Values are presented as number (%), median (range), or median [interquartile range]. Bold styled P-values indicate statistically significant.

LN = lymph node.

^*Includes one patient with well-differentiated pathologic grade.

^†One patient in each group (diffuse and intestinal) missing pathologic grade data.

^‡One patient in the intestinal group is missing tumor regression score data.
