Background: Conventional management of stage IV colorectal carcinoma is pal
liative, The value of resecting both liver and lung colorectal metastases t
hat occur in isolation of other sites of metastasis is undetermined, Object
ives: Our objectives were to (1) assess the efficacy of resecting both hepa
tic and pulmonary metastases, (2) investigate the influence of the sequence
and timing of metastases, and (3) identify the profile of patients likely
to benefit from both hepatic and pulmonary metastasectomy, Patients and met
hods: Of 48 patients identified with resection of colorectal cancer and, at
some point in time, both liver and lung metastases, 25 patients underwent
metastasectomy (resection group). The remaining 23 patients comprised the n
onresection group. Risk factors far death were identified by multivariable
analyses. Results: Median survival was longer after the last metastatic app
earance in the resection group (16 months) than in the nonresection group (
6 months; P <.001). The pattern of risk also differed; it peaked at 2 years
and then declined in the resection group but was constant in the nonresect
ion group. In the resection group, patients with metachronous resections su
rvived longer after colorectal resection (median, 70 months) than patients
with synchronous (median, 22 months) or mixed resections (median, 31 months
; P <.001), Risk factors for death included older age, multiple liver metas
tases, and a short disease-free interval, Conclusions: Younger patients wit
h solitary metachronous metastases to the liver, then the lung, and long di
sease-free intervals are more likely to benefit from resection of both live
r and lung metastases, Patients with risk factors also had better survival
with resection than without resection.
