ABSTRACT

As a treatment option for cancer, thermal ablation has satisfactory effects on many types of solid tumors (such as liver and renal cancers). However, its clinical applications for the treatment of thyroid nodules and metastatic cervical lymph nodes are still under debate both in China and abroad. In 2015, the “Zhejiang Expert consensus on thermal ablation for thyroid benign nodules, microcarcinoma, and metastatic cervical lymph nodes (2015 edition),” was released by the Thyroid Cancer Committee of Zhejiang Anti-Cancer Association, China. To further standardize the application of thermal ablation for thyroid tumors, the Thyroid Tumor Ablation Experts Group of Chinese Medical Doctor Association has organized many seminars and finally produced a consensus to formulate the “Expert consensus workshop report: Guidelines for thermal ablation of thyroid tumors (2019 edition).”

ABSTRACT

Objective@#RET/PTC gene rearrangement can lead to aberrant activation of tyrosine kinase receptors, which is a common mutation in papillary thyroid carcinoma (PTC). This study focuses on the association of RET/PTC rearrangements with PTC clinical factors.@*Methods@#From January 2011 to December 2013, a total of 114 patients with PTC were enrolled in this study. Clinicopathological parameters, lifestyle, and thyroid hormone levels were collected. RET/PTC rearrangements were detected by TaqMan PCR and verified by Sanger sequencing.Data were analyzed with SPSS software, including chi-square test, Fisher′s exact test, Mann-Whitney U test, Student′s t-test, and Logistic regression.@*Results@#RET/PTC rearrangements were not found in all paracancerous normal thyroid tissues, and were detected in 23.68% (27/114) of PTC. Further analysis revealed no correlation between RET/PTC rearrangement and thyroid function, clinicopathologic parameters, and lifestyle in the total PTC group or in the subgroup of patients with concomitant diseases (including Hashimoto′s thyroiditis and nodular goiter). But in the subgroup of PTC without concomitant disease, RET/PTC rearrangement was associated with tumor multifocal (P=0.018), and RET/PTC-positive PTC patients had an increased risk of tumor multifocal (OR=5.57, 95% CI 1.39-22.33). It was also found that RET/PTC rearrangement was associated with an abnormal increase in TSH level of one month after surgery (P= 0.037).@*Conclusion@#Nodular goiter and Hashimoto ′s thyroiditis may be a confounding factor in PTC. RET/PTC rearrangement may play an important role in the occurrence of thyroid carcinoma multifocal after exclusion of this confounding factor.

ABSTRACT

OBJECTIVE@#To evaluate the treatment and prognosis of sinonasal mucosal melanoma (SMM).@*METHOD@#Clinicopathological data of SMM patients from January 1976 to December 2005 were analyzed retrospectively. Survival analysis was performed and Kaplan-Meier analysis was used to compare the effect of clinicopathological factors on survival using SPSS 18.0 software. A Cox model was applied for multivariate analysis.@*RESULT@#The 3-year and 5-year overall survival (OS) rates of 68 cases of SMM were 36.1% and 29.4%, respectively. The 3-year and 5-year OS of patients who underwent surgery or biotherapy were significantly higher than that of patients who underwent other therapeutic regimens without surgery or without biotherapy, respectively. Multivariate analysis showed the patients with distant metastasis at first present or residual/recurrence had a worse prognosis than that without distant metastasis or residual/recurrence, respectively. Surgery and biotherapy were effective treatments for SMM.@*CONCLUSION@#SMM has a poor prognosis, especially in the patients with distant metastasis or residual/recurrence. Surgery or biotherapy may improve the prognosis of patients with SMM.

ABSTRACT

ObjectiveTo evaluate the clinical value of infrahyoid myocutaneous flap in the reconstruction of mouth floor tissue defects. MethodsInfrahyoid myocutaneous flap was made including stenohyoid,thyrohyoid,omohyoid and the affiliated skin based on the axis of superior thyroid artery,vein and ansa cervicalis. The clinical data of 11 patients with reconstruction of mouth floor tissue defects using infrahyoid myocutaneous flap (maximum area was 8 cm × 3 cm) from Match 1993 to June 2009 were retrospectively reviewed.ResultsSeven infrahyoid myocutaneous flaps which reserved platysma branch of superior thyroid artery were all alive, while 2 patients presented epidermal necrosis of 4 un-protected patients. The follow-up period was range from 24 months to 195 months, one patient received salvage surgery for local regional lymphatic recurrence in level Ⅰ,which survived without diseases until now.The rest cases had turned out a success.No dysphagia,dysphonia,and tongue extension difficulty was reported in any patient.ConclusionInfrahyoid myocutaneous flap is one of the valuable donor sites for the reconstruction of mouth floor tissue defects after radical oncologic operations,especially for those with early stage carcinoma of the mouth floor.

ABSTRACT

Objective To evaluate the clinical characters, management and prognostic factors of patients with differentiated invasive thyroid carcinoma (DITC). Methods The data were analyzed retrospectively for 114 DITC patients treated at Department of Head and Neck Surgery of Sun Yat-sen University Cancer Center. Survival analysis was performed by Kaplan-Meier method, comparison among/between groups was performed using log-rank test, and multivariate analysis was carried out using Cox proportional hazard model. Results After surgery, 68 patients were with tumor residue. The 5-year and 10-year overall survival rate were 91.9% and 80.1% respectively in all patients, while the 10-year overall survival rate were 88.5% 、78.5% and 53.1% in no tumor residue group, micro-residue group and grossresidue group respectively. This study failed to prove that radiotherapy might improve the survival rate in patients with postoperative tumor residue. Multivariate analysis indicated that age, invasion to esophagus and recurrence predict the prognosis. Conclusion DITC may be treated mainly by surgical operation. Radical resection is the key factor in the treatment of DITC. Patients with DITC have a relatively poor prognosis.Age, esophagus invasion and status of tumor residue are the most important factors affecting the prognosis.

ABSTRACT

OBJECTIVE To assess the outcomesof three different therapeutic approaches for the treatment of T3N0M0(stage Ⅲ) glottic squamous cell carcinoma. METHODS Sixty-five cases of T3N0M0 glottic squamous cell carcinoma treated with curative intent by three different modalities include vertical hemilaryngectomy(VHL,n=21),total laryngectomy(TL,n=31)and radiotherapy(RT,n=13) were reviewed retrospectively. The survival rate,recurrence rate at the primary lesion site and jugular lymph node, and laryngeal preservation was compared among three methods. RESULTS There was no significant difference in the overall survival rates(Cox proportion hazard model) and recurrence rates at the primary lesion site or jugular lymph node among the three methods. Laryngeal function was preserved in 100% of the cases in the VHL and RT groups after initial treatment. CONCLUSION The three treatment modalities had statistically similar survival and recurrence rates. Patients treated with VHL and RT had a higher rate of laryngeal preservation compared to that of TL, hence VHL or RT is a valid alternative to TL in treating selected patients with T3N0M0 glottic squamous cell carcinoma.

ABSTRACT

Objective To investigate the prognostic factors of differentiated thyroid carcinoma (DTC) in patients younger than 45 years. Methods Clinical data of all patients less than 45 years old at presentation with DTC in our hospital from Jan 1985 to Dec 1997 were analyzed retrospectively. Single variable analysis was performed by life-table method. Multivariate analysis was performed by Cox proportional hazard model. Results Two hundred and seventy two cases were analyzed. The overall 10-year survival rate was 93. 0%. The main prognostic factors influencing survival were age at presentation, the status of lymph node metastasis and distant metastasis; distant metastasis was the risk factor independently influencing survival by multivariate analysis. Conclusions Distant metastasis is the factor influencing survival significantly. The prognosis of these patients without distant metastasis is good. Total or near-total thyroidectomy and postoperative 131I therapy may be essential for a better prognosis in patients with distant metastasis.
