This study compared two neoadjuvant chemotherapy protocols for stage III non-small cell lung cancer (NSCLC). Protocol 2 showed a significant downstaging effect, suggesting more intensive treatment may improve outcomes in trimodal therapy.
Area of Science:
- Thoracic Oncology
- Surgical Oncology
- Medical Oncology
Background:
- Neoadjuvant chemotherapy intensification in stage III non-small cell lung cancer (NSCLC) has been explored in trimodal settings.
- Direct comparisons of intensified protocols are limited by varying selection criteria and institutional experience.
Purpose of the Study:
- To compare the efficacy of two distinct neoadjuvant chemotherapy protocols in a trimodal setting for stage III NSCLC.
- To evaluate survival, recurrence rates, and downstaging effects between the protocols.
Main Methods:
- Single-center retrospective study involving 159 patients with stage III NSCLC.
- Analysis of survival, recurrence, and tumor downstaging (ypTNM) following two different neoadjuvant protocols.
- Statistical analysis using Log-rank test and Cox regression.
Main Results:
- Overall median survival was 32 months; Protocol 1: 26 months, Protocol 2: 35 months.
- Protocol 2 demonstrated a significant downstaging effect on N-stage and overall UICC stage.
- pN-stage and ypUICC-stage were significant predictors of survival.
Conclusions:
- An intensified neoadjuvant protocol (Protocol 2) showed a trend towards improved survival and a significant downstaging benefit in stage III NSCLC.
- Achieving R0 resection with Protocol 2 is associated with better downstaging outcomes.
- Dose intensity in neoadjuvant therapy appears crucial for improving treatment efficacy in trimodal settings.
