Gastric-type Mucinous Carcinoma with an Abnormal Increase of CA199: A Case Report and Literature Review
Abstract
ObjectiveGastric-type mucinous carcinoma (GAS), as a rare subtype of mucinous adenocarcinoma, accounts for approximately 1%–3% of cervical adenocarcinoma. It was considered as a new type of cervical mucinous adenocarcinoma by the World Health Organization (WHO) in 2014. GAS represents more aggressive disease than does usual type endocervical adenocarcinoma (UEA).Case reportA case of cervical adenocarcinoma with an abnormal increase of CA199 in a 50-year-old Chinese woman was reported. Our patient presented with abnormal vaginal discharge and combined with elevated Ca199 at the value of 2,729 U/mL. Imaging examinations showed no abnormalities. Diagnostic conical resection suggested cervical adenocarcinoma in situ. Post-operative pathology confirmed mucinous cervical adenocarcinoma (considering gastric type), infiltrating cervical interstitial >2/3, involving the deep myometrium, accompanied by vascular carcinoma infiltration and lymph node metastasis.The patients received an extensive hysterectomy and post-operative adjuvant chemoradiotherapy. The chemotherapy regimen was paclitaxel, combined with platinum. After 20 months of follow-up, the patient showed no signs of recurrence.ConclusionPreoperative diagnosis of cervical adenocarcinoma is insidious and can be easily misdiagnosed. For patients with high preoperative Ca199, the possibility of GAS should be kept open.
