Side effects and results of isolated hyperthermic extremity perfusion in malignant melanoma at the University of Cologne were reviewed: Severe local and systemic side effects (WHO grade III, IV) occurred in 3%, 5-year survival rates were 100% in TNM stage I patients (n = 27), 88.7% in TNM stage II patients (n = 123), 46.4% in TNM stage III patients (n = 169) and 36.3% in TNM stage IV patients (n = 22). 5-year recurrence free survival rates were 100% in TNM stage I, 73.4% in TNM stage II, 20.8% in TNM stage III and in TNM stage IV 9.1%. Indication for extremity perfusion remains locoregional recurrent disease.

We abide by a rule of the UICC system of cutaneous malignant melanoma and non-melanoma skin cancer. Assignment of pT stage for melanoma requires accurate measurement of pathological findings. On the other hand, T classification of SCC is decided only by measurement of size. We introduced the UICC TNM staging systems and compared the 5-year survival rate of our cases with the statistical data of the Japanese Society for Skin Cancer.

A review of the latest literature concerning the present level of radiation therapy in veterinary medicine is given. In a general section physico-technical as well as biological fundamentals are discussed. In the special part of the paper indications for a radiation therapy of dogs, cats and horses are stated. In this respect the basis for a decision is the TNM-classification into different clinical stages according to the directions of the WHO. Tumors of the hemolymphatic system are very responsive to radiation therapy. While epithelial tumors are sensitive, tumors arising from the mesenchymal tissues react less sensitive. Melanoma and osteosarcoma seem to be resistant to radiation therapy. Besides this, radiation therapy is often questioned by the tolerance of the normal tissue.

Clinical data from 369 patients with clinical stage I cutaneous malignant melanoma treated in Kuopio University Hospital district between 1974 and 1989 with a mean follow-up of 6.4 years were analysed. Clinical parameters, histology, DNA index, S-phase fraction (SPF) and mitotic indices [mitotic activity index (MAI) and volume-corrected mitotic index (M/V index)] were correlated with the outcome of the disease to establish their value as predictors of stage I cutaneous malignant melanoma. In univariate survival analyses, bleeding, gender, tumour thickness, level of invasion according to Clark, TNM category, MAI, M/V index and SPF were the most significant predictors of recurrence-free (RFS) and overall survival. In Cox's multivariate analysis, tumour thickness (P = 0.0021), bleeding (P = 0.0106) and M/V index (P = 0.0058) predicted poor RFS in the 259 patients available for the analysis. Poor overall survival was predicted by MAI (P = 0.0002), bleeding (P = 0.004), SPF (P = 0.009) and male gender (P = 0.034). The present results indicate that mitotic activity index (MAI), volume-corrected mitotic index (M/V index) and S-phase fraction (SPF) are important prognostic factors in addition to the well-established Breslow thickness in stage I cutaneous malignant melanoma.

The present TNM classification of ophthalmic malignant tumors (lid cancer, malignant melanoma of the lid, conjunctival cancer, conjunctival malignant melanoma, uveal malignant melanoma, retinoblastoma, orbital sarcoma and lacrimal gland cancer) has been explained according to the UICC in a book edited by M. H. Harmer and J. A. Oosterhuis. Five studies concerning the difference in clinical results with and without a treatment were shown to confirm the meaning and importance of TNM classification of ophthalmic malignancies.

This study presents the data on incidence, TNM-classification and therapy outcome of 79 dogs with oropharyngeal tumors, which were admitted to the Clinic of Small Animals, Hannover School of Veterinary Medicine. 52 neoplasms were examined histologically. The most common tumors were malignant melanoma (n = 17), fibrosarcoma (n = 5), squamous cell carcinoma and peripheral odontogenic fibroma (n = 4). It could be determined that dogs treated by surgery, regardless of tumor type and type of surgery, had longer survival times than untreated dogs. With regard to survival time and the rate of local tumor recurrence, radical surgery (partial mandibulectomy/maxillectomy) led to good results in squamous cell carcinomas and invasive odontogenic tumors, but, keeping in mind the small number of cases, showed no advantage over conservative surgery in malignant melanomas, fibrosarcomas, neurofibrosarcomas and non invasive odontogenic tumors. It could be shown that the clinical staging of the patients was of prognostic relevance.

The expression of p21, p53 and proliferating cell nuclear antigen (PCNA) was analysed by immunohistochemistry in a consecutive series of 369 clinical stage I cutaneous malignant melanoma patients. Correlation of the detected expression levels with each other, with clinicopathological data and with melanoma survival were statistically evaluated. p21 expression was significantly associated with p53 and PCNA expression levels. In addition, high levels of p53 and PCNA were significantly interrelated. Tumour thickness, recurrent disease, high TNM category and older (> or = 55 years) age at diagnosis were inversely associated with p21 expression. Gender, bleeding, tumour thickness, Clark's level of invasion, TNM category and p53 index were all important predictors of both recurrence-free and overall survival of melanoma. In Cox's multivariate analysis including 164 patients with a complete set of data, only high tumour thickness and bleeding predicted poor recurrence-free survival (P = 0.0042 and 0.0087 respectively) or overall survival (P = 0.0147 and 0.0033 respectively). Even though elevated p21 expression may be associated with more favourable prognosis in clinical stage I cutaneous melanoma, our results suggest that cell cycle regulatory effects of p21 can be overcome by some other and stronger, partly yet unknown, mechanisms.

The Melanoma Staging Committee of the AJCC has proposed major revisions of the melanoma TNM and stage grouping criteria. The committee members represent most of the major cooperative groups and cancer centers worldwide with a special interest in melanoma; the committee also collectively has had clinical experience with over 40,000 patients. The new staging system better reflects independent prognostic factors that are used in clinical trials and in reporting the outcomes of various melanoma treatment modalities. Major revisions include 1) melanoma thickness and ulceration, but not level of invasion, to be used in the T classification; 2) the number of metastatic lymph nodes, rather than their gross dimensions, the delineation of microscopic versus macroscopic lymph node metastases, and presence of ulceration of the primary melanoma to be used in the N classification; 3) the site of distant metastases and the presence of elevated serum LDH, to be used in the M classification; 4) an upstaging of all patients with Stage I,II, and III disease when a primary melanoma is ulcerated; 5) a merging of satellite metastases around a primary melanoma and in-transit metastases into a single staging entity that is grouped into Stage III disease; and 6) a new convention for defining clinical and pathologic staging so as to take into account the new staging information gained from intraoperative lymphatic mapping and sentinel lymph node biopsy. The AJC Melanoma Staging Committee invites comments and suggestions regarding this proposed staging system before a final recommendation is made.

The authors submit a review of histological findings and classification according to the TNM-classification of conjunctival tumours in patients under dispensary care at the First Ophthalmological Clinic of the Faculty Hospital and Medical Clinic of the Comenius University in Bratislava during a 10-year period (1989-1998). They included in the group 75 patients with clinically assessed conjunctival tumours (0.4% of the hospitalized patients). As to histological findings, 61 times (80.3%) a benign process was involved (naevus of the conjunctiva 12x) and 14x (19.7%) a malignant tumour, (7x times a primary malignant melanoma of the conjunctiva, 3x carcinoma). The authors recorded two relapses (one malignant melanoma of the conjunctiva, one melanoma penetrating into the orbit). The mean age of the patients was 47 years (from 1 to 82 years). In malignant melanoma of the conjunctiva stage T1 was detected in as many as 3/4 of the patients (6 times), whereby stage pT1, 2 was found in 7 patients. In carcinoma the authors did not detect stage T1, only stage T2 in 2 patients, T3 (pT3) in one patient.

The optimal follow-up strategy after completion of therapy for melanoma is not known. We evaluated the effect of TNM stage on the self-reported surveillance strategies employed by practicing plastic surgeons caring for otherwise healthy patients subjected to potentially curative treatment for cutaneous melanoma. Hypothetical patient profiles and a detailed questionnaire based on these profiles were mailed to a random sample (N=3,032) of the 4,320 members of the American Society of Plastic and Reconstructive Surgeons. The effect of TNM stage on the surveillance strategies chosen was analyzed by repeated-measures ANOVA. There were 1,142 responses to the 3,032 surveys; 395 were evaluable. Plastic surgeons often do not provide postoperative follow-up themselves; this was the most frequent reason for non-evaluability. Surveillance of patients after resection of melanoma relies most heavily on office visits, chest X-ray, CBC, and liver function tests. All other surveillance modalities are used infrequently. Most respondents modify their surveillance practices slightly according to the patient's initial TNM stage. Most commonly used modalities are employed significantly more frequently with increasing TNM stage. This effect persists through ten years of follow-up, but the differences across stages are tiny. We conclude that most plastic surgeons performing surveillance after potentially curative surgery in otherwise healthy patients with melanoma use similar follow-up strategies for patients of all TNM stages. These data permit the rational design of a controlled clinical trial of high-intensity vs. low-intensity follow-up.
