Thesis topics in thyroid cancer for a Surgical Oncology resident

1. Extent of surgery in differentiated thyroid cancer

1. Oncologic and functional outcomes of thyroid lobectomy versus total thyroidectomy for unilateral low-risk papillary thyroid carcinoma (1-4 cm).
   • Outcomes: recurrence, completion thyroidectomy, need for radioactive iodine, hypothyroidism, recurrent laryngeal nerve injury, hypocalcemia.
   • Highly current because the 2025 ATA guidance favors lobectomy for selected unilateral cT1N0M0 tumors up to 2 cm.
2. Predictors of completion thyroidectomy after initial lobectomy for differentiated thyroid cancer.
   • Useful if your institution increasingly adopts a lobectomy-first policy.
3. Does total thyroidectomy improve recurrence-free survival in intermediate-risk papillary thyroid carcinoma?
   • Retrospective propensity-matched cohort.
4. Clinical significance of contralateral nodules in patients undergoing lobectomy for unilateral papillary thyroid carcinoma.

2. Active surveillance and avoiding overtreatment

1. Suitability and outcomes of active surveillance for papillary thyroid microcarcinoma in an Indian/your institutional population.
   • Study tumor growth, nodal progression, crossover to surgery, anxiety, and adherence to ultrasound follow-up.
2. Factors associated with progression during active surveillance of low-risk papillary thyroid microcarcinoma.
   • Variables: age, sex, tumor size, location near capsule/trachea/RLN, multifocality, BRAF status if available.
3. Patient-reported decision regret, anxiety, and quality of life after immediate surgery versus active surveillance for papillary thyroid microcarcinoma.
   • Strong prospective thesis topic with validated questionnaires.
4. Role of ultrasound risk features in selecting papillary microcarcinoma patients for surgery versus surveillance.

3. Central and lateral neck dissection

1. Prophylactic central neck dissection in clinically node-negative papillary thyroid cancer: recurrence benefit versus morbidity.
   • Outcomes: locoregional recurrence, permanent hypoparathyroidism, RLN palsy, reoperation.
2. Can preoperative ultrasound and CT reliably predict central compartment nodal metastasis in papillary thyroid carcinoma?

• Diagnostic accuracy study correlated with final histopathology.

1. Predictors of lateral cervical lymph-node metastasis in clinically node-negative papillary thyroid carcinoma.

• Develop a practical risk score using tumor size, upper-pole site, multifocality, extrathyroidal extension, and central node burden.

1. Lymph-node ratio versus absolute metastatic lymph-node count as a predictor of recurrence after therapeutic neck dissection.
2. Patterns of recurrence after therapeutic lateral neck dissection for papillary thyroid carcinoma.

4. Surgical complications and quality improvement

1. Risk factors for transient and permanent hypoparathyroidism after total thyroidectomy with or without central neck dissection.

• Very feasible and clinically valuable. Include calcium, PTH, vitamin D status, gland autotransplantation, specimen parathyroid tissue, and surgeon volume.

1. Value of early postoperative parathyroid hormone measurement in predicting clinically significant hypocalcemia after thyroidectomy.
2. Effect of intraoperative nerve monitoring on recurrent laryngeal nerve outcomes in thyroid cancer surgery.

• Compare intermittent versus continuous monitoring if applicable.

1. Voice outcomes after thyroidectomy for cancer: correlation between laryngoscopy, nerve monitoring, and patient-reported Voice Handicap Index.
2. Impact of surgeon volume and multidisciplinary care on thyroidectomy outcomes for thyroid malignancy.

5. Preoperative diagnosis and risk prediction

1. Accuracy of Bethesda cytology combined with ultrasound risk stratification in predicting malignancy and aggressive pathology.
2. Can molecular testing alter the extent of initial surgery in indeterminate thyroid nodules?

• Feasible only if molecular testing is routinely accessible.

1. Predictors of gross extrathyroidal extension in papillary thyroid carcinoma: a preoperative clinicoradiologic model.
2. Preoperative prediction of recurrent laryngeal nerve invasion in locally advanced thyroid cancer.
3. Association of BRAF V600E mutation with nodal metastasis, recurrence, and extent of surgery in papillary thyroid carcinoma.

• Molecular status should be interpreted cautiously. Current guidance does not advise routine postoperative molecular profiling solely for all patients, though available results may refine risk assessment, as described in this postoperative ATA guideline review.

6. Locally advanced and recurrent disease

1. Outcomes of surgery for locally advanced differentiated thyroid carcinoma with tracheal, esophageal, or recurrent laryngeal nerve involvement.
2. Management and oncologic outcomes of recurrent nodal papillary thyroid carcinoma: reoperative surgery versus nonsurgical approaches.
3. Predictors of morbidity during reoperative central neck dissection for recurrent thyroid cancer.
4. Role of preoperative cross-sectional imaging in surgical planning for invasive thyroid carcinoma.
5. Surgical outcomes in radioiodine-refractory differentiated thyroid cancer with locoregional disease.

7. Rare, aggressive, and high-impact cancers

1. Clinicopathological profile and surgical outcomes of medullary thyroid carcinoma at a tertiary cancer center.

• Include calcitonin, RET testing availability, nodal disease, biochemical cure, and recurrence.

1. Central and lateral nodal burden as predictors of biochemical persistence in medullary thyroid carcinoma.
2. Multimodal management and survival outcomes in anaplastic thyroid carcinoma.

• Likely requires a long time period or multi-institutional collaboration due to rarity.

1. Outcomes of airway procedures in anaplastic thyroid carcinoma: tracheostomy, debulking, and nonsurgical palliation.
2. Poorly differentiated thyroid carcinoma: presentation, treatment patterns, and survival in a single-center cohort.

8. Newer surgical approaches and technology

1. Remote-access or robotic thyroidectomy versus conventional open thyroidectomy for selected differentiated thyroid cancers: safety, completeness, cosmetic satisfaction, and recurrence.
2. Is fluorescence-guided parathyroid identification associated with lower postoperative hypocalcemia in thyroid cancer surgery?
3. Role of carbon nanoparticle or other nodal mapping techniques in central compartment dissection.
4. Cost-effectiveness of robotic/remote-access thyroidectomy in a resource-constrained setting.

Best practical choices

1. Predictors of permanent hypoparathyroidism after total thyroidectomy with or without central neck dissection
2. Lobectomy versus total thyroidectomy for low-risk papillary thyroid carcinoma
3. Predictors of occult central/lateral nodal metastasis in clinically node-negative papillary thyroid carcinoma
4. Prophylactic central neck dissection: recurrence versus complication trade-off
5. Outcomes of reoperative neck dissection for recurrent papillary thyroid carcinoma
6. Active surveillance eligibility and progression predictors in papillary thyroid microcarcinoma
7. Clinicopathological outcomes of medullary thyroid carcinoma
