An aCGH classifier derived from BRCA1-mutated breast cancer and benefit of high-dose platinum-based chemotherapy in HER2-negative breast cancer patients.

BACKGROUND: Breast cancer cells deficient for BRCA1 are hypersensitive to agents inducing DNA double-strand breaks (DSB), such as bifunctional alkylators and platinum agents. Earlier, we had developed a comparative genomic hybridisation (CGH) classifier based on BRCA1-mutated breast cancers. We hypothesised that this BRCA1-like(CGH) classifier could also detect loss of function of BRCA1 due to other causes besides mutations and, consequently, might predict sensitivity to DSB-inducing agents. PATIENTS AND METHODS: We evaluated this classifier in stage III breast cancer patients, who had been r

In studies including patients with low recurrence risk, no advantage for BCG was found. Clinical trials showed no superiority of BCG i …

Perioperative management after high-dose chemotherapy with autologous or allogeneic hematopoietic stem cell transplantation for pediatric solid tumors.

INTRODUCTION: An increasing number of children with advanced malignancies have recently received high-dose chemotherapy (HDC) with hematopoietic stem cell transplantation (HSCT), followed by surgery. In this study, we reviewed our experience with surgery after HDC and autologous (auto) or allogeneic (allo) HSCT to elucidate the problems associated with this treatment and establish the optimum surgical management strategy. PATIENTS AND METHODS: We retrospectively reviewed the cases of 24 children with advanced malignancy treated with HDC and HSCT before tumor resection at our institution. The

Serial urinary IL-2, IL-6, IL-8, TNFalpha, UBC, CYFRA 21-1 and NMP22 during follow-up of patients with bladder cancer receiving intravesical BCG.

BACKGROUND: We evaluated the potential role of serial preinstillation levels of several interleukins, TNFalpha and urinary tumor markers to monitor patients with bladder cancer receiving intravesical BCG. PATIENTS AND METHODS: 121 urine samples were collected from: patients with bladder cancer treated with BCG (group 1); patients with bladder cancer receiving other intravesical treatment (group 2) and patients with urinary tract infections (group 3). Cytokines [IL-2, IL6 and [L8] and TNFalpha and urinary tumor markers [UBC, CYFRA 21-1 and NMP22] were measured by immunoassays. RESULTS: In 3 o

Treatment options in primary Ewing's sarcoma of the spine: report of seven cases and review of the literature.

Primary Ewing's sarcoma of the spine is reviewed, and seven cases are presented. Ewing's sarcoma of the spine is a rare condition that appears with a clinical triad of local pain, neurological deficit, and a palpable mass. The clinical picture, imaging characteristics, and management are discussed. The definitive management of Ewing's sarcoma of the spine, as in other locations, could include three main modalities: surgery, radiotherapy, and combination chemotherapy. In the presence of acute neurological decompensation, decompressive surgery via an appropriate approach should be performed. Bec

Prognostic value of persistent node involvement after neoadjuvant chemotherapy in patients with operable breast cancer.

Neoadjuvant chemotherapy is able to reduce the size of the majority of breast tumours and down-stage axillary-node status. The aim of this study was to assess the prognostic value of persistent node involvement after neoadjuvant chemotherapy. A total of 488 patients with T2-T3, N0-N1 breast cancer treated by neoadjuvant chemotherapy followed by tumour excision and axillary lymph-node dissection between 1981 and 1992 were selected from the Institut Curie database. Median follow-up was 7 years. Overall objective response rate before local treatment was 52% and breast tumour size was reduced in 8

High-dose chemotherapy and hematopoietic stem cell rescue for breast cancer: experience in California.

The role of high-dose chemotherapy (HDCT) and autologous hematopoietic stem cell rescue in breast cancer is still controversial. We analyzed the outcomes of 1111 consecutive patients with histologically proven breast cancer who underwent HDCT at 5 major California medical centers. The overall treatment-related mortality (TRM) was 2.3%. TRM was not influenced by disease stage or the HDCT regimen delivered, but it was influenced by hematopoietic graft source. The TRM was 6.1% when bone marrow with or without blood stem cells was used, but only 1.4% when blood stem cells alone were used (P < .001

Treatment-induced leukoencephalopathy in primary CNS lymphoma: a clinical and autopsy study.

BACKGROUND: Treatment-related leukoencephalopathy is the leading toxicity after successful treatment of primary CNS lymphoma (PCNSL). Its mechanism is poorly understood and there are no autopsy data available on such patients. METHODS: From a database of immunocompetent patients with PCNSL diagnosed between 1985 and 2001, the authors identified five autopsied patients who died of leukoencephalopathy. The authors reviewed their clinical records, MRI, and autopsy findings. RESULTS: The median age was 74 years (range 41 to 79) at PCNSL diagnosis. Symptoms of neurotoxicity developed a median of

Rituximab improves the efficacy of high-dose chemotherapy with autograft for high-risk follicular and diffuse large B-cell lymphoma: a multicenter Gruppo Italiano Terapie Innnovative nei linfomi survey.

PURPOSE: To investigate the impact of adding rituximab to intensive chemotherapy with peripheral-blood progenitor cell (PBPC) autograft for high-risk diffuse large B-cell lymphoma (DLB-CL) and follicular lymphoma (FL). PATIENTS AND METHODS: Data were collected from 10 centers associated with Gruppo Italiano Terapie Innnovative nei Linfomi for 522 patients with DLB-CL and 223 patients with FL (median age, 47 years) who received the original or a modified high-dose sequential (HDS) chemotherapy regimen. HDS was delivered to 396 patients without (R-) and to 349 patients with (R+) rituximab; 154

Safety and efficacy of a continuous infusion, patient controlled anti-emetic pump to facilitate outpatient administration of high-dose chemotherapy.

We evaluated the combination of diphenhydramine, lorazepam, and dexamethasone delivered as a continuous i.v. infusion via an ambulatory infusion pump with patient-activated intermittent dosing (BAD pump) for prevention of acute and delayed nausea/vomiting in patients receiving high-dose chemotherapy (HDC) for peripheral blood progenitor cell (PBPC) mobilization (MOB) or prior to autologous PBPC rescue. The BAD pump was titrated to patient response and tolerance, and continued until the patient could tolerate oral anti-emetics. Forty-four patients utilized the BAD pump during 66 chemotherapy co

Severe infections after single umbilical cord blood transplantation in adults with or without the co-infusion of CD34+ cells from a third-party donor: results of a multicenter study from the Grupo Español de Trasplante Hematopoyético (GETH).

BACKGROUND: Umbilical cord blood transplantation (CBT) is an established alternative source of stem cells in the setting of unrelated transplantation. When compared with other sources, single-unit CBT (sCBT) is associated with a delayed hematologic recovery, which may lead to a higher infection-related mortality (IRM). Co-infusion with the sCBT of CD34+ peripheral blood stem cells from a third-party donor (TPD) (sCBT + TPDCD34+) has been shown to markedly accelerate leukocyte recovery, potentially reducing the IRM. However, to our knowledge, no comparative studies have focused on severe infect

Stromal damage as consequence of high-dose chemo/radiotherapy in bone marrow transplant recipients.

Bone marrow transplant (BMT) relies on the engraftment of donor hemopoietic precursors in the host marrow space. Colony forming units-fibroblasts (CFU-f), the precursor compartment for the osteogenic lineage, are essential to hemopoietic stem cell survival, proliferation and differentiation. We have studied CFU-f in donors (aged 5 months to 62 years) and in patients who had received allogeneic BMT (aged 2 months to 63 years). In donor marrows we found an inverse correlation between CFU-f frequency and age. In BMT recipients CFU-f frequencies were reduced by 60%-90% (p < 0.05) and the numbers d

Conventional chemotherapy comprised four ddAC cycles, followed by four cycles of intravenous carboplatin area under the curve 6 eve …

[Intensive chemotherapy in the treatment of patients with metastatic breast cancer].

PURPOSE: Phase II study with intensive chemotherapy and autologous stem cells support in patients with metastatic breast cancer. METHODS: Forty-nine patients were treated with high-doses of two cytotoxic drugs and support with stem cells obtained from several leukapheresis without movilitation. The cells were reinfused forty-eight hours after finishing the administration of chemotherapy. RESULTS: Twenty-one patients (47%, CI-95%: 32.4-63.3%) achieved a complete remission. The objective responses rate was 73% (CI-95%: 57.2-85%). Overall and progression-free survival up to 4 years were 31% and

Amsacrine combined with etoposide and high-dose methylprednisolone as salvage therapy in acute lymphoblastic leukemia in children.

In a retrospective analysis of 24 children with refractory or multiply relapsed acute lymphoblastic leukemia (ALL), a salvage regimen comprising amsacrine, etoposide, and high-dose methylprednisolone AEP achieved a significant treatment response in 11 of 19 evaluable patients (8 complete and 3 partial remissions). Five of 9 AEP-responsive patients who underwent subsequent stem cell transplantation are alive (median follow-up: 43 months; range 10 to 91). The load of minimal residual disease prior to transplantation appears to be predictive for outcome in this very poor-prognosis subgroup of ALL

Safety and feasibility of outpatient autologous stem cell transplantation in pediatric patients with primary central nervous system tumors.

High-dose chemotherapy with autologous hematopoietic stem cell transplantation (autoHSCT) is a well-established treatment for pediatric central nervous system (CNS) tumors. Given the risks of toxicity and infection, pediatric autoHSCT has been historically performed on hospitalized children. As our practice evolved, some patients were transplanted as outpatients. We performed a retrospective cohort analysis of 37 patients who received 90 transplant procedures (49 outpatient and 41 inpatient) at Children's Hospital Colorado. The most common primary diagnosis was medulloblastoma (51.4%). Of the
