Abstract We updated a cohort study with the aim of evaluating if an up-front Rituximab supplemented high-dose sequential chemotherapy (R-HDS), supported by autologous bone marrow transplantation (ASCT) can induce log-term remissions in Mantle Cell Lymphoma (MCL), with an acceptable toxic profile. From 1997 to 2005, 77 consecutive MCL patients, <61 year old, considered suitable for ASCT in 11 Italian cancer centres were enrolled in this study (Group 1). Their clinical outcome was compared with that of 79 age-matched historic controls treated between 1978 and 1999 with standard-dose anthracyclin or fludarabine containing regimens (group 2). The majority of both groups had an advanced stage, bone marrow infiltration and >1 IPI risk factors, while >1 extranodal sites prevailed in Group 1 and a poor ECOG-PS in Group 2. After 2–3 cycles of either doxorubicin- or cisplatin-containing chemotherapy, Group 1 received R-HDS including: HD-cyclophosphamide (CTX) 7 gr/sqm and HD-Ara-C (2 g/sqm every 12 hours for 6 days), followed by HDS HD-melphalan (180 mg/sqm) and/or HD-mitoxantrone plus melphalan (60 and 180 mg/sqm) and ASCT. Rituximab (375 mg /sqm) was given for a total of 6 doses, twice after HD-CTX and HD-Ara-C, as in vivo purging before CD34+ cells harvest and twice after ASCT. Sixty-nine patients (90%) in Group 1 completed the planned program and a median number of 6.3 x 10^6 cells CD34+/kg were transplanted. In Group 2, 85% of patients received the planned chemotherapy. The CR rate was 86% in Group 1 and 35% in Group 2 and the treatment-related mortality was 1.3% and 0.8%, respectively. Moreover, in Group 1, 4 patient developed sMDS, and 4 died of solid tumors (n=3), or septic shock (n=1). After a median follow-up of 50 months (range 3–111) in Group 1 and 37 months (range 1–141) in Group 2, the rate of 1st CCR was 65% and 14%, respectively. The 5-year projected OS, EFS and DFS were 74%, 61% and 70%, in Group 1 and 31%, 14% and 25%, in Group 2, respectively. Cox multivariate analysis failed to identify within potential prognostic markers factors predictive for OS and EFS. In conclusion, R-HDS induces long-term remissions with a manageable toxicity in patients with newly diagnosed MCL. Studies comparing this program with other intensive regimens are needed for ascertaining the role of R-HDS in the treatment of this otherwise incurable disease.

Abstract Background Advanced follicular lymphoma (FL) and mantle cell lymphoma (MCL) are incurable diseases with conventional treatment. The high dose treatment (HDT) with autologous stem cell transplantation (ASCT), however, offers a certain proportion of these patients the prospect of a prolonged disease-free and overall survival. The aim of this study was to investigate the event free survival (EFS) and overall survival (OS) in patients with FL and MCL treated with ASCT. Patients and methods Seventeen patients with FL and 29 patients with MCL were included, 15 of them were transplanted to consolidate the response to second line treatment and 24 to consolidate their first remission, respectively. All were conditioned with total body irradiation (TBI) and high dose cyclophosphamide between 2006 and 2014 and all were transplanted with peripheral blood stem cells. Results The estimated 5-year OS for FL was 87.8% (95% confidence interval [CI] 59.5%–96.8%) and for MCL 79.3% (95% CI 56.1%–91.1%), respectively. The estimated 5-year EFS for FL was 76.0% (95% CI 48.0%–90.3%) and for MCL 69.8% (95% CI 45.5%–84.8%), respectively. There were no secondary hematological malignancies observed in either group. Conclusions Based on above results, the ASCT with TBI is a good treatment option in terms of long-term survival for patients with follicular and mantle cell lymphoma demonstrating a relatively low rate of late toxicities and secondary malignancies.

Abstract Abstract 4405 Background: Mantle cell lymphoma (MCL) is a distinct incurable B-cell neoplasm with a median survival of 3 to 5 years. t(11;14)(q13;q32) is the hallmark of the disease leading to overexpression of protooncogene cyclin D1. At least 60% of MCL patients have unmutated VH genes. Chemoresistance to conventional treatment and continuous disease relapses even after high dose therapy and autologous stem cell transplantation define the clinical course of the disease. A possible cause of this frequent failures may be that t(11;14)(q13;q32) occurs in early hematopoietic precursors, capable of multilineage differentiation. Aim: evaluation of t(11;14)(q13;q32) in different hematopoietic lineages of MCL patients. Methods: Bone marrow mononuclears from 12 MCL patients (including pleomorphic and blastoid variants) were sorted by Fluorescence-Activated Cell Sorting (BD FACSVantage SE) to divide the following cell lineages: CD45+CD34+ (progenitor cells); CD45+CD5+CD19+light chain Ig (mantle cell lymphoma); CD45+CD5-CD19+ (normal B-cells); CD45+CD14+ (monocytes); CD45+CD3+ (T-cells); CD45-GlyA+ (erythrokaryocytes) and granulocytes by light scattering, excluding CD14+CD45+ cells. The purity of sorted cells was checked by flow cytometry (BD FACSCanto II) and correlated to the number of sorted cells – if there were more than 50 thousands cells the purity was more than 92% (usually more 97%), but if there were less than 20 thousands cells the purity was 80% (never less). After sorting cells in the test-tube were washed from the PBS, fixed in methanol and glacial acetic acid mixture and layered onto slides by Cytospin centrifuge (Cellspin II Tharmac). The probes have been denatured at 75°C for 2 minutes, and hybridized with dual fusion LSI IGH-CCND1 probes (Vysis Inc.) at 37°C for 17–20 hours. Signals were visualized with Olympus IX-61 microscope with triple filter cube (DAPI / FITC / TexasRed). Results: t(11;14)(q13;q32) was present in 97% of sorted mantle cell lymphoma cells (range 84–100%), whereas in cells of all other lineages including normal B-cells t(11;14)(q13;q32) was not found at all. However, direct assessment of t(11;14)(q13;q32) in CD34+CD45+ cells and in normal B-cells was difficult due to the small number of these cells. In one case (classic variant MCL) we have sorted two “independent” cell populations 1 log different in the level of expression CD5: CD5dimCD19+ and CD5+CD19+. In both subpopulations t(11;14)(q13;32) was detected in 98,5% cell nuclei, indicating no correlation between CD5 level and fusion gene expression. In three cases using together FACS and FISH we were able to detect the population of MCL cells in bone marrow as small as 0,1–0,05%, whereas histology examination and standard FISH analysis failed to detect bone marrow involvement. Conclusion: Out data give evidence for the absence of t(11;14)(q13;q32) in early hematopoetic cells. FACS allows increase FISH sensitivity in 100–1000 times. Disclosures: No relevant conflicts of interest to declare.

7560 Background: Mantle cell lymphoma remains a clinical challenge particularly for pts not candidates for consolidation with ASCT or treatment with leukemia induction regimens. Methods: We investigated sequential radioimmunotherapy (RIT) cytoreduction with tositumomab/Iodine I131 tositumomab followed by CHOP chemotherapy as initial therapy for patients either ineligible for or unwilling to undergo high dose therapy and stem cell transplantation. In addition, pts had to have less than 25% of the intratrabecular bone marrow space involved with lymphoma. Results: Twenty-five patients (pts) were enrolled but only 24 were treated with the therapeutic dose of RIT because a manufacturing problem prevented the treatment of one patient. The median age was 66 (45–80), there were 23 men and 2 women. All patients had advanced stage (III/IV) disease and bone marrow was involved in 48% and the GI tract was involved in 48% of the patients. The overall response rate (ORR) to RIT was 83% (CR/CRu 46%; PR 38%). Two pts withdrew consent following the RIT (and are censored from that point); 1 pt with disease progression requiring alternative therapy is included in EFS and OS analyses. Twenty-one pts proceeded to the CHOP consolidation and 19 completed planned therapy (1 pt died of a CVA; 1 pt chose not to complete chemotherapy after two cycles of CHOP). At the completion of delivered therapy the ORR was 86% (CR/CRu 67%, PR 19%). The median follow up is 2.1 years (0.7 to 4.2). The median EFS was 1.4 years though there have been no events beyond 1.7 years with 7 pts at risk; median OS has not been reached (92% at 2.1 years). Minimal residual disease (MRD) was evaluated with a clonotypic PCR (cPCR) capable of detecting about 1:105 tumor cells; this assay was informative in 17 pts. Following induction with RIT 6 pts (46%) were molecularly negative in blood and bone marrow. Despite the increase in clinical CR following CHOP consolidation, no additional pts became molecularly negative. Conclusions: RIT with tositumomab/iodine I131 tositumomab is a very active agent in the treatment of MCL; unfortunately, MRD is not effectively eliminated by subsequent CHOP chemotherapy. We are planning to explore chemotherapy induction followed by RIT. [Table: see text]

Introduction. Mantle cell lymphoma is a rare type of B-cell non-Hodgkin lymphoma. According to statistics the incidence of this disorder amounts to 2-3 per 100,000 people; this is about 6% of all non-Hodgkin lymphomas. It has been established that various molecular genetic characteristics of mantle cell lymphoma patients may present opportunities for a patient-specific approach to the disease prognosis and treatment strategy.Materials and methods. The paper presents a retrospective analysis of 45 mantle cell lymphoma patients treated at the GAUZ RKOD of the Ministry of Healthcare from 2015 until now. The data used in the analysis included clinical examination, lab panels, PET CT, tumour and bone marrow biopsy specimen cytology, histology and immunohistochemistry. We analysed the epidemiological data, the patients’ clinical presentation characteristics, treatment approaches, immediate and long-term outcomes.Results and discussion. We have established that the pathological process most frequently involves bone marrow (44%) and spleen (41%). The MIPI scores distribution was as follows: high in 14 (30%), medium in 20 (45%), low in 11 (41%). Ki67 was recorded at under 30% in four cases, in others it amounted to over 30%. In 2015–2017 patients were treated with the R-CHOP protocol with the following support with rituximab. PFS averaged at 20 months, 8 (17%) of patients remain in lasting remission (since 2015). In 2017 the R-BAC (high dose cytarabine for SCT candidates) and R-B (for the elderly and comorbid patients) became protocols of first line. Since 2018 eight patients have undergone auto-SCT (at the first late recurrence) as a treatment consolidation stage. As of now 13 patients have been examined in federal centres for del17p and the TP53 mutation.Conclusion. We have demonstrated the need for and the option of treatment depending on the results of molecular genetic testing of mantle cell lymphomas.
