Abstract： Objective To analyze the modes and rules of subcarinal lymph node metastasis in non-small cell lung cancer patients， and explore appropriate surgical dissection strategy of subcarinal lymph nodes for patients with non-small cell lung cancer. Methods The clinical data of 608 patients with non-small cell lung cancer who underwent lung resection and systematic lymph node dissection in Henan Cancer Hospital from September 2002 to October 2011 were analyzed retrospectively. There were 388 males and 220 females with an average age of 62.3 （45-78） years. There were 122 patients with left upper lobe tumor， 119 patients with left lower lobe tumor， 158 patients with right upper lobe tumor， 40 patients with right middle lobe tumor and 169 patients with right lower lobe tumor. Subcarinal lymph node metastasis was observed in 118 patients （19.4%）. There were 244 patients with squamous carcinoma， 285 patients with adenocarcinoma and 79 patients with other types of carcinoma. The relationship of subcarinal lymph node metastasis with tumor location， pathological types and clinicopathological characteristics were analyzed. Results There was statistical difference in subcarinal lymph node metastasis rate among different tumor locations （P=0.000）. Subcarinal lymph node metastasis rate was the highest ［45.8% （54/118）］ in patients with right lower lobe tumor. For patients with different pathological types， subcarinal lymph node metastasis rate was the highest ［55.9% （66/118）］ in patients with adenocarcinoma， and then squamous carcinoma （P=0.034）. Subcarinal lymph node metastasis rate increased with the increase in T staging， and patients with tumors located in the middle or lower lobe of the left or right lung had a significantly higher subcarinal lymph node metastasis rate than patients with upper lobe tumor. Conclusion Subcarinal lymph node metastasis rate are lower in patients with left or right upper lobe tumor， patients with squamous carcinoma whose clinical T staging is within cT 1 .
Barrett’s esophagus is considered an important risk factor for the pathogenesis of esophageal adenocarcinoma. Treatment strategies for diseases from high-grade dysplasia （HGD） to adenocarcinoma are different. The recurrence rates of endoscopic treatment and anti-reflux surgery are comparatively higher. Abnormal lesions of the esophagus can be completely resected by esophagectomy for the treatment of HGD to adenocarcinoma, and treatment outcomes are confirmed.But appropriate surgical strategies and lymph node dissection scopes should be chosen according to different cancer staging.Lymph node metastasis is a major factor in determining prognosis.
Objective To investigate the feasibility, curative effect and perioperative treatments of lobectomy for pulmonary diseases by complete videoassisted thoracoscopic surgery (VATS). Methods Fiftysix patients of pulmonary diseases were treated with thoracoscopic lobectomy (including mediastinal and hilar lymph node dissection for malignant diseases) from March 2006 to November 2007 in our Department. Twelve right upper lobectomy, three right middle lobectomy, fifteen right lower lobectomy, nine left upper lobectomy, fourteen left lower lobectomy and three bilobectomy were carried out. The bilobectomy included one right upper and middle lobectomy, two right middle and lower lobectomy. Mediastinal and hilar lymph node dissection was simultaneously performed in the malignant cases. The feasibility, safety and postoperative complications were retrospectively analyzed. Results Fiftytwo patients (92.8%) were performed successfully by complete VATS. The median operative duration and blood loss were respectively 107±29min(from 45min to 168min) and 121±32 ml(from 50ml to 310ml). The incision in two cases (3.6%) were elongated to around 8 cm, the ribs were retracted, and the operations were completed by the help of VATS. Another two patients (3.6%) were changed to conventional thoracotomy for pneumonectomy or hemostasis. The postoperative pathology diagnosis was lung cancer in thirty nine, tuberculoma in seven, inflammatory pseudotumor in four, indurative angioma in four, bronchiectasis in one and metastasic chondrosarcoma in one. There was no surgical mortality. One case suffered from atelectasis in the middle lobe postoperatively and was cured by phlegm suction with bronchoscopy. Two air leakage healed automatically in three days. No other severe complications was observed. The average postoperative hospitalization was 8.9±3.1 d(from 8 d to 14 d). Conclusion Lobectomy for pulmonary diseases by complete VATS is technically fieasible, safe, minimally invasive with less complications and fast rehabilitation.
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 longterm 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 5year and 10year 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.
Objective To provide a current language for clinical and pathological discription of gastric cancer. Methods The literature in recent years on the distribution of lymph nodes and staging of gastric cancer were reviewed. Results The lymph nodes of gastric cancer are distributed near the blood vessel and organs of gastric milieu. To ensure radical gastrectomy rational and scientific, the anatomic structure of gastric milieu should be familiarized. Conclusion The excellent outcome of surgery will be achieved by the effective dissection and removel of lymph nodes in gastric cancer.
Objective To evaluate the safety and advantage in lymph node dissection of Ivor-Lewis esophagectomy in patients with esophageal cancer. Methods Clinical and pathological data of 78 patients with esophageal cancer who underwent Ivor-Lewis esophagectomy between September 2012 and March 2014 were collected and analyzed. Another 86 esophageal cancer patients who underwent esophagectomy of Sweet procedure during the same period were regarded as the controls. Duration of surgery, intra-operative blood loss, incidence of main complications and positive rate of lymph node were compared between the two groups. Results The duration of surgery in Ivor-Lewis group [(254.5±38.4) minutes] was longer than that in the Sweet group [(216.7±31.3) minutes]; and the average intra-operative blood loss in Ivor-Lewis group [(165.5±40.3) mL] was higher than that in the Sweet group [(148.7±35.4) mL]; the differences were significant (P < 0.01). Incidence of hoarseness in Ivor-Lewis group was significantly higher than that in Sweet group (P < 0.05), while incidences of other comp lications between the two groups were similar (P > 0.05). The proportion of patients with positive lymph nodes in Ivor-Lewis group (60.3%, 47/78) was significantly higher than that in Sweet group (26.7%, 23/86) (P < 0.05). Average number of lymph nodes dissected in Ivor-Lewis group (21.5±5.3) was significantly higher than that in Sweet group (10.6±4.1). Lymph nodes along the right recurrent laryngeal nerve was the most common metastasis in patients of Ivor-Lewis group, while lymph nodes in that area in Sweet group patients could hardly be dissected. Conclusions Ivor-Lewis esophagectomy is a safe surgical procedure for esophageal cancer. Ivor-Lewis procedure has more advantages in lymph node dissection than Sweet procedure.
ObjectiveTo explore the safety, effectiveness, and cosmetic advantage of endoscopic thyroidectomy for differentiated thyroid cancer in the cT1N0 stage. MethodsThe clinical data of 148 patients underwent thyroidectomy for the cT1N0 differentiated thyroid cancer in the First Affiliated Hospital of PLA General Hospital and the PLA General Hospital from September 2010 to September 2013 were analyzed retrospectively, including 36 patients by total endoscopic thyroidectomy (TET group), 41 patients by endoscopic-assisted thyroidectomy (EAT group), and 71 patients by open thyroidectomy (OT group). The intraoperative status, early complications, late complications, and cosmetic result were compared among these three groups. ResultsAll the procedures were accomplished successfully.①In the intraoperative status: The operation time of the TET group was significantly longer than that of the EAT group(P < 0.05)or OT group (P < 0.05), drainage on the first day after operation in the TET group was significantly more than that in the EAT(P < 0.05)or OT group (P < 0.05), the intraoperative bleeding of the TET group or EAT group was significantly less than that of the OT group (P < 0.05), there were no statistical significances in the total number of lymph nodes dissection and number of positive lymph nodes among three groups (P > 0.05).②In the early complications: The postoperative pain score of the TET group was significantly lower than that of the EAT group (P < 0.05)or OT group (P < 0.05), there were no statistical significances in the postoperative bleeding, seroma, infection, transient recurrent laryngeal nerve paralysis, or transient hypoparathyroidism among three groups (P > 0.05).③In the late complications: there was no statistical significance in the perpetual recurrent laryngeal nerve paralysis, perpetual hypoparathyroidism, or thyroid cancer relapse among three groups (P > 0.05).④The best cosmetic result was obtained by the patients underwent TET as compared with the patients underwent EAT(P < 0.05)or OT (P < 0.05). ConclusionsEndoscopic procedure has the same effectiveness and safety with open procedure for differentiated thyroid cancer in the cT1N0 stage, but endoscopic procedure has a better cosmetic result than that open procedure. Compared with EAT, TET has more advantages in the cosmetic result.
ObjectiveTo investigate the feasibility,safety and short-term clinical outcomes of complete videoassisted thoracoscopic surgery (VATS) lobectomy for patients with early-stage lung cancer (LC). MethodsClinical data of 138 consecutive patients with early-stage LC who underwent lobectomy in the First People's Hospital of Jining from January 2012 to May 2013 were retrospectively analyzed. There were 71 patients undergoing complete VATS lobectomy including 39 male and 32 female patients with their age of 57.9±10.6 years (VATS group) and 67 patients undergoing lobectomy via traditional thoracotomy including 36 male and 31 female patients with their age of 60.3±8.2 years (thoracotomy group). Operation time,intraoperative blood loss, groups and number of lymph node dissection,thoracic drainage duration, postoperative hospital stay,vision analogue scores (VAS) on the 1st,3rd and 30th postoperative day, and postoperative morbidity were compared between the 2 groups. ResultsAll the patients in both groups success fully received their operation. Intraoperative blood loss (147±113 ml vs. 146±91 ml) number of lymph node dissection (9.9±3.6 vs. 10.0±3.6) group of lymph node dissection (3.1±1.3 vs. 3.4±1.3) and VAS on the 1st and 3rd postoperative day of VATS group were not statistically different from those of the thoracotomy group (P>0.05). Operation time (119±27 minutes vs. 135±29 minutes) thoracic drainage duration (3.0±0.9 days vs. 3.8±1.2 days) postoperative hospital stay (8.0±2.1 days vs. 10.2±5.4 days) VAS on the 30th postoperative day (2.6±0.7 vs. 3.2±1.1) and postoperative morbidity (8.5% vs. 19.4%) of VATS group were significantly shorter or lower than those of the thoracotomy group (P<0.05). Fifty-nine patients in VATS group and 58 patients in the thoracotomy group were followed up for 2-18 months after disc harge. During follow-up,there was no death in either group. There was 1 patient with brain metastasis,1 patient with liver metastasis,and 2 patients with bone metastasis. ConclusionComplete VATS lobectomy is safe and feasible for the treatment of early LC with the advantages of minimal invasiveness,less morbidity,better postoperative recovery and less chronic incision pain. Complete VATS lobectomy can also achieve similar standardization of lymph node dissection as routine thoracotomy.
ObjectiveTo evaluate the metastasis feature and the dissecting value of cervicothoracic lymph node for middle esophageal squamous carcinoma. MethodsA total of 303 patients admitted to the Rugao Boai Hospital(107 patients) and the Rugao People's Hospital (196 patients) received the stapled cervical esophagogastrostomy via different thoracic approach according to the admission order number between March 2005 and February 2013. There were 290 patients with Ro resections including 149 patients by Ivor-Lewis approach (an Ivor-Lewis group) and 141 patients by Sweet approach (a Sweet group). The data of lymph nodal dissection and PTNM stage and follow-up of the two groups were analyzed. ResultsThe number of positive lymph nodes dissected from the cervicothoracic junction in the IvorLewis group was significantly greater than that in own upper abdomen (Z=3.12, P<0.05) and that in the cervicothoracic junctionin in the Sweet group (Z=3.30, P<0.05). The lymph node metastasis rate of the cervicothoracic junction in the Ivor-Lewis group was significantly higher than that in own upper abdomen(χ2=10.76, P<0.05)and that in the cervicothoracic junction in the Sweet group (χ2=7.34, P<0.05). The lymph node ratio (LNR) of the cervicothoracic junction in the Ivor-Lewis group was significantly higher than that in own upper abdomen (χ2=11.67, P<0.05) and that in the cervicothoracic junction in the Sweet group (χ2=5.99, P<0.05). The proportion of patients which PTNM were Ⅲa or Ⅲb as N＞N1 in the Ivor-Lewis group was significantly higher than that in the Sweet group(χ2=5.59, P<0.05). After surgery of 1 year, 3 years, 5 years, the rate of lymph node local recurrence and the total rate of tumor metastasis or recurrence in the Ivor-Lewis group were significantly lower than in the Sweet group (P<0.05). The survival rate in the Ivor-Lewis group was significantly greater than that in the Sweet group (P<0.05). ConclusionThe cervicothoracic junction has a higher incidence of lymphatic metastasis, which transfer intensity is greater than that of upper abdomen. The extended cervicothoracic lymph node dissection should be indeed indispensible to increase of radical resection and the accuracy of PTNM stage and to improve the long term survival for middle esophageal carcinoma.
ObjectiveTo observe the outcome of left lung cancer underwent surgical treatment and to analysis the relative risk factors for 4L lymphatic metastasis. MethodsWe retrospectively analyzed the clinical data of 643 lung cancer patients who had underwent mediastinal lymph node dissection intraoperatively in our hospital between January 2011 and December 2013. There were 430 males and 213 females with a mean age of 60.2±9.6 years(range 22 to 83 years), 260 patients had their 4L lymph node dissected, while other 383 patients did not. ResultsAmong 260 patients with 4L lymph node dissected, 44(16.9%) were found 4L lymph node metastasis pathologically. And the results indicated that station 5 lymph node metastasis(P=0.000, OR=12.108 with 95%CI 4.564 to 32.122), station 7 lymph node metastasis(P=0.000, OR=8.496 with 95%CI 2.594 to 27.827), station 8 lymph node metastasis(P=0.029, OR=24.915 with 95%CI 1.395 to 444.948), station 10 lymph node metastasis(P=0.014, OR=3.983, 95%CI 1.321 to 12.009) were independently associated with high risk for 4L lymph node metastasis. Conclusion4L lymphadenectomy should be performed for left invasive lung cancer regularly, especially for patients with hilar lymph node and other mediastinal lymph node metastasis.
