Age and rural residence effects on accessing colorectal cancer treatments: a registry study.

OBJECTIVES: To test the hypotheses that older patients with colorectal cancer (CRC) and rural patients are less likely to undergo surgery, radiation, and chemotherapy. STUDY DESIGN: Retrospective study. METHODS: A total of 6561 patients with CRC between January 1998 and December 2003 were identified by incident International Classification of Diseases for Oncology codes from the Nebraska Cancer Registry. In multivariate logistic regression analyses, we studied the association of age and residence county (rural vs urban and micropolitan) with each of 3 CRC treatments by anatomic site. RESULTS: After adjusting for patient demographics, insurance payer, ratio of providers to population, and cancer stage, patients with colon cancer living in micropolitan counties were more likely to receive chemotherapy than those living in rural counties (P <.001). Compared with patients aged 19 to 64 years, patients with colon cancer 85 years and older (P <.001) and patients with rectal cancer 75 years and older (P <.05) were less likely to undergo surgery. Patients with CRC 75 years and older were less likely to receive radiation, and patients with colon cancer 65 years and older and patients with rectal cancer 75 years and older were less likely to receive chemotherapy (P <.001 for both). CONCLUSIONS: In Nebraska, older patients with CRC were less likely to undergo surgery, radiation, and chemotherapy. Patients with colon cancer in rural counties were less likely to undergo chemotherapy than those in micropolitan counties. Decision makers need to consider issues of age and rural residence in patient access to CRC treatments.

Prospective study of survival outcomes in Non-Hodgkin's lymphoma patients with rheumatoid arthritis.

PURPOSE: Although preliminary studies suggest that non-Hodgkin's lymphoma (NHL) complicating rheumatoid arthritis (RA) may be a clinically distinct entity compared with that occurring in the general population, studies examining the impact of antecedent RA on survival are limited. In this prospective study, we examined the association of RA with survival in patients with NHL. PATIENTS AND METHODS: Using two large lymphoma registries, we identified patients with evidence of RA preceding NHL. Survival in RA patients was compared with that of controls using proportional hazards regression, adjusting for the effects of age, sex, lymphoma diagnosis-to-treatment lag time, calendar year, International Prognostic Index score, and NHL grade. RESULTS: The frequency of NHL subtypes was similar in RA patients (n = 65) and controls (n = 1,530). Compared with controls, RA patients with NHL had similar overall survival (hazard ratio [HR] = 0.95; 95% CI, 0.70 to 1.30) but were at lower risk of lymphoma progression or relapse (HR = 0.41; 95% CI, 0.25 to 0.68) or death related to lymphoma or its treatment (HR = 0.60; 95% CI, 0.37 to 0.98), but were more than twice as likely to die from causes unrelated to lymphoma (HR = 2.16; 95% CI, 1.33 to 3.50). CONCLUSION: RA is associated with improved NHL-related outcomes, including a 40% reduced risk of death occurring as a result of lymphoma or its treatment and approximately a 60% lower risk of lymphoma relapse or progression compared with non-RA controls. However, the survival advantage gained in RA from the acquisition of lymphomas with favorable prognoses is negated through an increased mortality from other comorbid conditions.
