Getting Your Foot in the Door: Access to Surgical Care for Thyroid Disease

Racial implications of time to surgery in disparities in thyroid cancer survival

INTRODUCTION

The influence of time to surgery on racial/ethnic disparities in papillary thyroid carcinoma (PTC) survival remains unstudied.

MATERIALS AND METHODS

The National Cancer Database (2004-2017) was queried for patients with localized PTC. Survival data was compared by time to surgery, patient demographics, and multivariable Cox regression was performed.

RESULTS

Of 126,708 patients included, 5% were Black, 10% Hispanic. Of all patients, 85% had no comorbidities. Non-Hispanic White (NHW) patients had a shorter median time to surgery than Black and Hispanic patients (36 vs. 43 vs. 42 days, respectively p ​< ​0.001). In multivariable analysis, longer time to surgery (>90 days vs ​< ​30 days) and Black race vs NHW, were associated with worse survival (HR: 1.56, (95%CI, 1.43-1.70), p ​< ​0.001 and HR: 1.21, (1.08-1.36), p ​= ​0.001), respectively.

CONCLUSION

Delaying surgery for thyroid cancer is associated with worse survival. However, independent of time to surgery and other confounders, there remains a disparity as black patients have poorer outcomes.

The overtreatment of papillary thyroid microcarcinoma in the community

INTRODUCTION

Total thyroidectomy is the traditional primary approach for papillary thyroid cancer. However, recent evidence supports conservative management for low-risk tumors like papillary thyroid microcarcinomas (PTMCs). This study explores the adoption of these practices in our community, using a cancer database to analyze treatment strategies.

METHODS

A retrospective review of a 1433-patient institutional database identified 258 ​PTMC cases. Outcomes, including 30-day mortality, reoperation rate, postoperative hypocalcemia, and recurrent laryngeal nerve (RLN) injury, were assessed.

RESULTS

Of PTMC patients, 63.4% underwent total thyroidectomy, with higher rates of RLN injury (8.8% vs. 2.3%) and hypocalcemia (12.4% vs. 0.0%) compared to lobectomy. Non-endocrine surgeons had higher postoperative radioactive iodine administration rates (28.6% vs. 6.1%). Subgroup analysis revealed a shift in total thyroidectomy rates based on tumor size and surgery period.

CONCLUSION

Our community favors total thyroidectomy for PTMC, despite associated complications. Enhanced awareness and adherence to PTMC best practice guidelines are warranted.

Reducing disparities in the treatment of hyperparathyroidism

Background

Hyperparathyroidism is common with African American patients historically experiencing disparate outcomes. With a comprehensive outreach program and systematic treatment plans, we sought to evaluate our institution's ability to reduce disparities in hyperparathyroidism.

Methods

We performed a retrospective review of prospectively collected data at a single medical center for all patients undergoing parathyroidectomy by endocrine surgeons from 2015 to 2021 for primary (PHPT) and tertiary (THPT) hyperparathyroidism. Patient demographics, pre-and post-operative clinical and biochemical data were collected and analyzed by race.

Results

Of the 757 patients included, 675 patients had PHPT with 135 (20 %) African-American (AA) and 528(78 %) female. Of 82 patients with THPT, 44 (53 %) were AA and 34 (32 %) were female. AA patients were younger than Caucasian (CA) patients with a mean age (±SD) of 56 ± 15 vs 60 ± 14 years in PHPT (p < 0.01) and 50 ± 10 vs 55 ± 10 years in THPT (p = 0.02).Median (IQR) preoperative PTH was higher in AA with PHPT 134 (97-190) vs 102 (75-144) pg/mL (p < 0.01) and in AA with THPT 285 (189-544) vs 218 (145-293) (p = 0.01) pg/mL. AA PHPT patients had significantly higher preoperative mean (±SD) calcium levels 10.9 ± 0.8 vs 10.6 ± 0.8 mg/dL(p < 0.001). Biochemical cure rates at 6 months and complication rates were not different between races.

Conclusions

AA patients with PHPT and THPT disease experienced similar cure rates to their CA counterparts despite having a more severe biochemical disease. Health care disparities may be ameliorated with treatment by high volume surgeons embedded in a comprehensive health care system.
