Prognostic significance of lymphatic spread in head and neck carcinomas: therapeutic implications.

A series of 618 patients with neck dissections were performed in 455 consecutively admitted patients with head and neck carcinomas at the Istituto Nazionale Tumori, Milan, from 1976 to 1978. Clinical and pathologic node factors were considered in an effort to correlate lymph node involvement with prognosis. Actuarial survival decreased with the increase in the size of nodes, although no significant difference was found for all categories and the prognosis was poor when nodes were greater than 5 cm and/or hypomobile (33%, 5-year survival). The presence of histologically proven neck metastases significantly reduces the 5-year survival, and the presence of distant metastases correlates directly with the pathologic staging of neck nodes.

In situ and very thin melanomas (< 0.75 mm) are similarly and commonly recognizable.

AIMS AND BACKGROUND: Recent data have suggested that cutaneous melanoma in situ can be clinically recognized in most cases by its features, which resemble those of early invasive melanoma. The aim of the study was to verify whether the diagnostic sensitivity of melanoma in situ is actually equivalent to that of early invasive melanoma. METHODS: We retrospectively reviewed the clinical diagnosis of 274 consecutive cutaneous melanoma < 0.75 mm thick. The series consisted of 84 in situ and 190 invasive lesions. RESULTS: The clinical diagnosis of melanoma was performed in 62% (52/84) of cases of in situ melanoma and in 68% (130/190) of the cases of invasive melanoma. The differences were not statistically significant. CONCLUSIONS: Our results show that cutaneous melanoma can be clinically diagnosed at a very early stage. In situ and very thin melanomas (< 0.75 mm) are similarly recognizable.

Melanoma of the external ear.

AIMS AND BACKGROUND: Melanoma of the external ear is a rare disease, and its management is controversial. To address this problem, we reviewed the data concerning the patients observed at our Institution. METHODS: We retrospectively reviewed the clinical records of the 20 patients bearing primary ear melanoma observed over a period of about 20 years at the Istituto Nazionale Tumori of Milan. RESULTS: Initial evaluation of the patients revealed 7 stage I, 12 stage II and 1 stage III. The thickness of the tumors varied from 0.39 to 6.62 mm. Fourteen patients underwent a wedge resection of the skin and cartilage with primary closure, and 6 patients had a partial amputation of the ear. In 8 cases the section was performed at about 1 cm from the border of the tumor, in 6 cases at about 0.5 cm, and in 6 cases at more than 1 cm. The average follow-up was 57 months (range, 1-18 years). Since there was no local recurrence, it could not be related to type and extent of the local resection performed. In contrast, the development of metastases was related to tumor thickness. CONCLUSIONS: A conservative excision with margins of 1 cm can be a safe procedure for invasive ear melanoma, irrespective of tumor thickness. Like melanomas of other sites, the prognosis is linked to the thickness of the tumor.

[Impact of sentinel lymph node biopsy on the treatment of melanoma].

In the National Cancer Institute and S Pio X Hospital series we registered 981 patients with primary cutaneous melanoma and no evidence of clinically detectable regional node metastases underwent sentinel node (SN) dissection to microscopically define the tumor status of the regional lymph nodes. In 62.2% of cases, only one SN was detected; 26.4% of patients had two SNs and 11.4% had three or more SNs. A positive SNB was demonstrated in 18.1%. Analysis of survival indicated that the tumor status of the nodes was the most important prognostic factor. Breslow's thickness had a significant impact on survival in tumors of 4 mm or thicker, and ulceration dropped to a borderline significant P-value. To assess the tumor burden in positive SNB, all slides (148 SN pos) were reviewed. Twenty per cent of these patients had evidence of metastasis in other nodes. Of the remaining 80% with a single tumor-involved SN, 62% had a single metastatic deposit. Preliminary data from this study indicate that several subgroups may be identified among patients with 1 positive node, but adequate analysis of survival requires a larger number of patients and a multicentric study.
