Abstract Fludarabine and rituximab are commonly used in combination in the treatment of Waldenstrom’s macroglobulinemia (WM), though long term outcome of this regimen remains to be defined. We therefore examined the outcome of 43 WM patients treated on a clinical trial whose eligibility included < 2 prior therapies, and no previous nucleoside analogue or rituximab treatment. Therapy consisted of 6 cycles (25 mg/m2/day for 5 days) of fludarabine and 8 infusions (375 mg/m2/week) of rituximab over 31 weeks. 43 patients were enrolled with a median age of 61, and median prior therapies of 0. Responses were: CR (n=2); VGPR (n=14); PR (n=21); MR (n=4); for an overall and major response rate of 95.3% and 86.0%, respectively. At best response, median bone marrow disease involvement declined from 55% to 5% (p<0.00001), while serum IgM decreased from 3,840 to 443 mg/dL (p<0.00001), and hematocrit rose from 31.2% to 38.0% (p<0.0008). The median time to progression for all patients was 51.2 months, and was longer for untreated versus previously treated patients (77.6 vs. 38.4 months; p=0.017), as well as for those patients who achieved ≥ VGPR versus <VGPR (>88.3 vs. 36.9 months; p=0.049). Grade ≥ 3 toxicities included neutropenia (n=27); thrombocytopenia (n=7); pneumonia (n=6), including two patients who succumbed to non-PCP interstitial pneumonia; peripheral neuropathy (n=2); limbic encephalitis (n=1); hemolytic anemia (n=1). With a median follow-up of 40.3 months, we observed transformation to aggressive lymphoma (n=3); myelodysplasia (n=1); acute myelogenous leukemia (n=2); bladder carcinoma (n=1); and carcinoma of unknown primary (n=1) among 8 patients. The results of this study demonstrate that fludarabine and rituximab is an active regimen in WM, though short and long term toxicities need to be carefully weighed against other available treatment options.

8017 Background: Rituximab is active in Waldenstrom's macroglobulinemia (WM), producing response rates of 40–50%. Lower response rates are observed among patients with the FcγRIIIA-158 FF polymorphism; high B2M (≥3.0 mg/dL), and high serum IgM levels (≥6,000 mg/dL). Thalidomide enhances rituximab-mediated ADCC of lymphoplasmacytic cells and produces response rates of 25% in WM. As such, we conducted this phase II study using thalidomide and rituximab in patients naïve to either agent. Methods: Intended therapy was: Weeks 1–52: Thalidomide (200 mg po qHS for 2 wks, then 400 mg po qHS) Weeks 2–5, 13- 16: Rituximab (375 mg/m2/wk) Twenty-five patients were enrolled, 20 of whom were previously untreated, with a baseline median age of 62 (range 44–86 yrs), BM involvement of 40 (range 5–80%), serum IgM of 3,670 (range 924–8,610 mg/dL), B2M of 2.6 (range 1.4–8.3 mg/L), Hct of 34.1 (range 23.6–42.6%). Results: Grade ≥2 toxicities to thalidomide included neuroparesthesias (n=11); somnolence (n=3); confusion (n=3); rash (n=2); tremors (n=2); bradycardia (n=2) and palpitations (n=1). Among patients experiencing neuroparesthesias, 10 demonstrated resolution to grade 1 (n=3) or complete resolution (n=7) at a median of 6.7 (range 0.4- 22.5 months). Dose reduction of thalidomide occurred in all patients and led to discontinuation in 11 patients. Twenty-three patients were evaluable. Responses among evaluable patients: CR (n=1); PR (n=15); MR (n=2); SD (n=1) for an overall and a major response rate of 78% and 70%, respectively. Median serum IgM decreased from 3,670 (924–8,610 mg/dL) to 1,590 (36–5,230 mg/dL) (p<0.001), while median hematocrit rose from 33.0 (23.6–42.6%) to 37.6 (29.3–44.3%) (p=0.004) at best response. With a median follow-up of 42+ months, the median TTP for all evaluable patients on study was 35 months, and 38+ months for responders. Overall response was associated with median cumulative thalidomide dose: CR/PR/MR (29,275 mg) vs. SD/NR (7,400 mg); p=0.004. Overall responses were unaffected by FcγRIIIA-158 polymorphism status (81% vs. 71% for VV/FV vs. FF); serum IgM (78% vs. 80% for <6,000 vs. ≥6,000 mg/dL); and B2M levels (71% vs. 89% for <3 vs. ≥3 g/dL); p=NS. Conclusions: Thalidomide in combination with rituximab is highly active and produces long- term responses in patients with WM. No significant financial relationships to disclose.

Purpose: To present a 5-year mortal case of Waldenström’s macroglobulinemia-related retinopathy and serous macular detachment. Case report: A 63-year-old man, with unremarkable medical history, presented with bilateral decreased vision for 2 months. Fundus examination revealed bilateral scattered retinal hemorrhages, exudates, venous tortuosity, and serous macular detachment. Hematologic and biochemistry profiles showed pancytopenia with blood smear demonstrating erythrocyte rouleaux formation. Hyperviscosity syndrome was suspected and later Waldenström’s macroglobulinemia was diagnosed by bone marrow biopsy and high concentration of serum IgM. Plasmapheresis and subsequent chemotherapy were arranged. In spite of resolution of most retinal abnormalities, his visual acuity still showed no improvement with a persistent bilateral macular detachment. The patient then died 5 years after the diagnosis of Waldenström’s macroglobulinemia. Conclusions: Long-term toxicity of IgM to the retinal pigment epithelium may impede the resolution of the persistent serous macular detachment, resulting in an inability of recovery in his vision. Therefore, early diagnosis and timely reduction of serum paraproteins by plasmapheresis and chemotherapy is critical for preventing permanent damages to patients’ health and vision.
