Endometriosis is protective



Ovarian cancer prognosis in women with endometriosis. A retrospective nationwide cohort study of 32,419 women.

         Endometriosis is associated with ovarian cancer; the risk of developing ovarian cancer is put at between 5 and 10%. Often the cancer is of the subtypes endometrioid or clear cell cancer. These cancers present earlier and are commonly unilateral.

         It was thought that women who develop ovarian cancer having previously been diagnosed with endometriosis had better survival rates. This study of the Dutch cancer population revealed 32,000 case of ovarian cancer, 6% had suffered from endometriosis prior to diagnosis.

         Those women who had been endometriosis patients were younger and had more easily resected cancer on presentation. Even after allowing for the bias due to the more easily treated disease, having been diagnosed with endometriosis was protective, with survival being two times better than that of other patients who had not.

An impossible dream?

Reducing ovarian cancer mortality through screening: an impossible dream? https://tinyurl.com/4524jh8f The history of screening tests for ovarian cancer is not good. Two huge trials; the UKCTOCS with  more than 200,000 recruits over 20 years and the PLCO trial with more than 3 million pathology samples  sho wed no benefit in terms of survival from ovarian cancer. This article addresses the stages of ovarian cancer using  an alternative approach called the clinical continuum,  which divides cancer into 3 phases ,  no disease, pre-clinical  (detectable disease) , and  clinical (overt cancer). Obviously for a screening test to be effective ,   cancer needs to be detected before the clinical  phase. However, ovarian cancer is unlike other cancer in that the precursor occurs in the fallopian tube and the re is an argument to say that ,  by the time ovarian cancer has occurred ,  it is always advanced and metastatic .   T his time in...

How common is complete clearance?

Surgical and blood-based minimal residual disease in patients with ovarian cancer after frontline therapy: Clinical outcomes and translational opportunities https://tinyurl.com/4698cc7c In the treatment of ovarian cancer, the most important determinant of survival is the effectiveness of the initial surgical procedure. The aim is complete clearance and for about 80% of women no residual cancer can be detected either by CT scan or plasma CA 125 levels. Despite this only about 20% of women will have be en cured sugge sting that residual cancer is present despite evidence to the contrary. This study shows the true rate of minimal residual disease (MRD) , by measuring c i rculatin g tumour DNA (CT DNA) , and by repeat “second look” laparoscopy after completion of surgery and chemo. Findings from the study showed that of 95 patients thought to have had a complete clearance at initial surgery almost half had MRD with abnormal CT DNA or second look laparoscopy. These women had ...

Exploring causal relationships between brain imaging-derived phenotypes and ovarian cancer risk: a bidirectional Mendelian randomization https://tinyurl.com/yhfkpwyb One of the perplexing aspects of ovarian cancer is why there is individual variation between those who do have cancer and those who don’t . It would be expected that women with high risk due to genetic mutation such as BR CA2 would all eventually succumb to breast or ovarian cancer. However, many (about 2 0%) , do not. This study suggests that brain structure and function may be part of the reason this is so. Magnetic Resonance Imaging (MRI) is able in a non-invasive way to identify different brain shapes and anatomy . Using data from the UK Biobank study it has bee n possible to identify 12 distinct varieties of brain anatomy which have an influence on ovarian cancer. Further investigation suggested distinct areas of brain cortex variation, with the right medial cortex being protective , and the right pre-cen...
