Abstract: A method of treating cancer includes administering a first dose of radiation to a subject; determining a level of a biomarker obtained from the subject, the level indicating an immune response of the subject to the first dose; and not administering a second dose of radiation to the subject unless and until the level of the biomarker is beyond a threshold value.

Abstract: Balloon catheter, applicator, particularly for invasive radiotherapy, and method of controlling the balloon catheter with respect to its shape and position in a tissue to be treated prior to an irradiation. The balloon catheter provides a catheter shaft for introducing a probe, an outer balloon and an inner balloon, disposed inside the outer balloon, the inner space of the inner balloon connecting to a channel for connection to a media inlet and intermediate space between the outer balloon and the inner balloon connecting to a channel for connection to a media storage unit. In order that the balloon catheter can be securely controlled with respect to its shape and position in a patient in a simple but clear manner prior to irradiation, the outer balloon is formed of a flexible, non-extendible material and the inner balloon is formed of a flexible, extendible material.

Abstract: The present invention relates to a balloon catheter (10) as well as an applicator (50), particularly for invasive radiotherapy. The balloon catheter (10) provides a catheter shaft (11) for introducing a probe (40), a first, outer balloon (20) and a second, inner balloon (30), disposed inside the outer balloon (20), the inner space (31) of the second, inner balloon (30) connecting to a channel (32) for connection to a media inlet (41) and intermediate space (21) between the first, outer balloon (20) and the second, inner balloon (30) connecting to a channel (22) for connection to a media storage unit (42). In order that the balloon catheter can be securely controlled with respect to its shape and position in a patient in a simple but clear manner prior to irradiation, it is provided according to the invention that outer balloon (20) is formed of a flexible, non-extendible material and that inner balloon (30) is formed of a flexible, extendible material.
