Treatment for thyroid papillary cancer after nonstandard operation / 中华耳鼻咽喉头颈外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the disadvantage of nonstandard operation for thyroid papillary cancer, and the value of re-operation.</p><p><b>METHODS</b>Eight hundred and ninety three thyroid papillary cancer patients (332 patients who received nonstandard operation received re-operation and 561 patients who received first standard operation in Zhejiang Cancer Hospital from January 1990 to January 2000) were retrospectively reviewed.</p><p><b>RESULTS</b>Pathological results confirmed that there were 53.9% cases with residual cancer in re-operative specimen. The parathyroid was preserved in 74.1% cases in re-operation and 93.0% cases in standard operation (P < 0.01). The recurrent laryngeal nerve was injured in 3.3% cases in reoperation and 1.2% cases in standard operation (P < 0.05). The positive neck lymph node was 39.2% and 37.4% (P > 0.05), the 5-year local recurrence rate was 7.5% and 3.7% (P < 0.01), the total 5-year and 10-year cum-survival rates were 90.2%, 84.4% in patients with re-operation and 94.0%, 92.5% in patients with standard operation. The 10-year cum-survival rate were 67. 8% in patients with recurrence and 92. 9% in patients with non-recurrence in primary site respectively. Statistical analysis showed that the cancer recurrence influences the survival rate significantly (P < 0.01).</p><p><b>CONCLUSIONS</b>In consideration of the higher residual tumor rate in patients who received nonstandard operations, the re-operations were necessary. But the re-operation could also leads to higher recurrence rate and more functional injuries. The standardized primary operation should therefore be formulated and advocated.</p>
