Abstract
Background
There are currently no available biomarkers for advanced pleural mesothelioma that determine which patients could benefit from a specific chemotherapy regimen.
Methods
Based on the results of a previously published phase II study, we associated the 99mTechnetium-labelled liposomal doxorubicin (99mTc-LD) uptake value (75 % cut-off) with the response rate, progression-free survival and overall survival of patients treated with a combination of liposomal doxorubicin and cisplatin.
Results
Patients with tumours exhibiting increased 99mTc-LD uptake showed better response rates, progression-free survival and overall survival than those exhibiting lower uptake 73.3 versus 15 % (p < 0.001); 6.9 versus 3.2 months (p = 0.033) and 23 versus 6.6 months (p = 0.001), respectively.
Conclusion
99mTc-DL uptake in tumour tissue could define a set of patients who would benefit from this chemotherapy regimen.
