  • Risk factors associated with the delay reversal ileostomy following sphincter-preserving surgery for rectal cancer

    ObjectiveThis study aimed to discuss the risk factors associated with the delay reversal ileostomy following sphincter-preserving surgery for rectal cancer.MethodsClinical data were collected retrospectively on 130 consecutive patients undergoing defunctioning ileostomy following sphincter-preserving surgery for rectal cancer, between January 2014 and December 2014 in the Sixth Affiliated Hospital of Sun Yat-sen University. According to the reversal time of ileostomy, the patients were divided into two groups, including the delay reversal ileostomy group (≥120 d, n=72) and the normal ileostomy group (<120 d, n=58).ResultsOne hundred and thirty patients were studied (median time to reversal 132 d, range 39–692 d). Logistic regression model showed that adjuvant chemotherapy (OR=14.106, P=0.002), distance of tumor from the anal verge (OR=0.019, P=0.002), and anastomotic leakage (OR=32.440, P=0.001) were significant independent risk factors for delayed reversal. Time to reversal was significantly longer in those patients who had adjuvant chemotherapy, anastomotic leakage, and short distance of tumor from the anal verge.ConclusionAdjuvant chemotherapy, short distance of tumor from the anal verge, and anastomotic leakage are the independent risk factors for delay reversal ileostomy following sphincter-preserving surgery for rectal cancer.

  • Pathogenesis and comprehensive treatment of primary retroperitoneal liposarcoma

    ObjectiveTo understand the pathogenesis and the research progress of comprehensive treatment of primary retroperitoneal liposarcoma (PRLPS) and to provide evidence for clinical diagnosis and treatment.MethodThe recent literatures on the pathological classification, pathogenesis of PRLPS, and comprehensive treatment including the surgery, radiotherapy, chemotherapy, and molecular targeted therapy were reviewed.ResultsThe pathological types of PRLPS were highly differentiated, dedifferentiated, mucoid/round cell, polymorphic, and mixed. The main molecular pathogenesis was the synergistic effect of MDM2 with related genes, abnormal expressions of c-myc gene and microRNAs, Prune-nm23-H1 mechanism, and abnormal protein products of FUS-CHOP fusion gene which regulated the growth of tumor. The treatment of PRLRS included the radical resection, extended resection, and palliative resection combined with radiotherapy, chemotherapy, and molecular targeted therapy.ConclusionsPRLPS is a rare malignant tumor with high recurrence rate, but early diagnosis and treatment are difficult. With the further study of the molecular mechanism of PRLPS, the treatment of PRLPS has been transformed into a comprehensive treatment based on surgery, adjuvant radiotherapy and chemotherapy, and molecular targeted therapy.
