title: [Comparative study of oncologic outcomes after multivisceral resection for stage IIC colorectal cancer between inflammatory and malignant adhesion].
abstract: OBJECTIVE
  To evaluate the differences in oncologic outcomes between inflammatory adhesion and malignant adhesion in patients with stage IIC colorectal cancer after multivisceral resection(MVR).
  
  
  METHODS
  A retrospective review was undertaken of 287 patients who underwent MVR for stage IIC CRC, 120 patients for stage IIB, and 140 patients for IIIA. Patients were divided into two groups: inflammatory adhesion(IA) and malignant invasion(MI).
  
  
  RESULTS
  There were 153 patients with colon cancer and 135 patients with rectal cancer in the stage IIC group. The overall survival was significantly lower in the MI group at 5 years(38.5% vs. 59.4%, P<0.05). Stage IIC patients with IA had similar survival rate to the patients with stage IIB CRC. Compared to the MA group, patients with stage IIIA CRC showed significant differences in 5 years overall survival rate. Univariate analysis showed that differentiation, adhesion pattern, and complication were significant prognostic factors for patients with colon cancer, while pathological characteristics, adhesion pattern, and differentiation were significant for rectal cancer.
  
  
  CONCLUSIONS
  MI is an adverse prognostic factor for patients with stage IIC CRC. T4 should be further classified according to the adhesion pattern.
