Sentinel lymph node biopsy in breast cancer: ten-year results of a randomized controlled study.

Objective: Sentinel node biopsy (SNB) is widely used to stage the axilla in breast cancer. We present 10-year follow-up of our single-institute trial designed to compare outcomes in patients who received no axillary dissection if the sentinel node was negative, with patients who received complete axillary dissection.

Methods: From March 1998 to December 1999, 516 patients with primary breast cancer up to 2 cm in pathologic diameter were randomized either to SNB plus complete axillary dissection (AD arm) or to SNB with axillary dissection only if the sentinel node contained metastases (SN arm).

Clinicopathologic characteristics of invasive lobular carcinoma of the breast: results of an analysis of 530 cases from a single institution.

Background: Although invasive lobular carcinoma (ILC) is the second most common histotype of breast cancer, the prognostic implications of its clinicopathologic characteristics remain controversial.

Methods: The authors undertook a retrospective analysis of a large series of cases treated and followed at a single institution, with the objective of assessing the prognostic/predictive value of distinct clinicopathologic features of the tumors, after revision of the original histopathologic preparations and statistical analyses.

Results: Overall, 530 patients with pure ILC (57% with the classic type; 19% with the alveolar type; 11% with the solid type; and the remaining 13% characterized by pleomorphic, signet ring cell, histiocytoid, or apocrine features) were included in the study.

Preliminary results of electron intraoperative therapy boost and hypofractionated external beam radiotherapy after breast-conserving surgery in premenopausal women.

Purpose: To report the acute and preliminary data on late toxicity of a pilot study of boost with electron intraoperative therapy followed by hypofractionated external beam radiotherapy (HEBRT) of the whole breast.

Methods And Materials: Between June 2004 and March 2007, 211 women with a diagnosis of early-stage breast cancer were treated with breast-conserving surgery. During surgery, an electron intraoperative therapy boost of 12 Gy was administered to the tumor bed.

The surgical margin status after breast-conserving surgery: discussion of an open issue.

Hypothesis The best therapeutic approach to the involved or proximal surgical margins has not been defined yet; surgical margins status can influence the local relapse of disease in breast carcinoma, but the impact on overall survival has not been clearly demonstrated. Purpose of this work is to find in the available literature further evidence to guide the therapeutic behaviour in patients with close margins by invasive carcinoma. Design Review of the currently available literature on the evaluation of surgical margins in breast conserving surgery; influence of margin involvement by invasive component or intraductal component.

Paget's disease of the breast: the experience of the European Institute of Oncology and review of the literature.

Background: Paget's disease of the breast is an uncommon presentation of breast malignancy, accounting for 1-3% of all the breast tumors and presents in different histopathologic patterns: in association with an underlying invasive or non invasive carcinoma, or without any underlying neoplasia. In the literature, different methods are used for the treatment. Mastectomy with or without axillary dissection has been considered as the standard treatment procedure for many years.

Elements related to heterogeneity of antibody-dependent cell cytotoxicity in patients under trastuzumab therapy for primary operable breast cancer overexpressing Her2.

Preliminary results from a pilot trial on trastuzumab's mechanism of action against operable breast tumors overexpressing Her2 suggested a role for antibody-dependent cell cytotoxicity (ADCC). To examine factors affecting ADCC intensity and variability, we extended this study to the phenotypic and functional analysis of circulating mononuclear cells in 18 patients. ADCC was induced by trastuzumab therapy in 15 of 18 patients (83%).

When sentinel lymph node is intramammary.

Introduction: Sentinel lymph node biopsy is an accepted standard of care for staging the axilla in patients with early-stage breast cancer. Little attention has been placed to the presence of intramammary sentinel lymph nodes (intraMSLNs) on preoperative lymphoscintigraphy.

Methods: Between December 2001 and September 2006, in 9632 breast cancer patients with clinically uninvolved axillary nodes, lymphoscintigraphy was performed at the European Institute of Oncology (EIO).

The sentinel node biopsy under local anesthesia in breast cancer: advantages and problems, how the technique influenced the activity of a breast surgery department; update from the European Institute of Oncology with more than 1000 cases.

Sentinel lymph node biopsy (SLNB) is a staging technique with a significant impact on patients' quality of life: the oncological effectiveness in a large number of patients affected by breast carcinoma has been already demonstrated, and the clinical research is now focusing on new indication for the biopsy and widespread adoption of the technique. At the European Institute of Oncology we are applying SLNB under local anesthesia: our aim is to improve the management of the disease with low costs for the structure and patients, and to improve patients' acceptance of breast cancer treatments. We are now discussing the impact of the SLNB under local anesthesia on the activity of a breast surgery department.

Accuracy of computed tomography perfusion in assessing metastatic involvement of enlarged axillary lymph nodes in patients with breast cancer.

Introduction: The purpose of this study was to evaluate the diagnostic accuracy of computed tomography (CT) perfusion in differentiating metastatic from inflammatory enlarged axillary lymph nodes in patients with breast cancer.

Methods: Twenty-five patients with 26 locally advanced breast tumors and clinically palpable axillary lymph nodes underwent dynamic multi-detector CT (LightSpeed 16; General Electric Company) at one scan per second for 150 seconds at the same table position after 40 ml intravenous contrast injection at 4.0 ml/second.

Synchronous bilateral breast cancer in men: a case report and review of the literature.

Breast carcinoma is a rare disease in men, and bilateral cases are extremely uncommon. The rarity of male breast carcinoma and the small number of large studies on this topic have made it necessary to extrapolate treatment standards and outcomes from those established for women. Between 1997 and 2007, 75 men with breast cancer were referred to our institute, and the bilateral case we present here was the only one we have observed since 1994.

Sentinel lymph node biopsy in male patients with early breast cancer.

Mastectomy with axillary dissection is still the most commonly recommended procedure for male breast cancer. The aim of this study was to retrospectively evaluate our experience in 32 male patients with early breast cancer who underwent sentinel lymph node biopsy (SLNB) and axillary dissection only in cases of metastases in the sentinel lymph node (SLN). The median age was 58 years (range, 33-80).

Male breast cancer in a young patient treated with nipple-sparing mastectomy: case report and review of the literature.

Male breast carcinoma is an uncommon phenomenon, accounting for less than 1% of all malignancies of the breast. The approximate annual incidence in Europe is 1 in 100,000 cases. The highest incidence occurs 5-10 years later in men than in women, with a peak at 60 to 67 years of age.

The evolution of the conservative approach to breast cancer.

The profound revolution that surgical treatment of breast cancer has undergone during the past 30 years has led to the progressive reduction of the extent of surgery, with less mutilation. As a consequence, quality of life has improved and women are now more motivated to follow screening programs for early diagnosis of the disease. Since conservative surgery is as effective as radical surgery, research is now focused on reducing radiotherapy.

Sentinel-lymph-node biopsy as a staging procedure in breast cancer: update of a randomised controlled study.

Background: In women with breast cancer, sentinel-lymph-node biopsy (SLNB) provides information that allows surgeons to avoid axillary-lymph-node dissection (ALND) if the SLN does not have metastasis, and has a favourable effect on quality of life. Results of our previous trial showed that SLNB accurately screens the ALN for metastasis in breast cancers of diameter 2 mm or less. We aimed to update this trial with results from longer follow-up.

Angiosarcoma of the breast: the experience of the European Institute of Oncology and a review of the literature.

Angiosarcoma of the breast (AB) is a rare entity: its overall incidence is estimated at between 0.002% and 0.005% per year.

Metaplastic carcinoma of the breast, an unusual disease with worse prognosis: the experience of the European Institute of Oncology and review of the literature.

Background: Metaplastic carcinoma of the breast is a rare form of breast cancer and has an uncertain prognostic significance. The purpose of the present study was to compare the clinical course, and prognosis, between this type of tumor and poorly differentiated ductal carcinoma.

Patients And Methods: We analyzed 37 cases of metaplastic carcinoma of the breast treated at our institution (European Institute of Oncology in Milan, Italy) between 1997 and 2004, comparing them with 72 cases (control group) of poorly differentiated ductal carcinoma.

Report on a case of pure cribriform carcinoma of the breast with internal mammary node metastasis: description of the case and review of the literature.

Aims And Background: Pure ductal invasive carcinoma of the breast is more frequently associated with lymphatic invasion, lymph node involvement and high malignant histological grade than combined forms of breast carcinoma. Internal mammary node metastases are not frequently detected when the axillary nodes are negative.

Patients And Methods: We report our experience of a case of pure cribriform carcinoma, associated with an intraductal cribriform component, in which the sentinel axillary nodes were negative, while nodal and perinodal metastasis was detected in one internal mammary lymph node.

Report on a case of breast sarcoma metastatic to the axillary lymph nodes.

Breast sarcoma is a rare entity that accounts for less than 1% of all breast malignancies; it may spread by direct invasion and/or through the blood. Axillary lymph node involvement is extremely rare and usually associated with advanced-stage disease. In the surgical treatment of this neoplasm, complete axillary lymphadenectomy is important for the local clearance of the clinically involved lymph nodes.

Nipple-sparing mastectomy in association with intra operative radiotherapy (ELIOT): A new type of mastectomy for breast cancer treatment.

Background: Breast-conserving surgery has become the standard approach for about 80% of patients treated for primary breast cancer in most centres. However, mastectomy is still required in case of multicentric and/or large tumours or where recurrences occur after conservative treatment. When a total mastectomy is performed, the removal of the nipple areola complex (NAC) is a strongly debated issue.

Conservative treatment of breast cancer: its evolution.

Background: Over recent decades, breast carcinoma surgery has witnessed a considerable evolution. The extent of surgery undertaken has progressively reduced, leading to less disfigurement and a significant improvement in quality of life, thereby offering women considerable motivation to seek early diagnosis. From an oncological perspective, outcome was found to be equally effective, and this key observation provided us with significant impetus to investigate the effects of reducing the radiotherapy field.

Full-dose intraoperative radiotherapy with electrons in breast surgery: broadening the indications.

Hypothesis: Although postoperative fractionated radiotherapy (PFR) remains the standard method for conservative treatment of breast carcinomas, widespread experience in the use of full-dose intraoperative radiotherapy with electrons (ELIOT) merits its application in novel clinical situations, although long-term results of ongoing clinical trials have not been fully reported.

Design: Retrospective case series.

Setting: Division of breast surgery in a comprehensive cancer center.
