Objective: The relationship between loco-regional (LR) control and breast cancer survival was investigated with the intention of generating a new biological hypothesis to explain some of the paradoxes unaccounted for by the prevailing conceptual model of the disease. Background: The progressive reduction of surgical aggressiveness has been accompanied by an increase of breast cancer survival mainly attributed to the adoption of adjuvant systemic therapies. More recently, it has been recognized that effective LR control may prolong the survival of breast cancer patients, although the reasons for this improvement have not yet been clearly defined. Methods: The literature (PubMed) was reviewed for publications related to breast cancer LR treatments using the following key words: breast cancer surgery, breast cancer radiotherapy, breast cancer loco-regional control, breast cancer survival. Results: Although breast cancer is frequently a multifocal disease, neither mastectomy nor whole breast irradiation are always mandatory to obtain adequate local control. Conversely, selected groups of patients carry a particularly elevated risk of LR relapse and require more effective treatments to be developed. True LR recurrences are associated with a decreased overall survival and this may be related to a complex relationship between circulating tumor cells, re-seeding of the primary tumor site and several metabolic effects linked to the act of surgery. Conclusion: The prevention of LR recurrences is a major goal of breast cancer care, which requires a better understanding of the complex relationships between the primary tumor and its metastatic process. © 2012 Elsevier Ltd.

Purpose: To evaluate the incidence of residual disease after additional surgery for positive/close margins and the impact on the rate of local and distant recurrence. Methods: A retrospective analysis on 1339 patients treated for breast cancer with breast conserving-surgery and radiotherapy at a single Institution between 2000 and 2009 was performed. Results: During primary surgery 526 patients (39.3%) underwent intraoperative re-excision. At the final pathological report, the margins were positive in 132 patients (9.9%) and close in 85 (6.3%). To obtain clear margins, 142 of these women underwent a second surgery; 35 patients with positive margins (27%) and 40 with close margins (47%) did not receive additional surgery because of different reasons (patients refusal, old age, comorbidity or for focal margin involvement). At second surgery, residual disease was found in 62.9% of patients with positive margins and in 55.5% of those with close margins. At a median follow-up time of 4 years, local recurrence (LR) rate was 2.9% for patients with clear margins, 5.2% (. p=0.67) for patients with unresected close margins and 11.7% (. p=0.003) for those with unresected positive margins. The HER-2 and the basal-like subtypes had the higher rate of LR and the luminal A the lowest. Conclusions: A significantly higher LR rate was found only among patients with positive margins not receiving additional surgery, but not in those with unresected close margins. Positive margins are a strong predictor for LR and need re-excision that can be avoided for close margins. © 2014 Elsevier Ltd.

Introduction: Nipple-areola sparing mastectomy (NSM) is increasingly used in patients with non-locally advanced breast carcinoma. Literature data on the preoperative assessment of the nipple-areola complex (NAC) are inconsistent. Patients and methods: Out of 1359 patients submitted to total mastectomy between 2001 and 2010, we selected 61 patients whose pre-operative mammogram (MX) was available (MX group) and 39 patients who underwent preoperative breast magnetic resonance imaging (magnetic resonance imaging (MRI) group). The rate of NAC involvement, the value of MX and MRI to predict NAC involvement and the performance of the Schecter's and Loewn's algorithms for the prediction of NAC involvement were evaluated. Results: In the combined MX and MRI groups, NAC involvement was found in 14% of the cases. At univariate analysis, tumour stage (p value: 0.03), central tumour location (p value: 0.004), presence of NAC retraction (p value: 0.001) and tumour-NAC distance (p value: 0.006) were associated with NAC involvement, but only the latter parameter retained statistical significance at multivariate analysis (p value: 0.05). Tumour-NAC distance was a key predictor of NAC involvement, with a negative predictive value of 94% for MX and of 100% for MRI when the cut-off was set at 10 mm. Overall, the performance of Schecter's and Loewn's algorithms was respectively lower and similar as compared to the original series. Conclusions: Occult tumour involvement of the NAC is detected in a minority of breast cancer patients submitted to mastectomy. A tumour-NAC distance ≥10 mm by MRI may help select patients candidate to NSM. © 2012 Elsevier Ltd. All rights reserved.

The association of endometriosis and ovarian malignancy is about 1%, with a peak incidence in patients over 45 years. The best way of treating peri- and post-menopausal women with endometriosis is still a very controversial issue. We report two cases of peri-menopausal women in which endometriosis was associated to ovarian malignancy. The first case was a 49-year-old woman who underwent laparoscopic oophorectomy for an ovarian endometrioid cyst. Definitive histology showed ovarian endometrioid cyst with endometrioid and clear cell carcinoma. Subsequently, surgical restaging was performed. The other case was a 49-year-old woman who underwent hysterectomy and bilateral oophorectomy for an ovarian mass suggestive of endometriosis and uterine myomas. At frozen section examination, ovarian adeno-carcinoma was found and staging procedure was performed. Definitive histology showed carcinosarcoma of the ovary with areas of endometriod adenocarcinoma. Given the non-infrequent association between ovarian endometriosis and cancer, more data are needed to decide for an aggressive or conservative approach to peri-menopausal endometriosis.

Background: Nipple-areola complex sparing mastectomy (NSM) with immediate implant reconstruction has been recently introduced for breast cancer patients who are not candidates for breast preserving surgery. As the cosmetic results in moderately ptotic breasts may not be optimal, a modified NSM with a periareolar pexy (PP-NSM) was introduced at our Institution. Patients selection criteria and complication rates of PP-NSM were prospectively recorded and compared with those of the classical NSM. Results: Over a period of 11 months, 22 PP-NSMs and 35 NSMs were performed. The mean jugular-nipple distance was significantly longer in the PP-NSM as compared with the NSM (22.6 vs. 19.6 cm; p = 0.000), whereas the mean inframammary fold-areola distance was superimposable (5.4 cm). The periareolar mastopexy led to a mean cranial transposition of the nipple-areola complex (NAC) of 2.2 cm (range 1.5-4 cm). Mean breast weight was significantly higher in the PP-NSM as compared with the NSM cohort (336 vs. 236 g; p = 0.003). The only case of total NAC necrosis occurred in the PP-NSM group. Partial NAC necrosis was slightly more frequent in the PP-NSM than in the NSM group (13.6% vs. 2.9%%; p = n.s.), possibly due to the higher percentage of smokers (41.0% vs. 14.0%; p = 0.05). Early cosmetic results were good to excellent from the surgeon's and the patient's point of view in over 80% of the cases. Conclusions: PP-NSM allows good cosmetic results and low complication rates in patients with moderately ptotic breasts requiring a mastectomy. In particular, PP-NSM seems to be a good option for women at high risk for developing breast cancer and for selected patients affected by non-locally advanced breast cancer. © 2011 British Association of Plastic, Reconstructive and Aesthetic Surgeons.
