RESUMO

INTRODUCTION: Cisplatin-based chemotherapy was established in the 1980s, and it has been improved by the development of a short hydration protocol in lung cancer therapy. However, cisplatin-based chemotherapy is still associated with renal toxicity. Because 5-aminolevulinic acid (5-ALA) with sodium ferrous citrate (SFC) is known to be a mitochondrial activator and a heme oxygenase-1 (HO-1) inducer, 5-ALA with SFC is speculated to mitigate cisplatin-induced renal inflammation. METHODS: We investigated the effects of oral administration of 5-ALA with SFC for preventing cisplatin-based nephrotoxicity in patients with lung cancer and evaluated its benefits for patients who received cisplatin-based chemotherapy. The primary endpoint was the significance of the difference between the serum creatinine (sCr) levels of the patients administered 5-ALA with SFC and those given placebo after course 1 of chemotherapy. The difference in the estimated glomerular filtration rate (eGFR) between the two groups was also evaluated as the secondary endpoint. RESULTS: The double-blind, randomized two-arm studies were conducted at 15 medical facilities in Japan; 54 male and 20 female patients with lung cancer who received cisplatin-based chemotherapy between the ages of 42 and 75 years were included in the study. The compliance rate was greater than 94% in the primary assessment and subsequent drug administration periods. All enrolled patients completed the four cycles of cisplatin-based chemotherapy with short hydration. The average level of sCr on day 22 of course 1 was 0.707 mg/dL in the group treated with 5-ALA and SFC and 0.735 mg/dL in the placebo group, respectively, and the sCr in the test group was significantly lower than that in the placebo group (p = 0.038). In addition, the eGFR was significantly higher in the SPP-003 group than in the placebo group up to day 1 of course 3 (84.66 and 75.68 mL/min/1.73 m2, respectively, p = 0.02) and kept better even after the last administration of the study drug (82.37 and 73.49 mL/min/1.73 m2, respectively, p = 0.013). CONCLUSIONS: The oral administration of 5-ALA with SFC is beneficial to patients undergoing cisplatin-based chemotherapy for lung cancer with short hydration.

RESUMO

Background: This multicenter, open-label, single-arm phase II study [Niigata Lung Cancer Treatment Group (NLCTG) 1302] was conducted to evaluate the efficacy and safety of nanoparticle albumin-bound paclitaxel (nab-paclitaxel) monotherapy for previously treated patients with advanced non-small cell lung cancer (NSCLC). We also investigated chemotherapy-induced peripheral neuropathy (CIPN) to evaluate the quality of life (QOL). Methods: Sixty-five patients with advanced NSCLC from 14 participating institutions who had previously undergone one or two cytotoxic chemotherapy regimens were enrolled in this study. The patients received 100 mg/m2 nab-paclitaxel intravenously on days 1, 8, and 15, every 4 weeks. The primary endpoint was overall objective response rate. CIPN symptoms were prospectively assessed using the Patient Neurotoxicity Questionnaire (PNQ) and Common Terminology Criteria for Adverse Events (CTCAE). Results: The overall response rate (ORR) was 18.5% [95% confidence interval (CI): 10.9-29.6%], and the median progression-free survival (PFS) was 3.4 (95% CI: 2.5-4.3) months. Median overall survival (OS) was 8.6 (95% CI: 7.1-10.2) months. The most common non-hematologic grade ≥3 adverse events were infection (7.7%) and hyponatremia (4.6%). Neutropenia was the most common grade 3 or 4 adverse event (30.8%), and febrile neutropenia developed in 6.2% patients. The PNQ and CTCAE scores for motor peripheral neuropathy were low (kappa =0.10). Conclusions: The primary endpoint was achieved. Nab-paclitaxel was well tolerated and showed anti-tumor activity in patients with previously treated NSCLC. This study demonstrates a low degree of concordance in CIPN grading between physicians and patients. Trial Registration: University hospital Medical Information Network Clinical Trial Registry (ID: UMIN000012343).

RESUMO

OBJECTIVES: Although immune checkpoint inhibitors (ICIs) have been shown to improve overall survival (OS) in advanced non-small-cell lung cancer (NSCLC) patients, ICIs sometimes cause various types of immune-related adverse events (irAEs), which lead to the interruption of ICI treatment. This study aims to evaluate the clinical significance of the continuation of ICIs in NSCLC patients with irAEs and to assess the safety and efficacy of the readministration of ICIs after their discontinuation due to irAEs. METHODS: We retrospectively identified patients with advanced NSCLC who were treated with first- to third-line anti-programmed cell death-1 (PD-1) therapy from January 2016 through October 2017 at multiple institutions belonging to the Niigata Lung Cancer Treatment Group. Progression-free survival (PFS) and OS from the initiation of ICI treatment were analyzed in patients with and without irAEs, with and without ICI interruption, and with and without ICI readministration. A 6-week landmark analysis of PFS and OS was performed to minimize the lead-time bias associated with time-dependent factors. RESULTS: Of 231 patients who received anti-PD-1 antibodies, 93 patients (40%) developed irAEs. Of 84 eligible patients with irAEs, 32 patients (14%) continued ICIs, and OS was significantly longer in patients who continued ICIs than that in patients who discontinued ICIs [not reached (95% CI: NE-NE) vs. not reached (95% CI: 22.4-NE); p = 0.025]. Of 52 patients who discontinued ICIs, 14 patients (6.1%) readministered ICIs, and OS in patients with ICI readministration was significantly longer than that in patients without ICI readministration [not reached (95% CI: NE-NE) vs. not reached (95% CI: 8.4-NE); p = 0.031]. CONCLUSION: The current study demonstrated that both the continuation and readministration of ICIs after irAE occurrence improved OS compared to the permanent interruption of ICIs in NSCLC patients with ICI-related irAEs.

RESUMO

BACKGROUND: Although immune checkpoint inhibitors (ICIs) are effective for advanced non-small cell lung cancer (NSCLC), ICIs may cause interstitial lung disease (ILD), which results in treatment discontinuation and is sometimes fatal. Despite the high incidence of ICI-related ILD, there are few cancer treatment options for patients. This study aimed to evaluate the safety and efficacy of subsequent systemic cancer therapy in NSCLC patients with ICI-related ILD. METHODS: We retrospectively assessed NSCLC patients who received programmed cell death-1 (PD-1) inhibitors as first- to third-line therapy at participating institutions of the Niigata Lung Cancer Treatment Group from January 2016 to October 2017. RESULTS: This analysis included 231 patients, 32 (14%) of whom developed ICI-related ILD. Of these patients, 16 (7%) received subsequent systemic cancer treatments. The median overall survival (OS) tended to be longer in the systemic cancer therapy group than in the no systemic cancer therapy group [22.2 months (95% CI: 1-NE) vs. 4.5 months (95% CI: 1-NE); P=0.067]. ICI-related ILD recurred in half of the patients who received systemic cancer therapy, and the median OS tended to be shorter in patients with recurrent ICI-related ILD [22.0 months (95% CI: 1-NE) vs. 7.0 months (95% CI: 1-NE); P=0.3154]. CONCLUSIONS: According to the current study, systemic cancer treatment is effective in patients with ICI-related ILD; however, its safety is uncertain because of the high risk of ICI-related ILD recurrence and poor survival outcome following ILD recurrence.

RESUMO

A 70-year-old man, treated for asthma for 2 years and chronic sinusitis for several months, presented with fever, numbness in the lower limbs, heaviness in the head, gross hematuria, and black stools. He also had eosinophilia, elevated serum IgG4 levels, high levels of myeloperoxidase-anti-neutrophil cytoplasmic antibodies (MPO-ANCA), and pulmonary infiltrative shadows. Bronchoscopy revealed multiple white flattened lesions (white moss) on the airway mucosa, suggesting mycobacterial infection or malignancy. A biopsy from tracheal mucosa revealed airway inflammation with marked eosinophil infiltration. The patient was diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA) and treated with steroids, and all findings improved. However, a year and a half after the initiation of treatment, eosinophils and IgE gradually increased; subjective symptoms, such as asthma symptoms and numbness in the lower limbs, worsened; and ANCA, which had been negative, turned positive. Therefore, we suspected disease relapse and anti-IL-5 antibody (mepolizumab) treatment was initiated. Thereafter, ANCA turned negative again, eosinophils and IgE normalized, and subjective symptoms decreased. The presence of airway mucosal lesions in EGPA is relatively rare, and we report this case as a valuable case owing to the interesting bronchoscopic findings that are worth comprehending as a respiratory physician.

RESUMO

BACKGROUND: Afatinib has shown clinical benefits in patients with non-small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) mutations. Many patients treated with afatinib experience skin or gastrointestinal toxicity. However, an effective management strategy has not been established. This prospective study was conducted to evaluate the efficacy of multimodal prophylactic treatment for afatinib-induced toxicity. METHODS: This single-arm prospective study was conducted to evaluate the efficacy of multimodal prophylactic treatment for afatinib-induced toxicity in patients with EGFR mutation positive advanced NSCLC who planned to receive a 40 mg dose of afatinib. Eligible patients were treated with oral loperamide (2 mg twice per day), prophylactic minocycline (100 mg once per day), topical medium-class steroids, and gargling with sodium azulene. The primary endpoint was the ability of prophylactic loperamide to prevent severe or intolerable diarrhea during the 4 weeks after the initial administration of afatinib. The incidence, severity and time to occurrence of diarrhea, rash, oral mucositis and paronychia were evaluated based on a daily patient questionnaire. RESULTS: Forty-six patients were enrolled. The primary endpoint analysis was performed in 35 patients as the per-protocol (PP) population. The 4-week successful prophylaxis rate for severe or intolerable diarrhea was 82.9% (90% confidence interval: 70.1-91.9%). In the total population, the incidences of grade 3 or higher rash, oral mucositis and paronychia within 4 weeks were 4%, 2% and 4%, respectively. CONCLUSIONS: Prophylactic loperamide administration was not effective in preventing severe or intolerable diarrhea during afatinib treatment. Adequate dose reduction will be a better approach to manage afatinib-induced diarrhea. Multimodal prevention using minocycline, topical steroids and gargling with sodium azulene may be helpful to maintain compliance with afatinib treatment (UMIN000016167).

RESUMO

BACKGROUND: Interstitial lung disease (ILD) induced by anti-programmed-cell death-1 (PD-1) and anti-PD-ligand 1 (PD-L1) is potentially life-threatening and is a common reason of the discontinuation of therapy. In contrast, an enhancement in antitumor effects was reported in patients who developed immune-related adverse events, including ILD. Although recent evidence suggests that radiologic patterns of ILD may reflect the severity of ILD and the antitumor immune responses to anti-PD-1/PD-L1 therapies, the association between radiologic features and clinical outcomes remains unclear. METHODS: Patients with advanced non-small-cell lung cancer who were treated with 1st to 3rd line anti-PD-1 therapy from January 2016 through October 2017 were identified at multiple institutions belonging to the Niigata Lung Cancer Treatment Group. ILD was diagnosed by the treating physicians, and chest computed tomography scans were independently reviewed to assess the radiologic features of ILD. RESULTS: A total of 231 patients who received anti-PD-1 therapy were enrolled. Thirty-one patients (14%) developed ILD. Sixteen patients were classified as having ground glass opacities (GGO), 16 were classified as having cryptogenic organizing pneumonia (COP), and one was classified as having pneumonitis not otherwise specified. Patients with GGO had significantly worse overall survival time compared to patients with COP (7.8 months (95% CI: 2.2-NE) versus not reached (95% CI: 13.2-NE); P = 0.0175). Multivariate analysis of all 231 patients also revealed that PS = 1 and ≥2 and GGO were significant predictors of a worse overall survival. CONCLUSIONS: This study demonstrated that patients who developed GGO exhibited worse outcomes among non-small-cell lung cancer patients receiving anti-PD-1 therapies.

RESUMO

BACKGROUND: Although the clinical efficacy of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in EGFR-mutant non-small cell lung cancer (NSCLC) patients has been demonstrated, their efficacy in EGFR-mutant NSCLCs with central nervous system (CNS) metastases and the role of radiotherapy remain unclear. This study aimed to determine if it is preferable to add upfront cranial radiotherapy to EGFR-TKIs in patients with EGFR-mutant NSCLC with newly diagnosed brain metastases. METHODS: We retrospectively analyzed the data of EGFR-mutant NSCLC patients with CNS metastases who received EGFR-TKIs as a first-line therapy. RESULTS: A total of 104 patients were enrolled and 39 patients received upfront brain radiotherapy, while 65 patients received first and second generation EGFR-TKIs first. The median time to treatment failure (TTF) was 7.8 months (95% confidence interval [CI]: 6.3-9.4). The median survival time (MST) was 24.0 months (95% CI: 20.1-30.1). The overall response rate of the CNS was 37%. The median CNS progression-free survival (PFS) was 13.2 months (95% CI: 10.0-16.2). Brain radiotherapy prior to EGFR-TKI prolonged TTF (11.2 vs. 6.8 months, P = 0.038) and tended to prolong CNS-PFS (15.6 vs. 11.1 months, P = 0.096) but was not significantly associated with overall survival (MST 26.1 vs. 24.0 months, P = 0.525). Univariate and multivariate analyses indicated that poor performance status and the presence of extracranial metastases were poor prognostic factors related to overall survival. CONCLUSION: EGFR-TKI showed a favorable effect for EGFR-mutant NSCLC patients with CNS metastases. Prolonged TTF and CNS-PFS were observed with upfront brain radiotherapy.

RESUMO

BACKGROUND: The current randomized, double-blind, phase 2 study assessed the efficacy and safety profile of a single intravenous administration of fosnetupitant, a neurokinin 1 receptor antagonist prodrug, for the prevention of chemotherapy-induced nausea and vomiting in Japanese patients receiving cisplatin-based chemotherapy. METHODS: Patients scheduled to receive cisplatin (at a dose of ≥70 mg/m2 )-based regimens were randomly assigned to receive fosnetupitant at a dose of 81 mg or 235 mg or placebo in combination with palonosetron at a dose of 0.75 mg and dexamethasone. The primary endpoint was complete response (CR; no vomiting and no rescue medication) during the overall phase (0-120 hours). The overall CR rate was compared between each dose of fosnetupitant and the placebo group adjusting for the stratification factors of sex and age class (age <55 years vs age ≥55 years). Safety was assessed, with special attention given to events that potentially were suggestive of infusion site reactions. RESULTS: A total of 594 patients were randomized. Of these, 194 patients, 195 patients, and 195 patients, respectively, in the placebo and fosnetupitant 81-mg and 235-mg dose groups were evaluable for efficacy. The overall CR rate was 54.7% for the placebo group, 63.8% for the fosnetupitant 81-mg dose group (adjusted difference, 9.1%; 95% CI, -0.4% to 18.6% [P = .061]), and 76.8% for the fosnetupitant 235-mg dose group (adjusted difference, 22.0%; 97.5% CI, 11.7% to 32.3% [P < .001]). Safety profiles were comparable between the 3 groups. The incidence of infusion site reactions related to fosnetupitant was ≤1% in each dose group. CONCLUSIONS: Fosnetupitant at a dose of 235 mg provided superior prevention of chemotherapy-induced nausea and vomiting among patients receiving cisplatin-based chemotherapy compared with the control group, and with a satisfactory safety profile.

RESUMO

Background The efficacy and safety of bevacizumab in elderly patients with non-small cell lung cancer remain controversial. This study focused on both selecting fit elderly patients and overcoming interpatient variability with respect to pharmacodynamics. Methods Elderly (age: ≥70 years) patients with advanced non-squamous non-small cell lung cancer were enrolled. Patients with uncontrolled congestive heart failure and uncontrolled diabetes were excluded. The treatment regimen comprised carboplatin at an area under the curve of 5 mg/ml/min on day 1, paclitaxel at 90 mg/m2 on days 1 and 8, and bevacizumab at 15 mg/kg on day 1 every 21 days for up to 4 cycles, followed by maintenance bevacizumab. Dose reduction due to side effects was performed, with a wide range of doses of paclitaxel from 23 mg/m2/week to 60 mg/m2/week. Results Of the 36 patients entered, 38.9% required a dose reduction or cancellation of paclitaxel administration on day 8, and 75% patients were able to complete 4 cycles of triplet therapy. The response rate, primary endpoint, was 69.4% (95% confidence interval [CI]: 51.9-83.7). The median progression free survival and overall survival were 8.4 months and 29.2 months, respectively. The most common adverse events included neutropenia, hypertension, anemia, and infection. Although Grade ≥ 3 adverse events were observed in 24 patients (66.7%), there were no deaths due to toxicity. Conclusion Carboplatin plus weekly paclitaxel with bevacizumab is a feasible, effective first-line regimen for elderly non-small cell lung cancer patients. (UMIN00006622).

RESUMO

BACKGROUND: Chemotherapy-induced nausea and vomiting (CINV) are some of the most problematic symptoms for cancer patients. Triplet therapy consisting of a 5HT3 receptor antagonist, aprepitant, and dexamethasone is a guideline-recommended antiemetic prophylaxis for highly emetogenic chemotherapy (HEC). The efficacy and safety of triplet therapy using a 0.75-mg dose of palonosetron have not yet been investigated. We performed a prospective phase II study using triplet antiemetic therapy with 0.75 mg of palonosetron. METHODS: Chemotherapy-naïve lung cancer patients scheduled to receive HEC were enrolled. The eligible patients were pretreated with antiemetic therapy consisting of the intravenous administration of 0.75 mg of palonosetron, and 9.9 mg of dexamethasone and the oral administration of 125 mg of aprepitant on day 1, followed by the oral administration of 80 mg of aprepitant on days 2-3 and the oral administration of 8 mg of dexamethasone on days 2-4. The primary endpoint was the complete response rate (the CR rate; no vomiting and no rescue medication) during the overall phase (0-120 h). RESULTS: The efficacy analysis was performed in 63 patients. The CR rates during the overall, acute and delayed phases were 81.0, 96.8, and 81.0%, respectively. The no nausea and no significant nausea rate during the overall phase were 54.0 and 66.7%, respectively. The most common adverse event was grade 1 or 2 constipation. CONCLUSIONS: Triplet antiemetic therapy using a 0.75-mg dose of palonosetron shows a promising antiemetic effect in preventing CINV in lung cancer patients receiving HEC.

RESUMO

AIM: To examine the effects of inhaled procaterol (Meptin Air : MA), a short-acting beta2-agonist, for proactive use rather than rescue use in dyspnea and health-related quality of life in patients with chronic obstructive pulmonary disease (COPD), who complained of dyspnea in daily activities despite treatment with long-acting bronchodilators. METHODS: Patients with moderate to most severe COPD who were on maintenance therapy with tiotropium and other long-acting bronchodilators were studied. Severity of dyspnea was evaluated with the Shortness of Breath Questionnaire (SOBQ) and patients were recommended to use MA on an as-needed basis before daily activities which had caused dyspnea. The effects of MA were evaluated with the St. George's Respiratory Questionnaire (SGRQ) and MRC dyspnea scale. Baseline and post-administrative lung functions and exercise capacity (6-minute walking test) were measured. RESULTS: SOBQ revealed that all patients still had dyspnea in daily activities despite maintenance therapy. Inhalation of MA to prevent dyspnea in daily activities on an as-needed basis significantly improved QOL in SGRQ, lung function and MRC scales. Six-minute walking distances showed a tendency to improve. CONCLUSION: Proactive use of MA as needed (assist use) improved QOL and continuing dyspnea despite maintenance drugs. Assist use of MA before effort improved exercise capacity, suggesting that it might improve the ability of activity of daily living (ADL).

RESUMO

Information on obstructive sleep apnea-hypopnea syndrome (OSAHS) in Japan has been limited. The purposes of this clinical study were to evaluate the demographic characteristics of Japanese OSAHS patients and to assess how demographic factors are associated with OSAHS severity. We analyzed 3,659 OSAHS patients who underwent polysomnographic evaluation between January 2000 and December 2004 at 11 hospitals in Niigata Prefecture, Japan. Data consisted of apnea-hypopnea index (AHI) and demographic characteristics, including sex, age, and body-mass index, for statistical analysis. Levels of obesity were classified according to the WHO criteria. The male-to-female patient ratio for OSAHS was 4.6, and male patients presented more severe OSAHS than female patients. High AHI and a high proportion of moderate to serious OSAHS (AHI > or = 15) were found among the patients in their 30s, as well as female patients in their 70s and male patients in their 80s. The AHI and the proportion of moderate-to-serious OSAHS (AHI > or = 15) were greater in patients classified as underweight than in normal weight patients. In conclusion, there is a higher male predominance in the prevalence of OSAHS, and in both sexes, the results suggest different pathophysiological mechanisms of deteriorating OSAHS between adults under age 55 and adults 55 years or over. In addition, underweight patients exhibit more severe OSAHS than normal weight patients.

RESUMO

We measured MICs of various antimicrobial agents against Streptococcus pneumoniae, Haemophilus influenzae, and Pseudomonas aeruginosa isolated in the Nagaoka district of Niigata Prefecture in 2000 (March-May), 2001 (January-May), and 2002 (March-May). S. pneumoniae: Fifty-six strains were isolated in 2000, 119 strains in 2001, and 88 strains in 2002. In 2000, 2001, and 2002, 24 strains (42.9%), 58 strains (48.7%), and 40 strains (45.5%), respectively, were penicillin-intermediate S. pneumoniae (PISP), and 4 strains (7.1%), 12 strains (10.1%), and 7 strains (8.0%), respectively, were penicillin-resistant S. pneumoniae (PRSP). Carbapenems had the most excellent antimicrobial activity, followed by penicillin G, against penicillin-susceptible S. pneumoniae (PSSP), PISP, and PRSP. H. influenzae: Seventy-six strains were isolated in 2000, 154 strains in 2001, and 91 strains in 2002. In 2000, 2001, and 2002, 6 strains (7.9%), 8 strains (5.2%), and 7 strains (7.7%), respectively, were beta-lactamase-producing ampicillin (ABPC)-resistant strains (MIC > or = 2 micrograms/ml), showing no increase, and 14 strains (18.4%), 70 strains (45.5%), and 31 strains (34.1%), respectively, were beta-lactamase-non-producing ABPC-resistant strains (MIC > or = 2 micrograms/ml), showing a slight increase. Ceftriaxon, meropenem (MEPM), and levofloxacin had excellent antimicrobial activity against these resistant strains. P. aeruginosa: In 2000, 2001, and 2002, 135, 74, and 91 strains, respectively, were isolated, and 14 strains (10.4%), 17 strains (23.0%), and 24 strains (26.4%), respectively, were imipenem-resistant (MIC > or = 16 micrograms/ml), showing a slight increase. MEPM, biapenem, and ciprofloxacin had excellent antimicrobial activity against P. aeruginosa.
