Purpose: The present study aimed to define the antitumor activity of eight cisplatin – epirubicin – paclitaxel (PET) weekly cycles with granulocyte colony-stimulating factor (G-CSF) support in patients with large operable breast cancer. Methods: Operable breast cancer (T2 –3 N0– 1; T >3 cm) patients received eight preoperative weekly cycles of cisplatin 30 mg/m 2 , epirubicin 50 mg/m 2 and paclitaxel 120 mg/m 2 , with G-CSF (5mg/kg, days 3– 5) support. Results: Sixty-three patients (T2/T3 = 30/33; N0/N + = 8/55) were enrolled. Thirty-one clinical complete (49%) and 30 partial (48%) responses were recorded, giving a 97% response rate (95% confidence interval 89% to 100%). Breast-sparing surgery was performed in 32/63 (51%) patients. At pathological assessment, 28 patients (45%) showed absence of invasive residual disease in breast and 34 (55%) had negative axilla. In 20 women (32%) both breast and axilla were found to be disease-free. At a 23-month median follow-up (range 4 – 63), only eight relapses and two deaths had occurred, with the 4-year projected relapse-free and overall survival being 59% and 95%, respectively. Grade 3 – 4 neutropenia and anemia occurred in 24% and 5% of patients, respectively. Emesis, diarrhea and mucositis were the main non-hematological toxicities; however, only nine (14%) patients experienced one or more episodes of severe non-hematological toxicity. Peripheral neuropathy was frequent, but never severe. Conclusions: A 2-month weekly treatment with PET represents a well tolerated and highly effective approach in large operable breast cancer patients. In spite of the short duration of chemotherapy, one-third of patients achieved a complete eradication of the tumor in both breast and axilla.

Objectives: To study the clinical characteristics, treatment modalities, and outcome of patients with superior sulcus tumors who underwent surgery over a 15-year period. Design: Retrospective clinical study. Methods: Clinical records of all patients operated on for superior sulcus tumors by the same surgical team between 1988 and 2002 were reviewed retrospectively. Results: Sixty-seven patients were operated on in this period. All the patients underwent en bloc lung and chest wall resection. Surgical approaches were as follows: posterolateral thoracotomy according to Paulson (n = 33), combined transcervical and transthoracic approach (n = 33), and isolated transcervical approach (n = 1). Types of pulmonary resection included lobectomies (n = 59), pneumonectomies (n = 2), and wedge resections (n = 6). Pathologic stages were IIB, IIIA, and IIIB in 49 cases, 12 cases, and 6 cases, respectively. Resection was complete in 55 patients (82%). Operative mortality was 8.9% (n = 6). Postoperative treatment was administered in 53 patients (radiotherapy, n=42; chemoradiotherapy, n=9; and chemotherapy, n=2). Overall 2-year and 5-year survival rates were 54.2% and 36.2%, respectively. Five-year survival was significantly higher after complete resection than after incomplete resection (44.9% vs 0%, p=0.000065). The presence of associated major illness negatively affected the outcome (5-year survival, 16.9% vs 52%; p=0.043). Age, weight loss, respiratory impairment, tumor size, presence of nodal disease, and histologic type did not influence the long-term outcome. At multivariate analysis, only the completeness of resection and the absence of associated major comorbidities had an independent positive prognostic value. Conclusions: Superior sulcus tumor remains an extremely severe condition, but long-term survivals may be achieved in a large percentage of cases. The presence of associated major illness and the completeness of resection are the two most important factors affecting the long-term outcome.

Background The management of breast cancer (BC) skin metastases represents a therapeutic challenge. Electrochemotherapy (ECT) combines the administration of bleomycin with temporary permeabilization induced by locally administered electric pulses. Preliminary experience with ECT in BC patients is encouraging. Methods A total of 125 patients with BC skin metastases who underwent ECT between 2010 and 2013 were enrolled onto a multicenter retrospective cohort study. The treatment was administered following the European Standard Operative Procedures of Electrochemotherapy. Tumor response was clinically assessed adapting the Response Evaluation Criteria in Solid Tumors, and toxicity was evaluated according to Common Terminology Criteria for Adverse Events 4.0. Cox regression analysis was used to identify predictive factors. Results Response was evaluable in 113 patients for 214 tumors (median 1 per patient, range 1–3). The overall response rate after 2 months was 90.2 %, while the complete response (CR) rate was 58.4 %. In multivariate analysis, small tumor size (P

We report that a subset of circulating cells reacting with a monoclonal antibody raised against a protein marker is significantly increased in the peripheral blood of women carrying benign or malignant breast diseases, particularly in patients under 55 years of age with ductal mammary carcinomas. These cells were statistically (confidence level of 99%) less represented in a control population including healthy women or women carrying carcinomas of origin other than breast. Double staining analysis showed that they harbor markers of dendritic cells and exhibit endo- cytic activity, as determined by their ability to internalize FITC-dextran particles. Their dendritic morphology was further demonstrated by electron microscopy of sorted antibody-positive cells. However, expression of surface molecules, such as CD34 and CD14, usually not present in differentiated populations of dendritic cells was also observed. Adherent cells of patients with breast ductal carcinoma including mostly cells of this new subset were efficient stimulators of mixed lymphocyte reaction, attaining maximal stimulatory activity attained after TNFalpha treatment. In conclusion, we have shown that a subset of cells characterized by a phenotype suggestive of a yet undescribed stage of maturation of the dendritic cell lineage is accumulated in the blood of patients affected by breast proliferative disorders.

Pericardial effusions often complicate the course of endstage malignant conditions. 1 When frequent pericardio centheses are required, a pericardial window is indicated to permanently relieve tamponade symptoms. In patients with acceptable performance status, such a procedure has been performed either through an open or a video-assisted thoracoscopic surgery (VATS) approach with excellent results. 1
