RESUMO

Breast cancer is the most common cancer amongst women worldwide. Recently, owing to screening programs and new technologies, the survival rate has increased significantly. Breast cancer can potentially develop metastases, and, despite them, lung metastases generally occur within five years of breast cancer diagnosis. In this study, the objective was to analyze the effect of breast cancer-derived EVs on a lung epithelial cell line. BEAS-2B cells were treated with extracellular vesicles (EVs) derived from triple-negative breast cancer cells (TNBCs), e.g., MDA-MB-231 and HS578T, separated using differential ultracentrifugation. We observed an increased growth, migration, and invasiveness of normal epithelial lung cells over time in the presence of TNBC EVs compared to the control. Therefore, these data suggest that EVs released by tumor cells contain biological molecules capable of influencing the pro-tumorigenic activity of normal cells. Exploring the role of EVs in oncology research and their potential cargo may be novel biomarkers for early cancer detection and further diagnosis.

RESUMO

Background: Breast localization plays a key role in early breast cancer (BC) surgery. The current gold standard is wire-guided localization (WGL), despite the known disadvantages. The patients often experience anxiety and discomfort due the metallic wire placed in the breast, and surgeons are compelled to perform the surgery on the same day as the radiological release of the wire to prevent migrations or breakages. Various wireless systems have been proposed as alternative to WGL. LOCalizerTM offers the advantage of providing the exact distance from the marker called Tag. The combined technique using LOCalizerTM and US allows for determining the distance from the BC margin, a critical surgical goal for oncological radicality. Methods: Patients referred for breast surgery to two Italian hospitals were enrolled and divided into two groups: Group A, including patients undergoing a combined approach, and group B, including patients treated with conventional WGL. Results: The combined approach with LOCalizerTM and US was associated with better outcomes in terms of oncological radicality, cosmetic results, and patients' satisfaction. Conclusions: In the current study, LOCalizerTM associated with US could be considered an excellent approach for localizing non-palpable BC. Further larger comparative studies are needed to address this issue.

RESUMO

INTRODUCTION: According to literature, primary Hodgkin's lymphomas of the breast represent one of the rarer entity in the primary breast lymphoma (PBL) scenario. This is the reason why these tumors are insidious in mammary oncology. PRESENTATION OF THE CASE: We report a case of HL primitive breast in an elderly patient in whom radiology suspected an advanced breast cancer with ipsilateral axillary involvement and in which the fine-needle aspiration came back not significant. DISCUSSION: Eighteen cases of primary Hodgkin's lymphoma of the breast has been described in Literature in a very large period of time: from 1928 to 2016. The nodular sclerosis type is the most frequent histological variant. CONCLUSION: Their rarity together with the fact that radiological investigations are not significant for the purpose of an exact diagnosis, make these lesions extremely difficult to identify.

RESUMO

BACKGROUND: Angiosarcoma is an aggressive vascular neoplasm with a high propensity for local recurrence. Electrochemotherapy is an emerging skin-directed therapy, exerting prominent cytotoxic activity, and antivascular effects. Its efficacy in angiosarcoma has not been investigated. METHODS: This multicenter retrospective analysis reviewed patients who underwent electrochemotherapy from 2007 to 2014 for superficial advanced angiosarcomas. Bleomycin was administered intravenously and delivered within tumors by means of percutaneously applied electric pulses, according to the European Standard Operating Procedures for Electrochemotherapy. Tumor assessment was performed using RECIST (version 1.1). Toxicity (CTCAE, v4.0) and local progression-free survival (LPFS) were also evaluated. RESULTS: Nineteen patients (13 with locally advanced and 6 with metastatic angiosarcomas) were treated. Tumor sites were: scalp (n = 5), breast (n = 8), other skin sites (n = 3), and soft tissue (n = 3). Target lesions (n = 54) ranged in size from 1.5 to 2.5 cm (median, 2 cm). Treatment was well tolerated. After 2 months, an objective response was observed in 12/19 (63%) patients, complete in 8 (42%). One-year LPFS within treatment field was 68%. Local symptom improvement included palliation of bleeding (5/19 patients) and pain relief (6/19 patients). CONCLUSIONS: Electrochemotherapy may represent a new locoregional treatment for selected patients with superficial angiosarcomas. J. Surg. Oncol. 2016;114:246-253. © 2016 Wiley Periodicals, Inc.

RESUMO

INTRODUCTION: Angiosarcomas are highly malignant endothelial cell tumors with poor prognosis. These can be due to breast cancer itself or to subsequent therapeutic modalities. No evidence-based guidelines exist concerning the ideal treatment of angiosarcomas. PRESENTATION OF THE CASE: We report the case of a 76-year-old woman who developed an exuberant and aggressive post radiation angiosarcoma of the breast and discuss different aspects of therapy for this disease. A total left mastectomy was performed, followed by a right mastectomy. The lesions into the chest wall, and multiple abdominal skin nodules were treated with local Electrochemotherapy (ECT) with intravenous bleomicin. DISCUSSION: No evidence-based guidelines exist concerning the ideal treatment of angiosarcomas. Electrochemotherapy (ECT) is an efficient palliative treatment of cutaneous and subcutaneous tumor nodules. It consists of the combination of a cytotoxic drug and electroporation, using appropriate electrical parameters; destabilization of the membrane is reversible, ensuring a high survival of permeabilized cells and the delivery of non-permeant molecules inside the cell. CONCLUSION: Due to the rarity of the disease, prospective studies concerning adjuvant or neoadjuvant therapy are limited and no evidence-based guidelines exist. The response to chemotherapy seems to be poor. Treatment with ECT in addition to systemic chemotherapy achieves a complete response in all the lesions and improving patient body image perception.

RESUMO

BACKGROUND: Breast cancer surgery with axillary lymphadenectomy may be associated with prolonged stay of the drain in the axilla due to high wound output, which may require further treatments and prolong the length of stay, impairing quality of life. No definitive data are available concerning how to prevent this complication. Our aim was to assess the efficacy of a new low-thrombin fibrin glue in reducing the serous output from the axillary surgical wound in patients undergoing axillary node dissection for breast cancer, and its long-term effects on lymphedema. METHODS: Sixty patients undergoing surgery between September 2012 and June 2013 were enrolled. Thirty patients received Artiss®(Baxter, UK) fibrin glue plus drainage, and 30 drainage alone. A multivariate analysis was performed to identify predictors of seroma, and subgroup analyses were performed. Lymphedema was assessed 12 months after surgery. RESULTS: Patients who received fibrin glue had reduced serum output collected in the drain after surgery (94.3 ± 22.4 vs 176 ± 24.6 ml p < 0.001) and shorter length of postoperative hospital stay (p = 0.001). Incidence of seroma at 4-week follow-up did not differ between groups. At multivariate analysis, BMI ≥ 30 kg/m(2) was the only independent predictor of seroma formation (OR = 2.7, 95%CI 1.4-5.3; p = 0.002). Overweight patients receiving Artiss® had fewer seroma at 4-week follow-up compared with control overweight patients (0% vs 55.6%, p = 0.03). No differences were observed in lymphedema between groups (6.7% vs 10%, p > 0.99). CONCLUSIONS: Low-thrombin fibrin glue reduced the amount of fluid produced in the axilla after breast surgery. Overweight patients may be the ideal candidates for this treatment. Such sealant did not increase the rates of lymphedema.

RESUMO

Surgical site events (SSE), including surgical wound complications and surgical site infections, are a major concern in patients undergoing general surgery operations. These increase the costs of care, and can lead to prolonged hospital stay and need for further treatments, ultimately resulting in poor quality of life. Negative pressure wound therapy (NPWT) has been recently reported as a preventive strategy to avoid SSE, but little is known on the topic, and particularly in geriatric population. Our primary aim was to assess the efficacy of NPWT by means of a pocket device (PICO, Smith & Nephew, London, UK) in preventing SSE compared with conventional dressings in patients undergoing surgery with primary wound closure for breast and for colorectal diseases in our Unit. Our secondary aims were to assess the efficacy and safety of PICO in elderly patients, and to seek for differences between breast and abdominal results. All consecutive patients undergoing breast and colorectal surgery in our Unit between September 2012 and May 2014 were prospectively enrolled in this open label controlled study. Breast patients receiving NPWT were assigned to group B1, those receiving conventional dressings were assigned to group B2. Colorectal patients were assigned to group C1 (NPWT) and C2 (conventional dressings) in similar fashion. Each group included 25 patients, and at least 10 (40%) patients aged over 65 years to allow sub-analyses. NPWT significantly reduced SSE in both breast and colorectal patients compared with controls. No significant differences were observed according to age. Similar benefits were observed in breast and colorectal patients. Our results suggest that PICO is an effective tool to prevent SSE in patients undergoing general surgery, irrespective of age. Its use is recommended in frail, elderly patients at risk of SSE.

RESUMO

BACKGROUND: Gallbladder adenomyomatosis (GBA) is a hyperplastic disease affecting the wall of the gallbladder, with some typical features. It has historically been considered a benign condition, nevertheless recent reports highlighted a potential role of GBA in predisposing to malignancies of the gallbladder. DATA SOURCES: We reviewed the literature concerning GBA from its identification until July 2012. Owing to the relative rarity of the disease, studies often are case reports or case series. Thus we herein report a summary of the key-points concerning diagnosis and treatment of GBA, easily applicable in everyday practice, rather than a systematic review. Also, results are integrated with our recent experience. RESULTS: In our experience, we observed a trend toward an increase of GBA during the last years, probably due to enhanced ultrasonographic technical advancements and physician's expertise. GBA has distinctive imaging features. Several recent reports highlight the potential risk of cancer associated with GBA; however the disease is still classified as a benign condition. Although its correlation with malignancy has not been demonstrated, it is prudent to recommend cholecystectomy in some cases. However, in selected asymptomatic patients, a wait-and-see policy is a viable alternative. We propose an algorithm, based on GBA pathological pattern (diffuse, segmental, localized or fundal), suitable for decision-making. CONCLUSIONS: In symptomatic patients and if the diagnosis is doubtful, cholecystectomy is mandatory. Postponing surgery is an option to be offered to asymptomatic patients with low-risk GBA pattern who adhere to scheduled follow-ups.

RESUMO

BACKGROUND: Open inguinal hernia repair is associated with a low incidence of complications that can be influenced by the type of mesh and its method of fixation. Our aim was to investigate the frequency and severity of postoperative pain and other complications when lightweight, large-pore meshes, compared with heavyweight, small-pore meshes, are fixed with human fibrin glue (HFG) during open inguinal hernia repair. METHODS: A cohort of 80 patients undergoing open inguinal repair were enrolled. Forty patients received a lightweight and large porous mesh and 40 a standard heavyweight mesh with small pores. In all patients, HFG was used for mesh fixation. RESULTS: Patients who received lightweight, large-pore mesh reported less pain than those in the control group both postoperatively (2.8 ± 1.1 vs. 4.9 ± 1.1; P = .0003) and at 1-month follow-up (1.7 ± 1.0 vs. 3.1 ± 1.0; P = .0038), and took fewer analgesics. There was no difference in days off work/activity. No differences were observed concerning postoperative complications. After 6 months there was no difference in groin pain between groups. CONCLUSION: Patients who underwent open inguinal hernia repair with lightweight, large-pore mesh fixed with HFG experienced less pain throughout the first month after operation compared with those receiving standard mesh.

RESUMO

BACKGROUND: The management of cutaneous metastases often represents a challenge because they may be widespread and may recur after radiotherapy or chemotherapy; breast cancer accounts for 51% of the total cases of cutaneous metastases. When surgical excision of chest wall recurrences is not possible and other local treatments such as radiotherapy or radiotherapy with hyperthermia fail, topical chemotherapy and electrochemotherapy (ECT) might be taken into account.ECT is a new local treatment of solid tumors which can be defined as the local potentiation, by means of permeabilizing electric pulses, of the antitumor activity of a non permeating anticancer drug with high intrinsic cytotoxicity. METHODS: This prospective observational study took place throughout March 2010 to October 2011. Twelve consecutive elderly patients (1 man and 11 women, median age of 76 years) with regional or distant skin or subcutaneous metastases from breast cancer, with or without visceral disease, were included in the study. Patient enrollment was carried out according to the ESOPE criteria. Bleomycin administration was followed by the application of brief electric pulses to each tumor nodule within 8 min after intravenous infusion of the drug. Electric currents were delivered by means of a 2-3 cm long needle electrode according to lesion size. All treatments were performed using the CliniporatorTM device. RESULTS: We observed Complete Response(CR) in 75.3% (107 metastases), Partial Response(PR) in 17% (24 metastases), no change in 7.7% (11 metastases) . No serious ECT-related adverse events were reported; adverse events consisted of pain in the treated area one to two days after treatment (1 patient, 8.3%) and ulceration of treated area (1 patient, 8.3%). CONCLUSION: ECT could be suggested as a primary local therapy in patients not suitable for surgical removal of the primary tumor, and clinicians should not hesitate to use it even in the elderly.

RESUMO

BACKGROUND: Where population coverage is limited, the exclusive use of Cancer Registries might limit ascertainment of incident cancer cases. We explored the potentials of Nationwide hospital discharge records (NHDRs) to capture incident breast cancer cases in Italy. METHODS: We analyzed NHDRs for mastectomies and quadrantectomies performed between 2001 and 2008. The average annual percentage change (AAPC) and related 95% Confidence Interval (CI) in the actual number of mastectomies and quadrantectomies performed during the study period were computed for the full sample and for subgroups defined by age, surgical procedure, macro-area and singular Region. Re-admissions of the same patients were separately presented. RESULTS: The overall number of mastectomies decreased, with an AAPC of -2.1% (-2.3 -1.8). This result was largely driven by the values observed for women in the 45 to 64 and 65 to 74 age subgroups (-3.0%, -3.4 -3.6 and -3.3%, -3.8 -2.8, respectively). We observed no significant reduction in mastectomies for women in the remaining age groups. Quadrantectomies showed an overall +4.7 AAPC (95%CI:4.5-4.9), with no substantial differences by age. Analyses by geographical area showed a remarkable decrease in mastectomies, with inter-regional discrepancies possibly depending upon variability in mammography screening coverage and adherence. Quadrantectomies significantly increased, with Southern Regions presenting the highest average rates. Data on repeat admissions within a year revealed a total number of 46,610 major breast surgeries between 2001 and 2008, with an overall +3.2% AAPC (95%CI:2.8-3.6). CONCLUSIONS: In Italy, NHDRs might represent a valuable supplemental data source to integrate Cancer Registries in cancer surveillance.

RESUMO

Breast cancer, a leading cause of cancer related deaths worldwide, is one of the most common neoplasms in women. The increased generation of reactive oxygen species (ROS) in breast lesion is critically involved in the mutagenic processes that drive to breast carcinoma initiation and progression. To date, the molecular events occurring in the tissue adjoin the cancer lesion have not been elucidated. Here, we investigated the role of excess ROS generation during human breast carcinogenesis by evaluating oxidative stress biomarkers, tissue transglutaminase (t-TGase) activity, and expression levels of ubiquitin and cyclooxygenase-2 (COX-2) in the normal tissue adjoin to fibroadenoma (nFA), atypical ductal hyperplasia (nADH), and invasive ductal carcinoma (nIDC) from 45 breast cancer patients. We found that lipid peroxidation and nitric oxide production significantly increased in nIDC respect to nFA and nADH (P < 0.005) whereas the 4-hydroxy-2-nonenal (HNE) protein-adducts increased only in nADH (P < 0.005). The increased lipid damage observed in nIDC correlates with estrogen receptor exposure in IDC (R(2) = 0.89). Moreover, nIDC and invasive ductal carcinoma (IDC) showed a 10-fold higher t-TGase activity compared to nFA and nADH. Contrary, COX-2 expression levels significantly decreased nIDC and IDC respect to the nFA and nADH (P < 0.001). The analysis of the free ubiquitin expression revealed equal levels in nADH and nIDC samples whereas high molecular weight-ubiquitin conjugate increased about fivefold only in nIDC (P < 0.01 vs. nADH). These novel findings reveal an interplay between membrane lipid peroxidation, t-TGase activity, and COX-2 expression levels in the tissue adjoining to neoplastic lesion during breast cancer progression.

RESUMO

BACKGROUND/AIMS: The total mesorectal excision (TME) for rectal tumours was introduced in 1982 by Heald et al. and has led both to a 5% de crease of local recurrences 5 and 10 years after the operation when compared with cases treated with conventional surgery, and to an increase of survival up to five years estimated in 80% of all cases. In Italy TME was firstly introduced for distal rectal carcinomas about 20 years ago, and has shown the same rate of local recurrences reported by Heald. The aim of our work is to highlight TME advantages and demonstrate how this more demanding and longer lasting method has an acceptable risk for the surgery of rectal tumours. METHODOLOGY: We have compared two groups of patients operated for rectal carcinoma; the first, "historical control group" (no TME, including 46 patients) was treated with the standard surgery technique, while the second group (TME, 47 patients) underwent the total mesorectal excision technique. 14 of non TME patients belonged to Dukes stage A, 20 to stage B and 12 to C; whereas in the TME group 16 patients belonged to Dukes stage A, 23 to B and 8 to C. The patients of both groups undergone the exams of follow up (blood test, hepatic ultrasonography, abdominal CT, thorax Ro); the follow up pattern included periodic controls with a check-up every three and six months, from one to five years. RESULTS: Postoperative complications in both groups do not show important differences in rates, although, the first group (no TME) had 11 cases with postoperative complications confronted with the 8 cases of the second group (TME). The complications taken into consideration were: anastomotic bleeding (3 patients no TME, 6% vs 1 patients TME, 2%), intestinal obstruction (1 patient no TME, 2% vs 1 patient TME, 2%), parietal infection (4 patients no TME, 9% vs 3 patients TME, 6%), anastomotic fistulae (2 patients no TME, 4% vs 2 patients TME, 4%), retention of urine and vesicular disorder (1 patient no TME, 2% vs 1 patient TME, 2%). Tumours closer to the anus have shown more complications compared with tumours at higher levels. As a matter of fact, 9 cases of no TME and TME patients with low located tumours have undergone complications compared with the 3 cases of no TME and TME patients with tumours being more distant from the anus; the rest 7 cases belonged to the middle rectum. A higher rate of local recurrences was noticed in the no TME group: 6 (13%) compared with the TME group: 3 (6%). Other tardy complications taken into consideration were: hepatic metastasis (5 patients no TME, 11% vs 4 patients TME, 8%), pulmonary metastasis (3, 6% of the no TME vs 2, 4% of the TME), anastomotic stenosis (4, 9% of the no TME vs 2, 4% of the TME), impotence (2, 4% of the no TME vs 1, 2% of the TME). We also noticed that most of the tardy complications in the TME group belonged to Dukes stage C. CONCLUSION: From our experience, we concluded that, in TME patients, complications are lower than in no TME patients; the site of the tumour affects the appearance of complications which are more frequently in distal localizations. An important result is the minor incidence of local recurrences after TME, which brings us to the conclusion that TME can be considered a valid method with an acceptable risk for the surgery of rectal tumour.

RESUMO

Adrenogenital Syndrome, more properly defined as Congenital Adrenal Hyperplasia (CAH), is related to the enzyme 21-beta-hydroxylase deficiency, with impaired glucocorticoids and aldosterone syntheses and increased ACTH synthesis. This report describes a case of a monorchid patient suffering from Adrenogenital Syndrome and Leydig cell tumor of his testis. A right orchidectomy with implantation of testis prosthesis was performed, after informing the patient on the consequences of his castration and obtaining his consent. Histology showed a testis measuring 4 x 3 x 2.5 cm with a 6 cm long spermatic cord; there was a yellowish, well-defined nodule measuring 3.5 x 1.5 cm, surrounded by normal parenchyma. This nodule had morphologic and immunohistochemical characteristics of a Leydig cell tumor, even found in the spermatic cord; those cells showed positivity to inibine, MART-1 and vimentine.

RESUMO

UNLABELLED: Breast surgery is classified among the procedures performed in clean surgery and is associated with a low incidence of wound infection (3-15%). The objective of this study was to evaluate the advantages antibiotic prophylaxis in patients undergoing breast surgery. A multicenter randomized controlled study was performed between January 2008 and November 2008. One thousand four hundred patients were enrolled in prospective randomized study; surgical wound infection was found in 41 patients (2.93%). In our RCT we have shown that in breast surgery antibiotic prophylaxis does not present significant advantages in patients with potential risk of infection (17 patients, 2.42%, subjected to antibiotic prophylaxis vs 24 patients, 3.43%, without antibiotic prophylaxis) (P = 0.27). In patients with drainage there is a significant minor incidence of wound infections in patients receiving antibiotic prophylaxis (5 patients, 0.92%, subjected to antibiotic prophylaxis vs 14 patients, 3.09%, without antibiotic prophylaxis) (P = 0.02). CONCLUSION: This study is only a preliminary RCT to be followed by a study which should be enrolled more patients in order to get the results as statistically significant.

OBJECTIVES: We aimed to determine the incidence of women's breast cancer in Italy without using statistical approximations. METHODS: We analyzed the national hospitalizations database at the Ministry of Health to calculate the number of major surgeries in Italian women (mastectomies and quadrantectomies) due to breast cancer between 2000 and 2005, overall and by age groups (<44, 45-64, 65-74 and >or= 75 years old). RESULTS: Over the six years examined, an overall number of 100,745 mastectomies and 168,147 quadrantectomies were performed. A total of 41,608 major surgeries due to breast cancer were performed in the year 2000 and this number rose to 47,200 in 2005, with a 13.4% increase over six years. CONCLUSION: by analyzing the hospitalizations database concerning major breast surgery, incidence of breast cancer in Italy was found to be 26.5% higher than the official estimations which have been computed using statistical models (namely 47,200 vs. 37,300 cases in year 2005).

RESUMO

Preoperative localisation of non-palpable breast lesions is necessary for excisional biopsies. This can be achieved with methods such as anchor wire, charcoal marking, or radio-guided localisation. The aim of the present study was to evaluate retrospectively our experience with the wire localisation technique. One hundred and eighty-two patients with non-palpable breast lesions (diameter: 0.4-1.5 cm) were operated on under local anaesthesia. Intraoperative X-rays were performed in all cases. No serious perioperative complications occurred. Three patients (2 with postoperative haematomas and 1 with wound infection) underwent conservative therapy. The lesions were benign in 67/182 patients (37%), ductal and/or lobular invasive cancer in 42 (23%), carcinoma in situ in 23 patients (12.5%) and ADH-ALH in 50 patients (27.5%). Our experience confirms that wire localisation biopsies constitute an excellent method for the excision of non-palpable breast lesions. This technique is characterised by high reliability (100% total excisions) and assures a prognostic evaluation of high-risk lesions such as ductal an/or lobular atypical hyperplasia.

RESUMO

At present the surgical treatment of lower limb varicose veins is performed mainly as day case surgery. Since 30% of elderly people suffer from this disease, the feasibility of phlebological operations in elderly patients in a day care setting is an emerging problem. All patients (2032 patients) who underwent varicose vein surgery in our Geriatric Surgery Department over a 10-year period from January 1993 to December 2002 were evaluated retrospectively; 312 patients (15.35%) were aged above sixty-five years. In this group of elderly patients, 214 (68.6%) were operated on as inpatients and 98 (31.4%) as day care cases; in the younger group, 60.23% were treated in a day care regimen. All patients were examined and selected depending on general conditions, local conditions and logistics. Among the general conditions the exclusion criteria for elderly patients were concomitant diseases (43.9%) and anxiety (17.8%); as a consequence of local conditions, 31 patients (14.5%) with extensive bilateral varices and 27 patients (12.6%) with complicated recurrent disease were excluded from day care surgery; 24 patients (11.2%) were excluded because of logistics. Almost half (44.9%) of the elderly patients required multiple admissions for diagnostic investigations. The elderly patients underwent fewer saphenous strippings (7.1% vs 15.9%) and below-knee strippings (48.0% vs 56.9%); on the other hand, there were more operations on perforating veins (7.1% vs 1.4%), more varicectomies 10.2% vs 1.7%) and more skin grafts for ulcers (8.2% vs 2.2%). No problems occurred during the interventions and none of the patients had to be re-admitted to hospital for complications. This study provides evidence that varicose veins can be safely managed in a day care unit even in elderly patients, though careful preoperative selection is necessary.
