Long-term complete remission of oral cancer after anti-neoplastic chemotherapy as single treatment modality: role of local chemotherapy.

The impact of intra-arterial local chemotherapy on squamous cell carcinomas of the oral cavity is doubtful when considering long-term survival, especially in cases of nodal involvement. But even in patients with strictly local disease it is not possible to determine the effect of intra-arterial chemotherapy because it is mainly used as a neoadjuvant treatment modality. In the present paper, long-term courses of two patients are described who refused any further treatment after one cycle of intra-arterial chemotherapy with cisplatin followed by systemic chemotherapy with 5-fluorouracil and one cycle of intra-arterial chemotherapy with high-dose cisplatin, respectively. The aim of the paper is to demonstrate the potential of local chemotherapy in responders. The impact of this treatment modality in incurable patients is discussed, too. This may offer a point in favor of use of intra-arterial chemotherapy in combination treatment regimens.
