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

Lymph node sonography versus palpation for detecting recurrent disease in patients with malignant melanoma
TL;DR: It is concluded that patients with a negative result by lymph node palpation do not need further sonography for verification, however, any suspect result by palpation should be additionally evaluated by lymph nodes sonography in order to rule in or out metastatic disease.

TL;DR: The term ‘local recurrence’ is unhelpful in the authors' attempts to understand the pathology of malignant melanoma, and the term ’local metastasis’ could replace it with benefit.

Sentinel lymph node biopsy has no benefit for patients with primary cutaneous melanoma metastatic to a lymph node: an assertion based on comprehensive, critical analysis: part II.
TL;DR: No surgeon, pathologist, or oncologist is a seer, diviner, or prophet when it comes to predicting accurately the outcome for a patient with metastatic melanoma; it is woefully substandard because it is without benefit.

Mitotic indices, anti-PCNA immunostaining, and AgNORs in thick cutaneous melanomas displaying paradoxical behaviour
TL;DR: Both AgNOR numbers and patterns failed to act as prognostic variables—indeed, AgNORs failed to correiate with the other proliferative indices, suggesting that their value as a marker of tumour growth is severely limited.

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.
