Uveal melanoma

aka Ocular melanoma, Choroidal melanoma

A melanoma inside the eye that is biologically unrelated to skin melanoma: different mutations, no response to standard immunotherapy, and a tendency to spread to the liver years later. Tebentafusp is the first drug ever to extend survival in the metastatic disease.

Uveal melanoma arises from melanocytes of the choroid, ciliary body or iris and is driven by GNAQ/GNA11 (or CYSLTR2/PLCB4) mutations activating Gαq signalling, with metastatic risk set by BAP1 loss and monosomy 3 (gene-expression class 2, PRAME expression) versus SF3B1 and EIF1AX mutations (lower risk). The primary tumour is controlled by plaque brachytherapy or proton beam in most cases (COMS showed equivalence to enucleation), but about half of patients relapse, typically in the liver, with a median survival historically under a year.

Unlike cutaneous melanoma, the tumour mutational burden is low and checkpoint inhibitors give response rates around 5%. Tebentafusp, a gp100×CD3 ImmTAC restricted to HLA-A*02:01, was the first therapy to improve overall survival in metastatic uveal melanoma (IMCgp100-202, 2021; approved 2022). Liver-directed therapy (percutaneous hepatic perfusion with melphalan, approved 2023 as Hepzato; radioembolisation; resection) controls hepatic disease. Darovasertib (PKC inhibitor) with crizotinib is in phase 2/3 in metastatic and neoadjuvant settings.

State of the art today

  • Liver-directed therapy has a randomised trial (FOCUS) behind percutaneous hepatic perfusion.
  • Gene-expression profiling reliably separates patients who will and will not metastasise, but there is still no adjuvant therapy that helps them.
  • Gαq-pathway inhibition (darovasertib ± crizotinib) is the leading targeted strategy.
Show survival figures (1)

Averages across everyone diagnosed, often years ago. Your stage, subtype, age, fitness and the treatment you receive matter more than the average, and the numbers are improving quickly.

  • Tebentafusp is the first TCR-based bispecific approved in any cancer and the first drug to improve survival in metastatic uveal melanoma.
Who it affects

About 5-7 per million per year (the most common primary eye cancer in adults); half of patients eventually develop metastases, almost always in the liver.

Standard of care

4top
Primary tumour

Plaque brachytherapy (I-125 or Ru-106) or proton beam radiotherapy for most; enucleation for large tumours; prognostic biopsy for GEP/chromosome 3.

Surveillance

Risk-adapted liver imaging (MRI/ultrasound) every 6-12 months for high-risk GEP class 2 / monosomy 3; no proven adjuvant therapy.

Metastatic, HLA-A*02:01-positive

Tebentafusp weekly (OS 21.7 vs 16.0 months vs investigator's choice); manage cytokine release and rash.

NCCN · Category 1ESMO-MCBS · 4
Metastatic, HLA-A*02:01-negative or liver-dominant

Percutaneous hepatic perfusion with melphalan (FOCUS trial; approved 2023), radioembolisation, hepatic resection; ipilimumab-nivolumab (~15% response); clinical trials (darovasertib-crizotinib).

Open problems

  • Half of patients metastasise with no adjuvant therapy despite accurate prediction.
  • Tebentafusp only for HLA-A*02:01 (about 45% of white patients, fewer elsewhere) and gives few objective responses despite OS benefit.
  • Liver-tropic metastasis biology poorly understood.
  • Vision-preserving local therapy still causes radiation retinopathy.

Questions to ask your oncologist about Uveal melanoma

Generated from this cancer's standard of care, biomarkers, and pipeline · 15 questions

Newly diagnosed

  1. What is my exact diagnosis, stage, and grade, and which tests established them?
    Why: Everything else follows from an accurate stage and subtype.
  2. Which biomarkers have been tested on my tumour (for example GNAQ / GNA11 mutations, BAP1 loss and monosomy 3, SF3B1, EIF1AX, Gene-expression profileand PRAME, HLA-A*02:01), and what were the results?
    Why: These results decide eligibility for targeted therapy, immunotherapy, and trials.
  3. Which subtype is my cancer, and does that change the recommended treatment?
    Why: Recognised subtypes for this cancer include Choroidal melanoma, Ciliary body melanoma, Iris melanoma.
  4. Is germline (inherited) genetic testing recommended for me or my family?
    Why: Inherited variants can change treatment and matter for relatives.

Primary tumour

  1. For my situation (primary tumour), which of the standard options do you recommend and why?
    Why: Guideline options include: Plaque brachytherapy (I-125 or Ru-106) or proton beam radiotherapy for most; enucleation for large tumours; prognostic biopsy for GEP/chromosome 3.

Surveillance

  1. For my situation (surveillance), which of the standard options do you recommend and why?
    Why: Guideline options include: Risk-adapted liver imaging (MRI/ultrasound) every 6-12 months for high-risk GEP class 2 / monosomy 3; no proven adjuvant therapy.

Metastatic, HLA-A*02:01-positive

  1. For my situation (metastatic, hla-a*02:01-positive), which of the standard options do you recommend and why?
    Why: Guideline options include: Tebentafusp weekly (OS 21.7 vs 16.0 months vs investigator's choice); manage cytokine release and rash.
  2. Am I a candidate for Tebentafusp, and what side effects should I expect?
    Why: Knowing the expected toxicities helps you plan work, family, and supportive care.

Metastatic, HLA-A*02:01-negative or liver-dominant

  1. For my situation (metastatic, hla-a*02:01-negative or liver-dominant), which of the standard options do you recommend and why?
    Why: Guideline options include: Percutaneous hepatic perfusion with melphalan (FOCUS trial; approved 2023), radioembolisation, hepatic resection; ipilimumab-nivolumab (~15% response); clinical trials (darovasertib-crizotinib).
  2. Am I a candidate for Melphalan (including hepatic delivery system), Ipilimumab, Nivolumab, and what side effects should I expect?
    Why: Knowing the expected toxicities helps you plan work, family, and supportive care.

Any stage

  1. Are there clinical trials I could join, for example of Tebentafusp, Percutaneous hepatic perfusion (chemosaturation), Brenetafusp?
    Why: Trials are how the next standard of care is set; asking early keeps options open.
  2. Would a second opinion at a high-volume centre change anything, and can you help arrange it?
    Why: Rare or high-stakes decisions benefit from a centre that treats many similar patients.
  3. What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
    Why: Supportive care improves quality of life and helps patients complete treatment.
  4. I read that “Half of patients metastasise with no adjuvant therapy despite accurate prediction”. How does that affect my plan?
    Why: Open problems are where trials and second opinions matter most.
  5. I read that “Tebentafusp only for HLA-A*02:01 (about 45% of white patients, fewer elsewhere) and gives few objective responses despite OS benefit”. How does that affect my plan?
    Why: Open problems are where trials and second opinions matter most.
