Exenteration is no longer required for most patients who have rhabdomyosarcoma (RMS) of the prostate. This site comprised only about 5% of newly diagnosed cases in the IRS-III (1984-1991). The mean age at the time of diagnosis was 5.3 yrs (range, 0 to 19 years). Most tumors were relatively large, had embryonal histology, and were clinically localized but unresectable without major loss of organ function. The 44 patients with group III tumors (gross residual disease) were treated according to the IRS-III protocol. Forty-three of them underwent biopsy only, and one patient had subtotal resection as the initial procedure. The average number of surgical procedures per patient was two (range, one to five). Six of the 44 patients had no additional surgery. The second-look procedures performed in the other 38 patients included exenteration (14), prostatectomy (7), cystoscopic/perineal needle biopsy (8), laparotomy with biopsy (6), and subtotal excision with bladder salvage (3). Additional surgery was required for four patients, for evaluation of a residual mass, postoperative fistula, ureteral stricture, or small bowel obstruction. Six patients with relapse or residual disease underwent additional chemotherapy and late exenteration (3), prostatectomy (1), or biopsy (2). Four of the six have been cured, one is in treatment for a second malignancy, and the other has residual disease after exenteration. Thirty-six of the 44 patients with group III tumors have been cured (minimum follow-up period, 6 years; range, 6 to 11 years), compared with 23 of the 47 in IRS-II (1978-1984) (P = .001). Two of the six deaths in this group were caused by infection. The bladder salvage rate for those cured of their disease also was better (64% v 57% for IRS-II). The two patients with group IIA tumors were cured by gross primary excision, local radiotherapy, and vincristine and actinomycin therapy. By contrast, all patients with metastatic disease (group IV) died of the tumor. Conservative, delayed surgery, performed after intensive chemotherapy with or without radiotherapy, yields a better cure rate while maintaining a high rate of bladder salvage in children with group III prostatic RMS.
PURPOSE: Prognostic factors for extremity sarcomas have been reported previously, after analysis of Intergroup Rhabdomyosarcomas Studies (IRS) I and II. This report reviews the experience of IRS III (1984-1992), in light of these reported factors, and the pretreatment factors used in the staging system currently being evaluated in IRS IV. The results of treatment of extremity sarcomas in IRS III are reported. METHODS: The charts of all patients entered in IRS III with an extremity-site tumor were reviewed. This group included patients with shoulder girdle and buttock sites. All patients were treated according to IRS III protocols. Survival rates were estimated by the method of Kaplan and Meier, and comparisons among groups of patients were made using a log-rank test. A multivariate analysis was performed to analyze all pretreatment factors that were significant by univariate analysis. RESULTS: Of the 189 patients entered in IRS III with extremity sites, 88 (47%) had the most common alveolar histology. Fifty-nine patients were in group I at the time of presentation (completely resected disease), 48 in group II (microscopic residual disease), 36 in group III (gross residual disease), and 46 in group IV (metastatic disease). By univariate analysis, the significant prognostic factors affecting survival were clinical group, age at time of diagnosis, tumor size, distant metastases, nodal metastases, and local and distant recurrence. By multivariate analysis of pretreatment factors, age at time of diagnosis, nodal metastases, and distant metastases were significant prognostic factors affecting survival; tumor size approached significance. Both the clinical group system and pretreatment staging system (Lawrence/Gehan) predicted significant differences in survival between groups of patients. The lower survival rate among group II and III node-negative patients with a distal tumor (who, with more extensive surgery, could have been in group I) in comparison to group I patients with a distal lesion, approached significance. In patients without distant metastases, survival was significantly different in those patients that had negative nodes from those in whom nodes were not biopsied. CONCLUSION: This review confirms that both clinical grouping and the new pretreatment staging system used in IRS IV can predict the likelihood of survival of children with extremity sarcomas. By multivariate analysis of the elements included in the staging system, nodal metastases, distant metastases, and tumor size were useful in predicting survival. In addition, age was a significant predictor. This study confirms previous suggestions that complete excision with gross and microscopically negative margins is preferable in the treatment of children with extremity rhabdomyosarcomas.
UNLABELLED: Retroperitoneal lymph node dissection (RPLND) was used in 121 Intergroup Rhabdomyosarcoma Study (IRS) III patients with nonmetastatic paratesticular (PT) rhabdomyosarcoma (RMS) to assess retroperitoneal lymph node (RPLN) involvement so as to determine the need for x-ray therapy (XRT). Clinical node evaluation (CNE) was accomplished by a computed tomography (CT) scan in 105 and a sonogram in six. Pathological node evaluation (PNE) was performed in 113: lymphadenectomy (9 bilateral, 85 unilateral) and biopsy in 19. Vincristine and actinomycin D were used for 1 year postoperatively in 89%; all patients who had positive PNE received RPLN XRT. This study compares CNE with PNE and evaluates predictors of relapse and survival. FINDINGS: There were clinically negative nodes (cN0) in 81% of the 121 patients. Among cN0 patients, 14% had positive nodes (pN1). Of the clinically positive (cN1) patients, 94% had pN1. RPLN relapse occurred in only two of the 121 patients. Initially both had cN0 and one had PNE that was negative. For all 121 patients, the 5-year survival was 91%. For cN0 patients, the 5-year survival was 96% compared with 69% for cN1 patients (P < .001). Among the children in whom treatment failed, nodes were cN1 in 5 of 11 (45%) compared with 15 of 107 (14%) in those whose treatment did not fail (P < .008). CONCLUSIONS: (1) Results of RPLN imaging studies were negative in 81% of patients with PT RMS (specificity 99%, sensitivity 57%). (2) RPLN recurrence is uncommon (even when RPLN are initially involved) if regional XRT and appropriate chemotherapy are used.(ABSTRACT TRUNCATED AT 250 WORDS)
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.
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).
Twenty-one heterosexual women who were or had been married to bisexual or homosexual men and had children by them responded to a 28-page questionnaire that explored their experiences as wives and mothers. All of the married women expected a lasting, monogamous marriage. Only three had partial knowledge of their husband's sexual orientation before marriage. All of them went through a painful grief reaction when they learned that their husbands had emotional or sexual, or both, attachments to other men. The suffering was aggravated by feeling deceived or stupid for not having guessed the truth. What made it difficult for them to seek support from family and friends was the fear of encountering social disapproval or ostracism. They were afraid for themselves, their husbands, and their children. At the time of the study 11 of the 21 women were still married and living with their husbands, but most of them felt unsure that the marriage would last. Ten were in transition, separated, or divorced. Only three of the still married wives had complete confidence in the future stability of their relationships. These marriages were characterized by good communications, husbands who considered themselves bisexual, and an open marriage contract whereby wives could have heterosexual affairs. Findings cannot be generalized from this small convenience sample, but will hopefully encourage further research. The writers are also soliciting more subjects to enlarge the sample.
To overcome the problem of inadequate mixing of gastrointestinal (GI) tract contents with conventional high-density oral contrast agents in abdominal computed tomography (CT), a flavored 12.5% corn oil emulsion (COE) was tested as an oral contrast agent in 62 patients. The results were compared with those obtained from 105 patients who received high-density oral contrast agents. A simple patient preparation regimen for the COE was developed, which appears to be reasonably well tolerated by the patients and yields diagnostic studies comparable to those obtained with conventional agents. Use of the COE resulted in consistent discrimination of the GI tract and depiction of the GI wall. Preliminary data suggest that it may be particularly useful for CT evaluation of the stomach, duodenum, and pancreas; in patients suspected of having solid tumors; and in thin people.
Ratios of fetal abdominal circumference to femur length (AC/FL) and thigh circumference to femur length (TC/FL) have been suggested as indices of fetal nutrition. Birthweight, skin-fold thickness, and ponderal index are accepted neonatal indices of nutrition. The purpose of this study was to compare fetal to neonatal indices of nutrition. In 52 patients in term labor, fetal abdominal circumference, thigh circumference, and femur length were measured ultrasonographically. Neonatal skin-fold thickness was calculated as the average of tricipital, subscapular, abdominal, and anterior thigh measurements determined with Harpenden skin-fold calipers. Linear correlation analysis demonstrated a significant relationship between AC/FL and ponderal index (r = 0.340, P = 0.028) and between TC/FL and ponderal index (r = 0.368, P = 0.007). Neither AC/FL nor TC/FL were significantly related to birthweight or skin-fold thickness. These data suggest that the diagnostic reliability of antenatal studies of fetal biometric ratios may be enhanced by using the ponderal index as a neonatal endpoint rather than birthweight or skin-fold thickness.
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%.
A case of perforation of the sigmoid colon by a Cu-7 intrauterine contraceptive device (IUCD) complicated by septic pelvic thrombophlebitis is presented.
Twenty-one patients with bilateral Wilms' tumor are reviewed and the details of diagnosis, therapy, and survival presented. All patients had an abdominal mass at the time of diagnosis. Associated findings included hypertension, aniridia, and genitourinary anomalies. Favorable histologic features were found in all simultaneously occurring tumors and in the initial tumor in nonsimultaneous tumors. Eleven of the 18 patients with simultaneously occurring tumors survived for at least 2 years, for an overall 2-year survival rate of 61%, which was similar to the 2-year survival rate of 60% found in a review of 61 other simultaneously occurring bilateral Wilms' tumors reported in the literature since 1971. Two "front-end" factors that affected prognosis were the patient's age and the stage of the most advanced tumor at the time of diagnosis. A significantly better survival was found in children whose tumor was diagnosed before the age of 2 years and in patients who had Stage I or II disease in the most advanced tumor, as compared with those who had Stage III or IV disease. The overall survival rate in this series and in the literature review is much poorer than that reported for bilateral Wilms' tumor in the National Wilm's Tumor Study; some possible reasons for this are given. The authors' current approach to diagnosis and therapy is reviewed.
The intergroup study of involved-field (IF) radiotherapy, IF radiotherapy plus MOPP chemotherapy, and extended-field (EF) radiotherapy for treatment of Hodgkin's disease in children has assessed 305 patients. Of these, 279 were "not ineligible" (no mediate cause for disqualification). Among 223 randomized patients, 144 were evaluable, 131 had documentation of complete or partial remission, 20 of the remitters relapsed, and two died. Among 62 nonrandomized patients with favorable presentations (unilateral upper neck, unilateral inguinal, or massive mediastinal disease), 29 had documented remission, two relapsed, and none died. Length of initial disease control (LIDC) was used to measure duration of response. LIDC was best in patients given IF plus MOPP, and 95% are disease free. EF was better than IF radiotherapy (P = 0.004). Of the disease characteristics prognostic for response (stage, histologic subtype, and presence of symptoms), only the last factor had a statistically significant effect on LIDC (P = 0.004). Ninety-six percent of the patients survive. Using criteria developed by the committee, 23% of the staging procedures reviewed were nonevaluable and 28% of the radiotherapy treatments were nonevaluable. The necessity for criteria for evaluation of staging and treatment is certain. Length of followup is too short for correlations of treatment with significant late effects and for relevant therapeutic recommendations.
Fifty-eight children with genitourinary rhabdomyosarcoma are reported. Lesions involved the bladder (22), prostate (14), vagina/uterus (6), and paratesticular tissues (16). Fifteen of 58 had positive sampling of regional lymph nodes. Eleven of 15 received radiation to no more than 4500 rad in most cases, and 9 of 11 are diseases free. Two of 15 had no radiation and are disease free also. Twenty-three of 58 had negative nodes. Six of 23 had radiation to these nodal areas and 4 of 6 are disease free. Fifteen of 17 patients had no radiation and are disease free also. Sixteen of 20 patients with no node sampling are disease free; 9 of 16 had radiation but 7 of 16 did not. All patients in the Study had intensive systemic maintenance chemotherapy. One 1 patient failed in regional nodes despite 4500 rad to these node echelons. We suggest chemotherapy and radiotherapy, not to exceed 3500 rad in four weeks, to known residual disease including regions from which positive nodes have been obtained.
