## Function to compute the St Gallen consensus criterion for prognostication

### Description

This function computes the updated St Gallen consensus criterions as published by Goldhirsh et al 2003.

### Usage

    st.gallen(size, grade, node, her2.neu, age, vascular.inv, na.rm = FALSE)

### Arguments

`size` | tumor size in cm.
`grade` | Histological grade, i.e. low (1), intermediate (2) and high (3) grade.
`node` | Nodal status (0 or 1 for no lymph node invasion a,d at least 1 invaded lymph ode respectively).
`her2.neu` | Her2/neu status (0 or 1).
`age` | Age at diagnosis (in years).
`vascular.inv` | Peritumoral vascular invasion (0 or 1).
`na.rm` | TRUE if missing values should be removed, FALSE otherwise.

### Value

Vector of risk predictions: "Good", "Intermediate", and "Poor".
