The results of treatment in 118 patients with ovarian cancer are presented. The sessional doses were as follows: thioTEPA--200--300 mg or cyclophosphamide--3200--4000 mg+5-fluorouracil--2000--3000 mg. Despite the fact that 116 patients had III--IV stages of the disease, the objective effect of the treatment was observed in 95 of them. Thus, the complete disappearance of tumor was gained in 3 cases, reduction of the tumor size more than by 50%--in 68 patients, more than by 25%--in 18, an insignificant diminishing of tumor, the appearance of its mobility--in 13. Surgical intervention has been performed in 96 patients, that makes 82% of the operability. Supravaginal amputation of the uterus with adnexa and extirpation of the greater omentum have been performed in 76 cases, that yields 67% of resectability. Sole tumors have been removed in 11 patients, the intervention being confined to laparotomy in 6 (5.1%). Pronounced degenerative and necrobiotic alterations in the tumor were revealed by its histochemical assay in 22 patients 40, 50 and 60 days after endolymphatic infusion of chemotherapeutic drugs.

At the Rostov Research Oncological Institute 49 patients with uterine cancer were tested by endolymphatic infusion with the preliminary estimation of the tumor sensitivity to chemical drugs. To test the efficacy of the treatment applied was cytological control of the uterine aspirate every 5 days after the infusion prior to surgery, and also morphological changes in the removed tumors at different terms after endolymphatic polychemotherapy. After administration of the drugs at 2--5 day a cessation of the uterine bleeding, lessening or disappearance of pains were noted usually. Among 14 patients with an enlarged uterus as if in the 8--10 week pregnancy, its size was normalized in 11 patients following the treatment. In 5 of 8 patients with parametrial infiltrates the latter completely disappeared while in 3-separated from pelvic walls. Of 3 patients with vaginal metastases the latter disappeared in one case, in 2 cases these were 2/3--1/2 diminished. Total extirpation of the uterus with adnexa was performed in 41 patients, in three of them a histological assay showed no tumor in the removed specimens.

The complex investigation (histological, histochemical, morphological, electrone microscopy) of lung cancerous tumors from 20 patients, subjected preoperatively to the action of magnetic fields enhancing the antitumor resistance by developing general nonspecific adaptation reactions: activation and training, has revealed a number of morphological changes which indicate a marked antitumor effect of magnetic fields. These changes were maximum manifest after 20-30 sessions. High-differentiated adenocarcinoma proved to be mostly sensitive to the magnetic field action.

[Benign non-epithelial tumors of the stomach]. / O dobrokachestvennykh neepitelial'nykh opukholiakh zheludka.

Six cases of mature non-epithelial tumours of the stomach are described; epithelioid leiomyoma, leiomyoma, lipoma, two fibromata and angiofibrolipoma. Noteworthy is the extremely rarely occurring epithelioid leiomyoma. In one case, lipoma and chronic peptic ulcer coexisted. All the stomach tumours under study were mature benign ones, but some of them presented a clinical course with signs of malignancy probably due to the endogastric growth of the tumour, its dimensions, and its localization near the stomach outlet, as well as to the breach of integrity of the mucous membrane above the tumour.

Ninety eight patients with cervical cancer were subjected to endolymphatic chemotherapy with multiple cytostatic drugs to affect metastatic lymph nodes. A comcentrated mixture of chemotherapeutic drugs (total amount about 20 ml) was injected into plantar lymph vessels, an interval being 10-14 days. The combinations and dosage of the drugs were as follows: thio-TEPA (100-150 mg) or cyclophosphamid (1000-2000 mg)+methotrexate (100 mg)+5-fluorouracil (1000-1500 mg). Subsequently, 76 patients underwent an extended extirpation of the uterus with adnexa, and their lymph-nodes were studied morphologically. It was found that the number of metastases into the lymphnodes was considerably less than it had been expected. Of 45 patients with the disease stage II metastases have been found only in 3 cases (7%). Of 24 patients with cancer stage III the lymphnodes were involved in 4 cases (16.6%). According to the literature data metastatic involvement of the lymphnodes is on an average encountered in 36% for stage II and in 51% - for stage III.
