Dr.Guttler’s comments:

1.Old rules= whole thyroid removed.

2. Half thyroid removed= status with complete removal of the gland.

3.Before 2015, 15.6 percent of patients with thyroid cancer had half removal.

4. After  2015 the % half removal has continued to rise.

5.The trend could be significant for improving outcomes and reducing costs of care for people with thyroid cancer.

6.Half removal has several known advantages.

7.One third of patients treated with half removal will have enough thyroid ‘left over’ after the operation and will not need to take daily thyroid hormone.

8.Less aggressive nature of half removal = less complications.

9.Less recurrent nerve and parathyroid/calcium problems.

10. More outpatient treatment outside the hospital.

11. Less Hospital stays lower the risk of superficial surgical-site infections and unplanned bleeding with the need for breathing tube.

12.However, whole removal rate of over 80 percent in the fourth quarter of 2016 is still too high, and that many more patients can be safely treated with a half instead of whole.

13. Your endocrinologist must question the surgeon that wants to remove the whole gland.

Guideline recommending removal of half the thyroid gland benefits thyroid cancer patients

American College of Surgeons

The study findings showed that, before the American Thyroid Association (ATA) adopted its new guidelines in 2015, 15.6 percent of patients with thyroid cancer underwent a hemithyroidectomy. In the year after the new ATA guidelines were released, that rate had increased to 18.3 percent (p<0.001). The findings also showed that following publication of the guidelines, the growth in the percentage of patients treated with hemithyroidectomy among participating surgeons increased more than sevenfold, from 0.12 to 0.87 percent per quarter year (p=0.006).

The trend could be significant for improving outcomes and reducing costs of care for people with thyroid cancer. “Hemithyroidectomy has several known advantages for patients over total thyroidectomy,” said Timothy M. Ullmann, MD, a general surgery resident at Weill Cornell Medical College, New York-Presbyterian Hospital in New York. “First, since about half of the thyroid gland is left in place, about one third of patients treated with hemithyroidectomy will have enough thyroid ‘left over’ after the operation and will not need to take daily thyroid hormone supplement pills.”

Second, the less aggressive nature of hemithyroidectomy means less trauma to surrounding anatomy. “There are many structures in the neck that are near the thyroid gland, including the parathyroid glands (which control calcium levels in the blood) and the nerves controlling the vocal cords,” Dr. Ullmann explained. “These structures are behind both sides, or lobes, of the thyroid gland and can be injured during a thyroid procedure. However, since patients undergoing hemithyroidectomy only have the operation performed on one side of the neck, it is not possible to injure all the parathyroid glands or the nerves on both sides, and, thus, the complication risk is much lower.”

Additionally, hemithyroidectomy patients were more likely to have an outpatient procedure (69.9 vs. 52.9 percent, p<0.001), spend less time in the hospital (zero to one day vs. one day, p<0.001), and have half the risk of superficial surgical-site infections (0.2 vs. 0.4 percent, p<0.001) and unplanned breathing tube reinsertions (0.2 vs. 0.5 percent, p<0.001).

In a separate analysis, the researchers found that the rates of patients who had hemithyroidectomy and then needed a second operation for removing the remaining half of the thyroid gland, known as a completion thyroidectomy, were no different before and after the revised guidelines.

“Completion thyroidectomy is done to enable treatment with radioactive iodine and reduce the risk of cancer recurrence in patients with aggressive or advanced-staged cancers,” Dr. Ullmann said. “If these patients had more aggressive or later-stage cancers, or if they had more cancers that were found incidentally (and surgeons did not feel they were adequately treated for their cancers with hemithyroidectomy alone), we would expect the completion thyroidectomy rate to increase.”

The researchers surveyed 33,984 operations for thyroid cancer at member institutions entered into the ACS NSQIP database from 2009 to 2016. Seventy-five percent of study patients were female. NSQIP is a nationally validated, risk-adjusted, outcomes-based program to measure and improve the quality of surgical care in participating hospitals.

“We think that these results are important because this data suggests that surgeons at NSQIP hospitals are following the newest ATA guidelines,” Dr. Ullmann said. “However, we believe that a total thyroidectomy rate of over 80 percent in the fourth quarter of 2016 is still too high, and that many more patients can be safely treated with a hemithyroidectomy.”

Dr. Ullmann said the hope is that the trend toward hemithyroidectomy continues and that more surgeons realize the procedure is a safe option for most patients with thyroid cancer. “Ultimately, our goal is to make surgeons more secure in the knowledge that their peers are also changing their practice patterns, so that they will be more encouraged to take the ‘less is more’ approach that the ATA recommends,” he said.
