A Non-interventional Retrospective Study on Overall Survival in Completely Resected Chinese NSCLC Patients With Adenocarcinoma Histology- ICAN Extension Study

• Conditions: Overall Survival

• Registration Number: NCT03658928
• Lead Sponsor: Guangdong Association of Clinical Trials

Brief Summary

ICAN was a non-interventional study to explore the EGFR gene mutation status, clinical outcome and recurrent risk factors in early stage Chinese NSCLC with adenocarcinoma histology after complete resection (NIS-OCN-DUM-2009/1). The study had enrolled 571 patients from Apr. 2010 to Dec. 2010 in 24 sites located in the mainland of China. The study had completed and major results showed that EGFR mutation rate was 55.1% and 3-year DFS rate was 61.7% in early stage Chinese NSCLC with adenocarcinoma histology after complete resection. Postoperative pathologic stage, gender, surgical and resection types had a statistically significant association with 3-year DFS.

This study is ICAN extension study with the purpose to collect the overall survival data from previous ICAN study. Approximately 571 patients who participated in ICAN study will be enrolled.

Detailed Description

Primary objective

* To observe the overall survival of early stage NSCLC with adenocarcinoma histology after complete resection that had enrolled in I CAN study.

Secondary objectives

* To observe the updated DFS of early stage NSCLC with adenocarcinoma histology after complete resection that had enrolled in I CAN study;

* To observe the treatment pattern after tumor recurrence of early stage NSCLC with adenocarcinoma histology after complete resection that had enrolled in I CAN study in real-world setting;

* To explore the risk factors of OS for early stage NSCLC with adenocarcinoma histology after complete resection that had enrolled in I CAN study in real-world setting, such as EGFR mutation status, gender, smoking history, treatment pattern after recurrence, etc.

Primary Outcome Measures

Name	Time	Method
Overall survival	from the date of operation to date of death from any cause, whichever came first, assessed up to 8 years.	is defined as the time from the date of operation to date of death. For patients who are still alive, the last date when the patient is known to be alive will be used to determine the censoring date.

Secondary Outcome Measures

Name	Time	Method
Disease free survival	•from operation until recurrence of tumor or death from any cause, whichever came first, assessed up to 8 years.	is defined as the time from operation until recurrence of tumor or death from any cause, whichever occurs first.
