Reoperations after Cancer Surgery
Following cancer surgery, a small proportion of patients may develop a complication that requires an unplanned reoperation within 30 days of their original cancer resection. Approximately 2% of lung cancer patients, 5% of colorectal cancer patients, 7% of bladder cancer and 1% of breast, prostate and thyroid cancer patients had an unplanned reoperation within 30 days after cancer surgery.
Measure: Percentage of reoperations after cancer surgery for patients diagnosed with lung cancer
As of this Report:
Reoperation after cancer surgery
- Cancer surgery is commonly used to help treat many types of cancer, including bladder, breast, colorectal, lung, prostate and thyroid cancers.
- Unplanned reoperations after surgery may be due to a number of factors, such as post-operative complications .
- Measuring the rate of unplanned reoperations within 30 days of original cancer resection monitors the quality of cancer surgeries.
What do the results show?
Measure: Percentage of reoperations after cancer surgery for patients diagnosed with bladder, breast, colorectal, prostate and thyroid cancer
As of this Report:
Among patients who underwent lung surgery for a lobectomy or bilobectomy, 2% had an unplanned reoperation after cancer surgery (Figures 1 and 2).
- Patients described in these figures include those who had lobectomies or bilobectomies.
- Among the patients who underwent lobectomies or bilobectomies from fiscal year 2015/2016 to fiscal year 2016/17, 2% had a reoperation after cancer surgery.
- Reoperation rates for lobectomy or bilobectomy patients varied between designated thoracic surgery centres, ranging from 0% to 5%. This indicates low reoperation rates for this patient population.
About 2% of patients who had bladder, breast, colorectal, prostate or thyroid cancer surgery underwent an unplanned reoperation (Figures 3 and 4).
- Among the patients who underwent breast, prostate or thyroid cancer surgery from fiscal year 2015/2016 to fiscal year 2016/2017, 1% had a reoperation within 30 days.
- Among the patients who had bladder cancer surgery during the same period, 7% had an unplanned reoperation after surgery. Among patients who had colorectal cancer surgery, 5% underwent a reoperation during the same period.
- There is some variation in the reoperation rates for all cancer surgery disease sites among regions.
The number of reoperations after cancer surgery can be broken down by the number of cases per disease site (Figure 5).
- From fiscal year 2015/16 to fiscal year 2016/17, the total number of reoperations for prostate cancer within Ontario was the lowest among the disease sites, with 49 reoperations. Colorectal cancer was the highest with 646.
- Additionally, there were a total of 94 reoperations for bladder cancer, 390 for breast cancer and 95 for thyroid cancer.
Why is this important to patient care?
- Reoperation rate is a surrogate measure for assessing complications following cancer surgery. Monitoring reoperation rates is a measure of surgical quality of cancer care.
- Monitoring reoperation rates also highlights the increased cost to the healthcare system from these unplanned procedures.
