Long-term prognosis for colon cancer related to consistent radical surgery: multivariate analysis of clinical, surgical, and pathologic variables.

Despite the improvement in its prognosis in most Western countries, death from colon cancer is still a major problem. In a prospectively planned observation study, a large patient collective from a single institution in Austria was analyzed in terms of the surgical approach and factors influencing survival. A total of 696 patients with colonic carcinomas were admitted to our surgical department between January 1, 1984 and December 31, 1997.

Background: The prognosis for surgically treated gastric cancer patients remains poor in most Western countries compared with reports of Japanese investigators over the last three decades. The aim of the study was to prove whether D2, D3 lymphadenectomy is able to improve long-term survival in a Western gastric cancer patients collective as well.

Methods: A radical surgical procedure using D2, D3 lymphadenectomy on principle as defined by the Japanese Research Society for Gastric Cancer was done prospectively since January 1984.

Long-term results of radical surgery for rectal cancer: multivariate analysis of prognostic factors influencing survival and local recurrence.

Aims: To evaluate consistent radical surgery performed over a 13-year period for rectal cancer in terms of local tumour control and long-term survival.

Methods: Radical surgical procedure principally using total mesorectal excision (TME) for middle and lower rectal tumours, high ligation of the inferior mesenteric artery and sphincter-saving resections (SSR) whenever possible, has been performed prospectively since January 1984.

Results: Tumour resection was possible in 98.

Adjuvant intraperitoneal chemotherapy with carbon-adsorbed mitomycin in patients with gastric cancer: results of a randomized multicenter trial of the Austrian Working Group for Surgical Oncology.

Purpose: Previous studies have demonstrated a beneficial effect of intraperitoneally applied mitomycin bound to activated carbon particles (M-CH) in preventing intraabdominal recurrence following curative surgery for gastric cancer. The Austrian Working Group for Stomach Cancer, a subgroup of the Austrian Working Group for Surgical Oncology, initiated a multicentric phase III trial to evaluate the safety and efficacy of this treatment regimen.

Patients And Methods: A total of 91 patients with a radically resected gastric cancer infiltrating the serosal surface were randomly assigned to receive either 50 mg mitomycin bound to a solution of 375 mg carbo adsorbens intraperitoneally before closure of the abdominal wound (n = 46) or served as a surgical control group (n = 45).
