Alpha-fetoprotein-producing recurrent nasopharyngeal carcinoma: A case report.

ABSTRACT: Alpha-fetoprotein hardly increased due to nasopharyngeal cancer. In this article, we reported a 57-year-old male nasopharyngeal carcinoma patient who had posttreatment subscapular metastasis with high serum alpha-fetoprotein but negative plasma Epstein-Barr virus DNA. Pathology results indicated that the scapular mass was undifferentiated non-keratinizing carcinoma originated in the nasopharynx. Moreover, no liver lesion was detected by imaging examination. In view of the positive alpha-fetoprotein and alpha-fetoprotein messenger RNA staining result in the right scapular mass fine needle aspiration biopsy sample, we considered the diagnosis of alpha-fetoprotein-producing nasopharyngeal carcinoma that had never been reported before.

Project description:AimTo investigate clinicopathological features of early stage gastric cancer with enteroblastic differentiation (GCED).MethodsWe retrospectively investigated data on 6 cases of early stage GCED and 186 cases of early stage conventional gastric cancer (CGC: well or moderately differentiated adenocarcinoma) who underwent endoscopic submucosal dissection or endoscopic mucosal resection from September 2011 to February 2015 in our hospital. GCED was defined as a tumor having a primitive intestine-like structure composed of cuboidal or columnar cells with clear cytoplasm and immunohistochemical positivity for either alpha-fetoprotein, Glypican 3 or SALL4. The following were compared between GCED and CGC: age, gender, location and size of tumor, macroscopic type, ulceration, depth of invasion, lymphatic and venous invasion, positive horizontal and vertical margin, curative resection rate.ResultsSix cases (5 males, 1 female; mean age 75.7 years; 6 lesions) of early gastric cancer with a GCED component and 186 cases (139 males, 47 females; mean age 72.7 years; 209 lesions) of early stage CGC were investigated. Mean tumor diameters were similar but rates of submucosal invasion, lymphatic invasion, venous invasion, and non-curative resection were higher in GCED than CGC (66.6% vs 11.4%, 33.3% vs 2.3%, 66.6% vs 0.4%, 83.3% vs 11% respectively, P < 0.01). Deep submucosal invasion was not revealed endoscopically or by preoperative biopsy. Histologically, in GCED the superficial mucosal layer was covered with a CGC component. The GCED component tended to exist in the deeper part of the mucosa to the submucosa by lymphatic and/or venous invasion, without severe stromal reaction. In addition, Glypican 3 was the most sensitive marker for GCED (positivity, 83.3%), immunohistochemically.ConclusionEven in the early stage GCED has high malignant potential, and preoperative diagnosis is considered difficult. Endoscopists and pathologists should know the clinicopathological features of this highly malignant type of cancer.
