Oesophageal intubation occasionally fails to palliate inoperable carcinoma: some tumours are unsuitable for this procedure and others overgrow the tube. This study reports a series of nine patients (median age 79 (range 55-87) years) in whom the argon beam monopolar coagulator via a flexible endoscopic probe was used to ablate such tumours. Fourteen ablation procedures were performed. ⋯ Thirteen procedures rendered the patients completely asymptomatic for a median of 6 (range 4-12) weeks. Six patients died a median of 14 (range 4-38) weeks after the first ablation, reflecting their limited life expectancy. The argon beam coagulator provides an effective alternative to laser ablation, being considerably cheaper and safer, while maintaining the minimally invasive nature of the palliation.

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.

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.

The risk of developing recurrent tumour was assessed in a group of 85 patients with primary colorectal cancer who had a negative intraoperative ultrasonographic examination at the time of primary tumour resection. At a median follow-up of 40 months liver metastases had developed in 14 patients (16 per cent). ⋯ Sixteen patients (19 per cent) presented with extrahepatic recurrence, one of whom also developed liver metastases. A negative intraoperative ultrasonographic examination did not prove to be a favourable prognostic factor which allowed exclusion from follow-up or adjuvant chemotherapy.
