SAMPLE SIZE
The study will recruit 1000 participants sequentially at presentation. This will allow the cohort to be representative of the population in terms of cancer stage distribution in the community. We will recruit at least 150 patients from each of the main cancer ‘diagnoses’ or ‘stage’ (e.g. stages 1 to 4) as this will allow for analysis of secondary endpoints and hypothesis-generating follow-up research studies. Although there is no formal statistical sample size calculation, previous studies in colorectal cancer have used populations of similar sample size or less to determine predictors of survival using genetic cluster profile or immune cell profiles. The Cancer Genome Atlas project analysed the genetic profiles 276 colorectal tumours (Stage 1 n=4, Stage 2 n=103, Stage 3 n= 68, Stage 4 n=43) to predict survival without other clinical treatment covariates (Nature 2012, 487, 330–337).

DATA COLLECTION

Health-related quality of life (HRQoL) data

PRIMARY OUTCOME ANALYSIS
The primary endpoint is the establishment of the clinical and patient-reported database and biobank. Thus, no statistical analysis will be conducted for this endpoint.

SECONDARY OUTCOME ANALYSIS
The secondary endpoints are exploratory in nature and aimed to
2a) to define the optimal, individualized, evidence-based treatment recommendations and support pathways for treating CRC in the community.
2b) to better understand the biological processes of colorectal cancer and identify novel predictors of outcomes or new drug targets.

To be able to address aim 2a and 2b, we will need to conduct 4 major exploratory statistical analyses;
a) Clinical patterns of care
b) Longitudinal changes in lifestyle, biological sample and HRQoL data
c) Correlations between covariates
d) Correlations with covariates and clinical outcomes or HRQoL

ANALYSIS PRINCIPLES
1. All analyses will be conducted on an intention-to-treat basis.
2. All tests are two-sided and the nominal level of a will be 5%.
3. All statistical analyses will be unadjusted except where indicated.
4. Subgroup analyses will be carried out irrespective of whether there is a significant
effect of treatment on the primary outcome.
5. We will not impute missing values unless specified otherwise. Where the number of
missing observations is substantial, we will report the number of observations used in the analysis. Last observations will not be carried forward for continuous outcomes.
6. Missing data on questionnaires will be handled as per individual PRO guidelines. Mixed models are valid for data that are missing completely at random and missing at random; patterns of missing data will be assessed to consider potential missing data mechanisms. Sensitivity analysis using multiple imputation will be carried out. Baseline characteristics of participants lost to follow-up will be compared to those who completed follow-up to assess patterns of loss to follow-up, detect any difference in baseline characteristics and thus to provide insights into generalizability of the results.
7. P-values will not be adjusted for multiplicity.
