Abstract: Anthracycline derivatives are suitable for use in cancer therapy and diagnosis. These anthracycline derivatives can be radiolabelled and used as an imaging agent in cancer diagnosis. The radiolabelled anthracycline derivatives can also be used together with a drug delivery system, in particular including a two-step targeting strategy, for treating solid and disseminated tumors. These drug delivery system can advantageously be used for treatment and diagnosis of breast cancer.

Abstract: The present invention relates to new anthracycline derivatives and their use in cancer therapy and diagnosis. These anthracycline derivatives can be radiolabelled and used as an imaging agent in cancer diagnosis. The radiolabelled anthracycline derivatives can also be used together with a drug delivery system, in particular including a two-step targeting strategy, for treating solid and disseminated tumours. These drug delivery system can advantageously be used for treatment and diagnosis of breast cancer.

Abstract: The present invention relates to a drug delivery system with two-step targeting, which comprises a combination: (a) a lipid carrier provided with cell targeting agent(s) to target the drug delivery system to specific cells or tissues; and (b) a drug enclosed in said lipid carrier and provided with a DNA targeting agent to target the drug to the nuclei of specific target cells. Furthermore, the invention relates to a method of cancer therapy in which the above drug delivery system is administered to a cancer patient. The goal is to treat or analyse both large tumour masses as well as small tumour cell clusters and single spread tumour cells. According to the invention, drug uptake in tumours will be markedly increased at the same time as the interaction of the drug with healthy organs and tissues can be minimized. The invention gives potential to convert palliative into curative treatment.
