• The code identifies the observation or test, not the actual result.

Key facts

• Hospital admission.first contact [Date and time] Cancer
• Hospital admission.first contact
• Date of first patient contact, as inpatient or outpatient, with the reporting facility for the diagnosis and/or treatment of the tumor. The date may represent the date of an outpatient visit for a biopsy, x-ray, scan, or laboratory test. See page 81 for date format. When Pathology Specimen Only (Class of Case 7, Type of Reporting Source 3) tumors are collected, the Path--Date of Specimen Collection [7320] from the pathology report should be used for the Date of 1st Contact. If a pathology-specimen-only case is followed by a patient contact with the facility for the diagnosis and/or treatment of the respective tumor, the Date of 1st Contact is not changed. The date of the initial pathology laboratory specimen collection remains the Date of 1st Contact. When Death Certificate Only (Class of Case 8, Type of Reporting Source 7) tumors are collected, the date of death should be used as the Date of 1st Contact. When Autopsy Only (Class of Case 5, Type of Reporting Source 6) tumors are collected, the date of death should be used as the Date of 1st Contact. Timeliness of abstracting (and reporting) is a concern for all standard-setting organizations. Date of 1st Contact is one of several data items that can be used to measure timeliness of reporting by individual facilities to central cancer registries. For tumors that are not diagnosed at the reporting facility (Class of Case 2, 3, or 4), the Date of 1st Contact [580] can be used in conjunction with the Date Case Report Received [2111] to measure timeliness of reporting by individual facilities. To accurately measure the timeliness of data collection and submission of abstracts that are first diagnosed at autopsy (Class of Case 5, Type of Reporting Source 6) the date of death should be used as the Date of 1st Contact since the diagnosis was not determined until the autopsy was performed. Death Certificate Only cases (Class of Case 8, Type of Reporting Source 7) are created only by the central registry. For these cases, Date of 1st Contact should be filled with the date of death, and timeliness for DCO cases should be measured by different criteria...
