Little is known about the prevalence of anxiety disorders among long-term survivors of adult cancers. Using data from the National Comorbidity Survey Replication (NCS-R), we compared rates of anxiety disorders between long-term cancer survivors and individuals without a history of cancer.
A nationally representative sample of 9282 adults participated in a household survey to assess the prevalence of DSM-IV psychiatric disorders, a subset of whom also answered questions about medical comorbidities, including cancer. Long-term survivors were defined as those who received an adult cancer diagnosis at least 5 years before the survey. Multiple logistic regression analyses were used to examine associations between cancer history and anxiety disorders in the past year.
The NCS-R sample consisted of 225 long-term cancer survivors and 5337 people without a history of cancer. Controlling for socio-demographic variables, long-term cancer survivors were more likely to have an anxiety disorder (odds ratio [OR]: 1.49, 95% confidence interval [CI]: 1.04-2.13), including specific phobia (OR: 1.59, 95% CI: 1.06-2.44) and medical phobia (OR: 3.45, 95% CI: 1.15-10.0), during the past 12 months compared with those without cancer histories. Rates for social anxiety disorder, generalized anxiety disorder, posttraumatic stress disorder, panic disorder, and agoraphobia were not significantly different between groups.
Long-term survivors of adult cancers were more likely to have an anxiety disorder diagnosis, namely specific phobia, in the past 12 months compared with the general public. Further longitudinal study is needed to clarify the timing and course of anxiety relative to the cancer diagnosis.

    ABSTRACT: Evidence that long-term cancer survivors (LTCS) experience greater cognitive dysfunction than individuals without cancer is mixed. This analysis of a population-based sample of United States residents compares self-reported cognitive difficulties in LTCS and cancer naïve controls (CNC), controlling for psychiatric disorders. National Comorbidity Survey-Replication (NCS-R) interviews were conducted in a nationally-representative sample of 9282 people, of whom 5692 were assessed for cancer history. Long-term survivors of adult cancers were defined as individuals who were at least 18 years old at time of diagnosis; greater than 5 years following diagnosis; and with cancer reportedly in remission or cured. Cognitive dysfunction queries included two screening questions and five items drawn than the World Health Organization (WHO) Disability Assessment Schedule 2.0. Psychiatric disorders were identified using the WHO's Composite International Diagnostic Interview. Odds ratios and 95% confidence intervals were obtained from multivariable logistic regression models fit to evaluate the relationship between cancer status (LTCS versus CNC) and cognitive symptoms. Of NCS-R participants, 225 met criteria for LTCS and 3953 for CNC. Long-term cancer survivors and CNC screened positive for cognitive symptoms at a rate of 19.5% and 20.8%, respectively, for the first screen and 16.0% and 16.4%, respectively, for the second. Adjusting for demographic and psychiatric variables, LTCS did not carry increased odds of experiencing cognitive symptoms [(OR) 1.00 (95% CI, .59 to 1.68); (OR) .95 (95 %CI, .57 to 1.59)]. Self-reported cognitive symptoms are common among LTCS and CNC. LTCS do not report cognitive symptoms with greater frequency.

    ABSTRACT: BACKGROUND: Cancer survival has improved in the past 20 years, affecting the long-term risk of mood disorders. We assessed whether depression and anxiety are more common in long-term survivors of cancer compared with their spouses and with healthy controls. METHODS: We systematically searched Medline, PsycINFO, Embase, Science Direct, Ingenta Select, Ovid, and Wiley Interscience for reports about the prevalence of mood disorders in patients diagnosed with cancer at least 2 years previously. We also searched the records of the International Psycho-oncology Society and for reports that cited relevant references. Three investigators independently extracted primary data. We did a random-effects meta-analysis of the prevalences of depression and anxiety in cancer patients compared with spouses and healthy controls. FINDINGS: Our search returned 144 results, 43 were included in the main analysis: for comparisons with healthy controls, 16 assessed depression and ten assessed anxiety; of the comparisons with spouses, 12 assessed depression and five assessed anxiety. The prevalence of depression was 11·6% (95% CI 7·7-16·2) in the pooled sample of 51 381 cancer survivors and 10·2% (8·0-12·6) in 217 630 healthy controls (pooled relative risk [RR] 1·11, 95% CI 0·96-1·27; p=0·17). The prevalence of anxiety was 17·9% (95% CI 12·8-23·6) in 48 964 cancer survivors and 13·9% (9·8-18·5) in 226 467 healthy controls (RR 1·27, 95% CI 1·08-1·50; p=0·0039). Neither the prevalence of depression (26·7% vs 26·3%; RR 1·01, 95% CI 0·86-1·20; p=0·88) nor the prevalence of anxiety (28·0% vs 40·1%; RR 0·71, 95% CI 0·44-1·14; p=0·16) differed significantly between cancer patients and their spouses. INTERPRETATION: Our findings suggest that anxiety, rather than depression, is most likely to be a problem in long-term cancer survivors and spouses compared with healthy controls. Efforts should be made to improve recognition and treatment of anxiety in long-term cancer survivors and their spouses. FUNDING: None.

    ABSTRACT: To determine how age may modulate the association of a history of cancer with a 12-month history of anxiety and depressive disorders. The authors used population-based, cross-sectional surveys, the Collaborative Psychiatric Epidemiology Surveys. These surveys were conducted in the United States in 2001-2003 and included 16,423 adult participants, of whom 702 reported a cancer history. The Composite International Diagnostic Interview evaluated the presence of a 12-month history of anxiety and depressive disorders. Among those with a cancer history, older adults (≥60 years old) were less likely than younger adults (18-59 years old) to have a 12-month history of an anxiety or depressive disorder. Compared with their peers without cancer, younger adults with a cancer history had more anxiety (23.8% versus 13.9%) and depressive (16.0% versus 9.5%) disorders, whereas older adults with a cancer history had lower levels of anxiety (3.7% versus 6.3%) and depressive (1.9% versus 3.9%) disorders. In multivariable modeling, there was a statistically significant interaction between age group and cancer history, with the risk for anxiety and depressive disorders elevated in the younger age group with a cancer history (odds ratio: 5.84 and odds ratio: 6.13, respectively) but decreased in the older age group with a cancer history (odds ratio: 0.55 and odds ratio: 0.45, respectively). The authors' findings suggest a considerable age-dependent variation with regard to anxiety and depressive disorders in adults with a cancer history. Investigation of the mechanisms contributing to this apparent age differential in risk could have important mental illness treatment implications in this population.
