RESUMEN

We evaluated a novel transcription-reverse transcription concerted reaction (TRC) assay that can detect influenza A and B within 15 min using nasopharyngeal swab and gargle samples obtained from patients with influenza-like illness, between January and March 2018 and between January and March 2019. Based on the combined RT-PCR and sequencing results, in the nasal swabs, the sensitivity and specificity of TRC for detecting influenza were calculated as 1.000 and 1.000, respectively. In the gargle samples, the sensitivity and specificity of TRC were 0.946 and 1.000, respectively. The TRC assay showed comparable performance to RT-PCR in the detection of influenza viruses.

RESUMEN

Although viruses are the major pathogen that causes upper respiratory tract infection (URTI) and acute bronchitis, antibiotics have been prescribed. This was a prospective observational study in influenza epidemics that enrolled adult outpatients who visited a hospital with respiratory tract infection symptoms. In this study, we evaluated the usefulness of FilmArray respiratory panel (RP). Fifty patients were enrolled. FilmArray RP detected the pathogens in 28 patients. The common pathogens were influenza virus (n = 14), respiratory syncytial virus (n = 6), and human rhinovirus (n = 6). Of the 14 patients with influenza virus, 6 were negative for the antigen test. The physicians diagnosed and treated the patients without the result of FilmArray in this study. Of the patients with positive FilmArray RP, 9 were treated with antibiotics; however, bacteria were detected in only 3 patients. By implementing FilmArray RP, URTI and acute bronchitis would be precisely diagnosed, and inappropriate use of antibiotics can be reduced.

RESUMEN

BACKGROUND: NY-ESO-1 and XAGE1 cancer/testis antigens elicit humoral and cellular immune responses in NSCLC patients. We aimed to predict clinical benefit with ICI monotherapy, using an automated immunoassay of NY-ESO-1/XAGE1 antibodies (Abs). METHODS: This study enrolled 99 NSCLC patients who received nivolumab after chemotherapy, including 21 patients harboring EGFR, ALK, or KRAS alterations. The cutoff value (10 units/mL) of NY-ESO-1 and XAGE1 Ab was determined based on Ab levels in non-malignant controls, and NY-ESO-1/XAGE1 Abs in NSCLC were measured before nivolumab. Differences in PFS and OS between the Ab-positive and Ab-negative groups were retrospectively analyzed using Cox regression analysis after applying inverse probability of treatment weighting (IPTW). RESULTS: NY-ESO-1/XAGE1 Abs were positive in 28 NSCLC, who responded more highly to nivolumab than the Ab-negatives (response rate 50.0% vs. 15.5 %, p < 0.0007). The IPTW-adjusted positives and negatives for NY-ESO-1/XAGE1 Abs were 24.5 and 70.2, respectively. The Ab-positives showed longer IPTW-adjusted PFS (HR = 0.59, 95 % CI: 0.39-0.90, p = 0.014) and IPTW-adjusted OS (HR = 0.51, 95 % CI: 0.32-0.81, p = 0.004) than the Ab-negatives. Among NSCLC harboring driver genes, the Ab-positives (n = 10) showed longer PFS (HR = 0.34, 95 % CI: 0.13-0.89, p = 0.029) and OS (HR = 0.27, 95 % CI: 0.098-0.75, p = 0.012) than the Ab-negatives (n = 11). CONCLUSION: Our immunoassay of NY-ESO-1/XAGE1 Abs is probably useful for predicting the clinical benefit with nivolumab in NSCLC, including those harboring driver genes. These results suggest that our immunoassay may be useful in ICI monotherapy for NSCLC.

RESUMEN

Healthcare-associated pneumonia (HCAP) is a new concept of pneumonia, which was proposed in the ATS/IDSA guidelines. The guidelines explain that HCAP patients should be treated with broad-spectrum antimicrobial drugs directed at multidrug-resistant pathogens. However, in Japan, there are many elderly people who received in-home care service. These patients seemed to be consistent with the concept of HCAP, but they did not meet the definition of HCAP. Therefore, the Japanese Respiratory Society modified the definition of HCAP according to the medical environmental in Japan. We retrospectively observed HCAP patients and nursing home and healthcare-associated pneumonia (NHCAP) patients who were hospitalized during 24 months at the Japanese Red Cross Nagasaki Genbaku Hospital (Nagasaki, Japan). Patient background, disease severity, identified pathogens, initial antibiotic regimens, and outcomes were compared. A total of 108 patients (77 HCAP and 31 NHCAP except HCAP patients) were evaluated. Of NHCAP except HCAP patients, 27 (87.1 %) were above 3 in the ECOG PS score. There were almost no significant differences between the two groups in characteristics, pneumonia severity, identified bacteria, initial antibiotic regimens, and response rate of initial antibiotic therapy. Although the in-hospital mortality of HCAP patients and NHCAP except HCAP patients was 9.1 % and 19.4 %, respectively, this difference did not reach statistical significance (P > 0.05). Our study suggested that, in the criteria of HCAP, some Japanese patients, who were consistent with the concept of HCAP, were classified as community-acquired pneumonia (CAP). Therefore, there is a need to change the definition of HCAP according to the medical environment in Japan.

RESUMEN

BACKGROUND: The aim of this study was to assess the efficacy and safety of amrubicin for previously treated malignant pleural mesothelioma. METHODS: The eligibility criteria were: previously treated unresectable malignant pleural mesothelioma; performance status 0-1; age ≤ 75; adequate hematological, hepatic, and renal function. The patients were injected with 35 mg/m2 amrubicin on days one, two, and three every 3-4 weeks. The planned number of patients was 32. RESULTS: The study was terminated due to delay in enrollment and 10 patients were subsequently enrolled (nine males and one female; median age 67 [range 49-73]), of which four had epithelioid tumors, three had sarcomatoid tumors and three had biphasic tumors, respectively. According to the International Mesothelioma Interest Group (IMIG), one, four, and four patients had stage II, III, and IV, respectively, and one had postoperative recurrence. There was one (10%) partial response, four (40%) had stable disease, and five (50%) patients exhibited disease progression. The overall response and disease control rates were 10% (95% CI: 0.3-44.5%) and 60% (95% CI: 26.2-87.8%), respectively. The median progression-free survival time was 1.6 months. The median overall survival time was 6.6 months, and the one-, two-, and three-year survival rates were 23%, 23%, and 0%, respectively. The observed grade 3 or 4 toxicities included neutropenia in six (60%) patients; leukopenia in five (50%) patients; and febrile neutropenia, thrombocytopenia, anemia, and pneumonia in one (10%) patient each. CONCLUSIONS: There was not enough data to evaluate the efficacy because the study was terminated early. However, amrubicin showed limited activity and acceptable toxicities when used in previously treated malignant pleural mesothelioma patients.

RESUMEN

INTRODUCTION: Anti-vascular endothelial growth factor therapy has been shown to be effective in non-small cell lung cancer (NSCLC) patients with malignant pleural effusion (MPE); however, there are no data to suggest that ramucirumab has the same effects. METHODS: We therefore decided to conduct a phase II study of ramucirumab plus docetaxel for NSCLC patients with MPE. The MPE control rate at eight weeks after the start of treatment will be the primary endpoint, and the objective response rate, progression-free survival, one-year survival rate, overall survival, and toxicity profile will be secondary endpoints. DISCUSSION: A previous study indicated that administering chemotherapy in combination with bevacizumab was effective at controlling pleural effusion in patients with NSCLC with carcinomatous pleurisy. It is expected that ramucirumab will have a similar effect to the same group.

RESUMEN

INTRODUCTION: Programmed cell death-1 (PD-1) inhibitors effectively treat NSCLC and prolong survival. Robust biomarkers for predicting clinical benefits of good response and long survival with anti-PD-1 therapy have yet to be identified; therefore, predictive biomarkers are needed to select patients with benefits. METHODS: We conducted a prospective study to explore whether serum antibody against NY-ESO-1 and/or XAGE1 cancer-testis antigens predicted primarily good clinical response and secondarily long survival with anti-PD-1 therapy for NSCLC. The serum antibody was detected by enzyme-linked immunosorbent assay, and tumor immune microenvironment and mutation burden were analyzed by immunohistochemistry and next-generation sequencing. RESULTS: In the discovery cohort (n = 13), six antibody-positive NSCLC cases responded to anti-PD-1 therapy (two complete and four partial responses), whereas seven antibody-negative NSCLC cases did not. Antibody positivity was associated with good response and survival, regardless of tumor programmed death ligand 1 (PD-L1) expression, mutation burden, and CD8+ T-cell infiltration. In the validation cohort (n = 75), 17 antibody-positive NSCLC cases responded well to anti-PD-1 therapy as compared with 58 negative NSCLC cases (objective response rate 65% versus 19%, p = 0.0006) and showed significantly prolonged progression-free survival and overall survival. Antibody titers highly correlated with tumor reduction rates. In the multivariate analysis, response biomarkers were tumor programmed death ligand 1 expression and antibody positivity, and only antibody positivity was a significantly better predictive biomarker of progression-free survival (hazard ratio = 0.4, p = 0.01) and overall survival (hazard ratio = 0.2, p = 0.004). CONCLUSIONS: Our results suggest that NY-ESO-1 and/or XAGE1 serum antibodies are useful biomarkers for predicting clinical benefits in anti-PD-1 therapy for NSCLC and probably for other cancers.

RESUMEN

BACKGROUND: The first-line treatment for squamous cell lung cancer (SCC) has not necessarily been established; however, our previous exploratory study suggested that the combination of nedaplatin and amrubicin would be a promising treatment approach for patients with SCC. Therefore, a phase II study of this chemotherapeutic combination was designed to evaluate its efficacy and safety for treatment-naïve patients with advanced SCC. METHODS: A total of 21 treatment-naïve patients with stage IIIB/IV or postoperative recurrent SCC were enrolled from six institutions. Nedaplatin (100 mg/m2 ) on day 1 and amrubicin (25 mg/m2 ) on days 1-3 were administered intravenously every 4 weeks. The primary endpoint was overall response rate (ORR), while the secondary endpoints included overall survival (OS), progression-free survival (PFS), and drug toxicities. RESULTS: Partial response was observed in seven of 21 cases (ORR, 33.3%; 95% confidence interval [CI], 14.5-52.2). Disease control rate, which includes stable disease, was 71.4%. Median OS and PFS was 14.6 and 4.1 months, respectively. This regimen did not cause any treatment-related deaths. Grade 3/4 neutropenia developed in 8 of 21 cases (38.1%); however, febrile neutropenia developed in only 9.5% of the cases. Grade 3/4 gastrointestinal or neuromuscular toxicities were not observed. CONCLUSION: The efficacy of the combination of nedaplatin and amrubicin was comparable to that of other conventional chemotherapeutic regimens for treatment-naïve patients with advanced SCC, and no severe gastrointestinal or neuromuscular toxicities were observed. This combination therapy may be an alternative treatment approach, particularly in patients who cannot tolerate gastrointestinal or neuromuscular toxicities.

RESUMEN

INTRODUCTION: Vinorelbine alone and irinotecan alone have been shown to have efficacy against non-small cell lung cancer (NSCLC); each drug has different mechanisms of action. A phase I study using a combination of vinorelbine and irinotecan as first-line treatment for advanced NSCLC was done to determine the maximum tolerated dose (MTD) and the dose-limiting toxicity (DLT). METHODS: Previously untreated patients (or=4 days or febrile neutropenia, grade 4 thrombocytopenia, >or=grade 3 non-hematological toxicities, or the need to cancel drug administration on both days 8 and 15. RESULTS: A total of 23 patients were enrolled. DLT was observed in 1 of 6 patients at level 3 (20 mg/m(2) vinorelbine, 50 mg/m(2 )irinotecan), in 2 of 3 at level 4 (25 mg/m(2), 50 mg/m(2)), and in 2 of 5 at modified level 4 (20, 60 mg/m(2)). Level 4 and modified level 4 were considered to be the MTD; dose level 3 was therefore recommended. DLTs included liver dysfunction, pneumonitis, colitis, and arrhythmia. Injection site reactions were mild. Hematological and non-hematological toxicities were mild and easily controlled. CONCLUSION: Use of 20 mg/m(2) vinorelbine on days 1 and 8 followed by 50 mg/m(2 )irinotecan on days 1, 8, and 15 every 4 weeks warrants a phase II study.

RESUMEN

PURPOSE: The treatment strategy for patients with non-small-cell lung cancer (NSCLC) involving ipsilateral mediastinal lymph nodes is still controversial. We performed a phase II feasibility study of induction chemotherapy followed by surgery for patients with pathologic N2 NSCLC. PATIENTS AND METHODS: Patients with mediastinoscopy- positive stage IIIA N2 NSCLC received 2 cycles of cisplatin 80 mg/m2, vinorelbine 25 mg/m2, and mitomycin-C 8 mg/m2. Patients without progressive disease underwent thoracotomy and lobectomy with lymph node dissections 2-4 weeks later. RESULTS: From January 2000 to July 2004, 24 eligible patients (15 men, 9 women) were enrolled. Induction chemotherapy was completed as planned in 23 patients (95.8%). Hematological toxicity was the primary grade 3/4 toxicity. Twelve (50%) patients achieved a partial response. Twenty-three patients underwent surgical resection, and complete resection was achieved in 22 patients (95.7%). There were no surgery-related deaths. Pathologic complete response in metastatic lymph nodes was achieved in 5 patients. With a median follow-up of 5.4 years (range, 2.88-7.7 years), the estimated 5-year survival was 51.8% (95% CI, 41.3-62.3) and progression-free survival was 46.6% (95% CI, 36-57.2). CONCLUSION: Induction chemotherapy followed by surgery for patients with pathologic N2 NSCLC was feasible and associated with high response to lymph node metastasis and good survival.

RESUMEN

BACKGROUND: Irinotecan and gemcitabine are effective against non-small cell lung cancer. We conducted a phase I study of the combined use of irinotecan and gemcitabine in previously untreated patients with advanced non-small cell lung cancer to determine dose-limiting toxicities and maximum tolerated dose. METHODS: Patients were treated with irinotecan followed by gemcitabine on days 1 and 8 every 3 weeks. Gemcitabine dose was fixed at 1000 mg/m2, and irinotecan dose was increased from 60 mg/m2. RESULTS: A total of 16 patients was enrolled. Maximum tolerated dose of irinotecan was determined up to level 3 (irinotecan 100 mg/m2). In Japan, the maximum approved weekly dose of irinotecan is 100 mg/m2, so this was the dose that was used. Only very mild hematological and non-hematological toxicities were noted. CONCLUSION: Use of 100 mg/m2 irinotecan followed by 1000 mg/m2 gemcitabine on days 1 and 8 every 3 weeks warrants a phase II study.

RESUMEN

A 62-year-old female patient with renal dysfunction and pulmonary adenocarcinoma developed postoperative recurrence and received carboplatin/pemetrexed and maintenance pemetrexed. As an anaplastic lymphoma kinase (ALK) gene translocation was identified, the therapy was changed to crizotinib. However, the patient's blood creatinine level increased, and her physical status worsened. Alectinib also induced exacerbation of renal dysfunction but was controlled by dose reduction of 140 mg twice daily for 2 weeks treatment and 2 weeks break were repeated, and exhibited a partial response for 16 months. Here, we describe the case in which alectinib treatment had beneficial clinical effects on ALK-positive lung adenocarcinoma, which controlled the adverse renal effects by dose reduction and drug breaks.

RESUMEN

PURPOSE: The combination of carboplatin and etoposide is currently considered the most appropriate regimen for treating elderly patients with small-cell lung cancer (SCLC). Previous reports on elderly patients, 70 years or older, found that the recommended dose was close to that of younger patients. Then, we conducted a phase I study of carboplatin and etoposide in elderly patients, 75 years or older, with SCLC. This study aimed to determine the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT). METHODS: Twenty-six patients fulfilling the eligibility criteria, chemotherapy-naive, performance status (PS) of 0-2, age>or=75, and adequate organ functions were enrolled. Patients' characteristics were: male/female=21/5; PS 0/1/2=9/11/6; median age (range)=78 (75-82); and limited/extensive stage=16/10. The patients intravenously received carboplatin with a target AUC of 4 or 5 mg min/ml (Chatelut formula) on day 1 and etoposide at 80-120 mg/m2 on days 1, 2 and 3. Therapy was repeated four times in every 4 weeks. RESULTS: The MTD of carboplatin/etoposide was AUC=5/80, 4/110, and 4/120. The DLTs were thrombocytopenia, neutropenia, leukopenia, and febrile neutropenia. Overall, grade 4 thrombocytopenia, neutropenia (>or=4 days), leukopenia (>or=4 days), and febrile neutropenia occurred in 27, 20, 7, and 13% of cases at MTD levels, respectively, and 0% at other levels. Twenty of 26 patients showed objective responses (2CR, 18PR; RR=77%). CONCLUSION: A dose of carboplatin of AUC=4 and etoposide of 100 mg/m2 was recommended in this regimen.

RESUMEN

A short tandem repeat (STR) in the intron 1a of paternally imprinted gene, KCNQ1, is evaluated as a new probe for use in parentally imprinting allele (PIA) typing. This typing can determine the inheritance of one allele from father by the methylation difference. Allelic and genotypic frequencies of the STR were determined using samples from 175 unrelated Japanese and 170 unrelated Germans. The polymorphism information contents were 0.652 and 0.634 for the Japanese and the Germans, respectively, indicating usefulness in individual identification. This method was applied to five Japanese families consisting of 19 individuals. Genomic DNA was digested by methylation-sensitive restriction endonucleases, HhaI and HapII, followed by PCR amplification using two-step sandwich primer sets and the products were analyzed on polyacrylamide gel electrophoresis. For all of the families, each child's paternal allele given by PIA typing corresponded to one of the two alleles from father, not the two from mother, that were determined by the STR genotyping. The results demonstrate that this STR probe is feasible for use in PIA typing and that its typing method can contribute to paternity testing.

RESUMEN

Primary mediastinal large B-cell lymphoma (PMLBCL) is one of the subtypes of diffuse large B-cell lymphoma. We experienced a rare case of PMLBCL that exhibited endobronchial involvement. A 33-year-old Japanese female with the chief complaints of epigastralgia, back pain, and nausea visited a primary care hospital. Computed tomography of the chest and abdomen demonstrated a bulky mass in the left anterior mediastinum, multiple pulmonary nodules, axillary lymph node swelling, and a pancreatic tumor. Fiberoptic bronchoscopy showed a white-tinged irregularly shaped endobronchial tumor accompanied by capillary vessel dilation in the left upper lobar bronchus. Taken together, these findings resulted in a diagnosis of PMLBCL.

RESUMEN

Two Japanese females complained of cough and bronchorrhea for which chest radiographs showed infiltrate in the lungs. The patients were subsequently diagnosed as having bronchioloalveolar carcinoma by transbronchial lung biopsy. After receiving systemic chemotherapy, their symptoms were slightly improved. A few months later, their bronchorrhea and dyspnea worsened, and they were then treated with gefitinib, a selective epidermal growth factor receptor tyrosine kinase inhibitor. Bronchorrhea and dyspnea were improved within 24 h after treatment with gefitinib where the improvement was evident after 6 h for one patient and 24 h for the other patient. Thereafter, their radiological findings showed gradual improvement. Rapid relief of bronchorrhea preceded the improvement seen by the radiological findings. These observations suggest that gefitinib may inhibit mucin production as well as exert anti-proliferative activity against bronchioloalveolar carcinoma.

RESUMEN

The parentally imprinted allele (PIA) typing that we have recently developed determines parental alleles at a VNTR locus in the differentially methylated region upstream of the human H19 gene. The usefulness of this typing was demonstrated by its application to blood samples in paternity cases. However, its applicability to other tissue DNA remains to be tested. DNA samples from fifteen different postmortem tissues such as cerebrum, skeletal muscle and skin were examined, all of which were obtained from three autopsy cases 2-11h after death. DNA was digested with a methylation-sensitive HhaI enzyme and diluted solutions of the digests were subjected to the first PCR amplification, providing amplification of only the paternal H19 methylated allele. Subsequent VNTR typing was carried out for the amplified products to determine which allele was of paternal origin. No tissue-dependent difference was observed and all the samples examined, though degraded, were successfully used for determining the paternal allele. These results substantiate the usefulness of PIA typing in forensic examinations. Its application to two identity cases, a burned male body and a male body with adipocere formation, was also shown.

RESUMEN

PURPOSE: Irinotecan, a topoisomerase I inhibitor, is an effective agent for non-small-cell lung cancer (NSCLC). To determine the efficacy and toxicity of irinotecan and carboplatin, we conducted a phase II study in 61 patients with advanced NSCLC. METHODS: Every 4 weeks, the patients received irinotecan 50 mg/m2 (days 1, 8 and 15) and carboplatin (day 1) with a target AUC of 5 mg min/ml using the Chatelut formula. RESULTS: All patients were evaluable for toxicity, and of 59 patients evaluable for response, 20 achieved a partial response and 26 showed no change. The overall response rate was 34% (95% confidence interval 23-48%). Grade 3 or 4 anemia, leukopenia, neutropenia, thrombocytopenia and diarrhea occurred in 32%, 32%, 60%, 25%, and 7%, respectively. The median survival time and 1-year, and 2-year survival rates were 10.0 months, 37.6%, and 15.2%, respectively. CONCLUSIONS: Irinotecan with carboplatin is effective for advanced NSCLC and safe.

RESUMEN

Conventional PCR-based genotyping is useful for forensic testing but cannot be used to determine parental origins of alleles in DNA specimens. Here we describe a novel method of combined conventional genotyping and PIA typing (parentally imprinted allele typing) at a minisatellite region upstream from the H19 locus. The PIA typing uses two sets of primers and DNA digested with methylation-sensitive Hha I enzyme. The first amplification produces only the methylated fragment of paternal H19 allele, and the second detects polymorphism in the minisatellite. Hence, this distinguishes paternal and maternal alleles by difference in the DNA methylation. Furthermore, the polymorphism in this polymorphic locus was examined using 199 unrelated Japanese and 171 unrelated Germans, their polymorphism information content being 0.671 and 0.705, respectively. Feasibility of this typing is demonstrated for six families, and the usefulness is shown by application to paternity testing.

RESUMEN

PURPOSE: To investigate the efficacy of erlotinib versus docetaxel in previously treated patients with advanced non-small-cell lung cancer (NSCLC) in an epidermal growth factor receptor (EGFR) -unselected patient population. PATIENTS AND METHODS: The primary end point was progression-free survival (PFS). Secondary end points included overall survival (OS), response rate, safety, and analyses on EGFR wild-type tumors. Patients with stage IIIB or IV NSCLC, previous treatment with one or two chemotherapy regimens, evaluable or measurable disease, and performance status of 0 to 2 were eligible. RESULTS: From August 2009 to July 2012, 150 and 151 patients were randomly assigned to erlotinib (150 mg daily) and docetaxel (60 mg/m(2) every 3 weeks), respectively. EGFR wild-type NSCLC was present in 109 and 90 patients in the erlotinib and docetaxel groups, respectively. Median PFS for erlotinib versus docetaxel was 2.0 v 3.2 months (hazard ratio [HR], 1.22; 95% CI, 0.97 to 1.55; P = .09), and median OS was 14.8 v 12.2 months (HR, 0.91; 95% CI, 0.68 to 1.22; P = .53), respectively. In a subset analysis of EGFR wild-type tumors, PFS for erlotinib versus docetaxel was 1.3 v 2.9 months (HR, 1.45; 95% CI, 1.09 to 1.94; P = .01), and OS was 9.0 v 10.1 months (HR, 0.98; 95% CI, 0.69 to 1.39; P = .91), respectively. CONCLUSION: Erlotinib failed to show an improvement in PFS or OS compared with docetaxel in an EGFR-unselected patient population.
