Clinicopathologic and Molecular Characteristics of Lung Adenocarcinoma Arising in Young Patients

Kim L, Kim KH, Yoon YH, Ryu JS, Choi SJ, Park IS, Han JY, Kim JM, Chu YC

Lung cancer rarely occurs in young patients. Recent studies have demonstrated that epidemiologic data are closely correlated to some molecular characteristics. We investigated the clinicopathologic characteristics of lung adenocarcinoma in...

Clinicopathologic characteristics of mucinous gastric adenocarcinoma

Hyung WJ, Noh SH, Shin DW, Yoo CH, Kim CB, Min JS, Lee KS

There has been considerable controversy over the prognosis of mucinous gastric enocarcinoma (MGC). In this study we analyzed the clinicopathologic fferences between MGC and non-mucinous gastric carcinoma (NMGC)....

Expression of cyclin dependent kinase inhibitor p21WAF1 alone and in combination with p27KIP1 shows prognostic value in gastric carcinoma

Jang SJ, Ahn MJ, Paik SS, Kong G, Keum JS, Park YW, Lee JD

Evidence suggests that multiple molecular events, including alteration of cell cycle regulators are involved in the development and progression of gastric carcinoma. Recently, it has been reported that the...

Cyclooxygenase 2 in Gastric Carcinoma Is Expressed in Doublecortin- and CaM Kinase-Like-1-Positive Tuft Cells

Mutoh H, Sashikawa , Sakamoto H, Tateno T

BACKGROUND/AIMS: Doublecortin and CaM kinase-like-1 (DCAMKL1) is a marker of stem cells expressed predominantly in the crypt base in the intestine. However, DCAMKL1-positive cells have been shown to be differentiated...
