Objective To summarize the characteristics of lymph node metastasis in patients with papillary thyroid carcinoma accompanied with Graves disease,and to provide evidence for clinical treatment. Methods Totally 98 patients with papillary thyroid carcinoma and Graves disease who had been treated in Peking Union Medical College Hospital from January 2004 to December 2013 were divided into the lymph node metastasis positive group (n=34) and lymph node metastasis negative group (n=64). The general information,blood biochemical results,pathological results,and prognoses were compared between these two groups. Results These two groups showed no significant differences in gender (χ=0.2113,P=0.6458),age (t=1.7000,P=0.0922),tumor diameter (t=1.2559,P=0.2122),and multifocal tumors (χ=1.9170,P=0.1661). The median level of thyrotropin receptor antibody (TR-Ab) value in the lymph node metastasis positive group was 4.84 U/L,which was significantly higher than that in the negative group which was 2.99 U/L (t=2.0169,P=0.0465). There were no significant differences in serum thyroid stimulating hormone (t=0.0257,P=0.9800),free triiodothyronine (t=1.3610,P=0.1770),free thyroxine (t=0.0082,P=0.9930),thyroid peroxidase antibody (t=0.0177,P=0.9860),and thyroglobulin antibody levels (t=1.1450,P=0.2550) between two groups. The postoperative pathological results showed that tumor capsular invasion rate (26.5% vs. 9.38%;χ=5.006,P=0.0253) and lymph node recurrence rate (14.7% vs. 1.56%;χ=4.583,P=0.0323) were significantly higher in the positive group than in the negative group. The distal metastasis rate in the positive group and negative group were 5.88% and 0,respectively. Conclusions There is no definite association between lymph node metastasis and tumor size in patients with thyroid papillary carcinoma associated with Graves disease. The risk factors for lymph node metastasis include TR-Ab and tumor capsular invasion,with a higher incidence of lymph nodes recurrence.

<p><b>BACKGROUND</b>Familial nonmedullary thyroid carcinoma (FNMTC) is a variant of nonmedullary thyroid carcinoma(NMTC) with particular clinicopathologic features. In recent years, a number of studies have shown that FNMTC is more invasive than sporadic NMTC(SNMTC). The purpose of this study was to explore the differences in clinicopathologic features of FNMTC between different types of families and to determine in which of these families more invasive FNMTC occurred.</p><p><b>METHODS</b>We retrospectively reviewed all patients with thyroid carcinoma admitted to Peking Union Medical College Hospital from January 2009 to July 2013 in the database. Of all 2000 cases, 55 met the inclusive criteria for FNMTC and were studied. There are two different grouping methods. The first is that all samples were allocated to families with three or more first-degree relatives affected (FNMTC-3 group) and families with only two affected first-degree relatives (FNMTC-2 group). The second is that all patients were divided into families with three or more affected first-degree relatives over two generations (FNMTC-3-2 group) and the other families. We compared the clinicopathologic features such as sex, age, tumor size, multifocality, location, complications by thyroiditis, complications by benign thyroid nodules, surgical procedure, capsule invasion, histological type, lymph node metastases, tumor node metastasis stage, and BRAF mutation between FNMTC-2 group and FNMTC-3 group. We also made the same comparison between FNMTC-3-2 group and other families.</p><p><b>RESULTS</b>No pronounced differences in clinicopathological features were present between FNMTC-2 group and FNMTC-3 group. The proportion of FNMTC-3-2 group aged <45 years was significantly higher than that in the other families (58.8% vs. 26.3%, P = 0.021). A similar difference was found in the proportion of lymph node metastasis (64.7% vs. 34.2%, P = 0.035).</p><p><b>CONCLUSIONS</b>FNMTC-3-2 is more invasive than the other families. Early screening and positive treatment for members of these families are recommended.</p>

<p><b>OBJECTIVE</b>To report the management experiences of of gastric small cell carcinoma.</p><p><b>METHODS</b>The clinicopathological data of 6 cases of gastric small cell carcinoma treated from 1997 to 2007 were retrospectively reviewed. And meanwhile review the relevant literature.</p><p><b>RESULTS</b>All the 6 cases were male with an average age of 56.5 years (range, 40-66 years). All the patients received surgery and 4 of them received postoperative adjuvant chemotherapy. Two cases were followed up, one lived without recurrence for 4 years all along, the other one died of recurrence and extensive metastasis 9 months after operation. In the literature, 164 male and 59 female patients have been reported to date, with an average age of 64.2 yrs (range, 42-84 years). Tumor located in the fundus in 97 cases, 55 in gastric body,54 in gastric antrum. In gross, 137 cases were classified as ulcerative type, 47 were protruded type. The average tumor diameter was 6.23 cm (range, 0.8-17.0 cm). Among 223 cases, only 43 survived more than 1 year.</p><p><b>CONCLUSIONS</b>It is difficult to make a definite diagnosis before or during the operation for gastric small cell carcinoma. The radical operation could be done according to other gastric cancer and the lymph node dissection could be simplified. Postoperative chemotherapy with the same scheme as lung small cell carcinoma may help improving the outcome.</p>

<p><b>OBJECTIVE</b>To investigate the indication, operative method and results of selective neck dissection (SND) for differentiated thyroid cancer.</p><p><b>METHODS</b>According to the level system and the operative guideline of the American Head and Neck Society, 40 cases of thyroid cancer (phase I: 35 cases, phase II: 2 cases, phase III: 3 cases) were collected prospectively. Thyroidectomy plus SND was performed on all the cases. And the indication, operative methods and results were investigated.</p><p><b>RESULTS</b>Nine of the 40 cases received level VI dissection only. Twenty-four of the 40 cases received SND with levels </= 3 by a simple transverse incision on the neck. The overall lymph nodes positive rate was 67% (28/42). The positive rates of VI, IV, III, II and V levels were 58% (23/40), 48% (16/33), 48% (14/29), 50% (7/14) and 27% (4/15) respectively. The positive rate of level VI was not significantly higher than those of the level IV, III and II (P > 0.05). One parathyroid was found in 20% (8/40) of the specimen and 27% (11/40) of the patients had transient hypocalcemia, but no permanent hypocalcemia. Three (7.5%) of the patients had vocal cord paralysis for a short period of time and no permanent case was detected. Nineteen patients were followed up for more than 6 months after the operation and no enlarged neck lymph node was found by ultrasound at the 6th month postoperatively.</p><p><b>CONCLUSION</b>It is reasonable to give SND to the early thyroid cancer patients.</p>

<p><b>OBJECTIVE</b>To explore the principles of diagnosis and treatment of chronic lymphocytic thyroiditis (CLT) coexistent with thyroid malignancy.</p><p><b>METHODS</b>The clinical data of 52 patients with CLT, including clinicopathologic features, treatment, and prognosis were retrospectively analyzed. Among these 52 patients, 40 patients had coexisting thyroid carcinoma (TC group) and 12 had coexisting thyroid lymphoma (TL group).</p><p><b>RESULTS</b>These two thyroid malignancies accounted for 13.87% of all the CLT inpatients during this period, in which 10.67% were CLT with carcinoma and 3.20% were CLT with lymphoma. Significant differences existed between TC group and TL group in sex (P = 0.008) , age (P = 0.000), and B-mode ultrasound findings (P = 0.000). Most patients in TC group received total lobectomy of one lobe and subtotal lobectomy of the other side, of which some received elective lymphadenectomy. The operations varied among patients in TL group, and most of them received chemotherapy after surgery. The median follow-up was (35.51 +/- 39.84) months for 37 patients in TC group, and 36 patients survived with a median period of (34.50 +/- 39.91) months; the median follow-up was (39.50 +/- 29.00) months for 12 patients in TL group, and 10 patients survived with a median period of (44.70 +/- 28.78) months.</p><p><b>CONCLUSIONS</b>CLT with thyroid malignancies are not uncommon in clinical practice. While thyroid carcinoma accounts for majority of these malignancies, its clinicopathologic features, treatment, and prognosis differs with thyroid lymphoma. Surgery may be appropriate for CLT patients with rapid thyroid enlargement or nodule, and for patients with solitary solid nodule or nodules with calcification revealed by B ultrasound.</p>

<p><b>OBJECTIVE</b>To compare the advantages and shortcomings of the endoscopic thyroid surgery by trans-subclavian approach and trans-areolar approach.</p><p><b>METHODS</b>Twelve patients received the trans-areolar approach and 10 patients were given the trans-subclavian approach procedure.</p><p><b>RESULTS</b>With the trans-areolar approach: the mean size of tumor was 1.8 cm, the mean operating time was 115 min, the mean blood loss during operation was 63 ml. Two patients converted to the conventional operation. With the trans-subclavian procedure: the mean size of tumor was 4.2 cm, the mean operating time was 85 min, the mean blood loss during operation was 66 ml. No complications were found in all of the patients and they were satisfied with the cosmetic effects of the procedures. There were significant differences in tumor size and operating time between the two operation types.</p><p><b>CONCLUSIONS</b>Compared with the trans-areolar approach, the trans-subclavian approach comes with less trauma, higher success rate and it fits for bigger tumor.</p>
