Abstract
PURPOSE Patients with unresectable cT4b esophageal cancer (EC) are rare and largely excluded from prospective trials. As a result, current treatment recommendations are based on limited evidence. This study sought to evaluate national practice patterns and outcomes for this population and evaluated 3 primary cohorts: patients receiving chemotherapy (CT) with or without subtherapeutic radiotherapy (RT), definitive chemoradiotherapy (CRT), or CT with or without RT followed by definitive surgery. MATERIALS AND METHODS The National Cancer Data Base was queried for cT4b Nany M0 EC. Exclusion criteria were patients with unspecified staging, palliative treatment, improper, or no histologic confirmation, or lack of CT. Multivariable logistic regression determined factors predictive of receiving surgical therapy. Kaplan-Meier analysis evaluated overall survival (OS), and Cox proportional hazards modeling determined variables associated with OS. RESULTS Altogether, 519 patients met inclusion criteria; 195 (38%) underwent CT, 291 (56%) underwent definitive CRT, and 33 (6%) underwent surgical-based therapy. Surgery was more likely performed in patients residing in rural areas, living farther from the treating facility, and N1 status (P<0.05 for all). Median OS in the respective cohorts were 6.0, 12.7, and 43.9 months (P<0.001). On multivariate Cox proportional hazards modeling, among others, nonsurgical treatment was associated with poorer OS (P<0.05 for both). CONCLUSIONS In the largest study to date evaluating patterns of care for cT4b EC, as compared with CT alone, addition of definitive RT was associated with higher OS. Although causation is clearly not implied, well-selected responders to CT and/or RT may be able to undergo resection and numerically prolonged survival, but patient selection remains paramount.

Abstract
INTRODUCTION The surgical technique for esophagectomy to treat esophageal malignancies has been improved over the past several decades. Nevertheless, it remains extremely difficult to surgically treat patients with locally advanced T4b tumors invading the aorta or respiratory tract. PRESENTAION OF CASE A 37-year-old Japanese man was diagnosed with T4b (descending aorta) N2M0, Stage IIIC middle thoracic esophageal squamous cell carcinoma. He was initially treated with definitive CRT followed by 3 courses of DCF. After the DCF, CT showed that the main tumor had shrunk and appeared to have separated from the descending aorta. Therefore we decided to perform a salvage esophagectomy. Because we needed the ability to closely observe the site of invasion to determine whether aortic invasion was still present, half the esophageal resection was performed under right thoracotomy, but the final resection at the invasion site was performed under left thoracotomy. Consequently, the thoracic esophagus was safely removed and aortic replacement was avoided. The patient has now survived more than 30 months after the salvage esophagectomy with no additional treatment for esophageal cancer and no evidence of recurrent disease. DISCUSSION Because this and the previously reported procedures, each have particular advantages and disadvantages, one must contemplate and select an approach based on the situation for each individual patient. CONCLUSION Salvage esophagectomy through a right thoracotomy followed by careful observation of the invasion site for possible aortic replacement through a left thoracotomy is an optional procedure for these patients.

Abstract
The history of esophageal surgery in Japan can be divided into three periods, an era of safety from 1930 to 1980, an era of radicality from 1980 to 2000, and the era of quality of life (QOL) from 2000 to the present. The treatment for T4 cancers of the thoracic esophagus has also changed over time from preoperative radiotherapy, combined resection of the neighboring organs with esophagectomy, and to definitive chemoradiotherapy (dCRT) with salvage surgery. At present, almost all patients with an unresectable T4 esophageal cancer receives dCRT. However, there are many patients with a residual or recurrent tumor after dCRT. Salvage surgery for such patients often results in incomplete resection of the tumor because the tumor involves the trachea and/or aorta. New techniques to enable the resection of such neighboring organs even during salvage surgery are needed. In the future, the mainstay of treatment for esophageal cancer will be CRT with the foreseeable progress in new drugs and new techniques of radiotherapy. Surgery will be indicated for a local failure after CRT, while combined resection of the neighboring organs will be necessary to treat a local failure after CRT for T4 cancers. New surgical techniques have to be developed through some application of new devices and equipment.

Abstract
Advanced esophageal tumors have been a challenge for surgery since the very beginning, and these challenges continue still today. In the early period of three-field lymphadenectomy (late 1980s), there was no special attention paid to tracheal necrosis after such an extended operation. In 1988, we reported functional mediastinal dissection preserving the right bronchial artery to prevent such complications. In 1993, we reported that the survival after three-field lymphadenectomy was better than that after en-bloc esophagectomy, and then the lymph node compartment classification based on the metastatic rate and the survival rate. This concept was introduced into the 9th edition of the Guidelines for Clinical and Pathologic Studies on Carcinoma of the Esophagus published in 1999. In early 1980s, combined resection of the neighboring organs was initiated for a locally advanced esophageal cancer. Almost all patients who underwent such an operation, however, died of metastasis in the short-term after surgery without any additional treatment. In 1987, we reported several types of tracheal repair using the latissimus dorsi muscle flap, as a less-invasive surgery that enabled adjuvant or additive therapy, after resection of the trachea involved by cancer. Then in 2004, we demonstrated that the canine aorta could be resected even immediately after aortic stenting. This suggests that an esophageal cancer involving the aorta can be resected using a new technique. To meet the challenges posed by advanced esophageal cancer, the help of other specialized fields besides esophageal surgery is needed: "The specialist must know everything of something, something of everything."

Abstract
Thoracic esophageal cancers frequently metastasize to the right recurrent nerve nodes (RRNNs). In fact, huge RRNNs invading the trachea sometimes remain after definitive chemoradiation therapy (CRT), despite complete remission of the primary lesion. We performed salvage lymphadenectomy of a large RRNN combined with partial resection of the trachea in two patients. Using an anterior approach, we removed part of the sternum, clavicle, and the first and second costal cartilage; then, we removed the RRNNs with combined resection of the lateral quarter circumference of the trachea, the esophageal wall, and the recurrent nerve. Reconstruction was done with a musculocutaneous patch of major pectoral muscle to cover the tracheal defect. The only minor complication was venous thrombosis in one patient. Thus, combined removal of the RRNN and trachea was performed safely as a salvage operation after definitive CRT for esophageal squamous cell carcinoma.

Abstract
In patients with advanced oesophageal carcinoma with aortic invasion, any therapy potentially causes fatal haemorrhage. We describe here the successful application of intra-aortic stent graft to prevent haemorrhage before radical oesophagectomy for advanced oesophageal cancer. Four patients with advanced oesophageal cancer complicated by invasion of the aorta. Under general anaesthesia, aortic invasion is evaluated by an intravascular sonography. The stent graft is passed through the right femoral artery into the descending aorta. Subsequently, the stent graft is released to expand in the thoracic aorta during an artificial cardiac arrest. Aortography is performed to check for any stent migration or endoleakage. This procedure was successful in all four patients without any complications. All patients underwent radical oesophagectomy following aortic stent-grafting. One patient survived more than 2 years after stent grafting and operation. This procedure is safe and applicable for the patient with aortic invasion before radiochemotherapy or operation.

Abstract
BACKGROUND Squamous cell carcinoma of the esophagus (ESCC) is radiosensitive; however, surgeons frequently encounter ESCC that survives radiotherapy to grow more rapidly and invasively. This alteration of tumor behavior may result from tumor hypoxia induced by radiotherapy. METHODS Forty-four patients with advanced (T3 and T4) ESCC, who underwent radiotherapy before operation, either with 40 Gy for preoperative treatment or 60 Gy or more for radical treatment, and 44 patients without preoperative therapy were subjected to retrospective immunohistochemical study. CD34 for tumor vessels, glucose transporter 1 (GLUT1) which was induced by hypoxia, MIB-1 for proliferating activity, and p53 were stained for surgical samples from ESCC patients. Tumor tissue at the invading front was the focus of evaluation. Macroscopic morphologic differences of ESCC were also evaluated. RESULTS Loss of esophageal wall thickness and deep ulceration were morphologic characteristics of ESCC after radiotherapy. Tumor vessel density was reduced and GLUT1 expression was greater in the ESCC after radiotherapy than in those without treatment. Tumor vessel density was similar for both preoperative and radical radiotherapy samples, while GLUT1 expression tended to be greater in the latter than in the former. The expression of MIB-1 and p53 did not show any significant difference between ESCC with or without radiotherapy. CONCLUSIONS Reduced vessel density and increased GLUT1 expression suggested tumor hypoxia for ESCC occurred after radiotherapy. Tumor hypoxia would induce ulcerative and invasive growth, which is a great obstacle to clinical treatment of residual or relapse ESCC after radiotherapy.

Abstract
OBJECTIVE The purpose of this experimental study was to investigate whether aortic stent grafting can be applied to the treatment of an esophageal cancer involving the thoracic aorta. METHODS The canine thoracic aorta was partially resected without aorta being clamped after emplacement of an endovascular stent graft. Study I; The aortic whole layer of 1 cm in length and 1/4 of the circumference was resected and was covered by a free fascia patch of the abdominal rectal muscle immediately after stent graft placement. Study II; The aortic adventitia and the outer half of the media of the same size was resected on day 3, 7, 14, 21, and on day 28, after the stent graft placement. The resected portion was covered by the free fascia patch in half experimental dogs, and was uncovered in the others. Study III; The aortic adventitia and the outer half of the media of 1 cm in length and 1/2 of the circumference was resected and was uncovered on day 7 after stent graft placement. Histological examinations were performed on day 28 and at one year after aortic resection. RESULTS The aortic wall could be resected in all cases with no complication, except in resection of 1/2 the circumference where the aorta had become narrow. There was no difference in healing of the resected portion of the aorta between with and without fascia covering. CONCLUSION An aortic endovascular stent graft could be applied to surgery for an esophageal cancer involving the aorta.

Abstract
BACKGROUND The caudal spread of esophageal squamous cell carcinoma (ESCC) frequently involves the stomach. An extended surgical treatment may provide a tumor-free margin; however, its clinical benefit has not been elucidated. METHODS Sixty-three of 582 patients with ESCC (11%) had massive gastric involvement and underwent esophagectomy with combined resection of the stomach and other organs. The mode of gastric involvement was classified as direct invasion from primary tumor (PT invasion) or invasion from metastatic lymph nodes (LN invasion). RESULTS In addition to the removal of either the proximal (83%) or the whole (17%) stomach, 46 patients (73%) underwent the combined resection of adjacent organs, including the diaphragm, pancreas, liver, lung, and pericardium. This surgical treatment resulted in a high rate (83%) of curative resection and a low rate (8%) of operative mortality. Postoperative survival rates were 53%, 33%, and 25% at 1, 2, and 5 years, respectively. The first tumor recurrence was frequently in the abdominal paraaortic lymph nodes (41%) and the liver (28%), followed by the mediastinal lymph nodes, local recurrence, the lung, and other organs. The mode of gastric involvement strongly affected clinical outcome, with a 5-year survival rate of 36% for those with PT invasion but of only 7% with LN invasion (P <.0086). No significant difference was seen in the number and location of metastatic lymph nodes between the 2 groups; however, the size of the largest metastatic lymph node was significantly smaller with PT invasion than with LN invasion (12 mm vs 37 mm in diameter; P <.0001). CONCLUSION Surgical treatment of ESCC involving the stomach was considered safe and successful. A favorable prognosis can be expected for gastric invasion from the primary tumor but not from metastatic lymph nodes.
