Observable Entity Defining Attributes Employed in this Project

The Cancer Synoptic Reporting Project Group operated under the data modeling paradigm that the |Observable entity (observable entity)| concept provides the context to correctly and unambiguously interpret the observation. Therefore, understanding the observable entity concept model is fundamental to use of the cancer synoptic content. Authored content for observable entities of this project are found <<1145211006 |Proliferative mass observable (observable entity)|

The table below provides an overview of the defining attributes used to author cancer synoptic reporting concepts, including a description of the target values for these attributes.

• << ;

| This attribute is used to assert the entity that carries the property being measured. In most cases, the target values are << | The inherent location attribute is used to describe the anatomical location of the entity that carries the property being assessed. In most cases, the inherent location indicates the anatomical location of the primary malignant neoplasm, that is the primary organ affected by the malignancy. | This attribute is used to indicate an entity that is being assessed for presence such as necrosis within a neoplasm. It is also used to represent the numerator in a percent observation. | This attributed is used for the denominator in a percent or number fraction observable. | Direct site is specifically used to define the specimen in which the observation is being made. | Technique is used to define the method by which the observation is being made. This attribute is used to specific methods of tumor staging, histologic grading methods, direct vision (gross) evaluation, microscopy and immunohistochemistry methods. | The time aspect for all cancer pathology observable entities is

| This attribute is used to describe the evaluation scale used for the observation.

• • is used to describe observable entities assessing morphologies, body structures, and procedures.

• • is used in histologic grade observations and observations indicating the presence, absence or degree of presence.

| Characterizes is used to represent the underlying processes of the neoplasm. These include << and | This attribute is used to define the "end point" of the process indicated by the characterized attribute/value pair. In most concepts, this associated value of this attribute is << to indicate where the neoplasm has grown or metastasized.
