Krwawienie poprzymiotopauzalne
Etiologia i przyczyny

Krwawienie poprzymiotopauzalne definiuje się jako krwawienie z pochwy występujące co najmniej rok po ostatniej miesiączce i dotyczy 4-11% kobiet po menopauzie, stanowiąc około 5% wizyt ginekologicznych. Najczęstszą przyczyną (60-80%) jest atrofia narządów płciowych spowodowana niedoborem estrogenów, prowadząca do atrofii pochwy i endometrium, co zwiększa podatność na krwawienia i stany zapalne. Hiperplazja endometrium występuje u 5-10% pacjentek i może mieć charakter prosty lub złożony, z lub bez atypii, z ryzykiem progresji do raka endometrium wynoszącym od 1% do 29%. Polipy endometrium i szyjki macicy odpowiadają za 2-12% przypadków, a nowotwory złośliwe, głównie rak endometrium, stanowią około 10% przyczyn krwawienia. Czynniki ryzyka raka endometrium obejmują m.in. otyłość, cukrzycę typu 2, stosowanie HTZ bez progesteronu, tamoksyfen, zespół Lyncha oraz późną menopauzę.

Przyczyny krwawienia poprzymiotopauzalnego

Krwawienie poprzymiotopauzalne odnosi się do każdego krwawienia z pochwy, które występuje rok lub więcej po ostatniej miesiączce, czyli po zakończeniu menopauzy. Stanowi ono około 5% wszystkich wizyt ginekologicznych i dotyczy około 4-11% kobiet po menopauzie. Chociaż w większości przypadków krwawienie to ma łagodne przyczyny, zawsze wymaga diagnostyki, ponieważ w około 10% przypadków może być wczesnym objawem raka endometrium.123

Atrofia narządów płciowych

Najczęstszą przyczyną krwawienia poprzymiotopauzalnego, odpowiadającą za około 60-80% przypadków, jest atrofia narządów płciowych spowodowana niedoborem estrogenów. W jej wyniku dochodzi do:

  • Atrofii pochwy (atrophic vaginitis) – ścianki pochwy stają się cieńsze, suche i bardziej podatne na stany zapalne, co może prowadzić do krwawienia, szczególnie po stosunku12
  • Atrofii endometrium (endometrial atrophy) – ścieńczenie błony śluzowej macicy prowadzi do zwiększonej podatności na krwawienie i stany zapalne12

Przewlekłe zapalenie endometrium wtórne do atrofii może objawiać się plamienia lub niewielkim krwawieniem. Ten rodzaj krwawienia często ustępuje po zastosowaniu miejscowej terapii estrogenowej.12

Hiperplazja endometrium

Hiperplazja endometrium (rozrost błony śluzowej macicy) występuje u około 5-10% kobiet z krwawieniem poprzymiotopauzalnym. Jest to stan, w którym endometrium ulega nadmiernemu pogrubieniu, co może prowadzić do krwawienia.12 Hiperplazja endometrium może być:

Ryzyko progresji do raka endometrium wynosi odpowiednio 1%, 3%, 8% i 29% dla hiperplazji prostej lub złożonej, bez atypii lub z atypią.1 Główną przyczyną hiperplazji jest nadmierna ekspozycja na estrogeny bez przeciwważnego działania progesteronu, co może wynikać z:12

  • Otyłości
  • Cukrzycy typu 2
  • Zespołu policystycznych jajników
  • Stosowania terapii estrogenowej bez progesteronu
  • Późnej menopauzy

Polipy i mięśniakomacicze

Polipy endometrium i szyjki macicy stanowią przyczynę 2-12% przypadków krwawienia poprzymiotopauzalnego.1 Są to zwykle łagodne zmiany rozrostowe, które mogą powodować nieregularne krwawienia. Ryzyko transformacji nowotworowej polipów jest większe u kobiet po menopauzie niż przed nią.12

Mięśniakomacicze (włókniaki) to łagodne guzy rozwijające się w mięśniówce macicy. Chociaż zwykle zmniejszają się po menopauzie z powodu obniżonego poziomu estrogenów, nadal mogą powodować krwawienie, zwłaszcza jeśli wrastają do błony śluzowej macicy.12

Nowotwory złośliwe

Nowotwory złośliwe stanowią przyczynę około 10% przypadków krwawienia poprzymiotopauzalnego, z czego najczęstszym jest rak endometrium.12 Krwawienie jest najczęstszym objawem raka endometrium i występuje u około 90% kobiet z tym rozpoznaniem.12

Czynniki ryzyka raka endometrium obejmują:12

  • Wczesną pierwszą miesiączkę
  • Późną menopauzę
  • Stosowanie estrogenów bez progestagenów
  • Stosowanie tamoksyfenu
  • Starszy wiek
  • Otyłość
  • Zespół metaboliczny
  • Cukrzycę
  • Zespół policystycznych jajników
  • Niektóre schorzenia dziedziczne (zespół Lyncha, zespół Cowdena)

Inne nowotwory złośliwe, które mogą powodować krwawienie poprzymiotopauzalne, to rak szyjki macicy, rak jajnika, rak pochwy oraz rzadziej rak sromu.12

Przyczyny hormonalne

Terapia hormonalna zastępcza (HTZ) jest częstą przyczyną krwawienia poprzymiotopauzalnego, odpowiadającą za 15-25% przypadków.1 Krwawienie może wystąpić podczas rozpoczynania terapii, zmiany dawkowania lub zaprzestania leczenia.12

Tamoksyfen, lek stosowany w leczeniu raka piersi, może również powodować krwawienie poprzymiotopauzalne ze względu na jego działanie estrogenopodobne na endometrium. Kobiety przyjmujące tamoksyfen są narażone na zwiększone ryzyko rozwoju hiperplazji endometrium i raka endometrium.12

Inne przyczyny

Do innych przyczyn krwawienia poprzymiotopauzalnego należą:12

  • Zakażenia narządów płciowych – zapalenie pochwy, szyjki macicy, endometrium (endometritis), w tym zakażenia przenoszone drogą płciową
  • Urazy mechaniczne – uszkodzenia pochwy podczas stosunku, urazy zewnętrzne
  • Stosowanie leków przeciwkrzepliwych – zwiększających ryzyko krwawienia
  • Zaburzenia krzepnięcia krwi – np. choroba von Willebranda
  • Krwawienie z sąsiednich narządów – np. z dróg moczowych lub odbytnicy
  • Zaburzenia tarczycy
  • Ciała obce w pochwie

Czynniki ryzyka krwawienia poprzymiotopauzalnego

Istnieje kilka czynników, które mogą zwiększać ryzyko wystąpienia krwawienia poprzymiotopauzalnego:12

  • Wiek – częstość krwawienia poprzymiotopauzalnego zmniejsza się wraz z upływem czasu od menopauzy, ale ryzyko, że będzie ono spowodowane rakiem, wzrasta z wiekiem
  • Otyłość – zwiększa ryzyko hiperplazji endometrium i raka endometrium
  • Cukrzyca – szczególnie typu 2, zwiększa ryzyko hiperplazji i raka endometrium
  • Stosowanie hormonalnej terapii zastępczej – zwłaszcza estrogenów bez progesteronu
  • Stosowanie tamoksyfenu – zwiększa ryzyko patologii endometrium
  • Późna menopauza – przedłużona ekspozycja na estrogeny
  • Bezdzietność – zwiększa ryzyko raka endometrium
  • Wywiad rodzinny w kierunku nowotworów ginekologicznych, szczególnie zespołu Lyncha

Znaczenie kliniczne krwawienia poprzymiotopauzalnego

Krwawienie poprzymiotopauzalne, choć zwykle ma łagodną przyczynę, zawsze wymaga dokładnej diagnostyki, ponieważ:12

  • Jest głównym objawem raka endometrium – najczęstszego nowotworu złośliwego układu rozrodczego
  • Około 90% kobiet z rakiem endometrium doświadcza krwawienia jako pierwszego objawu
  • Wczesne wykrycie raka endometrium zwiększa szanse na skuteczne leczenie – przy wczesnym rozpoznaniu 5-letnie przeżycie sięga 95%

Głównym powikłaniem krwawienia poprzymiotopauzalnego jest wtórna niedokrwistość, która występuje u około 10% kobiet.1 Krwawienie może również powodować dyskomfort, niepokój i obniżenie jakości życia.1

Częstość występowania raka endometrium u kobiet z krwawieniem poprzymiotopauzalnym różni się w zależności od regionu geograficznego – od 5% w Ameryce Północnej do 13% w Europie Zachodniej.1 Odsetek ten jest niższy u kobiet stosujących hormonalną terapię zastępczą.1

Atypowe przyczyny krwawienia poprzymiotopauzalnego

Oprócz typowych przyczyn ginekologicznych, krwawienie poprzymiotopauzalne może wynikać z bardziej nietypowych stanów:12

  • Gruźlica endometrium – rzadka przyczyna krwawienia, szczególnie w regionach endemicznych
  • Mięsak macicy – rzadki nowotwór złośliwy miometrium
  • Guzy wydzielające estrogeny – np. nowotwory z komórek ziarnistych jajnika
  • Endometrioza pomenopauzalna – szczególnie u kobiet stosujących HTZ
  • Przerzuty nowotworowe do narządów płciowych – np. z raka jelita grubego, pęcherza moczowego

W rzadkich przypadkach krwawienie poprzymiotopauzalne może być nietypowym objawem innych nowotworów, takich jak chłoniak nieziarniczy czy gruczolakorak trzustki.1

Podsumowanie przyczyn krwawienia poprzymiotopauzalnego

Krwawienie poprzymiotopauzalne może mieć różnorodne przyczyny, które można podsumować następująco:12

Rodzaj przyczyny Konkretne stany Częstość występowania
Atrofia Atrofia pochwy, atrofia endometrium 60-80%
Polipy Polipy endometrium, polipy szyjki macicy 2-12%
Hiperplazja endometrium Bez atypii, z atypią 5-10%
Rak Rak endometrium, szyjki macicy, jajnika, pochwy 5-10%
Hormonalna terapia zastępcza Krwawienie z odstawienia, przełom 15-25%
Inne Zakażenia, urazy, leki, zaburzenia krzepnięcia 5-10%

Należy pamiętać, że krwawienie poprzymiotopauzalne, niezależnie od jego nasilenia czy częstości, zawsze wymaga konsultacji lekarskiej. Wczesna diagnoza i leczenie mogą zapobiec rozwojowi poważnych chorób lub umożliwić ich wczesne wykrycie, co znacznie poprawia rokowanie.12

    https://my.clevelandclinic.org/health/diseases/21549-postmenopausal-bleeding
    Postmenopausal bleeding is vaginal bleeding that occurs a year or more after your last menstrual period. It can be a symptom of vaginal dryness, polyps (noncancerous growths) or other changes in your reproductive system. In about 10% of women, bleeding after menopause is a sign of uterine cancer. […] In most cases, postmenopausal bleeding is due to benign (noncancerous) conditions and isnt a cause for worry. But for about 10% of women, bleeding after menopause is an early sign of uterine cancer (cancer in the lining of your uterus). […] The most common causes of bleeding or spotting after menopause include: Vaginal atrophy (the lining of your vagina becomes thin and dry, which means it bleeds more easily). Hormone replacement therapy (HRT) (changing or stopping HRT can cause bleeding). Uterine cancer (about 90% of people with uterine cancer experienced vaginal bleeding before their diagnosis). Endometrial hyperplasia (the lining of your uterus gets too thick and may contain abnormal cells). Uterine polyps (benign growths in your uterus).

    Vaginal atrophy (thinning of vaginal tissue): Estrogen helps to keep this tissue healthy. After menopause, low estrogen levels can cause your vaginal walls to become thin, dry, and inflamed. That often leads to bleeding after sex. […] Cancer: Bleeding is the most common symptom of endometrial or uterine cancer after menopause. It can also signal vaginal or cervical cancer. […] Sexually transmitted diseases: Some, like chlamydia and gonorrhea, may cause spotting and bleeding after sex. Herpes sores can also bleed. […] Medications: Bleeding is often a side effect of certain drugs, like hormone therapy, tamoxifen, and blood thinners.

    If you have any bleeding — even if it’s only spotting — you should see a doctor. They’ll want to rule out serious causes, like cancer. […] A number of conditions may lead to postmenopausal bleeding: […] Polyps: These tissue growths show up inside your uterus or cervical canal, or on your cervix. They’re usually not cancer, but they can cause spotting, heavy bleeding, or bleeding after sex. […] Endometrial atrophy (thinning of the uterine lining): The endometrium is the tissue that lines your uterus. It responds to hormones like estrogen and progesterone. Low hormone levels after menopause can cause it to get too thin. This may trigger bleeding. […] Endometrial hyperplasia (thickening of the uterine lining): After menopause, you may have too much estrogen and too little progesterone. As a result, the endometrium gets thicker and can bleed. Sometimes cells in the endometrium can become abnormal. This could lead to cancer, so get it treated as soon as possible.

    Bleeding sometimes, but not always, suggests endometrial cancer. […] While postmenopausal bleeding often stems from benign (noncancerous) conditions, it can be the first sign of endometrial (uterine) cancer. […] Common causes include: Polyps are outgrowths of the inner lining of the uterus. They are usually benign; however, in postmenopausal people, there is a higher risk for cancerous uterine polyps compared to premenopausal people. […] The most serious cause of postmenopausal bleeding is endometrial cancer, the fourth most common cancer in females in the United States. […] With endometrial cancer, cells within the inner lining of the uterus grow abnormally and uncontrollably.

After a year has passed without menstrual periods, any vaginal bleeding that that occurs is known as postmenopausal bleeding, and it is considered abnormal. […] There are several possible causes of postmenopausal bleeding, most of which are not worrisome. However, between 10% and 15% women who experience postmenopausal bleeding may have endometrial cancer. […] Postmenopausal bleeding refers to any vaginal bleeding that occurs in a menopausal woman. Because all postmenopausal bleeding is considered abnormal, its important to contact your provider if this occurs.

  • #1 Postmenopausal Bleeding (PMB) | Doctor
    https://patient.info/doctor/postmenopausal-bleeding
    Postmenopausal bleeding (PMB) is defined for practical purposes as vaginal bleeding occurring after twelve months of amenorrhoea, in a woman of the age where the menopause can be expected. […] Although PMB usually has a benign cause, the priority is to exclude malignancy. […] PMB is a common problem representing 5% of all gynaecology outpatient attendances. These are most commonly to eliminate endometrial cancer as the cause of the bleed. […] Causes of PMB (aetiology) include vaginal atrophy, use of HRT, endometrial hyperplasia; simple, complex, and atypical, endometrial cancer, endometrial polyps or cervical polyps, cervical cancer, uterine sarcoma (rare), ovarian cancer, especially oestrogen-secreting (theca cell) ovarian tumours, vaginal cancer (very uncommon), vulval cancer may bleed, but the lesion should be obvious, and non-gynaecological causes including trauma or a bleeding disorder. […] Most women with PMB will not have significant pathology but the dictum remains that postmenopausal bleeding is cancer until proved otherwise. […] Women with breast cancer who take tamoxifen on a long-term basis are at increased risk of endometrial cancer.

    Overall, the analysis showed that, consistent with what had been seen in earlier studies, 90% of women diagnosed with endometrial cancer had experienced postmenopausal bleeding. […] The number of women with postmenopausal bleeding who were diagnosed with endometrial cancer varied around the globe. While the rate was 9% overall, it ranged from 5% in North America to 13% in Western Europe. […] Among the studies included in the analysis, the risk of endometrial cancer in women with postmenopausal bleeding was lower in studies that included women using hormone replacement therapy. […] It’s only if there’s persistent bleeding after the initial 6 months of [hormone replacement] that it may be more concerning and should trigger testing for endometrial cancer. […] The findings confirm that „postmenopausal women with [vaginal] bleeding have a low risk of endometrial cancer, but the vast majority of women with endometrial cancer present with bleeding. […] women should know that getting tested if they have postmenopausal bleeding „gives us an opportunity to [potentially] detect endometrial cancer early, which provides a high likelihood of cure.
  • #1 Postmenopausal Vaginal Bleeding
    https://www.uspharmacist.com/article/postmenopausal-vaginal-bleeding
    Although relatively common, vaginal bleeding is considered abnormal when reported in a woman who has passed the onset of menopause. In approximately 20% to 30% of cases of postmenopausal vaginal bleeding, the cause may be attributed to endometrial cancer or atypical endometrial hyperplasia. Additional causes include estrogen or progesterone therapy (i.e., hormone replacement therapy [HRT]) and genital atrophy due to low estrogen levels. […] Although postmenopausal vaginal bleeding remains a cardinal symptom of endometrial cancer, case reports have shown it may be an unusual presenting sign of other diseases as well, including non-Hodgkin lymphoma and pancreatic adenocarcinoma. […] When unexplained vaginal bleeding occurs, malignancy should be ruled out; persistent postmenopausal vaginal bleeding should be investigated aggressively.

    Postmenopausal bleeding (PMB) accounts for five per cent of office gynaecology presentations. Its definition is self-explanatory, as any bleeding from the genital tract occurring in the postmenopausal period, arising after 12 months of amenorrhoea in a women of menopausal age. Generally, four to 11 per cent of postmenopausal women will experience bleeding. The chance of this occurring reduces as time since menopause increases. […] While the most common cause for PMB is atrophy, the diagnostic algorithm for PMB is designed to detect cancer, particularly endometrial cancer. Vaginal, endometrial and urogenital atrophy is par for the course with postmenopausal hypoestrogenism. Atrophy accounts for 60-80 per cent of all causes of PMB, while endometrial hyperplasia and cancer each account for ten per cent of cases.

    During menopause, when your vagina and uterus walls thin as a result of a decrease in oestrogen hormone, they become fragile. This causes dryness, irritation, and discomfort down there, especially during sex. You may notice spots after sex, or sometimes without sex, when the atrophy gets severe. […] Any infection in your reproductive or urinary systems can cause postmenopausal bleeding. Infections like tuberculosis of the uterus wall, vaginal or cervix swelling, and bladder infections can hurt and irritate the tissues that lead to bleeding. […] Endometrial hyperplasia is the abnormal growth of cells that make up your uterus wall. The uterus wall gets thicker and causes bleeding from the vagina. It is not considered cancer, but if not treated promptly, it may lead to cancer. This abnormal growth may result from hormonal imbalances like oestrogen and progesterone.
