248 patients with locally radically treated early breast cancer (196 node-positive) were randomized post-operatively between 6 courses of a 'CMF like' chemotherapy and no further treatment. Results (with a minimum of 5 years follow-up on every patient) favour chemotherapy with a significant increase in the median time to recurrence from 31 to 50 months for all patients (P = 0.04) and from 26 to 49 months for node-positive patients (P = 0.023). No significant effect on survival is seen although there is a trend towards longer survival in the treated group. The regimen used was relatively non-toxic when compared to the traditional CMF with 34% of patients experiencing mild nausea and vomiting immediately post-injection and only 11% complaining of more severe nausea and vomiting. Because of this lower toxicity the treatment was found to be amenable to administration in both regional hospitals and specialized centres.

Photodynamic therapy utilizes a tumour-localizing photosensitive substance which, when activated by light of an appropriate wavelength, releases cytotoxic substances causing destruction of the malignant tumour with preservation of surrounding normal tissues. In this technique the only drug/light combination which has been regularly used to date is that of haematoporphyrin derivative and red light at a wavelength of 630 nm usually produced by a dye or gold vapour laser. A pilot/feasibility study was set up in Southampton in 1983, with ethical permission, to treat tumours of the skin and head and neck which had failed all other treatment modalities or for which there was no practical alternative therapy. Thirty-eight patients were treated in this study and all tumours showed a response; significant palliation was achieved in a number of patients. Basal cell carcinomas and the multiple lesions of Bowen's disease were found to be particularly suitable for this form of therapy and prolonged local control was achieved in a number of patients.

The early follow-up of patients treated by simple mastectomy alone or simple mastectomy combined with radical radiotherapy is presented. Both groups were well matched for age, menopausal status, duration of symptoms, size of tumour, and lymph-node involvement. There was no significant difference in survival of patients in the two groups at three years, but local recurrence was significantly more frequent (28%) in the mastectomy-alone patients. Early survival was not adversely affected by radiotherapy.
