Oral administration of systemic anticancer therapy

Definition

The term ‘oral anticancer medicine’ is used to refer to drugs with direct antitumour activity, administered via the oral route to cancer patients, including traditional cytotoxic chemotherapy (e.g. capecitabine, vinorelbine), small molecule treatments (e.g. imatinib, erlotinib) and teratogenic agents such as thalidomide. It does not include hormonal therapies such as tamoxifen or anastrazole (BOPA [16], NPSA [167]). See Table 23.4.
