Do Selective Radiation Dose Escalation and Tumour Hypoxia Status Impact the Locoregional Tumour Control After Radiochemotherapy of Head & Neck Tumours?
Phase III A Prospective, Randomized, Rater-blinded, Multicentre Interventional Clinical Trial. Do Selective Radiation Dose Escalation and Tumour Hypoxia Status Impact the Locoregional Tumour Control After Radiochemotherapy of Head & Neck Tumours?

The major clinical problem and predominant cause of death after radio-oncological treatment of H+N cancers are loco-regional relapses. This randomized trial tests the hypothesis that dose escalated Intensity Modulated Radiotherapy (IMRT) selectively applied to the macroscopic primary tumor and involved neck nodes - which both in 80% - are hypoxic improves loco-regional control by at least 15% at 2 years. IMRT is combined with concurrent Cis-Platin chemotherapy. Tumor volume which correlates with number of malignant cells as well as tumor hypoxia are important biological parameters which increase radio-resistance, failure of local control and tumor progression. Basing on data of experimental and clinical radiation oncology we consider hypoxia as a useful parameter for pre-therapeutic strati-fication in future randomized radio-chemotherapy trials.

In addition, hypoxia imaging by PET can be used for testing the significance of selective dose escalation on hypoxic tumor sub-volumes ("Dose Painting").

As a prerequisite for such innovative studies addressing hypoxia the translational part investigates the following key issues: correlation between the size of total tumor volume (primary, lymph nodes) and hypoxic sub-volume, the spatial shift of the hypoxic sub-volume before start of treatment and the correlation of loco-regional control and hypoxia.

The study is a multicenter phase III randomized trial on the effect of dose escalated radiotherapy with concomitant chemotherapy to treat local advanced head and neck cancer. The study compares two treatment arms:

Experimental intervention (group A): 7 weeks standard radio-chemotherapy with 20 mg/m²/d Cisplatin in week 1 and 5 including simultaneous radiation dose escalation (5x2.3 Gy per week up to 80.5 Gy total dose) to the primary tumour and involved neck nodes ≥ 2 cm.

The Dose Escalated tumour Volume (DEVPT) is defined by the macroscopic (Gross) primary Tumour Volume (GTVPT) minus a 3 mm margin at organs at risk or at mucosal sites to reduce the risk of high dose deposition at the surrounding normal tissue. All involved lymph nodes visualized by CT with a minimal diameter of 2 cm are also included for dose escalation (DEVLN). The DEVLN of the lymph nodes > 2 cm is determined by the involved lymph node volume (GTVLN) minus a margin of 3 mm at organs at risk or mucosal sites. The 3 mm margin as well as the part of the target volume with suspected microscopic tumor extension receives 2 Gy per fraction.

Control intervention (group B): 7 weeks standard radio-chemotherapy with 5x2.0 Gy per week up to a total dose of 70 Gy and 20 mg/m²/d Cisplatin in week 1 and 5.

In group A and B: The treatment of the elective cervical lymphatic areas is given in the same session as the GTV but with a single dose of 1.6 Gy up to 56 Gy (so called simultaneous integrated boost concept).
