20091112 Grade-Breast: How is this field coded for a breast tumor described as "intermediate nuclear grade"? See Discussion.

Guidelines for selecting grade for breast primaries prioritize nuclear grade right after B&R grade. The conversion table displays only numeric values for nuclear grade. How is grade coded for tumors in which nuclear grade is described by terminology? Does it make a difference if the tumor is invasive or in situ?

Example 1: Ductal carcinoma, intermediate nuclear grade.

Example 2: Ductal carcinoma, high nuclear grade.

Example 3: Ductal carcinoma, moderate nuclear grade.

Example 4: DCIS, intermediate nuclear grade.

Use the table on page C-607 of the 2007 SEER manual. The terms "low," "intermediate," and "high" appear in the column labeled "BR Grade." Use this column to determine the appropriate grade code when grade is described using these terms. If the grade of an in situ tumor is described using these terms, use the table to determine the appropriate code for the grade field.
20140009 Primary site: What primary site do I assign to a Squamous Cell Carcinoma of the parapharyngeal space when there is no other info available regarding a more definitive site within the parapharyngeal space? Each physician involved with the case states the primary site is the parapharyngeal space. This is a patient who was diagosed and treated elswhere and was seen at our hospital several months later for a radical neck dissection for suspected lymph node mets. We recommend C490 for a primary originating in the parapharyngeal space. This space contains part of the parotid gland, adipose tissue, lymph nodes, nerves, arteries and veins.
20100061 MP/H Rules/Histology: The 2010 SEER Manual has omitted some useful information in the Histologic Type ICD-O-3 section, specifically the statement of "Do not revise or update the histology code based on subsequent recurrence(s)". Will this statement be added to the revisions of the MPH rules? See Discussion. Example: A 2005 diagnosis of left breast lobular carcinoma [8520/3], followed by a 2009 diagnosis of left breast ductal carcinoma [8500/3]. Rule M10 states this is a single primary, but there is no information in the Histology rules (Multiple Tumors Abstracted as a Single Primary) that the original histology should be retained, thus a person could potentially use these rules to change the original histology to 8522/3 [duct and lobular carcinoma] per rule H28. We will reinstate the instruction not to change the histology code based on recurrence in future versions of the histology coding instructions. However, this instruction may not be applicable to all anatomic sites. It will be reinstated on a site-by-site basis. You may also refer to the instructions on Page 7 of the 2010 SEER Manual under the heading "Changing Information on the Abstract."
20041018 Grade, Differentiation: Can grade be assigned based on a thin prep if there is no grade in the other pathology reports? See Discussion.

Example:

Vag & Cervical Thin-Prep: Adenocarcinoma, endometrial, high grade.

Resected Uterus and Left Adnexa: Endometrial papillary serous carcinoma arising in an endometrial polyp.

When it is the only source specifying the grade, code grade from the thin prep.
20051062 Surgery of Primary Site--Prostate: How is the use of a Laserscope Niagara laser (modulated KTP-YAG laser beam (Niagara 122 prostate vaporization)) coded for prostate primaries? See Discussion. The Laserscope Niagara laser performs an operation similar to the TURP, but there is virtually no bleeding and patients can sometimes go home the same day, most without a catheter. The laser is delivered through a fiber (the thickness of hair) into the cavity via an endoscope inserted through the urethra. When performed as part of the first course of therapy, assign surgery code 15 [Laser ablation] to Niagara laser photovaporization of the prostate.
20041099 First Course Treatment: If a patient makes a blanket refusal of all recommended therapy or refuses all treatment before any therapy was recommended, are only immunotherapy and hematologic/endocrine therapies to be coded as refused (code 87)? Or should all treatment modalities be coded as refused if a patient makes a blanket refusal? Or should none of the treatment modalities be coded as refused because we do not know what would have been recommended? See Discussion. Coding instructions for immunotherapy and for hematologic/endocrine procedures state that Code 87 is to be assigned if either of the following circumstances apply: 1) If the patient made a blanket refusal of all recommended treatment. 2) If the patient refused all treatment before any was recommended. These instructions are not included for other treatment modalities. When the patient refuses treatment, the first course of therapy is no treatment. Code all treatments as refused.
20061111 Reportability/Behavior--Skin: Is an "atypical fibroxanthoma (superficial malignant fibrous histiocytoma)" with an ICDO-3 histology code of 8830 considered reportable with a behavior code of 3 or is it nonreportable with a behavior code of 1? Yes, "atypical fibroxanthoma (superficial malignant fibrous histiocytoma)" is reportable. The information in parentheses provides more detail and confirms a reportable malignancy.
20051059 Behavior/Date of Diagnosis--Lung: If the term "Pancoast tumor, NOS" is considered malignant by definition, should the date of diagnosis be coded to the date of the clinical diagnosis when the clinical diagnosis is made prior to the histologic confirmation of the malignancy? Yes, Pancoast tumor is by definition malignant. It is defined as a lung cancer in the uppermost segment of the lung that directly invades into the brachial plexus (nerve bundles) of the neck, causing pain. If a Pancoast tumor was identified on imaging prior to the biopsy, the date of diagnosis should be linked to the Pancoast tumor report.
20140011 MP/H Rules/Multiple primaries--Breast: Is the diagnosis of Paget disease two years after a diagnosis of infiltrating duct carcinoma of the same breast a new primary? See discussion. A patient was diagnosed and treated in 2010 for infiltrating duct carcinoma of the left breast. There was no mention of Paget disease. Then in 2012, the same patient was diagnosed with Paget disease of the nipple of the left breast. Rule M9 seems to apply; so this is the same primary, correct? And the information about the Paget disease is simply never captured, correct? Yes, Rule M9 makes this a single primary. You could revise the original histology code to 8541/3 on the assumption that Paget was present at the original diagnosis, but not yet identified.
20051078 Surgery of Primary Site--Melanoma: If the surgical margins are greater than 1 cm for length and width but less than 1 cm for depth, do we code surgery in the 30-33 range? Yes, assign a surgery code from the 30-33 range when any margin is less than 1 cm. Since tumor thickness is an important prognostic factor for cutaneous melanoma, the deep margin is of particular importance.
