Short and long-term advantages of transhiatal and transthoracic oesophageal cancer resection

Two major surgical strategies to improve survival rates after oesophagectomy for oesophageal cancer have emerged during the past decades; (limited) transhiatal oesophagectomy and (extended) transthoracic oesophagectomy with two-field lymphadenectomy. This overview describes short and long-term advantages of these two strategies. In the short term, transhiatal oesophagectomy is accompanied by less morbidity. In the long term, this strategy is only preferable for patients with tumours located at the gastro-oesophageal junction, without involved lymph nodes in the proximal compartment of the chest. For patients with tumours located in the oesophagus, the transthoracic route with extended lymphadenectomy is probably preferred, because of improved long-term survival. © 2008 Elsevier Ltd.

Accuracy and reproducibility of 3D-CT measurements for early response assessment of chemoradiotherapy in patients with oesophageal cancer

AbstractBackgroundChemoradiotherapy is increasingly applied in patients with oesophageal cancer. The aim of the present study was to determine whether 3D-CT volumetry is able to differentiate between responding and non-responding oesophageal tumours early in the course of neoadjuvant chemoradiotherapy.Patients and methodsSerial CT before and after two weeks of neoadjuvant chemoradiotherapy was performed in the multimodality treatment arm of a randomised trial including patients with oesophageal carcinoma. CT response was measured with the change in tumour volume between baseline and after 14 days of neoadjuvant therapy. Receiver Operating Characteristic (ROC) analysis was used to evaluate the ability of 3D-CT as an early imaging marker of response.ResultsCT response analysis was performed in 39 patients, of whom 26 patients were histopathological responders. Median tumour volume increased between baseline and after 14 days of chemoradiotherapy in histopathological responders as well as in non-responders, though changes were not statistically significant. The area under the ROC curve was 0.71.ConclusionTumour volume changes after 14 days of neoadjuvant chemoradiotherapy as measured by 3D-CT were not associated with histopathological tumour response. CT volumetry should not be used for early response assessment in patients with potentially curable oesophageal cancer treated with neoadjuvant chemoradiotherapy
