| Popis: | Purpose: This study aimed to evaluate the impact of tumor volume on platelet counts (PLT) and mean platelet volume (MPV) and involve these parameters on overall survival. Methods: It is a retrospective study of 99 patients with lung cancer (confirmed histologically or cytologically). Sixty-six patients underwent radical operating treatment and 33 patients had only biopsies – due to the inoperable status of tumor According to the histopathology profile: non-small cell carcinoma – 23%, adenocarcinoma - 23 %, squamous - 36%, small cell carcinoma -11%, carcinoid – 6%. The overall survival was measured from the time of surgery to last observation or death. The tumor’s size was established based on information from histopathology protocol by using model for the ellipsoid (V=4/3 π r abc). Results: KM median survival time after surgery was 20 months (95% C.I. = 16–42). The survival time depends significantly on: Tumor feature, MPV (p=0.03, p=0.04). Patients with normal PLT levels have longer survival time (median: 11 months) than thrombocytosis group (9.5) (p=0.6). Following both the PLT and MPV, a change-point that is equal to approximately 18.5 cm3 (approx. 3.3 cm in diameter) stands for a segmented relationship between tumor volume and analyzed blood indicators. Conclusions: After an overstepping of the change-point of tumor volume inflammatory processes start and they are associated with poor prognosis. MPV may be a valuable biomarker for the diagnosis and follow up of various types of carcinoma. |
