The retrospective data of this project showed that the following factors were associated with a lower risk of lymph node metastasis: upper oesophageal cancer, high degree of differentiation, squamous-cell carcinoma, shorter tumour length, superficial invasion and some other factors. Given the patients history of cancer, recurrence was high on the differential and needed to be thoroughly evaluated. Their use or mentioning on this website is only for informational purposes.
