Abstract
This is a case report of a uterine cancer with the International Federation of Gynecology and Obstetrics staging 3c2 with the initial clinical presentation of postmenopausal vaginal bleeding in August 2015. Endometrium biopsy showed invasive nests of poorly differentiated grade 3 endometrioid adenocarcinoma. The patient received robotic surgery including total hysterectomy, bilateral salpingo-oophorectomy, bilateral pelvic lymph node dissection, para-aortic lymph node dissection, and washing cytology. The final pathology showed an endometrioid carcinoma with myometrium invasion up to 85% and para-aortic and pelvic lymph nodes invasion. The patient received six courses of adjuvant chemotherapy (paclitaxel and carboplatin) with concurrent chemoradiotherapy after the surgery. Later, immunotherapy with Picibanil (OK-432) and interleukin-2 (IL-2) was given, and cancer did not recur for 34 months until tumor recurrence at the liver dome and bilateral lung was noted by positron-emission tomography scan in July 2018. The patient received laparoscopic surgery for intra-abdominal tumor excision in December 2018, and the tumor found extended to the right diaphragm, liver surface, omentum, bilateral flank to pelvic peritoneum, Douglas pouch, and upper rectum. We continued the immunotherapy with OK-432, IL-2, Aldara cream (imiquimod), and later on, virotherapy (human papillomavirus vaccine). The immune risk profiles showed T-cells' proliferation and alteration of the Th1/Th2 activation after immunotherapy and virotherapy. Proctectomy with colon-anal anastomosis and cytoreduction surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) (doxorubicin and paclitaxel) was performed in January 2019. After the surgery, the patient received chemotherapy (topotecan, paclitaxel, lipodox, and carboplatin) and continued the immunotherapy. The immune risk profiles showed CD4, CD4/CD8 increase after HIPEC and immunotherapy. The patient continued the therapy until May 2020.
