Background: Following surgery for rectal cancer, two unfortunate outcomes for patients are permanent colostomy and local recurrence of cancer. We tested whether a quality-improvement strategy to change surgical practice would improve these outcomes.

Methods: Sixteen hospitals were cluster-randomized to the intervention (Quality Initiative in Rectal Cancer strategy) or control (normal practice) arm.

Background And Objectives: This study assessed lymph node counts, lymph node status (positive or negative), and survival among patients undergoing colon cancer surgery in Ontario, Canada.

Methods: We obtained data from the Ontario Cancer Registry on 960 patients who underwent a major colon cancer resection in years 1991-1993. Patients and hospitals were ranked by lymph node count to correlate lymph node counts and lymph node status.

CBA mice rendered immunodeficient by thymectomy, potentially lethal gamma-irradiation and reconstitution with bone marrow cells were used to grow a wide variety of human tumours as subcutaneous implants. Samples of human melanoma obtained at surgery were successfully passaged by transplantation and produced rapidly growing tumours, some of which metastasized to lung, lymph nodes and the para-aortic node; this system was used as a model for the study of immunotherapy of melanoma. Preliminary results show that intratumour injections of C.

Immunosuppressed mice have been used to support the growth of xenogeneic human and animal malignant cell populations. The optimal conditions for tumor growth are neonatal thymectomy coupled with antithymocyte serum or thymectomy, followed by whole-body irradiation and bone marrow reconstitution. When mice are inoculated with a mixture of normal and malignant cells, the malignant cells have a selective advantage.
