摘要

Purpose: The study aimed to analyse causes of death and differential survival after multimodal treatment of head and neck carcinoma patients. Methods and Materials: Between September 2000 and December 2015, 935 patients received a multimodal treatment of head and neck carcinoma. Of these, 562 patients (60.1%) underwent a resection of the primary tumour and a postoperative radio- or radiochemotherapy and 373 patients (39.9%) received definitive radio- or radiochemotherapy. The median follow-up was 21.0 months (0.5 - 175.4 months). Results: At the endpoint of the investigation, 465 patients (49.7%) were alive. The median survival of all patients was 44.8 months (0.5 - 164.3 months). A total of 470 patients (50.3%) died. The causes of death were divided into five groups: 22 patients (2.4%) died of therapy-associated complications with a median of 2.2 months (1.6 - 3.3 months). The 160 patients (17.1%) with intercurrent death, 117 patients (12.5%) with deaths from locoregional progression with or without metastasis, and 86 patients (9.2%) with deaths from metastasis without locoregional recurrence showed comparable survival curves with a median survival of 13.3 months, 13.6 months, and 14.4 months. Eighty-five patients (9.1%) died from second malignant diseases and controlled treated head and neck carcinomas with a median survival of 34.5 months (P < 0.001). Conclusion: Despite a locoregional control and metastasis-free survival of 78.3% patients, only 49.7% of the patients were alive, due to a high rate of intercurrent and second malignant diseases. The short median survival rate is mainly due to the tumours (locoregional and or distant progression) and intercurrent causes of death, with the second malignant diseases leading to death later on.
