Overall Rectal Cancer RecurrenceAccording to a study published in the British Journal of Surgery, approximately 23% of rectal cancer patients experienced a recurrence within five years. Researchers obtained this data by analyzing the recurrence rates of approximately 680 French cancer patients who had received treatment for rectal cancer between 1976 and 1995. However, other studies have shown that rectal cancer recurrence rates can vary from 4% to 55%.
Impact of Tumor Size on Recurrence StatisticsThe same study mentioned above determined that the chances rectal cancer will return within five years of treatment are 11% for an original tumor smaller than 3 centimeters (cm) and 28% for an original tumor larger than 3 cm.
Impact of Cancer Stage on Recurrence StatisticsWhen the French researchers examined the impact of cancer stage on rectal cancer recurrence, they confirmed that more advanced rectal cancer was more likely to recur. During a five-year period, the rectal cancer recurrence rates for each stage were as follows:
- 10% for stage 1 rectal cancer
- 24% for stage 2 rectal cancer
- 41% for stage 3 rectal cancer
Impact of Hospital Choice on Recurrence StatisticsWhen researchers analyzed data for approximately 3,400 Norwegian rectal cancer patients, they found that which hospital the patients chose significantly impacted their rectal cancer recurrence rates. Specifically, patients who were treated at hospitals that had performed fewer than ten rectal cancer surgeries annually were more likely to have a recurrence in five years than patients who were treated at hospitals that had performed 30 or more rectal cancer surgeries a year.
