Ovarian Cancer: 19 ovarian tumors of diverse histologic type vs. pool of all 19 tumors

Transcriptional profiling of 19 ovarian tumors of 5 distinct histologic types (serous, endometrioid, clear cell, mucinous and small cell), to investigate similar and distinct biology associated with each histologic type. RNA from fresh-frozen ovarian tumor samples were individually hybridized to a pooled RNA from all 19 tumor cases
