ABSTRACT
Objective:To evaluate the feasibility of the gasless transoral endoscopic thyroidectomy using an innovative space maintaining method.Methods:From Dec. 2018 to Apr. 2019, patients from Anhui Tumor Hospital treated with gasless transoral endoscopic thyroidectomy were retrospectively analyzed. Index such as intraoperative blood loss, operative time, postoperative hospital stay, and complications were recorded.Results:A total of 24 patients were included into this analysis. All operations were successfully completed. The mean blood loss was (41.3±26.4) ml, operation time was (191.8±40.8) min, postoperative hospital stay was (6.3±1.0) d. Nobody had drinking cough, recurrent laryngeal nerve palsy, massive bleeding, hypoparathyroidism or infection with use of preventive antibacteria. Transient lower jaw numbness was found in 8 patients and almost recovered within one month.Conclusions:Gasless transoral endoscopic thyroidectomy with the suspension device seems to be feasible and safe. Further study is needed to verify its validity.
ABSTRACT
Objective To investigate the clinical significance of the carbon nanoparticles (CN) in prophylactic central compartment lymph node dissection (PCCND) in treatment of clinically node-negative (cN0) papillary thyroid carcinoma.Methods A total of 102 cN0 patients in our department from Dec.2016 to Jun.2017 were enrolled in our study and randomly allocated to the control group (n=51) and the CN group (n=51).All the patients have received (near) total unilateral lobectomy or bilateral thyroidectomy plus the affected side PCCND.The baseline characteristics,lymph node-related indices (including number of total dissected lymph nodes and metastatic lymph nodes at central area) and postoperative complication indices were collected and compared between the 2 groups.Results The differences of baseline characteristics between CN group and the control group were not significant (all P＞0.05).The total number of dissected lymph nodes was 573 in CN group and 334 in the control group.The average lymph nodes in each patient was 11.2±5.46 in CN group,which was higher than 6.5±4.3 of the control group (P＜0.001).The average count of positive lymph nodes was higher in CN group than in the control group (2.0±3.3 vs 0.8±1.5) (P＜0.05).Transient hypocalcaemia happened to 2 patients in CN group and 9 patients in the control group (P=0.025).Conclusions CN can increase the number of lymph nodes in central neck dissection and the rate of metastatic lymph nodes resection.It can decrease the risk of transient parathyroid injury.CN is clinically valuable in treatment of cN0 papillary thyroid cancer undergoing PCCND.
ABSTRACT
Objective To explore the operative indication , therapeutic effects and feasibility of immedi-ate mammoplasty with lateral thoracic steato-fascia flap.Methods A retrospective study was carried out on clini-copathologic data of 26 patients receiving nipple-areola complex preserving modified radical mastectomy and im-mediate mammoplasty with lateral thoracic wall adipofascial flap and 5 patients receiving segmental mastectomy and immediate mammoplasty with lateral thoracic wall adipofascial flap because of benign breast diseases .In these patients receiving nipple-areola complex preserving modified radical mastectomy , 22 patients received lateral tho-racic wall adipofascial flap , and 4 patients received lateral thoracic wall adipofascial flap combined with silicone prosthesis .The surgical complications and cosmetic effects were evaluated by both subjective and objective stand -ard postoperatively .Results 24 patients were satisfied with the appearance of their breasts and the two sides seemed to be symmetrical .There was no flap or nipple necrosis .The patients received adjuvant chemotherapy after surgery.No local recurrence or distant metastasis occurred during the follow up (2 to 12 months).Five patients with benign breast diseases were very satisfied with their breast appearance after surgery .Conclusion For patients in early stage breast cancer receiving modified radical mastectomy with nipple-areolar complex preserved and patients with benign breast diseases having segmental mastectomy , immediate mammoplasty with lateral thoracic wall adipo-fascial flap is a good method which can help to keep well breast apperance without additional incision , and it is also economical , feasible , and can reduce patients'psychological pressure due to loss of the breast .
ABSTRACT
Objective To investigate the expression of breast cancer specific gene 1( BCSG1) in breast cancer tissues and its clinical significance.Methods The expression of BCSG1in 51cases of breast cancer tissues and 35 cases of adjacent tissues was determined by fluorescence quantitative polymerase chain reaction (FQ-PCR) and immunohistochenistry.Results FQ-PCR showed the expression level of BCSG1mRNA in breast cancer and adjacent tissues was 1.072 ± 0.178 and 0.324± 0.135 respectively.Immunohistochemistry showed the expression rate of BCSG1protein in breast cancer and adjacent tissues was 74.5％ (38/51) and 14.3％ (5/35).The expression of BCSG1mRNA and protein was dramatically increased in breast cancer tissues compared with that in normal background breast tissues (P ＜ 0.05).BCSG1mRNA and protein expression was significantly different in patients with lymph node metastasis and higher Nottingham prognostic index (P ＜ 0.05 ),and there was no significant difference with the pathological type of breast cancer,or status of ER,PR,and c-erbB2 ( P ＞ 0.05 ).Conclusions BCSG1is highly expressed in breast cancer tissues,which is closely related to the development and clinical prognosis of breast cancer.BCSG1is very likely to play an important role in the pathogenesis of breast cancer.
ABSTRACT
For breast cancer among youth, overtreatment should be avoided to reduce toxic effects on reproductive function while maintaining acceptable therapeutic effect on cancer. Research has indicated that breast cancer can have a relatively small treatment-related threat to fertility among youth patients if the timing of pregnancy after breast cancer is optimized. Pregnancy and childbirth have not been associated with recurrence and survival among early stage breast cancer.
