Esophageal cyst producing CA19-9 and CA125.

The patient was a 59-year-old woman in whom computed tomography revealed a posterior mediastinal cyst and ovarian cystoma at a medical check-up in March 2007. Blood tests showed high CA19-9 and CA125 levels. She underwent left adnexectomy for ovarian cystoma in July 2008 and histopathological examination led to a diagnosis of dermoid cyst. The postoperative levels of CA19-9 and CA125 remained h...

Abdominal pain and increased CA19-9.

A 32-year-old man with an unremarkable medical history presented to the ambulatory clinic with complaints of nonlocalized abdominal pain. The results of a physical examination were unremarkable. The results obtained from liver, pancreatic, and renal testing were within the reference intervals, and the results of both a fecal occult blood test and an investigation for parasites in the stool were...

Colorectal Carcinoma with Extremely Low CA19-9

AIM The aim of this study is to determine the significance of postoperative sequential measurements of serum CA19-9 in patients with extremely low serum level. PATIENTS AND METHODS Serum level of CA19-9 of 1096 patients who underwent surgery was measured preoperatively and every three months after surgery for 5 years. Patients with CA19-9 level of less than 2 U/mL at the time of diagnosis wer...

CA19-9 elevation in ovarian mature cystic teratoma: Discrimination from ovarian cancer – CA19-9 level in teratoma

BACKGROUND We aimed to identify clinical characteristics of ovarian mature cystic teratoma (MCT) in association with CA19-9 elevation, and to determine if CA19-9 is a useful marker in discrimination of MCT from ovarian cancer (OC). MATERIAL AND METHODS Medical records of 322 women with pathologically-confirmed MCT or OC (stage 1 or 2) were reviewed retrospectively. The relationships between t...
