Pathologic Features

Purpose The aim of this study was to assess the independent prognostic value of primary tumor mitotic rate compared with other clinical and pathologic features of stages I and II melanoma. Methods From the American Joint Committee on Cancer (AJCC) melanoma staging database, information was extracted for 13,296 patients with stages I and II disease who had mitotic rate data available. Results Survival times declined as mitotic rate increased. Ten-year survival ranged from 93% for patients whose tumors had 0 mitosis/mm2 to 48% for those with ≥ 20/mm2 (P < .001). Mean number of mitoses/mm2 increased as the primary melanomas became thicker (1.0 for melanomas ≤ 1 mm, 3.5 for 1.01 to 2.0 mm, 7.3 for 3.01 to 4.0 mm, and 9.6 for > 8 mm). Ulceration was also associated with a higher mitotic rate; 59% of ulcerated melanomas had ≥ 5 mitoses/mm2 compared with 16% of nonulcerated melanomas (P < .001). In a multivariate analysis of 10,233 patients, the independent predictive factors for survival in order of statistical significance were as follows: tumor thickness (χ2 = 104.9; P < .001), mitotic rate (χ2 = 67.0; P < .001), patient age (χ2 = 48.2; P < .001), ulceration (χ2 = 46.4; P < .001), anatomic site (χ2 = 34.6; P < .001), and patient sex (χ2 = 33.9; P < .001). Clark level of invasion was not an independent predictor of survival (χ2 = 3.2; P = .37). Conclusion A high mitotic rate in a primary melanoma is associated with a lower survival probability. Among the independent predictors of melanoma-specific survival, mitotic rate was the strongest prognostic factor after tumor thickness.

Testicular neuroendocrine tumors (NET) or carcinoid tumors are rare neoplasms which represent 1% of all testicular tumors and can be divided into 3 subgroups: pure primary testicular NET, primary testicular NET associated with a teratoma, and NET metastases to the testis. We report an unusual presentation of a primary testicular neuroendocrine tumor in a 39-year-old male who presented after a physical altercation during a soccer game. Histology showed a diffuse infiltrating tumor with extensive involvement of the tunica albuginea and tunica vaginalis. Immunohistochemical expression of CD56, synaptophysin, and chromogranin A was strongly positive in the tumor cells. Foci of tumor cell necrosis and occasional mitotic figures as well as extensive lymph-vascular invasion were also identified. A review of the literature reveals differing opinions on the prognostic significance of primary tumor size, mitotic index, tumor necrosis, and nuclear atypia. In our patient, the increased mitotic rate (3–5 mitotic figures per 10 hpf and a Ki-67 index of 5%), foci of necrosis, and mild to moderate nuclear atypia warranted a diagnosis of neuroendocrine tumor grade 2, formerly atypical carcinoid. Long term surveillance in these patients is essential as metastasis occurs in up to 15% of cases. At the 6-month followup, the patient remains symptom free.

9004 Background: Cancer-testis antigens (CTAg) are epigenetically regulated molecules expressed in many cancers including melanoma. Although functional studies are limited, they are often immunogenic making them attractive targets for immunotherapy. In normal tissues expression is restricted to germ cells and a small range of other tissues such as trophoblast. Previous studies have shown that CTAg expression increases with disease progression. We investigated whether the expression of three CTAgs, against which vaccines have been developed, may have prognostic significance in early stage melanoma. Methods: 233 AJCC Stage II melanomas were analyzed for expression of MAGE-A1, MAGE-A4 and NY-ESO-1 by immunohistochemistry. The relationship between CTAg expression, clinico-pathological features and relapse free survival (RFS) from initial diagnosis were correlated. Mutivariate analysis using known prognostic factors and CT Ag expression in the model were used to calculate hazard ratios. Results: All three CTAg were significantly co-expressed with each other (P=0.0001). RFS was reduced if tumors expressed any of these CTAgs (CTAg+ve). Median RFS for patients with CTAg+ve tumors was 45m versus 72m for those with CTAg-ve tumors (P=0.008, logrank test). Univariate analysis demonstrated that the impact of CTAg expression on RFS was comparable in magnitude to ulceration, Breslow thickness and mitotic rate, currently accepted prognostic factors. Multivariate analysis demonstrated CTAg expression, ulceration and thickness but not mitotic rate were independently associated with poorer RFS ( Table ). Conclusions: CTAg expression in cutaneous primary melanoma has impact on prognosis comparable to Breslow thickness ulceration and mitotic rate. Further study into their function and the impact of clinical targeting is warranted. [Table: see text] No significant financial relationships to disclose.
