Inhibition of DNA methylation sensitizes glioblastoma for tumor necrosis factor-related apoptosis-inducing ligand-mediated destruction.
2005
AbstractLife expectancy of patients affected by glioblastoma multiforme is extremely low. The therapeutic use of tumor necrosis factor–related apoptosis-inducing ligand (TRAIL) has been proposed to treat this disease based on its ability to kill glioma cell lines in vitro and in vivo. Here, we show that, differently from glioma cell lines, glioblastoma multiforme tumors were resistant to TRAIL stimulation because they expressed low levels of caspase-8 and high levels of the death receptor inhibitor PED/PEA-15. Inhibition of methyltransferases by decitabine resulted in considerable up-regulation of TRAIL receptor-1 and caspase-8, down-regulation of PED/PEA-15, inhibition of cell growth, and …
Second primary malignancies in patients treated for gastric mucosa-associated lymphoid tissue lymphoma.
2017
IF 2.755; International audience; To assess the risk of second primary malignancy (SPM) in patients with gastric mucosa-associated lymphoid tissue (MALT) Lymphoma (GML), we included 175 patients with GML in the present study. The incidence of SPM in the general population, used for reference, was determined from the French network of cancer registries. During the 1442.9 patient-years of follow-up, 29 patients were diagnosed with incident SPM, including five patients diagnosed with gastric cancer (20.1/1000 patient-years). An increased incidence of SPM was observed in patients with GML (standardized incidence ratios [SIR]: 1.71 [1.14-2.45]) compared to the general French population especiall…
Sustained telomere erosion due to increased stem cell turnover during triple autologous hematopoietic stem cell transplantation.
2007
Telomeres cap chromosomal ends and are shortened throughout a lifetime. Additional telomere erosion has been documented during conventional chemotherapy or hematopoietic stem cell transplantation. Previous studies of stem cell transplantation reported variable amounts of telomere shortening with inconsistent results regarding the persistence of telomere shortening. Here we have prospectively studied telomere length and proliferation kinetics of hematopoietic cells in aggressive non-Hodgkin lymphoma patients who underwent a four-course high-dose chemotherapy protocol combined with triple autologous stem cell transplantation. We observed sustained telomere shortening in hematopoietic cells af…
Prospective randomised trial of chemotherapy given before radiotherapy in childhood medulloblastoma. International society of paediatric oncology (SI…
1995
In a multicentre randomised clinical trial 364 children with biopsy proven medulloblastoma were randomly assigned to receive or not pre-radiotherapy chemotherapy. Children with total or subtotal removal of the tumour, no evidence of invasive brain stem involvement, and no evidence of metastatic disease either within or without the cranium were designated "low risk", those with gross residual tumour, evidence of invasive brain stem involvement or metastases in the central nervous system were designated "high risk". All children were prescribed 55 Gy to the tumour bearing area. "Low risk" children could be randomised to "standard" radiotherapy 35 Gy to the craniospinal axis or "reduced" dose …
Detection and clinical implications of a novel BCR-ABL1 E12A2 insertion/deletion in a CML patient expressing the E13A2 isoform
2019
Background/Aim: The Philadelphia chromosome is the most frequent cytogenetic abnormality in chronic myelogenous (CML). More than 95% of CML patients are diagnosed with the e13a2 or e14a2 BCR-ABL1 fusion transcripts while, in about 1% of these individuals, the break generates the e1a2 rearrangement. Furthermore, about 5% of CML patients are diagnosed with rare BCR-ABL1 fusion transcripts, such as e19a2, e8a2, e13a3, e14a3, e1a3 and e6a2. However, there is limited evidence concerning the clinical and prognostic implications of these infrequent oncogenic variants for CML patients receiving tyrosine kinase inhibitors (TKIs). Case Report: We describe a novel atypical e12a2 insertion/deletion (In…
Clinical significance of complex karyotype at diagnosis in pediatric and adult patients with de novo acute promyelocytic leukemia treated with ATRA a…
2019
Although additional cytogenetic abnormalities (ACA) do not affect the prognosis of patients with t(15;17) acute promyelocytic leukemia (APL), the role of a complex karyotype (CK) is yet to be clarified. We aimed to investigate the relationship of CK with relapse incidence in 1559 consecutive APL patients enrolled in three consecutive trials. Treatment consisted of AIDA induction followed by risk-adapted consolidation. A CK (CK) was defined as the presence of ≥2 ACA, and a very CK (CK+) as ≥3 ACA. Eighty-nine patients (8%) had a CK, of whom 41 (4%) had CK+. The 5-year cumulative incidence of relapse (CIR) in patients with CK was 18%, and 12% in those with <2 ACA (p=.09). Among patients wi…
Colorectal cancer stage at diagnosis in migrants versus non-migrants (KoMigra) : study protocol of a cross-sectional study in Germany
2014
Background: In Germany, about 20% of the total population have a migration background. Differences exist between migrants and non-migrants in terms of health care access and utilisation. Colorectal cancer is the second most common malignant tumour in Germany, and incidence, staging and survival chances depend, amongst other things, on ethnicity and lifestyle. The current study investigates whether stage at diagnosis differs between migrants and non-migrants with colorectal cancer in an area of high migration and attempts to identify factors that can explain any differences. Methods/Design: Data on tumour and migration status will be collected for 1,200 consecutive patients that have receive…
Acute and chronic hepatitis in childhood leukemia: a multicentric study from the Italian Pediatric Cooperative Group for Therapy of Acute Leukemia (A…
1985
The incidence of acute and chronic liver damage and its relation to hepatitis B virus (HBV) infection was evaluated in 164 consecutive children with acute leukemia seen in ten Italian hemato-pediatric units. Thirteen out of 164 children (7.9%) had acute hepatitis (AH) during treatment, while 8/90 (8.8%) showed an acute exacerbation of liver damage within 6 months after therapy withdrawal. Seven of the 13 children with AH while on therapy were HBsAg positive. In 12/13 cases, liver disease progressed to chronicity. Five of eight children who developed AH after completion of treatment were HBsAg positive. Eighty-nine patients (54.2%) developed biochemical evidence of chronic hepatitis during t…
Pretreatment quality of life and functional status assessment significantly predict survival of elderly patients with advanced non-small-cell lung ca…
2005
Purpose To study the prognostic value for overall survival of baseline assessment of functional status, comorbidity, and quality of life (QoL) in elderly patients with advanced non—small-cell lung cancer treated with chemotherapy. Patients and Methods Data from 566 patients enrolled onto the phase III randomized Multicenter Italian Lung Cancer in the Elderly Study (MILES) study were analyzed. Functional status was measured as activities of daily living (ADL) and instrumental ADL (IADL). The presence of comorbidity was assessed with a checklist of 33 items; items 29 and 30 of the European Organisation for Research and Treatment of Cancer (EORTC) core questionnaire QLQ-C30 (EORTC QLQ-C30) wer…
High dose inhalation interleukin-2 therapy for lung metastases in patients with malignant melanoma.
2000
BACKGROUND The lungs are a frequent site of metastasis in patients with melanoma, and this may cause respiratory problems in the terminal phase of the illness. Inhalation interleukin (IL)-2 therapy to the lung has been piloted and appears to be well tolerated. METHODS Twenty-seven patients were treated with single agent dacarbazine and concurrent high dose inhalation IL-2 36 million IU per day). The patients previously had progressed on chemotherapy, predominately dacarbazine-based regimens. Patients included those with American Joint Committee on Cancer Stage IV melanoma, predominately those with lung metastases, but patients with extrapulmonary metastases also were allowed on the study.
