RESUMO

Breast cancer treatment has deeply changed in the last decades, since clinical and oncological cure cannot be achieved without patient's satisfaction in term of aesthetic outcomes. Several methods have been proposed to objectively assess these results. However, Italian breast centers have not yet agreed on measurable, reproducible and validated aesthetic outcome indicators to monitor their performance. METHODS: The study was designed and conducted by Senonetwork, a not-for-profit association of Italian breast centers. Ten breast centers were selected based on specific eligibility criteria. This multicentre observational prospective study recruited 6515 patients with diagnosis of in situ or invasive breast cancer who underwent breast surgery in the years 2013-2016. Thirteen indicators of aesthetic results and of related quality of care were analyzed. Data collection and analysis were conducted using a common study database. RESULTS: On average, seven out of ten centers were able to collect data on the proposed indicators with a proportion of missing values < 25%. By expert consensus based on study results, some seven indicators have been defined as "mandatory" while the remaining six have been defined as "recommended" because they require further refinement before they can be proposed for monitoring aesthetic outcomes or because there are doubts on the feasibility of data collection. The minimum standard is reached for 5 of 13 indicators. This finding and the wide range between centers reveal that there is ample room for improvement. CONCLUSIONS: From the present study useful measurable aesthetic parameters have emerged, leading to the definition of target objectives that breast centers can use for benchmarking and improvement of quality of care.

RESUMO

BACKGROUND: Breast angiosarcoma is a malignant mesenchymal neoplasm, which accounts for approximately 2% of all soft tissue sarcomas. Secondary breast angiosarcoma (SBA) may be related to chronic lymphedema after a mastectomy with lymph node dissection (Stewart Treves syndrome) and previous radiotherapy for complications from breast radiation treatment. It is a very rare condition; therefore, diagnosis and management are still a challenge. METHODS: The ANISC collected SBA data by means of a survey sent to all Italian breast centres in the ANISC. The clinicopathological characteristics and the management of this disease were analysed. RESULTS: Twenty-four centres participated in this survey in which 112 cases of SBA were analysed. The median age of the women with SBA was 68.9 years and it appeared approximately 90 months after the first irradiation for breast cancer. In 92% of cases, a mastectomy was performed without axillary dissection for those patients having a high grade of SBA (74.2%). The prognosis was worse in the high-grade cases (overall survival-OS: 36 months) as compared with the low-grade cases (OS: 48 months). After a follow-up of 5 years, 50.5% of the patients were still alive. Disease-free survival (DFS) was 35 months, and there were no differences between the groups of patients with either high- or low-grade histology. CONCLUSIONS: Secondary breast angiosarcoma is a very aggressive disease associated with a short survival outcome. The surgical approach still remains an important step in the course of treatment; furthermore, an accurate histological examination is helpful in establishing the prognosis of the patient. A mastectomy is mandatory. A longer OS was observed in patients with low-grade angiosarcoma as compared to high-grade angiosarcoma (C.I. 40-57 vs. 31-41 months).

RESUMO

The Italian Society of Surgical Oncology (SICO) Breast Oncoteam developed a survey to explore the state of the art of neoadjuvant treatment for breast cancer in Italy, specifically focusing on cases treated during the two-year period 2014-2015. A questionnaire was sent to Italian Breast Units with a minimum of 150 new breast cancer cases treated/year according to the Senonetwork directory and to the SICO Breast Oncoteam Breast Unit network. A total of 23/107 Breast Units submitted the survey, reporting a total amount of 20156 cases of breast carcinoma (17241 invasive, 2915 in situ) treated in the biennium, corresponding approximately to 20% of newly diagnosed breast cancers in Italy. In the United States, medical treatment before surgery for breast cancer is indicated in about 22.7% of newly diagnosed cases according to the National Cancer Database, while a German study reported approximately 20% of cases treated with neoadjuvant therapy. In our survey, a total of 1673/17241 cases (9.7%) were treated with neoadjuvant therapy, ranging from 2.9% to 23.6% according to different centres, showing heterogeneity in neoadjuvant treatment indications, even in multidisciplinary breast units. Better resources should be engaged to achieve a standardised quality indicator for neoadjuvant treatment, and this indicator could be included among the European Society of Breast Cancer Specialists (EUSOMA) quality indicators. In the near future, we plan to develop a second survey to better test improvements in the employment of neoadjuvant therapy after the expiry of the 2016 European Parliament deadline and after the 2017 St. Gallen Conference recommendations.

RESUMO

OBJECTIVES: Breast-conserving therapy (BCT), including postoperative whole breast irradiation (WBI), is generally accepted as the treatment of choice for most patients with early-stage breast cancer. The question whether WBI is mandatory in all patients remains one of the most controversial issues in BCT. To answer this question, a randomized, prospective, multicentre study was launched in January 2001. Primary endpoints of the study were to assess the cumulative incidence of in-breast-recurrences (IBR) and overall survival (OAS) after conservative surgery (BCS) with or without WBI. METHODS: From January 2001 until December 2005, 749 patients with unifocal infiltrating breast cancer up to 25 mm, 0-3 positive axillary lymph nodes, no extensive intraductal component or lymphvascular invasion from 11 centres in Italy, were randomly assigned to BCS+WBI (arm 1:373 patients) or BCS alone (arm 2:376 patients). Treatment arms were well balanced in terms of baseline characteristics. Systemic adjuvant therapy was administered according to the institutional policies. Kaplan-Meier method was used for survival analysis and log-rank test to evaluate the difference between the two arms. RESULTS (Last analysis 31.12.2012): After median follow-up of 108 months, 12 (3.4%) IBR were observed in arm 1 and 16 (4.4%) in arm 2. OAS was 81.4% in arm 1 and 83.7% in arm 2. There was no statistically significant difference regarding IBR and death in the two treatment groups. CONCLUSIONS: These data are promising and suggest that WBI after BCS can be omitted in selected patients with early stage breast cancer without exposing them to an increased risk of local recurrence and death. Longer follow-up is needed to further consolidate these results.

RESUMO

Vascular endothelial growth factor (VEGF) is one of the most important inducers of angiogenesis, therefore blocking angiogenesis has led to great promise in the treatment of various cancers and inflammatory diseases. VEGF, expressed in response to soluble mediators such as cytokines and growth factors, is important in the physiological development of blood vessels as well as development of vessels in tumors. In cancer patients VEGF levels are increased, and the expression of VEGF is associated with poor prognosis in diseases. VEGF is a mediator of angiogenesis and inflammation which are closely integrated processes in a number of physiological and pathological conditions including obesity, psoriasis, autoimmune diseases and tumor. Mast cells can be activated by anti-IgE to release potent mediators of inflammation and can also respond to bacterial or viral antigens, cytokines, growth factors and hormones, leading to differential release of distinct mediators without degranulation. Substance P strongly induces VEGF in mast cells, and IL-33 contributes to the stimulation and release of VEGF in human mast cells in a dose-dependent manner and acts synergistically in combination with Substance P. Here we report a strong link between VEGF and mast cells and we depict their role in inflammation and immunity.

RESUMO

Cancer cells invade surrounding tissues and metastasize to distant sites. Diet high in fat is a strong link to, and perhaps causes, a high incidence of tumours. Trans-fatty acid might impair the function and it could be involved in the development of cancer. Cholesterol is also strongly suspected to be involved in the development of tumours, therefore it is important for everyone to eat well, especially for people with cancer to prevent the body tissues from breaking down and helping to rebuild the normal tissue that may have been affected by the treatments. Factors secreted by adipocytes and macrophages such as TNF-alpha and other inflammatory proteins are involved in inflammation in cancer. In addition, MCSF which up-regulates adipocyte tissue is also important for the stimulation of fat cell proliferation and is expressed by human adipocytes. Many cytokines, such as IL-1, IL-6, IL-8, IL-32, IL-33 and MCP-1, are biomarkers for cancer and chronic diseases along with transcription factors NFκB and AP-1; these last two factors are important bioactive substances on the molecular mechanism of the control of genes which in turn affect cellular metabolism. In this paper we revisit the interrelationship between cancer and metabolism.

RESUMO

Mast cells are granulated hematopoietic cells derived from stem cells that reside in nearly all tissues and are involved in protection of a host from bacterial infection with a protective and pathogenic activity. Mast cells are important for both innate and adaptive immunity in tissues which are in close contact with the environment. These cells express proinflammatory cytokines such as IL-1, IL-6, IL-8 and tumor necrosis factor which are necessary for innate immunity. Mast cells also produce interleukin-9 and enhance mast cell expression of several cytokines including IL-1beta, IL-5, IL-6, IL-9 and IL-13. In addition, IL-9 can induce mast cell production of TGF-beta which can have proinflammatory downstream effects. IL-9 can function as either a positive or a negative regulator of immune responses and can have a detrimental role in allergy and autoimmunity. Furthermore, IL-9 contributes to disease by promoting mast cell expansion and production of IL-13 which in turn contributes to airway hyperresponsiveness. Here, in this editorial we review the interrelationship between IL-9 and mast cells.

RESUMO

It has been reported that high levels of cholesterol and triglycerides are associated with increased risk of developing atherosclerosis and shorter life. In fact, vascular endothelial dysfunction occurs during the human aging process. Accumulation of lipids in vascular endothelium activates leukocytes to produce cytokines and chemokines which recruit macrophages. On the other hand, macrophages augment inflammatory response and secrete vascular endothelial growth factor, a key cytokine that mediates angiogenesis and inflammatory response. In addition, hyperlipidaemia is one of the main risk factors for aging, hypertension and diabetes. Here, we review the interrelationship between endothelial cells, high level of cholesterol, and aging.

RESUMO

The mechanism and formation of cancer have always been topics of interest for scientists, even for doctors in ancient times. Nowadays a great role for cancer is played by psychological stress which promotes relevant changes in neuronal activity and gene regulations across the different brain areas. It has been reported by many authors that stress can have an important role in the immune system and may be relevant in the formation of cancer. Our observations, in accordance with other research studies, confirm the importance of the influence of depression, linked to neuroendocrine stress, on the enhancement of cancer pathogenesis by inhibiting anti-tumor immune responses. In this article we review the past and present history of the relationship between cancer and psychology.

RESUMO

Atherosclerosis is an inflammatory disease due to a diet high in saturated fat, hypercholesterolemia, obesity, hypoglycemia, etc. mainly mediated by the infiltration of macrophage and T cells into the vascular wall. Once the endothelial is damaged monocytes penetrate the tissue and are transformed in scavenger cells. Upon stimulation of Th1 cells, a group of cytokines is released and contributes to the inflammatory response of atherosclerotic tissue. When macrophages proliferate they amplify inflammatory response through the secretion of growth factors and cytokines such as TNF and IL-1. In addition, chemokines such as RANTES and other C-C chemokines are generated, and matrix metalloprotinease 9 (MMP-9) are produced by activated monocytes. However, the immune system in atherosclerosis still remains unclear. Here, in this study we revisited the inter-relationship between atherosclerosis and inflammation.

RESUMO

Breast conserving therapy (BCT) including postoperative irradiation of the remaining breast tissue is generally accepted as the best treatment for the majority of patients with early-stage breast cancer. The question is whether there is a necessity for irradiating all patients. Between 2001 and 2005, 749 women aged 55-75 years with infiltrating breast carcinoma were randomly assigned to breast conservative surgery, with or without radiotherapy (RT), to evaluate the incidence of in-breast recurrence (IBR). After 5 years of median follow-up, the cumulative incidence of IBR was 2.5% in the surgery-only arm and 0.7% in the surgery plus RT arm. There are no differences in terms of overall survival and distant disease-free survival. The preliminary evaluation suggests that breast irradiation after conservative surgery can be avoided without exposing these patients to an increased risk of distant-disease recurrence. Prolonged follow-up will further clarify the possible risks and late sequelae potentially induced by breast RT.

RESUMO

BACKGROUND: This phase II study was conducted to evaluate tumor response rate and safety profile of dose-dense epirubicin plus cyclophosphamide followed by docetaxel plus capecitabine given preoperatively to patients with stage II or IIIA breast cancer. PATIENTS AND METHODS: Patients underwent four cycles of dose-dense cyclophosphamide 600 mg/m(2) and epirubicin 90 mg/m(2) every 2 weeks followed by two cycles of docetaxel 36 mg/m(2) on days 1, 8, and 15 plus capecitabine 1250 mg/m(2) on days 5-18 every 4 weeks, with prophylactic pegfilgrastim. The primary objective of the study was to determine the incidence of pathologic complete response defined as the absence of invasive or in situ cancer in the breast and the axillary nodes at definitive surgery. RESULTS: Forty-four patients were enrolled in the study and 41 (93%) were assessable for response to chemotherapy. An objective clinical response was observed in 38 (93%) patients. Seven patients (17.1%) exhibited a pathologic complete response. Breast-conserving surgery was carried out in 36 (88%) patients. Grade 3/4 neutropenia occurred in 4.3% of 252 administered chemotherapy cycles. No febrile neutropenia, cardiac toxicity, thrombocytopenia or other serious adverse event was registered. CONCLUSION: The sequential combination of dose-dense epirubicin plus cyclophosphamide followed by docetaxel plus capecitabine is an effective and well-tolerated neo-adjuvant chemotherapy for stage II, IIIA breast cancer.

RESUMO

We report on the screening of the entire BRCA1/BRCA2 coding sequence by SSCP, PTT, and direct sequencing in 68 Italian families with recurrent breast or ovarian cancer. For each investigated proband, the probability of being carrier of a BRCA1/BRCA2 mutation was evaluated using the BRCAPRO software. We detected BRCA1/BRCA2 mutations in 8 patients (11.7%). However, if considering only patients with a carrier probability >10%, the detection rate was 36.8%, confirming the usefulness of the BRCAPRO software. One change (BRCA1 4172insT) was a novel mutation not reported in BIC database.

RESUMO

The PJ, introduced by Rosen in the 1980, is a benign and localized mammary lesion in female under 30 years old. The most important clinical and histological features are: Diagnosis in juvenile age. A mass clinically localized. A nodule with histologic features of cyst, benign hyperplasia of ductal epithelium and galactophorus ducts dilatation (Swiss cheese disease). There is a correlation between patients with PJ and breast cancer there is an increment of breast cancer in familirs of patients with PJ. There is an increment of the risk to develop a K in situ in patients with PJ and apocrine metaplasia and/or adenomatosis and/or atypical mastoplasia. We describe the diffuse PJ in a girl of 23 years old from the 1996 to 2002.

RESUMO

BACKGROUND: The chronomodulated infusion of 5-FU, FA and oxaliplatin allows a significant increase in dose intensity and antitumor efficacy in patients with metastatic colorectal cancer. Here we investigated if substitution of oxaliplatin with cisplatin produced a similar antitumor activity in previously untreated patients with advanced colorectal cancer. METHODS: We enrolled 21 consecutively evaluated ambulatory patients with metastatic colorectal cancer. Each treatment cycle consisted of a 5-day course of continuous chronomodulated venous infusion of drugs. Daily doses were 600 mg/m2 5-FU, 150 mg/m2 FA (L-form), and 12 mg/m2 cisplatin. The cycles were repeated every 21 days. RESULTS: All patients completed at least 3 cycles. Overall a total number of 105 cycles were administered. One partial response (lasting 3 months) and 13 stable disease (lasting from 3 to 12 months) were observed. The remaining 7 patients had progression of the disease. Hematologic and gastrointestinal toxicity was always < or = G2 in all cycles. CONCLUSIONS: The results of this study discourage the substitution of cisplatin for the more active compound, oxaliplatin, in a chronomodulated schedule of infusion with 5-FU and FA in patients with metastatic colorectal cancer.

RESUMO

Galectin-3, a member of the beta-galactoside-binding animal lectins, has been implicated in tumor invasion and metastasis. Using an immunoligand assay, we assessed the circulating levels of galectin-3 in sera from cancer patients as well as from healthy controls. Low serum levels of galectin-3 were detected in healthy individuals (median, 62 ng/ml; range, 20-313 ng/ml; 95th percentile, 184.3 ng/ml). Compared with healthy individuals, galectin-3 serum levels in patients with breast, gastrointestinal, lung, or ovarian cancer, melanoma, and non-Hodgkin's lymphoma were significantly elevated (P = 0.014). Moreover, galectin-3 concentrations in sera from patients with metastatic disease were higher than in sera from patients with localized tumors. Maximum serum concentrations of galectin-3 (median, 320 ng/ml; range, 20-950 ng/ml) were found in patients with metastatic gastrointestinal carcinoma. These results suggest that circulating galectin-3 may play a role in tumor progression. The possibility of using this assay in early-stage cancer to predict metastasis should be studied.

RESUMO

Gynaecomastia is a benign enlargement of the male breast commonly occurring in healthy adolescent boys and in adults (50 to 80 years old). It is a source of cosmetic and psychologic problems. The secondary forms usually require no therapy other than the removal of any identified inciting cause. Most of the idiopathic forms last only a few months and then gradually disappear. In secondary gynaecomastia and idiopathic forms present for more than 12 months a medical hormonal treatment often fails and the only therapy is surgery consisting in a subtotal subcutaneous mastectomy. In the last years the surgical treatment is often completed with suction lipectomy: this procedure reduces the surgical traumatism. The authors present their experience concerning 47 patients: 27 were surgical treated with subcutaneous subtotal mastectomy and 18 had an abjunctive liposuction treatment with good results.

RESUMO

The authors present 20 cases of bilateral breast cancer (2 synchronous) on 700 cases of breast cancer observed in 1974-1992 period. In most cases (17 on 20) the histologic type was the same for both tumours and in 15 cases was invasive ductal. The time interval to second diagnosis went from 24 to 144 months with a mean interval of 44 months. The limited number of cases observed by the Authors doesn't permit conclusions about the prognostic meaning of a second breast cancer but it is clear that the anamnestic evidence of a previous intervention for breast cancer requires careful control also of the contralateral breast.

RESUMO

The authors examine the influence of ionogenic radiations on the onset of breast cancer. They remark the connection between the doses of radiations and the incidence of cancer and point out that the danger increases when the women is exposed to radiations during her fertile age.
