Colon cancer during pregnancy

Pregnancy affects the clinical presentation, evaluation, treatment, and prognosis of colon cancer

Colon cancer that occurs during pregnancy is often diagnosed at an advanced stage due to confusion of some of the cancer symptomssuch as rectal bleeding, nausea and vomiting, and constipation, with the symptoms of a normal pregnancy.

In addition, in the event that there is any suspicion of the existence of colon cancer, Possible risks to the fetus from diagnostic tests also delay your diagnosis.

Detection and treatment of colon cancer in pregnancy

Evaluation of colon cancer usually includes:

  • Abdominal computed tomography to detect intraperitoneal extension and metastases, however this test is contraindicated during pregnancy, especially during the first trimester, due to the radiation teratogenicity.
  • Similarly, a colonoscopy, which is the standard procedure to evaluate the possible existence of colon cancer, not considered an established procedure during pregnancy due to fetus safety.

With respect to Colon Cancer Treatments During Pregnancy numerous doubts are also raised, since the great most of these therapies can be harmful for the developing fetus. For example:

  • A laparotomy for colon cancer during the first weeks of pregnancy is beneficial for the mother, but can be harmful to the fetus.
  • The same goes for the chemotherapy wave radiotherapy, two treatments that may be beneficial to the mother, can be highly harmful to the fetus.

Therefore, colon cancer therapy during pregnancy must be modified to avoid radiation teratogenicity and to minimize the fetal risks of surgery and chemotherapy.
