Objective The aim of this study was to investigate trends in patients' characteristics and comorbidities in esophageal cancer (EC) patients. Background Identifying changing pattern is essential to understand and predict further changes and to plan surgical procedures and resource allocation. Methods Trends in patients' characteristics and comorbidities were evaluated in 4440 EC patients at the Center for Esophageal Diseases in Padova, Italy, during 1980 to 2011. Joinpoint regression analysis was performed to evaluate trends and to estimate annual percentage changes (APCs). Results During the study period, there has been a statistically significant increment of the rate of esophageal adenocarcinoma (APC 3.70). The rates of elderly and of asymptomatic patients increased over time (APCs 0.98 and 6.24), whereas the rates of malnutrition, alcoholic drinking, and gastric ulcer decreased (APCs -1.50, -1.72, and -5.20). Reflux rate increased until 1997 and decreased thereafter (APCs 6.96 and -4.48), whereas the rate of Barrett esophagus increased until 1992 (APC 35.84) and then leveled. The rates of patients with previous neoplasms increased over time (APCs 3.22 and 4.86). There have been significant changes in systemic comorbidities, with an increase of hypertension and cardiac disease (APCs 7.56 and 1.86) and a decrease of advanced liver disease and pulmonary disease (APCs -2.67 and -1.74). Conclusion The current EC patient has more often an esophageal adenocarcinoma and is more frequently elderly, asymptomatic, a survivor of previous neoplasms, and a patient with hypertension and cardiac disease than 30 years ago. On the contrary, malnutrition, alcoholic drinking, gastric ulcer, pulmonary disease, and advanced liver disease decreased.

Laparoscopic myotomy is the currently preferred treatment for achalasia. Our objectives were to assess the long-term outcome of this operation and preoperative factors influencing said outcome.Demographic and clinical characteristics and data on long-term outcome were prospectively collected on patients undergoing laparoscopic myotomy for achalasia at our institution from 1992 to 2007. Treatment failure was defined as a postoperative symptom score higher than the 10th percentile of the preoperative score (9). Logistic regression analysis was used to identify independent preoperative factors associated with successful myotomy.Four hundred seven consecutive patients (220 men, 187 women) underwent the laparoscopic Heller-Dor procedure during the study period; 89 (22%) of them had previously had endoscopic treatment(s). The mortality rate was 0; the conversion and morbidity rates were 1.5% and 1.9%, respectively. The operation failed in 10% of patients (39/407) and the 5-year actuarial probability of being asymptomatic was 87%. Most failures (25/39, 64%) occurred within 12 months of the operation and can be considered as technical failures (incomplete myotomy). Pneumatic dilation overcome the dysphagia in 75% of patients whose surgery was unsuccessful. Considering both the primary surgery and this ancillary treatment, the operation was effective in 97% of achalasia patients. The frequency of sigmoid esophagus, lower esophageal sphincter (LES) resting pressures, and chest pain scores differed statistically between patients with and without recurrences. At multivariate analysis, high preoperative LES pressures (30 mm Hg) was an independent predictor of a good response. The presence of chest pain and of sigmoid esophagus independently predicted the failure of the procedure.Laparoscopic myotomy can durably relieve dysphagia symptoms. High preoperative LES pressures represent the strongest predictor of a positive outcome, probably reflecting a less severely damaged esophageal muscle.

OBJECTIVE:: The aim of this study was to determine whether the risk of systemic disease after esophagectomy can be predicted by the number of involved lymph nodes. SUMMARY BACKGROUND DATA:: Primary esophagectomy is curative in some but not all patients with esophageal cancer. Identification of patients at high risk for systemic disease would allow selective use of additional systemic therapy. This study is a multinational, retrospective review of patients treated with resection alone to assess the impact of the number of involved lymph nodes on the probability of systemic disease. METHODS:: The study population included 1053 patients with esophageal cancer (700 adenocarcinoma, 353 squamous carcinoma) who underwent R0 esophagectomy with >/=15 lymph nodes resected at 9 international centers: Asia (1), Europe (5), and United States (3). To ensure a minimum potential follow-up of 5 years, only patients who had esophagectomy before October 2002 were included. Patients treated with neoadjuvant or adjuvant therapy were excluded. The impact of the number of involved lymph nodes on the risk of systemic disease recurrence was assessed using univariate and multivariate analyses. RESULTS:: Systemic disease occurred in 40%. The number of involved lymph nodes ranged from 0 to 26 with 55% of patients having at least 1 involved lymph node. The frequency of systemic disease after esophagectomy was 16% for those without nodal involvement and progressively increased to 93% in patients with 8 or more involved lymph nodes. CONCLUSIONS:: This study shows that the number of involved lymph nodes can be used to predict the likelihood of systemic disease in patients with esophageal cancer. The probability of systemic disease exceeds 50% when 3 or more nodes are involved and approaches 100% when the number of involved nodes is 8 or more. Additional therapy is warranted in these patients with a high probability of systemic disease

Breast metastases of mucosal/submucosal layers of the esophagus are extremely rare: esophageal involvement is usually part of a mediastinal carcinosis.We report the largest series to date of 25 cases of metastatic esophageal involvement from breast cancer, discussing both diagnostic techniques and treatment options.Twenty-five female patients with a history of breast cancer referred for secondary esophageal involvement (1980-2006) were studied.All patients presented with worsening dysphagia. Twenty-four had undergone surgery for breast cancer a median of 10 years earlier: 1 had received chemoradiotherapy, and 17 had adjuvant radiotherapy/telecobalt therapy following breast surgery. Endoscopic biopsy/cytology were negative for cancer in 17 of 19 patients; in 9 patients, the diagnosis was made with thoracoscopy/laparoscopy. Immunohistochemical staining was done in 10 patients (ER and/or PrR positive). Fifteen patients presented with distant metastatic involvement. Therapy was directed toward dysphagia relief, mostly with endoscopic dilations/prostheses. Complications (4 perforations) occurred only in those 15 patients who had endoscopic dilations/prostheses. Fifteen patients had cytoreductive therapy. Nine of 25 patients are still alive. The median overall survival was 7 months; 1-, 3-, and 5-year survival rates were 44%, 16%, and 8%, respectively.A "breast-esophagus" syndrome can be defined: it is often diagnosed only after excluding other diseases or after relief of dysphagia with adequate therapy. The presence of distant metastases helps the diagnosis of esophageal involvement from mediastinal carcinosis, while diagnosis is a problem in case of mediastinal/pleural disease only: in this case, exploratory thoracoscopy is mandatory for a final diagnosis. Given the high related risk of perforation from endoscopic procedures (dilations/prostheses), the treatments of choice are currently hormone therapy or chemotherapy/radiotherapy.

OBJECTIVE: The objective of this prospective, nonrandomized study was to evaluate the immediate and long-term results of first-line chemotherapy and possible surgery in locally advanced, presumably T4 squamous cell esophageal cancer. SUMMARY BACKGROUND DATA: Locally advanced esophageal cancer is rarely operable and has a dismal prognosis. For this reason, neoadjuvant cytoreductive treatments are more and more frequently used with the aim of downstaging the tumor, increasing the resection rate, and possibly improving survival. Methods: From January 1983 to December 1991, 163 consecutive patients with a presumedly T4 squamous cell carcinoma of the thoracic esophagus (group A) received on average 2.5 cycles (range, 1-6) of first-line chemotherapy with cisplatin (100 mg/m2 on day 1) and 5-fluorouracil (1000 mg/m2 per day, in continuous infusion from day 1 through day 5). Chemotherapy was followed by surgery when adequate downstaging of the tumor was obtained. RESULTS: Chemotherapy toxicity was WHO grade 0 to 2 in 80% of cases, but 3 toxic deaths (1.9%) occurred. Restaging suggested a downstaging of the tumor in 101 of 163 patients (62%), but only 85 patients (52%) underwent resection surgery; it was complete or R0 in 52 (32%) and incomplete or R1-2 in 33. Overall postoperative mortality was 11.7% (10 of 85), morbidity 41% (35 of 85). Complete pathologic response was documented in 6 patients, and significant downstaging to pStage I, IIA, or IIB occurred in 25 more patients. The overall 5-year survival was 11 % (median, 11 months). After resection surgery, the 5-year survival was 20% (median, 16 months); none of the nonresponders survived 4 years after palliative treatments without resection (median survival, 5 months). The 5-year survival rate of the 52 patients undergoing an R0 resection was 29% (median, 23 months). Stratifying patients according to the R, pT, pN, and pStage classifications, the survival curves were comparable to the corresponding data obtained in the 587 group B patients with "potentially resectable" esophageal cancer who underwent surgery alone during the same period. Furthermore, the results were improved in comparison with 136 previous or subsequent patients with a locally advanced tumor who did not undergo neoadjuvant treatments (group C). In these patients, the R0 resection rate was 7%, and the overall 5-year survival was 3% (median, 5 months). CONCLUSION: Although nonrandomized, these results suggest that in locally advanced esophageal carcinoma, first-line chemotherapy increases the resection rate and improves the overall long-term survival. In responding patients who undergo R0 resection surgery, the prognosis depends on the final pathologic stage and not on the initial pretreatment stage.
