P052. Feasibility and safety of breast cancer surgery during the SARS-COV-2 pandemic

Introduction: During the SARS-CoV-2 pandemic, services in the NHS were re-configured including cancer surgery. We present our experience in breast cancer surgery performed at the private hospital considered as a COVID-19 free hub to cope with limited resources and the acute hospital.

Safety of Breast Cancer Surgery as A Daycare Procedure – Results from a Community Hospital in a Lower Middle-Income country.

Background: Breast Cancer is the most common cancer among women in the world. It's also the 2nd leading cause of death. The mortality to incidence ratio is higher in LMIC and LIC. Mastectomy and axillary lymph nodes dissection remains the standard of care combined with systemic Chemotherapy. Treatment of breast cancer is an economic burden on low middle income countries and leads to financial stress on the patients. Efforts should be made to cut down the costs of this curable disease. This study aims to assess the safety of breast cancer surgery as a daycare procedure in a low middle income country.

A prospective cohort study of the safety of breast cancer surgery during COVID-19 pandemic in the West of Scotland

IntroductionIn order to minimise the risk of breast cancer patients for COVID-19 infection related morbidity and mortality prioritisation of care has utmost importance since the onset of the pandemic. However, COVID-19 related risk in patients undergoing breast cancer surgery has not been studied yet. We evaluated the safety of breast cancer surgery during COVID-19 pandemic in the West of Scotland region. MethodsA prospective cohort study of patients having breast cancer surgery was carried out in a geographical region during the first eight weeks of the hospital lockdown and outcomes were compared to the regional cancer registry data of pre-COVID-19 patients of the same units (n = 1415). Results188 operations were carried out in 179 patients. Tumour size was significantly larger in patients undergoing surgery during hospital lockdown than before (cT3-4: 16.8% vs. 7.4%; p < 0.001; pT2 – pT4: 45.5% vs. 35.6%; p = 0.002). ER negative and HER-2 positive rate was significantly higher during lockdown (ER negative: 41.3% vs. 17%, p < 0.001; HER-2 positive: 23.4% vs. 14.8%; p = 0.004). While breast conservation rate was lower during lockdown (58.6% vs. 65%; p < 0.001), level II oncoplastic conservation was significantly higher in order to reduce mastectomy rate (22.8% vs. 5.6%; p < 0.001). No immediate reconstruction was offered during lockdown. 51.2% had co-morbidity, and 7.8% developed postoperative complications in lockdown. There was no peri-operative COVID-19 infection related morbidity or mortality. Conclusionbreast cancer can be safely provided during COVID-19 pandemic in selected patients.

Thirty-day postoperative morbidity and mortality in elderly women with breast cancer: an analysis of the NSQIP database.

Postoperative complication rates for elderly women undergoing breast cancer surgery have not been well studied. We describe the postoperative complication rates of elderly (≥ 70 years) women with breast cancer and compare them with young (40-69 years) women. Data were extracted from the National Surgical Quality Improvement Program database (2004-2014). We included women with invasive breast cancer who underwent surgery. Outcomes were 30-day postoperative morbidity and mortality(complications), which were compared between young and elderly women. Morbidity was categorized using the Surgical Risk Preoperative Assessment System (SURPAS) clusters. We identified 100,037 women of which 26.7% were elderly. Compared to young women, elderly women were more likely to have more comorbidities and undergo breast-conserving surgery, but less likely to undergo lymph node surgery, breastreconstruction, and neoadjuvant chemotherapy. While the 30-day overall morbidity rate was not significantly different between young and elderly women (3.9 vs. 3.8%, p = 0.2), elderly women did have significantly higher rates of pulmonary, cardiac (arrest and myocardial infarction), venous thromboembolic, and neurological morbidity. Specific morbidities that showed significantly lower rates among elderly women included wound disruption and deep and organ space surgical site infection. Any cause death was significantly higher in elderly compared to young women (0.2 vs. 0.05%, p < 0.001). While some specific 30-day postoperative morbiditieswere more often seen in elderly women, theoverall 30-day postoperative complicationrate was very low. These data support the safety of breast cancer surgery in well-selected elderly patients.

Breast cancer surgery during pregnancy.

1127 Background: There is limited literature on breast surgery during pregnancy. We present prospective registry data on 88 breast cancer patients who underwent breast cancer surgery during pregnancy. Methods: The Cancer and Pregnancy Registry is a voluntary international registry that prospectively collects the clinical course, treatment, and disease outcome of women diagnosed with cancer during pregnancy and the perinatal and neonatal outcomes of their children. Results: We identified 88 patients who were diagnosed with breast cancer and had surgery while pregnant. 59 patients (67%) underwent Mastectomy while29 patients (32%) underwent breast conserving surgery (BCS). Out of 43 patients who underwent BCS as their first surgery 13 patients (30.23%) required subsequent mastectomy during pregnancy. 15 patients (34.88%) from the BCS group and 4 patients (8.69%) from the Mastectomy group had positive margins. There was no significant difference between patients who underwent mastectomy vs BCS based on Age (34.67 vs 34.72 P: 0.97), gestational age at surgery (14.05 vs 16.06 P: 0.23) or ER positivity (47.5% vs 46.4% P: 0.93). 2 patients had neo-adjuvant chemotherapy. 17 patients (19.31%) had sentinel lymph node biopsy. 37 patients (42%) had a pregnancy complication. There was no difference in the rate of complication based on mastectomy vs BCS(45.8% vs 34.5% P: 0.31). There was only 1 patient (from mastectomy group) that delivered within 2 weeks of surgery. Of the 17 patients (19.3%) with spontaneous preterm delivery, there was no difference between Mastectomy and BCS group (22% vs 13.2% P: 0.41). Of the 25 patients (28.4%) with birth complications, there was no significant difference between mastectomy vs BCS (30.5% vs 24.1% P: 0.53). There was also no difference in mean birth weight between the groups (2598 grams vs 2672.3 grams P: 0.57). Conclusions: The data supports the safety of breast cancer surgery during pregnancy. In addition, there were no identified adverse effects in patients who underwent BCS as opposed to mastectomy. Of note, only 19% of patients underwent sentinel node biopsy which is considered the standard of care in early breast cancer patients regardless of pregnancy status.
