Purpose: To assess the safety and efficacy of intensive methotrexate-based chemotherapy followed by high-dose chemotherapy (HDT) with autologous stem-cell rescue in patients with newly diagnosed primary CNS lymphoma (PCNSL). Patients and Methods: Twenty-eight patients received induction chemotherapy using high-dose systemic methotrexate (3.5 g/m2) and cytarabine (3 g/m2 daily for 2 days). Fourteen patients with chemosensitive disease evident on neuroimaging then received high-dose therapy using carmustine, etoposide, cytarabine, and melphalan with autologous stem-cell rescue. Results: The objective response rate to the induction-phase chemotherapy was 57%, and median overall survival is not yet assessable, with a median follow-up time of 28 months. The overall median event-free survival time is 5.6 months for all patients and 9.3 months for 14 patients who underwent transplantation. Six of these 14 patients (43%) remained disease-free at last follow-up. Treatment was well tolerated; there was one transplantation-related death. Prospective neuropsychologic evaluations have revealed no evidence of treatment-related neurotoxicity. Conclusion: This treatment approach is feasible in patients with newly diagnosed PCNSL without evidence of significant related neurotoxicity. Although the transplantation results are similar to those achieved in patients with aggressive or poor-prognosis systemic lymphoma, the low response rate to induction chemotherapy and the significant number of patients who experienced relapse soon after HDT suggest that more aggressive induction chemotherapy may be warranted.

Abstract Introduction: High-dose chemotherapy (HDT) and autologous stem-cell transplantation (ASCT) demonstrated high efficacy in the treatment of newly-diagnosed primary CNS lymphoma (PCNSL) in younger patients (pts.). A 5-year overall survival probability (OS) of 69% could be demonstrated in 30 pts within a phase-II trial on HDT and ASCT with consolidating whole-brain-irradiation (WBRT) (Illerhaus et al. JCO 2006). A subsequent pilot trial on HDT and ASCT without WBRT showed a 5-year OS of 77% (Illerhaus et al. Haematologica 2008). Here we give an update of our two different treatment regimens and future perspectives. Patients and Methods: Thirty pts. ≤65 years were treated within the phase II trial, chemotherapy (CHT) consisted of 3 cycles of high-dose methotrexate (MTX, 8 g/m2), 1 cycle of AraC (2× 3 g/m2) plus thiotepa (TT, 40 mg/m2) followed by rG-CSF and stem-cell-mobilization. Conditioning regimen included BCNU (400 mg/m2) and TT (2×5 mg/kgBW) followed by ASCT. Hyperfractionated WBRT (45 Gy, 2×1Gy/d) was administered as consolidation. In our subsequent pilot trial 13 pts. (age 38–67 years) were treated without consolidating WBRT; CHT was intensified with 4 cycles MTX 8g/m2, 2 cycles AraC (2× 3 g/m2) and TT (40 mg/m2). Dose escalated HDT included BCNU (400 mg/m2) and TT (4×5 mg/kgBW) followed by ASCT. WBRT was reserved for pts. not responding to CHT. Results: Median follow-up of the 30 pts. treated within our phase II trial was extended to 95 months (mo), the updated 5-year OS of all pts. is 66.6% and 82,3% of the subgroup of pts. who underwent HDT and ASCT (n=23), respectively. Three additional deaths occurred due to relapse (n=2) after 45 and 71 mo and due to comorbidity (n=1) after 103 mo. Five of 30 pts. developed severe leukoencephalopathy during follow-up. With a median follow-up of 35 mo in the 13 pts. treated within the pilot-phase without consolidating WBRT 3-year OS of all pts. is 77%. No further relapse or non-relapse mortality occurred in this pilot-group during. Most recent follow-up data will be presented in detail. Conclusion: Sequential systemic application of high-dose cytostatic agents followed by HDT+ASCT is highly effective as initial therapy for pts. with PCNSL. The restriction of WBRT to refractory disease shows similar OS rates and a decrease in neurotoxicity. In an ongoing multicenter phase-II trial immunotherapy with rituximab is combined with HDT and ASCT to further increase remission rates. A future randomized trial should be focused on the efficacy of consolidation with HDT supported by ASCT.

Induction Regimen

2008 Background: In our previous study in newly diagnosed PCNSL, induction chemotherapy with MTX and cytarabine followed by consolidation HDC (carmustine, etoposide, cytarabine, melphalan [BEAM]) with ASCT without radiotherapy resulted in only 50% of pts transplanted, reflecting low efficacy of induction chemotherapy, and short intent-to-treat (ITT) median PFS (=6m). In this phase II trial, we sought to optimize this strategy by utilizing a more effective induction regimen (R-MPV) and a more aggressive HDC regimen (Soussain et al). Methods: Pts received 5-7 cycles of R-MPV (MTX: 3.5g/m2) and if a partial or complete response was achieved, HDC with thiothepa, cyclophosphamide and busulfan was given, followed by ASCT and no radiotherapy. The primary endpoint was ITT 1 year event-free survival (promising: 75%, non-promising: 50%; 90% power, significance=0.05). Follow-up included comprehensive neuropsychological evaluation. Results: Accrual has been completed (N=32 pts, median age 57 [range 23-67], median KPS=80). Following R-MPV, 17 pts achieved a CR, 13 pts a PR and two pts progressed. A total of 25 (78%) pts were transplanted; the reasons for not receiving transplant were progressive disease (N=2), poor performance status/ physician’s decision (N= 2), mobilization failure (N=1) and consent withdrawn (N= 2). One pt who withdrew consent relapsed and received HDCASCT for salvage. Two (8%) pts died from early complications of ASCT (Stevens-Johnson: one, sepsis: one) and one pt experienced a fatal late colitis of unknown etiology. In the ITT population, the median EFS and OS have not been reached after a median follow-up of 22 months. The 1 year EFS was 78% (95%CI 58-90) and the 2y OS was 76% (95% CI 54-89). No pt has developed delayed neurotoxicity. Conclusions: R-MPV induction regimen resulted in improved response rates, allowing 78% of pts to receive HDC-ASCT. Although more toxic, this regimen resulted in excellent disease control and survival in the ITT population, far exceeding the efficacy of our previous transplant study. The primary endpoint was met, warranting further investigation.

Purpose: We evaluated the usefulness of a treatment regimen that included high-dose chemotherapy (HDC) with autologous stem-cell rescue (ASCR) in patients with newly diagnosed pineoblastoma (PBL). Patients and Methods: Twelve patients with PBL were initially treated with surgery and induction chemotherapy. All but two patients underwent radiotherapy. Subsequently, all patients received HDC using cyclophosphamide (CTX) + melphalan (MEL) or busulfan (Bu) + MEL regimens and ASCR. Results: A total of six children and six adults with median ages of 4.2 (range, 0.3 to 19.8 years) and 23 years (range, 23 to 43.7 years), respectively, were treated according to this strategy. Four patients had metastatic disease confined to the neuraxis. Five of 12 patients (42%) had a complete tumor resection at diagnosis. Ten patients received radiotherapy at median doses of 36.0 and 59.4 Gy to the neuraxis and pineal region, respectively. Eleven patients received HDC with CTX + MEL, and one patient received BU + MEL followed by ASCR. Nine patients are alive with no evidence of disease recurrence at a median of 62 months from diagnosis (range, 28 to 125 months), including three patients with metastatic disease and two infants who did not receive any radiotherapy. Three patients have died of progressive disease at 19, 32, and 37 months from diagnosis, respectively. The actuarial 4-year progression-free and overall survivals are 69% (95% confidence interval [CI], 39% to 99%) and 71% (95% CI, 43% to 99%), respectively. Conclusion: The use of HDC in addition to radiotherapy seems to be an effective treatment for patients with newly diagnosed pineoblastoma.

Abstract Intravascular lymphoma is a rare subtype of extranodal DLBCL characterized by the proliferation of malignant B-cells within the lumina of blood vessels. Organ involvement is variable and diffuse. Making the diagnosis can be challenging with symptoms persisting for months prior to definitive diagnosis. Treatment to date with standard anthracycline containing chemotherapy regimens has been disappointing with variable response rates, high relapse rates, and median survival times typically measured in months. We report diagnostic, treatment, and follow-up information regarding a group of patients with intravascular lymphoma evaluated at the Mayo Clinic with special attention to those receiving rituximab and/or high dose chemotherapy with or without peripheral blood autologous stem cell rescue. Methods: The medical records of patients with intravascular lymphoma seen at the Mayo Clinic between January 1970 and May 2005 were reviewed. Patients were included if they had evidence of intravascular lymphoma at the time of diagnosis of lymphoma. Pathologic specimens were reviewed for confirmation of diagnosis. Results: Twenty patients with a diagnosis of intravascular lymphoma were identified. Their median age was 66.5 years. Thirteen (65%) had B symptoms at the time of diagnosis and 13 had a performance status ≥ 3. Nine (45%) had an IPI ≥ 4. The median time to diagnosis from the onset of symptoms was 5.5 months. All had stage IV disease with biopsy proven involvement of at least one organ. The sites of disease involvement were CNS (10), marrow (7), lung (5), adrenal (3), kidney (2), lymph node, seminal vesicle, and skin (1). Two patients had involvement of three organs, six had involvement of two organs, and twelve had involvement of one organ. Nineteen patients received chemotherapy: ProMACE/CytaBOM (3), CHOP (6), RCHOP (6), DHAP (1), high dose methotrexate (1), methylprednisolone, nitrogen mustard, rituximab (1), and hyperCVAD (1). Three patients underwent peripheral blood autologous stem cell rescue after conditioning with BEAM. With a median follow-up of 60 months for all patients, the median overall survival was 8 months. No difference in outcome was seen with regard to site of organ involvement, number of organs involved, presence of B symptoms, or IPI. With a median follow-up for those receiving rituximab of 26 months, the median survival has not yet been reached while the median survival for those receiving non-rituximab containing regimens was 6.5 months. Similarly, with a median follow-up for those receiving high dose chemotherapy (hyperCVAD or BEAM) of 9.3 months, the median survival has not yet been reached while the median survival for those not receiving high dose therapy was 7 months. Conclusion: Intravascular lymphoma is a unique and aggressive subtype of DLBCL. The clinical presentation and sites of organ involvement are variable and the time from onset of symptoms to diagnosis can be prolonged. Standard chemotherapeutic treatment leads to poor outcomes. However, survival may be improved upon with newer strategies such as the use of rituximab and/or high dose chemotherapy with or without peripheral blood autologous stem cell rescue.
