Indications for operation in laryngeal cancer.

Improvements in the surgical treatment of laryngeal cancer by combined laryngectomy and radical neck dissection have given new importance to selection of the mode of treatment for various stages of disease at that site. To cast light on the subject, the cases of 63 patients with cancer of the larynx were reviewed. Twenty-one of them were operated on for recurrence after radiation therapy; and 42 were treated surgically at the outset, 36 of them having combined laryngectomy and radical neck dissection. In almost 80 per cent of the patients the lesion was extrinsic. In the entire series, 51 patients had combined operations, and in 41 of them the cervical lymph nodes were positive for metastasis. Reports in the literature also make note of a very high incidence of cervical node metastasis not only in cases of extrinsic cancer, but also in those in which the lesion is intrinsic. Because of the frequency of cervical node spread, and its occult nature, choice between radiation and surgical operation must be made after candid, critical appraisal of the individual condition in each patient.

Orbital and periorbital tumors. Indications for exenteration.

The anatomical location of the orbit, its relationship to surrounding structures and the vital concern to preserve sight, create special problems in the treatment of orbital and periorbital tumors.Specific diagnosis of orbital tumors can be made only by biopsy. Frozen section technique is very helpful when available. Roentgenographic visualization of the orbital bones is a valuable adjunctive method of determining the extent and type of tumor. The three most common forms of lacrymal gland tumors are benign "mixed tumors," adenoid cystic carcinomas (cylindromas), and adenocarcinomas.A method of therapy for the treatment of orbital and periorbital tumors is described and the indications for exenteration are discussed.

The surgical treatment of melanoma.

Some melanomas arise from compound and junctional nevi. Since there is a relatively high incidence of malignant diseases on the soles of the feet and the genitalia, routine removal of nevi developing in those areas is recommended."Juvenile melanomas" are active, cellular nevi occurring in prepubertal children. The clinical course is probably benign. The tenet of excision and dissection in continuity where feasible of the primary melanoma and the regional lymph nodes is reemphasized. When continuous dissection is not possible, regional node dissection is recommended as a separate procedure. Major amputations for melanomas of the extremities are not recommended for the usual case.
