Chemotherapy and/or Metastasectomy in Treating Patients With Metastatic Colorectal Adenocarcinoma With Lung Metastases

This is an interventional treatment trial for Colorectal Adenocarcinoma Read More

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
• Identification as a medically appropriate candidate for systemic chemotherapy at the discretion of the evaluating medical oncologist
• Resection/definitive therapy of primary colorectal tumor with no suspicion of recurrence. Prior radiation to a rectal adenocarcinoma is permitted
• 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
