[Thermoplastic mask in radiotherapy: a source of anxiety for the patient?].

PURPOSE

The thermoplastic mask often used to immobilize patients in radiotherapy can cause varying levels of stress and anxiety. This study aimed at evaluating the anxiety related to the use of radiotherapy masks and the coping strategies adopted by patients.

PATIENTS AND METHODS

Nineteen patients treated with radiotherapy mask for head and neck cancer, a brain tumour or a lymphoma, were met twice by a psychologist, either after the making of the mask and the first course of radiotherapy, or in the middle and at the end of treatment. Thirty-four semi-structured interviews were treated using a thematic content analysis and 13 patients answered to anxiety (STAI-YB) and coping (WCC) scales.

RESULTS

The STAI-YB anxiety scores related to wearing the masks were low during the radiotherapy treatment period, and were confirmed by the remarks of patients recorded during the semi-structured interviews. Most patients had a positive perception of the mask, and considered it as a friend or protection. Twelve out of the 13 patients admitting to anxiety benefited from problem focused coping strategies.

CONCLUSIONS

Thermoplastic mask-related anxiety is low and possibly lies in the positive representation patients have about the mask. The explanations provided by health professionals on the radiotherapy mask possibly have a very positive effect on this perception.
