E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The aim of the study is to prove the potential of 11C-MET PET/CT optimized radiotherapy to prolong the progression free survival in the group of glioblastoma patients with rapid early progression (Arm A) if compared with respective historical retrospective cohort (Arm Ahist). |
Cílem je prokázat, že při optimalizaci radioterapie pomocí 11C-MET PET/CT se prodlouží čas do progrese (PFS) pacientů s časnou pooperační progresí GB (rameno A) ve srovnání s odpovídající historickou retrospektivní skupinou pacientů (rameno Ahist). |
|
E.2.2 | Secondary objectives of the trial |
• Prospective assessment of the incidence of REP on planning MRI in GB patients indicated to adjuvant chemoradiotherapy. • Evaluation of PFS in the group of patients with REP undergoing the MET PET optimized RT (Arm A) vs. PFS in the group of patients with no REP (Arm B). • Evaluation of overal survival (OS) in the group of patients with REP undergoing the MET PET optimized RT (Arm A) vs. OS in the respective historical retrospective cohort (Arm Ahist) vs. OS in the group of patients with no REP (Arm B). • Univariate and multivariate analysis of clinical factors and laboratory biomarkers in the whole group of prospectively enrolled GB patients, and in respective arms. • Identification of basic clinical and laboratory biomarkers of REP applicable to clinical practice. • Evaluation of spatial patterns of failure (central vs. in-field vs. marginal vs. distant) in MET PET cohort (Arm A) in comparison to retrospective REP cohort (Ahist.).
|
• Prospektivní zhodnocení výskytu REP na plánovací MR u pacientů s GB indikovaných k adjuvantní chemoradioterapii. • Vyhodnocení PFS při optimalizaci RT pomocí MET PET pacientů s REP (rameno A) ve srovnání se skupinou pacientů bez REP (rameno B). • Vyhodnocení celkového přežití (OS) při optimalizaci RT pomocí MET PET pacientů s REP (rameno A) ve srovnání s historickou retrospektivní skupinou pacientů (rameno Ahist) a se skupinou pacientů bez REP (rameno B). • Univariační a multivariační analýza pro OS a PFS klinických charakteristik a laboratorních biomarkerů v celém souboru zařazených pacientů a v jednotlivých ramenech. • Identifikace základních klinických a laboratorních biomarkerů pacientů s REP, které lze aplikovat v klinické praxi. • Prostorové vyhodnocení recidiv (patterns of failure, PoF) u pacientů s REP (rameno A) ve srovnání s historickou retrospektivní skupinou pacientů (rameno Ahist). |
