Patients receive oxaliplatin intravenously (IV) over 2 hours, irinotecan hydrochloride IV over 90 minutes, and leucovorin calcium over 2 hours on day 1, and fluorouracil IV over 46-48 hours on days 1-3. Treatment repeats every 14 days for 8 cycles in the absence of disease progression or unacceptable toxicity. Within 2-8 weeks of completing neoadjuvant chemotherapy, patients undergo surgical resection. Patients then receive oxaliplatin IV over 2 hours, irinotecan hydrochloride IV over 90 minutes, and leucovorin calcium over 2 hours on day 1, and fluorouracil IV over 46-48 hours on days 1-3. Treatment repeats every 14 days for 4 cycles in the absence of disease progression or unacceptable toxicity.

Patients undergo surgical resection. Beginning 3-12 weeks after surgery, patients then receive oxaliplatin IV over 2 hours, irinotecan hydrochloride IV over 90 minutes, and leucovorin calcium over 2 hours on day 1, and fluorouracil IV over 46-48 hours on days 1-3. Treatment repeats every 14 days for 12 cycles in the absence of disease progression or unacceptable toxicity.

Overall survival is defined as the time from randomization to death due to any cause. The median and 95% confidence intervals are estimated using the Kaplan-Meier estimator. The treatment arms will be compared using a stratified Cox regression model, and hazard ratios from each arm will be estimated.

Disease-free survival (DFS) is defined as the time from randomization to the date of progression prior to surgery, metastases detected during surgery, recurrence (locoregional and/or distant) after resection, and death due to all causes, whichever occurs first. The median and 95% confidence intervals are estimated using the Kaplan-Meier estimator.

Time to locoregional recurrence (TLR) is defined as the time from randomization to the date of locoregional recurrence after resection. The median and 95% confidence intervals are estimated using the Kaplan-Meier estimator.

Time to distant metastases (TDM) is defined as the time from randomization to the date of metastases prior to surgery, metastases detected during surgery, or distant recurrence after resection. The median and 95% confidence intervals are estimated using the Kaplan-Meier estimator.

The rate (percentage) of patients with negative resection margins after undergoing surgery.

The rate (percentage) of patients who cannot undergo surgery due to adverse events, progressive disease, death, poor performance, or patient/physician decision, are deemed unresectable before surgery, or resection was not performed during surgery.

The rate (percentage) of patients who achieve a pathologic complete response (pCR) confirmed by histopathologic review of the surgical specimen.

The maximum grade for each type of adverse event will be recorded for each patient, and frequency tables will be reviewed to determine adverse event patterns within treatment arms and during the following three time points: during perioperative chemotherapy, surgical complications during surgery and post-operative period for 30 days, and during adjuvant chemotherapy.

Dose intensity is defined as the percentage of total cumulative dose the patient received divided by the total dose planned per protocol times 100.

The number of cycles received is defined as the total number of cycles that the participant received at least one dose of any agent in mFOLFIRINOX.

Quality of Life Questionnaire-Core 30 (QLQ-C30) is a 30-item questionnaire to assess the overall quality of life in cancer patients. QLQ-C30 includes functional scales (physical, role, cognitive, emotional, and social), global health status, symptom scales (fatigue, pain, nausea/vomiting), and other (dyspnoea, appetite loss, insomnia, constipation/diarrhea, and financial difficulties). Most questions used 4-point scale (1 'Not at All' to 4 'Very Much'); 2 questions used 7-point scale (1 'Very Poor' to 7 'Excellent'). Scores are averaged, and transformed to 0-100 scale; higher score=better level of physical functioning, greater occurrence of nausea/vomiting, and greater occurrence of diarrhea.

Multivariate Cox proportional hazards models will be fit for overall survival (OS) endpoint (defined above) with covariates corresponding to baseline diet and lifestyle questionnaire responses and hazard ratios and 95% confidence intervals will be reported.

Multivariate Cox proportional hazards models will be fit for disease-free survival (DFS) endpoint (defined above) with covariates corresponding to baseline diet and lifestyle questionnaire responses and hazard ratios and 95% confidence intervals will be reported.

Multivariate Logistic models will be fit for the binary endpoint of grade 3+ adverse event (patient experiences at least one grade 3 or higher adverse event during treatment)

Comparison between computed tomography (CT)-based radiomics and histological tumor fibrosis proportions will be measured using Spearman's rank correlation coefficient.

Multivariate Cox proportional hazards model will be fit for overall survival (OS) endpoint (defined above) with covariates chosen from all available radiomics features using the least absolute shrinkage and selection operator (LASSO) method with 10-fold cross-validation (CV) and additionally adjusted for clinically important confounders. After the final model is selected the area under the receiver operating characteristic curve (AUC) will be reported to indicate the prediction performance of the radiomics model.

The Cox proportional hazards model will be used to determine the association between each marker and time to recurrence and survival controlling for other baseline factors such as age, gender, treatment, primary tumor site, degree of differentiation.
