A case of spinal cord infarction presenting with unilateral C5 palsy.

A 75-year-old man developed sudden-onset tetraparesis preceded by chest pain. MRI of the cervical spine on the day of onset showed no abnormalities. Although his motor symptoms improved gradually, the weakness of the muscles innervated by the C5 nerve root persisted. Sensory and autonomic deficits were detected on an additional neurological examination, and follow-up MRI eight days after onset revealed spinal cord infarction at the right anterior horn at C3-C4. This case suggests that motor symptoms mimicking a radiculopathy could be present during the course of spinal cord infarction.

A Phase â ¡ Study of Ubenimex Combined With Pembrolizumab, Nab-Paclitaxel, and Carboplatin for Previously Untreated Advanced Squamous Non-Small-Cell Lung Cancer: TORG2241 (UBE-Q).

BACKGROUND: According to the results of the KEYNOTE-407 trial, pembrolizumab plus platinum-based chemotherapy is the standard of care for patients with previously untreated advanced squamous non-small-cell lung cancer (NSCLC). Ubenimex, a potent aminopeptidase inhibitor, is an oral drug with immunostimulatory and antitumor activities. We aim to assess the safety and efficacy of ubenimex in combination with pembrolizumab, nab-paclitaxel, and carboplatin in patients with previously untreated advanced squamous NSCLC. PATIENTS AND METHODS: This prospective, single-arm, multicenter, phase II clinical trial is conducted to confirm the tolerability and efficacy of the tested drugs. Patients with previously untreated advanced squamous NSCLC will receive a predetermined daily dose of ubenimex orally plus 4 cycles of pembrolizumab, nab-paclitaxel, and carboplatin, followed by continuous administration of ubenimex and pembrolizumab for a maximum of 2 years. To confirm tolerability, the daily dose of ubenimex will begin at level 1 (30 mg), which will be increased to levels 2 (60 mg) and 3 (120 mg) according to the escalation criteria, with a standard 3 + 3 design for achieving the target dose-limiting toxicity rate of 33%. The efficacy, safety, and tolerability of ubenimex at the determined dose level will be analyzed. The primary endpoint of the efficacy evaluation will be the objective response rate assessed by an independent review committee. CONCLUSIONS: This is the first study to evaluate the efficacy and safety of ubenimex combined with pembrolizumab, nab-paclitaxel, and carboplatin in patients with previously untreated advanced squamous NSCLC. The results will help devise future treatment strategies.

Using the neutrophil-to-lymphocyte ratio to predict the outcome of individuals with nonsquamous non-small cell lung cancer receiving pembrolizumab plus platinum and pemetrexed.

BACKGROUND: Factors predicting the response to pembrolizumab plus platinum and pemetrexed combination therapy (Pemb-Plt-PEM) in nonsquamous non-small cell lung cancer (non-sq NSCLC) are unclear. We investigated the Glasgow Prognostic (GP) score, neutrophil-to-lymphocyte ratio (NLR), and body mass index (BMI) as predictors of response to initial treatment with combination therapy in individuals with advanced non-sq NSCLC. METHODS: We retrospectively reviewed 236 patients who received initial treatment with combination therapy for non-sq NSCLC at 13 institutions between December 2018 and December 2020. The usefulness of the GP score, NLR, and BMI as prognostic indicators was assessed. Cox proportional hazard models and the Kaplan-Meier method were used to compare progression-free survival (PFS) and overall survival (OS). RESULTS: The response rate was 51.2% (95% CI: 44.9-57.5%). The median PFS and OS after beginning Pemb-Plt-PEM were 8.8 (95% CI: 7.0-11.9) months and 23.6 (95% CI: 18.7-28.6) months, respectively. The NLR independently predicted the efficacy of Pemb-Plt-PEM-the PFS and OS were more prolonged in individuals with NLR <5 than in those with NLR ≥5 (PFS: 12.8 vs. 5.3 months, p = 0.0002; OS: 29.4 vs. 12.0 months, p < 0.0001). BMI predicted the treatment response-individuals with BMI ≥22.0 kg/m2 had longer OS than did those with BMI < 22.0 kg/m2 (OS: 28.4 vs. 18.4 months, p = 0.0086). CONCLUSIONS: The NLR significantly predicted PFS and OS, whereas BMI predicted OS, in individuals who initially received Pemb-Plt-PEM for non-sq NSCLC. These factors might be prognosis predictors in non-sq NSCLC.

Randomized, Phase II study of pemetrexed plus bevacizumab versus pemetrexed alone after treatment with cisplatin, pemetrexed, and bevacizumab in advanced non-squamous, non-small cell lung cancer: TORG (thoracic oncology research group) 1321.

INTRODUCTION: Cisplatin plus pemetrexed followed by pemetrexed is an efficacious platinum combination regimen for advanced non-squamous, non-small cell lung cancer (NSCLC). Data regarding the addition of bevacizumab, especially in maintenance treatment, are insufficient. METHODS: Eligibility criteria included: no prior chemotherapy; advanced, non-squamous, NSCLC; performance status ≤1; and epidermal growth factor receptor mutation-negative. Patients (N = 108) received induction chemotherapy with cisplatin, pemetrexed, and bevacizumab every 3 weeks for four cycles, and tumor response was needed to confirm four-week response duration. Patients with at least stable disease were randomized to pemetrexed/bevacizumab or pemetrexed alone. The primary endpoint was progression-free survival (PFS) after induction chemotherapy. Myeloid-derived suppressor cell (MDSC) counts of peripheral blood samples were also analyzed. RESULTS: Thirty-five patients each were randomized to the pemetrexed/bevacizumab group and the pemetrexed alone group. PFS was significantly better in the pemetrexed/bevacizumab group than in the pemetrexed alone group (7.0 vs. 5.4 months, hazard ratio: 0.56 [0.34-0.93], log-rank p = 0.023). In patients with partial response to induction therapy, median overall survival was 23.3 months in the pemetrexed alone group and 29.6 months in the pemetrexed/bevacizumab group (log-rank p = 0.077). Pretreatment monocytic (M)-MDSC counts tended to be greater in the pemetrexed/bevacizumab group with poor PFS than in those with good PFS (p = 0.0724). CONCLUSIONS: Addition of bevacizumab to pemetrexed as maintenance therapy prolonged PFS in patients with untreated, advanced, non-squamous NSCLC. Furthermore, an early response to induction therapy and pretreatment M-MDSC counts may be related to the survival benefit of the addition of bevacizumab to the combination of cisplatin and pemetrexed.

Serum leucine-rich α2 glycoprotein as a potential biomarker for systemic inflammation in Parkinson's disease.

There is ample epidemiological and animal-model evidence suggesting that intestinal inflammation is associated with the development of Parkinson's disease (PD). Leucine-rich α2 glycoprotein (LRG) is a serum inflammatory biomarker used to monitor the activity of autoimmune diseases, including inflammatory bowel diseases. In this study, we aimed to investigate whether serum LRG could be used a biomarker of systemic inflammation in PD and to help distinguish disease states. Serum LRG and C-reactive protein (CRP) levels were measured in 66 patients with PD and 31 age-matched controls. We found that serum LRG levels were statistically significantly higher in the PD group than in the control group (PD: 13.9 ± 4.2 ng/mL, control: 12.1 ± 2.7 ng/mL, p = 0.036). LRG levels were also correlated with Charlson comorbidity index (CCI) and CRP levels. LRG levels in the PD group were correlated with Hoehn and Yahr stages (Spearman's r = 0.40, p = 0.008). LRG levels were statistically significantly elevated in PD patients with dementia as compared to those without dementia (p = 0.0078). Multivariate analysis revealed a statistically significant correlation between PD and serum LRG levels after adjusting for serum CRP levels, and CCI (p = 0.019). We conclude that serum LRG levels could be considered a potential biomarker for systemic inflammation in PD.

Phase I/II study of nedaplatin and nab-paclitaxel for patients with previously untreated advanced squamous cell lung cancer: Kanto Respiratory Disease Study Group (KRSG) 1302.

BACKGROUND: Nedaplatin and nab-paclitaxel are each efficacious in the treatment of squamous cell lung cancer. PATIENTS AND METHODS: Eligibility criteria were: no prior chemotherapy, advanced squamous cell lung cancer; performance status 0-1, age > 20 years but < 75 years, and adequate hematologic, hepatic and renal function. Patients received escalating doses of nab-paclitaxel under a fixed dose of nedaplatin (100 mg/m2, day 1) every 3 weeks in phase I. The initial nab-paclitaxel dose was 100 mg/m2 on days 1 and 8 (level 1), and the next dose was 100 mg/m2 on days 1, 8, and 15 (level 2). In phase II, patients received the recommended doses. The primary endpoint was tumor response rate. RESULTS: In phase I, three patients at level 1 experienced no dose-limiting toxicities (DLTs) and two patients at level 2 experienced DLTs. Level 1 was thus determined as the recommended dose. Twenty-three patients were enrolled in phase II. The 3 patients in level 1 and 23 patients in phase II were included together for analyses. Three of these 26 patients were excluded from response analysis due to pneumonia and patient refusal. Response rate was 91.3% (95% confidence interval, 72.0-98.9%). Toxicities observed during all cycles were tolerable. CONCLUSIONS: The recommended dose for this combination was nedaplatin at 100 mg/m2 on day 1 and nab-paclitaxel at 100 mg/m2 on days 1 and 8 every 3 weeks. The combination of nedaplatin and nab-paclitaxel appears safe and efficacious in patients with untreated advanced squamous cell lung cancer.

Clinical Outcomes of Postoperative Adjuvant Chemotherapy for Surgically Resected High-Grade Pulmonary Neuroendocrine Carcinoma.

INTRODUCTION: Data on the clinical outcomes of patients receiving adjuvant chemotherapy for surgically resected high-grade pulmonary neuroendocrine carcinoma (HGNEC) (large-cell neuroendocrine carcinoma and small-cell lung cancer) are limited. This study aimed to evaluate the prognostic significance of adjuvant chemotherapy in patients with HGNEC. METHODS: We retrospectively analyzed patients with surgically resected HGNEC at five institutions in Japan between January 2006 and May 2016. RESULTS: A total of 143 patients were enrolled. Among them, 65 received adjuvant chemotherapy. Four patients who participated in clinical trials were excluded; the remaining 61 patients were included in the study. Fifty-six patients received adjuvant small-cell lung cancer-based chemotherapy. Twenty-five of 29 patients who relapsed after postoperative adjuvant chemotherapy received chemotherapy. The most commonly administered chemotherapy agent was amrubicin. The 3-year relapse-free and overall survival rates were 55.2% and 66.8%, respectively. The median relapse-free and overall survival times for the 25 patients who received chemotherapy after relapse were 12.9 and 27.5 months, respectively. Among them, 22 relapsed within 2 years. Patients who received platinum-doublet chemotherapy after relapse tended to have better time to progression disease and overall survival than those who received single-agent chemotherapy. CONCLUSIONS: Most patients with HGNEC received small-cell lung cancer-based regimens as postoperative adjuvant chemotherapy. Those who relapsed after adjuvant chemotherapy were mainly treated with amrubicin. Our findings suggest that platinum-doublet chemotherapy tends to improve the time to progression disease and overall survival in patients who relapse after postoperative adjuvant chemotherapy.

Association of mitochondrial DNA haplogroup and hearing impairment with aging in Japanese general population of the Iwaki Health Promotion Project.

Age-related hearing loss (ARHL) is a complex multifactorial disorder. Studies in animals, including mitochondria-mutator mice, and in human suggest that oxidative stress and mitochondrial disturbance play an important role in the pathoetiology of ARHL. Mitochondrial DNA (mtDNA) haplogroups are populations with genetically similar traits, and they have been reported to affect the mitochondrial function of oxidative phosphorylation. To gain further insights into the relationships between mitochondrial haplotypes and the susceptibility to cochlear aging, in this study, we aimed to elucidate how the differences in mtDNA haplogroups may affect ARHL development in Japanese general population. We focused on early onset ARHL, as the same mtDNA haplogroup can show either a negative or positive effect on systemic co-morbidities of ARHL that appear later in life. A total of 1167 participants of the Iwaki Health Promotion Project were surveyed in 2014, and 12 major haplotype groups (D4a, D4b, D5, G1, G2, M7a, M7b, A, B4, B5, N9, and F) were selected for the analysis. A total of 698 subjects aged 30 to 65 years were included in the statistical analysis, and the hearing loss group consisted of 112 males (40.3%) and 111 females (26.4%). Multiple logistic regression analysis showed that the male subjects belonging to haplogroup A had a significantly increased risk of hearing loss, whereas the female subjects belonging to haplogroup N9 had a significantly decreased risk of hearing loss. These results suggested that the mtDNA haplogroup may be an indicator for future risk of morbidity associated with ARHL.

Amyotrophic lateral sclerosis: Correlations between fluid biomarkers of NfL, TDP-43, and tau, and clinical characteristics.

OBJECTIVES: We previously reported the diagnostic and prognostic performance of neurofilament light chain (NfL), TAR DNA-binding protein 43 (TDP-43), and total tau (t-tau) in cerebrospinal fluid (CSF) and plasma as amyotrophic lateral sclerosis (ALS) biomarkers. The present study aimed to elucidate associations between clinical characteristics and the markers as well as mutual associations of the markers in ALS patients using the same dataset. METHODS: NfL, TDP-43, and t-tau levels in CSF and plasma in 75 ALS patients were analyzed. The associations between those markers and clinical details were investigated by uni- and multivariate analyses. Correlations between the markers were analyzed univariately. RESULTS: In multivariate analysis of CSF proteins, the disease progression rate (DPR) was positively correlated with NfL (ß: 0.51, p = 0.007) and t-tau (ß: 0.37, p = 0.03). Plasma NfL was correlated with age (ß: 0.53, p = 0.005) and diagnostic grade (ß: -0.42, p = 0.02) in multivariate analysis. Plasma TDP-43 was correlated negatively with split hand index (ß: -0.48, p = 0.04) and positively with % vital capacity (ß: 0.64, p = 0.03) in multivariate analysis. Regarding mutual biomarker analysis, a negative correlation between CSF-NfL and TDP-43 was identified (r: -0.36, p = 0.002). CONCLUSIONS: Elevated NfL and t-tau levels in CSF may be biomarkers to predict rapid DPR from onset to sample collection. The negative relationship between CSF NfL and TDP-43 suggests that elevation of CSF TDP-43 in ALS is not a simple consequence of its release into CSF during neurodegeneration. The negative correlation between plasma TDP-43 and split hand index may support the pathophysiological association between plasma TDP-43 and ALS.

Impaired age-dependent increases in phosphoglycerate kinase activity in red blood cells of Parkinson's disease patients.

BACKGROUND: Impaired bioenergetics are partially involved in the pathogenesis of Parkinson's disease (PD). Phosphoglycerate kinase (PGK), an essential enzyme for glycolysis, has recently attracted attention due to its pathogenic role in PD and as a target for disease-modifying therapies. This study is aimed to evaluate the profiles of PGK activity in red blood cells (RBCs) of PD patients and controls. METHODS: Sixty-eight PD patients and thirty-four age-matched unrelated controls were enrolled. PGK activities of RBCs were measured by the established colorimetric assay and standardized by the same RBC samples. RESULTS: PGK activity of the PD group was significantly higher than that of the control group in participants aged sixty-five years or younger, whereas it was not significantly different between the two groups at any age. PGK activity was positively correlated with aging in the control group, but this was not noted in the PD group. On multivariable analysis by partial correlation in the PD group, PGK activity was negatively correlated with the specific binding ratio of dopamine transporter scintigraphy in the striatum. The levodopa-equivalent daily dose was not significantly correlated with the enzyme activity. CONCLUSION: The results support the following: 1) elevation of PGK activities in RBCs can be detected in relatively young PD patients and with normal aging; 2) the degree of striatonigral degeneration is associated with elevated PGK activities. These are important considerations when the PGK assay is applied as a diagnostic biomarker of PD and to therapeutically monitor PGK-enhancing treatments.

Effectiveness and Safety of EGFR-TKI Rechallenge Treatment in Elderly Patients with Advanced Non-Small-Cell Lung Cancer Harboring Drug-Sensitive EGFR Mutations.

Background and Objectives: Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are effective first-line chemotherapeutic agents for patients with advanced non-small-cell lung cancer (NSCLC) harboring drug-sensitive EGFR mutations. However, the effectiveness of EGFR-TKI rechallenge after first-line EGFR-TKI treatment is not sufficient in elderly patients (over 75 years of age) harboring drug-sensitive EGFR mutations. Therefore, we investigated the effectiveness and safety of EGFR-TKI rechallenge after first-line EGFR-TKI treatment in elderly patients with advanced NSCLC harboring drug-sensitive EGFR mutations. Materials and Methods: Between April 2008 and December 2015, we analyzed 78 elderly patients with advanced NSCLC harboring drug-sensitive EGFR mutations with first-line EGFR-TKI treatment at four Japanese institutions. We retrospectively evaluated the clinical effectiveness and safety profiles of EGFR-TKI rechallenge after first-line EGFR-TKI treatment in elderly patients with advanced NSCLC harboring drug-sensitive EGFR mutations (exon 19 deletion/exon 21 L858R mutation). Results: Twenty-two patients in the cohort were rechallenged with EGFR-TKI. The median age was 79.5 years (range 75-87 years). Despite the fact that it was a retrospective analysis, even with EGFR-TKI rechallenge treatment the response rate was 23%, progression-free survival was 5.3 months, and overall survival was 14.4 months. Common adverse events included rash acneiform, paronychia, diarrhea, and anorexia. There were no treatment-related deaths. Due to the occurrence of adverse events of grade 2 or more, dose reduction was performed in 15 (68.2%) of 22 cases. Conclusions: EGFR-TKI rechallenge treatment after first-line EGFR-TKI treatment in elderly patients with advanced NSCLC harboring drug-sensitive EGFR mutations was one of the limited, safe and effective treatment options for elderly EGFR-positive lung cancer patients.

Pretreatment Glasgow prognostic score predicts survival among patients with high PD-L1 expression administered first-line pembrolizumab monotherapy for non-small cell lung cancer.

BACKGROUND: There are no established biomarkers for predicting the efficacy of first-line pembrolizumab monotherapy in patients with high programmed death-ligand 1 (PD-L1) expression. In this study, we investigated whether the Glasgow prognostic score (GPS), neutrophil-to-lymphocyte ratio (NLR), and body mass index (BMI) can be used to evaluate the effect of first-line pembrolizumab monotherapy in patients with advanced non-small cell lung cancer (NSCLC) who express high levels of PD-L1. METHODS: We reviewed data from 142 patients with high PD-L1 expression who underwent first-line pembrolizumab monotherapy for NSCLC at six Japanese institutions between February 2017 and June 2019 and assessed the prognostic value of the GPS, NLR, and BMI. The Kaplan-Meier method and Cox proportional hazard models were used to examine differences in progression-free survival (PFS) and overall survival (OS). The GPS, NLR, and BMI were calculated using C-reactive protein and albumin concentrations, neutrophil and lymphocyte counts, and body weight and height, respectively. RESULTS: The GPS independently predicted the first-line pembrolizumab monotherapy efficacy, as a good GPS (GPS 0-1) was associated with a significantly better PFS and OS compared to a poor GPS (GPS 2) (PFS: 11.8 vs. 2.9 months, p < 0.0001; OS: not reached vs. 8.3 months, p < 0.0001). Furthermore, BMI independently predicted efficacy, as patients with high BMI (BMI ≥21.4) exhibited significantly better OS compared to those with low BMI (BMI <21.4) (OS: not reached vs. 14.1 months, p = 0.006). CONCLUSIONS: Among patients with high PD-L1 expression undergoing first-line pembrolizumab monotherapy for NSCLC, the GPS is significantly correlated with both PFS and OS, and BMI with OS, indicating that they could be used to predict treatment outcome in these patients. To the best of our knowledge, this is the first study to assess the relationship among the GPS, NLR, and BMI and survival among patients with high PD-L1 expression undergoing first-line pembrolizumab monotherapy for NSCLC.

Post-Progression Survival Influences Overall Survival among Patients with Advanced Non-Small Cell Lung Cancer Undergoing First-Line Pembrolizumab Monotherapy.

BACKGROUND: Among patients with non-small cell lung cancer (NSCLC), the impact of first-line treatment on overall survival (OS) may be influenced by subsequent therapies. Thus, using patient-level data, we assessed the relationships of progression-free survival (PFS) and post-progression survival (PPS) with OS among patients with high-programmed death-ligand 1 (PD-L1) expression undergoing first-line pembrolizumab monotherapy for NSCLC. METHODS: We reviewed data from 133 patients with high PD-L1 expression undergoing first-line pembrolizumab monotherapy for NSCLC at 6 Japanese centers between February 2017 and December 2018. The correlations of PFS and PPS with OS were evaluated at the patient level. RESULTS: Linear regression analyses and Spearman's rank correlation coefficient revealed that PPS was strongly correlated with OS (r = 0.76, p < 0.05, R2 = 0.65), while PFS was only moderately correlated with OS (r = 0.71, p < 0.05, and R2 = 0.4). Furthermore, PPS was significantly associated with performance status at the end of pembrolizumab monotherapy, as well as the use of platinum-based combination chemotherapy after pembrolizumab monotherapy (both p < 0.05). CONCLUSIONS: Among patients with high PD-L1 expression undergoing first-line pembrolizumab monotherapy for NSCLC, PPS was more strongly correlated with OS, relative to the relationship between PFS and OS. Therefore, subsequent treatment appears to significantly influence OS in patients with disease progression following first-line pembrolizumab monotherapy.

An autopsy case of corticobasal syndrome due to asymmetric degeneration of the motor cortex and substantia nigra with TDP-43 proteinopathy, associated with Alzheimer's disease pathology.

We herein report a case of corticobasal syndrome (CBS) due to asymmetric degeneration of the motor cortex and substantia nigra with transactivation response DNA-binding protein of 43 kDa (TDP-43) proteinopathy, associated with Alzheimer's disease (AD) pathology. An 85-year-old man initially noticed that he had difficulty in walking and had trouble in moving his right hand and lower limb one year later. His gait disturbance was aggravated, and at the age of 87 years, his neurological examination revealed parkinsonism and positive frontal lobe signs. Brain magnetic resonance imaging (MRI) revealed atrophy of the left frontotemporal lobe and cerebral peduncle, and cerebral blood flow scintigraphy revealed hypoperfusion of the left frontotemporal lobe, leading to a possible diagnosis of CBS. At the age of 89 years, he was bedridden, and rarely spoke. He died of aspiration pneumonia five years after the onset of initial symptoms. At the autopsy, the brain weighed 1280 g and showed left-sided hemiatrophy of the cerebrum and cerebral peduncle. Neuropathological examination revealed AD pathology (Braak AT8 stage V, Braak stage C, CERAD B, Thal classification 5). Phosphorylated TDP-43 (p-TDP-43) immunohistochemistry revealed widespread deposits of dystrophic neurites (DNs), glial cytoplasmic inclusions (GCIs), and neuronal cytoplasmic inclusions (NCIs), which were most remarkable in layers II/III of the motor cortex and predominant on the left hemisphere of the frontal cortex, these neuropathology being consistent with frontotemporal lobar degeneration with TDP-43 (FTLD-TDP) type A. Interestingly, neuronal loss in the substantia nigra was more severe on the left than the right side, with a few phosphorylated tau (p-tau) and p-TDP-43 deposits. It is highly likely that asymmetric TDP-43 pathology rather than symmetric tau pathology contributed to the laterality of degeneration of the cerebral cortex, substantia nigra, and pyramidal tract, which led us to suggest that TDP-43 proteinopathy might be a primary cause.

Risk factors for neuropsychiatric symptoms in patients with Parkinson's disease during COVID-19 pandemic in Japan.

The worsening of neuropsychiatric symptoms such as depression, anxiety, and insomnia in patients with Parkinson's disease (PD) has been a concern during the COVID-19 pandemic, because most people worked in self-isolation for fear of infection. We aimed to clarify the impact of social restrictions imposed due to the COVID-19 pandemic on neuropsychiatric symptoms in PD patients and to identify risk factors associated with these symptoms. A cross-sectional, hospital-based survey was conducted from April 22, 2020 to May 15, 2020. PD patients and their family members were asked to complete paper-based questionnaires about neuropsychiatric symptoms by mail. PD patients were evaluated for motor symptoms using MDS-UPDRS part 2 by telephone interview. A total of 71 responders (39 PD patients and 32 controls) completed the study. Although there was no difference in the age distribution, the rate of females was significantly lower in PD patients (35%) than controls (84%) (P < 0.001). Participants with clinical depression (PHQ-9 score ≥ 10) were more common in PD patients (39%) than controls (6%) (P = 0.002). Multivariate logistic regression analysis revealed that an MDS-UPDRS part 2 score was correlated with the presence of clinical depression (PHQ-9 score ≥ 10) and clinical anxiety (GAD-7 score ≥ 7) (clinical depression: OR, 1.31; 95% CI, 1.04-1.66; P = 0.025; clinical anxiety: OR, 1.36; 95% CI, 1.07-1.72; P = 0.013). In the presence of social restrictions, more attention needs to be paid to the neuropsychiatric complications of PD patients, especially those with more severe motor symptoms.

Randomized phase II trial of S-1 plus cisplatin or docetaxel plus cisplatin with concurrent thoracic radiotherapy for inoperable stage III non-small cell lung cancer.

Cisplatin-based chemoradiotherapy is considered standard treatment for unresectable locally advanced non-small-cell lung cancer (LA-NSCLC). This study examined two regimens of chemotherapy in concurrent chemoradiation. Eligible patients with unresectable, radically irradible LA-NSCLC were randomized to either the SP (S-1 and cisplatin) or DP (docetaxel and cisplatin) arms with concurrent thoracic radiotherapy of 60 Gy, comprising 2 Gy per daily fraction. The primary endpoint was the overall survival (OS) rate at 2 years (the 2-year OS rate). From May 2011 to August 2014, 110 patients were enrolled. Of 106 eligible patients, the 2-year OS rates were 79% (95% CI: 66%-88%) and 69% (95% CI: 55%-80%) the SP and DP arms, respectively. The median progression-free survival was 11.6 months for the SP arm and 19.9 months for the DP arm, while the median survival time was 55.2 months for the SP arm and 50.8 months for the DP arm. Grade 3/4 leukopenia were more frequent in DP arm. The incidences of febrile neutropenia and pneumonitis tended to be higher in DP arm. There were no treatment-related deaths in either arm. The primary endpoint was met in both arms. The SP arm as a future reference regimen will be chosen due to fewer toxicities and better OS.

Phase II study of amrubicin plus erlotinib in previously treated, advanced non-small cell lung cancer with wild-type epidermal growth factor receptor (TORG1320).

Background Amrubicin (AMR) is a completely synthetic 9-aminoanthracycline and clinically active against non-small cell lung cancer (NSCLC). We conducted a phase I study of AMR and erlotinib (ERL) combination therapy in previously treated patients with advanced NSCLC and have already reported the safety and effectiveness. Methods We conducted a multi-center, single-arm phase II trial to evaluate the efficacy of AMR and ERL combination therapy in patients with previously treated, advanced NSCLC harboring wild-type EGFR, PS 0-1 and < 75 years of age. Patients were treated at 3-week intervals with AMR plus ERL. The primary endpoint was the PFS, and the secondary endpoints were the response rate (RR), disease control rate (DCR), overall survival (OS) and toxicity. The trough ERL concentration (Ctrough) was measured as an exploratory study to analyze the relationship between the efficacy/safety and pharmacokinetics. Results From June 2013 to July 2016, 25 patients were enrolled in this trial. The PFS according to the central test was 3.6 months (95% confidence interval 2.1-5.1). The RR and DCR were 24.0% and 64.0%, respectively. We had no treatment-related deaths in this study. Conclusions The PFS of AMR and ERL combination therapy was superior to that of AMR monotherapy in the historical setting, but the primary endpoint was not met in this trial. In our study, the pharmacokinetic analysis showed that the Ctrough of ERL was elevated with combination therapy. This combination therapy might be a viable treatment for previously treated NSCLC patients without a driver oncogene mutation. Clinical trial information UMIN 000010582.
