In order to evaluate the usefulness of pre-operative intra-arterial selective polychemotherapy (PIASP), we carried out a retrospective study of 107 patients (65 males, 42 females) with locally advanced rectal cancer (LARC) (pT3-4 N0-1 M0), who were treated between 1988 and 1991. Fifty-two patients (MG) underwent PIASP (Adriablastin 60-90 mg, fluorouracil 3-4 g) with subsequent radical surgery. Fifty-five patients (R0) received surgery alone. Angiographic findings after PIASP showed approximately 50-70% reduction in the vascular network in the tumour and surrounding tissues. A post-operative morphological study confirmed the considerable tumour dystrophy, necrobiosis and necrosis. Comparative statistical analysis in two patient groups showed that overall 5-year survival was significantly better in MG (64.76 +/- 1.85%) than in R0 (38.23 +/- 1.74%; chi 2 = 9.1; P < 0.05). A similar situation was observed in all research subgroups: T3 N0 M0 (MG, 85.71 +/- 3.29% and R0, 65.63 +/- 2.85%; chi 2 = 2.61; P < 0.05); T3 N1 M0 (MG, 47.06 +/- 4.68% and R0, 0.0, chi 2 = 14.37; P < 0.05); T4 N0-1 M0 (MG, 8.57 +/- 4.29% and R0, 0.0, chi 2 = 2.09; P < 0.05). Significantly better 5-year survival rates were seen in MG than in R0 with the medial cellular differentiation in carcinoma (77.42 +/- 2.98% and 36.23 +/- 2.41%, chi 2 = 9.81; P < 0.05, respectively), the most frequent histological tumour structures. There is a trend for improved 5-year survival in low differentiation carcinoma (MG, 47.62 + 5.29% and R0, 35.29 +/- 4.37%, chi 2 = 0.28, P > 0.05). The MG group showed eight local relapses of disease (15.38%), while the R0 group showed 21 (38.1%), the MG group demonstrated 12 distant metastasis (23.07%) while R0 demonstrated 19 (34.54%), the median relapse-free survival was 101.6 weeks in MG and 74.45 weeks in R0. The use of the combined PIASP with subsequent surgery treatment of patients with LARC allows a better prognosis than does surgery alone.

The treatment experience of 127 patients with the locally spread rectal cancer was summarized. The combined with preoperative intraarterial chemotherapy course application causes significant injurious effect on the tumor (more than 3 times decrease of the viable tumor tissue part by volume in rectal adenocarcinoma, the appearance of subcapsular necrosis regions in metastatically injured regional lymphatic nodes in 32.2% of observations) and is characterized by low common toxicity.

Combined operative interventions were performed in 375 (14.6%) out of the 2564 patients operated on radically. In 10 patients, evisceration of the pelvic organs was performed. At the preoperative period, 60% of the patients received the intensive irradiation. Among the postoperative complications, the purulent-inflammatory, urologic and cardiovascular ones were the most frequent. The five-year survival after the combined operations was 45.4%, and with preoperative irradiation--60.4%. The recurrences were noted in 23.9 and 5.6% of the patients, respectively.

Results of investigations on the efficacy of splenin as an immunomodulator in the complex treatment of 70 patients with cancer of the rectum revealed its favourable effect on the T- and B-systems of immunity. It was found that immunotherapy effected favourably the immunological properties of the body and this was also supported by clinical data. This makes it possible to recommend splenin as in immunomodulator in the complex treatment of patients with cancer of the rectum.

The analysis of the results of surgical and combined treatment of 2785 patients with rectal cancer was carried out. Radical operative interventions were performed in 2226 (80%) patients. The postoperative lethality was 8%. Before the operation, the intensive irradiation was performed in 959 patients. The five-year survival of patients in stage I cancer was 97.6%, in stage IV--22.7%, the duration of life--117.8 and 37.1 mos., respectively. The use of preoperative irradiation reduces the incidence of cancer recurrences 1.5-2 fold.

In 1174 patients, the pathomorphosis of rectal cancer conditioned by the combined treatment with preoperative irradiation was studied. Preoperative radiotherapy caused considerable disorders in the morphologic structure of a tumour. The survival of patients and incidence of tumour recurrences, depending on the pronouncement of morphologic changes after radiotherapy, were studied. The use of radiation modifiers in combination with radiotherapy facilitated more pronounced damage to the tumour.

The paper discusses the results of treatment of 10 male patients who underwent pelvic evisceration for advanced rectal cancer. Surgical technique is described. In 9 cases, an isolated ileocecal "urinary bladder" was formed; in 1 patient urine was passed into a small intestine segment. The involvement of the urinary bladder and/or the prostate were observed in 6 patients. One patient died shortly after surgery, three--within the first 12 months and another 2--during the second year. Four cases have survived over 5 years, 3 of them surviving over 10 years.
