Twenty cases of Ewing's bone tumor, seen at the Orthopaedics Clinic of Padua from 1958 to 1975, were classified into two groups on the basis of results obtained from different schemes of treatment. In the first group of patients, treated during the period 1958-69 by surgery and irradiation, the mean survival rate was one year with two exceptions still surviving since 17 and 11 years respectively (treatment: only amputation). The mean survival rate was prolonged to 5 years in the second group. Here, combined treatment included irradiation (4.000-6.000 r), medical treatment (Adriamycin, CCNU, Vincristine) vaccine therapy and surgery. In the Author's opinion it is more convenient to use the latter therapeutic approach because of the promising results, the improved survival rate and the more effective control of relapses and metastases.

Eight cases of clear cell sarcoma of kidney were seen in the Department of Pathology, University Hospital, Kuala Lumpur, Malaysia over the 16-year period from 1973 to 1989. Five of the patients were males. Six patients were Malay, one Chinese and one Indian. The patients' ages ranged from 8 months to 3 years. Clear cell sarcoma was the original diagnosis in two patients while six were diagnosed as blastemal-predominant Wilms' tumours at presentation. Metastases developed in five patients. Metastatic sites included the thoracic vertebra, skull, orbit, humerus, radius, ulna, shoulder, lung and liver. The prolonged survival, of 9 years and 9 months, seen in one patient despite omission of Adriamycin (doxorubicin) from the chemotherapeutic protocol is highlighted. We also emphasise the histological factors which are of help in differentiating clear cell sarcoma from Wilms' tumour.

The formation of a blood supply (angiogenesis) is critical to the growth of solid tumors. The naturally occurring steroid tetrahydrocortisol, the synthetic cyclodextrin derivative beta-cyclodextrin tetradecasulfate, and the tetracycline derivative minocycline have antiangiogenic activity. Tetrahydrocortisol and beta-cyclodextrin tetradecasulfate in a 1:1 molar ratio by continuous infusion over 14 days and minocycline administered i.p. over 14 days from day 4 to day 18 postimplantation of the Lewis lung carcinoma significantly increased the growth delay of the primary tumor after treatment with cis-diamminedichloroplatinum(II), melphalan, cyclophosphamide, Adriamycin, bleomycin, and radiation therapy administered in standard regimens. Addition of the antiangiogenic agents to treatment with the cytotoxic therapies not only reduced the number of lung metastases formed from the primary tumor but also reduced the number of large metastases. Five of 12 animals treated with the antiangiogenic modulators and cyclophosphamide were long-term survivors (> 120 days). Thus, antiangiogenic therapies can potentiate the efficacy of standard anticancer therapies.

We have treated advanced transitional-cell carcinoma of the urothelial tract with methotrexate, vinblastine, Adriamycin, and cisplatin (M-VAC) chemotherapy since July of 1985. We analyzed the effect of that chemotherapy in 26 patients with advanced urothelial cancer who were treated in our hospital and followed up. They were divided into two groups. Group 1 consisted of 15 patients with distant metastases. In all, 11 of them received M-VAC as adjuvant chemotherapy for metastatic lesions after surgical removal of the primary lesion, and the remaining 4 patients were not operable since they had very advanced-stage tumors; they received only M-VAC chemotherapy. Group 2 contained 11 patients who received M-VAC neo-adjuvant chemotherapy. In group 1, the overall response rate was 57.1% and the mean duration of response was 12.6 months. In the 11 patients who had received M-VAC as adjuvant therapy after surgical removal of the primary tumor, the mean duration of response was 14.1 months. After M-VAC chemotherapy, six patients underwent surgical resection of metastatic lesions and restaging was done pathologically in these cases. The clinical response coincided with the pathological response in all six cases. In group 2, 5 of 11 patients experienced histological downstaging of the resected bladder. M-VAC chemotherapy combined with surgical resection of residual tumors has proved to be an effective option against advanced urothelial cancer.

Attempts were made to identify factors related to the response of patients treated with intravenous methotrexate, vinblastine, Adriamycin, and cisplatin (M-VAC). The subjects consisted of 54 patients with advanced urothelial cancer whose histological type was transitional-cell carcinoma. The effects of various factors on the response were studied using univariate analysis and a multiple logistic regression model. The following factors were included in the analyses: (1) age, (2) sex, (3) performance status (PS), (4) primary site, (5) histological grade, (6) T category, (7) N category, (8) M category, (9) tumor status, and (10) dose of drugs. In all, 9 patients achieved a complete response and 23 showed a partial response, for an overall response rate of 59% (95% confidence limits, 46%-72%). Univariate analysis revealed that the PS, M category, and dose of drugs were related to the response, and there was a significant correlation among these three factors. In the multiple logistic regression model, the absolute value of t was high for the M category. The presence of distant metastases is an important factor in predicting poor efficacy for the present regimen. The management of metastatic disease will be the subject of further study in the treatment of advanced urothelial cancer.

Between 1985 and 1990, 50 patients with unresectable liver metastases from colorectal cancer and 34 subjects with metastases from gastric cancer were treated by repeated hepatic arterial infusion chemotherapy employing an implantable prot system. A catheter was inserted into the hepatic artery via the left subclavian artery and was connected to the implantable injection port in each patient. 5-Fluorouracil (5-FU) at 330 mg/m2 per week (167 mg/m2 daily given continuously over the initial 3 months for colorectal cancer), Adriamycin (ADR) at 20 mg/m2 every 4 weeks and mitomycin C (MMC) at 2.7 mg/m2 every 2 weeks were given to all 34 patients with gastric cancer and to 31 of the colorectal cancer patients. The remaining 19 patients with colorectal cancer received 5-FU at 1,000 mg/m2 every week. As a rule the treatment was performed on an outpatient basis. The side effects and complications observed included myelosuppression (23%), hepatic arterial occlusion (21%), and gastroduodenal mucositis (12%), although no major toxicity was encountered. The response rate (CR+PR) among the evaluated patients as determined using CT scans was 67% for colorectal cancer and 73% for gastric cancer. The overall median survival was 12 months and 15 months, respectively. Good local control of liver metastases from the colorectal and gastric cancers was achieved by repeated hepatic arterial infusion chemotherapy employing an implantable port system without the need for hospitalization and without producing major toxicity. Thus, the implantable port system is very useful for the management of patients with unresectable liver metastases.

Antiblastic chemotherapy of the urological tumors proves to be effective in germ-cell testicular tumor, in bladder cancer and in penis cancer, while a real effective anti-cancer therapy for prostatic and renal cell cancer has not found yet. There is not a significant difference between BVP and BEP regimens as first-line treatments of the good risk germ-cell testicular tumors. On the contrary BEP showed a lower toxicity and an higher efficacy in the treatment of the poor risk patients. Considering salvage therapies, PEI regimen proves to be as the most effective, also in the management of patients pretreated with BEP; high dose chemotherapy with autologous bone marrow transplant is currently examined as third-line therapy. In the treatment of bladder cancer the most effective drugs are Methotrexate, Adriamycin, Vinblastine and Cyclophosphamide, that, when combined, are sensitively more efficacious. The different chemotherapies achieved elevated percentage of Complete and Partial Responses (CR+PR): however these results are maintained in only 10% of the cases. So far the aim of the last studies is to improve the results both with a modification of posology and of the schedule of administration, and with the employ of growth-factors to reduce toxicity. An appreciable improvement in the treatment of locally advanced penis cancer has been achieved employing VBM regimen as adjuvant therapy, especially for patients with extrinsic lymph-nodal metastases, who underwent bilateral inguinal and iliac lymphadenectomy.(ABSTRACT TRUNCATED AT 250 WORDS)

Development of multidrug-resistance (MDR) remains a major cause of failure in the treatment of cancer with chemotherapeutic agents. In our efforts to explore alternative treatment regimens for multidrug-resistant tumors we have examined the sensitivity of MDR tumor cell lines to lymphokine activated killer (LAK) cells. Adriamycin (ADM) resistant B16-BL6 melanoma, L1210 and P388 leukemic cell lines were tested for sensitivity to lysis by LAK cells in vitro. While ADM-resistant B16-BL6 and L1210 sublines were found to exhibit at least 2-fold greater susceptibility to lysis by LAK cells, sensitivity of ADM-resistant P388 cell was similar to that of parental cells. Since ADM-resistant B16-BL6 cells were efficiently lysed by LAK cells in vitro, the efficacy of therapy with LAK cells against the ADM-resistant B16-BL6 subline in vivo was evaluated. Compared to mice bearing parental B16-BL6 tumor cells, the adoptive transfer of LAK cells and rIL2 significantly reduced formation of experimental metastases (P less than 0.009) and extended median survival time (P less than 0.001) of mice bearing ADM-resistant B16-BL6 tumor cells. Results suggest that immunotherapy with LAK cells and rIL2 may be a useful modality in the treatment of cancers with the MDR phenotype.

While significant improvements have been made in the management of localized soft tissue sarcomas, enabling the realization of better functional results and a better overall outcome, progress in metastatic disease has been less than impressive. Adriamycin and DTIC based chemotherapy programs have resulted in response rates of upto 50%, with a small but finite cure fraction, especially in conjunction with surgical resection of residual abnormalities. The decade of the 80s experienced a considerable amount of enthusiasm in exploring the role of ifosfamide and mesna, and identified its definite usefulness as an effective salvage regimen with response rates of approximately 25%-30% in adriamycin failures. Studies evaluating the role of ifosfamide as up-front line agent in combination with adriamycin have met with increased toxicities without a significant additive therapeutic benefit, probably as a result of compromised dose intensity of each individual agent. The steep linear log-dose response relationship of alkylating agents and adriamycin constitutes the theoretical rationale for use of higher doses of chemotherapy, which have become feasible, with the advent of growth factors for bone marrow support. While this approach seems promising in its infancy, with improved complete and overall response, its ultimate effect on survival is anxiously awaited. The limited experience available in the literature with even more aggressive approaches like marrow ablative doses of chemotherapy followed by bone marrow transplantation, have been uniformly disappointing, with extremely short lived responses and extremely high morbidity and cost. As clinical research continues to improve our understanding and ability to implement the currently available therapeutic armamentarium, the search for newer and better drugs needs to continue.(ABSTRACT TRUNCATED AT 250 WORDS)

Between 2/87 and 2/91, 49 women with operable breast cancer involving greater than or equal to 10 axillary nodes were treated following mastectomy, with four cycles of Cyclophosphamide, Adriamycin, 5FU, followed by high doses of Cyclophosphamide, Cisplatin, Carmustine (HDCT) with autologous bone marrow transplant support. Forty patients received local-regional radiotherapy (generally to the chest wall, internal mammary, supraclavicular, +/- axillary nodal areas; minimum 44-50 Gy, 1.8-2 Gy/fraction, +/- 10-15 Gy scar boost; standard radiation techniques). The first nine patients did not receive local-regional radiotherapy. Three developed a local-regional failure (6-12 months after HDCT); six are without evidence of disease. Local-regional radiotherapy (LR XRT) was delivered to the subsequent 40 patients following HDCT+autologous bone marrow transplant. Six received less than 44 Gy of the planned local-regional radiotherapy due to significant toxicity and one of these failed locally. Only one local failure was observed among the 34 patients who received greater than or equal to 44 Gy. Two additional patients developed distant metastases. None of these 40 patients have failed in the axilla despite the fact that the axilla was irradiated in only 18 cases. Overall, 36/40 (90%) of these patients are without evidence of disease 4-30 months following HDCT (approximately 10-36 months after mastectomy, median 22 months). Radiotherapy was interrupted or discontinued because of progressive dyspnea, thrombocytopenia, or neutropenia in nine patients. Further studies to determine the roles of local-regional radiotherapy and HDCT in the development of these toxicities are underway. These encouraging results suggest that HDCT + autologous bone marrow transplant+local-regional radiotherapy may improve the survival rate in these high risk patients. A national randomized study to test the efficacy of this HDCT regimen is currently underway (Cancer and Leukemia Group B#9082 and Southwest Oncology Group #9114).
