RESUMO
Background: Management of adolescent and young adults (AYAs) cancer is very heterogeneous. In the case of lymphomas, outcomes are mostly favorable but there is still room for improvement. Design: We retrospectively collected the pattern of care of all institutional 13- to 25-year-old AYAs patients with classical Hodgkin lymphoma (HL) or non-Hodgkin lymphoma (NHL) diagnosed in the Rhône-Alpes region between the years 2000 and 2005. Management, including adherence to Clinical Practice Guidelines (CPGs), and long-term survival were analyzed by comparing adult units (AU) and pediatric units (PU). Results: 278 patients were included: 198 treated for HL (median age of 19 years), 80 treated for NHL (median age of 20 years). Among them, 74% were managed in AU and 26% in PU. The median time between diagnosis and starting treatment was significantly lower in PU than in AU. Sixty-five patients (23%) were included in clinical trials, mostly in AU. Five-year overall survival was 96% for HL [14 deaths, median follow-up 91 months (9-180)] and 90% for NHL [nine deaths, median follow-up 80 months (3-180)]. Secondary cancers occurred for 2% (n = 3) of HL patients and for none in NHL. Other major late complications included cardiovascular accidents in two patients and fatal pulmonary fibrosis in one patient. Major differences in chemotherapy and radiotherapy use are emphasized. Global management conformed to CPGs by 56%. Conclusions: Important differences between adult and pediatric management were reported, without any impact on survival. A few patients can be included in clinical trials: Homogeneity in management could improve specific care for AYAs.

PURPOSE: Plasmablastic lymphoma (PBL) is a rare variant of diffuse large B cell lymphomas (DLBCL) clinically characterized by a poorer prognostic. Few clinical and imaging data are available and derived from pooled case reports and small series. The aim of the study was to evaluate the FDG avidity at baseline and the utility of 18-Fluorodeoxyglucose (FDG) positron-emission-tomography/computed-tomography (PET/CT) for staging and response assessment. METHODS: Patients with newly diagnosed PBL seen at Lymphoma Study Association centers during the period 2005-2015 were included if they underwent a PET/CT at staging and at the end of treatment (eotPET) and had received an anthracycline-based first line therapy. EotPET scans were analyzed using the 5-point-scale visual analysis in accordance with Lugano criteria. Patients were classified in complete metabolic response (CMR) or no-CMR including partial metabolic response (PMR), stable disease (SD) and progression disease (PD). EotPET results were assessed for the ability to predict event free survival (EFS) and overall survival (OS). RESULTS: Thirty-five PBL patients fulfilled the inclusion criteria. The median follow-up was 34 months (2.8-120 months). FDG avidity was found in all patients at diagnosis. Most patients (80%) achieved CMR, and 20% were no-CMR including 9% PMR, 6% SD, and 6% PD. A CMR after first line chemotherapy predicted higher EFS (p < 0.0001) and OS (p = 0.0006). CONCLUSIONS: This study confirmed the FDG avidity of PBL subtype and the usefulness of PET/CT scanning in restaging an aggressive lymphoma at the completion of chemotherapy. EotPET can predict outcomes following treatment in patients with PBL.

Primary CNS lymphoma (PCNSL) is chemosensitive to high-dose methotrexate-based chemotherapy. However, responses in the elderly are short-lasting and outcome is poor. Given that radiotherapy and intensive chemotherapy expose elderly to severe toxicities, alternative consolidation approaches need to be evaluated. In this multicenter study, we retrospectively analyzed consecutive patients with newly-diagnosed PCNSL, aged >60, treated with a (R)-MPV-AAA regimen. The regimen consisted of three 28-day cycles of methotrexate (3.5 g/m2 D1, D15), procarbazine, vincristine, followed by three 28-day cycles of cytarabine consolidation (3 g/m2 D1-2). Addition of rituximab (375 mg/m2 D1) was optional. The results were compared with the historical MPV-A regimen. Ninety patients received the (R)-MPV-AAA regimen with (n = 39) or without (n = 51) rituximab. Median age was 68 and median KPS 60. 55% of patients achieved a complete response, 8% a partial response and 37% progressed. The median PFS was 10 months, the median OS 28.1 months. Toxicity was mainly hematological, with 54 and 51% of grade III-IV neutropenia and thrombopenia. The response rate was higher in patients receiving rituximab (77 vs. 53%; p = 0.03), whereas no difference was observed in terms of PFS or OS. When comparing the results to the historical MPV-A, there was no difference in terms of response rate, PFS or OS, but a higher rate of hematotoxicity. This study suggests that extending cytarabine consolidation after methotrexate-based chemotherapy does not improve the MPV-A efficacy but increases toxicity in the elderly. The addition of rituximab may improve the response rate, but its impact on final outcome remains unclear.

Plasma-cell post-transplantation lymphoproliferative disorder (PC-PTLD) is a rare monomorphic PTLD entity divided into plasma cell myeloma (PCM) and plasmacytoma-like lesion (PLL) PTLD. To date, there are no exhaustive published cytogenetic data on PC-PTLD. We report array-based comparative genomic hybridization (aCGH) of 10 cases of PCM and PLL-PTLD. Patients had received kidney (n = 6), heart (n = 2), lung (n = 1) or bone marrow (n = 1) transplantation. There were six men and median age at time of PTLD was 56.5 years (3-74). We identified two different cytological features, plasmacytic and plasmablastic, among six PLL and three PCM PTLD. Eight cases were associated with EBV. First line treatment was heterogeneous: rituximab alone (n = 5), CHOP-like (n = 3) and multiple myeloma-like (n = 1). One patient died before any treatment. After a median follow-up of 19.5 months (0-150), five patients died (four from PTLD) and five were alive without evidence of disease. By aCGH, 5/10 demonstrated a complex profile. The most frequent abnormalities were +7q (5/10), +16q (5/10), +17q (5/10), +17p (4/10), +5q (4/10), t7 (4/10), t9 (3/10), del1p (3/10). No del17p13 (TP53) were observed. Del1p32.3 (CDKN2C) was observed in 2 cases. On univariate prognostic analysis, a complex aCGH was associated with a shorter OS. Thus, cytogenetic abnormalities seem to be closely related to those reported in multiple myeloma or diffuse large B cell lymphoma. Complex aCGH constitutes an unfavorable prognostic marker and aCGH should be integrated in the evaluation of patients with PLL/PCM-PTLD. © 2016 Wiley Periodicals, Inc.

BACKGROUND: The optimal follow-up strategy for primary central nervous system lymphoma (PCNSL) patients after first-line therapy is unclear. The goal of this study is to determine the utility of planned brain surveillance imaging in the detection of relapse in a retrospective cohort of PCNSL patients. METHODS: Patients were consecutive PCNSL cases treated in Leon Berard Cancer Centre, Lyon, France, from 1985 to 2011. Histology was diffuse large B-cell lymphoma in 94%. Patients were treated by methotrexate (92%) and cytarabine (63%) based-chemotherapy followed by radiotherapy for 108 patients (51%). Clinical records were reviewed for details at relapse and relationship to planned imaging. The imaging follow-up strategy was performed according to each treating physicians. RESULTS: Among 209 PCNSL patients, 127 complete response patients entered in post-treatment observation and 63 (50%) subsequently relapsed. Among the 125 evaluable patients, the majority of relapses (N = 49, 80%) was asymptomatic and identified before the planned brain imaging. Surveillance imaging detected relapses before symptoms in 12 patients who entered in post-therapy observation (10%). The median number of brain imaging during the follow-up was 7 (0-13). A total of 819 MRI/CT-scan were performed leading to the detection of 12 asymptomatic relapses. The one year OS rates were 41% and 58% for symptomatic and non-symptomatic relapses, respectively (P = 0.21). CONCLUSION: The majority of PCNSL relapses occurred outside planned follow-up with no difference in patient outcome between symptomatic and asymptomatic relapses. The role of brain imaging for the detection of relapses in the follow-up of PCNSL patients remains to be clarified.

Rituximab was approved in France in 2004, following randomized trials that demonstrated efficacy in newly diagnosed high tumour burden follicular lymphoma (FL). This retrospective study compared the management and outcome of FL in unselected patients treated in a single institution before and after rituximab approval. Two hundred and forty-seven adult patients were referred with first-line FL between 1996 and 2010 and are included in this study. The 103 pre-rituximab patients comprising cohort 1 were diagnosed between January 1996 and December 2003; cohort 2 includes the 144 patients diagnosed after the approval of rituximab between January 2004 and December 2010. Baseline clinical and biological data, type of therapy, treatment response, progression-free survival (PFS) and overall survival (OS) rates were compared. There were no statistically significant differences between the two cohorts with respect to baseline clinical and disease characteristics, including FL International Prognostic Index score. The major difference between the two cohorts is the use of rituximab in first line. Seventy-one per cent of patients in cohort 2 received rituximab (19% alone, 52% with chemotherapy) versus 10% in cohort 1 (2% alone, 8% with chemotherapy; p < 0.0001). The objective response rate (ORR) was significantly higher for cohort 2 (ORR 84% compared with 72% for cohort 1; p = 0.03). The PFS and OS rates were also significantly better: 3-year PFS 72% [95% confidence interval (CI) 64-80%] versus 55% (95% CI 45-64%), p = 0.0039 and 3-year OS 98% (95% CI 94-99%) versus 83% (95% CI 74-90%), p = 0.0007. Effect of period of study is significant when using multivariate analysis on PFS and OS and lactate dehydrogenase level (PFS and OS) and age (OS). These data from everyday practice confirm the benefit for patients with FL treated in the last decade through availability of rituximab in first line used alone or in association with various chemotherapy regimens.

UNLABELLED: BASIC: To describe the main characteristics and treatment of sarcoidosis in patients with chronic hepatitis C virus (HCV) infection. METHODS: Retrospective cohort study of patients with chronic HCV infection and sarcoidosis at our tertiary institution. RESULTS: Eleven cases (eight women, three men) fulfilled the criteria for sarcoidosis. Four cases belong to our population of 3194 (0.12%) HCV patients seen in our department between 2001 and 2008. In five cases, sarcoidosis was triggered by antiviral therapy (consisted of interferon-alpha monotherapy in one case and combined therapy with interferon-alpha and ribavirin in four cases) and developed from 23 to 82 months after completion of therapy in three cases. For these patients, pulmonary adenopathies were found in three patients while two presented cutaneous involvement, one had uveitis and one presented both arthritis and extrapulmonary lymphadenopathies. Two patients received systemic corticosteroids with a favourable outcome. Four treatment-naive patients developed sarcoidosis. Two had pulmonary disease, one had medullar involvement, one had superficial lymphadenopathy and one had arthralgia. Three patients received systemic corticosteroids with chronic outcome in all cases. One of the two patients with an earlier history of sarcoidosis experienced a benign relapse that resolved spontaneously. CONCLUSION: Clinical manifestations of sarcoidosis may occur in HCV patients, especially during or after treatment with immunotherapy. In our experience, sarcoidosis triggered by antiviral therapy was more frequent after completion of therapy, but concording with literature, presented a benign outcome. In sarcoidosis, seen in treatment-naive HCV patients, systemic corticosteroids had to be used more often and outcome was less favourable.
