[Resection of combined or sequential lung and liver metastases of colorectal cancer: indication for everyone?].
Successful sequential resection of isolated hepatic and pulmonary metastases of colorectal cancer (crc) has been reported, however long-term results of large series are lacking. Therefore, we retrospectively analysed data of patients in whom sequential hepatic and pulmonary resection for metastases was performed.


METHODS
From the records of our hospital we identified 25 patients (19.5 % of all patients operated for hepatic or 33 % for lung metastases due to crc) with colorectal cancer who had pulmonary and hepatic resection for metastatic disease between 1991 and 2002. 11 of these had primary colonic cancer and 14 rectal cancer. None of the patients died perioperatively. Long-term results were correlated with the staging of the primary tumour, the number of metastases, disease free interval between primary tumour operation and occurrence of metastatic disease.


RESULTS
Five-year survival rate was 33.5 % following the resection of the first metastasis. Three year survival after resection of the second metastasis was 39 %. The disease free interval was 20 months (mean). Long-term results were clearly influenced by the disease free interval: < 1 year (n = 6) median 50 months after resection of the crc; > 1 year median 90 months (n = 19). Further on R0 resection was important for long-term survival: Median survival was 32.5 (+/- 4.1) months following resection of the second metastasis but only 9.9 months after R > 0 resection.


CONCLUSIONS
These results confirm that sequential resection of hepatic and pulmonary metastases can be performed with curative intention provided a systemic spread of the disease is excluded. The surgeon's opinion of resectability should be obtained in patients with such metastases before the patient is scheduled for palliative conservative treatment.
