Career adaptability among new oncology nurses: A longitudinal exploration.

AIM: This study aims to explore the longitudinal predictive effect of self-awareness on career adaptability in new nurses at a tumor specialty hospital and the mediating mechanisms of work readiness and transition shock. BACKGROUND: Career adaptability is crucial for the personal development of nurses and also intricately linked to the retention rates among newcomers in oncology nursing. Inadequate career adaptability contributes to higher turnover, which in turn exacerbates the shortage of qualified nursing personnel in this field. There is a pressing need for dedicated research and interventions that support new nurses, especially in specialized areas like oncology, to promote their well-being and career advancement. Comprehending these challenges is essential for devising effective strategies that will retain nursing talent and ensure the sustainability of a robust healthcare workforce. METHODS: Longitudinal data from four follow-up surveys were collected from 248 new clinical nurses at the National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences, and Peking Union Medical College. Mediation analyses using R 4.1.2 were conducted to examine the pathways between self-awareness, work readiness, transition shock, and career adaptability. CONCLUSIONS: Self-awareness not only directly predicts career adaptability but also influences it through the bidirectional and chained mediating pathways of work readiness and transition shock. IMPLICATIONS FOR NURSING AND HEALTH POLICY: These findings equip nursing managers with flexible strategies to foster and enhance nurses' career adaptability, providing targeted support as nurses assimilate into their clinical roles. This not only strengthens workforce stability but also mitigates turnover, ultimately reinforcing the healthcare workforce.

Pathological response and tumor stroma immunogenic features predict long-term survival in non-small cell lung cancer after neoadjuvant chemotherapy.

PURPOSE: Major pathological response (MPR) has become a surrogate endpoint for overall survival (OS) in non-small cell lung cancer (NSCLC) after neoadjuvant therapy, however, the prognostic histologic features and optimal N descriptor after neoadjuvant therapy are poorly defined. METHODS: We retrospectively analyzed data from 368 NSCLC patients who underwent surgery after neoadjuvant chemotherapy (NAC) from January 2010 to December 2020. The percentage of residual viable tumors in the primary tumor, lymph nodes (LN), and inflammation components within the tumor stroma were comprehensively reviewed. The primary endpoint was OS. RESULTS: Of the 368 enrolled patients, 12.0% (44/368) achieved MPR in the primary tumor, which was associated with significantly better OS (HR, 0.36 0.17-0.77, p = 0.008) and DFS (HR = 0.59, 0.36-0.92, p = 0.038). In patients who did not have an MPR, we identified an immune-activated phenotype in primary tumors, characterized by intense tumor-infiltrating lymphocyte or multinucleated giant cell infiltration, that was associated with similar OS and DFS as patients who had MPR. Neoadjuvant pathologic grade (NPG), consisting of MPR and immune-activated phenotype, identified 30.7% (113/368) patients that derived significant OS (HR 0.28, 0.17-0.46, p < 0.001) and DFS (HR 0.44, 0.31-0.61, p < 0.001) benefit from NAC. Moreover, the combination of NPG and the number of positive LN stations (nS) in the multivariate analysis had a higher C-index (0.711 vs. 0.663, p < 0.001) than the ypTNM Stage when examining OS. CONCLUSION: NPG integrated with nS can provide a simple, practical, and robust approach that may allow for better stratification of patients when evaluating neoadjuvant chemotherapy in clinical practice.

Effects of burnout and work engagement in the relationship between self-efficacy and safety behaviours-A chained mediation modelling analysis.

AIMS: To explore the current situation, influencing factors and pathways of safety behaviour of nurses in tumour specialized hospitals, in order to provide a theoretical basis for managers to manage and train nurses, improve their safety behaviour level and ensure medical safety. DESIGN: An anonymous cross-sectional survey. METHOD: A total of 2147 nurses from Grade A cancer hospitals in 15 provinces of China were selected by a convenient sampling method. Questionnaires were collected through the Questionnaire Star platform. Nurses' safety behaviour was measured using the nurse Safety Behaviour Scale, Self-efficacy by the General Self-efficacy Scale, and nurses' occupational burnout was measured by the occupational Burnout Scale, and work engagement through the the Work Engagement Scale. Structural equation modelling was used to test the relationship among nurses' safety behaviour, general self-efficacy, occupational burnout and work engagement. SPSS25.0 software was used to test the relationship among the safety behaviour of nurses, general self-efficacy, occupational burnout and work engagement. RESULTS: The total score of safety behaviour of nurses was 55.45 ± 6.879, the total score of general self-efficacy was 31.39 ± 5.729, the total score of occupational burnout was 44.99 ± 26.587, and the total score of work engagement was 38.48 ± 13.433; the scores of the Nurse Safety Behaviour Scale, Self-Efficacy Scale, and Work Engagement Scale were positively correlated (all p < .001); the occupational burnout scale was negatively correlated with the scores of self-efficacy scale, work engagement scale and nurse safety behaviour scale (all p < .001); Structural equation model analysis shows that self-efficacy and work engagement have a direct positive impact on nurse safety behaviour(ß = .103, ß = .096, all p < .001); Occupational burnout has a direct negative impact on self-efficacy, work engagement and nurse safety behaviour(ß = -.371, ß = -.413, ß = -.328 all p < .001). Bootstrap analysis showed that occupational burnout and job involvement had a significant chain mediating effect between self-efficacy and the safety behaviour of nurses (95% CI: 0.148-0.21). The total effect of self-efficacy on the safety behaviour of nurses was 0.283 (p < .001, 95% CI: 0.225-0.301), the direct effect was 0.096 (p < .001, 95% CI: 0.042-0.15), and the indirect effect was 0.179 (p < .001, 95% CI: 0.085-0.215), The mediating effect accounted for 63.3% of the total effect size. CONCLUSION: Occupational burnout and work engagement play a partial mediating role between self-efficacy and nurse safety behaviour. It is necessary to strengthen training on nurse safety culture awareness, improve the nurse self-efficacy and work engagement, reduce nurse occupational burnout, and thereby improve the level of nurses' safety behaviour.

Multi-omics analysis unravels the underlying mechanisms of poor prognosis and differential therapeutic responses of solid predominant lung adenocarcinoma.

Background: Solid predominant adenocarcinoma (SPA) has been reported to be a subtype with poor prognosis and unsatisfactory response to chemotherapy and targeted therapy in lung adenocarcinoma (LUAD). However, the underlying mechanisms remain largely unknown and the suitability of immunotherapy for SPA has not been investigated. Methods: We conducted a multi-omics analysis of 1078 untreated LUAD patients with clinicopathologic, genomic, transcriptomic, and proteomic data from both public and internal cohorts to determine the underlying mechanisms of poor prognosis and differential therapeutic responses of SPA and to investigate the potential of immunotherapy for SPA. The suitability of immunotherapy for SPA was further confirmed in a cohort of LUAD patients who received neoadjuvant immunotherapy in our center. Results: Along with its aggressive clinicopathologic behaviors, SPA had significantly higher tumor mutation burden (TMB) and number of pathways altered, lower TTF-1 and Napsin-A expression, higher proliferation score and a more immunoresistant microenvironment than non-solid predominant adenocarcinoma (Non-SPA), accounting for its worse prognosis. Additionally, SPA had significantly lower frequency of therapeutically targetable driver mutations and higher frequency of EGFR/TP53 co-mutation which was related to resistance to EGFR tyrosine kinase inhibitors, indicating a lower potential for targeted therapy. Meanwhile, SPA was enriched for molecular features associated with poor response to chemotherapy (higher chemoresistence signature score, lower chemotherapy response signature score, hypoxic microenvironment, and higher frequency of TP53 mutation). Instead, muti-omics profiling revealed that SPA had stronger immunogenicity and was enriched for positive biomarkers for immunotherapy (higher TMB and T cell receptor diversity; higher PD-L1 expression and more immune cell infiltration; higher frequency of gene mutations predicting efficacious immunotherapy, and elevated expression of immunotherapy-related gene signatures). Furthermore, in the cohort of LUAD patients who received neoadjuvant immunotherapy, SPA had higher pathological regression rates than Non-SPA and patients with major pathological response were enriched in SPA, confirming that SPA was more prone to respond to immunotherapy. Conclusions: Compared with Non-SPA, SPA was enriched for molecular features associated with poor prognosis, unsatisfactory response to chemotherapy and targeted therapy, and good response to immunotherapy, indicating more suitability for immunotherapy while less suitability for chemotherapy and targeted therapy.

Risk and prognosis of secondary thoracic cancers after radiation therapy for esophageal cancer.

BACKGROUND AND AIM: Radiation therapy (RT) is a crucial modality for the local control of esophageal cancer (EC), but the effect of RT on the development of secondary thoracic malignancies is still unclear. This study aims to identify the association between RT for the treatment of primary EC and subsequent secondary thoracic cancer (STC). METHODS: The primary EC patients were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. Fine-Gray competing risk regression and standardized incidence ratio (SIR) were used to evaluate the radiotherapy-associated cancer risk. Overall survival (OS) was compared by Kaplan-Meier analysis. RESULTS: A total of 40 255 EC patients from the SEER database were identified, of which 17 055 patients (42.37%) did not receive radiotherapy (NRT) and 23 200 patients (57.63%) had been treated with RT. After 12 months of latency, 162 patients (0.95%) in the NRT group and 272 patients (1.17%) in the RT group developed STC. The incidences of the RT group were significantly higher than the NRT group. Patients who have primary EC were at an increased risk of developing STC (SIR = 1.79, 95% CI: 1.63-1.96). The SIR of STC was 1.37 (95% CI: 1.16-1.60) in the NRT group and 2.10 (95% CI: 1.87-2.34) in the RT group. The OS of STC patients in the RT group was significantly lower than the NRT group (P = 0.006). CONCLUSION: The RT for primary EC was associated with higher risks of developing STC than patients unexposed to radiotherapy. The EC patients treated with RT, especially young patients, require long-term monitoring of the risk of STC.

Effect of histology on the efficacy of immune checkpoint inhibitors in advanced non-small cell lung cancer: A systematic review and meta-analysis.

Background: Little is known about the effect of histology on the efficacy of immune checkpoint inhibitors (ICI) in non-small-cell lung cancer (NSCLC). We conducted a systematic review and meta-analysis to assess the potential differences in the efficacy of ICIs between squamous NSCLC (SQ-NSCLC) and non-squamous NSCLC (non-SQ-NSCLC). Methods: Systematic searches of PubMed, Embase, Scopus, and Cochrane Library databases were conducted. All randomized clinical trials of ICIs with available hazard ratios (HR) for progression-free survival (PFS) or overall survival (OS) according to histology were included. The primary endpoint was to assess the difference in the efficacy of ICIs between SQ-NSCLC and non-SQ-NSCLC, measured by the ratio of the HR in SQ-NSCLC to the HR in non-SQ-NSCLC (RHR). Results: A total of 40 trials were included in the meta-analysis. ICI monotherapy could improve OS in both SQ-NSCLC (OS-HR 0.71, 95% CI 0.65-0.77) and non-SQ-NSCLC (OS-HR 0.80, 95% CI 0.73-0.87) while OS benefit was larger in SQ-NSCLC (OS-RHR 0.89, 95% CI 0.80-0.99). In terms of PFS, ICI monotherapy could reduce the risk of progression by 35% (PFS-HR 0.65, 95% CI 0.56-0.77) in SQ-NSCLC while the PFS benefit was smaller (10%) and not statistically significant in non-SQ-NSCLC (PFS-HR 0.90, 95% CI 0.76-1.07). Similarly, ICI-based combination treatments could reduce the risk of both progression and death in SQ-NSCLC (OS-HR 0.70, 95% CI 0.61-0.80; PFS-HR 0.56, 95% CI 0.48-0.65) and non-SQ-NSCLC (OS-HR 0.78, 95% CI 0.74-0.83; PFS-HR 0.63, 95% CI 0.57-0.69) while the survival benefits were larger in SQ-NSCLC (OS-RHR 0.83, 95% CI 0.70-0.99; PFS-RHR 0.82, 95% CI 0.70-0.96). Conclusions: ICIs could deliver survival benefits in both SQ-NSCLC and non-SQ-NSCLC while the magnitude of survival benefits was histology-dependent. Future researches should consider the effect of histology on the efficacy of ICIs. Systematic Review Registration: https://www.crd.york.ac.uk/prospero/, identifier [CRD42022299603].

Comparison of Two Proposed Changes to the Current Nodal Classification for Non--small Cell Lung Cancer Based on the Number and Ratio of Metastatic Lymph Nodes.

BACKGROUND: The current nodal classification is unsatisfactory in distinguishing the prognostically heterogeneous N1 or N2 non-small cell lung cancer (NSCLC). RESEARCH QUESTION: Is the combination of the current N category and the number of metastatic lymph nodes (N-#number) or the combination of the current N category and the ratio of the number of positive to resected lymph nodes (N-#ratio) better than the current N category alone? STUDY DESIGN AND METHODS: We identified 2,162 patients with N1 or N2 NSCLC from the Surveillance, Epidemiology, and End Results database (2004-2016). We classified these patients into three N-#number categories (N-#number-1, N-#number-2a, N-#number-2b) and three N-#ratio categories (N-#ratio-1, N-#ratio-2a, N-#ratio-2b). Lung cancer-specific survival (LCSS) were compared using the Kaplan-Meier method. The prognostic significance of the new nodal classifications was validated across each tumor size category (≤3 cm, 3-5 cm, 5-7cm, >7 cm). Cox proportional hazards regression was used to evaluate the association between each nodal classification and LCSS. RESULTS: The survival curves showed clear differences between each pair of N-#number and N-#ratio categories. A significant tendency toward the deterioration of LCSS from N-#number-1 to N-#number-2b was observed in all tumor size categories. However, the differences between each pair of N-#ratio categories were significant only in tumors from 3 to 7 cm. Although all three nodal classifications were independent prognostic indicators, the N-#number classification provided more accurate prognostic stratifications compared with the N-#ratio classification and the current nodal classification. INTERPRETATION: The N-#number classification followed by the N-#ratio classification might be better prognostic determinants than the current nodal classification in prognostically heterogeneous N1 or N2 NSCLC.
