Fifty-two previously untreated patients with advanced non-small-cell lung cancer (NSCLC) were treated on a 14 day cycle with cisplatin (60 mg m-2 i.v.) and vindesine (3 mg m-2 i.v.) on day 1,...

Immunohistochemical staining of desmosomal components in oral squamous cell carcinomas and its association with tumour behaviour.

Hiraki, A., Shinohara, M., Ikebe, T., Nakamura, S., Kurahara, S., Garrod, D. R.

Desmosomes are intercellular junctions that have been shown to be down-regulated in certain types of carcinomas and that may play a role in suppression of invasion and metastasis. We have shown...
