: eBEACOPP is the most effective chemotherapy regimen for younger patients with early unfavorable (EU) and advanced-stage (AS) Hodgkin lymphoma (HL), albeit with significant toxicities. The ...14-day/cycle prednisone course contributes to side effects, including osteoarticular events like avascular bone necrosis (AVN). Our center has been using eBEACOPP since 2009 for AS and 2014 for EU patients. In 2016, we reduced prednisone treatment to 7-10 days to lessen AVN risk. We analyzed the effects of this approach.
: We retrospectively collected data on patients who received at least two cycles of eBEACOPP for first-line HL treatment.
: A total of 162 patients (33 EU, 129 AS) were included. Their median age was 31 (range 19-59 years), and 88 were males. A total of 94 patients received full corticosteroid courses, and 68 received reduced corticosteroid courses. The overall response rate (ORR) was 98%. Different corticosteroid dosings had no significant effect on ORR, febrile neutropenia episodes, or hospital admissions. After a median follow-up (mFU) of 58 months, the 5yPFS for the entire cohort was 98% vs. 95% for the standard course vs. the short corticosteroids course, respectively (
= 0.37), while the 5yOS was 98% vs. 99% for the standard course vs. short corticosteroids course, respectively (
= 0.87). In AS patients intended to be treated with six eBEACOPP cycles, 5yPFS and 5yOS were 100% vs. 97% and 100% vs. 99% for standard vs. short corticosteroid courses, respectively (
= 0.56 and
= 0.17). In EU patients, 5yPFS was 97% (standard) vs. 95% (short) (
= 0.98) and 5yOS 100% vs. 93.3% (
= 0.87). Osteoarticular events were numerically lower in patients receiving the shorter prednisone course, both in the whole cohort and in the subgroup of patients treated with six cycles of eBEACOPP, but this difference failed to reach statistical significance.
: eBEACOPP provides excellent and durable first-line disease control. Shortening the corticosteroid course does not compromise efficacy, potentially reducing toxicity. However, longer follow-ups and larger studies are needed for confirmation.
Glioblastoma multiforme (GBM) is the most common and most aggressive malignant primary brain tumor in humans. Clinically useful molecular markers that help predict response to therapy and prognosis ...are still rare. The research was conducted in 55 patients with GBM, 26 (47.3%) women and 29 (52.7%) men, mean age 62.58 years. On immunohistochemical analysis, primary antibody to CD44 (dilution 1:50) and primary antibody to endoglin (CD105) (dilution 1:250) were used to evaluate neovascularization. Statistical analysis showed negative correlation between CD44 and survival (p=0.023) (higher expression of CD44 was correlated with shorter survival), but there was no correlation between neovascularization determined by CD105 in GBM and patient survival. Thus, significant individual predictors of longer survival were lower expression of CD44 (p=0.004), higher Karnofsky score (p=0.045), and female gender (p=0.017). The results obtained suggested the possible role of CD44 in the progression and tumor neovascularization of GBM.

Statisticka analiza je pokazala negativnu korelaciju izmedu CD44 i prezivljenja (p=0,023) (veca ekspresija CD44 je korelirala s kracim prezivljenjem), ali nije bilo korelacije izmedu neovaskularizacije (odredene putem CD105) kod GBM i prezivljenja ovih bolesnika. Tako su znacajni pojedinacni prediktori duzeg prezivljenja bili niza ekspresija CD44 (p=0,004), veci Karnofskyjev zbir (p=0,045) i zenski spol (p=0,017).
