SummaryBackground Dose intensifi cation with a combination of cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) every 2 weeks improves outcomes in patients older than 60 years with diff use large B-cell lymphoma compared with CHOP every 3 weeks. We investigated whether this survival benefi t from dose intensifi cation persists in the presence of rituximab (R-CHOP) in all age groups.

Summary
Background
Mycosis fungoides (MF) and Sézary Syndrome (SS) are the most common cutaneous T‐cell lymphomas. MF/SS is accompanied by considerable morbidity from pain, itching and disfigurement.
Aim
To identify factors associated with poorer health‐related quality of life (HRQoL) in patients newly diagnosed with MF/SS.
Methods
Patients enrolled into Prospective Cutaneous Lymphoma International Prognostic Index (PROCLIPI; an international observational study in MF/SS) had their HRQoL assessed using the Skindex‐29 questionnaire. Skindex‐29 scores were analysed in relation to patient‐ and disease‐specific characteristics.
Results
The study population consisted of 237 patients [60·3% male; median age 60 years, (interquartile range 49–70)], of whom 179 had early MF and 58 had advanced MF/SS. In univariate analysis, HRQoL, as measured by Skindex‐29, was worse in women, SS, late‐stage MF, those with elevated lactate dehydrogenase, alopecia, high modified Severity Weighted Assessment Tool and confluent erythema. Linear regression models only identified female gender (β = 8·61; P = 0·003) and alopecia (β = 9·71, P = 0·02) as independent predictors of worse global HRQoL. Item‐level analysis showed that the severe impairment in symptoms [odds ratio (OR) 2·14, 95% confidence interval (CI) 1·19–3·89] and emotions (OR 1·88, 95% CI 1·09–3·27) subscale scores seen in women was caused by more burning/stinging, pruritus, irritation and greater feelings of depression, shame, embarrassment and annoyance with their diagnosis of MF/SS.
Conclusions
HRQoL is significantly more impaired in newly diagnosed women with MF/SS and in those with alopecia. As Skindex‐29 does not include existential questions on cancer, which may cause additional worry and distress, a comprehensive validated cutaneous T‐cell lymphoma‐specific questionnaire is urgently needed to more accurately assess disease‐specific HRQoL in these patients.
What's already known about this topic?
Cross‐sectional studies of mixed populations of known and newly diagnosed patients with mycosis fungoides (MF)/Sézary syndrome (SS) have shown significant impairment in health‐related quality of life (HRQoL).
Previous studies on assessing gender‐specific differences in HRQoL in MF/SS are conflicting.
More advanced‐stage disease and pruritus is associated with poorer HRQoL in patients with MF/SS.
What does this study add?
This is the first prospective study to investigate HRQoL in a homogenous group of newly diagnosed patients with MF/SS.
In patients newly diagnosed with MF/SS, HRQoL is worse in women and in those with alopecia and confluent erythema.
MF/SS diagnosis has a multidimensional impact on patient HRQoL, including a large burden of cutaneous symptoms, as well as a negative impact on emotional well‐being.
BackgroundCentral nervous system (CNS) relapse of diffuse large B-cell lymphoma (DLBCL) is associated with a dismal prognosis. Here, we report an analysis of CNS relapse for patients treated within the UK NCRI phase III R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone) 14 versus 21 randomised trial.Patients and methodsThe R-CHOP 14 versus 21 trial compared R-CHOP administered two- versus three weekly in previously untreated patients aged ≥18 years with bulky stage I–IV DLBCL (n = 1080). Details of CNS prophylaxis were retrospectively collected from participating sites. The incidence and risk factors for CNS relapse including application of the CNS-IPI were evaluated.Results177/984 patients (18.0%) received prophylaxis (intrathecal (IT) methotrexate (MTX) n = 163, intravenous (IV) MTX n = 2, prophylaxis type unknown n = 11 and IT MTX and cytarabine n = 1). At a median follow-up of 6.5 years, 21 cases of CNS relapse (isolated n = 11, with systemic relapse n = 10) were observed, with a cumulative incidence of 1.9%. For patients selected to receive prophylaxis, the incidence was 2.8%. Relapses predominantly involved the brain parenchyma (81.0%) and isolated leptomeningeal involvement was rare (14.3%). Univariable analysis demonstrated the following risk factors for CNS relapse: performance status 2, elevated lactate dehydrogenase, IPI, >1 extranodal site of disease and presence of a ‘high-risk’ extranodal site. Due to the low number of events no factor remained significant in multivariate analysis. Application of the CNS-IPI revealed a high-risk group (4-6 risk factors) with a 2- and 5-year incidence of CNS relapse of 5.2% and 6.8%, respectively.ConclusionDespite very limited use of IV MTX as prophylaxis, the incidence of CNS relapse following R-CHOP was very low (1.9%) confirming the reduced incidence in the rituximab era. The CNS-IPI identified patients at highest risk for CNS recurrence.ClinicalTrials.govISCRTN number 16017947 (R-CHOP14v21); EudraCT number 2004-002197-34.
