Primary chemotherapy with or without radiation therapy and/or surgery for children with localized sarcoma of the bladder, prostate, vagina, uterus, and cervix. A comparison of the results in Intergroup Rhabdomyosarcoma Studies I and II.

A major objective of the second Intergroup Rhabdomyosarcoma Study (IRS-II) (1978 to 1984) was to preserve the bladder without compromising the survival of children with localized genitourinary sarcomas arising in or near the bladder. After incisional biopsy, 109 patients with localized, gross residual sarcoma of the prostate (43 patients), bladder (43 patients), vagina (20 patients), or cervix/uterine corpus (3 patients) were treated with vincristine, dactinomycin, and cyclophosphamide (VAC). After two to four drug courses, radiation therapy and/or surgery were used to treat patients with residual or recurrent tumor. The 3-year survival rate of patients treated on this primary chemotherapy regimen (70%) was similar to that of the primary surgery regimens of IRS-I (78%; P = 0.46), but the 3-year disease-free survival rate was significantly inferior (52% versus 70%; P = 0.02). Since the IRS-II encouraged bladder preservation at the onset of therapy, the percentage of patients with bladder and prostate tumors who retained the bladder was initially substantially higher in IRS-II (97%) than in IRS-I (58%). However, the percentages of 95 patients with bladder-prostate (BP) tumors in IRS-II who retained the bladder and were alive at 2 and 3 years after starting treatment were only 33% and 22%, respectively, compared with 26% and 23%, respectively, in the 66 patients with BP tumors in IRS-I. Thus, sequential treatment with primary chemotherapy, followed by radiation therapy and/or surgery as given in IRS-II, failed to improve the eventual bladder salvage rate.

Soft tissue sarcoma of the perineal region in childhood. A report from the Intergroup Rhabdomyosarcoma Studies I and II, 1972 through 1984.

Thirty-six previously untreated patients younger than 21 years of age with sarcoma arising in the perineal region were entered on the Intergroup Rhabdomyosarcoma Studies (IRS) I and II from 1972 through 1984. The tumor histologic subtype was alveolar rhabdomyosarcoma (RMS) in 20 patients (56%), embryonal RMS in 11 patients (30%), and other types of sarcoma in 5 patients (14%). Fifteen children had grossly complete surgical excision (Clinical Groups I and II), and 15 had localized gross residual tumor (Group III) after initial operative management. Six patients had distant metastases (Group IV) at diagnosis. Twelve patients without distant metastases underwent regional lymph node biopsy; tumor involvement was found in six. Subsequent treatment consisted of chemotherapy with vincristine (VCR) and dactinomycin (AMD) for all patients; patients in Groups III and IV also received cyclophosphamide (CYC) with or without Adriamycin (ADR) (doxorubicin; Adria Laboratories, Columbus, OH). Radiation therapy (RT) was administered to patients in Clinical Groups II, III, and IV. Overall, 28 (78%) patients achieved a complete clinical response. The 3-year disease-free survival rate for these patients was 42%, compared with 52% for all other patients in the combined IRS I and IRS II series (P = 0.44). The overall 3-year survival rate was 59%, compared with 64% for all other patients in IRS I and IRS II (P = 0.48). Aggressive treatment is needed in children with perineal sarcoma to improve their prognosis.

Secondary surgical procedures to evaluate primary tumor status in patients with chemotherapy-responsive stage III and IV sarcomas: a report from the Intergroup Rhabdomyosarcoma Study.

Fifty children with clinical group III (localized, but unresected) or clinical group IV (disseminated) soft tissue sarcomas were entered in a trial to determine if the addition of etoposide and cisplatin to standard chemotherapy regimens and irradiation (4,000 cGy) would be tolerated by pediatric patients. Responding patients had a secondary surgical procedure performed after approximately 20 weeks of therapy for the purpose of establishing histological response, determining its extent, and removing residual tumor tissue, when feasible. Such procedures were performed in 29 of 50 (58%) of these patients, ie, 20 of 31 (65%) of those in group III, and nine of 19 (47%) of those in group IV. Surgical procedures consisted of exploration of the site and biopsy (only) in 16 patients; grossly complete tumor excision in nine; and subtotal tumor excision in four. In nine patients (six in group III, three in group IV) apparent total excision of a previously unresected primary tumor mass was accomplished at second surgery. One distant but no local relapse has occurred in this group, and eight of nine have survived (five of six with identified tumor in the specimen) for a duration of 232 to 348 weeks (six greater than 260 wks), suggesting that among patients with primary tumors in selected sites, with either stage III or stage IV disease, excision of residual masses following intensive chemotherapy/radiotherapy regimens may favorably influence outcome. Local relapse subsequently occurred in seven of 18 patients in whom tumor tissue could not be identified in biopsy specimens or in excised masses taken from the primary site at second surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

Partial cystectomy in the management of rhabdomyosarcoma of the bladder: a report from the Intergroup Rhabdomyosarcoma Study.

Among 154 children with primary vesical rhabdomyosarcoma entered in the IRS (1972 to 1986), tumor excision constituting a partial cystectomy was performed in 33. These procedures were performed in the following situations (1) as an initial operation for localized disease (22); (2) as a secondary procedure for localized disease following chemotherapy (CT) or CT/irradiation response (6); and (3) as an initial operation in the presence of disseminated abdominal disease (5). Partial cystectomy included full-thickness resection of 15% to 80% of the bladder wall. Ureters were reimplanted or revised in two patients. The 33 patients undergoing partial cystectomy were in the following clinical groups: I, total excision (10); II, gross excision with "microscopic residual" or positive nodes (8); III, subtotal excision (10); and IV, tumor dissemination (5). Patients in clinical groups I and II received vincristine and actinomycin-D (VA) or VA + cyclophosphamide (VAC) +/- adriamycin (ADR). Patients in groups III and IV received the same agents +/- cisplatin. Irradiation (2,000 to 5,000 cGy) was administered to 18 patients (55%) in groups II to IV. Six relapses occurred among 28 patients with localized disease, and one among five patients with dissemination; all resulting in progressive disease and/or death. Estimated 3-year survival following partial cystectomy (79%) is similar to that for all patients with primary bladder tumors (78%). In contrast with the total group, in which the majority of survivors have eventually required total cystectomy; 25 of 26 survivors of partial cystectomy have functional bladders from 146 to 686 weeks (median, 356 weeks) from study entry.(ABSTRACT TRUNCATED AT 250 WORDS)

Langerhans' cell histiocytosis (histiocytosis X): experience at the Children's Hospital of Philadelphia, 1970-1984.

Sixty-four patients with biopsy-proven Langerhans' cell histiocytosis (LCH, formerly designated as histiocytosis X) were managed at the Children's Hospital of Philadelphia from 1970 through 1984. Their median age was 3 yr (range, 0.1-22 yr). Thirty-three patients had localized lesions affecting a bone (27) or soft-tissue region (6). Twenty-two patients had multifocal disease affecting bones (17) or soft, nonosseous tissues (5). None of these patients had evidence of dysfunction of liver or lungs, and none had abnormal peripheral blood cell counts. The remaining nine patients had multifocal LCH plus dysfunction of liver or lungs (6) or abnormal blood counts (3). Treatment consisted primarily of surgical excision for patients with localized lesions and of drug therapy with or without irradiation and surgery for those with multifocal disease. Recurrence was infrequent (7%) in those with localized LCH, and all survived. Recurrence was frequent (74%) in those with multifocal LCH but without organ dysfunction or abnormal blood counts, but 21 of the 22 survived. By contrast, only three of the nine patients with organ dysfunction or abnormal blood counts survived. Thus organ dysfunction and abnormal blood counts at diagnosis emerged as the major adverse prognostic factors in children with LCH.

Disease patterns and survival rate in children with metastatic soft-tissue sarcoma. A report from the Intergroup Rhabdomyosarcoma Study (IRS)-I.

The patterns of disease extent, response to treatment, and survival rates were examined in 129 children registered as metastatic (Group IV) soft-tissue sarcoma patients on the Intergroup Rhabdomyosarcoma Study (IRS)-I protocol from November 1972 through October 1978. The patients' ages at diagnosis ranged from 3 months to 21 years (median, 10.5 years); 72 were male patients and 57 were female patients (male-to-female ratio, 1.3:1). The tumor arose in an extremity in 34 patients, the head and neck (exclusive of the orbit) in 27, the genitourinary tract in 25, the retroperitoneum or pelvis in 14, the trunk in 12, the intrathoracic region in nine, the hepatobiliary system in four, the perineum in two, and the orbit in two patients. The histologic types of soft-tissue sarcoma confirmed by the pathology review committee were embryonal rhabdomyosarcoma in 68 patients, alveolar rhabdomyosarcoma in 41, undifferentiated sarcoma in 14, embryonal-botryoid in two, pleomorphic in one patient, and other sarcoma in three patients. Of 105 patients who were confirmed in Group IV and had complete information concerning sites of metastatic deposits, 53 patients presented with metastases restricted to only one anatomic region or tissue; the other 52 had diffuse metastases. The most common sites of distant tumor deposits were the lungs, bone marrow, and other soft tissues. After treatment with vincristine, dactinomycin, and cyclophosphamide with or without Adriamycin (Adria Laboratories, Inc., Columbus, OH) and radiation therapy, 65 (50%) of the 129 eligible patients achieved complete disappearance of all detectable tumor. The likelihood of achieving and maintaining a complete response for 2 years was highest among patients whose tumors originated in the genitourinary tract, retroperitoneum-pelvis, or the hepatobiliary or perineum regions. Thirteen of these 45 children (29%) are alive and disease-free at a minimum of 2 years after initiation of treatment. Only 10 of the other 84 (8%) are surviving disease-free at 2 years (P = 0.02). The presence of restricted rather than diffuse metastases at diagnosis (P = 0.02) was the only other characteristic significantly related to long-term complete remissions. One hundred and two patients (79%) died at a median of 47 weeks after diagnosis, 92 from sarcoma and ten from other causes.(ABSTRACT TRUNCATED AT 400 WORDS)

Clinical staging and treatment results in rhabdomyosarcoma of the female genital tract among children and adolescents.

From 1972 to 1984, 47 children and adolescents with primary tumors of the female genital tract were treated with eight different Intergroup Rhabdomyosarcoma Study (IRS I-II) protocols. These included patients with vaginal (28), uterine (ten), or vulval (nine) rhabdomyosarcoma or undifferentiated sarcomas. The mean age of patients with primary vaginal tumors was younger than 2 years. All were of the embryonal histologic subtype. The majority of these patients were treated with initial chemotherapy (vincristine, dactinomycin, +/- cyclophosphamide, +/- Adriamycin [(ADR) doxorubicin]) followed by delayed hysterectomy and/or partial vaginectomy. Among 26 patients with localized vaginal tumors, there have been six relapses resulting in one tumor-related death and one therapy-related death. The five patients with nonfatal relapse have been disease-free for from 2.5 to 6.5 years (mean, 4.4 years) since salvage therapy was commenced. The 19 patients without relapse have been continuously disease-free for 1.5 to 12 years (mean, 5.34 years: median, 6 years). No patient that received ADR initially relapsed. Ten patients, with a mean age greater than 13 years, had primary uterine sarcomas and were treated by the same chemotherapy regimens. Six with polypoid localized lesions, removed before chemotherapy, have remained disease-free for 2.5 to 6.5 years. Four, with more extensive local lesions or disseminated disease, treated with chemotherapy only, died 2 to 11 months from diagnosis. Nine patients with rhabdomyosarcomas of the vulva (age, 1-19 years) were managed by the same chemotherapy regimens +/- radiotherapy. Resection was carried out initially or after chemotherapy. Eight of these have been disease-free from 4 to 10 years (mean, 6.4 years); and one is alive with probable disease at 2.5 years.

Interstitial radiation therapy in the treatment of childhood soft-tissue sarcomas.

Between 1971 and 1985, 12 children and adolescents aged 0.7 to 19 years (median 4.7 years) with localized residual soft-tissue sarcomas (STS) underwent interstitial radiation therapy (IRT) at our institution. Eight received IRT as a component of initial therapy, and four were treated for recurrent or persistent disease. Tumor sites were head and neck (6), pelvis (4), extremity (1), and retroperitoneum (1). The radionuclides employed were Iridium-192 (9), Iodine-125 (2), and Californium-252 (1). The median prescribed dose in the Iridium-192 group was 3960 cGy (1955-7300). Seven of eight children receiving IRT during initial therapy have maintained local control, and six remain without evidence of disease for a median follow-up time of 5.8 years (2.0-16.0). One of the four patients treated for recurrent disease is free of disease after salvage surgery, and the other three are dead of disease. Multidisciplinary evaluation of the nine patients with more than 2 years of follow-up revealed functional and cosmetic effects of IRT to be minimal. IRT can be an effective method of delivering high dose irradiation in childhood sarcomas while reducing the deleterious effects in adjacent normal tissues.

Interferon-alpha n1 in children with recurrent acute lymphocytic leukemia: a phase I study of pharmacokinetics and tolerance.

Twelve children ages 3-15 years with relapsed acute lymphocyte leukemia (ALL) were treated over 25 days by intravenous or intramuscular administration of interferon-alpha n1 (IFN-alpha n1). Single doses ranged from 2.5 to 15 MU/m2, total doses from 60 to 200 MU/m2. Serum pharmacokinetics were determined following administration of two different doses. Calculation of area under serum concentration curve (AUC) values showed increased AUC with increased dose. Mean AUC (h x U/ml) ranged from 735 to 3986 at doses of 2.5 and 15 MU/m2, respectively, when given intramuscularly. AUC for i.v. and i.m. administration were similar. Side effects reported most commonly were fever and chills in 11 of 12 patients, nausea/vomiting in 7, mild lethargy in 3, and injection site pain in 4 of 9 treated i.m. Reversible hepatotoxicity occurred in the 3 patients receiving the highest doses, 10 then 15 MU/m2. Three patients had clinically significant bleeding associated with mildly increased coagulation studies and an additional three patients had increased coagulation parameters without bleeding. Four patients were considered to have stable disease; one treated at the highest dose level had clearance of peripheral blasts but remained in bone marrow relapse. IFN-alpha n1 as used in this study produced detectable blood levels with associated side effects. A Phase II intramuscular trial is recommended.

Paratesticular sarcoma in childhood and adolescence. A report from the Intergroup Rhabdomyosarcoma Studies I and II, 1973-1983.

This article reports on the diagnostic features, radiographic findings, staging, operative management, treatments, and treatment results for 95 children (mean age, 10 years) with paratesticular sarcoma; they were treated on the Intergroup Rhabdomyosarcoma Study (IRS) I and II protocols. Embryonal rhabdomyosarcoma (RMS) was the most common histologic subtype (97% of cases). Patients were randomly assigned to receive various therapeutic regimens according to IRS protocols. Among 81 patients (85%) with localized disease, most (57) were in Clinical Group I (localized, completely excised tumors), and 20 were in Group II (gross excision with tumor-involved, regional retroperitoneal lymph nodes or microscopic residual). Only four were in Group III (gross residual disease in the primary site or retroperitoneal lymph nodes). Three of them achieved a complete response (CR) after induction therapy and two then relapsed. The relapse-free survival (RFS) estimates at 3 years from diagnosis were 93% in Group I and 90% in Group II. Distant metastases were present at diagnosis in only 14 patients. Twelve of them achieved CR, but four subsequently relapsed; their 3-year RFS estimate was 67%. Overall, survival rates among the 95 children were excellent (89% at 3 years) compared to the entire IRS series (63%). Treatment with radical orchidectomy and chemotherapy was sufficient for Group I patients. Orchidectomy, chemotherapy, and radiation therapy were highly effective in Group II patients and in a large proportion of those with more advanced tumors. Recommendations for the diagnostic examinations and management of future patients with paratesticular sarcoma are given.

Malignant ovarian tumors in children and adolescents.

Eighteen patients aged 4 to 18 years (median, 10 years) were treated at the Children's Cancer Research Center of The Children's Hospital of Philadelphia (CHP) from September 1973 to September 1983 for malignant ovarian tumors. The pathologic categories were endodermal sinus tumor (eight patients), embryonal carcinoma (three patients), pure dysgerminoma (three patients), adenocarcinoma (three patients), and malignant granulosa-cell tumor (one patient). In 1973 and 1975, respectively, two patients with endodermal sinus tumors were treated with surgical removal with or without radiation therapy (RT) and chemotherapy with vincristine (Vc) and actinomycin D+ cyclophosphamide + Adriamycin (Adria Laboratories, Columbus, OH) (ACAdr); both developed local recurrence within 12 months and died of tumor. Since 1977, four of six patients with endodermal sinus tumors have been managed successfully with surgery followed by chemotherapy with cisplatin (P), bleomycin (B), vinblastine (Vb), and ACAdr; none received RT. One died of recurrent tumor and the other died of congestive heart failure attributed to Adriamycin (Adr). All three patients with embryonal carcinoma were well after surgical excision alone (one patient) or surgery and chemotherapy with cisplatin + bleomycin + vinblastine (PBVb) + ACAdr (two patients). Treatment of the remaining seven patients included excision alone (two patients) or excision and chemotherapy (five patients) with various combinations of Vc, ACAdr, and P. One patient with granulosa-theca cell tumor also received whole abdominal RT (3000 rad by external beam), and died of congestive heart failure attributed to Adr. The other six children were free of detectable tumor 16 months to 8 years from diagnosis. Chemotherapy with PBVb and actinomycin D + cyclophosphamide (AC) should be used in the postoperative management of young persons with malignant ovarian tumors. Adr is of doubtful value and may be considerably toxic. RT is of limited use and usually is not indicated.

Improved prognosis with intensive treatment of children with cranial soft tissue sarcomas arising in nonorbital parameningeal sites. A report from the Intergroup Rhabdomyosarcoma Study.

In the first Intergroup Rhabdomyosarcoma Study (IRS-I), it was found that, of 57 patients with nonorbital cranial parameningeal sarcoma treated from 1972 to 1976, 20 patients (35%) developed meningeal sarcoma and 90% (18/20) died of this complication. Since about half of these 20 patients had received inadequate radiation therapy and all had radiation therapy delayed until week 6, the treatment program was modified in December 1977 to begin radiation therapy on day 0 to the entire neuraxis and the primary tumor for all patients presenting with one or more risk factors indicating a high risk of meningeal involvement, and to administer periodic intrathecal medications to the same patients. The risk factors were intracranial extension of tumor, bony erosion at the cranial base, and cranial nerve palsy. In this report, the prognoses of two groups of patients with nonorbital cranial parameningeal sarcoma are compared: 95 patients treated before modification of the protocol in December 1977 with chemotherapy and nonintensive meningeal radiotherapy (preintensive group) and 68 patients treated subsequently with intensive meningeal radiotherapy and chemotherapy (intensive group). All patients received vincristine and actinomycin D (dactinomycin) with or without cyclophosphamide and Adriamycin (doxorubicin), according to the protocol. Radiation therapy consisted of 4000 to 5500 rad to the primary tumor in 5 to 6 weeks for most patients. The intensively treated patients also received intrathecal drugs via lumbar puncture and whole cranial or craniospinal radiation when one or more meningeal risk factors were present. In the preintensive group, the complete remission rate was 68% (65/95); the percentages of patients tumor free or alive at 3 years were 33% and 41%, respectively. In intensively treated patients, the complete remission rate was 76% (52/68); the percentages of patients tumor free or alive at 3 years were 57% and 68%, respectively. The improvements in the percentages of intensively treated patients tumor free or surviving were highly statistically significant (P less than 0.01 for both comparisons). Within the intensive treatment group, meningeal involvement at diagnosis was an unfavorable prognostic sign, since patients with no meningeal involvement had much better tumor-free survival at 3 years (81% vs. 51%) and survival (90% vs. 57%) than patients with evidence of meningeal involvement; the differences were highly statistically significant (P = 0.01).

Pediatric orofacial and laryngopharyngeal rhabdomyosarcoma. An Intergroup Rhabdomyosarcoma Study report.

Eighty-nine children with localized rhabdomyosarcoma of orofacial and laryngopharyngeal sites were treated in accordance with the first and second Intergroup Rhabdomyosarcoma Study (IRS) protocols (IRS-I and IRS-II) between 1972 and 1984. Treatment included surgery (or biopsy) and chemotherapy for all patients and radiotherapy in the majority. The actuarial estimate of the three-year survival rate for all patients was 83% and did not differ significantly by primary site, histologic findings, or presence of adenopathy. A trend for a worse survival rate was seen in clinical group III patients and in those less than 5 years of age at diagnosis. Factors associated with an increased risk of local/regional relapse included omission of radiotherapy and a radiation dose of less than 40 Gy (4000 rad). We conclude that treatment of these patients as recommended in the IRS-I and IRS-II protocols results in very good local and regional tumor control and survival rates. Salvage therapy for local/regional recurrence may yield long-term remission and possibly cure.

Intensive chemotherapy including cisplatin with or without etoposide for children with soft-tissue sarcomas.

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.

Yolk sac carcinoma of the testis in children.

We reviewed the records of 11 patients with yolk sac carcinoma of the testis seen at the Children's Hospital of Philadelphia from 1971 through 1983. Each child was less than 2 years old at diagnosis, and each had stage I disease (localized to the testicle). Initial management consisted of radical inguinal orchiectomy in all 11 patients. Four patients then underwent retroperitoneal node dissection and none had pathological evidence of retroperitoneal tumor spread. After primary surgical management 5 patients received no further initial treatment. Of these 5 patients 3 are alive with no evidence of disease at 1.5, 2.7 and 4.5 years after diagnosis. The tumor recurred in 2 patients, 1 of whom was salvaged with pulmonary radiation therapy and chemotherapy. The other 6 patients received chemotherapy postoperatively and only 1 has suffered relapse. Over-all, of 3 patients in whom pulmonary metastases developed 1 died of tumor and 1 died of treatment-related pneumonopathy. Our experience and that of others have led us to conclude that patients with localized disease and normal postoperative serum alpha-fetoprotein levels do not benefit from retroperitoneal node dissection, postoperative abdominal irradiation or chemotherapy. Patients with retroperitoneal nodal involvement, widely metastatic disease or recurrent disease can be treated successfully with chemotherapy and in some cases with radiation therapy.

Inefficacy of cisplatin and etoposide as salvage therapy for children with recurrent or unresponsive soft tissue sarcoma.

Cisplatin (CPDD) and etoposide (VP-16) have activity as single agents in children with recurrent soft tissue sarcoma, with response rates approximating 20%. Sixteen evaluable patients with soft tissue sarcoma, 0.9 to 16 years of age, were treated with a combination of CPDD (75-100 mg/m2 iv X 1) and VP-16 (100-150 mg/m2/day iv X 3-5) every 3 weeks after recurrence or failure to respond to standard therapy. Toxicity consisted of vomiting and myelosuppression. There were no complete responses, and only two children (12.5%) had partial responses lasting 6 weeks. Every patient died of progressive tumor. CPDD and VP-16, as given on this study, had minimal activity.
