Histopathology data from 298 patients with breast cancer have been stored in a computer, and features influencing survival have been analysed by the life table method and presented in survival curves. Prognostic features assessed were the size, type, and grade of neoplasm, the amount of stromal elastosis and lymphocytic infiltrate, and the presence and number of axillary metastases. The most reliable indications of short survival are the presence of axillary metastases and a high tumour grade. These two features are correlated, as high-grade tumours are much more likely to have metastases at presentation. No statistical difference is found in the survival of patients with metastases in one or two axillary nodes compared with those with larger numbers involved. There are differences in survival in different types of carcinoma; the well-differentiated infiltrating duct carcinoma with tubular pattern has the best prognosis, followed by the medullary carcinoma. The size of the tumour has some prognostic significance, but this is outweighed by its grade.

Seven hundred and seventy-nine patients presenting with breast cancer in Tasmania between 1930 and 1975 have been studied. No comparisons of different treatment have been made, but overall survival has been assessed. Median survival in the group was only 3-3 years, but 30% of patients were still alive at ten years. Other factors assessed in relation to survival were axillary node involvement, site, size, age, parity, breast feeding and place of birth.

The pulse volume recorder has been used in studying 62 limbs to assess its accuracy in localization of arteriosclerotic lesions of the lower limbs, realizing the limitations of clinical examination and simple pressure measurements. Its advantages over simple pressure measurements are illustrated. It was shown to be most accurate in locating isolated stenoses. The technique helps differentiate aorto-iliac from high superficial femoral artery obstruction. It can be used when severe medial sclerosis is present and is very helpful when distal pulses cannot be detected for technical reasons.
