This document summarizes information about radiotherapy for non-small cell lung cancer (NSCLC). It discusses the role of radiotherapy for early, locally advanced, and metastatic NSCLC. It describes stereotactic body radiotherapy (SBRT) for early-stage disease and concurrent chemoradiotherapy (CTRT) for locally advanced stages. It also reviews evidence on optimal radiotherapy techniques and dosing, as well as trials investigating induction, consolidation, and adjuvant chemotherapy combined with radiotherapy.

In the interest of time I could not detail all trial that have established the role of CT and RT in locally advanced NSCLC The findings from these trials are summarised on this slide NSCLCCG BMJ 1995-The meta-analysis did not provide an answer to the question of the optimal radiotherapy or chemotherapy regimen.

Terminated early on the basis of futility after an interim analysis febrile neutropenia (10.9%) and pneumonitis (9.6%); 28.8% of patients were hospitalized during docetaxel ( v 8.1% in observation arm), and 5.5% died as a result of docetaxel.
In this unselected population, gefitinib did not improve survival. Decreased survival was a result of tumor progression and not gefitinib toxicity.
Ongoing Dutch trial
below the age of 75 (patients above 75 have not been included in clinical trials), Currently, there is no consensus on the optimal chemotherapy regimen when combined with radiotherapy. There is clinical trial data to support the combination of cisplatin based chemotherapy. A number of regimens have been reported showing acceptable outcome and toxicity profiles. (EL: Refs 264-267 268-271) The choice of chemotherapy regimen with concurrent thoracic radiotherapy should be considered based on individual patient characteristics, toxicity profile and local experience

Addition of targeted agents With RT or CTRT? Consolidation treatment? Dissapointing in Swog
Update Cochrane Review 2005 (10 studies) adding the Trodella study in stage I NSCLC 2-year Survival: 58% 2-year Survival: 52% ‘ Thoracic RT is deleterious for pN0 and pN1 pts due to an excess of treatment-related toxicity in the PORT group’ ‘ Role of PORT in N2 tumours less clear and may warrant further research with newer techniques’
