The humoral immune system has a key prognostic impact in node-negative breast cancer.
2008
Abstract Estrogen receptor (ER) expression and proliferative activity are established prognostic factors in breast cancer. In a search for additional prognostic motifs, we analyzed the gene expression patterns of 200 tumors of patients who were not treated by systemic therapy after surgery using a discovery approach. After performing hierarchical cluster analysis, we identified coregulated genes related to the biological process of proliferation, steroid hormone receptor expression, as well as B-cell and T-cell infiltration. We calculated metagenes as a surrogate for all genes contained within a particular cluster and visualized the relative expression in relation to time to metastasis with…
Doxorubicin-docetaxel sequential schedule: results of front-line treatment in advanced breast cancer.
2002
<i>Objective:</i> We conducted a multi-institutional phase II study to evaluate the tolerability and activity of a sequential schedule of treatment with doxorubicin and docetaxel in chemotherapy-naive women with advanced breast cancer. <i>Methods:</i> A total of 73 patients with PS (ECOG) 0–2, aged <70 years and adequate bone marrow, renal, liver and cardiac functions were included in the study (13 stage III B and 60 stage IV). The schedule of administration was doxorubicin 50 mg/m<sup>2</sup> by intravenous (i.v.) 30 min injection on day 1 followed the day after by docetaxel 75 mg/m<sup>2</sup>, by i.v. 60 min infusion. Cycles were repeate…
Identification of Biomarkers Including 18FDG-PET/CT for Early Prediction of Response to Neoadjuvant Chemotherapy in Triple-Negative Breast Cancer.
2015
Abstract Purpose: To investigate the value of the metabolic tumor response assessed with 18F-fluorodeoxyglucose positron emission tomography (FDG-PET), compared with clinicobiologic markers to predict pathologic complete response (pCR) to neoadjuvant chemotherapy (NAC) in women with triple-negative breast cancer (TNBC). Experimental Design: Fifty consecutive women with TNBC and an indication for NAC were prospectively included. Different pretreatment clinical, biologic, and pathologic biomarkers, including SBR grade, the Ki-67 proliferation index, androgen receptor expression, EGF receptor (EGFR), and cytokeratin 5/6 staining, were assessed. Tumor glucose metabolism at baseline and its chan…
Prognostic impact of phosphorylated HER-2 in HER-2+ primary breast cancer.
2011
Abstract Purpose. Tyrosine 1248 is one of the autophosphorylation sites of human epidermal growth factor receptor (HER)-2. We determined the prognostic value of the expression level of tyrosine 1248–phosphorylated HER-2 (pHER-2) in patients with HER-2+ primary breast cancer using a reverse-phase protein array. Patients and Methods. The optimal cutoff value of pHER-2 for segregating disease-free survival (DFS) was determined by receiver operating characteristic (ROC) curve analysis. Five-year DFS for pHER-2 expression level was estimated with the Kaplan-Meier method using both derivation (n = 162) and validation (n = 227) cohorts. Results. Of the 162 patients in the derivation cohort, 26 had…
Long-term outcomes in stage IIIB breast cancer patients who achieved less than a pathological complete response (pCR) after primary chemotherapy.
2009
Abstract Learning Objectives After completing this course, the reader will be able to: Summarize the main risk factors for relapse in patients with T4 breast cancer after neoadjuvant chemotherapy.Evaluate the role of hormone receptors and HER-2 as determinants of risk of relapse after neoadjuvant treatment.Compare the difference in outcomes between patients who achieve less than pCR in relation to receptor status. This article is available for continuing medical education credit at CME.TheOncologist.com. Purpose. Pathological complete response (pCR) to primary chemotherapy is the main determinant for improved disease-free survival (DFS) and overall survival (OS). The primary endpoints of ou…
HER2 amplification in recurrent breast cancer following breast-conserving therapy correlates with distant metastasis and poor survival.
2005
The authors analyzed the HER2 status in early-stage nonrecurrent and recurrent breast cancer groups following breast-conserving treatment. Retrospective analyses of a group of 36 invasive early breast cancer (IBC) patients who developed a local recurrence as a first event and of a random control group of 69 IBC patients were made. HER2 status was assessed by the HercepTest and fluorescence in situ hybridization. The Kaplan-Meier proportional log-rank test was used to study the impact of the biological factors on the metastasis-free interval (MFI) and the overall survival (OS). The Cox proportional hazards model, using stepwise selection was performed to identify the independent predictors o…
Neoadjuvant therapy for breast cancer
2019
Objective: To evaluate the frequency of neoadjuvant therapy (NT) in women with stage I–III breast cancer in Italy and whether it is influenced by biological characteristics, screening history, and geographic area. Methods: Data from the High Resolution Study conducted in 7 Italian cancer registries were used; they are a representative sample of incident cancers in the study period (2009–2013). Included were 3546 women aged <85 years (groups <50, 50–69, 70–64, and 75+) with stage I–III breast cancer at diagnosis who underwent surgery. Women were classified as receiving NT if they received chemotherapy, target therapy, and/or hormone therapy before the first surgical treatment. Logistic…
Adjuvant Tamoxifen Plus Ovarian Function Suppression Versus Tamoxifen Alone in Premenopausal Women With Early Breast Cancer: Patient-Reported Outcome…
2016
Purpose The Suppression of Ovarian Function trial showed improved disease control for tamoxifen plus ovarian function suppression (OFS) compared with tamoxifen alone for the cohort of premenopausal patients who received prior chemotherapy. We present the patient-reported outcomes. Patients and Methods The quality-of-life (QoL) analysis includes 1,722 of 2,045 premenopausal patients with hormone receptor–positive breast cancer randomly assigned to receive adjuvant treatment with 5 years of tamoxifen plus OFS or tamoxifen alone. Chemotherapy use before enrollment was optional. Patients completed a QoL form consisting of global and symptom indicators at baseline, every 6 months for 24 months, …
Excess risk of subsequent malignant neoplasms in adolescent and young adult cancer survivors: Results from the first Italian population-based cohort
2022
Background: Evidence about late effects in adolescent and young adult (AYA) cancer survivors is scarce. This study assessed the risk of subsequent malignant neoplasms (SMNs) to identify the most common SMNs to be considered in follow-up care. Methods: Population-based cancer registries retrospectively identified first primary tumors (between 1976 and 2013) and SMNs in AYAs (15-39 years old at their cancer diagnosis). AYA cancer survivors were those alive at least 5 years after their first cancer diagnosis. The excess risk of SMNs was measured as standardized incidence ratios (SIRs) and absolute excess risk together with the cumulative incidence of SMNs. Results: The cohort included 67,692 A…
Cryotherapy for liver tumors: current status, perspectives, clinical results, and review of literature.
2004
Cryotherapy has gained importance as a locally ablative treatment option for patients with non-resectable liver tumors, especially metastases from colorectal cancer. We have used this technique since 1996 for the treatment of 77 patients with malignant liver tumors. Patient data was prospectively recorded and follow-up was until September 2002 or death. Fifty-five patients had colorectal cancer liver metastases, 16 metastases from other primaries and 6 had hepatoma. Forty patients had cryotherapy only and 37 had an additional liver resection. Morbidity and mortality were 22% and 1.3%, respectively. In 68% of patients with colorectal liver metastases and an elevated serum carcinoembryonic a…
