Symptom Clusters and Relationships to Symptom Interference with Daily Life in Taiwanese Lung Cancer Patients

Abstract

The number one cause of cancer death in Taiwan is lung cancer. Of the few studies describing the experience of patients living with lung cancer, most use bivariate analyses to test associations between individual symptoms. Few have systematically investigated multiple symptoms. This prospective study was undertaken to explore the phenomenon of symptom distress, to investigate the presence of symptom clusters, and to examine the relationship of symptom clusters to symptom interference with daily life in Taiwanese lung cancer patients. A sample of 108 lung cancer patients was recruited using the Taiwanese version of the M. D. Anderson Symptom Inventory. Data were analyzed by hierarchical cluster analysis, factor analysis, Pearson correlation, t-test, and regression analysis. The top five most-severe symptoms were fatigue, sleep disturbance, lack of appetite, shortness of breath, and general distress. Factor analysis generated a two-factor solution (general and gastrointestinal symptoms) for symptom severity items. Consistent with the result from factor analysis, cluster analysis also indicated the same two cluster groups (general and gastrointestinal symptoms). Both clusters were significantly correlated with symptom interference items; however, the general symptom cluster presented higher correlation coefficients than did the gastrointestinal symptom cluster. These results provide an important basis for developing novel strategies to manage multiple symptoms in lung cancer patients and thereby improve their well-being.

Symptom clusters and quality of life in China patients with lung cancer undergoing chemotherapy

“…This result was similar to that from previous studies [16][17][18]. Concerning severity of symptoms, our result showed fatigue, dry mouth, and shortness of breath as the most severe, was similar to Semiha Akin 's [19] findings.…”

Symptom clusters in patients with lung cancer: a literature review

“…Five studies published between 1997 and 2009 reporting empirically determined symptom clusters associated with lung cancer were identified (Table 1) [21,[28][29][30][31]. The primary end point for three of the five studies was to identify symptom clusters [28][29][30].…”

Visualizing clinical predictors of febrile neutropenia in Asian cancer patients receiving myelosuppressive chemotherapy

“…12,13 Factor analysis, a similar technique, has also been used to identify different symptom clusters in lung cancer patients. 14,15 The utilization of these data reduction techniques in FN analysis can enable the identification of specific patient groups by narrowing the number of risk factors that clinically predicts FN in our local population. This will allow the tailoring of G-CSF therapies so that FN treatment can be further optimized in clinical practice.…”
