Key Points• The overall response rate following 4 induction cycles of VTD prior to ASCT is higher than that of 4 cycles of VCD.The Intergroupe Francophone du Myélome conducted a randomized trial to compare bortezomib-thalidomide-dexamethasone (VTD) with bortezomib-cyclophosphamidedexamethasone (VCD) as induction before high-dose therapy and autologous stem cell transplantation (ASCT) in patients with newly diagnosed multiple myeloma. Overall, a total of 340 patients were centrally randomly assigned to receive VTD or VCD. After 4 cycles, on an intent-to-treat basis, 66.3% of the patients in the VTD arm achieved at least a very good partial response (primary end point) vs 56.2% in the VCD arm (P 5 .05). In addition, the overall response rate was significantly higher in the VTD arm (92.3% vs 83.4% in the VCD arm; P 5 .01). Hematologic toxicity was higher in the VCD arm, with significantly increased rates of grade 3 and 4 anemia, thrombocytopenia, and neutropenia. On the other hand, the rate of peripheral neuropathy (PN) was significantly higher in the VTD arm. With the exception of hematologic adverse events and PN, other grade 3 or 4 toxicities were rare, with no significant differences between the VTD and VCD arms. Our data support the preferential use of VTD rather than VCD in preparation for ASCT.

Summary Myeloproliferative disorders (MPD) are reported in 25–65% of patients with splanchnic vein thrombosis (SVT). Diagnostic criteria for MPD have not been fully established in this context. Using clusters of abnormal megakaryocytes in bone marrow (BM) biopsy as a reference standard for Philadelphia negative MPD, we assessed the relevance of other criteria currently recommended for the diagnosis of MPD in SVT (128 consecutive SVT patients). First, usual criteria were compared with BM results: endogenous erythroid colony formation (EEC) was strongly correlated with BM results; splenomegaly, blood cell count, total red cell volume, erythropoietin level and cytogenetic were much less accurate. Then, patients were assigned to three groups according to the combination of BM and EEC findings (group I: both present; group II: both absent; group III: other patients); clinical presentation and outcome were compared in each group. At a mean follow‐up of 6·09 ± 6·6 years, progression to a severe form of MPD occurred in 7 of 31 group I patients (23%), in 1 of 34 group III patients (3%) and 0 of 63 group II patients. The combination of marked splenomegaly and platelet count >200 × 109/l was restricted to groups I and III. In conclusion, in patients with SVT, BM findings and EEC allowed the diagnosis of MPD at risk of aggravation. Marked splenomegaly in association with platelet counts >200 × 109/l constitute a simple index with high specificity but low sensitivity.

The aims of this study were to define the initial characteristics, natural history, and prognostic factors of patients with ophthalmologic and intraocular malignant lymphoma. All patients treated at the Institut Curie for lymphoma with ophthalmologic (orbit and/or adnexa) or intraocular involvement were retrospectively reviewed. A pathological review of all cases was performed according to the WHO classification. One hundred and forty-five patients were selected for the study. Pathological review showed 36% MALT type lymphoma, 22% lymphoplasmocytic lymphoma, and 15% diffuse large B-cell lymphoma. Ophthalmologic and ocular sites were intra-orbital in 61 cases (42%) and conjunctival in 51 cases (35%), with bilateral involvement in 10% of cases. Stage IV was found in 32% of cases, with bone marrow involvement in 12%. With a median follow-up of 90 months, the 5-year DFS and OS were 64 and 79% for low-grade NHL, and 43 and 50% for high-grade NHL. On multivariate analysis, age greater than 59 years, elevated LDH level, stage IV, high-grade histological subgroup, and presence of B-symptoms had a negative impact on OS for the overall population. In conclusion, with a median follow-up of 7.5 years, our large cohort of patients represents one of the largest published series on primary ophthalmologic and intraocular malignant lymphoma.

Purpose: Recently, a new ABC protein, breast cancer resistance protein (BCRP), was described. But its prognosis is not known in acute myeloid leukemia (AML). In addition, the prognosis of P-glycoprotein (Pgp) and BCRP in patients treated homogeneously by the same anthracycline (daunorubicin, idarubicin, or mitoxantrone) during all of the treatment with aracytine is not known. Therefore, we have evaluated the relationship between drug resistance phenotype, in vitro anthracene sensitivity, and the relation to treatment outcome.Experimental Design: We have analyzed 149 AML treated according to protocol of the European Organization for Research and Treatment of Cancer group. The prognostic value of BCRP and Pgp were analyzed in the whole population and according to intercalating agent.Results: BCRP was a prognostic factor, for achievement of complete remission (43% in positive patients and 69% in negative patients, P ‫؍‬ 0.005), the 4-year disease-free survival (12% versus 33%, P ‫؍‬ 0.03), and the 4-year overall survival (19% versus 38%, P ‫؍‬ 0.003). When BCRP expression and Pgp function were categorized in three groups, ؉/؉, ؉/؊ or ؊/؉, and ؊/؊, the achievement of complete remission was 45%, 66%, and 90% (P ‫؍‬ 0.0003), the 4-year disease-free survival was 8%, 26%, and 40% (P ‫؍‬ 0.01), and the 4-year overall survival was 16%, 37%, and 48% (P ‫؍‬ 0.001), respectively. Pgp function was a prognostic factor in patients treated by daunorubicin and idarubicin but not by mitoxantrone. In contrast, BCRP expression was a prognostic factor in patients treated by daunorubicin and mitoxantrone but not by idarubicin.Conclusions: BCRP would be implicated in the resistance to chemotherapies in AML. But these are the patients expressing both BCRP and Pgp who have the poorest prognosis.
