Stage 3 Endometrial Cancer Treatment

The short answer: Stage 3 endometrial cancer (womb cancer, bachedani ka cancer, बच्चेदानी का कैंसर) means the cancer has spread beyond the womb to nearby areas: the outer surface of the womb, the ovaries or fallopian tubes, the vagina or the tissues beside the womb, or lymph nodes (glands) in the pelvis or abdomen. It has not spread into the bladder or bowel or to distant organs. Many women are still treated with the aim of cure. Treatment usually combines surgery with chemotherapy, often with radiotherapy (sikai), and for some women immunotherapy; the order and mix depend on where the cancer is and on tests on the tumour. Dr. Nishtha Tripathi Patel treats stage 3 endometrial cancer at Sterling Hospitals, KD Hospital and Welcare Speciality Hospital in Ahmedabad.

What does this stage mean?

In the widely used FIGO staging system, stage 3 is divided into three groups:

Stage 3A: the cancer has reached the outer surface of the womb (serosa), or the fallopian tubes or ovaries (adnexa).
Stage 3B: the cancer has spread to the vagina or to the tissues beside the womb (parametrium).
Stage 3C: the cancer has spread to lymph nodes in the pelvis (3C1) or along the main blood vessels in the abdomen (para-aortic nodes, 3C2).

The stage is confirmed after surgery and scans. The report also describes the type and grade of cancer and, increasingly, molecular test results (such as POLE, mismatch repair and p53), which help decide treatment. A newer 2023 version of the FIGO system also uses these results, so your report may show slightly different sub-stages; ask your doctor to explain yours.

Recommended treatment pathway

When it can be done safely, treatment usually starts with surgery: removal of the womb and cervix, both fallopian tubes and ovaries, a check of the lymph nodes, and removal of any visible cancer outside the womb, so that ideally no visible disease is left. Keyhole (laparoscopic) or robotic surgery may suit selected women, for example when the spread is limited; many women with stage 3 need open surgery. Robotic surgery is available at Sterling Hospitals and KD Hospital; our page on uterine cancer surgery options explains the differences.

If the cancer cannot be removed safely at first, chemotherapy or radiotherapy may be given first and surgery considered later. The plan is agreed for each woman by a team that includes the surgeon, the medical oncologist and the radiation oncologist.

Adjuvant therapy

After surgery, most women with stage 3 are advised chemotherapy, usually carboplatin and paclitaxel, often together with radiotherapy (sikai). What the main trials found, in plain words:

PORTEC-3 (long-term results published in 2019): in women with high-risk endometrial cancer, including stage 3, chemotherapy given during and after pelvic radiotherapy led to better survival than radiotherapy alone, with more side effects.
GOG-258 (published in 2019): in stage 3 and 4A cancer, chemotherapy plus radiotherapy did not keep women free of cancer for longer overall than chemotherapy alone, but it did lower the chance of the cancer coming back in the vagina and pelvic lymph nodes.
RUBY and NRG-GY018 (published in 2023): in advanced (stage 3 or 4) or recurrent cancer, adding the immunotherapy drug dostarlimab or pembrolizumab to chemotherapy delayed the cancer growing again, with the largest benefit in tumours that are mismatch repair deficient (dMMR or MSI-high). These trials included women with stage 3 only in certain situations, for example when cancer was still visible after surgery, not everyone with stage 3.

So the mix of chemotherapy, radiotherapy and immunotherapy is decided for each woman, based on where the cancer was, what was removed, the tumour type, molecular results and her general health. Immunotherapy approvals and availability can differ in India; the team will confirm what applies to you. The combination of lenvatinib and pembrolizumab is mainly used if the cancer comes back or grows after platinum chemotherapy, as studied in the KEYNOTE-775 trial (published in 2022), mostly in tumours that are mismatch repair proficient. Cancers with a POLE mutation usually have a very good outlook.

Outlook

Stage 3 is serious, but many women are treated with the aim of cure. Published series report 5-year survival of about 50-65% with full treatment; results vary widely between the sub-stages and tumour types, and molecular subtyping increasingly guides prognosis. These figures describe large groups of women and cannot predict what will happen to any one person.

FAQs

Where is stage 3 endometrial cancer treatment performed in Ahmedabad?

Dr. Nishtha Tripathi Patel treats this disease stage at Sterling Hospitals (Sindhubhavan), KD Hospital, and Welcare Speciality Hospital in Ahmedabad. Robotic surgery is done at Sterling Hospitals and KD Hospital; Welcare Speciality Hospital offers open and keyhole (laparoscopic) surgery. The hospital is chosen based on the procedure needed and your preference.

What is the typical hospital stay?

After keyhole or robotic surgery, the hospital stay is often about 3–4 days. After open surgery, especially when cancer outside the womb is removed, the stay is usually longer; your surgeon will give you an estimate. Chemotherapy and radiotherapy are usually outpatient treatments: external radiotherapy is usually about 25 sessions over about 5 weeks, with brachytherapy as needed.

Is stage 3 endometrial cancer curable?

For many women, yes: treatment aims at cure, especially when all visible cancer has been removed. For others, treatment aims to control the cancer for as long as possible. The chance depends on the sub-stage, the type and grade of the cancer, molecular results and your general health. Your doctor can explain what your own report means.

What is the likely outcome?

5-year survival 50-65% with optimal multimodality treatment; molecular subtyping increasingly guides prognosis. Outcomes are stage-dependent and individual; the figures above are averages from published series.

Is fertility preservation possible?

Fertility preservation is not standard for this stage. Egg or embryo cryopreservation may be considered before chemotherapy if applicable.

Can I get a second opinion before deciding?

Yes. Share your reports on WhatsApp (+91 76988 00333). Dr. Nishtha provides independent review of stage, pathology, imaging and proposed treatment within 24-48 hours.
