Background:
This systematic review and meta-analysis collected data for evaluating the effect of surgical extent on overall survival (OS) and recurrence-free survival (RFS) in patients with papillary thyroid cancer (PTC).
Methods:
We searched the PubMed, Embase, and Cochrane Library databases. The included studies compared two groups of patients with PTC: the total thyroidectomy (TT) group and the lobectomy (LT) group. The combined hazard ratio (HR) was calculated.
Results:
Thirteen studies were included in the present study. The TT and LT groups had similar OS results (HR = 1.04; 95% CI: 0.90-1.21; P = .60). In the subgroup analysis, the combined HR of the ≤1 cm group and the 1.0 to 2.0 cm group showed that TT had no advantage with regard to OS compared to LT. In the 2.0 to 4.0 cm group, TT provided better OS than LT (HR = 0.88; 95% CI: 0.79-0.99; P = .03). Patients who underwent TT had a better RFS outcome than those who underwent LT (HR = 0.56; 95% CI: 0.41-0.77; P < .0001). In the subgroup analysis, both the ≤1 cm group and >1 cm group that underwent TT were associated with better RFS.
Conclusions:
Our meta-analysis suggested that LT increased the risk of recurrence in PTC patients with tumors ≤1.0 cm and in PTC patients with tumors >1.0 cm. More importantly, LT was associated with higher mortality in PTC patients with 2.0 to 4.0 cm tumors. Caution is warranted when LT is performed in this group of patients.
