Distinct HR expression patterns significantly affect the clinical behavior of metastatic HER2+ breast cancer and degree of benefit from novel anti-HE…
2020
We analyzed data from 738 HER2‐positive metastatic breast cancer (mbc) patients treated with pertuzumab‐based regimens and/or T‐DM1 at 45 Italian centers. Outcomes were explored in relation to tumor subtype assessed by immunohistochemistry (IHC). The median progression‐free survival at first‐line (mPFS1) was 12 months. Pertuzumab as first‐line conferred longer mPFS1 compared to other first‐line treatments (16 vs. 9 months, p = 0.0001), regardless of IHC subtype. Median PFS in second‐line (mPFS2) was 7 months, with no difference by IHC subtype, but it was more favorable with T‐DM1 compared to other agents (7 vs. 6 months, p = 0.03). There was no PFS2 gain in patients with tumors expressing b…
Randomized phase III trial of adjuvant epirubicin followed by cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) versus CMF followed by epirubi…
2010
International audience; Adjuvant cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) have proven highly effective in rapidly proliferating breast cancer (RPBC). It has also been seen that sequential administration of doxorubicin and CMF is superior to their alternation, especially in indolent tumors. In a phase III study, we evaluated whether adjuvant epirubicin (E) followed by CMF is superior to the inverse sequence in RPBC. Patients with node-negative or 1-3 node-positive RPBC (Thymidine Labeling Index > 3% or histological grade 3 or S-phase > 10% or Ki67 > 20%) were randomized to receive E (100 mg/m i.v. d1, q21 days for 4 cycles) followed by CMF (600, 40, 600 mg/m i.v. d1 and 8, q2…
The EndoPredict score provides prognostic information on late distant metastases in ER+/HER2− breast cancer patients
2013
Background: ER þ/HER2 � breast cancers have a proclivity for late recurrence. A personalised estimate of relapse risk after 5 years of endocrine treatment can improve patient selection for extended hormonal therapy. Methods: A total of 1702 postmenopausal ER þ/HER2 � breast cancer patients from two adjuvant phase III trials (ABCSG6, ABCSG8) treated with 5 years of endocrine therapy participated in this study. The multigene test EndoPredict (EP) and the EPclin score (which combines EP with tumour size and nodal status) were predefined in independent training cohorts. All patients were retrospectively assigned to risk categories based on gene expression and on clinical parameters. The primary…
The natural history of breast carcinoma in patients withor = 10 metastatic axillary lymph nodes before and after the advent of adjuvant therapy: a mu…
2005
BACKGROUND The majority of patients with breast carcinoma with ≥ 10 metastatic axillary lymph nodes (ALNs) develop recurrent disease within 5 years from diagnosis. The purpose of the current study, performed retrospectively, was to characterize the natural history of this subset of patients, both before and after the advent of adjuvant anthracycline-based chemotherapy and tamoxifen. METHODS Retrospectively, patients with primary breast carcinoma (N = 882) with ≥ 10 metastatic ALNs, treated between 1954 and 1998, were selected from 3 institutions: The University of Texas M. D. Anderson Cancer Center (Houston, TX); the Institut Gustave Roussy (Villejuif, France); and Hospital Clinico Universi…
Dexamethasone desensitizes hepatocellular and colorectal tumours toward cytotoxic therapy
2005
The glucocorticoid dexamethasone is frequently used as co-treatment in cytotoxic cancer therapy, e.g. to prevent nausea, to protect normal tissue or for other reasons. While the potent pro-apoptotic properties and the supportive effects of glucocorticoids to tumour therapy in lymphoid cells are well studied, the impact to cytotoxic treatment of colorectal and hepatocellular carcinoma is unknown. We tested apoptosis-induction, viability, tumour growth and protein expression using 8 established cell lines, 18 surgical specimen and a xenograft on nude mice. In the presence of dexamethasone we found strong inhibition of apoptosis in response to 5-FU, cisplatin, gemcitabine or gamma-irradiation,…
How we treat metastatic colorectal cancer.
2020
Colorectal cancer is the second leading cause of cancer-related death worldwide. About 20% of patients suffer from metastatic disease at diagnosis, while about one-third of patients treated with curative intent relapsed. In these patients, an accurate staging allows to plan a treatment strategy within a multidisciplinary team in order to achieve predefined goals. Patient's clinical features, tumour characteristics and molecular profile (RAS/BRAF and microsatellite instability (MSI) status) should be considered during the treatment choice. Combination of chemotherapy (fluoropyrimidines, oxaliplatin and irinotecan) plus biological agents (antiepidermal growth factor receptor or antiangiogenic…
Zymographic detection and clinical correlations of MMP-2 and MMP-9 in breast cancer sera.
2004
Matrix metalloproteinases, in particular the gelatinases MMP-2 and MMP-9, have received great attention in recent years as putative tumour markers for clinical applications. The main reason for the observed interest is their easy detection in body fluids. Moreover, recent evidence has shown multiple functions of MMPs, rather than simply degrading ECM, which include the mobilisation of growth factors and processing of surface molecules. Several authors have reported increased levels of MMPs in a number of cancers, but clinical correlations in breast cancer are still fragmentary. Thus, the aim of the present research was to investigate the activity levels of circulating gelatinases in the ser…
Natural history of malignant bone disease in non-small cell lung cancer: Preliminary results of a multicenter bone metastasis survey
2013
e19084 Background: Bone metastases represent an increasing clinical problem in advanced non-small cell lung cancer (NSCLC) as disease-related survival improves. This is a multicenter, retrospective survey aimed to explore the impact of bone involvement in this severe, life-threatening disease. Methods: Data on clinicopathology, skeletal outcomes, skeletal-related events (SREs), and bone-directed therapies for 421 deceased NSCLC patients (48.6% aged >66 years) with evidence of bone metastasis were statistically analyzed. Results: ECOG performance status at diagnosis of NSCLC was 0 in 41.4% of patients, 1 in 42.8% and 2 in 13.9%. The most frequent stage at diagnosis was IV (76.8%). Adenoc…
Evaluation of survival across several treatment lines in metastatic colorectal cancer: Analysis of the FIRE-3 trial (AIO KRK0306).
2017
Abstract Background We explored the impacts of sequential application of various treatment lines on survival kinetics. Therefore, differences in overall survival (OS) observed in FIRE-3 were investigated in the context of time and exposure to applied treatment. Patients and methods OS analyses (stratified by treatment with FOLFIRI plus either cetuximab or bevacizumab) were performed according to time intervals as well as using a Cox model to define changes of hazard ratio (HR) over time. Results The fraction of patients with systemic treatment and time on treatment markedly decreases over treatment lines and time. OS evaluation by a Cox model indicated a trend towards a non-proportional haz…
Molecular markers and biological targeted therapies in metastatic colorectal cancer: expert opinion and recommendations derived from the 11th ESMO/Wo…
2010
The article summarizes the expert discussion and recommendations on the use of molecular markers and of biological targeted therapies in metastatic colorectal cancer (mCRC), as well as a proposed treatment decision strategy for mCRC treatment. The meeting was conducted during the 11th ESMO/World Gastrointestinal Cancer Congress (WGICC) in Barcelona in June 2009. The manuscript describes the outcome of an expert discussion leading to an expert recommendation. The increasing knowledge on clinical and molecular markers and the availability of biological targeted therapies have major implications in the optimal management in mCRC. 21 Suppl 6 vi1 10
