Conditional survival after neoadjuvant chemoradiotherapy and surgery for oesophageal cancer.

ABSTRACT:

Background

Conditional survival accounts for the time already survived after surgery and may be of additional informative value. The aim was to assess conditional survival in patients with oesophageal cancer and to create a nomogram predicting the conditional probability of survival after oesophagectomy.

Methods

This retrospective study included consecutive patients with oesophageal cancer who received neoadjuvant chemoradiation followed by oesophagectomy between January 2004 and 2019. Conditional survival was defined as the probability of surviving y years after already surviving for x years. The formula used for conditional survival (CS) was: CS_(x|y)  = S_(x + y) /S_(x) , where S_(x) represents overall survival at x years. Cox propo
