From 1950 through 1974, a total of 108 cases of primary intestinal leiomyosarcoma were seen at the Mayo Clinic. Most of these uncommon tumors occurred in the fifth and sixth decades of life, and more of them in men than in women (2.6:1). There were 73% in the small bowel, 25% in the large bowel, and 2% in the anus. Gastrointestinal bleeding and pain were the two most common signs at presentation, and they led to surgical exploration in all cases where they appeared. By the time surgery was performed, only 48% of the tumors could be resected with hope of cure. Within that group of cases, 50% of the patients survived 5 years, but only 35% survived 10 years, late recurrence being common. The histologic grade of the tumor affected survival to erroneous early optimism in prognosis.

A case report and review of the problem of duodenal leiomyoma are presented. Although these lesions are rare and usually asymptomatic, they can present with symptoms of hemorrhage, obstruction, pain, and perforation. Barium roentgenographic examination may show filling defects of compressive lesions. Angiography shows a hypervascular, encapsulated lesion. Endoscopy may reveal a submucosal mass with central depression. At operation, it is important to distinguish the benign leiomyoma from leiomyosarcoma.

A case of leiomyosarcomatosis is presented. Over a period of 15 years the patient underwent seven operations to remove eleven tumours, the largest as big as a football, before dying of widespread metastases: between operations the patient was remarkably well. The disease was almost certainly of uterine origin from apparently benign fibroids, and photomicrographs are provided as supportive evidence. The various modes of presentation of abdominal leiomyosarcoma--mass, pain, obstruction, fistula, anaemia--are illustrated in the case report. The value of repeated palliative surgery in such cases is emphasized.

Leiomyosarcoma of vascular origin are rare tumors arising most frequently from the inferior vena cava (IVC). We report on three patients one of whom underwent definitive resection. These tumors most commonly involve the upper segment of the IVC, and appear with manifestations of the Budd-Chiari syndrome. Lesions at this level are not amenable to surgical therapy. Tumors of the middle and lower segments of the IVC usually cause right-sided pain. Diagnosis is difficult, but is best approached preoperatively by angiography and vena cavography. Optimal therapy of lesions at these levels is surgical resection. Resection of the IVC below the hepatic veins is possible with renal function preserved by collateral drainage of the left renal vein.

As part of an ongoing Phase I/II study at Duke University Medical Center investigating the toxicity and efficacy of external beam radiotherapy plus hyperthermia for deep-seated, locally advanced or recurrent solid tumors, 12 patients with prostate malignancies (adenocarcinoma--11, leiomyosarcoma--1) were treated with radiotherapy plus hyperthermia. Hyperthermia was given after radiotherapy using a Radio Frequency Phase/Amplitude Control Sigma 60 annular phased array device. All patients had simultaneous temperature measurements made in the rectal lumen and within the prostate during at least one hyperthermia session. Intraprostate thermometers were placed via a unique method described herein using both computerized tomography scan and a rigid sigmoidoscope for guidance. We were able to achieve the desired tumor temperature of > or = 42.5 degrees C in only 1/28 (3.5%) of hyperthermia treatments. Subjective symptoms of pain and/or pressure limited power deposition in 79% of hyperthermia treatments. Higher temperatures were achieved in the distal rectum than in the prostate in all treatments, although the differences were not statistically significant. This temperature differential could not be compensated by using phase and amplitude steering. Rectal temperatures adjacent to the prostate were predictive of prostate temperatures. We conclude that using this regional heating technique we were unable to demonstrate an ability to get an advantageous temperature differential between the prostate and normal tissue. This technique is not useful as an adjuvant to radiation therapy for prostate cancer. The usefulness of other regional heating techniques and devices should be explored.

Sarcoma of the uterus accounts for less than 1 per cent of uterine neoplasms but is responsible for more than 15 per cent of deaths. However, histological or clinical malignancy features are poorly understood, in particular those which differentiate sarcomas from leiomyomas. This study involved 16 cases, seen during 8 years in two gynecology clinics in Iasi (Rumania) and chosen according to histological diagnosis. Ten leiomyomas were also chosen for comparison of symptomatology. The malignancy criteria studied--vascular invasion, cellular density, number of mitoses and histological type (most often leiomyosarcoma: 8 out of 16)--were used to compare sarcomas with suspect leiomyomas. The mean age was 50, 7 cases being diagnosed after the menopause. The commonest symptom was metromenorrhagia (11 cases out of 16), but pain was more frequent in leiomyomas (9 out of 10). Treatment was above all surgical, total hysterectomy having the best prognosis (3 deaths out of 8 patients operated upon). Other methods (in particular radiotherapy) not being used immediately after surgery, they could not be studied. In terms of its difficult diagnosis and its high degree of malignancy (9 deaths out of 16), sarcoma must remain an argument in favour of total hysterectomy.

A 45-year-old Malay lady who presented with intermittent abdominal pain and a left hypochondrial mass was found to have a 10 x 8 x 5 cm duodenal tumour without local invasion at laparotomy. En bloc resection of the tumour with adequate margin of clearance was done and histopathological diagnosis of low grade leiomyosarcoma was made. Fourteen months later, she returned with multiple metastases in the liver and needed palliative chemotherapy for pain relief. Duodenal leiomyosarcomata are very rare tumour. Their prognostic indicators include biological grading, tumour size and presence of metastases. Recognition of its high malignant potential calls for close surveillance calls even after apparent curative surgery.

In this collective review, we have compiled all the reported cases of smooth muscle tumors of the rectum/anus in the world literature from 1959 to 1989. Our goal was to increase the data pool of smooth muscle tumors by adding these new data to that previously collected from 1881 to 1959. We increased the pool for leiomyomas from 89 to 148 and that for leiomyosarcomas from 54 to 215. By doing this, we hoped to make more accurate conclusions about smooth muscle tumors based on this increased data pool. Some interesting findings included three cases in small children that were found in our recent review: a 2-year-old with a leiomyoma and two small infants, aged 12 days and 36 days, with leiomyosarcomas. Again, the findings were probably consistent with an increased data pool. We were also able to find several more cases involving the anal region. We found the highest incidence of leiomyomas to have increased by a decade from the 40-49 year age group to the 50-59 year age group, while among leiomyosarcomas, there was about equal incidence among the 50-59 and 60-69 age groups. We doubt that these represent actual changes in the demographics, but rather that these latter findings are more accurate based on the greater quantity of cases available to us. As a further example, we found no appreciable sex difference; however, we did find more cases reported in females. From our increased data pool, we were able to find 16 more cases that were described as dumbbell-shaped, compared to one that was reported before 1959. Palpable mass, hemorrhage, and pain/discomfort continued as the most common symptoms reported at presentation. With regard to size, the majority of leiomyomas were found to be less than 5 cm in diameter, closely followed by those 5-9 cm. The majority of leiomyosarcomas were 5-9 centimeters at discovery. Most cases of leiomyoma were treated by excision, while most cases of leiomyosarcoma were treated by abdominoperineal resection, a finding consistent with old data. We hope that this paper thoroughly reviews pertinent information about leiomyomas and leiomyosarcomas of the rectum/anus and, in doing so, serves to refresh a few memories, stimulate others, and teach a few.

The clinical and pathological records of 22 patients treated for retroperitoneal sarcomas were retrospectively studied. The initial symptoms were pain and swelling of the abdomen in 11 patients. All tumours had a diameter of more than 10 cm. The pathological diagnosis was in 16 cases liposarcoma or leiomyosarcoma. Fourteen tumours were graded as high and eight as low. Sixteen of the 22 operated patients had complete resection of the tumour. Eleven patients had recurrence after five to 42 months, nine of them local recurrence and two distant metastases. Eleven patients needed repeated radical or palliative resections. Additional therapy (pre- or post-operative radiation or chemotherapy) was given to 11 patients. Radical resection of primary and recurrent tumours seems to give the best results in patients with retroperitoneal sarcomas but debulking of the tumour improves the quality of life in selected patients.
