US 12,728,263 B2 · Delivering tumor treating fields (TTFields) to the neck, thoracic spine, and optic tract

Abstract

During Tumor Treating Fields (TTFields) therapy, one or more pairs of electrode assemblies are used to impose an alternating electric field to the tumor. However, when the cancer cells are distributed among two or more different locations within the subject's body, it can be difficult to achieve sufficient field intensities in all of the different locations. By positioning one pair of electrode assemblies on the left half of the subject's scalp and the right side of the subject's posterior thorax, and positioning another pair of electrode assemblies on the right half of the subject's scalp and the left side of the subject's posterior thorax, it becomes possible to achieve sufficient field intensities in the following three locations simultaneously: (i) an upper half of the subject's thoracic spine, (ii) the subject's cervical spine, and (iii) the subject's head.

Dependent claims

A method of treating one or more tumors in a subject's body located in at least one of

(i) an upper half of the subject's thoracic spine,
(ii) the subject's cervical spine, and
(iii) the subject's head, the method comprising:
(a) applying an alternating voltage between at least one first electrode element affixed to a left half of the subject's scalp and at least one second electrode element affixed to a right side of the subject's posterior thorax;
(b) applying an alternating voltage between at least one third electrode element affixed to a right half of the subject's scalp and at least one fourth electrode element affixed to a left side of the subject's posterior thorax;
and
repeating step (a) and step (b) in an alternating sequence at least 10 times.

A method of treating one or more tumors in a subject's body located in at least one of

(i) an upper half of the subject's thoracic spine,
(ii) the subject's cervical spine, and
(iii) the subject's optic tract, the method comprising:
affixing at least one first electrode element to a left half of the subject's scalp;
affixing at least one second electrode element to a right side of the subject's posterior thorax;
affixing at least one third electrode element to a right half of the subject's scalp;
affixing at least one fourth electrode element to a left side of the subject's posterior thorax;
and
repeating, in an alternating sequence (a) applying an alternating voltage between the at least one first electrode element and the at least one second electrode element, and (b) applying an alternating voltage between the at least one third electrode element and the at least one fourth electrode element,
wherein the repeating is performed after the affixing of the at least one first electrode element, the at least one second electrode element, the at least one third electrode element, and the at least one fourth electrode element.
