Lung cancer practice guidelines: lessons learned and issues addressed by the Ontario Lung Cancer Disease Site Group.

PURPOSE

The primary objective was to identify the lessons learned and issues addressed by the Disease Site Group (DSG) developing guidelines on lung cancer for practitioners in the province of Ontario.

METHODS

The minutes of the Ontario Lung Cancer Disease Site Group (LCDSG) and the meeting notes of a medical sociologist who attended all LCDSG meetings were reviewed to identify the disease-specific and generic issues addressed by the LCDSG during guideline development.

RESULTS AND CONCLUSION

The Ontario LCDSG has completed three practice guidelines and has five evidence-based recommendations (EBRs) in production. Topics for guideline development were selected on the basis of known practice variability (eg, advanced-stage non-small-cell lung cancer [NSCLC]); the size of the patient population that could potentially be affected by the guideline; results of phase II trials of new and potentially expensive agents (vinorelbine, paclitaxel, and docetaxel); and randomized controlled clinical trials that support new practice standards (combined modality therapy for unresectable stage III NSCLC). The wording of each EBR reflects the strength and quality of the evidence in support of the treatment option, the primary outcome(s), and the individual physician and discipline values concerning treatment outcomes in the absence of known patient values.
