Both day 15 and day 28 status was classified as good ( smaller than = 20% leukemic blasts) in 77% of patients. The correlation between day 15 and 28 blast percentages was significant, Momelotinib but not strong (Spearman correlation coefficient = 0.49, P smaller than 0.001). Survival probability decreased in a stepwise fashion along with rising blast counts at day 28. Patients with bone marrow blast counts at this time-point of smaller than = 5%, 6-10%, 11-20% and bigger than 20% had 4-year probabilities of survival of 52%+/- 3% versus 36%+/- 10% versus 21%+/- 9% versus 14%+/- 4%, respectively, P smaller than 0.0001; this trend was not seen for day 15 results. Multivariate analysis showed
that early treatment response at day 28 had the strongest prognostic significance, superseding even time to relapse (
smaller than or bigger than = 12 selleck months). In conclusion, an early response to treatment, measured on day 28, is a strong and independent prognostic factor potentially useful for treatment stratification in pediatric relapsed acute myeloid leukemia. This study was registered with ISRCTN code: 94206677.”
“Gene expression profiling and immunohistochemical studies have demonstrated that nonmalignant tumor infiltrating inflammatory cells contribute to clinical outcome in patients with follicular lymphoma (FL). Particularly, tumor-associated macrophage (TAM) content correlates with longer survival rates check details after immunochemotherapy. Here we investigated the prognostic importance of tumor-associated mast cells (MCs) and their relation to TAMs in patients with FL treated with a combination of rituximab (R) and cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy. Of the 98 patients, 70 received R-CHOP at diagnosis and 28 at relapse. According to Kaplan-Meier estimates, the patients with high MC content had
a worse 4-year progression-free survival (PIFS) than the ones with low MC content after R-CHOP therapy (34% vs 74%, P = .002). The adverse prognostic value of MCs was seen both for the patients treated at diagnosis and at relapse, whereas no such impact on PFS was observed for the control patients treated with chemotherapy only (P = .4). When the TAM-related PIFS was analyzed separately in patients with high and low MC contents, the positive prognostic effect of TAM was seen only in patients with few MCs. Taken together, the data demonstrate that a high MC score is associated with unfavorable prognosis and it eliminates the positive prognostic value of TAMs in patients with FL treated with immunochemotherapy.”
