Hospitalization of hyperglycemic lung cancer patients during treatment
9560 Background: Approximately 20 million Americans have type 2 diabetes mellitus. This same group is at significant risk of developing malignancy. Evidence suggest that diabetics with colon and breast cancer experience inferior treatment outcomes. There are few direct comparisons of treatment outcome and/or treatment tolerability in those with and without hyperglycemia. There are no such comparisons in lung cancer patients. We anticipate those with hyperglycemia will tolerate treatment less well than those with euglycemia. With this premise, we assessed hospitalization risk between lung cancer patients with normal or elevated baseline serum glucose (BSG) prior to initial chemotherapy cycle. Methods: After obtaining institutional IRB approval, tumor registry analysis identified 364 consecutive individuals diagnosed with lung cancer between 2005 and 2007 at our institution. One hundred and fifteen were excluded: 71 not treated, 17 duplicate entries, 16 stage 1A lung cancer, 8 missing data, 2 glucose under 60 mg/dl, 1 admitted for chemotherapy. Demographic and cancer specific data were obtained from the registry. Chart review yielded: BSG, date of first chemotherapy cycle, date of hospitalization, neutrophil count at admission, radiation therapy 30 days before/after treatment. Data presented was analyzed using multivariate logistic regression. We utilized WHO strata for fasting whole blood glucose measurements. Those presenting with grade 3 (or greater) neutropenia were excluded. Results: See Table . Conclusions: Lung cancer patients with hyperglycemia are more likely to be hospitalized in the 30 days following their first cycle of cytotoxic chemotherapy. We used the WHO glucose strata to analyze our data. Compared to those with normal BSG, those with BSG between 110 and 126 mg/dl were twice as likely to be hospitalized, and those with BSG over 126 mg/dl had four times the risk. We feel this simple metric will improve clinician's treatment decisions. Prospective analysis of diabetic cancer outcomes is needed.
