Rak piersi u mężczyzn
Rokowania, prognozy i postęp choroby

Rak piersi u mężczyzn (MBC) stanowi około 1% wszystkich nowotworów złośliwych u mężczyzn oraz 1% przypadków raka piersi. Prognozuje się, że w 2025 roku w USA zostanie zdiagnozowanych około 2800 przypadków inwazyjnego raka piersi u mężczyzn. Większość nowotworów jest hormonozależna, z dominującą rolą receptorów estrogenowych (ER) w proliferacji komórek nowotworowych. Pięcioletni i dziesięcioletni wskaźnik przeżycia względnego wynosi odpowiednio 84% i 72%, jednak mężczyźni mają gorsze przeżycie całkowite (5-letnie 77,6% vs 86,4% u kobiet). Kluczowe czynniki prognostyczne obejmują wiek (HR 1,89), stan węzłów chłonnych (5-letnie przeżycie 90% bez przerzutów vs 65% z przerzutami), stopień złośliwości histologicznej (G1: 76%, G3: 43%), status receptorów ER (HR 2,481), PR (HR 2,294), HER2 (HR 2,68), zaawansowanie kliniczne (HR 1,41), leczenie operacyjne (HR 0,38) i chemioterapię (HR 0,62). Podtypy molekularne mają istotny wpływ na rokowanie, z najgorszym przeżyciem dla potrójnie negatywnego (TN) (5-letnie CSS 43,2%, HR 10,676). Mężczyźni częściej diagnozowani są w zaawansowanym stadium (III/IV), co przekłada się na gorsze wyniki leczenia i wyższe ryzyko zgonu w porównaniu do kobiet.

Wprowadzenie do raka piersi u mężczyzn

Rak piersi u mężczyzn (MBC – Male Breast Cancer) jest rzadką chorobą, stanowiącą zaledwie 1% wszystkich nowotworów złośliwych u mężczyzn oraz około 1% wszystkich przypadków raka piersi. Według prognoz, w 2025 roku w Stanach Zjednoczonych zostanie zdiagnozowanych około 2800 mężczyzn z inwazyjnym rakiem piersi1. Podobnie jak w przypadku kobiet, większość nowotworów piersi u mężczyzn jest hormonozależna, gdzie działanie genomiczne receptora estrogenowego (ER) dyktuje programy transkrypcyjne napędzające proliferację komórek nowotworowych23.

Czynniki prognostyczne w raku piersi u mężczyzn

Rokowanie w raku piersi u mężczyzn zależy od wielu czynników. Badania wykazały, że 5-letni i 10-letni wskaźnik przeżycia względnego dla mężczyzn z rakiem piersi wynosi odpowiednio 84% i 72%4. Jednakże mężczyźni mają gorsze ogólne przeżycie w porównaniu do kobiet z rakiem piersi, przy podobnym przeżyciu specyficznym dla choroby5. W badaniu opublikowanym w JAMA Oncology, 5-letnie przeżycie całkowite po diagnozie raka piersi wynosiło 77,6% dla mężczyzn, w porównaniu do 86,4% dla kobiet6.

Niezależne czynniki prognostyczne

Liczne badania zidentyfikowały kluczowe czynniki prognostyczne dla rokowania w raku piersi u mężczyzn. Do najważniejszych z nich należą:

  • Wiek w momencie diagnozy (HR 1,89, 95% CI 1,50-2,38)7
  • Stan węzłów chłonnych – pacjenci z węzłami chłonnymi bez przerzutów mają 5-letni wskaźnik przeżycia wynoszący 90%, w porównaniu do 65% dla pacjentów z zajętymi węzłami8
  • Stopień złośliwości histologicznej – pacjenci z guzami G1 mają 5-letnie przeżycie na poziomie 76%, które spada do 65% dla G2 i 43% dla G39
  • Status receptora estrogenowego (ER) – negatywny status ER zwiększa ryzyko zgonu o 2,481 razy (HR 2,481, 95% CI 1,159-5,319)10
  • Status receptora progesteronowego (PR) – negatywny status PR zwiększa ryzyko zgonu o 2,294 razy (HR 2,294, 95% CI 1,256-4,184)11
  • Status HER2 (HR 2,68, 95% CI 1,20-5,98)12
  • Stan zaawansowania klinicznego (HR 1,41, 95% CI 1,15-1,74)13
  • Leczenie operacyjne (HR 0,38, 95% CI 0,29-0,51)14
  • Chemioterapia (HR 0,62, 95% CI 0,50-0,75)15
  • Stan cywilny (HR 0,75, 95% CI 0,63-0,89)16
  • Rasa – pacjenci rasy czarnej mają gorsze rokowanie (HR 2,322, 95% CI 1,442-3,74)1718
  • Lokalizacja guza – istotny niezależny czynnik prognostyczny19

Podtypy molekularne a rokowanie

Podtypy molekularne raka piersi u mężczyzn mają istotny wpływ na rokowanie. Badania wykazały znaczące różnice w 5-letnim przeżyciu całkowitym i przeżyciu specyficznym dla choroby (CSS) wśród różnych podtypów molekularnych. 5-letnie CSS dla poszczególnych podtypów wynosi20:

  • 89,2% dla HER2-/HR+
  • 78,4% dla HER2+/HR+
  • 72,6% dla HER2+/HR-
  • 43,2% dla potrójnie negatywnego (TN)

Podtyp potrójnie negatywny (TN) jest związany z 10,676-krotnie wyższym ryzykiem zgonu (HR 10,676, 95% CI 4,441-25,665) w porównaniu do innych podtypów21.

Porównanie rokowania u mężczyzn i kobiet

Badania wskazują, że mężczyźni z rakiem piersi mają gorsze rokowanie niż kobiety. Ponad 40% mężczyzn z rakiem piersi zgłasza się w stadium 3/4 choroby, co przekłada się na gorsze ogólne przeżycie22. W badaniu opublikowanym w JAMA Oncology wykazano, że nawet po uwzględnieniu wszystkich czynników klinicznych, mężczyźni nadal mieli o 19% wyższe ryzyko zgonu niż kobiety w ciągu 5 lat od diagnozy23.

Wyższy odsetek mężczyzn niż kobiet w badaniu miał raka piersi w IV stadium w momencie diagnozy (5,8% vs 3,8%)24. Pomimo ogólnie bardziej agresywnego przebiegu choroby, pacjenci płci męskiej częściej byli niedoleczeni w porównaniu do kobiet25. Charakterystyka kliniczna i niedoleczenie wyjaśniały tylko około dwie trzecie różnicy w śmiertelności26.

Istnieją również różnice w niezależnych czynnikach prognostycznych między mężczyznami a kobietami z rakiem piersi. PR i HER2 były niezależnymi czynnikami prognostycznymi dla kobiet, ale nie dla mężczyzn27. Z kolei receptor androgenowy (AR) i progesteronowy (PR) są korzystnymi markerami prognostycznymi w raku piersi u kobiet28.

Modele prognostyczne dla raka piersi u mężczyzn

Nomogramy jako narzędzia prognostyczne

W ostatnich latach opracowano kilka modeli prognostycznych specyficznych dla raka piersi u mężczyzn. Jednym z nich jest nomogram, który łączy cechy prognostyczne raka piersi u mężczyzn i przewiduje przeżycie całkowite (OS)2930.

Model opracowany przez badaczy z Chin, wykorzystując dane z rejestru SEER, uwzględnia 7 zmiennych: wiek, status operacji, stan cywilny, stadium guza, stadium kliniczne, chemioterapię i status HER231. Nomogram ten wykazał dobrą dokładność i wiarygodność zarówno w walidacji wewnętrznej, jak i zewnętrznej32.

Inny nomogram, opracowany przez badaczy z wykorzystaniem analizy konkurujących ryzyk, pokazał dobrą dokładność w przewidywaniu rokowania u pacjentów z nieprzerzutowym rakiem piersi u mężczyzn33. Według tego modelu, rasa czarna, negatywny status PR, zaawansowane stadium T/N/grade i brak operacji były niezależnie związane ze zgonami spowodowanymi rakiem piersi (BCSD). Z kolei podeszły wiek, brak związku małżeńskiego, zaawansowane stadium AJCC i brak chemioterapii skutkowały większym prawdopodobieństwem zgonu z innych przyczyn (OCSD)34.

Nomogram skonstruowany w badaniu z udziałem 1224 pacjentów z rakiem piersi u mężczyzn wykazał, że status receptora estrogenowego (ER) stanowił zdecydowaną większość proporcji w porównaniu z innymi cechami klinicznymi35. Model ten przewyższał system klasyfikacji AJCC, co wykazano w analizie krzywej decyzyjnej (DCA)3637.

Adaptacja modeli prognostycznych z żeńskiego raka piersi

Interesującym odkryciem jest to, że modele prognostyczne pierwotnie opracowane dla raka piersi u kobiet również dobrze sprawdzają się w przypadku mężczyzn. Modele takie jak3839:

  • Multivariate Prognostic Index (MPI) – oparty na indeksie mitotycznym, wielkości guza i statusie węzłów chłonnych
  • Nottingham Prognostic Index (NPI) – uwzględniający stopień złośliwości, wielkość guza i status węzłów chłonnych
  • Adjuvant! – kompleksowy model uwzględniający wiele czynników klinicznych
  • Predict – narzędzie online do przewidywania rokowania i korzyści z terapii

Wszystkie te modele wykazały dobrą zdolność do dyskryminacji między pacjentami z dobrym, umiarkowanym i złym rokowaniem40. To potwierdza, że modele pierwotnie opracowane i walidowane dla pacjentek z rakiem piersi sprawdzają się również dość dobrze w przypadku mężczyzn41.

Specyfika wiązania receptorów hormonalnych

Analiza genomowego działania receptorów hormonalnych ujawniła specyficzne dla płci i lokalizacji genomowej działanie receptorów hormonalnych, które są powiązane z przeżyciem u pacjentów z rakiem piersi u mężczyzn42. Badania wykazały, że chociaż większość miejsc wiązania ER jest wspólna dla nowotworów piersi u mężczyzn i kobiet, miejsca ER związane z rokowaniem pacjentów są specyficzne dla płci43.

Znacząca proporcja miejsc wiązania ER pokrywa się z miejscami AR i GR, co potwierdzono w danych linii komórkowych i nowotworów piersi u mężczyzn44. Globalna selektywność wiązania chromatyny ER i FOXA1 ujawnia specyficzne dla płci cechy prognostyczne, które skutecznie klasyfikują pacjentów z rakiem piersi u mężczyzn pod względem przeżycia45.

Ryzyko rozwoju innych nowotworów

Mężczyźni, którzy przeżyli raka piersi, mają podwyższone ryzyko rozwoju innych nowotworów. Wieloośrodkowe badanie międzynarodowe, które połączyło dane z 13 rejestrów nowotworów, wykazało, że 12,5% z 3409 ocalałych z MBC zachorowało później na inny (nie piersi) nowotwór46. Ryzyko nowych pierwotnych nowotworów było podwyższone w jelicie cienkim, odbytnicy, trzustce, skórze (niemelanocytowe), prostacie oraz układzie limfatycznym/krwi47.

Podsumowanie i wnioski

Rak piersi u mężczyzn, mimo że jest rzadkim schorzeniem, charakteryzuje się zróżnicowanym rokowaniem w zależności od wielu czynników. Mężczyźni generalnie mają gorsze rokowanie niż kobiety, co częściowo wynika z późniejszej diagnozy i częstszego niedoleczenia. Czynniki takie jak wiek, status receptorów hormonalnych, stopień zaawansowania choroby, podtyp molekularny oraz zastosowane leczenie mają kluczowe znaczenie dla rokowania.

Opracowane nomogramy i modele prognostyczne pozwalają na dokładniejsze przewidywanie przeżycia pacjentów z rakiem piersi u mężczyzn, co może pomóc w podejmowaniu decyzji klinicznych dotyczących leczenia uzupełniającego i informowaniu pacjentów. Co ciekawe, modele prognostyczne pierwotnie opracowane dla kobiet również dobrze sprawdzają się w przypadku mężczyzn.

Dalsze badania są niezbędne, aby lepiej zrozumieć biologię raka piersi u mężczyzn, co może prowadzić do opracowania bardziej skutecznych strategii leczenia dostosowanych do specyficznych potrzeb pacjentów płci męskiej48.

    Male breast cancer (MBC) is rare and poorly characterized. Like the female counterpart, most MBCs are hormonally driven, but relapse after hormonal treatment is also noted. […] Here we report the characterization of human breast tumors of both genders for cistromic make-up of hormonal regulation in human tumors, revealing genome-wide chromatin binding landscapes of ER, AR, PR, GR, FOXA1, and GATA3 and enhancer-enriched histone mark H3K4me1. We integrate these data with transcriptomics to reveal gender-selective and genomic location-specific hormone receptor actions, which associate with survival in MBC patients. […] The majority of male (and female) breast cancers are hormonally driven, where ER genomic action dictates transcriptional programs that drive tumor cell proliferation. […] Even though the genomic action of ER in MBC remains completely elusive, multiple reports have studied ER genomics in the female disease.

    AR and PR are favorable prognostic markers in female breast cancer (FBC). […] Cumulatively, these data illuminate the likely interplay between different steroid hormone receptors in breast cancer. […] This comprehensive overview reveals gender-selective and genomic location-specific hormone receptor action, which associate with survival in MBC. […] MBC is ER-driven. […] A significant proportion of ER binding sites overlap with AR and GR sites as seen in cell line data which we confirmed in MBC. […] Although we found the vast majority of ER sites to be shared between male and female breast cancers, ER sites that are associated with patient outcome appeared gender-selective. […] We performed logistic regression with elastic net regularization to construct a supervised binary classification model by which predictive gene signatures could be identified, which was trained in our cohort and tested in the validation cohort. […] Cumulatively, we show that global ER and FOXA1 chromatin binding selectivity reveals gender-specific prognostic features that successfully classify MBC patients on survival.

    Men may be more likely than women to die after being diagnosed with breast cancer, particularly during the first 5 years after diagnosis, a new study suggests. […] In the study, the 5-year overall survival rate after a diagnosis of breast cancer was 77.6% for men, compared with 86.4% for women, researchers reported in JAMA Oncology on September 19. […] However, after all those factors were accounted for, male patients still had 19% higher chance of dying than female patients within 5 years of diagnosis. […] The results of this retrospective study suggest that men with breast cancer deserve dedicated studies that will help us to better understand the biology of the disease in males, Dr. Zimmer said. […] In the study, men had higher death rates than women across all stages of breast cancer, even after the researchers adjusted for differences in patients clinical characteristics, such as the type and stage of disease, treatments received, age, race/ethnicity, and access to care.

    Also, grade 1 patients have a five-year survival of 76%, dropping to 65% for those with grade 2 tumours and 43% for grade 3 MBC (Fentiman, 2009). […] In more recent studies, ER negativity (Ruddy and Winer, 2013; Abreu et al., 2016), fibrotic focus 8 mm, hypoxia-inducible factor-1 overexpression and nuclear area (Kornegoor et al., 2012a; Veta et al., 2012) appear to be prognostic factors in MBC too. […] There is no or little evidence of a correlation between HER2, Ki67, PR or lymphovascular invasion and prognosis (Ruddy and Winer, 2013). […] Prognostic models that have been developed for FBC like the Multivariate Prognostic Index (consisting of mitotic index, tumour size and lymph node status), Nottingham Prognostic Index (consisting of grade, tumour size and lymph node status), Adjuvant! and Predict seem to perform quite well for MBC patients too (van der Pol et al., 2016).

[…] Although we found the vast majority of ER sites to be shared between male and female breast cancers, ER sites that are associated with patient outcome appeared gender-selective. […] We performed logistic regression with elastic net regularization to construct a supervised binary classification model by which predictive gene signatures could be identified, which was trained in our cohort and tested in the validation cohort. […] Cumulatively, we show that global ER and FOXA1 chromatin binding selectivity reveals gender-specific prognostic features that successfully classify MBC patients on survival.

    Interestingly, a multicenter international study that pooled data from 13 cancer registries found that 12.5% of 3409 MBC survivors went on to develop a different (non-breast) cancer, and that risk of new primary cancers was elevated in the small intestine, rectum, pancreas, skin (non-melanoma), prostate, and lymphatics/blood. Other more recent studies have confirmed an elevated risk for other cancers in MBC survivors (Ruddy and Winer, 2013).

  • #48 Men with Breast Cancer Have Higher Mortality than Women – NCI

    Men may be more likely than women to die after being diagnosed with breast cancer, particularly during the first 5 years after diagnosis, a new study suggests. […] In the study, the 5-year overall survival rate after a diagnosis of breast cancer was 77.6% for men, compared with 86.4% for women, researchers reported in JAMA Oncology on September 19. […] However, after all those factors were accounted for, male patients still had 19% higher chance of dying than female patients within 5 years of diagnosis. […] The results of this retrospective study suggest that men with breast cancer deserve dedicated studies that will help us to better understand the biology of the disease in males, Dr. Zimmer said. […] In the study, men had higher death rates than women across all stages of breast cancer, even after the researchers adjusted for differences in patients clinical characteristics, such as the type and stage of disease, treatments received, age, race/ethnicity, and access to care.
