  • Significance and Surgical Skill for Lymphadenectomy Around Common Hepatic Artery in Gastric Cancer

    Objective To investigate the significance and surgical skill for lymphadenectomy around common hepatic artery in gastric cancer. Methods Two hundred and fifty-seven cases with undergoing lymphadenectomy around common hepatic artery in gastric cancer between January 2001 and December 2006 were retrospectively reviewed. Experiences and understanding of dealing with this procedure in curative gastrectomy for gastric cancer were concluded. Results The number of dissected No.8 lymph node was 2.2±1.7, and the positive rate of No.8 lymph node was 30.35%. There were no lymphadenectomy related complications, such as anastomotic leakage, lymphatic fistula and postoperative hemorrhage in this series. Dissection around common hepatic artery lymph nodes along artery intrathecal space, division and ligation of left gastric vein at its root, and sufficient exposure of anatomic structures were important to dissection lymph nodes around the common hepatic artery. The exposure of anatomic structures included liberation of common hepatic artery by traction with the band, and the exposure of posterior side of pancreas by Kocher incision.Conclusion Being familiar with the anatomy around common hepatic artery, careful dissection, and attention to the surgical skill of lymphadenectomy are very important to improve the effectiveness of lymphadenectomy around common hepatic artery in gastric cancer.

  • TRANSPOSITIONAL ANASTOMOSIS OF C7 POSTERIOR ROOT AND SPINAL ACCESSORY NERVE TO RECONSTRUCT THE TRAPEZIUS MUSCLE FUNCTION

    Objective To introduce a new approach of neurotization to treatment of the shoulder syndrome after the radical neck dissection by using transpositional anastomosis of C7 posterior root and the spinal accessory nerve to reconstruct the function of trapezius muscle. Methods From March 1999 to February 2001, 10 patients underwent the neurotization during the radical neck dissection. In the operation, the apo-cranial part of spinal accessory nerve was preserved from the trapezius muscle (gt;3.0 cm in length) and anastomosed to C7 posterior root. Objective physical examinations and electromyography were conducted before and after operation.One, 6 and 12 months after operation the trapezius muscle function after the transpositional anastomosis was evaluated. Results One, 6 and 12 months after operation, the recovery rates of each part were as follows: 9.8%, 68.9% and 73.5% in upper part; 4.7%, 73.6% and 69.4% in middle part; and 6.2%, 70.5% and 70.3% in lower part. The range of abduction motion of upper arm in 7 cases (70%) exceeded 90°. The mean maximal abduction angle was more than 95°. Evaluation of the shoulder function showed that myoatrophy was mild and the disability of abduction was classified as grade Ⅱ in 7 cases and grade Ⅲ in 3 cases. Conclusion Transpositional anastomosis of the C7 posterior root to thespinal accessory nerve after radical neck dissection can well reconstruct the function of trapezius muscle. This approach provides a wide indication in comparison with the functional neck dissection without impairment of arm function afterthe cutting of C7.

  • Primary Study on Metastatic Rate and Metastasis of Subpyloric Lymph Nodes in Gastric Cancer

    ObjectiveTo explore the value on excision of subpyloric (No.6 group) lymph nodes of stomach by detection of metastatic rate and metastasis of lymph nodes of No.6 group and its subgroups. MethodsThe clinical data including complete information on No.6 group and its subgroups lymph nodes in 80 patients underwent gastrectomy and subpyloric lymph nodes dissection for gastric cancer from January 2006 to December 2009 were retrospectively analyzed. Referring to the right gastroepiploic vein, the No.6 lymph nodes were divided into three subgroups (No.6a, No.6b, and No.6c subgroup), and the relationship between the metastasis of No.6 lymph nodes and clinicopathologic features as well as the metastasis of No.7, No.8a, and No.9 lymph nodes were analyzed by logistic regression analysis. ResultsThe metastatic rate of No.6 group lymph nodes was 41.3% (33/80) and with 26.0% (108/415) of the resected lymph nodes involved. The metastatic rate of lymph nodes in No.6a subgroup (7.5%, 6/80) was significantly lower than that in No.6b (16.3%, 13/80) and No.6c subgroup (36.3%, 29/80), Plt;0.001. The metastasis of the resected lymph nodes in No.6a, No.6b, and No.6c subgroup was 25.0% (8/32), 17.6% (13/74), and 28.2% (87/309), respectively, and the difference was not significant (P=0.292). The metastasis of lymph nodes in No.6a subgroup was correlated to T stage (P=0.042) and N stage (P=0.006). The metastasis of lymph nodes in No.6b subgroup was correlated to N stage (P=0.002) and TNM stage (P=0.013). The metastasis of lymph nodes in No.6c subgroup was correlated to differentiation degree of tumor (P=0.008), T stage (P=0.003), N stage (P=0.000), and TNM stage (P=0.000). The logistic regression analysis showed that the metastasis of lymph nodes was correlated to the metastasis of No.8a lymph nodes (P=0.023) and N stage (P=0.002) in No.6 group, the metastasis of No.8a lymph nodes (P=0.018) in No.6a subgroup, N stage (P=0.005) in No.6b subgroup, and the metastasis of No.8a lymph nodes (P=0.016) and N stage (P=0.004) in No.6c subgroup. ConclusionAttentions should be paid to the complete dissection of subpyloric lymph nodes in gastric cancer surgery, especially for the lymph nodes of No.6a and No.6b subgroups.

  • The Application of Intraoperative Nerve Monitoring in Assessing The Function of The Recurrent Laryngeal Nerve before and after Central Lymph Node Dissection

    ObjectiveTo discuss whether central lymph node dissection (CLND) should be performed for papillary thyroid cancer (PTC) patients. MethodsThe related domestic and foreign literatures were retrieved, the necessity of CLND and the risk of recurrent laryngeal nerve (RLN) injury in CLND were reviewed, and the application value of intraoperative nerve monitoring (IONM) in CLND were analyzed. Results① CLND can reduce the recurrence rate of PTC, improve postoperative survival rate, ease the difficulty of reoperation, and help to clarify tumor stage. ② CLND can increase the risk of RLN injury. ③ Application of INOM can decrease the risk of RLN injury. ConclusionsThe application of IONM during CLND effectively decrease the risk of RLN injury for surgeons, especially low seniority surgeons, and improve the survival quality and the prognosis. This combination will promote the implementation of routine CLND therapeutic strategy in thyroid cancer patients.

  • A feasibility study on breast cancer patients with 1–2 positive sentinel lymph nodes to avoid axillary lymph node dissection

    Objective To explore the feasibility of breast cancer patients in China with 1–2 positive sentinel lymph nodes (SLN) to avoid axillary lymph node dissection (ALND). Methods A total of 328 patients who received sentinel lymph node biopsy (SLNB) in our hospital from 2010 to 2016 were collected retrospectively, and patients met the criteria of Z0011 clinical trials (which required no acceptance of neoadjuvant therapy, clinical tumor size was in T1/T2 stage, two or less positive SLNs were detected, received breast-conservation surgery, acceptance of whole breast radiotherapy after surgery and neoadjuvant systemic treatment) were enrolled to breast-conservation group. Patients met the criteria of Z0011 clinical trials, excepting the surgery (received non-breast-conservation surgery), were enrolled to non- breast-conservation group. Comparison of clinicopathological features between the breast-conservation group/non-breast-conservation group and the Z0011 ALND group was performed. Results Among the 328 patients, only 29 patients (8.8%) completely correspond with the results of Z0011 clinical trials. There was no statistical significance between the breast-conservation group and the Z0011 ALND group in the age, clinical T stage, expression of estrogen (ER), expression of progesterone (PR), pathological type, histological grade, number of positive lymph nodes, and incidence of non-sentinel node metastasis (P>0.05). A total of 81 patients were included in the non-breast-conservation group. It showed no statistical significance between the non-breast-conservation group and the Z0011 ALND group in expressions of ER and PR, and histological grade (P>0.05), while there was statistically significant difference in age, clinical T stage, pathological type,number of positive lymph nodes, and incidence of non-sentinel node metastasis (P<0.05). Patients in the non-breast-conservation group showed a lower age, higher percentage of lobular carcinoma and T2 stage, more positive lymph nodes, and high incidence of non-sentinel node metastasis. Conclusion It’s feasible for Z0011 clinical trials results to be used in the clinical practice of our country, but the actual situation of breast conservation in our country may lead to low adaptive population.

  • Research progress in the relationship between cN0 multifocal thyroid micropapillary carcinoma and central lymph node metastasis

    Objective To summarize the latest research progress on the relationship between cN0 multifocal papillary thyroid microcarcinoma (PTMC) and central lymph node metastasis (CLNM) at home and abroad, so as to provide a reference for surgeons to balance the benefits and risks of surgery and select the best treatment plan. Method The latest studies on the relationship between CLNM and tumor characteristics of cN0 multifocal PTMC (including number of tumor foci, total tumor diameter, primary tumor diameter, total tumor surface area, etc.) were reviewed. Results Current domestic and international guidelines differ on whether cN0 PTMC should be used to prevent central lymph node dissection (pCLND). Proponents believe that pCLND could reduce the recurrence rate of disease and facilitate postoperative risk stratification and management under the premise of technical support. Opponents argue that it was not clear whether pCLND actually improves the prognosis of PTMC patients, but postoperative complications do correlate with pCLND. In order to guide the application of pCLND in the surgical treatment of cN0 PTMC, a large number of studies had reported the risk factors of CLNM in PTMC in recent years, among which multifocal was considered to be a very important risk factor for CLNM. In order to further understand the internal relationship between multifocal PTMC and CLNM, scholars at home and abroad quantified the feature of multifocal PTMC into various parameters, and studied the relationship between them and CLNM in multiple dimensions. It was found that total tumor diameter >1 cm, increased tumor number, total tumor surface area >3.14 cm2, diameter ratio <0.56, tumor volume >90 mm3 and bilateral multifocal PTMC might be the risk factors for increased CLNM risk in patients with cN0 multifocal PTMC. Conclusion These screened parameters are initially considered to be effective tools for predicting the risk of CLNM in multifocal PTMC. Multiple risk parameters coexist, especially in patients with multifocal PTMC characterized by bilateral intralar multifocal PTMC, who are expected to benefit more from pCLND. However, a large number of clinical studies are still needed to provide reliable evidence-based evidence for clinical diagnosis and treatment. In the future, by combining these valuable parameters, a scoring system can be constructed to predict the disease status of multifocal PTMC more accurately and identify patients with necessary pCLND, which will be of great significance for the appropriate treatment of PTMC.

  • Clinical Significance of Bilateral Supraclavicular Lymph Node Dissection for Intrathoracic Esophageal Carcinoma

    Abstract: Objective To evaluate the clinical significance of bilateral supraclavicular lymph node dissection after esophagectomy for patients with intrathoracic esophageal carcinoma. Methods A total of 197 patients with esophageal carcinoma but no obvious supraclavicular lymph node metastasis who underwent esophagectomy in Zhongshan Hospital of Xiamen University from March 1997 to September 2004 were included in this study. All the patients were divided into 2 groups, the control group and the study group. In the control group (non-supraclavicular lymphadenectomy group), there were 96 patients including 62 males and 34 females with their age of 40-69 (55.2±3.1) years, who received 2-field lymphadenectomy (intrathoracic lymphatic drainage area and left paracardial lymph nodes) without supraclavicular lymph node dissection. In the study group (supraclavicular lymphadenectomy group), there were 101 patients including 68 males and 33 females with their age of 41-68 (53.8±4.5) years, who received 3-field lymphadenectomy including intrathoracic lymphatic drainage area, left paracardial lymph nodes and bilateral supraclavicular lymph node dissection. Postoperative survival rate, lymph node metastasis rate, anastomotic site recurrence rate, and long-term supraclavicular lymph node metastasis rate were compared between the 2 groups. Results The overall 5-year survival rate of all the patients was 39.59% (78/197). There was no statistical difference in 5-year survival rate between the 2 groups [37.50% (36/96) vs. 41.58%(42/101), P>0.05]. However, the 5-year survival rate of the patients with esophageal carcinoma in the upper third of the esophagus in the study group was significantly higher than that of the control group [38.10%(8/21) vs. 29.17% (7/24), P<0.05]. The intrathoracic lymph node metastasis rate (14.58% vs. 12.87%), abdominal lymph node metastasis rate (6.25% vs. 7.92%)and anastomotic site recurrence rate (5.20% vs. 5.94%)of the control group and study group were not statistically different (P>0.05). However, long-term supraclavicular lymph node metastasis rate of the study group was significantly lower than that of the control group (2.97% vs. 8.33%, P<0.05) Conclusion Bilateral supraclavicular node dissection can significantly increase postoperative survival rate and decrease long-term supraclavicular lymph node metastasis rate of patients with esophageal carcinoma in the upper third of the esophagus.

  • Long-Term Effects of Partial Axillary Dissection in Modified Radical Mastectomy of Breast Cancer

    Objective To study the effects of partial axillary lymph node dissection (PALD) on prognosis and upper limb function in patients with breast cancer. Methods Ninety-eight breast cancer patients with stage Ⅰ and Ⅱ were randomly divided into two groups and different surgical procedures following modified mastectomy were performed: partial axillary lymph node (level Ⅰ and Ⅱ) dissection (PALD) group (n=48) and total axillary lymph node (levelⅠ, Ⅱ and Ⅲ) dissection (TALD) group (n=50). The longterm positive relapse rate and upper limb function between 2 groups were compared. Results During the follow-up of 5 to 10 years (average 4.5 years), there were 2 cases (4.2%) of local recurrence on chest wall and one case (2.1%) of recurrence in axillary lymph node and one case (2.1%) of recurrence in supraclavicular lymph node in PALD group, and 2 cases (4.0%) of local recurrence on chest wall and no axillary lymph node recurrence and one case (2.0%) of recurrence in supraclavicular lymph node happened in TALD group. There was no statistical difference between PALD group and TALD group (Pgt;0.05). The incidence of upper limb edema and dysfunction was 4.2% (2/48) in PALD group and 16.0%(8/50) in TALD group (P<0.01). There was no significant statistical difference of 5year and 10year survival rate between PALD group and TALD group (89.6% vs. 88.0%, 79.2% vs. 78.0%,Pgt;0.05). Conclusion PALD may reduce upper limb dysfunction after operation in patients with stage Ⅰ and Ⅱ breast cancer, and does not increase prognostic risk.
