RESUMEN

We evaluated the safety and efficacy of standard-dose yttrium-90 (Y(90)) ibritumomab tiuxetan combined with high-dose BEAM (carmustine, etoposide, cytarabine, and melphalan) after first-line induction treatment in young patients with poor prognoses diffuse large B cell lymphoma (DLBCL) (clinicaltrials.gov: NCT00689169). Seventy-five high-risk (≥2 International Prognostic Index [IPI] factors) consecutive DLBCL patients (≤65 years old) in complete remission (CR) or partial remission (PR) after rituximab chemotherapy were treated with Y(90) ibritumomab tiuxetan and BEAM regimen followed by autologous stem cell transplantation (ASCT). The median follow-up was 34 months. Of the 75 patients, 71 underwent ASCT and were eligible for analysis. Median time to reach a neutrophil count of >500/µL and platelet count of >20,000/µL was 11 days. Mucositis ≥3 (51%) occurred in most patients. Other adverse events were similar to those seen with BEAM alone. The overall response rate was 86%; 59 patients (83%) achieved a CR or unconfirmed CR. The 2-year event-free survival (EFS), overall survival (OS), and disease-free survival were 79%, 83%, and 91%, respectively. Disease status (CR/PR) and positron emission tomography (PET) findings before transplantation did not predict treatment failure. The IPI (2 versus >2) and maximum tumor diameter of ≥10 cm at diagnosis appeared to be prognosis factors for OS but not for EFS. Adding Y(90) ibritumomab tiuxetan to BEAM is safe and does not increase transplantation-related toxicity. First-line consolidation with Y(90) ibritumomab tiuxetan and high-dose chemotherapy induced high rates of EFS and OS in poor-prognosis patients with DLBCL, regardless of PET status after induction treatment and warrants a randomized study.

RESUMEN

PURPOSE: Whether neutropenia has an impact on the mortality of critically ill cancer patients remains controversial, yet it is widely used as an admission criterion and prognostic factor. METHODS: Systematic review and meta-analysis. Studies on adult cancer patients and intensive care units were searched on PubMed and Cochrane databases (2005-2015). Summary estimates of mortality risk differences were calculated using the random-effects model. RESULTS: Among the 1,528 citations identified, 38 studies reporting on 6,054 patients (2,097 neutropenic patients) were included. Median mortality across the studies was 54% [45-64], with unadjusted mortality in neutropenic and non-neutropenic critically ill patients of 60% [53-74] and 47% [41-68], respectively. Overall, neutropenia was associated with a 10% increased mortality risk (6%-14%; I² = 50%). The admission period was not associated with how neutropenia affected mortality. Mortality significantly dropped throughout the study decade [-11% (-13.5 to -8.4)]. This mortality drop was observed in non-neutropenic patients [-12.1% (-15.2 to -9.0)] but not in neutropenic patients [-3.8% (-8.1 to +5.6)].Sensitivity analyses disclosed no differences in underlying malignancy, mechanical ventilation use, or Granulocyte-colony stimulating factor use. Seven studies allowed the adjustment of severity results (1,350 patients). Although pooled risk difference estimates were similar to non-adjusted results, there was no significant impact of neutropenia on mortality (risk difference of mortality, 9%; 95% CI, -15 to +33). CONCLUSION: Although the unadjusted mortality of neutropenic patients was 11% higher, this effect disappeared when adjusted for severity. Therefore, when cancer patients become critically ill, neutropenia cannot be considered as a decision-making criterion.

RESUMEN

BACKGROUND: Extranodal nasal-type NK/T-cell lymphoma is a rare and severe disease. Considering the rarity of this lymphoma in Europe, we conducted a multicentric retrospective study on nasal-type NK/T cell lymphoma to determine the optimal induction strategy and identify prognostic factors. METHODS: Thirty-six adult patients with nasal-type NK/T-cell lymphoma were recruited and assessed. In total, 80 % of patients were classified as having upper aerodigestive tract NK/T-cell lymphoma (UNKTL) and 20 % extra-upper aerodigestive tract NK/T-cell lymphoma (EUNKTL). RESULTS: For advanced-stage disease, chemotherapy alone (CT) was the primary treatment (84 % vs. 10 % for combined CT + radiation therapy (RT), respectively), while for early-stage disease, 50 % of patients received the combination of CT + RT and 50 % CT alone. Five-year overall survival (OS) and progression-free survival (PFS) rates were 39 % and 33 %. Complete remission (CR) rates were significantly higher when using CT + RT (90 %) versus CT alone (33 %) (p < 0.0001). For early-stage disease, CR rates were 37 % for CT alone versus 100 % for CT + RT. Quality of response was significantly associated with survival, with 5-year OS being 80 % for CR patients versus 0 % for progressive disease patients (p < 0.01). CONCLUSION: Early RT concomitantly or sequentially with CT led to improved patient outcomes, with quality of initial response being the most important prognosticator for 5-year OS.

RESUMEN

PURPOSE: In this large cohort of Hodgkin's lymphoma survivors with long follow-up, we estimated the impact of treatment regimens on premature ovarian failure (POF) occurrence and motherhood, including safety of nonalkylating chemotherapy and dose-response relationships for alkylating chemotherapy and age at treatment. PATIENTS AND METHODS: The Life Situation Questionnaire was sent to 1,700 women treated in European Organisation for Research and Treatment of Cancer and Groupe d'Étude des Lymphomes de l'Adulte trials between 1964 and 2004. Women treated between ages 15 and 40 years and currently not using hormonal contraceptives (n = 460) were selected to assess occurrence of POF. Cumulative POF risk was estimated using the life-table method. Predictive factors were assessed by Cox regression analysis. RESULTS: Median follow-up was 16 years (range, 5 to 45 years). Cumulative risk of POF after alkylating chemotherapy was 60% (95% CI, 41% to 79%) and only 3% (95% CI, 1% to 7%) after nonalkylating chemotherapy (doxorubicin, bleomycin, vinblastine, and dacarbazine; epirubicin, bleomycin, vinblastine, and prednisone). Dose relationship between alkylating chemotherapy and POF occurrence was linear. POF risk increased by 23% per year of age at treatment. In women treated without alkylating chemotherapy at age younger than 32 years and age 32 years or older, cumulative POF risks were 3% (95% CI, 1% to 16%) and 9% (95% CI, 4% to 18%), respectively. If menstruation returned after treatment, cumulative POF risk was independent of age at treatment. Among women who ultimately developed POF, 22% had one or more children after treatment, compared with 41% of women without POF. CONCLUSION: Nonalkylating chemotherapy carries little to no excess risk of POF. Dose-response relationships for alkylating chemotherapy and age at treatment are both linear. Timely family planning is important for women at risk of POF.
