Intensive chemotherapy programme in children with cancer may result in psychological mal adjustment. Treatment facilities as well as psychological support are of great importance to minimize these side effects. In 1998 the programme of psychological support was introduced in 7 Polish paediatric haematology / oncology centres. Psychological adjustment of patients treated in each centre was examined 5 yrs after the termination of therapy. At the same time children with new diagnosis of cancer were monitored psychologically along with the psychological support programme. Psychological status of each patient was examined with the following tests: Cattell's questionnaires (CPQ, HSPQ), Manifest Anxiety Scale, Spielberger's inventories (STAI, STAIC), Wechsler Intelligence Scale. The programme of psychological support was based on guidelines of SIOP Psychosocial Committee and included such elements as informing about diagnosis and treatment, explaining any doubt, maintaining an open communication, educational care in the periods of treatment, encouraging to activity even during periods of discomfort. The analysis showed that most of the participating centres could only provide some elements of the support programme. The main problem was to convince medical staff to inform children on diagnosis and treatment plans. Preliminary results of the study indicate that full psychological support for children with cancer and their families from the beginning of therapy can result in improvement in psychological adjustment. During the ensuing period, patients and their parents appreciate the possibilities to contact a psychologist.
