Taxol And Avastin
Yes it is an option: The standard therapy for ovarian cancer initially is still a taxane (usually Taxol) and Carboplatin. However, Abraxane is an effective taxane down the line for recurrences, and is potentially less toxic. Avastin (bevacizumab) has been combined safely with Abraxane and the two may be helpful for recurrence management. But the question is a bit difficult to answer concretely because circumstances differ. ...Read more
Not really: Abraxane is a derivative of Taxol.

Biologic Therapy: Herceptin/trastuzumab is an antibody to a cell surface proteint coded for by the her2neu gene. Its present in some normal cells but in a subset of breast cancers (10-15%) there are multiple copies of the gene producing large amounts of the protein. The herceptin/trastuzumab antibody binds to that protein and reduces that aggressive nature of her2+cancer. It is usually given with chemo. ...Read moreSee 2 more doctor answers

Why has the drug temozolomide replaced the combination of procarbazine, carmustine and vincristine?

Kills cancer cells!: Taxol (paclitaxel) works by preventing cancer cells from reproducing themselves. In the picture you can see green "microtubules" that are pulling a cancer cell apart into two daughter cells. Taxol blocks microtubules, preventing them from being able to pull the cancer cell into two daughter cells. The cancer cell gets stuck trying to divide, and it dies. Taxol works for many cancer types. ...Read moreSee 1 more doctor answer
Identical: Data on Bevacizumab or Erbitux in patients with metastatic colorectal cancer, patients who do not have a KRAS 12/13 gene mutation, have nearly identical survival rates. These identical results were seen after chemotherapy, where survival with chemo alone was about 5 months vs. 7-8 months using either bevacizumab (Avastin) or cetuximab (Erbitux). ...Read more
While gefitinib was: Developed first, it is hard to find in america (iressa (gefitinib)). Erlotinib (tarceva) has more side effects, but a trial showed a survival advantage. Probably more related to the characteristics of the study participants than the drug. These are small molecule, tyrosine kinase inhibitors in the erb family of receptors. Canada and europe has iressa (gefitinib). Erlotinib is in us. ...Read moreSee 1 more doctor answer

Gem for taxotere (docetaxel): Short answer is no. It cannot be substituted. Now depending upon the underlying cancer whether lung, breast, pancreatic or any other primary solid tumor, one can use taxol, Abraxane or Navelbine (vinorelbine) (they are taxanes like taxotere). If we want to move to a different agent altogether, then Gemzar or a no of other drugs would be available depending upon what the primary tumor is. ...Read more
