Peter Sadow studies the early detection and management of head and neck cancers, particularly those linked to the human papillomavirus (HPV), and various types of thyroid cancers. He has developed blood tests that can identify cancer DNA in patients after surgery, allowing doctors to predict relapses and determine if further treatment is necessary. Sadow also investigates genetic mutations in thyroid tumors, helping to clarify the potential risks associated with these mutations and guiding treatment strategies for patients with complex thyroid issues.

This study looked at a special type of immune cell called CCR7 dendritic cells in tumors to understand how their location affects the body’s ability to fight cancer. Researchers found that these cells cluster near blood vessels, and when they interact with regulatory immune cells, they can become suppressed and less effective at activating T cells, which are crucial for fighting tumors. By removing regulatory cells or using certain cancer treatments, they were able to boost the action of CCR7 dendritic cells and improve T cell responses in treating tumors.

Researchers studied how to better classify and understand the severity of renal pelvic urothelial carcinoma, a type of kidney cancer, by analyzing 141 patients who had surgery. They found that the current staging system (called TNM) does not effectively predict survival differences for many tumor stages. However, by simplifying the staging criteria, they revealed that tumors invading the outer layer of the kidney (cortex) are linked to much poorer survival rates compared to those that do not.
Who this helps: This helps doctors better predict patient outcomes and tailor treatment for kidney cancer patients.

Researchers studied different types of tumors found in the salivary glands, specifically looking at certain benign and early-stage cancerous lesions linked to a condition called pleomorphic adenoma. They found that many of these lesions, even with some unusual cell features, do not lead to recurrence or spread of cancer if they remain contained within the tumor. This is important because it suggests that some terms used to describe these lesions might cause unnecessary worry and treatment, and simpler names that reflect their generally harmless nature could be more appropriate.

Adenoid cystic carcinoma (ACC) is a deadly cancer that doesn't respond well to current treatments because tumors hide from the immune system—they have very low levels of a protein called HLA class I that the immune system needs to recognize and attack cancer cells. Researchers discovered that treating ACC tumors with immune-activating drugs called STING agonists can turn this protein back on, and when they tested this approach in one patient combined with an existing immunotherapy drug, the tumor shrank by 70%. This finding suggests that turning HLA class I back on with STING agonists could finally make immunotherapy work for ACC patients.

Researchers developed a new blood test using advanced DNA sequencing to detect HPV-associated head and neck cancers early, before symptoms appear, and compared it to three other blood-based detection methods. The new sequencing test detected cancer 98.7% of the time it was present and correctly identified healthy people 98.7% of the time—significantly better than existing blood tests. This breakthrough matters because HPV-related head and neck cancers are becoming more common, yet doctors currently have no way to catch them early when treatment is most effective.

Researchers developed a highly sensitive blood test that detects tiny amounts of HPV cancer DNA left in patients after surgery for HPV-related head and neck cancer. They found that patients whose blood still contained this cancer DNA had much worse outcomes—only 60% stayed cancer-free for 2 years compared to 100% of patients with no detectable DNA—and this blood test was better at predicting who would relapse than current methods doctors use.
The test could also spot cancer coming back up to 17 months before it shows up on scans or causes symptoms, giving doctors an early warning system to decide whether patients need additional treatment like chemotherapy or radiation.

This study looked at a rare type of testicular tumor called spermatocytic tumors (STs), which primarily affect older men. Researchers analyzed 27 samples from 25 patients and found two main types of STs: one type had specific mutations associated with cancer, while the other did not. They discovered that aggressive tumors often had mutations in a gene called TP53 and changes in chromosome 12, which suggest these tumors might behave similarly to other more serious forms of testicular cancer.
Who this helps: This research benefits doctors and patients by providing insights into how some spermatocytic tumors might develop into more aggressive forms.

They found that unusual spread patterns—where cancer appears in lower neck levels while skipping the upper levels—happened in only 5% of patients. These results suggest surgeons may be able to safely skip removing lymph nodes from the lowest neck level in some HPV-positive throat cancer patients, potentially reducing surgery complications without compromising cancer treatment.

Researchers injected a near-infrared dye called indocyanine green into cancer patients and found that cancer cells glow differently than healthy cells when measured by how long the glow lasts (rather than how bright it is). This difference in glow duration remained consistent across different cancer types and could identify tumors with over 97% accuracy, even at the cellular level.
This matters because current surgical imaging techniques rely on brightness, which varies depending on how much dye the tumor absorbed and how deep it is in the body—making it hard to distinguish cancer from healthy tissue. Since the glow duration is a stable property of the dye itself, it could help surgeons more reliably spot and remove all cancerous tissue during operations.
