Concerns about the health of modern residential living are increasing. Social problems have occurred as a result of chemical products in the environment. While people are concerned about the use of chemical products, they generally are unaware of the formaldehyde (HCHO) and volatile organic compounds (VOCs) contained in chemical products. In addition, it has not been recognized that people are often also exposed to HCHO, VOCs, and hazardous materials that are released into the environment from multi-use facilities. Advanced studies on indoor air quality in multi-purpose multiuse facilities, such as beauty salons, print shops, nail salons, and dry cleaners due to their use of chemical products have not significantly progressed, even though similar studies on facilities such as subway stations, hospitals, and transport terminal facilities have significantly progressed. The aim of the present study is to inform workers of the risks of the high frequency use of HCHO and VOCs in various chemicals such as laundry chemicals used in various facilities.

Purpose: In patients with locally advanced breast cancer, neoadjuvant chemotherapy is widely used. It has a distinct advantage in the downstaging of the primary tumor and provides important information about treatment response. With its increasing usage, concerns over the appropriate management of the axilla have emerged. In this study, we compared oncological outcomes of conventional axillary lymph node dissection (ALND) over axillary sampling (AS) with radiotherapy (RT) in patients who received neoadjuvant chemotherapy. Methods: In this retrospective study, we included female patients with triple negative breast cancer (TNBC) and HER2 type breast cancer who underwent breast and axillary surgery after neoadjuvant chemotherapy between May 2011 to December 2016. A total of 89 patients’ medical records were eligible for analysis. We defined AS as removal of at least four axillary lymph nodes located near the sentinel lymph nodes without full exposure of the axillary vein, long thoracic nerve, and thoracodorsal nerve. Results: The median follow-up period was 47.00 months. The disease-free survival was 69.66 months in the AS with RT group and 69.02 months in the ALND group (p=0.280). The invasive disease-free survival was 75.16 months in the AS with RT group and 78.44 months in the ALND group (p=0.218). Conclusion: AS with radiotherapy might be a feasible surgical option in patients with TNBC and HER2 type breast cancer after neoadjuvant chemotherapy.
