Hippocampal dose during Linac-based stereotactic radiotherapy for brain metastases: An observational study

2017

Abstract Introduction Aim of the present study is to evaluate homolateral and contralateral hippocampus (H-H, C-H, respectively) dose during Fractionated Stereotactic Radiotherapy (FSRT) or Radiosurgery (SRS) for brain metastases (BM). Materials & methods Patients with BM   3 months, were considered for SRS/FSRT (total dose 15–30 Gy, 1–5 fractions). For each BM, a Flattening Filter Free (FFF) Volumetric Modulated Arc Therapy (VMAT) plan was generated with one or two arcs. Hippocampi were not considered during optimizations phase and were contoured and evaluated retrospectively in terms of dose: the Dmedian, Dmean, D0.1cc and the V1Gy, V2Gy, V5Gy and V10Gy were analyzed. Results From April 2…

Incidence rate of metastases in the oral cavity: a review of all metastatic lesions in the oral cavity

2021

Background Metastases in the oral cavity are rare and account for only 1 to 3% of all malignant lesions in this area. The primary location from which most metastases have been described in the oral cavity in adult patients include lungs, breasts, kidneys and colon. Material and Methods A systematic search of the literature was carried out following the PRISMA statement in PubMed database. Clinical trials and case series published in the last 10 years [2010-2020] were eligible to be selected. The headings and keywords used in the searches were “cancer” AND “oral metastases”, “incidence” AND “oral metastases”, “oral metastases” AND “jaw bone”, “oral metastases” AND “soft tissue”.

The prognostic value of sentinel lymph node micrometastases in patients with invasive breast carcinoma

2016

The prognostic value of sentinel lymph node micrometastases in invasive breast cancer patients is still widely debated. Even if, in the absence of unequivocal guidelines, the axillary lynphadenectomy is not still performed in the routine clinical care of these patients.We have retrospectively analyzed 746 patients with operable invasive breast cancer and clinically negative axillary lymph nodes. These patients underwent conservative surgery or total mastectomy with sentinel lymph node biopsy. Patients with micrometastases in the sentinel lymph node treated with axillary dissection has been checked and the involvement of the remaining lymph nodes analyzed. Patients with micrometastases in th…

Application of a predictive model of axillary lymph node status in patients with sentinel node metastasis from breast cancer. A retrospective cohort …

2016

Abstract Background and objectives The Axillary Lymph Node Dissection (ALND) is the standard treatment in patients with invasive breast cancer and sentinel node metastasis, but in 60% of the cases there is no further axillary neoplastic involvement, so this invasive intervention represents an overtreatment. The purpose of the study is to identify patients with low risk of additional nodal metastases, to omit ALND. Methods The MSKCC Additional nodal metastasis nomogram was applied on a sample of 175 patients with invasive breast cancer who underwent ALND after detection of macrometastasis with the extemporaneous examination of the sentinel lymph node. Patients were classified as "low risk" w…

Prognostic Effect of Epithelial Cell Adhesion Molecule Overexpression in Untreated Node-Negative Breast Cancer

2008

Abstract Purpose: Epithelial cell adhesion molecule (Ep-CAM) recently received increased attention not only as a prognostic factor in breast cancer but also as a potential target for immunotherapy. We examined Ep-CAM expression in 402 consecutive node-negative breast cancer patients with long-term follow-up not treated in the adjuvant setting. Experimental Design: Ep-CAM expression was evaluated by immunostaining. Its prognostic effect was estimated relative to overexpression/amplification of HER-2, histologic grade, tumor size, age, and hormone receptor expression. Results: Ep-CAM status was positive in 106 (26.4%) patients. In multivariate analysis, Ep-CAM status was associated with disea…

p95HER-2 Predicts Worse Outcome in Patients with HER-2-Positive Breast Cancer

2006

AbstractBackground: The HER-2 receptor undergoes a proteolytic cleavage generating an NH2-terminally truncated fragment, p95HER-2, that is membrane-associated and tyrosine-phosphorylated. We have reported that p95HER-2, but not the full-length receptor, p185HER-2, correlated with the extent of lymph node involvement in patients with breast cancer and its expression was significantly enhanced in nodal metastatic tissue. These facts suggested an important role for p95HER-2 either as a marker or cause of metastasis and poor outcome in breast cancer. In this work, we have studied the prognostic value of p95HER-2 in breast cancer.Methods: Primary breast tumor tissues (n = 483) were from surgical…

Validation of tumour-free distance as novel prognostic marker in early-stage cervical cancer: a retrospective, single-centre, cohort study

2021

Background: The aim of the present study was to assess the prognostic value of tumour-free distance (TFD), defined as the minimum distance of uninvolved stroma between the tumour and peri-cervical stromal ring, in early-stage cervical cancer. Methods: Patients with pathologic FIGO 2009 stage IA1–IIA2 cervical cancer, treated by primary radical surgical treatment between 01/2000 and 11/2019, were retrospectively included. Adjuvant treatment was administered according to the presence of previously established pathologic risk factors. TFD was measured histologically on the hysterectomy specimen. Pre-operative TFD measured at MRI-scan from a cohort of patients was reviewed and compared with pat…

Erratum: Phase II study of sequential hormonal therapy with anastrozole/exemestane in advanced and metastatic breast cancer

2005

Hormonal therapy is the preferred systemic treatment for recurrent or metastatic, post-menopausal hormone-receptor-positive breast cancer. Previous studies have shown that there is no cross-resistance between exemestane and reversible aromatase inhibitors. Exposure to hormonal therapy does not hamper later response to chemotherapy. Patients with locally advanced or metastatic, hormonal receptor positive or unknown, breast cancer were treated with oral anastrozole, until disease progression, followed by oral exemestane until new evidence of disease progression. The primary end point of the study was clinical benefit, defined as the sum of complete responses (CR), partial responses (PR) and >…

Deletion of Chromosome 11q Predicts Response to Anthracycline-Based Chemotherapy in Early Breast Cancer

2007

Abstract Despite the recent consensus on the eligibility of adjuvant systemic therapy in patients with lymph node–negative breast cancer (NNBC) based on clinicopathologic criteria, specific biological markers are needed to predict sensitivity to the different available therapeutic options. We examined the feasibility of developing a genomic predictor of chemotherapy response and recurrence risk in 185 patients with NNBC using assembled arrays containing 2,460 bacterial artificial chromosome clones for scanning the genome for DNA copy number changes. After surgery, 90 patients received anthracycline-based chemotherapy, whereas 95 did not. Tamoxifen was administered to patients with hormone r…

Epirubicin Plus Cyclophosphamide Followed by Docetaxel Versus Epirubicin Plus Docetaxel Followed by Capecitabine As Adjuvant Therapy for Node-Positiv…

2015

Purpose Capecitabine is an active drug in metastatic breast cancer (BC). GEICAM/2003-10 is an adjuvant trial to investigate the integration of capecitabine into a regimen of epirubicin and docetaxel for node-positive early BC. Patients and Methods Patients with operable node-positive BC (T1-3/N1-3) were eligible. After surgery, 1,384 patients were randomly assigned to receive epirubicin plus cyclophosphamide (EC; 90 and 600 mg/m2, respectively, × four cycles), followed by docetaxel (100 mg/m2 × four cycles; EC-T) or epirubicin plus docetaxel (ET; 90 and 75 mg/m2, respectively, × four cycles), followed by capecitabine (1,250 mg/m2 twice a day on days 1 to 14, × four cycles; ET-X); all regime…
