Is adolescence a crucial period for endometriosis patients?

Leuven University: founded 1425; 2000 beds

Learning objectives

1.  Prevalence of endometriosis in adolescents 2.  Prevalence of menstrual cycle related pain

problems in adolescents 3.  Early detection: how can we improve timely referral

to endo centers of expertise for adolescents with menstrual cycle related pain problems, resistant to medical management?

4.  Can early treatment of adolescent endo prevent adult endometriosis?

•  Definition Gynecologic disorder Endometrial-like tissue Outside the uterus (ectopic) Chronic inflammatory reaction Women of reproductive age

•  Localization

Pelvis Peritoneum Pelvic organs

•  Endo Classification (rAFS, 1997)

Minimal rAFS I

Mild rAFS II peritoneal / ovarian involvement Moderate rAFS III adnexal / cul-de-sac adhesions Severe rAFS IV

•  Endo Phenotypes (often co-exist) -Peritoneal -Ovarian Endometrioma -Deeply Infiltrative endometriosis with extension to colorectum, bladder and ureter

Learning objectives



to endo centers of expertise for adolescents with menstrual cycle related pain problems, resistant to medical management to endometriosis.

4.  Early treatment of adolescent endo: prevention of adult endometriosis?

Symptoms of adolescent endometriosis (Laufer et al, 1997; Borach et al, 2009; Giudice et al, 2011)

•  Pelvic Pain: cyclic or acyclic or combined •  Pelvic Pain can be unpredictable, intermittent

o continuous throughout menstrual cycle •  Pelvic Pain can be dull/throbbing or sharp,

possibly worse by physical activity •  Laparoscopic presentation: traditionally

believed to be mostly peritoneal and subtle lesions

Systematic Review: Prevalence of endometriosis diagnosed by laparoscopy in adolescents Systematic literature search (1980-2012) in PUBMED and EMBASE key words

“endometriosis”, “laparoscopy”, “adolescents” and “chronic pelvic pain (CPP)”

Prevalence of menstrual cycle related pain in 12-year old girls in Flanders, Belgium JOnG! – Policy Research Center of Welfare, Public Health & Family

Large population-based study on characteristics of menstrual cycle and related complaints in young teenage girls at or shortly after menarche. METHODS: Part of larger multidisciplinary cohort study in Flanders,

Belgium; n=792 (age 12.8 ± 0.3 yrs); semi-structured Qaire. RESULTS: Out of 363 girls (47.2%) who had reached menarche: 42% (95%CI: 36 – 47%) reported painful menstruations!

Prevalence of menstrual cycle related pain in 12-year old girls in Flanders, Belgium JOnG! – Policy Research Center of Welfare, Public Health & Family

RESULTS: -  Likelihood of dysmenorhea decreased approximately 50% for every

year that age at menarche increased (OR: 0.5; 0.3 - 0.7; p < 0,001).

-  Painful menstruation: positively correlated with duration of menstrual flow and amount of blood loss.

-  Negative impact of menstruation on social activities: 25%, but

higher (41%) in girls with painful menstruation than in girls without painful menstruation (14%, p < 0.001).

Factors associated with development of adult endo (Treloar et al, 2010; Chapron et al, 2011)

•  Reduced risk: menarche >= 14 years (Treloar et al, 2010) •  Increased risk for endo vs non-endo (Treloar et al, 2010):

Frequent occurrence early dysmen. (OR 2.6, CI 1.1-6.2) •  Increased risk DIE versus non DIE (Chapron et al, 2011)

-Positive Family History of endometriosis (OR 3.2; CI 1.2-8.8)

- Increased frequency (OR 4.5; CI 1.9-10.4) and duration (8 +/- 5 versus 5 +/- 4 yrs) of COC use for

severe primary dysmenorrhea - Increased frequency of school absenteism during

menstruation (OR 1.7; CI 1-3)

Development of questionnaire for detection of significant (non)menstrual pain in adolescent girls at risk for endometriosis •  SR to identify questionnaires measuring QOL in women and

girls with endo and CPP !selection of 3 questionnaires with highest relevance: EHP 30 Jones et al, 2001; Nnoaham et al, 2009; Parker et al, 2010)

•  Analysis of 3 other existing questionnaires previously developed within Leuven University (Hospitals)

•  Comparison of the 6 selected questionnaires (3 international, 3 national)

•  Development of a new questionnaire (in progress)

Development of questionnaire for detection of significant (non)menstrual pain in adolescent girls at risk for endometriosis

Next steps in development of a new screening questionnaire

as a case finding instrument for adolescents and young adults at risk of endometriosis

1/ validation 2/ integration into routine developmental surveillance practices of health-care workers who take care of adolescent girls 3/ establishment of clinical pathways for referral to endo centers of expertise (D’Hooghe and Hummelshoj, 2006)

Communicating endometriosis with young women to decrease diagnosis time (Shadbolt et al, Health Promot J Austr 2013)

Research Question: What do women know/want to know about endometriosis and how is this best communicated? •  Online survey for women aged 16-25 yrs (n=131) -52% had heard about endometriosis (but often vague/wrong) -89% thought female teenagers should be educated about it -78% thought young men should be educated about it •  Sources of information: - schools (40%), internet (13%), magazines (13%) - talking to doctor (75%), parent (59%) or friend (51%)

Learning objectives



to endo centers of expertise for adolescents with menstrual cycle related pain problems, resistant to medical management to endometriosis.


TREATMENT OF ENDOMETRIOSIS-ASSOCIATED PAIN

Recommendations

Empirical treatment

Applied to adolescents with presumed endometriosis: INDIVIDUALIZE -  Pain killers: paracetamol, NSAIDs -  Cyclical combined hormonal contraceptives ! semicontinuous

during 2, 3 consecutive months ! continuous use -  Progestins: little data in adolescents

Are hormonal therapies effective for painful symptoms associated with endometriosis?

Are hormonal therapies effective for painful symptoms associated with endometriosis? Hormonal contraceptives

Are hormonal therapies effective for painful symptoms associated with endometriosis? Progestagens and anti-progestagens

LNG IUD use in adolescents (Yoost et al, 2013)

•  Retrospect., n=18, 14-22 yrs •  IUD placed at time of

diagnostic laparoscopy (n=8) or after surgery + hormonal therapy (mostly GnRHa, n=10)

•  Result: pain improvement within 4-5/12 after placement of LNG-IUD, BUT 67% required additional hormonal therapy for suppression of pain and pelvic bleeding

Are hormonal therapies effective for painful symptoms associated with endometriosis? GnRH agonists

Are hormonal therapies effective for painful symptoms associated with endometriosis? Aromatase inhibitors

Are analgesics effective for symptomatic relief of pain associated with endometriosis?

Is surgery effective for painful symptoms associated with endometriosis?

Is surgery effective for painful symptoms associated with endometriosis? Ablation versus excision of endometriosis


Surgical interruption of pelvic nerve pathways


Pain associated with ovarian endometrioma


Pain associated with deep endometriosis

Is untreated endometriosis progressive in adolescents?

•  6/12 (Thomas and Cooke, 1987): 47% deterioration (adults)

•  12/12 (Mahmood and Templeton, 1990): 73% progression/status quo (adults)

(64% progression, 9% status quo) •  Beyond 12/12: limited data

AJOG, 1993: progression at 0.3 AFS points per month

BABOON MODEL FOR ENDOMETRIOSIS •  Spontaneous endometriosis is a progressive

disease when followed by laparoscopies every 6 months during 2 years (D’Hooghe et al, 1996b)

•  Baboons with an initially normal pelvis develop in 64% histologically proven minimal endometriosis after 32 months as assessed by laparoscopies every 6 months

(D’Hooghe et al, 1996c) •  Increased duration of captivity --> increased

prevalence of endometriosis (D’Hooghe et al, 1996a)

Surgery useful in adolescents? We do not know!

•  Only retro- (n=3) or prospective (n=1) case series •  NO case control/contr.cohort/randomized studies •  Effect surgery: some improvement, but often

recurrence/persistence of pain and about 50% require repeat surgery(Yeung et al, 2011)

•  Postoperative hormonal suppression: –  If not: progression reported (3 cases; Unger, 2011) –  If treated: persistence/recurrence of pain (Doyle, 2009) and

significant side effects (Kaser et al, 2012) leading to compliance problems (Unger, 2011)

Endo progression in non-medically managed adolescents (Unger and Laufer, JPAG, 2011)

•  Retrospective case series (n=3, 13-16 yrs) •  Presenting symptom: pelvic pain resistant to continuous (n=2)

or cyclic (n=1) COC and painkillers •  Diagnostic/operative laparoscopy: minimal endo (ASRM,

1997) •  Postoperative hormonal suppression therapy:

noncompliance due to side effects (depression, irregular bleeding, fatigue)

•  Repeat laparoscopy for recurrence AND worsening of pelvic pain: progression to severe (n=2) or mild (n=1) endo, with DIE (n=1), endometrioma (n=1), diaphragmatic endo (n=1)

Combined Surgical-Medical Intervention retards disease progression in adolescents receiving hormonal suppression (Doyle et al, JPAG, 2009) BUT MAY NOT IMPROVE PAIN

•  Retrospective case series (n=90, median 7 (12-24) yrs at initial lap)

•  Inclusion criterium: pain exacerbation after Lap 1 during hormonal suppression requiring Lap 2

•  Operative Laparoscopy 1 (for pelvic pain resistant to hormonal suppression and NSAIDs):

Median Minimal Endo (Range Minimal-Moderate Endo)

Combined Surgical-Medical Intervention retards disease progression in adolescents receiving hormonal suppression (Doyle et al, JPAG, 2009) BUT MAY NOT IMPROVE PAIN

•  Postoperative hormonal suppression in all patients (91% continuous COC, 78% GnRHa + add-back, 12% POP)

•  Lap 2 (n=90, median 29/12 after Lap 1): Endo stage: no change (70%), improvement (19%),worsening (10%)

•  Lap 3 (n=33, median 27/12 after Lap 2): Endo stage: no change (70%), improvement (3%) or worsening (9%)

Postop Norethindrone Acetate (5-15 mg) may be useful for young women resistant to other medical treatment (Kaser et al, JPAG, 2012) BUT SEs •  Retrospective case series (n=194, median 19 years,

minimal-mild endo, only pts treated with NA alone postoperatively)

•  Indication for postop NA: persistent pain or bleeding on COC (57%), or GnRHa +NA (9%), or CI for E2 use (27%)

•  Significant improvement in pain scores for all patients except those previously prescribed GnRHa + addback

•  Significant improvement in bleeding scores for all patients

•  ! 45% significant side effects: weight gain (46%), acne (10%), mood lability (9%), vasomotor instability (8%)

Effect of complete laparoscopic excision of endo in teenagers (Yeung et al, FS, 2011): ABOUT HALF REPEAT SURGERY WITHIN 23 MONTHS •  Prospective case series of teenagers (n=17, 12-19 yrs) with

laparoscopically and histologically confirmed endometriosis •  Operative Laparoscopy (pain suspicious for endo):

minimal (29%), mild (65%) or moderate (6%) endo •  Outcome measure: Rate of recurrent/persistent endometriosis after

complete laparoscopic excision •  Follow-up (median 23/12): only 1/3 (7/17) postop temporary hormonal

suppression at own initiative (no subanalysis) •  Pre-post comparison: improvement for dysmenorrhea, dyschezia,

painful bladder, QOL, … but not for CPP or dyspareunia •  47% repeat surgery for persistent or recurrent pain: NO ENDO, half

pelvic adhesions, half resection abnl peritoneum (Endo neg.)

FIRST: WELL DESIGNED PROSPECT. CASE SERIES Clinical outcome assessment of adolescent endometriosis

Electronic file + Questionnaire (before/after design)

prospective: 1 month preoperative 6 / 12 / 18 / 24 months postoperative

•  Postoperative complications:

•  Pain: patient centered VAS: dysmenorrhea, deep dyspareunia, Nonmenstrual pain

•  Quality of life: patient centered EHP30 (Jones, 2001)

•  Reintervention Recurrence: Histological confirmation!

•  Future Fertility outcome: Life table analysis

Conclusions

1.  Prevalence of endometriosis in adolescents with pelvic pain resistant to COCs/painkillers: 62% (1/3 with moderate-severe endo!)

2.  Prevalence of dysmenorrhea in adolescents:

- 42% (13 yrs), 40% (15-17 yrs), 52% (18-19yrs) - associated with reduced QOL (40% 13yr olds) - resistant to COCs or NSAIDs: 4-5%

Conclusions

3.  Early detection: validated questionnaire needed for primary health care professionals/ school doctors to improve timely referral of adolescents with menstrual cycle related pain problems, resistant to medical management to endometriosis, to endo centers of expertise.

Conclusions

4.  Can early treatment of adolescent endo prevent adult endometriosis? Unknown, No valid research. Complex: pt compliance (SE medication)? pain recurrence = not always endo recurrence? Start with well designed prospective case series with predefined PRO !controlled cohort studies !RCTs
