Article:
Chronic fatigue syndrome and subsequent risk of cancer among elderly US adults 
– Source: Cancer, May 30, 2012

by Cindy M Chang, Joan L Warren, Eric A Engels

[Note: an OR (odds ratio) of 1.0 would signify no difference in average risk between CFS & non-CFS populations. An OR of 1.88, for example, would indicate an 88% greater average risk for the CFS population. OR of 1.51 would be 51% greater average risk, and so on.]

Abstract:
Summary: Using US linked registry data on 1.2 million cancer cases and 100,000 population-based controls, risk was evaluated for a wide range of cancer types following a diagnosis of chronic fatigue syndrome. A strongly significant elevated risk was found for non-Hodgkin lymphoma associated with chronic fatigue syndrome, and in particular, associations for 2 specified non-Hodgkin lymphoma subtypes (diffuse large B cell lymphoma and marginal zone lymphoma).

Background: The cause of chronic fatigue syndrome (CFS) is unknown but is thought to be associated with immune abnormalities or infection.

Because cancer can arise from similar conditions, associations between CFS and cancer were examined in a population-based case-control study among the US elderly.

Methods: Using linked Surveillance, Epidemiology, and End Results (SEER)-Medicare registry data, approximately 1.2 million cancer cases and 100,000 controls (age range, 66-99 years; 1992-2005) were evaluated.

CFS was identified in the period more than 1 year prior to selection, using linked Medicare claims. Unconditional logistic regression was used to estimate the odds ratios (ORs) comparing the CFS prevalence in cases and controls, adjusting for age, sex, and selection year. All statistical tests were 2-sided.

Results:

• CFS was present in 0.5% of cancer cases overall and 0.5% of controls [1 in 200 people in Medicare database].

• CFS was associated with an increased risk of non-Hodgkin lymphoma (NHL) (OR = 1.29, 95% confidence interval [CI] = 1.16-1.43, P = 1.7 × 10?6th).

• Among non-Hodgkin lymphoma subtypes, CFS was associated with diffuse large B cell lymphoma (OR = 1.34, 95% CI = 1.12-1.61), marginal zone lymphoma (OR = 1.88, 95% CI = 1.38-2.57), and B cell NHL not otherwise specified (OR = 1.51, 95% CI = 1.03-2.23).

CFS associations with non-Hodgkin lymphoma overall and NHL subtypes remained elevated after excluding patients with medical conditions related to CFS or non-Hodgkin lymphoma, such as autoimmune conditions.

CFS was also associated, although not after multiple comparison adjustment, with cancers of the pancreas (OR = 1.25, 95% CI = 1.07-1.47), kidney (OR = 1.27, 95% CI = 1.07-1.49), breast (OR = 0.85, 95% CI = 0.74-0.98), and oral cavity and pharynx (OR = 0.70, 95% CI = 0.49-1.00).

Conclusions:
Chronic immune activation or an infection associated with CFS may play a role in explaining the increased risk of non-Hodgkin lymphoma.

Correlation strength

Thank you for posting this article.

I suggest that the OR demonstrates "mild" or "moderate" association between CFS and NHL.

"Strong" is like smoking and lung cancer - OR of 11.

What about younger patients?

This only looked at the correlation for ages 66-99. How can we know if the same increased risk applies to younger ages groups as well? I'm 37 and wondering how much I really need to worry about this right now.
