[New aspects by the therapy of ovarian cancer--What changes after the ASCO-Meeting 2001]

The standard primary therapy of advanced ovarian cancer consists of platinum derivatives in combination with paclitaxel. In a first report presented at this year's meeting of the American Society of Clinical Oncology (ASCO) docetaxel appeared to be as effective as paclitaxel in combination with carboplatin, while the toxicity profile present some advantages. The addition of a third drug to platinum-taxane-combination does not appear to improve the therapeutic index. According to the data of the ICON1- and ACTION-trial, carboplatin containing chemotherapies are associated with a significant benefit also in early ovarian cancer. Platinum-resistant disease remains a therapeutic challenge, since the available drugs display only limited activity of short duration. Some experimental data suggest evidence for a possible therapeutic role of small molecules that inhibit the epidermal growth factor receptor (OSI-774) or antisense oligonucleotides interfering with EGF-receptor signalling (ISIS 5132). Novel classes of chemotherapeutic agents, including the acylfulvenes and the epothilone-analogues warrant further study in this disease. Multimodal therapies combining cytotoxic agents with antibodies against CA 12-5 or metalloproteinase inhibitors have failed to demonstrate any survival benefit in patients with ovarian cancer. Despite significant progress in the last decade ovarian cancer remains the most lethal gynaecologic malignancy in women in most western countries. Further multicenter clinical studies are needed to better define new therapeutic options.
