The relation between mortality from malignant melanoma and early detection in the Cancer Research Campaign Mole Watcher Study.

Between 1987 and 1989 the Cancer Research Campaign funded a health education programme for the early detection of cutaneous malignant melanoma in the general population in 6 health districts of England and 1 health board in Scotland (population of 3 million). The intervention was evaluated by studying its effects on annual and cumulative mortality rates for melanoma. Population-based data on mortality from melanoma were collected in the intervention areas, the health regions covering those areas, and 5 other health regions of England from 1981 to 1996. Deaths from melanoma in cases diagnosed after the start of the intervention were used to study cumulative mortality rates. The annual mortality rates for melanoma, 1981 to 1996, showed no significant difference in their trends between the intervention areas, and other areas of England and Wales. After adjustment for pre-intervention rates, there was also no significant reduction in cumulative mortality from melanoma in the intervention areas compared with the non-intervention areas: rate ratio 1.2 (95% Cl 0.9-1.7) in men, 0.9 (95% Cl 0.7-1.3) in females. The lack of a significant reduction in melanoma mortality associated with the intervention raises questions about this approach to early detection and emphasises the need for new strategies.

Dermatology day care treatment centres.

Day care treatment centres provide the best solution for the treatment of most patients with psoriasis. The centre is not only ideal for treatment but has other roles, such as education of patients and nurses. The specialist dermatology nurse is the key to success. Out patient treatment of psoriasis is less expensive than in patient treatment. The development of a treatment centre should be seen as an additional facility and not as a substitute for in patient beds.

Four-layer bandaging and healing rates of venous leg ulcers.

This paper reports the healing rates of venous leg ulcers in a community setting (Exeter and District Community Health Services NHS Trust) using the Charing Cross four-layer compression system. We report on 514 venous leg ulcers and show healing rates of 40% at 12 weeks, 50% at 17 weeks, 57% at 24 weeks and 80% predicted at 2 years. Patients were treated in one of 16 community leg ulcer clinics or in their homes. Nurses were allowed to use this system only after full training by the leg ulcer management service. Nurses had to prove their competence in leg ulcer assessment, Doppler measurement and the technique of four-layer compression. Even in patients whose leg ulcers did not heal, it was felt that the four-layer compression system was comfortable, convenient and cost effective with only weekly changes of bandages being necessary.

Problems with registration of cutaneous malignant melanoma in England.

The aim of the study was to assess the completeness and accuracy of cancer registration for cutaneous malignant melanoma. The study was conducted in seven health districts in England and one health board in Scotland from 1987 to 1989 with a total resident population of 3.6 million. Records from pigmented lesion clinics and pathology laboratories collected during the Cancer Research Campaign's health education programme to promote the early detection of melanoma were matched with cancer registrations from a total of five regional cancer registries. In England 74% out of a total of 642 cases of invasive malignant melanomas (ICD 172) and 44% out of a total of 155 in situ melanomas (ICD 232) had been registered compared with 96% and 100% respectively in Scotland. A significantly higher proportion of late-stage cases was found among registered than among non-registered cases in England (P < 0.001). In all registries the majority of superficial spreading in situ melanomas were miscoded as invasive cases. The annual incidence of invasive malignant melanoma in the English study areas was found to be seven per 100,000 in men and 11 per 100,000 in women, similar to that reported in Scotland. The registries are best at recording thick or late-stage melanomas. As the skin cancer target for Health of the Nation depends on monitoring trends in the incidence of malignant melanoma, future improved ascertainment of cases and changes in the type of cases being registered must be taken into account.

Cancer Research Campaign health education programme to promote the early detection of cutaneous malignant melanoma. I. Work-load and referral patterns.

From 1987 to 1989 a campaign to promote the early detection of cutaneous malignant melanoma was conducted in the areas of seven health authorities in England and Scotland (total population 3.6 million). Data were collected on 17,155 patients attending pigmented lesion clinics (PLCs) in each study area during the campaign. After a dramatic rise in PLC referral rates in the first month of the campaign the average monthly referral rate among the target population in the study period settled to an average of 13 per 10(5), a twofold increase compared with the pre-campaign period. Over 85% of patients at all PLCs were seen within 4 weeks of referral from their general practitioners. The melanoma to non-melanoma detection ratio was (1:33). The organization of future early detection initiatives needs careful review and planning, in order to improve their effectiveness in all sections of the population, and to enable health services to cope with the increased work-load.

Cancer Research Campaign health education programme to promote the early detection of cutaneous malignant melanoma. II. Characteristics and incidence of melanoma.

The effect on the detection and characteristics of melanoma, resulting from the Cancer Research Campaign's health education programme to promote the early detection of melanoma in the general population, was studied from 1987 to 1989. The seven study areas in England and Scotland yield a target population of 3.6 million. Data were collected from local clinic-based registers, pathology laboratories, and the cancer registries. The average annual incidence rates of melanoma were seven and 12 per 10(5) in males and females, respectively, age-standardized to England and Wales, 1988. These rates are similar to the national figures for Scotland, where there is a national melanoma register, but higher than those reported by the English and Welsh cancer registries. The incidence was significantly higher in females than males (P < 0.001), and increased with age. Fifty-three per cent and 65% of cases in males and females, respectively, were thin (Breslow thickness < or = 1.5 mm), similar to the national figures from Scotland. No significant decrease in the incidence of late-stage tumours was found in either sex as a result of the campaign. Because of difficulties with ascertainment of cases in England, the main evaluation will focus on future trends in mortality rates for melanoma.

Short-contact anthralin therapy for psoriasis using an aqueous cream formulation.

A pilot study of five patients was conducted using an aqueous anthralin cream (Drithocreme) and demonstrated that between twenty and forty minutes was an effective contact time to produce an improvement in induration of psoriatic plaques. In a further, bilateral controlled study, the anthralin cream was used to treat twenty patients with symmetrical chronic plaque psoriasis. The cream was applied to one side of the body overnight and then to the other side in the morning. Thirty minutes later it was washed off both sides in a bath or shower. The results indicated that both overnight and short-contact treatment were equally effective, and the short-contact treatment reduced staining and irritation.

Clinical evaluation of fenticonazole cream in cutaneous fungal infections: a comparison with miconazole cream.

A randomized, double-blind, parallel-group, multi-centre clinical trial was undertaken in 60 patients with dermatophytosis or pityriasis versicolor to compare topical 2% fenticonazole cream with topical 2% miconazole cream. Treatment, by twice-daily application, was for 4 weeks or until earlier complete resolution of disease. Assessment was by laboratory mycological investigation and regular clinical/symptomatic evaluation, both during and for 2 to 6 weeks after therapy. Fifty-three patients satisfactorily completed the trial, 28 of whom received fenticonazole and 25 miconazole. The groups were adequately well-matched. All assessment criteria showed fenticonazole to be at least as efficacious as miconazole, with no statistically significant differences between the two treatments. A number of assessment criteria, however, did show trends in favour of fenticonazole. Fenticonazole resulted in mycological findings becoming negative in 92%, i.e. all but 2 of 25 patients, by the end of treatment and a similar proportion (91%, 21 of 23 patients) remained mycologically negative 2 to 4 weeks after the end of therapy. With miconazole, only 79% (19 of 24 patients) became mycologically negative during treatment and this figure decreased further to 74% (14 of 19 patients) after therapy. Essentially similar results were seen for clinical assessments of erythema, itching and desquamation, these features being significantly and progressively eliminated or improved by both treatments in high proportions of patients during therapy, followed by little tendency to return after the cessation of therapy. Overall clinical assessments demonstrated statistically significant improvement during the second, third and fourth weeks of treatment with both drugs. Only 4 patients (two with each treatment) were reported as showing clinical deterioration at any stage during the trial, in all cases after the end of therapy. There were no reports of local or systemic adverse reactions to either drug, and laboratory screening investigations failed to reveal any signs of toxicity. These results indicate that a 4-week course of twice daily topical 2% fenticonazole cream is extremely well tolerated and is at least as efficacious as an equivalent regimen of 2% miconazole for the treatment of cutaneous dermatophytosis or pityriasis versicolor. Trends in the results suggest that fenticonazole may prove to be more efficacious than miconazole, particularly in relation to elimination of laboratory evidence of persistent fungal infection, which could be reflected in a lower incidence of subsequent relapse of the disease.
