AI Article Synopsis

  • Neoadjuvant immunochemotherapy was analyzed as a treatment for non-small cell lung cancer (NSCLC) through a meta-analysis of 60 studies involving 3,632 patients.
  • The results indicated that neoadjuvant immunochemotherapy outperformed standard chemotherapy in terms of pathological complete response (pCR), major pathological response (MPR), and overall response rate (ORR), while also having fewer surgical complications.
  • The analysis suggests that this approach provides effective and safe treatment options for operable NSCLC patients, especially those with advanced stage or specific tumor types.

Article Abstract

Background: Neoadjuvant immunochemotherapy may benefit patients with non-small cell lung cancer (NSCLC), but its impact requires further investigation.

Methods: A meta-analysis was conducted. PubMed, Embase, Web of Science, and the Cochrane Library were searched. The study was registered in PROSPERO (registration no. CRD42022360893).

Results: 60 studies of 3,632 patients were included. Comparing with neoadjuvant chemotherapy, neoadjuvant immunochemotherapy showed higher pCR (RR: 4.71, 95% CI: 3.69, 6.02), MPR (RR, 3.20, 95% CI: 2.75, 3.74), and ORR (RR, 1.46, 95% CI: 1.21, 1.77), fewer surgical complications (RR: 0.67, 95%CI: 0.48, 0.94), higher R0 resection rate (RR: 1.06, 95%CI: 1.03, 1.10, I = 52%), and longer 1-year and 2-year OS, without affecting TRAEs. For neoadjuvant immunochemotherapy in NSCLC, the pooled pCR rate was 0.35 (95% CI: 0.31, 0.39), MPR was 0.59 (95% CI: 0.54, 0.63), and ORR was 0.71 (95% CI: 0.66, 0.76). The pooled incidence of all grade TRAEs was 0.70 (95% CI: 0.60, 0.81), and that of >= grade 3 TRAEs was 0.24 (95% CI: 0.16, 0.32). The surgical complications rate was 0.13 (95% CI: 0.07, 0.18) and R0 resection rate was 0.98 (95% CI: 0.96, 0.99). The pooled 1-year OS was 0.97 (95%CI: 0.96, 0.99), and 2-year OS was 0.89 (95%CI: 0.83, 0.94). Patients with squamous cell carcinoma, stage III or higher PD-L1 performed better. Notably, no significant differences were observed in pCR, MPR, and ORR between 2 or more treatment cycles. Pembrolizumab-, or toripalimab-based neoadjuvant immunochemotherapy demonstrated superior efficacy and tolerable toxicity.

Conclusion: According to our analysis, reliable efficacy, safety, and survival of neoadjuvant immunochemotherapy for operable NSCLC were demonstrated.

Background: To date, there remains a paucity of comparative investigations pertaining to preoperative immunochemotherapy and conventional chemotherapy in the context of limited-stage small-cell lung cancer (LS-SCLC) patients. This study conducted a comprehensive comparative assessment concerning the safety and efficacy profiles of preoperative immunochemotherapy and chemotherapy in individuals diagnosed with stage I-IIIB SCLC.

Methods: This investigation collected 53 consecutive patients diagnosed with LS-SCLC spanning stage I to IIIB who underwent preoperative immunochemotherapy or conventional chemotherapy at our hospital from January 2019 to July 2021.

Adjuvant immunotherapy after neoadjuvant immunochemotherapy and esophagectomy for esophageal squamous cell carcinoma: a real-world study.

Front Immunol

Department of Thoracic Oncological Surgery, Zhejiang Cancer Hospital, Hangzhou Institute of Medicine (HIM), Chinese Academy of Sciences, Hangzhou, China.

Background: The role of immunotherapy in the adjuvant setting seems promising in recent years. As per the findings of the CheckMate 577 trial, patients with esophageal cancer (EC) who had neoadjuvant chemoradiation with residual pathologic disease should be considered adjuvant immunotherapy (AIT). However, it is unknown if individuals with esophageal squamous cell carcinoma (ESCC) who have received neoadjuvant immunochemotherapy (NICT) followed by radical surgery also require AIT.

Background: Immunochemotherapy is inevitably accompanied with treatment-related adverse events (TRAEs). However, TRAEs are typically assessed at a single time point, overlooking the complexity of TRAE trajectories over time. This study aimed to characterize TRAE trajectories during multi-cycle neoadjuvant immunochemotherapy (nICT) and identify potential prognostic factors for patients with esophageal squamous cell carcinoma (ESCC).

TLS and immune cell profiling: immunomodulatory effects of immunochemotherapy on tumor microenvironment in resectable stage III NSCLC.

Background: The use of programmed death-1 (PD-1) inhibitors in the neoadjuvant setting for patients with resectable stage III NSCLC has revolutionized this field in recent years. However, there is still 40%-60% of patients do not benefit from this approach. The complex interactions between immune cell subtypes and tertiary lymphoid structures (TLSs) within the tumor microenvironment (TME) may influence prognosis and the response to immunochemotherapy.

Neoadjuvant immunochemotherapy-a promising strategy for primary pulmonary lymphoepithelioma-like carcinoma.

Objective: Neoadjuvant immunochemotherapy has been a promising choice for patients with locally advanced non-small cell cancer (NSCLC). However, whether neoadjuvant immunochemotherapy impacted the subsequent surgical or pathological outcomes of patients with pulmonary lymphoepithelioma-like carcinoma (PLELC) remains relatively unknown. This study aimed to evaluate the safety and efficacy of neoadjuvant immunochemotherapy in PLELC patients.
