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

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).

To evaluate the prognosis of patients with Wilms' tumor who have pulmonary densities identified on a computed tomographic (CT) scan of the chest, but have a negative plain chest radiograph, we reviewed the treatments and outcome of 32 patients randomized or followed on National Wilms' Tumor Study (NWTS)-3. The 4-year event-free and overall survival percentages of 18 of these patients who had a favorable histology tumor and were treated as stage IV tumors with three or four drugs plus whole-lung irradiation were 88.1% and 94.0%, respectively. The 4-year event-free and overall survival percentages for nine favorable histology patients treated less aggressively based on the extent of locoregional disease with two or three drugs and without whole-lung irradiation were 88.9% and 88.0%, respectively. There were no statistically significant differences in the 4-year event-free or overall survival percentages between the two groups. The current data do not demonstrate improved survival for favorable histology patients treated with whole-lung irradiation for pulmonary
metastases
identified only on chest CT scan. However, due to the small number of patients included, no statistically valid conclusions regarding the roles of
Adriamycin
(doxorubicin; Adria Laboratories, Columbus, OH) and/or whole-lung irradiation in the treatment of these patients can be drawn from the present analysis. Additional patients need to be systematically studied to determine if these preliminary observations can be confirmed.

Hepatoblastoma deemed surgically unresectable at presentation is fatal unless conversion to resectability is attained. We report a series of six consecutive patients, ranging in age from newborn to 5.75 years with hepatoblastoma unresectable at presentation, either because of size of tumor or its anatomical boundaries, or because of
metastatic disease
. All were treated with preoperative continuous infusions of cis-platinum and
Adriamycin
. All achieved resectability, and there was only one operative death. The five surviving patients are alive and free of disease off therapy. Potential benefit may accrue from preoperative chemotherapy in most cases of hepatoblastoma.

Thirteen patients with soft tissue sarcomas were treated with a combination of intra-arterial
Adriamycin
, conventionally fractionated radiotherapy (2 Gy per day), and conservative surgery (trimodal therapy). Severe acute complications occurred in 10 patients: 3 brachial artery thromboses, 6 delayed wound healing, 4 wound infections, and 3 cases of necrosis of the skin plus subcutaneous tissues. Three patients have developed local recurrence. Five patients are alive, 4 of whom are disease-free, and the median follow up time of surviving patients is 56 months. One has significant impairment of limb function due to joint ankylosis. An additional 2 patients were treated with intra-arterial
Adriamycin
and conservative surgery for local recurrence after previous surgery and radiotherapy; both died of subsequent
metastatic disease
, one having a further local recurrence. One patient with multifocal angiosarcoma was treated with intra-arterial
Adriamycin
and radiotherapy but no surgery, and is alive free of disease 49 months later. The combination of radiotherapy and intra-arterial
Adriamycin
with surgery resulted in significant acute toxicity. This small study has not demonstrated any improvement in local control compared with that expected with conservative surgery and radiotherapy alone.

We have evaluated the effect of 5-fluorouracil 600 mg/m2, doxorubicin ('
Adriamycin
') 40 mg/m2, and Mitomycin-C 4 mg/m2 (FAM) in two groups of patients with adenocarcinoma of the oesophagus, as either a preoperative or primary treatment. Response was assessed by barium swallow, CT scan, and measurement of
metastases
where present. Toxicity was as reported for FAM in gastric cancer. In the operated group 8 of 22 patients (36%) showed a partial response following two courses of FAM. Resection was completed in 20 patients, with six hospital deaths (30%). Of the 14 patients who were discharged from hospital, 8 have died (median 8 months) and 6 are alive at 12 to 27 months, with known recurrence in 1. In the non-operated group 6 of 17 patients (35%) showed a response, one complete, following one to six (mean 4.2) courses of FAM. Fifteen patients have died (median 5 months), and 2 are alive and free from disease at 12 and 17 months. Neoadjuvant therapy with FAM in adenocarcinoma of the oesophagus offers no advantage over surgery alone, although with inoperable disease FAM may be of use in palliation.

The authors used a fibrin clot (FC) as a carrier of an anti-cancer drug (AD) to achieve sustained release of the drug.
Adriamycin
(
ADM
) and cis-platinum (CDDP) were individually encapsulated into an FC, and the profile of release of each AD from the FC-AD was examined in vitro. The FC-AD was placed intra-abdominally in ascites hepatoma AH130-bearing rats, and
ADM
or CDDP solution was intraperitoneally injected (IP) into other cancer bearing rats. The survival time was recorded, and related oncolytic mechanisms were investigated. The release of AD from the FC continued for over 15 days. Sixty-eight percent of the rats treated with FC-AD survived for more than 200 days and evidence of malignancy disappeared. Almost all of the IP rats and non-treated rats died within 20 days; these animals had massive ascites and extensive
metastases
. Immunologic studies confirmed that various tumor immunoresponses were induced in the rats treated with FC-AD. The FC-AD system warrants further study for possible antineoplastic activities in vivo.

In order to improve survival in a disease where the majority of deaths occur from
metastases
, the integration of systemic chemotherapy is crucial. Research efforts must continue to focus on refining case selection criteria, improving complete response proportions, and overcoming drug resistance. The blanket recommendation of a single therapeutic strategy such as radical surgery, chemotherapy, or radiation therapy to all patients is quickly becoming an outdated approach. Refinements in the understanding of the clinical, pathologic, and molecular features of urothelial tumors will ultimately improve case selection. Evaluation of NM23 RNA levels, or DNA ploidy and T138 surface antigen expression, which have been shown to correlate with metastatic potential, may hold important therapeutic implications. The use of hematopoietic growth factors has the potential to improve both the tolerance of chemotherapy and complete response proportions, a prerequisite for cure. A recent report from Japan of granulocyte colony-stimulating factor with MVAC and other chemotherapy regimens for urothelial tumors corroborated an initial report in reducing the duration of neutropenia. However, the dose response curves for most of the known active agents are not well defined and, ultimately, new agents and strategies will be required. Gallium nitrate, when administered by continuous intravenous infusion, has significant single agent activity in cisplatin-refractory patients with 9/31 responses (29%), including 6 CRs (19%) and further studies are warranted. Drug resistance remains a major obstacle, and as the mechanisms are unravelled, more rational therapies can be designed. For example, resistance to
Adriamycin
(doxorubicin; Adria Laboratories, Columbus, OH) and vinblastine, two components in the MVAC regimen, are mediated in part by the MDR1 gene. Attempts are ongoing to identify prospectively those tumors with high levels of expression that may be more amenable to treatment with drugs that are not affected by this mechanism. The neoadjuvant approach allows an in vivo assessment of response to chemotherapy as well as the potential for bladder preservation. In most cases additional therapy directed at the primary is required as clinical understaging is a significant problem and pCR proportions are less than 30%. For some patients, initial surgery followed by treatment based on pathologic criteria may represent a better strategy. In these cases the recommendation for adjuvant treatment potentially limits therapy to a population of patients for whom therapy is essential. Based on available data, this would include patients with positive lymph nodes at the time of surgery. Ideally, patients with invasive bladder cancer should be entered into clinical trials designed to assess the impact of these strategies on survival.(ABSTRACT TRUNCATED AT 400 WORDS)
