RATIONALE: Diagnostic procedures, such as positron emission tomography and computed tomography, may help learn the extent of disease and allow doctors to plan 3-dimensional conformal radiation therapy.
PURPOSE: This phase II trial is studying the side effects of positron emission tomography and computed tomography and to see how well it works in planning treatment for patients undergoing 3-dimensional conformal radiation therapy for non-small cell lung cancer that cannot be removed by surgery.
- Prospectively evaluate the technical feasibility of integrating PET-CT scan fusion in St. Luke's Hospital in patients with unresectable, stage I-IIIB non-small cell lung cancer who underwent radical 3-D conformal radiotherapy (3-DCRT). (Pilot)
- Determine the rate of PET-CT scan based treatment delivery. (Pilot)
- Determine the safety of PET-CT scan-based radiotherapy with regard to loco-regional disease control. (Phase II)
- Compare the gross tumor volume, planning target volume, and organs at risk dose volume histogram between a conventional 3-D conformal radiotherapy (3-DCRT) plan and a PET-CT-based 3-DCRT plan.
OUTLINE: Patients undergo a non-contrast computed tomography (CT) scan followed by a fludeoxyglucose F 18 positron emission tomography/computed tomography (PET/CT) imaging scan to plan treatment volumes. Patients undergo radical 3-dimensional conformal radiotherapy using the PET-CT gross treatment volume wherever possible.
After completion of study therapy, patients are followed up every 3 months for 2 years and then every 6 months thereafter.
Primary Purpose: Diagnostic

RATIONALE: Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. PURPOSE: This phase...
Tumor hypoxia contributes to radiation resistance. A noninvasive assessment of tumor hypoxia would be valuable for prognostication and possibly selection for hypoxia-targeted therapies. F-pentafluorin...
Conventional 3-dimensional conformal radiation therapy (3DCRT) for head and neck cancer (HNC) can cause hyposalivation, leading to caries and tooth extraction-related osteoradionecrosis. Intensity-mod...
Computed tomography (CT), a strong diagnostic tool, delivers higher radiation doses than most imaging modalities. As CT use has increased rapidly, radiation protection is important, particularly among...
A cost-effectiveness analysis of IMRT compared to 3D-CRT for head and neck cancer patients (HNCPs) was conducted in the Brazilian Public Health System.
The use of computer simulation is arguably more widespread in other industries than in medicine. However, it has filtered into mainstream use in radiation therapy via a commercial product born from co...
Computed tomography modalities which use a cone or pyramid-shaped beam of radiation.
Computed tomography where there is continuous X-ray exposure to the patient while being transported in a spiral or helical pattern through the beam of irradiation. This provides improved three-dimensional contrast and spatial resolution compared to conventional computed tomography, where data is obtained and computed from individual sequential exposures.
An imaging technique using a device which combines TOMOGRAPHY, EMISSION-COMPUTED, SINGLE-PHOTON and TOMOGRAPHY, X-RAY COMPUTED in the same session.
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.
Three-dimensional computed tomographic imaging with the added dimension of time, to follow motion during imaging.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
GILOTRIF (afatinib) is a kinase inhibitor indicated for the first-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumors have epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 (L8...
