- The combination of microwave-induced (2450 MHz) hyperthermia and ionizing radiation was used in 7 patients with superficial malignant tumours, which were considered refractory to other therapy. A newly developed heating system was used, allowing for a maintained temperature at the master probe of 42.5 degrees C +/- 0.5 degrees C during 45 min, but temperature measurements at multiple sites showed a marked variation. This preliminary series indicates that the combination of hyperthermia and ionizing radiation may be useful, the response rate (complete or partial) being 8 of 8 evaluable lesions. Even previously heavily irradiated sites responded. Technical improvements are highly needed to allow for controlled heating of any tissue volume.

- Subcutaneous metastases from an oesophageal carcinoma were irradiated using different schedules. The results have to be evaluated with greatest caution but indicate that with the same CRE value, few fractions caused less skin reactions than several, and the size of the shoulder of the cell survival curve was of the order of 0.7 Gy.

Technique for microwave-induced hyperthermia in superficial human tumours

Tidskriftsartikel (refereegranskat)abstract
- In order to induce local hyperthermia in superficial tumours a computer system using a 2,450 MHz microwave generator connected to a circular (diameter 90 mm) direct contact applicator was constructed based on invasive temperature control. Small thermistor probes with a diameter of 0.6 mm are inserted in the tumour and surrounding tissues. Eight thermistors can be used simultaneously and one of them is chosen as the "master'. The automatic control system used a pulsed irradiation technique to avoid the problem with interactions between the metallic wires of the temperature probe and the electromagnetic field. With the system it was possible to control the temperature at the master thermistor within +/- 0.5 degrees C from the preset value.

Relation between tumour size and plasma prolactin levels in premenopausal patients with breast carcinoma : A preliminary report
- 1985
-
Ingår i: Acta Radiologica: Oncology. - : Informa UK Limited. - 0349-652X. ; 24:1, s. 57-59

Tidskriftsartikel (refereegranskat)abstract
- In thirty-one premenopausal patients with carcinoma of the breast the plasma prolactin was measured after mastectomy. A highly significant correlation between tumour size and plasma prolactin levels (p<0.002) was observed after adjustment for age at diagnosis and parity. At the time of the prolactin determination no clinical signs of metastatic disease were evident, suggesting that the prolactinc levels were unrelated to the tumour burden.
