Abstract Context.—CDX2, a critical nuclear transcription factor for intestinal development, is expressed in intestinal epithelium and adenocarcinomas. Objectives.—To determine if CDX2 is a useful marker for intestinal-type differentiation and to correlate tumor histology with CDX2 staining in colorectal adenocarcinomas. Design.—Tissue microarrays from 71 colorectal adenocarcinomas, 31 hepatocellular carcinomas, 47 lung adenocarcinomas, 55 squamous cell carcinomas of the lung, 69 neuroendocrine carcinomas of the lung and 43 of the pancreas, 57 pancreatic adenocarcinomas, and 256 endometrial adenocarcinomas were stained with antibody against CDX2. Results.—CDX2 staining was positive in 51 (71.8%) of 71 colorectal cancers, including 38 (74.5%) of 51 well- or moderately differentiated tumors and 13 (65.0%) of 20 high-grade tumors. Of the high-grade tumors, 5 (71.4%) of 7 mucinous, 3 (100%) of 3 signet ring cell, and 5 (50.0%) of 10 poorly differentiated tumors were positive. Other tumors showing occasional CDX2 staining included 1 of 30 well- or moderately differentiated neuroendocrine carcinomas of the lung and 2 of 43 from the pancreas, 1 of 47 lung adenocarcinomas, 3 of 57 pancreatic adenocarcinomas, and 15 of 256 endometrial carcinomas. Hepatocellular, poorly differentiated neuroendocrine carcinoma of the lung and squamous cell carcinomas of the lung were not immunoreactive for CDX2. Conclusions.—CDX2 is a useful marker for intestinal-type differentiation, is rarely seen in tumors from the other sites evaluated, and may be useful in determining the site of origin for some metastatic tumors. However, CDX2 is not a sensitive marker for poorly differentiated colorectal carcinoma.

Aim and background High-grade gastrointestinal neuroendocrine neoplasms, ie, poorly differentiated neuroendocrine carcinomas, with no effective therapeutic approaches, have a high ability to metastasize. Methods A review of the hospital information system was performed. Patients with histologically proven gastrointestinal neuroendocrine carcinoma who were treated with irinotecan combined with 5-fluorouracil and leucovorin in a first-line setting were eligible for analysis. We extracted information on age, sex, disease stage, laboratory findings, radiological findings, pathological findings, chemotherapy, effectiveness and adverse events of therapy, and outcomes. Results Eleven patients were included in the study. Partial response was observed in 7 patients. Median progression-free survival and overall survival were 6.5 (95% CI, 5.1–7.9) and 13.0 (95% CI, 9.8–16.2) months, respectively. No treatment-related deaths occurred. Conclusions The results demonstrated that irinotecan combined with 5-fluorouracil and leucovorin is an active regimen with acceptable toxicity for patients with metastatic high-grade gastointestinal neuroendocrine carcinoma that merits further investigation in prospective trials.

274 Background: Poorly differentiated neuroendocrine carcinoma (PDNEC) is a rare and aggressive disease. No standard regimen has yet been established for advanced PDNEC, although regimens for small-cell lung carcinoma such as irinotecan + cisplatin (IP) or etoposide + cisplatin (EP), are usually adopted. The aim of this study was to investigate the outcomes according to the patient’s characteristics and treatment regimens for patients with PDNEC of the digestive system. Methods: Data was collected from the medical records of patients at 23 hospitals. The selection criteria were as follows: 1) histologically proven PDNEC, small cell carcinoma, mixed endocrine-exocrine carcinoma with a PDNEC component, or histologically proven neuroendocrine tumor with rapidly progressive clinical course; 2) primary tumor arising from the gastrointestinal tract (GI) or the hepato-biliary-pancreatic system (HBP); and 3) inoperable or recurrent disease treated with systemic chemotherapy between April 2000 and March 2011. Results: There were 258 patients (pts). The median age was 62.5 years (range, 26-81); male/female, 182/76 pts; the primary site was the esophagus/stomach/small bowel/colorectum/hepato-biliary system/pancreas in 85/70/6/31/31/35 pts. According to these primary sites, the median overall survival period (mOS) was 13.4/13.3/29.7/7.6/7.9/8.5 months, respectively. The most commonly used regimen was IP (160 pts, 62%), followed by EP (46 pts, 18%). For the patients treated with IP/EP, the response rates (RR) were 50%/27%, the progression free survival periods (mPFS) were 5.2/4.0 months, and mOS were 13.0/7.3 months. The subgroup outcome data for patients with HBP or GI cancers are shown in Table. A multivariate analysis demonstrated that a primary HBP cancer (HR=1.96, p=0.002), and a poor PS (HR=2.33, p=0.01) were independent unfavorable prognostic factors. Conclusions: PDNEC of the HBP has a poorer prognosis than GI. IP was the most commonly selected treatment regimen, and seemed to have a favorable treatment outcome. [Table: see text]
