The poor prognosis for esophageal cancer could be improved if lesions were detected at an early stage. To detect early esophageal cancer, endoscopic screening of the esophagus with the Lugol dye method was performed in patients with head and neck cancers who were asymptomatic but regarded as being at high risk for synchronous or metachronous esophageal cancer. Of 178 patients screened, 9 had esophageal cancer (5.1%). Eight of these patients (89%) were at early stages with no lymph node metastasis. Most of the lesions (9 of 13 lesions) were not detectable by barium studies or ordinary endoscopic study. The epidemiologic statistical analysis of the patients confirmed that they had a significantly high observed and expected number (O/E) ratio (39.7; P less than 0.001). These results demonstrate the value of endoscopic screening of the esophagus with the Lugol dye method in patients with head and neck cancers and imply that endoscopic screening with the Lugol dye method may be useful for detecting early esophageal cancer in individuals at risk for other causes.

Results of this trial suggest that a combination of preoperative full-dose gemcitabine, concurrent 3D-conformal radiation, surgery, and postoperative LPC is feasible for the treatment of T3-pancreatic cancer. Using the method described in this article, we were able to effectively reduce the incidence of both local and liver recurrence. Therefore, this type of combination therapy seems promising for improving long-term outcomes for patients with T3-cancers of the pancreas. This study is registered with University hospital Medical information Network clinical trials Registry number, UMIN000001804.

Salvage surgery is a highly invasive and morbid operation, which is performed on immunocompromised hosts. The indication must be carefully considered, with care taken to avoid non-curative surgery.
