Résumé
AIMS: To understand management strategies and outcomes of patients diagnosed with a head and neck tumour and a synchronous second cancer developed at another anatomic site. MATERIALS AND METHODS: Retrospective analysis of all patients diagnosed with a head and neck carcinoma and a synchronous cancer and engaged in curative-intent treatments. To evaluate therapeutic strategies, each patient's treatment process was divided into sequential therapeutic modalities and corresponding targets (head and neck and/or synchronous tumour) were identified. Patient outcome was analysed with an intent-to-treat approach. RESULTS: Forty-three patients were entered into the study (mean age=57.4 years). Synchronous tumours concerned the lung (57.8%), oesophagus (31.1%) or other sites (11.1%). Treatments were complex, including one to four consecutive modalities, with a mean duration of 4.6 months. When both tumours were advanced, treatments were frequently initiated with dual-spectrum chemotherapy (66.7%). In other situations, a locoregional treatment was often (81.1%) proposed immediately. When both tumours were in early stages, this initial locoregional treatment could be extended to target both tumours together (30.0%). For patients whose tumours differed in severity, this locoregional treatment targeted only one tumour (85%); priority was given to the most advanced one (76.5%). Nine patients had definitive treatment interruption. Associated risk factors were a low body mass index (P=0.03) and advanced-stage tumours (P=0.01). Thirty-one patients died (72.1%) with a median time to death of 7.7 months. The median follow-up for survivors was 46.2 months. Three-year overall survival was 33.9%. Low body mass index (P=0.001), advanced-stage synchronous tumours (P=0.03) and oesophageal primaries (P=0.03) altered the overall survival. Three-year locoregional and metastatic progression-free survival was 40.8 and 62.5%, respectively. Low body mass index (P=0.01) and advanced-stage synchronous tumours (P=0.01) increased the risk of disease failure. CONCLUSIONS: Head and neck tumours diagnosed with a synchronous cancer are a complex challenge. Despite a severe prognosis, patients who are not underweight, presenting with lower-stage tumours (especially the synchronous tumour) and without oesophageal involvement could most benefit from aggressive treatments.
