BACKGROUNDThe effectiveness of chemoradiotherapy followed by surgery (CRTS) in patients with resectable esophageal carcinoma remains controversial. We performed a systematic review of the literature with meta-analysis.

METHODSElectronic databases were used to identify published studies between January 1992 and April 2012. Pooled relative risk (RR) with 95% confidence interval (95% CI) was utilized to estimate the strength of the association between CRTS and surgery alone (SA) survival of the resectable esophageal carcinoma patients. Heterogeneity and publication bias were also assessed in the present study.

RESULTSThe final analysis of 2755 resectable esophageal carcinoma cases from 21 randomized controlled trials (RCTs) are presented. Compared to the SA group, the 1, 3- and 5-year survival rates were significantly higher in the CRTS group (all P < 0.05); the 3- and 5-year survival rates for the Eastern patients, Western patients, patients undergoing concurrent chemoradiotherapy, patients with squamous cell carcinoma, patients undergoing High-dose radiotherapy (≥ 40 Gy), and patients given either "cisplatin + Fluorouracil" or "cisplatin + paclitaxel" chemotherapy were significantly higher in the CRTS group (all P < 0.05). There were no statistical significances in the 3- and 5-year survival rates for patients undergoing sequential chemoradiotherapy or patients with adenocarcinoma between the two groups (all P > 0.05). Compared to the RCTS group, the surgery rate in the SA group was higher (P < 0.05), while the CRTS group had significantly higher radical resection rate, R0 resection rate and lower postoperative local recurrence rate (all P < 0.05). The differences in postoperative complication incidence, post-operative distant metastasis and postoperative mortality rate were not statistically significant between the two groups (all P > 0.05).

CONCLUSIONCRTS can significantly improve the survival and surgical conditions of patients with resectable esophageal carcinoma.

BACKGROUND/AIMS: We investigated the clinical outcomes according to the method of treatment in synchronous esophageal and gastric cancer. METHODS: Synchronous esophageal squamous cell carcinoma and gastric adenocarcinoma were diagnosed in 79 patients between 1996 and 2010. We divided the patients into four groups according to treatment; Group 1 received surgical resection for both cancers or surgery for gastric cancer with chemoradiotherapy for esophageal cancer (n=27); Group 2 was treated by endoscopic resection with or without additional treatment (n=14); Group 3 received chemoradiotherapy only (n=18); and Group 4 received supportive care only (n=20). RESULTS: The median survival times in groups 1 and 2 were 86 and 60 months, respectively. The recurrence rate and mortality were 23% and 48%, respectively, in group 1 and 21% and 4%, respectively, in group 2. The median survival time was 12 months in group 3 and 9 months in group 4. Multivariate analysis showed that age (p<0.001) and treatment group (p=0.019) were significantly associated with death. Compared with group 1, treatment in the intensive care unit (p=0.003), loss of body weight (p=0.042), and decrease in hemoglobin (p=0.033) were worse in group 1. CONCLUSIONS: Endoscopic resection for synchronous esophageal and gastric cancer could be considered as a possible alternative to surgery for early-stage cancer.

OBJECTIVETo analyze the relation between pathologic tumor response in preoperative radiotherapy and long-term survival in patients with esophageal carcinoma and the significance of radiosensitivity in the treatment of esophageal carcinoma.

METHODS176 esophageal cancer patients received preoperative radiotherapy and tumor resection from 1977 to 1989. The radio-response was classified into severe, moderate and mild according to the tumor pathologic response to radiotherapy. 191 patients treated by surgery alone served as control. The relation between radiation response of tumor and long-term survival and disease free survival was analyzed.

RESULTSThe 5-year survival rates of severe, moderate, mild and control groups were 60.7%, 46.4%, 21.1% and 38.8%. The survival was significantly improved in severe than moderate one (P = 0.029), moderate than mild group (P = 0.013) and severe than the control group (P = 0.000). It was only slightly improved in the moderate than control group (P = 0.295), but decreased in mild than the control group (P = 0.034). The 5-year disease-free survival (DFS) rates were 55.7%, 40.7%, 18.7% and 33.3% in severe, moderate, mild and control groups. The DFS was significantly improved in severe than moderate group (P = 0.029), moderate than mild group (P = 0.018), severe than the control group (P = 0.000 4). It was only slightly improved in moderate than the control group (P = 0.23), but decreased in the mild than the control group (P = 0.096). In the severe group, the proportion of stage T4, N1 lesion, TNM stage I-II and number of radical resection were 9.8%, 18%, 90.2%, and 90.2%. In the moderate group, they were 20.3%, 15.9%, 79.7% and 82.6%. In the mild group, they were 42.2%, 37.8%, 53.3% and 46.7%. In the control group, they were 50.3%, 40.8%, 37.7% and 77.5%. The rates of downstaging and surgical resection were improved only in severe and moderate groups (P < 0.01).

CONCLUSIONThe fact that only patients in whom severe radiation response are observed would appreciably benefit from preoperative radiotherapy whereas the others do not, illustrates that there might be no benefit of radiotherapy for radioresistant esophageal carcinoma. Radiosensitivity measurement before preoperative radiotherapy would be valuable for individualized treatment.

OBJECTIVETo study the prognostic factors affecting the survival rate after extended radical esophagectomy with three-field lymph node dissection for squamous cell carcinoma and the effect of postoperative chemotherapy.

METHODSOut of 126 patients with original squamous cell carcinoma of esophagus who accepted extended radical esophagectomy with three-field lymph node dissection from 1987 - 1992 in a hospital, 97 of them were included in this study. Data on the clinical/pathological characters and post surgery survival records of the subjects' were collected. Survival analysis methods included Kaplan-Meier, Log-rank test and Cox multivariable model and the effects of postoperative chemotherapy were analyzed for patients in early and late stages.

RESULTSThere was no significant difference in clinical and pathological character between those patients only undergone surgery and patients accepting postoperative chemotherapy. The size of tumor, grade of differentiation of the tumor cells, infiltration deepness, with or without lymph node metastasis, expression of nm23 and EGFR and treatment after surgery etc. were correlated with the survival rate. For patients in early tumor stage, postoperative chemotherapy with cisplatin and 5-FU after surgery seemed to be a risk factor. For patients in late stage, postoperative chemotherapy with cisplatin and 5-FU after surgery did not seem to improve survival rate.

CONCLUSIONIt is imperative to study on the effect of adjuvant postoperative chemotherapy to patients, especially those at early stage with squamous cell carcinoma of esophagus. Doctors must be scrupulous when making decisions.

OBJECTIVETo explore the surgical treatment of primary small-cell esophageal carcinoma (PSEC).

METHODSWe retrospectively analyzed the clinical data of 73 patients with PSEC who received surgical treatment in our hospital from 1984 to 2003.

RESULTSThe overall resection rate was 94.5%. The complete resection rate was 89.0% and operation mortality was 1.4%. The 1-year, 3-year, and 5-year survival were 50.7%, 13.7%, and 8.2%, respectively.

CONCLUSIONSPSEC is a rare malignant tumor with poor prognosis. Surgical resection is the main method for patients in stage I or II, and postoperative chemotherapy seems to be helpful. Patients in stage Ill or IV should be managed with chemotherapy and radiotherapy.

OBJECTIVETo investigate the application of bundles of intervention in the treatment of esophageal carcinoma anastomotic leak.

METHODSFrom January 2014 to May 2015, 44 cases of esophageal carcinoma anastomotic fistula were treated by bundles of intervention (through the collection of a series of evidence-based treatment and care measures for the treatment of diseases) in Department of Thoracic Surgery, Huai'an First Hospital, Nanjing Medical University (bundles of intervention group), and 68 patients with esophageal carcinoma postoperative anastomotic leak from December 2013 to January 2012 receiving traditional therapy were selected as the control group. The clinical and nutritional indexes of both groups were compared.

RESULTSThere were no significant differences in general data and proportion of anastomotic leak between the two groups. Eleven patients died during hospital stay, including 3 cases in bundles of intervention group(6.8%) and 8 cases in control group (11.8%) without significant difference(P = 0.390). In bundles of intervention group, 1 case died of type III( intrathoracic anastomotic leak, 2 died of type IIII( intrathoracic anastomotic leak. In control group, 2 cases died of type III( cervical anastomotic leak, 2 died of type III( intrathoracic anastomotic leak and 4 of type IIII( intrathoracic anastomotic leak. The mortality of bundles of intervention group was lower than that of control group. The duration of moderate fever [(4.1±2.4) days vs. (8.3±4.4) days, t=6.171, P=0.001], the time of antibiotic use [(8.2±3.8) days vs.(12.8±5.2) days, t=5.134, P = 0.001], the healing time [(21.5±12.7) days vs.(32.2±15.8) days, t=3.610, P=0.001] were shorter, and the average hospitalization expenses[(63±12) thousand yuan vs. (74±19) thansand yuan, t=3.564, P=0.001] was lower in bundles of intervention group than those in control group. Forty-eight hours after occurrence of anastomotic leak, the levels of hemoglobin, albumin and prealbumin were similar in both groups. However, at the time of fistula healing, the levels of hemoglobin [(110.6±10.5) g/L vs.(103.8±11.1) g/L, t=3.090, P=0.002], albumin [(39.2±5.2) g/L vs.(36.3±5.9) g/L, t=2.543, P=0.013] and prealbumin [(129.3±61.9) g/L vs.(94.1±66.4) g/L, t=2.688, P=0.008] were significantly higher in bundles of intervention group.

CONCLUSIONIn the treatment of postoperative esophageal carcinoma anastomotic leak, application of bundles of intervention concept can significantly improve the nutritional status and improve the clinical outcomes.

OBJECTIVETo evaluate the clinical value of prophylactic radiotherapy for esophageal carcinoma after curative operation.

METHODS495 esophageal squamous cell cancer patients who had undergone radical resection were randomized by the envelope method into a surgery alone group (S, 275) and a surgery plus radiotherapy group (S + R, 220). Radiation treatment was started 3 - 4 weeks after operation. The portals encompassed the whole mediastinum and bilateral supraclavicular areas. A mid-plane dose of 50 approximately 60 Gy in 20 approximately 30 fractions over 5 approximately 6 weeks was delivered.

RESULTS1. Survival rate: the overall 5-year survival rate was 39.4%. Those of S alone and S + R groups were 37.1% and 41.3% (P = 0.447 4). The 5-year survival rate for Stage III patients were 13.1% in S alone group and 35.1% in R + S group (P = 0.002 7), 2. Pattern of failure: The incidence of local recurrence intra-thoracic lymph node metastasis, anastomotic recurrence and extra-thoracic lymph node metastasis in S + R group (16.2%, 0.5% and 3.1%) were lower than those (25.9%, 5.8% and 13.2%) (P < 0.05) in S alone group and 3.

COMPLICATIONSthe anastomotic stricture frequencies were similar in the two groups (S 1.8%; S + R 4.1%).

CONCLUSION1. Prophylactic radiotherapy is able to improve the survival rate of stage III patients treated by radical resection, 2. Postoperative radiotherapy is able to reduce the incidence of failure by recurrence in the intra-thoracic lymph nodes and anastomotic recurrence to where radiation therapy had been given, 3. Postoperative radiotherapy does not increase the incidence of anastomotic stricture.

OBJECTIVETo explore the effect and possible mechanism of traditional Chinese medicine (TCM) on survival and quality of life (QOL) in patients with esophageal carcinoma after esophagectomy.

METHODSAdopting prospective controlled method of study, the authors had 128 post-esophagectomy patients, hospitalized from February 2001 to February 2002, randomly divided into 3 groups: the TCM group, treated with TCM drugs alone; the chemotherapy group, with chemotherapy alone applied; and the synthetic group, treated with chemotherapy combined with Chinese medicine. Their survival rate and QOL were compared.

RESULTSIn the TCM group, the chemotherapy group and the synthetic group, the respective 3-year relapse and remote metastasis rate were 71.4%, 76.7%, 53.4%, respectively (chi(2) = 6.53, P < 0.05); the 1-year survival rate 42.9%, 46.5%, 72.1%; 2-year survival rate 28.6%, 27.9%, 55.8%, and 3-year survival rate 26.2%, 23.1%, 37.2%, respectively. And the QOL improving rate was 69.0%, 37.2%, 58.1%, respectively, all showing significant difference among them (chi(2) = 6.10, all P < 0.05). Moreover, immune function was increased in the TCM and the synthetic groups.

CONCLUSIONIntegrative Chinese and Western medicinal treatment was the beneficial choice for post-operational patients with esophageal carcinoma. However, long time use of simple Chinese medicine was also advisable, especially for those in poverty.
