The proliferative potential of human solid tumours, in vivo, was investigated using bromodeoxyuridine (BrdUrd) incorporation and flow cytometry (FCM). Patients with solid tumours from a variety of sites were injected with 500 mg BrdUrd, intravenously, several hours prior to biopsy or surgical excision. The labelling index (LI), duration of S-phase (Ts) and(More)
The maximum single dose of the 2-nitroimidazole hypoxic cell radiosensitiser Ro 03-8799 is limited to 1 g/m2 by the occurrence of a well characterised acute syndrome of sweating, nausea and mental changes. In an attempt to increase the tolerable dose, the clinical toxicity of the racemic mixture was compared with that of the R- and S-enantiomers of Ro(More)
The late radiation change observed in 15 patients treated for carcinoma of oral cavity or oropharynx using continuous hyperfractionated accelerated radiotherapy (CHART) was compared to that seen in 15 similar patients treated with conventional radiotherapy. The average follow up was, 31 and 33 months, respectively. A new dictionary for the recording of(More)
Both Ro 03-8799 and misonidazole were administered to six patients before tumour sampling. Using similar doses, tumour concentrations of Ro 03-8799 were approximately double those of misonidazole. Examination of the data with regard to the relative sensitising efficiencies of these two compounds gives us, as a conservative estimate, a factor of 1.6 in(More)
Misonidazole, SR-2508 and Ro 03-8799 have been given in sequence to patients before tumor sampling. Tumor concentrations of the three drugs have been measured and it has been possible to make prediction as to the likely advantage of the newer drugs over misonidazole. Based upon the three cases described here and 13 others given two drug combination, we(More)
High-dose chemotherapy (HDCT) followed by autologous blood cell (ABC) transplantation has been used widely for patients with metastatic breast cancer (MBC). It has been shown by our group and others to be an effective means of achieving very high response rates including complete remission. Therefore, further reduction in toxicity and increased patient(More)
In order to achieve the greatest advantage of accelerated hyperfractionated radiotherapy, treatment has been given 3 times each day for 12 consecutive days without a rest period. A total tumour dose of 50.4 Gy was well tolerated in a series of 38 patients with bronchial, head and neck and oesophageal carcinomas. A further 14 patients have now received an(More)
Smoking cigarettes during radiotherapy prolongs the period of reaction and may reduce the chance of cure. Of a group of 48 patients with advanced head and neck cancer 35 were smoking at the time of diagnosis, but 17 were persuaded to stop, although 7 relapsed later. Interviews conducted in 35 of the 48 patients revealed the problems which must be overcome(More)
