Brief Summary

Since radiation dose escalation to a large volume of tumour inevitably will induce higher toxicity than is currently the case, efforts must be made to limit the volume of tissue irradiated. Moreover, the irradiation of larger tumour volumes leads to a lower achievable tumour dose when keeping the normal tissue doses constant. Central is thus the question whether it would be possible to limit the volume of tumour to be boosted by selectively escalating the radiation dose to specific disease sites which are theoretically more prone to relapse.

Detailed Description

Hypoxic imaging with PET scans seems attractive for this purpose as hypoxia is associated with resistance for radiotherapy and approximately 70 % of SCLC are severely hypoxic at diagnosis[2].

We hypothesize that it might be possible to use a selective boost in these patients to tumor areas which are still hypoxic at the end of the standard chemo-radiotherapy to a dose of 45 Gy in 30 fractions in 3 weeks.

This way all SCLC (small cell lung cancer) patients can receive a safe, but higher dose of radiotherapy to the whole tumor volume, while the most resistant areas receive the highest possible dose.

This is a hypothesis generating trial designed to deliver at least the current standard treatment to malignant tissue while defining patient selection criteria for future study.
