Current chemotherapies for cancer are mostly cytotoxics with serious side effects and high incidence of drug resistance. |
Like tiny divining rods, these drugs hunt down only diseased cells, avoiding the shotgun approach of past chemotherapies. |
However, even aggressive combination chemotherapies ultimately lose their effectiveness against lymphatic tumors, as the cancer becomes resistant to chemotherapy. |
The most common effects of toxicity from chemotherapies for advanced colorectal cancer are diarrhoea, mucositis, asthenia, and neutropenia. |
