Testing Algorithm
Based on the selection for the "Current Cancer Diagnosis" question present on the order placed by the clinic, the in-house IHC Biomarker testing below will be performed (column 2) in addition to molecular testing performed at Tempus. Molecular orders initiated by "advanced" reflex tasks in pathology also initiate in-house IHC Biomarker/prognostic testing (column 3) that will be performed prior to sending out to Tempus for molecular testing.
| Cancer | IHC Biomarker perf by UVMMC when Tempus ordered by clinical team | IHC Biomarker/prognostic tests REFLEXED by UVMMC pathology |
| Biliary Tract | MMR and HER2 (GI) if not already done. | MMR and HER2 (GI) reflexed by pathology. Advanced: MMR and HER2 and Molecular. |
| Bladder | HER2 (Breast scoring-used most often in literature). | None |
| Breast | PD-L1 for Triple negative breast cancer. | ER/PR/HER2 |
| CUP-Carcinoma Unknown Primary | HER2 (breast scoring), MMR, PD-L1 (CPS). | None |
| Central Nervous System | None | As per routine. |
| Colorectal | HER2 (GI scoring) (based on 2025 NCCN). | MMR and HER2. Advanced: MMR and HER2 and Molecular. |
| Esophageal/EGJ | Eso/EGJ Adenocarcinoma: CLDN18, HER2, MMR, PD-L1 Eso/EGJ. Squamous cell ca: MMR, PDL1 if not already done. | Adenocarcinoma: CLDN18, HER2, MMR, PD-L1. Squamous cell ca: MMR, PDL1 if advanced molecular also ordered. |
| Gastric | Gastric adenocarcinoma: HER2-GI, MMR, PDL1, Claudin 18 if not already done. | Gastric adenocarcinoma: HER2-GI, MMR, PDL1, Claudin 18 if advanced molecular also ordered. |
| Head and Neck | HNSCC Squamous Cell Carcinoma: HER2 (GI scoring). Salivary Gland Carcinoma: HER2 (breast scoring). | PD-L1 in all HNSCC (except p16 + OroP HNSCC). Advanced HNSCC: peth reflex PD-L1, Her. |
| Hepatocellular | None | None |
| Melanoma | None | None |
| NSCLC | PD-L1 | Stage 1B NSCLC or higher stage (called advanced) reflex PDL1 and Molecular. |
| Pancreatic | MMR and HER2 (GI) if not already done. | MMR and HER2 (GI). If advanced: MMR and HER2 as well as Molecular. |
| Prostate | None (based on 2025 NCCN). | None |
| Renal | None (based on 2025 NCCN). | None |
| Soft Tissue Sarcoma | None (based on 2025 NCCN). | None |
| Thyroid | None (based on 2025 NCCN). | None |
| Other | None, have a Comment section to add on IHC. | None |
