We report a case of renal cell carcinoma in a 6-year-old girl. The child had the chief complaints of gross hematuria and abdominal pain. An examination using ultrasound, computerized tomography scans and angiography showed a left renal tumor. Left side radical nephrectomy with lymphadenectomy was performed. Histopathological examination revealed renal cell carcinoma of clear cell type with metastasis to the hilar lymph node. She received postoperative therapy with interferon. Now, 3 years since the operation, she is living without evident recurrence. We reviewed 89 Japanese cases of renal cell carcinoma in children including this case and have discussed symptoms, differential diagnosis and treatments.

A 34-year-old man was admitted in May, 1989 because of severe left upper abdominal pain, which was caused by advanced splenomegaly. On initial examinations, peripheral blood showed leukocytosis (13,400/ml) including 60% hairy cell which also infiltrated in bone marrow (64%). The patient was diagnosed as having hairy cell leukemia (Japanese type) of B-cell lineage. Splenectomy was performed as an initial treatment. The effect of splenectomy was only palliative and transient leukocytosis progressed thereafter. alpha-interferon and bestrabucil (KM 2210) were then adopted for 4 months respectively. The effects were, however, unsatisfactory. Subsequently the patient was treated successfully with 2'-deoxycoformycin (DCF). Complete remission was attained following 12 injections of 7.5 mg/body of DCF during 5 months and durable remission persists for more than 6 months without maintenance therapy. The side effect was minimum.

Recombinant interferon alfa (rIFN-alpha) was given to 31 children with acute lymphoblastic leukemia (ALL) in first on-therapy marrow relapse as the sole treatment (30 megaunits/m2/d intravenously x 10 days) before standard four-drug reinduction and during multiagent continuation therapy (30 megaunits/m2 subcutaneously x 3 consecutive days every 3 weeks). After 10 days of rIFN-alpha, there were two partial remissions (PRs); seven additional patients had either greater than or equal to 25% reduction in the percentage of marrow blast cells or hypoplastic marrow. Two patients had progressive disease with an increase in leukocyte counts. All patients experienced influenza-like symptoms, and there were isolated instances of severe abdominal pain and personality change. Dose-limiting toxicity comprised grade III/IV transaminase elevation (two patients) and syncope with personality change (one patient). Twenty-three of 31 children (74%) subsequently achieved marrow remission using standard agents. One patient was taken off study during teniposide (VM-26) and cytarabine (ara-C) consolidation due to toxicity. Continuation therapy including rIFN-alpha pulse was well tolerated in the remaining children; only one patient required rIFN-alpha dosage reduction (for CNS toxicity). rIFN-alpha toxicity did not necessitate reductions in doses of standard chemotherapy agents or significant delays in therapy. Five patients remain in remission at 26+ to 36+ months; 13 patients relapsed in marrow, one in the meninges (7 months), and one in meninges, mediastinum, and lymph nodes (2 months). Two children were removed from study for marrow transplant. In summary, high-dose rIFN-alpha alone had a modest antileukemic effect. In contrast to the clinical experience with combined rIFN-alpha and chemotherapy in adults, rIFN-alpha given in a pulse-like manner throughout continuation therapy did not compromise the intensity of the standard chemotherapy regimen.

Eight patients with advanced ovarian carcinomas resistant to conventional chemotherapy were injected with interferon (IFN) beta (3 X 10(6) U) intraperitoneally twice a week. Seven subjects had ascites. Side effects included abdominal pain, fever, and constipation, but no hematologic toxicity was observed. Growth of solid tumor lesions was unaffected by IFN beta, with the possible exception of one patient who had stable disease. IFN beta intraperitoneally inhibited completely the formation of ascites in four of seven patients with effusions. Natural killer (NK) cell activity was measured in peripheral blood and tumor-associated lymphocytes (PBL and TAL). Using stringent criteria that included repeated assessment of baseline activity, a clear cut increase in NK cytotoxicity of TAL was detected in two of six subjects from whom TAL could be purified. Augmentation of NK activity was restricted to the peritoneal compartment with no effect on PBL. Studies on biologic response modifiers encompassing an analysis of events taking place at sites directly involved by neoplasia may provide an opportunity for generating information on the in situ regulation of tumor-associated host defense mechanisms in humans.

Therapeutic efficacy and toxicity were evaluated in 28 children with acute lymphoblastic leukemia, in ten with acute nonlymphoblastic leukemia (ANLL), and in 13 with metastatic neuroblastoma. All were refractory to standard chemotherapeutic agents and 25 were refractory to an investigational drug. The initial dose was 12 mg/m2/day and was based on an established maximal dose tolerated in adults. This dose was found to be intolerable in 5 of 5 children with leukemia. Similarly an initial dose of 9 mg/m2/day was intolerable in 4 of 5 patients with leukemia. The starting dose in the next 28 children with leukemia or neuroblastoma was 3 mg/m2. This drug was gradually increased to the highest tolerated dose by 3-mg/m2 increments. Fifteen children with acute lymphoblastic leukemia, 3 children with ANLL, and 2 children with neuroblastoma received the drug daily. Seven patients with ANLL and 7 patients with neuroblastoma received the drug biweekly. Seventeen patients with acute lymphoblastic leukemia, 6 patients with ANLL, and 5 patients with neuroblastoma had an adequate trial of the drug. An adequate trial was defined as a minimum of 5 weeks of therapy unless progressive disease developed. Side effects of the drug were striking and included fever, hypotension, myalgia, bone pain, arthralgia, arthritis, abdominal pain, liver toxicity, thrombocytopenia, and neurotoxicity. No complete remission occurred although interferon levels above 100 units/ml were induced in nearly 50% of the patients.

A Phase II study of poly(I,C)-LC was performed in 28 children and adolescents with acute lymphoblastic leukemia (ALL), 10 with acute nonlymphoblastic leukemia (ANLL), and 13 with metastatic neuroblastoma. All were refractory to standard chemotherapeutic agents and 25 to an investigational drug. Initial doses of 12 mg/m2 and 9 mg/m2 were intolerable. However, 9 mg/m2 was tolerable in the majority of patients when the drug was started at 3 mg/m2 and increased by 3 mg/m2 increments. Fifteen children with ALL, three with ANLL, and two with neuroblastoma received the drug daily. Seven patients with ANLL and seven children with neuroblastoma received the drug biweekly. Twenty-eight patients received an adequate trial, which was defined as a minimum of 5 weeks at the maximal tolerated dose, unless there was progressive disease at the maximal tolerated dose. Side effects of the drug were striking, and included fever, hypotension, myalgia, bone pain, arthralgia, arthritis, abdominal pain, liver toxicity, thrombocytopenia, and neurotoxicity. No complete remissions occurred in spite of interferon levels above 100 U in nearly 50% of patients.

2-Amino-5-bromo-6-phenyl-4(3H)-pyrimidinone (ABPP) was given to 59 patients in a Phase I study. The agent was selected because it is an interferon inducer and an immunotherapeutic agent in animal tumor models. The study was conducted in two phases. In the first phase, the drug was administered as a single oral dose of 25-2,000 mg/m2. In the second part, the highest tolerated dose reached during part one was used as the initial dose in a multiple-dose scheme of treatment. Patients were treated weekly. The dose was escalated each week, starting with a dose of 2 g/m2 and escalating to 3, 4, and 5 g/m2. No cardiac, hematologic, hepatic, or renal toxicity was observed. The most common toxicity was nausea and vomiting, which occurred in 18% of the patients; others were headache (8%), abdominal pain (8%), and diarrhea (6%). No consistent induction of interferon and no major modification of host defense parameters occurred. One patient with malignant melanoma showed evidence of tumor regression. Pharmacologic studies demonstrated a significant decrease in the bioavailability of the drug as it was administered in this study. Further studies of ABPP with a preparation that has good availability are indicated to determine the potential antitumor activity of this agent or this class of agents in humans.

Seven patients with progressive ileal or caecal carcinoid tumors and liver metastases were treated with human recombinant alpha-interferon (IFN alfa-2b) at a dosage of 2-4 x 10(6) U daily or every other day subcutaneously. Six patients had symptoms of the carcinoid syndrome. No change of tumor size lasting 4 to 40+ months (median, 18 months) was noted in 6 patients, and 1 patient had hepatic tumor progression. A decrease in urinary excretion of 5-hydroxyindoleacetic acid by more than 50% lasting 2-11 months (median, 4) was observed in 5 patients. Four patients were completely or partially relieved of flushing, diarrhea, obstruction or abdominal pain. The side-effects were negligible with the exception of mild fever, headache and confusion only during the first days of therapy. Treatment with IFN alfa-2b offers good palliation to patients with disseminated ileal or caecal carcinoid tumor and carcinoid syndrome.

Fourteen patients with epithelial ovarian cancer were treated with intraperitoneal (i.p.) administration of alpha-recombinant interferon (rIFN-alpha 2) after documentation of persistent disease at second-look laparotomy and combination chemotherapy. After therapy, 11 patients had a surgical re-evaluation which confirmed 4 complete responses (36%), 1 partial response (9%), and disease progression in 6 (55%). Five of 7 patients (71%) with minimal residual disease (MRD, i.e. less than 5 mm) had a surgically-documented response, whereas there was none in the 4 patients whose tumors were greater than or equal to 5 mm. Fever greater than or equal to 38 degrees C was seen in 58%, greater than or equal to 39.0 degrees C in 18%; nausea and vomiting in 37%, and abdominal pain in 22%. There was no consistent alteration in peripheral WBC's during treatment, while i.p. monocytes and lymphocytes showed a significant boost on day 1 after each dose of rIFN-alpha 2. Natural killer (NK) lymphocyte cytotoxicity was elevated in the i.p. cavity fluid obtained from most patients on day 1 after treatment, while blood NK values showed considerable variability. Pharmacokinetic studies showed i.p. levels of rIFN-alpha 2 were 30-1000 times blood levels. I.p. rIFN-alpha 2 may act by increasing concentrations of drug and augmenting regional host cells in patients with MRD ovarian cancer.

Fourteen patients with persistent epithelial ovarian cancer documented at second look laparotomy after combination chemotherapy were treated with 146 cycles of alpha-recombinant interferon (rIFN-alpha 2) administered i.p. The initial dose was 5 X 10(6) units which was escalated weekly to 50 X 10(6) units over 4 weeks and then continued weekly for a total of 16 weeks. Eleven patients underwent surgical reevaluation after therapy which confirmed four pathological complete responses (36%), one partial response (9%), and disease progression in six patients (55%). Five of seven patients (71%) with residual tumor less than 5 mm had a surgically documented response, whereas there was no response in the four patients whose tumors were greater than or equal to 5 mm. Three patients were evaluable for clinical response only: one patient who refused surgery had a complete clinical response with total resolution of ascites; one had stable disease; and one had disease progression. Fever greater than or equal to 38 degrees C was seen in 58%, fever greater than or equal to 39.0 degrees C was seen in 18%, vomiting in 37%, abdominal pain was reported in 22%, and one patient had infectious peritonitis. Peripheral white blood cell counts and i.p. washings were obtained pretreatment and on days 1, 3, and 7 after treatment. While there was no consistent alteration in peripheral white blood cell counts, the numbers of i.p. monocytes and lymphocytes showed a significant boost on day 1 after each dose of rIFN-alpha 2. Natural killer lymphocyte cytotoxicity was elevated in the i.p. cavity fluid obtained from most patients on day 1 after treatment, while blood natural killer lymphocyte cytotoxicity values showed considerable variability. Pharmacokinetic studies show that i.p. levels of rIFN-alpha 2 were 30-1000 times blood levels. rIFN-alpha 2 i.p. may act by increasing concentrations of drug and augmenting regional host cells in patients with minimal residual ovarian cancer.
