscopy and mycobacterial culture between January 2004 and June 2018 in a tertiary care center in Tokyo, Japan. To examine the specificity of bronchoscopy, the first cohort comprised patients who underwent bronchoscopy for the diagnosis of lung cancer and mycobacterial culture. To investigate the diagnostic yield, patients with nodular bronchiectasis who underwent bronchoscopy for the diagnosis of NTM-PD were enrolled into the second cohort. RESULTS: In total, 919 patients were diagnosed with lung cancer, 19 patients showed positive culture for NTM, and 14 patients showed findings for NTM-PD. Accordingly, the specificity was calculated as 900/905 (99.4%). In addition, NTM-PD was suspected before bronchoscopy in 199 patients; the diagnostic yield was 105/199 (52.8%). Four factors were associated with NTM-PD: upper lobe examination, absence of specific bacteria, absence of connective tissue disease, and a higher total computed tomography score. CONCLUSIONS: Bronchoscopy has a high specificity for the diagnosis of NTM-PD. In addition, even when NTM is undetected in sputum, bronchoscopy may detect mycobacteria in approximately half of the patients suspected of having NTM-PD.

Randomized, Double-Blind, Phase III Study of Fosnetupitant Versus Fosaprepitant for Prevention of Highly Emetogenic Chemotherapy-Induced Nausea and Vomiting: CONSOLE.

PURPOSE: We evaluated the efficacy and safety of fosnetupitant (FosNTP) versus fosaprepitant (FosAPR) for preventing highly emetogenic chemotherapy-induced nausea and vomiting. This phase III study was the first head-to-head comparison between two different neurokinin-1 receptor antagonists in combination with palonosetron and dexamethasone. PATIENTS AND METHODS: Patients scheduled to receive cisplatin-based chemotherapy were randomly assigned 1:1 to FosNTP 235 mg or FosAPR 150 mg in combination with palonosetron 0.75 mg and dexamethasone. The primary end point was overall (0-120 hours) complete response (CR; no emetic event and no rescue medication) rate, stratified by sex and age category, to show the noninferiority of FosNTP to FosAPR (noninferiority margin, -10% for the difference in the overall CR rate). RESULTS: Overall, 795 patients were randomly assigned, of whom 785 received the study drug (FosNTP [N = 392] v FosAPR [N = 393]) and were evaluated for efficacy and safety. The overall CR rate was 75.2% versus 71.0%, respectively (Mantel-Haenszel common risk difference, 4.1%; 95% CI, -2.1% to 10.3%), demonstrating noninferiority of FosNTP to FosAPR. The CR rates in the acute (0-24 hours), delayed (24-120 hours), and beyond delayed (120-168 hours) phases, and at 0-168 hours were 93.9% versus 92.6%, 76.8% versus 72.8%, 86.5% versus 81.4%, and 73.2% versus 66.9%, respectively. The incidence rates of treatment-related adverse events with FosNTP versus FosAPR were 22.2% versus 25.4%, whereas adverse events or treatment-related adverse events relevant to injection site reactions were 11.0% versus 20.6% (P < .001) and 0.3% versus 3.6% (P < .001), respectively. CONCLUSION: FosNTP demonstrated noninferiority to FosAPR, with a favorable safety profile and lower risk for injection site reactions. Thus, FosNTP is valuable in the prophylaxis of acute, delayed, and beyond delayed chemotherapy-induced nausea and vomiting.

Pectoralis Muscle Mass on Chest CT at Admission Predicts Prognosis in Patients with Pneumonia.

Methods: A retrospective cohort study was performed in patients aged 18 years or older with pneumonia who underwent chest CT within 24 hours of admission between April 2014 and March 2019. We measured the thickness, area, and volume of the pectoralis major and minor muscles at the level of the aortic arch. Factors associated with mortality were examined using logistic regression analysis. Results: A total of 483 patients (mean age 77 ± 14 years, 300 men (62%)) were included, and fifty-one patients (11%) died during admission. In univariate analysis, decreased thickness, area, and volume of the pectoralis major and minor muscles were associated with higher in-hospital mortality. Multivariate analysis with adjustment for age, gender, serum albumin, and A-DROP revealed that thinner pectoralis major and minor muscles were independent factors of poor prognosis (odds ratio: 0.878, 95% confidence interval (CI): 0.783-0.985, P=0.026 and odds ratio: 0.842, 95% CI: 0.733-0.968, P=0.016, respectively). Approximately 25% of the patients died when the pectoralis minor muscle thickness was 5 mm or less, and no patients died when it was 15 mm or more. Conclusion: The pectoralis muscle mass may be an independent prognostic factor in hospitalized patients with pneumonia.

Bereaved Family Members' Perceived Care at the End of Life for Patients with Noncancerous Respiratory Diseases.

Background: Data regarding the quality of end-of-life care for patients with noncancerous illnesses are lacking. Objective: This study aimed to evaluate end-of-life care for patients with noncancerous respiratory disease from the perspective of bereaved family members and explore the factors associated with the quality of patient death and care. Design: This cross-sectional study included patients who had died of noncancerous respiratory disease in general wards of pulmonary department in Japan between 2014 and 2016 and conducted an anonymous self-report questionnaire survey for the patients' bereaved family members. Measurements: We evaluated overall satisfaction with care and the quality of death and end-of-life care using the Good Death Inventory (GDI) and Care Evaluation Scale (CES), respectively. A multiple linear regression analysis was performed to explore the factors associated with these outcomes. Results: In total, 130 questionnaires were distributed, and the effective response rate was 38% and 50 patients were included (median age: 82 [range 58-101] years; 37 men [74%]). Primary diagnoses at death included 29 cases of pneumonia (58%), 15 interstitial lung disease (30%), and 3 chronic obstructive pulmonary disease (6%). Of the bereaved family members, 26 (52%) were spouses, and 19 (38%) were children (median age [range]: 68 [33-102] years, 15 men [30%]). The overall CES and GDI scores (mean ± standard deviation) were 77 ± 15 and 79 ± 15, respectively. The presence of dementia was an independent factor associated with high CES and GDI scores in the multiple linear regression analysis. Conclusions: In patients who died of noncancerous respiratory disease, the presence of dementia could be associated with the higher quality of patient death and care. In dementia, an understanding of the terminal nature of this condition may lead to an appropriate end-of-life care.

High-resolution computed tomography for the prediction of mortality in acute respiratory distress syndrome: A retrospective cohort study.

BACKGROUND AND AIMS: Acute respiratory distress syndrome (ARDS) demonstrates several image patterns on high-resolution computed tomography (HRCT). The purpose of this study was to investigate the relationship between specific HRCT findings and the prognosis of ARDS. METHODS: This was a retrospective cohort study performed in a single hospital in Japan. We categorized HRCT findings into three distribution patterns: diffuse, subpleural sparing, and dorsal patterns. All patterns were assessed at three levels of each lung. Multivariable logistic regression analysis was used to identify parameters associated with in-hospital mortality. RESULTS: A total of 144 patients with ARDS (age: 72 ± 16 years, 112 men) were included in the study. The in-hospital mortality rate was 42% (survivors, n = 83; nonsurvivors, n = 61). Nonsurvivors were significantly older (70 ± 17 vs 76 ± 13, P = 0.01) and had lower serum albumin levels (P = 0.01), more traction bronchiectasis (P = 0.02), and more diffuse pattern (P < 0.001) than survivors. The presence of diffuse patterns was an independent adverse prognostic factor for predicting mortality (odds ratio, 1.32; 95% confidence interval [CI]: 1.08-1.61, P = 0.007). CONCLUSIONS: HRCT distribution patterns may predict mortality in ARDS patients.

Efficacy and Safety of S-1 Compared With Docetaxel in Elderly Patients With Advanced NSCLC Previously Treated With Platinum-Based Chemotherapy: A Subgroup Analysis of the EAST-LC Trial.

INTRODUCTION: Despite recent advances in NSCLC treatment, specific data on the elderly population remain limited. In this post hoc subgroup analysis of the East Asia S-1 Trial in Lung Cancer (EAST-LC) trial, we compared S-1 and docetaxel (DTX) in patients aged 70 years old and above with pretreated advanced NSCLC. METHODS: Patients were randomly assigned (1:1) to receive S-1 (orally, twice daily on d 1-28 of a 6-wk cycle) or DTX (intravenously, on d 1 of a 3-wk cycle). The initial S-1 dose was 80, 100, or 120 mg/day on the basis of body surface area, and the DTX doses were 60 mg/m2 (Japan) or 75 mg/m2 (outside Japan). The primary end point was overall survival, and secondary end points included progression-free survival, response rate, quality of life (QOL) using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core-30, and safety. RESULTS: Among 189 patients aged 70 years and above assessed as the full analysis set, baseline characteristics were generally similar between treatment arms. The median overall survival was 14.7 (S-1) versus 12.1 months (DTX); the hazard ratio was equal to 0.76, with a 95% confidence interval (CI) of 0.54-1.07. The median progression-free survival was similar in both arms (both 4.1 mo, hazard ratio = 0.84, 95% CI: 0.60-1.18); and the response rate was 12.9% (S-1) and 14.0% (DTX). The adjusted mean QOL score difference (S-1-DTX until wk 48) was 7.41 (95% CI: 0.37-14.46). Safety profiles were generally consistent with those of the overall EAST-LC population. CONCLUSIONS: S-1 revealed comparable efficacy, safety, and QOL versus DTX in pretreated elderly patients with advanced NSCLC. Results were consistent with the overall EAST-LC data.

Ramucirumab Plus Erlotinib Versus Placebo Plus Erlotinib in Patients With Untreated Metastatic EGFR-Mutated NSCLC: RELAY Japanese Subset.

INTRODUCTION: The phase 3 RELAY global study (NCT02411448) revealed significant improvement in progression-free survival (PFS) with ramucirumab plus erlotinib (RAM + ERL) compared with placebo plus ERL (PL + ERL) in untreated EGFR-mutated metastatic NSCLC (hazard ratio [HR] = 0.59 [95% confidence interval (CI): 0.46-0.76, p < 0.0001]). This prespecified analysis evaluates efficacy, safety, and postprogression EGFR T790M rates of RELAY patients enrolled in Japan. METHODS: Patients were randomized (1:1) to oral ERL (150 mg/d) plus intravenous RAM (10 mg/kg) or PL every 2 weeks. End points included PFS (primary), safety (secondary), and biomarker analyses (exploratory). Plasma samples collected at baseline and poststudy treatment discontinuation were evaluated for EGFR T790M mutations by next-generation sequencing. RESULTS: The Japanese subset included 211 of 449 (47.0%) RELAY patients (RAM + ERL, n = 106; PL + ERL, n = 105). Median PFS was 19.4 versus 11.2 months for RAM + ERL versus PL + ERL treatment (HR = 0.610 [0.431-0.864]) in the Japanese intent-to-treat population, 16.6 versus 12.5 months (HR = 0.701 [0.424-1.159]) in the EGFR exon 19 deletion subgroup, and 19.4 versus 10.9 months (HR = 0.514 [0.317-0.835]) in the EGFR exon 21 L858R subgroup, respectively. Adverse events of grade 3 or above with RAM + ERL included hypertension (24.8%, all grade 3) and dermatitis acneiform (23.8%). Postprogression treatment-emergent T790M rates were similar between arms (RAM + ERL: 47%, 9 of 19 patients; PL + ERL: 50%, 20 of 40 patients). CONCLUSIONS: Clinically meaningful efficacy was observed with RAM + ERL versus PL + ERL in the RELAY Japanese subset, with no new safety concerns. Postprogression T790M rates were similar across treatment arms, indicating the addition of RAM did not affect the ERL-associated EGFR T790M rates at disease progression.

Identification of patients with COVID-19 who are optimal for methylprednisolone pulse therapy.

BACKGROUND: Corticosteroids have been reported to reduce the mortality rates in patients with coronavirus disease 2019 (COVID-19). Additionally, the role of high-dose methylprednisolone pulse therapy in reducing mortality in critically ill patients has also been documented. The purpose of this study is to identify patients with COVID-19 who are suitable for methylprednisolone pulse therapy. METHODS: This was a retrospective study that included patients with COVID-19 receiving methylprednisolone pulse therapy (≥250 mg/day for 3 days) with subsequent tapering doses at our hospital between June 2020 and January 2021. We examined the differences in background clinical factors between the surviving group and the deceased group. RESULTS: Out of 156 patients who received steroid therapy, 17 received methylprednisolone pulse therapy. Ten patients recovered (surviving group) and seven patients died (deceased group). The median age of the surviving and deceased groups was 64.5 years (range, 57-85) and 79 years (73-90), respectively, with a significant difference (p=0.004). Five of the deceased patients (71%) had developed serious complications associated with the cause of death, including pneumothorax, pneumomediastinum, COVID-19-associated pulmonary aspergillosis, cytomegalovirus infection, and bacteremia. On the other hand, out of the 10 survivors, only one elderly person had cytomegalovirus infection and the rest recovered without complications. CONCLUSION: Administration of methylprednisolone pulse therapy with subsequent tapering may be an effective treatment in patients with COVID-19 up to the age of early 70s; however, severe complications may be seen in elderly patients.

Reproducibility of peripheral branches in virtual bronchoscopic navigation using VINCENT and LungPoint software for peripheral lung lesions.

BACKGROUND: Recently, virtual bronchoscopic navigation (VBN) has become frequently used for the pathological specimen collection of peripheral lung lesions using various VBN software packages. Herein, we examined the reproducibility of peripheral branches in VBN software using LungPoint and VINCENT versions 4.0 and 5.5. METHODS: This study included patients suspected of malignant peripheral lung lesions who underwent bronchoscopy at our hospital from February 2016 to April 2017. Computed tomography was taken at a thickness of 1.25 mm in all cases, and VB images were created based on the computed tomography data using LungPoint, or VINCENT version 4.0 or 5.5. One observer read the program-generated VB images and compared how many branches could be visualized with the lobe bronchus as the primary branch. RESULTS: A total of 129 patients (n = 131 lesions) underwent bronchoscopy, with 82 cases of primary lung cancer. Pathological bronchoscopic diagnosis was done in 63 cases, resulting to a diagnostic rate of 76.8%. VB images generated by LungPoint, and VINCENT versions 4.0 and 5.5 reproduced an average of 4.3, 3.47, and 5.12 branches, respectively, with significant differences (p < 0.05) between them. CONCLUSIONS: VINCENT version 5.5 exhibits better reproducibility of peripheral branches than LungPoint for VBN.

Disseminated nocardiosis due to Nocardia terpenica.

We report the first case of disseminated nocardiosis due to trimethoprim/sulfamethoxazole-resistant Nocardia terpenica successfully treated with meropenem and clarithromycin. The patient travelled to Japan from Australia via Southeast Asia, which led to differential diagnoses of multiple lung nodules including miliary tuberculosis and melioidosis as well as nocardiosis. Because of variety of susceptibility depending on the Nocardia species, clinicians need to confirm the species and investigate its susceptibility.

Prognostic impact of geriatric assessment in elderly patients with non-small cell lung cancer: an integrated analysis of two randomized phase III trials (JCOG1115-A).

OBJECTIVE: Patients' actual age and performance status do not always accurately identify the 'fit elderly' for chemotherapy. This study aimed to determine whether four geriatric assessment tools could predict prognosis. METHODS: This study were analyzed using the data of two randomized phase III trials (JCOG0207 and JCOG0803/WJOG4307L) for elderly patients with advanced non-small cell lung cancer and included all eligible patients who were assessed before treatment with four geriatric assessment tools: the Barthel activities of daily living index, Lawton instrumental activities of daily living scale, Mini-Mental State Examination, and Geriatric Depression Scale-15. Univariable and multivariable analyses for overall survival, adjusted for baseline factors, were performed using a stratified Cox regression model with treatment regimen as strata. RESULTS: This analysis included 330 patients aged 70-74, 75-79 or 80 or more (n = 95/181/54), with a performance status of 0 or 1 (n = 119/211). Patients were divided into three groups based on Mini-Mental State Examination and two groups based on Geriatric Depression Scale, but over 80% of patients had perfect scores for both activities of daily living and instrumental activities of daily living. In overall survival subgroup analyses by GA tool, only Mini-Mental State Examination scores were associated with substantial outcome differences (median survival times: 21.2, 13.5 and 12.2 months for scores 30, 29-24 and ≤23). After adjusting for baseline factors, the Mini-Mental State Examination, sex and performance status were tended to be worse overall survival. CONCLUSION: MMSE scores, performance status and sex, but not chronological age, effectively predicted the prognosis of elderly patients. Further studies should confirm that the Mini-Mental State Examination is useful for determining the indication of chemotherapy in elderly patients with advanced non-small cell lung cancer.

Five-year follow-up results from phase II studies of nivolumab in Japanese patients with previously treated advanced non-small cell lung cancer: pooled analysis of the ONO-4538-05 and ONO-4538-06 studies.

BACKGROUND: Two phase II studies in Japan examined the efficacy and safety of nivolumab, a programmed cell death 1 receptor inhibitor, in patients with advanced squamous and non-squamous non-small cell lung cancer (ONO-4538-05 and ONO-4538-06). We examined the long-term efficacy and safety of nivolumab in these patients treated for up to 5 years. METHODS: Patients with squamous (N = 35) or non-squamous (N = 76) non-small cell lung cancer received nivolumab (3 mg/kg every 2 weeks) until disease progression/death. Overall survival and progression-free survival were assessed at 5 years after starting treatment in separate and pooled analyses. Safety was evaluated in terms of treatment-related adverse events. RESULTS: A total of 17 patients were alive at the database lock (26 July 2019). The median overall survival (95% confidence interval) and 5-year survival rate were 16.3 (12.4-25.2) months and 14.3% in squamous patients, 17.1 (13.3-23.0) months and 19.4% in non-squamous patients and 17.1 (14.2-20.6) months and 17.8% in the pooled analysis, respectively. Programmed death ligand-1 expression tended to be greater among 5-year survivors than in non-survivors (P = 0.0703). Overall survival prolonged with increasing programmed death ligand-1 expression, with 5-year survival rates of 11.8, 21.8 and 41.7% in patients with programmed death ligand-1 expression of <1, ≥1-<50 and ≥50%, respectively. Treatment-related adverse events in ≥10% of patients (pooled analysis) included rash (15.3%), malaise (14.4%), decreased appetite (14.4%), pyrexia (14.4%) and nausea (10.8%). CONCLUSIONS: Long-term survival with nivolumab was observed in patients with squamous or non-squamous non-small cell lung cancer. No new safety signals were reported after ≥5 years of follow-up.
