Glioblastoma multiforme

(Redirectum de Glioblastoma)

Glioblastoma multiforme sive Glioblastoma[1] est species cancri cerebri, qui haud sanabilis est. Nam quinque annos post morbum inventum, solum 2 centesimae hominum hoc cancro laborantium supersunt.[2] Causae huius morbi adhuc ignotae sunt.

Imago glioblastomatis cum falcem cerebri amota propter diffusionem tumorem.

Tractatio difficile restat, in parte diversitate microcircumiectorum immunologicorum cancri[3]. Adhuc therapiae adversus cancri angiogenesem ineffectivae videbantur[4].

Pathophysiologia

recensere

In morbi cursu cellulae gliomata numero crescunt. Microcircumiectorum planitie diversitas insolita inter cellulas neoplasticas et non neoplasticas emergit. Abundissime sunt cellulae generis tumori associatorum macrophagocytorum (TAM), ergo cellulae systematis immunitatis innati, quae 40% massa cancri constituunt[5].

Symptomata

recensere

Generalia indefinitivaque symptomata sunt convulsiones novae vel adhuc incognitae, capitis dolor, nausea, vomitus, memoriae spoliatio, ac alia symptomata neurologica circumscripta[6], quamquam spectrum symptomatum de tumoris loco pendat; per haec symptomata se attollere aut celerrime queant, aut longe occultare.

Classificatio glioblastomatum

recensere

Classificatio ordinis mundi sanitarii (WHO) anni 2016 notat:

  • Glioblastomata IDH1 mutanda
    • Glioblastoma cellularum gigantium
    • Gliosarcoma
    • Glioblastoma epitheloidum
  • Glioblastoma IDH1, typi ferocis
  • Glioblastoma non alibi specificatum

Comparatio classificationis 2016 cum veta 2017 criteria genetica addita esse ostendit: IDH mutandum et typum ferocem[7].

Tractatio

recensere

Adhuc sanatio glioblastomatis restat difficilis et estimatur tumorem recursurum esse[8]. Therapia per resectionem neurochirurgicam, radiotherapiam, chemotherapiam, et medicamentum temozolomidi fit.

Formae tractationis adhuc vel non generaliter probatae

recensere

In scientia hodierna medica novas tractationis formas investigantur[9] ut, verbi gratia, inhibitores receptorii EphA3, inhibitores EGFR (includens anticorpora monoclonalia), inhibitores VEGF.

Inhibitores VEGF

recensere

Glioblastomatibus multiformibus permulta vasa sanguinea sunt, ergo inhibitionem angiogenesis (generationis novorum vasorum sanguineorum) investigabatur. In angiogenesi factor crescentis endothelialis vascularis (VEGF) velut receptorium suum, receptorium VEGF (VEGFR), momenta habent. Adhuc tamen numquam strategia contra angiogenesem incrementum tumoris inhibere potuit. Effectus inhibitoris kinasum tyrosini Regorafenib incerti restant[10].

Interleukin 12

recensere

Interleukinum 12 (IL-12) est cytokinum cum effectibus contra cancrum. Nuper CHIOCCA et al. textui gliobastomatis genum IL-12 generantem applicaverunt[11].
