Can Endometrial Cancer Occur During Pregnancy?

Yes, endometrial cancer can occur during pregnancy, but it is extremely rare.

Because abnormal bleeding and pelvic symptoms can sometimes be attributed to pregnancy-related changes, diagnosis may be delayed.

The approach depends mainly on the type and grade of cancer, stage of disease, depth of invasion, gestational age, and the patient’s wishes regarding continuation of pregnancy.

In selected patients with early-stage, low-grade endometrial cancer, pregnancy may sometimes be continued with very close monitoring and definitive cancer treatment planned after delivery.

However, this is not appropriate for every patient. More advanced or aggressive cancer may require treatment that cannot safely be delayed.

Management should involve a gynecologic oncologist, maternal-fetal medicine specialist, obstetrician and, when appropriate, a neonatology team.

Pregnancy is a time of joy and anticipation, but it can also be a period of uncertainty and worry, especially when faced with a diagnosis like endometrial cancer.

As a Endometrial cancer surgeon in Mumbai, I understand the concerns and questions that may arise when dealing with this rare and challenging situation.

What is Endometrial Cancer?

Endometrial cancer is a type of cancer that affects the lining of the uterus, called the endometrium. While it is most commonly diagnosed in postmenopausal women.

Only 5 % of endometrial cancers occur in women younger than 40 years. 

The diagnosis of endometrial cancer in pregnancy is very rare. However, the scenario  is particularly challenging due to concerns about the safety of the fetus.

How Rare Is Endometrial Cancer During Pregnancy?

 Endometrial cancer during pregnancy is exceptionally uncommon because endometrial cancer is primarily diagnosed later in life, while pregnancy usually occurs at a younger age.

When endometrial cancer is diagnosed in a young woman, it may be associated with factors such as obesity, prolonged exposure to estrogen without progesterone, polycystic ovary syndrome, diabetes, hereditary cancer syndromes such as Lynch syndrome, or a history of endometrial hyperplasia.

Importantly, being pregnant does not mean that abnormal bleeding or pelvic symptoms should automatically be considered normal.

Persistent or unusual symptoms require appropriate medical evaluation.

Can Pregnancy Make Endometrial Cancer Worse?

Pregnancy changes hormone levels significantly, which raises an important question about whether pregnancy can accelerate endometrial cancer.

There is no simple answer that applies to every patient. The biological behaviour of the cancer depends on its histological type, grade, hormone-receptor status, stage and other tumour characteristics.

Some early-stage, low-grade endometrial cancers are hormone-sensitive and may remain relatively stable during pregnancy, allowing carefully selected patients to continue the pregnancy under specialist supervision.

However, this does not mean that pregnancy is a treatment for cancer or that cancer progression cannot occur.

The decision to continue a pregnancy after an endometrial cancer diagnosis should therefore be made after detailed assessment by a gynecologic oncologist and maternal-fetal medicine team.

How is Endometrial Cancer Diagnosed During Pregnancy?

The symptoms of endometrial cancer, such as abnormal vaginal bleeding or pelvic pain, may be mistaken for pregnancy-related issues. However, if these symptoms persist or are severe, it is essential to consult with a healthcare provider.

Endometrial cancer in pregnancy is usually diagnosed 

1. During miscarriage 
2. When there is persistent vaginal bleeding due after delivery
3. During Work up for infertility 
4. and patient has turned pregnant accidentally while waiting for test results

 MRI is the investigation of choice when there is a live fetus in the uterus. However the findings may be confusing due to pregnancy related changes.

Potential Risks and Complications

The diagnosis of endometrial cancer during pregnancy raises concerns about the health of both the mother and the baby. Potential risks and complications include:

• Preterm birth:
  

  Some treatments for endometrial cancer may increase the risk of preterm birth, which can result in various health problems for the baby.

• Low birth weight:
  

  Babies born to mothers undergoing treatment for endometrial cancer may have a lower birth weight, which could lead to developmental issues.

• Miscarriage:
  

  In some cases, the treatment of endometrial cancer during pregnancy may increase the risk of miscarriage.

Can Pregnancy Be Continued After an Endometrial Cancer Diagnosis?

In selected cases, pregnancy may be continued after an endometrial cancer diagnosis, but this depends on the characteristics of the cancer and the health of the mother and baby.

Pregnancy continuation may be considered more carefully when the cancer is:

• Early stage
• Low grade
• Confined to the uterus
• Showing limited or no myometrial invasion
• Considered unlikely to progress rapidly during the pregnancy

Pregnancy continuation may not be appropriate when the cancer is aggressive, advanced, rapidly progressing or requires treatment that cannot safely be postponed.

The decision should be individualized. The medical team must balance the potential benefit of continuing the pregnancy against the risk of delaying definitive cancer treatment.

Treatment Options for Endometrial Cancer During Pregnancy

The treatment of endometrial cancer during pregnancy depends on several factors, including the stage of the cancer, the health of the mother and the baby, gestation age and the personal preferences of the patient.

Due to the rarity of this clinical entity there is no sound scientific proof to guide decisions.

However , it has been observed that the majority of these cancers are low grade and without or with minimal myometrial involvement.  Some possible treatment options include:

• Close monitoring:
  

Pregnancy hormones have the ability to suppress the growth of endometrial cancer. Hence close observation is a valid option when the pregnancy is precious or the patient decides to continue pregnancy. A definitive treatment can be offered after the delivery. The outcomes depend on the type of endometrial cancer and the stage. 

• Surgery:

A surgical procedure called a dilation and curettage (D&C) may be performed to remove the cancerous tissue. However this means the loss of pregnancy. Based on the analysis of removed tissue and other imaging studies, it can be determined if fertility can be preserved for future pregnancy while treating the cancer adequately.

If the disease is advanced , a surgical removal of all the disease with a resultant loss of pregnancy may need to be considered. Similar steps can be taken when a patient decides to terminate pregnancy and get treated for the cancer. 

In some instances removal of only the nodes , without touching the uterus and ovaries can be considered, to determine if chemotherapy is needed to control the tumour while pregnancy can be preserved.

• Chemotherapy:

Chemotherapy may be considered if the cancer has spread beyond the uterus. However, this treatment option carries risks to the fetus and may only be recommended in specific circumstances.

Does Endometrial Cancer Spread to the Baby?

Endometrial cancer does not usually spread directly from the mother to the fetus.

However, the overall health of the mother, the stage of cancer and the treatments required can affect pregnancy outcomes.

The main concerns for the baby are generally related to the mother’s illness, complications of pregnancy and the potential effects of cancer treatment rather than direct transmission of the cancer.

If chemotherapy or another treatment is required during pregnancy, the maternal-fetal medicine and oncology teams will assess the potential risks to fetal development and determine the safest timing and treatment approach.

Next Steps if You Are Diagnosed with Endometrial Cancer During Pregnancy

 Being diagnosed with endometrial cancer during pregnancy can be overwhelming, but it is essential to take proactive steps towards managing the situation. Here are some recommendations on what to do next if you or a loved one has been diagnosed with endometrial cancer during pregnancy:

Frequently Asked Questions About Endometrial Cancer in Pregnancy

1.Is endometrial cancer possible during pregnancy?

Yes. Endometrial cancer can occur during pregnancy, but it is extremely rare.

2.Can a woman with endometrial cancer continue her pregnancy?

Sometimes. Pregnancy continuation may be considered in carefully selected patients with early-stage, low-grade disease when delaying definitive treatment is considered medically acceptable.

3.Does endometrial cancer mean the pregnancy must be terminated?

No. A cancer diagnosis does not automatically mean that pregnancy must be terminated. The decision depends on the cancer type, grade, stage, gestational age, treatment requirements and the patient’s preferences.

4.Is MRI safe during pregnancy?

MRI may be used during pregnancy when clinically necessary because it does not use ionizing radiation. When imaging is required, the medical team determines the most appropriate MRI protocol based on the clinical situation.

5.Can chemotherapy be given during pregnancy?

In selected circumstances, certain chemotherapy treatments may be considered after the first trimester. The decision depends on the cancer and gestational age and must be made by an oncology and maternal-fetal medicine team.

6.Can endometrial cancer spread to the baby?

Direct spread of endometrial cancer to the fetus is extremely uncommon. The greater concerns are usually related to the mother’s cancer, pregnancy complications and potential effects of treatment.

7.What happens if treatment is delayed until after delivery?

The patient requires close monitoring during pregnancy and a clear treatment plan for after delivery. Definitive treatment may then be performed based on the cancer stage and pathology.

8.Can I become pregnant again after endometrial cancer treatment?

Fertility after treatment depends on the treatment received, whether the uterus was preserved and the patient’s individual circumstances. Fertility preservation should be discussed before treatment whenever appropriate.

9.Which specialist treats endometrial cancer during pregnancy?

A gynecologic oncologist should ideally coordinate cancer care together with a maternal-fetal medicine specialist and obstetric team. Additional specialists, including neonatology, may be involved depending on gestational age and treatment needs.
