(R)-CHOP-14 has substantially improved outcome in DLBCL, but may have increased morbidity and reduced quality of life (QoL). Our aim was to evaluate QoL during (R)-CHOP-14-based chemotherapy. Twenty-six patients participated (small single-center study). EORTC QLQ-C30 was completed pre-treatment, mid-treatment, 14 days post-treatment, and 3 months post-treatment. Scores were compared to a reference population, and analyzed separately. Pre-treatment, global health status ( p == 0.004), physical functioning ( p == 0.036), role functioning ( p == 0.017), and emotional functioning ( p == 0.040) were reduced, and fatigue ( p == 0.009) and appetite loss ( p == 0.007) increased compared to the reference population. During treatment, physical functioning and role functioning decreased significantly, whereas emotional functioning, fatigue, and diarrhea increased. Three months post-treatment, scores were generally equivalent to those of the reference population, and lower for nausea/vomiting ( p < 0.001) and constipation ( p < 0.001). Disease-related symptoms were frequent in high-risk DLBCL. Treatment-related symptoms were normalized 3 months post-treatment. In conclusion, QoL is only temporarily affected during (R)-CHOP-14-based chemotherapy, and the treatment regimen is therefore feasible. [ABSTRACT FROM AUTHOR]

The introduction of rituximab and generally improved health among elderly patients have increased the survival of patients with diffuse large B-cell lymphoma (DLBCL). The International Prognostic Index (IPI) from 1992 is based on pre-rituximab data from clinical trials including several lymphoma subtypes. We applied IPI factors to a population-based rituximab-treated cohort of 1990 patients diagnosed 2000–2010 and explored new factors and the optimal prognostic age cut-off for DLBCL. Multivariate-analyses (MVA) confirmed the prognostic value of all IPI factors except the presence of > 1 extranodal lesion. The optimal age cut-off was 70 years. In a MVA of albumin, lymphocyte count, sex, immunoglobulin G, bulky disease, hemoglobin and B-symptoms, only albumin was prognostic. We propose: (1) a modified DLBCL prognostic index (DLBCL-PI) including: age (70 years), performance status (PS), lactate dehydrogenase (LDH), stage and albumin level, and (2) a separate age-adjusted DLBCL-PI for patients ≤ 70 years including PS, LDH, albumin level and > 1 extranodal lesion, however excluding stage.

Addition of etoposide to the R-CHOP chemotherapy regimen with cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab (R-CHOEP) has resulted in improved survival in young patients with high-risk diffuse large B-cell lymphoma (DLBCL). It is not known whether biological factors can predict this effect. In this study, 245 patients representing all young patients with high-risk DLBCL treated with R-CHOP or R-CHOEP in 2004-2012 in Denmark were extracted from the Danish lymphoma database. Patients were stratified according to cell of origin (COO) into germinal-center B-cell-like (GCB) or non-GCB by Hans' algorithm. Only in patients with the GCB phenotype was treatment with R-CHOEP associated with improved progression-free survival (PFS) and overall survival (OS) compared with R-CHOP. Patients with GCB phenotype treated with R-CHOEP also had superior OS compared with patients with non-GCB phenotype treated with R-CHOEP. This was not seen in R-CHOP treated patients. This could suggest that R-CHOEP should be restricted to patients with GCB phenotype. [ABSTRACT FROM AUTHOR]

The aim of this study was to evaluate the prognostic value of clinician interpretation of positron emission tomography/computed tomography (PET/CT) reports at mid-therapy, interim PET (I-PET) and after the end of first-line therapy (E-PET) in patients with diffuse large B-cell lymphoma (DLBCL). Four hundred and thirty patients were enrolled in this study comprising a total of 617 PET reports. Each report was evaluated by three expert hematologists randomly selected from a panel of nine. Reports were labeled positive or negative if all three interpreters agreed. All others were considered indeterminate. Indeterminate reports accounted for 59% of I-PET and 49% of E-PET reports. Two-year overall survival (OS) for patients with a positive, indeterminate and negative I-PET was 58%, 87% and 89% ( p < 0.001), respectively. Two-year OS for patients with E-PET was 41%, 89% and 97% ( p < 0.001) for positive, indeterminate and negative interpretation of PET/CT reports. Progression-free survival and OS did not differ significantly in patients with a negative and an indeterminate I-PET report. The use of well-defined reporting criteria, e.g. the Deauville five-point scale, is likely to reduce the number of scans perceived as indeterminate. [ABSTRACT FROM AUTHOR]
