Key points
- Endometrial cancer (cancer of the womb) starts in the inner lining of the womb and is different from cervical cancer [3]. In high-income countries it is the most common cancer of the female reproductive organs, and the main reason it is becoming more common is obesity [1].
- The most important sign is bleeding after the menopause: about 9 in 10 patients have it. But fewer than 1 in 10 women who bleed after the menopause have cancer [5].
- There is no screening test for women at average risk, and a smear test (Pap test) does not find womb cancer; the best thing to do is to see a doctor promptly about any unusual bleeding [7].
- Because this cancer usually causes symptoms early, most patients are diagnosed early and are cured by surgery to remove the womb [1, 9].
- Today the tumour's "genetic type" (four molecular groups) is also tested; it helps each patient get exactly the treatment she needs: no less, no more [2, 11].
- In advanced or recurrent disease, adding immunotherapy to chemotherapy has delayed the growth of the cancer and, in one large study, also helped patients live longer; the benefit is largest in tumours with a DNA repair defect (dMMR) [26, 28, 29].
What is endometrial (womb) cancer?
The womb (uterus) is a hollow, muscular organ in the pelvis where a baby grows. Its inner lining is called the endometrium, and endometrial cancer starts in the cells of this lining [3]. The lower, narrow end of the womb is the cervix, which opens into the vagina; cervical cancer is a different disease [3]. Cancer that starts in the muscle of the womb wall (uterine sarcoma) is also separate and is treated differently [3].
Endometrial cancer is the most common cancer of the female reproductive organs in high-income countries, and it is becoming more common worldwide; an ageing population and, above all, obesity are the main reasons [1]. In 2020 about 417,000 women worldwide were diagnosed with it and about 97,000 died of it [2].
The good news is that this cancer usually shows itself early through bleeding, so most patients are diagnosed early and are cured by surgery [1, 9].
The pathologist writes the tumour type in the report. Endometrial cancers fall into two broad groups [11]:
Signs and symptoms
The most common and most important symptom is bleeding after the menopause, meaning any bleeding from the womb that happens one year or more after the last period [8]. About 9 in 10 women with womb cancer have this symptom [5]. Even a single episode of bleeding or spotting needs to be checked [8].
Other symptoms [4]:
- Vaginal bleeding or discharge not related to periods (for example, between periods)
- Pain or difficulty passing urine
- Pain during sex
- Pain in the pelvis
Most women who bleed after the menopause do not have cancer: fewer than 1 in 10 do [5]. But because almost all patients have this symptom, checking this bleeding is the best way to find the cancer early [5]. Read more: Symptoms of womb cancer
When should I see a doctor?
If you have any of these, see a doctor (ideally a gynaecologist) promptly:
- Any bleeding or spotting after the menopause, even once and even if it is light [8, 4]
- Unusual bleeding or discharge not related to your periods [4]
- Any vaginal bleeding while you are taking tamoxifen [7]
- Bleeding that continues or comes back after a first check [8]
- Pelvic pain, pain during sex or pain on passing urine that does not go away [4]
Most of these bleeds have a harmless cause [5], but the check is simple and finding cancer early makes treatment simpler.
Risk factors, Lynch syndrome and screening
Most risk factors come down to the endometrium being exposed to the hormone oestrogen for many years [6]. The main ones [6, 10]:
- Obesity and weight gain in adult life; the main reason this cancer is increasing worldwide [1, 6]
- Type 2 diabetes and "metabolic syndrome" (extra fat around the waist, high blood sugar, high blood pressure and high blood fats) [6]
- Oestrogen-only hormone therapy after the menopause; the longer it is used, the higher the risk. Oestrogen combined with a progestogen does not raise the risk of womb cancer, but it does raise the risk of breast cancer [6].
- Tamoxifen (a breast cancer medicine) taken for more than 2 years, especially after the menopause [6]. Do not stop it on your own; just tell your doctor promptly about any bleeding [7].
- Polycystic ovary syndrome [6]
- Lynch syndrome (an inherited condition), and womb cancer in a mother, sister or daughter [6]
- Early first period, late menopause and never having been pregnant [6]
- Abnormal thickening of the womb lining (hyperplasia) [6]
On the other hand, pregnancy and breastfeeding, the combined contraceptive pill, physical activity and weight-loss (bariatric) surgery lower the risk [6].
For women at average risk, no. No regular test has been shown to reduce deaths from womb cancer [7]. The smear test (Pap test) is for cervical cancer and is not used to find womb cancer [7]. Regular ultrasound scans in women without symptoms, even women taking tamoxifen, are not useful; in these women a scan is needed only if they have bleeding [7].
This cancer usually causes bleeding and is found early [7], so the best "screening" is to take any unusual bleeding seriously.
Lynch syndrome is an inherited condition that greatly increases the risk of womb cancer [6] and is also linked to bowel and ovarian cancer [7, 2]. The European guideline recommends for these women [2]:
- from about age 30, a vaginal ultrasound every year and a sample of the womb lining every 1 or 2 years, until the womb is removed;
- once they have finished having children, removal of the womb, tubes and ovaries by keyhole surgery; for most types of the syndrome preferably before age 40, and for one type (PMS2) around the menopause;
- if the ovaries are removed before the menopause, hormone replacement is offered.
Also, the tumour of every woman with womb cancer should be tested for MMR, so that if Lynch syndrome is possible, genetic counselling and testing can be offered to her and her family [2]. Read more: Is cancer hereditary?
Diagnosis and staging
Show detailsHide
How womb cancer is diagnosed
- 1
Ultrasound and a tissue sample at the first visit
For most women who bleed after the menopause, a vaginal ultrasound (to measure the thickness of the womb lining) and a sample of the womb lining are recommended together [8]. Ultrasound alone is enough only for a small group: a single episode of bleeding, a thin and fully seen womb lining, no major risk factors, and quick access to follow-up [8].
- 2
Endometrial biopsy
The doctor passes a thin, flexible tube through the cervix and takes a little of the womb lining to be examined under a microscope [9].
- 3
Hysteroscopy or D&C
Sometimes the doctor looks inside the womb with a thin camera (hysteroscopy) and takes a sample from the suspicious area, or takes a larger sample by dilatation and curettage (D&C) [9].
- 4
Genetic tests on the sample
The same sample is tested for MMR, p53, POLE and the oestrogen receptor [2]. The results help choose treatment and show whether genetic counselling for Lynch syndrome is needed [2].

| Stage | What it means |
|---|---|
| 1 | The cancer is only in the body of the womb [11] |
| 2 | It is still in the womb but has reached the tissue of the cervix, or is seen in many small vessels, or is an aggressive type that has grown into the womb wall [11] |
| 3 | It has spread outside the womb: to an ovary or tube, the outer surface of the womb, the vagina, the tissues beside the womb, the lining of the pelvis or the lymph nodes [11] |
| 4 | It has reached the inner lining of the bladder or bowel, or has spread into the abdomen beyond the pelvis or to distant parts of the body [11] |
In the new staging system, the result of the tumour's genetic tests can also move the stage down or up [11].
For physicians
| Stage | Definition |
|---|---|
| IA1 | Non-aggressive histological type limited to a polyp or confined to the endometrium [11] |
| IA2 | Non-aggressive type with invasion of less than 50% of the myometrium and no or focal LVSI [11] |
| IA3 | Low-grade endometrioid carcinoma limited to the uterus with simultaneous low-grade endometrioid ovarian involvement (myoinvasion less than 50%, no substantial LVSI, no other metastases, unilateral ovarian tumour limited to the ovary without capsule rupture) [11] |
| IB | Non-aggressive type with invasion of 50% or more of the myometrium and no or focal LVSI [11] |
| IC | Aggressive type without any myometrial invasion (limited to a polyp or the endometrium) [11] |
| IIA | Invasion of the cervical stroma by a non-aggressive type [11] |
| IIB | Substantial LVSI in a non-aggressive type [11] |
| IIC | Aggressive type with any myometrial invasion [11] |
| IIIA1 | Spread to the ovary or fallopian tube (except cases meeting stage IA3 criteria) [11, 2] |
| IIIA2 | Involvement of the uterine subserosa or spread through the uterine serosa [11, 2] |
| IIIB1 | Metastasis or direct spread to the vagina and/or parametria [11, 2] |
| IIIB2 | Metastasis to the pelvic peritoneum [11, 2] |
| IIIC1 | Pelvic lymph node metastasis: IIIC1i micrometastasis, IIIC1ii macrometastasis [11, 2] |
| IIIC2 | Para-aortic lymph node metastasis up to the renal vessels: IIIC2i micrometastasis, IIIC2ii macrometastasis [11, 2] |
| IVA | Invasion of the bladder and/or intestinal mucosa [11, 2] |
| IVB | Peritoneal metastasis beyond the pelvis [11, 2] |
| IVC | Distant metastasis [11, 2] |
| IAm POLEmut | Stage I and II disease with a pathogenic POLE mutation [2, 11] |
| IICm p53abn | Stage I and II disease with abnormal p53 and myometrial invasion [2, 11] |
Aggressive types: grade 3 endometrioid, serous, clear cell, undifferentiated, mixed, mesonephric-like, gastrointestinal-type mucinous carcinoma and carcinosarcoma; non-aggressive types: grade 1 and 2 endometrioid [11]. Micrometastasis: deposits larger than 0.2 mm and up to 2 mm, or more than 200 cells; the significance of isolated tumour cells (0.2 mm or less) is unclear [IV, C] [2]. When the molecular classification is known, the stage is reported with "m" and the molecular subtype [11].
Molecular classification: four genetic groups of tumour
Today, as well as the stage, the tumour's "genetic type" is also tested. Endometrial cancers fall into four groups [12, 2]:
- POLE mutation: even if it looks aggressive under the microscope, the outlook is excellent; in one large study almost none of these patients had their cancer come back [13]. Often no further treatment is needed after surgery [2].
- DNA repair defect (dMMR): responds very well to immunotherapy [26, 28] and is sometimes a sign of Lynch syndrome [2].
- Abnormal p53: the most aggressive group; stronger treatment (chemotherapy with radiotherapy) helps these patients most [13].
- No specific molecular profile: the risk depends mostly on the tumour grade and the oestrogen receptor [2].
Ask your doctor what these test results show in your report; they may make your treatment lighter or more complete [2].
For physicians
| Group | How it is identified | Prognosis in PORTEC-3 | Treatment implications (ESGO/ESTRO/ESP 2025) |
|---|---|---|---|
| POLEmut | Sequencing of all 11 pathogenic POLE exonuclease domain variants [IV, B] [2] | 12% of patients; 5-year recurrence-free survival 98% (100% with chemoradiotherapy vs 97% with radiotherapy) [13] | Stages I and II → IAm POLEmut and low risk, no adjuvant therapy; in IIIm and IVAm data are insufficient and de-escalation after multidisciplinary discussion can be considered [IV, B] [2] |
| MMRd | IHC for MMR proteins (two- and four-antibody approaches are equivalent); MLH1 promoter methylation testing when MLH1 is lost; MSI by PCR if results are equivocal [IV, B] [2] | 33%; 5-year recurrence-free survival 72%; no benefit from adding chemotherapy (68% vs 76%) [13] | Advanced or recurrent disease: immune checkpoint inhibitor + carboplatin–paclitaxel, then maintenance [I, A]; after surgery in IIIm and IVAm: chemotherapy + immune checkpoint inhibitor should be considered [II, B] [2] |
| p53abn | p53 IHC (overexpression, null or cytoplasmic pattern); TP53 sequencing if the pattern is equivocal or heterogeneous [IV, B] [2] | 23%; 5-year recurrence-free survival 48%; 59% with chemoradiotherapy vs 36% with radiotherapy (P=0.019) [13] | Stages I and II with myometrial invasion → IICm p53abn and high risk: external beam radiotherapy with concurrent and adjuvant chemotherapy [I, A] [2] |
| NSMP | None of the three features above; oestrogen receptor by IHC (positive: 10% or more) [IV, A] [2] | 32%; 5-year recurrence-free survival 74% (80% vs 68%; P=0.243) [13] | Low-grade ER-positive NSMP versus high-grade or ER-negative NSMP determines the risk group [2] |
Multiple classifiers: POLEmut with MMRd or p53abn → POLEmut; MMRd with p53abn → MMRd [IV, B]. Testing on the biopsy or curettage specimen is preferred and is repeated on the hysterectomy specimen only in specific situations [IV, B]. In advanced or recurrent p53abn cancer and in all serous carcinomas and carcinosarcomas, HER2 overexpression can be assessed by IHC [IV, C] [2].
Treatment by stage
The main treatments
Surgery
The main treatment: removal of the whole womb and cervix together with both tubes and ovaries, and checking of the sentinel lymph nodes [2]. Most patients have keyhole surgery (laparoscopic or robotic), which has fewer complications and a shorter hospital stay and works as well as open surgery [2, 14, 16].
Radiotherapy
Chemotherapy
For high-risk or spread disease; usually two drugs, carboplatin and paclitaxel, every 3 weeks; in advanced disease usually 6 cycles [10, 2].
Immunotherapy
Treatment at each stage, in plain words
- 1
Stage 1, low risk
Surgery alone; usually no other treatment is needed [2].
- 2
Stage 1 or 2, intermediate risk
- 3
- 4
Stage 4 or cancer that has come back
Chemotherapy with immunotherapy [2, 26, 28]; for less aggressive, slow-growing tumours with hormone receptors, hormone tablets [2]. If the cancer comes back after chemotherapy, immunotherapy alone or with the tablet lenvatinib [2, 32]. Sometimes surgery or radiotherapy is also used for limited disease [2].
- 5
If surgery is not possible
External radiotherapy and radiotherapy inside the womb instead of surgery [2].
For physicians
Adjuvant treatment by risk group (ESGO/ESTRO/ESP 2025)
- 1
- 2
Intermediate risk
IBm MMRd or low-grade ER-positive NSMP; IIAm low-grade ER-positive NSMP; IICm MMRd with myometrial invasion, without cervical stromal invasion and without substantial LVSI. Adjuvant vaginal brachytherapy should be considered [I, A]; no adjuvant therapy is also an option [III, C], especially under 60 years or for low-grade tumours [II, A] [2].
- 3
High–intermediate risk
IIAm MMRd; IIBm MMRd or low-grade ER-positive NSMP; IICm MMRd with cervical invasion or substantial LVSI. External beam radiotherapy for optimal pelvic control [II, A]; vaginal brachytherapy is an alternative, especially after nodal staging with pN0 [II, B]; no adjuvant therapy can be considered in pN0 without substantial LVSI and low grade [IV, B] [2].
- 4
High risk
IA2m, IA3m, IBm and IIm in high-grade or ER-negative NSMP or p53abn; IIIm and IVAm in MMRd, NSMP and p53abn. External beam radiotherapy with concurrent and adjuvant chemotherapy [I, A] or sequential chemotherapy and radiotherapy [I, B]; chemotherapy with or without brachytherapy is an alternative [I, B]; in IIIm and IVAm MMRd, chemotherapy plus an immune checkpoint inhibitor (with or without external beam radiotherapy) should be considered [II, B] [2].
- 5
Uncertain risk
IA1m and ICm in high-grade or ER-negative NSMP or p53abn: scarce data; adjuvant therapy is generally not recommended [IV, C]. IIIm and IVAm POLEmut: after multidisciplinary discussion, de-escalation from high-risk treatment can be considered [IV, B] [2].
- 6
Medically unfit for surgery
Definitive radiotherapy: EBRT plus image-guided intrauterine brachytherapy for high-grade tumours or deep myometrial invasion; for low-grade tumours without deep invasion, brachytherapy alone is an alternative [II, B]. Vaginal hysterectomy with bilateral salpingo-oophorectomy if feasible [IV, C] [2].
Keeping the womb for pregnancy in young women
In young women who still want to become pregnant, the womb can be kept for a while in one specific group: grade 1 endometrioid cancer that is only in the womb lining and has not grown into the womb wall [33]. This decision should be made at a specialist centre, together with a gynaecological cancer specialist and a fertility specialist [33].
The best approach is removal of the lesion by hysteroscopy followed by progestogen tablets or a hormone-releasing coil (IUD) [33]. Treatment usually lasts 6 to 12 months and is checked with regular biopsies [33]. Losing weight improves the chances of the treatment working and of pregnancy [33]. Once you have finished having children, removal of the womb is recommended [33]. Read more: Sex and fertility
For physicians
ESGO/ESHRE/ESGE guideline: fertility-sparing treatment for grade 1 endometrioid carcinoma, stage IA without myometrial invasion and without risk factors [V, A]; for grade 2, case by case [IV, C]. Hysteroscopic-guided biopsy is preferred over blind biopsy [III, A]; myometrial invasion should be assessed by MRI or transvaginal ultrasound by a specialised radiologist or sonographer [III, A], CT should not be used for this [III, A], and MRI or CT for nodes and metastases [II, B]. Hysteroscopic resection followed by oral progestogens and/or an LNG-IUD gives the highest complete response and live birth rates [II, B]; GnRH analogues are not first line [II, B] [33].
Complete response should be reached within 6 to 12 months [III, B], with a maximum of 15 months [IV, C]; no response at all at 6 months → multidisciplinary counselling [IV, B]. Success: two consecutive biopsies showing complete response at least 3 months apart [IV, C]; follow-up with examination and ultrasound every 3 months and histological assessment by hysteroscopy every 3 to 6 months [IV, B]. Conservative treatment is inappropriate for p53abn tumours [IV, D]; MMR IHC is mandatory to identify Lynch syndrome [III, A], and in Lynch syndrome the decision is case by case [II, A]. Definitive surgery for non-response, inability to conceive, recurrence or progression [II, A], and completion surgery after childbearing [II, A]; removal of the ovaries case by case [III, B] [33]. Doses are given in the section "Treatment regimens and doses (for doctors)".
If the cancer is advanced or comes back
If the cancer has spread beyond the pelvis or has come back after treatment, chemotherapy and immunotherapy are usually given together, and then immunotherapy continues on its own [2]. In large studies this combination delayed the growth of the cancer [26, 28], and in one of them it also helped patients live longer [29]. The benefit was largest in dMMR tumours: one year after starting treatment, about twice as many patients were free of cancer growth [26].
For less aggressive, slow-growing tumours with hormone receptors, hormone tablets (progestogens) can be the first treatment [2]. If the cancer comes back after chemotherapy, immunotherapy alone (in dMMR tumours) or with the tablet lenvatinib are the next options [2, 32]. If only one or a few limited spots are affected, surgery or radiotherapy may also be possible [2]. Read about the side effects of immunotherapy: Immunotherapy side effects

Frequently asked questions
Is womb cancer different from cervical cancer?
Yes. Womb (endometrial) cancer starts in the inner lining of the body of the womb; the cervix is the lower, narrow part of the womb that opens into the vagina, and cancer there is a different disease [3]. The tests are different too: the smear test (Pap test) is for the cervix and does not find endometrial cancer [7].
Does bleeding after the menopause mean I have cancer?
Do I need a yearly ultrasound to prevent it?
For women at average risk without symptoms, no; no study has shown that regular ultrasound scans reduce deaths from this cancer [7]. The exception is women with Lynch syndrome, who have a special check-up plan [2].
Does keyhole (laparoscopic) surgery work as well as open surgery?
Yes. In two large studies, results with keyhole surgery were about the same as with open surgery [15, 16], with fewer complications and a shorter hospital stay [14]. The European guideline names keyhole surgery as the preferred approach, even for high-risk disease [2]. This is different from cervical cancer, where keyhole surgery gave worse results [17].
Are all the lymph nodes removed?
Will I go through the menopause after removal of the womb?
If you have not yet reached the menopause and your ovaries are removed too, yes. That is why, in women under 45 with low-risk disease, the ovaries are sometimes kept, as long as there is no inherited risk such as Lynch syndrome or a BRCA mutation [2]. Talk to your doctor about menopausal symptoms and how to manage them [2].
What is internal radiotherapy (brachytherapy)?
A small cylinder is placed in the vagina and the radiation reaches only the upper part of the vagina; in the main study this was 3 sessions one week apart [20]. It prevented the cancer coming back in the vagina as well as external radiotherapy to the pelvis did, with far fewer bowel side effects [19].
Does immunotherapy help every patient?
Not every patient. In advanced or recurrent disease it helps when given with chemotherapy, and much more so in dMMR tumours [26, 28]. But after complete surgery for high-risk disease, adding it to chemotherapy did not reduce the chance of the cancer coming back in patients overall [24]. Your doctor decides based on the stage and the MMR test.
Evidence and recent advances (for doctors)
Show detailsHide
Surgery
Standard surgery for stage I and II disease is total hysterectomy with bilateral salpingo-oophorectomy and lymph node staging [II, A for stage I; IV, B for stage II]; infracolic omentectomy only for serous carcinoma, carcinosarcoma and undifferentiated carcinoma [IV, B]. Minimally invasive surgery is the preferred approach, including for high-risk disease [I, A]; any intraperitoneal tumour spillage, including rupture or morcellation (even in a bag), should be avoided [III, A] [2]. In LAP2 (2616 patients with clinical stage I to IIA), laparoscopy had fewer moderate-to-severe postoperative adverse events (14% vs 21%) and fewer hospital stays longer than 2 days (52% vs 94%); 74.2% of laparoscopies were completed without conversion [14]. The recurrence HR of 1.14 did not meet the prespecified non-inferiority criterion, but 3-year recurrence was 11.4% vs 10.2% and 5-year overall survival was 89.8% in both arms [15]. In LACE (760 patients with stage I endometrioid cancer), 4.5-year disease-free survival was 81.6% with laparoscopy and 81.3% with laparotomy (equivalence) [16]. This must not be confused with cervical cancer: in LACC, minimally invasive radical hysterectomy had lower 4.5-year disease-free survival (86.0% vs 96.5%) [17].
Sentinel lymph node biopsy is recommended for all patients with presumed uterus-confined disease [II, A]; ICG with cervical injection is the preferred technique; if no sentinel node is found on one side, side-specific systematic lymphadenectomy in high–intermediate and high risk [II, A]; all sentinel nodes should undergo ultrastaging [II, A] [2]. In FIRES (340 patients), at least one sentinel node was mapped in 86%; sensitivity was 97.2% and negative predictive value 99.6% [18]. Ovarian preservation can be considered in women under 45 with FIGO 2023 IA1 or IA2 and low risk by molecular classification, with bilateral salpingectomy, but not in carriers of BRCA mutations or Lynch syndrome [IV, B] [2]. In stage III and IV disease, cytoreduction (including removal of suspicious nodes) should be considered when complete resection is feasible with acceptable morbidity; systematic lymphadenectomy is not recommended [IV, B] [2].
Adjuvant treatment: brachytherapy or external beam radiotherapy
In PORTEC-2 (427 patients with stage I or IIA high–intermediate-risk disease), 5-year vaginal recurrence was 1.8% with vaginal brachytherapy and 1.6% with external beam radiotherapy (HR 0.78), with no difference in overall survival (84.8% vs 79.6%) or disease-free survival; acute grade 1–2 gastrointestinal toxicity at the end of radiotherapy was 12.6% vs 53.8% [19]. At 10 years, vaginal recurrence was 3.4% vs 2.4% and overall survival 69.5% vs 67.6%; pelvic recurrence was more frequent with brachytherapy (6.3% vs 0.9%), mostly together with distant metastases; substantial LVSI, p53-mutant expression and L1CAM expression were risk factors for pelvic and distant recurrence, and external beam radiotherapy reduced pelvic recurrence in these cases [20].
Adjuvant treatment in high-risk disease
In PORTEC-3 (660 high-risk patients), chemoradiotherapy (two cycles of concurrent cisplatin followed by 4 cycles of carboplatin–paclitaxel) improved 5-year failure-free survival in the first final analysis (75.5% vs 68.6%; HR 0.71) but not overall survival significantly (HR 0.76); grade 3 or worse adverse events during treatment were 60% vs 12% [21]. In the updated analysis at a median follow-up of 72.6 months, 5-year overall survival was 81.4% vs 76.1% (HR 0.70; p=0.034) and failure-free survival 76.5% vs 69.1% (HR 0.70); the largest absolute benefit was in stage III (overall survival 78.5% vs 68.5%; HR 0.63) and serous cancers (71.4% vs 52.8%; HR 0.48); grade 2 or worse sensory neuropathy at 5 years was 6% vs 0% [22]. In the molecular analysis, the benefit of chemotherapy was significant only in p53abn (5-year recurrence-free survival 59% vs 36%), and POLEmut tumours did very well in both arms [13].
In GOG-258 (736 patients with stage III or IVA and residual disease of at most 2 cm), chemoradiotherapy did not improve relapse-free survival compared with 6 cycles of carboplatin–paclitaxel (59% vs 58% at 60 months; HR 0.90); vaginal recurrence (2% vs 7%) and pelvic and para-aortic nodal recurrence (11% vs 20%) were lower, but distant recurrence was higher (27% vs 21%) [23]. So in stage III both strategies are accepted: ESGO lists external beam radiotherapy with concurrent and adjuvant chemotherapy [I, A] and chemotherapy with or without brachytherapy as an alternative [I, B] [2].
In KEYNOTE-B21 (1095 high-risk patients with no residual disease after surgery), adding pembrolizumab to adjuvant chemotherapy (with or without radiotherapy) did not improve disease-free survival (HR 1.02; 2-year disease-free survival 75% vs 76%), and grade 3 or worse adverse events were more frequent (71% vs 63%) [24]; the FDA label also records a "lack of effectiveness for adjuvant treatment" [37]. In the dMMR subgroup (281 patients) the HR was 0.31, and in pMMR 1.20 (prespecified subgroup analysis) [24]. ESGO considers adding an immune checkpoint inhibitor to adjuvant chemotherapy only in IIIm and IVAm MMRd disease [II, B] [2].
Advanced or recurrent disease: first line
Carboplatin–paclitaxel has been the global standard since GOG-0209: in 1381 patients it was non-inferior to TAP (paclitaxel, doxorubicin and cisplatin) (median overall survival 37 vs 41 months; HR 1.002) and less toxic [25]. In four phase 3 trials, adding an immune checkpoint inhibitor to this regimen, followed by maintenance, improved progression-free survival, with the largest benefit in dMMR (table below) [26, 28, 30, 31].
In NRG-GY018, overall survival data are still immature, but the HRs favoured pembrolizumab (pMMR 0.79; dMMR 0.55) [27]. In RUBY, overall survival in the overall population was significantly better at the second interim analysis (HR 0.69); in pMMR/MSS the HR was 0.79 [29]. In DUO-E, adding olaparib to maintenance durvalumab gave more benefit in pMMR (HR 0.57 vs 0.77) [30]. In AtTEnd, the benefit of atezolizumab in the overall population was small, and interim overall survival did not cross the stopping boundary [31].
ESGO 2025: in MMRd, an immune checkpoint inhibitor (such as pembrolizumab, dostarlimab or durvalumab) with carboplatin–paclitaxel, followed by maintenance [I, A]; in non-MMRd with rapidly growing or symptomatic disease, carboplatin–paclitaxel [I, A], and adding an immune checkpoint inhibitor (such as pembrolizumab or dostarlimab), or an immune checkpoint inhibitor followed by maintenance with durvalumab and olaparib, can be considered [I, B]; the standard chemotherapy is 6 cycles of carboplatin–paclitaxel [I, A]. If chemotherapy is contraindicated and a non-MMRd patient has had previous adjuvant or neoadjuvant chemotherapy, pembrolizumab + lenvatinib [III, C]; in HER2 3+ disease when immune checkpoint inhibitors are contraindicated, carboplatin–paclitaxel + trastuzumab [II, B]. In low-grade ER-positive tumours that are low volume, asymptomatic or slowly growing, endocrine therapy is preferred: progestogens (medroxyprogesterone or megestrol) [III, A], with aromatase inhibitors and tamoxifen as alternatives [IV, C] [2].
| Trial | Intervention | Progression-free survival in dMMR | Progression-free survival in pMMR or overall | Overall survival |
|---|---|---|---|---|
| NRG-GY018 [26, 27] | Pembrolizumab for 6 cycles with chemotherapy, then maintenance every 6 weeks for up to 14 cycles | 12-month 74% vs 38%; HR 0.30 | pMMR: median 13.1 vs 8.7 months; HR 0.54 | Immature; pMMR HR 0.79, dMMR HR 0.55 |

There is no head-to-head comparison between these trials; eligibility, length of maintenance and timing of analyses differ. NRG-GY018 excluded carcinosarcoma, whereas AtTEnd included it. The MMR subgroup analyses in DUO-E were exploratory.
Second line and beyond
In KEYNOTE-775 (827 patients after platinum-based chemotherapy), lenvatinib + pembrolizumab improved overall survival compared with doxorubicin or weekly paclitaxel in pMMR (median 17.4 vs 12.0 months; HR 0.68) and in all patients (18.3 vs 11.4 months; HR 0.62); grade 3 or worse adverse events were 88.9% vs 72.7% [32]. Single-agent pembrolizumab in MSI-H or dMMR disease after prior systemic therapy (KEYNOTE-158, 90 patients) gave an objective response rate of 46% with 12% complete responses [37]; single-agent dostarlimab is also FDA-approved for dMMR disease after a platinum-containing regimen [38].
ESGO 2025: in immunotherapy-naive patients, MMRd → immune checkpoint inhibitor monotherapy (pembrolizumab or dostarlimab) [III, A], with pembrolizumab + lenvatinib as an option [I, B]; non-MMRd → pembrolizumab + lenvatinib [I, A]. If this is not suitable, or the patient received immunotherapy in the first line: a platinum combination, doxorubicin, weekly paclitaxel or endocrine therapy [IV, B]; for HER2-overexpressing tumours, HER2-targeting strategies [II, B and III, B]. If feasible, MMR testing should be repeated on a sample of the recurrence [IV, B]. For locoregional recurrence without previous radiotherapy, external beam radiotherapy with or without brachytherapy and chemotherapy [IV, A], and for oligometastatic disease (1 to 5 lesions in up to 3 regions) local treatment [IV, B] [2].
Hormone therapy: in a GOG trial, oral medroxyprogesterone 200 mg daily gave a 25% response rate (17% complete) and 1000 mg daily was not better (15%); responses were more frequent in well-differentiated, progesterone receptor-positive tumours and only 8% to 9% in poorly differentiated or progesterone receptor-low tumours [34]. Everolimus + letrozole gave an objective response rate of 32% (9 complete responses among 35 patients) in a phase 2 study, and serous histology was the strongest predictor of no response [35]. In the randomised phase 2 GOG-3007 trial, the response rate was 22% with everolimus + letrozole and 25% with medroxyprogesterone alternating with tamoxifen; in chemotherapy-naive patients, median progression-free survival with everolimus + letrozole was 28 months, and grade 3–4 thromboembolic events occurred only with medroxyprogesterone/tamoxifen (11%) [36].
Treatment regimens and doses (for doctors)
Show detailsHide
Treatment regimens and doses: index19 regimens
Carboplatin: dose by the Calvert formula: total dose (mg) = target AUC × (GFR + 25); a cycle should not be repeated until neutrophils are at least 2000 and platelets at least 100,000 [42].
Paclitaxel: premedication for all patients: dexamethasone 20 mg orally about 12 and 6 hours before the infusion, diphenhydramine 50 mg IV and cimetidine 300 mg or ranitidine 50 mg IV 30 to 60 minutes before the infusion. Do not give if baseline neutrophils are below 1500; after severe neutropenia (below 500 for a week or longer) or severe peripheral neuropathy, reduce the dose of later cycles by 20% [43].
Immune checkpoint inhibitors (pembrolizumab, dostarlimab, durvalumab): determine MMR status with a validated test before starting [2]. No dose reductions are recommended; withhold for severe (grade 3) immune-mediated reactions, and discontinue permanently for grade 4 reactions, recurrent grade 3 reactions needing systemic immunosuppression, or inability to taper corticosteroids to 10 mg prednisone or less per day within 12 weeks [37, 38, 39]; grade 2 or higher myocarditis on pembrolizumab → permanent discontinuation [37]. On shared days, give pembrolizumab and dostarlimab before carboplatin and paclitaxel [37, 38].
Olaparib: blood counts at baseline and then monthly (MDS/AML in about 1.2% of patients across cancers); interrupt if pneumonitis is suspected and discontinue if confirmed; monitor for venous thromboembolism; avoid strong or moderate CYP3A inhibitors (if unavoidable, 100 or 150 mg twice daily); with creatinine clearance 31 to 50 mL/min, 200 mg twice daily [40].
Lenvatinib: control blood pressure before starting and monitor during treatment; withhold for grade 3 hypertension that persists despite optimal treatment and resume at a lower dose once controlled; discontinue permanently for grade 4 [41].
Progestogens: thrombophlebitis and pulmonary embolism (sometimes fatal) have been reported with megestrol, which should be used with caution in patients with a history of thromboembolism; it may worsen diabetes [44].
