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.

We reviewed the records of 1,323 patients with retinoblastoma treated here between 1922 and 1978. Twenty-eight patients underwent bilateral enucleation alone and received no additional treatment for their advanced tumors. Of the 28 patients, 22 (92%) survived. Four patients were lost to follow-up, and two died of metastatic retinoblastoma. Of 22 survivors of bilateral retinoblastoma treated with enucleation alone, three developed second tumors at a mean of 15.3 years after bilateral enucleation. One patient developed a rhabdomyosarcoma in the left temple region, the second patient developed an osteogenic sarcoma of the right femur, and the third developed a malignant melanoma of the left thigh. All three patients died of their disease. The incidence of second tumors in patients who survived bilateral retinoblastoma treated without radiation was 14% (three patients), which is comparable to a series previously reported in which patients were treated with enucleation and irradiation.

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.

With modern techniques it is usually possible to deliver a high dose of radiation to an orbital tumour without destroying vision. Local cure of lymphoma is possible with no risk of complications. Rhabdomyosarcoma now has a very good prognosis if treated energetically by radiotherapy and chemotherapy. Radiotherapy also has a part to play in the management of lacrimal gland tumours, melanoma, and metastases. A recent series of cases provides evidence that radiotherapy may be the best treatment for some cases of pseudotumour.

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.

Rhabdomyosarcomas are malignant tumors, and especially occur in childhood. In adults they are extremely rare. A pleomorphe rhabdomyosarcoma of the skin, localized on the nose of an 85-year old female patient, is reported. After surgical removal the defect was reconstructed with a full skin graft. The four histologic types of rhabdomyosarcoma (pleomorphic, alveolair, embryonal, botryoid) are discussed.

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.
