TLDR
The depth of invasion was studied using the criteria for staging of Clark et al.2 to see if maximal cross-sectional area, thickness, stage of invasion, or a combination of these can be of value in assessing the prognosis of cutaneous melanoma.Abstract:
CuTANEous melanoma is a most unpredictable lesion. The marked variation in prognosis is probably a function of many variables, one of which is the size of the tumor. Though there is a roughly inverse relationship between the diameter of the lesion and survival,5 very small lesions have recurred or metastasized. One possible reason for the lack of reliability of tumor size in estimating prognosis may be that studies to date have considered size in only two diamensions and have neglected tumor volume. Two melanomas can have the same diameter but differ greatly in thickness because of variation in either depth of invasion or degree of protrusion from the surface of the skin or both. A recent study 2 has shown that prognosis correlates well with staging of the depth of invasion, but there have been no studies relating survival to tumor volume. To measure tumor volume it is necessary to know the surface area of the tumor, but in this retrospective study we only know the maximal diameters of the lesions. By measuring the maximal thickness of the lesions we can calculate the maximal crosssectional area, which should be roughly proportional to the volume of the tumor. The depth of invasion was also studied using the criteria for staging of Clark et al.2 to see if maximal cross-sectional area, thickness, stage of invasion, or a combination of these can be of value in assessing the prognosis of cutaneous melanoma. A total of 98 lesions were so studied.read more

TL;DR: Univariate analysis for overall survival of melanoma revealed that age at onset older than 55 years, male gender, ulceration of tumor, and thicker tumor have the tendency to poorer prognosis, but without significant differences.

TL;DR: The high accuracy of this technique in the preoperative staging of malignant melanoma would offer a basis for defining the surgical margins of ⩾ 0.76 mm thick lesions, while the limited accuracy of sonometry in thePreoperatively staging of thin melanoma ⩽ 0.75 mm has emerged by applying adequate statistical methods.

Objective histopathologic grading of cutaneous malignant melanomas by stereologic estimation of nuclear volume. Prediction of survival and disease-free period
TL;DR: It is concluded that Vv may be a powerful prognostic indicator in cutaneous melanomas, suitable for objective malignancy grading and needs further investigation in a larger and contemporary series of patients with malignant melanomas.

Survival among patients with clinical stage I cutaneous malignant melanoma diagnosed in Western Australia in 1975/1976 and 1980/1981.
TL;DR: Five‐year survival rates were slightly higher for patients with cutaneous malignant melanoma diagnosed in Western Australia in 1980/1981 than in those whose melanomas were diagnosed in 1975/1976, indicating that survival might be expected to continue to improve only gradually unless there is a sharp absolute decrease in the number of thick tumors diagnosed.

Long-Term Survival of Patients with Thin (T1) Cutaneous Melanomas: A Breslow Thickness Cut Point of 0.8 mm Separates Higher-Risk and Lower-Risk Tumors
TL;DR: A naturally occurring thickness cut point of 0.8 mm predicts higher or lower risk for patients with thin primary cutaneous melanomas, and a biologically-relevant difference in outcome above and below 0.

Some Methods for Strengthening the Common χ 2 Tests
TL;DR: In this article, the authors discuss two kinds of failure to make the best use of x2 tests which I have observed from time to time in reading reports of biological research, and propose a number of methods for strengthening or supplementing the most common uses of the ordinary x2 test.

The Histogenesis and Biologic Behavior of Primary Human Malignant Melanomas of the Skin
TL;DR: Evidence is presented suggesting that superficial spreading melanoma and lentigo maligna melanoma (Hutchinson9s melanotic freckle) show a long period of superficial growth, followed by the relatively rapid appearance of nodules or deeper invasion within the primary lesion.
