Cancer Treatment
Surgery
removes the local tumor, invasive
Radiation oncology
irradiates the local tumor and kills the cancer
cells, non invasive with the exception of
interventional radiation treatment
(brachytherapy)
Medical oncology
i. v. application of medicaments
(chemotherapy, etc.), compared with radiation
the cell kill of medicaments is much lower

TRANSLATIONAL PART OF THE STUDY (TUMOR HYPOXIA)
Investigating whether tumor hypoxia can be visualized by 18F-FMISO-PET
before start of radiation treatment and whether the PET hypoxic subvolumes of a single tumor
are constant over a time axis of 2-3 days
(Molls and Pigorsch, 2010

Klinik und Poliklinik für Strahlentherapie und Radiologische Onkologie
The 3 main questions
•
Improves dose escalation the locoregional tumor control?
•
Is there a volume or a hypoxia effect in dose escalation?
•
How reliable is the PET visualization of tumor hypoxia?
