Summary of the results of allelic status in ovarian serous tumors. Each panel represents a group of serous tumors: SBT, noninvasive MPSC, invasive MPSC, and conventional serous carcinoma. Chromosomal arms in which the SNP markers are located are indicated on the left of each panel. In the vertical columns, each column represents one case. Black squares represent chromosomal arms in which allelic imbalance is identified based on the digital SNP analysis, while gray squares represent chromosomal arms in which both alleles were in balance. Blank squares indicate chromosomal arms that cannot be evaluated because the allelic ratio in the SPRT analysis does not achieve a statistical significant difference or because all SNP markers tested are uninformative in the normal tissue. The very small conventional serous carcinomas (maximal dimension 0.6 and 0.7 cm) are marked with asterisks.
