Two groups of rat were given s.c. injections of either monocrotaline or its major detectable metabolite, dehydroretronecine, biweekly for 1 year. Tissues obtained from partial hepatectomies performed at 4 months on a portion of these animals showed that both compounds caused a decided inhibition of mitotic division in regenerating liver.
Rhabdomyosarcomas
developed at the site of dehydroretronecine injection in 51.6% of the rats and in 3.3% of the monocrotaline-treated rats. Metastatic lesions were recorded in 8.3% of these animals. In addition to the above, 10% of the monocrotaline-treated rats developed other tumors that included myelogenous leukemias, hepatocellular carcinomas, and pulmonary adenomas. These data indicate that either monocrotaline or its metabolite dehydroretronecine are capable of causing neoplastic transformations in the tissues of experimental animals.

A primary cerebral
rhabdomyosarcoma
is described in a 48-year-old Negro man. At autopsy two metastatic nodules were present in the liver. A review of the literature indicates that this is a rare and highly
malignant tumor
with no 5-year survival. The multipotentiality of the mesenchymal tissue in the leptomeninges is considered the histogenetic origin of intracranial rhabdomyosarcomas.

Pleural fluid from a child previously treated for
rhabdomyosarcoma
produced colonies in vitro. Cells from these colonies appeared to have the light and electron microscopic appearance of
rhabdomyosarcoma
cells. In this case, the malignant nature of the effusion had been suspected because of the patient's previous history; however, this technique may prove useful in the diagnosis of effusion of unknown etiology.

This report details the clinical experience of 150 patients with rhabdomyosarcomas treated by one group of surgeons. Of the 150 patients, 103 suffered from pleomorphic rhabdomyosarcomas, 40 patients had embryonal rhabdomyosarcomas, and 7 had alveolar cell type of
rhabdomyosarcoma
. The males suffered almost twice as much as the females from this form of
cancer
(96 males to 54 females). The fifth decade had the highest incidence of all rhabdomyosarcomas. The younger patients generally suffered from embryonal rhabdomyosarcomas and the older ones from pleomorphic rhabdomyosarcomas, although age was no barrier to the occurrence of embryonal rhabdomyosarcomas in some of the older patients and pleomorphic rhabdomyosarcomas in some of the younger patients. Caucasians were almost exclusively afflicted by this form of
cancer
(93% of this series). The lower extremity was the most frequent site of the lesion, occurring in 50.7% of the 150 cases. The upper extremity was the second most frequently involved site (28%), and the trunk was the least involved site (21.3%). Of the 150 patients studied, 40 were considered indeterminate. Thirteen patients are alive and free of
cancer
, but were treated less than 5 years ago; 12 patients reported for consultation only. There were 13 who were free of sarcomas at periods in excess of 2 years but were lost to follow-up. Two patients in this series died before the 5-year period, and autopsy revealed the death to be due to causes other than the
rhabdomyosarcoma
. Of the 110 determinate patients, 75 (68%) died as a result of the
cancer
. The 5-year survival rate equals 32%. The fact of the 30% 5-year survival after treatment for recurrences should help dismiss the pessimism which prevails once a recurrence is noted subsequent to major therapy. Age per se had no great effect on prognosis. The poorest results occurred in the 11-20 age range, with a 5-year survival of 15%. This value reflects on increased incidence of embryonal rhabdomyosarcomas which tend to be more malignant and metastasize earlier than do the pleomorphic type. The effect of location upon survival revealed that of 76 patients with involvement of the lower extremity, 34% survived 5 years or longer, and those with sarcomas of the trunk had the poorest survival (26%). The fact that the trunk, by virtue of its anatomy, limits the degree of surgery that can be perfomred, probably helps to explain this difference. The role of radiation therapy and chemotherapy awaits elucidation. Reports of combined surgery, radiation therapy, and chemotherapy are encouraging.

A case of ganglioneuroblastoma associated with malignant mesenchymoma is reported. The tumor originated from the retroperitoneum and was comprised not only of neuroblastoma and ganglioneuroma, but also of typical
rhabdomyosarcoma
, liposarcoma, undifferentiated mesenchymoma, as well as cartilaginous tissue. No distinct border existed between thses different components. The histogenesis of the tumor is discussed. We suggest that the tumor derived from a remnant of neural crest (ectomesenchyme).

Verified breast cancer was present in a father, his mother, and his daughter. His sone had a brain tumor (by history) and his grandson, (ehs sone of the affected daughter), had a histologically verified
rhabdomyosarcoma
. This familial aggregation of cancers (except for leukemia, which is absent) is consistent with a newly described familial breast cancer syndrome. A single pleiotropic, dominantly transmitted gene, possibly interacting with carcinogenic factors, such as an oncogenic virus, may be the cause. A
cancer
-control potential exists for tumor associations such as those exhibited in this kindred, as well as for other
cancer
genetic syndromes where careful consideration is given to all histologic varieties of
cancer
.

Ninety-eight children with solid tumors resistant to conventional chemotherapy received adriamycin 90 mg/m2, either as a single intravenous injection or in 6 divided doses administered every 6 hours. Of the 88 evaluable children, 6 (7%) achieved a complete response and 26 (29%) achieved a partial response. Tumors which demonstrated significant response rates were: neuroblastoma (9/18), Wilms' tumor (7/13),
rhabdomyosarcoma
(4/11), and lymphoma (4/8). The toxicities observed with this regimen included: alopecia, leukopenia, thrombocytopenia, nausea, vomiting, stomatitis, febrile episodes, and ST-segment changes.

Twenty-six cases of childhood rhabdomyosarcoma involving the pelvis were treated at Childrens Hospital of Los Angeles between 1950 and 1972. The median survival of 17 patients treated up to 1970 was 6 months. Of a group of 9 patients treated with intensive chemotherapy (ICG) prior to surgery and/or x-ray therapy, 5 are surviving from 12 to 60 months and have a relative survival rate of 4.5 times that of the mixed therapy group (MTG) (p = 0.01). Deaths have occurred only in patients with Stage IV disease. The use of preoperative chemotherapy with or without x-ray therapy followed by local surgical excision when necessary can be as effective in prolonging the survival of children with pelvic
rhabdomyosarcoma
as those obtained with more traditional approaches; this limitation in use of surgery is likely to preserve the quality of life, should the child live to adulthood.

The treatment of children with
rhabdomyosarcoma
by a combination of surgery, radiotherapy, and chemotherapy has resulted in an improved disease-free survival time. Of 11 children with regional disease eight (72%) remained well, with no evidence of disease, four to 36 months after diagnosis. Chemotherapy for one year with vincristine, actinomycin D, and cyclophosphamide was well tolerated during and after radical radiotherapy and surgery. The natural history of this
malignancy
has been altered in these patients when compared with that in a historical group of 17 children, only two of whom remain alive. There has been no serious short-term toxicity so far.

Three children with
rhabdomyosarcoma
(sarcoma botryoides) of the vagina or uterus were managed by modified radical resection combined with pre- and/or postoperative chemotherapy and high-dose irradiation. This plan of therapy contrasts sharply with the conventional approach: i.e., pelvic exenteration consisting of cystectomy, hystovaginectomy, and oophorectomy, with urinary diversion by ureteroileostomy or ureterosigmoidostomy. Two patients had complete regressions of tumor following preoperative chemotherapy and irradiation. The third patient received no preoperative therapy, but was given postoperative radium implantation, irradiation, and chemotherapy. The surgical approach consisted of hystovaginectomy and oophorectomy without urinary diversion. These patients are free of tumor for 32, 44, and 54 months, respectively. There were no serious toxic reactions to the drugs, nor any significant postoperative urinary tract problems. The results reported here suggest that hystovaginectomy and oophorectomy coordinated with chemotherapy and irradiation is an acceptable alternative to pelvic exenteration in patients with sarcoma botryoides of the vagina or uterus.
