Natural History of Esophageal Squamous Cell Carcinoma, with Special Reference to Evaluation of Clinical Growth Rate by Tumor Volume Doubling Time
Esophageal carcinoma is a common malignancy with a poor prognosis, despite recent advances in treatment. We previously reported ten patients with rapidly growing squamous cell carcinomas of the esophagus, and showed that the rapid growth of this tumor explains both why it is seldom detected at an early stage and why prognosis is poor . However, reports at variance with our findings have been published [2–4]. In particular, the selection of patients in our previous study may have presented a problem, particularly since the number was small. Moreover, to determine if tumor growth is actually rapid, it is necessary to evaluate tumor growth objectively by comparison with malignancies of other organs.
