Report Question ID Question Discussion Answer Cancer Site Category Data Item Category Year
20071025 Radiation Therapy: How is radiation coded when it is "recommended" but the patient dies before radiation is started? See Discussion. Code 0 seems appropriate but then we would lose the fact that it had been recommended. All of the other modalities give an option for 'recommended but patient died prior to treatment.' Is there a reason this option is not given for radiation?

Code Radiation (Rx Summ--Radiation) to 0 [None; diagnosed at autopsy].

SEER does not collect the Reason For No Radiation field. However, those who abstract using software that captures this data item can identify these cases. Code 5 [radiation not administered because patient died] reflects this situation.

Radiation (Rx Summ-Radiation) is a SEER field. This field is derived from the data collected in Rad-Boost Rx Modality and Rad-Regional TX Modality. These fields do not include a choice for "radiation not given because the patient died prior to treatment." Therefore, this information cannot be coded in the Radiation field.

20081032 Radiation Therapy--Breast: If hospital records indicate that a mammocyte intracavitary radiation therapy device was placed in the breast, but there is no follow-up documentation of radiation actually being given, should we code radiation 2 (implants) or 8 (recommended, unknown if given)? Assign code 8 [recommended, unknown if administered]. Check this case periodically, and others coded 8. Update if further information becomes available. Breast Radiation Therapy 2008

Radiation Therapy--Breast: Are iodine 125 (I-125) seed implants for breast cancer coded as brachytherapy or as a localization technique similar to wire localization? See Discussion.

We are seeing many I-125 seed implants for breast cancer. Many of my associates are coding them as brachytherapy. I think they are the newest of the localization technique like wire localization but with greater accuracy. Most are done the same day as the surgery so brachytherapy does not make sense. Which is correct?

I-125 seeds could be used for brachytherapy for breast cancer or as a localization technique for nonpalpable breast tumors. If the seeds were in place a short time and removed as part of a breast surgical procedure, they were likely used for tumor localization. Radioactive seed localization (RSL) is thought to be more precise than the wire implantation technique for localizing lesions.

Radiation: Is "consolidated" radiation therapy coded as part of first course therapy when there is no documentation of "planned treatment" and the radiation is done 4 months after the initiation of treatment?

Yes, "consolidation" treatment is part of a planned treatment regimen. A treatment regimen may consist of the four following phases:

1. Induction (remission induction)

2. CNS preventive therapy

3. Consolidation/intensification

4. Maintenance

Radiation Therapy: Is I 131 sodium iodide coded as radiation? SINQ 20031040 says to code Radiation as 3 (radioisotope) but SEER*Rx says not to code it.

Code sodium iodine (I 131) therapy in Radiation Treatment Modality as code 13 (Radioisotopes, NOS). Code Radiation External Beam Planning Technique as code 88 (not applicable). Do not code if used in diagnostic procedures.

Radioactive I 131 should be coded when given in therapeutic doses (usually 30-50mCi but could be higher in high risk patients). The same agent is used for diagnostic imaging, but the dose is very small (1-3mCi).

We will update SEER*Rx.

20010118 All Surgical Fields/Radiation Sequence with Surgery--Unknown Primaries: What codes are used to represent these fields for an unknown primary treated with a radical neck dissection followed by radiation therapy?

For unknown primaries treated with a lymph node dissection and diagnosed 1/1/2003 and after, code:

1) Surgery to Primary Site: 98 [All unknown and ill-defined disease sites, WITH or WITHOUT surgical treatment].

2) Scope of Regional Lymph Node Surgery: 9 [Unknown or not applicable].

3) Surgical Procedure of Other Site: 1 [Surgery to other site(s) or node(s), NOS; unknown if regional or distant].

4) Radiation Sequence with Surgery: 3 [Radiation after surgery]. Any planned surgical treatment is used to code radiation/surgery sequence (per CoC I&R).

20031017 Reason for No Surgery of Primary Site: Does code 2 [Contraindicated due to other conditions; autopsy only case] or code 1 [ Cancer-directed surgery not recommended] have priority when coding this field for extensive tumors not surgically treated because of existing comorbidities? See discussion.

Example:

Patient has Stage IVA carcinoma of the tongue. The physician states that patient is not felt to be a good surgical candidate secondary to multiple medical frailties. Patient is treated with beam radiation.

In this case, how do we code Reason for No Site Specific Surgery? Do we use code 2 because surgery was contraindicated due to co-existing medical conditions or do we use code 1 because the tumor is very extensive and surgery would probably not be done anyway?

SEER has not established a priority for assigning the Reason for No Surgery of Primary Site codes. Assign the code which best describes the reason surgery was not performed.

Example: Assign code 2, Contraindicated due to patient risk factors. According to the physician, this is the reason that surgery was not performed.

 N/A Reason no treatment 2003
20031147 Reason No Cancer-Directed Surgery--Hematopoietic, NOS: Is this field always coded to 1 [not performed, not part of first course] for leukemias & other hematopoietic diseases? For cases diagnosed 2003 and later: For sites where "Surgery of the primary site" is coded 00 or 98 (hematopoietic included), Reason for No Surgery of Primary Site should be coded as 1 [Surgery of the primary site not performed because it was not part of the planned first course of treatment]. On rare occasions, there may be surgery to the primary site for a hematopoietic disease, such as an excisional biopsy of a myeloid sarcoma. Refer to the "Abstracting and Coding Guide for the Hematopoietic Diseases" for cell-type-specific treatment information. N/A Reason no treatment 2003
20021208 Reason for No Cancer-Directed Surgery: Could you explain why this field would be coded to 1 [Cancer-directed surgery was not recommended] or 2 [Contraindicated due to other conditions] for a case that presents with distant metastasis at diagnosis?

For cases diagnosed 1998-2002:

Code the Reason for No Cancer-Directed Surgery field to 1 [Cancer-directed surgery was not recommended] for patients who present with either a primary site or histology for which surgery is not a standard treatment. Also use code 1 for those patients who present with distant disease for a primary site that is typically treated surgically. Patients with distant metastasis typically do not have surgery performed as part of first course of treatment.

Code 2 [Contraindicated due to other conditions] is used when surgery would normally be recommended for the site (given the current stage of the tumor) but other medical conditions pose too much of a risk for the patient to undergo surgery.

20071030 Reporting Source: If the only patient record available for a physician office biopsy is the pathology report identified from a freestanding laboratory, is reporting source coded to 3 [Laboratory Only (hospital-affiliated or independent)] or 4 [Physicians office/Private Medical Practitioner (LMD)]? See Discussion. A case was identified through a pathology report from a freestanding lab. The doctor who submitted the specimen left the state. His records cannot be located. Because the patient had the specimen removed at a physician's office, not at a path lab, is Type of Reporting Source field coded to the physicians office?

Reporting Source is the source that provided the best information used to abstract the case.

For this case, assign code 3 [Laboratory Only (hospital-affiliated or independent)]. Reporting source should reflect the lab where this case was identified. The MD office added nothing to the case, not even a confirmation of malignancy.
