To evaluate in vivo the efficacy of a newly developed breast radiofrequency (RF) ablation system in human small invasive breast carcinomas in terms of induction of complete tumor necrosis, reproducibility of ablation lesion size and shape, and cosmetic outcome. This study had institutional review board approval, and written informed consent was obtained. Thirty-four postmenopausal women (mean age, 53 years +/- 5 [standard deviation]; range, 49-62 years) with small (< or = 2 cm) biopsy-proved invasive ductal breast carcinomas were enrolled. RF energy was delivered through a 25-mm 15-gauge monopolar cool-tip needle electrode by using the temperature-controlled mode. Patients were divided into three groups according to their breast pattern as assessed at mammography. The volumetric size and geometry of the coagulation zone, together with ablation time, were determined. Histopathologic data were compared with postprocedural 3.0-T contrast material-enhanced magnetic resonance (MR) images. Cosmesis after RF ablation was assessed. Four weeks after RF ablation, patients underwent definitive surgery. All ablation procedures were performed successfully. For 97% of the procedures, nicotinamide adenine dinucleotide in its reduced form-diaphorase staining showed no evidence of viable cells. The mean induced ablation volume, as assessed with histologic analysis, was 12.50 cm(3) +/- 0.8. Tumor ablation volume on the postablation MR images showed good correlation with results of histopathologic analysis (r = 0.823, P < .005). No differences were observed in terms of duration of the procedure or ablation volume with respect to the glandular pattern of the breast (P > .05 for both). The general shape of the induced necrosis was close to a sphere in all cases. Cosmesis was excellent in 28 patients. A dedicated breast cool-tip RF ablation system can induce complete tumor necrosis and reproducible ablation volumes independently of breast glandular pattern, providing excellent cosmesis. Postablation MR images are a reliable tool in predicting histologic findings.

Background: The aim of this study was to compare the efficacy of radiofrequency ablation vs. cryoablation in the treatment of early breast cancer. Patients and Methods: 80 women (mean age 73 ± 5 years) with early breast cancer were retrospectively evaluated. 40 patients underwent cryoablation and 40 patients underwent radiofrequency ablation, both with sentinel lymph node excision. Tumor volume and histopatological data were compared by means of postprocedural 3.0-T magnetic resonance imaging (MRI). 30-45 days after the percutaneous ablation, all patients underwent surgical resection of the tumor. The mean follow-up was 18 months without any local recurrences. Results: Both techniques allow good correlation with histopathological data. In 75 patients (93.8%) we observed complete necrosis; in 5 cases there was residual disease in the postprocedural MRI and postoperative histological examination. There was a good correlation between MRI volume and histologic samples. Cosmetic results were good in all patients but 2. Conclusion: Both percutaneous radiofrequency ablation and cryotherapy are minimally invasive techniques with a good clinical and cosmetic outcome in selected cases. MRI examination is an ideal method to assess breast neoplasms in terms of quality and quantity as well as residual tumor extent after percutaneous ablation. Cryotherapy is the preferred method because of the analgesic effect of freezing with better patients compliance.

Background/Aim: Despite the large amount of clinical data available of Coronavirus-19 (COVID-19), not many studies have been conducted about the psychological toll on Health Care Workers (HCWs). Patients and Methods: In this multicentric descriptive study, surveys were distributed among 4 different Breast Cancer Centers (BCC). BCCs were distinguished according to COVID-19 tertiary care hospital (COVID/No-COVID) and district prevalence (DP) (High vs. Low). DASS-21 score, PSS score and demographic data (age, sex, work) were evaluated. Results: A total of 51 HCWs were analyzed in the study. Age, work and sex did not demonstrate statistically significant values. Statistically significant distribution was found between DASS-21-stress score and COVID/No-COVID (p=0.043). No difference was found in the remaining DASS-21 and PSS scores, dividing the HCWs according to COVID-19-hospital and DP. Conclusion: Working in a COVID-19-hospital represents a factor that negatively affects psychosocial well-being. However, DP seems not to affect the psychosocial well-being of BCC HCWs. During the outbreak, psychological support for low risk HCWs should be provided regardless DP.

Background/Aim: The COVID-19 lockdown includes restrictive measures and temporary health system reorganization. Resources were shifted to COVID-19 patients, screening programs were temporary suspended, and oncological care suffered slow-down. The aim of the study was to evaluate the impact of these measures on breast cancer patients. Patients and Methods: All breast cancer patients referred to our unit from February 21, 2019 to February 21, 2021 were enrolled. Type of treatments and surgery, TNM, tumor diameter, and predictive and prognostic factors were analyzed. Results: Out of 445 patients with a breast cancer diagnosis, 182 (40.9%) were enrolled in the COVID-19 group (from February 21, 2010 to February 21, 2021). These patients were compared with 263 (59.1%) patients pre-COVID-19. Tumor diameters were bigger in the COVID-19 group. Type of surgery and N staging were statistically significantly different. Extreme advanced disease incidence was significantly different between the groups (2.7% COVID-19 group vs. 0 pre-COVID-19 group, p=0.011). Incidence of post-surgical radiation-therapy was higher in the COVID-19 group. Other variables analyzed were comparable without a statistically significant difference. Conclusion: COVID-19 led to increased tumor dimensions, advanced N-staging, and increased need for adjuvant treatments in breast cancer.
