  • Ninety per cent of the mucosal melanoma patients had already received at least one prior treatment and 39% of them had received ipilimumab, a type of monoclonal antibody that is already used in the treatment of melanoma.[ecco-org.eu]
  • However, at the last follow-up 14 months after treatment initiation, the CT scans revealed progressive disease in the lung. For this reason, the treatment with imatinib was stopped.[karger.com]


  • It has a poorer prognosis than skin melanoma. It is not clear whether this is due to late diagnosis or the aggressiveness of the cancer. Ways to predict prognosis are needed.[medivizor.com]

  • Melanomas that arise from oral mucosa have a poor prognosis unless they are both discovered and treated early.[disabled-world.com]


  • The etiology of malignant melanoma and its rate of increase are complex. There are multiple factors that appear to play a role in the development of malignant melanoma, as well as their progression.[disabled-world.com]
  • Disease etiology remains unclear. Approximately one-third of oral cavity tumors are preceded by melanosis.[healio.com]
  • Etiologic factors Until now, the etiologic factors of mucosal melanomas have not been identified. Sun exposure, which is a well-known risk factor for cutaneous melanomas, seems to play no role in the pathogenesis of nonskin melanomas.[dovepress.com]
