Beyond the limits, extreme minimally invasive surgery in invasive thymic tumours

Generally accepted indications for minimally invasive surgery (MIS) approach to thymic tumours include small, well encapsulated non-invasive tumours. MIS for more advanced complicated thymic tumours remain controversial. This is due to concerns on whether an oncologically complete resection can be done. However with increased experience MIS can be used safely in a selected group of complex thymic tumours without oncological compromise.
