Symptoms in adults with lung cancer. A systematic research review.

Health care providers play a key role in providing adequate symptom management and promoting quality of life during chronic illness. Several studies have noted that adults with lung cancer experience more symptom distress than patients with other types of cancer. Therefore, symptom management in this group of patients is particularly important. An understanding of the research conducted in this area is important for further knowledge development and for potentially improving symptom management. This paper presents a systematic review of empirical studies examining symptoms in adults with lung cancer. The results of this systematic review revealed that although major strides have been made in understanding symptoms associated with lung cancer, further progress is needed to decrease the morbidity associated with uncontrolled symptoms. Theoretical, conceptual, and/or methodological issues identified through this review must be addressed in future research. In particular, the researcher should provide information about the theoretical or empirical framework guiding the study, give an explicit definition about the dimensions of the symptom experience being studied, report refusal rates and attrition, and use instruments that are reliable and valid.
