Abstract (Expand)

BACKGROUND: To improve outcome of elderly patients with diffuse large B-cell lymphoma, dose-dense rituximab was evaluated in the prospective DENSE-R-CHOP-14 trial. PATIENTS AND METHODS: Rituximab (375 … mg/m(2)) was given on days 0, 1, 4, 8, 15, 22, 29, 43, 57, 71, 85, and 99 together with six CHOP-14 cycles. Results were to be compared with patients who had received the same chemotherapy in combination with eight 2-week applications of rituximab in RICOVER-60. RESULTS: One hundred twenty-four patients are assessable. Dose-dense rituximab resulted in considerably higher serum levels during the first 50 days of treatment, but rituximab exposure time was not prolonged. Grade 3 and 4 infections were exceptionally high in the first 20 patients without anti-infective prophylaxis, but decreased after introduction of prophylaxis with aciclovir and cotrimoxazole in the remaining 104 patients (from 13% to 6% per cycle and from 35% to 18% per patient; P = 0.007 and P = 0.125, respectively). Patients with international prognostic index = 3-5 had higher complete response/complete response unconfirmed rates (82% versus 68%; P = 0.033) than in the respective RICOVER-60 population, but this did not translate into better long-term outcome, even though male hazard was decreased (event-free survival: from 1.5 to 1.1; progression-free survival: from 1.7 to 1.1; overall survival: from 1.4 to 1.0). CONCLUSIONS: Dose-dense rituximab achieved higher rituximab serum levels, but was not more effective than eight 2-week applications in the historical control population, even though minor improvements in poor-prognosis and male patients cannot be excluded. The increased, though manageable toxicity, precludes its use in routine practice. Our results strongly support anti-infective prophylaxis with aciclovir and cotrimoxazole for all patients receiving R-CHOP.

Prevalence of minor depression in elderly persons with and without mild cognitive impairment: a systematic review.
LIFE Adult

Abstract (Expand)

BACKGROUND: Minor depression (MinD) and mild cognitive impairment (MCI) are common disorders in late life that often coexist. The aim of the present review is to demonstrate prevalence rates of minor … depression in older patients with and without MCI. METHODS: Electronic database searches were performed through Medline, ISI Web of Knowledge, Psycinfo, and Cochrane library. Two independent reviewers extracted the original studies based on inclusion criteria: representative study population aged 55 and older, diagnostics of MinD according to DSM. Data on prevalence rates, risk factors, comorbidity and health care usage were analyzed. RESULTS: Point prevalence for MinD is higher in medical settings (median 14.4%) than in the community-based settings (median 10.4%) and primary care patients (median 7.7%). Although minor depression is rarely investigated in elderly persons with MCI, nearly 20% of patients with MCI seem to suffer from MinD. No data was found on the prevalence of MCI in patients with MinD. Risk factors associated with MinD include female gender, history of cerebrovascular diseases, generalized anxiety disorder, loneliness, and long-term institutional care. LIMITATIONS: Methodological differences of included studies resulted in a broad range of prevalence rates. No data is shown regarding the prevalence of MCI in MinD group due to insufficient evidence. CONCLUSIONS: Our review indicates that MinD is frequent in elderly population. MCI among those subjects has not been sufficiently investigated. Future studies based on clinical structured interviews should be performed in longitudinal design in order to differentiate late-life depression from progressive MCI or early manifestation of Alzheimer's disease.

Outcome of elderly patients with diffuse large B-cell lymphoma treated with R-CHOP: results from the UK NCRI R-CHOP14v21 trial with combined analysis of molecular characteristics with the DSHNHL RICOVER-60 trial.
GLA - German Lymphoma Alliance

Abstract (Expand)

Background: There is an on-going debate whether 2- or 3-weekly administration of R-CHOP is the preferred first-line treatment for elderly patients with diffuse large B-cell lymphoma (DLBCL). The UK … NCRI R-CHOP14v21 randomized phase 3 trial did not demonstrate a difference in outcomes between R-CHOP-14 and R-CHOP-21 in newly diagnosed DLBCL patients aged 19-88 years, but data on elderly patients have not been reported in detail so far. Here, we provide a subgroup analysis of patients >/=60 years treated on the R-CHOP14v21 trial with extended follow-up. Patients and methods: Six hundred and four R-CHOP14v21 patients >/=60 years were included in this subgroup analysis, with a median follow-up of 77.7 months. To assess the impact of MYC rearrangements (MYC-R) and double-hit-lymphoma (DHL) on outcome in elderly patients, we performed a joint analysis of cases with available molecular data from the R-CHOP14v21 (N = 217) and RICOVER-60 (N = 204) trials. Results: Elderly DLBCL patients received high dose intensities with median total doses of >/=98% for all agents. Toxicities were similar in both arms with the exception of more grade >/=3 neutropenia (P < 0.0001) and fewer grade >/=3 thrombocytopenia (P = 0.05) in R-CHOP-21 versus R-CHOP-14. The elderly patient population had a favorable 5-year overall survival (OS) of 69% (95% CI: 65-73). We did not identify any subgroup of patients that showed differential response to either regimen. In multivariable analysis including individual factors of the IPI, gender, bulk, B2M and albumin levels, only age and B2M were of independent prognostic significance for OS. Molecular analyses demonstrated a significant impact of MYC-R (HR = 1.96; 95% CI: 1.22-3.16; P = 0.01) and DHL (HR = 2.21; 95% CI: 1.18-4.11; P = 0.01) on OS in the combined trial cohorts, independent of other prognostic factors. Conclusions: Our data support equivalence of both R-CHOP application forms in elderly DLBCL patients. Elderly MYC-R and DHL patients have inferior prognosis and should be considered for alternative treatment approaches. Trial numbers: ISCRTN 16017947 (R-CHOP14v21); NCT00052936 (RICOVER-60).

Obesity negatively impacts outcome in elderly female patients with aggressive B-cell lymphomas treated with R-CHOP: results from prospective trials of the German high grade non-Hodgkin's lymphoma trial group.
GLA - German Lymphoma Alliance

Abstract (Expand)

To study if obesity is a risk factor in elderly patients (>60 years) with aggressive B-cell lymphoma, the outcomes of 576 elderly patients treated with rituximab in the RICOVER-60 trial were analysed … in a retrospective study with regard to body mass index (BMI) and gender. Of the 576 patients, 1% had low body weight (BMI < 18.5), 38% were normal weight (18.5 </= BMI < 25), 42% were overweight (25 </= BMI < 30) and 19% were obese (BMI >/= 30). Event-free (EFS), progression-free (PFS) and overall survival (OS) according to BMI showed no significant differences for all and for male patients. EFS (P = 0.041), PFS (P = 0.038) and OS (P = 0.031) were significantly better for female non-obese patients. A multivariate analysis adjusted for International Prognostic Index risk factors confirmed these results, with the following hazard ratios (HR) for obesity (BMI >/= 30) for EFS/PFS/OS: all patients - 1.4/1.4/1.4 (not significant); male patients - 1.2/1.2/1.0 (not significant) and female patients - 1.7 (P = 0.032)/1.9 (P = 0.022)/2.0 (P = 0.017). In conclusion, obesity is a risk factor that influences treatment outcome in elderly female patients with aggressive B-cell lymphoma treated with R-CHOP (rituximab + cyclophosphamide, doxorubicin, vincristine, prednisolone). The inferior outcomes in obese female patients may be due to faster rituximab clearance in obese females.
