ABSTRACT

Objective: To compare the efficacies between open surgery and axillary non-inflatable endoscopic surgery in papillary thyroid carcinoma (PTC). Methods: A retrospective analysis was performed on 343 patients with unilateral PTC treated by traditional open surgery (201 cases) and transaxillary non-inflating endoscopic surgery (142 cases) from May 2019 to December 2021 in the Head and Neck Surgery of Sichuan Cancer Hospital. Among them, 97 were males and 246 were females, aged 20-69 years. 1∶1 propensity score matching (PSM) was performed on the enrolled patients, and the basic characteristics, perioperative clinical outcomes, postoperative complications, postoperative quality of life (Thyroid Cancer-Specific Quality of Life), aesthetic satisfaction and other aspects of the two groups were compared after successful matching. SPSS 26.0 software was used for statistical analysis. Results: A total of 190 patients were enrolled after PSM, with 95 cases in open group and 95 cases in endoscopic group. Intraoperative blood losses for endoscopic and open groups were [20 (20) ml vs. 20 (10) ml, M (IQR), Z=-2.22], postoperative drainage volumes [170 (70)ml vs. 101 (55)ml, Z=-7.91], operative time [135 (35)min vs. 95 (35)min, Z=-7.34], hospitalization cost [(28 188.7±2 765.1)yuan vs. (25 643.5±2 610.7)yuan, x¯±s, t=0.73], postoperative hospitalization time [(3.1±0.9)days vs. (2.6±0.9)days, t=-3.24], and drainage tube placement time [(2.5±0.8) days vs. (2.0±1.0)days, t=-4.16], with statistically significant differrences (all P<0.05). There was no significant difference in surgical complications (P>0.05). There were significant diffferences between two groups in the postoperative quality of life scores in neuromuscular, psychological, scar and cold sensation (all P<0.05), while there were no statistically significant differences in other quality of life scores (all P>0.05). In terms of aesthetic satisfaction 6 months after surgery, the endoscopic group was better than the open group, with statistically significant difference (χ2=41.47, P<0.05). Conclusion: Endoscopic thyroidectomy by a gasless unilateral axillary approach is a safe and reliable surgical method, which has remarkable cosmetic effect and can improve the postoperative quality of life of patients compared with the traditional thyroidectomy.

ABSTRACT

OBJECTIVES: The number of metastatic lymph nodes (LNs) and the ratio between the number of metastatic LNs and the total number of retrieved LNs (the LN ratio [LNR]) have been proposed as risk factors for recurrence of papillary thyroid carcinoma (PTC). However, the significance of the number of LNs and the LNR in patients with clinically node negative PTC has not been clearly determined. The purpose of this study is to evaluate their significance. METHODS: We retrospectively analyzed 382 patients with PTC who had undergone total thyroidectomy with prophylactic central neck dissection (CND) between January 2000 and December 2010. We excluded patients with lobectomy, concurrent lateral compartment neck dissection, a follow-up period less than at least 2 years, number of harvested central LNs less than or equal to one, clinically positive LN, distant metastasis, recurrent cancer or other types of malignancy. The correlations between recurrence and various clinicopathologic characteristics including tumor size, extrathyroidal extension (ETE), stage, number of metastatic central LNs, and the LNR were investigated. RESULTS: After a mean follow-up period of 82.2±26.4 months, recurrence occurred in 14 patients (3.7%). Tumor size ≥20 mm, maximal ETE, presence of central LN metastasis, number of metastatic LNs ≥2, and LNR ≥0.31 correlated with recurrence in the univariate analysis. However, tumor size ≥20 mm, maximal ETE, number of metastatic LNs ≥2, and LNR ≥0.31 were significantly associated with recurrence in the multivariate analysis (hazard ratio=6.61, 7.17, 3.43, and 11.23, respectively). CONCLUSION: The LNR and the number of metastatic LNs are independent prognostic risk factors for recurrence in patients with clinically node negative PTC, and these factors can be used to guide postoperative adjuvant therapy and follow-up strategy after prophylactic CND.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the aberrant promoter methylation of hMLH1 gene promoter and its clinical significance in papillary thyroid cancer (PTC).</p><p><b>METHODS</b>methylation of hMLH1 gene promoter in the cancer tissue and matched tumor-adjacent normal tissue of 152 PTC patients were detected by real-time methylation specific PCR (qMSP). The relationship between the methylation of hMLH1 gene promoter and clinicopathological features was analyzed.</p><p><b>RESULTS</b>The methylation rate of hMLH1 gene promoter in cancer tissues was 37.5% (57/152), of which 33 cases were totally methylated and 24 cases were partially methylated. The methylation rate of adjacent normal tissues was 5.3% (8/152)(all were partially methylated). The methylation rate of PTC tissues was significantly higher than that in the tumor-adjacent normal tissue (P < 0.01). The promoter methylation of hMLH1 gene in PTC was significantly correlated with age, size and number of the primary lesion, local invasion, T stage and lymph node metastasis (P < 0.05) , but not correlated with gender and clinical stage (P > 0.05).</p><p><b>CONCLUSION</b>Promoter methylation of hMLH1 gene is a common molecular event in PTC tissue, and it is significantly correlated with the progression of PTC.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To assess the epidermal growth factor receptor (EGFR) status in salivary adenoid cystic carcinoma and explore its role in cancer invasion.</p><p><b>METHODS</b>Fifty-four patients with pathologically confirmed salivary adenoid cystic carcinoma (SACC) were divided into invasion group and non-invasion group. The EGFR expression was determined by immunohistochemstry (SP staining). The relations between the EGFR expression and the SACC clinical pathological characteristics were analyzed.</p><p><b>RESULTS</b>EGFR were mainly expressed in the cell membrane and cytoplasm in the tissue of SACC. The positive rate of EGFR expression in the tumor tissue was 75.9% (41/54), and EGFR was over-expressed in the cytoplasm. The positive rate of EGFR expression in invasion group was higher than that in the non-invasion group (10.0%, P < 0.05). EGFR expression were related with the SACC T stages, histological types, distant metastasis, lymph node metastasis, and nerve invasion (P < 0.05).</p><p><b>CONCLUSIONS</b>A higher expression of EGFR gene in the cytoplasm may have important effect on the progression of invasive carcinoma. Further investigations are required to develop new strategy in the treatment of salivary adenoid cystic carcinoma.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the prognosis of adenoid cystic carcinoma (ACC) in salivary gland and its influencing factors.</p><p><b>METHODS</b>Clinical and following-up data of 76 patients with ACC in salivary glands were reviewed. Major gland tumors represented 35.5% whereas minor gland tumors comprised 64.5% of the cohort, with 8 cases (10.5%) in stage I, 23 (30.3%) in stage II, 18 (23.7%) in stage III and 27(35.5%) in stage IV. Survival rates were calculated by Kaplan-Merier method. Cumulative survival curves were evaluated using the Log-rank test. Multivariate analysis was performed by Cox proportional hazard model.</p><p><b>RESULTS</b>The regional recurrence rate was 28.9% and distant metastasis rate was 21.1%. The overall 5-year survival rate, tumor-free survival rate and tumor-related survival rate were 73.7%, 61.8% and 74.9% respectively. The overall 10-year survival rate, tumor-free survival rate and tumor-related survival rate were 48.2%, 39.8% and 56.2% respectively. Univariate survival analysis showed pathological type, clinical stage and perineural invasion were relevant to the prognosis of ACC and multivariate analysis showed they were the independent prognostic factors of ACC in salivary gland.</p><p><b>CONCLUSIONS</b>Clinical stage, pathological type and perineural invasion were the independent prognostic factors for adenoid cystic carcinoma in salivary gland. Surgery was the first choice for the treatment of adenoid cystic carcinoma in salivary gland, and postoperative radiotherapy may prolong the tumor-free survival time of patients in stage III and IV.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the prognosis of adenoid cystic carcinoma (ACC) in minor salivary glands and its influencing factors.</p><p><b>METHODS</b>Clinical data of 52 patients with ACC in minor salivary glands were reviewed. The distribution of stage was as follows: stage I (6%), stage II (21%), stage III (27%) and stage IV (46%). Counting data was analyzed by χ(2) test or Fisher's exact. Survival rates were calculated by Kaplan-Merier method. Statistical significance of differences in the cumulative survival curves was evaluated using the Log-rank test. Multivariate analysis was performed by Cox proportional hazard model.</p><p><b>RESULTS</b>All patients underwent primary tumor radical resection, 39 patients (75%) received postoperative radiation. The regional recurrence rate was 37% and distant metastasis rate was 21%. The 5-, 10-year cumulative local control rate were 68% and 63% respectively. The 5-, 10-year cumulative distant control rate were 86%, 68% respectively. The 5-, 10-year tumor specific survival rates were 70% and 54% respectively. Multivariate analysis showed that T stage, lymph node metastasis and perineural invasion were relevant to the tumor specific survival of ACC in minor salivary glands.</p><p><b>CONCLUSIONS</b>Recurrence and metastasis were the main cause of treatment failure of ACC in minor salivary glands. T stage, lymph node metastasis and perineural invasion were the independent prognostic factors of ACC in minor salivary glands. Radical surgery and reasonably postoperative radiotherapy were the main treatment strategy.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the evolution pattern of the Runx3 gene 5'-CpG island ~3478 bp region methylation in human salivary gland adenoid cystic carcinoma (SGACC).</p><p><b>METHODS</b>Quantitative MSP method was used to detect the methylation status of CpG island in various regions (No.1-10) of Runx3 promoter region, and Western blot was used for detection of the expression of Runx3 protein in 41 salivary gland SGACC samples and corresponding non-neoplastic salivary gland tissues. A Logistic model was used to analyze the risk ratio between the methylation status of CpG island in Runx3 gene and development of salivary SGACC, meanwhile, the possible association among the methylation of Runx3 gene, the clinicopathological parameters of SGACCs, and Runx3 protein expression was compared.</p><p><b>RESULTS</b>The results of qMSP showed that the hypermethylation initially occurred at the most 5' region of the Runx3 CpG island and spread to the transcription start site. The methylation rate was highest in region No. 1 and No. 2 among the successive ten regions ranging from the 5' region to the transcription start site within the Runx3 CpG island, and lowest in the transcription start site both in SGACCs and normal salivary glands. Furthermore, there was no methylation in the transcription start site in nomal salivary glands tissues. Together with the results of Logistic model analysis, those results indicate that the transcription start site within the Runx3 promoter CpG island is critical for gene silencing. Western blot results revealed that the Runx3 protein level in SGACC was significantly lower than that in normal salivary glands (P < 0.01). In combination of the results of qMSP, it is presumed that the Runx3 gene methylation is one of the reason inducing the down-regulation of Runx3 in SGACCs.</p><p><b>CONCLUSIONS</b>Methylation of the Runx3 CpG island spreads from the most 5'-region to the transcription start site in human salivary gland adenoid cystic carcinoma, and the transcription start site may be a critical region for the methylation of Runx3. The evolution pattern of Runx3 gene methylation is related to the tumorigenesis of SGACCs.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the disadvantage of nonstandard operation for thyroid papillary cancer, and the value of re-operation.</p><p><b>METHODS</b>Eight hundred and ninety three thyroid papillary cancer patients (332 patients who received nonstandard operation received re-operation and 561 patients who received first standard operation in Zhejiang Cancer Hospital from January 1990 to January 2000) were retrospectively reviewed.</p><p><b>RESULTS</b>Pathological results confirmed that there were 53.9% cases with residual cancer in re-operative specimen. The parathyroid was preserved in 74.1% cases in re-operation and 93.0% cases in standard operation (P < 0.01). The recurrent laryngeal nerve was injured in 3.3% cases in reoperation and 1.2% cases in standard operation (P < 0.05). The positive neck lymph node was 39.2% and 37.4% (P > 0.05), the 5-year local recurrence rate was 7.5% and 3.7% (P < 0.01), the total 5-year and 10-year cum-survival rates were 90.2%, 84.4% in patients with re-operation and 94.0%, 92.5% in patients with standard operation. The 10-year cum-survival rate were 67. 8% in patients with recurrence and 92. 9% in patients with non-recurrence in primary site respectively. Statistical analysis showed that the cancer recurrence influences the survival rate significantly (P < 0.01).</p><p><b>CONCLUSIONS</b>In consideration of the higher residual tumor rate in patients who received nonstandard operations, the re-operations were necessary. But the re-operation could also leads to higher recurrence rate and more functional injuries. The standardized primary operation should therefore be formulated and advocated.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy of surgery for the patients with pyriform sinus carcinoma and analyze the prognostic factors related to the cancer.</p><p><b>METHODS</b>Between December 1995 and December 2002, 62 patients with pyriform sinus cancer were treated in Zhejiang Tumor Hospital. There were 13 patients staged T1, 17 T2, 12 T3, 20 T4. Four patients received preoperative radiation and 40 patients had post-operative radiation. Among 62 patients, 33 patients were treated by partial laryngectomy, 29 patients were treated by total laryngectomy.</p><p><b>RESULTS</b>The survival rate was calculated with Kaplan-Meier method. The overall 3- and 5-year survival rates were 42.3% and 27.8%, respectively. The 3-year survival rate between partial and total laryngectomy was 51.9% and 29.9%. The 5-year survival rate between partial and total laryngectomy was 39.5% and 11.2% (chi2 = 4.14, P<0.05). Early stage and combined modality therapy were the independent favorable prognostic factors.</p><p><b>CONCLUSIONS</b>Early diagnosis with treatment and combined treatment are the most important factors influencing the survival of patients with pyriform sinus carcinoma. Partial laryngopharyngectomy is a suitable treatment for early and selected advanced pyriform sinus carcinoma with a good function and oncologic outcome.</p>
