Kopsavilkums
Intratumorālais iekaisuma infiltrāts, it īpaši neitrofilo leikocītu, mūsdienās tiek arvien vairāk aktualizēts kā pētniecības subjekts. Tomēr, patreiz publicētie dati bieži vien ir pretrunīgi. Attīstoties inovatīvām šūnu specifiskām terapijām, audzēju imūno un iekaisīgo šūnu komponentes izprašana kļūst arvien nozīmīgāka. Plaušu vēzis, kuru bieži vien raksturo slikta prognoze un augsta incidence, ir nozīmīgs kandidāts šāda veida izpētei.
Pētījuma mērķis bija apzināt iekaisīgo šūnu blīvumu dažādās audzēja daļās un veikt korelācijas analīzi ar audzēja izmēru (T parametrs) un limfmezglu statusu (N parametrs) plaušu adenokarcinomā (AK) un plakanšūnu karcinomā (PK).
Autors secināja, ka AK un PK, kas ir galvenie plaušu nesīkšūnu vēža tipi, raksturo atšķirīgas lokālās iekaisuma atbildes. AK ir sastopams nozīmīgi lielāks audzēja stromas eozinofilo leikocītu daudzums atšķirībā no PK. Tomēr, intratumorālās daļas imūnšūnu infiltrāta komponentes būtiski neatšķiras abu audzēja veidu starpā.
Analizējot AK tika novērota pozitīva korelācija ar intratumorālo neitrofilu daudzumu un T parametru, savukārt, stromālo monocītu un N parametra starpā tika novērota negatīva korelācija. Līdz ar to hipotētiski neitrofilu specifiska terapija varētu būt piemērota AK.
Intratumoural inflammatory infiltration, in particular neutrophils, represents a desirable target in nowadays research. However, the present published data are rather contradictory. With the development of innovative cell-specific therapies, in-depth studies of the immune and inflammatory cell component in tumours gain importance. Lung cancer, known for its dismal prognosis and high incidence, represents a reasonable research target. The goal of the study was to assess the density of inflammatory cells by tumour compartments in correlation with tumour size (T parameter) and nodal status (N parameter) in pulmonary adenocarcinoma (AC) and squamous cell carcinoma (SCC). The author concluded that AC and SCC, representing the main types of non-small cell lung cancers, are characterised by different local inflammatory responses. AC holds significantly higher count of stromal eosinophils in comparison with SCC. However, the intratumoural infiltrate shows no differences by tumour type. In AC, intratumoural neutrophils correlate positively with T parameter and stromal monocytes correlate negatively with N parameter. Therefore hypothetically, neutrophil-specific therapy could be beneficial in AC.
