You will be shown inclusion or exclusion criteria for a clinical trial. Given these criteria, your task is to extract all unique entities of the following types: ["Observation", "Condition", "Procedure", "Drug", "Temporal", "Multiplier", "Qualifier", "Negation", "ReferencePoint", "Scope", "Value", "Mood", "Device", "Visit", "Measurement", "Person"].

Please return the output as a JSON object of the format: {"Condition" : ["breast cancer", ...], "Device" : ["ports", ...], "Drug" : ["Atenolol", ...], "Measurement" : ["blood pressure", ...], "Mood" : ["suspected", ...], "Multiplier" : ["more than two", ...], "Negation" : ["no", ...], "Observation" : ["history", ...], "Person" : ["male", ...], "Procedure" : ["surgery", ...], "Qualifier" : ["severe", ...], "ReferencePoint" : ["enrollment", ...], "Scope" : ["infection", ...], "Temporal" : ["one day", ...], "Value" : ["50%", ...], "Visit" : ["ICU", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Patients who may receive therapeutically effective doses via an external beam approach to the lesion of interest as specified by MSKCC Radiation Oncology Department dose constraint criteria. 
Patients with kyphoplasty cement or hardware that would preclude effective catheter placement. 
Patients with paraspinal extension of disease with visceral involvement. 
Abnormal complete blood count. Any of the following: 
Platelet count < 75,000/ml 
Hb level < 9gm/dl 
WBC < 3.5/ml 
Abnormal coagulation profile: INR > 2.5 and/or PTT > 80 
Patients who are on anticoagulation medication that may not be safely held for the procedure (≥ 5 days for antiplatelet agents and warfarin; ≥ 24 hours for low-molecular weight heparin formulations) will be excluded. 
Contraindications to general anesthesia
