NCT02138214

Brief Summary

This phase II trial studies how well thyroid gland removal with or without central lymph node dissection works in treating patients with thyroid cancer or suspected thyroid cancer that has not spread to the lymph nodes (randomized into Arms I and II). Arms I and II are compared to a standard of care (SOC) Arm III to enable comparison of quality of life among various surgical treatments. Currently, the standard treatment for thyroid cancer is total thyroidectomy, or complete removal of the thyroid. The lymph nodes in the central part of the neck may also be surgically removed, called central lymph node dissection. Prophylactic removal of the lymph nodes may increase the risk of life-threatening complications, and may reduce post-surgery quality of life. It may also prevent the cancer from returning and reduce the need for additional surgery. It is not yet known whether recurrence rates and complication levels are lower after thyroid gland removal alone or with central lymph node dissection.

Outcome Measures

Primary Outcomes (8)

  • Percentage of Participants With Transient Hypoparathyroidism, as Defined by a Day 1 Serum Parathyroid Hormone (PTH) Level of < 10 pg/ml

    Rate of transient hypoparathyroidism will be assessed in terms of percentage of participants with day 1 serum PTH level of \< 10 pg/ml.

    Post-operative day 1

  • Post-operative Serum Calcium (mg/dL) at Day 12

    Post-operative serum calcium (mg/dL) at Day 12

    At day 12

  • Total Calcium Consumption in First 2 Weeks

    Total calcium consumption in first 2 weeks (total mg). Participants were given calcium symptom logs in which to record their calcium consumption between surgery and their first preoperative follow up appointment, approximately two week.

    2 weeks after surgery

  • Number of Participants With Hypocalcemia Symptoms in First 2 Weeks

    Number of participants with hypocalcemia symptoms and symptom severity in first two weeks, as defined by presence of clinically significant symptoms of hypocalcemia. Clinically significant symptoms defined as 1 or more episodes of symptoms of hypocalcemia per day for multiple days, symptoms leading to calls to provider for assistance with managing and/or symptoms leading to escalation of dosage of prescribed medications to treat symptoms of hypocalcemia

    2 weeks

  • Hypocalcemia Symptom Severity Scale (Range of 1-5)

    Mean number of occurrences of mild (severity 1 - 2) and severe (severity 3 - 5) hypocalcemia symptoms. Participants were asked to record hypocalcemia symptoms between surgery and first postoperative follow-up at approximately two weeks in their provided calcium symptom logs and rank severity on scale of 1 (mild) to 5 (severe).

    2 weeks post surgery

  • Percentage of Participants That Required Calcium and Calcitriol at Month 6

    Requirement for calcium and calcitriol at Month 6 (or, if laboratory values at visit reveal calcium \< 8 mg/dL and PTH \<15 pg/ml)

    At Month 6

  • Post-operative Serum PTH (pg/ml) at Month 6

    At Month 6

  • Post-operative Serum Calcium Level at Month 6

    Post-operative serum calcium (mg/dL) at Month 6

    At Month 6

Secondary Outcomes (5)

  • Rate of Transient and Permanent Hypocalcemia

    Post-operative day 1 - Month 6

  • Rate of Voice and Swallowing Problems

    Post operative day 1 - up to 1 year

  • Degree to Which Quality of Life (QOL) is Compromised

    Post-operative day 1 - up to 1 year

  • Clinical Recurrence Rates

    Week 6 - up to 5 years

  • Degree to Which Accurate Quality of Life (QOL) Measures Can be Extracted From Patient Interview Narratives Using Natural Language Processing Techniques

    Post-operative day 1 - up to 1 year
