Abstract
OBJECTIVE: To assess the role of interim [18F]-Fluoro-2-deoxy-d-glucose positron emission tomography scan/computed tomography scan in the management of diffuse large B-cell lymphoma in terms of progression-free survival and overall survival prediction.
METHODS: The retrospective study was conducted at the Shaukat Khanum Memorial Cancer Hospital, Lahore, and comprised data of newly diagnosed patients of diffuse large B-cell lymphoma treated between January 2010 and June 2013.Baseline characteristics of patients were documented and compared. Response on interim positron emission tomography/computed tomography and end of treatment scan was taken a look at, and .progression-free survival and overall survival for positive/negative scans were calculated. Data was also reviewed for sensitivity, specificity, positive predictive value and negative predictive value for relapse. SPSS 19 was used for statistical analysis.
RESULTS: Data of 119 patients was reviewed, and 87(73%) of them were males. Overall median age was 33 years (range 18-50). Interim scan was positive for 63(53%) patients and negative for 53(47%), and showed positive predictive value, negative predictive value, sensitivity and specificity for relapse of 35%, 89%, 79% and 55% respectively. Two-years progression-free survival and overall survival for scan-positive patients was 66% and 72% compared to 88% (p=0.002) and 92% (p=0.005) for scan-negative patients. Corresponding values at 2 years for patients having positive end-of-treatment scan were 35% and 44% against 94% (p< 0.001) and 96%(p< 0.001) for patients with negative scan.
CONCLUSIONS: Interim positron emission tomography/computed tomography had high sensitivity and negative predictive value for relapse in diffuse large B-cell lymphoma. Both interim and end-of-treatment scans were predictors of progression-free survival and overall survival.
