PURPOSE: This study was undertaken to evaluate the association of individual parameters and outcome in patients with unresectable locally advanced head and neck cancer treated with radiochemotherapy. MATERIALS AND METHODS: We retrospectively reviewed data from 126 patients treated in our Institution between 1998 and 2010 for a locally advanced head and neck cancer. Sixteen individual parameters were evaluated for association with specific outcomes such as overall survival, persistence of disease, disease-specific survival and disease-free survival. RESULTS: Six factors influenced overall survival on Kaplan-Meier survival analysis and on univariate Cox regression analysis: smoking, body mass index, site, haemoglobin (Hb) nadir, total dose of radiotherapy and comorbidities. On a multivariate logistic model with stepwise selection, comorbidities, body mass index, total dose and site maintained significance. A significant association for persistence of disease was found with smoking, Hb nadir and site of cancer on univariate and multivariate analysis. Disease-free survival was correlated with performance status, Hb nadir and comorbidities using Kaplan-Meier survival analysis and on univariate Cox regression analysis. Only performance status maintained the significance on multivariate analysis. Disease-specific survival was correlated with five parameters: body mass index, site, Hb nadir, therapy interruption and total dose; on multivariate analysis, Hb nadir, therapy interruption and site maintained a statistically significant association. CONCLUSIONS: Hb nadir during treatment, body mass index, smoking, stage, comorbidities and performance status are prognostic factors of outcome and response to radical treatment with radiochemotherapy.

PURPOSE: This study was undertaken to evaluate the association of individual parameters and outcome in patients with unresectable locally advanced head and neck cancer treated with radiochemotherapy. MATERIALS AND METHODS: We retrospectively reviewed data from 126 patients treated in our Institution between 1998 and 2010 for a locally advanced head and neck cancer. Sixteen individual parameters were evaluated for association with specific outcomes such as overall survival, persistence of disease, disease-specific survival and disease-free survival. RESULTS: Six factors influenced overall survival on Kaplan-Meier survival analysis and on univariate Cox regression analysis: smoking, body mass index, site, haemoglobin (Hb) nadir, total dose of radiotherapy and comorbidities. On a multivariate logistic model with stepwise selection, comorbidities, body mass index, total dose and site maintained significance. A significant association for persistence of disease was found with smoking, Hb nadir and site of cancer on univariate and multivariate analysis. Disease-free survival was correlated with performance status, Hb nadir and comorbidities using Kaplan-Meier survival analysis and on univariate Cox regression analysis. Only performance status maintained the significance on multivariate analysis. Disease-specific survival was correlated with five parameters: body mass index, site, Hb nadir, therapy interruption and total dose; on multivariate analysis, Hb nadir, therapy interruption and site maintained a statistically significant association.
