RESUMO
Background: Breast cancer (BC) recurrence, defined as the reappearance of cancer in the ipsilateral breast after primary treatment, poses significant challenges in clinical management. Despite advances in treatment, recurrence rates persist, ranging from 0.6 to 1.5% annually, reaching 10-15% at 20 years. This study aims to analyze the surgical and oncological characteristics of patients with BC recurrence. Methods: This retrospective study includes 56 patients diagnosed with recurrent BC between October 2018 and April 2022. Data were collected from a prospectively maintained surgical database. A descriptive analysis was performed on the initial BC, and the recurrence, including surgical complications, was classified using the Clavien-Dindo system. The success rates of selective sentinel lymph node (SLN) biopsies and aberrant drainages were assessed based on previous surgeries. Results: The cohort included 55 females and 1 male, with a median age of 65.3 years. The mean time to BC recurrence was 11.5 years. Among them, 26.8% underwent breast-conserving surgery, 41.1% had a mastectomy, 21.4% had a mastectomy with reconstruction, and 10.7% had an excision over a previous mastectomy. An SLN biopsy was performed in 78.6% of cases, with higher success rates in those without a previous axillary lymph node dissection (85.7% vs. 63.2%). Aberrant drainage was more frequent in patients with a previous ALND (44.4% vs. 20%). The median follow-up was 41.3 months, with 10.7% experiencing a second recurrence. Conclusions: Repeat breast-conserving surgery with re-irradiation for ipsilateral recurrence is feasible and does not significantly increase complications. SLN biopsy is valuable for restaging and tailoring adjuvant therapies, with ALND not being necessary if re-SLN biopsy shows no drainage. The management of aberrant drainage remains controversial.
RESUMO
Background and Objective: De-escalation in breast cancer surgery has been a natural evolution since breast conserving surgery (BCS) was introduced in the early 1980s. From Halsted mastectomies to wide local excisions, we are facing nowadays the next trend in form of oncoplastic breast surgery. Oncoplastic breast surgery combines oncological principles with plastic surgery techniques to preserve the breast shape and appearance. The aim of this work is to review recent oncological and quality of live outcomes derived from oncoplastic techniques as well as offer a perspective about its implementation in breast cancer units. Methods: A literature review was conducted to explore the landscape of oncoplastic breast surgery. Key terms related to oncoplastic techniques and breast cancer were used in searches across databases such as PubMed, Embase and Cochrane Library. Inclusion criteria focused on recent articles discussing oncological and quality of life (QoL) outcomes, as well as perspectives on the role of oncoplastic surgery. Key Content and Findings: The research aims to contribute valuable insights into the efficacy and impact of oncoplastic surgery in the context of breast cancer treatment. In this new era of precision medicine, it is more than just healing patients; it is about improving their well-being. We ought to consider specific oncoplasty role in leading this paradigm shift. It is also relevant to define whether these new technical-demanding surgical options can be applied to all patients and if professional training performs adequately to current demands of personalized treatments. Conclusions: The global adoption of oncoplastic BCS is recommended due to its oncological safety and improvement in QoL compared to standard procedures. Emphasizing the need for skilled surgeons in complex cases, collaboration between breast surgeons and scientific societies is urged to certify ongoing educational training in oncoplastic techniques.
RESUMO
BACKGROUND: Adjuvant radiotherapy and hormonotherapy after breast-conserving surgery (BCS) in ductal carcinoma in situ (DCIS) have been shown to reduce the risk of local recurrence. To predict the risk of ipsilateral breast tumor relapse (IBTR) after BCS, the Memorial Sloan Kettering Cancer Center (MSKCC) developed a nomogram to analyze local recurrence (LR) risk in our cohort and to assess its external validation. METHODS: A historical cohort study using data from 296 patients treated for DCIS at the Hospital Clínic of Barcelona was carried out. Patients who had had a mastectomy were excluded from the analysis. RESULTS: The mean age was 58 years (42-75), and the median follow-up time was 10.64 years. The overall local relapse rate was 13.04% (27 patients) during the study period. Actuarial 5- and 10-year IBTR rates were 5.8 and 12.9%, respectively. The external validation of the MSKCC nomogram was performed using a multivariate logistic regression analysis on a total of 207 patients, which did not reach statistical significance in the studied population for predicting LR (p = 0.10). The expression of estrogen receptors was significantly associated with a decreased risk of LR (OR: 0.25; p = 0.004). CONCLUSIONS: In our series, the LR rate was 13.4%, which was in accordance with the published series. The MSKCC nomogram did not accurately predict the IBTR in this Spanish cohort of patients treated for DCIS (p = 0.10).
RESUMO
Background: Recent studies have shown preliminary evidence that vaccination against human papillomavirus (HPV) could decrease the risk of persistent/recurrent HSIL in women treated for high-grade cervical intraepithelial lesion (HSIL). We aimed to determine the benefits of HPV vaccination in patients undergoing conization for HSIL in real-life conditions and evaluate vaccination compliance associated with different funding policies. Methods: From January 2013 to July 2018, 265 women underwent conization in our center. From January 2013 to July 2017, treated patients (n = 131) had to pay for the vaccine, whereas after July 2017 the vaccine was publicly funded and free for treated women (n = 134). Post-conization follow-up controls were scheduled every six months with a Pap smear, HPV testing, and a colposcopy. Results: 153 (57.7%) women accepted vaccination (vaccinated group), and 112 (42.3%) refused the vaccine (non-vaccinated group). Persistent/recurrent HSIL was less frequent in vaccinated than in non-vaccinated women (3.3% vs. 10.7%, p = 0.015). HPV vaccination was associated with a reduced risk of persistent/recurrent HSIL (OR 0.2, 95%CI: 0.1-0.7, p = 0.010). Vaccination compliance increased when the vaccine was publicly funded (from 35.9% [47/131] to 79.1% [106/134], p < 0.001). Conclusions: HPV vaccination in women undergoing conization is associated with a 4.5-fold reduction in the risk of persistent/recurrent HSIL. Vaccination policies have an important impact on vaccination compliance.
