Recent advances in the surgical treatment of pancreatic cancer

INTRODUCTIONPancreatic cancer remains the fourth commonest cause of cancer related death in the western world[1]. The prognosis remains dismal due partly to late presentation, with associated low resectability rates, and the aggressive biological nature of these tumors. The median survival time from diagnosis in unresectable tumors remains only 4 6 months.For those patients amenable to surgical resection over the last 20 years have seen marked improvements in postoperative mortality and morbidity, especially in specialist pancreatic centres 23. Despite these changes long-term survival remains low. with a total 5-year survival rate remaining less than 5%.Patients with ampullary cancer have a better 5-year survival of 40°%-60°%.

Surgical Treatment of Carcinoma of Esophagus and Gastric Cardia—A 34—year Investigation

Objective To understand the progress in surgical treatment of 12 970 patients with carcinoma of esophagus and gastric cardiac during 1965-1998.Methods The patients were divided into A, B and C groups: 3 155 patients (group A) were treated surgically in the first 14 years, 5952 patients (group B) in the next 10 years, and 3 863 patients (group C) in the last 10 years. The early stage lesions (Tis, Tl) were assigned as a separate group. The results of these groups were compared.Results The resectability for esophageal and gastric cardiac carcinoma was 94.0% and 84.4% respectively, and the overall resectability was 91.3% . The resectabih'ty for groups A, B, C and the early stage group was 82.1% , 85.1% , 90.2% and 100% , respectively. The overall operative mortality was 1.8%, it was 4.4% for group A, 1.6% for group B, and 0.5% for group C. The overall 5-year survival was 31.6% . The 5-year survival for groups A, B, C and the early stage group was 27.0% , 29.1%, 32.0% and 92.6%, respectively . Among the 3 temporal groups, differences were observed in terms of lesion stage, location and size, surgery with or without combined therapy and postoperative complications.Conclusion Best results were achieved in the early cases, with a resectability of 100% and a 5-year survival of 92.6% . The indications for surgical treatment were extended with increased resectability and decreased mortality. Subtotal esophagectomy combined with cervical esophagogastrostomy was advocated as the procedure of first choice for esophageal carcinoma in attempt to diminish the chance of recurrence, and to achieve better outcomes by using combined therapy for patients with e" stage b! lesion.

Radiotherapy combined with surgical treatment for gastric cancer:a meta-analysis

Objective:We carried out a meta-analysis to assess the effectiveness and safety of radiotherapy combined with surgery for gastric cancer.Methods:Randomized Clinical Trials (RCTs) in which radiotherapy (preoperative,intraoperative and postoperative),was compared with surgery alone in resectable gastric cancer were identified by searching Cochrane Library (Issue 2,2009),PubMed (Jan 1966-Jun 2009),EMBASE (Jan 1974-Jun 2009),Chinese Biomedical Literature Database (Jan 1978-Jun 2009),Chinese Science and Technology Periodicals Database (Jan 1989-Jun 2009),China National Knowledge Infrastructure (Jan 1994-Jun 2009) and Wanfang database (Jan 1997-Jun 2009) in English and Chinese languang.Two researchers assessed the quality of included randomized controlled trials (RCT) extracted data independently.The RevMan 5.0 software was used for meta-analysis.Our researchers assessed the quality of included randomized controlled trials (RCT) extracted data independently.The RevMan 5.0 software was used for meta-analysis.Results:Nine randomized controlled trials of 1 548 patients were selected for meta-analysis.Five randomized controlled trials were related with comparison of preoperative radiotherapy plus surgery with single surgery.Two randomized controlled trials were the comparative studies between surgery plus postoperative and single surgery.The meta-analysis results showed that:(1) compared with surgery alone,preoperative radiotherapy combined with surgery can increase 3 years (OR=1.78;95% CI 1.14-2.78,P=0.01),5 years (OR=1.67;95% CI 1.22-2.29,P=0.001),10 years (OR=1.64;95% CI 1.03-2.60,P=0.04) survival rate and resection rate (OR=2.15;95% CI 1.31-3.54,P=0.003);reduce the of tumor recurrence rate (OR=0.59;95% CI 0.37-0.92,P=0.02) and metastasis rate (OR=0.44;95% CI 0.27-0.73,P=0.001);(2) The tumor recurrent rates (OR=0.19,95% CI 0.03-1.14,P=0.07) and tumor metastasis rate (OR=0.09;95% CI 0.00-1.77,P=0.11) had no difference between single surgery group and peri-operative radiotherapy plus surgery group;(3) Postoperative radiotherapy compared with surgery alone had no significant effects on 1 year (OR=0.83;95% CI 0.60-1.15,P=0.26) and 3 years (OR=0.75;95% CI 0.51-1.11,P=0.15) survival rate compared with single surgery,but the 5-year survival rates (OR=0.57;95% CI 0.34-0.95,P=0.03) of the patients who received surgery alone was higher than those who received combined therapy.No difference of the tumor recurrence rate (OR=0.59;95% CI 0.33-1.05,P=0.07),tumor metestasis rate (OR=0.90;95% CI 0.51-1.59,P=0.71) and anastomotic leak (OR=0.98;95% CI 0.25-3.65,P=0.98) were observed between the two groups.Conclusion:Preoperative radiotherapy combined surgery is more rational and effective than surgery alone of gastric cancer.However,in terms of the clinical effects of perioperarive or postoperative radoiotherapy combined with surgery,much multicenter,largescale,high-quality,double-blind and rigorously designed studies would be needed than currently available in the future.

Application of mastoscopic in modified radical operation for preserving nipple-areolar complex

Objective: To probe the effect of mastoscopic in modified radical mastectomy operation for preserving nipple-areolar complex in the treatment of breast cancer.

Analysis on relative factors of lymph node metastasis and pattern of postoperative locoreginal relapse of esophageal carcinoma

Objective: We aimed to study the relative factors of lymph node metastasis of esophageal carcinoma, and to analyze the distribution rule of lymph node metastasis of post esophagectomy patients for guiding the radiotherapy. Methods: To collect the patients' data (102 cases) in our hospital from 2001 to 2009, who were found lymph node metastasis confirmed by pathologic in a certain period of time after esophageal cancer surgery. The factors affected the lymph node metastasis in esophageal cancer were analysed by single logistic regression and Logistic Regression Method. To analyze the rule of post-operative lymph node metastasis in different regions, according to the lymph node partition, in accordance with paragraphs of esophageal cancer in different groups. Results: Of the 102 patients after esophageal cancer surgery, who were confirmed by pathological examination, 50 cases had positive lymph node metastasis and 52 cases had negative, the lymph node metastasis rate was 49.0%. Lymph node metastasis rates of different depth, length and paragraph of tumor invasion had statistical difference (P < 0.05). The impact on lymph node metastasis rates of the different age and degree of differentiation had no statistical difference (P > 0.05). Multivariate analysis showed that the lesion length, depth of invasion and paragraph of tumor were meaningful factors affecting the lymph node metastasis. Of the 102 patients, 132 sites node metastasis were found by imaging study and histopathology with lower neck and supraclavicular node 59 (44.70%), upper mediastinum node 51 (38.64%), A-P windows node 1 (0.76%), anterior mediastinum node 1 (0.76%), Subcarinal node 5 (3.79%), paraesopha- geal node 3 (2.27%), hilar node 3 (2.27%), abdominal node 9 (6.82%). Conclusion: The length and depth of invasion, and paragraph of esophageal cancer are meaningful factors that affect the lymph node metastasis. The longer of lesion, deeper of infiltration and lower of paragraph, the easier to get independently lymph node metastasis. The postoperative lymph node metastasis was mainly distributed in the lower neck and supraclavicular region and upper mediastinal region, which is the focus of postoperative radiotherapy.
