BACKGROUND: Pretransplant functional imaging (FI), particularly a negative positron emission tomography (PET), is a strong predictor of outcome in adults with relapsed or refractory Hodgkin lymphoma (HL), but data in pediatrics are limited. METHODS: The medical records of 49 consecutive pediatric patients, who received autologous transplant at a single institution, were retrospectively analyzed. All patients had either gallium or PET scan before transplant and were conditioned with carmustine, etoposide, cytarabine, and melphalan (BEAM)...

For newly diagnosed glioblastomas treated with resection in association with the standard combined chemoradiotherapy, the impact of Carmustine wafer implantation remains debated regarding postoperative infections, quality of life, and feasibility of adjuvant oncological treatments. To assess together safety, tolerance and efficacy of Carmustine wafer implantation and of extent of resection for glioblastoma patients in real-life experience. Observational retrospective monocentric study including 340 consecutive adult patients with a newly diagnosed supratentorial glioblastoma who underwent surgical resection with (n = 123) or without (n = 217) Carmustine wafer implantation as first-line oncological treatment...

BACKGROUND: The prognosis of young patients with diffuse large B-cell lymphoma at high risk (age-adjusted International Prognostic Index [aa-IPI] score 2 or 3) treated with R-CHOP (rituximab, cyclophosphamide, vincristine, doxorubicin, and prednisone) is poor. The aim of this study was to investigate the possible benefit of intensification with high-dose chemotherapy and autologous stem-cell transplantation as part of first-line treatment in these patients. METHODS: We did a multicentre, open-label, randomised, controlled, phase 3 trial with a 2 × 2 factorial design to compare, at two different R-CHOP dose levels, a full course of rituximab-dose-dense chemotherapy (no transplantation group) versus an abbreviated course of rituximab-dose-dense chemotherapy followed by consolidation with R-MAD (rituximab plus high-dose cytarabine plus mitoxantrone plus dexamethasone) and high-dose BEAM chemotherapy (carmustine, etoposide, cytarabine, and melphalan) plus autologous stem-cell transplantation (transplantation group) in young patients (18-65 years) with untreated high-risk diffuse large B-cell lymphoma (aa-IPI score 2-3)...

Epigenetic deregulation is increasingly being recognized as a hallmark of cancer. Recent studies have identified many new epigenetic biomarkers, some of which are being introduced into clinical practice for diagnosis, molecular classification, prognosis or prediction of response to therapies. O-6-methylguanine-DNA methyltransferase gene is the most clinically advanced epigenetic biomarker as it predicts the response to temozolomide and carmustine in gliomas. Therefore, epigenomics may represent a novel and promising tool for precision medicine, and in particular, the detection of epigenomic biomarkers in liquid biopsies will be of great interest for monitoring diseases in patients...

To investigate safety and efficacy of high-dose chemotherapy followed by autologous stem cell transplantation (HCT-ASCT) in relapsed/refractory (r/r) primary CNS lymphoma (PCNSL). We conducted a single-arm multicentre study for immunocompetent patients (<66 years) with PCNSL failing high-dose methotrexate (HD-MTX) based chemotherapy. Induction consisted of 2 courses of rituximab (375 mg/m(2)), high-dose cytarabine (2 × 3 g/m(2)) and thiotepa (40 mg/m(2)) with collection of stem cells in between. Conditioning for HCT-ASCT consisted of rituximab 375 mg/m(2), carmustine 400 mg/m(2) and thiotepa (4 × 5 mg/kg)...

Carmustine wafers (CW) were approved in Japan for newly diagnosed and recurrent malignant gliomas during 2013. The ventricle is often opened during surgery to achieve maximum resection. While not generally recommended in such situations, CW might be safely achieved by occluding an opened ventricle using gelform or collagen sheets. However, whether CW implantation actually confers a survival benefit for patients who undergo surgery with an open ventricle to treat glioblastoma remains unclear. Clinical, imaging, and survival data were collected in this multicenter retrospective study of 122 consecutive patients with newly diagnosed glioblastoma to determine adverse events and efficacy...

Relapse remains the most common cause of treatment failure in patients receiving autologous stem cell transplantation (ASCT) for follicular lymphoma (FL). The aim of this study was to evaluate the effect of adding radioimmunotherapy or rituximab (R) to BEAM (carmustine, etoposide, ara-c, melphalan) high-dose therapy for ASCT in patients with relapsed FL. Using the European Society for Blood and Marrow Transplantation registry, we conducted a cohort comparison of BEAM (n=1973), Zevalin-BEAM (Z-BEAM) (n=207) and R-BEAM (n=179) and also a matched-cohort analysis of BEAM vs Z-BEAM including 282 and 154 patients, respectively...

High-dose rituximab (HD-R) combined with carmustine, cytarabine, etoposide and melphalan (BEAM) and autologous stem cell transplant (ASCT) was effective and tolerable in a single-arm prospective study of relapsed aggressive B-cell non-Hodgkin lymphoma (R-NHL). We performed a randomized phase 2 study comparing HD-R versus standard-dose rituximab (SD-R) in R-NHL. Ninety-three patients were randomized to HD-R (1000 mg/m(2) ) (n = 42) or SD-R (375 mg/m(2) ) (n = 51) administered on post-transplant days +1 and +8, using a Bayesian adaptive algorithm...

BACKGROUND: To assess the influence of molecular markers with potential prognostic value to groups of patients with newly diagnosed glioblastoma patients were examined: group A with 36 patients (surgical resection plus standard combined chemoradiotherapy) and group B with 36 patients (surgical resection, standard combined chemoradiotherapy plus carmustine wafer implantation). Our aim was to determine chromosomal alterations, methylation status of MGMT, p15, and p16 (CDKN2A) in order to analyse the influence on patient survival time as well as radio- and chemotherapy responses...

Resistance to conventional therapies and frequent recurrence are the major obstacles to the treatment of high-grade gliomas, including glioblastoma. Thus, the development of new therapeutic strategies to overcome these obstacles is necessary to improve the treatment outcomes. In this study, we found that verapamil, a pan-adenosine triphosphate-binding cassette transporter and L-type voltage-dependent calcium channel inhibitor, sensitized U87MG glioma cells to carmustine- and irradiation-induced senescence. Furthermore, our results indicated that verapamil treatment, in combination with carmustine and irradiation, rendered U87MG glioma cells and several patient-derived glioma stem cells more sensitive to therapy-induced senescence than individual or dual-combination treatments...

Although aberrant androgen receptor (AR) signaling is a central mechanism for castration resistant prostate cancer (CRPC) progression, AR-independent growth signaling is also present in CRPC. The current therapeutic options for patients with CRPC are limited and new drugs are desperately needed to eliminate these crucial growth signaling pathways. We have previously shown that combination of carmustine and selenite effectively induces apoptosis and growth inhibition by targeting AR and AR-variants in CRPC cells...

The impact of age at diagnosis on outcomes of patients with Hodgkin lymphoma (HL) undergoing autologous hematopoietic transplantation (auto-HCT) is unclear. We retrospectively evaluated the impact of age on outcomes of 310 consecutive patients with relapsed/refractory HL who underwent auto-HCT between January 1996 and December 2010 with carmustine, etoposide, cytarabine, and melphalan conditioning therapy. Patients were stratified into ≤ 55 and >55-year-age groups based on age at diagnosis. At a median follow-up of 80 (range, 1 to 180) months, progression-free survival was similar between both age groups...

According to the guidelines proposed by the National Comprehensive Cancer Network, early-stage Mycosis Fungoides (MF) should be treated with skin-directed therapies such as topical steroids or retinoids, topical chemotherapy (carmustin and nitrogen mustard), photochemotherapy, and superficial radiotherapy. Patients with refractory lesions to these therapeutic options are particularly challenging. Photodynamic Therapy (PDT) has been approved to treat cutaneous neoplastic and pre-neoplastic lesions such as superficial basal cell carcinoma, Bowen disease and actinic keratosis...

The diverse responses of different cancers to treatments such as photodynamic therapy of cancer (PDT) have fueled a growing need for reliable predictive markers for treatment outcome. In the present work we have studied the differential response of two phenotypically and genotypically different breast adenocarcinoma cell lines, MCF7 and MDA-MB-231, to hypericin PDT (HYP-PDT). MDA-MB-231 cells were 70% more sensitive to HYP PDT than MCF7 cells at LD50. MCF7 were found to express a substantially higher level of glutathione peroxidase (GPX4) than MDA-MB-231, while MDA-MB-231 differentially expressed glutathione-S-transferase (GSTP1), mainly used for xenobiotic detoxification...

Purpose Proton magnetic resonance spectroscopy (MRS) of the brain can detect 2-hydroxyglutarate (2HG), the oncometabolite produced in neoplasms harboring a mutation in the gene coding for isocitrate dehydrogenase ( IDH). We conducted a prospective longitudinal imaging study to determine whether quantitative assessment of 2HG by MRS could serve as a noninvasive clinical imaging biomarker for IDH-mutated gliomas. Patients and Methods 2HG MRS was performed in 136 patients using point-resolved spectroscopy at 3 T in parallel with standard clinical magnetic resonance imaging and assessment...

Glioblastoma is the most frequent and devastating primary brain tumor. Surgery followed by radiotherapy with concomitant and adjuvant chemotherapy is the standard of care for patients with glioblastoma. Chemotherapy is ineffective, because of the low therapeutic levels of pharmaceuticals in tumor tissues and the well-known tumor-cell resistance to chemotherapy. Therefore, we developed bilayered poly(d,l)-lactide-co-glycolide nanofibrous membranes that enabled the sequential and sustained release of chemotherapeutic and antiangiogenic agents by employing an electrospinning technique...

There is no standard therapy for recurrent anaplastic glioma (AG). Salvage therapies include alkylator-based chemotherapy, re-resection with or without carmustine implants, re-irradiation and bevacizumab. Bendamustine is a novel bifunctional alkylator with CNS penetration never previously evaluated in AG. Assess response and toxicity of bendamustine in recurrent AG in a phase II trial. Adults with radiation and temozolomide refractory recurrent AG were treated with bendamustine. A cycle of bendamustine was defined as two consecutive days of treatment (100 mg/m(2)/day) administered once every 4 weeks...
