Abstract
OBJECTIVE To catalog and evaluate patterns of disease in families of children with pleuropulmonary blastoma (PPB). METHODS Data have been collected since 1988 on 45 children with PPB and their families. All pathologic materials were centrally reviewed. Preliminary molecular genetic analyses were performed when possible. RESULTS In 12 of 45 patients, an association was found between PPB and other dysplasias, neoplasias, or malignancies in the patients with or in their young relatives. The diseases found to be associated with PPB include other cases of PPB, pulmonary cysts, cystic nephromas, sarcomas, medulloblastomas, thyroid dysplasias and neoplasias, malignant germ cell tumors, Hodgkin disease, leukemia, and Langerhans cell histiocytosis. Abnormalities of the p53 tumor suppressor gene, Wilms tumor suppressor gene (WT1), and the putative second genetic locus for Wilms tumor (WT2) were not found in preliminary investigations. CONCLUSIONS The occurrence of PPB appears to herald a constitutional and heritable predisposition to dysplastic or neoplastic disease in approximately 25% of cases. All patients with PPB and their families should be investigated carefully. Further research of this new family cancer syndrome may provide insight into the genetic basis of these diseases.

Abstract
The organization of the collagen fibrils in the human umbilical cord at term is directly visualized by means of a scanning electron microscopy cell maceration method. This technique clearly reveals that there is a much more extensive collagen fibrillar architecture within the umbilical cord than that reported in the classical histological descriptions. The Wharton's jelly, in fact, appears as a spongy network of interlacing collagen fibres and small woven bundles apparently arranged at random and forming a continuous soft skeleton that encases the umbilical vessels. The collagen fibrillar network shows the presence of a wide system of interconnected cavities consisting of canalicular-like structures as well as cavernous and perivascular spaces. This system of cavities might play a mechanical role allowing the storing of the ground substance of the jelly and its diffusion during twisting or compression. Furthermore, it may have an important role facilitating the diffusion throughout the jelly of diffused materials (i.e. water and trophic metabolites) either from or to the umbilical vessels and the amniotic cavity, thus overcoming the lace of a proper vasculature with the jelly.

Abstract
PURPOSE The ultimate goal of the Third Intergroup Rhabdomyosarcoma Study (IRS-III, 1984 to 1991) was to improve treatment outcome in children with rhabdomyosarcoma through clinical trials comparing risk-based protocols of surgery and multiagent chemotherapy, with or without irradiation. PATIENTS AND METHODS One thousand sixty-two previously untreated, eligible patients who were entered onto the study after surgery were randomized or assigned to treatment by clinical group (I through IV), histology (unfavorable or favorable), and site of the primary tumor. Initial responses, progression-free survival (PFS), and survival (S) were the end points used in comparisons between randomized groups and between patients treated in IRS-III and IRS-II (1978 to 1984). RESULTS The overall outcome of therapy in IRS-III was significantly better than in IRS-II (5-year PFS, 65% +/- 2% v 55% +/- 2%; P < .001 by stratified testing). Patients with group I favorable-histology tumors fared as well on a 1-year regimen of vincristine and dactinomycin (VA), as did a comparable group treated with VA plus cyclophosphamide (C) (5-year PFS, 83% +/- 3% v 76% +/- 4%; P = .18). Results for patients with group II favorable-histology tumors, excluding orbit, head, and paratesticular sites, were inconclusive regarding the benefit from addition of doxorubicin (ADR) to VA. Patients with group III tumors, excluding those in special pelvic, orbit, and other selected nonparameningeal head sites, fared much better on the more intensive regimens of IRS-III than on pulsed VAC or VAC-VADRC in IRS-II (5-year PFS estimates, 62% +/- 3% v 52% +/- 3%; P < .01); however, there were no significant differences in outcome among the groups treated in IRS-III. Patients with metastatic disease at diagnosis (clinical group IV) did not benefit significantly from the more complex therapies evaluated in IRS-III. CONCLUSION Intensification of therapy for most patients in IRS-III, using a risk-based study design, significantly improved treatment outcome overall. The largest gain from this strategy was realized in patients with gross residual tumor after biopsy (clinical group III). It was also possible to decrease therapy for selected patient subsets without compromising survival.

Abstract
The early occurrence of five cases of acute myeloid leukemia (AML) in children treated for primary rhabdomyosarcoma on the Intergroup Rhabdomyosarcoma Study III (IRS III) has prompted this report. These patients received cyclophosphamide and four received etoposide in addition to other agents. There were 1,062 eligible patients entered on IRS III between 1984 and 1991. Following surgery, treatment consisted of multiagent chemotherapy and radiotherapy in select clinical groups. Median follow-up time is 3.7 years (range 0-7.4 years). Incidence densities and odds ratios for AML were calculated for various treatment groups. Five cases of secondary AML have been reported through August 1992. A single case of osteogenic sarcoma was reported in the same period and a patient with myelodysplastic syndrome has occurred since that time. Median time to development of AML was 39 months. Incidence density of AML for patients receiving neither cyclophosphamide nor etoposide was 0, for those receiving cyclophosphamide but no etoposide it was 7.6, and when both agents were given, it was 51.6. The odds ratios of AML for the latter two groups indicated a risk of AML which was seven times higher in the patients who received both agents. A history of breast cancer was present in all five families of patients with AML and several other cancers had occurred in three families. Preliminary analysis suggests a possible causal role for low-dose etoposide in addition to that assumed for cyclophosphamide in the early development of AML among pediatric patients treated for rhabdomyosarcoma.

Abstract
BACKGROUND Recent reports have documented the occurrence of treatment-related acute myeloid leukemia (AML) following therapy with epipodophyllotoxins. These reports have led to growing concern among oncologists, which could lead to premature abandonment of these agents at a time when the relationship between cumulative dose of epipodophyllotoxin and risk of treatment-related AML has not been determined. PURPOSE Because of the increasingly important role of epipodophyllotoxins in the treatment of several types of adult and pediatric tumors, the Cancer Therapy Evaluation Program (CTEP) of the National Cancer Institute (NCI) has developed a monitoring plan to obtain reliable estimates of the risk of treatment-related AML following epipodophyllotoxin treatment. METHODS We identified 12 NCI-supported Cooperative Group clinical trials in which patients with solid tumors are being treated with epipodophyllotoxins at different cumulative doses. One trial is using a moderate dose of teniposide (900 mg/m2), and 11 trials are using etoposide at a low dose (< 1500 mg/m2), a moderate dose (1500-3999 mg/m2), or a high dose (> or = 4000 mg/m2). Cases of treatment-related AML and treatment-related myelodysplastic syndrome (MDS) (hereafter referred to as treatment-related AML/MDS) occurring in these trials are reported to CTEP, with initial analysis for each cumulative dose group triggered by the reporting of four cases of treatment-related AML/MDS in that group. For each analysis, total patient follow-up for the group is determined and cumulative 6-year incidence rate is calculated. RESULTS Three cases of treatment-related AML and one case of treatment-related MDS (with documented monosomy 7) were reported in a group of 207 patients who received etoposide at a low cumulative dose. The calculated 6-year rate of development of treatment-related AML/MDS was 3.2% (95% upper confidence interval bounded by 7.2%). CONCLUSIONS The 6-year cumulative rate of treatment-related AML/MDS (3.2%) is within the range previously reported for alkylator-based regimens that did not include epipodophyllotoxins. IMPLICATIONS Previous reports have suggested that higher cumulative doses of alkylators are associated with increased risk of treatment-related AML, and a critical goal of the monitoring plan is to determine whether a similar relationship exists for the epipodophyllotoxins. Estimates will be developed for leukemogenic risk for the moderate- and high-cumulative-dose groups when four cases of treatment-related AML/MDS have been identified within each group.

Abstract
BACKGROUND As increasing numbers of young patients with cancer survive, interest in the late effects of therapy is rising. METHODS The sequelae of treatment were reviewed after a minimum of 5 years of observation in 109 surviving patients with sarcoma of the bladder or prostate who were enrolled in the Intergroup Rhabdomyosarcoma Studies I and II (1972-1984). The 82 male and 27 female patients were 3 weeks to 19 years of age when the diagnosis was made (median, 2 years) and were 5-29 years of age at last contact (median, 11 years). Treatment consisted of chemotherapy with vincristine, dactinomycin, and cyclophosphamide and bladder irradiation in nearly all patients. RESULTS Fifty-four patients underwent total cystectomy, and 10 had a partial cystectomy. Of the 55 patients with bladder preservation, 1 had a urinary conduit with a nonfunctioning bladder. Thus, 54 bladders (50% of the total) remained in place as part of the urinary tract. There was no information regarding bladder function in two patients. Satisfactory bladder function was found in 38 patients (73%), 9 were incontinent, and 5 had urinary frequency with or without nocturia. Posttherapy hematuria was detected in 29% of patients. Nine of the 31 patients (29%) with follow-up renal imaging studies had a structural abnormality, chiefly hydronephrosis, which was more frequent in those with urinary diversion. Positive urine cultures were found mainly among those with enteric urinary conduits, but only two cases of pyelonephritis were documented. Abnormalities of irradiated bone and bowel were observed infrequently. Only one patient had a significantly elevated blood urea nitrogen or serum creatinine value, and only one patient was hypertensive. Most patients were still prepubertal at last follow-up. Of 24 patients who were intrapubertal or postpubertal, 7 (29%) were receiving sex hormone replacement because of delayed pubertal development. Height was decreased by 25% or more in 11 patients, as confirmed by growth chart analysis. Secondary surgical procedures other than repeat biopsy or cystectomy consisted primarily of urinary conduit revisions and repair of bowel adhesions or fistulous tracts. Information about psychosocial status was limited. CONCLUSIONS Overall, 50% of the patients retained their bladders, and 73% of them had satisfactory bladder function. Renal function was preserved in nearly every patient.

Abstract
PURPOSE This study was performed to determine the incidence and risk factors involved in the development of a second malignant neoplasm (SMN) after treatment of primary rhabdomyosarcoma (RMS) in patients enrolled onto Intergroup Rhabdomyosarcoma Studies I and II (IRS I and II). PATIENTS AND METHODS There were 1,770 patients with primary RMS entered onto IRS I and II between 1972 and 1984. They were treated with chemotherapy and, in most instances, radiotherapy according to randomized or assigned regimens based on clinical grouping. Median follow-up time for these patients was 8.4 years. Incidence density (ID) was calculated for each study and for treatment and age groups. The 10-year cumulative incidence was estimated for each study. RESULTS Twenty-two SMNs have been reported through 1991. The most common tumor type was a bone sarcoma followed by acute nonlymphoblastic leukemia (ANLL). The median time to the development of an SMN was 7 years (range, 1 11/12 to 15 9/12 years). The 10-year cumulative incidence rate was 1.7% for both studies. ID and cumulative incidence estimates were highest for patients who received both an alkylating agent and radiotherapy. The majority of patients for whom family histories were available had either neurofibromatosis themselves or a family history that suggested the Li-Fraumeni syndrome (LFS). CONCLUSION The results of this study suggest that genetic abnormalities play a prominent role in the development of an SMN after therapy for a primary RMS. Chemotherapy with an alkylating agent and radiotherapy play significant roles in the development of an SMN compared with patients who received only one of these therapeutic modalities.

Abstract
PURPOSE We report on long-term health-related problems determined from extended follow-up of 86 children and adolescents who were treated for paratesticular rhabdomyosarcoma on the Intergroup Rhabdomyosarcoma Studies I and II (IRS I-II). PATIENTS AND METHODS Patients were treated between 1972 and 1984, and ages at diagnosis ranged from 10 months to 19 years. The majority of these patients had initial retroperitoneal lymph node dissection (RLND) or sampling performed. RESULTS Problems related to surgical procedures included bowel obstruction in nine patients, loss of normal ejaculatory function in eight, development of a hydrocele in five, and lymphedema of the leg in five. Sequelae related to radiotherapy were difficult to assess with the exception of three patients whose remaining testes were in the field of radiotherapy. In general, kidney and bladder function were normal in patients who received radiotherapy to the paraaortic lymph nodes and/or bladder. Four patients who had abdominal radiotherapy had chronic diarrhea. Two patients had urethral strictures and urethritis. Four patients had bone or soft tissue hypoplasia in the field of radiotherapy. Chemotherapy-related late effects were primarily hemorrhagic cystitis or gonadal dysfunction after cyclophosphamide. A third of the patients who received cyclophosphamide developed hemorrhagic cystitis, and half of these had extended periods of gross hematuria after therapy was discontinued. The testicular size was small in children whose testes were irradiated and in some who received cyclophosphamide. Tanner staging was normal in 45 patients for whom it was recorded. Elevated follicle-stimulating hormone (FSH) values or known azoospermia occurred in more than half the patients for whom data were available. CONCLUSIONS A variety of sequelae related to therapy were determined in this patient population. These findings suggest that some aspects of therapy warrant reevaluation and that improved plans for follow-up care need to be provided.

Abstract
In 1977, a program of early, wide-field radiation therapy (RT) to the central nervous system and repeated lumbar intrathecal (IT) medications along with systemic chemotherapy was begun by the Intergroup Rhabdomyosarcoma Study (IRS) for patients younger than 21 years of age with cranial parameningeal sarcoma and a high risk of meningeal extension. From 1977 until 1987, 149 eligible patients with high-risk cranial parameningeal sarcoma were enrolled in IRS trials. None had evidence of lower extremity or sphincter impairment at diagnosis. Five of the 149 (3.4%) had ascending myelitis at 5.5 to 9 months after the initiation of therapy, with loss of sphincter control and inability to walk; this progressed to severe flaccid quadriparesis and necessitated long-term ventilatory support in 4. All five had received vincristine, dactinomycin, cyclophosphamide, and doxorubicin; four also had received cisplatin and three also had received etoposide. All patients received 4770 to 5500 cGy to the primary tumor, and four patients received 3000 cGy of cranial RT. Three patients received cervical RT and two received spinal RT. The patients also received four to seven courses of IT methotrexate, hydrocortisone, and cytosine arabinoside. Three patients died: one after local tumor recurrence with central nervous system extension and two without known recurrence. In one of the latter patients, the results of an autopsy showed necrosis of the cervical spinal cord and caudal medulla. Although the exact cause of this complication is unclear, no additional cases have been reported to the IRS since the protocol was revised in 1987 to reduce the doses of the IT drugs and to limit them to four courses each.

Abstract
Standard IQ tests were performed in 70 children and adolescents 3.5-10 years (median 5 yrs) after 24 Gy cranial irradiation, with or without concurrent intrathecal methotrexate, for central nervous system prophylaxis of acute lymphoblastic leukemia. Lower IQ scores correlated with younger age, female gender, and concomitant intrathecal methotrexate therapy. Multivariate analysis identified age as the most important determinant of the three factors. The lowest IQ scores were observed in girls who were less than 5 years old at the time of irradiation and who received concurrent intrathecal methotrexate. The observed adverse contribution of simultaneous intrathecal methotrexate therapy on IQ outcome may have significant implications for school performance, peer relationships, and occupational expectations.

Abstract
Preliminary analyses of treatment results and prognostic factors from the first Intergroup Rhabdomyosarcoma Study (IRS I) suggested that alveolar histology and extremity site were among factors associated with an adverse outcome in clinical group I patients whose tumors had been completely resected. A high incidence of alveolar histology among the extremity tumors compounded the problem. These findings prompted an amendment to IRS II shortly after the study opened. Therapy for patients with alveolar extremity tumors in groups I and II was changed to more intensive repetitive pulse vincristine, dactinomycin, and cyclophosphamide (VAC) for 2 years. The outcome of 44 patients who received intensive therapy on IRS II is compared with a control series of 30 patients who were treated on IRS I. The control patients received standard VAC therapy for 2 years or VA for 1 year. Half of group I control patients received local radiotherapy, whereas none was given to group I intensive therapy patients. In both studies group II patients received radiotherapy to the primary tumor site and to identified positive regional lymph nodes. Compared with the control group, patients given more intensive therapy had a longer disease-free survival (DFS) (69% v 43% at 3 years), but this was of marginal significance (P = .06). The overall survival difference (77% v 57% at 3 years) was not significant (P = .23). Despite the limited statistical evidence, there is some indication that intensive therapy improved the prognosis of children with localized alveolar rhabdomyosarcoma (RMS).

Abstract
Bovine leukemia virus (BLV) is the causative agent of enzootic bovine lymphosarcoma. Much speculation continues to be directed at the role of BLV in human leukemia. To test this hypothesis rigorously, a case-control study of childhood acute lymphoblastic leukemia and non-Hodgkin's lymphoma was conducted between December 1983 and February 1986. Cases (less than or equal to 16 years at diagnosis) derived from patients diagnosed at the primary institutions and affiliated hospitals were matched (age, sex, and race) with regional population controls. DNA samples from bone marrow or peripheral blood from 157 cases (131 acute lymphoblastic leukemia, 26 non-Hodgkin's lymphoma) and peripheral blood from 136 controls were analyzed by Southern blot technique, under highly stringent conditions, using cloned BLV DNA as a probe. None of the 157 case or 136 control DNA samples hybridized with the probe. The high statistical power and specificity of this study provide the best evidence to date that genomic integration of BLV is not a factor in childhood acute lymphoblastic leukemia/non-Hodgkin's lymphoma.

Abstract
The results of treatment of 686, previously untreated patients younger than 21 years with rhabdomyosarcoma or undifferentiated sarcoma, who were entered on Intergroup Rhabdomyosarcoma Study-I (IRS-I) were analyzed after a minimum potential follow-up time of 7 years. Patients in Clinical Group I (localized disease, completely resected) were randomized to receive either vincristine, dactinomycin, and cyclophosphamide (VAC) or VAC + radiation. At 5 years, approximately 80% of patients given either treatment were still disease-free and there was no significant difference between treatments in the overall percentages of patients surviving of 93% and 81%, respectively (P = 0.67). Patients in Clinical Group II (regional disease, grossly resected) were randomized to receive either vincristine and dactinomycin (VA) + radiation or VAC + radiation. At 5 years, 72% and 65% of the patients, respectively, were disease-free and there was no evidence of a difference between treatments (P = 0.46). The overall survival percentage at 5 years was approximately 72% for both treatments. Patients in Clinical Groups III (gross residual disease after surgery) and IV (metastatic disease) were randomized to receive either "pulse" VAC + radiation or "pulse" VAC + Adriamycin (doxorubicin) + radiation. The complete remission (CR) rate was 69% in Clinical Group III and 50% in IV, with no statistically significant difference in CR rates between treatments in either group. Those who achieved a CR had a nearly 60% chance of staying in remission for 5 years in Clinical Group III compared with approximately 30% in Clinical Group IV. The overall survival percentage at 5 years was 52% in Clinical Group III compared to 20% in Clinical Group IV (P less than 0.0001). The 5-year survival percentage for the entire cohort of 686 patients was 55%. Survival after relapse was poor, being 32% at 1 year and 17% at 2 years. The risk of distant metastasis was much greater than the risk of local recurrence within each clinical group, and there was no evidence of differing types of relapses between treatments. Primary tumors of the orbit and genitourinary tract carried the best prognosis, whereas tumors of the retroperitoneum had the worst prognosis. The authors conclude that for the therapeutic regimens evaluated there was no therapeutic advantage to including radiation in the treatment of Clinical Group I disease, or cyclophosphamide given as a daily low-dose oral regimen in the treatment of Clinical Group II disease or Adriamycin in the treatment of Clinical Groups III and IV diseases.

Abstract
The results of treatment of 686, previously untreated patients younger than 21 years with rhabdomyosarcoma or undifferentiated sarcoma, who were entered on Intergroup Rhabdomyosarcoma Study-I (IRS-I) were analyzed after a minimum potential follow-up time of 7 years. Patients in Clinical Group I (localized disease, completely resected) were randomized to receive either vincristine, dactinomycin, and cyclophosphamide (VAC) or VAC + radiation. At 5 years, approximately 80% of patients given either treatment were still disease-free and there was no significant difference between treatments in the overall percentages of patients surviving of 93% and 81%, respectively (P = 0.67). Patients in Clinical Group II (regional disease, grossly resected) were randomized to receive either vincristine and dactinomycin (VA) + radiation or VAC + radiation. At 5 years, 72% and 65% of the patients, respectively, were disease-free and there was no evidence of a difference between treatments (P = 0.46). The overall survival percentage at 5 years was approximately 72% for both treatments. Patients in Clinical Groups III (gross residual disease after surgery) and IV (metastatic disease) were randomized to receive either "pulse" VAC + radiation or "pulse" VAC + Adriamycin (doxorubicin) + radiation. The complete remission (CR) rate was 69% in Clinical Group III and 50% in IV, with no statistically significant difference in CR rates between treatments in either group. Those who achieved a CR had a nearly 60% chance of staying in remission for 5 years in Clinical Group III compared with approximately 30% in Clinical Group IV. The overall survival percentage at 5 years was 52% in Clinical Group III compared to 20% in Clinical Group IV (P less than 0.0001).

Abstract
A review of 1415 patients without distant metastasis from the Intergroup Rhabdomyosarcoma Study (IRS) I and II revealed an overall 10% incidence of identified lymphatic spread at diagnosis, whereas 81 of 592 children with localized rhabdomyosarcoma who had grossly complete resection (and therefore with more complete pathologic data) had histologically proven lymphatic spread (14%). The percentage of patients in this latter group with nodal metastases was highest for the prostate (41%), paratesticular sites (26%), and genitourinary sites overall (24%). Sites with a small percentage of proven lymphatic involvement were the orbit (0%), nonorbital head and neck sites (7%), and truncal sites (3%), whereas the percentage of patients with nodal metastases from extremity lesions was 12%. The primary tumor mean diameter was significantly larger in the group with nodal metastases, but there was no evidence of a relationship between lymphatic spread and age, sex, or histologic subtype. Patients with lymph node metastases who had resection had a poorer survival rate (logrank P value = 0.001), with a 3-year survival estimate of 54%, compared with 78% for patients without lymphatic metastases. Patients with extremity lesions and positive lymph nodes also did poorly when compared with patients with normal nodes (P = 0.006), and a similar observation was made for patients with paratesticular sarcoma (P = 0.06).

Abstract
Children with rhabdomyosarcoma (RMS) (1461 total cases) were included in two prospective, randomized protocols conducted by the Intergroup Rhabdomyosarcoma Study (IRS) Committee from November 1972 to June 1983. Treatment assignment was determined by extent of tumor at diagnosis (clinicopathologic group) and not by primary site. Accordingly, 127 patients with RMS confined to the region of the eyelid and orbit were treated by a variety of regimens characterized by initial partial tumor resection followed by concurrent multiagent chemotherapy and orbital radiation therapy. Recurrent tumor developed in ten patients. Seven relapsed initially in the orbit (of whom 4 were salvaged) and three in regional nodes. In addition to the six patients who died of tumor, three died of other causes for a 93% 3-year actuarial survival rate. In 89 children who had subtotal resection or biopsy only, the local control rate with radiotherapy and chemotherapy was 94%.

Abstract
Forty-two children, 6 months to 17 years of age with newly diagnosed soft-tissue sarcomas (gross residual or metastatic), were treated according to either of two pilot protocols that included intensive chemotherapy before irradiation. Vincristine, actinomycin D, cyclophosphamide, and doxorubicin were used in various combinations with cisplatin alone (regimen 35) or with cisplatin plus etoposide (regimen 36) in a 20-week induction treatment; irradiation (4,000 cGy) was delayed until week 6. Fourteen (82%) of the 17 patients on regimen 35 and 15 (60%) of the 25 on regimen 36 had a complete response. Although severe leukopenia was frequent in both groups (88% and 84% of patients), there were only two fatal infections and no early deaths. Other potentially serious toxicity included a greater than 10% weight loss in 52% of the patients and hypomagnesemia in 74%. An average of 75-100% of the prescribed drug doses were administered during the induction phase of therapy. We conclude that this intensified treatment is toxic but feasible to deliver. The higher overall response rate compared to that in the preceding Intergroup Rhabdomyosarcoma Study (69% vs 53%) suggests improved therapeutic efficacy that warrants further evaluation of both regimens.

Abstract
Of a total of 1561 patients registered in the Intergroup Rhabdomyosarcoma Study (IRS) as of May 1983, 78 patients (5%) were younger than 1 year of age. These infants did not differ from the older children (1-20 years of age) in male/female ratio, clinical grouping, or survival rates. Infants younger than 1 year of age had a significantly greater frequency of undifferentiated sarcoma, 18% versus 7% in older children (P less than 0.005). Infants also had a significantly greater proportion of cancers with botryoid pathology, 10% versus 4% in older children (P less than 0.005). When reviewed by the newly proposed IRS cytopathologic classification, there was no difference in pathologic types between the two age groups. Infants younger than 1 year of age had a higher rate of bladder-prostate-vagina primary tumor sites than older children, 24% versus 10% (P less than 0.05). In addition, infants tended to receive less of the prescribed doses of chemotherapy and radiation therapy than older children, and to develop more toxicity to treatment than older children. Despite these differences, the overall survival curve for the two age groups appears to be similar. In contrast to Wilms' tumor and neuroblastoma, in which age (less than 1 year) is a favorable prognostic factor, age does not appear to be an important prognostic factor in rhabdomyosarcoma.

Abstract
Late effects of therapy were evaluated in 50 children surviving orbital rhabdomyosarcoma following treatment on Intergroup Rhabdomyosarcoma Study I. All patients had microscopic or gross tumor present following surgery and subsequently received radiotherapy and various combinations of chemotherapeutic agents. Problems in the eye included infections and functional and structural changes. Decreased vision in the treated eye was the most common functional problem and in most patients related to cataract formation, which occurred in 90% of eyes. Changes in the cornea and retina were also seen. Bony hypoplasia of the orbit and facial asymmetry were present in one half of the children. Gonadal development was normal. Statural growth was retarded in 61% of the patients. All children were in school, with five having learning or behavioral problems. One child developed acute myeloblastic leukemia. The excellent survival in patients with orbital rhabdomyosarcoma provides support for treatment programs that use multiple-agent chemotherapy and radiotherapy and do not include orbital exenteration initially.

Abstract
One hundred one eligible children with soft-tissue sarcomas arising within the retroperitoneal space have been registered on Intergroup Rhabdomyosarcoma Study Committee (IRS) studies I and II and followed for at least 2 years or until death. The most common presenting symptoms and signs were pain in the abdomen or lower extremities, and/or an abdominal mass, usually noted by a parent or a physician seeing the child for other complaints. The median age at diagnosis was 6.5 years and the sex ratio (M/F) 1.7:1. Histologic types were embryonal or botryoid rhabdomyosarcoma (RMS) in 58 patients, alveolar RMS in 8, pleomorphic RMS in 2, undifferentiated sarcoma in 20, extraosseous Ewing's sarcoma in 4 and unspecified sarcoma in 9. Median tumor size was 10 cm, significantly larger than the 7.5 cm noted in the IRS studies as a whole (P less than 0.05). One patient had complete tumor removal (Group I); 12 had grossly complete removal with microscopic residual tumor (Group II). Fifty-one patients had residual local tumor after biopsy or partial resection (Group III) and 37 patients had distant metastases at diagnosis (Group IV). Treatment included surgery, radiation therapy (RT) and combination chemotherapy with vincristine and actinomycin D with or without cyclophosphamide and Adriamycin (doxorubicin) according to protocol. Thirty-nine of 99 patients (39%) had major difficulties in the delivery of specified RT. Seventy patients received sufficient therapy to be evaluable for treatment response. Forty-one (58%) achieved a complete remission and 16 (23%) achieved partial remission. Twenty-four of 41 children (59%) achieving a CR have relapsed. The proportion of children who remained relapse-free at 2 and 3 years of follow-up was 44% or 42%, respectively. Overall, 40 children have developed recurrent sarcoma and the median disease-free interval and overall survival times were 54 and 88 weeks, respectively. Most children experienced severe myelosuppression; there were three early deaths from infection which occurred during granulocytopenic periods. One third of the patients experienced cystitis. Children with soft-tissue sarcomas arising in the retroperitoneal space have a poor prognosis associated with large tumors which, because of location and/or extent (Groups III or IV), are unresectable and difficult to treat.

Abstract
An 8-year-old maternally related relative of three boys who had developed agammaglobulinemia associated with Epstein-Barr virus (EBV)-induced infectious mononucleosis was studied for X-linked lymphoproliferative syndrome (XLP) in 1979. At that time, he demonstrated no striking immunologic aberrations and was seronegative for EBV. Subsequently, immunologic abnormalities including failure to switch from IgM to IgG antibody synthesis after secondary immunization with bacteriophage phi X174 were detected. In 1983, he experienced episodic intracerebral hemorrhages, with the second being fatal. At autopsy, necrotizing vasculitis and aneurysms involving arteries of the central nervous system were observed. Studies of blood obtained immediately before and after death failed to show antibodies to EBV. However, EBV genome was demonstrated in tissues obtained at autopsy by DNA hybridization studies. Fatal lymphoid vasculitis in this patient is unique among boys with XLP in the registry. These findings probably extend the phenotypic expressions of XLP.

Abstract
Histiocytosis X is characterized by the presence of cytoplasmic rod structures called Langerhans' cell granules or X granules (XG). It has been speculated that histiocytosis X is a Langerhans' cell disorder. This ultrastructural study was performed to quantitate the number of XG containing histiocytes in the histiocytosis X lesions. Twenty-four specimens from 22 patients with histiocytosis X were studied: 4 from skin, 5 from lymph node, 11 from bone, 2 from lung, 1 from gingiva, and 1 from cheek. The majority of the histiocytes in histiocytosis X lesions do not contain X granules. The majority of the histiocytes in histiocytosis X lesions do not contain X granules. The percentage of histiocytes with XG in a lesion has no relation to the age of the patient or the organ from which it was obtained, except for skin, where they were quite numerous. The relative percent-age of histiocytes with granules does not correlate significantly with the prognosis of these patients.
