A 32-year-old primigravida at 26 weeks of gestation presented with rectal bleeding and was diagnosed with stage T4bN+M0 rectal adenocarcinoma. Despite the conventional recommendation of pregnancy termination in such circumstances, the patient expressed a strong desire to continue the pregnancy. A multidisciplinary team comprising colorectal surgeons, medical oncologists, radiation oncologists, and maternal-fetal medicine specialists developed a unified and coordinated treatment plan.
