Abstract
Background: Medical care provided to adolescents with lymphatic system cancer and leukemia should take into consideration psychological aspects, due to the increased risk of anxiety disorders, depression, irritability and sleep disorders, which may determine acceptance of the disease. Methods: The study included 50 patients of both sexes, aged 14-17. The following questionnaires were used: The Hospital Anxiety and Depression Scale (HADS-M), Athens Insomnia Scale (AIS), Acceptance of Illness Scale (AIS) and Numeric Rating Scale (NRS). Results: A significant group of patients did not accept their disease. Male gender turned out to be a predictor of higher acceptance of the disease. The dominant emotion among young people was anxiety, especially among girls (p = 0.012). The level of depression of most respondents was low or moderate (p = 0.143), and irritability was high (p = 0.074), regardless of gender. Sleep disorders were more common in girls (p < 0.001) and were associated with high levels of anxiety and depression. Regardless of gender, most adolescents experienced pain (≥3 NRS). Conclusions: Recognizing the predictors of disease acceptance, especially in the initial stage of treatment, may be of key importance for current and further therapeutic effects in adolescents; therefore, it should be included in the standards of care for this group of patients.
