    • Validated predictive model for treatment and prognosis of adrenocortical carcinoma.

      Surgery 2024 Mar

      Authors: Zuber SM, Kuchta K, Holoubek SA, Khokar A, Moo-Young T, Prinz RA, Winchester DJ
      Adrenocortical carcinoma has a poor prognosis and multiple clinical, pathological, and treatment variables. Currently, we lack a prognostic and treatment calculator to determine the survival and efficacy of adjuvant chemoradiation. We aimed to validate a calculator to assess prognosis and treatment.
      We searched the National Cancer Database to identify patients with adrenocortical carcinoma surgically treated from 2004 to 2020 and randomly allocated them into a training (80%) or validation set (20%). We analyzed the variables of age; sex; Charlson Comorbidity Index; insurance status; tumor size; pathologic tumor, node, and metastasis categories; surgical margins; and use of chemotherapy and radiation therapy. We used Cox regression prediction models and bootstrap coefficients to generate a mathematical model to predict 5- and 10-year overall survival. After using the area under the curve analysis to assess the model's performance, we compared overall survival in the training and validation sets.
      Multivariable analysis of the 3,480 patients included in the study revealed that all variables were significant except sex (P < .05) and incorporated into a mathematical model. The area under the curve for 5- and 10-year overall survival was 0.68 and 0.70, respectively, for the training set and 0.70 and 0.72, respectively, for the validation set. For the bootstrap coefficients, the 5- and 10-year overall survival was 6.4% and 4.1%, respectively, above the observed mean.
      Our model predicts the overall survival of patients with adrenocortical carcinoma based on clinical, pathologic, and treatment variables and can assist in individualizing treatment.

    • Treatment Differences for Adrenocortical Carcinoma by Race and Insurance Status.

      The Journal of surgical research 2022 Dec

      Authors: Holoubek SA, MacKinney EC, Khokar AM, Kuchta KM, Winchester DJ, Prinz RA, Moo-Young TA
      To determine if treatment and clinical outcomes of adrenocortical carcinoma (ACC) vary by race and insurance status.
      ACC patients from the National Cancer Database (2004-2017) were reviewed. Race was defined as White versus minority (Black and Hispanic). Insurance types were private (PI) versus other (Medicaid/uninsured/unknown). Metastatic ACC (M-ACC) was defined as distant metastases at the time of diagnosis; nonmetastatic ACC (NM-ACC) patient had no distant disease.
      Of 2351 NM-ACC patients, 83.6% were White and 16.4% minority. There were 1216 M-ACC patients, with 80.3% White and 19.8% minority. Both White NM-ACC and M-ACC patients had more PI (each P < 0.001). PI NM-ACC was associated with a shorter duration from diagnosis to first treatment (14 versus 18 d, P = 0.005). Both NM-ACC and M-ACC with PI were more likely to receive surgery (92.6% versus 86.9%, P = 0.001 and 35.4% versus 27%, P = 0.02) and to receive surgery sooner (13 versus 16 d, P = 0.03). M-ACC with PI were more likely to receive chemotherapy (63.6% versus 54.3%, P = 0.01) and to have lymph nodes examined (14.8% versus 8.6%, P = 0.02). Length of stay postoperatively was shorter for White NM-ACC (6 versus 7 d, P = 0.04) and M-ACC (8 versus 17 d, P = 0.02). For NM-ACC and M-ACC, the 30-d readmission, 90-d mortality, and overall survival were similar by race. A multivariable analysis showed minorities (OR 0.69, 95% confidence interval 0.54-0.88, P = 0.003) and patients without PI (OR 0.75, 95% confidence interval 0.58-0.97, P = 0.03) were less likely to have surgery. However, a multivariable analysis showed survival was similar for White versus minority patients and PI versus other.
      White NM-ACC or M-ACC and PI were more likely to receive surgery and timely multimodality care. These disparities were not associated with differences in 90-d mortality or overall survival.

    • Treatment differences at high volume centers and low volume centers in non-metastatic and metastatic adrenocortical carcinoma.

      American journal of surgery 2022 Mar

      Authors: MacKinney EC, Holoubek SA, Khokar AM, Kuchta KM, Moo-Young TA, Prinz RA, Winchester DJ
      Adrenocortical carcinoma (ACC) is rare with poor survival. Do treatment and outcomes vary by volume?
      NCDB (2004-2017) was searched for patients with ACC. High-volume centers (HVCs) were defined by ≥ 15 ACC and low-volume centers by ≤ 7 total cases. Multivariable Cox and logistic regression analysis were performed.
      ACC patients at HVCs were significantly more likely to have surgery, chemotherapy, and had lower 90-day readmission. HVCs were significantly more likely than LVCs to administer chemotherapy to surgical NonMetastatic (NM)-ACC patients. There was no significant difference in overall survival (OS), 90-day mortality, length of stay, or radiation treatments between the two. Operative Metastatic (M)-ACC at HVC had significantly improved OS, more chemotherapy administered, and lower 90-day mortality.
      NM-ACC and M-ACC treated at HVCs were more likely to have surgery and multimodality therapy. NM-ACC having surgery at HVCs and LVCs had similar OS. M-ACC at HVCs had improved OS and 90-day mortality.

    • Overall survival is improved with total thyroidectomy and radiation for male patients and patients older than 55 with T2N0M0 Stage 1 classic papillary thyroid cancer.

      Surgery 2022 Jan

      Authors: MacKinney EC, Kuchta KM, Winchester DJ, Khokar AM, Holoubek SA, Moo-Young TA, Prinz RA
      We examine whether surgery extent and radiation administration affect overall survival for cT2N0M0 classic papillary thyroid cancer according to age and sex.
      Patients with cT2N0M0 classic papillary thyroid cancer tumors in the National Cancer Data Base (2004-2016) were selected. Multivariable Cox regression analysis compared patients (combined male + female cohorts) having lobectomy to those having total thyroidectomy with or without radiation (primarily radioactive iodine) for ages: 18 to 45, 46 to 55, and >55 years. In addition, 1:1 propensity score matching and Kaplan-Meier curves with 10-year overall survival estimates, and log-rank test were stratified by age and sex.
      Lobectomy had equivalent overall survival to total thyroidectomy without and with radiation for patients (combined male + female cohorts) aged 18 to 45 and 46 to 55 years on multivariable analysis. On propensity score matching there was overall survival advantage for total thyroidectomy with radiation over both lobectomy and total thyroidectomy for men (ages 18-90+ combined) and overall survival advantage in patients (combined male + female cohort) aged >55 years having total thyroidectomy with radiation versus lobectomy. On propensity score matching there were no overall survival differences in women (ages 18-90+ combined) or patients (combined male + female cohort) aged 18 to 45 and 46 to 55 years having either lobectomy, total thyroidectomy, or total thyroidectomy with radiation.
      For cT2N0M0 classic papillary thyroid cancer, total thyroidectomy with radiation improves 10-year overall survival for patients (combined male + female cohort) aged >55 years and men (ages 18-90+ combined).

    • Radioactive iodine does not improve overall survival for patients with aggressive variants of papillary thyroid carcinoma less than 2 cm.

      Surgery 2022 Jan

      Authors: Holoubek SA, MacKinney EC, Khokar AM, Kuchta KM, Winchester DJ, Prinz RA, Moo-Young TA
      Tall cell and diffuse sclerosing variants of papillary thyroid cancer are associated with aggressive features. Radioactive iodine after total thyroidectomy is poorly studied.
      Patients ≥18 years in the National Cancer Data Base from 2004 to 2016 with classic papillary thyroid cancer, tall cell, or diffuse sclerosing 1 mm to 40 mm were identified. Logistic regression identified factors associated with aggressive features. Overall survival was assessed using Kaplan-Meier method and log-rank tests, after propensity score matching for clinicopathological and treatment variables.
      A total of 155,940 classic papillary thyroid cancer patients, 4,011 tall cell, and 507 diffuse sclerosing were identified. Tall cell patients represented an increasing proportion of the study population during the analysis period, whereas diffuse sclerosing and classic papillary thyroid cancer patients showed a statistically significant decline. Extrathyroidal extension and nodal involvement were more prevalent among tall cell and diffuse sclerosing patients when compared to those diagnosed with classic papillary thyroid cancer (P < .01). Adjuvant radioactive iodine was less frequently used in patients with classic papillary thyroid cancer when compared to tall cell and diffuse sclerosing patients (42.6% vs 62.4%, 59.0%; P < .001, respectively). Aggressive variants receiving total thyroidectomy versus total thyroidectomy + radioactive iodine propensity score matched across clinicopathologic variables were analyzed. There was no difference in overall survival between the 2 treatment groups for tumors <2 cm (01-1.0 cm, 92.2% vs 84.8%; P = .98); (1.0-2.0 cm, 72.7% vs 88.1%; P = .82). However, overall survival was improved for total thyroidectomy + radioactive iodine propensity score matched patients with tumor sizes 21 to 40 mm versus total thyroidectomy (83.4% vs 70.0%, P = .004).
      For aggressive tumor variants ≤2 cm treated with total thyroidectomy, there is no overall survival advantage provided by the addition of adjuvant radioactive iodine.

    • Radioactive iodine-125 seed localization as an aid in reoperative neck surgery.

      American journal of surgery 2021 Mar

      Authors: Bortz MD, Khokar A, Winchester DJ, Moo-Young TA, Ecanow DB, Ecanow JS, Prinz RA
      Scarring and disrupted tissue planes add to already-complex neck anatomy and make localization of nonpalpable pathology difficult in cervical endocrine reoperations. We describe the use of radioactive iodine-125 seed localization (RSL) in 6 patients with metastatic papillary thyroid carcinoma (PTC) and 2 with recurrent hyperparathyroidism.
      Eight patients had 2-D ultrasound-guided RSL of the target lesion, 0-3 days preoperatively. Intraoperative gamma probe (Neoprobe) was used to plan incision placement and localize the implanted seed. Recorded operative variables included: number of lymph nodes (LNs) harvested, estimated blood loss (EBL), operative time, length of stay (LOS) and RSL and operative complications.
      All patients had successful resection of the targeted area and removal of the radioactive seed. There was no seed migration. Two complications occurred in the thyroid group.
      Radioactive iodine 125 seeds facilitate successful localization of endocrine pathology during reoperative cervical procedures.

    • Extrathyroidal extension predicts negative clinical outcomes in papillary thyroid cancer.

      Surgery 2021 Jan

      Authors: Bortz MD, Kuchta K, Winchester DJ, Prinz RA, Moo-Young TA
      The eighth edition American Joint Committee on Cancer tumor-node-metastasis staging for well-differentiated thyroid cancers, no longer considers "minimal" extrathyroidal extension for tumor staging. This change prompted us to examine the effect of extrathyroidal extension on patient outcomes.
      Patients (n = 177,497) in the 2016 National Cancer Database with classic papillary thyroid cancer were evaluated to determine the effect of extrathyroidal extension on overall survival and risk for nodal and distant metastases. Kaplan-Meier curves with the log-rank test were used to evaluate survival differences. Multivariable Cox and logistic regression analyses included relevant clinicopathologic variables (e.g. age, sex, race, and Charlson Comorbidity Index).
      Patients with "minimal" extrathyroidal extension had worse survival versus patients with no extrathyroidal extension (10-year survival 89.3% vs 93.1%, hazard ratio 1.23; 95% confidence interval, 1.13-1.35; P < .001). Any extrathyroidal extension was associated with higher risks for lymph node (odds ratio 2.78; 95% confidence interval, 2.69-2.87) and distant metastasis (odds ratio 3.5; 95% confidence interval, 3.05-4.04). These associations persisted when comparing "micro" (extension into the thyroid capsule) versus none for nodal risk (odds ratio 1.25; 95% confidence interval, 1.18-1.33) and distant metastasis (OR 1.52; 95% confidence interval, 1.11-2.09).
      All levels of extrathyroidal extension, including microscopic, were associated with increased risk for nodal and distant metastasis. Both minimal and macroscopic extrathyroidal extension were also associated with decreased overall survival. Such findings have the potential to affect the clinical decision making for patients diagnosed with papillary thyroid cancer.

    • Trends in nonoperative management of papillary thyroid microcarcinoma.

      Journal of surgical oncology 2020 May

      Authors: Holoubek SA, Yan H, Kuchta KM, Winchester DJ
      In 2010, a Japanese trial of nonoperative management for papillary thyroid microcarcinomas (PTmC) was published. This study determines if the prevalence of nonoperative management in the United States has changed and if there are predictors of this approach.
      Patients treated for PTmC between 2004 and 2015 in the National Cancer Data Base were identified. Inclusion criteria were: classic or follicular variant papillary cancer histology, tumor size 1 to 10 mm, cN0 disease and no extrathyroidal extension or metastatic disease. Nonoperative management was assessed over time and compared between 2004-2010 and 2010-2015. Logistic regression identified factors associated with nonoperative management.
      Of 65 381 PTmC patients, 344 (0.5%) were treated nonoperatively. The annual rate of nonoperative management was similar at 0.6% in 2004 to 0.4% in 2010 (P = .755) but increased to 0.9% in 2015 (P < .001). There was no difference in patient age, race, comorbidities, or reason for nonoperative management between the two periods. Academic centers managed more patients nonoperatively. Multivariable logistic regression suggests older age, facility type, location, Hispanic, Asian, and Native American ethnicity were associated with nonoperative management.
      The vast majority of PTmC in the United States is treated with an operation. A small but significant increase in nonoperative management occurred between 2004-2010 and 2010-2015.

    • Survival with Follicular and Hurthle Cell Microcarcinoma Compared to Papillary Thyroid Microcarcinoma: A Population Study of 84,532 Patients.

      World journal of surgery 2020 Feb

      Authors: Khokar AM
      This study compares survival in patients with the rare subtypes of follicular (FTmC) and Hurthle cell (HCmC) microcarcinoma compared to that of papillary thyroid (PTmC) microcarcinoma.
      Patients with FTmC and HCmC were selected from the National Cancer Database 2004-2015 and compared with PTmC. Patient clinicopathological characteristics and overall survival (OS) were analyzed. Multivariable logistic and Cox regression analysis evaluated binary outcomes and predictors of survival. A propensity score matched analysis using age, gender, race, extrathyroidal extension (ETE), nodal status, distant metastasis, radiation, and operation was performed to evaluate the difference in OS with FTmC, HCmC, and PTmC.
      We identified 858 FTmC, 476 HCmC, and 82,056 PTmC. FTmC was less likely to have macroscopic ETE compared to PTmC (2.6% vs. 3.1% p = 0.03), but more likely to have distant metastasis (2.3% vs. 0.2%, p < 0.01). FTmC and HCmC were less likely to have nodal metastasis (2.7%, 2.5% vs. 10.9%, p < 0.01). Ten-year OS was decreased in patients with FTmC (91.4%, p = 0.04) and HCmC (89.8%, p < 0.01) compared to PTmC (93.5%). On multivariable analysis, histology was not associated with OS. With HCmC, older age (OR 1.13, p < 0.01) and male gender (OR 2.72, p = 0.03) were associated with decreased OS. In propensity matched analysis, there was no difference in 10-year OS with FTmC and PTmC (91.4% vs. 93.7%, p = 0.54), but HCmC had decreased OS compared to PTmC (89.8% vs. 94.3%, p = 0.04).
      Patients with FTmC have comparable OS to those with PTmC, but HCmC has decreased OS especially in older and male patients.
