Mucosal melanoma: the decisions you may face

5 treatment settings, 4 with more than one named option. Each section lays out the options the standard of care names, what each is for, the trials behind them with their recorded results, the side effects and cautions on record, and questions to ask. Built from the cancer page's standard-of-care rows; nothing here is advice for your case.

Early / localised

Localised disease

One path named

Wide surgical excision with the least morbid operation that clears margins; postoperative radiotherapy for head and neck and anorectal primaries to improve local control.

The path, in plain words

IMRT and IGRT shape the radiation beam to the tumour's outline from multiple angles and check the patient's position with a scan before every session, so surrounding organs receive less dose. Fewer, larger doses are now standard in breast and prostate cancer, but a low-dose bath still spreads across normal tissue.

  • Conformal dose, fewer side effects
  • Hypofractionation saves visits
Also referenced:Wide local excision
The evidence behind it

No trial record is attached to this row yet. The trials tab lists what is recruiting and the landmark trials for this cancer.

The main trade-offs on record
  • Low-dose bath to normal tissue
  • Motion management
Questions to ask about this decision
  1. Is IMRT / IGRT (modern external beam) the only reasonable path for me, or is there a trial, a different sequence or a wait-and-see option?
    Why: A single standard does not mean a single choice; timing and trials are decisions too.
  2. What is each option trying to achieve: cure, long control, or relief of symptoms, and over what time?
    Why: The aim shapes how much side effect and disruption is worth accepting.
  3. What happens if I delay, or decline this step for now? Is the decision reversible?
    Why: Some decisions can wait for a second opinion or a trial slot; others cannot. Knowing which is part of the choice.
  4. Does your recommendation follow the current guideline (NCCN Guidelines: Melanoma: Cutaneous), and if it departs from it, why?
    Why: Departures from guidelines are sometimes right for an individual; they should be explained.
  5. For my situation (localised disease), which of the standard options do you recommend and why?
    Why: Guideline options include: Wide surgical excision with the least morbid operation that clears margins; postoperative radiotherapy for head and neck and anorectal primaries to improve local control.

Anti-PD-1 antibody as for cutaneous stage III disease by extrapolation; temozolomide-cisplatin chemotherapy is an option in China on a randomised trial.

The options, in plain words

Nivolumab was the second PD-1 blocker and is often combined with ipilimumab. Long-term data show about half of advanced melanoma patients alive at 10 years on the combination.

Pembrolizumab is a PD-1 blocking antibody approved in more than 40 settings, from melanoma and lung cancer to the first tumour-agnostic approval for mismatch-repair-deficient tumours in 2017, and before and after surgery in triple-negative breast cancer. A subcutaneous form arrived in 2025, and it is the backbone partner for ADCs and personalised neoantigen vaccines.

The only chemotherapy proven to extend life in glioblastoma, given during and after radiation. It works best when the tumour has switched off a repair gene called MGMT.

Cisplatin is the original platinum chemotherapy, discovered by accident in 1965; it cures testicular cancer and makes radiation work better in cervical and head and neck cancer.

Questions to ask about this decision
  1. Between Nivolumab, Pembrolizumab, Temozolomide and the other options, which do you recommend for me, and what about my case would make you choose differently?
    Why: Guidelines list several reasonable options; the choice turns on details of your tumour, your health and your priorities.
  2. What is each option trying to achieve: cure, long control, or relief of symptoms, and over what time?
    Why: The aim shapes how much side effect and disruption is worth accepting.
  3. Which side effects of Nivolumab or Pembrolizumab are most likely for me, which are reversible, and which would make us stop?
    Why: The recorded rates below come from labels and trials; your own risk depends on dose, other medicines and your health.
  4. What happens if I delay, or decline this step for now? Is the decision reversible?
    Why: Some decisions can wait for a second opinion or a trial slot; others cannot. Knowing which is part of the choice.
  5. Does your recommendation follow the current guideline (NCCN Guidelines: Melanoma: Cutaneous), and if it departs from it, why?
    Why: Departures from guidelines are sometimes right for an individual; they should be explained.
  6. For my situation (adjuvant), which of the standard options do you recommend and why?
    Why: Guideline options include: Anti-PD-1 antibody as for cutaneous stage III disease by extrapolation; temozolomide-cisplatin chemotherapy is an option in China on a randomised trial.
  7. Am I a candidate for Nivolumab, Pembrolizumab, Temozolomide or related drugs, and what side effects should I expect?
    Why: Knowing the expected toxicities helps you plan work, family, and supportive care.

Nivolumab plus ipilimumab (higher response than nivolumab alone in the pooled analysis) or anti-PD-1 monotherapy; toripalimab with axitinib in China.

The options, in plain words

Nivolumab was the second PD-1 blocker and is often combined with ipilimumab. Long-term data show about half of advanced melanoma patients alive at 10 years on the combination.

Ipilimumab was the first checkpoint inhibitor (2011), and proved the immune system could be unleashed against cancer.

Pembrolizumab is a PD-1 blocking antibody approved in more than 40 settings, from melanoma and lung cancer to the first tumour-agnostic approval for mismatch-repair-deficient tumours in 2017, and before and after surgery in triple-negative breast cancer. A subcutaneous form arrived in 2025, and it is the backbone partner for ADCs and personalised neoantigen vaccines.

A Chinese-developed PD-1 blocker that became the first immunotherapy approved in the US for nasopharyngeal cancer.

Axitinib is a selective VEGF-receptor pill, now given mainly with pembrolizumab or avelumab as first-line kidney cancer treatment.

Other settings

KIT-mutant disease

Imatinib for exon 11 or 13 mutations after or alongside immunotherapy; nilotinib is an alternative.

The options, in plain words

The drug that started the targeted therapy era in 2001, turning chronic myeloid leukaemia into a manageable condition with near-normal life expectancy.

Nilotinib is a second-generation CML pill that produces deeper responses faster than imatinib, at the cost of cardiovascular and metabolic side effects.
