Examples of oophorectomy


oophorectomy isn’t in the Cambridge Dictionary yet. You can help!
These findings corroborate the hypothesis that hysterectomy without oophorectomy does not reduce ovarian function or increase bone turnover and bone loss.
Of the 241 women with no history of breast cancer or prophylactic mastectomy, oophorectomy also reduced the incidence of breast cancer (42.3% vs. 21.2%, hazard ratio 0.47).
Adjuvant tamoxifen use following initial breast cancer diagnosis, oophorectomy, parity, smoking, radiotherapy, and chemotherapy were all examined.
These effects remained significant in a multivariate analysis, in which the significant effects found for family history of breast cancer, early menarche, oophorectomy and hypothyroidism were controlled.
After the exclusion of the six women who were diagnosed with cancer at surgery, oophorectomy reduced the risk of ovarian cancer by 96%.
With a median follow-up of only 24 months, this prospective study supports an early reduction in breast and ovarian cancer risk with prophylactic oophorectomy.
In this cohort, 43% of women had undergone oophorectomy and 30% had taken tamoxifen.
This study also noted a reduction in contralateral breast cancer in patients who received oophorectomy.
Of the 98 women who opted for prophylactic oophorectomy, 3 were later diagnosed with breast cancer and one patient developed peritoneal cancer.
Ovarian oestrogen production in premenopausal breast cancer patients can be irreversibly ablated with either oophorectomy or ovarian irradiation.

This type of cancer is unrelated to oophorectomy, pregnancy, oestrogen-secreting tumours or (so far as is known) treatment with stilboestrol.
Infection may, in severe cases, result in pelvic adhesions, hysterectomy, and/or oophorectomy, with resultant loss or reduction in fertility.
The high incidence of ipsilateral breast recurrence is likely to be reduced to an acceptable level with the use of tamoxifen or oophorectomy.
Further work needs to be done to determine whether factors, such as earlier age of use or prior prophylactic oophorectomy impact tamoxifen's effect.
As these factors are associated with poor prognosis of diseasefree survival, several strategies are pursued to reduce mortality: prophylactic surgery (mastectomy, oophorectomy), chemoprevention, and surveillance.
With a median follow-up of 8 years, two women developed papillary serous peritoneal carcinoma after oophorectomy and 58 controls were diagnosed with ovarian cancer.
