IMC-A12 (Cixutumumab) is listed as a BRM agent in SEER*Rx, but the Remarks section indicates it should be coded as Other Therapy until there is FDA approval. It is unclear if FDA approval was ever given for this agent. We are mainly seeing it given for prostate primaries.

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.

In the WHO Classification of Female Genital Tumors, 5th edition, for the uterine cervix squamous intraepithelial lesions, there is related terminology for high grade squamous intraepithelial lesion HSIL (CIN3) 8077/2 and it is severe squamous dysplasia; squamous cell in situ. However, in the online WHO Classification of Digestive System Tumors, 5th edition, there is no related terminology for esophageal high-grade squamous dysplasia, 8077/2. Can you collect cases of severe dysplasia the same as cases of high grade dysplasia? 

Patient had a partial nephrectomy with final diagnosis of papillary renal neoplasm with reverse polarity.  Diagnosis comment states: Papillary renal neoplasm with reverse polarity is currently considered to be a histologic variant of papillary renal cell carcinoma; however, recent studies suggest that it has a very indolent clinical behavior.

Patient has a remote history of a right thalamic mass status-post two resections; reported as malignant oligodendroglioma (pathology not received) and chemo/radiation therapy, who recently presented with persistent headaches. Imaging revealed a 3.4 cm heterogeneous lobulated right thalamic mass with coarse calcifications and a probable cystic component.

Pathologist indicates the histologic and immunophenotypic features of this neoplasm are that of relatively circumscribed neuroepithelial tumor without high grade features (mitotic activity, microvascular proliferation, necrosis). Molecularly this neoplasm is characterized by a PATZ1-EWSR1 fusion, which has recently been proposed to be a distinct neuroepithelial tumor entity with a broad histological spectrum.

A January 2022 endometrium biopsy and curettage both show final diagnosis of “mild cytologic atypia and glandular crowding, at most endometrioid intraepithelial neoplasia.”  Any subsequent surgery path is unlikely to provide clarification.

Patient has a diagnosis of myeloid sarcoma presenting as multiple erythematous papules and nodules on back, chest, right arm & shoulder. Oncologist did not mention any evidence or suspicion of an associated AML diagnosis.

HemeRetic schema EOD Primary Tumor Note 1 states that myeloid sarcoma can be coded as localized (code 100) or systemic (code 700). It is not clear what would qualify as systemic disease for myeloid sarcoma.

A 17 year old exchange student was brought into the hospital with appendicitis.  The patient had an appendectomy; there was no follow up treatment.  5/27/2006 pathology report of vermiform appendix:  Adenocarcinoid appendix <5 mm tumor limited to appendix.

The patient has no record in Lexis Nexus and no social security number.  The address is a post office box; additionally, the patient’s birthplace is Switzerland and is lost to follow up.
