Historically, long-term survival rates in locally advanced non-small-cell lung cancer (NSCLC) have been disappointingly low, and treatment toxicities have been significant.To assess survival outcomes, treatment toxicities, patterns of disease recurrence and prognostic variables for patients with locally advanced NSCLC treated with concurrent chemoradiation.Patients who completed treatment with chemotherapy and simultaneous chest irradiation for locally advanced NSCLC at the Royal Prince Alfred Hospital (Sydney, Australia) in the period January 1994 to July 2009 were identified. We retrospectively reviewed the patients' medical records to obtain patient demographic data, clinical data, information on tumour characteristics and treatment administered, and outcome data such as survival, treatment toxicities and tumour recurrence patterns.Our patient cohort consisted largely of urban-dwelling male smokers with good baseline performance status. As of December 2012, 93/105 patients had died. Median overall and progression-free survival was 20 months and 11 months respectively. The 5-year survival rate was 17%. Eight patients had survived longer than 8 years, and 13 patients enjoyed progression-free survival longer than 3 years. Locoregional tumour recurrence occurred most frequently, followed by brain and bone metastases. Adverse effects from chemoradiation included varying degrees of gastrointestinal, pulmonary and haematological toxicity. Three deaths occurred from radiation-induced pneumonitis. Weight loss at presentation was statistically significantly associated with worse overall survival in univariate analyses (P = 0.01).Our survival results are consistent with the recent international literature and indicate that a proportion of patients with locally advanced NSCLC can enjoy prolonged survival following treatment with concurrent chemoradiation. |
