Title: Accelerated Total Lymphoid Irradiation-containing Salvage Regimen for Patients With Refractory and Relapsed Hodgkin Lymphoma: 20 Years of Experience

Abstract

Purpose: We report the long-term results of integrated accelerated involved field radiation therapy (IFRT) followed by total lymphoid irradiation (TLI) as part of the high-dose salvage regimen followed by autologous bone marrow transplantation or autologous stem cell transplantation in patients with relapsed or refractory Hodgkin lymphoma (HL). Methods and Materials: From November 1985 to July 2008, 186 previously unirradiated patients with relapsed or refractory HL underwent salvage therapy on 4 consecutive institutional review board–approved protocols. All patients had biopsy-proven primary refractory or relapsed HL. After standard-dose salvage chemotherapy (SC), accelerated IFRT (18-20 Gy) was given to relapsed or refractory sites, followed by TLI (15-18 Gy) and high-dose chemotherapy. Overall survival (OS) and event-free survival (EFS) were analyzed by Cox analysis and disease-specific survival (DSS) by competing-risk regression. Results: With a median follow-up period of 57 months among survivors, 5- and 10-year OS rates were 68% and 56%, respectively; 5- and 10-year EFS rates were 62% and 56%, respectively; and 5- and 10-year cumulative incidences of HL-related deaths were 21% and 29%, respectively. On multivariate analysis, complete response to SC was independently associated with improved OS and EFS. Primary refractory disease and extranodal disease were independently associated with poor DSS. Eight patients had grademore » 3 or higher cardiac toxicity, with 3 deaths. Second malignancies developed in 10 patients, 5 of whom died. Conclusions: Accelerated IFRT followed by TLI and high-dose chemotherapy is an effective, feasible, and safe salvage strategy for patients with relapsed or refractory HL with excellent long-term OS, EFS, and DSS. Complete response to SC is the most important prognostic factor.« less

  • Purpose: To analyze, through chart review, the efficacy of salvage radiation therapy (sRT) for relapsed or progressive Hodgkin lymphoma (HL) patients who failed autologous stem cell transplant (ASCT). Patients and Methods: Among 347 patients with recurrent/refractory HL who received ASCT from 1986-2006, 163 had post-ASCT progression or relapse. Of these, 56 received sRT and form the basis of this report. Median age at sRT was 30 years (range, 17-59 years). Disease was confined to lymph nodes in 27 patients, whereas 24 had both nodal and extranodal disease. Salvage radiation therapy alone was given in 34 patients (61%), and sRT plusmore » chemotherapy was given in 22 (39%). Median interval from ASCT to sRT was 0.8 years (range, 0.1-5.6 years). The median dose was 35 Gy (range, 8-40.3 Gy). The sRT technique was extended-field in 14 patients (25%) and involved-field in 42 (75%). Results: The median follow-up from sRT was 31.3 months (range, 0.2-205.5 months). Overall response rate was 84% (complete response: 36%; partial response: 48%). The median overall survival was 40.8 months (95% confidence interval, 34.2-56.3 months). The 5-year overall survival was 29% (95% confidence interval, 14%-44%). The 2-year progression-free survival (PFS) was 16%; the 2-year local PFS was 65%, whereas the 2-year systemic PFS was 17%. The 1-year PFS was higher in patients in whom all diseased sites were irradiated (49%) compared with those in whom only the symptomatic site was treated (22%, P=.07). Among 20 alive patients, 5 were disease free (at 6.4, 6.8, 7.4, 7.9, and 17.1 years). Conclusion: For patients with HL who fail ASCT, a selective use of RT provides a durable local control rate of 65% at 2 years and should be considered as part of the standard management plan for the palliation of incurable HL. Occasionally irradiation of truly localized disease can lead to long-term survival.« less
  • Purpose: To evaluate the response rate (RR) and time to local recurrence (TTLR) among patients who received salvage radiation therapy for relapsed or refractory aggressive non-Hodgkin lymphoma (NHL) and investigate whether RR and TTLR differed according to disease characteristics. Methods and Materials: A retrospective review was performed for all patients who completed a course of salvage radiation therapy between January 2001 and May 2011 at Brigham and Women's Hospital/Dana-Farber Cancer Institute. Separate analyses were conducted for patients treated with palliative and curative intent. Predictors of RR for each subgroup were assessed using a generalized estimating equation model. For patients treatedmore » with curative intent, local control (LC) and progression-free survival were estimated with the Kaplan-Meier method; predictors for TTLR were evaluated using a Cox proportional hazards regression model. Results: Salvage radiation therapy was used to treat 110 patients to 121 sites (76 curative, 45 palliative). Salvage radiation therapy was given as part of consolidation in 18% of patients treated with curative intent. Median dose was 37.8 Gy, with 58% and 36% of curative and palliative patients, respectively, receiving 39.6 Gy or higher. The RR was high (86% curative, 84% palliative). With a median follow-up of 4.8 years among living patients, 5-year LC and progression-free survival for curative patients were 66% and 34%, respectively. Refractory disease (hazard ratio 3.3; P=.024) and lack of response to initial chemotherapy (hazard ratio 4.3; P=.007) but not dose (P=.93) were associated with shorter TTLR. Despite doses of 39.6 Gy or higher, 2-year LC was only 61% for definitive patients with refractory disease or disease that did not respond to initial chemotherapy. Conclusions: Relapsed or refractory aggressive NHL is responsive to salvage radiation therapy, and durable LC can be achieved in some cases. However, refractory disease is associated with a shorter TTLR, suggesting that radiation dose escalation, addition of radiosensitizers, or a combination of both may be indicated in these patients.« less
  • Purpose: To evaluate the value of adding involved field radiotherapy (IFRT) to patients with relapsed/refractory Hodgkin lymphoma (HL) undergoing high-dose chemotherapy (HDCT) and stem cell transplantation (SCT). Methods and Materials: Ninety-two patients with relapsed/refractory HL undergoing HDCT and SCT from 1995 to 2008 were analyzed in a case-control design. Forty-six HL patients treated with IFRT within 2 months of SCT were matched to 46 HL patients who did not receive IFRT based on age, stage at relapse, timing of relapse, histology, and year of SCT. All were evaluated for response, survival, and toxicity with a median followup of 63.5 months.more » Results: There was a trend for better disease control in patients receiving IFRT. Specifically, 10/46 IFRT patients (22%) relapsed/progressed after SCT compared with 17/46 control patients (37%). Of the failures after IFRT, 70% were inside the radiation field, all in sites of bulky disease. In patients with nonbulky disease, IFRT also resulted in significantly improved outcomes (failure rate 6% vs. 33%, respectively). When stratified by disease bulk, the use of IFRT was found to significantly improve DFS (p = 0.032), but did not affect OS. In addition, IFRT and nonbulky disease were found to be positive prognostic indicators for DFS with hazard ratios of 0.357 (p = 0.032) and 0.383 (p = 0.034), respectively. Grade IV/V toxicities were significantly higher in the IFRT vs. non-IFRT group (28% vs. 2%; p < 0.001), observed only in patients receiving a busulfan-based conditioning regimen. Conclusion: Patients with refractory or relapsed HL undergoing HDCT and SCT have a high risk of relapse in sites of prior disease involvement, especially in sites of bulky disease. The use of IFRT is associated with a lower risk of disease progression in these sites; however bulky disease sites are still difficult to control. Toxicity risk is significant, particularly when busulfan-based conditioning is combined with IFRT, and alternative chemotherapy conditioning regimens should be considered.« less
  • Purpose: To evaluate the clinical outcome of salvage treatment for patients with relapsed natural killer (NK)/T-cell lymphoma, nasal type. Methods and Materials: Forty-four patients who had achieved complete response during initial treatment and experienced histologically proven relapse were reviewed. Twenty-nine of them received salvage treatment with radiotherapy (RT) alone (n = 7), chemotherapy (CT) alone (n = 10), or both RT and CT (n = 12); the other 15 patients received best supportive care alone. Results: The estimated 5-year overall survival (OS) rate for patients with or without salvage treatment was 37.8% vs. 0 (p < 0.0001), respectively. Salvage CTmore » did not improve survival of relapsed Stage IE and IIE patients. Among relapsed Stage IIIE and IVE patients who received salvage treatment, RT developed significantly better survival when compared with that of non-RT (1-year OS, 62.5% vs. 0, p = 0.006). Relapsed Ann Arbor stage and receiving salvage treatment were found to be significant factors influencing OS at both univariate and multivariate levels. Conclusions: Salvage treatment improved survival in patients with relapsed NK/T-cell lymphoma, nasal type. Salvage RT may play an important role in salvage treatment of relapsed extranodal NK/T-cell lymphoma.« less
  • Purpose: The majority of patients with relapsed or refractory B-cell, non-Hodgkin’s lymphoma (NHL) are over 60 years of age, yet they are often denied potentially curative high-dose therapy and autologous stem cell transplants (ASCT) due to the risk of excessive treatment-related morbidity and mortality. Myeloablative anti-CD20 radioimmunotherapy (RIT) can deliver curative radiation doses to tumor sites while limiting exposure to normal organs and may be particularly suited for older adults requiring high-dose therapy. Methods: Patients over age 60 with relapsed B-NHL received infusions of tositumomab anti-CD20 antibody labeled with 5-10mCi I-131 tracer for dosimetry purposes followed 10 days later bymore » individualized therapeutic infusions of I-131-tositumomab (median 525 mCi, range 328-1154 mCi) to deliver 25-27Gy to the critical normal organ receiving the highest radiation dose. ASCT was performed approximately 2 weeks after therapy. Results: Twenty-four patients with a median age of 64 (range 60-76) who had received a median of four prior regimens (range 2-14) were treated. Thirteen (54%) had chemotherapy-resistant disease. The estimated 3-year overall and progression-free survivals were 59% and 51%, respectively with a median follow-up of 2.9 years (range 1-6 years). All patients experienced expected myeloablation with engraftment of platelets (≥20K/µL) and neutrophils (≥500/µL) occurring a median of 9 and 15 days, respectively following ASCT. There were no treatment-related deaths, and only two patients experienced grade 4 non-hematologic toxicity. Conclusions: Myeloablative RIT and ASCT is a safe and effective therapeutic option for older adults with relapsed B-NHL.« less
