ABSTRACT: Few randomized trials have compared therapies in mantle cell lymphoma (MCL), and the role of aggressive induction is unclear. The National Comprehensive Cancer Network (NCCN) Non-Hodgkin Lymphoma (NHL) Database, a prospective cohort study collecting clinical, treatment, and outcome data at 7 NCCN centers, provides a unique opportunity to compare the effectiveness of initial therapies in MCL. Patients younger than 65 diagnosed between 2000 and 2008 were included if they received RHCVAD (rituximab fractionated cyclophosphamide, vincristine, adriamycin, and dexamethasone), RCHOP+HDT/ASCR (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone + high-dose therapy/autologous stem cell rescue), RHCVAD+HDT/ASCR, or RCHOP. Clinical parameters were similar for patients treated with RHCVAD (n = 83, 50%), RCHOP+HDT/ASCR (n = 34, 20%), RCHOP (n = 29, 17%), or RHCVAD+HDT/ASCR (n = 21, 13%). Overall, 70 (42%) of the 167 patients progressed and 25 (15%) expired with a median follow-up of 33 months. There was no difference in progression-free survival (PFS) between aggressive regimens (P > .57), which all demonstrated superior PFS compared with RCHOP (P < .004). There was no difference in overall survival (OS) between the RHCVAD and RCHOP+HDT/ASCR (P = .98). RCHOP was inferior to RHCVAD and RCHOP+HDT/ASCR, which had similar PFS and OS. Despite aggressive regimens, the median PFS was 3 to 4 years. Future trials should focus on novel agents rather than comparing current approaches.

ABSTRACT: We aimed to characterize surveillance imaging and circumstances of relapse for patients with diffuse large B-cell lymphoma (DLBCL) in the National Comprehensive Cancer Network Non-Hodgkin's Lymphoma Outcomes Database, a prospective cohort study collecting clinical and outcome data at seven comprehensive cancer centers. Patients presenting with newly diagnosed DLBCL in remission ≥3 months after initial therapy and who had accrued 2 years of follow-up were eligible for analysis (n = 625). The median number of imaging studies was 2.5/year (institutional range 0.5-3.5, p < 0.0001); 48.4% received only dedicated computed tomography (CT) scans, 14.6% received only positron emission tomography (PET)-inclusive modalities, 32.8% received a combination and 4.2% received no imaging. Among all eligible patients, 50 (8.0%) experienced relapse, and approximately one-quarter of subclinical relapses were detected through routine imaging. Our results suggest that despite limited data regarding its effect on outcomes, surveillance imaging is prevalent in DLBCL, and a majority of patients receive PET scans at some point during follow-up.

ABSTRACT: Little is known about the utility of central nervous system (CNS) prophylaxis for diffuse large B-cell lymphoma (DLBCL) in the rituximab era. The objective of this study was to characterize patterns of CNS prophylaxis for patients who received combined rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy using the National Comprehensive Cancer Network Non-Hodgkin Lymphoma Outcomes Database, a prospective cohort study that collects clinical and outcomes data for patients at 7 participating centers.
Patients who were eligible for this analysis presented with newly diagnosed DLBCL between January 2001 and July 2008, had no evidence of baseline CNS disease, and had received R-CHOP within 180 days of diagnosis. The authors assessed incidence and covariates of prophylaxis, prophylaxis modality, and, using propensity score analysis, outcomes such as overall survival.
Of 989 eligible patients, 117 received CNS prophylaxis (11.8%), most intrathecally (71.8%). Involvement of bone marrow, other high-risk site, >1 extranodal site, higher International Prognostic Index score, and higher stage were associated individually with the receipt of prophylaxis (all P < .0001). At a median follow-up of 2.5 years, there were 20 CNS recurrences (2% [95% confidence interval, 1.1%-2.9%]) among all patients, and overall survival was not affected by prophylaxis.
Given the overall low rate of CNS recurrence and lack of prophylaxis-associated survival benefit, the current data called into question the practice of CNS prophylaxis in the rituximab era.
