IL2 and cervical cancer: A recent paper by Bellone et al., have reported that a substantially higher proportion of cervical cancer cells lines either established from fresh tumors or commercial ones (including CasKi, SiHa, HeLa and C33A which are negative by immunochemistry) express the receptor when evaluated by flow-cytometry and are growth inhibited when incubated with trastuzumab or trastuzumab plus IL-2 [25].
