20000535 EOD-Pathologic Extension--Prostate: Is extracapsular extension implied by the following phrases: "case staged as C" and "case staged as T3a"? See discussion.

Example: A prostatectomy was done on 6/29. The physician staged the case as a "C" on 7/2 and as T3a on 8/6. It appears the physician is interpreting the following pathology information as unilateral extracapsular extension: "The tumor on the right extends to the inked surface of the gland. In this area the capsule appears absent." Should pathologic extension be coded to unilateral extracapsular extension [42]?

For cases diagnosed 1998-2003:

Yes. Use the best information available to stage this case. In this case, the best information is the physician's statement that the case is stage T3a. Without any additional information, the EOD-Extension field is coded to 42 [Unilateral extracapsular extension (pT3a)] on the basis of the T3a stage by the MD. When there is a conflict between different staging systems, default to the AJCC stage.

20000485 EOD-Extension--Lung: Should the phrase "some pleural fluid in both posterior gutters" be interpreted as pleural effusion for lung primaries? See discussion. CT scan: "3 cm mass left upper lobe of lung. Some pleural fluid in both posterior gutters. Large matted hilar lymph nodes, left. Some narrowing left upper bronchus by this adenopathy. Squamous cell ca lung with mets to left hilar lymph nodes, most likely possibility." Would you code extension to 72 [malignant pleural effusion; pleural effusion, NOS]?

For cases diagnosed 1998-2003:

Yes. Code the EOD-Extension field to 72 [malignant pleural effusion, pleural effusion, NOS]. Pleural effusion is mentioned as being present.

20021060 EOD-Size of Primary Tumor: The EOD Manual instructs us not to code the size of a cyst. Can we code the size of tumor lesions described as being multicystic, multiloculated, or as a complex mass with cystic areas? See discussion.

Example 1: Large multicystic ovarian mass lesion measuring 10 cm. Sections through the specimen show a multicystic and solid mass with abundant fluid exuding from the cut surfaces (Size of the solid portions is not stated).

Example 2: A brain MRI: 9-cm. complex mass with cystic areas.

For cases diagnosed 1998-2003:

Yes, if the cystic mass is pathologically confirmed to be malignant, code the EOD-Size of Primary Tumor field based on the size of the mass in the absence of a more precise tumor size description. For the examples in the discussion section, code the EOD-Size of Primary Tumor field to: 1) 100 [10 cm]. 2) 090 [9 cm].

As a point of interest, the size of tumor for ovarian and brain primaries is not used in either analysis or as a prognostic indicator for survival. Therefore, spending time separating the cystic and solid portions of the tumor is unnecessary.

20000428 EOD-Clinical Extension--Prostate: How do you distinguish between clinical extension codes of 10, 13, 14, and 20 for cases with a benign prostate per digital rectal exam that appear localized after TURP/prostatectomy? Can the clinical extension code of 10 be used if the term "microscopic carcinoma" is noted in the pathology report without also mentioning "foci" or "Stage A" for clinically inapparent tumors?

For cases diagnosed 1998-2003:

When the prostate feels benign and the cancer is found incidentally at the time of the microscopic exam, code the EOD-Extension field to 10 [number of foci or % of involved tissue not specified]. Code as 13 (less than or equal to 5%) or 14 (greater than 5%) if percentage involved is given in the tissue resected. If the path report states "solitary focus of carcinoma" without mentioning the total amount of tissue resected, code extension to 13. If there is more than one focus, code extension to 10. Don't assign a code of 20 unless the tumor is clinically apparent.

20021005 EOD-Extension--Lymphoma: What code is used to represent this field for an extranodal lymphoma that has more than one tumor in the primary site OR has intraluminal extension from the primary site to an adjacent organ? See discussion.

1. Small lymphocytic lymphoma with 2 tumors in the stomach.

2. Lymphoma involving the cecum and ileum.

3. Lymphoma of the fundus of stomach with extension into the esophagus.

For cases diagnosed 1998-2003:

Using the EOD scheme for lymphoma, code the Extension field to 11 [Localized involvement of a single extralymphatic organ or site; Stage IE] for all 3 of these cases.

For the stomach lymphoma: There are 2 areas of lymphoma, but it is still confined to one site.

For the other 2 lymphomas: Intraluminal (mucosal) spread of the lymphoma never equals extension. The same phrase that was added to code 21, "Direct extension to adjacent organs or tissues", will be added to code 11 in the Collaborative Stage System. Neither "mucosal spread to a contiguous organ" or "direct extension into a nearby organ" affect staging. Both are still coded to 11 as long as there are no other sites of lymphoma involvement.

EOD code 80 is poorly written. It does not mean diffuse invovement or multiple tumors in a single organ but rather "diffuse disease in two or more organs."

20031148 EOD-Systemic Symptoms at Diagnosis--Lymphoma: Would the description, "three days of typical cold symptoms including congestion, sneezing, chills and advanced difficulty breathing and some fever" qualify as B-Symptoms?

For cases diagnosed 1998-2003:

Use the following criteria to determine whether or not certain clinical findings qualify as "B" symptoms.

1. Fevers. Unexplained fever with temperature above 38 degrees C.

2. Night sweats. Drenching sweats that require change of bedclothes.

3. Weight loss. Unexplained weight loss of more than 10% of the usual body weight in the 6 months prior to diagnosis.

Pruritus alone does not qualify for B classification, nor does alcohol intolerance, fatigue, or a short, febrile illness associated with suspected infections.

The clinical description in the example above does not meet the criteria for B symptoms. Generally, the symptoms in the B category have to occur over an extended period of 7 to 30 days. In this case the fever is explained by "typical cold symptoms" and in addition, three days of fever is not a long enough period.

20000532 EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined: Should a lymph node biopsy be counted in these fields or are these fields for lymph node dissections only? See discussion. Example: 1) Lymph node biopsy: adenocarcinoma. 2) Lymph node dissection: 4/15 regional lymph nodes positive for adenocarcinoma.

For cases diagnosed 1998-2003:

These fields record the number of regional lymph nodes examined pathologically whether from a biopsy or from a dissection. If the single lymph node biopsied was a regional lymph node, code the Number of Regional Lymph Nodes Positive field to 05 and the Number of Regional Lymph Nodes Examined field to 16. If the lymph node biopsied was a distant node, code these fields to 04 and 15 respectively.

20020003 EOD-Size of Primary Tumor: Can you code the tumor size if you have the aggregate size given for two or more tumor masses?

For cases diagnosed 1998-2003:

No. Never code the aggregate size in the Size of Primary Tumor field when the pieces removed come from TWO OR MORE tumors. If there is a clinical statement regarding the size of two or more tumors, code this field to the size of the largest tumor.

The aggregate size can only be used to code the Size of Primary Tumor field when the PATHOLOGIST estimates the size of the tumor from the pieces of ONE tumor removed by the surgeon.

20010104 Date of Diagnosis--Lung: Based on Note 7 in the lung EOD, should the Date of Diagnosis field be coded to an earlier CT scan date with a reported diagnosis of "RUL mass with mediastinal lymphadenopathy" or to the later biopsy date with a reported diagnosis of small cell carcinoma? See discussion. Note 7 states that "mediastinal lymphadenopathy" indicates involved lymph nodes for lung primaries. Should the date of diagnosis be back-dated to the date of the scan?

For cases diagnosed 1998-2003:

No, code the Date of Diagnosis field to the later biopsy date. Note 7 is intended for use in coding the EOD-Extension field, not the Date of Diagnosis field. The earlier scan has a diagnosis of RUL "mass" not a "malignancy" so the fact that there is mediastinal lymphadenopathy mentioned in that scan is not used to help determine date of diagnosis.

20000553 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.
