Purpose: This study was aimed to analyze the contents and trend of published research in oncology nursing during the past five years in Korea and to suggest the direction for future research. Methods: Using the key words "cancer", "cancer patients", and "tumor", 391 nursing research published from 2003 to 2008 were selected for the analysis. Results: 1) Three hundred fifty-five (90.8%) of the studies used quantitative research approach, whereas most studies were descriptive in nature. 2) The main subjects of the study were cancer patients with mixed diagnosis (36.4%) and breast cancer patients (20.0%). 3) Complementary alternative therapy (28.9%), educational program (25.6%), and psycho-social and spiritual program (16.7%) were the most frequently used nursing interventions. Most frequently measured outcome variables were psycho, socio, and spiritual factors (38.8%), symptoms (28.2%) and physiological factors (14.6%). 4) Most frequently used key words were identified as quality of life, fatigue, coping, pain, anxiety, anorexia, and depression. Conclusion: The number of published research in oncology nursing in Korea has been increased. It is suggested to conduct international studies to develop, compare, and replicate nursing interventions for patients with cancer in future. Increasing funding, establishing research infrastructure, and removing methodological challenges are warranted for better research environment.
