Real-world Treatment Patterns and Associated Outcomes in Patients With Resectable Early-stage Non-small Cell Lung Cancer

Study Overview
=================
Brief Summary
-----------------
This is a non-interventional, multi-country, multicentre, retrospective study designed to determine the treatment patterns and associated survival rate in patients with primary stage IA to IIIB resectable NSCLC diagnosed between 01 January 2013 and 31 December 2017 and followed until at least 31 December 2020 The main objective of this study is to describe the treatment patterns and determine their associated 3-year survival rate according to clinical and pathologic staging in patients with resectable early-stage (IA to IIIB as per AJCC seventh edition) NSCLC.

Detailed Description
-----------------
This is a non-interventional, multi-country, multicentre, retrospective study designed to determine the treatment patterns and associated survival rate in patients with primary stage IA to IIIB resectable NSCLC diagnosed between 01 January 2013 and 31 December 2017 and followed until at least 31 December 2020. This study will also determine the prevalence of EGFR mutations and PD-L1 expression, and the clinical outcomes as per the treatment patterns and clinico-pathological staging. Data will be collected retrospectively from the patients' medical records from the date of initial diagnosis of early-stage NSCLC (index date) to the end of follow up ie, until death, the last medical record entry, or date of data extraction, whichever is the earliest. The data on treatment modalities, sociodemographic, clinico-pathological characteristics, and exposure and outcome variables (ie, medical and treatment history, disease staging, biomarker assessments, radiological findings, concomitant medications, survival), factor(s) for prescribing neo-adjuvant and/or adjuvant treatment and reason(s) for discontinuation will be extracted from patients' medical records.

Eligibility Criteria
-----------------
Inclusion Criteria: Adult female and male patients aged ≥18 years or 'adults' according to age of majority as defined by the local regulations on index date Patient or next of kin/legal representative (for deceased patients at study entry, unless a waiver is granted) willing and able to provide written or electronic informed consent according to the local regulations, where applicable Patients diagnosed with primary stage IA to IIIB NSCLC as per seventh edition AJCC whose tumour was deemed resectable between 01 January 2013 and 31 December 2017 and followed up until at least 31 December 2020, as per the medical records with availability of at least 12 months of follow-up data from the index date (date of diagnosis of early-stage [IA to stage IIIB] resectable NSCLC), unless patient died within 12 months of diagnosis. Exclusion Criteria: Patients with a concomitant cancer at the time of diagnosis of NSCLC, except for nonmetastatic nonmelanoma skin cancers, or in situ or benign neoplasms; a cancer will be considered concomitant if it occurs within 5 years of NSCLC diagnosis Patients diagnosed with stage IV NSCLC Histology of the tumour is small cell lung cancer, neuroendocrine in origin, or a mixed histologic type with small cell and non-small cell lung cancers.
