In addition, in the small subset of patients who did not receive obeslty therapy, the group with a BMI of more than 35 had the most patients with positive lymph nodes. Although a BMI of more than 35 was associated with a high incidence of lymph node metastasis, this could be because of the observed decreased use of preoperative therapy in this group. The increase in tumor size in the group with a BMI of more than 35 may have been attributable to the less frequent use of preoperative therapy in that group and not simply a function of BMI.
