Galaktocele lub laktoreja
Epidemiologia
Galaktocele, definiowane jako nieprawidłowe wydzielanie mleka u osób niebędących w ciąży ani niekarmiących, dotyczy około 20-25% kobiet w ciągu życia i jest trzecią najczęstszą dolegliwością piersi. Główną przyczyną jest hiperprolaktynemia, występująca u 0,4% populacji dorosłych, ale znacznie częstsza w grupach ryzyka, takich jak kobiety z zaburzeniami miesiączkowania (9%), zespołem policystycznych jajników (17%) czy pacjentki klinik planowania rodziny (5%). U około 75% pacjentek z galaktocele i brakiem miesiączki stwierdza się hiperprolaktynemię, z czego 30% przypadków jest spowodowanych prolaktynowymi gruczolakami przysadki. Poziomy prolaktyny powyżej 200 ng/ml są typowe dla makrogruczolaków, które występują u 35-50/100 000 osób, głównie kobiet w wieku 20-50 lat. Leki przeciwpsychotyczne i doustne środki antykoncepcyjne również zwiększają ryzyko galaktocele, szczególnie w dawkach wyższych lub starszych preparatach estrogenowych.

Galaktocele lub laktoreja – Epidemiologia i nadzór
Galaktocele (laktoreja) to nieprawidłowe wydzielanie mleka z piersi u osób niebędących w ciąży ani niekarmiących piersią. Jest to stosunkowo częsty problem kliniczny, którego występowanie różni się w zależności od badanej populacji oraz przyjętych kryteriów diagnostycznych.12
Rozpowszechnienie w populacji ogólnej
Dokładna częstość występowania galaktocele w populacji ogólnej nie jest precyzyjnie ustalona, jednak według dostępnych danych dotyczy ona około 20-25% kobiet w ciągu życia.123 Niektóre źródła wskazują, że galaktocele jest trzecią najczęstszą dolegliwością piersi u kobiet.4
Występowanie hiperprolaktynemii, która często jest przyczyną galaktocele, szacuje się na około 0,4% w nieselekcjonowanej populacji osób dorosłych, ale odsetek ten znacznie wzrasta w określonych grupach pacjentów.56
Częstotliwość występowania w grupach ryzyka
Hiperprolaktynemia, będąca główną przyczyną galaktocele, występuje zdecydowanie częściej w określonych populacjach:7
- U 5% pacjentek z klinik planowania rodziny89
- U 9% kobiet z zaburzeniami miesiączkowania1011
- U 9-17% kobiet z zaburzeniami reprodukcyjnymi12
- U 17% kobiet z zespołem policystycznych jajników1314
Około 75% pacjentek z galaktocele i towarzyszącym brakiem miesiączki wykazuje hiperprolaktynemię, z czego około 30% przypadków spowodowanych jest przez guzy wydzielające prolaktynę.1516
Różnice demograficzne
Galaktocele występuje znacznie częściej u kobiet niż u mężczyzn, choć może dotyczyć obu płci.1718 Najbardziej narażone są kobiety w wieku reprodukcyjnym (15-50 lat), ze szczególnym nasileniem w przedziale wiekowym 20-35 lat.192021
Badania wskazują, że hiperprolaktynemia występuje 3,5 razy częściej u kobiet niż u mężczyzn, z roczną zapadalnością na poziomie 13,8 przypadków na 100 000 osobolat.22
Galaktocele wywołana lekami
Szczególną grupę stanowią pacjenci przyjmujący leki mogące indukować hiperprolaktynemię i w konsekwencji galaktocele. Program nadzoru farmakologicznego AMSP (Arzneimittelsicherheit in der Psychiatrie) prowadzony w krajach niemieckojęzycznych w latach 1993-2015 wykazał:2324
- Częstość występowania galaktocele wywołanej lekami przeciwpsychotycznymi wynosiła 0,97 przypadków na 1000 hospitalizowanych pacjentek2526
- Najwyższą częstość odnotowano u pacjentek w wieku 16-30 lat (3,81 przypadków na 1000 hospitalizowanych)27
- Wyższe dawki leków przeciwpsychotycznych korelowały z wyższym odsetkiem występowania galaktocele28
W przypadku doustnych środków antykoncepcyjnych, według starszych badań z lat 80., galaktocele występowała u 10-19% kobiet stosujących antykoncepcję hormonalną, przy czym do 30% doświadczało hiperprolaktynemii. Nowsze preparaty o niższych dawkach estrogenów wiążą się z rzadszym występowaniem tego powikłania.29
Galaktocele związana z guzami przysadki
Występowanie gruczolaków wydzielających prolaktynę (prolaktynoma) szacuje się na 35-50 przypadków na 100 000 osób.30 Są one częstsze u kobiet niż mężczyzn (stosunek 10:1), głównie w wieku 20-50 lat.31
Galaktocele występuje u około 80% kobiet z prolaktynoma.32 Poziom prolaktyny często koreluje z wielkością guza, przy czym makrogruczolaki zwykle powodują stężenia powyżej 200 ng/ml.33
Nadzór nad galaktocele
Nadzór nad pacjentami z galaktocele powinien uwzględniać następujące aspekty:3435
- Badania obrazowe (tomografia komputerowa lub rezonans magnetyczny) są zalecane przy utrzymujących się podwyższonych poziomach prolaktyny36
- Niektórzy endokrynolodzy zalecają wykonanie badań obrazowych przy poziomach prolaktyny powyżej 50 ng/ml, inni przy poziomach powyżej 100 ng/ml37
- Pacjenci bez radiograficznych dowodów guza przysadki powinni być kontrolowani raz w roku38
- Pacjenci z makrogruczolakami wymagają dożywotniej terapii supresyjnej za pomocą agonistów dopaminy39
Czynniki ryzyka i śmiertelność
Do głównych czynników ryzyka galaktocele należą:40
- Płeć żeńska
- Wiek reprodukcyjny (20-35 lat)
- Przebyte ciąże
- Stosowanie leków wpływających na poziom prolaktyny
- Schorzenia wpływające na przysadkę mózgową
- Nadmierna stymulacja piersi
- Przewlekły stres
Chociaż sama galaktocele rzadko prowadzi do śmiertelności, badanie przeprowadzone przez Soto-Pedre i wsp. wykazało, że śmiertelność może różnić się w zależności od przyczyny hiperprolaktynemii:41
- Nie stwierdzono zwiększonego ryzyka śmiertelności u pacjentów z mikrogruczolakami przysadki
- Wyższe ryzyko zgonu odnotowano u pacjentów z makrogruczolakami przysadki
- Podwyższone ryzyko śmiertelności występowało również w przypadku hiperprolaktynemii wywołanej lekami oraz idiopatycznej hiperprolaktynemii
Badanie to wykazało również, że hiperprolaktynemia wywołana lekami wiązała się z większym ryzykiem cukrzycy, chorób układu sercowo-naczyniowego, chorób zakaźnych i złamań kości.42
Umiarkowane konsekwencje długotrwałej galaktocele
Długotrwała nieleczona hiperprolaktynemia i galaktocele mogą prowadzić do poważnych konsekwencji zdrowotnych, w tym:4344
- Osteopenii i osteoporozy (szczególnie u pacjentek z towarzyszącym brakiem miesiączki)
- Potencjalnie zwiększonego ryzyka raka piersi u kobiet (choć związek ten wymaga dalszych badań)
- Zaburzeń płodności
- Obniżonego libido u kobiet
- Zaburzeń erekcji i hipogonadyzmu u mężczyzn
Monitorowanie i odpowiednie leczenie pacjentów z galaktocele ma zatem kluczowe znaczenie dla zapobiegania długoterminowym powikłaniom.45
Wnioski i zalecenia dotyczące nadzoru
Biorąc pod uwagę epidemiologię galaktocele, zaleca się:464748
- Systematyczne badania przesiewowe u pacjentek z zaburzeniami miesiączkowania, niepłodnością oraz zespołem policystycznych jajników
- Uważne monitorowanie pacjentów stosujących leki mogące wywoływać hiperprolaktynemię
- Regularne oznaczanie poziomu prolaktyny u pacjentów z galaktocele
- Przeprowadzanie badań obrazowych przysadki u pacjentów z utrzymującą się hiperprolaktynemią
- Długoterminową obserwację pacjentów z rozpoznanym gruczolakiem przysadki
- Interdyscyplinarne podejście do leczenia z udziałem radiologów, endokrynologów, neurochirurgów, neurologów i lekarzy internistów49
Galaktocele, choć często jest łagodnym schorzeniem, może być objawem poważniejszych zaburzeń wymagających dokładnej diagnostyki i długoterminowego nadzoru medycznego.50

This condition occurs in less than 1% of the general population and in 5-14% of patients presenting with secondary amenorrhea. Approximately 75% of patients presenting with galactorrhea and amenorrhea have hyperprolactinemia. Of these patients, approximately 30% have prolactin-secreting tumors. […] Mortality is unlikely, although a study by Soto-Pedre et al did report increased mortality depending on the cause of hyperprolactinemia. In cases where the condition is due to a large prolactin-secreting tumor, local mass effect can lead to significant morbidity. […] The aforementioned study by Soto-Pedre et al found that morbidity and mortality in hyperprolactinemia appears to differ according to the conditions etiology. The investigators reported no link between pituitary tumor-associated hyperprolactinemia and increased morbidity. In contrast, drug-induced hyperprolactinemia was found to be associated with a greater risk of diabetes, cardiovascular disease, infectious disease, and bone fracture. Moreover, the study found no increased mortality risk in hyperprolactinemia patients with pituitary microadenomas, while a greater risk of death was reported in subjects with pituitary macroadenoma or drug-induced hyperprolactinemia, as well as in patients with idiopathic hyperprolactinemia. However, the investigators stated that the morbidity and mortality increases observed in the study did not appear to be directly caused by the serum prolactin elevations themselves and that hyperprolactinemia could perhaps serve as a biomarker for greater morbidity risk.

[…] Data on APD utilization and reports of galactorrhea caused by APDs were analyzed using data from an observational pharmacovigilance program in German-speaking countries-Arzneimittelsicherheit in der Psychiatrie (AMSP)-from 1993 to 2015. 320,383 patients (175,884 female inpatients) under surveillance were treated with APDs for schizophrenia and other indications. […] A total of 170 events of galactorrhea caused by APDs were identified (0.97 cases in 1000 female inpatient admissions). […] Most cases occurred during the reproductive age with the highest incidence among patients between 16 and 30 years (3.81 cases in 1000 inpatients). […] High dosages of the imputed APDs correlated with higher rates of galactorrhea. […] Galactorrhea is a severe and underestimated condition in psychopharmacology.
- #29 Hyperprolactinaemia and galactorrhoea with combined oral contraceptive pill use: A refresherhttps://www1.racgp.org.au/ajgp/2022/june/hyperprolactinaemia-and-galactorrhoea
Galactorrhoea is a milk-like discharge from the nipples when the patient is neither pregnant nor breastfeeding. It happens when abnormally high levels of serum prolactin stimulate the lactotroph cells in the mammillary glands of the breast, resulting in galactorrhoea. Prolactin secretion is regulated by stimulatory or inhibitory hormones produced in the hypothalamus. Physiological causes include pregnancy, stress and nipple stimulation. Pathological causes of hyperprolactinaemia are due to anti-dopaminergic medications, such as antipsychotics. In the absence of these medications, pituitary tumours account for approximately 50% of hyperprolactinaemia cases. Additionally, subclinical hypothyroidism has been found to be associated with hyperprolactinaemia. […] […] The incidence of COCP-associated galactorrhoea is unclear due to lack of recent data on newer agents. Literature from the 1980s suggest that 10-19% of women on a COCP experience galactorrhoea, with up to 30% experiencing hyperprolactinaemia. Some studies have found that COCPs use can increase serum prolactin levels, whereas other studies do not show any effect on prolactin levels. Galactorrhoea is usually seen in COCPs containing high oestrogen doses (35 g), and is most apparent in the week of the placebo pills. In recent newer contraceptives with lower oestrogen doses, this is rarely observed. The proposed mechanism is the stimulatory effect of oestrogen and progesterone on prolactin secretion and the oestrogen-induced proliferation of lactotroph in the anterior pituitary gland. […]

The prevalence of prolactinomas is reported to be between 35 to 50 per 100,000. They are most commonly seen in women (10:1 ratio female/male) and the usual age range is between 20 to 50 years of age. […] Fortunately, only a minority of microadenomas will continue to grow (< 10%) but early detection, monitoring and a management plan, which may be multidisciplinary, is required for good outcomes. Consider accessing expertise in endocrinology and radiology to ensure correct differential between prolactinoma and non-secreting pituitary adenoma as treatment for the latter is usually surgical, not medical.

Galactorrhea occurs in up to 80% of women with prolactinomas. […] Prolactin levels often correlate with the size of the tumor. […] A random prolactin level of more than 100 ng/mL is consistent with a prolactinoma; macroadenomas often produce levels of more than 200 ng/mL. […] Although this patient’s prolactin level is less than 100 ng/mL, it is still significantly above normal. Together with negative results on the rest of her endocrine workup, it is sufficient to diagnose prolactinoma. […] The goals of treatment are: To lower prolactin levels. To decrease tumor size. To reduce galactorrhea. To restore menses and fertility. […] Regardless of their size, prolactinomas are initially treated with dopamine agonists, such as bromocriptine or cabergoline. […] Common adverse effects of both dopamine agonists include nausea and postural hypotension.

Considerable difference of opinion exists as to when radiographic surveillance should be instituted. Many reproductive endocrinologists believe that a CT or MRI scan should be performed in patients with prolactin levels of 100 ng/mL or greater. Most reproductive endocrinologists would institute radiographic surveillance at levels of 50 ng/mL. However, we recommend that radiographic surveillance be undertaken if a persistent hyperprolactinemia is demonstrated at any level. […] Both CT and MRI scans are adequate for the diagnosis of both microadenomas and macroadenomas. Both of these radiographic techniques can detect a pituitary tumor as small as 2 mm.

Galactorrhea Last Updated on May 15, 2024 Overview Galactorrhea (guh-lack-toe-REE-uh) is a milky nipple discharge unrelated to the usual milk production of breastfeeding. Galactorrhea itself isn’t a disease, but it could be a sign of another medical condition. It usually happens in women, even those who have never had children or who have gone through menopause. But galactorrhea can happen in men and babies. […] Excessive breast stimulation, medicine side effects or conditions of the pituitary gland all may contribute to galactorrhea. Often, galactorrhea results from increased levels of prolactin, the hormone that stimulates milk production. […] Risk factors Anything that triggers the release of the hormone prolactin can increase the risk of galactorrhea. Risk factors include: Certain medicines, illicit drugs and herbal supplements. Conditions that affect the pituitary gland, such as noncancerous pituitary tumors. Certain medical conditions, such as chronic kidney disease, spinal cord injury, injuries to the chest wall and underactive thyroid. A lot of touching and rubbing of the breasts. Stress.

This condition occurs in less than 1% of the general population and in 5-14% of patients presenting with secondary amenorrhea. Approximately 75% of patients presenting with galactorrhea and amenorrhea have hyperprolactinemia. Of these patients, approximately 30% have prolactin-secreting tumors. […] Mortality is unlikely, although a study by Soto-Pedre et al did report increased mortality depending on the cause of hyperprolactinemia. In cases where the condition is due to a large prolactin-secreting tumor, local mass effect can lead to significant morbidity. […] The aforementioned study by Soto-Pedre et al found that morbidity and mortality in hyperprolactinemia appears to differ according to the conditions etiology. The investigators reported no link between pituitary tumor-associated hyperprolactinemia and increased morbidity. In contrast, drug-induced hyperprolactinemia was found to be associated with a greater risk of diabetes, cardiovascular disease, infectious disease, and bone fracture. Moreover, the study found no increased mortality risk in hyperprolactinemia patients with pituitary microadenomas, while a greater risk of death was reported in subjects with pituitary macroadenoma or drug-induced hyperprolactinemia, as well as in patients with idiopathic hyperprolactinemia. However, the investigators stated that the morbidity and mortality increases observed in the study did not appear to be directly caused by the serum prolactin elevations themselves and that hyperprolactinemia could perhaps serve as a biomarker for greater morbidity risk.

The widespread use of the selective serotonin reuptake inhibitors (SSRIs) has been accompanied by numerous reports describing a potential association with hyperprolactinemia. […] A growing number of case reports and small studies have described PRL abnormalities and/or manifestations such as galactorrhea, amenorrhea, and breast tenderness in association with the use of SSRIs in women. […] Possible long-term clinical consequences of hyperprolactinemia, including decreased bone density and a potential increased risk of breast cancer, are only beginning to be investigated. […] The classic manifestations of hyperprolactinemia are galactorrhea, amenorrhea, infertility, and decreased libido in women, and erectile dysfunction, hypogonadism, and infertility in males. […] Long-term clinical consequences of hyperprolactinemia are less obvious, and include osteopenia in men and women and the possibility of an increased risk of breast cancer in women.

The diagnosis of pituitary tumor rests essentially on the results of the serum prolactin determination and on radiographic evidence. […] In most cases the galactorrhea does not require treatment for its own sake. […] If amenorrhea accompanies hyperprolactinemia, as is often the case, then patients are at increased risk for development of osteoporosis. […] The dopamine agonists such as bromocriptine are more effective than other forms of treatment in lowering serum prolactin, stopping galactorrhea, and restoring ovulatory menses in patients with hyperprolactinemia.

Galactorrhea is commonly caused by hyperprolactinemia, especially when it is associated with amenorrhea. Hyperprolactinemia is most often induced by medication or associated with pituitary adenomas or other sellar or suprasellar lesions. […] After pathologic nipple discharge is ruled out, patients with galactorrhea should be evaluated by measurement of their prolactin level. Those with hyperprolactinemia should have pregnancy ruled out, and thyroid and renal function assessed. Brain magnetic resonance imaging should be performed if no other cause of hyperprolactinemia is found. […] Patients with prolactinomas are usually treated with dopamine agonists (bromocriptine or cabergoline); surgery or radiation therapy is rarely required. Medications causing hyperprolactinemia should be discontinued or replaced with a medication from a similar class with lower potential for causing hyperprolactinemia. Normoprolactinemic patients with idiopathic, nonbothersome galactorrhea can be reassured and do not need treatment; however, those with bothersome galactorrhea usually respond to a short course of a low-dose dopamine agonist.

Hypothyroidism, characterized by an underactive thyroid gland, hampers hormonal dynamics. […] Chronic stress may elevate prolactin levels, adding to the manifestation of galactorrhea. […] Galactorrhea can be managed and possibly prevented by taking proactive steps to maintain hormonal equilibrium. […] The galactorrhea diagnosis involves a thorough medical history, physical examination, hormonal testing (particularly prolactin levels), and possibly imaging studies like MRI to detect pituitary tumors. […] Galactorrhea treatment may depend on the underlying cause. It may be medicines, surgical interventions, or lifestyle changes. […] Galactorrhea is often a symptom of an underlying condition such as pituitary tumors, thyroid disorders, or hormonal imbalances.
