ABSTRACT
Objective To analyze the treatment effect and factors affecting the prognosis in young people of papillary thyroid carcinoma (PTC).Methods A total of 69 PTC patients were reviewed retrospectively in Sun Yatsen University Cancer Center from Dec 1996 to Oct 2005.The prognostic status were compared using the Kaplan-Meier methods,the factors were analyzed by Log-rank test and the multiple factors were estimated by the Cox regression models.Results There were 26 males and 43 females.The median age was 24 years (mean:23.1 years).The average follow-up time was 113 months ranging from 73 to 174 months.20.3％ patients (14/69) experienced recurrence during follow-up time and 1.4％ patient (1/69) died.All the patients received levothyroxine after operation.The 10 year disease-free survival (DFS) rate of patients with or without extra thyroidal extension (ETE) of PTC was 29.6％ and 80.1％,respectively (P ＜ 0.01).Multivariate analysis showed that young PTC people with ETE had a worse prognosis (P =0.004).Conclusions Young papillary thyroid carcinoma patients had a favorable outcome.Surgical procedure was the first choice for this kind of patients.ETE was an independent factor for the recurrence of young PTC patients.
ABSTRACT
<p><b>OBJECTIVE</b>To study the short-term results and technological improvement of free anterolateral thigh (ALT) flaps in the reconstruction of circumferential hypopharyngeal defects.</p><p><b>METHODS</b>The free ALT flap with a reporter skin paddle was used in 22 cases with circumferential hypopharyngeal defects. The short-term results of reconstructive surgeries and key points, advantages and complications of this technique were summarized.</p><p><b>RESULTS</b>The length of circumferential hypopharyngeal defects ranged from 7 to 9 cm. ALT flap with an area of (8-9) cm × (11-18) cm was harvested. A reporter skin island with the skin area of (2.0-3.0) cm × (2.5-4.0) cm was designed. 91% (20/22) of ALT flaps survived. Two cases with flap necrosis underwent second reconstruction with a pedicled pectoralis major flap. All the patients had patent anastomotic lumen. Good postoperative subjective swallowing evaluation was obtained in 59% (13/22) of patients; 41% (9/22) of patients had acceptable swallowing results. Three patients (14%) presented with postoperative pharyngocutaneous fistula. One case recovered spontaneously in short-term and other two cases received the second reconstructive surgery.</p><p><b>CONCLUSIONS</b>The application of free ALT flap with a reporter skin paddle in the reconstruction of circumferential hypopharyngeal defect is technologically easy and reliable, with satisfying swallowing function and limited trauma.</p>

<p><b>OBJECTIVE</b>To investigate the number of dissected lymph nodes and the incidence of injury to parathyroid glands during surgery for papillary thyroid carcinoma (DTC) in young patients.</p><p><b>METHODS</b>This study collected clinicopathological data of 51 young patients with PTC. Of the 51 patients, 18 patients were classified into carbon nanoparticles group (CNP group) and 33 patients into traditional surgical group (TS group). The number of dissected lymph nodes and the incidence of injury to parathyroid glands were analyzed using Wilcoxon rank sum test and chi-square test.</p><p><b>RESULTS</b>There were 16 males and 35 females, with a male/female ratio of 1: 2.19. The age ranged from 14 to 29 (25 ± 3.9) years. There was no statistically significant difference in age, gender, T-classification, TNM stage and surgical procedures between two groups (P > 0.05). The total number of dissected lymph nodes in CNP group was higher than that in TS group (Z = -2.258, P < 0.05) . However, significant difference in the total number of metastatic lymph nodes between the two groups was not found (Z = -0.396, P > 0.05). In level VI, the detected lymph node number of group CNP was higher than that of TS group (Z = -2.461, P < 0.05) but there was no significant difference in the detected number of metastatic lymph nodes (Z = -1.396, P > 0.05) . The rates of injury to parathyroid gland were 5.5% in CNP group and 18.2% in TS group, respectively (χ(2) = 1.568, P > 0.05).</p><p><b>CONCLUSION</b>Carbon nanoparticles could be an effective lymph nodes tracer applying to PTC operation in young patients.</p>

Oral squamous cell carcinoma is characterized by high rate of recessive lymph gland metastasis. However, the treatment of early stage of neck lymph gland metastasis still remains large controversial. In this review, we were undertaken to assess the predictability of lymph node metastases by analyzing tumor thickness or depth and imaging. It is suggested that combined with imaging examination, elective neck dissection is a suitable choice for patient with > 4mm of primary tumor filtration.
ABSTRACT
Objective: To investigate the long-term effect of submandibular salivary gland transfer on xerostomia induced by radiation in patients with nasopharyngeal carcinoma (NPC). Methods: A total of 70 eligible patients with NPC were divided into the test group (36 cases) and the control group (34 cases). In the test group, the submandibular salivary glands were transferred to the submental space before conventional radiotherapy (XRT) and shielded during XRT. Submandibular gland function and salivary fluid before and after radiotherapy, questionnaire of xerostomia at 60 months after XRT, and 5-year survival rate were compared between the two groups. Results: At 5 years after XRT, the trapping and excretion function of submandibular glands were significantly better in the test group (P=0.000 and P=0.000, respectively). The mean weight of saliva after XRT was greater in the test group than in the control group (1.65gvs.0.73g, P=0.000). Incidence of moderate to severe degree of xerostomia was significantly lower in the test group than in the control group (12.9%vs.78.6%, P=0.000). No significant difference was found in 5 year survival rate between the two groups (86.1%vs.82.4%, P＞0.05). Conclusion: Submandibular gland transfer procedure is safe for NPC patients. It can prevent XRT induced xerostomia and improve the quality of life of NPC patients.
ABSTRACT
OBJECTIVE To investigate the use ofultrasonically activated scalpel (UAS) in open thyroid surgery. METHODS From February 2004 to March 2005, thyroidectomy were performed in 77 cases by the same operation team. Forty seven cases received UAS thyroidectomy and 30 cases underwent conventional thyroidectomy. The operation time, estimated blood loss in operation, postoperative draining volume within the 24 hours, the length of hospitalization and postoperative complications between two groups were compared. RESULTS The average operation time of lobectomy and total/subtotal thyroidectomy in the UAS group were 61?4.34 and 85?3.02 minutes, and in conventional group were 82?3.37 and 121? 2.51 minutes. There was a significant difference in average operation time (P0.05). CONCLUSION The use of UAS in thyroid surgery was safe and can reduce the operation time.
