The pathogenesis of primary carcinoma of the fallopian tube (PCFT) is poorly understood. Tumor suppressor p53 gene alterations are common in human malignancies, but their role in the tumorigenesis and survival of PCFT is undefined. The objectives of this study were to define the occurrence and prognostic role of p53 alteration in PCFT and to examine the efficiency of immunohistochemistry (IHC) in...
Forty-two cases, including 21 uterine papillary serous carcinomas (UPSC) and 21 age-, nuclear-grade-, and clinical-stage-matched uterine endometrioid carcinomas (UEC), were studied immunohistochemically for p53 and bcl-2 in archival paraffin-embedded tissue. Compared to UEC (28.6% positive), UPSC (71.4% positive) had a significantly higher frequency of p53 overexpression (P= 0.005); furthermore, in...
