Women know, and men wish they knew, prognostic information in advanced cancer.

9037 Background: Little is known about gender differences in advanced cancer patient communication with oncologists. The few studies conducted have explored differences in preferences for prognostic disclosure. Our data allow us to test for gender differences in actual rates of audio-recorded, patient and oncologist reported, prognostic disclosures. We studied a group of advanced cancer patients to determine whether gender disparities exist in: a.) reported rates of prognostic disclosures from physicians and b.) willingness to estimate (versus not) one’s prognosis (i.e., amount of time left to live). Among patients who report never receiving a prognosis from their physician, we also tested for gender difference in wishing that this had been discussed. Methods: Coping with Cancer II is an NCI -funded multi-site, prospective longitudinal study of advanced cancer patients. Patients were interviewed after receiving scan results and asked if they have received a prognosis from their oncologist either at their most recent visit or at any time in the course of their disease. They are also asked if they would be willing to estimate their prognosis. Patients who state that they have not received a prognosis are asked if they wish that they had. Results: Among the advanced cancer patients studied (N=51; men=23, women=28), male cancer patients were significantly more likely to state never receiving a prognosis from their physician than female patients (OR=3.5; χ2=4.49, df=1, p=0.034). Male cancer patients were also significantly less willing to provide a life-expectancy estimate (OR=5.6; χ2=5.06, df=1, p=0.025). Among patients who stated never receiving a prognosis (N=27; men=16, women=11), male patients tended to be more likely than female patients to wish that their prognosis had been discussed (OR=7.8; χ2=3.11, df=1, p=0.078). Conclusions: Male advanced cancer patients are less likely than female cancer patients to state that they have received prognostic information and less willing to provide a life-expectancy estimate. Although male patients receive less open prognostic disclosure than female patients, male patients tend to be more likely than female patients to want prognostic information.

Demographic aspects of Chrysomya megacephala (Diptera, Calliphoridae) adults maintained under experimental conditions: reproductive rate estimates

The objective of this work was to evaluate some aspects of the populational ecology of Chrysomya megacephala, analyzing demographic aspects of adults kept under experimental conditions. Cages of C. megacephala adults were prepared with four different larval densities (100, 200, 400 and 800). For each cage, two tables were made: one with demographic parameters for the life expectancy estimate at the initial age (e0), and another with the reproductive rate and average reproduction age estimates. Populational parameters such as the intrinsic growth rate (r) and the finite growth rate (lambda) were calculated as well.
