    Notes: Abstract Background: The promising results of fludarabine (FLU) in chroniclymphocytic leukemia have prompted its extensive evaluation in low-gradenon-Hodgkin's lymphoma (LG-NHL). Its different mechanisms of action make FLUan attractive partner for combination with other cytostatic agents. Patients and methods: We used a three-drug combination of FLU (25mg/m2 i.v. on days one to three), mitoxantrone (10mg/m2 i.v. on day one) and prednisone (40 mg per os on daysone to five) (FMP) to treat 48 patients with recurrent LG-NHL. Results: Of the 48 patients, 17 (35%) achieved complete responses(CR), 23 (48%) partial responses, while the remaining 8 (17%)showed no benefit from the treatment. The risk of lower CR rate wassignificantly correlated with the presence of advanced stage (IV) (P = 0.01),the number of previous regimens (〉3) (P = 0.006), and the follicularhistologic subtype (P = 0.02). The major toxic effects observed wereneutropenia and infections; there was only one fatality, due to drug-relatedside effects. Conclusions: These data confirm the significant efficacy of the FMPfludarabine-mitoxantrone combination regimen in obtaining a good remissionrate with moderate toxicity in a particular subset of recurrent LG-NHL.

    Notes: Abstract Background: Treatment of both Hodgkin's disease (HD) and aggressive non-Hodgkin's lymphoma (NHL) with abdominal presentation at the time of diagnosis is often followed by detection of residual masses by computed tomography (CT). However, CT is usually unable to disciminate between residual tumor and fibrosis/necrosis. We investigated the ability of fluorine-18 fluorodeoxyglucose positron emission tomography (PET) to differentiate between residual active tumor tissue and fibrosis. Patients and methods: Forty-four patients with HD or aggressive NHL presenting abdominal involvement (41% with bulky mass) were studied with CT and PET at the end of chemotherapy ± radiation therapy. Results: After treatment, seven patients had negative PET and CT, and none of them relapsed. The remaining 37 patients all had positive CT (abnormalities ≤10%). All of the 13 who also had positive PET relapsed (100%). By contrast, there was only 1 (4%) relapse among the 24 patients who were positive at CT but negative at PET. The two-year actuarial relapse-free survival rate was 95% for those with negative PET compared with 0% for positive PET patients (P 〈 0.000000). Conclusions: In lymphoma patients with abdominal masses who present CT positivity at restaging, PET should be considered the noninvasive imaging modality of choice for differentiating early recurrences or residual disease from fibrosis.
