EOD-Size of Primary Tumor--Breast: For breast cancer cases, is code 002 [Mammography/xerography diagnosis only with no size given (tumor not clinically palpable)] to be used only when there is no work-up beyond a clinical one? See discussion.
Usually when a mammogram has a malignant diagnosis, the tumor is clinically palpable, but occasionally the tumor is not palpable.
For example, on the mammogram, lesions are identified in the breast. PE--the breasts are palpably normal. Breast biopsies--two ductal carcinomas, no statement of size. Mastectomy--no residual. Should the size be coded to 999 rather than 002?
For cases diagnosed 1998-2003:
In the case you provided, code the EOD-Size of Primary Tumor field to 002 [Mammography/xerography diagnosis only with no size given (tumor not clinically palpable)]. A known code in the size field should always take precedence over 999 [Not stated]. Code size from the records in priority order as stated in EOD, from pathology, op report, PE, mammogram, etc. (See EOD for complete instructions.)
Code size as 999 only when there is a clinically palpable lesion with no size stated in the path, PE, or mammogram.
If there is a lesion seen on mammogram that is not clinically palpable, a stated size taken from the path or mammogram would take precedence over code 002; however, if there is no stated size, use code 002 rather than 999.
EOD-Size of Primary Tumor--Breast: How do we code this field when there is a difference between the size of the tumor mentioned in the gross (i.e., macroscopic description) and the comment sections of a pathology report? See Description.
Path Macro Summary states size as 1.5 cm. The path comment states "largest area of tumor seen is 1.5 cm. However, 8 of the nearly contiguous sections are involved with an estimated 2.4 cm area of involvement."
For cases diagnosed 1998-2003: Code the size of the largest area of tumor from the path macro summary. For the example provided, code the size as 015 [1.5 cm]. In this case, the additional sections of tumor described in the path comment do not seem to represent pieces of one larger tumor. The 2.4 cm estimated area of involvement was determined by adding together noncontiguous tumor sections. According to the CAP protocol for breast, Note J "When 2 or more distinct invasive tumors are present, each is separately measured...they are not combined into a single larger size."
EOD-Size of Primary Tumor--Breast: How would this field be coded, using the revised and expanded breast code, for a lesion described as "1.3 cm infiltrating ductal carcinoma, associated DCIS?"
For cases diagnosed 1998-2003: Code size of primary tumor as 013. The phrasing suggests that the infiltrating ductal carcinoma measures 1.3 cm. DCIS is also present, but no size mentioned.
EOD-Size of Primary Tumor--Breast: If the patient has inflammatory carcinoma of the breast, is the tumor size coded as 998 even though we have a tumor size?
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary tumor field to 998 [Diffuse; widespread; 3/4 or more of breast; inflammatory carcinoma] for all inflammatory breast carcinomas.
These cases have a worse prognosis because of the dermal lymphatic invasion. Half of the inflammatory breast carcinomas will have no palpable mass.
EOD-Size of Primary Tumor--Breast: The path report provides a size for both the Paget disease and the underlying intraductal component in the breast. Should we assume the Paget disease to be invasive and code the size of the primary tumor to that invasive component? See discussion.
For example, path diagnosis for resection gave the size of the Paget disease as 1 mm and the size of the underlying intraductal tumor as 4 cm. Should size for this breast case be coded to 040 or 003, less than 3 mm.
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary Tumor field to 040 [4 cm], the size of the larger underlying intraductal tumor. Paget disease is classified according to the size of the underlying in situ or invasive tumor. Paget with an underlying in situ tumor is staged as in situ to match the AJCC classification of this disease process.
EOD-Size of Primary Tumor--Breast: When the pathology report does not specify dimensions for the invasive component, how is tumor size coded? See discussion.
In some cases the tumor has both invasive and in situ components. The pathologist sometimes does not report the size for the invasive portion of the tumor. In most cases, the invasive portion is described as a percentage of the tumor mass.
From January 1, 1998 and forward: Follow the Revised Breast EOD instructions. If the size of the invasive component is not given, record the size of the entire tumor in the EOD-Size of Primary Tumor field. Assign the appropriate EOD-Extension code for the situation.
EOD-Size of Primary Tumor--Cervix: When both a depth and diameter of the tumor are provided and the description of the diameter is provided in a range, how do you code the size of the primary tumor? See discussion.
Path states "microscopic focus of endocervical glands considered invasive adenoca...maximum depth of that focus measures approximately 2 mm. Maximum diameter of that focus measures 3-4 mm."
What size would be coded for this case: 999, 002, 003, or 004?
Code the EOD-Size of Primary Tumor field to 004 [4 mm]. Code the diameter dimension in the EOD-Size of Primary Tumor field and the depth dimension iin the EOD-Extension field. Code the largest number associated if a range is provided for the diameter of the invasive tumor.
If the size of the diameter had not been mentioned, the EOD-Size of Primary Tumor field would have been coded to 001 [microscopic focus or foci only], which ignores the size associated with the depth dimension of the tumor.
EOD-Size of Primary Tumor--Colon: When an adenocarcinoma is stated to be arising in an adenoma and the "tumor size" stated in the final pathologic diagnosis is the same size as the mass described in the gross description, should we assume that the entire polyp has been totally/near totally replaced by tumor and code the tumor size stated in the final path diagnosis?
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary Tumor field as stated by the pathologist in the final pathologic diagnosis. If the size of the tumor is the same as the size of the polyp, assume the polyp was completely replaced by tumor.
EOD-Size of Primary Tumor--Corpus Uteri: If both the width and depth of the tumor are provided, do we code the largest dimension in the tumor size field? If the width dimension is not provided, can we code the depth of the tumor in the tumor size field? See discussion.
Example: An endometrial primary is described as having, "a soft lobulated tumor diffusely involving the entire endometrium, extending 2.0 cm into the myometrium."
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary Tumor field to 999 [unknown] for this case because this field is supposed to reflect the dimension for tumor width and not tumor depth. Tumor depth is coded in the EOD-Extension field.
EOD-Size of Primary Tumor--Lung: Can tumor size of 002 [Malignant cells present in bronchopulmonary secretions] be used when there is a lung mass seen but the diagnosis is from a positive bronchopulmonary secretion?
For cases diagnosed 1998-2003:
EOD-Size of Primary Tumor code 002 [Malignant cells present in bronchopulmonary secretions] is used only when there is no visible primary lung tumor and bronchopulmonary secretions are positive for lung malignancy.
Even if the diagnosis was made by cytology of broncho-pulmonary secretions, if there is a visible mass, code the size of the mass if known, code 999 if size is unknown.
