[en] Further results are tabulated to the authors' experiences with hypothermic hyperbaric irradiation of advanced head and neck cancer (Sealy et al 1986). Thirty-nine patients were to have had hypothermic hyperbaric irradiation, but in two early patients, treatment was abandoned because of reversible hypotension or cardiac arrhythmia. Thirty-seven patients, therefore, received this treatment. The initial aim was to give two hypothermic treatments at weekly intervals at the beginning of treatment (seven patients) but this proved to be impracticable. The second group (21 patients), therefore, received one initial hypothermic irradiation, and a third group (nine patients) received a single hypothermic irradiation after four fractions in air and then completed their irradiation in air.

[en] Twenty-four patients receiving post-operative radiotherapy for testicular tumours have been studied to assess the impact of treatment errors. Regular treatment verification radiographs were performed and compared with simulator planning radiographs. It was demonstrated that lymph nodes in the area most at risk, i.e., para-aortic nodes at L1 to L3 on the ipsilateral side, were inadequately irradiated on 10% of treatments, and that at least one lymph node miss was recorded in 12 of the 24 patients. These results are considered to be a minimum estimate. Mostly para-aortic fields 8.0 cm wide were used, but it was shown that the number of lymph-node misses could have been substantially reduced by using fields 9.0 cm wide, whilst the consequent increase in irradiated kidney volume was considered acceptable.
