To the best of our knowledge, only 17 patients have been described in the PubMed database. Case Report: Here, we report a primary breast mucinous cystadenocarcinoma with endocervical-like mucinous epithelium in a 62-year-old woman. The patient was followed for 5 months without any adjuvant treatment and she continues to be disease free. Conclusions: Primary breast mucinous cystadenocarcinoma usually displays unique pathologic and immunohistochemical characteristics simulating its ovarian counterparts; it seems to have a good prognosis after complete resection.

For patients with early stage breast cancer, breast-conserving surgery followed by radiation therapy has been definitively validated as a safe alternative to radical mastectomy, with similar survival rates, better cosmetic outcomes and acceptable rates of local recurrence. Thanks to the improvements in diagnostic work-up, as well as the wider diffusion of screening programs and efforts in patient and physician education, tumors are more often detected at an early stage, furtherly facilitating the widespread use of breast conserving techniques. Breast-conserving surgery has been introduced also in the treatment of patients with locally advanced tumors after tumor downsizing with preoperative chemotherapy, with acceptable rates of ipsilateral breast tumor recurrence. When performing breast-conserving surgery all efforts should be made to ensure negative surgical margins ...

As a result, some patients receive axillary lymph node dissection (ALND) regardless of response to NACT, leading to a potential overtreatment. To better assess reliability and clinical significance of SLNB status on ycN0 patients, we retrospectively analyzed oncological outcomes of 399 patients treated between January 2016 and December 2019 that were either cN0-ycN0 (219 patients) or cN1/2-ycN0 (180 patients). The Endpoints of our study were to assess, furthermore than IR: oncological outcomes as Overall Survival (OS); Distant Disease Free Survival (DDFS); and Regional Disease Free Survival (RDFS) according to SLNB status. SLN identification rate was 96.8% (98.2% in patients cN0-ycN0 and 95.2% in patients cN+-ycN0). A median number of three lymph nodes were identified and removed. Among cN0-ycN0 p...

As regards breast cancer (BC), a clear link between microbiota and oncogenesis is still to be confirmed. Yet, part of the bacterial gene mass inside the gut, constituting the so called “estrobolome”, influences the sexual hormonal balance and, since the increased exposure to estrogens is associated with an increased risk, it may impact on the onset, progression, and treatment of hormonal dependent cancers, which account for more than 70% of all BCs. The hormonal dependent BCs are also affected by environmental and dietary endocrine disruptors and phytoestrogens which interact with microbiota in a bidirectional way: on one side disruptors can alter the composition and functions of the estrobolome, on the other the gut microbiota influences the metabolism of endocrine active food components. This review highlights the current evidence about the complex interplay between endocri...

Today's scenario however is in further evolution because of emerging data that suggest a personalized modulation of treatment. In this work we aimed to gather recent evidence supporting a prophylactic or conservative surgical approach in order to define the state of the art in today's treatment of BRCA carriers with breast cancer. EVIDENCE ACQUISITION We reviewed the literature to identify studies providing evidence on surgical treatment in breast cancer patients with BRCA 1 and 2 PVs. We included articles comparing outcomes between patients undergoing breast conserving surgery (BCS) and mastectomy, and articles investigating contralateral risk-reducing mastectomy (CRRM), with a particular focus on recent literature. International guidelines were also reviewed. EVIDENCE SYNTHESIS Optimal surgical management of BRCA PV carriers with breast cancer remains controversial. While the introduction of routine genetic testing has initially led surgeons to favor more radical treatments, recent literature provides evidence that a conservative approach is safe and feasible in selected cases. Guidelines are heterogeneous and provide guidance without constraining the surgeon. CONCLUSIONS Patients should undergo adequate genetic and surgical counseling in order to receive the best tailored surgical treatment. Because guidelines vary in different countries and provide no definite protocol, they highlight the importance of accurate surgical planning. Clinical, familial and psychosocial factors should be taken into account when approaching a BRCA PV carrier with breast cancer, in order to guarantee the best evidence-based patient care in an era of personalized treatment.

Although large clinical trials have shown no differences between the same systemic therapy given pre- or post-surgery on diseasefree and overall survival, neoadjuvant therapy may have several advantages. By downstaging of the tumor, chemotherapy can convert patients who are candidates for mastectomy to breast-conserving surgery candidates. Furthermore, it has potential to reduce excision volumes in patients with large cancer who are already candidates for breast conserving surgery improving cosmetic outcomes. Another surgical advantage is downstaging of the axilla so that lymph node dissection can be avoided in selected patients reducing surgical morbidity. Neoadjuvant therapy also allows to monitor response to therapy at an early stage; potentially allowing time and flexibility to switch therapies if patients do not respond. All early stage br...

The evolution from aggressive and mutilating treatment to conservative approach has been long, but constant, despite the controversies that appeared every time a new procedure came to light. Today, the aesthetic satisfaction of breast cancer patients coupled with the oncological safety is the goal of the modern breast surgeon. Breast-conserving surgery with adjuvant radiotherapy is considered the gold standard approach for patients with early stage breast cancer and the recent introduction of "oncoplastic techniques" has furtherly increased the use of breast-conserving procedures. Mastectomy still remains a valid surgical alternative in selected cases and is usually associated with immediate reconstructive procedures. New surgical procedures called "conservative mastectomies" are emerging as techniques that combine oncological safety and cosmesis by enti...

There is no evidence regarding their safety and efficacy after neoadjuvant chemotherapy (NAC). The aim of this study was to compare the oncological and aesthetic outcomes of this technique compared with those observed in mastectomy with immediate breast reconstruction (MIBR), in post-NAC patients undergoing surgery between January 2016 and March 2021. Local disease-free survival (L-DFS), regional disease-free survival (R-DFS), distant disease-free survival (D-DFS), and overall survival (OS) were compared; the aesthetic results and quality of life (QoL) were evaluated using BREAST-Q. A total of 297 patients were included, 87 of whom underwent OPSII and 210 of whom underwent MIBR. After a median follow-up of 39.5 months, local recurrence had occurred in 3 patients in the OPSII group (3.4%), and in 13 patients in the MIBR group (6.1%) (p = 0.408). The three-year L-DFS rates were 95.1% for ...
