SRS/SRT/Hypo-RT Versus HA-WBRT for No More Than 10 Brain Metastases in SCLC

Recruiting now · Phase 3

Conditions studied: Small-cell Lung Cancer, Brain Metastases, SRS, Stereotactic Radiotherapy, Whole Brain Radiotherpay, Hippocampal-avoidance

In brief

This phase III trial compares the effect of stereotactic radiosurgery and whole brain radiation therapy that avoids the hippocampus (the memory zone of the brain) for the treatment of small cell lung cancer that has spread to the brain.

Investigators should consider these factors when selecting patients for this trial. Investigators also should consider all other relevant factors (medical and non-medical), as well as the risks and benefits of the study therapy, when deciding if a patient is an appropriate candidate for this trial.
Adult patients (18-80 years of age) with Eastern Cooperative Oncology Group performance status 0-2 or Karnofsky performance score ≥ 70, expected life time more than 6 months;
Pathologically (histologically or cytologically) proven diagnosis of small cell lung cancer within 5 years of registration. If the original histologic proof of malignancy is greater than 5 years, then pathological (i.e., more recent) confirmation is required (e.g., from a systemic or brain metastasis). Patients with de novo or recurrent small cell lung cancer are permitted;
No more than 10 metastatic brain lesions with ≤5 cm in largest diameter and ≤150 ml in treated volume, confirmed by a high-resolution (thickness ≤2mm) , 3-dimensional T1-weighted postgadolinium magnetic resonance imaging (MRI) brain scan within 2 weeks of study initiation. All brain metastases must be outside a 5-mm margin around either hippocampus or optic pathways.
Not all metastatic brain lesions are recommended or suitable for surgical resection after multidisciplinary team discussion. If part of metastatic brain lesions are resected, the patient is permitted for enrollment evaluation at least two weeks after resection; 5 Patients must have the psychological ability and general health that permits completion of the study requirements, all assessment (HVLT-R, MoCA, EORTC QLQ-C30) and required follow up (at least 6 months);
At least one measurable BM according to the Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) criteria; 7. Women of childbearing potential and men who are sexually active should be willing and able to use medically acceptable forms of contraception during treatment on this study and for up to 180 days after completion of all treatment to prevent pregnancy or fathering a child; 8. Written informed consent (must be available before enrolment in the trial).

You may not qualify if…

Clinical or radiologic evidence of new, untreated, and/or progressive brain metastases prior to registration;
Previous radiotherapy of the brain;
Patients can not tolerate immobilization or are with MRI contraindication (i.e., cardiac pacemaker, implanted defibrillator, certain cardiac valve replacements, certain metal implants);
Radiographic evidence of hydrocephalus or other architectural distortion of the ventricular system, leptomeningeal metastases, increased intracranial pressure requiring immediate depression surgery.
Patients who have not yet recovered from acute high-grade (≥Grade 3) toxicities of prior therapies according Common Terminology Criteria for Adverse EventsVersion5.0 (CTC 5.0);
Presence of other serious illnesses such as acute myocardial infarction, severe arrhythmia, or psychiatric disorders within the past 6 months;
Known carcinoma < 5 years ago (excluding carcinoma in situ of the cervix, basal cell carcinoma, squamous cell carcinoma of the skin) requiring immediate treatment interfering with study therapy;
Pregnant or lactating women;
Participation in another clinical study or observation period of competing trials, respectively;
