Pathological Response After Neoadjuvant Treatment on NSCLC
- Conditions
- Stage IIIA Non-small Cell Lung Cancer
- Interventions
- Registration Number
- NCT05167487
- Lead Sponsor
- Fundación GECP
- Brief Summary
This is a non-interventional, observational, multicenter and retrospective study. Being limited to the collection of patient data already filled in the Tumor Thoracic Registry data base and the data from stage IIIA clinical trials case report forms.
- Detailed Description
This is a non-interventional, observational, multicenter and retrospective study that will not under any circumstances interfere in the physician's normal clinical practice. Being limited to the collection of patient data already filled in the Tumor Thoracic Registry (TTR) data base and the data from stage IIIA clinical trials case report forms, it does not entail any diagnostic or therapeutic procedure outside of normal clinical practice.
The primary objective is to assess pathological response after neoadjuvant treatment as a subrogate endpoint for overall survival and disease-free survival in resectable stage IIIA non-small cell lung cancer patients.
It is estimated that around 15-20 Spanish sites are enrolling patients with these characteristics in the TTR or in the stage IIIA clinical trials of the Fundación GECP.
Pathologists and physician's of these sites will be invited to participate in the PLANET study as all cases will be clinical-pathologically re-evaluated to reach the study objectives. Each pathologist will re-evaluate the specimens from the selected patients under common criteria.The sample size would be 150 patients enrolled in the study.

Cisplatin Resectable stage IIIA non-small cell lung cancer patients treated with platinum-based neoadjuvant treatment and surgery. Experimental: platinum-based neoadjuvant treatment and surgery. Carboplatin Resectable stage IIIA non-small cell lung cancer patients treated with platinum-based neoadjuvant treatment and surgery.
- Primary Outcome Measures
Name Time Method To assess pathological response after neoadjuvant treatment as a subrogate endpoint for overall survival and disease-free survival in resectable stage IIIA non-small cell lung cancer patients. From the end of neoadjuvant treatment until the last follow up or death, assessed up to 45 months Pathological response will be assessed as complete pathological response, major pathological response (defined as ≤10% of viable tumor cells) and incomplete pathological response.
- Secondary Outcome Measures
Name Time Method To describe the percentage of residual viable tumor in this population of patients under common criteria From the end of neoadjuvant treatment until the last follow up or death,assessed up to 45 months A) No response or more than 70% of viable tumor: Lymph node major pathological response negative (LN-MPR)- B) ≤70% of viable tumor cells: Lymph node major pathological response positive (LN-MPR)+ C) No evidence of any viable tumor (including primary tumor): Complete pathological response
To describe the histopathological changes within tumor bed associated to tumor response From the end of neoadjuvant treatment until the last follow up or death, assessed up to 45 months Types of histopathological changes within tumor bed: fibrosis, lymphoid aggregates and others
To describe the relation between nodal downstaging after neoadjuvant treatment and overall survival From the end of neoadjuvant treatment until the last follow up or death, assessed up to 45 months Downstaging after surgery is a reduction in the stage of a cancer. Overall Survival defined as the length of time from either the date of diagnosis or the start of the treatment that patients diagnosed with the disease are still alive.
To correlate pathological response and post-surgical complications From the end of neoadjuvant treatment until the last follow up or death, assessed up to 45 months Pathological response will be assessed as complete pathological response, major pathological response (defined as ≤10% of viable tumor cells) and incomplete pathological response.
