This phase II trial studies how well chemotherapy and/or metastasectomy work in treating patients with colorectal adenocarcinoma that has spread to the lungs (metastases). Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Metastasectomy is a surgical procedure that removes tumors formed from cells that have spread from other places in the body. It is not yet known if chemotherapy and metastasectomy together works better in treating patients with metastatic colorectal adenocarcinoma with lung metastases.



I. To compare recurrence-free survival in patients with "low risk" lung-limited metastatic colorectal cancer (mCRC) undergoing pulmonary metastasectomy with or without perioperative chemotherapy.

II. To compare overall survival in patients with "high risk" lung-limited mCRC receiving systemic chemotherapy with or without surgical resection.


I. To compare grade 3 and 4 adverse events in patients receiving surgical resection and/or chemotherapy in the management of lung-limited mCRC.


I. To evaluate for changes in circulating tumor deoxyribonucleic acid (DNA) following surgical resection and/or systemic chemotherapy in patients with lung-limited mCRC.

OUTLINE: Patients are assigned to 1 of 2 risk groups (low or high).

GROUP 1 (LOW RISK): Patients are randomized to 1 of 2 groups.

GROUP 1A: Patients receive standard of care chemotherapy for 3 months prior to and 3 months after undergoing metastasectomy in the absence of disease progression or unacceptable toxicity.

GROUP 1B: Patients undergo metastasectomy.

GROUP 2 (HIGH RISK): All high risk patients receive standard of care chemotherapy for 3 months in the absence of disease progression or unacceptable toxicity. Patients without progressive disease after 3 months are then randomized to 1 of 2 groups.

GROUP 2A: Patients undergo metastasectomy.

GROUP 2B: Patients continue standard of care chemotherapy for 6 months in the absence of disease progression or unacceptable toxicity. Patients with stable disease or radiographic response after 6 months may then cross over to Group 2A.

After completion of study treatment, patients are followed up periodically for up to 5 years.

Inclusion Criteria

Histological confirmation of colorectal adenocarcinoma
Metastatic colorectal cancer involving the lung classified as determined by the treating clinical team
Diagnosis of colorectal metastasis to lung made either histologically with trans-thoracic needle biopsy or clinically based on radiographic imaging
Identification as a medically appropriate candidate for surgical resection of the lung metastasis (metastases) according to the evaluating cardiothoracic surgeon. Standard justification for deeming a patient medically operable based on
Pulmonary reserve adequate to tolerate complete resection of all intrathoracic disease, as deemed by thoracic surgeon, which may be determined by
Baseline forced expiratory volume in one second (FEV1) > 40% predicted
Post-operative predicted FEV1 > 30% predicted
Diffusion capacity of the lung for carbon monoxide (DLCO) > 40% predicted
Absent baseline hypoxemia and/or hypercapnia
Exercise oxygen consumption > 50% predicted
Absent severe pulmonary hypertension
Absent severe cerebral, cardiac, or peripheral vascular disease
Absent severe chronic heart disease
Ability to tolerate surgical resection and acceptable operative risk as deemed by
thoracic surgeon based on performance status and medical comorbidities
Resection/definitive therapy of primary colorectal tumor with no suspicion of recurrence. Prior radiation to a rectal adenocarcinoma is permitted
Identification as a medically appropriate candidate for systemic chemotherapy at the
discretion of the evaluating medical oncologist
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
Ability to provide informed consent for participation
Leukocytes >= 2,000/mcL
Absolute neutrophil count >= 1,000/mcL
Hemoglobin >= 9.0 gm/dL
Platelet count >= 100,000/mcL
Total bilirubin =< 1.5 x institutional upper limit of normal (ULN) (except patients with Gilbert Syndrome, who can have total bilirubin < 3.0 mg/dL)
Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x ULN
Serum creatinine =< 1.5 x ULN OR creatinine clearance (CrCl >= 50 mL/min (if using the Cockcroft-Gault formula)
Patients (men and women) of child bearing potential should use an effective (for them) method of birth control throughout their participation in this study

Exclusion Criteria

Tumor involvement at other metastatic sites (e.g., liver, distant lymph nodes) that has not been definitively treated. Prior surgical resection for metastatic disease at other (non-pulmonary) sites is permitted
Presence of intact primary colorectal adenocarcinoma (or of an anastomotic recurrence)
Previous radiotherapy to a lung metastasis that is still detectable radiographically
Known dihydropyrimidine dehydrogenase (DPD) deficiency that would preclude the patient from tolerating 5- fluorouracil chemotherapy
Prior intolerance of systemic therapies used as standard regimens in the treatment of metastatic CRC that would prohibit further receipt of systemic chemotherapy and/or biologic agents -e.g.,5-fluorouracil, oxaliplatin, irinotecan, anti-VEGF therapies (e.g., bevacizumab, ramucirumab), or anti-EGFR therapies (e.g., cetuximab, panitumumab, for patients with RAS wild-type colorectal tumors)
Prior therapy with regorafenib or trifluridine/tipiracil (TAS-102) for metastatic/unresectable colorectal cancer
Synchronous primary or prior malignancy in the past 5 years other than non-melanomatous skin cancer or in situ cancer
Pregnant or lactating women, as treatment involves unforeseeable risks to the embryo or fetus
