Question 1/5
Which of the following would you assess to establish an integrated molecular classification for your patient with endometrial cancer?

HER2, human epidermal growth factor receptor 2; MMR, mismatch repair; NTRK, neurotrophic tyrosine receptor kinase; POLE, polymerase epsilon.

The 2022 ESMO clinical practice guideline for endometrial cancer states that molecular classification is established by assessing POLE, p53 and MMR status. 

Abbreviations

ESMO, European Society for Medical Oncology; MMR, mismatch repair; POLE, polymerase epsilon. 

Reference

Oaknin A, et al. Ann Oncol. 2022;33:860–77.

Question 2/5
In the 2022 ESMO clinical practice guideline for endometrial cancer, which molecular characteristic is used to help select the most appropriate second-line treatment for patients with advanced/recurrent endometrial cancer?

ESMO, European Society for Medical Oncology; MMR, mismatch repair; PD-L1, programmed death-ligand 1; POLEmut, polymerase epsilon ultramutated.

The 2022 ESMO clinical practice guideline for endometrial cancer differentiates second-line treatment by the tumour MMR status.1 Approvals of second-line ICI therapies since the ESMO clinical practice guideline was published are also based on MMR status.2,3

Abbreviations

ESMO, European Society for Medical Oncology; ICI, immune checkpoint inhibitor; MMR, mismatch repair.

Question 3/5
You have a patient with MSS/pMMR advanced endometrial cancer that has recurred after first-line treatment with platinum-based chemotherapy. Based on current approvals and guidelines, what immunotherapy-based treatment would you consider for this patient’s next line of therapy?

MSS, microsatellite stable; pMMR, mismatch repair proficient.

Pembrolizumab plus lenvatinib is currently the only ICI-based treatment approved by the EMA and FDA for use in the second-line setting for patients with MSS/pMMR endometrial cancer,1–4 and is recommended in the ESMO guidelines.5 According to the 2022 ESMO clinical practice guideline for endometrial cancer, second-line ICI treatment options for patients with MSI-H/dMMR tumours are dostarlimab or pembrolizumab monotherapy, as well as pembrolizumab plus lenvatinib.5

Abbreviations

dMMR, MMR deficient; EMA, European Medical Association; ESMO, European Society for Medical Oncology; FDA, US Food and Drug Administration; ICI, immune checkpoint inhibitor; MMR, mismatch repair; MSI-H microsatellite instability-high; MSS, microsatellite stable; pMMR, MMR proficient.

Question 4/5
You have a patient with MSI-H/dMMR advanced endometrial cancer and you are discussing the possibility of starting treatment with dostarlimab plus carboplatin/paclitaxel. They ask you for more information about the side effects of this combination. What do you tell them?

dMMR, mismatch repair deficient; MSI-H, microsatellite instability-high.

ICIs have a different side effect profile compared with chemotherapy and irAEs can affect any organ system.1 irAEs can occur at any point during treatment with ICIs, including up to 12 months after cessation of treatment.1,2 Guidelines have been developed to support the management of irAEs according to grade: patients experiencing grade 1 irAEs can usually continue ICI therapy; therapy should be temporarily withheld in patients experiencing a grade ≥2 irAE; rechallenge of ICI therapy in patients who have experienced a grade 3 or 4 irAE should be risk-adjusted based on anticipated benefit with therapy vs the potential for toxicity.2,3

Abbreviations

ICI, immune checkpoint inhibitor; irAE, immune-related adverse event.

Question 5/5
Your patient has just been diagnosed with advanced endometrial cancer. Immunohistochemistry shows the tumour is dMMR. Based on the latest data, which of the following first-line treatment approaches would you consider for this patient, assuming all are approved and available in your region?

dMMR, mismatch repair deficient; ICI, immune checkpoint inhibitor; TKI, tyrosine kinase inhibitor.

First-line treatment options available for dMMR endometrial cancer include platinum-based chemotherapy and ICI plus CP.1,2 Data from the RUBY/ENGOT-en6, NRG-GY018/KEYNOTE-868 and AtTEnd/ENGOT-en7 clinical trials show that patients with dMMR advanced or recurrent endometrial cancer receiving an ICI plus CP had a significantly longer PFS vs patients receiving placebo plus CP (p<0.0001; p<0.001 and p=0.0005, respectively).3–5 

Abbreviations

CP, carboplatin and paclitaxel; dMMR, mismatch repair deficient; ICI, immune checkpoint inhibitor; PFS, progression-free survival.
