Endometriosis still takes 8 years to diagnose - and treatment options remain largely ineffective

MAASTRICHT, 15 SEPTEMBER 2005: Attendees at the 9th World Congress on Endometriosis heard more about the challenge, which endometriosis presents for the millions of women worldwide, who live with this chronic disease.

The results of a global survey, completed by 7,025 women with endometriosis [1], were announced today by Lone Hummelshøj, co-founder of the Danish Endometriosis Society, as part of a workshop on pain and quality of life.

The survey, which was commissioned by the UK Endometriosis All Party Parliamentary Group, clearly demonstrated that much more is required to deal with the effects of endometriosis, which can wreck relationships, destroys careers, contribute to infertility, and can have an untold impact on quality of life.

The average diagnostic time from when women first presented to their GP/primary physician with symptoms was a staggering eight years.

Furthermore, the worrying lack of awareness of endometriosis leads to an additional three year delay before women with symptoms seek help in the first place, resulting in an overall diagnostic delay of 11 years - during which almost 50% of women had to see five doctors or more in order to obtain a diagnosis.

Less than 50% felt that their GP took them seriously when they first presented with symptoms.

65% were told they had another condition prior to a correct diagnosis.

These survey results are almost identical to those presented by the Endometriosis Association in 1998 following a similar study amongst 4,000 of their North American members [2]. One would have hoped to have seen an improvement in time to diagnosis in the past seven years, as well as improvement in the support and help to sufferers, but this does not appear to be the case.

Inconsistent levels of treatment show that on average only a third of the respondents felt that their treatment was effective, and less than 50% felt that their endometriosis was under control.

PAINKILLERS appear to be only somewhat effective in 21% of the 6043 women, who had tried these, with a varying effect depending on which type of pain killer used.

SURGERY appears to be effective to some extent in 30% of the 5478 women, who had tried this treatment.

However, two presentations in the pain and quality of life workshop indicated that if women are treated by surgeons specialising in endometriosis, these results were much more favourable, with up to 80% reporting an improvement in pain, sexual activity, and quality of life [3] and a cumulative pregnancy rate of 31%-70% from 1-4 years following laparoscopic excision of endometriosis [4].

HORMONES were effective to some degree in 37% of the 5669 women, who had tried these.

However, there were varying degrees of effectiveness depending on the type of hormone tried, with different types of progestins appearing to be the most effective and best tolerated drugs.

COMPLEMENTARY THERAPIES had been tried by 2716 of the women in this sample, and showed that 33% had some effect, with no great variance depending on which type of therapy they had tried.

With most treatments being largely ineffective, daily pain becomes a fact of life for many women with endometriosis, and the study showed that:

  • 85% suffered pain at menstruation
  • 63% reported pain with sexual intercourse
  • 58% had pain with ovulation

25% indicated that they suffered pain throughout the monthly cycle, with 72% reporting that endometriosis had interfered with their personal relationships, including causing the break-up of marriages (10%) and difficulty in looking after their children (11%).

Worryingly, and worth noting, is that about 90% of the under 19s, had taken time off education due to endometriosis with an average of 5+ days a month.

Comparing these survey results with data from the early-mid 80s (n=3020) and from 1998 (n=4000) has only validated the fact that independent study samples from the past 25 years show that 74-79% of women with endometriosis are at times unable to carry on normal work due to their symptoms.

From the 2005 study, for those who lost time at work due to their endometriosis, the average loss was 54 days a year with an obvious, yet unknown, financial implication - to society and to themselves.

36% have had their jobs affected (n=2518), and 41% of those had given up or lost their jobs due to illness; 37% had reduced their working hours; and 23% had changed their jobs.

 

In conclusion Lone Hummelshøj said: "Endometriosis remains a disease which is still largely surrounded by taboos and myths. This data highlights areas that have a significant impact on patients' quality of life, and which need to be addressed. To do so a close partnership between physicians and patients is essential in order to provide the specialised care, which is so important for those with this condition. We need to aid women to talk openly about their individual needs and to look beyond the traditional treatment team, if necessary, in order to meet these. The theme for this congresss - the patient as a partner - has gone a long way to emphasise this necessity".

John McDonnell, MP for Hayes and Harlington and secretary of the Endometriosis All Party Parliamentary Group, says: “These results were deeply shocking and disappointing and clearly unacceptable that women with endometriosis are still suffering in silence and waiting far too long to be referred and to receive a diagnosis, resulting in maybe millions of women suffering unnecessary pain, distress and isolation.”

The survey is ongoing and data continues to be reviewed for regular updating.

The average age globally was 32 years, and was similar in each country/region. There were no real significant differences in results by ethnicity.

Almost half (49%) of responses came from the UK, 18% from North America, 12% from the Nordics, 17% from elsewhere in Europe and 4% from elsewhere in the world.
