Improved Progression-Free Survival for Bulky and Non-Bulky Advanced Stage Diffuse Large B-Cell Lymphoma With Consolidative Radiation Therapy: A Bi-Institutional Analysis

PURPOSE Immunochemotherapy with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) has become standard of care for patients with diffuse large B-cell lymphoma (DLBCL). This randomized trial assessed whether rituximab intensification during the first 4 cycles of R-CHOP could improve the outcome of these patients compared with standard R-CHOP. PATIENTS AND METHODS A total of 574 patients with DLBCL age 18 to 80 years were randomly assigned to induction therapy with 6 or 8 cycles of R-CHOP-14 with (RR-CHOP-14) or without (R-CHOP-14) intensification of rituximab in the first 4 cycles. The primary end point was complete remission (CR) on induction. Analyses were performed by intention to treat. RESULTS CR was achieved in 254 (89%) of 286 patients in the R-CHOP-14 arm and 249 (86%) of 288 patients in the RR-CHOP-14 arm (hazard ratio [HR], 0.82; 95% CI, 0.50 to 1.36; P = .44). After a median follow-up of 92 months (range, 1-131 months), 3-year failure-free survival was 74% (95% CI, 68% to 78%) in the R-CHOP-14 arm versus 69% (95% CI, 63% to 74%) in the RR-CHOP-14 arm (HR, 1.26; 95% CI, 0.98 to 1.61; P = .07). Progression-free survival at 3 years was 74% (95% CI, 69% to 79%) in the R-CHOP-14 arm versus 71% (95% CI, 66% to 76%) in the RR-CHOP-14 arm (HR, 1.20; 95% CI, 0.94 to 1.55; P = .15). Overall survival at 3 years was 81% (95% CI, 76% to 85%) in the R-CHOP-14 arm versus 76% (95% CI, 70% to 80%) in the RR-CHOP-14 arm (HR, 1.27; 95% CI, 0.97 to 1.67; P = .09). Patients between ages 66 and 80 years experienced significantly more toxicity during the first 4 cycles in the RR-CHOP-14 arm, especially neutropenia and infections. CONCLUSION Early rituximab intensification during R-CHOP-14 does not improve outcome in patients with untreated DLBCL.

Aim: To describe practices and outcomes in veterans with relapsed/refractory diffuse large B-cell lymphoma. Patients & methods: Using Veteran Affairs Cancer Registry System and electronic health record data, we identified relapsed/refractory diffuse large B-cell lymphoma patients completing second-line treatment (2L) in 2000–2016. Treatments were classified as aggressive/nonaggressive. Analyses included descriptive statistics and the Kaplan–Meier estimation of progression-free survival and overall survival. Results: Two hundred and seventy patients received 2L. During median 9.7-month follow-up starting from 2L, 470 regimens were observed, averaging 2.7 regimens/patient: 219 aggressive, 251 nonaggressive. One hundred and twenty-one patients proceeded to third-line, 50 to fourth-line and 18 to fifth-line treatment. Median progression-free survival in 2L was 5.2 months. Median overall survival was 9.5 months. Forty-four patients (16.3%) proceeded to bone marrow transplant. Conclusion: More effective, less toxic treatments are needed and should be initiated earlier in treatment trajectory.

Abstract Background: Peripheral T-cell lymphomas (PTCL) represent a heterogeneous group of diseases with an overall poor prognosis. Little information is available regarding the outcome of PTCL patients who present with limited stage disease. We sought to determine the outcome of PTCL patients presenting with limited disease in comparison with a cohort of patients with limited stage diffuse large B-cell lymphoma (DLBCL). Methods: In a retrospective analysis we identified all patients with limited stage (non-bulky (<10cm) stage I/II disease no symptoms) PTCL diagnosed at the British Columbia Cancer Agency (BCCA) between 1983 and 2004. Patients were excluded if they had cutaneous anaplastic large cell lymphoma (CutALCL) (n=13), NK/T-cell lymphoma nasal type (n=9) or primary CNS/ocular involvement (n=6). Results: Thirty-seven patients with PTCL were identified according to the World Health Organization Classification: ALK-neg ALCL 8 (22%); PTCL-unspecified (PTCLUS) 28 (78%); enteropathy associated TCL (EATL) 1 (3 %). The majority received CHOP-type chemotherapy (n=31, 86%), most with brief chemotherapy followed by involved-field radiation (n=19, 61%). The 5 y OS and PFS was similar between PTCLUS and ALK-neg ALCL. There was no difference in survival between extranodal and nodal cases. The outcome of PTCL patients (including ALK-neg ALCL and PTCLUS) was compared to a cohort of limited stage DLBCL patients (excluding CNS/ocular lymphoma) (n=305) diagnosed over the same time period and treated similarly. There was no difference in 5 y OS or PFS (Figure 1,2). Interestingly, there were no late relapses observed in PTCLUS, in marked contrast to DLBCL. Conclusions: Limited stage PTCL is rare, however outcomes appear to be comparable to early stage DLBCL, supporting that they should be treated in a similar manner. Unlike limited stage DLBCL where late relapses occur, a plateau in the progression-free survival curve is observed, highlighting a distinct natural history for limited stage PTCL.

Abstract Rearrangements of the c-myc oncogene can be seen in 5–10% of patients with diffuse large B-cell lymphoma. However, studies examining the significance of this finding have yielded conflicting results. Therefore, we performed a retrospective analysis to determine the clinical significance of c-myc rearrangements in diffuse large B-cell lymphoma. The results of classical cytogenetic studies and FISH analyses were used to identify diffuse large B-cell lymphoma cases in the database of the Nebraska Lymphoma Study Group with or without c-myc rearrangements. Patients who were HIV positive and those with post-transplant lymphoproliferative disease were excluded. We identified 16 patients with diffuse large B-cell lymphoma and c-myc rearrangements. All patients were initially treated with doxorubicin- or mitoxantrone-containing chemotherapy regimens. The median age of these 16 patients was 61 years (range 40 to 80), and 5 (31%) were males. The International Prognostic Index (IPI) was 0–2 at diagnosis in 9 patients (56%), and 3–5 in 7 patients (44%). Eleven patients (69%) had bulky disease (≥ 5 cm) at diagnosis. No significant differences in outcome were identified when the 16 c-myc positive patients were compared with 97 c-myc negative diffuse large B-cell lymphoma patients in the same age range. The actuarial 5-year progression-free survival for the c-myc positive patients was 23% (95% CI 6% to 46%), as compared with 38% (95% CI 29% to 48%) for c-myc negative patients (p=0.17). The actuarial 5-year overall survival rates were 36% (95% CI 14% to 59%) and 47% (95% CI 36% to 56%), respectively (p=0.19). Classical cytogenetics and FISH analyses were also used to examine the 16 c-myc positive cases for bcl-2 rearrangements. Eight (50%) cases had rearrangements of bcl-2 in addition to c-myc rearrangements. These patients were similar to the c-myc positive/bcl-2 negative patients except for a higher likelihood of an elevated LDH level at diagnosis (88% vs. 25%; p=0.03). The actuarial 5-year progression-free survival for c-myc positive/bcl-2 positive patients was 0%, as compared to 33% (95% CI 6% to 66%) for patients with rearrangements of c-myc alone, and 37% (95% CI 28% to 47%) for c-myc negative patients. The actuarial 5-year overall survival rates were 12% (95% CI 1% to 42%), 47% (95% CI 12% to 76%), and 41% (95% CI 31% to 51%), respectively. A multivariate analysis, adjusting for IPI score, demonstrated that the relative risk (RR) of treatment failure was significantly worse for the c-myc positive/bcl-2 positive patients, as compared to the c-myc negative patients (RR 2.86, 95% CI 1.32–6.23; p=0.008). Similarly, mortality was also significantly worse for the c-myc positive/bcl-2 positive patients, as compared to the c-myc negative patients (RR 2.69, 95% CI 1.18–6.11; p=0.02). In contrast, no significant differences in treatment failure or overall survival were demonstrated when c-myc positive/bcl-2 negative patients were compared with c-myc negative patients. Our results demonstrate that the c-myc rearrangement is not associated with poorer survival in patients with diffuse large B-cell lymphoma. However, patients with rearrangements of bcl-2 in addition to c-myc had significantly worse progression-free survival and overall survival.

Abstract INTRODUCTION: Non-mycosis fungoides (MF) primary cutaneous lymphoma (PCL) is rare, and the more indolent forms seldom progress to fatal, systemic lymphoma. Nevertheless, frequent relapses are common. Although several therapies exist, no standard of care has been established for initial treatment. OBJECTIVES: To compare the role of radiotherapy to other initial treatment options and to evaluate clinicopathologic factors affecting overall, cause-specific, and relapse-free survival METHODS: Thirty-eight patients from 1985 to 2006 were retrospectively identified and reviewed with non-MF PCLs including: primary cutaneous anaplastic large cell lymphoma, subcutaneous panniculitis-like T-cell lymphoma, primary cutaneous marginal zone B-cell lymphoma, primary cutaneous follicle-center lymphoma, primary cutaneous diffuse large B-cell lymphoma, leg type, or primary cutaneous intravascular large B-cell lymphoma. Regression-free, cause-specific, and overall survival was estimated using the methods of Kaplan and Meier. Outcomes were compared with the log-rank test and Cox regression analysis. RESULTS: 38 patients were included in the analysis with a median follow-up time of 34.6 months (range 2 – 138 months). The distribution of initial treatment was: surgery - 29%, topical therapy - 16%, systemic therapy - 18%, and radiation - 63%. Three patients never received radiation. For the entire cohort, the 5-year overall (OS), cause-specific (CSS), and relapse free survival (RFS) was 86.2%, 88.9%, and 29.5% respectively. Subjects who received radiation therapy (n=24) as part of their initial treatment course had a significantly longer median time to first relapse of 57 months compared to 3.2 months for the 14 subjects who did not receive radiotherapy (log-rank p < 0.0001). Overall survival was significantly improved for subjects whose International Prognostic Index (IPI) score was 0–1 (n=25) versus those whose score was 2 or greater (n=13, p=0.05). Multivariate analysis for RFS revealed that the absence of radiation as part of initial treatment (Hazard Ratio (HR) = 22.2, 95% CI 2.1 – 238.5, p=0.01) and aggregate size less than 10cm (HR 0.04, 95% CI 0.0 – 0.3, p<0.01) significantly altered the risk of relapse. No relapses were observed within the radiation therapy treatment field in 31/35 (89%) subjects following their first course of radiation therapy. Of the 15/35 (43%) of patients that relapsed anywhere following radiation, only 2/15 (13%) relapsed in-field exclusively, 2/15 (13%) relapsed both in and out-of-field, and the remaining 11/15 (73%) relapsed exclusively outside the area treated. No patient relapsed within the treatment field of after 24 months. CONCLUSION: An initial course of radiation therapy significantly delays relapse compared to other therapies for non-MF PCL and provides excellent local control of plaques. Our findings also extend the IPI as prognostic for overall survival for this rare disease. Bulky lesions greater than 10cm in any one dimension are more strongly correlated with relapse.

Abstract Abstract 2676 Purpose Akt is a serine/threonine kinase that plays a central role in cell proliferation and growth. To define clinical impact of Akt expression in diffuse large B-cell lymphoma(DLBCL), we investigated the expression of phospho-Akt(p-Akt) in DLBCL and analyzed clinical impact of p-Akt expression on patient survival. Methods We evaluated the p-Akt expression in 99 DLBCL patients using tissue microarray(TMA) technology. Results Positive p-Akt expression was observed in 15.2% of the patients and significantly associated with elevated lactic dehydrogenase level (P = .044). Kaplan-Meier survival analysis showed that the patients with positive p-Akt expression showed substantially poorer overall survival (p-Akt+ vs p-Akt- 25.3 months [95% confidence interval(CI), 14.4–36.2 months] vs 192.6 months [95% CI, 131.3–253.9 months], P < .001) and progression-free survival (p-Akt+ vs p-Akt- 13.6 months[95% CI, 14.4–36.2 months] vs 134.5 months [95% CI, 131.3–253.9 months], P < .001), respectively. Multivariate Cox regression analysis revealed that patients with DLBCL with p-Akt positivity showed poorer overall survival with 3.2 fold (95% CI, 1.6–6.8, P = .002) risk for death compared to patients with DLBCL with p-Akt negativity. Conclusion Positive expression of p-Akt in DLBCL patients is associated with poorer overall and progression-free survival. Expression of p-Akt may act as an independent poor prognostic factor and might be a novel therapeutic target for DLBCL. Disclosures: No relevant conflicts of interest to declare.
