Enrollment: 200
Study Start Date: May 2004
Study Completion Date: February 2006
Primary Completion Date: February 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: C
No supplements after total thyroidectomy and central neck dissection
No Intervention: D
No central neck dissection group (total thyroidectomy alone)
Active Comparator: A
Oral calcium plus vitamin D supplements after total thyroidectomy and central neck dissection
Dietary Supplement: Oral calcium plus vitamin D
calcium supplementation took 3 g/day oral calcium (1 g every 8 h) plus 1 mcg/day vitamin D (0.5 mcg every 12 h), beginning on the night of surgery and continuing for 14 days.
Other Name: calcium carbonate and one-alpha (vitamin D)
Active Comparator: B
Oral calcium alone supplement after total thyroidectomy and central neck dissection
Dietary Supplement: Oral calcium alone
calcium carbonate (3 g/day, 1 g every 8 h)
Other Name: calcium carbonate (Korea United Pharmaceutical Co, Seoul, Korea)

Detailed Description:
Of patients with differentiated papillary thyroid carcinoma, group D underwent total thyroidectomy alone and groups A-C underwent total thyroidectomy plus CND. The latter were randomized to oral calcium (3 g/day) plus vitamin D (1 mcg/day) (group A, n = 49), calcium alone (group B, n = 49), or no supplements (group C, n = 50). Hypocalcemic symptoms, serum calcium, and parathyroid hormone (PTH) levels were compared among the groups.
