Endometrial Cancer Disease Understanding and Treatment Algorithm

Endometrial Cancer Overview

Endometrial cancer is cancer of the endometrium, the lining of the uterus. It is the most common type of cancer that affects the female reproductive organs. A pre-invasive intraepithelial lesion progresses to invasive cancer involving the endometrial stroma and then penetrates even more deeply into the myometrium. The lymphatic capillaries become engaged, carrying the malignancy to regional lymph nodes, where metastases may occur through vascular channels. Tumorous involvement of the uterine cervix and stroma most likely occurs through lymphatic channels, particularly by dedifferentiated carcinomas. However, surface spread can occur from endometrial cancers in the lower uterine segment.

Endometrial Cancer Classification

Type I (low-grade endometrial endometrioid carcinomas): They are with less than 50% myometrium invasion and have a favourable prognosis, approaching 100% 5-year survival rates. They are usually not very aggressive, and they do not spread to other tissues quickly. They are thought to be caused by too much estrogen. They sometimes develop from atypical hyperplasia, an abnormal overgrowth of cells in the endometrium.

Type II (high-grade non-endometrioid): They are serous, undifferentiated, and clear cell carcinomas. They are associated with a significantly poorer 5-year survival rate. They are more likely to grow and spread outside the uterus.

Endometrial Cancer Diagnosis

Early detection means a better prognosis. A full drug history and a gynecology history have to be obtained via pelvic examinations. Two investigations are mandatory in women with suspected endometrial cancer: a transvaginal ultrasound scan and an endometrial biopsy. In the endometrial biopsy, a thin, flexible tube is inserted through the cervix and into the uterus. Using suction, a small amount of tissue is removed through the tube. If an endometrial biopsy is unable to be performed, Dilation and Curettage (D&C) may be done in the operating room. The cervix is dilated (enlarged) with a series of increasingly larger metal rods. A tool called a curette is then used to take cells from the uterus lining. A thin, telescope-like device with a light (hysteroscope) is put into the uterus through the vagina. The doctor then looks at the uterus and the openings to the fallopian tubes. Small pieces of tissue can be removed. Hysteroscopy may be done with a D&C. If endometrial cancer is diagnosed, imaging will likely need to be performed to find out more about what the disease looks like and to see if it may have spread outside of the uterus. Ultrasound, MRI, CT, etc., can be performed for that purpose. Various blood tests like Complete Metabolic Panel (CMP), Complete Blood Count (CBC), etc., can be done to have a better understanding of the indication.

Endometrial Cancer Treatment

Surgery is the first treatment for almost all women with endometrial cancer. The operation includes removing the uterus, fallopian tubes, and ovaries. After surgery, chemotherapy with or without radiation therapy is given to help keep the cancer from coming back. The chemotherapy usually includes the drugs carboplatin and paclitaxel, but other drugs can also be used. Progestin therapy can also be given if the woman wants to have a pregnancy. It can cause the cancer to shrink or even go away for some time. One treatment option is to have surgery first, followed by radiation therapy. The surgery includes a radical hysterectomy, removal of both fallopian tubes and ovaries, and pelvic and para-aortic lymph node dissection or sampling. Combinations of chemotherapy drugs may help some women for a time.

Endometrial Cancer Epidemiology

As the market is derived using a patient-based model, the endometrial cancer epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented by total incident cases of endometrial cancer, subtype-specific incident cases of endometrial cancer, mutation-specific incident cases of endometrial cancer, age-specific incident cases of endometrial cancer, stage-specific incident cases of endometrial cancer, and line-wise treated cases of endometrial cancer in the 7MM covering the United States, EU4 countries (Germany, France, Italy, and Spain) and the United Kingdom, and Japan from 2020 to 2034.

• In the US, approximately, 67,880 women were diagnosed with endometrial cancer in 2024.
• In 2022, the endometrial cancer cases were 66,055 in the US, 11,767 in Germany, 9,760 in France, 10,202 in Spain, 10,440 in the UK, and 18,338 in Japan.
• In 2020, there were 130,051 estimated incident cases of endometrial cancer in Europe, and there were 29,963 deaths.
• In Spain, endometrial cancer is the fourth most common cancer in women (behind breast, lung, and colon and rectal cancer). It has an incidence per 100,000 women of 13-14 cases per year, with a mortality of 3-4 cases.
• In Spain, the average age of diagnosis is 63 years. Although most patients are diagnosed after 55 years of age, up to 25% of cases are identified before that age, and 5-6% between 35 and 44 years of age.
• In females in the UK, uterine cancer is the fourth most common cancer, with around 9,800 new cases every year.
• In Europe, approximately 69-75% of patients with endometrial cancer have pMMR/MSS tumours.
• The incidence of endometrial cancer throughout Asia is heterogeneous, with 10.2 per 100,000 in Japan.

KEYTRUDA is in combination with lenvatinib for the treatment of adult patients with advanced endometrial carcinoma that is pMMR as determined by an FDA-approved test or not MSI-H, who have disease progression following prior systemic therapy in any setting and are not candidates for curative surgery or radiation. It is developed as a single agent for the treatment of adult patients with advanced endometrial carcinoma that is MSI-H or dMMR, as determined by an FDA-approved test, who have disease progression following prior systemic therapy in any setting and are not candidates for curative surgery or radiation.

• In July 2021, the FDA approved KEYTRUDA in combination with lenvatinib for patients with advanced endometrial carcinoma who have disease progression following prior systemic therapy in any setting and are not candidates for curative surgery or radiation.
• In March 2022, the FDA approved KEYTRUDA as a single agent for patients with advanced endometrial carcinoma that is MSI-H or dMMR, who have disease progression following prior systemic therapy in any setting and who are not candidates for curative surgery or radiation.
• In June 2024, the FDA approved it for adult patients with primary advanced or recurrent endometrial carcinoma.

IMFINZI (durvalumab): AstraZeneca

IMFINZI is a human monoclonal antibody that binds to the PD-L1 protein and blocks the interaction of PD-L1 with the PD-1 and CD80 proteins, countering the tumor’s immune-evading tactics and releasing the inhibition of immune responses. As a single agent, it is developed in combination with carboplatin and paclitaxel for the treatment of adult patients with primary advanced or recurrent endometrial cancer that is dMMR.

In June 2024, the FDA approved IMFINZI in combination with carboplatin plus paclitaxel for adult patients with primary advanced or recurrent endometrial cancer that is dMMR. Efficacy was evaluated in DUO-E Phase III, a randomized, multicenter, double-blind, placebo-controlled trial in patients.

Emerging Drugs

Sacituzumab tirumotecan (MK-2870): Merck

It is a recombinant humanized IgG1 anti-TROP2 monoclonal antibody conjugated to a topoisomerase I inhibitor. It is a third-generation Antibody-drug Conjugate (ADC) that acts by targeting cells expressing (trophoblast antigen) TROP2. It is administered through an intravenous route in the form of powder. The drug candidate is being developed based on the ADC conjugation technology. It is under development for the treatment of endometrial carcinoma and other indications. It is currently being evaluated in the Phase III trial.

XPOVIO (selinexor): Karyopharm Therapeutics

It is a first-in-class, oral Selective Inhibitor of Nuclear Export (SINE) compound. It functions by binding with and inhibiting the nuclear export protein, XPO1, leading to the accumulation of tumor suppressor proteins in the cell nucleus. This reinitiates and amplifies their tumor suppressor function and is believed to lead to the selective induction of apoptosis in cancer cells, while largely sparing normal cells. It is currently being evaluated in the Phase III trial (the SIENDO study) as a maintenance therapy versus placebo in patients with endometrial cancer after first- or second-line chemotherapy. Another Phase III trial (XPORT-EC-042) is evaluating selinexor as a maintenance treatment for patients with TP53 wild-type advanced or recurrent endometrial cancer, with the company expecting to release the data by mid-2026.

Drug Class Insights

The market of endometrial carcinoma is mainly dominated by PD-1 inhibitors like KEYTRUDA, IMFINZI, and JEMPERLI. Although the first approval as a combination of RTK inhibitor + PD-1 inhibitor, i.e., LENVIMA + KEYTRUDA, in 2019. But since then, various PD-1 inhibitors have come in front to treat endometrial cancer.

The emerging landscape does hold a diversity of drug classes, being investigated to treat different patient segments of endometrial cancer. Some of the very strong assets in the pipeline are ENHERTU and XPOVIO. This is due to their previous approvals and strong uptake. Their approvals will change the market scenario. MK-2870, an anti-TROP2 ADC, is another therapy with a very promising class. Giredestrant, an emerging SERD, a newly introduced drug class, is expected to transform the treatment of endometrial cancer. The market of endometrial cancer holds a void, creating an opportunity for many classes to get approvals and treat various segments of endometrial cancer.

Endometrial Cancer Market Outlook

The gold standard treatment for endometrial cancer is hysterectomy. However, in the last few years, several drugs such as KEYTRUDA, first approved in 2021, and others have received regulatory approval for endometrial cancer in the US. These drugs can be administered intravenously or orally. The Cancer Genome Atlas Project (TCGA) identified specific types of endometrial cancer tumors based on genomic characterization that have been shown to be reliable prognostic biomarkers for this disease. These endometrial cancer types are either dMMR or MSI-H. The recent approval of treatments specific to tumor status has changed the treatment landscape for patients with recurrent or advanced endometrial cancer.

These recent successful developments include PD-1 inhibitors in the form of drugs such as JEMPERLI and IMFINZI. LENVIMA + KEYTRUDA recently got approval from the FDA in 2022 for patients with advanced endometrial cancer and not dMMR or MSI-H. Other standard therapies include carboplatin taxol, megestrol acetate, medroxyprogesterone acetate, etc. However, more effective therapeutic approaches against endometrial cancer are necessary to improve clinical outcomes further.

Key players like Merck, Karyopharm Therapeutics, Faeth Therapeutics, GSK, and others are evaluating their lead candidates in different stages of clinical development.

Key Findings

• As per the corporate presentation of Karyopharm Therapeutics 2025, the company is anticipating the Phase III trial (XPORT-EC-042) data, evaluating selinexor as a maintenance treatment for patients with TP53 wild-type advanced or recurrent endometrial cancer, by mid-2026.
• In June 2025, Daiichi Sankyo announced that the first patient dosing for the Phase III DESTINY- Endometrial01 study of ENHERTU in combination with rilvegostomig or pembrolizumab versus platinum-based chemotherapy (carboplatin and paclitaxel) in combination with pembrolizumab as a first-line therapy in patients with HER2 expressing (IHC 3+/ 2+), pMMR primary advanced or recurrent endometrial cancer.

Endometrial Cancer Drugs Uptake

Both JEMPERLI and KEYTRUDA are currently allowed as single agents in a subtype of endometrial cancer with the dMMR biomarker. KEYTRUDA also carries an additional indication for use alongside Eisai-partnered LENVIMA in previously treated endometrial cancer. JEMPERLI acts as a strong contender to KEYTRUDA; however, till now, KEYTRUDA has managed to maintain its stronger uptake in the field.

This section focuses on the uptake rate of potential drugs expected to be launched in the market during 2025-2034, which depends on the competitive landscape, safety, efficacy data, and order of entry. It is important to understand that the key players evaluating their novel therapies in the pivotal and confirmatory trials should remain vigilant when selecting appropriate comparators to stand the greatest chance of a positive opinion from regulatory bodies, leading to approval, smooth launch, and rapid uptake.
