Study Overview
Brief Summary
OBSTINATE is an observational, national, prospective, multicentric study on Quality of life in patients with unresecable stade III non-small cell lung cancers.
Locally advanced non-small cell lung cancers (NSCLCs with a Tumor, Node and Metastasis [TNM] stage III) patients represent approximately a third of newly discovered NSCLCs every year, and a very heterogeneous group of clinical situations. Therapies are multidisciplinary and very heterogeneous across oncology centers. Patients with locally advanced NSCLC have a high symptom burden that is known to affect their quality of life. Health-related quality of life (HR-QoL) is a specific and multidimensional type of patient-reported outcome (PRO) related to the physical, psychological and social impact of the disease and its treatment as perceived by patients. HR-QoL allows, together with data of efficacy and safety, a more complete assessment of risks and benefits of each treatment. Therefore, QoL maintenance is a valuable consideration for treatment decisions, especially in the rapidly evolving therapeutic landscape of unresectable NSCLC.
The study is designed to collect PROs HR-QoL data from every new patient diagnosed with an unresectable stage III NSCLC over a period of 18 months. We also aim to describe clinical characteristics of these patients, the therapeutic strategies conducted, and outcomes in a "real-word" oncological practice.
Detailed Description
OBSTINATE is an observational, prospective, national, multicentric study conducted in patients newly diagnosed with an unresectable stage III NSCLC (with exclusion of early stages NSCLC classified to pathological stage III).
OBSTINATE is a study planned to include 450 patients between 50 to 70 GFPC-affiliates or GFPC-associated centers approximately. All centers are located in France. The participating Site Investigators will be treating physicians within one of the participating centers.
After screening for eligibility checks, patients will receive the Patient Information Note from the Site Investigators. This Patient information Note will describe the study purpose and modalities. Patients who meet the eligibility criteria and do not oppose to data collection will be enrolled. The schedule of the medical visits in the study center will depend on the patient and his/her routine clinical care Protocol-relevant data will be collected by the treating physician within each center, for up to 5 years following the last patient's enrollment in the study.
Patients included in the study will complete the self-assess questionnaires at enrollment and during routine care follow-up, according to pre-specified data collection schedule.
Usual practices or modalities of follow-up of patients will remain unchanged compared to the current clinical practice as the study is designed to provide descriptive summary information.

Inclusion Criteria
- •Pathological confirmation of NSCLC obtained from a tumor cytology or biopsy
- •Treatment-naïve unresectable TNM stage III NSCLC (according to the 8th TNM IASLC edition). Of note, unresectability could be due to either functional limitation or anatomical extension of the tumor.
- •Patient willing and able to complete collection of data via self-assessment questionnaires
- •Patient without any local or systemic anti-neoplastic treatment are eligible (palliative symptomatic radiotherapy is considered best supportive care)
- •Patients participating in other interventional or non-interventional studies can be included.
Exclusion Criteria
- •Early stage NSCLC initially treated locally (surgery or other) and classified as pathological TNM stage III (according to the 8th TNM IASLC edition)
- •At the treating physician's discretion, patient not eligible physically or psychologically to be included in a clinical trial
- •Inability to read and/or fill out self-assessment questionnaires
- •Patient unable to express opposition to data collection
Outcomes
Primary Outcomes
QLQ-LC13 (defined as the outcomes of a clinical intervention obtained by the patient)
Time Frame: Up to 6,5 years (18 months of recruitment + 5 years). For Cohort 1 & 2, a follow-up post progression is planned
Change in patient's QLQ-LC13 during treatment and follow-up until confirmed progression, loss of follow-up or end of the study compared to Baseline in patients diagnosed with unresectable stage III NSCLC in a "real-world" oncological practice. This evaluation is based on self-assess questionnaire distributed to the patients according to pre-specified data collection schedule. The primary objective will be addressed in the cohort as a whole, and independently for every cohort of interest.
EQ5D-5L (defined as the outcomes of a clinical intervention obtained by the patient)
Time Frame: Up to 6,5 years (18 months of recruitment + 5 years). For Cohort 1 & 2, a follow-up post progression is planned
Change in patient's EQ5D-5L during treatment and follow-up until confirmed progression, loss of follow-up or end of the study compared to Baseline in patients diagnosed with unresectable stage III NSCLC in a "real-world" oncological practice. This evaluation is based on self-assess questionnaire distributed to the patients according to pre-specified data collection schedule. The primary objective will be addressed in the cohort as a whole, and independently for every cohort of interest.
QLQ-C30 (defined as the outcomes of a clinical intervention obtained by the patient)
Time Frame: Up to 6,5 years (18 months of recruitment + 5 years). For Cohort 1 & 2, a follow-up post progression is planned
Change in patient's QLQ-C30 during treatment and follow-up until confirmed progression, loss of follow-up or end of the study compared to Baseline in patients diagnosed with unresectable stage III NSCLC in a "real-world" oncological practice. This evaluation is based on self-assess questionnaire distributed to the patients according to pre-specified data collection schedule. The primary objective will be addressed in the cohort as a whole, and independently for every cohort of interest.
Secondary Outcomes
