Hypothesis
Does the level of preoperative serum thyrotropin (TSH) correlate with the presence and size of thyroid cancer?
Conclusion
Higher TSH levels are associated with a diagnosis of differentiated thyroid carcinoma (DTC) and increase with tumor size.
Supporting Evidence
- The mean TSH concentration was 1.36 mU/L in benign patients and 2.08 mU/L in malignant cases.
- Significant differences in TSH levels were found between benign and larger thyroid cancers.
- Higher TSH levels were associated with more advanced cancer stages.
Takeaway
The more TSH you have in your blood, the more likely it is that you have thyroid cancer, especially if the cancer is bigger.
Methodology
The study evaluated preoperative serum TSH levels in 386 patients with nodular thyroid disease and compared levels between benign and malignant cases.
Potential Biases
Potential bias due to the exclusion of patients with known thyroid cancer and those without available TSH levels.
Limitations
The study did not analyze thyroid antibodies in a quarter of patients, which may affect results.
Participant Demographics
The benign group included 250 females (80.6%) and 60 males (19.4%), with a mean age of 54.4 years; the malignant group included 60 females (78.9%) and 16 males (21.1%), with a mean age of 49.3 years.
