Management of children and adults with all stages of nodular lymphocyte predominant Hodgkin lymphoma - All StAGEs: A consensus-based position paper from the Hodgkin lymphoma subgroup of the UK National Cancer Research Institute.

A consensus statement for the management for patients of all ages with all stages of nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) - All StAGEs - is proposed by representatives of the UK National Cancer Research Institute (NCRI) Hodgkin lymphoma study group and the Children's Cancer & Leukaemia Group. Based on current practices and published evidence, a consensus has been reached regarding diagnosis, staging and risk-ik7 stratified management which includes active surveillance, low- and standard-dose immunochemotherapy and radiotherapy.

4 Gy versus 24 Gy radiotherapy for follicular and marginal zone lymphoma (FoRT): long-term follow-up of a multicentre, randomised, phase 3, non-inferiority trial.

BACKGROUND: The optimal radiotherapy dose for indolent non-Hodgkin lymphoma is uncertain. We aimed to compare 24 Gy in 12 fractions (representing the standard of care) with 4 Gy in two fractions (low-dose radiation). METHODS: FoRT (Follicular Radiotherapy Trial) is a randomised, multicentre, phase 3, non-inferiority trial at 43 study centres in the UK. We enrolled patients (aged >18 years) with indolent non-Hodgkin lymphoma who had histological confirmation of follicular lymphoma or marginal zone lymphoma requiring radical or palliative radiotherapy. No limit on performance status was stipulated, and previous chemotherapy or radiotherapy to another site was permitted. Radiotherapy target sites were randomly allocated (1:1) either 24 Gy in 12 fractions or 4 Gy in two fractions using minimisation and stratified by histology, treatment intent, and study centre. Randomisation was centralised through the Cancer Research UK and University College London Cancer Trials Centre. Patients, treating clinicians, and investigators were not masked to random assignments. The primary endpoint was time to local progression in the irradiated volume based on clinical and radiological evaluation and analysed on an intention-to-treat basis. The non-inferiority threshold aimed to exclude the chance that 4 Gy was more than 10% inferior to 24 Gy in terms of local control at 2 years (HR 1·37). Safety (in terms of adverse events) was analysed in patients who received any radiotherapy and who returned an adverse event form. FoRT is registered with ClinicalTrials.gov, NCT00310167, and the ISRCTN Registry, ISRCTN65687530, and this report represents the long-term follow-up. FINDINGS: Between April 7, 2006, and June 8, 2011, 614 target sites in 548 patients were randomly assigned either 24 Gy in 12 fractions (n=299) or 4 Gy in two fractions (n=315). At a median follow-up of 73·8 months (IQR 61·9-88·0), 117 local progression events were recorded, 27 in the 24 Gy group and 90 in the 4 Gy group. The 2-year local progression-free rate was 94·1% (95% CI 90·6-96·4) after 24 Gy and 79·8% (74·8-83·9) after 4 Gy; corresponding rates at 5 years were 89·9% (85·5-93·1) after 24 Gy and 70·4% (64·7-75·4) after 4 Gy (hazard ratio 3·46, 95% CI 2·25-5·33; p<0·0001). The difference at 2 years remains outside the non-inferiority margin of 10% at -13·0% (95% CI -21·7 to -6·9). The most common events at week 12 were alopecia (19 [7%] of 287 sites with 24 Gy vs six [2%] of 301 sites with 4 Gy), dry mouth (11 [4%] vs five [2%]), fatigue (seven [2%] vs five [2%]), mucositis (seven [2%] vs three [1%]), and pain (seven [2%] vs two [1%]). No treatment-related deaths were reported. INTERPRETATION: Our findings at 5 years show that the optimal radiotherapy dose for indolent lymphoma is 24 Gy in 12 fractions when durable local control is the aim of treatment.

Pediatric classical Hodgkin lymphoma.

Over the past century, classical Hodgkin lymphoma (HL) has been transformed from a uniformly fatal disease to one of the most curable cancers. Given the high cure rate, a major focus of classical HL management is reducing the use of radiation therapy (RT) and chemotherapy agents such as procarbazine and doxorubicin to minimize long-term toxicities. In both North America and Europe, an important philosophy in the management of classical HL is to guide the intensity of treatment according to the risk category of the disease. The main factors used for risk classification are tumor stage, bulk of disease, and the presence of B symptoms. Response to chemotherapy is an important factor guiding the utilization of RT in ongoing Children's Oncology Group (COG) and European Network Pediatric Hodgkin Lymphoma (EuroNet-PHL) trials. Both trial groups have transitioned to reduced RT volumes that target the highest risk sites using highly conformal techniques, along with standard or intensified chemotherapy regimens to improve outcomes in higher risk patients. However, given the potential acute toxicities of intensified chemotherapy, immunoregulatory drugs are being investigated in upcoming trials. The purpose of this review is to summarize current approaches to treating pediatric classical HL according to the COG and EuroNet-PHL.

Association of early disease progression and very poor survival in the GALLIUM study in follicular lymphoma: benefit of obinutuzumab in reducing the rate of early progression.

We evaluated early disease progression and its impact on overall survival (OS) in previously untreated follicular lymphoma patients in GALLIUM (clinicaltrials.gov identifier: 01332968), and investigated the effect on early disease progression of the two randomization arms: obinutuzumab-based versus rituximab-based immunochemotherapy. Cause-specific Cox regression was used to estimate the effect of treatment on the risk of disease progression or death due to disease progression within 24 months of randomization and to analyze OS in patients with or without disease progression after 24 months. Mortality in both groups was analyzed 6, 12, and 18 months post randomization (median follow up, 41 months). Fewer early disease progression events occurred in obinutuzumab (57 out of 601) versus rituximab (98 out of 601) immunochemotherapy patients, with an average risk reduction of 46.0% (95%CI: 25.0-61.1%; cumulative incidence rate 10.1% vs 17.4%). At a median post-progression follow up of 22.6 months, risk of mortality increased markedly following a progression event [HR of time-varying progression status, 25.5 (95%CI: 16.2-40.3)]. Mortality risk was higher the earlier patients progressed within the first 24 months. Age-adjusted HR for OS after 24 months in surviving patients with disease progression versus those without was 12.2 (95%CI: 5.6-26.5). Post-progression survival was similar by treatment arm. In conclusion, obinutuzumab plus chemotherapy was associated with a marked reduction in the rate of early disease progression events relative to rituximab plus chemotherapy. Early disease progression in patients with follicular lymphoma was associated with poor prognosis, with mortality risk higher after earlier progression. Survival post progression did not seem to be influenced by treatment arm.

Cardiac dysfunction in cancer survivors unmasked during exercise.

BACKGROUND: The cardiac dysfunction associated with anthracycline-based chemotherapy cancer treatment can exist subclinically for decades before overt presentation. Stress echocardiography, the measurement of left ventricular (LV) deformation and arterial haemodynamic evaluation, has separately been used to identify subclinical cardiovascular (CV) dysfunction in several patient groups including those with hypertension and diabetes. The purpose of the present cross-sectional study was to determine whether the combination of these techniques could be used to improve the characterisation of subclinical CV dysfunction in long-term cancer survivors previously treated with anthracyclines. MATERIALS AND METHODS: Thirteen long-term cancer survivors (36 ± 10 years) with prior anthracycline exposure (11 ± 8 years posttreatment) and 13 age-matched controls were recruited. Left ventricular structure, function and deformation were assessed using echocardiography. Augmentation index was used to quantify arterial haemodynamic load and was measured using applanation tonometry. Measurements were taken at rest and during two stages of low-intensity incremental cycling. RESULTS: At rest, both groups had comparable global LV systolic, diastolic and arterial function (all P > 0·05); however, longitudinal deformation was significantly lower in cancer survivors (-18 ± 2 vs. -20 ± 2, P < 0·05). During exercise, this difference between groups persisted and further differences were uncovered with significantly lower apical circumferential deformation in the cancer survivors (-24 ± 5 vs. -29 ± 5, -29 ± 5 vs. 35 ± 8 for first and second stage of exercise respectively, both P < 0·05). CONCLUSION: In contrast to resting echocardiography, the measurement of LV deformation at rest and during exercise provides a more comprehensive characterisation of subclinical LV dysfunction. Larger studies are required to determine the clinical relevance of these preliminary findings.

Short duration immunochemotherapy followed by radioimmunotherapy consolidation is effective and well tolerated in relapsed follicular lymphoma: 5-year results from a UK National Cancer Research Institute Lymphoma Group study.

UNLABELLED: We report a phase II study to evaluate the efficacy and toxicity of abbreviated immunochemotherapy followed by (90) Y Ibritumomab tiuxetan ((90) Y-IT) in patients with recurrent follicular lymphoma. Of the 52 patients enrolled, 50 were treated with three cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisolone) or R-CVP (rituximab, cyclophosphamide, vincristine, prednisolone), followed by (90) Y-IT regimen (15 MBq/kg, maximum 1200 MBq) preceded by two infusions of 250 mg/m(2) rituximab. The overall response rate was 98% with complete response (CR) 30% and partial response (PR) 68%. 18 patients with a PR following chemotherapy improved to a CR following (90) Y-IT: a conversion rate of 40%. Seven patients with PR following (90) Y-IT subsequently improved to a CR 12-18 months later, leading to an overall CR rate of 44%. With a median follow-up of 5 years, median progression-free survival was 23·1 months and overall survival was 77·5% at 5 years. High trough serum rituximab levels (median 112 µg/ml; range 52-241) were attained after four doses of rituximab, prior to (90) Y-IT; this was not found to influence response rates. The treatment was well tolerated with few (13·5%) grade 3 or 4 infective episodes and manageable haematological toxicity. Abbreviated immunochemotherapy followed by (90) Y-IT is an effective and well-tolerated treatment in recurrent follicular lymphoma patients previously exposed to rituximab. TRIAL REGISTRATION: clinicaltrials.gov identifier: NCT00637832.

The role of alisertib in treatment of peripheral T-cell lymphomas.

Peripheral T-cell lymphomas are aggressive lymphomas with poor outcomes for which novel treatments are urgently needed. Alisertib (MLN8237) is a second-generation oral Aurora A kinase inhibitor. Treatment with alisertib results in an accumulation of cells with abnormal mitotic spindles, leading to decreased proliferation and apoptosis in a range of human tumor cell lines. Alisertib has shown single-agent antitumor activity in animal xenograft models and promising antitumor activity alone or in combination with other agents in patients with solid and hematologic cancers, and T-cell lymphomas in particular. It is currently being tested in randomized controlled Phase III trials in relapsed/refractory peripheral T-cell lymphoma.

4 Gy versus 24 Gy radiotherapy for patients with indolent lymphoma (FORT): a randomised phase 3 non-inferiority trial.

BACKGROUND: Follicular lymphoma has been shown to be highly radiosensitive with responses to doses as low as 4 Gy in two fractions. This trial was designed to explore the dose response for follicular lymphoma comparing 4 Gy in two fractions with 24 Gy in 12 fractions METHODS: FORT is a prospective randomised, unblinded, phase 3 non-inferiority study comparing radiotherapy given as 4 Gy in two fractions with a standard dose of 24 Gy in 12 fractions. Entry criteria included all patients aged over 18 years, having local radiotherapy for radical or palliative local control, with follicular lymphoma or marginal zone lymphoma, who had received no previous treatment for at least 1 month before. The primary outcome was time to local progression analysed on an intention-to-treat basis. Randomisation was centralised through the Cancer Research UK and University College London Cancer Trials Centre. Radiotherapy target sites were randomised (1:1) with minimisation stratified by histology (follicular lymphoma vs marginal zone lymphoma), treatment intent (palliative or curative) and centre. This trial is registered with ClinicalTrials.gov number, NCT00310167. FINDINGS: 299 sites were randomly assigned to 24 Gy and 315 sites to 4 Gy between April 7, 2006, and June 8, 2011, at 43 centres in the UK. After a median follow-up of 26 months (range 0·39-75·4), 91 local progressions had been recorded (21 in the 24 Gy group and 70 in the 4 Gy group). Time to local progression with 4 Gy was not non-inferior to 24 Gy (hazard ratio 3·42, 95% CI 2·09-5·55, p<0·0001). Eight (3%) of 282 patients in the 24 Gy group and four (1%) of 300 in the 4 Gy group had acute grade 3-4 toxic effects. Four (1%) patients in the 24 Gy group and four (1%) patients in the 4 Gy group had late toxic effects. Mucositis was the most common event in the 24 Gy group (two patients with acute mucositis and two with late mucositis; all grade 3) and was not reported in the 4 Gy group. The most common acute effect was pain at the site of irradiation (two patients in the 4 Gy group, one patient in the 24 Gy group; all grade 3), and the most common late effect was fatigue (two patients in the 4 Gy group, one patient in the 24 Gy group; all grade 3). INTERPRETATION: 24 Gy in 12 fractions is the more effective radiation schedule for indolent lymphoma and should be regarded as the standard of care. However, 4 Gy remains a useful alternative for palliative treatment. FUNDING: Cancer Research UK.

Ofatumumab monotherapy in rituximab-refractory follicular lymphoma: results from a multicenter study.

New treatments are required for rituximab-refractory follicular lymphoma (FL). In the present study, patients with rituximab-refractory FL received 8 weekly infusions of ofatumumab (CD20 mAb; dose 1, 300 mg and doses 2-8, 500 or 1000 mg; N = 116). The median age of these patients was 61 years, 47% had high-risk Follicular Lymphoma International Prognostic Index scores, 65% were chemotherapy-refractory, and the median number of prior therapies was 4. The overall response rate was 13% and 10% for the 500-mg and 1000-mg arms, respectively. Among 27 patients refractory to rituximab monotherapy, the overall response rate was 22%. The median progression-free survival was 5.8 months. Forty-six percent of patients demonstrated tumor reduction 3 months after therapy initiation, and the median progression-free survival for these patients was 9.1 months. The most common adverse events included infections, rash, urticaria, fatigue, and pruritus. Three patients experienced grade 3 infusion-related reactions, none of which were considered serious events. Grade 3-4 neutropenia, leukopenia, anemia, and thrombocytopenia occurred in a subset of patients. Ofatumumab was well tolerated and modestly active in this heavily pretreated, rituximab-refractory population and is therefore now being studied in less refractory FL and in combination with other agents in various B-cell neoplasms. The present study was registered at www.clinicaltrials.gov as NCT00394836.

A multicentre, phase II trial of ofatumumab monotherapy in relapsed/progressive diffuse large B-cell lymphoma.

This international, multicentre phase II study was conducted to assess ofatumumab, a human anti-CD20 monoclonal antibody, in patients with relapsed/progressive diffuse large B-cell lymphoma (DLBCL) who were ineligible for autologous stem cell transplantation (TI) or who had relapse/progression after transplantation (PT). Eighty-one patients received ofatumumab 300 mg intravenously (IV) on Day 1, followed by seven weekly IV infusions of 1000 mg. Patients in the TI and PT groups had received a median of 3 (range, 1-7) and 5 (range, 2-7) prior therapies, respectively. One-third of patients did not respond to the last prior therapy, and 53% had failed two or more rituximab-containing therapies. Overall response rate was 13% for the TI group (seven partial responses) and 8% for the PT group (two complete responses). Median progression-free survival was 2·6 months, and median duration of response was 9·5 months. The most common Grade 3-4 adverse events were neutropenia (11%), leucopenia (6%), lymphopenia (6%) and thrombocytopenia (6%). Sixteen deaths have been reported, with disease progression as the most common cause of death. In conclusion, ofatumumab monotherapy was well tolerated and provided clinical benefit to some DLBCL patients in this study.

Prognostic significance of hypoxia inducible factor-1α and vascular endothelial growth factor expression in patients with diffuse large B-cell lymphoma treated with rituximab.

We evaluated hypoxia inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) expression and their prognostic significance in diffuse large B-cell lymphoma (DLBCL). Expression of HIF-1α and VEGF was studied in 78 patients and results correlated with clinicopathological and prognostic data. HIF-1α and VEGF were expressed in 67% and 84% of patients, respectively, and a significant correlation was demonstrated between them (p < 0.001). Outcome was analyzed according to treatment. HIF-1α positive patients given rituximab demonstrated improved outcome, with 5-year overall survival of 72% for those receiving rituximab versus 65% for those not receiving rituximab, and 5-year progression-free survival (PFS) 76% versus 57%. No correlation was demonstrated between HIF-1α and other prognostic biomarkers including BCL6, CD10 and MUM-1. We demonstrated significantly improved PFS (p = 0.003) in patients receiving rituximab and showing BCL6 overexpression. The results confirm the significant association between HIF-1α and VEGF expression and suggest that HIF-1α expression is a favorable prognostic factor in patients with DLBCL treated with rituximab.

Correlates of fertility issues in an internet survey of cancer survivors.

PURPOSE: The objectives of this study were (1) to determine what young cancer survivors know about the effect of their cancer on fertility, how fertility difficulties affected their lives and whether they would opt for fertility preservation (FP) and (2) to assess the sources of information and the helpfulness of them. METHODS: Women of at least 18 years with cancer affecting reproductive function were recruited from eight cancer websites for this online survey. The Cancer and Fertility Survey (CFS) contained items from validated inventories and items to assess fertility issues in cancer patients. Quantitative analyses (t-tests, chi(2), analysis of variance) and thematic analysis of free text data were performed. RESULTS: Of the 80 participating women, 68.1% rated the risk of infertility as high. The mean number of professionals consulted was 3.56 (SD = 2.7), but 20% of women had not discussed fertility with any professional. The weighted mean helpfulness index was the highest for spouses and oncologists. Strength of positive attitudes towards FP was significantly greater than that of negative attitudes. CONCLUSION: The need to discuss fertility is high among women searching for information on cancer websites. Options to preserve fertility were positively viewed but the actual use may be limited by concerns about safety.

Five years' experience treating locally advanced cervical cancer with concurrent chemoradiotherapy and high-dose-rate brachytherapy: results from a single institution.

PURPOSE: To assess the clinical outcomes after concurrent cisplatin chemotherapy and radiotherapy (RT) followed by high-dose-rate brachytherapy for locally advanced carcinoma of the cervix and perform a multivariate analysis of the prognostic factors. METHODS AND MATERIALS: The outcomes were analyzed for all women treated between 1999 and 2004 with concurrent cisplatin chemotherapy and RT followed by high-dose-rate brachytherapy. Kaplan-Meier analysis was used for overall survival (OS), local control (LC), and distant control (DC). The Cox proportional hazards model was used to perform multivariate analysis of the prognostic variables. RESULTS: The standard regimen comprised whole pelvic external RT 45 Gy in 25 fractions with concurrent weekly cisplatin 40 mg/m(2), followed by four high-dose-rate brachytherapy insertions of 6 Gy. Patients with radiologically enlarged para-aortic lymph nodes underwent extended-field RT. Of 92 patients, the OS rate was 72% at 2 years and 55% at 5 years. The LC rate was 76% at 2 years and 67% at 5 years. The DC rate was 68% at 2 years and 48% at 5 years. The most important prognostic factor for OS, LC, and DC was the pretreatment hemoglobin. For OS, the tumor size and the presence of enlarged lymph nodes were also important. For LC, the number of brachytherapy insertions was important; and for DC, the number of chemotherapy treatments was important. Of the patients, 4% experienced late Grade 3 or 4 toxicity. CONCLUSION: The results of our study have shown that the regimen is effective, with acceptable long-term side effects. In this cohort, the most important prognostic factor was the pretreatment hemoglobin level, a disease-related factor. However, more effective systemic treatments are needed.
