DESIGN: To investigate the frequency, treatment and clinical behaviour of differentiated microcarcinoma of the thyroid gland (PTMC). PATIENTS AND METHODS: Out of 376 patients submitted to surgical treatment for differentiated thyroid cancer from June 1980 to October 2003, 77 had been identified has having a PTMC (63 females, 14 males; mean age 43+/-13 years). Sixty-seven patients (87%) met the AMES risk definition for low (group I) and 10 (13%) for high-risk (group II) definition. The surgical procedures were lobo-isthmusectomy (n=14) or subtotal thyroidectomy (n=20) and total thyroidectomy (n=43) with node dissection in 15 cases. Follow-up ranging from 9 to 274 months (mean 124+/-84). RESULTS: Overall patient survival rates were 100 and 94% at 20 years in groups I and II, respectively (p=ns). There were no significant differences in surgical complications and in survival in patients submitted to total thyroidectomy when compared to partial thyroid resection. The presence of cervical node metastasis did not affect patient survival (p=0.8). The overall mean survival time was 266 months. CONCLUSIONS: Despite the overall excellent prognosis, PTMC was associated with a 1% disease-related mortality, a 2.5% local recurrence rate, 1% lymph-node recurrence rate, and 1% distant metastasis rate. We recommend total thyroidectomy accompanied by modified neck dissection if enlarged nodes are diagnosed. 相似文献

Papillary thyroid microcarcinoma: a surgical perspective 总被引:5,自引:0,他引:5
Papillary thyroid microcarcinoma (PTMC) is defined as a papillary thyroid cancer measuring less than 10mm in its greatest diameter. It is the most common form of thyroid cancer, detected in up to 36% in autopsy studies. The wide availability and use of neck ultrasonography in the evaluation of carotid arteries and of the thyroid resulted in an increased detection of PTMC. PTMC is often multifocal. The diagnosis is usually based on a combination of clinical examination, laboratory investigations, and specialized radiological techniques (mainly neck ultrasonography combined with fine-needle aspiration cytology). A common scenario is the diagnosis of PTMC as an incidental finding following thyroidectomy for a presumably benign thyroid disease. Despite some controversy, most authors agree that PTMC should be treated by total or near-total thyroidectomy, provided it can be performed safely. Because of its many and major advantages, in our clinical practice, total or near-total thyroidectomy is the procedure of choice for the management of PTMC. Given the high incidence of PTMC as an incidental finding and the frequent multi-focality, we also favor total or near-total thyroidectomy for the surgical management of nodular thyroid disease (multinodular goiter or dominant presumably benign thyroid nodule/s). Despite some controversy, we perform central neck lymph node dissection electively, in the presence of cervical lymphadenopathy. Radioiodine ablation therapy may be used as an adjuvant therapy. Prognostic factors (such as tumor multicentricity, positive lymph nodes, capsular or vascular invasion) or scoring systems (such as the AMES) can be used to select patients for radioiodine adjuvant therapy. Suppression therapy is needed after surgical management. Despite the potential for neck lymph node and even distant metastases, the biological behavior of PTMC is in general benign and the prognosis is very good. 相似文献

Background: The phenomenon of occult carcinoma maybe observed in patients with clinically unilateralpapillary thyroid microcarcinoma (PTMC). Although many studies have reported that the BRAFT1799A mutation isassociated with aggressive PTMC, the relationship between BRAFT1799A mutation and occult carcinoma is unclear.The aim of this study was to investigate the risk factors, including BRAFT1799A mutation, for occult contralateralcarcinoma in clinically unilateral PTMC accompanied by benign nodules in the contralateral lobe. Materialsand Methods: From January 2011 to December 2013,we prospectively enrolled 89 consecutive PTMC patientswith clinically unilateral carcinoma accompanied by benign nodules in the contralateral lobe who received atotal thyroidectomy and cervical lymph node dissection. BRAFT1799A mutation was tested by pyrosequencing onpostoperative paraffin specimens. The frequency and predictive factors for occult contralateral carcinoma wereanalyzed with respect to the following variables: age, gender, family history, tumor size, presence of Hashimotothyroiditis, extrathyroidal extension, central lymph node metastasis, multifocality of primary tumor, or BRAFT1799Amutation. Results: A total of 36 patients (40.4%) had occult PTMC in the contralateral lobe. The median diameterof the occult tumors was 0.33±0.21 cm. The BRAFT1799A mutation was found in 38 cases (42.7%). According to theunivariate analysis, there were no significant differences between the presence of occult contralateral carcinomaand age, gender, family history, tumor size, presence of Hashimoto thyroiditis, extrathyroidal extension, centrallymph node metastasis, multifocality of primary tumor, or BRAFT1799A mutation. Conclusions: Using currentmethods, it is difficult to preoperatively identify patients with PTMC, and further research is needed to determinepredictive factors for the presence of occult contralateral carcinoma in patients with unilateral PTMC. 相似文献

Purpose: To investigate the expression of Ki67 protein in papillary thyroid microcarcinoma(PTMC), and toanalyze its clinical significance. Materials and Methods: Ki67 protein expression was evaluated in the tissues of108 human PTMC and 50 other benign papillary hyperplasia of thyroid specimens using immunohistochemistry.Results: The expression intensity of Ki67 in PTMC and benign papillary hyperplasia of thyroid specimenswere 1.45±1.83% and 0.46±0.46%.The positive expression rates were 46.3% and 14%. There were significantdifferences between these two groups (p<0.01). There was no significant variation of the expression intensityand positive expression rates of Ki67 in PTMC with gender, age, position of the tumor and the level of TSHpre-operation (p>0.05), but these parameters varied with tumor size, invasion by membrane and cervical lymphnode metastasis (p<0.05 or p<0.01). Conclusions: The expression of Ki67 in PTMC was related to tumor size,invasion by membrane and cervical lymph node metastasis, and could be the important indicator for judgingclinical progress and estimating prognosis. 相似文献

Papillary thyroid microcarcinoma (PTMC): Prognostic factors, management and outcome in 403 patients 总被引:1,自引:0,他引:1
M.R. Pelizzo I.M. Boschin A. Toniato A. Piotto P. Bernante C. Pagetta L. Rampin D. Rubello 《European journal of surgical oncology》2006,32(10):1144-1148
AIM: To investigate an "optimal" therapeutic management of patients with papillary thyroid microcarcinoma (PTMC). METHODS: We evaluated a group of 403 consecutive patients affected by PTMC operated on by the same surgeon. Prognostic factors were evaluated by uni- and multivariate statistical analysis. RESULTS: After a mean follow-up of 8.5 years, 372 patients were living without disease (undetectable serum thyroglobulin levels), 24 patients were living with disease (increased serum thyroglobulin levels), 6 patients were deceased due to causes different from thyroid cancer, and 1 patient was deceased due to metastatic thyroid cancer. No statistically significant prognostic factor was found at uni- and multivariate analysis. However, it is worth noting that in patients with a larger primary tumour (size> or =5mm) and treated by partial thyroidectomy alone, the prevalence of recurrent disease was higher than in patients treated by total thyroidectomy and (131)I administration. CONCLUSION: It appears reasonable to perform total thyroidectomy (possibly associated with central compartment node dissection), (131)I whole body scan (followed by (131)I therapy when necessary) and TSH-suppressive hormonal therapy in patients with PTMC. 相似文献

Background: Papillary thyroid microcarcinoma (PTMC) has high incidence and low disease-specific mortality. However, active surveillance is not accepted by most patients owing to high physical or psychological pressures. The emergence of ablation technologies is supplanting traditional surgery. Our goal was to compare the clinical outcomes of microwave ablation (MWA) and surgery for T1aN0M0 PTMC.Methods: A total of 92 consecutive patients with T1aN0M0 PTMC were studied retrospectively. Forty-six patients had been treated with MWA, and the other 46 had undergone surgery. MWA was performed using extensive ablation extending from the nodule’s lower pole to the upper pole. Surgery was performed by total thyroidectomy or thyroid lobectomy. We compared the two groups in terms of mean length of stay, cost, mean blood loss, surgical incision, operating room (OR) time, quality of life (QOL) assessment, complications, and therapeutic efficacy over a follow-up period of 42 months.Results: The mean length of stay, cost, mean blood loss, surgical incisions, OR time, and complications in the MWA group were significantly lower than those of the surgery group. The QOL after MWA was higher than it was after surgery. The nodule volume decreased significantly from 53.61?±?48.43?mm3 to 4.84?±?6.55?mm3 (p?.001) at the 42-month follow-up, exhibiting a percentage volume reduction of 81.33?±?36.87%. No recurrence or metastasis occurred in either group during the follow-up period.Conclusions: MWA may be considered a minimally invasive alternative to surgery for solitary T1aN0M0 PTMC with low incidence of complications and good therapeutic effect. 相似文献

Papillary microcarcinoma (PMC) is a thyroid tumor measuring 10mm or less in maximum diameter and comprise up to 30% of all papillary thyroid cancers. Most of them are detected incidentally and defined as incidental papillary microcarcinoma (IPC=10mm). The incidence of such incidental cancers found in surgical specimens of benign thyroid diseases is high. Although most PMC are incidental, all incidental papillary cancers cannot be classified as microcarcinoma, owing to their size that may be larger than 10mm. Not much is known about the biological behavior and clinical course of IPC=10mm. There is an ongoing discussion among endocrinologists, endocrine surgeons and nuclear medicine specialists about the optimal therapeutic strategy for the patients with IPC=10mm. Some investigators advocate in favor of not performing further treatment in addition to initial thyroid surgery, whereas others suggest an aggressive surgical approach followed by radioiodine ablation therapy. Randomized prospective trials of observation versus standard thyroid cancer care are required to high-lighten this dilemma. 相似文献

Childhood and adolescent thyroid carcinoma 总被引:9,自引:0,他引:9
OBJECTIVES: This analysis was performed to evaluate the influence of clinical and treatment factors on local tumor control, control of distant metastasis, survival, and complications in children and adolescents with thyroid carcinoma. METHODS: The records of 56 children and adolescents with papillary and follicular carcinoma of the thyroid were reviewed. They ranged in age from 4 to 20 years. There were 43 females and 13 males. At diagnosis, 15 (27%) patients had disease confined to the thyroid, 34 (60%) had additional lymph node metastasis to the neck or upper mediastinum, and 7 (13%) also had lung metastasis. Treatment consisted of a total thyroidectomy in 48 patients, a subtotal thyroidectomy in 4 patients, and a lobectomy in 4 patients. All 56 patients received postoperative thyroid hormone suppressive therapy. (131)I was administered to 82% (46 of 56) of patients after their initial surgery. RESULTS: The overall survival rate was 98% with a follow-up of 0.6-30.7 years (with a median follow-up of 11.0 years). The one death that occurred in this patient population was the result of a congenital heart defect and was unrelated to thyroid carcinoma. The 10-year progression-free survival rate was 61%. Nineteen patients (34%) experienced a recurrence of their thyroid carcinoma. The time to first recurrence of disease ranged from 8 months to 14.8 years (mean, 5.3 years). None of those with disease confined to the thyroid developed recurrent disease. The recurrence rate was 50% (17 of 34) in patients with lymph node metastasis and 29% (2 of 7) in patients with lung metastasis (P = 0.02). Tumor characteristics were evaluated for time to first recurrence utilizing the logistic likelihood ratio test to predict disease recurrence. Thyroid capsule invasion (P = 0.02), soft tissue invasion (P = 0.03), positive margins (P = 0.006), and tumor location at diagnosis (thyroid only vs. thyroid and lymph nodes vs. thyroid, lymph nodes, and lung metastasis, P = 0.02) were significant for developing recurrent disease. Patients younger than 15 years old at diagnosis were more likely to have more extensive tumor at diagnosis than patients who were 15 years and older (thyroid only vs. thyroid and lymph nodes vs. thyroid, lymph nodes, and lung metastasis, P = 0.02). CONCLUSION: Carcinoma of the thyroid in children and adolescents has little risk of mortality but a high risk of recurrence. Younger patients present with a more advanced stage of disease and are more likely to have disease recurrence. Total thyroidectomy and lymph node dissection, followed by postoperative (131)I therapy, thyroid hormone replacement (suppressive) administration, and diligent surveillance are warranted. 相似文献

With the increasing incidence of papillary thyroid cancer (PTC), it is important to risk-stratify patients who may have a more aggressive tumor biology. The present study aimed to evaluate the risk factors for lymph node metastasis (LNM) in patients with PTC, which may provide a significant reference for clinical diagnosis and treatment. In total, 1,045 patients with PTC [313 with PT microcarcinoma (PTMC) and 732 with non-PTMC] between August 2016 and August 2019 were investigated. The B-type Raf kinase (BRAF) V600E mutation was tested in all samples. The clinical data (sex, age, tumor location, sample type and pathological features) were retrospectively analyzed. Logistic regression analysis was performed to evaluate independent risk factors for LNM. A total of 181/313 (57.8%) PTMC cases and 145/732 (19.8%) non-PTMC cases had a BRAF V600E mutation. In the PTMC cases, significant differences in sex and sample type were identified (BRAF V600E mutation vs. wild-type). In the non-PTMC cases, significant differences in sex and age were identified (BRAF V600E mutation vs. wild-type). Female sex and tumor diameter ≤1 cm were significant independent predictors of LNM in PTC. In PTMC, female sex was a significant independent predictor of LNM. A bilateral tumor was an independent protective factor for LNM in PTC, PTMC and non-PTMC. The BRAF V600E mutation rate of ultrasound-guided fine-needle aspiration cytology was higher compared with FFPE in PTMC (P=0.018). In contrast to previous studies, the results of the present study suggested that being female and having a tumor of diameter ≤1 cm were risk factors for LNM, and that the BRAF wild-type of PTMC may be more aggressive than other types. Notably, the position of the tumor in the bilateral thyroid was also an independent protective factor for LNM. Therefore, ultrasound-guided fine-needle aspiration should be recommended for gene analysis (BRAF V600E) in PTMC. In addition, clinicians should consider an individualized treatment according to gene mutations, sex, age, tumor size and the location of the tumor, in order to achieve an improved therapeutic efficacy. 相似文献

BACKGROUND AND OBJECTIVES: Within the group of patients with papillary thyroid microcarcinoma (PTMC), the prognostic factors have not been well defined and the optimal treatment has not been proved. The aim of this study was to find out the factors associated with the tumor recurrence in the patients with PTMC. METHODS: A total of 228 patients with PTMC (189 females, 39 males; age 14-85 years, median 46 years) were treated at our Institute between 1975 and 2006. The data on patients' gender, age, extent of disease, pathomorphological characteristics, therapy, locoregional control, disease-free survival and disease-specific survival were collected. Statistical correlation between possible prognostic factors and the duration of disease-free interval was analyzed by univariate and Cox's multivariate survival analysis. RESULTS: The tumor diameter ranged from 0.1 to 10 mm (mean 6.1 mm). The median length of observation was 84 months (range 1-385). During the follow-up period, the recurrence was diagnosed in 7 patients (6 locoregional and 1 distant). Multivariate analysis showed that tumor size and lymph node metastases were independent prognostic factors for disease-free interval. CONCLUSIONS: Longer disease-free interval was found in the patients with a tumor diameter < or =6 mm and without lymph-node metastases. 相似文献
