  • recurrence rates
  • Aggressive surgery (total ear canal ablation-lateral bulla osteotomy) has a significantly better outcome than conservative surgery because conservative surgery (such as a lateral ear wall resection) results in significantly higher local tumor recurrence rates (75% compared to 0%) and decreased survival times (9 months compared to 36 months).

  • Warning signs of malignant melanoma include change in the size, shape, color or elevation of a mole. (thetanningguru.com)
  • histological
  • Type II or Ceruminous Adenocarcinoma - has the same histological presentation as the previous one, in some cases shows pleomorphism and mitotic activity, infiltrative nature and involves soft tissue and bone with a high incidence of recurrence after partial surgical removal.

  • Generally pretreatment biopsy is indicated if the tumour type or histological grade would alter the type or extent of treatment, or if the result would change the owners willingness to proceed with definitive treatment. (zzcat.com)

  • behaviour
  • While therapeutic excisional biopsy has its indications, if it is performed without regard to tumour type or behaviour, then the optimal treatment course may be significantly compromised. (zzcat.com)
  • extent
