A new study from Cedars-Sinai Medical Center found that obesity can affect the progression and outcome of ovarian cancer, with obese women experiencing shorter survival times and earlier death. The study suggests that excess fat may be excreting a hormone or protein that causes ovarian cancer cells to grow more aggressively.
A new study found significant differences in histological types of epithelial ovarian cancer depending on body mass index (BMI), with obese women having a worse outcome. Higher BMI was also associated with decreasing survival rates and increased risk of mortality.
A large population-based study found that 2.4% of breast-cancer cases carried BRCA1 mutations and 2.3% carried BRCA2 mutations, with variations in mutation rates among different racial and ethnic groups. The study also identified predictors of carrying these mutations, including family history and age at diagnosis.
Researchers at the University of Texas M. D. Anderson Cancer Center have developed a nanoparticle delivery system that targets ovarian cancer cells, reducing tumor size and incidence by up to 98%. The fatty spheres loaded with siRNA also attack the tumor's blood supply, inducing cell suicide and increasing cell death among cancer cells.
A phase III study found that adding topotecan to standard chemotherapy for ovarian cancer does not increase overall survival or reduce cancer recurrence. The treatment instead leads to more blood-related toxicities and infections.
A preclinical study by the University of Texas M. D. Anderson Cancer Center found that chronic stress hormones stimulate tumor growth and spread in mice with ovarian cancer. Reducing stress using a medication commonly prescribed for heart disease slows tumor growth.

Radical surgery was shown to improve five-year survival rates by 44% compared to non-radical surgery, indicating it aids in survival rather than increasing risk.
The National Cancer Institute has issued a clinical announcement recommending a combination of chemotherapy regimens for women with advanced ovarian cancer. The treatment involves delivering chemotherapy directly into the abdominal cavity (intraperitoneal, or IP) in addition to traditional IV chemotherapy. This approach appears to be m...
A new study confirms the survival benefit of intra-abdominal chemotherapy, also known as intraperitoneal (IP) chemotherapy, for most women with advanced ovarian cancer. The treatment has shown an overall survival period of approximately one year after optimal debulking surgery.
A seven-year study of over 400 patients found that delivering chemotherapy directly into the abdomen via a catheter increases survival and relapse-free survival rates compared to intravenous chemotherapy alone. However, side effects are significantly worse for the abdominal group.

A study found that a thorough family history is an effective measure for cancer risk, with 20% of women with breast or ovarian cancer having a high risk of BRCA1/BRCA2 mutations. Women of Ashkenazi ancestry were more likely to have high-risk family histories than those of non-Ashkenazi ancestry.
A study of 199 families with multiple cases of breast cancer found that women from these families do not have an increased risk of ovarian cancer. Despite this, the genetic mechanism for up to half of hereditary breast cancer remains unknown, prompting ongoing research at Memorial Sloan Kettering Cancer Center.
The US Task Force does not recommend routine screening for breast cancer gene mutations in women without a specific family medical history. However, they do suggest screening for women with a history of Ashkenazi Jewish descent, young-onset breast cancer, or multiple relatives with breast and ovarian cancer.
A study found that the BRCA2 gene mutation significantly increases cancer risk in men, with higher rates of prostate, pancreatic, pharyngeal and bone cancers. The mutation is associated with an increased risk of developing these cancers, particularly among younger men.
