What this trial studies

This study aims to determine if the side effects experienced by patients undergoing radiation therapy for early-stage lung cancer differ based on the treatment schedule. Participants will be randomly assigned to receive either a 3 Fraction or a 5 Fraction schedule of radiation therapy. Following the completion of their treatment, patients will have follow-up appointments with their radiation oncologist to monitor any side effects and overall health outcomes.

Who should consider this trial

Good fit: Ideal candidates include patients with early-stage non-small cell lung cancer classified as AJCC stage I or II.

Not a fit: Patients with advanced lung cancer or those who do not meet the specific staging criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help optimize radiation treatment schedules to minimize side effects for lung cancer patients.

How similar studies have performed: Other studies have explored different radiation schedules, but this specific comparison of 3 vs. 5 fractions for early-stage lung cancer is relatively novel.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Histological confirmation of non-small cell cancer will not be required as primary goal of this phase II trial is to look at toxicity. However, all primary non-small cell lung cancers otherwise of following types are eligible: squamous cell carcinoma, adenocarcinoma, large cell carcinoma, bronchioalveolar cell carcinoma, or non-small cell carcinoma not otherwise specified.
* Eligible patients must have appropriate staging studies identifying them as specific subsets of AJCC stage I or II based on only one of the following combinations of TNM staging:
* T1, N0, M0
* T2 (≤ 5 cm), N0, M0
* Patients with hilar or mediastinal lymph nodes ≤ 1cm and no abnormal hilar or mediastinal uptake on PET will be considered N0. Patients with \> 1 cm hilar or mediastinal lymph nodes on CT or abnormal PET (including suspicious but non-diagnostic uptake) may still be eligible if directed tissue biopsy of all abnormally identified areas are negative for cancer. All patients with suspicious nodes will be evaluated for mediastinal and hilar staging with bronchoscopy and (if amenable) bronchoscopic biopsy (preferably navigational biopsy and/or endobronchial US guided biopsy).
* Zubrod performance status 0-2 within 4 weeks of study entry.
* Women of childbearing potential and male participants must use an effective contraceptive method.
* Evaluations required at time of study entry:
* History \& Physical by a radiation oncologist within 4 weeks of study entry;
* Vitals within 4 weeks of study entry;
* Evaluation by a thoracic surgeon (either via clinical examination and/or input at multidisciplinary tumor board) prior to study entry;
* PFTs: Routine spirometry, lung volumes, diffusion capacity, and arterial blood gases within 8 weeks prior to study entry;
* CT Chest within 6 weeks of study entry (preferably with intravenous contrast, unless medically contraindicated) - to include the entirety of both lungs, the mediastinum, liver, and adrenal glands; primary tumor dimension will be measured on this CT;
* Whole body positron emission tomography (PET) scan using FDG with adequate visualization of the primary tumor and draining lymph node basins in the hilar and mediastinal regions within 6 weeks prior to study entry.
* Informed consent signed by the subject and a member of the study team.

Exclusion Criteria:

* Patients with central tumors. Specifically; central location implies a tumor inside the zone of the proximal bronchial tree defined as a volume 2 cm in all directions around the proximal bronchial tree (carina, right and left main bronchi, right and left upper lobe bronchi, intermedius bronchus, right middle lobe bronchus, lingular bronchus, right and left lower lobe bronchi
* Evidence of regional or distant metastases after appropriate staging studies.
* Synchronous primary NSCLC.
* Those with prior malignancy in the past 2 years other than non-melanomatous skin cancer or in situ cancer or thyroid cancer.
* Previous lung or mediastinal radiotherapy.
* Plans for the patient to receive concomitant antineoplastic therapy (including standard fractionated radiotherapy, chemotherapy, biological therapy, vaccine therapy, and surgery) while on this protocol.
* Patients with active systemic, pulmonary or pericardial infection.
* Pregnant or lactating women, as treatment involves unforeseeable risks to the embryo or fetus.
