PRO/CON Chul Soo Ha, MD If systemic treatment is effective enough to reliably control not only microscopic but also bulky disease, there will be little role for radiotherapy. And if systemic treatment cannot even reliably control microscopic disease, let alone macroscopic disease, there will be little role for radiotherapy, either.
PRO/CON Soham Puvvada, MD, Thomas Miller, MD DLBCL of any stage remains a systemic disease with early hematogenous spread. Thus, arguments advocating the role of IFRT do not truly address disease biology, and all future efforts to cure patients will require improved systemic therapy.
RESEARCH REPORT Michael Kaufman A dose-adjusted regimen of etoposide, doxorubicin, and cyclophosphamide with vincristine, prednisone, and rituximab (DA-EPOCH-R) obviated the need for radiotherapy in patients with primary mediastinal B-cell lymphoma in a single-group, phase II, prospective study.
RESEARCH REPORT Anna Azvolinsky Researchers have identified a novel monoclonal antibody directly targeted against a receptor found in abundance on chronic lymphocytic leukemia (CLL) cells, but not normal B cells. The humanized antibody can directly kill CLL cells.
RESEARCH REPORT Michael Kaufman Targeting the bone marrow–specific extracellular matrix osteopontin may be an effective strategy to increase the efficacy of chemotherapy in patients with acute lymphocytic leukemia, according to the authors of a recent study.
REVIEW ARTICLE Shadi Latta, et al;ONCOLOGY Vol. 27 No. 2 In this review, we critically analyze clinical trials that were specifically designed for the very elderly, and we discuss the challenges encountered by investigators who are conducting studies in this patient population.
Up to 20% of all primary CNS lymphoma (PCNLS) patients are aged 80 years or older, yet data are limited on how best to treat this rapidly growing population. Despite demographic pressures and the proven efficacy of methotrexate (MTX)-based regimens, automatic de-escalation of care based on age is standard practice outside of tertiary care centers. We performed a retrospective review of all PCNSL patients aged 80 years or older treated at Memorial Sloan-Kettering Cancer Center from 1993 to 2011. Demogr
The Notch pathway is dysregulated and a potential target in glioblastoma multiforme (GBM). Currently available Notch inhibitors block -secretase, which is necessary for Notch processing. However, Notch is first cleaved by α-secretase outside the plasma membrane, via a disintegrin and metalloproteinase–10 and –17. In this work, we used a potent α-secretase inhibitor (ASI) to test inhibition of glioblastoma growth and inhibition of Notch and of both novel and known Notch targets.
This study investigated the prevalence and the prognostic relevance of the 2 known telomere maintenance mechanisms (TMMs), telomerase activity (TA) and alternative lengthening of telomeres (ALT), in malignant peripheral nerve sheath tumors (MPNST). In 57 specimens from 49 patients with MPNST (35 sporadic, 14 neurofibromatosis type 1-related), TA was determined using the telomeric repeat amplification protocol, and ALT was detected by assaying ALT-associated promyelocytic leukemia bodies (APB) and term
Treatment-related myelodysplastic syndrome (t-MDS) and treatment-related acute myelogenous leukemia (t-AML) represent rare secondary events in patients with primary tumors of the nervous system and predominantly affect those treated with alkylating agents or topoisomerase II inhibitors. Temozolomide has become the standard chemotherapeutic agent for malignant gliomas. The emergence of this alkylating agent with little acute toxicity or cumulative myelosuppression has led to off-label protracted chemot
The diagnosis of primary central nervous system lymphoma (PCNSL) by radiographical examination is often difficult because of its similarity to other brain tumors. To test whether interleukin-10 (IL-10) and IL-6 can be used to distinguish PCNSL from other brain tumors that are radiographically similar, cerebrospinal fluid (CSF) levels of IL-10 and IL-6 were measured in 66 patients with intracranial tumors (PCNSLs: 26 cases; other brain tumors: 40 cases). In the patients with PCNSLs, the median CSF leve
DLBCL of any stage remains a systemic disease with early hematogenous spread. Thus, arguments advocating the role of IFRT do not truly address disease biology, and all future efforts to cure patients will require improved systemic therapy.
If systemic treatment is effective enough to reliably control not only microscopic but also bulky disease, there will be little role for radiotherapy. And if systemic treatment cannot even reliably control microscopic disease, let alone macroscopic disease, there will be little role for radiotherapy, either. However, there are patients who fall into neither of these categories, and in them radiotherapy may well have a role.
