The leading subtype of lung cancer, adenocarcinoma, received a new classification in 2011 when multifocal, pneumonic-type mucinous tumors, formerly called mucinous bronchioloalveolar carcinomas, were reclassified as %26quot;invasive mucinous adenocarcinomas.%26quot; These tumors appear to be less sensitive to chemotherapy than other non-small cell lung cancers. We herein report two cases of invasive mucinous adenocarcinoma that showed a dramatic radiologic response to combination therapy with cisplatin, pemetrexed and bevacizumab. Recent data suggest that the use of paclitaxel-based chemotherapy is an acceptable therapeutic strategy in cases of invasive mucinous adenocarcinoma. The cases reported here and preclinical findings suggest the therapeutic efficacy of cisplatin, pemetrexed and bevacizumab in treating such tumors.
