99mTc-methylene diphosphonate (99mTc-MDP) bone scans in 80 patients, 30-80 years old (average, 62 years old) with uterine cancer who received high doses of radiation (10-60 Gy; average, 46 Gy) were reviewed retrospectively to evaluate the frequency of pelvic insufficiency fractures caused by radiotherapy and to study the appearance of the fractures on bone scans. Bone scans in 29 of 80 patients showed abnormalities in the pelvis: insufficiency fractures were identified in 27 patients (34%) and osseous metastases were found in two patients (3%). The fractures and metastases were diagnosed by CT and were confirmed by observing the patients' clinical courses. Fractures were identified in 27 (39%) of 69 postmenopausal women and in none of 11 premenopausal patients (p greater than .05). Fractures were found in 21 (84%) of 25 patients who had pelvic pain and in six (11%) of 55 patients who were asymptomatic (p greater than .001). Scintigrams in patients with fractures showed more than one fracture in most patients (85%), and fractures were often symmetric (67%). Scintigrams in two patients with osseous metastases showed increased activity in an iliac wing that was outside the radiation field. Our results suggest that a marked increase in insufficiency fractures occurs after radiation therapy, especially in postmenopausal patients. A symmetric area of increased uptake of radionuclide is a characteristic scintigraphic appearance of an insufficiency fracture.

The best treatment of advanced rectal cancer remains uncertain. The aim of this study was to determine the outcome after palliative procedures in patients with advanced rectal cancer. One hundred and three patients treated over a seven-year period were identified, including 30 with local invasion, 18 with local metastases, and 55 with distant metastases. Patients were grouped into two groups: those who underwent palliative resection (68) and those who were treated without rectal resection (55). The nonresected group included patients who underwent diverting colostomies (28) and those who received multimodality therapy without surgery (7). The average age of all patients was 63.1 years. Patients in the nonresected group had more distant disease (68 percent) than the resected group (46 percent). Significant pelvic pain was a more common problem in the nonresected group (15 percent) than in the resected group (4 percent). Similarly, pelvic sepsis was more common in the nonresected group (14 percent) than in the resected group (9 percent). Postoperative mortality was 4.3 percent after palliative resection and 3.8 percent after diverting colostomy. Survival of the resected group at one year was 65 percent and at two years 20 percent. Survival of the nonresected group at one year was 20 percent and at two years 0 percent. Survival in the resected group was significantly (P less than .01) better than the nonresected group but probably can be attributed to the more extensive disease generally present in the patients who did not undergo resection. These results suggest that patients with advanced rectal cancers should undergo palliative resection whenever possible because resection decreases pelvic complications and may improve quality of life.

We describe 16 cases of intravenous leiomyomatosis of the uterus with unusual histologic features. Most of the patients, who ranged in age from 28 to 76 years (median, 42 years), presented with abnormal uterine bleeding or pelvic pain. On pelvic examination, they had an enlarged uterus. Extension of tumor into the broad ligament was noted at operation in six patients; it was documented on pathologic examination in an additional three cases. Gross examination disclosed enlargement of the uterus by solitary or multiple masses; wormlike plugs of tumor within myometrial veins were noted on initial examination in only five cases. Histologic examination in each case revealed proliferations of benign-appearing smooth muscle within myometrial vessels, at least some of which were large veins. The tumors differed from typical intravenous leiomyomatosis (IVL). They were classified as cellular IVL (six cases), epithelioid IVL (four cases), IVL with bizarre nuclei (two cases), intravenous lipoleiomyomatosis (two cases), myxoid IVL (one case), and IVL with an endometrial component (one case). Of 13 patients with follow-up information, 11 are alive with no evidence of disease or have died of unrelated causes at postoperative intervals of 0.5 to 19 years. One patient underwent resection of pelvic recurrent tumor 2 years postoperatively and was alive with no evidence of disease 2 years later. Another patient had pulmonary metastases 9 years postoperatively, but was alive with stable disease after an additional 6 years. This analysis indicates that most of the histologic variants of benign uterine leiomyoma can exhibit the intravascular growth pattern of IVL. These variants of IVL, except for their cellular composition, resemble typical IVL in both their clinical and pathological features. They should be distinguished from other tumors, particularly endometrial stromal sarcoma and leiomyosarcoma, which differ in their behavior and management.

Uterine carcinosarcoma is a rare and rapidly fatal malignancy. The records of 49 patients with carcinosarcoma were studied; from these studies emerged a symptom complex of vaginal bleeding and abdominal or pelvic pain. Eleven patients had been previously irradiated at an average of 16.4 years before they developed uterine carcinosarcoma. Celiotomies revealed more extensive tumor than could be determined by pelvic examination under anesthesia. The majority of the patients died from local recurrence in the pelvis rather than from distant metastases. The overall 5-year survival was 6%. Celiotomies are recommended to stage carcinosarcomas and guide treatment decisions.

The authors report a case of endometrial stromal sarcoma which was detected by endometrial cytology. The tumour originates either in the stroma of the endometrium or in foci of myometrial adenomyosis. It occurs most frequently in patients who are more than 60 years of age. It appears as an intra-uterine polypoid mass and causes bleeding and pelvic pain. Its incidence is difficult to establish. Endometrial cytology is highly suggestive of stromal sarcoma when smears harbour numerous atypical sarcomatous cells mixed with regular endometrial cells. Biopsies of the endometrium show decidua-like arrangements of malignant cells. Stromal sarcoma constitutes the homologous form of mesenchymal tumours of the uterus. The prognosis depends on whether local recurrences occur and on the sites of metastases in which the sarcomatous component seems to be latent with lesions that resemble adenocarcinomata . The five years salvage rate is approximately 26 to 28%. Treatment is surgical with or without irradiation.

A clinicopathologic study of 15 cases of primary adenocarcinoma of the uterine tube occurring over a 12-year period is presented. The mean age of the patients was 54.8 years. Predominant symptoms were abnormal bleeding, abnormal vaginal discharge, and pelvic pain. Abnormal vaginal cytology was noted in two instances (13%). A pelvis mass was detected in two thirds of patients. The neoplasm was bilateral in three instances (20%). Lymph nodes were involved in eight cases (53%), and metastatic spread to the para-aortic nodes was present in five (33%). The most common primary treatment was total abdominal hysterectomy and bilateral salpingo-oophorectomy. Various combinations of adjuvant radiation therapy and chemotherapy were also employed. Six patients (40%) are alive without evidence of recurrent cancer. It is concluded that lymphatic spread, especially to the para-aortic nodes, is a major pattern of disseminaton for adenocarcinoma of the uterine tube. The presence of tumor in capillary-like spaces bears a strong relationship to lymph node metastases, and the para-aortic nodes are a frequent site of involvement even when the disease is apparently limited to the tube.

We report the clinical and pathologic features of an adenoid cystic carcinoma of the submandibular gland that metastasized to the ovaries 10 years after initial presentation. A 30-year-old woman underwent excision of a right submandibular adenoid cystic carcinoma followed by regional external beam radiation therapy. Three years later, she underwent extended hepatic resection and localized radiotherapy to the hepatic region for metastatic disease. The patient was without evidence of disease for 7 years when she developed pelvic pain and a pelvic mass was found. A solid and cystic 10-cm left ovarian mass and a single metastatic tumor nodule involving the right ovary were excised via the laparoscope. Histologically, the tumor was identical to the patient's initial salivary gland neoplasm. The neoplastic cells were CAM 5.2 positive, S100 positive, muscle-specific actin positive, and smooth muscle actin positive. Ultrastructurally, characteristic pseudocysts (pseudolumina) with abundant basal lamina and true glandular lumina lined by short microvilli were present. Other than a single anecdotal account of a parotid gland adenoid cystic carcinoma, this case represents the first documented report of an adenoid cystic carcinoma of salivary gland origin that was associated with symptomatic ovarian metastases. This case demonstrates that the ovary is a potential site for metastatic disease many years following the diagnosis and treatment for a primary neoplasm however uncommon or remote the site of origin. Since metastatic adenoid cystic carcinoma can rarely present as an ovarian mass, a clinical history of this neoplasm should be heavily weighed in the differential diagnosis of any unusual ovarian tumor with a predominant cribriform, trabecular, or tubular pattern.

The incidence, presentation, and macroscopic and histological features of secondary solid neoplasms of the prostate gland are described with reference to their differential diagnoses. A continuous series of autopsy and surgical cases from the Royal London Hospital from 1907 to the present yielded a total of 51 secondary neoplasms involving the prostate: 24 at post-mortem examination and 27 surgical specimens. The histology of these specimens was re-examined. In 34 cases, tumour reached the prostate by direct spread: 29 from the bladder and 5 from the rectum. The most common primary sites of metastases to the prostate were lung (eight cases) and pancreas (two cases). There were isolated examples of metastases from the bladder, rectum, skin (malignant melanoma), breast, eye (malignant melanoma), adrenal cortex and gallbladder. Secondary neoplasms represented 2.1% of all neoplasms in surgical specimens, a similar proportion of the total number of malignant solid neoplasms as secondary tumours at other sites in the genitourinary tract. The patients were usually symptomatic, presenting with prostatism, haematuria or pelvic pain, almost always in those with widely disseminated disease.

Metastases to the sacroiliac joint region can be a source of significant pain in many patients who are terminally ill. Six patients with metastatic lesions in the sacroiliac region who presented with significant posterior pelvic pain were treated with computed tomography-guided insertion of iliosacral screws. All patients reported excellent pain control in the early postoperative period. Computed tomography-guided insertion of iliosacral screws in an area of relatively preserved bone stock provides good purchase of the screws. It is a safe percutaneous procedure and it helps alleviate pain in patients with sacroiliac metastases.

Positron emissions tomography/computed tomography (PET/CT) scan has been used in many types of cancer to characterize the extent of disease as well as to identify the presence of metastases. However, the utility of PET/CT in patients with both cancer and osteoporosis is less well delineated. In this case, a patient with known metastatic colorectal cancer who was investigated by many forms of conventional imaging for back and pelvic pain was found to have osteoporotic fractures using PET/CT. At the same time malignant disease was excluded.
