ABSTRACT
@#The increasing number of pulmonary nodules being detected by computed tomography scans significantly increase the workload of the radiologists for scan interpretation. Limitations of traditional methods for differential diagnosis of pulmonary nodules have been increasingly prominent. Artificial intelligence (AI) has the potential to increase the efficiency of discrimination and invasiveness classification for pulmonary nodules and lead to effective nodule management. Chinese Experts Consensus on Artificial Intelligence Assisted Management for Pulmonary Nodule (2022 Version) has been officially released recently. This article closely follows the context, significance, core implications, and the impact of future AI-assisted management on the diagnosis and treatment of pulmonary nodules. It is hoped that through our joint efforts, we can promote the standardization of management for pulmonary nodules and strive to improve the long-term survival and postoperative life quality of patients with lung cancer.
ABSTRACT
Even patients after standard surgery and adjuvant chemotherapy still have a high risk of recurrence and metastasis. With the success of immunotherapy in advanced non-small cell lung cancer (NSCLC), the application of immunotherapy in locally advanced NSCLC has being investigated to reduce the recurrence and metastasis. Pre-clinical studies and several phase II clinical studies had provided theoretical support and clinical evidence for neoadjuvant immunotherapy for NSCLC. This review describes the mechanism of neoadjuvant immuno-chemotherapy, summarizes up-to-date clinical studies, and analyzes efficiency and feasibility of neoadjuvant immune monotherapy or immuno-chemotherapy. Results from four studies (NCT02259621, NEOSTAR, LCMC3 and ChiCTR-OIC-17013726) showed efficiency and feasibility of neoadjuvant anti-programmed cell death 1 (PD-1)/programmed cell death ligand 1 (PD-L1) monotherapy. Neoadjuvant nivolumab plus ipilimumab achieved higher major pathological response rate than nivolumab monotherapy. However, the combination of nivolumab plus ipilimumab led to more severe adverse events as is seen in the NEOSTAR trial. Results from NCT02716038, SAKK 16/14 and NADIM studies suggest that the pathological response rate of neoadjuvant immune-chemotherapy is higher than neoadjuvant immune checkpoint inhibitor monotherapy. This review also elaborates the mechanism of chemotherapy combined with immunotherapy, and discusses the efficacy evaluation after neoadjuvant immunotherapy. .
ABSTRACT
Objective The study was designed to investigate the serum levels of HE4 in patients with lung cancer,and explore its prognostic value.Methods Blood samples of 106 healthy adults and 191 patients with lung cancer before treatment were measured by means of ELISA for HE4 levels in different stages and pathological types,for analyzing prognostic effect of HE4.Results The serum levels of HE4 in patients with lung cancer (median level 91.63 pmol/L) were significantly higher than control group (median level 56.42 pmol/L) (U =3 081.00,P ＜ 0.05).AUC of serum HE4 was 0.85,with a cut-off value of 82.70 pmol/L (specificity =95.31％,sensitivity =62.32％).HE4 expression was not statistically related to clinical stage and pathological types of lung cancer.The median overall survival (mOS) was 36.87 months in the HE4-low group and 30.43 months in the HE4-high group (P ＜0.05),respectively.HE4 level was an independent prognostic factor for overall survival (HR =2.15,95％ CI 1.49-3.12,P ＜ 0.05).Conclusions The prognosis of patients with high HE4 expression is poor.Therefore,it might be necessary for patients with high level of HE4 to receive more aggressive adjuvant therapy.
