    Abstract Background Compared with standard chemotherapy, epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are more effective in patients with advanced non-small-cell lung cancer (NSCLC) harboring EGFR mutations. However, data comparing the efficacies of different EGFR−TKIs, especially regarding the presence of brain metastasis, are lacking. Methods EGFR-TKI naive patients with recurrent or stage IIIB/IV NSCLC harboring EGFR mutations, excluding resistance mutations, were enrolled in this study. We retrospectively determined progression-free survival (PFS) using the Kaplan−Meier method with log-rank test in patients treated with either gefitinib or erlotinib, cumulative incidence of central nervous system (CNS) progression using the Fine and Gray competing risk regression model, and favorable prognostic factors for CNS progression by multivariate analysis. Results Seventy-seven EGFR-TKI-naive patients were started on either gefitinib (n = 55) or erlotinib (n = 22) in our hospital from April 2010 to April 2016. Among the patients with brain metastasis, PFS tended to be longer in the erlotinib than in the gefitinib group. In the analysis of cumulative incidence, the probability of CNS progression was lower in the erlotinib group than in the gefitinib group. Particularly, in a subgroup analysis of the patients with brain metastasis, there was a significant difference between the erlotinib and gefitinib groups (hazard ratio 0.25; 95% confidence interval, 0.08–0.81; p = 0.021). Of the prognostic factors for CNS progression evaluated, the absence of brain metastasis before EGFR-TKI therapy and receiving erlotinib (vs gefitinib) had a significantly favorable effect on patient prognosis. Conclusion Although this was a retrospective analysis involving a small sample size, erlotinib is potentially more promising than gefitinib for treatment of brain metastasis in patients with EGFR-mutant NSCLC

    This study compared the bioavailability of two pimitespib formulations (Formulations A and B), evaluated the food effect on Formulation A, and evaluated the safety and efficacy of multiple pimitespib doses in patients with solid tumors. This clinical, pharmacological multicenter study had two cohorts and periods. A single dose of Formulation A or B was administered in a crossover design to compare the pharmacokinetics in Cohort 1. In Cohort 2, the effects of fed vs fasting conditions were evaluated among those receiving Formulation A. Subsequently, multiple Formulation A doses were administered to all patients for safety and efficacy assessments. In Cohorts 1 and 2, 12 and 16 patients, respectively, were analyzed for pharmacokinetics. Thirty patients were analyzed for safety and efficacy. Maximum concentration (C-max), area under the curve (AUC)(last), and AUC(inf) geometric mean ratios for Formulations A and B (90% confidence interval [CI]) were 0.8078 (0.6569-0.9933), 0.7973 (0.6672-0.9529), and 0.8094 (0.6697-0.9782), respectively; 90% CIs were not within the bioequivalence range (0.80-1.25). In Cohort 2, mean C-max, AUC(last), and AUC(inf) were higher in fed vs fasting conditions. No safety concerns emerged with single or multiple administration. Overall response rate, disease control rate, and median progression-free survival were 0%, 33%, and 1.5 months, respectively. Four patients had stable disease >= 5 months. Bioequivalence of the two formulations was unconfirmed. Systemic exposure of Formulation A was approximately 20% less than Formulation B. A high-fat/calorie meal increased the relative pharmacokinetics and bioavailability of a single 160-mg dose.

    The G8 questionnaire is a quick and easy-to-use screening tool. Several studies reported that the G8 questionnaire had a high sensitivity for predicting abnormalities in the full comprehensive geriatric assessment and predicted functional decline and survival in elderly cancer patients. The present study aimed to evaluate the role of the G8 questionnaire for predicting clinical outcomes and overall survival (OS) in elderly patients with lung cancer, who received chemotherapy or chemoradiotherapy. The data of 101 lung cancer patients aged ≥70 years, who were hospitalized between September 2011 and August 2014, were analyzed. Of these patients (median age, 77 years), 83 (82%) had impaired G8 scores. The proportion of patients with an impaired G8 score was significantly higher in patients aged ≥80 years than those aged <80 years (p = 0.04). All 18 patients with a normal G8 score possessed an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0 or 1, and none of the patients with a normal G8 score had an ECOG PS of ≥2 (p < 0.0001). An impaired G8 score tended to correlate with a relative dose intensity of <0.65 in patients who received chemotherapy or chemoradiotherapy (p = 0.05, odds ratio = 5.40). In the univariate analysis, an ECOG PS of ≥2 and an impaired G8 score were significantly associated with a poor OS (p = 0.009 and p = 0.003, respectively). Moreover, in the multivariate analysis, an ECOG PS of ≥2 (HR 2.55; 95% CI, 1.23-5.30; p = 0.01) and an impaired G8 score (HR 3.86; 95% CI, 1.44-13.36; p = 0.006) were remained independent prognostic factor for OS. G8 screening tool is useful for the prognostication of elderly lung cancer patients treated with chemotherapy. These finding suggest that the G8 questionnaire could be a useful tool in treatment decision-making to predict prognosis and prevent patients from receiving inappropriate anti-cancer treatment near the end of life

    Abstract Background The relationship between epidermal growth factor receptor tyrosine kinase inhibitor (EGFR‐TKI) resistance, including osimertinib, and programmed cell death‐ligand 1 (PD‐L1) expression status in EGFR‐mutated non‐small cell lung carcinoma (NSCLC) remains unclear. Patients and Methods We retrospectively analyzed 64 patients with unresectable advanced or metastatic NSCLC carrying EGFR exon 19 deletions (ex19del) or EGFR exon 21 L858R substitutions (L858R) who received osimertinib as the first‐line treatment. We compared progression‐free survival (PFS) between eligible patients with PD‐L1 tumor proportion scores (TPS) ≥20% and PD‐L1 TPS <20% using the Kaplan–Meier survival plots with a log‐rank test. Multivariate analysis was performed to examine the poor prognostic factors of PFS. Results The PD‐L1 TPS ≥20% group included 22 cases (median [range] age: 70.5 [33–86] years; 10 women [45.5%]; 11 current or ex‐smokers [50%]); ECOG performance status (PS) of 0–1/2/3/4 was noted in 16/4/1/1 patients, respectively. The PD‐L1 TPS <20% group included 42 patients (median [range] age 73 [43–88] years; 29 women [69%]; 12 current or ex‐smokers [28.6%]); ECOG PS of 0–1/2/3/4 was noted in 33/6/3/0 cases, respectively. The median PFS was 9.1 and 28.1 months in the PD‐L1 TPS ≥20% and PD‐L1 TPS <20% groups, respectively (log‐rank p = 0.013). Multivariate analysis revealed that PD‐L1 TPS ≥20% was associated with PFS (hazard ratio: 2.35, 95% confidence interval: 1.09–5.08, p = 0.030). Conclusion PD‐L1 TPS ≥20% in patients with EGFR‐mutated NSCLC may be associated with early resistance to osimertinib

    Purpose:The purpose of this study was to determine the effect of intervention by certified nurse specialist in psychiatric mental health nursing(PMHCNS)on depressive cancer patients.Method:The randomized controlled trial design was used.Inpatients from three hospitals were randomly allocated into the intervention(n=34)or control group(n=37). Participants in the former group received PMHCNS intervention while control participants were given a booklet about self-management of depressive symptoms.The primary outcome was scores of depression evaluated on the patient Health Questionnaire(PHQ)-9 scale before and after intervention. Results:PHQ-9 scores improved in both groups.As a result of 2-way ANOVA,there were significant interaction effects between the intervention and time in the scores.Conclusion:The result of the study provided evidence to support that PMHCNS intervention improves depression.目的:がん患者の抑うつ状態を改善するためのケア・パッケージを用いた精神看護専門看護師による介入の効果を検討する.方法:造血器腫瘍あるいは肺がんの診断を受け,化学療法目的で入院した患者を対象とした.うつ尺度(PHQ-9)によるスクリーニングで軽度から中等度の抑うつ状態にある対象者を介入群(n=34)と対照群(n=37)の2群に無作為に割り付けた.介入群には1回30分以上,週2回,合計4回の個別面接を実施し,対照群には心理教育パンフレットを手渡して,介入/観察前後の2時点で無作為化比較試験による評価を行った.結果:二元配置分散分析の結果,両群とも有意にPHQ-9得点が改善した.加えて介入と時間の交互作用が認められ,介入群の改善度が大きいことが示された.結論:ケア・パッケージを用いた精神看護専門看護師による介入は,がん患者の抑うつ状態の改善度を高めると考えられた
