Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Topical application of diphencyprone cream to cutaneous metastases.

The optimal diphencyprone dose is determined in each patient as the concentration causing adequate but not excessive contact dermatitis. The concentration may range from 0.0001% to 2%, mixed in aqueous cream. The cream is applied once per week, for 24 to 48 hours depending on intensity of response.

If there has been no response in 3 months, the treatment will be ceased. If there is response, the treatment can be continued indefinitely until refractory disease recurrence/progression. Usually, patients will require ~1 to 3 months to achieve a response. Ongoing treatment (ie, cream applied each week at home by patients) will then be offered to any patients who request it, with the aim of preventing further recurrence.
