Provided herein are methods of treating a nonhematopoietic malignant tumor in a patient and methods of prognosing a nonhematopoietic malignant tumor in a patient, comprising administering to the patient a therapeutically effective amount of an agent that preferentially kills or inhibits proliferation or activity of leukocytes relative to nonhematopoietic cells.

Methods of treating and prognosing nonhematopoietic malignant tumors

Techniques for determining optimal duration for treatment of disease include receiving an untreated series of measurements and a treated series of measurements. The untreated series indicates temporal progression of a physical property related to a disease while the disease is untreated. The treated series of measurements indicates temporal progression of the physical property of the disease while a particular treatment is administered. A series of effectiveness values is determined based on the untreated and treated series. Each effectiveness value indicates a ratio between an untreated and a treated rate of change of the physical property at a corresponding time. An elapsed time is determined from start of treatment to an earliest time when an effectiveness value reaches an extreme compared to adjacent effectiveness values. Duration for treatment is based on the elapsed time, and is especially useful for each cycle of dose dense regimes for treatments with toxic side effects.

Method for determining disease treatment duration

This invention relates, e.g., to a method for identifying an agent that inhibits a metastatic cell (e.g. that inhibits cancer metastasis), comprising measuring the amount of seeding of a tumor by a detectably labeled, metastatic cell, in a subject, in the presence and absence of a putative agent, wherein the amount of seeding by the metastatic cell is proportional to the metastatic potential of the cell, and wherein a significant amount of inhibition of the seeding by the putative agent indicates that the putative agent is effective to inhibit the metastatic cell (e, g, cancer metastasis). Also described are kits suitable for performing methods of the invention.
