Clinical Progress in the Immunotherapy of Small Cell Lung Cancer / 中国肺癌杂志

Small cell lung cancer is a kind of malignant tumor with strong invasiveness and poor prognosis, and the classic therapeutic modality of the disease remains multidisciplinary and comprehensive treatment. Treatment options for small cell lung cancer have been stalled for a long time, and new opportunities have emerged in recent years due to the development and initial experience of immunotherapeutic drugs. Clinical trials of some selected immune checkpoint inhibitors have confirmed the efficacy and safety in small cell lung cancer. Based on the results of phase III clinical trials (Impower133 and CASPIAN), Atezolizumab or Durvalumab in combination with chemotherapy has been approved by the U.S. Food and Drug Administration for the first-line treatment of extensive-stage small cell lung cancer. Clinical trials involving immune checkpoint inhibitors are being actively carried out and provide different perspectives for the management of small cell lung cancer. This article aimed to review the clinical progress in immunotherapy of small cell lung cancer.

Research progress on the cardiorenal protection of non-steroid mineralocorticoid receptor antagonists in patients with chronic kidney disease / 生理学报

Mineralocorticoid receptor antagonists not only are used as a diuretics to treat essential hypertension, but also protect the heart and kidney by inhibiting inflammation and fibrosis. Since the discovery of spironolactone, the first generation of mineralocorticoid receptor antagonist, two types of non-steroid mineralocorticoid receptor antagonists (finerenone and esaxerenone) approved for clinical use have been developed, which have the advantages of high affinity, high selectivity and balanced distribution in heart and kidney, and can be used in clinic as a cardiorenal protective drug. In this paper, the development history of mineralocorticoid receptor antagonists was reviewed, and the pathophysiological mechanism of inflammation and fibrosis caused by mineralocorticoid receptors and the similarities and differences of different generations of mineralocorticoid receptor antagonists were analyzed. In particular, the phase III clinical research evidence of finerenone and esaxerenone was discussed. This paper also reviews the research progress of cardiorenal protection of non-steroid mineralocorticoid receptor antagonists in patients with chronic kidney disease.

Evaluation of safety and immunogenicity of hepatitis E vaccine in maintenance hemodialysis patients / 中华预防医学杂志

Objective: To evaluate the safety and immunogenicity of hepatitis E vaccine(HEV)in Maintenance hemodialysis(MHD)patients. Methods: Based on an open-labeled controlled trial, from May 2016 to March 2018, 35 eligible MHD patients were recruited in the Hemodialysis Center of Zhongshan Hospital Affiliated to Xiamen University as the experimental group, and 70 MHD patients with matched age, gender and underlying diseases as the control group. The experimental group received HEV at 0, 1 and 6 months according to the standard vaccination procedures, while the control group received routine diagnosis and treatment without vaccine and placebo injection to observe the safety and immunogenicity of the vaccine. The safety of vaccine in MHD population was evaluated by the incidence of adverse reactions/events in the experimental and control groups. The immunogenicity of HEV in MHD patients was evaluated by comparing the data from the phase Ⅲ clinical trial. Results: The overall incidence of adverse reactions/events was 17.1% (18/105), and there were no grade 3-4 adverse reactions/events related to vaccination. In the experimental group, the incidence of local adverse reactions/events was 20.0% (7/35), and the incidence of systemic adverse reactions/events was 17.1% (6/35).There was no significant difference in the incidence of systemic adverse reactions/events between the experimental group and the control group (P>0.05). There were 23 patients receiving 3 doses with the standard schedule. The positive rate of HEV-IgG antibody was 100% and the GMC was 14.47(95%CI:13.14-15.80) WU/ml, which showed no significant difference compared with the 46 patients in Phase Ⅲ clinical trial (t=-1.04, P>0.05). Conclusion: Recombinant HEV has good safety and immunogenicity in MHD patients.

JCOG lung cancer surgery trial series: review and interpretation / 中华肿瘤杂志

Surgery is so far the most effective treatment for early-stage non-small cell lung cancer (NSCLC). Since the 1990s, the pathology spectrum of early-stage lung cancer has gradually changed because of the increased detection of ground-glass opacity (GGO). The findings from preoperative thin-section computed tomography are strong predictors for the invasiveness and lymph node involvement of GGO, and limited surgery is believed to be implemented safely for radiological less invasive lesions, which calls into question the dominance of lobectomy. After the JCOG0201 trial establishing the radiologic criteria of pathological noninvasiveness for lung adenocarcinoma, the Japan Clinical Oncology Group (JCOG) and the West Japan Oncology Group (WJOG) have successively carried out a series of prospective imaging-guided trials to investigate the optimal surgical procedure for early-stage lung cancer. JCOG0804, was a single-arm, non-randomized, confirmatory trial to evaluate the efficacy and safety of sublobar resection (wedge resection and segmentectomy) for GGO dominant peripheral lung cancer. The primary end point was 5-year relapse-free survival. JCOG0802/WJOG4607L, was a multicentre, open-label, phase 3, randomized, controlled, non-inferiority trial to investigate if segmentectomy was non-inferior to lobectomy in patients with small-sized peripheral NSCLC. The primary endpoint was 5-year overall survival. JCOG1211 was also a non-randomized confirmatory trial to confirm the efficacy of a segmentectomy for clinical T1N0 lung cancer with dominant GGO. The primary endpoint was 5-year relapse-free survival. The findings of JCOG0804 and JCOG0802, and the primary analysis results of JCOG1211 have been officially published. This article systematically reviewed and interpreted the results of the JCOG lung cancer surgery trial series.

Evaluación de la calidad de vida de pacientes con cáncer de pulmón de células no pequeñas tratados con la vacuna CIMAvaxEGF® / Evaluation of quality of life in patients with non-small cell lung cancer treated with CIMAvaxEGF® vaccine

Este reporte corresponde al análisis de la calidad de vida de los pacientes que se incluyeron en el ensayo clínico fase III de evaluación de la vacuna CIMAvaxEGF® en cáncer de pulmón de células no pequeñas. La calidad de vida se evaluó empleando los cuestionarios EORTC QLQ-C30 y QLQ-C13, al inicio y cada 3 meses hasta el fallecimiento del paciente a criterio del investigador. Para comparar las medianas entre los dos grupos se utilizó la prueba no paramétrica de Mann-Whitney. Las comparaciones entre el nivel basal y los diferentes tiempos de seguimiento se realizaron a través de la prueba no paramétrica de Wilcoxon. El cuestionario QLQ-C30 evidenció un beneficio en cuanto a calidad de vida para el grupo vacunado con la vacuna CIMAvaxEGF® en las escalas funcionales (global, rol y social), en las escalas de síntomas de la enfermedad y del tratamiento (dolor) se observó que mejora la calidad de los mismos a favor de los pacientes tratados con la vacuna CIMAvaxEGF®. El cuestionario QLQ-C13, también evidenció ventajas para el grupo vacunado desde el punto de vista de beneficio clínico en los síntomas (disnea, disfagia, alopecia y dolor en el pecho). Se señala como significativo que disminuye la hemoptisis y la tos en el grupo vacunado, observándose un empeoramiento en el grupo control(AU)

This report corresponds to quality of life analysis of patient with non-small cell lung cancer included in the phase III clinical trials Evaluation of CIMAvaxEGF® vaccine in lung cancer. The quality of life was evaluate using the EORTC questionnaires QLQ-C30 y QLQ-C13, at the beginning and every 3 months. To compare the median between two groups the Mann-Whitney non-parametric test was used. To compare the baseline and different follows times the Wilcoxon non-parametric test was used. The QLQ-C30 questionnaire showed a benefit in terms of the quality of life for the CIMAvaxEGF® vaccine group on the functional scores (global, role and social) and symptoms of the disease (pain). The QLQ-LC13 questionnaire showed a benefit in terms of the quality of life for the CIMAvaxEGF® vaccine group on the symptoms scores (dyspnea, dysphagia, alopecia and chest pain). It is noted as significant that the hemoptysis decreases in the group vaccinated as well as the dysphagia, the cough and the dyspnea observing a worsening in the control group(AU)

Vacunas SARS CoV-2, estudios en fase III / SARS CoV-2 vaccine studies currently in phase III

Resumen La enfermedad por coronavirus 2019, causada por el virus SARS-CoV2, fue declarada pandemia en marzo de 2020 por la OMS. La proteína S, de la superficie viral ha sido identificada como antígeno óptimo para el desarrollo de vacunas. En pandemia, el proceso tradicional de desarrollo de vacunas ha debido acelerarse para avanzar en una respuesta adecuada al problema, acortando los tiempos. La seguridad, inmunogenicidad, protección frente a la infección, fenómeno de "aumento dependiente de anticuerpos", duración de la protección se estudian en paralelo, a diferencia de la manera tradicional en que se llevaba a cabo en etapas sucesivas. Actualmente en Fase III hay 4 tipos vacunas: inactivadas; en base a proteínas purificadas o recombinantes, en base a ácidos nucleicos ADN/ARN y en base a vectores virales. El objetivo de esta revisión es conocer los estudios que preceden a las vacunas que actualmente están en estudios de Fase III y describir las características principales de estos estudios. Actualmente el mundo se encuentra en una situación inédita en el último siglo. Dentro las opciones para enfrentar este hecho, una vacuna o idealmente varias, seguras, eficaces e inmunogénicas, parecen ser una de las mejores alternativas para retomar en un plazo razonable la normalidad perdida.

Abstract The coronavirus disease 2019, caused by the SARS-CoV2 virus, was declared a pandemic in March 2020 by the WHO. Protein S from the viral surface has been identified as the optimal antigen for vaccine development. In a pandemic, the traditional vaccine development process has had to be accelerated to advance in an adequate response to the problem, shortening the times. Safety, immunogenicity, protection against infection, antibody dependent enhancement phenomena and duration of protection are studied in parallel, unlike the traditional way in which it was carried out in successive stages. Currently in Phase III there are 4 types of vaccines: inactivated; based on purified or recombinant proteins, based on DNA / RNA nucleic acids and based on viral vectors. The objective of this review is to understand the studies that precede the vaccines that are currently in Phase III studies and to describe the main characteristics of these studies. Currently the world is in a situation unprecedented in the last century. Among the options to face this fact, one vaccine or, ideally, several, safe, effective and immunogenic, seem to be one of the best alternatives to regain lost normality within a reasonable time.
