“Waiting for Godot”: a commonsense approach to the medical treatment of endometriosis

Open access

Abstract

Conservative surgical treatment for symptomatic endometriosis is frequently associated with only partial relief of pelvic pain or its recurrence. Therefore, medical therapy constitutes an important alternative or complement to surgery. However, no available compound is cytoreductive, and suppression instead of elimination of implants is the only realistic objective of pharmacological intervention. Because this implies prolonged periods of treatments, only medications with a favourable safety/tolerability/efficacy/cost profile should be chosen. In the past few years, innumerable new drugs for endometriosis, which would interfere with several hypothesized pathogenic mechanisms, have been studied and their use foreseen. However, robust evidence of in vivo safety and efficacy is lacking and, at the moment, the principal modality to interfere with endometriosis metabolism is still hormonal manipulation. Regrettably, in spite of consistent demonstration of a major effect on pain even in patients with deeply infiltrating lesions, progestins are underestimated and dismissed in favour of more scientifically fashionable and up-to-the-minute alternatives. Moreover, oral contraceptives (OCs) dramatically reduce the rate of post-operative endometrioma recurrence and should now be considered an essential part of long-term therapeutic strategies in order to limit further damage to future fertility. Finally, women who have used OC for prolonged periods will be protected from an increased risk of endometriosis-associated ovarian cancer. To avoid the several subtle modalities for distorting facts and orientating opinions in favour of specific compounds, progestins and monophasic OC used continuously are here proposed as the reference comparator in all future randomized controlled trials on medical treatment for endometriosis.

TL;DR

This review argues that medical treatment for endometriosis should aim at long-term suppression rather than cure, and that progestins and continuous monophasic oral contraceptives (OCs) are effective, safe, inexpensive options that are underused. It proposes these as reference comparators in future randomized controlled trials and highlights postoperative OC use for preventing endometrioma and symptom recurrence.

Key findings

  • No available drug is cytoreductive; suppression is the only realistic objective, so prolonged therapy is needed. In nine controlled trials identified from 1990–2010, progestins and OCs relieved pain and were generally not inferior to danazol, GnRH agonists, and aromatase inhibitors.
  • Postoperative OC use dramatically reduced endometrioma recurrence in three controlled studies, with odds ratios from 0.04 (Takamura et al., 2009) to 0.32 (Seracchioli et al., 2010a). Two RCTs showed reduced dysmenorrhoea recurrence with postoperative progestin/OC versus expectant management (OR 0.14 and 0.32).
  • Recurrence after conservative surgery is common: 10% at 1 year, 25% at 3 years, and 45% at 5 years (Evers et al., 1991); >20% at 2 years and 40–50% at 5 years (Guo, 2009); endometrioma recurrence reportedly 30–50% after 2–5 years.
  • Costs are substantial: global endometriosis cost was $18.8–$22 billion per year based on 2002 US data; annual therapy costs ranged from €18 for low-dose norethisterone acetate to about €2100 for aromatase inhibitors or GnRH agonists, and about €4200 if combined.

Methods

  • Narrative review/opinion article; no primary data. A MEDLINE search from January 1990 to July 2010 in English (MeSH terms: endometriosis, progestins, OCs, medical therapy) identified nine controlled trials comparing a progestin or OC with an alternative hormonal compound.
  • A second MEDLINE search from January 2000 to July 2010 (MeSH terms: endometriosis, endometrioma, recurrence, OC, laparoscopy) identified three controlled studies on long-term postoperative OC use and endometrioma recurrence.
  • The paper also cites RCTs on postoperative progestin/OC use for symptom recurrence; study quality was not assessed, and no meta-analysis was performed.

Limitations

  • Stated: study quality was not assessed in the MEDLINE search; information on the cost of endometriosis to patients and society is limited.
  • Evident: this is a narrative/opinion review with explicit advocacy for progestins and OCs, without systematic quality appraisal, risk-of-bias assessment, or meta-analysis; conclusions may be influenced by selected citation and interpretation of the literature.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
