The effect of changes in tumor volume and the level of FDG absorption on the duration of progression-free survival in patients with lymphomas

The article presents the results of an assessment of the relationship between metabolic parameters – tumor volume and the level of fluorodeoxyglucose absorption and the duration of progression-free survival in patients with 3 points on the PET scale. The purpose of the work is to find the relationships between the values and the duration of the period of PFS. In the course of the work, the average values of FDG absorption and tumor volume in patients with different periods of PFS were measured and compared. It was revealed that patients with a PFS period of more than 24 months have statistically significant differences in these parameters. These results can be interpreted as an additional factor in the course and prognosis of the disease in patients with lymphomas after treatment and a score of 3 points on the PET scale.
