As children with cancer survive longer, the incidence of second malignant neoplasms has increased considerably. We describe here three cases of second solid tumors after 12, 8 and 2 years of initial diagnosis of cancer: one
osteosarcoma
of left maxilla in a previously treated child with bilateral retinoblastoma, a temporal astrocytoma associated with acute lymphoblastic leukemia and a glioblastoma multiforme in a girl with neurofibromatosis de Von Recklinghausen, after Non
Hodgkin lymphoma
, respectively. We review the literature about the influence of genetic, immunologic and therapeutic factors involved in the appearance of these second tumors.

The scheduling of chemotherapeutic agents may be important in optimising their antitumour actions. This has been explored in non-
Hodgkin lymphoma
,
osteogenic sarcoma
and bladder cancer with improved results using intensive, weekly dosing schemas. We began a phase II study of cisplatin, 5-fluorouracil and vinblastine in non-small cell lung cancer (NSCLC) on a weekly schedule. 38 patients with advanced or metastatic NSCLC were entered; 32 are evaluable for response. 11 patients were treated with 5-fluorouracil 1.5 g/m2 and vinblastine 4 mg/m2 by 24-h continuous infusion, and cisplatin 30 mg/m2 over 30 min, 6-8 h after the start of the infusion. Because of prohibitive myelotoxicity, the next 27 patients received 5-fluorouracil 1.2 g/m2 and vinblastine 3 mg/m2. None had had prior chemotherapy while 6 had had previous radiation therapy. Myelosuppression was the predominant toxic effect. Other side-effects included neuropathy, diarrhoea, mucositis, nausea and vomiting. 32 patients are evaluable for response: there have been 14 partial remissions (44%). Responses have occurred chiefly in lung and lymph nodes. The median survival on this study is 7 months, and responders did not live longer than non-responders. While this regimen is well tolerated by the majority of patients and has a response rate comparable to other active regimens identified in single institution studies, survival does not appear to be enhanced. We conclude that the schedule manipulation described here does not enhance the therapeutic index of these drugs in NSCLC.

The production and detailed immunostaining properties of a new rat monoclonal antibody (ICR.2) to epithelial membrane antigen are reported. The antibody was selected for its ability to compete with the polyclonal antiserum (M7), used in the original immunohistological studies, in order that it might serve as a direct replacement in diagnosing epithelial tumours. Most of the staining reactions on normal tissues were identical to those previously reported with M7 but there were some important differences. They included: positivity of renal and adrenal capsular fibroblasts, perineurium, some myoepithelial and smooth muscle cells, occasional osteoblasts and squamous and thyroid follicular epithelium in the normal state. The intercellular canaliculi of sweat glands and secretory canaliculi of gastric oxyntic cells were clearly demonstrated. These staining reactions could be obtained with M7 when a sensitive detection system was used although the results were usually weak and inconsistent. Nearly all adenosquamous and transitional carcinomas were positive. The remaining tumours fell into three major groups: (1) those which were consistently or nearly consistently negative--melanoma, seminoma, rhabdomyosarcoma, alveolar soft part sarcoma, adrenal cortical carcinoma, granulocytic sarcoma, paraganglioma, non-Hodgkin's lymphoma.
Hodgkin's disease
and embryonal carcinoma: (2) those which were either negative or positive with distinctive patterns of staining--basal cell carcinoma, embryonal tumours: and (3) non-epithelial tumours that were consistently positive--epithelioid sarcoma, synovial sarcoma,
osteosarcoma
, chordoma and myeloma--or positive in a significant minority of cases--leiomyosarcoma, malignant fibrous histiocytoma, clear cell sarcoma of tendon sheath, various neuroectodermal tumours.(ABSTRACT TRUNCATED AT 250 WORDS)

The c-fos proto-oncogene, which is the normal homolog of the transforming gene carried by murine
osteogenic sarcoma
viruses, interacts with the protein product of another proto-oncogene, c-jun, to form a heterodimer that can recognize and bind to a specific sequence of nucleotides in the DNA. The expression of c-fos and c-jun is linked to the proliferation of certain cells and the differentiation of others, including those of monomyelocyte lineage. The authors used two cultured
Hodgkin
's Reed-Sternberg (H-RS) cell lines, KM-H2 and HDLM-1, and their single-cell clones to study the correlation of c-fos/c-jun expression with cell differentiation in H-RS cells. Within 48 hours after induction with phorbol ester (TPA), both parent lines exhibited markedly increased expression of c-fos/c-jun. The expression returned to the preinduction level after 96 hours, however, and the cells retained their differentiated status. The transitory increase in c-fos/c-jun expression suggests that binding of these proteins to a specific promoter in the nucleus triggers a cascade of events that result in cell differentiation. Expression of these proteins may not be required for the cells to maintain their differentiation. The authors selected three groups of sublines of HDLM-1 cells based on their degree of spontaneous cytologic differentiation. The first group, without obvious differentiation, showed a c-fos/c-jun expression pattern similar to that of the parent line. The second group, with moderate differentiation, had a high degree of expression, which decreased on treatment with TPA. The third group, which had morphologic features resembling those of histiocytes, expressed minimal amounts of c-fos/c-jun, irrespective of TPA treatment. These findings provide further evidence that c-fos/c-jun expression is related to differentiation of H-RS cells, and that these proteins are not byproducts of TPA induction. Expression of c-fos/c-jun also was noted in a subpopulation of H-RS cells in tissues; and this expression also was enhanced when these cells were treated with TPA in culture. These findings indicate that H-RS cells can differentiate to become mature-appearing cells in tissues.

High-dose thiotepa was given as a single agent at a total dose of 1125 mg/m2 with autologous bone marrow rescue to nine patients with recurrent/refractory/poor risk pediatric malignancies (primitive neuroepithelial tumor (PNET), two; neuroblastoma, one; Wilms' tumor, one;
osteosarcoma
, one; Ewing's sarcoma one,
Hodgkin's disease
one, high-grade glioma, two). The response rate in these heavily pretreated patients was 71% (five out of seven evaluable patients) including two complete responses (Wilms', glioma), three partial responses (
osteosarcoma
, Ewing's sarcoma,
Hodgkin's disease
), and two with stable disease (PNET, glioma). The median duration of response was 2.5 months. The extramedullary toxicity was acceptable with symptoms mainly of skin and gastrointestinal tract. The data indicate that high-dose thiotepa is effective in several types of recurrent pediatric solid tumors, and merits further evaluation in combination regimens.

The Pediatric Oncology Group compared two regimens that employed involved field radiotherapy 3,500 rad and either MOPP + Bleo or A-COPP chemotherapy, given in a sandwich fashion, as treatments for stage III Hodgkin's disease in children under the age of 18 years. Eighty-four surgically staged children from the United States and Mexico who had been randomly assigned to treatment during the period from July 1976 through October 1982 were evaluated. Unfavorable disease characteristics were distributed equally between the treatment groups. The percentages of children achieving complete remission by regimen were 84% for MOPP + Bleo and 92% for A-COPP. For those continuing in complete remission, the percentages were 71% for MOPP + Bleo and 72% for A-COPP. For those surviving 9 years, the percentage was 84% for MOPP + Bleo and 85% for A-COPP. The presence of low abdominal disease at diagnosis did not adversely influence response to therapy or survival. All deaths among MOPP + Bleo cases occurred within 4 years of study entry; 3 late deaths in A-COPP cases at 8-10 years were due to
osteosarcoma
, cardiopathy, and recurrent
Hodgkin's disease
. The preferred treatment regimen for future use cannot be determined until the cardiotoxicity of Adriamycin is eliminated by the development of drug delivery techniques that reduce cardiotoxicity or anthracycline congeners that are not cardiotoxic.

A total of 2259 children with solid malignant tumors were treated at St. Jude Children's Research Hospital between the years 1962 and 1987. Of these, 112 (5%) developed spinal epidural metastasis with spinal cord compression during the course of their disease process. Metastatic epidural spinal cord compression was caused most commonly by Ewing's sarcoma and neuroblastoma, followed by
osteogenic sarcoma
, rhabdomyosarcoma,
Hodgkin's disease
, soft-tissue sarcoma, germ-cell tumor, Wilm's tumor, and (rarely) hepatoma. There was no significant difference in outcome between patients with small-cell tumors (neuroblastoma,
Hodgkin's disease
, and germ-cell tumors) who received only chemotherapy and/or radiation therapy and the patients with similar lesions who received a decompressive laminectomy alone or prior to chemotherapy and/or radiation therapy. Patients with spinal cord compression from metastatic sarcoma (Ewing's sarcoma, soft-tissue
sarcoma, osteogenic
sarcoma, and rhabdomyosarcoma) showed a significant improvement with decompressive laminectomy alone or before medical therapy, compared to those who received radiation therapy and/or chemotherapy without posterior decompression. Pediatric tumors invade the spinal canal via the neural foramen, compressing the spinal cord in a circumferential manner, allowing decompressive laminectomy (posterior approach) to be an effective surgical approach. Sixty-six percent of children who had no evidence of motor or sensory function below the level of the compression became ambulatory after surgical decompression and medical treatment, regardless of tumor type.

Lag time (the interval between symptom onset and diagnosis) was described for 2665 children with lymphoma or a solid tumor who participated in Pediatric Oncology Group therapeutic protocols from 1982 until 1988. Median lag time ranged from 21 days for neuroblastoma to 72 days for Ewing sarcoma. Significant differences in lag time were found among diagnostic groups (p less than 0.001), even after adjustment for age, gender, and race. Age was significantly associated with lag time for all diagnoses (p less than 0.05) except
Hodgkin disease
. Girls had increased lag times for non-
Hodgkin lymphoma
(p = 0.02) but decreased lag times for Ewing sarcoma (p = 0.02). Differences in lag time related to race were significant only for children with
osteosarcoma
(p = 0.02), for which white children had longer lag times. Type of tumor and age were strongly associated with lag time. Within diagnostic groups, age, gender, and race failed to explain more than 16% of the variance in lag time, suggesting that other factors may play more prominent roles. Further study is necessary to identify these factors and to assess the relationship between lag time, stage of disease at diagnosis, and prognosis, especially before designing early-detection interventions for childhood cancer.

Between 1965 and 1988, at the Children's Hospital of Buenos Aires, 22 children developed two successive malignant tumors of different histology. The first tumor was diagnosed between 3 months and 12 years of age: 13 retinoblastoma, 2 rhabdomyosarcoma, 2 non-
Hodgkin lymphoma
, 2
Hodgkin disease
, 1 brain stem glioma, 1 endodermal sinus tumor and 1 Ewing sarcoma. Familial cancer was registered in 6 patients. Children were treated with surgery, intensive chemo and radiotherapy. The second malignancy developed after 2 to 13 years: 10
osteosarcoma
, 2 Ewing sarcoma, 2 rhabdomyosarcoma, 2 glioblastoma, 1 medulloblastoma, 1 synoviosarcoma, 1 fibrosarcoma, 1 thyroid carcinoma, 1 acute lymphoblastic leukemia and 1 acute myeloblastic leukemia. In 17 patients, the tumor developed in irradiated field. There was no evidence of the first tumor and only 1 patient was still under chemotherapy. Oncologic treatment was frustrating for these second tumors and 18 children died. Three are alive with no evidence of disease at 2 years, 2 years and 4 months and 3 years after diagnosis. One patient was lost to follow-up. It if postulated that second malignant tumors are consecutive to genetic predisposition and/or to the oncogenic effect of chemo and radiotherapy. The intensity of each treatment modality must be reduced as much as possible to obtain survival while limiting the secondary effects.

We studied the efficacy of mesna as a protectant for urotoxicity in pediatric patients receiving chemotherapy including oxazaphosphorines. Nineteen patients with malignant diseases (5 neuroblastoma, 3 acute lymphocytic leukemia, 4 acute non-lymphocytic leukemia, 2 non-
Hodgkin lymphoma
, 3
osteosarcoma
and 2 rhabdomyosarcoma) were treated with a total of 106 courses of therapy between June of 1986 and May of 1989. Of these, no gross hematuria were seen. Microhematuria transiently occurred only in 2 courses (5%) of 1 patient (2%). These data indicated that mesna was highly effective for urotoxicity of oxazaphosphorines without any side effects, especially in pediatric patients.
