Reporting of ethical considerations in clinical trials in Chinese nursing journals

Background: It is acknowledged that publishers now require all primary research papers to demonstrate that they have obtained ethical approval for their research. Objectives: To assess the rate of reporting of ethical approval in clinical trials in core nursing journals in mainland China. Research design: A retrospective observational study. Participants: All clinical trials published in all of the 12 core nursing periodicals from 2016 edition China Science and Technology Journal Citation Report (core version) between 2013 and 2016 were retrieved by hand to explicate rate of reporting ethical approval and informed consent. Ethical considerations: The study did not require approval from the research ethics committee as it did not involve human subjects or records. Results: In total, 40,278 papers were published in 12 nursing periodicals between 2013 and 2016. Out of these, 9488 (23.6%) focused on clinical trials. Informed consent obtained from patients or the legally authorized representative was reported in 51.8% of clinical trials. Notably, only 27.4% of clinical trials reported that they had obtained written consent. Furthermore, 25.9% of clinical trials described ethical approval; however, the rate of reporting informed consent and ethical approval in these 12 nursing journals in China during 4 years from 2013 to 2016 improved markedly, with 38.1%, 44.0%, 59.0% and 66.6%, respectively (p<0.001), and 17.6%, 21.9%, 28.6% and 35.8%, respectively (p<0.001). In addition, both reporting informed consent and reporting written informed consent had a positive significant correlation with the reporting ethical approval (p<0.05 or p<0.01). Conclusion: Chinese scientific nursing journals have improved the rate of reporting informed consent and ethical approval in clinical trials during the last 4 years. However, it should be noted that nearly half of clinical trials still did not report either ethical approval or whether informed consent was obtained. Efforts from editors, researchers, sponsors and authors are needed to ensure the transparency of ethical scrutiny and adherence to ethical guidelines in publishing clinical trials in Chinese nursing journals

Clinical and molecular characteristics of Chinese non-small cell lung cancer patients with ERBB2 transmembrane domain mutations.

Transmembrane domain (TMD) mutations of ERBB2 have previously been reported in lung cancer patients in addition to well-studied kinase domain (KD) mutations, which may stabilize ERBB2 heterodimerization with other EGFR family members and favor a kinase active conformation. However, the frequency and clinical significance of ERBB2 TMD mutations in Chinese population is unknown. We prospectively analyzed the next-generation sequencing data of 34&nbsp;368 Chinese lung cancer patients with different sample types, including tumor tissue, plasma, cerebrospinal fluid, and pleural effusion. Patients clinical characteristics and treatment history were retrieved from the database for further evaluation. Our findings show that ERBB2 V659/G660 mutations were detected at a frequency of 0.13% (45/34&nbsp;368), of which the most frequent was V659D/E (88.9%), with a trend in nonsmokers and male. Moreover, 18% of patients (8/45) showed EGFR and/or ERBB2 amplification, whereas nine patients presented EGFR L858R or exon19 deletion. Interestingly, novel ERBB3 TMD mutation I646R was found coexisting in three patients with ERBB2 V659D and one patient with ERBB2 G660D, which might influence its heterodimerization with ERBB2 and further activate ERBB2. Four ERBB2 TMD mutation-positive patients received afatinib monotherapy or combination therapy, but showed variable responses. One patient with V659E responded well to ERBB2 inhibitor lapatinib plus capecitabine as well as subsequent afatinib treatment upon progression. Our study provides valuable insights into the distribution of ERBB2 TMD mutations by employing the largest Asian lung cancer cohort thus far. Patients with ERBB2 TMD mutations who received afatinib, a pan-ERBB inhibitor, demonstrated mixed responses, posing the urgent need to develop more effective therapeutic strategy for patients who carry ERBB2 TMD mutations
