The value of staging and serial follow-up investigations in patients with completely resected, primary, cutaneous malignant melanoma.
The purpose of this study was to determine the value of staging and serial follow-up investigations in newly diagnosed patients with completely excised primary cutaneous malignant melanoma. We reviewed the records of the 393 patients with completely excised primary malignant melanoma who were referred to the Ontario Cancer Institute and the Toronto-Bayview Regional Cancer Centre between 1 January 1978 and 31 March 1982. Initial investigations included history and physical examination in all 393 patients, complete blood count (199 patients), liver function tests (198 patients), urinary melanins (159 patients), chest X-rays (345 patients), whole lung tomography (182 patients), radionuclide liver-spleen scans (207 patients), and bone scans (116 patients), bipedal lymphangiograms (78 patients), CT scans of the chest (59 patients), and CT brain scans (51 patients). The clinical stage of ten patients was changed as a result of history and physical examination or lymphangiogram. All other investigations failed to detect metastatic melanoma. Follow-up investigations included history and physical examinations, complete blood counts, liver function tests, radionuclide liver spleen and bone scans. History and physical examinations, chest X-rays and patients' awareness of abnormalities were responsible for detection of subsequent melanoma recurrences. All other tests failed to identify metastatic melanoma at the time of its occurrence. Therefore, we recommend that initial staging investigations be limited to history and physical examination with clinical photographs, and baseline chest X-ray. We recommend that subsequent follow-up include only history and physical examinations and chest X-rays.
