Abstract
Oesophageal carcinoma ranks the sixth leading cause of cancer death and affected 544,000 - 604,000 people in 2020. Patients often presented with a poor cancer prognosis with a low survival rate of 15-25%. Depending upon the cell type, oesophageal carcinoma is categorised into oesophageal squamous cell carcinoma (ESCC) and oesophageal adenocarcinoma (EAC). ESCC is predominantly reported in developing countries, while EAC is more common in developed countries. Aside from the presence of exogenous co-factors, such as cigarette smoking, alcohol consumption, obesity, gastroesophageal reflux disease (GERD); infection with oncogenic viruses is suspected to be one of the major factors contributing to EC development. Oncogenic viruses, including human papillomavirus (HPV), Epstein Barr virus (EBV), Cytomegalovirus (CMV) and Herpes Simplex Virus (HSV) have been detected in various proportions of EC samples. Nonetheless, their aetiological roles in EC remain debatable. In this review, we garnered previous studies that focus on the association between oncogenic viruses and EC. Among these oncogenic viruses, HPV appears to have a stronger association with EC than the others. In addition, we also discuss the pros and cons of the treatment regimens to treat EC patients, including immunotherapy, chemo- and chemoradiotherapy, and their efficacy.

Abstract
Neoadjuvant chemotherapy (NAC) followed by esophagectomy is considered the standard treatment for resectable advanced esophageal squamous cell carcinoma in Japan. The purpose of this study was to identify the risk factors for residual tumors in surgery following NAC. We herein described risk factors for residual tumors in surgery following neoadjuvant chemotherapy for thoracic esophageal cancer. We reviewed the medical records of patients in our institution selected by using the following criteria: (1) pathologically confirmed squamous cell carcinoma or adenosquamous carcinoma before treatment; (2) cT1 to cT3; and (3) receipt of thoracotomy performed between 2007 and 2010 with the intention of curative resection after NAC composed of 5-fluorouracil plus cisplatin. The patients were divided into the complete resection group (R0 group), and the macroscopic or microscopic residual tumor group [R(+) group]. A total of 88 patients were eligible (R0, 70 patients; R1, 9 patients; R2, 7 patients; and not resected, 2 patients). There were more cT3 cancers and clinical node-positive diseases in the R(+) group than in the R0 group. Multivariate analysis identified tumor depth (cT3) and tumor location (above the carina) as risk factors for residual tumor. Patients with cT3 esophageal cancer above the carina have a high risk of residual tumor in esophagectomy following NAC. In these patients, more intensive preoperative therapy will be required.

Abstract
AIM Combination therapies of cisplatin with 5-FU (PF) are an effective solution and have been widely used for the treatment of various categories of cancer including anal, gastrointestinal, and oral cancer, as well as head and neck tumors. The effects of combined PF treatment on vital intracellular signalling pathways in nontargeted cells remain unclear. The aim of this study is to explain the possible mechanisms by which combined PF treatment results in retinal toxicity and to investigate the effects of PF on important vital signalling pathways in ARPE 19 retinal pigmented epithelial cells. MATERIALS AND METHODS We analysed the cellular and molecular effects of PF on cell viability, oxidative stress, gene repair response, and induction of apoptosis in ARPE 19 cells using molecular probe fluorescent staining, cell cytometer, RAPD, qRT-PCR, and western blot assays. RESULTS We determined that PF causes excessive generation of reactive oxygen species (ROS) and prevents ROS scavenging by suppressing antioxidant systems. We found induction of DNA damage, particularly mismatch and double strand break repair, in ARPE 19 cells treated with PF. In this study, PF also induced both the intrinsic apoptosis pathway and death receptor signalling in ARPE 19 cells. CONCLUSIONS Our data proved that PF causes cytotoxicity and genotoxicity, at both the cellular and molecular levels, in ARPE 19 cells following particularly prolonged treatment (48 h). Additionally, our results suggest key molecular signals for prevention strategies that can be developed to reduce the severe side effects of PF chemotherapy.

Clinical utility of a novel hybrid position combining the left lateral decubitus and prone positions during thoracoscopic esophagectomy. World J Surg 2014; 38:410-8. [PMID: 24101023 DOI: 10.1007/s00268-013-2258-4] [Citation(s) in RCA: 36] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/13/2022]
Abstract
BACKGROUND We developed a hybrid of the prone and left lateral decubitus positions for thoracoscopic esophagectomy (TE) in 2009. This study aimed to evaluate the feasibility of applying this novel TE position. METHODS We retrospectively analyzed 78 patients who underwent TE at our institution between 2005 and 2010. Altogether, 33 patients underwent TE in the left lateral decubitus position (LD-TE) from 2005 to 2008, and 45 underwent TE in the hybrid position (hybrid-TE) from 2009 to 2010. Radical lymphadenectomy along the bilateral recurrent laryngeal nerves was performed in both groups. The thoracic duct was preserved in the LD-TE group and resected in the hybrid-TE group. In the LD-TE group, all thoracic procedures were performed with the patient in the left lateral decubitus position. In the hybrid-TE group, the upper mediastinal procedure was performed with the patient in the left lateral decubitus position, and procedures at the middle and lower mediastinum were performed with the patient in the prone position under CO2 pneumothorax. RESULTS Hybrid-TE was associated with increased operating time. The number of harvested mediastinal nodes and the PaO2/FiO2 ratio on postoperative day 1 were both greater in this position. Although vocal cord palsy was observed more frequently in the hybrid-TE group, there was no significant difference in the rate of other complications or in-hospital mortality between the two groups. CONCLUSIONS The novel hybrid position is believed feasible for use during TE. We believe that this position facilitates a more radical mediastinal lymphadenectomy with minimal intraoperative pulmonary damage.

Abstract
BACKGROUND There is a consensus that neoadjuvant therapy is an essential component of treatment for resectable advanced esophageal cancer. The aim of this study was to evaluate the efficacy of preoperative docetaxel/cisplatin/5-fluorouracil (DCF) followed by esophagectomy for patients with node-positive esophageal cancer using a prospective database. METHODS Fifty-five consecutive patients with resectable node-positive esophageal cancer were treated with preoperative DCF between August 2008 and December 2010. Of these patients, 54 completed 2 courses of DCF, and 50 underwent esophagectomy after the planned chemotherapy. Clinical and pathologic responses to DCF were investigated, as was patient prognosis. Cox proportional hazard regression was used to determine factors that independently affected recurrence. RESULTS Complete response, partial response, stable disease, and progressive disease were observed in 5, 24, 24, and 2 patients, respectively. Overall, the clinical response rate was 53 %. Pathologic complete response was achieved in 6 cases (12 %), and the overall pathologic response rate was 36 %. Downstaging was observed in 23 cases (46 %). Two-year overall and disease-free survival rates were 78 and 56 %, respectively. Multivariate analysis revealed that residual tumor [R1/2; hazard ratio (HR) 5.21, 95 % confidence interval (CI) 1.64-17.2], pathologic poor response (grade 1a; HR 3.08, 95 % CI 1.08-11.1), and ypN (M1Lym; HR 13.3, 95 % CI 2.06-116) were independent predictors of recurrence. CONCLUSIONS DCF has strong antitumor activity for esophageal cancer and may confer survival benefits when used as preoperative chemotherapy.

Abstract
Background The polycomb group (PcG) family BMI1, acting downstream of the hedgehog (Hh) pathway, plays an essential role in the self-renewal of haematopoietic, neural, and intestinal stem cells, and is dysregulated in many types of cancer. Our recent report has demonstrated that Hh signalling activation can predict very earlier relapse of oesophageal cancers. As data were not available on the clinical role of BMI1 expression in oesophageal cancers after chemoradiotherapy (CRT), we analysed whether it could be also used to predict disease progression and prognosis in oesophageal cancer patients undergoing trimodality therapy of preoperative CRT and oesophagectomy. Methods Expressions of BMI1 and p16INK4A, a downstream target of PcG, were analysed in 78 patients with histologically confirmed oesophageal squamous cell carcinoma (ESCC) after preoperative CRT by immunohistochemical staining. The association of BMI1 and p16INK4A expression with clinicopathologic characteristics was analysed by χ2-test. Survival analysis was carried out by the log-rank test using Kaplan-Meier method. Results Among 78 ESCC patients, 24 patients (30.8%) showed BMI1 positivity, mainly localised in the nuclei of tumour cells. Patients harbouring BMI1-positive tumour cells showed significantly poorer prognoses than those without such cells or residual tumours (mean disease-free survival (DFS) time 16.8 vs 71.2 months; 3-yr DFS 13.3% vs 49.9%, P=0.002; mean OS time 21.8 vs 76.6 months; 3-yr OS 16.2% vs 54.9%, P=0.0005). There was no significant correlation between p16INK4A expression and BMI1 expression. Conclusions Our study shows that BMI1 expression is a predictor of early relapse and poor prognosis in ESCC after CRT. These findings suggest that BMI1 signal activation might be involved in promoting cancer regrowth and progression after CRT, and might be indicative of emergence of ‘more aggressive’ cancer progenitor cells.

Abstract
The HyperEye Medical System is a newly developed device that allows for the visualization of the fluorescent image of indocyanine green enhanced by near-infrared light among the surrounding vivid color images. We recently applied this system to confirm the blood flow of an esophageal substitute, and for sentinel node navigation during esophagectomy. Five consecutive patients with thoracic esophageal cancer who underwent a subtotal esophagectomy between June 2010 and May 2011 were enrolled in the study. The esophageal substitute used for reconstruction was the stomach and ileocecum in four and one cases, respectively. In all cases with a reconstructive stomach, fine arterial blood flow and venous perfusion were observed. The blood flow of the reconstructive colon was poor before microvascular anastomosis, however, it dramatically increased after anastomosis. Concerning the sentinel node navigation, the fluorescence of lymph nodes, lymphatic vessels, and the tumor site were detected. The postoperative courses of all cases were uneventful, with no mortalities or anastomotic leakage occurring.

Abstract
BACKGROUND An elevation in the neutrophil-to-lymphocyte ratio (NLR) has been shown to be associated with a poorer prognosis in patients with various tumors. The aim of this retrospective study was to clarify the correlation of the pretherapeutic NLR with the prognostic value of the pathologic response to neoadjuvant chemotherapy (NAC) in patients with advanced esophageal cancer. METHODS This study was a retrospective review of 83 patients undergoing NAC for advanced esophageal cancer following esophagectomy. The NLR was measured before NAC, and the pathologic responses to NAC were evaluated. RESULTS A comparison was performed for those whose pathology responded (responders) (G3/G2/G1b) and nonresponders (G1a/G0). In a univariate analysis, the cStage (P = 0.005), cN (P = 0.0001), and NLR (P = 0.005) were statistically significant parameters. A multivariate analysis revealed that the factors independently associated with pathologic responses were the pretreatment NLR (<2.2/≥2.2) (P = 0.043) and lymph nodes metastasis (P = 0.002). The pretreatment NLR (<2.2/≥2.2) was found to be a statistically significant useful predictive marker for a pathologic response (P = 0.001). The pathologic response rates were 56% in the patients with an NLR <2.2 and 21% in patients with an NLR of ≥2.2. CONCLUSIONS Our study is the first to demonstrate that the pretherapeutic NLR can be used as a predictor for chemosensitivity of thoracic esophageal cancer. Preoperative evaluation based on the clinical N stage and NLR may be easily used in routine clinical practice.

Abstract
Patients who have received subtotal esophagectomy for thoracic esophageal cancer must be closely monitored for second primary malignancies. The purpose of this study is to review and assess patients who developed a second primary esophageal cancer in the residual cervical esophagus. Between 1996 and 2010, 10 patients were diagnosed in our hospital with esophageal squamous cell cancer in the residual cervical esophagus after undergoing thoracic esophagectomy and were treated with endoscopic or surgical resection. Data from these patients were reviewed retrospectively. Seven of the 10 patients (70%) had multiple primary carcinoma lesions at the time of their esophagectomy. A second primary cancer in the residual cervical esophagus was detected in eight patients during follow-up endoscopic examinations while the patients were still asymptomatic. Seven of the patients underwent endoscopic resection for a superficial cancer. None of those patients experienced any complications, and all are currently alive and cancer-free. The remaining three patients underwent resection of the cervical esophagus with regional lymph node dissection. Two of those patients experienced severe complications; one subsequently died (hospital death) from pneumonia, 12 months after surgery, while the other died from recurrence of his cancer. The third patient is alive and cancer-free. Early detection of a second primary malignancy in the residual cervical esophagus followed by endoscopic resection is the best treatment strategy for patients who previously received subtotal esophagectomy for thoracic esophageal cancer. Surgical resection puts patients at high risk of mortality or morbidity.

Abstract
Neoadjuvant therapy-induced immunological deterioration may be a key factor in postoperative morbidity in patients with esophageal cancer. This study aimed to determine the effects of perioperative feeding with an immuno-enhanced diet on immune competence in patients treated with neoadjuvant therapy followed by surgery. Because an immuno-enhanced diet that contained several antioxidants was used, perioperative oxidative stress and the effects of the immuno-enhanced diet on this stress were also investigated. Of 39 patients with esophageal cancer who underwent similar surgical procedures, 26 patients who received chemotherapy or chemoradiation therapy before surgery were randomly divided into two groups: group 1 (n= 14) was given an immuno-enhanced diet for 5 days before surgery, and group 2 (n= 12) received no enteral feeding products before surgery. Group 3 (n= 13) consisted of patients that did not receive neoadjuvant therapy and received no enteral feeding products before surgery. Several markers for coagulation and fibrinolysis were determined and immunological assessments were performed for each patient. To measure reactive oxygen metabolites and the total antioxidant capacity, diacron-reactive oxygen metabolites (d-ROMs) and OXY-adsorbent tests were performed using a free radical elective evaluator. Significant depression in lymphocyte numbers was observed in groups 1 and 2 before and early after surgery as compared to group 3. Numbers of B cells, CD4/CD8 ratio, and phytohemagglutinin-induced lymphocyte transformation tests were also significantly decreased in groups 1 and 2 on postoperative day 1. Fibrin and fibrinogen degradation products were significantly elevated in group 2 compared to group 1. d-ROMs and OXY-adsorbent test values were elevated before surgery and were decreased transiently early after surgery. Compared to groups 2 and 3, d-ROMs values were significantly lower in group 1 patients throughout the postoperative period, while OXY-adsorbent test values were significantly higher in group 2 patients. Oxidative index was significantly suppressed in group 1 compared to group 3. No significant intergroup differences were observed with regard to morbidity after surgery. Although the baseline levels of immunological function might have been different because of less-advanced cancer stages in group 3, neoadjuvant therapy significantly affected several immunological parameters. Preoperative administration of an immuno-enhanced diet did not significantly prevent neoadjuvant therapy-induced immunological deterioration prior to esophageal cancer surgery. Patients with esophageal cancer had elevated levels of oxidant and antioxidant activities before surgery, which were transiently decreased early after surgery. Although the underlying mechanisms for these perioperative changes are unclear, this study showed that an immuno-enhanced diet containing several antioxidants may reduce oxidative stress following esophageal cancer surgery. After these mechanisms are studied further, oxidative stress control may become another tool for perioperative management to reduce morbidity after esophageal cancer surgery.

Abstract
Neoadjuvant chemotherapy for resectable esophageal carcinoma has been a focus of study, but no agreement has been reached on clinical randomized controlled trials and relevant systematic evaluation. The purpose of this study was to perform a meta-analysis on published randomized controlled trials (RCTs) that compared neoadjuvant chemotherapy and surgery with surgery alone for resectable esophageal carcinoma. Medline and manual searches was conducted in PubMed, ASCO (American Society of Clinical Oncology) meeting summary, Embase, the Cochrane Library (up to October 2010), Chinese Biomedical Literature Database, China National Knowledge Infrastructure, VIP Database, Wanfang Database. The selection contents were to identify all published and unpublished RCTs that compared neoadjuvant chemotherapy and surgery with surgery alone for resectable esophageal carcinoma. Sixteen RCTs which included 2,594 patients were selected. The risk ratio (RR) (95% confidence interval [CI]; P value), expressed as neoadjuvant chemotherapy and surgery versus surgery alone (treatment versus control), was 1.02 (0.95, 1.10; P=0.54) for 1-year survival, 1.29 (1.13, 1.47; P=0.0001) for 3-year survival, 1.31 (1.13, 1.51; P=0.0003) for 5-year survival, 1.00 (0.95, 1.04; P= 0.85) for rate of resection and 0.89 (0.64, 1.23; P=0.48) for operative mortality. The results showed that neoadjuvant chemotherapy for resectable esophageal carcinoma can raise the overall survival rate of patients with esophageal carcinoma, but it does not affect treatment-related mortality.

Abstract
BACKGROUND The human epidermal growth factor receptor (HER) family, Ki-67 and p53 are important biomarkers for several malignancies. However, few studies have examined the role of these in prognosis and therapeutic sensitivity of esophageal squamous cell carcinoma (ESCC). The efficacy of triple-drug combination therapy with docetaxel, fluorouracil and cisplatin has recently been expected for ESCC. METHODS Subjects comprised 142 patients with ESCC who underwent operation (OP group, n = 54), neoadjuvant chemotherapy with docetaxel, fluorouracil, and cisplatin (DFP therapy) followed by operation (NAC group, n = 37) or initial systemic DFP therapy (CT group, n = 51) between January 2004 and December 2010. Immunohistochemical expressions of epidermal growth factor receptor (EGFR), HER2, HER3, Ki-67, and p53 were evaluated and compared with prognosis and sensitivity to DFP therapy. RESULTS Positive correlations existed between EGFR, HER2, and HER3 expressions. In the OP group, EGFR was independently associated with postoperative recurrence in multivariate analysis (P = .036). In the NAC group, EGFR correlated with pathological response to DFP therapy (P = .004). In the CT group, EGFR, HER2, and HER3 correlated with clinical response to DFP therapy and EGFR was independently associated with favorable prognosis in multivariate analysis (P = .022). CONCLUSION EGFR represents a predictor of postoperative recurrence and sensitivity to triple-drug combination therapy including a taxane. EGFR-positive patients may show improved prognosis with taxane combination chemotherapy and molecular targeted therapy for HER family members.

Abstract
BACKGROUND The Japan Clinical Oncology Group (JCOG) 9907 trial has changed the standard of care for advanced thoracic oesophageal cancer in Japan from postoperative chemotherapy to preoperative chemotherapy. The impact of preoperative chemotherapy on the risk of developing postoperative complications remains controversial. This article reports the safety analysis of JCOG9907, focusing on risk factors for postoperative complications. METHODS Patients with potentially resectable advanced thoracic oesophageal squamous cell carcinoma were randomized to either postoperative or preoperative chemotherapy followed by transthoracic oesophagectomy with D2-3 lymphadenectomy. Chemotherapy consisted of two cycles of cisplatin and 5-fluorouracil. Clinical baseline data, intraoperative complications, postoperative complications and in-hospital mortality, collected on the case report forms in a predetermined format, were analysed. Univariable and multivariable analyses were used to explore the risk of postoperative complications in relation to treatment group, age, sex, tumour depth, nodal metastasis, stage and location. RESULTS Of 330 patients randomized, 166 were assigned to receive postoperative chemotherapy and 164 preoperative chemotherapy; 162 and 154 patients respectively underwent surgery. The incidence of intraoperative complications, postoperative complications and in-hospital mortality was similarly low in both groups. Multivariable analysis showed that age, sex and tumour location were independently associated with an increase in postoperative complications, but preoperative chemotherapy was not. CONCLUSION Preoperative chemotherapy does not increase the risk of complications or hospital mortality after surgery for advanced thoracic oesophageal cancer.

Abstract
The revision of the TNM Classification of Malignant Tumors, 7th Edition, suggests the lymph node (LN) status to be the most significant risk factor in esophageal cancer. This article reviews the current status of LNs as indicators of prognosis. The significance of the number of metastatic LNs, the number of resected LNs, and a novel index, the "LN ratio" (metastatic LNs/removed LNs) in patients with esophageal cancer, were reviewed. The number of metastatic LNs independently predicted the prognosis of both overall survival and relapse-free survival. The number of positive LNs was also the best predictive marker of survival. Furthermore, overall survival significantly depended on the number of surgically removed LNs, and the LN ratio closely correlated with survival. The LN status is considered to be the most significant information that can be used to predict the prognosis. However, there are many issues that still need to be resolved. Better knowledge of the N-status is therefore needed to effectively utilize this information. Further research should focus on the N-status of patients with esophageal cancer.

Abstract
BACKGROUND This study aimed to assess treatment outcome and factors influencing survival after lymph node recurrence of thoracic esophageal squamous cell carcinoma (SCC) after curative resection. METHODS A total of 207 patients who underwent curative resection of thoracic esophageal SCC between March 1999 and March 2009 were retrospectively analyzed. Of these, lymph node recurrence was observed in 45 (21.7%) patients. Twenty-nine patients received intensive treatment (radiation therapy, chemoradiotherapy, or lymphadenectomy) directed at recurrent nodes, 9 patients received chemotherapy, and 7 patients received best supportive care (BSC). Treatment outcome and prognostic factors of these patients were investigated. RESULTS Patients who received intensive treatment had significantly higher survival rates after recurrence than those who received chemotherapy or BSC (P = 0.0049 and 0.0004, respectively). In univariate analysis of survival after recurrence, the number of recurrent nodes (a single node or multiple nodes), the region of recurrent nodes (limited to a single region or extended to multiple regions), and the presence of simultaneous organ recurrence (present or absent) were prognostic factors (P = 0.0004, 0.0017, and <0.0001, respectively). Multivariate analysis demonstrated that the region of recurrent nodes and simultaneous organ recurrence were independent prognostic factors (P = 0.0396 and 0.0006, respectively). CONCLUSIONS Our findings suggest that the region of recurrent nodes (limited to a single region or extended to multiple regions) and simultaneous organ recurrence are factors influencing survival after lymph node recurrence of thoracic esophageal SCC after curative resection.

Predicting the effects of chemoradiotherapy for squamous cell carcinoma of the esophagus by induction chemotherapy response assessed by positron emission tomography: toward PET-response-guided selection of chemoradiotherapy or esophagectomy. Int J Clin Oncol 2011; 17:225-32.

Abstract
BACKGROUND We have developed a treatment protocol for esophageal cancer involving a single course of induction chemotherapy followed by chemoradiotherapy. This study aimed to determine if it was possible to predict the effects of chemoradiotherapy on the basis of the response to induction chemotherapy, assessed by positron emission tomography (PET). METHODS Sixteen patients with Stage II-IVA esophageal cancer were treated using this protocol from April 2007 to July 2010. Chemotherapy involved a fluorouracil and platinum-based combination regimen. All patients received PET scans before and 12-24 days after the beginning of induction chemotherapy. Associations between the response to induction chemotherapy assessed by PET and the effects of chemoradiotherapy were evaluated. RESULTS Induction chemotherapy followed by chemoradiotherapy resulted in complete response (CR) in 10 of the 16 patients. The reduction in maximum standardized uptake value (SUV(max)) was 58 ± 12% in patients with CR (n = 10), compared with 14 ± 16% in patients without CR (n = 6) (P < 0.0001). Using a cut-off value of 55% for SUV(max) reduction rate, eight of 10 cancers with CR and six of six cancers without CR were correctly identified, providing a sensitivity and specificity of 80 and 100%, respectively. The overall 1-year survival rates for patients with an SUV(max) reduction rate >55% (responders) were 100%, compared with 60% for patients with an SUV(max) reduction rate ≤55% (non-responders), respectively. CONCLUSIONS The response to a single course of induction therapy assessed by PET was significantly associated with the effects of chemoradiotherapy.

Abstract
BACKGROUND Extended radical esophagectomy with three-field lymph node dissection (3-FLD) has offered significant survival benefit, but some patients still suffer from early recurrence and die within 1 year after surgery. The purpose of this study was to identify the risk factors that influence early death due to cancer recurrence after extended radical esophagectomy with 3-FLD. METHODS A consecutive series of 276 patients who underwent extended radical esophagectomy with 3-FLD was retrospectively reviewed. Excluding patients who underwent incomplete resection or died of other diseases within 1 year, we compared the clinicopathological characteristics between 203 patients who survived more than 1 year (1-year survival group) and 27 who died of cancer recurrence within 1 year (early-death group) by univariate and multivariate analysis. RESULTS Sixty-six patients (32.5%) had recurrent disease in the 1-year survival group. Hematogenous recurrences were more frequent in the early-death group than in the 1-year survival group (41% vs. 26%, respectively, p = 0.0481). There was a significant difference in nodal status, number of metastatic nodes, pathological stage, vessel invasion, and intramural metastasis, and there was borderline significance in the difference of depth of invasion and histological type between the two groups by univariate analysis. Multivariate analysis demonstrated that intramural metastasis was an independent risk factor. CONCLUSIONS Patients with intramural metastasis have a significant risk of early death even after extended radical esophagectomy with 3-FLD; however, it remains unknown whether surgical intervention can play a significant role for these patients.

Abstract
We have reviewed the pivotal presentations rcelated to colorectal cancer (CRC) and other gastrointestinal malignancies from 2008 annual meeting of the American Society of Clinical Oncology (ASCO). We have discussed the scientific findings and the impact on practice guidelines and ongoing clinical trials. The report on KRAS status in patients with metastatic CRC receiving epidermal growth factor receptor (EGFR) targeted antibody treatment has led to a change in National Comprehensive Cancer Network guideline that recommends only patients with wild-type KRAS tumor should receive this treatment. The results of double biologics (bevacizumab and anti-EGFR antibody) plus chemotherapy as first-line treatment in patients with metastatic CRC has shown a worse outcome than bevacizumab-based regimen. Microsatellite Instability has again been confirmed to be an important predictor in patients with stage II colon cancer receiving adjuvant treatment. Adjuvant gemcitabine therapy for pancreatic cancer was investigated by the CONKO-001 study; this resulted in superior survival as compared with observation and can be regarded as an acceptable option, without the addition of radiotherapy. The addition of bevacizumab to gemcitabine and erlotinib was not supior to gemcitabine and erlotinib for advanced disease. Second-line therapy for advanced pancreatic cancer with 5-fluorouracil and oxaliplatin resulted in a survival benefit. Irinotecan plus cisplatin and paclitaxel plus cisplatin result in similar survival when combined with radiotherapy for esophageal cancer. The novel fluoropyrimidine S1 appears to be active in gastric cancer, as a single agent or as combination therapy. Adjuvant intraperitoneal mitomycin-C may decrease the incidence of peritoneal recurrence of gastric cancer. Sorafenib is an effective agent in Asian patients with hepatocellular carcinoma secondary to hepatitis B; its utility in child's B cirrhosis remains to be proven. Sunitinib is also an active agent in hepatocellular carcinoma, and may represent an alterative to sorafenib for advanced disease. These and other important presentations from the 2008 ASCO annual meeting are discussed in this article.

Abstract
An esophagectomy with three-field lymph node dissection is the standard therapy for esophageal cancer in many countries, including Japan. However, the results of esophagectomy are still unsatisfactory in comparison to the results of surgical treatment for gastric cancer or colon cancer. On the other hand, definitive chemoradiation therapy has recently shown progress as a treatment modality for resectable esophageal cancer, with data indicating the potential efficacy of combination therapy with chemoradiation and an esophagectomy. In fact, preoperative chemoradiotherapy for resectable esophageal cancer is becoming a standard therapy in Europe and North America. The latest metaanalysis concerning neoadjuvant chemoradiotherapy for resectable esophageal cancer concluded that a significant survival benefit was evident with preoperative chemoradiotherapy. However, there are still no supportive data for neoadjuvant chemoradiation and surgery from a well-designed large-scale randomized control trial (RCT). A well-designed large-scale RCT is needed to determine the utility of neoadjuvant chemoradiation. Future trials based on precise diagnosis and surgical procedures are required for the adequate interpretation of the results of treatment for resectable esophageal cancer. Of course, quality control of the operation is a very important factor, because operative mortality influences these results.
