Esophageal Cancer in Israel has Unique Clinico-Pathological Features: A Retrospective Study

Introduction: Data regarding esophageal cancer (EC) in Israel are limited. The aim of this study was hence to characterize this entity in the Israeli population and to compare it to the literature.

Patients/Methods: This is a retrospective study of all consecutive EC patients treated at our institution between 1997-2013. Data were retrieved from patients' medical files.

Results: Two hundred patients were included. The median age at diagnosis was 70.5 years; 63.5% were males; 63% were Ashkenazi Jews, 29% were Sephardic Jews, and 0.5% were Arabs. Squamous cell carcinoma (SCC) was predominant: 52% versus 45.5% with adenocarcinoma (ADC). SCC was common even in the distal esophagus (45%). The overall 5-year survival rate was 25.5%. A temporal trend (2006-2013 vs 1997-2005) shows a decline in the proportion of SCC (47% vs 63%, p=0.061) and a rise in ADC (50% vs 33%, p=0.041), with a parallel decrease in patients' age (median: 68.5 vs 73 years, p=0.014). In the later period, patients received more treatment for localized and metastatic disease, with a trend for improved median survival (20.1 vs 14.9 months, p=0.658). Ashkenazi Jews were diagnosed at an older age than Sephardic Jews (median: 73 vs. 65 years, p=0.001), had a higher rate of family history of GI cancer (34% vs. 17%, p=0.026) and a higher rate of cardiovascular co-morbidity (41% vs. 24%, p=0.041).

Conclusion: EC in Israel represents an intermediate entity between the Western and the endemic subtypes, showing some unique features. These included delayed reversal of the SCC/ADC ratio, commonness of SCC in the distal esophagus, prevalence of other malignancies and predominance of Ashkenazi ethnicity. The reason for these findings is unclear and its further evaluation is warranted.

The changing epidemiology of esophageal cancer in sub-Saharan Africa - the case of Ghana

INTRODUCTION

Esophageal cancer portends a grim prognosis. Most patients present with incurable disease. Scanty epidemiologic data on the disease has contributed to its low priority on the national. We sought to evaluate the current national trend in the presentation and outcome of esophageal cancer using our institutional experience from 1992 - 2010.

METHODS

This is a retrospective study based on 152 patients who were seen in our institution during the study period. The perioperative data of these patients were retrieved and the relevant details recorded. Histopathological reports were available for 75 patients managed over the period. The study setting was The National Cardiothoracic Centre, which serves as the only tertiary referral centre in the country for cardiothoracic problems.

RESULTS

There were 122 males and 30 females with a mean age of 57.8 ± 11.7 years. The yearly trend from 1992 to 2010 showed a steady increase in the incidence of esophageal cancer. High alcohol consumption and smoking dominated the history of 82.2% of the patients. Squamous cell carcinoma accounted for 78.7% and adenocarcinoma 21.3%. Distribution of esophageal carcinoma by anatomical location was 84.9% for distal third, 11.8% for middle third and 3.3% for upper third. All patients presented with incurable disease.

CONCLUSION

The study shows an increasing incidence of esophageal carcinoma in this country. Alcohol abuse and smoking are major risk factors; squamous cell carcinoma is the dominant histological type in this study.

Avaliação da reconstrução do trato alimentar com tubo gástrico ou colônico na esofagectomia por câncer de esôfago

OBJETIVO: Relatar a experiência com as principais técnicas de reconstrução do trato alimentar após esofagectomia por câncer de esôfago. METODOS: Foram analisados retrospectivamente 68 pacientes submetidos à esofagectomia entre fevereiro de 1997 e novembro de 2005. Todos os pacientes incluídos no estudo foram submetidos à esofagectomia com reconstrução com tubo gástrico ou colônico e anastomose cervical. RESULTADOS: A idade média foi de 55,4 anos (25-74 anos), 50 pacientes eram do sexo masculino e 18 pacientes do sexo feminino, 27 pacientes apresentavam o tumor localizado no esôfago médio e 41 pacientes no esôfago distal, sendo carcinoma epidermóide em 35 pacientes e adenocarcinoma em 33 pacientes. A ressecção foi por via transtorácica em 35 indivíduos e por via transhiatal em 33. A reconstrução com tubo gástrico se deu em 58 pacientes e com tubo colônico em 10 pacientes. A morbidade total da série foi de 52,9%. A mortalidade operatória foi de 5,8%. A sobrevida média foi de 35 meses. CONCLUSÃO: A esofagectomia com reconstrução com tubo gástrico e anastomose cervical é factível tecnicamente, sendo um procedimento realizado de rotina nos pacientes portadores de câncer de esôfago com indicação cirúrgica. Utilizamos, e recomendamos, a reconstrução com tubo colônico principalmente nos pacientes com cirurgia prévia no estômago ou quando da necessidade de ressecção ampliada deste, impossibilitando a confecção da reconstrução do trânsito alimentar com a gastroplastia.
