Förbättra hjärntumörresektion hos barn.
|
|
E.2.2 | Secondary objectives of the trial |

Använda fluorescenstekniker (avbildning och punktmätning) för att finna tumörgräns. Jämföra fluorescensmätning med mikroskopi och punktmätning med histologi, andra avbildande tekniker (tex. MRI, ultraljud) och kirurgens visuella avläsning. |

E.5 End points |
E.5.1 | Primary end point(s) |
The fluorescense microscopy increase the possibility to identify the tumour margins during tumour resection. The probe technology detect weak fluorescence better than the microscope in the tumour and tumour border zone. |
Fluorescensmikroskopet ökar kirurgens möjlighet att se tumören vid operationen. Probtekniken detektera svag fluorescens bättre än mikroskopet i tumör och tumörgräns. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
During surgery. |
Under kirurgin. |
|
E.5.2 | Secondary end point(s) |
The fluorescens intensity recorded by the probe is objectified and calculated as a number displaying the strength. The number is especially helpful in the borderzon, compared to the microscope. The fluorescence strength and the biopsy results agree and can be devided into groups representing different tissue types. The resected volume as calculated from the MRI is related to the clinical outcome of the operation. |
Fluorescenssignalen från proben kan objektifieras genom att ett värde motsvarande styrkan i fluorescensen beräknas. Detta värde är tydligare i tumörens randzon jämfört med fluorescensen från mikroskopibilden. Biopsiresultat och fluorescensensstyrka överensstämmer och kan indelas i grupper som motsvarar olika vävnader. Den borttagna tumörvolymen som beräknas från MRI relateras till det kliniska resultatet. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Postoperatively within three months after surgery. |
Postoperativt, inom tre månader efter genomförd kirurgi. |
