ABSTRACT
Objective:To explore the safety and feasibility of bilateral axillo-breast approach （BABA） robot in the operation of thyroid cancer in obese women. Methods:The clinical data of 81 obese female patients who underwent da Vinci robotic thyroid cancer surgery（robotic group） at the Department of Thyroid and Breast Surgery, PLA 960 Hospital from May 2018 to December 2021 were retrospectively analyzed and compared with the clinical data of 106 obese female thyroid cancer patients who underwent open surgery（open group） during the same period. The age, body mass index（BMI）, mean time of surgery, mean postoperative drainage, tumor diameter, postoperative tumor stage, number of lymph node dissection in the central and lateral cervical regions, number of positive lymph nodes in the central and lateral cervical regions, postoperative cosmetic outcome satisfaction score, mean postoperative hospital stay and postoperative complications of all patients were counted. The results were analyzed using SPSS 26.0 statistical software, and the count data were compared using the χ² test, and the measurement data were compared using the t test. Results:All patients completed the operation successfully, and there was no conversion in the robot group, postoperative pathological results were all composed of papillary thyroid carcinoma. The operation time in the robot group was（144.62±36.38） min, which was longer than that in the open group（117.06±18.72） min（P<0.05）. The average age of the robot group was（40.25±9.27） years, which was lower than that of the open group（49.59±8.70） years（P<0.05）. The satisfactory score of cosmetic effect in the robot group（9.44±0.65） was higher than that in the open group（5.23±1.07）（P<0.05）. There was no significant difference in tumor diameter, BMI, average postoperative drainage, temporary hypoparathyroidism and recurrent laryngeal nerve injury, number of central and lateral cervical lymph node dissection, number of positive lymph nodes in the central and lateral cervical regions, and average postoperative hospital stay between the two groups. There was no permanent hypoparathyroidism and recurrent laryngeal nerve injury in both groups. Conclusion:The application of BABA pathway robot in thyroid cancer surgery in obese women is safe and feasible, and the cosmetic effect is better after operation.

Objective:To discuss the long-term survival and risk factors of thyroid cancer in the real world in China.Methods:The clinical data of thyroid cancer patients who underwent initial surgery from Apr. 1998 to Dec. 2018 were retrospectively analyzed, including patients’sex, age, surgical records, pathology, hospitalization records and follow-up. According to the prognosis, the patients were divided into disease-free survival group and recurrence/metastasis/death group. Univariate analysis and multivariate regression analysis were conducted to analyze the risk factors affecting the prognosis of thyroid cancer. The clinical features and prognostic risk factors of thyroid cancer patients were investigated.Results:A total of 2038 cases were collected, and the longest follow-up time was more than 20 years. A total of 1876 cases were included in the study, 162 cases were lost, and the rate of follow-up was 7.9%. Among them, 1858 survived, the overall survival rate was 99.04%; 18 died, and the overall mortality rate was 0.96%. According to the prognosis of thyroid cancer, the patients were divided into 2 groups, including 1808 cases in the disease-free survival group and 68 cases in the relapsed-metastatic-death group. The study found that there were statistical differences between the two groups in terms of patients’age [ (45.40±11.016) vs (51.53±15.199, P=0.000) , the male ratio (32.854%, 48.529%, P=0.001) , whether tumor breaks through capsule (20.077%, 33.823%, P=0.006) , central lymph node metastasis (48.834%, 70.588%, P=0.001) and lateral lymph node metastasis (31.084%, 55.882%, P=0.000) , and there was no difference between the number of tumor lesions. Conclusion:Thyroid cancer has a good prognosis, but according to the characteristics of patients with thyroid cancer in my country, it should still be treated early in the clinic, and the standardization and thoroughness of surgery should be adhered to during the treatment.

ABSTRACT
Objective To explore the best operation method in the patients with papillary thyroid microcarcinoma.Methods A total of 139 patients with papillary thjroid microcarcinoma were treated at our institute between Jan.2000 and Jan.2010.The data on the clinicopathological characteristics of patients and treatment were collected.Results The mean tumor size was (0.45 ± 0.24) cm.Of the 139 patients,30.2％ had multifocal tumors,19.4％ had bilateral tumors,42.4％ neck lymph node metastases.The number of eases of lymph node metastasis in level Ⅵ,Ⅱa,Ⅲ and Ⅳ was 58(41.7％),3(2.2％),10(7.9％),5(3.6％),respectively.Only one had lymph node metastasis in Level Ⅲ Microscopic extrathyroid extension was associated with neck lymph node metastases in papillary thyroid microcareinoma patients (x2 =38.39,P ＜0.001).No one developed permanent hypoparathyroidism.The median follow-up time was 103 (range,30-154) months,and local recurrence in the thyoid was diagnosed in 2 patients who underwent hemi-or subtotal thyroidectomy.Follow-up of 10 years was done in 16 cases,and the survival rate of 139 patients for 10-year was 100％.Conclusions It suggested that patients with papillary thyroid microcarcinoma has uniform clinicopathologic characteristics and the pattern of lymph node metastasis from those with papillary thyroid carcinoma.Total thyroidectomy plus level Ⅵ dissection is the optimal surgical treatment of papillary thyroid microcarcinoma.
ABSTRACT
Objective To determine the clinical implications of internal mammary node biopsy for neoplasm stage,treatment,and prognosis in patients with breast cancer.Methods Internal mammary node biopsy via intercostal space was performed in 229 cases of breast cancer.Anatomical location of internal mammary nodes was recorded.Results Internal mammary node biopsy was successfully finished in 220 patients.There were 56 cases (24.45％ ) with internal mammary nodes metastasis,126 cases (55.02％ ) with axillary nodes metastasis,43 cases (34.13％ ) with regional metastases in both the axillary and internal mammary lymph nodes and 13 cases ( 12.62％ ) with internal mammary node metastasis only.Internal mammary node metastasis rate in patients with the number of positive axillary nodes ≥4 was 49.32％ (36/73).pN stage migration was seen in 56 patients with positive internal mammary nodes.There was no statistic relation between internal mammary nodes metastases and tumor location ( x2 =0.661,P =0.719).70.7％ patients with medial/central tumors and 50.7％ patients with the number of positive axillary nodes ≥4 were free from internal mammary node radiotherapy on account of internal mammary node biopsy.There was no complication such as pneumothorax or haemorrhagia.Conclusions Internal mammary node biopsy from intercostal space is a reliable surgical technique and can improve pN stage in some breast cancer patients.With internal mammary node biopsy,patients with a negative internal mammary node can be prevented from radiation to internal mammary nodal areas.
ABSTRACT
ObjectiveTo investigate the changes of serum concentration of parathyroid hormone (PTH) and calcium after thyroid surgery and compare the changes among different modes of operation. MethodsFrom Aug. 2006 to Dec. 2009, 470 patients accepted thyroid surgery. The serum concentration of PTH and calcium in different groups was measured and compared before and 1 day after surgery. According to the extent and similarity of the surgery, patients were classified into 7 groups and they were compared in terms of postoperative changes of PTH and serum calcium. Statistical analysis was performed. ResultsThe serum concentration of PTH and calciurn decreased significantly after surgery in all patients except for those receiving unilateral and bilateral partial thyroidectomy. Compared with unilateral lobectomy, surgeries such as bilateral subtotal thyroidectomy, unilateral thyroidectomy with contralateral subtotal thyroidectomy, bilateral near-total thyroidectomy and total thyroidectomy resulted in more dramatic decreases of serum concentration of PTH and calcium and higher incidence of hypocalcemia ( P ＜ 0.05 ). The comparison between patients receiving CLND or not had the same result. Conclusions Almost all kinds of thyroid surgery affect the parathyroid function. The wider the surgery, the higher the possibility of postoperative hypoparathyroidism. The indications and criteria of different types of thyroid surgery are essential for hypoparathyroidism prevention. In some cases, vitamin D and calcium are recommended for preventive purpose.
ABSTRACT
Objective To compare HER-2 state in breast cancer tissue deteced by fluorescent in situ hybridization (FISH) and immunohistochemistry (IHC) and analyze their correlation. Methods HER-2/neu protein expression and gene amplification were detected by FISH and IHC in 56 newly-diagnosed cases of female breast cancer from July 2008 to July 2009. Results Of the 56 patients, HER-2 protein expression (-), (+), (++), (+++) was 9 cases (16.1%), 29 cases (51.8%), 11 cases (19.6%) and 7cases (12.5%) respectively; 26 cases (46.4%) had HER-2 gene amplification while 30 cases (53.6%) didnt have. Type of HER-2 gene amplification was mainly HER-2(++) and HER-2(+++), and according gene amplification rate was 72 7% and 100%. HER-2 (+) gene amplification rate was 37.9 %(11cases) and no gene amplification was found in HER-2(-) tissue. The HER-2 positive rate using two methods had significant difference(χ2=19.778,P<0.01). HER-2(-) and HER-2(+++) had good consistency with the FISH results(Kappa=0.969),but HER-2(+) and HER-2(+ +) were poorly consistent with the FISH results(Kappa=0.271). Conclusions IHC is the preliminary screening method for detection of HER-2 expression. HER-2(-) and HER-2(+++) have good consistency with the gene amplification, and can guide clinical treatment. Some patients with HER-2(+) and HER-2(++) have HER-2 gene amplification. FISH is needed for targeted therapy.
ABSTRACT
Objective To explore the pattern of cervical nodal metastasis and the clinical significance of total thyroidectomy plus functional neck lymphadenectomy in papillary thyroid carcinoma patients. Methods Clinical and pathological data of 172 patients with papillary thyroid cancer who underwent total thyroidectomy plus functional neck lymph node dissection at Jinan Military General Hospital were retrospectively reviewed, including patient demographics, extent of surgery, parathyroid hormone level,recurrence, tumor pathology, such as tumor size, multifocality, capsular invasion, vascular invasion,extrathyroidal extension, and lymph node status. Results Of the 172 functional neck dissection patients (47 ambilateral), the incidence of lymphonodus metastasis in regions Ⅵ, Ⅳ and Ⅲ was 96. 3% ,78. 5%and 62.1% respectively. Rate of nodal metastasis was higher in patients with extracapsular invasion than in patients with no invasion ( P ＜ 0. 05 ). Serum parathyroid hormone levels significantly decreased immediately postoperatively in total thyroidectomy plus functional neck dissection and remained low for several weeks thereafter ( P ＜ 0. 01 ). The 5-, 10- and 15-year survival rate was ( 98. 83 ± 0. 82) %, (98. 23 ± 1.02 ) % and (96. 42 ± 1.43 )%, respectively. Conclusions Therapeutic neck lymph node dissection for papillary thyroid cancer is recommended for cervical nodal metastasis patients. Total thyroidectomy plus functional neck dissection is important in the treatment of papillary thyroid cancer.
