This invention relates generally to a combination therapy for the treatment of cancer, particularly to a combination of (i) a bifunctional molecule comprising a TGF?RII or fragment thereof capable of binding TGF? and an antibody, or antigen binding fragment thereof, that binds to an immune checkpoint protein, such as Programmed Death Ligand 1 (PD-L1) and (ii) at least one additional anti-cancer therapeutic agent.

The present disclosure relates to a method and a medical apparatus for visualizing on magnetic resonance (MR) images a hadron beam path traversing an organic body. The present method may utilize artefacts in MR image acquisition provoked by the changes in properties of excitable atoms when irradiated by a hadron beam. By synchronizing the hadron pulses with different steps of MR data acquisition, it is possible to identify such artefacts and determine, based on their positions, the hadron beam path and the corresponding position of the Bragg peak.

Presented systems and methods facilitate efficient and effective monitoring of particle beams. In some embodiments, a radiation gun system comprises: a particle beam gun that generates a particle beam, and a gun control component that controls the gun particle beam generation characteristics, including particle beam fidelity characteristics. The particle beam characteristics can be compatible with FLASH radiation therapy. Resolution control of the particle beam generation can enable dose delivery at an intra-pulse level and micro-bunch level. The micro-bunch can include individual bunches per each 3 GHz RF cycle within the 5 to 15 sec pulse-width. The FLASH radiation therapy dose delivery can have a bunch level resolution of approximately 4.410{circumflex over ()}-6 cGy/bunch.

A method for treating a tumor, comprising identifying a tumor as a pancreatic cancer tumor and implanting in the tumor identified as a pancreatic cancer tumor, as least one diffusing alpha-emitter radiation therapy (DaRT) source (21) with a suitable radon release rate and for a given duration, such that the source (21) provides during the given duration a cumulated activity of released radon between 5.6 Mega becquerel (MBq) hour and 11.6 MBq hour, per centimeter length.

A method for treating a cancerous tumor, by implanting in the cancerous tumor at least one diffusing alpha-emitter radiation therapy (DaRT) source with a suitable radon release rate and for a given duration, such that the source provides during the given duration a cumulated activity of released radon of at least 10 Mega becquerel (MBq) hour, per centimeter length. Optionally, the sources are implanted in an array of sources, each source separated from its neighboring sources in the array by not more than 4.5 millimeters.

A method for treating a tumor, comprising identifying a tumor as a breast cancer tumor and implanting in the tumor identified as a breast cancer tumor, as least one diffusing alpha-emitter radiation therapy (DaRT) source with a suitable radon release rate and for a given duration, such that the source provides during the given duration a cumulated activity of released radon between 3.5 Mega becquerel (MBq) hour and 9 MBq hour, per centimeter length.

A therapeutic device is provided, including a cylindrical gantry; a pedestal, a particle beam irradiation device, a first rail, and a second rail all disposed in the gantry; the first rail including an arc-shaped portion and a straight portion, the second rail having a same shape as the first rail, a rail motor on the second rail to rotate the second rail in a opposite direction than that of the gantry, first and second moving floors on the rails and respectively including first floor panels rotatably connected to each other and second floor panels rotatably connected to each other, a first end panel of the first floor and a fourth end panel of the second floor being detachably connected to the irradiation device, and a second end panel of the first floor being detachably connected to a third end panel of the second floor.

The present disclosure relates to a hadron therapy installation comprising a moving floor in the form of a deformable band guided in a guide structure. The moving floor comprises a lower segment and an upper segment. The lower segment can be pulled by the irradiation unit from a lower docked position to a position in which the lower segment forms a substantially horizontal floor surface when the irradiation unit is in a first angular position. The upper segment can be pulled by the irradiation unit from an upper docked position to a position in which the upper segment at least partially forms the substantially horizontal floor surface when the irradiation unit is in a second angular position. The lower segment and the upper segment may have a finite length and a counterweight further connected to the free end of the upper segment.

The present invention relates to a method to improve the anti-tumour effects of immune checkpoint therapy by combining the use of a checkpoint inhibitor with ultralow dose whole body irradiation. The present invention enhances the anti-tumour effects of immune checkpoint therapy by reducing tumour volume as well as shortening the response time of the immune checkpoint therapy, as compared to immune checkpoint therapy on its own.
