[Abstract]:Objective To analyze the clinicopathological features of cervical lymph node metastasis in papillary thyroid carcinoma (PTC) and evaluate their value in the diagnosis of cervical lymph node metastasis. In February, 357 patients who underwent total thyroidectomy and selective cervical lymphadenectomy through a low-level neck incision in the General Surgery Department of the Gulou Hospital Affiliated to the Medical College of Nanjing University did not have clear enlarged lymph node negative (CN-) PTC and thyroid gland descending from an "L" incision at the same time. Seventy-eight patients with PTC who underwent functional lymphadenectomy for carcinoma were retrospectively analyzed.The extent of lymph node dissection included at least the ipsilateral central area (VI), the lymph nodes in areas IIa, III, IV and V b.Chi-square test or Fisher exact probability method were used to compare the extracapsular invasion, sex, age (45-year-old group and 45-year-old group) and area VI. Lymph nodes, primary lesion size (T < 1cm, 1cm T < 4cm and T4cm group), multifocal lesions, color Doppler ultrasonography lymph node characteristics, lateral, color Doppler ultrasonography cervical lymph node size (L1.5cm, 1L < 1.5cm and L < 1cm group) and cervical lymph node metastasis in the relationship, looking for the relevant clinical and pathological characteristics, comparing each related clinical and pathological characteristics of the cervical region lymph node metastasis. Influences were analyzed by principal component analysis (PCA). The variance of metastasis results was used to determine the degree of influence. The number of clinicopathological features and the number of clinicopathological features was used to determine the diagnostic value of lymph node metastasis in the cervical lateral region. The diagnostic value was evaluated by the area under the curve (AUC) of Youden index (YI) and receiver operating characteristic curve (ROC). The greater the YI and AUC, the greater the diagnostic value. There were significant differences in incision length, operative time, total number of lymph nodes, number of lymph nodes in the cervical side and postoperative complications between L-type incision and low-position collar incision. There were 7 cases (57.98%) with cervical lymph node metastasis and 27 cases (7.56%) with jumping metastasis. No hoarseness, massive hemorrhage or recurrence occurred. Compared with the traditional "L" incision for functional cervical lymph node dissection, the low neck incision for selective lymph node dissection had a smaller incision (6.5 + 1.40 vs 13.9 + 2.33). Cm, short operation time (172.9 + 41.60 vs 257.3 + 67.59 min), short hospital stay (6.7 + 3.71 vs 7.3 + 1.67 d), low incidence of cervical sensory impairment (1.68% vs 15.38%), high esthetic (6.16% vs 46.15%) and postoperative chylorrhea (1.87% vs 5.13%), symptomatic calcium deficiency (22.67% vs 28.21%) and total number of dissected lymph nodes (15.7 + 7.21%). There was no significant difference in the number of lymph nodes in cervical region (P 0.05). The lymph node metastasis in cervical region was not related to the age of patients (66.18% vs 47.06% vs 45 years old). The lymph node status in area VI (73.17% vs 24.32% without metastasis) was related to the capsule (69.90% vs 53.1%). 5%), primary lesion size (28.57% vs lcmT-4cm group, 59.38% vs T 4cm group, 88.89%), single or multiple lesions (52.0% vs multiple, 68.18%) and lymph node size (75.0% vs 1L < 1.5% vs 69.57% vs < 1 cm group and < 1.1 cm group) with or without calcification or strong echo (67.57% vs without microcalcification or strong echo, 53.66%) and color Doppler ultrasound 35.56% in group A (P 0.05) was associated with gender (60.0% vs 55.93% in males and 55.93% in females) and tumor size (57.69% vs 58.21% on the right side of the left side of the tumor) (P 0.05). The diagnostic criteria consisting of these clinical and pathological features were established, including age 45 years, cervical lymph node diameter (> 1.05 cm) on ultrasonography, multiple primary lesions, lymph node metastasis in area VI, invasion of thyroid capsule. Among the seven clinicopathological features, the cervical lymph node diameter (> 1.05 cm) and the area VI lymph node metastasis were the most influential. The explanatory percentages of the total variance were 27.58% and 19.25% respectively. With the increase of the number of clinicopathological features (from 0 to 7), the rate of lymph node metastasis in the cervical region increased gradually (0.0%, 12.90%, 30.77%, 51.04%, 72.16%, 90.32%, 100.0% and 100.0%). The sensitivity decreased gradually (100.0%, 100.0%, 98.07%, 88.41%, 64.73%, 42.03%, 14.98%, and 0.4%). The specificity increased gradually (0.0%, 2.67%, 20.67%, 50.67%, 82.0%, 96.0%, 100.0% and 100.0%). The Jordan index with four clinicopathological features was the largest (YI = 46.73%). The slope of the four clinicopathological features was the closest to 1 (slope = 1.18863) in the AUC 0.81071.ROC curve. Conclusion If the patient with CN-PTC is 45 years old, the diameter of cervical lymph node is more than 1.05 cm, the primary focus is multifocal, the lymph node in area VI has metastasis, invades the thyroid capsule, the size of primary focus is more than 1.15 cm, and the lymph node has micro-calcification or strong echo. It is safe and feasible to perform PTC selective neck lymph node dissection through low neck incision if neck lymph node dissection is required.
