[Precancerous skin lesions in the aged (author's transl)].

The term "precancerous" needs a new definition since it includes still malignant diseases like Morbus Paget of the nipple, Morbus Bowen and Erythroplasie Queyrat. The degree of malignancy of these disorders is analyzed. Precancerous conditions in the sense of benignant disorders which necessarily develop into malignant tumors are Melanosis circumscripta praeblastomatosa Dubreuilh and actinic keratoses. Potential precanceroses may be X-ray-atrophy, Leukoplakia and oral papillomatosis. Some actinic, chemic and cytostatic cancerogens are mentioned. Reference is made to the diagnosis, differential diagnosis, prognosis and treatment of precancerous skin lesions. The problem of potential malignancy of nevi is considered in detail. Prevention of cancer needs regular careful clinical control of skin and mucous membranes at least after the 50th year of life.

Sapphire probe laser surgery for localized carcinoma of the penis.

Cancer of the penis is an uncommon disease in the western world, but it causes significant morbidity and mortality worldwide. Discussions have tended to centre around issues of local tumor control and the functional status of the penis after treatment. Since November 1982 we have treated localized squamous cell penile cancer (Tis, T1 and T2, Classification UICC, Geneva 1978) with the Nd-YAG laser. Sixteen patients (3Tis, 5T1 and 8T2 tumors) are included in this study with a follow-up of 4 to 36 months (mean 17 months). Eight out of 16 patients were treated with the sapphire probe exclusively, the other eight patients by scalpel excision followed by laser irradiation. No recurrent tumor was observed in 13 patients, one patient developed a recurrence at a non-treated part of the glans penis after 14 months, one patient showed Tis after 5 months near the treated side and in one patient an incomplete laser resection was followed by partial penectomy after 1 month. Sapphire probe laser excision is a safe procedure leading to a good cosmetic aspect with maintenance of the functional integrity of the penis.

Chemoprevention of head and neck cancer. Potential use of retinoids.

Research on retinoid treatment of neoplastic lesions will ultimately determine the long-term effect of these substances on cancer development. However, until specific indications are firmly established through clinical trials, retinoid compounds cannot be routinely recommended.
