Brief Summary

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.

This is a clinical study, as the patient will be treated using the PET-CT-GTV: - The pilot study is investigating the technological feasibility - The Phase II study will be a 2-stage Phase II study

Detailed Description

Pilot Study- Primary Objectives:

* Prospective evaluation of the technical feasibility of integrating PET-CT fusion in St Luke's Hospital

* Rate of PET-CT Scan based treatment delivery

Pilot Study- Secondary Objectives:

-Comparison of GTV, PTV and OAR DVHs between conventional 3-DCRT plan and PET-CT based 3-DCRT plan.

Phase II Study- Primary Objective:

-The safety of PET-CT scan based radiotherapy, with regard to loco-regional disease control.

Phase II Study- Secondary Objectives:

-Comparison of GTV, PTV and OAR DVHs between conventional 3-DCRT plan and PET-CT based 3-DCRT plan.
