A randomized study was conducted to determine the effect of cyclophosphamide on the rate of recurrence and metastases in children with localized and regional neuroblastoma. One hundred and thirty-four patients were entered and 113 were suitable for analysis. All patients had surgical resection of the primary tumor when possible, postoperative irradiation to the tumor bed when indicated for gross residual disease, and 49/113 received cyclophosphamide, 10 mg/kg/day orally for 7-10 days every 28 days for 1 year. A difference was found in the rate of metastases between the patients who did and did not receive chemotherapy; the overall survival of about 80% in both groups was better than anticipated. All relapses occurred during the first year; there were none in 27 Stage I patients, 8/52 in Stage II and 13/34 in Stage III. Toxicity was minimal, with only two patients developing hemorrhagic cystitis that prevented continued therapy.

In 409 sufferers from various malignant tumours, we used the cytostatic Ifosfamide (ASTAZ4942) in fractionated doses. The total i.v. dose averaging 300 mg/kg bodyweight, was either spread over 5 consecutive days (5 X 60 mg/kg i.v.) or over 10 consecutive days (10 X 30 mg/kg). At the same time, most patients were irradiated, the radiation dose usually being only one tenth the antitumour dose. Infections and electrolyte imbalance were first treated before Ifosfamide therapy was instituted. Cases of advanced cerebral sclerosis, thrombopenia below 75,000/cmm, cerebral metastases, impaired renal function and inadequate cooperation of the patient were excluded from the studies. To prevent and control side effects, various premedications and adjuvants are required: Antiemetics, prevention of cystitis and infections, cardiovascular agents etc. Corticosteroids are contraindicated. Out of 360 assessable patients 101 had a full remission, 150 a partial remission, 79 were failures; 30 cases were not evaluated. Good results were seen especially in ovarian carcinoma, mammary carcinoma and microcellular bronchial carcinoma. Particularly striking is the drug's effectiveness in testicular tumours including teratomas, osteosarcomas, chondrosarcomas and myosarcomas as well as in some adenocarcinomas of the gastro-intestinal tract, particularly pancreatic carcinoma. In lymphoreticular tumours and haemoblastoses, its potency is less pronounced. The side effects of Ifosfamide are the same as those of other alkylating agents. They are reversible and can usually be controlled or even avoided by adequate preventive measures. In the order of incidence we observed: Alopecia, leukopenia, fall in haemoglobin, cystitis, intercurrent infections, nausea and vomiting as well as cerebral disorders. Since haemorrhagic cystitis considerably interferes with Ifosfamide treatment, its prevention is of essential importance. Because of possible complications and specific premedication and adjuvant measures for their control, this type of treatment should for the present only be carried out by oncologists or special cancer centres.

Vincristine, actinomycin D, and cyclophosphamide (VAC) were administered to 14 patients with Ewing's sarcoma. The primary tumors were treated with radiation therapy and concurrent chemotherapy. Nine patients had no visible metastases at diagnosis: two died following the development of pulmonary metastases and the rest have been free of disease for periods varying from 4 months to 4 1/2 years following completion of treatment. This contrasts with a 27% survival in patients previously treated at this center with single agent chemotherapy. Five other patients had demonstrable metastases at diagnosis: VAC chemotherapy achieved complete regression of pulmonary metastases in three for 9, 9+ and 24+ months, respectively. Following disappearance of tumor in the latter two, pulmonary irradiation was administered in an attempt to consolidate the response, but tumor recurred 6 months later. These patients eventually died of widespread disease although survival appeared prolonged in comparison to that seen in past experience. Chemotherapy was well tolerated, although three patients developed hemorrhagic cystitis, necessitating discontinuation of cyclophosphamide. The data suggest the potential for prolonged control and an increase in the cure rate with this therapeutic approach.

A total of 356 patients with recurrent superficial transitional cell carcinoma of the bladder was entered in a randomized clinical trial to compare intravesical thiotepa, doxorubicin and cisplatin with respect to the recurrence rate and disease-free interval. After complete transurethral resection of all visible lesions, the drugs were administered weekly for 4 weeks and monthly for 11 months. The recurrence rates per year were 0.50 for thiotepa, 0.54 for doxorubicin and 0.58 for cisplatin. Of 266 patients (mean followup 41 months) 35 reported an increase in T category and 19 of them had distant metastases. No association between treatment and progression was noted. Thus, there is no difference among treatments with respect to efficacy. However, severe anaphylactic reactions were observed in the cisplatin arm and chemical cystitis was more frequently reported in patients who received doxorubicin.

A 63-year-old Japanese man complained of hematuria and pollakisuria for several months. Computed tomography and cystography disclosed an infiltrative tumor mass in the irregularly thickened apical and posterior walls of the urinary bladder. Narrowing of the vesical lumen and posterior extension of the tumor into the pelvic cavity were also noted. After palliative ureterocutaneostomy, 60 Gy irradiation was given locally. The patient died of cachexia seven months later. Autopsy revealed neuroendocrine carcinoma of the urinary bladder with extensive invasions and metastases to the pelvic and peritoneal cavities, liver, lungs, vertebrae, left kidney and retroperitoneal lymph nodes. Histologically, atypical tumor cells with eosinophilic cytoplasm formed solid nests and anastomosing cords with pseudoglandular structures. No other histologic tumor components were included. An intact urachal remnant was found at the vesical apex while features of metaplastic cystitis were absent. In addition to positive carcinoembryonic antigen and cytokeratin, the argyrophilic cancer cells were immunoreactive for neuron-specific enolase, chromogranin A, serotonin, neuropeptide Y, glicentin, somatostatin, neurotensin and calcitonin. Ultrastructurally, neurosecretory-type granules, with a mean diameter of 166 nm, were identified in the cytoplasm of the tumor cells. To discuss the histogenesis of the tumor, 44 previously reported cases of neuroendocrine carcinoma of the urinary bladder were reviewed.

Mitomycin C was given intravesically over periods of 2-32 months to 34 patients with carcinoma in situ of the urinary bladder. Initial complete response was obtained in 17 patients, 14 of whom remained without evidence of disease during follow-up averaging 28 months from cessation of mitomycin therapy. In three responding patients malignant cells reappeared in the urine during follow-up, although no recurrence of carcinoma could be proven in bladder biopsy specimens. In eight of the 17 non-responders, muscle invasion and/or metastatic disease developed during or after mitomycin treatment. The prostatic urethra was involved in five cases. Chemotherapy had to be discontinued because of chemical cystitis in three cases. Mitomycin C appears to be effective for intravesical treatment of carcinoma in situ of the urinary bladder. Close surveillance of these patients is mandatory, however, and must include monitoring not only of the bladder, but also of the prostatic urethra and the upper urinary tract.

One hundred nine newly treated patients with advanced neuroblastoma were entered in this study between January 1985 and May 1989. The eligible patients included infants younger than 12 months of age with Stage IVA disease (bone cortex, distant lymph node, and/or remote organ metastases) and patients aged 12 months or older with Stage III or IV disease (IVA plus IVB with tumor crossing the mid-line and with metastases confined to bone marrow, liver, and skin). The patients first received six cyclic course of intensive chemotherapy (regimen A1), consisting of cyclophosphamide (1200 mg/m2), vincristine (1.5 mg/m2), tetrahydropyranyl adriamycin (pyrarubicin; 40 mg/m2), and cisplatin (90 mg/m2). Original tumors and the regional lymph node metastases were removed some time during these first six cycles of chemotherapy. The patients were further divided into three groups. Patients in course 1 received alternating treatment by regimen B (cyclophosphamide and ACNU) and intensified regimen A1, and those in course 2 were treated with alternating administration of regimen C (cyclophosphamide and DTIC) and intensified A1. Patients in course 3 were treated with bone marrow transplantation (BMT) preceded by high-dose preconditioning chemotherapy. Survival rates were 77% in Stage III and 54% in Stage IV at 2 years, and 70% in Stage III and 45% in Stage IV at 3 years. The major toxicities encountered were bone marrow suppression with leukocyte counts down to 100/mm3, mild cystitis, and hearing impairment. The 2-year survival rate was 78% in 21 patients who underwent BMT when complete remission was achieved. We concluded that our intensive induction chemotherapy is of significant value in increasing the rate of complete response, and in widening the indications for and achieving improved results of treatment with BMT.

Biopsy and autopsy material from the urinary bladder was studied using PAS and PAS-D techniques to identify glycogen and neutral mucins, the alcian blue/high iron diamine method to distinguish sialo- and sulphamucins and the PB/KOH/PAS technique to localize O-acylated sialomucins. All of 10 examples of normal urothelium and both of two cases of transitional carcinoma in situ contained glycogen, but no mucin. Other lesions displayed one of two patterns of mucin production: the extracellular mucin seen focally in 17 cases of cystitis cystica consisted of sialo- and/or neutral mucins only, a pattern also displayed by mucins produced in 10 of 13 examples of transitional cell carcinomas and by three of nine tumours purely or in part adenocarcinomas. The intracellular mucins expressed in five of the 17 cases of cystitis glandularis and in all of eight cases of frank intestinal metaplasia with goblet cells displayed a colonic phenotype, with production of O-acylated sialomucins. A similar profile was expressed by six adenocarcinomas and this included tumours likely to be of vesical and also of urachal origin. It is concluded that identification of O-acylated mucins cannot distinguish between primary bladder tumours and metastases from a colonic primary, or between carcinomas of vesical and urachal origin.

Sixteen patients with hepatic metastases of histologically documented breast cancer were treated with etoposide (VP 16-213) and cyclophosphamide. Previously, 6 had shown relapse in the liver after adjuvant chemotherapy, 2 had failed to respond to another chemotherapy combination, and 8 had never undergone chemotherapy. Fifty percent responded to treatment, including 1 complete remission and 7 partial responses. Median survival was 16 months and median duration of response was 13 months. All patients showed alopecia and moderate leukopenia; 13 experienced moderate gastrointestinal toxicity; there was 1 mild case of anemia and 1 case of moderate hemorrhagic cystitis. This study suggests that the combination of VP 16-213 and cyclophosphamide is a well-tolerated and effective treatment in advanced breast cancer patients with liver metastases.

An ongoing trial of combination chemotherapy using ifosfamide (Holoxan), epirubicin and 5-fluorouracil was started in 1987. A total of 30 patients with metastatic cancer of the breast received 1.5 g/m2 i.v. ifosfamide over 60 min on days 1-3, 50 mg/m2 i.v. epirubicin on day 1 and 500 mg/m2 i.v. 5-fluorouracil on day 1, followed by mesna (Uromitexan) given at 20% of the ifosfamide dose at 0, 4 and 8 h. The courses were repeated every 4 weeks. In all, 198 courses were given, ranging from 3 to 13 (median, 7) cycles/patient. The mean age of the 30 patients was 48 years (range, 35-66 years); 5 had not previously received chemotherapy and the others had failed prior cytotoxic and endocrine therapy. Overall, 28 patients were evaluable, 7 (25%) showed a complete response and 15 (54%) had a partial response, for an overall response rate of 22/28 (79%). Three patients showed stable disease with improved symptoms, and in three cases disease progression occurred. The median duration of response was 9 months (range, 3-20 months). Median survival was 11 months for all patients, 15 months for CRs, 10 months for PRs, 6 months for stable disease and 12 months for progressive disease (PD). Survival for the 22 responding patients was 12 months. Toxicity was acceptable and included alopecia, mucositis, nausea, vomiting, diarrhoea, mild cystitis and myelosuppression. Epirubicin did not appear to produce cardiac toxicity, and ifosfamide with mesna did not seem to result in severe urotoxicity. Chemotherapy with ifosfamide, epirubicin and 5-fluorouracil proved to be effective for treatment of advanced breast cancer and should be further studied in large, controlled trials.
