BackgroundThe oncology patient population is vulnerable to elevated levels of anxiety and depression. These states of psychological distress have been associated with negative effects on treatment course and outcomes, but reported prevalence rates are varied. The General Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) questionnaires are screening tools that can be utilized to assess the levels of anxiety and depression, respectively.MethodsThis prospective, surgeon-blinded study assessed the preoperative prevalence of anxiety and depression in patients with abdominal malignancies who underwent curative-intent resection. Postoperative outcomes and survival were assessed.ResultsOverall, 218 patients were enrolled and included in the final analysis. Patients were stratified into groups by severity of anxiety and depression. 67 (31 %) patients reported at least mild anxiety as defined by GAD-7 score of 5 +, and 74 (34 %) patients reported at least mild depression, as defined by PHQ-9 score of 5 +. Functional status as defined by Eastern Cooperative Oncology Group scores was associated with anxiety (P = 0.003) and depression (P = 0.024). Depression was associated with race and ethnicity (P = 0.014) and marital status (P = 0.021), with Hispanic/Latino and unpartnered patients reporting higher rates of depression.ConclusionAnxiety and depression are common in the surgical oncology population, affecting a third of the patient population in this prospective study. In addition to a thorough social assessment, the GAD-7 and PHQ-9 questionnaires can be utilized preoperatively to identify patients with psychological distress.SynopsisAnxiety and depression were assessed preoperatively in patients with abdominal malignancies who underwent curative-intent resection. These states of psychological distress were highly prevalent, affecting a third of the population, and significantly associated with certain vulnerable groups.
