Abstract A42: miR34a: A valuable indicator of differential outcome of Ewing sarcoma patients with complex functions
2014
Abstract The identification of reliable indicators of prognosis, which may allow the stratification of patients according to different risk at diagnosis isan important aspect of translational research in Ewing sarcoma (ES). In this paper, we validated our previous evidence showing how expression of miR34a in ES tumor samples at diagnosis was signficantly associated with tumor progression (Nakatani F. J Pathol 2012). Here we analyzed a different series of speciments derived from very controlled and homogeneously treated non-metastatic ES patients, and we compared evaluation of miR34a by RT-PCR using frozen samples with that obtained by in situ hybridization on paraffin-embedded samples . The…
Freedom from progression (FFP) by adding paclitaxel (T) to doxorubicin (A) followed by CMF as adjuvant or primary systemic therapy: 10-yr results of …
2013
537 Background: At the time the ECTO was designed in 1996, taxanes were only indicated for patients with metastatic breast cancer. However, paclitaxel and docetaxel were still to be tested in the adjuvant setting. In addition there was relatively scarce information on the comparative efficacy of neoadjuvant and adjuvant regimens. The ECTO trial was designed to evaluate the addition of paclitaxel to an anthracycline-based adjuvant regimen and to compare this combination with the same regimen given as primary systemic (neoadjuvant) therapy. Methods: A total of 1,355 women with operable breast cancer were randomized to one of three treatments: 1) surgery followed by adjuvant single agent doxo…
A polymorphism at the 3'-UTR region of the aromatase gene defines a subgroup of postmenopausal breast cancer patients with poor response to neoadjuva…
2009
Abstract Background Aromatase (CYP19A1) regulates estrogen biosynthesis. Polymorphisms in CYP19A1 have been related to the pathogenesis of breast cancer (BC). Inhibition of aromatase with letrozole constitutes the best option for treating estrogen-dependent BC in postmenopausal women. We evaluate a series of polymorphisms of CYP19A1 and their effect on response to neoadjuvant letrozole in early BC. Methods We analyzed 95 consecutive postmenopausal women with stage II-III ER/PgR [+] BC treated with neoadjuvant letrozole. Response to treatment was measured by radiology at 4th month by World Health Organization (WHO) criteria. Three polymorphisms of CYP19A1, one in exon 7 (rs700519) and two in…
Prognostic Potential Of The Pretherapeutic Tumor Oxygenation Status
2009
Hypoxia, a characteristic feature of locally advanced solid tumors, has emerged as a key factor of the tumor pathophysiome, since it can promote tumor progression and resistance to therapy. Independent of established prognostic parameters, such as clinical tumor stage, histology, histological grade and nodal status, hypoxia has been identified as an adverse prognostic factor for patient outcome. Studies of pretreatment tumor hypoxia involving direct assessment (polarographic oxygen tension measurements) have suggested a poor prognosis for patients with hypoxic tumors. These investigations indicate a worse disease-free survival for patients with hypoxic cancers of the uterine cervix or soft …
Nm-23-H1 expression does not predict clinical survival in colorectal cancer patients
2003
The gene Nm23, which encodes for a nucleoside diphosphate kinase, has been defined as a metastasis-suppressor gene because of the inverse correlation between its expression and the metastatic capacity of the tumor cells. For colorectal cancer, however, the findings are equivocal. The aim of our study was to assess, in 160 patients undergoing surgery for colorectal cancer (CRC), the expression of the Nm23-H1 protein and to evaluate its possible associations with traditional clinicopathologic variables, with DNA-ploidy and proliferative activity (S-phase fraction, SPF), and with disease-free and overall survival of patients. Nm23-H1 expressions were evaluated on paraffin-embedded tissue by im…
Recurrence of hepatocellular carcinoma after direct acting antiviral treatment for hepatitis C virus infection: Literature review and risk analysis
2018
Although studies suggest decreased incident hepatocellular carcinoma (HCC) after treatment with direct-acting antivirals (DAAs) for hepatitis C virus (HCV) infection, data are conflicting regarding risk and aggressiveness of recurrence in patients who have a history of treated HCC. This review analyses data available in literature in order to elucidate the impact of DAAs on the risk of HCC recurrence after successful treatment of the tumor. Overall 24 papers were identified. The available data cannot be considered definitive, but the initial alarmist data indicating an increased risk of recurrence have not been confirmed by most subsequent studies. The suggested aggressive pattern (rapid gr…
Natural history of malignant bone disease in renal cancer: final results of an Italian bone metastasis survey.
2013
BackgroundBone metastasis represents an increasing clinical problem in advanced renal cell carcinoma (RCC) as disease-related survival improves. There are few data on the natural history of bone disease in RCC.Patients and methodsData on clinicopathology, survival, skeletal-related events (SREs), and bone-directed therapies for 398 deceased RCC patients (286 male, 112 female) with evidence of bone metastasis were statistically analyzed.ResultsMedian time to bone metastasis was 25 months for patients without bone metastasis at diagnosis. Median time to diagnosis of bone metastasis by MSKCC risk was 24 months for good, 5 months for intermediate, and 0 months for poor risk. Median number of SR…
Systemic Inflammatory Markers and Oncologic Outcomes in Patients with High-risk Non-muscle-invasive Urothelial Bladder Cancer
2018
Background: Serum levels of neutrophils, platelets, and lymphocytes have been recognized as factors related to poor prognosis for many solid tumors, including bladder cancer (BC). Objective: To evaluate the prognostic role of the combination of the neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and lymphocyte/monocyte ratio (LMR) in patients with high-risk non–muscle-invasive urothelial BC (NIMBC). Design, setting, and participants: A total of 1151 NMIBC patients who underwent first transurethral resection of the bladder tumor (TURBT) at 13 academic institutions between January 1, 2002 and December 31, 2012 were included in this analysis. The median follow-up was 48 mo.…
Efficacy and safety of irinotecan-based chemotherapy for advanced colorectal cancer outside clinical trials: an observational study.
2010
Background: This prospective observational study in typical community-based outpatient clinics evaluated the efficacy and toxicity of weekly and biweekly irinotecan-based chemotherapies and their compatibility depending on age. Methods: 601 patients with advanced or metastatic colorectal cancer receiving first-, second-, or third-line irinotecanbased therapy were regularly analyzed for response and toxicity until the end of therapy. Results: The median age was 65 (28–87) years, approximately one-third of the patients were ≥70 years old. Of all patients, 405 were treated weekly and 68 biweekly. Median overall survival (OS) for first-line therapy was 26.5 months for the <70-year-old patients …
Lenalidomide Maintenance After Autologous Stem-Cell Transplantation in Newly Diagnosed Multiple Myeloma: A Meta-Analysis
2017
Purpose Lenalidomide maintenance therapy after autologous stem-cell transplantation (ASCT) demonstrated prolonged progression-free survival (PFS) versus placebo or observation in several randomized controlled trials (RCTs) of patients with newly diagnosed multiple myeloma (NDMM). All studies had PFS as the primary end point, and none were powered for overall survival (OS) as a primary end point. Thus, a meta-analysis was conducted to better understand the impact of lenalidomide maintenance in this setting. Patients and Methods The meta-analysis was conducted using primary-source patient-level data and documentation from three RCTs (Cancer and Leukemia Group B 100104, Gruppo Italiano Malatti…
