Association between high body mass index and prognosis of patients with early-stage breast cancer: A systematic review and meta-analysis.

A high body mass index (BMI) can indicate overweight or obesity and is a crucial risk factor for breast cancer survivors. However, the association between high BMI and prognosis in early-stage breast ... The PubMed, Embase, and Cochrane Library databases and proceedings of major oncological conferences related to the effects of BMI on the prognosis of breast cancer were searched up to November 2021. F... Twenty retrospective cohort studies with 33,836 patients with EBC were included. Overweight patients had worse DFS (HR: 1.16, 95% CI: 1.05-1.27,... Compared with normal weight, increased body weight (overweight, obesity, and high BMI) led to worse DFS and OS in patients with EBC. Once validated, these results should be considered in the developme...

Oncologic and obstetric outcomes of early-stage epithelial ovarian cancer patients who underwent fertility-sparing surgery: A retrospective study.

This study aimed to assess the long-term oncologic and obstetric outcomes of women with epithelial ovarian cancer who underwent fertility-sparing surgery.... A total of 68 patients observed between March 2007 and July 2021 were included in this retrospective study. Unilateral salpingo-oophorectomy and uterine preservation with staging surgery were the main... The median age of the patients was 30.5 years. The median follow-up time was 60.5 months. Disease recurrence occurred in 15 (22.1%) of the patients. Five-year disease-free survival and overall surviva... Fertility preservation is safe for invasive epithelial ovarian cancer at early stages for women in the reproductive era. Disease recurrence and OS results are similar to standard treatment at early st...

The Impact of Race and Age on Response to Neoadjuvant Therapy and Long-Term Outcomes in Black and White Women with Early-Stage Breast Cancer.

There are a paucity of data and a pressing need to evaluate response to neoadjuvant chemotherapy (NACT) and determine long-term outcomes in young Black women with early-stage breast cancer (EBC).... We analyzed data from 2,196 Black and White women with EBC treated at the University of Chicago over the last 2 decades. Patients were divided into groups based on race and age at diagnosis: Black wom... Young Black women had the highest risk of recurrence, which was 22% higher than young White women (p=0.434) and 76% higher than older Black women (p=0.008). These age/racial differences in recurrence ... Black women with EBC had significantly worse outcomes compared to White women in our cohort study. There is an urgent need to understand the disparities in outcomes between Black and White breast canc...

Visualization of tumor hypoxia and re-oxygenation after stereotactic body radiation therapy in early peripheral lung cancer: A prospective study.
