Summary
This summary is machine-generated.Minimal extrathyroid extension (mETE) and neck lymph node metastases are key predictors of papillary thyroid cancer recurrence. These factors, identified during surgery, indicate a more aggressive disease course and warrant consideration for revised AJCC staging.
Area Of Science
- Endocrinology
- Oncology
- Surgical Pathology
Background
- Papillary thyroid cancer (PC) recurrence prediction for T1b and T2 tumors (1-4 cm) is challenging.
- Identifying prognostic risk factors from primary tumor surgery is crucial for predicting disease progression.
Purpose Of The Study
- To evaluate the prognostic role of surgical risk factors in predicting disease progression in PC patients.
- To assess the association of minimal extrathyroid extension (mETE) and lymph node (LN) metastases with PC aggressiveness.
Main Methods
- Retrospective analysis of 363 PC patients (207 T1b, 156 T2) with follow-up data.
- Inclusion of tissue risk factors identified during primary tumor surgery.
- Utilized 131I-whole-body scan, SPECT/CT, US, histology, and needle biopsy for metastasis detection and validation.
Main Results
- Metastases occurred in 16.8% of patients (61/363).
- Minimal extrathyroid extension (mETE) and neck lymph node (LN) metastases were significant predictors of metastasis development (p < 0.001).
- These factors were associated with shorter disease-free survival.
Conclusions
- mETE and neck LN metastases are associated with aggressive PC and predict recurrence.
- The prognostic significance of mETE, previously downplayed by AJCC's eighth edition, is supported by this study.
- A revision of mETE classification in future AJCC editions is recommended.

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
Tumors may result in a case where two people have the same mutations in an oncogene or tumor...
Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
