Original ArticleSymptom Prevalence in Lung and Colorectal Cancer Patients

Context.Relatively few data are available about symptoms among cancer patients.ObjectivesTo describe the prevalence and severity of symptoms among a large, representative cohort of newly diagnosed cancer patients.MethodsWe collected survey data about symptoms (pain, fatigue, depression, nausea/vomiting, cough, dyspnea, and diarrhea) from 5422 patients with incident lung and colorectal cancer from the diverse, nationally representative Cancer Care Outcomes Research and Surveillance Consortium cohort. We described the prevalence of any symptoms and moderate/severe symptoms approximately four to six months after diagnosis. We used logistic regression to identify patient and clinical characteristics associated with symptoms, and calculated adjusted proportions of patients with symptoms.ResultsIn total, 5067 (93.5%) patients reported at least one symptom in the four weeks before their survey, with 51% reporting at least one moderate/severe symptom. Lung cancer patients reported more symptoms than colorectal cancer patients. Patients who received treatment or had more comorbidities were more likely to report symptoms. For example, after adjustment, patients who received chemotherapy during the six weeks before the survey were more likely than others to report at least one symptom (97.3% vs. 90.8%, P < 0.001), and at least one moderate/severe symptom (56.8% vs. 46.2%, P < 0.001). After adjustment, early- vs. late-stage patients did not differ in reports of at least one symptom (93.6% vs. 93.4%, P = 0.853) and differed only slightly in reports of at least one moderate/severe symptom (53.3% vs. 49.6%, P = 0.009).ConclusionMost recently diagnosed lung and colorectal cancer patients have cancer-related symptoms regardless of stage, and more than half have at least one moderate/severe symptom.
