Does timing of neoadjuvant chemotherapy influence the prognosis in patients with early triple negative breast cancer?

Purpose For patients with triple negative breast cancer (TNBC), the optimal time to initiate neoadjuvant chemotherapy (TTNC) is unknown. This study evaluates the association between TTNC and survival in patients with early TNBC. Methods A retrospective study using data from of a cohort of TNBC patients diagnosed between January 1, 2010 to December 31, 2018 registered in the Tumor Centre Regensburg was performed. Data included demographics, pathology, treatment, recurrence, and survival. Interval to treatment was defined as days from pathology diagnosis of TNBC to first dose of neoadjuvant chemotherapy (NACT). The Kaplan–Meier and Cox regression methods were used to evaluate the impact of TTNC on overall survival (OS) and 5 year OS. Results A total of 270 patients were included. Median follow up was 3.5 years. The 5-year OS estimates according to TTNC were 77.4%, 66.9%, 82.3%, 80.6%, 88.3%, 58.3%, 71.1% and 66.7% in patients who received NACT within 0–14, 15–21, 22–28, 29–35, 36–42, 43–49, 50–56 and > 56 days after diagnosis. Patients who received systemic therapy early had the highest estimated mean OS of 8.4 years, while patients who received systemic therapy after more than 56 days survived an estimated 3.3 years. Conclusion The optimal time interval between diagnosis and NACT remains to be determined. However, starting NACT more than 42 days after diagnosis of TNBC seems to reduce survival. Therefore, it is strongly recommended to carry out the treatment in a certified breast center with appropriate structures, in order to enable an adequate and timely care

Perimenopause and Postmenopause - Diagnosis and Interventions. Guideline of the DGGG and OEGGG (S3-Level, AWMF Registry Number 015-062, September 2020).

Aim The aim of the interdisciplinary S3-guideline Perimenopause and Postmenopause - Diagnosis and Interventions is to provide help to physicians as they inform women about the physiological changes which occur at this stage of life and the treatment options. The guideline should serve as a basis for decisions taken during routine medical care. This short version lists the statements and recommendations given in the long version of the guideline together with the evidence levels, the level of recommendation, and the strength of consensus. Methods The statements and recommendations are largely based on methodologically high-quality publications. The literature was evaluated by experts and mandate holders using evidence-based medicine (EbM) criteria. The search for evidence was carried out by the Essen Research Institute for Medical Management (EsFoMed). To some extent, this guideline also draws on an evaluation of the evidence used in the NICE guideline on Menopause and the S3-guidelines of the AWMF and has adapted parts of these guidelines. Recommendations Recommendations are given for the following subjects: diagnosis and therapeutic interventions for perimenopausal and postmenopausal women, urogynecology, cardiovascular disease, osteoporosis, dementia, depression, mood swings, hormone therapy and cancer risk, as well as primary ovarian insufficiency
