[Aggressive fibromatosis of the small pelvis].

Experience in the treatment of 25 patients with aggressive fibromatosis of the true pelvis is discussed. To establish a precise diagnosis obligatory and special methods of examination were applied. Secondary changes in the adjacent organs and structures were found in 24 patients. Radical operations were conducted on 19 (76%) patients, in 13 of them the interventions were combined. The mean duration of the operations was 5.3 hours. Complications developed in 17 out of 19 patients. Hemorrhage was the most frequent (in 12 out of 19 patients) and menacing complication. The blood loss was 3036.8 ml on the average. Recurrences were registered in 8 out of 19 (42.1%) patients.

[Current theories on the origin of Reed-Sternberg cells in lymphogranulomatosis].

The literature data and the results of the authors' own investigations on the enzymatocytochemical signs, surface membrane receptors and antigens of Hodgkin's and Reed-Sternberg cells have been presented. Possible genesis of giant multinuclear cells from activated T- or B-lymphocytes, histiocytes,+-macrophages or interdigitirring reticular cells in lymphogranulomatosis have been discussed.

[Conservative surgery in the initial forms of cancer, malignant adenomas and villous tumors of the rectum].

The results of sparing transanal operations performed in 519 patients with the early forms of cancer, malignant adenomas and villous tumors of the rectum are presented. On the basis of studying the five- and ten-year survival, it is shown that local sparing operations provide stable and prolonged cure of the patients. The dependence between recurrence of adenomas, peculiarities of their macro- and microscopic structure has been traced.

[Peculiarities of diagnosis and treatment of initial forms of rectal cancer].

Of 3185 patients, the stage I rectal cancer was diagnosed in 220 (6.9%), stage II--in 156 (4.9%), stage III--in 1948 (61.2%), stage IV--in 861 (27.0%). The causes of late diagnosis were the following: asymptomatic course of the disease (74.2%), delayed taking the medical advice, incomplete (without rectal inspection) examination of the patients. The sphincter-preserving operations were performed in 86.3% of the patients. The 5-year survival of patients in stage I was (97.6 +/- 2.5)%, in stage II--(75.7 +/- 4.1)%.

[Combined surgical interventions in disseminated forms of rectal cancer].

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.

[Clinico-morphologic aspects of the combined treatment of locally disseminated cancer of the rectum].

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.

[Pelvic exenteration as a means of improving the resectability of advanced cancer of the rectum].

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.

[Suppression of the proliferative activity in in vivo tissue culture of esophageal and stomach tumor cells during preoperative irradiation].

Pathomorphological changes and indices of proliferative ability of tumour tissue in the esophagus and in the cardia are studied in 14 patients after and without the preoperative irradiation following its cultivation in diffuse chambers. The tissue was implanted into the abdominal cavity of 84 rats. Inhibition of the mitotic activity and synthesis of DNA in cell nuclei as well as the impairment of the formation processes typical of the unirradiated blastomas of the same histological structure in the tissue culture in vivo evidence for a pronounced effect of irradiation.

[Enhancement of the effect of radiotherapy of Guerin's carcinoma by tinidazole].

Tinidazol, an electron-acceptor compound, was studied for its influence on the effectiveness of radiation treatment of Guerin's carcinoma. It was shown in terms of tumour regression, percentage of inhibition, time of tumour volume doubling, rate of the tumour growth renewal and average survival that in the presence of tinidazol, the antitumour effectiveness of radiation treatment is 1.6-2.0 times as high as radiation alone. Morphologic studies confirm the ability of tinidazol to enhance the radiation damage.

[Accumulation and localization of 67Ga citrate in cancerous lung tissue during diagnostic use of the preparation].

Altogether 89 patients were examined using scintigraphy with 67Ga-citrate. Radiometric, scintigraphic, radioautographic and histological investigation of the operation material of 15 patients was conducted. The diagnostic accuracy was 92.1%, sensitivity 98.6%, specificity 75%. The investigation of the operation material showed that RP accumulation in the peripheral part of tumor was 4-4.5 times higher and in its central part 2-3 times higher than in the unaffected pulmonary tissue. Elevated RP accumulation was found in the capsular wall in inflammatory processes as well as in lymph nodes with anthracosis. Recovered silver grains on histoautoradiograms of tumor tissue zones were mainly localised around isolated cells and their groups in the intercellular space.

[Ultrastructural characteristics of chondroblastomas].

The ultrastructure of chondroblastomas and two new ultrastructural peculiarities typical of the given form of tumours are described. Being typical but not constant these peculiarities may be an additional argument indicating that such cells may be regarded as chondroblastoma cells. The ultrastructure of these cells is similar to that of normal epiphyseal chondrocytes and differs from the ultrastructure of chondrosarcoma cells.
