Computerized tomography in the prognosis of XXXX .

@entity1 @entity11 @entity463 @entity5
Ninety-seven @entity1 with supratentorial @entity11 who received postoperative radiation therapy and chemotherapy at the University of California, San Francisco, from 1977 through 1984 showed improvement in their follow-up computerized tomography (CT) scans. Twenty-one of these 97 "CT responders" were designated "complete responders" because on serial CT scans they had @entity5 mass and contrast enhancement, which had been present postoperatively. In the remaining 76 @entity1 , CT scans showed reduction in the size, but not disappearance, of the lesions, and these were designated "partial responders." Fifty-eight partial responders had @entity463 ( @entity463 ); their median survival time was 72 weeks. The median survival time for the 11 complete responders with @entity463 has not yet been achieved, but survival at the 53rd percentile is 172 weeks. Among @entity1 with highly anaplastic astrocytoma, the median survival time was 211 weeks for the 10 complete responders and 125 weeks for the 18 partial responders. Eleven of the 21 complete responders are alive at a median postoperative follow-up time of 163 weeks (range 114 to 470 weeks). Eighteen of these @entity1 had subtotal resection of @entity5 ; three @entity1 had gross total @entity5 resections, but postoperative CT scans showed evidence of residual or possibly recurrent @entity5 within 1.5 to 4.5 months. Resolution of the @entity5 mass and contrast enhancement took 9 to 151 weeks; the time to resolution did not depend upon the configuration of the remaining @entity5 mass and contrast enhancement after surgery. In this study, @entity1 with @entity11 whose CT scans eventually showed sustained @entity5 mass and contrast enhancement had a more favorable prognosis than did @entity1 whose CT scans showed improvement, but not complete disappearance, of the @entity5 . These CT findings may prove useful in determining the prognosis of @entity1 with @entity11 .
