Is a Wider Margin (2 cm vs. 1 cm) for a 1.01–2.0 mm Melanoma Necessary?

2-cm versus 4-cm surgical excision margins for primary cutaneous melanoma thicker than 2 mm: a randomised, multicentre trial.

BACKGROUND Optimum surgical resection margins for patients with clinical stage IIA-C cutaneous melanoma thicker than 2 mm are controversial. The aim of the study was to test whether survival was different for a wide local excision margin of 2 cm compared with a 4-cm excision margin. METHODS We undertook a randomised controlled trial in nine European centres. Patients with cutaneous melanoma t...

Surgical margins for melanoma: is 2 cm too much?

Final Report: ECE 892(851) The CM-1, CM-2, and CM-5: A Comparative Study

Sufficiency and safety of 2-cm excision margin for stage IIA through stage IIC cutaneous melanoma.

Question: In patients with clinical stage IIA through IIC cutaneous melanoma thicker than 2 mm, is survival different for a 2-cm local excision margin compared with a 4-cm excision margin? Design: Randomized controlled trial. The trial was not masked at any stage. Setting: Multicenter trial in 53 hospitals in 9 European centers in Sweden, Denmark, Estonia, and Norway. Patients: Patients 75 year...

2 Overview of the CM - 2 and CM - 5 Computers

This paper presents a preliminary experimental study of the performance of basic sparse matrix computations on the CM-200 and the CM-5. We concentrate on examining various ways of performing general sparse matrix-vector operations and the basic primitives on which these are based. We compare various data structures for storing sparse matrices and their corresponding matrix – vector operations. ...
