Papillary microcarcinomas are a specific subgroup of papillary thyroid cancer. They have the same histological features as papillary thyroid cancer but are 1.0 cm or less in diameter. ⋯ As papillary microcarcinomas can represent up to 30 per cent of all papillary cancers seen in a thyroid surgeon's practice, they are an important group. The aim of this review article is to outline the natural history of papillary microcarcinoma and to offer therapeutic management strategies.

Quality of life following resection of oesophageal carcinoma was assessed by patients using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and by a psychologist using the Spitzer Index. Quality of life was evaluated in 119 patients on one occasion 12 months after operation and in 30 patients regularly, starting with a preoperative assessment. Self and external evaluation showed a significant correlation (r = 0.61), but quality of life was assessed as being higher by the external observer. ⋯ Of several factors analysed only tumour recurrence (P < 0.01) and anastomotic stricture (P < 0.05) lowered quality of life significantly. Compared with the preoperative assessment, quality of life had decreased on discharge from hospital but was restored within 6 months of operation in disease-free patients. Further studies are required to determine the impact of adjuvant therapy for quality of life in patients undergoing surgery for oesophageal cancer.

Multiple bilateral fibroadenomas are uncommon. This finding in four women who had received renal transplants prompted further inquiry. A prospective study was performed on 39 women under the age of 55 years who had received a renal transplant at least 1 year earlier. ⋯ No abnormal breast findings were seen in 10 patients immunosuppressed with steroids and azathioprine alone (chi 2 = 7.30, 1 d.f., P < 0.01). Serum oestradiol concentration was raised in women with fibroadenomas compared with that in those with normal breasts (P < 0.05) and the level of FSH was lower (P < 0.01). Cyclosporin A may act on breast fibroblasts by humoral mechanisms and direct action.

Despite improved surgical techniques there is still a risk of mortality in elective general surgery. In a prospective study preoperative data from 3250 patients were collected and compared with postoperative systemic complications, using univariate chi 2 analysis. Highly significant (P < 0.00001) variables were subjected to stepwise logistic regression analysis. ⋯ Using these four variables, a simple preoperative risk scoring system has been defined. Class A (up to 5 points) was defined as a low-risk group (systemic complication rate 5.0 per cent), class B (5-7 points) was intermediate risk (systemic complication rate 17.9 per cent) and class C (8-10 points) was high risk (systemic complication rate 33.3 per cent). Patients at high risk for perioperative and postoperative complications are more likely to be identified by this analysis than by using the ASA classification alone.

Between 1947 and 1992, 1403 patients with 1432 salivary gland tumours were treated at the Christie Hospital, Manchester. There were 1194 epithelial neoplasms: parotid, 1082 (91 per cent); submandibular, 47 (4 per cent); minor glands, 65 (5 per cent). The commonest histological diagnoses were pleomorphic adenoma (n = 776) and adenolymphoma (n = 159). ⋯ The recurrence rate following the treatment of 551 new parotid pleomorphic adenomas was 1.6 per cent at median follow-up 12.5 (range 1-34) years, increasing to 15 per cent in the secondarily referred group (n = 170). For patients with definitively treated primary salivary carcinomas (n = 148), the disease-free survival rate at 5, 10 and 15 years was 58, 47 and 45 per cent respectively. Using multivariate analysis, clinical stage was the most important predictor of survival; the 10-year survival rate for stages I-IV was 96, 70, 47 and 19 per cent respectively.
