Kirsten ras mutations in patients with colorectal cancer: the 'RASCAL II' study

2001

Researchers worldwide with information about the Kirsten ras (Ki-ras) tumour genotype and outcome of patients with colorectal cancer were invited to provide that data in a schematized format for inclusion in a collaborative database called RASCAL (The Kirsten ras in-colorectal-cancer collaborative group). Our results from 2721 such patients have been presented previously and for the first time in any common cancer, showed conclusively that different gene mutations have different impacts on outcome, even when the mutations occur at the same site on the genome. To explore the effect of Ki-ras mutations at different stages of colorectal cancer, more patients were recruited to the database, whi…

The prognostic value of biological markers in paediatric Hodgkin lymphoma

2015

Abstract Background Many biological and inflammatory markers have been proposed as having a prognostic value at diagnosis of Hodgkin lymphoma (HL), but very few have been validated in paediatric patients. We explored the significance of these markers in a large population of 769 affected children. Patients and methods By using the database of patients enrolled in A.I.E.O.P. (Associazione Italiana di Emato-Oncologia Pediatrica) trial LH2004 for paediatric HL, we identified 769 consecutive patients treated with curative intent from 1st June 2004 to 1st April 2014 with ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine), or hybrid COPP/ABV (cyclophosphamide, vincristine, prednisone, pr…

Cabozantinib in Pretreated Patients with Metastatic Renal Cell Carcinoma with Sarcomatoid Differentiation: A Real-World Study

2021

Background: Renal cell carcinoma with sarcomatoid differentiation is a highly aggressive form of kidney cancer. Objective: We aimed to analyze the outcomes of patients treated with cabozantinib for metastatic renal cell carcinoma with sarcomatoid features. Methods: We retrospectively collected data from 16 worldwide centers. Overall survival and progression-free survival were analyzed using Kaplan–Meier curves. Cox proportional models were used for univariate and multivariate analyses. Results: We collected data from 66 patients with metastatic sarcomatoid renal cell carcinoma receiving cabozantinib as second-line (51%) or third-line (49%) therapy. The median progression-free survival from …

Specific TP53 and/or Ki-ras mutations as independent predictors of clinical outcome in sporadic colorectal adenocarcinomas: results of a 5-year Grupp…

2005

BACKGROUND: Although Ki-ras and TP53 mutations have probably been the genetic abnormalities most exhaustively implicated and studied in colorectal cancer (CRC) progression, their significance in terms of disease relapse and overall survival has not yet clearly been established. PATIENTS AND METHODS: A prospective study was carried out on paired tumor and normal colon tissue samples from a consecutive series of 160 previously-untreated patients, undergoing resective surgery for primary operable sporadic CRC. Mutations within the TP53 (exons 5-8) and Ki-ras (exon 2) genes were detected by PCR-SSCP analyses following sequencing. RESULTS: Mutation analyses of exons 5 to 8 of the TP53 gene showe…

Role of Kras Status in Patients with Metastatic Colorectal Cancer Receiving First-Line Chemotherapy plus Bevacizumab: A TTD Group Cooperative Study

2012

Background: In the MACRO study, patients with metastatic colorectal cancer (mCRC) were randomised to first-line treatment with 6 cycles of capecitabine and oxaliplatin (XELOX) plus bevacizumab followed by either single-agent bevacizumab or XELOX plus bevacizumab until disease progression. An additional retrospective analysis was performed to define the prognostic value of tumour KRAS status on progression-free survival (PFS), overall survival (OS) and response rates. Methodology/Principal Findings: KRAS data (tumour KRAS status and type of mutation) were collected by questionnaire from participating centres that performed KRAS analyses. These data were then cross-referenced with efficacy da…

Influence of molecular subgroups on outcome of acute myeloid leukemia with normal karyotype in 141 patients undergoing salvage allogeneic stem cell t…

2012

Based on molecular aberrations, in particular the NPM1 mutation (NPM1(mut)) and the FLT3 internal tandem duplication (Flt3-ITD), prognostic subgroups have been defined among patients with acute myeloid leukemia with normal karyotype. Whereas these subgroups are known to play an important role in outcome in first complete remission, and also in the indication for allogeneic stem cell transplantation, data are limited on their role after transplantation in advanced disease. To evaluate the role of molecular subgroups of acute myeloid leukemia with normal karyotype after allogeneic stem cell transplantation beyond first complete remission, we analyzed the data from 141 consecutive adults (medi…

Refining prognosis after trans-arterial chemo-embolization for hepatocellular carcinoma

2015

Background & aims To develop an individual prognostic calculator for patients with unresectable hepatocellular carcinoma (HCC) undergoing trans-arterial chemo-embolization (TACE). Methods Data from two prospective databases, regarding 361 patients who received TACE as first-line therapy (2000-2012), were reviewed in order to refine available prognostic tools and to develop a continuous individual web-based prognostic calculator. Patients with neoplastic portal vein invasion were excluded from the analysis. The model was built following a bootstrap resampling procedure aimed at identifying prognostic predictors and by carrying out a 10-fold cross-validation for accuracy assessment by means o…

A population-based study of adjuvant chemotherapy for stage-II and -III colon cancers.

2010

Summary Background Although clinical trials have demonstrated that adjuvant chemotherapy improves survival for stage-III colon cancer, the benefits remain controversial for stage-II lesions. The objective of the present study was to determine the extent to which adjuvant chemotherapy is used for patients with stage-II and -III colon cancers. Methods The study population comprised 1074 patients with stage-II and -III colon cancers diagnosed in 2000 in 12 French administrative districts and recorded in population-based cancer registries. Data were collected using a standardized procedure. Results Overall, 20.4% of patients with stage II and 61.9% with stage III received adjuvant chemotherapy.…

Immunohistochemical Expression of Ki-67 Antigen, Cox-2 and Bax/Bcl-2 in Prostate Cancer; Prognostic Value in Biopsies and Radical Prostatectomy Speci…

2005

Abstract Purposes: To elucidate the prognostic value of the immunohistochemical (IHC) expression of Bcl-2, Bax, Cox-2 and Ki-67 antigen in biopsy cores (C) and surgical specimens (SP) of prostate cancer (PC) and to determine the C to SP reproducibility. Material and methods: The IHC study was carried out in 91 patients operated by means of radical prostatectomy (RP) with available formalin-fixed paraffin-embedded material from both C and SP. Results: The IHC expression of Bcl-2 in C and SP was very low (5%). Bax was expressed in almost all the patients and did not show any prognostic value. We observed a good reproducibility between C and SP for all molecules except with Bax. In prostate C,…
