Summary of "Interim PET-CT-guided therapy in elderly patients with Hodgkin lymphoma-a retrospective national multi-center study."

Hodgkin lymphoma (HL), a disease of mostly young patients, also peaks in the elderly. Despite the profound improvement in the outcome of young patients, in the elderly, 5-year progression-free survival (PFS) rates are under 70%. Interim PET-CT (iPET) is known to be highly predictive for PFS in young HL patients, but it has not been sufficiently validated in the elderly patient population. In this multi-center collaboration, all consecutive elderly patients (age ≥ 60) diagnosed with HL between 1998 and 2016 were retrospectively reviewed. Baseline characteristics, outcome measures, and iPET results, classified according to the Deauville score, were recorded and analyzed. We identified 78 elderly HL patients (median age 69) who underwent iPET. ABVD was the treatment regimen in 52 (67%) patients. Eighty-three percent of patients had iPET scores of 1-3 while 17% had scores of 4-5. Patients with iPET scores of 1-3 had 5-year PFS and OS rates of 72% and 82% compared with 25% and 45%, respectively, in patients with scores of 4-5 (p < 0.001). Our findings show that iPET is highly predictive of outcome in elderly HL patients and provide evidence that iPET-guided therapy in this patient population may be key to achieving superior treatment outcome.

Medical and Biotech [MESH] Definitions

Two or more distinct types of malignant lymphoid tumors occurring within a single organ or tissue at the same time. It may contain different types of non-Hodgkin lymphoma cells or both Hodgkin and non-Hodgkin lymphoma cells.

Any of a group of malignant tumors of lymphoid tissue that differ from HODGKIN DISEASE, being more heterogeneous with respect to malignant cell lineage, clinical course, prognosis, and therapy. The only common feature among these tumors is the absence of giant REED-STERNBERG CELLS, a characteristic of Hodgkin's disease.

A form of non-Hodgkin lymphoma having a usually diffuse pattern with both small and medium lymphocytes and small cleaved cells. It accounts for about 5% of adult non-Hodgkin lymphomas in the United States and Europe. The majority of mantle-cell lymphomas are associated with a t(11;14) translocation resulting in overexpression of the CYCLIN D1 gene (GENES, BCL-1).

Clinically benign, histologically malignant, recurrent cutaneous T-cell lymphoproliferative disorder characterized by an infiltration of large atypical cells surrounded by inflammatory cells. The atypical cells resemble REED-STERNBERG CELLS of HODGKIN DISEASE or the malignant cells of CUTANEOUS T-CELL LYMPHOMA. In some cases, lymphomatoid papulosis progresses to lymphomatous conditions including MYCOSIS FUNGOIDES; HODGKIN DISEASE; CUTANEOUS T-CELL LYMPHOMA; or ANAPLASTIC LARGE-CELL LYMPHOMA.

A systemic, large-cell, non-Hodgkin, malignant lymphoma characterized by cells with pleomorphic appearance and expressing the CD30 ANTIGEN. These so-called "hallmark" cells have lobulated and indented nuclei. This lymphoma is often mistaken for metastatic carcinoma and MALIGNANT HISTIOCYTOSIS.
