Patient has a history of AIN I/low-grade squamous intraepithelial lesion (LSIL) dating back to at least 2015, was diagnosed with AIN II-III in 12/2019, and then diagnosed again with AIN II-III in 08/2021. There is no indication of treatment or a disease-free interval for this patient.

SINQ 20210015, while not an exact match to this case, implies there is no clear disease-free interval for these AIN diagnoses, so it is the same non-reportable neoplasm diagnosed prior to reportability (12/2019). However, there was a diagnosis of a reportable neoplasm in 2021, so it also seems possible this would be accessioned as a reportable tumor based on a diagnosis of reportable tumor diagnosis in 2021.

With the reportability changes for these intraepithelial neoplasia II/II-III tumors, these situations will arise more frequently.

Patient was diagnosed on biopsy with lentigo maligna melanoma of the nasal dorsum. The only available documentation of the subsequent surgery is a single pathology report with the nasal dorsum “staged excision (debulking specimen)” and four additional “staged excision” specimens of the same site.

Is it safe to assume this is a Mohs surgery? Would it be safe to assume staged excisions of sites other than skin of face, are also Mohs surgery?

Lymphoma case diagnosed in 2021: The patient had first round of systemic therapy as documented in the treatment plan and a post-chemotherapy PET scan that showed residual disease. The patient then had a different combination of systemic therapy and still had some residual disease. The patient was given a third round of different combination of systemic therapy in preparation for stem cell transplant. According to the physician post-stem cell transplant note, the patient achieved complete remission.

Is the first course of therapy the first round of systemic therapy only or is it all the therapy given to achieve remission?  It seems like only the first round of systemic therapy is first course of therapy for both leukemia and lymphoma in the hematopoietic manual. I thought all treatment for all hematopoietic cases was first course until remission achieved or progression was evident.

History provided by the oncologist

Right neck mass since 2019; 04/07/20, initial biopsy p16-negative SCC, delay of treatment due to patient preference, agreed to biopsy of tonsil and work-up August 2022; right tonsil biopsy: p16-positive, G2 SCC, nodal mass at that time >6 cm with extensive extranodal extension, Stage III (cT2, cN3, cM0, p16-positive); based on this history, was staged as a tonsil primary and p16-positive.

Patient details

1. March 2020, CT neck and chest revealed a 0.5 x 2.7 x 2.3 cm low-density necrotic nodal mass at right neck level 2 suspicious for metastatic disease.  There was a slight asymmetric increased size of the right palatine tonsil.  There are a few sub-4 mm pulmonary nodules which are nonspecific.

2.  April 7, 2020, FNA of right neck mass with pathology revealed p16-negative SCC   

3.  April 20, 2020, PET/CT revealed 3 x 2 cm right-sided level 2 node with FDG avidity  

4.  May 5, 2020, flexible laryngoscopy showed no obvious primary lesion   

5.  May 2020, after evaluation by a medical oncology, patient declined any treatment  

6.  June 17, 2022, return visit in medical oncology after PET/CT demonstrates significant progression in the neck; patient definitively declines chemo, but would like surgical opinion.  Now has more rapidly progressive disease with skin breakdown and weeping from malignant lesion right neck.  

7.  June 22, 2022, radiation oncology consultation   

8.  July 15, 2022, tonsil biopsy: Invasive squamous cell carcinoma, moderately differentiated with LVI, p16-positive  

9.  Patient now agreeing to treatment with radiation: Tooth extractions 8/30/2022, radiation planning 9/14/2022  

10.  Patient consulted with cancer specialist who explained surgery is not recommended given level of extranodal extension and risk of seventh cranial nerve paralysis and fistula formation with surgical excision and who recommended chemoradiation

11.  September 9, 2022, patient presented for radiation CT simulation/treatment planning and informs treatment team. Patient declined/refuses concurrent chemotherapy despite recommendations from two cancer institutions.

Examples:

Bladder TURB:  Invasive high grade urothelial carcinoma with poorly differentiated (40%), lipoid (5%), and sarcomatoid (55%) components.

Bladder tumor base TURB:  Invasive high grade urothelial carcinoma with poorly differentiated (65%) and sarcomatoid (30%) components.

The Urinary Sites Solid Tumor Rules, histology coding rules, say to code the most specific histology or subtype/variant, regardless of whether it is described as majority, minority, or component.  Poorly differentiated (8020) and sarcomatoid (8122) are both urothelial subtypes, but there is no rule to instruct how to code a tumor/tumors with multiple urothelial subtypes.

In the September 2021 Urinary Sites Solid Tumor Rules update, the term configuration was removed from the “DO NOT CODE histology when described as” list. However, it was not added as a term that can be used to code the more specific histology for urinary tumors.

Can configuration be used to code the more specific histology 8130 (papillary urothelial carcinoma) when the diagnosis is urothelial carcinoma, tumor configuration: papillary?

Laterality is often not noted for these sella turcica meningiomas; therefore, Laterality is often coded as 9 (Unknown). Because the sella turcica appears to be a midline structure in the base of the skull, is Laterality code 5 (midline) more appropriate when additional information is unavailable?

For example:

-ultrasound of the right eye: consistent with a nevoma/melanoma; we could not find any indication that nevoma is a reportable term

-bladder biopsy pathology report:  severe urothelial dysplasia/carcinoma in situ (CIS)

As a central registry, we receive some limited information cases like this where there is no record of treatment or possibility to follow-back to physicians for clarification, so we want to make sure we are reporting them correctly.
