Hereditary common cancers: molecular and clinical genetics.
2001
This review focuses on the functional role and structural features of the genes involved in common hereditary cancers. Most of these tumors are sporadic and the genetic alterations responsible for their genesis take place over several cell generations; nevertheless, 5 to 10% of the human tumors are hereditary, with a rapid development. Cancer susceptibility genes have been classified as "gatekeepers" (e.g. RB1, ki-ras) and "caretakers" (e.g. hMLH1 and hMSH2, BRCA1). The first step in identifying individuals at high risk of developing a specific inherited form of cancer, and who should therefore undergo genetic tests, is the detailed construction of family history (an accurate cancer family …
Prognostic significance of DNA ploidy, S-phase fraction, and tissue levels of aspartic, cysteine, and serine proteases in operable gastric carcinoma
2000
A consecutive series of 63 untreated patients undergoing surgical resection for stage I-IV gastric adenocarcinomas (GCs) has been prospectively studied. Our purpose was to analyze the predictive relevance of DNA ploidy, S-phase fraction (SPF), and tissue levels of lysosomal proteinases cathepsin D (CD), cathepsin B (CB), cathepsin L (CL), and urokinase-type plasminogen activator (uPA) and that of the intracellular cysteine proteinase inhibitor stefin A on clinical outcome. All of the patients taking part in this study were followed up for a median of 73 months. DNA aneuploidy was present in 71% of the cases (45/63), whereas 9% of these (4/45) showed multiclonality. Both DNA ploidy and SPF w…
