We hypothesized that older age, female gender, and the presence of comorbid illness would be associated with proximal cancers. METHODS: Incident cases of colorectal cancer (n=9,550) occurring in 1994 were identified from Florida's population-based statewide cancer registry. We categorized colorectal cancers as either proximal (cecum, ascending colon, and transverse colon) or distal (descending colon, sigmoid colon, rectosigmoid, and rectum). Multiple logistic regression analysis was used to determine the multivariable relationship between clinical characteristics and the odds of a proximal-occurring lesion. RESULTS: Four characteristics emerged as independent predictors of a proximal lesion. Each year of increasing age was associated with a 2.2 percent increase in the odds of a proximal lesion, whereas female gender was associated with a 38 percent increase in the odds of a proximal lesion. The presence of a comorbid condition was associated with a 28 percent greater odds of a proximal lesion, and, finally, black, non-Hispanic race was associated with a 24 percent greater odds of a proximal lesion. CONCLUSIONS: We found that increasing age, female gender, black, non-Hispanic race, and the presence of comorbid illnesses were factors associated with a greater likelihood of developing colorectal cancer in a proximal location. Further studies will be required to confirm these findings and to establish the mechanism by which comorbidity influences the site of colorectal cancer development.

The authors examined treatments and adjusted risk of death (through 1997) for all incident cases of breast carcinoma occurring in Florida in 1994 (n = 11,113) by using state tumor registry data. Patients lacking health insurance were less likely to receive breast-conserving surgery (BCS) compared with patients who had private health insurance. Among patients insured by Medicare, those belonging to a health maintenance organization (HMO) were more likely to receive BCS but less likely to receive radiation therapy after BCS. Non-Hispanic African Americans had higher mortality rates even when stage at diagnosis, insurance payer, and treatment modalities used were adjusted in multivariate models (adjusted risk ratio [RR], 1.35; 95% confidence interval [CI], 1.12-1.61; P = 0.001). Patients who had HMO insurance had similar survival rates compared with those with fee-for-service (FFS) insurance. Among non-Medicare patients, mortality rates were higher for patients who had Medicaid insurance (RR, 1.58, 95% CI, 1.18-2.11; P = 0.002) and those who lacked health insurance (RR, 1.31; 95% CI, 1.03-1.68; P = 0.03) compared with patients who had commercial FFS insurance. There were no insurance-related differences in survival rates, however, once stage at diagnosis was controlled. As a result of later stage at diagnosis, patients with breast carcinoma who were uninsured, or insured by Medicaid, had higher mortality rates. Mortality rates were also higher among non-Hispanic African Americans, a finding that was not fully explained by differences in stage at diagnosis, treatment modalities used, or insurance payer.

As an application, we prove a quantum version of an abelianization formula of S. Martin relating invariants of geometric invariant theory quotients by a group and its maximal torus; this is a version of the "abelian/non-abelian" conjecture of Bertram, Ciocan-Fontanine, and Kim. As sample applications we give a formula for a solution to the quantum differential equation (qde) for the moduli space of points on the projective line and a solution to the twisted qde for Atiyah-Drinfeld-Hitchin-Manin quiver moduli.
