Repetitive Transcranial Magnetic Stimulation in Cancer Patients With Depression and Anxiety

Inclusion Criteria: * Female * Age 22-80 * Had a previous diagnosis of cancer (any type or stage) confirmed by official medical records * Has a DSM IV diagnosis of Major Depressive Disorder * Has a HAM-D 24-item score of more than 20 * Failed to receive satisfactory improvement from one prior antidepressant medication at or above the minimal effective dose and duration in the current depressive episode * All participants must have given signed, informed consent prior to registration in study Exclusion Criteria: * Participant had breast cancer with brain metastases * There is evidence of the disease at the time of entry into the trial * Presence or recent history of other concurrent cancers, with the following exceptions: * Participants with completely treated basal or squamous skin cancers can be included in the study if their physicians deem that they are medically stable * Participants with completely treated in situ carcinoma of the breast or cervix may be included in the study if they have not had chemotherapy within the past month and their physicians deem that they are medically stable * Participants with pre-cancerous lesions in the colon can be included in the study if they have not had chemotherapy within the past month and their physicians deem that they are medically stable * Participant had recent surgery (within two weeks) * Participant is undergoing chemotherapy * Participant is pregnant or nursing * Participant has any metallic object in or around their head * Participant has a pacemaker * Has unstable suicidal ideation as determined by the patient's treating psychiatrist * Substance use disorder within the prior six months * Significant history of head injury/trauma as defined by loss of consciousness for more than 1 hour * Recurring seizures resulting from the head injury * Clear cognitive sequelae from the head injury and cognitive rehabilitation following the injury * Any disorder that would predispose the participant to seizures * Use of concomitant medications that substantially increase seizure risk. Such drugs could include neuroleptics (ex. haloperidol, droperidol), clozapine, tricyclic antidepressants (ex. amoxapine, clomipramine), bupropion (particularly the immediate release - IR - formulation) donepezil, psychostimulants (ex. methylphenidate), theophylline and/or other drugs that reduce the seizure threshold. For individuals on any of these medicines, a study clinician will evaluate the drugs and doses to determine the risks and benefits. These will then be discussed with the individual's Primary Care Physician to determine if the individual should be excluded from the study.
