Abstract
OBJECTIVE The purpose of our study was to evaluate the sensitivity and accuracy of ferumoxides-enhanced MR imaging in comparison with surgery and intraoperative sonography. SUBJECTS AND METHODS We prospectively evaluated 25 consecutive studies in 24 patients who underwent ferumoxides-enhanced hepatic MR imaging before surgery and intraoperative sonography. Both 1.5-T scanners (13 cases) and 0.2-T scanners (12 cases) were used. Turbo spin-echo T2-weighted sequences were performed before and after the administration of ferumoxides and the images were compared. Lesions were classified as solid or nonsolid and tabulated on standard liver maps. The liver maps from MR imaging were compared with those from surgery and intraoperative sonography. For lesions greater than 1 cm, the regions of interest were measured and contrast-to-noise ratio was calculated. RESULTS Of 93 solid lesions found at surgery, 69 were seen on unenhanced MR imaging (sensitivity, 74.2%) and 87 were seen on ferumoxides-enhanced MR imaging (sensitivity, 93.5%) (p < 0.05). Of the seven benign lesions (five cysts, two hemangiomas) found at surgery, all were correctly identified as benign on MR imaging. Two lesions identified as solid before surgery were not found at surgery. Mean lesion contrast-to-noise ratio for the unenhanced scans was 22.9 and 34.5 (p < 0.001) for the ferumoxides-enhanced scans. Subanalysis of 1.5- and 0.2-T MR imaging revealed similar results with significant (p < 0.05) increases in sensitivity for both. The average size of the lesions missed before surgery was 0.7 cm. CONCLUSION Turbo spin-echo T2-weighted ferumoxides-enhanced MR imaging at either 1.5 or 0.2 T has value in preoperative liver assessment.

Abstract
Solid tumors depend on angiogenesis for growth and metastasis. It has been shown that blood vessel density, as determined by counting the number of capillaries in clustered bursts, is a significant prognostic factor in carcinomas. It is unclear, however, whether vessel density is a prognostic factor in sarcomas. In this study, we examined angiogenesis in sarcomas of various grades and compared their vascular patterns to those of carcinomas. Microvessels were identified by von Willebrand factor staining. The matrix of multiple sarcoma and breast carcinoma specimens were extracted and subjected to Western analysis of various angiogenic factors and inhibitors. Metalloproteinase inhibitor presence was also determined by in situ hybridization. In breast carcinomas, capillaries were clustered in bursts within the stroma of the tumor, whereas the sarcoma capillaries were homogeneously distributed in the tumor stroma. Random blood vessel density per high power field in sarcomas did not correlate with patient prognosis. The matrix of sarcomas and carcinomas contained both angiogenic stimulators and inhibitors. Tissue inhibitor of metalloproteinase-1 was found predominantly in fibroblasts and myofibroblasts in the matrix of carcinoma specimens. The difference in the pattern of angiogenesis in sarcomas and carcinomas may be attributable to the presence of fibroblasts and myofibroblasts in carcinomas, resulting in the compartmentalization of bursts of angiogenic factors. The homogeneous appearance of vessel density in sarcomas observed in the present study would be the consequence of the influence of a single compartment.

Abstract
The authors compare the progression-free survival of patients with unresected or partially resected desmoid tumors treated with radiotherapy with those not given radiotherapy. A retrospective analysis and pathologic review was performed on 14 patients treated at the University of California Los Angeles School of Medicine from 1965 through 1992. Median follow-up was 6 years. The 6-year progression-free survival for irradiated patients was 100%, compared with 50% for those not irradiated (p = 0.04). Of the seven patients irradiated, only two had a complete response and one had a partial response. There was no difference in disease-specific survival between patients irradiated and those not irradiated, because only 1 of 14 patients died of desmoid tumor progression, which caused airway obstruction. This data suggest that radiotherapy may improve the progression-free survival of patients with unresected or partially resected desmoid tumor; however, the number of patients in this series is small. Most patients did not have a complete response to radiotherapy. For patients with tumor adjacent to the airway in the neck or upper thorax, the authors recommend radiotherapy because of the potential for mortality. Otherwise, because tumor progression rarely causes death, one must consider whether the morbidity of treatment would outweigh the morbidity of disease progression.

Abstract
PURPOSE Desmoid tumors have a high propensity for local recurrence with surgical resection. There are many reports describing good responses of desmoid tumors to irradiation, but none have clearly established the indications for adjuvant radiotherapy in treating resectable desmoid tumors. METHODS AND MATERIALS A retrospective analysis was performed on 61 patients with resectable desmoid tumor(s) who were treated at our institution from 1965 to February of 1992. Five patients had multifocal disease and are analyzed separately. Fifty-six patients had unifocal disease, of which 34 had positive surgical margins. Forty-five of the 56 patients with unifocal disease were treated with surgery alone, while 11 were treated with surgery plus adjuvant radiotherapy. Median follow-up was 6 years. Local control was measured from the last day of treatment, and all cases were reviewed by our Department of Pathology. RESULTS Multivariate analysis of the 56 patients with unifocal disease revealed that positive margins independently predicted for local recurrence (p < or = 0.01). Only 3 of 22 patients with clear margins experienced a local recurrence, with a 6-year actuarial local control of 85%. Multivariate analysis of the 34 patients with positive margins revealed that adjuvant radiotherapy independently predicted for improved local control (p = 0.01), and patients with recurrent disease had a slightly higher risk of local recurrence (p = 0.08). The 6-year actuarial local control determined by Kaplan-Meier for patients with unifocal disease and positive margins was 32% (+/-12%) with surgery alone, and 78% (+/-14%) with surgery plus adjuvant radiotherapy (p = 0.02). Subgroup analysis of the patients with positive margins and recurrent disease revealed that those treated with surgery alone had a 6-year actuarial local control of 0% vs. 80% for those treated with surgery plus radiotherapy (p < or = 0.01). Patients with positive margins and primary disease had a trend towards improved local control with adjuvant radiotherapy, but this was not statistically significant. None of the patients treated with radiotherapy developed serious complications or a secondary malignancy. CONCLUSIONS Margin status is the most important predictor of local recurrence for patients with resectable, unifocal desmoid tumor. Adjuvant radiotherapy is indicated in the treatment of patients with positive margins following wide excision of recurrent disease. The role of adjuvant radiotherapy in patients with positive margins following resection of primary disease is controversial, and should be based on a balanced discussion of the potential morbidity from radiotherapy compared to the potential morbidity of another local recurrence. Adjuvant radiotherapy is less likely to benefit those with clear margins due to the excellent results for these patients treated with surgery alone. The local control of desmoid tumor in the adjuvant setting is excellent with total doses ranging from 50-60 Gy, with acceptable morbidity. Field sizes should be generous to prevent marginal recurrences, and large volume MRIs of patients with extremity lesions should be used to identify those patients with multifocal disease.

Abstract
Soft tissue sarcomas appear to be an ideal tumor type for delivering preoperative therapy. The rationale for preoperative therapy is that it is delivered to undisturbed tissue planes with well-oxygenated tissue. This is of great benefit for radiation therapy, because with new computed tomography scan treatment planning it is possible to completely delineate the tumor without surgical clips or postoperative hematoma (or both) obscuring the tumor margin.

Abstract
BACKGROUND This report describes the unusually high response rate of metastatic synovial sarcoma to high dose ifosfamide (14-18 g/m2) when that drug was used to treat 13 consecutive patients with recurrent metastatic synovial sarcoma before surgery (or thoracotomies) to provide optimal salvage therapy for these patients. PATIENTS AND METHODS Thirteen patients with recurrent or pulmonary metastatic synovial sarcoma seen at the Cedars-Sinai Comprehensive Cancer Center (Los Angeles, CA) from April, 1989 through January, 1993 were treated with high dose ifosfamide (14-18 g/m2). Ifosfamide was infused at the dose of 2 g/m2 over a 4-hour bolus infusion, followed by 2-g/m2 24-hour continuous infusions of ifosfamide, for a total of 14 or 18 g/m2 (6-8 days). Mesna (Mesnex, Bristol-Myers Oncology, Princeton, NJ) was infused with the ifosfamide at equimolar doses. Supplemental sodium bicarbonate (180 mEq) was given daily to prevent severe acidosis. Nine of the thirteen patients were treated with prior chemotherapy for their primary tumors. Prior chemotherapy consisted of doxorubicin (Adriamycin, Adria Labs, Dublin, OH) in all patients and doxorubicin combined with cisplatin in eight of them. RESULTS All 13 patients had objective responses to high dose ifosfamide chemotherapy. There were nine partial responses and four complete responses. Five of the patients died of disease at 20-40 months (median, 27 months) from initial therapy. Eight patients have survived from 2 to 43 months (median, 20 months) from initial therapy, and three of these patients are disease free. Those patients surviving disease free had successful surgical removal of their residual metastatic disease after chemotherapy. CONCLUSION Metastatic synovial sarcoma appears to be particularly sensitive to high dose ifosfamide chemotherapy. This experience suggests that there is a role for high dose ifosfamide chemotherapy in preoperative and postoperative adjuvant chemotherapy for primary synovial sarcoma, which is usually always a high grade malignant lesion with a poor prognosis after surgery alone.

Abstract
BACKGROUND The effectiveness of adjuvant chemotherapy in soft tissue sarcomas remains a matter of controversy. The authors reviewed their experience with 14 patients with localized disease treated with intensive doxorubicin-cisplatin-ifosfamide-based chemotherapy. METHODS Fourteen patients with newly diagnosed nonmetastatic synovial sarcoma seen between 1985 and 1992 received intensive chemotherapy and local radiation therapy before surgical resection, followed in most patients by intensive postoperative chemotherapy. Chemotherapy included high-dose cisplatin and doxorubicin or high-dose ifosfamide (14 g/m2) and cisplatin with doxorubicin. RESULTS One (7%) patient had a local recurrence during the study interval and remains free of disease 35 months after re-excision and a second course of intensive chemotherapy. All other 13 (93%) patients remained continuously free of disease after a median follow-up of 37 months (range, 6-85 months). There were no deaths. General toxicity was the reason cited by seven patients who elected not to receive postoperative chemotherapy. For the remaining seven patients who elected to continue treatment, there were only two hospitalization admissions for neutropenia and fever. There was no significant cardiotoxicity, nephrotoxicity, or neurotoxicity. CONCLUSION Additional studies using new intensive systemic adjuvant therapies are needed to determine whether the encouraging results of this experience can be translated into prolonged disease-free and overall survival.

Abstract
In 27 patients with extremity lesions (24 osteosarcoma, three malignant fibrous histiocytoma), a notable decrease in thallium-201 uptake was correlated with a good response to preoperative chemotherapy of the primary tumor. A good response is indicated by a greater than 95% tumor necrosis. Serial quantitative thallium-201 uptake of malignant bone tumors in patients receiving preoperative chemotherapy therefore can accurately predict a good histologic response and prognosis. Serial thallium scintigraphy can furthermore identify poor responses within two weeks after the initiation of treatment, or can prompt an early change in preoperative chemotherapy and facilitate limb salvage surgery.

Abstract
The first three well-documented cases of pure, extraskeletal telangiectatic osteosarcoma of the soft tissues are presented in this article. The distinctive gross features were a predominance of large, blood-filled spaces, which, on histologic examination, were large blood-filled cavities in association with cyst-like walls containing anaplastic spindle cells and definite osteoid production in two of three cases. One of the cases is of additional clinical interest because the teen-aged daughter of the woman patient had died 1 year previously of a high-grade intramedullary osteosarcoma of bone.

Abstract
Lipopolysaccharide (LPS) from the Y4 strain of this bacterium, which is implicated in the pathogenesis of juvenile periodontitis, was incubated with human peripheral blood lymphocytes (PBL) and its action compared to that of LPS from Escherichia coli. Both LPS augmented cytotoxicity measured against natural killer (NK) cell-resistant tumour targets within 24 h of incubation. Cytotoxicity was exclusively found in NK-enriched low-density large granular lymphocyte fractions, as separated by Percoll gradient. LPS activated NK cells without stimulating high levels of proliferation. The minimum concentration of A. actinomycetemcomitans LPS required to activate NK cells was 1 microgram/ml; higher concentrations did not significantly increase this activation. LPS had no synergistic effect on the induction of PBL cytotoxicity by interleukin-2. In contrast, LPS pre-activated monocytes inhibited the induction of lymphocyte cytotoxicity by either interleukin-2 or LPS.

Abstract
To determine the role of chemotherapy in the multidisciplinary treatment of patients with osteosarcoma, a randomized prospective trial of postoperative adjuvant chemotherapy was begun in 1981. Fifty-nine patients with nonmetastatic classic intramedullary osteosarcoma were randomized; 32 received postoperative adjuvant chemotherapy consisting of high-dose methotrexate, Adriamycin (Adria Laboratories, Columbus, OH), and BCD (bleomycin, cytoxan, actinomycin D), and 27 patients received no adjuvant chemotherapy. At a median follow-up of 2 years, there was a statistically significant improvement in both disease-free and overall survival in those who received adjuvant chemotherapy. In addition, there was no difference in the less than 20% disease-free or overall survival of patients treated in the 1970s who did not receive chemotherapy, as compared with the concurrent nontreatment controls. Therefore, with identical staging procedures, uniform surgical management, and standard pathologic evaluation, postoperative adjuvant chemotherapy definitely improves disease-free and overall survival in patients with osteosarcoma.

Abstract
Since 1979, 16 patients with cancer of the rectum and anus have been treated without abdominoperineal resection. All have received radiotherapy. Nine of these had local excision before receiving radiotherapy. There has been no evidence of recurrent cancer in 15 of the 16 patients with a median follow-up period of 24 months (range 14 to 52 months) for a recurrence rate of 6 percent. We conclude that limited excision, radiotherapy, or both are viable alternatives to abdominoperineal resection of small, early cancers of the rectum and anus.

Abstract
A nontender, nonpulsatile large anterior neck mass was found at operation to be an atherosclerotic aneurysm of the vertebral artery, an extremely rare condition. Proximal control and distal control were obtained and the aneurysm was excised. Aneurysms of the vertebral artery are infrequent but well-defined complications in connective tissue disorders such as the Ehlers-Danlos syndrome, and they can develop subsequent to penetrating neck trauma. However, no cases of atherosclertic vertebral artery aneurysms have been reported recently in the English-language literature. The case presented illustrates that this rare condition should be considered in all patients who have neck masses of undetermined etiology.

Abstract
One hundred and thirty-four patients with advanced malignant disease were treated with 496 infusions of high-dose methotrexate (HD-MTX) followed by citrovorum factor rescue. Most patients had failed to respond to previous combination chemotherapy. The overall response rate was 29% with 33 partial responses and six complete responses observed in patients with a variety of tumors. Plasma MTX levels were monitored in all patients during each course of therapy in order to identify those patients with delayed plasma MTX clearance. Patients with abnormally slow rates of plasma MTX decay received escalated doses of citrovorum factor rescue in order to prevent drug-induced toxicity. In general, during this study HD-MTX was well-tolerated. Because serious toxicity was neither frequent, severe, nor unpredictable, its use was not limited. HD-MTX should now be evaluated in well-designed controlled clinical trials to compare its antitumor activity to that of conventional- or standard-dose MTX regimens in diseases where HD therapy appears to have efficacy.
