PURPOSE: Phase I trial to study the effectiveness of gene therapy plus radiation therapy in treating patients who have non-small cell lung cancer.
- Determine the feasibility and tolerability of adenovirus p53 gene therapy and radiotherapy in patients with non-small cell lung cancer with or without prior radiotherapy to the indicator lesion(s).
- Determine p53 and p21 expression and induction of apoptosis and necrosis in patients treated with this regimen.
- Assess any vector incorporation, antitumor response, local control, viral dissemination, and development of adenovirus antibodies in patients treated with this regimen.
OUTLINE: This is a multicenter study. Patients are stratified by prior radiotherapy to the indicator lesion(s) (yes vs no).
Adenovirus p53 is injected directly into an endobronchial lesion via bronchoscopy or into locoregional tumors via multiple percutaneous punctures under fluoroscopic, ultrasonic, or CT scan guidance on days 1, 3, and 8. Patients undergo radiotherapy beginning on day 2 and continuing for a total of 10 days.
Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.
PROJECTED ACCRUAL: A total of 10 patients will be accrued for this study within 1 year.
Primary Purpose: Treatment
Ad5CMV-p53 gene, radiation therapy

Stereotactic body radiation therapy (SBRT) has become standard of care for inoperable early stage non-small cell lung cancer and is often used for recurrent lung cancer and pulmonary metastases. Radia...
Small cell lung cancer (SCLC) is a very aggressive form of lung cancer. SCLC treatment requires multidisciplinary management and timely treatment. Radiation therapy is an important part of management ...
Radiation therapy might modify the cancer immune environment to enhance the antitumor effect of immune checkpoint inhibitors. We performed a feasibility study of nivolumab following stereotactic radia...
In patients with non-small cell lung cancer (NSCLC) who undergo trimodality therapy (chemoradiation followed by surgical resection), it is unknown whether limiting preoperative radiation dose to the u...
To date, no published randomized trials have shown stereotactic body radiation therapy (SBRT) to offer superior outcomes to conventionally fractionated radiation therapy (CFRT) for early-stage non-sma...
Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.
Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
Nuclear phosphoprotein encoded by the p53 gene (GENES, P53) whose normal function is to control CELL PROLIFERATION and APOPTOSIS. A mutant or absent p53 protein has been found in LEUKEMIA; OSTEOSARCOMA; LUNG CANCER; and COLORECTAL CANCER.
Organs which might be damaged during exposure to a toxin or to some form of therapy. It most frequently refers to healthy organs located in the radiation field during radiation therapy.
Drugs used to protect against ionizing radiation. They are usually of interest for use in radiation therapy but have been considered for other, e.g. military, purposes.
