Abstract
To increase the effect of cisplatin on locoregional osteosarcoma, the short-term effect of hyperthermic isolated regional perfusion (HIRP) with cisplatin (30 mg/L extremity volume) was studied in 28 dogs with spontaneous osteogenic sarcoma, using clinical, radiological, and histological parameters. Thirty days postoperatively, mortality was 14.3%. Total platinum levels at the start of perfusion were 28.2 +/- 14.3 mg/L. A significant improvement (P < 0.001) in clinical score was observed in the overall group at 6 and 12 weeks after perfusion. The radiological parameter showed a stationary X-ray 2 weeks after perfusion and an improved X-ray 6 weeks after perfusion. Overall histological scores showed a moderate effect according to the Huvos classification. No additional therapeutic effect, according to the three parameters, could be demonstrated by increasing the perfusate temperature by 1 degrees C. HIRP with cisplatin is feasible in the local treatment of spontaneous osteosarcoma in dogs with acceptable locoregional toxicity. However, the histological results were modest, with none of the dogs showing a complete response 6 weeks after perfusion. Therefore, the search for the ideal perfusion agent with substantial contribution to the limb-sparing treatment in human osteosarcoma continues.

Abstract
The authors review their experience of 4 years with isolated limb perfusion for the application of high dose TNF-alpha associated to IFN-gamma and melphalan for the treatment of regionally advanced tumours such as malignant melanoma, soft tissue sarcoma and epidermoid carcinoma. In malignant melanoma, the complete remission rate reaches 91%. In irresectable soft tissue sarcoma, this treatment when used as a neoadjuvant treatment saves the limb from amputation in 87.5% of the cases. Similar results are obtained for epidermoid carcinoma. With the regional application of high doses of TNF-alpha associated to chemotherapy and IFN-gamma, it has been possible to validate the concept of a strategy based on a dual targeting, that is the selective impact of the intratumoral vessels by TNF-alpha and of the tumour cells by chemotherapy. This approach appears to be the treatment of choice for locally advanced tumours of the limbs. However, as a single therapy, this procedure should be considered in melanoma as an induction therapy, and in sarcoma, as a preoperative treatment.

Abstract
PURPOSE To develop a statistical model that predicts the histology (necrosis, mature teratoma, or cancer) after chemotherapy for metastatic nonseminomatous germ cell tumor (NSGCT). PATIENTS AND METHODS An international data set was collected comprising individual patient data from six study groups. Logistic regression analysis was used to estimate the probability of necrosis and the ratio of cancer and mature teratoma. RESULTS Of 556 patients, 250 (45%) had necrosis at resection, 236 (42%) had mature teratoma, and 70 (13%) had cancer. Predictors of necrosis were the absence of teratoma elements in the primary tumor, prechemotherapy normal alfa-fetoprotein (AFP), normal human chorionic gonadotropin (HCG), and elevated lactate dehydrogenase (LDH) levels, a small prechemotherapy or postchemotherapy mass, and a large shrinkage of the mass during chemotherapy. Multivariate combination of predictors yielded reliable models (goodness-of-fit tests, P > .20), which discriminated necrosis well from other histologies (area under the receiver operating characteristic (ROC) curve, .84), but which discriminated cancer only reasonably from mature teratoma (area, .66). Internal and external validation confirmed these findings. CONCLUSION The validated models estimate with high accuracy the histology at resection, especially necrosis, based on well-known and readily available predictors. The predicted probabilities may help to choose between immediate resection of a residual mass or follow-up, taking into account the expected benefits and risks of resection, feasibility of frequent follow-up, the financial costs, and the patient's individual preferences.

Abstract
PURPOSE A wait-and-see policy for patients with stage I nonseminomatous testicular germ cell tumors (NSTGCT) was evaluated in a prospective study. The frequency and time of recurrence, detection of recurrence, and presence of unfavorable prognostic factors were investigated. PATIENTS AND METHODS During the period 1982 to 1992, 154 patients with stage I NSTGCT (median age, 29 years) underwent orchidectomy and were monitored at follow-up evaluation with physical examinations, alfafetoprotein (AFP) and beta-human choriogonadotropin (hCG) levels, chest x-rays (CXR), and computed tomographic (CT) scans of the abdomen and chest. Multivariate logistic regression analyses were performed to identify prognostic factors. RESULTS During a median follow-up period of 7 years (range, 2 to 12), recurrence was found in 42 patients (27.3%). All cases of recurrence were detected within 2 years, 90% in the first year after orchidectomy. In 29 patients (69.0%), recurrence was detected in the abdominal lymph nodes. Nine patients (21.4%) had metastases in the retroperitoneum and mediastinum and/or lungs, and four patients (9.6%) had metastases only in the mediastinum or lungs. The majority of recurrences (97.6%) were detected by tumor markers and CT scans. Recurrence was related to the presence of vascular invasion, embryonal carcinoma (E), elevated preoperative hCG level, and absence of mature teratoma (M). Only vascular invasion was an independent risk factor. After polychemotherapy treatment for recurrence, the survival rate for the total group was 98.7%. CONCLUSION The wait-and-see policy is a reliable method for follow-up monitoring of patients with stage I NSTGCT. Even in patients with unfavorable prognostic factors, it is justified to await the possible appearance of metastases. For the future, it is recommended that CXR be omitted from the schedule, and it might be feasible to discontinue follow-up evaluations after 5 years.

Abstract
Eight patients with non-seminomatous testicular cancer relapsing after primary chemotherapy were treated with salvage chemotherapy consisting of high-dose methotrexate (12 g/m2), vincristine (1.2 mg/m2) weekly for four weeks, followed after an interval of four weeks by 3 times 100 mg/m2 cisplatin (50 mg/m2 on day 1 and 2) every 10 days. This regimen resulted in 2 partial (PR) and 2 complete responses (CR). The two patients achieving CR remain disease-free for 43+ and 53+ months. Toxicity was mainly methotrexate-related and could be ameliorated to a large extent by leucovorin rescue. This small study shows that methotrexate, vincristine, followed by cisplatin is effective in the treatment of relapsed non-seminomatous testicular cancer at the cost of manageable toxicity.

Abstract
Aggressive fibromatosis is a rare soft tissue tumour with a high tendency to local recurrence, even after apparently adequate resection. Wide local excision with a margin of at least 3 cm, depending on the anatomical location, should be performed to improve rates of recurrent disease. There is no consensus concerning the role of radiotherapy in the treatment of these lesions. The clinical findings of 39 cases diagnosed between 1972 and 1991 were reviewed retrospectively. Local control was effected in 19 of 32 patients treated with surgery alone after a median (range) follow-up of 72 (18-236) months. There were 40 cases of recurrent fibromatosis in 15 patients. Local control was obtained in 13 of 14 patients who received radiotherapy using a wide-field technique and doses of more than 50 Gy over a period of 5 weeks after marginal or incomplete resection of primary or recurrent lesions (P < 0.001). The results suggest that in a selected group of patients with aggressive fibromatosis radiotherapy may effectively achieve control of residual disease after surgery without marked disfigurement and loss of function.

Abstract
Recombinant tumor necrosis factor alpha (rTNF alpha) has potent antitumor activity in experimental studies on human tumor xenografts. However, in humans, the administration of rTNF alpha is hampered by severe systemic side effects. The maximum tolerated dose ranges from 350 to 500 mg/m2, which is at least 10-fold less than the effective dose in animals. Isolated perfusion of the limbs (ILP) allows the delivery of high-dose rTNF alpha in a closed system with acceptable side effects. A protocol with a triple-drug regimen was based on the reported synergism of rTNF alpha with chemotherapy, with interferon-gamma, and with hyperthermia. In patients with melanoma-in-transit metastases (stage IIIA or AB), we obtained a 91% complete response rate compared with 52% after ILP with melphalan alone. In unresectable soft tissue sarcomas, this protocol was found to produce a 50% complete response with 87.5% limb salvage, since most tumors became removable. Release of nanograms levels of TNF alpha in the systemic circulation was evident, but control of this leakage and appropriate intensive care resulted in acceptable toxicity. Angiographic, immunohistological, and immunological studies suggest that the efficacy of this protocol is due to a dual targeting: rTNF alpha activates and electively lyses the tumor endothelial cells, while melphalan is mainly cytotoxic to the tumor cells. ILP with rTNF alpha appears to be a useful model for studying the biochemotherapy of cancer in man.

Abstract
This study was performed to determine the changes in pulmonary function in patients randomised to receive treatment with four cycles of bleomycin, etoposide and cisplatin (BEP) (27 patients) or with four cycles of etoposide and cisplatin (EP) (27 patients) for disseminated non-seminomatous testicular cancer. This enabled us to establish whether effects other than those due to bleomycin determined the detrimental effects of BEP on lung function assessments. Slow inspiratory vital capacity (VC), the transfer factor of the lungs for carbon monoxide (TLCO), the diffusing capacity of the alveolo-capillary membrane (Dm), the pulmonary capillary blood volume (Vc) and the transfer factor of the lungs for carbon monoxide per unit alveolar volume (KCO) were determined before and at 3 week intervals during chemotherapy. Both groups, similar in terms of factors that may influence pulmonary function, showed during therapy a significant decrease in TLCO compared with the pretreatment value. Only at the end of the therapy was a significant difference in TLCO between both groups observed. Dm diminished also significantly in both groups during treatment, but differences between both groups were not seen. VC and Vc decreased in patients receiving BEP but remained constant during treatment with EP. It can be concluded that the Dm, KCO, and the widely used TLCO are not suitable parameters to monitor specifically pulmonary toxicity induced by bleomycin as part of a multidrug regimen. However, VC and Vc appear to be proper lung function assessments which reflect specifically alterations induced by bleomycin.

Abstract
The aim of this study was to investigate the role of mild hyperthermia (39-40 degrees C) in isolated cytostatic perfusion for patients with recurrent melanoma of the extremities. A total of 218 patients treated with mild hyperthermic perfusion was compared to 166 patients perfused under controlled normothermic conditions (37-38 degrees C). Only patients whose lesions had been excised before or at the moment of perfusion were eligible for this study. A variety of prognostic factors was controlled for in a Cox proportional hazards analysis. The application of mild hyperthermia did not influence limb recurrence-free interval nor survival (corrected P values 0.46 and 0.18, respectively). In this retrospective comparative study, no benefit for mild hyperthermia in regional isolated perfusion could be identified.

Abstract
Combinations of dacarbazine (DTIC) and other cytotoxic agents or alpha-interferon were given to 136 patients in five different regimens. The total response rate was 32% (95% confidence interval 24-40%); 13% had a complete remission. Female patients had a significantly higher chance of response than male patients: 46% vs 23%. There was also a difference in complete response rate: 25% vs 9%. The overall survival was 6 months; 8% of patients had a response of more than 6 months and 2% of more than 2 years. Although response rates vary among the various regimens described in the literature, the complete response rates are quite similar and the long-term disease-free survival of these combinations may be similar to that of dacarbazine alone.

Abstract
Chondrosarcomas are a heterogeneous group of bone neoplasms of which the basic neoplastic tissue is cartilaginous. Frequently the histologic diagnosis and grading of chondrosarcomas is difficult and the histologic appearance does not always reflect the biologic behavior of these tumors. Therefore, it is important to find other parameters that can be of help in the proper diagnosing and grading of these neoplasms. To this end, we attempted to correlate the chromosomal pattern of chondrosarcomas to their histologic subtypes and grades. The cytogenetic analysis of two intermediate-grade chondrosarcomas of bone, and a review of the literature, are presented.

Abstract
BACKGROUND Isolated regional perfusion (IRP) of an extremity is a major operation. The therapeutic value for stage I melanoma is still controversial and is presently being investigated in a prospective, randomized study by the European Organization for Research and Treatment of Cancer. So far there are no reliable data available concerning the morbidity of IRP. Therefore, we performed a prospective, randomized study on this topic. METHODS In a prospective study, a group of 97 patients with a stage I melanoma localized on an arm or leg were randomized for IRP with melphalan followed by wide excision (WE) and fasciotomy or for WE only. Morbidity was evaluated on the basis of the following parameters: duration of hospitalization, postoperative pain, postoperative performance, and grade of perfusion toxicity. At 12-month follow-up, a physical diagnostic examination was performed to measure the mobility of the joints, and the circumference and volume of the treated and untreated extremities. RESULTS All the parameters, including the physical diagnostic examination, could be evaluated in 83 of the 97 patients (8 patients died of metastatic disease and 1 patient died of another disease before they could be investigated; 2 patients were in too poor physical condition due to metastases to be examined, and 3 patients were unable to participate for nonmedical reasons). Age and sex distribution were comparable in the various patient groups. Treatment mortality was 0%. There were no complications except for urine retention (one patient) and wound dehiscence (one patient). After IRP + WE of the lower limb, the period of hospitalization was an average of 1.9 days longer (p = 0.01) than for WE on the limb only. This difference was absent for the arm. Naturally after perfusion, there was a significant difference in toxic reactions (edema and pain) between the IRP + WE patients and the WE-only patients. However, at 12-month follow-up, the difference in morbidity between IRP + WE and WE-only patients was no longer present: Morbidity of joints and circumference of the limb were the same. A number of subjective complaints were encountered fairly often after IRP + WE (e.g., pricking sensations or pain during changes in the weather), which can possibly be explained by fibrosis caused by perfusion. These complaints were not quantified further because they did not hinder the patients' functioning. CONCLUSIONS In a long term, IRP with fasciotomy does not cause any additional morbidity. Immediately after the operation, there was more morbidity as a result of the perfusion, which caused a 2-day-longer period of hospitalization in the patients with lower-limb perfusion compared with those who underwent WE only. These findings are in contrast to those in the literature, in which 25% limitation of motion in the ankle joint after perfusion is mentioned. One explanation may be that we always performed fasciotomy after perfusion to prevent (sub)clinical compression syndrome and avoid late fibrosis.

In melanoma-in-transit metastases (stage IIIA or AB) we obtained a 91% complete response compared with 52% after ILP with melphalan alone. Leakage and release of nanograms levels of TNF alpha in the systemic circulation can be abrogated in most patients by low pump flow, continuous leak monitoring, extensive washout, and limb massage. In case of unavoidable leakage, appropriate intensive care results in minimal toxicity. The ILP with rTNF alpha appears to be a useful model for studying the biochemotherapy of cancer in humans.

Abstract
In the present study, we examined the distribution of integrin subunits and extracellular matrix proteins in normal testis, intratubular germ cell neoplasia (ITGCN), and primary and metastatic seminomas. Compared to normal testis in ITGCN, Sertoli cells showed increased expression of alpha 3, alpha 6, and beta 1 integrin subunits. Malignant intratubular germ cells stained for alpha 3, alpha 6, and beta 1 integrin subunits. Progression of ITGCN to invasive seminoma was associated with loss of alpha 3 integrin subunit expression by tumor cells. Consequent to this loss, it can be speculated that the strong expression on ITGCN may be related to the noninvasive character of the lesion as is also known from other noninvasive tumors. All tumors showed a strong expression of alpha 6 and beta 1 integrin subunits. The alpha 5 integrin subunit was weakly expressed in primary seminomas in all stages. No differences were observed in integrin expression between primary and metastatic tumors. The distribution of extracellular matrix proteins was heterogeneous and revealed clear architectural differences between seminomas that may reflect different stages of tumor stroma formation. To our knowledge, the results presented in this study provide the first information on the possible role of tumor-extracellular matrix interactions in the biological behavior of ITGCN and testicular seminomas.

Abstract
To define the activity of an individually escalated dacarbazine (DTIC) dose combined with interferon-alpha-2a (IFN), granulocyte-colony stimulating-factor (G-CSF) and ondansetron, 20 patients (pts) with metastatic melanoma were treated with DTIC, ondansetron 8 mg iv, G-CSF 300 micrograms sc and IFN 9 MU sc. Treatment was performed every 21 days to a maximum of 6 courses. DTIC dose was escalated with 250 mg/m2 in case of acceptable toxicity to 1250, 1500 and 1750 mg/m2 in (projected/realized), 14/19, 8/11 and 0/5 pts, respectively. Dose escalation prohibiting toxicities were thrombocytopenia (10 pts), leukopenia (9 pts), and nausea/vomiting (2 pts). Four partial remissions were observed, for a response rate of 20% (95% confidence interval, 6 to 44%). Duration of responses was 1, 2, 3 and 3 months. Median overall survival was 8 months.

Abstract
We report an update of a multi-centre pilot study previously published. Fifty-three patients (42 women, 11 men) were accrued between October 1988 and May 1992: 34 had stage IIIA, 15 had stage IIIAB, and four had stage IV melanoma. Most of them had more than five in-transit metastases; 50% had been previously treated by regional chemotherapy. Protocol included 90-min isolation perfusion at 40 degrees C with 2-4 mg rTNF-alpha, 0.2 mg rIFN-gamma and 10/13 mg/l melphalan. We prevented severe TNF systemic side effects by administration of dopamine and fluid loading. There has been no toxic death and the toxicity remained acceptable, with only one multi-organ failure (MOF) and no prolonged shock. Response rates remained very high, with 90% complete remission, 10% partial response and no failure. With a median follow-up time of 26 months, there were 12 regional recurrences, 15 distant metastases and nine local and distant recurrences. The median overall survival has been 28 months. We conclude that high-dose rTNF-alpha associated with melphalan in isolation perfusion is the therapy of choice for in-transit melanoma metastases.

Abstract
A malignant bone tumour may develop in the femur of a child. In the majority of cases it will be necessary to resect the bone involved, growth plate and adjacent tissues. A modular endoprosthetic system has been developed which can be extended non-invasively to bridge the defect resulting from such a resection. Elongation is achieved by using an external magnetic field. In vitro tests with a prototype showed that the lengthening element met all requirements. Six animal experiments showed that the lengthening element also functioned in vivo.

Abstract
METHODS The treatment of a patient with soft-tissue sarcoma was evaluated with FDG-PET. A limb-saving complete remission of a locally advanced liposarcoma of the left thigh was achieved with isolated regional perfusion of the limb with tumor necrosis factor alpha, interferon gamma and melphalan. RESULTS PET with 18F-FDG before perfusion showed high glucose consumption in the tumor. After perfusion, glucose metabolism in the tumor was absent. Subsequent excision confirmed complete necrosis of the tumor. CONCLUSION FDG-PET may be useful in evaluating the results of isolateral regional limb perfusion for soft-tissue sarcomas.

Abstract
The majority of patients with soft tissue sarcoma (STS) or bone sarcomas (BS) of the upper limb can be treated today with limb saving procedures using combined modality therapies. However, for a small group of patients the interscapulothoracic (IST) amputation is the only final surgical treatment with either a curative or a palliative intent. Since 1972, 12 patients seven males and five females, median age 36 years (range 13-82) underwent an interscapulothoracic amputation; five for bone sarcomas, five for soft tissue sarcoma and two for locoregional metastases. There was no post-operative mortality or morbidity. During a median follow-up of 8 years (range 0.25-15), there was no local recurrence. The five-year survival rate for the soft tissue sarcomas was 80% and for the bone sarcomas 30%. The interscapulothoracic amputation is one of the major ablative surgical procedures which should be performed with curative intent, very rarely with a low palliative intent. The prognosis of an interscapulothoracic amputation for shoulder girdle malignancies is not different from extremity soft tissue sarcomas or bone sarcomas located more distally. The morbidity and local recurrence rate after interscapulothoracic amputation should be negligible.
