The value of CT in the preoperative management of tumors of the sacrum is demonstrated. Essential informations for treatment planning are: involved sacral segment, infiltration of sacral foramina and nerve roots, involvement of the sacroiliac joints, ingression of the lumbar spine, infiltration of the pelvic organs and vessels, sciatic nerve and the dorsal soft tissues. In order to prove the competence of the CT in answering these questions we evaluated the CT-examinations of 30 pat. with 14 primary tumors, 9 metastatic tumors and 7 tumors involving secondary the sacrum. The CT findings were correlated with clinical symptoms and surgical reports in 11 pat., with clinical symptoms alone in 19 pat. There was good correlation in the criterias: location and number of involved segments (8/11, 17/19), infiltr. of SI-joints (11/11), infiltr. of lumbar spine (9/11, 18/19), and infiltr. of pelvic organs (10/11), worse correlation in the criterias: nerve root-involvement (2/11, 3/19), and sciatic nerve-infiltr. (7/11, 15/19). Our conclusions are that CT gives helpful preoperative informations deciding about extent of surgical procedure, and surgical approach. The major problem, however, consist in diagnosis of nerve root and sciatic nerve involvement, therefore in poor prediction of postoperative conservation of neural functions. The knowledge of CT-anatomy of sacrum- and important condition for correct segment-location of the tumor is refreshed by outlines of characteristic segmental CT-sections of the sacrum.

[Determination of intramedullary extension of osteosarcomas using CT with special reference to the epiphyseal groove].

In a study of 21 patients with osteogenic sarcoma of the apendicular skeleton proven by biopsy, the diagnostic value of computed tomography (CT) for the assessment of intramedullary tumor growth, epiphyseal and joint involvement was determined. CT findings were correlated with histopathologic findings. 10 of the 21 tumors were located far from the epiphysis, in 11 cases the epiphysis was infiltrated. Tumorous involvement of the articular cartilage occurred in 3 patients, in one case the tumor extended beyond the joint. In 85% of the cases the CT report concerning tumor location in regard to the epiphysis was verified histologically. In 3 cases CT overestimated tumor extension.

[The incidence of recurrence of intra- and extra-lesional operated metastases of long tubular bones].

Using a collective of 54 patients with 76 operated metastases of long bones in carcinoma of the breast and kidney the frequency of local recurrence after intralesional and extralesional (marginal, wide, radical) resection was investigated. 57 operations were done intralesional, 19 extralesional. Local recurrence was seen in 50.8% in the intralesional group on the other hand in only 15% in the extralesional group (p 0.007). Relief of pain was similar in both groups. The postoperative range of motion had worse results after extralesional resection and endoprosthetic replacement. There was no difference between both groups in the manifestation of further metastases.

[Experiences with ventral stabilization in vertebral metastases in the area of the thoracic and lumbar spine].

43 cases of tumor resection followed by ventral stabilisation are reported in 42 patients with metastases in the spine. Indications for surgery were beginning or incomplete transversal lesion of the spinal cord, bedrest for at least 3 weeks, unsusceible pain caused by instability, or unsuccessful conservative and radiotherapeutic treatment. 46.5% of the cases can be rated as good considering the time of survival and life quality, 18.5% can be judged as a partial success. 7 patients hat to be reoperated in the same level, most of them because of local recurrence. Complications occurred in 40% of the cases. These operations should be performed by a "term of specialists". Postoperative treatment with isotope-, hormone- or radiotherapy is decisive to obtain good results.

[Questionable indication for radical neck dissection in carcinomas of the tongue and floor of the mouth. Results after 4 years].

Based on a 4-year-study the use of ultrasound and preoperative treatment of the neck area is evaluated. The results suggest that there is no indication for radical neck dissection. The therapeutic approach described resulted in a considerable increase in the survival rate during the first 4 years as against the figures published by the DOSAK in 1988.
