Local Therapy in Advanced NSCLC With Non-progressive Disease (PD) After First Line Therapy


This is a prospective single arme real-world study clinical study, which aims to investigate the overall benefit and safety of consolidative therapy in advanced NSCLC (stage III/IV) patients , who do not progress after front line systemic therapy (chemotherapy, target therapy or immunological checkpoint inhibitors).

Full Title of Study: “Local Consolidative Therapy (LCT) in Patients With Advanced Stage Non-small Cell Lung Cancer Who do Not Progress After Front Line Systemic Therapy”

Detailed Description

It is required that pathological diagnosis and genetic profile including epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK) and ROS proto-oncogene 1 (ROS1) be established prior to enrollment. Standard front line systemic should be given according to clinical practice. Molecular targeting drugs for patients with driving mutations should be acquired legally. Patients without driving mutations should undergo standard first line chemotherapy and or immunological checkpoint inhibitors. One cycle is three weeks and response evaluation is done every two cycles. CR, PR and SD should be confirmed after four cycles of therapy. Patients, who achieve non-PD after four cycles of treatment, with distant metastasis involving no more than five total metastatic lesions, will be screened and enrolled.


  • Other: local consolidative treatment
    • local consolidative treatment to primary or metastases, which includes surgery, radiotherapy or interventional therapy

Arms, Groups and Cohorts

  • Other: local consolidative treatment
    • Patients will be referred to multiple disciplinary treatment discussion for the decision of local consolidative treatment to primary or metastatic lesions including surgery, radiotherapy or interventional therapy.

(based on modified Cockcroft-Gault formula). – Adequate coagulating function. – For all females of childbearing potential a negative serum/urine pregnancy test must be obtained within 48 hours before enrollment. Postmenopausal women must have been amenorrhoeic for at least 12 months to be considered of non-childbearing potential. Males must agree to use effective contraception during the study period and for at least 12 weeks after completion of the study treatment. – Written (signed) informed Consent to participate in the study. – Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures. Exclusion Criteria:

  • Stage I-III a NSCLC completing radical treatment , then undergoing systemic anti-cancer treatment after recurrence. – Patients with PFS no more than 3 months. to first line theray. – Patients with history of any other malignancies within 5 years (except for adequately treated carcinoma in situ of the cervix or basal or squamous cell skin cancer). – Prior palliative surgery or other local therapy specifically directed against advanced lung cancer. – Contraindication for localized treatment including surgery, radiotherapy or interventional therapy judged by physicians. – Patients with any unstable systemic disease (including active infections, significant cardiovascular disease, any significant hepatic, renal or metabolic disease). – Patients who are at risk (in the investigator's opinion) of transmitting human immunodeficiency virus (HIV) through blood or other body fluids. – Nursing or lactating women. – Sexually active males and females (of childbearing potential) unwilling to practice contraception during the study. – Patients who has mental disorder or other disease that contribute to no compliance. – Unwilling to write informed consent to participate in the study. – Patients who is unwilling to accept the follow-up.
