ABSTRACT

Objective:To study the risk factors of postoperative permanent hypoparathyroidism after total thyroidectomy.Methods:In this retrospective study ,the receiver operating characteristic (ROC) curve of postoperative 24 h parathyroid hormone(PTH) values was used to predict the risk of permanent hypoparathyroidism.The clinical and pathological features that related to postoperative permanent hypoparathyroidism were studied by χ2 test and multivariate Logistic regression analysis. Results:Eight hundred and eighty-nine patients were enrolled, the incidence of postoperative transient and permanent hypoparathyroidism was 33.3% and 4.0%, respectively. When 24 h PTH levels less than or equal to 5.84 pg/ml were used as cut off value, the sensitivity of the prediction of permanent hypoparathyroidism was 100%, the specificity was 72%, and the positive predictive value was 22.5%. The presence of parathyroid gland in the pathologic specimen, parathyroid autotransplantation and PTH≤5.84 pg/ml at 24 h after operation were statistically significant risk factor for permanent hypoparathyroidism in multivariate analysis( χ2=10.900, P=0.001; χ2=4.415, P=0.044; χ2=13.576, P=0.000). Group analysis found that the lower 24 h PTH the higher incidence of permanent hypoparathyroidism. Conclusions:For patients undergoing total thyroidectomy, when parathyroid gland is involved and/or the PTH value is low at 24 h after surgery, the occurrence of permanent hypoparathyroidism is high.

ABSTRACT

Nasopharyngeal carcinoma (NPC) is a common head and neck malignant tumor with high incidence in southern China. Local recurrence is one of the main failure modes of locally advanced NPC. The dose-escalation after radical radiotherapy for locally advanced NPC remains controversial. In the era of modern radiotherapy, the mainstream treatment mode of locally advanced NPC is neoadjuvant chemotherapy plus concurrent chemoradiotherapy. There is no consensus on whether to prescribe dose-escalation, how and when to conduct dose-escalation, how much dose to prescribe for patients with residual lesion proved by MRI or pathology. How to accurately determine the target volume and dose / fraction to maximize the local control of the tumor are the directions of clinical practice for locally advanced NPC, which remain to be further studied.

ABSTRACT

Objective:To investigate the patterns of lateral and central neck lymph node metastasis in N1b papillary thyroid carcinoma (PTC) patients.Methods:From Jun 2018 to Sep 2020, 96 consecutive treatment-naive unilateral N1b PTC patients were included. After total thyroidectomy, bilateral central neck and unilateral lateral neck dissection (including the level Ⅱa, Ⅱb, Ⅲ, Ⅳ and Ⅴb) metastasis in different levels and pathological status of lymph nodes were analyzed.Results:The lymph node metastasis rates were 85% in ipsilateral paratracheal region, 82% in level Ⅲ, 77% in level Ⅳ, 55% in pre-tracheal region, 47% in contralateral paratracheal region, 40% in level Ⅱa, 34% in pre-laryngeal region, 6% in level Ⅱb, 6% in intermuscular region, 4% in level Ⅴb. Tumor size >1cm and pre-tracheal lymph nodes netastasis were associated with contralateral paratracheal metastasis ( OR=3.282 and 3.064, P<0.05); Metastasis to Ⅵa was associated with metastasis to Ⅵb ( OR=3.364, P<0.05). Conclusion:Level Ⅱa-Ⅳ of lateral neck and all subgroups of central neck lymph nodes tend to be involved in PTC with lateral neck metastasis. Lateral neck including level Ⅱa-Ⅳ and the whole central neck including right Ⅵb lymph nodes dissection is recommended for N1b PTC patients.

ABSTRACT

Objective@#To investigate the diagnostic performance of fine-needle aspiration (FNA) cytology for the detection of lateral lymph node metastases in patients with papillary thyroid carcinoma (PTC).@*Methods@#A total of 109 lateral lymph nodes with suspicious metastases from 85 patients were retrospectively subjected to FNAC, fine-needle aspiration thyroglobulin measurement (FNATg), and FNATg/SerumTg measurement. Lymph node pathological results after surgery were taken as the gold standard. Using Mann-Whitney U test, Pearson linear model and ROC curve were used for data analysis.@*Results@#The sensitivity, specificity and accuracy of FNATg for the diagnosis of lateral neck lymph node metastasis were respectively 93.7%, 90.0% and 93.3% and those of FNATg/SerumTg were respectively 89.9%, 90.0% and 93.2% respectively, the threshold values for FNATg and FNATg/SerumTg were 0.925 ng/ml and 1.007, respectively. The sensitivity, specificity and accuracy of FNATg combined with FNAC were respectively 91.0%,93.5% and 94.4%. The existence of thyroid tissue and the expression of serum Tg did not affect the expression of lymph node FNATg. The FNATg cutoff value of 0.925 ng/ml showed the best diagnostic performance in patients with a thyroid gland, while the FNATg/SerumTg cutoff ratio of 14.95 showed the best diagnostic performance in patients without a thyroid gland. The serum TgAb significantly interfered with the expression of FNATg in the lateral neck metastatic lymph nodes (P=0.049).@*Conclusions@#FNATg alone or the combination of FNATg with FNAC are highly reliable in the diagnosis of lateral neck lymph node metastases in patients with PTC. The expression of TgAb may interfere with the accuracy of the diagnostic performance of FNATg.

ABSTRACT

Objective@#To study the diagnostic value of a multi-gene molecular testing in cytologically indeterminate thyroid nodules.@*Methods@#From February 2018 to September 2018, patients with thyroid nodules who underwent fine needle aspiration(FNA) at Peking University Cancer Hospital were enrolled. Three hundred and sixty patients were included, consisting of 86 men and 274 women, with a mean age of 45.8 years (between 13 and 89 years old). Among 391 nodules, 141 were cytologically inderminate and 75 were resected. FNA samples underwent prospective testing using a next-generation sequencing (NGS) assay, which included 16 genes for point mutations and 26 types of gene fusions. The testing results of indeterminate nodules were compared with surgical outcomes, to determine the diagnostic performance. The results were compared with the BRAF V600E single gene mutation analysis by χ2 test.@*Results@#The multi-gene testing showed a sensitivity of 73.2%, specificity of 96.8%, positive predictive value of 96.8%, and negative predictive value of 73.2%. The diagnostic accuracy of multi-gene testing was significantly higher than the BRAF V600E mutation test (83.3% vs 73.6%, χ2=31.588, P<0.01).@*Conclusion@#Multi-gene testing in FNA samples is an effective method to diagnose cytologically indeterminate thyroid nodules, which has a higher accuracy than BRAF V600E mutation detection.

ABSTRACT

Objective To compare the efficacy and side-effects of preoperative neoadjuvant uterine arterial chemoembolization and venous chemotherapy in treating cervical cancer in young female patients. Methods A total of 241 young females(≤35 years old) with cervical cancer were enrolled in this study. The clinical data were retrospectively analyzed. The patients were divided into group A (n=63) and group B (n=57). Patients in group A received preoperative neoadjuvant uterine arterial chemoembolization with subsequent surgery, while patients in group B were treated with preoperative neoadjuvant intravenous chemotherapy followed by surgery. The chemotherapy scheme included carboplatin (50 mg/m2) and gemcitabine (1 000 mg/m2). The short-term effect, the amount of blood loss during the surgery, pathological findings and the side-effects of the two groups were compared. The Kaplan-Meier method was used to calculate survival rate, and the log-rank test was used for survival difference analysis. Results The short-term response rate of group A was 90.5%, which was significantly higher than that of group B (71.9%), the difference between the two groups was statistically significant (χ2=7.5, P0.05). In both groups, the clinical stage, the pathological grade and the size (≥ 4 cm) of the tumor were the main factors that could influence the prognosis in young females with cervical cancer (P<0.05). Conclusion The short-term efficacy of preoperative uterine artery chemoembolization is better than that of preoperative intravenous chemotherapy for the treatment of cervical cancer in young female patients. Besides, this therapy carries mild side effect, and it can improve the 5-year progression-free survival rate, although the long-term survival rate has not been obviously improved.

ABSTRACT

In order to investigate the features of multidetector CT (MDCT) and magnetic resonance imaging (MRI) as well as the corresponding pathogic basis of solitary fibrous tumor (SFT) in the pelvis, we collected the clinical data of 13 patients with pathologically confirmed SFT in pelvis, and retrospectively reviewed the MDCT and MRI appearances. Of these enrolled patients, 6 received MDCT scans, 5 underwent MRI scans, and 2 underwent both MDCT and MRI examinations. Shown on the MDCT and MRI, the maximum diameters of the masses ranged from 4.0 to 25.2 cm (averaged 11.8 cm). Six masses were lobulated, and seven were round or oval. In addition, all masses were well-defined and displaced the adjacent structures to some degrees. On the computed tomography, all masses were of isodensity on unenhanced scans in general, among which five masses were demonstrated with hypodense areas. On the MRI T1-weighted image, all lesions were isointense, of which patchy hypointense areas were detected in 3 cases and radial hypointense areas were in 3 cases, and the other one was presented with homogenous intensity. On T2-weighted images, most of the lesions were mixed hyperintense, of which 3 cases were of heterogenous hyperintesity, radial hypointense areas were detected in 3 patients, and the other one was homogenously intense. On enhanced computed tomography and MRI, large supplying vessels were found in 4 cases; 12 cases showed moderate to conspicuous enhancement, and the other one was presented with mild homogenous enhancement. Of the patients with moderate to conspicuous enhancement, patchy areas of non-enhancement were detected in 7 cases, radial areas of progressive enhancement were detected in 3 cases, and the remained 2 cases showed homogenous enhancement. On pathology, the radial area presented as progressive enhancement was fibrosis. During the follow-ups after surgery, 2 patients had local recurrence and 1 had metastasis to liver. In conclusion, the SFT in the pelvis are commonly presented as a large solid, well-defined and hypervascular mass with necrosis or cystic changes at some extents together with the displacement of adjacent structures. The radial area with hypointensity on T2-weighted image and with progressive enhancement on enhanced magnetic resonance imaging is an important feature of SFT, which can be helpful for the diagnosis of this mass.

Objective To investigate the efficacy of uterine artery chemoembolization in the treatment of locally advanced cervical cancer.Methods A total of 268 patients with locally advanced cervical cancer were treated with uterine artery chemoembolization in our department.The stage distribution among the patients included 132 stage Ⅰ B2,85 stage Ⅱ A1 and 51 stage Ⅱ A2.There were 223 patients of squamous cell carcinoma,24 patients of adenocarcinoma,9 patients of adenosquamous carcinoma,small cell carcinoma of the 7 patients,5 patients of neuroendocrine carcinoma.Transcatheter uterine artery infusion of paclitaxel and nedaplatin,gelatin sponge particles was applied for uterine artery embolization.The clinicopathological parameters were analyzed,and their impacts on tumor response were investigated.RECIST criteria were used to evaluate the response in solid tumors.Student t test was used to compare cervical tumor diameter before and after treatment,and Chi-square test was used for comparison of categorical data.Follow up examinations included pelvic ultrasound,gynecology,vaginal stump cell smears.Results Of the 268 patients,74 (27.6%) patients showed a complete response,160 (59.7%) patients had a partial response to uterine artery chemoembolization,and the overall response rate was 87.3%.A total of 258 (96.3 %) patients underwent surgery,and pathological complete response were identified in 46 (17.2%).Forty (14.9%) patients were found to have lymph node metastasis after surgery.Response rates of stage Ⅰ B2 and Ⅱ A cases were 94.7% and 80.1%,respectively,P < 0.05.Patients with squamous cell carcinoma showed a better response rate than patents with other pathological types (94.2% vs.53.3%),P < 0.05.Initial tumor volume and cycles of preoperative uterine artery chemoembolization had no effect onthe response rate.Conclusions Uterine artery chemoembolization can increase the rate of surgical resectionof patients with locally advanced cervical cancer and can improve the reaction rate with tolerable side effect.It is an applicable option of treatment for patients with locally advanced cervical cancer in the neoadjuvanttreatment.
