Granulocytic sarcoma of the rectum: a rare complication of myelodysplasia.

A 67 year old man with myelodysplasia was admitted as an emergency with a six week history of rectal bleeding and diarrhoea. Barium enema showed an irregular polypoid filling defect in the lateral wall of the proximal rectum near the rectosigmoid junction. Histology showed this to be a granulocytic sarcoma (extramedullary granulocytic leukaemia; chloroma) infiltrating the bowel. A low index of suspicion of this lesion results in an incorrect diagnosis in many such cases. A chloroacetate esterase immunoperoxidase stain will confirm the granulocytic nature of the tumour cells.

Ultrasound-guided unilateral neck exploration for sporadic primary hyperparathyroidism: is it worthwhile?

The role of preoperative localisation tests before initial neck exploration for primary hyperparathyroidism (PHP) remains controversial, as does the optimal surgical approach. We report our experience with preoperative ultrasound (US) and the operative management of sporadic PHP between 1990 and 1995. Preoperative US was carried out by an experienced radiologist. Three surgeons adopted a policy of 'selective' US-guided unilateral neck exploration (UNE); the fourth surgeon performed routine bilateral neck exploration (BNE). There were 72 patients: 26 men and 46 women, with a mean age of 57.4 +/- 12.5 years (range 21-80 years). All patients underwent initial neck exploration for 'sporadic' PHP, of whom 63 had preoperative US. This was positive in 52 patients; 27 of whom underwent a UNE, 23 had a BNE, and two patients had a UNE converted to a BNE. Patients with 'negative' US (n = 11), and those receiving no preoperative localisation test (n = 90) underwent a BNE. The sensitivity, specificity and accuracy of US were 80% (52/65), 100% (61/61), and 90% (113/126), respectively. Comparable success rates were achieved (BNE: 97% (33/34) vs UNE: 93% (27/29), P < 0.05), with very low morbidity. Failures with the scan-guided UNE were caused by missed contralateral adenomas. An experienced radiologist and a low incidence of multiglandular disease (MGD) are essential prerequisites for the scan-guided unilateral approach. An experienced surgeon, on the other hand, is the only prerequisite for the 'gold standard' bilateral approach.

Serum albumin and CA125 are powerful predictors of survival in epithelial ovarian cancer.

OBJECTIVE: To assess the prognostic significance of presentation serum albumin, clinical stage and CA125 levels in ovarian cancer. DESIGN: Retrospective analysis of data using a Cox proportional hazards model. SETTING: A district general hospital oncology unit. SUBJECTS: One hundred and fourteen consecutive patients with epithelial ovarian cancer. INTERVENTIONS: Cytotoxic chemotherapy and surgery. MAIN OUTCOME MEASURE: Survival. RESULTS: A linear increase in risk was observed with high log CA125 (P < 0.0001) and with low albumin (P < 0.0001). In late stage patients (III and IV) albumin is the best predictor of survival (P = 0.0006). The presence of ascites, blood transfusion, type of surgery or chemotherapy did not improve the predictive model. CONCLUSIONS: CA125 and albumin can be used to identify prognostic subgroups independently of stage. Albumin alone can also be used as a predictor of survival. A simple classification of patients into three groups based on serum albumin of 41 g/l or more, 35 to 40 g/l and 34 g/l or less provides a clear separation of survival curves in the present group of patients.

An evaluation of mucin-like carcinoma associated antigen (MCA) in breast cancer.

Serum levels of mucin-like carcinoma associated antigen (MCA) were measured in 80 healthy women, 109 patients with breast cancer at presentation and in samples taken from 45 patients with active metastatic breast cancer. The MCA levels in controls had an upper limit of normal of 19.6 U ml-1 in post-menopausal and 16.4 U ml-1 in premenopausal women. The levels at presentation in stages I and II and III were not significantly different from the post-menopausal controls. Longitudinal studies over 5-9 years in 20 patients with stage I and II disease who had remained tumour-free showed a narrow MCA range for each individual patient, but the mean and range of a single measurement in a further 63 of these patients were similar to those of the normal controls. Rising MCA levels occurred in 12/14 patients who developed metastases in 2-8 years after surgery, but local recurrence was not associated with a rise of MCA. Eighty per cent of patients with active metastatic disease had MCA levels greater than 15 U ml-1. MCA levels fell during clinical responses to therapy in metastatic cancer. In the context of follow-up serum MCA levels appear to be a sensitive indicator of metastatic disease; caution is required in the interpretation of isolated measurements.

The occult rectal prolapse syndrome.

Occult rectal prolapse is a condition of young adults which causes problems in diagnosis. Symptoms consist of tenesmus and the passage of blood and mucus associated with constipation and straining at stool. The rectal prolapse often remains unrecognized for a long time because demonstration of the prolapse is difficult. There are characteristic changes in the rectum on clinical examination and these should alert the clinician to the diagnosis. Treatment of the prolapse relieves the symptoms.

Estracyt in advanced carcinoma of the breast: a phase II study.

Estracyt, a conjugate of an alkylating agent with an oestrogenic sterol, was given in a dose of 420 mg daily to a group of 44 postmenopausal patients with very advanced breast carcinoma. Thirty-eight of these were in relapse following chemotherapy and 32 had evidence of distant metastases. Seventeen patients had an objective response and marked or complete alleviation of symptoms, four others had a useful symptomatic response but no beneficial effect was observed in the remainder. Three who had shown no response to previous oestrogen therapy also failed to respond to Estracyt as did all nine patients with hepatic metastases. Oestrogen receptor status and age within the postmenopausal group seemed to have no bearing on the result. Side-effects were minimal with nausea in 18 patients but in only two did this necessitate withdrawal of the drug. Bone marrow depression did not occur. Changes in acute-phase reactant proteins suggested that part of the Estracyt was de-esterified in the liver liberating oestrone but the low incidence of vaginal haemorrhage and the recalcification of bony metastases suggested that on the whole Estracyt behaves as an anti-oestrogen as well as an antimitotic.

Ten-year survival rates in breast cancer using combination chemotherapy.

The outcome in 254 patients with all stages of breast cancer treated by combination chemotherapy is presented. All the patients were treated 10 or more years ago. The 10-year survival rate for Stages I and II combined is 60 per cent, in Stage III 19 per cent and in Stage IV 3 per cent. The combined rate in Stages I and II differed markedly according to hormonal status. In premenopausal patients the rate was 84 per cent compared with 42 per cent in postmenopausal patients.

Mortality after vagotomy and pyloroplasty for duodenal ulcer.

A retrospective survey of 4,026 patients having truncal vagotomy and pyloroplasty for duodenal ulceration showed a mortality rate of 1.4% (55 patients). On analysis the commonest causes of death were found to be bronchopneumonia 37% (18 patients) and sepsis 20% (10 patients). More than half of the deaths occurred in patients aged over 50.
