title: [Diagnostic modalities of visceral metastases during follow-up of patients with stage I-II melanoma].
abstract: BACKGROUND
  Although not recommended in France at the consensus conference of 1994, routine monitoring of patients with stage I melanoma using imaging techniques is commonly carried out. The aim of this retrospective regional study was to define methods for diagnosing transition to the metastatic stage of melanoma.
  
  
  METHODS
  This was a retrospective study based on questionnaires among dermatologists in the Champagne-Ardenne and southern Aisne regions of France. For each patient with stage IV melanoma between 1987 and 2002, data were collected concerning the primary melanoma (date of diagnosis, clinical picture, histopathologic features), stage of melanoma prior to diagnosis of metastatic melanoma and characteristics of the metastases (date, number, type, site and modern discovery: clinical signs or routine imaging).
  
  
  RESULTS
  One hundred and eight patients (63 men and 45 women; mean age: 59 years) were included in the study. The predominant site of the primary melanoma was the trunk for men (n=31) and the lower limbs for women (n=16) and the mean Breslow index was 4.31 mm (SD=4.22), with histologic ulceration being present in 40% of cases. The mean time to transition to stage IV after discovery of the primary tumour was 2.8 years (SD=2.95). The modes of discovery of metastases comprised clinical examination (functional signs or physical examination) in 58 cases and routine imaging in 50 cases, with no significant differences based on whether patients were initially in stage I-II or in stage III.
  
  
  CONCLUSIONS
  This study shows that over half of patients progressing to stage IV melanoma had a suspicious sign or clinical symptom, once again highlighting the importance of clinical monitoring. In contrast, many organ metastases, particularly pulmonary, were discovered by routine imaging examinations carried out as part of patient follow-up, although this is not currently recommended practice in France.
  
  
  CONCLUSIONS
  The role of powerful imaging examinations such as scans, with constantly improving resolution, still remains to be defined in the follow-up of patients with stage I-II melanoma, and further prospective studies are thus required.
