System and method for evaluating tumor stability

A device for identifying a-size doubling numbers (SDNs) of a clinical lesion relative to a predetermined size of the clinical lesion, the device comprising:

• a planar surface including a first planar surface end, the planar surface extending longitudinally aft from the first planar surface end to a second planar surface end;
• the planar surface defining a data portion first end that is adjacent the first planar surface end, and a data portion extending longitudinally aft from the data portion first end to a data portion second end,
• wherein the data portion includes data zones, including:
• a first zone defining a first zone first end that is adjacent the data portion first end, the first zone extending longitudinally aft from the first zone first end to a first zone second end,
• wherein:
• the first zone defines first zone arcs, the first zone arcs being distributed in a concentric configuration,
• the first zone arcs defining first mutually unique radiuses R1, ranging from a first minimum radius R1min of a first zone first arc to a first maximum radius R1max of a first zone last circle, and
• wherein a concentric center of the first zone arcs is adjacent the first zone first end;
• the first zone arcs are successively larger from each other by a predetermined multiplication factor;
• the first zone includes first zone size markers, respectively positioned adjacent ones of the first zone arcs, and the first zone size markers respectively identify the size doubling numbers (SDNs) of the clinical lesion having a size that corresponds to a respective one of the first zone arcs,
• wherein the device further includes:
• a slider configured to slide longitudinally along the planar surface, the slider defining a laterally extending marker,
• wherein a size measurement of the clinical lesion is obtained by positioning the laterally extending marker so that it laterally extends as a tangent from one of the first zone arcs corresponding to a size of the clinical lesion to a respective one of the second zone size markers,
• the first zone arcs are laterally aligned and longitudinally spaced apart from each other within the first zone, between the concentric center and the first zone second end;
• and
• the first zone first arc represents 2{circumflex over ( )}n1 volume doublings relative to a single tumor cell of the clinical lesion, and the first zone last arc represents 2{circumflex over ( )}m1 volume doublings relative to the single tumor cell, where m1=n1+c1, wherein c is the number of circles in the first zone arcs, and
• wherein n1=30, and c1=10 or greater;
• an electronics housing connected to the slider;
• an electronics controller within the slider housing;
• a motion sensor operationally connected to the electronics controller and configured to sense an extent of longitudinal movement along the device, wherein the longitudinal movement is proportional to a size of the clinical lesion being measured,
• and one or more of:
• a slider display on the slider housing that is operationally connected to the electronics controller, wherein the electronics controller, responsive to the sensing, is configured to control the slider display to provide display indicia indicative of the one or more of radius R, area A and volume V, radius doubling number, area doubling number and volume doubling number of the clinical lesion being measured;
• and
• a remote display, in wireless communication with the electronics controller, wherein the electronics controller, responsive to the sensing, is configured to control the remote display to provide display indicia indicative of the one or more of radius R, area A and volume V, radius doubling number, area doubling number and volume doubling number of the clinical lesion being measured.
