Cardiac metastases.	We report a case of esophageal cancer with symptomatic metastases to the heart; the patient was treated with short-course radiotherapy with good symptomatic relief. We reviewed the current literature regarding the epidemiology, clinical presentation, diagnostic tools, treatment modalities, and the prognosis of cardiac metastases. In this report we summarize the most recent autopsy studies (published between 1975 and 2007), in which we found an autopsy incidence of cardiac metastases of 2.3% among the general population, while the incidence among autopsies of cancer patients was 7.1%. Therefore, we share the opinion with others that there has been an increase in the incidence of cardiac metastases among cancer patients diagnosed after 1970, in comparison with the reported incidences in older series before 1970 (7.1% vs 3.8%; Kruskal-Wallis rank test; P = 0.039). Special attention was given to the role of radiotherapy in the management of cardiac metastases.	esophagus
Novel therapeutic strategies for treating esophageal adenocarcinoma: the potential of dendritic cell immunotherapy and combinatorial regimens.	Esophageal adenocarcinoma (EAC) is an extremely aggressive disease with an overall 5 years survival rate of less than 20%. Current treatments, such as surgery, or chemo- and radiotherapy have only little effect on survival. Attempts to combine these treatment modalities were only limited successful with marginal improvement of prognosis. Therefore, novel treatment strategies are urgently needed. In a previous study we demonstrated that dendritic cell (DC) immunotherapy may be an attractive and promising approach to treat EAC. Although potent immune responses can be raised by DC therapy, there are several concerns about the immunosuppressive microenvironment that characterizes these cancers, which may inhibit an effective immune response. Here a general overview is given of the current management of EAC and immunotherapies. More specific focus is on the EAC tumor microenvironment, and several potential combinatorial strategies that can be explored for improving treatment of EAC.	esophagus
Phase II trial of neoadjuvant cisplatin, 5-fluorouracil and interferon-alpha in operable squamous cell carcinoma of the esophagus.	BACKGROUND: The combination of 5-fluorouracil (5-FU), cisplatin and interferon (IFN)-alpha was found to result in a high response rate in advanced esophageal squamous cell carcinoma (SCC). METHODS: Resectable cases of esophageal SCC were treated with 3 cycles of chemotherapy consisting of cisplatin 70 mg/m(2) i.v. on day 1, 5-FU 500 mg/m(2)/day i.v. as a continuous infusion on days 1-5 and IFN-alpha 4 million units/m(2)/day s.c. on days 1-5. Cycles were repeated every 21 days. Esophagectomy was performed 3-5 weeks after the 3rd cycle of chemotherapy. RESULTS: Thirty patients were enrolled in the trial. Toxic death was observed in 1 patient because of esophageal perforation. Pathologically, complete response was observed in 4 of 23 patients who had esophagectomy. At a median follow-up period of 21.4 months, median progression-free survival was 11.5 months and median overall survival was 26.3 months. CONCLUSION: This regimen has substantial activity in localized SCC of the esophagus with encouraging survival duration.	esophagus
Adenocarcinomas of the esophagus: response to chemoradiotherapy is associated with decrease of metabolic tumor volume as measured on PET-CT. Comparison to histopathologic and clinical response evaluation.	PURPOSE: We determined whether evaluation of treatment response is feasible by measuring metabolic tumor volume parameters on 18F-FDG (Fluorodeoxyglucose) PET-CT (Positron emission tomography-Computed tomography). We compared the response evaluation based on metabolic tumor volume parameters to a histopathologic and clinical response evaluation (clinical response criteria: RECIST criteria=Response evaluation criteria in solid tumors, and WHO criteria=World health organization). PATIENTS AND METHODS: A total of 51 study subjects with adenocarcinomas (Type I due to Siewert classification) of the esophagus underwent PET-CT scans before and after neoadjuvant chemoradiotherapy. Tumor volume, maximum and mean standardized uptake values (SUV) were assessed before and after chemoradiotherapy. Furthermore, the total lesion glycolysis (TLG) was calculated by multiplying the tumor volume by the mean SUV of the volume. Clinical response evaluation was performed with endoscopic ultrasound and CT using RECIST and WHO criteria. The reference standard for treatment response was the postsurgical histopathology. RESULTS: The decrease of tumor volume between the pre- and post-treatment PET-CT scans was a better predictor of histopathologic response and survival than the decrease of the SUV and of the clinical response evaluation based on RECIST and WHO criteria. The highest accuracy, however, was achieved when using the TLG for the identification of treatment responders. A decrease of the TLG by > 78% between pre- and post-therapy scans predicted histopathologic response with a sensitivity and specificity of 91% and 93%, respectively. CONCLUSIONS: Tumor volume and TLG can be used to assess treatment response and survival in patients with esophageal adenocarcinoma.	esophagus
Incidence of adenocarcinoma of the esophagus among white Americans by sex, stage, and age.	Rapid increases in the incidence of adenocarcinoma of the esophagus have been reported among white men. We further explored the temporal patterns of this disease among white individuals by sex, stage, and age by use of data from the Surveillance, Epidemiology, and End Results program. We identified 22,759 patients from January 1, 1975, through December 31, 2004, with esophageal cancer, of whom 9526 were diagnosed with adenocarcinoma of the esophagus. Among white men, increases in the incidence of esophageal cancer were largely attributed to a 463% increase in the incidence of adenocarcinoma over this time period, from 1.01 per 100,000 person-years (95% confidence interval [CI] = 0.90 to 1.13) in 1975-1979 to 5.69 per 100,000 person-years (95% CI = 5.47 to 5.91) in 2000-2004. A similar rapid increase was also apparent among white women, among whom the adenocarcinoma rate increased 335%, from 0.17 (95% CI = 0.13 to 0.21) to 0.74 per 100,000 person-years (95% CI = 0.67 to 0.81), over the same time period. Adenocarcinoma rates rose among white men and women in all stage and age groups, indicating that these increases are real and not an artifact of surveillance.	esophagus
Multicenter phase II study of capecitabine plus oxaliplatin as a first-line therapy in Chinese patients with advanced gastric cancer.	The efficacy of chemotherapy for advanced gastric cancer with palliative intent compared with supportive care alone is now widely accepted. However, the survival advantage is small, and no internationally accepted standard regimen has emerged. This study is performed to evaluate the response rate, time to progression, and safety of the combination of capecitabine (1000 mg/m twice daily, days 1-14) plus oxaliplatin (130 mg/m as a 2-h intravenous infusion on day 1) every 3 weeks, in previously untreated Chinese patients with advanced gastric cancer. Sixty-five (95.6%) of the 68 patients were assessable for response. Three cases of complete response and 34 cases of partial response were confirmed, giving an overall response rate of 54.4% [95% confidence interval (CI), 42.6-66.2%]. The median time to progression and overall survival for all patients were 5.7 months (95% CI, 2.0-8.8 months) and 10.5 months (95% CI, 5.0-15.1 months). The most severe hematologic adverse event was neutropenia, which occurred with grade 3 intensity in three (4.6%) patients and grade 4 in one (1.5%) patient. Thrombocytopenia and leukopenia occurred with grade 3 intensity in five (7.7%) and three (4.6%) patients, respectively. However, no grade 4 thrombocytopenia and leukopenia were observed. Grade 1/2 nausea/vomiting and diarrhea were observed in 33 (50.8%), 17 (26.2%), 26 (40%), 44 (67.7%), and 13 (20%) patients, respectively, and grade 3 nausea/vomiting and diarrhea were observed in one (1.5%) and four (6.2%) patients. Yet, no grade 4 nonhematologic toxicity was observed. Capecitabine/oxaliplatin combination chemotherapy is active in Chinese patients with previously untreated advanced gastric cancer.	esophagus
Cardiogenic shock secondary to Tako-tsubo syndrome after debridement of malignant endobronchial obstruction.	Transient left ventricular (LV) dysfunction syndrome, or Tako-tsubo syndrome, occurs following intense emotional or physical stress and simulates the clinical presentation of an acute myocardial infarction. We report a case of a 77-year-old man with esophageal adenocarcinoma with local invasion of the central airways who underwent rigid bronchoscopy for tumor debridement followed by placement of a stent. Postoperatively, cardiogenic shock developed and echocardiography revealed akinesis of the LV apex with an ejection fraction (EF) of 15%. Emergent coronary angiography revealed no significant coronary artery disease. The patient required intraaortic balloon counterpulsation and pressors. Seventy-two hours later, repeat echocardiography showed an EF of 45% with improvement in apical function, and the patient was discharged home in stable condition shortly thereafter. A 5-month follow-up echocardiogram revealed an EF > 55%, and the patient enjoyed an excellent performance status.	esophagus
Independent lung ventilation combined with HFOV for a patient suffering from tracheo-gastric roll fistula.	This case report describes the difficult respiratory management of an esophageal cancer patient with acute respiratory distress syndrome (ARDS) and systemic inflammatory response syndrome (SIRS) caused by a postoperative tracheogastric roll fistula. A single-lumen tracheal tube could not seal the fistula, and therefore a double-lumen tracheal tube (DLT) for the left side was used. Although the proximal cuff of the DLT failed to seal the fistula, independent lung ventilation (ILV) improved blood gas levels. During right thoracotomy, the left lung was ventilated conventionally with 5 cmH2O positive end-expiratory pressure (PEEP), and in addition, high-frequency oscillation ventilation (HFOV) to the right lung was employed. This combination allowed the maintenance of adequate oxygenation, and the HFOV to the right lung decreased the PaCO2 level during surgery without interruption of the surgical field. These techniques provided the opportunity to successfully remove a necrotic gastric roll and achieve closure of the fistula using an intercostal muscle flap. This report documents and discusses the difficulty of performing appropriate anesthetic management of a patient with these complex complications after esophageal surgery.	esophagus
Vascular and lymphatic properties of the superficial and deep lamina propria in Barrett esophagus.	"A well-known type of mesenchymal/epithelial interaction occurs in Barrett esophagus (BE) characterized by the formation of a new, superficially located, muscularis mucosae (MM), which results in the division of the lamina propria (LP) into a superficial and deep compartment. The vascular and lymphatic properties of these 2 regions of LP are unknown. The risk of metastases of carcinomas that infiltrate these 2 anatomic areas also remains unclear. The aim of this study was to evaluate the density of blood vessels and lymphatic spaces within the superficial and deep LP and submucosa in patients with BE, and to compare the results to normal squamous-lined esophagus. Thirty esophago-gastrectomy specimens were stained immunohistochemically with CD31 (stains blood vessel and lymphatic endothelium) and D2-40 (stains lymphatic endothelium only). The density of CD31+ blood and lymphatic vessels (per 20 x field) in BE (superficial LP=37 and deep LP=38) was significantly lower compared with the LP of squamous-lined esophagus (68; P<0.001). However, the total number of blood and lymphatic vessels in the superficial and deep LP in BE was statistically similar to the LP of squamous-lined esophagus. The density of CD31+ blood and lymphatic vessels (per 20x field) in the submucosa of BE (21) was not significantly different from the submucosa of squamous-lined esophagus (23; P>0.05). We conclude that in BE, the ""native"" LP in squamous-lined esophagus is separated into 2 LP compartments (superficial and deep) by the formation of a new MM. These findings suggest that carcinomas that invade through the superficial MM into the deep LP should be considered ""intramucosal"" rather than ""submucosal."" Further outcome studies are needed to evaluate the risk of vascular/lymphatic metastasis in BE patients with different levels of LP invasion."	esophagus
Esophageal cancer: epidemiology, pathogenesis and prevention.	Esophageal cancer is highly aggressive and is a common cancer both worldwide and in the US. In the past two decades, the incidence and mortality of esophageal cancer in the US have both increased, where as the incidence and mortality of other cancers have decreased. Although esophageal squamous cell carcinoma and esophageal adenocarcinoma differ in their histology and epidemiologic distribution, some of their risk factors (e.g. dietary deficiencies and tobacco) and underlying mechanisms of carcinogenesis are the same. Intensive research into risk factors combined with the ability to identify precursor lesions (e.g.squamous dysplasia in esophageal squamous cell carcinoma and Barrett's esophagus in esophageal adenocarcinoma) has paved the way for studies of chemoprevention for esophageal cancer, some of which have shown promising results.	esophagus
Quality of Barrett's surveillance in The Netherlands: a standardized review of endoscopy and pathology reports.	OBJECTIVE: The quality of Barrett's surveillance relies on an adequate endoscopic inspection, obtaining a sufficient number of biopsy specimens, good communication of the endoscopic findings to the pathologist, and an accurate description of the histological findings by the pathologist. The aim of this study was to assess the quality of Barrett's surveillance in daily practice in The Netherlands. MATERIALS AND METHODS: A structured scoring list was developed to evaluate systematically the quality of endoscopy and pathology reports. From 15 hospitals, endoscopy reports and corresponding pathology reports were selected randomly and evaluated by two observers. In case of disagreement, the observers re-evaluated the reports in a consensus meeting. RESULTS: One hundred and fifty cases were evaluated. The adherence to current standard biopsy protocols (four quadrant biopsies every 2 cm) decreased with increasing Barrett's length: 0-5 cm: 79%; 5-10 cm: 50%; 10-15 cm: 30%. The indication for the endoscopy was mentioned in 28% of the pathology reports, in 4% the presence/absence of oesophagitis was communicated, and in 19% the location and/or aetiology of biopsies was described. The presence/absence of dysplasia was mentioned in 93% of pathology reports. CONCLUSION: Endoscopy reports and pathology reports in current practice do not include all relevant information for an adequate Barrett's surveillance. In short Barrett's oesophagus, the adherence to current standard biopsy protocols is acceptable, but in longer segments (with a higher risk for neoplastic progression) this is clearly insufficient. The communication between endoscopists and pathologist is suboptimal.	esophagus
Acrokeratosis paraneoplastica Bazex syndrome associated with esophageal squamocellular carcinoma.	BACKGROUND: Acrokeratosis paraneoplastica Bazex (APB) is a very rare disease in the group of obligate paraneoplastic dermatoses, associated mostly with squamous cell carcinoma of the upper aerodigestive tract and metastatic cervical lymphadenopathy. The disease is characterized by violaceous erythemosquamous changes on the acral regions. This entity was first reported by Bazex in 1965. About 160 cases have been presented so far. CASE REPORT: We presented a patient with a three-month history of violaceous erythema, edema, erosions and scaling on the acral regions, elbows and knees and severe nail dystrophy. When the diagnosis was established, he did not have any symptom of internal malignancy. Esophagogastroscopy revealed ulcerovegetant lesion of the esophagus, while histology showed squamocellular invasive carcinoma. Surgical tumor removal resulted in significant improvement of skin changes in 15 days. Unfortunately, four months later, extensive skin lesions pointed to metastasis of squamous cell carcinoma. CONCLUSION: Skin changes can precede a few years the first manifestations of neoplasia. The course of the disease in our patient proved that APB is a specific marker of underlying malignancy.	esophagus
Comparison of hand-sewn and stapled in esophagogastric anastomosis after esophageal cancer resection: a prospective randomized study.	OBJECTIVE: Compare the postoperative outcome of the hand-sewn method and the staple method of primary esophagogastric anastomosis after esophagectomy in patients with esophageal carcinoma. The study focused on leakage, stricture rates, operative time, blood loss, and complication. MATERIAL AND METHOD: A prospective randomized trial was undertaken in 117 patients with squamous cell carcinoma of the thoracic esophagus who underwent Ivor-Lewis esophagectomy. Patients were classified according to esophageal size, based on the diameter of the divided esophagus (< or > 30 mm) and then were randomized to have primary anastomosis using either hand-sewn or stapled method. RESULTS: The mean total operating time of esophagectomy when using hand-sewn technique and staple technique were 218.1 +/- 47.8 minutes and 203.7 +/- 23.4 minutes, respectively (p = < 0.001). The mean blood loss in the handsewn group and in the staple group was 864 +/- 346.6 mls and 803 +/- 301.2 mls, respectively (p = 0.02). Anastomotic leakage was 6.7% in the hand-sewn group and 3.4% in the staple group (p = 0.69). Pulmonary and cardiac complications were 13.5% and 16.9% in the hand-sewn group compared with 17.2% and 18.9% in the staple group (p = 0.77, p = 0.96). Anastomotic stricture was found in 10 of 52 patients (19.2%) in the handsewn group and 19 of 52 patients (36.5%) in the staple group (p = 0.08). In the patients with a small esophagus, the stricture rate was significantly lower in the hand-sewn group compared with the staple group (15.2% vs. 38.8%) (p = 0.03). Mortality rate in both groups were not significantly different (11.8% vs. 10.3%) (p = 0.97). CONCLUSION: From the present study, it can be concluded that both hand-sewn method and the staple method in primary esophagogastric anastomosis after esophagectomy in the patients with esophageal carcinoma were safe. The stapled method had a higher incidence of anastomotic stricture especially small esophagus, whereas it consumed less operative time and less blood loss.	esophagus
Poor interobserver agreement in the distinction of high-grade dysplasia and adenocarcinoma in pretreatment Barrett's esophagus biopsies.	OBJECTIVE: Grading Barrett's dysplasia at the lower end of the metaplasia-dysplasia spectrum (negative, indefinite, and low-grade dysplasia) suffers from poor interobserver agreement, even among gastrointestinal pathologists. Data evaluating interobserver agreement in Barrett's mucosal biopsies with changes at the upper end of the dysplasia spectrum (high-grade dysplasia, intramucosal, and submucosal adenocarcinoma) have not been published. The accurate categorization of pretreatment biopsies drives therapeutic decision making, but if the diagnostic distinction between cancer and high-grade dysplasia in Barrett's biopsies is inconsistent, then the use of these diagnoses to make management decisions is suspect. To this end, our aim was to assess interobserver reproducibility among a group of gastrointestinal pathologists in the interpretation of preresection biopsies. METHODS: All study pathologists agreed upon the histologic criteria distinguishing four diagnostic categories, including high-grade dysplasia; high-grade dysplasia with marked distortion of glandular architecture, cannot exclude intramucosal adenocarcinoma; intramucosal adenocarcinoma; and submucosally invasive adenocarcinoma. The histologic criteria were used to independently review preresection biopsies from 163 consecutive Barrett's esophagus patients with at least high-grade dysplasia who ultimately underwent esophagectomy. Reviewers recorded the specific histologic criteria used to categorize each case and Kappa statistics were calculated to assess interobserver agreement. RESULTS: Using kappa statistics, the overall agreement was only fair (kappa= 0.30). Agreement for high-grade dysplasia was moderate (kappa= 0.47), while agreement for high-grade dysplasia with marked architectural distortion, cannot exclude intramucosal adenocarcinoma and intramucosal adenocarcinoma were only fair (kappa= 0.21 and 0.30, respectively) and agreement for submucosal adenocarcinoma was poor (kappa= 0.14). CONCLUSIONS: The overall poor interobserver reproducibility among gastrointestinal pathologists who see a high volume of Barrett's cases calls into question treatment regimens based on the assumption that high-grade dysplasia, intramucosal adenocarcinoma, and submucosal adenocarcinoma can reliably be distinguished in biopsy specimens.	esophagus
Biweekly fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) for patients with metastatic adenocarcinoma of the stomach or esophagogastric junction: a phase II trial of the Arbeitsgemeinschaft Internistische Onkologie.	BACKGROUND: The combination of docetaxel (Taxotere), cisplatin, and fluorouracil improved efficacy in gastric cancer, but was associated with substantial toxicity. This study was designed to incorporate docetaxel into a tolerable biweekly (once every 2 weeks) oxaliplatin-based chemotherapy regimen. PATIENTS AND METHODS: Patients with measurable, metastatic adenocarcinoma of the stomach or esophagogastric junction and no prior chemotherapy received oxaliplatin 85 mg/m(2), leucovorin 200 mg/m(2), and fluorouracil 2600 mg/m(2) as a 24-h infusion in combination with docetaxel 50 mg/m(2) (FLOT) on day 1 every 2 weeks. Prophylactic growth factors were not administered. RESULTS: Fifty-nine patients were enrolled; 54 received treatment. Patients had a median age of 60 years (range 29-76) and most (93%) of them had metastatic disease. Objective responses were observed in 57.7% of patients with a median time to treatment response of 1.54 months. Median progression-free survival (PFS) and overall survival were 5.2 and 11.1 months, respectively. Twenty-five percent of patients experienced prolonged (>12 months) PFS. Frequent (>10%) grade 3 or 4 toxic effects included neutropenia in 26 (48.1%), leukopenia in 15 (27.8%), diarrhea in 8 (14.8%), and fatigue in 6 (11.1%) patients. Complicated neutropenia was observed in two (3.8%) patients, only. CONCLUSIONS: Biweekly FLOT is active and has a favorable safety profile.	esophagus
