The use of megavoltage therapy has in some investigations been shown to be associated with improvement in the prognosis of gynaecological carcinoma. Our purpose was to clarify whether the character or number of complications has changed with the increased effectiveness of treatment. During the years 1967-1970 a total of 449 cases of gynaecological carcinoma (cervical, endometrial, ovarian) were treated at the Department of Obstetrics and Gynaecology and the Department of Radiation Therapy, Turku University; tele-Cobalt was used for external radiation. The comparison period was the years 1963-1965 when 289 patients were treated, the external radiation then in use being X-ray therapy. Intracavitary radiation was given in both groups using the modified Stockholm method for cervical carcinoma and the Heyman method for endometrial carcinoma. Operative activity was about the same in both periods. Patients with cervical carcinoma treated with tele-Cobalt appeared to have a higher frequency of severe intestinal complications (12.4%) than patients receiving X-ray therapy (6.0%); the difference was not, however, statistically significant. The same is true concerning the treatment groups of ovarian cancer (4.8% and 0% respectively) and those of endometrial carcinoma (5.2% and 1.2%). However, if all the patients as a group are considered and also those with urological complications, the difference was significant (p less than 0.05), the frequency of complications being 7.6% for patients treated with tele-Cobalt and 4.2% for those treated with X-ray therapy. One must take into account that in all cases the most difficult complications were seen in patients treated with tele-Cobalt, where surgical treatment was necessary in 29%.

In a prospective therapeutic study, 571 cases of endometrial cancer in pathological stage I were treated initially with total hysterectomy and received 6 weeks after surgery double high-dose-rate iridium 192 irradiation of the vagina (afterloading technique). The single dose was 700 cGY (at 2 cm distance from the applicator axis). Postoperative treatment planning was based on the prognosticators of depth of myometrial invasion and tumor grading with subtypes. External irradiation was prescribed only for patients with poor prognostic factors (Cobalt-60,5600 cGY on the pelvis wall, 30 fractions). At the time of this report, the patients had been followed up for 6 to 96 months after their original therapy. Survival was calculated by the life table method. 327 cases with slight tumor infiltration, independent of the tumor morphology, received postoperative vaginal irradiation only. Survival rate was 90.6%. 27 cases with tumor infiltration of the middle third of the myometrium and grade 1 tumors, received also only vaginal irradiation. Survival rate was 100%. 101 cases with tumor infiltration of the middle third of the myometrium and grade 2 and 3 tumors, received vaginal irradiation plus external irradiation. Survival rate was 89.9%. 116 cases with tumor infiltration of the external third of the mymetrium and any tumor grade, received vaginal irradiation plus also external irradiation. In these patients with poor prognosis, the survival rate was 85%. Differences between groups are not significant. Considering the treatment group with good prognosis and the group with poorer prognosis and the additional external irradiation, the survival figures were quite similar (90.6% and 87.9% respectively). In spite of the unfavorable situation of patients with poor prognosticators, treatment results after the additional external irradiation were rather similar to those cases with good prognosticators and without external irradiation. The value of external irradiation in cases of endometrial cancer in stage I with unfavorable prognosticators seems to be quite clear. This therapy improvement was all the better, because side effects of external irradiation were low (0.2% rectovaginal fistulas) and in case of irradiation of the vagina only, no severe side effects occurred. Relapse rate for the treatment group with good prognosis and vaginal irradiation only was 0.6% (2 from 354) and for the group with poor prognosis and additional external irradiation 2.8% (6 from 217) respectively.

Surgery should be an integral part of the management of the patient with endometrial cancer. Only patients with severe medical conditions should be treated with radiation therapy alone. Although radiation therapy alone often can cure endometrial cancer, five-year-survival figures are poorer than for operation. At the University of Vienna, I. Department of Gynecology, 198 patients with endometrial cancer were treated by radiation therapy alone. Using the afterloading-iridium-192-technique, the three-year-survival-rate was 76%, five-year-survival 60%. A comparable group of 185 cases treated by intracavitary radium-226 had five-year-survival of only 40% (p less than 0.001). With afterloading high-dose irradiation younger patients had five-year-survival of 75%, older patients (70 years and more) 51%; when tumor grading was one survival figures reached 76%, with tumor grading 2 and 3 only 41%. Severe radiation side effects did not occur with the optimal intrauterine single dose of 850 cGy (four times) and 700 cGy intravaginal (once), nor could any severe complications be observed when the total rectal dose did not exceed 500 cGy. In only 8% of the cases the treatment was combined with external irradiation (Cobalt-60). Intrauterine and intravaginal applications were performed without anaesthesia and the hospitalisation time was very short.
