Overview
This clinical trial studies side effects and best treatment time of cryodevitalization in treating patients with early stage (stage I or stage II) lung cancer. Cryodevitalization is a type of cryosurgery that uses a flexible probe (cryoprobe) to kill tumor cells by freezing them. It is delivered at the time of standard diagnostic robotic bronchoscopy. Using cryodevitalization may be safe, tolerable and/or effective in treating patients with early stage lung cancer.
Description
PRIMARY OBJECTIVE:
I. To identify the maximum tolerated dose (MTD) for cryodevitalization cycle duration.
OUTLINE: This is a dose-escalation study.
Patients undergo 3 freeze-thaw cycles of cryodevitalization over 30 seconds or 3, 5, or 7 minutes each during standard of care robotic bronchoscopy with biopsy on study. Patients then undergo standard of care surgical resection on study. Patients also undergo a chest radiography (x-ray) on study as well as computed tomography (CT) and tissue sample collection throughout the study.
After completion of study treatment, patients are followed up at 3 and 7 days and are then followed as clinically required per standard of care for 24 months.
Eligibility
Inclusion Criteria:
- Patients with a single pulmonary nodule with a size less than or equal to three centimeters (average long and short axis) confirmed as malignant intraprocedurally (rapid on-site evaluation with pathology assessment showing lung cancer or oligometastatic disease) without evidence of mediastinal involvement who require nodule biopsy prior to proceeding with surgical resection
- Nodules must be located in the outer 2/3 of the periphery of the lung, greater than 10 mm from the pleura and from large blood vessels or mediastinal structures to avoid injury to other visceral organs
- Patients deemed to have a surgical resection treatment option based on preoperative staging computed tomographic (CT), postoperative predicted forced expiratory volume in 1 second (FEV1) \> 40% and evaluation of medical comorbidities after discussion at multidisciplinary tumor board
- Age \> 18 years old
Exclusion Criteria:
- Target nodule is within the International Association for the Study of Lung Cancer (IASLC) "central zone" (including bronchial tree, major vessels, heart, esophagus, spinal cord and phrenic \& laryngeal nerves), or are \< 10 mm from the pleura
- Patients with an expected survival less than 6 months
- Patients with endobronchial lesions, concerning for malignancy, visualized during the initial bronchoscopic evaluation of the airways
- Patients with medically uncorrectable coagulopathy: abnormal platelet count \< 100 × 10\^9/L or an international normalized ratio \> 1.5
- Patients with known pulmonary hypertension (PASP \[pulmonary artery systolic pressure\] \> 50mmHg)
- Patients who are currently prescribed anticoagulants, clopidogrel, or other platelet aggregation inhibitors
- Patients with medical comorbidities deemed high-risk for surgical resection
- Pregnant women
- Inability to provide informed consent
