Mogu li hemocitometrijski parametri poslužiti kao bioloŔki biljezi u razlikovanju adrenalnih adenoma i karcinoma te u prognozi adrenokortikalnih karcinoma?
Recently, studies have reported that inflammatory response and elevated platelet counts are associated with several cancers. In the present study, we aimed to evaluate hemocytometer parameters in differentiating adrenal adenoma and carcinoma, and the prognostic utility of hemocytometer parameters in adrenocortical carcinoma (ACC). We included 30 patients with nonfunctional adrenal adenoma and 13 patients with ACC having undergone surgery between 2005 and 2017 and followed up postoperatively at our centre. The neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), red blood cell distribution width (RDW), mean platelet volume (MPV) and plateletcrit (PCT) were evaluated preoperatively in all patients included in the study. There was a significant difference between the adrenal adenoma and ACC groups in terms of neutrophil and lymphocyte counts, NLR and PLR. There was no significant difference between the two groups in terms of platelet count and MPV, but PCT levels were significantly lower in ACC group. There was no statistically significant difference between recurrent and/or metastasis positive patients and negative ones according to NLR, PLR, RDW and MPV. There was a statistically significant difference in RDW levels and tumor diameter between the groups. Our study is the first to evaluate hemocytometer parameters in differentiating adrenal adenomas and carcinomas, and also in the prognosis of ACC. The present study suggested that the hemocytometer parameters may be a marker in the differential diagnosis of adrenal adenomas and carcinomas. However, our study also showed that these parameters had no prognostic value in ACC.Nedavna istraživanja pokazuju da su upalni odgovor i poviÅ”eni trombociti udruženi s nekim vrstama karcinoma. Cilj naÅ”ega istraživanja bio je procijeniti hemocitometrijske parametre u razlikovanju adrenalnog adenoma i karcinoma, kao i prognostiÄku vrijednost hemocitometrijskih parametara u adrenokortikalnom karcinomu (adrenocortical carcinoma, ACC). U istraživanje smo ukljuÄili 30 bolesnika s nefunkcionalnim adrenalnim adenomom i 13 bolesnika s ACC operiranih izmeÄu 2005. i 2017. godine i poslije operacije praÄene u naÅ”oj ustanovi. Kod svih bolesnika ukljuÄenih u studiju prijeoperacijski su izmjereni sljedeÄi parametri: omjer neutrofila i limfocita (neutrophil/lymphocyte ratio, NLR), omjer trombocita i limfocita (platelet/lymphocyte ratio, PLR ), Å”irina distribucije eritrocita (red blood cell distribution width, RDW ), srednji volumen trombocita (mean platelet volume, MPV) i pleteletkrit (PCT). UtvrÄena je statistiÄki znaÄajna razlika izmeÄu skupina bolesnika s adrenalnim adenomom i onih s ACC u broju neutrofila i limfocita, NLR i PLR. Nije bilo znaÄajne razlike meÄu skupinama u broju trombocita i MPV, ali su razine PCT bile znaÄajno niže u skupini s ACC. Nije bilo statistiÄki znaÄajne razlike u NLR, PLR, RDW i MPV izmeÄu bolesnika s opetovanim ACC i/ili metastazama i onih bez tih stanja. StatistiÄki znaÄajna razlika izmeÄu skupina naÄena je za razine RDW i promjer tumora. NaÅ”e istraživanje je prvo te vrste u kojem su se procjenjivali hemocitometrijski parametri u razlikovanju adrenalnih adenoma i karcinoma te u prognozi ACC. Rezultati studije ukazuju na to da bi se hemocitometrijski parametri mogli primijeniti kao biljezi u diferencijalnoj dijagnostici adrenalnih adenoma i karcinoma. MeÄutim, naÅ”e je istraživanje pokazalo kako ovi parametri nemaju prognostiÄku vrijednost kod ACC
