Which role plays specialized palliative care in patients with relapsed and/or metastatic head and neck cancer? A retrospective analysis in Southern Switzerland.

e17503 Background: early palliative care (PC) for patients with advanced cancer improves quality of life, promotes home deaths and can improve survival. Limited data are available regarding PC in advanced head and neck cancer (HNC) patients. To investigate the effect of introducing specialized PC in patients with relapsed and/or metastatic head and neck cancer. Methods: between October 2010 and December 2018, the medical charts of all patients treated in the Oncology Institute of Southern Switzerland with relapsed and/or metastatic HNC were reviewed. Site, status of disease (metastatic at diagnosis, locally or metastatic relapsed), type and lines of treatment, treatment response and referral to specialist palliative care (yes or no) were documented. Comparisons were made between patients referred and non-referred to PC. Results: sixty-two patients with relapsed/metastatic HNC were identified, 32 (51.6%) of which were referred to specialized PC. Patients were mainly men (47, 75.8%), with a median age of 66 years (range 43 – 86). Forty-two patients (67.7%) had a metastatic disease and the most common site of tumor was the oropharynx (35.5%), followed by oral cavity (32.3%), larynx (16.1%), hypopharynx (12.9%), and unknown primary (3.2%). Forty-eight patients (77.4%) were treated with systemic treatment (75% in the PC group and 80% in the non-PC group, p = 0.638). The median overall survival was 8.1 months for all patients, 8 months for the PC group and 8.7 months for the non-PC group, without significant difference (p = 0.440). Of the deceased patients, 70% of the PC group and 73.3% of the non-PC group received chemotherapy in the last three months of life. A greater percentage of patients in the PC group died at home, but without significant difference (39.2% vs. 19%, p = 0.134). Conclusions: only half of the patient had access to specialized PC. Whereas it did not seem to affect overall survival nor influence chemotherapy prescription, it seemed to favor home deaths. Further studies investigating the impact of early PC in recurrent and/or metastatic HNC are needed to improve access to PC and maximize benefits.
