This study was undertaken to examine prognosis after resection for M1 disease in squamous cell esophageal carcinoma. Fifty-six patients with M1 esophageal cancer underwent esophageal resection with two or three-field nodal dissection from 1994 to 2001. Operative mortality occurred in 3 patients. Primary tumor sites were as follows; 10 upper, 23 middle, and 20 lower thoracic esophagus. They were found to have M1 disease by pathologic examination of dissected nodes, 24 M1a and 29 M1b. Forty-two patients (79%) were considered to have undergone curative resection. Chemotherapy and/or radiation therapy was given to 38 patients perioperatively. Recurrence was identified in 35 patients (66%) during a mean follow-up of 23 months. Overall median and 5-yr survivals were 19 months and 12.7%. Five-year survivals for M1a and M1b disease were 23.9% and 6.1%, respectively (p=0.0488). Curative resection tended to show better survival (p=0.3846). Chemotherapy and/or radiation therapy provided no advantage (p=0.5370). Multivariate analysis showed that M1b was significant risk factor over M1a disease. Our conclusion is that surgical resection can provide acceptable survival in thoracic squamous esophageal cancer with M1a disease. Survival differences between M1a and M1b disease support the current subclassification staging system.

The study aimed to analyze the clinicopathological features, treatment, and prognosis factors of primary esophageal small-cell carcinoma (PESC). The clinical records and follow-up data of 100 patients with PESC were collected, and the clinicopathological features and treatments were examined. Log-rank test and Cox regression model were performed to identify the independent prognostic factors. Progressive dysphagia, weight loss, and abdominal pain were the most common initial symptoms in the 100 patients with PESC. The primary tumor site mainly occurred in the middle of the chest (51%, 51/100), and the ulcer type was the most common under gastroscope (31%, 31/100). One or more positive markers of epithelial origin were present in all of the enrolled patients. At the time of diagnosis, 80 cases had limited disease (LD) and 20 cases had extensive disease (ED). The 1-, 3-, and 5-year survival rates of PESC patients were 57.0%, 18.0%, and 11.0%, respectively, with a median survival time (MST) of 13.8 months. In all PESC patients, multivariate Cox regression analysis indicated that the significant prognostic factors included the lesion length (=2.661, <0.001), TNM staging (=1.464, =0.016), and treatment methods (=0.333, <0.001). Besides, in patients with LD, the lesion length (=2.638, =0.001) and treatment methods (=0.285, <0.001) were independent prognostic factors. The MST of patients in surgery + chemotherapy group (21.6 months) was longer than that of the surgery only group (8.3 months, =0.021), while patients in surgery+ chemotherapy+ radiotherapy group were also associated with a longer MST than the chemotherapy + radiotherapy group (31.0 months, 9.8 months, respectively; <0.001). PESC is a rare esophageal malignant tumor with poor prognosis. Our findings reveal that the lesion length, TNM staging, and treatment method are independent prognostic factors for PESC patients. Moreover, surgery-based comprehensive treatments may prolong the survival of patients with LD.

OBJECTIVE: To determine the clinical application of the new classification of adenocarcinoma of esophagogastric junction (AEG). METHODS: The data of cancer of distal esophagus, cancer of cardia, and proximal gastric cancer were reviewed. Clinicopathologic characteristics, surgical modes and survival were analyzed according to Siewert's standards. RESULTS: Among the 203 patients that were up to the standard, 29 had adenocarcinoma of the distal esophagus (Type I), 80 had true carcinoma of cardia (Type II), and 94 had subcardial carcinoma (Type III). The 5-year survival rates of the 3 types of patients after the operation were 34% for Type I, 27.5% for Type II, and 24.5% for Type III (P<0.05). Further analysis of the patients with curative resection suggested there was no significant difference in the 5-year survival rates, with 37.5% for Type I, 34.5% for Type II, and 33.3% for Type III (P>0.05). CONCLUSION Difference has been found in the clinicopathologic characteristics of the 3 types of adenocarcinoma of the esophagogastric junction. The exact relation of the 3 types is still unknown. The TNM classification, complete tumor resection and the extent of lymph node metastasis are critical for the prognosis of the patients.

OBJECTIVETo review the experience of different surgical construction methods for hypopharyngeal cancer with cervical esophageal invasion.

METHODSFrom 1989 to 2000,forty-eight patients with advanced hypopharyngeal cancer and cervical esophageal invasion were retrospectively reviewed, including 38 males and 10 females. The median age was 54. 3 years old, ranged from 26 to 71 years old. According to UICC 1997 criteria, all the tumors were T4 stage and originated from the pyriform sinus (33), posterior pharyngeal wall (14), postcricoid area (1), there were 28 patients in cN0, 15 in cN1, 5 in cN2 and no distant metastasis. Precise preoperative evaluation was performed with computed tomography scan, barium swallow perspective and biopsy. All the patients received modified neck dissection, including both unilateral (38 patients) and bilateral (10 patients). Pharyngoesophageal defect reconstruction methods were: laryngotracheal flap in 11 patients, pectoralis major musculocutaneous flap in 13, laryngotracheal flap combined with pectoralis major musculocutaneous flap in 6, pectoralis major musculocutaneous flap combined with the split graft in 10, stomach pulling-up in 3, colon interposition in 5 patients. Total laryngectomy was carried out in 8 patients. All patients received radiotherapy postoperatively (dose 55 - 75 Gy).

RESULTSThe cervical lymph node metastasis was found in 20 patients. Pathologic findings showed that well, moderately and lower differentiated squamous cell carcinomas were 18, 24, 6 cases, respectively. The overall 3 and 5 year survival rates were 52.1% (25/48) and 27.3% (12/44), respectively. The 3 and 5 year survival rates in functionally preserved group were 65.2% (15/23) and 33.3% (7/21), while in non functionally preserved group were 40.0% (10/25) and 21.7% (5/23), respectively. Fifteen patients laryngeal functions (voice, respiration and deglutition) were completely restored and 8 patients partially restored (voice and deglutition). The decannulation rate was 65% (15/23). The complication included pharyngeal fistulas in 10 cases and splitting of chest wall in 1 cases.

CONCLUSIONSCombined therapy was the best choice for hypopharyngeal cancer with cervical esophageal invasion. The laryngeal function is preserved as far as possible. The continuity of the pharyngoesophagus was restored by pectoralis major musculocutaneous flap, laryngotracheal flap, or combined with the split graft. Stomach transposition or colon interposition was used while the defect of the esophagus was greater.

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.

BACKGROUND/AIMS: The aim of this study was to evaluate clinicopathologic differences between Type II and Type III groups that were classified by Siewert in cardia cancer. METHODS: A hundred forty-one patients who were diagnosed as gastric cardia cancer and underwent surgery between January 1990 and December 2006 by single surgeon at Department of Surgery, Yonsei University College of Medicine were included in this study. The Kaplan-Meier method and log rank test were used for survival analysis. RESULTS: Barrett's adenocarcinoma was recognized in two patients so called type I. There were significant differences between type II and III in aspect of depth of invasion, Lauren's classification, and the number of retrieved lymph nodes in which cancer infiltrated. In type III, prognostic factors affecting survival were depth of invasion and nodal status in contrast to the no demonstrable prognostic factors existing in type II. However, there were no differences in recurrence and survival between two groups. CONCULSIONS: Several clinicopathologic differences exist between type II and III cardia cancer. In the future, further evaluation is needed regarding the classification and entities of the cardia cancer.

OBJECTIVETo evaluate the surgical treatment and technical key-points of upper or middle thoracic esophageal carcinoma in patients with history of gastrectomy.

METHODSEighty-six patients with upper or middle thoracic esophageal carcinoma after previous gastrectomy received surgical treatment between 1980 and 2004. Among them, tumor location was in middle thoracic esophagus in 50 patients, in upper thoracic esophagus in 31 and cervical esophagus in 5. Postoperative pathological staging was stage I in 16 patients, stage IIa in 62, stage IIb in 5 and stage III in 8. The interval between gastrectomy and the diagnosis of esophageal carcinoma ranged from 2 to 22 years. Surgical procedures included esophagectomy and reconstruction with nonreversed gastric tube in 2 patients and reversed gastric tube in 3. The esophagus was reconstructed with short segment of colon in 5 patients and long segment of colon in 74. Two cases underwent jejunostomy only.

RESULTSSeventy-six patients (88%) were treated with curative intent. Seven patients (8%) received palliative surgery. Postoperative complication rate was 12% (10/86). One patient died of multiple organ dysfunction syndrome (MODS). Sixty-seven patients were followed up, the 1-, 3-, 5-year survival rates were 84% (56/67), 57% (38/67) and 22% (15/67), respectively.

CONCLUSIONSSurgical treatment is the first choice for esophageal cancer patients after gastrectomy although the procedures are complicated. The surgery should be considered as a reliable therapeutic modality because of favorable patient prognosis. The replacement with colon is recommended for those patients.

OBJECTIVETo evaluate the efficacy of esophagogastrostomy in the neck using circular mechanical stapler through the esophageal bed.

METHODSFrom March 1998 to June 2004 subtotal esophagectomy and mechanical anastomosis with stomach in the neck through the esophageal bed was carried out in 346 esophageal cancer patients.

RESULTSIn this series, the positive rate of detecting residual cancer cells in the esophageal stump was 1.2% (4/346); anastomotic fistula was observed in 5.5% (19/346) causing one patient died; the overall operative mortality rate was 0.6% (2/346); esophageal anastomotic stricture developed in 3.8% (13/346), which were cured by endoscopic dilatation.

CONCLUSIONThis modified operation mode has low rate of complication, reducing impairement to pulmonary function due to the transposed thoracic stomach within the mediastinum instead of the thoracic cavity. Using mechanical circular stapler for anastomosis in the neck simplifies the operation and reducing the postoperative risk caused by anastomotic leak.

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.

OBJECTIVE: To compare the long-term survival outcomes of Siewert II adenocarcinoma of esophagogastric junction (AEG) between transthoracic (TT) approach and transabdominal (TA) approach. METHODS: The databases of Gastrointestinal Surgery Department and Thoracic Surgery Department in West China Hospital of Sichuan University from 2006 to 2014 were integrated. Patients of Siewert II AEG who underwent resection were retrospectively collected. INCLUSION CRITERIA: (1) adenocarcinoma confirmed by gastroscopy and biopsy; (2) tumor involvement in the esophagogastric junction line; (3) tumor locating from lower 5 cm to upper 5 cm of the esophagogastric junction line, and tumor center locating from upper 1 cm to lower 2 cm of esophagogastric junction line; (4)resection performed at thoracic surgery department or gastrointestinal surgery department; (5) complete follow-up data. Patients at thoracic surgery department received trans-left thoracic, trans-right thoracic, or transabdominothoracic approach; underwent lower esophagus resection plus proximal subtotal gastrectomy; selected two-field or three-field lymph node dissection; underwent digestive tract reconstruction with esophagus-remnant stomach or esophagus-tubular remnant stomach anastomosis above or below aortic arch using hand-sewn or stapler instrument to perform anastomosis. Patients at gastrointestinal surgery department received transabdominal(transhiatal approach), or transabdominothoracic approach; underwent total gastrectomy or proximal subtotal gastrectomy; selected D1, D2 or D2 lymph node dissection; underwent digestive tract reconstruction with esophagus-single tube jejunum or esophagus-jejunal pouch Roux-en-Y anastomosis, or esophagus-remnant stomach or esophagus-tubular remnant stomach anastomosis; completed all the anastomoses with stapler instruments. The follow-up ended in January 2018. The TNM stage system of the 8th edition UICC was used for esophageal cancer staging; survival table method was applied to calculate 3-year overall survival rate and 95% cofidence interval(CI); log-rank test was used to perform survival analysis; Cox regression was applied to analyze risk factors and calculate hazard ratio (HR) and 95%CI. RESULTS: A total of 443 cases of Siewert II AEG were enrolled, including 89 cases in TT group (with 3 cases of transabdominothoracic approach) and 354 cases in TA group. Median follow-up time was 50.0 months (quartiles:26.4-70.2). The baseline data in TT and TA groups were comparable, except the length of esophageal invasion [for length <3 cm, TA group had 354 cases(100%), TT group had 44 cases (49.4%), χ²=199.23,P<0.001]. The number of harvested lymph node in thoracic surgery department and gastrointestinal surgery department were 12.0(quartiles:9.0-17.0) and 24.0(quartiles:18.0-32.5) respectively with significant difference (Z=11.29,P<0.001). The 3-year overall survival rate of TA and TT groups was 69.2%(95%CI:64.1%-73.7%) and 55.8% (95%CI:44.8%-65.4%) respectively, which was not significantly different by log-rank test (P=0.059). However, the stage III subgroup analysis showed that the survival of TA group was better [the 3-year overall survival in TA group and TT group was 78.1%(95%CI:70.5-84.0) and 46.3%(95%CI:31.0-60.3) resepectively(P=0.001)]. Multivariate Cox regression analysis revealed that the TT group had poor survival outcome (HR=2.45,95%CI:1.30-4.64, P=0.006). CONCLUSION The overall survival outcomes in the TA group are better, especially in stage III patients, which may be associated with the higher metastatic rate of abdominal lymph node and the more complete lymphadenectomy via TA approach.
