Coumarin (1,2-benzopyrone) as a daily oral dose of 50 mg was evaluated in a multicentre prospectively randomized, double-blind, placebo-controlled trial to prevent early recurrence of malignant melanoma TNM Stage IB (Breslow thickness greater than 1.70 mm) and Stage II. Intake for the trial started in 1984 and was stopped prematurely, after review, in 1987.(More)
Both coumarin (1,2-benzopyrone) and warfarin (4-hydroxycoumarin) have been shown to prevent the recurrence of malignant melanoma. Their action is macrophage-dependent and the dosage is critical. In 1984 a multicentre, prospective, randomised, double-blind trial of coumarin, given as a daily 50-mg dose for 2 years after surgery in patients with high-risk(More)

In view of inconsistencies which have now become apparent in the data from one of the twenty-eight centres which took part in the trial, the results of the trial have been re-examined,(More)
Many recent reports in the North American literature have documented an increase in the ratio of proximal to distal colorectal cancers with an increase in right-sided lesions. In order to assess trends in the distribution of large bowel carcinoma at our hospital we reviewed the files of 1553 patients who presented with primary colorectal carcinoma over a(More)
Solitary desmoplastic trichoepitheliomas from a mother and two daughters were studied by conventional and electron microscopy. Differential diagnosis by conventional microscopy is briefly discussed. The lesions consisted of cords and nests of basaloid cells set in fibrotic stroma and confined to the dermis. In addition, each lesion contained horn cysts and(More)
