Does FDG PETCT have a predictive value for neoadjuvant chemotherapy response in nonmetastatic breast cancer?

Background: A pathological complete response (pCR) rate after neoadjuvant chemotherapy (NAC) is important for the prognosis of early-stage breast cancer. The prediction of an NAC response plays a key role in managing neoadjuvant treatment.

Aims: The aim of this study is to investigate the predictive value of the baseline PETCT FDG (F-18 fluoro-deoxy-glucose (FDG) positron emission tomography/computed tomography) SUVmax (the maximum standardized uptake value) for pCR after NAC in early-stage breast cancer.

Evaluation of digit ratio (2D:4D) in breast cancer patients.

Breast cancer is a hormone-dependent cancer. Hormonal exposure begins in the intrauterine period and continues in later years of life. 2D:4D ratio is accepted as an indicator of this exposure.

Evaluation of the relationship between toxicity of cyclin-dependent kinase 4/6 inhibitors and body surface area.

Objective: This study aimed to evaluate the relationship between the toxicity of cyclin-dependent kinase 4/6 inhibitors and body mass index and body surface area.

Methods: A total of 83 patients were included in the study. Patients were divided into 4 groups as 18-24.
