Combination chemotherapy with adriamycin and DTIC was used in 102 evaluable patients under 15 years of age who had previously treated metastatic solid tumors. Responses, defined as 50% or more reduction in all tumor masses, occurred in 10 out of 27 patients with neuroblastoma, 3 out of 8 patients with Wilms tumor, 7 out 15 patients with Ewing sarcoma, 2 out of 6 patients with osteosarcoma, 5 out of 13 patients with rhabdomyosarcoma, and 15 out of 33 patients with miscellaneous tumors which included a patient who had a complete regression of an extensive juvenile angiofibroma. Response rate to combination chemotherapy with adriamycin and DTIC in patients with Ewing sarcoma was significantly superior to the response rate obtained with adriamycin alone in another Southwest Oncology Group Study. Major toxicity included nausea, vomiting, myelosuppression, high incidence of pneumocystis carinii pneumonia (5 patients) and congestive heart failure (4 patients). There was 7 drug-associated deaths due to sepsis (1), pneumocystis carinii pneumonia (4), and congestive heart failure (2).

The authors describe the results of five pediatric patients with nonmetastatic osteosarcoma of an extremity, admitted from 1987 to 1989 to the Hospital Infantil del Estado de Sonora. Four patients presented with their primary tumor located at the distal end of the femur, whereas one had a primary lesion of the humerus. All of them received preoperative chemotherapy consisted of two cycles of cisplatin and adriamycin. One of the patients presented immediate complications after first cicle and died due to overwhelming sepsis by Candida albicans. Surgery was an amputation in one patients and block ressection in three cases. Necrosis was good in three cases, fair in one. Postoperative chemotherapy consisted of bleomycin, cyclophosphamide and dactinomycin every four weeks alternated with cisplatin plus adriamycin. One of the three patients, in which block ressection was made, had a local recurrence 12 months after diagnosis, without metastasis. He underwent desarticulation and died four months later of leukoencephalopathy and no tumor was found on necropsy. Three patients have remained continuously free of disease with follow up of 20, 26 and 31 months after diagnosis and are out of chemotherapy since 5, 12 and 17 months, respectively. In two of them the affected extremity still is safe.

The peripelvic area consists of the bony pelvis, hip joints and adjacent mesenchymal soft tissues. Malignant lesions in this area present unique diagnostic and therapeutic problems, in particular when tumor removal is involved. Between 1986 and 1988 we treated 7 females and a male, aged 8-75 years, for malignant tumors of this area. Diagnoses (histologic) included 4 cases of malignant fibrous histiocytoma, a malignant schwannoma, a Ewing sarcoma, a chondrosarcoma, and an osteosarcoma. Operations included marginal resection (4 cases), radical resection and reconstruction (2), radical resection (1), and modified hemipelvectomy (2). Adjuvant therapy consisted of radiotherapy in 1 case, chemotherapy in 2, and a combination of both in another 2. A patient who underwent radical resection and reconstruction of his left hemipelvis and hip joint died of local infection that progressed to generalized sepsis 2 months after operation. 2 patients died of recurrent disease, 3 and 30 months, respectively, after primary therapy. 1 died of myocardial infarction 20 months after the first and 3 months after the last of a series of marginal resections. 3 patients are alive and well 3-24 months following their first operation, and the fourth is doing well 24 months following first operation and 23 months after resection of lung metastases. Soft tissue sarcomas and osteosarcomas are the most frequent malignant tumors encountered in the pelvis and peripelvic areas. Their varying grades of malignancy and metastatic potential influence the approach on the one hand, while invalidity and compromised quality of life associated with tumor resection, influence it on the other.(ABSTRACT TRUNCATED AT 250 WORDS)

Postoperative course is reported in 52 children with malignant tumors (neuroblastoma, Wilms-tumor, non-Hodgkin-lymphoma, osteosarcoma etc.) who were operated on between 1979 and 1987. 26 children received chemotherapy prior to surgery, whereas 26 children were operated on without preceding chemotherapy (control group). Most children were under six years of age. 15 Children (57.7%) with preoperative chemotherapy developed early postoperative complications, such as sepsis, pneumonia, suture dehiscence, woundhealing disturbances and ileus, whereas this was the case in only 5 children (19.2%) without preoperative chemotherapy (P 0.0005). Four of the children with preoperative chemotherapy (15.4%) sustained late complications, such as local recurrence or mechanical bowel obstruction, whereas none of the control children did so. Lethality rate from underlying disease did not differ in both groups during follow-up (5 = 19.2% vs. 5 = 19.2%). This demonstrates that the surgeon must carefully be aware of an increased possibility of early and late complications in children who have to undergo surgery for malignant tumors following preoperative chemotherapy.

One hundred twenty-four children and young adults with recurrent tumors, predominantly sarcomas, were treated with the combination of ifosfamide, etoposide, and the uroprotector, mesna (2-mercaptoethane sulphonate), in a phase II trial. The treatment regimen consisted of 12 cycles of therapy administered every 3 weeks. After evaluation of the tumor response to chemotherapy alone, radiation or surgery was used to eradicate residual sites of metastatic disease where possible. At the present time, 77 patients are evaluable for response to the chemotherapy; 43 of the patients have experienced a significant reduction in the tumor size in response to the chemotherapy alone (39 partial responses [PR] and four complete responses [CR]). Sixteen of 17 patients with Ewing's sarcoma, nine of 13 with rhabdomyosarcoma, four of eight with peripheral neuroepithelioma, three of eight with osteosarcoma, and 11 of 31 with other tumors have responded with a PR or CR. The toxicity of the regimen was acceptable. Moderate or severe toxicity evaluated on a per cycle basis included: neutropenia, 97%; thrombocytopenia, 32%; nephrotoxicity, less than 1%; mucositis, 1%; neurologic toxicity, 2%; nausea and vomiting, 13%; hemorrhagic cystitis, less than 1%. Fever was present after 33% of cycles and sepsis following 7%. One patient died due to sepsis and pancytopenia. At the present time, only seven of the 43 patients who responded to the chemotherapy regimen have relapsed, with a median follow-up of 10 weeks after the response. This drug combination is highly active in the treatment of recurrent sarcomas and other tumors in children and young adults.

The clinical and microbiologic characteristics of 29 episodes of sepsis caused by Acinetobacter calcoaceticus were reviewed in 25 children with underlying malignancies. Of the 29 episodes of sepsis with this organism 28 occurred from 1980 through 1984, compared with 1 episode from 1973 to 1979. Risk of infection was associated with the presence of intravascular cannulae, osteosarcoma and recent administration of antitumor chemotherapy. There was no association with neutropenia, malnutrition or focal infection. Of 28 organisms for which the biotypes were known, 14 (50%) were var. lwoffi and 14 (50%) were var. anitratus; 11 episodes (38%) were part of a polymicrobial bacteremia. All patients responded favorably to antimicrobial therapy.

Current therapy for children with cancer includes a variety of invasive procedures many of which require repeated venous access over a considerable period of time. Such procedures are poorly tolerated by children and by their veins. Recently it has become possible to undertake the majority of such procedures by means of permanent indwelling silastic catheters improving the quality of life of the children and their parents and increasing the scope of therapeutic intervention. In the period July '83 - August '84 we have used 46 of these catheters in 45 children with malignant disease, 12 with acute myeloid leukaemia, 12 with neuroblastoma, 7 with B cell leukaemia-lymphoma, 6 with rhabdomyosarcomas, 2 with Ewing's Sarcoma, 2 with Wilms' tumor and 1 case each of Hodgkin's disease, teratocarcinoma, osteosarcoma and juvenile chronic myeloid leukaemia. The children's ages ranged from 2 months to 14 years; 22 were male and 23 female. The catheters were inserted under general anaesthesia (duration 20-40 minutes) usually without difficulty, except for a single patient in whom no suitable vein could be found. No complications connected with the placement of the catheter were observed. Subsequent management of the catheter was initially complicated and time-consuming, but was subsequently simplified so that acceptance by parents, children and nursing staff was eventually excellent. The duration of use of 46 catheters ranges from 7 to 350+ days; 24 catheters are presently in use at 30-350+ days from insertion. Eight children died as a result of disease progression and two of sepsis with the catheter in place.(ABSTRACT TRUNCATED AT 250 WORDS)

Diaziquone (AZQ), a new lipid-soluble antitumor agent, was given by 15-30-minute infusion on a daily X 5 schedule to 47 children with refractory solid tumors and leukemia. The starting daily dose of 6 mg/m2 was escalated to 10 and 35 mg/m2 in patients with solid tumors and leukemia, respectively. In patients with solid tumors, myelosuppression was dose-limiting at a daily dose of 10 mg/m2. In patients with leukemia, prolonged pancytopenia and bone marrow hypoplasia were observed at daily doses greater than or equal to 25 mg/m2. At these higher doses, significant hyperbilirubinemia associated with sepsis was also seen. Corresponding increases of transaminases or alkaline phosphatase and significant hemolysis were not noted. The maximum tolerated dose for this daily dose schedule was 9 mg/m2 in children with solid tumors and 25 mg/m2 in children with relapsed leukemia. Responses to AZQ included stabilization of disease in osteosarcoma, neurofibrosarcoma, pinealoma, and ependymoma. A patient with juvenile chronic myelocytic leukemia in blast crisis converted back to the chronic phase. A patient with acute lymphoblastic leukemia had a substantial decrease in cerebrospinal fluid blast count. Bone marrow aplasia was achieved in children with acute lymphoblastic leukemia and acute nonlymphoblastic leukemia; however, remissions were not achieved. A phase II study of AZQ in children with refractory malignancies is now being performed by the Childrens Cancer Study Group.

Chemokines contribute to the inflammatory response by selective attraction of various leukocytic cell types. Human GCP-2 was originally identified by amino acid sequence analysis as a CXC chemokine co-produced with IL-8 by osteosarcoma cells. Furthermore, the complete coding domain of human GCP-2 was disclosed by means of RT-PCR. Similarly, mouse GCP-2 was isolated from fibroblastoid and epithelial cells and completely identified by sequence analysis. Human and mouse GCP-2 share 61% identical amino acids. Both chemokines occur as multiple NH2-terminally truncated forms. The shorter forms of mouse, but not those of human, GCP-2 showed a higher neutrophil chemotactic potency and gelatinase B releasing capacity. Mouse GCP-2 was a more potent neutrophil activator than human GCP-2, natural mouse KC, and MIP-2. Human GCP-2 was not chemotactic for monocytes, lymphocytes, or eosinophils. Quantitative studies of mRNA expression in diploid fibroblasts revealed GCP-2 induction by IL-1beta. Human GCP-2 induced [Ca2+]i increase in neutrophils, which was reciprocally desensitized by IL-8, GROalpha, and ENA-78. Human GCP-2 induced [Ca2+]i increases and chemotactic responses in both CXCR1- and CXCR2-transfected cells. Finally, GCP-2 provoked neutrophil accumulation and plasma extravasation in rabbit skin. In humans, GCP-2 complements the activity of IL-8 as neutrophil chemoattractant and activator but it constitutes a major neutrophil chemokine in the mouse. GCP-2 induces neutrophil chemotaxis and activation but it might also contribute to detrimental tissue damage in sepsis, acute respiratory distress syndrome, acute hypersensitivity reactions, and autoimmune diseases. It might also influence the invasive capacity of GCP-2-secreting tumor cells.

The incidence of documented infections after autologous peripheral blood progenitor cells transplantation (PBPCT) was retrospectively evaluated in 86 consecutive patients (47 males 39 females; median age 36 years, range, 18-63) treated in our institution; 83 patients had refractory hematological malignancies (40 non-Hodgkin's lymphoma, 19 Hodgkin's disease, 17 multiple myeloma, 7 acute myeloblastic leukemia) and 3 had solid tumors (1 rabdomyosarcoma, 1 neuroblastoma, 1 osteosarcoma). All patients developed fever after transplantation lasting a median of 2 days (range 1-17); 20 instances of documented sepsis developed in 17 patients (19.7%). Gram positive microorganisms were implicated in all but 4 cases. There were no fatalities directly due to infections and no correlation was found between the risk of infection and reaching PMN > 0, 1 x 10(9)/L, PMN > 0.5 x 10(9)/L. In addition no specific risk factors related to age, disease, conditioning regimen, use of central venous catheter (CVC), type of transplant, and isolation measures were identified.
