Our patient supports the proposition that somatic mutation L858R in exon 21 of the EGFR gene accounts for complete responsiveness to gefitinib in a Taiwanese female patient with metastatic adenocarcinoma of lung.
In positive-stained cases, GATA3 stained more tumor cells than GCDFP15 (79% versus 25% for intraepithelial disease, 71% vs 34% for invasive adenocarcinoma, 73% vs 50% for metastatic adenocarcinoma, p < 0.01 for all 3 components).
Patients with histologically confirmed metastatic adenocarcinoma of the colon or rectum were enrolled into a UGT1A1 genotype-directed dose-escalation trial of irinotecan plus fixed-dose capecitabine (2,000 mg/m(2)/day).
Sarcomatous transformation of EGFR and TP53 mutation-positive metastatic adenocarcinoma of the lungs, masquerading as a primary pleomorphic sarcoma of the proximal femur.
Patients with mutant KRASmetastatic adenocarcinoma of the colon or rectum refractory to fluoropyrimidine- and oxaliplatin-based chemotherapy were randomized 1 : 1 : 1 to receive intravenous FOLFIRI plus conatumumab 10 mg/kg (Arm A), ganitumab 12 mg/kg (Arm B), or placebo (Arm C) Q2W.
An antibody panel including TTF-1 and Napsin-A or a dual stain will be very helpful in determining the origin of metastatic adenocarcinoma in serous effusion.
The utility of combination with CK5/6, IMP3 and TTF1 to differentiate among reactive mesothelial cells (RMs), metastatic adenocarcinoma of lung (LAC) and non-lung (NLAC) origin was investigated by using immunocytochemistry (ICC) and conventional PCR (C-PCR) in pleural effusion.
Patients with locally advanced or metastatic adenocarcinoma or TTF-1 (+) NSCLC, positive EGFR sensitive mutation, and EGFR-TKI reuse after initial EGFR-TKI followed by chemotherapy were enrolled.
We aim to evaluate the role of GATA3 in determining the breast origin of metastatic adenocarcinoma in malignant effusions using immunohistochemistry on cell-block microarray in comparison with ER and PR results.
Patients with locally advanced or metastatic adenocarcinoma or TTF-1 (+) NSCLC, positive EGFR sensitive mutation, and EGFR-TKI reuse after initial EGFR-TKI followed by chemotherapy were enrolled.

Phase I trial of a recombinant vaccinia virus encoding carcinoembryonic antigen in metastatic adenocarcinoma: comparison of intradermal versus subcutaneous administration.
We describe the morphologic findings in order to heighten awareness that CD30+ ALCL may mimic metastatic adenocarcinoma in a body fluid or bronchial brushing and should be considered in the differential diagnosis.
An antibody panel including TTF-1 and Napsin-A or a dual stain will be very helpful in determining the origin of metastatic adenocarcinoma in serous effusion.
Trastuzumab in combination with capecitabine or 5-fluorouracil and cisplatin is approved by the European Medicines Agency for the treatment of patients with human epidermal growth factor receptor 2 (HER2)-positive (immunohistochemistry 3+ or immunohistochemistry 2+/fluorescence in situ hybridization-positive or immunohistochemistry 2+/silver in situ hybridization-positive) metastatic adenocarcinoma of the stomach or gastro-esophageal junction.
A high index of suspicion and ancillary testing, including P16 immunostaining and molecular genetic testing for HPV, is required to properly diagnose and subclassify HPV-related endocervical adenocarcinoma metastatic to the ovary.

We utilized a new anti-MYC antibody coupled with genetically defined control experiments to localize MYC protein within human tissue microarrays consisting of normal, atrophy, PIN, primary adenocarcinoma, and metastatic adenocarcinoma.
