Importance of Histologic Verification of Positive Positron Emission Tomography/Computed Tomography Findings in the Follow-Up of Patients With Malignant Lymphoma.

Introduction: Posttherapy positron emission tomography/computed tomography (PET/CT) scanning in patients with malignant lymphoma remains controversial. We aimed to evaluate the utility of achieving histologic verification of positive PET/CT findings in the follow-up of patients with malignant lymphoma.

Patients And Methods: A total of 771 PET/CT scans were performed as posttherapy follow-up in 190 lymphoma patients who had experienced a complete remission at our institution.

Cytomegalovirus reactivation in patients with multiple myeloma.

The introduction of novel antimyeloma agents has improved the outcome of multiple myeloma (MM) dramatically. However, it has also led to an increasing incidence of Herpesviridae family virus infections, including a high incidence of post-transplant cytomegalovirus (CMV) reactivation after treatment with novel agents. We herein retrospectively assessed the CMV reactivation in all 120 newly diagnosed patients with MM consecutively seen and treated at our hospital.
