“Sociability” is defined as the range of experiences linking the subject to others. This is the first study to focus specifically on the impact of head and neck cancer on the sociability of patients’ partners.

Data were collected via a dedicated questionnaire sent to patients’ partners. The main endpoint was partner's self-assessment of the impact of the patient's disease on the partner's everyday life. The impact on sociability was analyzed with respect to: the circle of friends (friendship environment), unknown environment, known outside environment, necessary environment, and solitary activities.

Two hundred and seventy partners responded. Their everyday activities were impacted by the patient's disease in 71.5% of cases. The friendship environment was badly affected in 46.4% of cases. The unknown environment was affected in 44.0% of cases. Social practices related to the known outside environment were affected in 67.8% of cases, and the necessary environment in 26.0%; the number of solitary activities increased in 35.6% of cases. Social impact on patients’ partners was thus considerable.
