Gens Key - Mesothelioma Chemotherapy Response

It is often treated with multiple modalities, including chemotherapy.In a phase II trial involving 78 mesothelioma patients treated with gemcitabine, half showed a complete or partial response to the drug.In four cases, the mesothelioma spread while the patient was on gemcitabine.To determine why some mesothelioma cases respond well to gemcitabine and others do not, the Slovenian team tested the cells of another 107 mesothelioma patients treated with a gemcitabine-platinum mix.In a summary of their results, the Slovenian team concluded that, polymorphisms and haplotypes do appear to influence the efficacy and toxicity of gemcitabine and "should be validated as potential markers for the prediction of clinical outcome in patients with malignant mesothelioma.Of the different genetic arrangements studied, two had no influence on treatment outcomes, one appeared to significantly decrease overall survival probability, two decreased the odds of experiencing nausea and vomiting and others were associated with better or worse tumor
responses.As more is understood about the impact of genetics on medication response, chemotherapy for cancers like mesothelioma.But others had little or no response or experienced serious side effects.

Cell samples were tested for 11 different polymorphisms or genetic anomalies as well as haplotypes (particular combinations of DNA sequencing) that might influence response to gemcitabine.Now, a team of biochemists in Slovenia are studying genetically-linked responses to the chemotherapy drug gemcitabine, a nucleoside analog that some studies have found to be a promising alternative to the more conventional cisplatin-pemetrexed combination for mesothelioma.Mesothelioma is a fast-growing cancer triggered by exposure to asbestos.If further studies support the findings, doctors may eventually be able to test for gemcitabine compatibility and take some of the guesswork out of mesothelioma treatment selection.

Research being performed in Eastern Europe may eventually help doctors around the world predict which mesothelioma patients will respond best to a particular type of chemotherapy.It is often treated with multiple modalities, including chemotherapy.As more is understood about the impact of genetics on medication response, chemotherapy for cancers like mesothelioma is moving away from a ‘one-size-fits-all' approach to a more tailored approach based on individual cellular characteristics.
