Camera-based FDG PET and⁶⁷Ga SPECT in Evaluation of Lymphoma: Comparative Study

Abstract

In this selected group of patients with lymphoma, camera-based FDG PET allowed a significantly more accurate definition of active disease compared with that allowed with 67Ga scintigraphy.

Long‐term clinical outcome of Helicobacter pylori eradication for gastric mucosa‐associated lymphoid tissue lymphoma with a reference to second‐line treatment

“…24 EUS was performed to evaluate the depth of tumor invasion and the degree of perigastric lymphadenopathy in all patients. 12 According to the Lugano International Conference classification for gastrointestinal lymphoma, 25 79 patients were classified with Stage I disease, 11 with Stage II 1 disease, and 6 with Stage IVdisease.…”

Prognostic impact of pre-transplantation computed tomography and 67gallium scanning in chemosensitive diffuse large B cell lymphoma patients undergoing hematopoietic stem-cell transplantation

“…Despite these results, it is important to point out that two patients with both negative CT and 67 Ga scans as well as three patients with positive CT scan but negative 67 Ga scan (two of them had focal 67 Ga scan activity, one at mediastinum and the other at maxillary bone, and both were treated with local radiotherapy after transplantation reaching CR) eventually relapsed after transplantation, suggesting that in a small proportion of patients CT and 67 Ga scans were unable to detect minimal residual disease. Nowadays, PET has emerged as the best functional technique for most authors to evaluate patients with lymphoma owing to its higher resolution [32][33][34][35][36][37][38][39], although some groups have recently reported similar results for both functional imaging techniques [40]. In patients undergoing SCT, PET could contribute to a more precise evaluation [41][42][43][44][45].…”

Risk-adapted BEACOPP regimen can reduce the cumulative dose of chemotherapy for standard and high-risk Hodgkin lymphoma with no impairment of outcome

“…Recent studies have demonstrated the superiority of FDG-PET over 67 Ga scanning in terms of specificity, sensitivity, and accuracy. 17 The accuracy of early interim FDG-PET as an independent predictive factor of disease progression was recently evaluated in 85 patients with HD. The 5-year PFS was 91% for patients with an interim negative PET scan compared with 38% for those with an interim positive PET.…”
