Significance of selective neck dissection in patients with cN0 thyroid carcinoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To investigate the significance of selective neck dissection in patients with cN0 thyroid carcinoma who have a high-risk of lateral neck lymph node metastasis.</p><p><b>METHODS</b>Sixty three patients with cN0 thyroid carcinoma who have a high-risk of lateral neck lymph node metastasis were prospectively studied at the Department of Head and Neck Surgery, Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between August 2006 and June 2011. The patients with cN0 thyroid carcinoma easy to occur neck lymph node metastasis include: The maximum diameter of primary tumor is ≥ 2 cm; The primary tumor invaded the thyroid capsule; Lymph node metastasis in level VI is found; Lymph node enlargement in level III or/and IV were detected preoperatively by ultrasonography, but not considered as metastasis. The surgical procedure is that the selective neck dissection in level III and IV is performed depending on the collar incision of thyroid surgery. The lymph node chosen from the specimen has a frozen section. If lymph node metastasis is found in the frozen section, a functional neck dissection should be performed through prolonging the collar incision.</p><p><b>RESULTS</b>All cases were pathologically confirmed as thyroid papillary carcinoma. The occult metastasis rate of lateral neck lymph nodes was 39.7%. According to the univariate analysis, the patients with thyroid capsule invasion and lymph node metastasis in level VI were more likely to have lateral neck lymph node metastasis, and the occult metastasis rate was 46.9% and 54.3%, respectively (P = 0.028, P = 0.008), and there were statistically no significant difference in the primary tumor size and the preoperative neck lymph node status by ultrasonography with occult metastasis of lateral neck lymph nodes (P = 0.803 and P = 0.072). According to the multivariate analysis, there was a significant correlation only between the lymph node metastasis in level VI and occult metastasis of lateral neck lymph nodes (P = 0.017), but there was no significant correlation with the thyroid capsule invasion, primary tumor size and neck lymph node status by preoperative ultrasonography in prediction of occult metastasis of lateral neck lymph nodes (all P > 0.05).</p><p><b>CONCLUSIONS</b>Selective neck dissection is feasible for the patients with cN0 thyroid carcinoma who have a high-risk lateral neck lymph node metastasis and the lateral occult metastatic lymph node can be promptly found and removed. We suggest that the selective neck dissection for level III and IV should be routinely performed in cN0 thyroid carcinoma patients with thyroid capsule invasion and lymph node metastasis in level VI.</p>

Minimally invasive endoscopy-assisted neck dissection to treat lateral cervical metastasis of thyroid papillary carcinoma / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>Traditional open surgery for lateral neck dissection for patients with papillary thyroid carcinoma (PTC) leaves an unsightly scar. It is necessary to apply small incision to complete lateral neck dissection with endoscopy-technique for PTC and to evaluate its feasibility and safety.</p><p><b>METHODS</b>Between March 2010 and May 2011, 6 cases of PTC with no definite lymph node metastasis at level II-IV and 12 cases of PTC at T1-T4 with definite lymph node metastasis at level II-V received minimally invasive endoscopy-assisted lateral neck dissection. After accomplishing thyroidectomy and central compartment dissection, ipsilateral level II-IV,VI orII-VI dissection via small neck incision was performed.</p><p><b>RESULTS</b>This procedure was carried out successfully in all 18 patients. The incision was 5 cm every patient. Postoperative pT1 was 5 cases, pT2 5 cases, pT3 6 cases, pT4 2 cases, pN0 5 cases, N1b 13 cases. Mean operative time for lateral neck dissection was 3.6 hours (ranging 2.5-5.0 hours). No significant blood loss or complications occurred. Thirteen patients showed lymph node metastases in both central or lateral neck. The mean number of harvested nodes was 33.1 (ranging 16-61). No residual or recurrent disease was found in 2-3 years follow-up time.</p><p><b>CONCLUSION</b>Minimally invasive video-assisted comprehensive neck dissection for metastatic papillary thyroid carcinoma is feasible and safe with excellent cosmetic results.</p>

Cervical lymph node metastasis in clinical N0 papillary thyroid carcinoma / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To study the patterns of cervical lymph nodes metastasis and the surgical managements of cervical lymph nodes in clinical N0 (cN0) papillary thyroid carcinoma.</p><p><b>METHODS</b>Fifty-one consecutive patients with papillary carcinomas without clinical evidence of cervical lymph node involvement were included in the study between August 2007 and September 2010, in which 53 sides underwent neck lymph node dissection. Preoperative lymphoscintigraphy intra-operative hand-held gamma probe detecting and blue dye technique were used to detect the sentinel lymph node (SLN). SLNs were sent to frozen-section and the results were compared with specimen of routine selective neck dissection. All the pathologic specimens were reviewed by pathologists, counting the numbers of pathologic positive nodes and mapping the localization of positive nodes in level II, III, IV, V and VI respectively. The following criteria were used to study the predictive value of lateral neck compartment lymph node metastasis: age, multifocality of the tumor, extracapsular spread (ECS), tumor size, and the number of central compartment metastasis nodes. Univariate analysis with the χ2 test was used to analyze the statistical correlation between lateral neck compartment lymph node metastasis and the other clinical factors. Multiple logistic regression analysis was used to identify the multivariate correlates of lateral neck compartment metastasis.</p><p><b>RESULTS</b>The occult lymph node metastasis and lateral neck metastasis rates were 77.4% and 58.5% respectively, central compartment metastasis ≥3 nodes was the only independent predictive factor for the metastasis in lateral neck. Twelve sides were pN0 and other 41 sides were pN+ in all 53 side specimens. Of 41 sides with pN+, 17 sides (41.5%) involved single site and 24 sides (58.5%) involved multi-sites. The distribution of metastasis lymph nodes:level VI 62.3%, level III 52.8%, level IV 30.2%, level II 18.9%, and level V 0%.</p><p><b>CONCLUSIONS</b>Cervical occult lymph node metastasis in cN0 papillary thyroid carcinoma mainly localizes in level VI, level III, level IV and level II.Selective neck dissection including level VI, III, IV, II is enough for papillary carcinoma without clinical evidence of cervical lymph node involvement.</p>

Surgical treatment and prognosis analysis on medullary thyroid carcinoma / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To study the clinical characteristics, the surgical treatments and the prognostic factors of medullary thyroid carcinoma.</p><p><b>METHODS</b>Eighty-two cases of medullary thyroid carcinoma undergoing surgeries between January 1999 and December 2004 were reviewed. There were 39 males and 43 females. Age ranged from 16 to 77 years old, with a median of 46 years old. The calcitonin, chromogranin A and neuron-specific enolase were analysed by immunohistochemistry in samples, and calcitonin was detected in 24 cases. Of them, 28 cases underwent lobectomy with isthmectomy, 24 for remained lobe dissection, 16 for total thyroidectomy, and 14 only for neck and upper mediastinal lymph node dissection. Of the 82 cases, 68 cases underwent trachea esophageal ditch dissection, 53 for unilateral neck dissection, 11 for bilateral neck dissection, 13 for upper mediastinal lymph node dissection through trans-cervical approach, and 5 for mediastinal lymph node dissection through inverted T-shaped incision.</p><p><b>RESULTS</b>Immunohistochemical examination revealed that the expression rates of calcitonin, chromogranin A and neuron-specific enolase were 95.8%, 88.9% and 80.0% respectively. Total metastasis rate of neck lymph nodes was 68.8%, and the rates in level II, III, IV, V and VI were 27.3%, 47.7%, 59.1%, 11.4% and 52.3% respectively. The overall five-year survival rate was 87.8%. The recurrent rate of contralateral lobes was 5.8% and local recurrent rate was 7.3% respectively. Univariate analysis showed that gender, age and TNM stage were significant prognostic factors. Multivariate analysis revealed that distant metastasis was an independent prognostic factor.</p><p><b>CONCLUSIONS</b>Standard radical surgery of the primary and metastatic lesion is key to the treatment of medullary thyroid carcinoma. Lobectomy with isthmectomy should be applied to sporadic medullary thyroid carcinoma, with regular postoperative follow-up, and total thyroidectomy to familial or bilateral medullary thyroid carcinoma. Therefore, detecting the calcitonin is very important for medullary thyroid carcinoma patients' prognosis.</p>

<p><b>OBJECTIVE</b>To assess the efficacy and safety of carotid ligation in the treatment of the carotid artery rupture(CAR).</p><p><b>METHODS</b>A series of 30 patients who had CAR treated with carotid ligation were reviewed. There were 24 males and 6 females ranging in age from 32 to 76 years, with a mean of 53.9 years. The original sites of tumours were hypopharynx (n = 11), larynx (n = 5), thyroid (n = 6) and others (n = 8). Of the 30 patients, 24 patients had received radiotherapy from 40 - 126 Gy and 10 patients underwent one or more surgical treatments. CAR in all cases occurred after surgical operation. CAR occurred in 5 - 21 days after operation.</p><p><b>RESULTS</b>By pressing the carotid and keeping breathe of the patients immediately after CAR, 25 patients were conscious, 2 patients in coma, and 3 patients died before carotid ligation. Seven cases were applied with carotid ligation, 3 cases with the combined ligation of carotid and brachiocephalic arteries, and 17 cases with carotid ligation plus the repair by pectoralis major myocutaneous flap. The causes of CAR concluded fistula, wound dehiscence, wound infection and transferred flap necrosis. The mende hemorrhage occurred in 14 patients. Of 25 cases with the treatments of carotid ligation, 22 patients survived with no complication, 1 with brief muscle weakness and 2 with unconscious. Clinical follow-up period lasted more than 5 years at least in 6 patients.</p><p><b>CONCLUSIONS</b>CAR is the most dangerous complication in advanced carcinoma of the head and neck. The prompt hemostasis and carotid ligation are effective methods to rescue patients of CAR. It is important to keep patients conscious before carotid ligation surgery, with low rates of death and hemiplegia postoperatively.</p>

Role of parathyroid hormone measurement in prediction for symptomatic hypocalcaemia after total thyroidectomy / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To evaluate the role of parathyroid hormone (PTH) and serum calcium in prediction for hypocalcaemia after total thyroidectomy.</p><p><b>METHODS</b>One hundred and sixty-five patients undergoing total or complete total thyroidectomy were reviewed retrospectively. The indications included bilateral carcinoma, undifferential carcinoma, surroundings invasion, distant metastasis and huge benign lesions. Preoperative and postoperative PTH, calcium concentrations and their decline levels were compared between Jan. 2005 and May 2009. The role of PTH value and decline level predicting for symptomatic hypocalcaemia were analyzed by receiver operator characteristics (ROC) curve.</p><p><b>RESULTS</b>After total thyroidectomy, 85 patients (51.5%) developed hypocalcemia. Symptoms were reported by 36 patients (21.8%). The mean concentration of PTH for normocalcaemia (80 cases), asymptomatic hypocalcaemia (49 cases) and symptomatic patients (36 cases) were 31.0 ng/L, 19.6 ng/L and 11.9 ng/L, respectively. The mean decline level for the three groups were 28.6%, 52.6% and 78.0%, respectively. PTH value and its decline level had a poor predicting value for symptomatic hypocalcaemia and high negative predicting value for asymptomatic patients. The serum calcium concentration more than 2.0 mmol/L, PTH level higher than 15 ng/L and PTH decline less than 50% had the good negative predicting value of 97.6%, 90.3% and 96.5%, respectively.</p><p><b>CONCLUSIONS</b>Postoperative PTH and its decline level were significantly correlated with postoperative serum calcium concentration but had a low accuracy for predicting symptomatic hypocalcaemia. The serum calcium concentration more than 2.0 mmol/L, PTH level higher than 15 ng/L and PTH decline less than 50% had the good predicting value for asymptomatic patients. Calcium should be routinely supplemented in the first 24 h after total thyroidectomy to reduce the rate of hypocalcemia and the severity of hypocalcemia symptoms.</p>

Sentinel lymph node biopsy in papillary thyroid cancer / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To investigate the reliability and feasibility of sentinel lymph node biopsy (SLNB) of papillary thyroid carcinoma using combination of lymphoscintigraphy, the gamma probe and methylene blue staining techniques.</p><p><b>METHODS</b>Twenty-three consecutive patients with thyroid papillary carcinoma were entered in the study between August 2007 and August 2009. All cases were without clinical evidence of cervical lymph node involvement. The (99)Tc(m)-dextran of 74 MBq (2mCi) was injected intratumorally under ultrasound guidance about 2 h to 5 h prior to surgery. Methylene blue was injected around the tumor during surgery. Preoperative lymphoscintigraphy, intra-operative hand-held gamma probe detecting and methylene blue staining techniques were used to detect the sentinel lymph node (SLN). SLN biopsies were sent to prepare frozen sections and the results were compared with specimen of routine selective neck dissection.</p><p><b>RESULTS</b>The SLNs were identified in all cases with the combination techniques. The SLN identification rates were 87.0% and 100% with methylene blue staining and lymphoscintigraphy plus probe scanning, respectively. Metastases in SLNs were revealed by frozen-section histology in 12 patients. In one case, SLNs frozen-section were negative, but metastasis was detected in routine histology. In other case both SLN and routine histology were negative, but metastasis was detected in non-SLN (level VI) neck dissection. The overall accuracy of the SLN biopsy was 91.3%, positive predictive value 100% and negative predictive value 81.8%.</p><p><b>CONCLUSION</b>The results seem the SLN biopsy technique is a feasible and valuable method for detecting cervical lymph node metastasis and is helpful to decide performing neck dissection in patients with cN0 papillary thyroid carcinoma.</p>

A retrospective analysis of anaplastic thyroid carcinoma / 中国医学科学院学报

<p><b>OBJECTIVE</b>To summarize the new knowledge of the anaplastic thyroid carcinoma (ATC).</p><p><b>METHODS</b>The clinical data of 58 patients (35 men, 23 women, aged 28 to 79 years) with ATC that were treated with various therapeutic modalities from 1981 to 2005 were retrospectively analyzed. Among them, 25 patients received surgery alone (SA group) and 33 received surgery plus radiation (S + R group). The dosage of postoperative radiotherapy was 40-70 Gy. Four patients received biopsy, 24 received palliative surgery, and 30 received radical surgery. Only 2 patients received complete chemotherapy.</p><p><b>RESULTS</b>ATC invaded trachea in 40 patients (69.0%), esophagus in 32 patients (55.2%), and carotid in 17 patients (29.3%). The cervical lymph node metastases occurred in 19 patients (32.8%). The overall 1-year survival rate was 37.8%, 3-year survival rate 31.2%, and 5-year survival rate 25.9%. The 5-year survival rate was 37.8% in S + R group but was only 9.9% in SA group (P = 0.0000). The 5-year survival rate was 41.4% in radical surgery subgroup but was only 12.4% in palliative surgery subgroup (P = 0.0023). In < or = 45-year-old subgroup (n = 4), the 5-year survival rate was 50.0%; however, in > 45-year-old subgroup, it was only 21.3%. In postoperative radiation < 60 Gy subgroup , the 5-year survival rate was 19.3%; however, in > or = 60 Gy group, it was 53.7% (P = 0.0000). Among all the 58 patients, some patients received palliative surgery because of tumor invasion in trachea (n = 16, 27.6%), esophagus (n = 8, 13.8%), carotid (n = 8, 13.8%), and other sites (n = 13, 22.4%). Twenty-four patients (61.5%) died of localrelapse, 2 (5.1%) of cervical lymphnode failure, 9 (23.1%) of metastasis, and 4 (10.3%) of other reasons.</p><p><b>CONCLUSIONS</b>The prognosis of ATC is poor. Radical surgery and postoperative radiation > or = 60 Gy can improve the survival rate. Tumor invasion in trachea, esophagus, and carotid are the main reasons of palliative surgery. Local relapse is lethal.</p>

Surgical therapy of subglottic carcinoma / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To analyze the clinical characteristics, surgical procedures and correlated prognostic factors of the cases with subglottic carcinoma; to seek for the optimal surgical treatment for the patients suffering from subglottic carcinoma.</p><p><b>METHODS</b>Twenty-four cases with subglottic carcinoma were retrospectively reviewed, the disease-free survival rates of the patients at 3 years were analyzed according to the different T N phases and the surgical modalities.</p><p><b>RESULTS</b>The free-disease survival rate at 3 years was 50.0% (12/24) for 24 cases with subglottic carcinoma. The survival rates of 19 cases with total laryngectomy was 47.4% (9/19), and the survival rates in T2, T3, T4 phases were respectively 1/1, 6/11, 2/7. The survival rates of 5 cases with partial laryngectomy was 3/5, the survival rates in T2, T3 phases were respectively 3/4, 0/1, and the surgical margins were verified to be positive in 2 of 5 cases being performed partial laryngectomy. The metastasis rate of lymph nodes was 33.3% (8/24). The survival rates of patients with N0, N1, N2 disease were respectively 10/16, 1/4, 1/4. The positive lymph nodes were verified in the neck regions of II-VI and superior mediastinum.</p><p><b>CONCLUSIONS</b>Prognoses of the cases with subglottic carcinoma were poor, early treatment could result in good effect. Until now total laryngectomy still the mainly treatment of subglottic carcinoma. Only the patients with earlier subglottic carcinoma are amenable to partial laryngectomy and should be given postoperative irradiation. Lymph node metastasis was a very important prognostic factor. Paratracheal lymph nodes are the sentinel nodes for subglottic carcinoma, and it is reasonable to probe the nodes. Once verifying positive lymph node, the typical neck dissection involving I-VI regions and superior mediastinum should be performed.</p>
