What the trial is, and whether it could suit you
BACKGROUND:
In patients with high risk stage II and stage III colon cancer (CC), curative surgery followed by adjuvant chemotherapy with FOLFOX or CAPOX regimens has become a standard treatment. However, 20 to 30 % of these patients will develop distant metastasis, which ultimately result in death. Perioperative chemotherapy is a promising strategy with potential benefits that could be more effective at eradicating micrometastases. Moreover, shrinking tumor before surgery not only facilitate removal of all the tumor by the surgeon but also reduce tumor cell spreading during the procedure. With recent advances in radiology, preoperative computed tomography allows a good prediction of tumor stage (wall penetration and nodal involvement) prior to surgery. The investigators conducted the present randomized study to explore whether perioperative chemotherapy with FOLFOXIRI regimen compared w

📋 Eligibility rules (as published)
Inclusion Criteria:
* Histologically proven adenocarcinoma or high grade dysplasia on histology plus unequivocal radiological evidence of invasive cancer of the colon(≥ 12 cm from the anal verge).
* pMMR in immunohistochemical detection or MSI-H in MSI test.
* Determined preoperatively by either spiral or multidetector CT: high risk T3 (tumor disruption of muscle wall and extension into pericolic fat with more than 5 mm protrusion into adjacent mesenteric fat) or T4 (tumor penetrates to the surface of the visceral peritoneum or directly invades or is adherent to adjacent organs or structures).
* Patients presenting with acute colonic obstruction may enter the trial only after obstruction is relieved by a successful defunctioning stoma, and when recovered to a fitness level consistent with the other eligibility criteria
* Adequate full blood count: WBC \>3.0 x109/l; Plts \>100 x109/l. Anaemia (Hb \< 10.0 g/dl) is not an exclusion, but should be corrected by transfusion prior to surgery and chemotherapy. If Hb remains low despite transfusions, surgery and chemotherapy can be given at the decision of the surgical and oncology teams.
* Adequate renal biochemistry: serum creatinine was less than 1.5 times the normal value.
* Adequate hepatobiliary function: serum total bilirubin and ALT were less than 1.5 times the normal value.
* Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
Exclusion Criteria:
* Any patient for whom radiotherapy is advised by the MDT
* Strong evidence of distant metastases or peritoneal nodules (M1)
* dMMR in immunohistochemical detection or MSI-L/MS-S in MSI test.
* Peritonitis (secondary to perforated tumour)
* Colonic obstruction that has not been defunctioned
* Serious medical comorbidity, eg uncontrolled inflammatory bowel disease, uncontrolled angina or recent (\<6 months) MI
* Another serious medical condition judged to compromise ability to tolerate neoadjuvant therapy and/or surgery
* Any other malignant disease within the preceding 5 years with the exception of non-melanomatous skin cancer, carcinoma in situ and early stage disease with a recurrence risk \<5%
