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)

An advanced breast cancer patient refractory to CAF (Cyclophosphamide,
Adriamycin
, 5-fluorouracil), 5-FU-Methotrexate sequential therapy and Tamoxifen was treated with the combination 5' DFUR, MMC, Etoposide and MPA. Complete response was obtained both against liver and lymph node
metastases
from 7 months after the initial treatment. A mild bone marrow suppression and appetite loss were observed as the side effect. It is suggested that the combination therapy may be useful for previously treated patients with advanced breast cancer.

The Radiation Therapy Oncology Group (RTOG) conducted a Phase I/II study in hepatocellular cancer that closed on September 9, 1987 and some results presented previously. Here, 17 patient characteristics are evaluated to identify any of prognostic significance. Two hundred sixteen patients were entered and 198 (74% with
metastases
and/or previous chemotherapy) were evaluable. Treatment began with an induction regimen of external beam radiotherapy to the liver (21.0 Gy, 3.0 Gy/Fx, 10 MV photons, 4 days per week) with low-dose chemotherapy (5-Fluorouracil (FU), 500 mg, i.v.; Doxorubicin, 15 mg, i.v.) on treatment Days 1, 3, 5 and 7. In the later stages of these studies, 56 patients received external beam radiotherapy as hyperfractionated treatment (1.2 Gy twice daily, 4 hours separation, 5 days per week, 24.0 Gy total) with similar chemotherapy. One month following induction therapy, cycles of radiolabeled antibody therapy were given every 2 months. Each cycle was derived from a different species of animal and consisted of 30 mCi I-131 antiferritin, Day 0, and 20 mCi, Day 5. On Day -1, 5-FU, 500 mg, and
Adriamycin
, 15 mg, were administered. The overall median survival for the entire group, including previously treated patients, was 4.9 months. The median survival for alpha-fetoprotein (AFP) - patients not previously treated was 10.5 months. Median survival for all AFP - patients was 8.5 months and for all AFP + patients was 4.6 months (p = 0.006). Of the 17 pretreatment characteristics investigated for prognostic value Karnofsky Performance Score (KPS) (80-100 vs. less than 80) (p = 0.0001), presence/absence of ascites (p = 0.0002), bilirubin level (less than 1.5 vs. greater than or equal to 1.5) (p = 0.018), SGOT (less than or equal to 35 vs. greater than 35) (p = 0.001); alkaline phosphatase (less than or equal to 95 vs. greater than 95) (p = 0.008) were found to be significant independently using a multivariant regression model. The relative risk of dying for the unfavorable component of each of these characteristics was 2.2, 2.0, 1.5, 1.9 and 1.7, respectively. Good and poor prognostic groups were then defined and compared to a similar patient population (RTOG study 83-19) with confirmation of the validity of the model. When stratification for these overpowering clinical factors was incorporated, AFP status was again significant with a relative death rate 1.80 times higher for AFP+ patients. Our recommendations for structuring future prospective randomized trials are discussed and include stratification by AFP status.

Rapid advances in the understanding of Wilms' tumor (WT) and its management are being made both in the laboratory and the clinic. Molecular genetic research has implicated loss of a tumor suppressor gene on the short arm of chromosome 11 as one of the pathways responsible for the development of the neoplasm. Preconception maternal (hair dyes) and paternal (occupation) exposures to environmental agents have been the subject of epidemiologic studies of possible risk factors. Histopathologic analyses have identified several different and less common tumor types among those previously aggregated under the WT rubric. WT itself has been subdivided into the so-called favorable histology (FH) and anaplastic forms, the prognosis being worse for the latter. Clinical research has standardized management by surgery, chemotherapy, and radiation therapy (RT) and furthered the identification of risk factors. Patients can now be stratified according to tumor type and stage, and the intensity of treatment modulated accordingly; eg, RT at low doses is used in only 25% of National Wilms' Tumor Study (NWTS) patients without distant
metastases
. Before the NWTS, it had been given to almost all and at higher doses. Chemotherapy, whether given pre- or postoperatively, is based on dactinomycin and vincristine with
Adriamycin
[( ADR] doxorubicin; Adria Laboratories, Columbus, OH) added for high-risk patients. The currently used NWTS combined modality therapy for WT patients has dramatically improved survival rates; 95% now are alive 2 years after treatment. Remaining questions are the identification of the late effects of the treatments used and the further refinement of therapy to reduce iatrogenic complications to a minimum.

Two hundred and fifty evaluable patients with breast cancer entered a protocol combining neoadjuvant and consolidation therapy by vinblastine (V), thiotepa (T), methotrexate (m) and 5-fluorouracil (f) (VTMF) with or without
Adriamycin
(A) (Doxorubicin; Adria Laboratories, Colombus, OH USA), and radiation therapy as exclusive locoregional treatment. Tamoxifen was given to 195 patients, 130 post menopausal and 65 pre-menopausal, and was omitted in 55 patients (31 postmenopausal and 24 pre-menopausal). There were 19 stage I, 86 IIa, 51 IIB, 36 IIIA and 58 IIIB. Primary chemotherapy induced tumor volume regression of more than 75% in 41% of the patients and complete clinical regression in 30% of the patients. The 5 years DFS rates were 100% for stage I, 82% for stage IIA, 61% for stage IIB, 46% for stage IIIA and 52% for stage IIIB patients. Among the 72 primary relapses there were 39 distant
metastases
, 6 locoregional and distant metastasis and 27 isolated locoregional
metastases
. The actuarial rate of locoregional recurrence is 13% for T2, 18% for T3, 19% for T4. At 5 years the rate of breast preservation was 94%. Cosmetic results are excellent or good for most patients. The 5 years overall survival (OS) were 95% for stage I, 94% for stage IA, 80% for stage IIB, 60% for stage IIIA and 58% for stage IIIB. In multivariate analysis tumor regression appears as an independent and significant factor. This parameter should be preserved in many patients with infiltrative breast cancer.
