Children with malignancies resistant to conventional therapy were treated with cis-diamminedichloroplatinum (PDD), 15 to 20 mg/m2, given daily by rapid intravenous infusion for 5 days at 3-wk intervals. Eleven of 24 children with acute lymphocytic leukemia (ALL) received two or more courses; among these no remissions occurred. Fifty-four children with solid tumors were treated: 25 neuroblastoma, 9 rhabdomyosarcoma, 4 Ewing sarcoma, 2 testicular embryonal carcinoma, 2 retinoblastoma, and 12 miscellaneous tumors. One complete remission, 3 partial remissions, and 2 improvements were observed in children with neuroblastoma. One girl with metastatic osteogenic sarcoma achieved a partial remission. One child with metastatic testicular embryonal carcinoma showed improvement. The side effects were vomiting controlled by antiemetics in 26 children and transient elevations of serum creatinine and BUN in 14 children. Nineteen of 39 children with solid tumors, who received more than one course of PDD, had moderately severe myelosuppression caused by PDD. In summary, PDD is a promising agent in neuroblastoma, osteogenic sarcoma, and testicular embryonal carcinoma, and an ineffective agent in ALL. The effect of PDD on other types of solid tumors should be evaluated in the future.

The latency period, success rate, and minimal cell inoculum size required for transplantation of continuously passaged human tumor lines into congenitally athymic (nude) mice, antilymphocyte serum (ALS)-treated congenitally athymic (nude) mice, and congenitally athymic-asplenic (lasat) mice were compared. The 11 tumor lines studied included examples of breast adenocarcinoma, transitional cell carcinoma, osteosarcoma, fibrosarcoma, Hodgkin's disease, malignant melanoma, and rhabdomyosarcoma. Of these 11 tumor lines, 3 were successfully transplanted into nude mice, compared to 5 of 10 tumor lines in ALS-treated nude mice and 9 of 11 lines in lasat mice. Moreover, the latency period was shorter and the minimal cell inoculum size was lower for lasat mice than for either nude or ALS-treated nude mice. Despite this enhancement of heterotransplantation into lasat mice and despite the growth of large local masses, no evidence of distant metastases was found.

A combination of the radiosensitizer, metronidazole, and the radioprotector, dimethyl sulfoxide (DMSO), was tested for its effects on the radiation tolerance of rat skin and on the radiosensitivity of the BA1112 rhabdomyosarcoma. The simplest interpretation of the effects of the combined treatment is that: metronidazole radiosensitizes BA1112 in one-fraction but not in five-fraction treatments; metronidazole slightly increases the radiosensitivity of skin in one-fraction treatments; metronidazole radiosensitization is independent of the radioprotection produced by DMSO.

Radium therapy at the age of 3 years for an embryonic rhabdomyosarcoma of the paranasal fold resulted in severe cutaneous lesions but also relatively limited disturbances of growth of the corresponding maxilla: inclusion of the underlying canine and version of neighbouring teeth, very incomplete development of the nearest dental roots, absence of air filling of the maxillary sinus. The relatively slight nature of these developmental disturbances is certainly related to the techniques of interstitial radium therapy developed and used at the Gustave Roussy Institute. Routine orthodontic study of the cases of children surviving after treatment of a malignant tumor of the face would undoubtedly offer even more precise information concerning therapeutic indications.

VP-16-213, a semisynthetic podophyliotoxin, was tested for antitumor and clinical toxicity in 126 children. The drug was administered iv daily x 5 days every 2 weeks at a starting dose of 75 mg/m2/day. The dose was increased by 25 mg/m2/day/course until clinical response or significant toxicity occurred. The only major toxicity was hematologic, with neutropenia as the most predominant feature. There was one local allergic reaction at the site of injection. No systemic allergic responses were reported. The drug demonstrated significant activity in acute myelomonocytic leukemia with four responses among 19 patients, less activity in acute myelocytic leukemia with two responses among 44 patients, and little activity in acute lymphocytic leukemia with only one partial response among 12 patients. Objective partial responses occurred in ten of 48 patients with solid tumors: two each with Wilms' tumor, lymphoma, and histiocytosis X, and one each with rhabdomyosarcoma, neuroblastoma, Ewing's sarcoma, and undifferentiated carcinoma. The inclusion of VP-16-213 in combination chemotherapy for childhood acute myelomonocytic leukemia and acute myelocytic leukemia appears indicated in patients relapsing after initial therapy. For solid tumors this is an interim report, with further patient accrual required before specific comments can be made.

Eleven cases of Pneumocystis carinii pneumonia were diagnosed during a 3 1/2-year period at a pediatric hospital where this infection had never been identified previously despite appropriate studies. The incidence of infection was 3.0, 7.4, and 4.2 cases per 1,000 patient months in children being treated for acute leukemia, neuroblastoma, and rhabdomyosarcoma, respectively. The outbreak coincided with increased intensity of chemotherapy for these malignancies. Ten of the patients had received four or more chemotherapeutic agents within three months of the onset of infection. Because no exogenous source of the epidemic was found, latent endogenous infection activated by immunosuppression was presumed to be the ultimate cause of the outbreak. Increased intensity of chemotherapy may result in P carinii outbreaks and may be an indication for anti-Pneumocystis prophylaxis with trimethoprim/sulfamethoxazole in patients at risk.

Rhabdomyosarcoma of the head and neck may be treated with surgery, radiotherapy and chemotherapy or a combination thereof. Precise delineation of the full extent of the tumor in the head and neck is essential. Routine radiographs with hypocycloidal tomography and CT are complementary in defining the full extent of the lesion. Tomography is superior to CT scanning in demonstrating fine bone detail. Demonstration of the soft tissue tumor and its extensions is better seen on CT. The ability to discriminate differences more accurately in densities allows computerized tomography to appreciate better the integrity of the bone margins such as the thin walls of the sinuses.

The paratesticular region was the primary site in 20 of 289 children (7%) entered on the Intergroup Rhabdomyosarcoma Study. The 20 patients were 1.7- to 19-years-old at diagnosis. Fifteen underwent retroperitoneal node dissection (12) or biopsy (3), and 6/15 (40%) had nodal involvement by tumor. Nineteen of the 20 patients had no gross local or metastatic disease after surgery. All 20 received chemotherapy, and 13 also received radiotherapy. Treatment was effective: 16 of 18 evaluable patients (89%) were free of disease at a median of 23 months from diagnosis (range, 8-43 months). Since the incidence of tumor-involved retroperitoneal nodes is high, a dissection should be performed. If the nodes are free of tumor, retroperitoneal radiotherapy may not be necessary. Reduction of morbidity in patients with paratesticular rhabdomyosarcoma is desirable, because the disease has a good prognosis.

Twenty-seven previously untreated children with gross residual (20) or metastatic (seven) rhabdomyosarcoma were treated with pulse-VAC (vincristine weekly for 12 doses plus dactinomycin and cyclophosphamide simultaneously given daily for 5 days) and radiotherapy. Toxicity during the 12-week induction period included 23 of 27 (85%) with an absolute neutrophil count (ANC) under 500/mm3; 16/27 (59%) were given intravenous (I.V.) antibodies. Three patients developed Gram-negative sepsis and two of them died. In the first 12 weeks, eight children had a complete response (CR) and another 10 a good partial response (PR), a total of 18 of 27 favorable responses (67%). At 12 weeks, 20 patients received either intermittent pulse-VAC (Regimen H) or a pulse of adriamycin plus vincristine and cyclophosphamide alternating with pulse-VAC (Regimen I) every 4--6 weeks. After this first "maintenance," only seven patients (35%) developed an ANC under 500/mm3 and only three (15%) were given I.V. antibiotics. Severe toxicity disappeared with drug dose reduction in subsequent courses. The overall CR rate was 59% with a PR rate of 15%, a total of 74% favorable responses. This rate is not significantly better than that obtained by previous IRS chemotherapy and radiotherapy schedules for patients with gross residual and metastatic rhabdomyosarcoma. Future studies in these patients will concentrate on diminishing myelosuppression while shortening the rest period between pulses, in order to deliver more drug per unit time.

Preliminary clinical trials using cryopreserved autologous bone marrow reinfusion have now been carried out at our institution in 5 children and 2 adults with advanced stages of neuroblastoma, rhabdomyosarcoma, non-Hodgkin's lymphoma and small cell carcinoma of the lung. Normal numbers of in vitro colony forming cells (CFU-C) were obtained from these patients despite prior courses of combination chemotherapy. The dose of marrow cells cryopreserved ranged from 1-6 X 10(8) cells/kg and recovery of CFU-C after thawing averaged 50%. Partial or complete hematologic reconstitution was achieved in all patients. The time for recovery ranged from 10-43 days for leukocytes (greater than 1000 cells/mm3) and 23-45 days for platelets (greater than 50,000/mm3). Two patients have died of interstitial pneumonitis due to cytomegalovirus. Three patients have died of recurrent tumor at 40, 48 and 156 days post-transplant. Two patients have had significant therapeutic benefit. One of these had a stable partial response permitting the use of further post-transplant therapy and is alive and well 16+ months post-transplant. The other patient had a complete response and remains tumor-free 25+ months following therapy. We conclude: 1) Autologous bone marrow reinfusion permits hematologic reconstitution following marrow-ablative therapy. 2) A quantity of marrow sufficient for this purpose remains viable following cryopreservation even when obtained from patients previously exposed to chemotherapy. 3) Autologous bone marrow reinfusion now allows the exploration of more intensive cytoreductive therapy in selected malignancies.
