Trauma produced by amputation of a limb bearing the primary tumor influenced pulmonary metastases of the Carcinosarcoma of Walker 256 of the rat. This enhancement was present in 38% of the animals following the removal of a limb bearing the primary tumor; and in 29% of those in which the controlateral limb without tumor was amputated. A significant prolongation of the clotting time, an elevation of fibrinogen factor II and VII and a rapid consumption of factor VIII present soon after trauma may have been the parameter responsible for the increase of pulmonary metastases seen in this study.

Carcinosarcoma of the adult kidney is a very rare tumour and there are only a few well documented cases in the literature. In this report such a tumour is described from a 50-year-old white male, which progressed very rapidly with widespread metastases. Histologically, the tumour consisted of renal cell carcinoma and fibrosarcomatous components. The interesting features in this case were that both the carcinomatous and sarcomatous elements of the tumour exhibited metastases separately to various organs.

Carcinosarcoma accounted for 0.27% of nearly 3000 lung cancers examined in this department. All the patients were men aged between 44 and 62 years, and a majority of the tumours occurred in the left lung. Three patients died within six months of lung resection and in each case a postmortem examination was performed. In seven the carcinomatous component was a squamous-celled growth, and in one columnar-celled; the histology of the sarcomatous element varied. Carcinosarcomas form a distinct group of malignant lung tumours. In five cases sarcomatous transformation of the stroma had occurred and was considered to be the usual means by which the mixed type of growth arises. The other three were considered to be "collision" tumours. Carcinomatous metastases without sarcomatous change were seen in lymph nodes in three cases, and in three fatal cases sarcomatous tumour had recurred.

Unusual lung tumors are not simply pathological curiosities. They demonstrate features of major significance in diagnosis, treatment, and prognosis. Six of these tumours are discussed: (1) Carcinosarcoma is rarely found in the lung. The histogenis of the lesion is unclear and the prognosis is poor. (2) Only three cases of pleomorphic adenoma have previously been described. Differentiation from other "mixed tumours" of the lung is essential. (3) A rare case of bronchial adenoma producing ectopic ACTH is described. Early recognition of these polypeptide hormone-secreting tumours is stressed. (4) Oat cell carcinoma with the myasthenic (Eaton-Lambert) syndrome shows the clinical features which should permit early tumour diagnosis. The hazards of muscle relaxants must be recognized. (5) Prostatic carcinoma with endobronchial metastases is is discussed. The importance of localization of the primary tumour is emphasized. (6) An example of double primary carcinoma is presented. The rarity of this finding may be related to the poor prognosis of patients with bronchogenesis carcinoma.

A female patient is presented who had a large carcinosarcoma of the urinary bladder that became clinically manifest only 2 months before treatment. The initial treatment by transurethral resection was followed by radical cystectomy; 7 months postoperatively the patient died of local tumour recurrence with widespread metastases. Carcinosarcoma of the urinary bladder is a rare tumour with a poor prognosis. The majority of such tumours are not diagnosed until tumour growth is already far advanced. Owing to the small number of cases there is no clinically proven form of management. In contrast with superficial transitional cell carcinoma of the bladder, superficial carcinosarcoma of the bladder has always invaded the lamina propria, since in addition to the carcinomatous degeneration of the mucosa, sarcomatous degeneration of the underlying submucosal stroma is also present. Any local surgical treatment, such as TUR or partial cystectomy, involves the risk of incomplete tumor removal, because the sarcomatous elements typically invade the submucosa while the overlying mucosa remains intact. Therefore, radical cystectomy appears to be the treatment of choice for both superficial and invasive carcinosarcoma of the urinary bladder.

Carcinosarcoma of the prostate is a biphasic tumor containing adenocarcinoma (ACA) and recognizable sarcomatous components. It is a rare neoplasm with only 12 previous reported cases. We describe three additional cases arising between 4 and 6 years after initial diagnosis of prostatic ACA. Two patients were initially treated by prostatectomy, pelvic external beam radiotherapy, and hormonal manipulation. The third patient was treated by pelvic lymphadenectomy and 125I implants. After the development of the sarcomatous component, the first two are still alive with distant metastases and residual pelvic disease at 9 and 17 months. The third patient died with disease 7 months after diagnosis. Histologically, prostatic ACA was recognized in all three cases, as well as a neoplastic mesenchymal component that appeared later. Foci of osteosarcomatous, chondrosarcomatous, and myosarcomatous differentiation were recognized in two of the three cases. Based on the chronologic and the histologic evolution of the neoplasm, we favor sarcomatoid transformation of the ACA as the most likely histogenesis. It appears that radiotherapy and hormonal therapy may be important in the development of at least some of these tumors.

Carcinosarcoma of the lung is a rare malignancy consisting of both epithelial and mesenchymal components. Although metastatic disease is common, metastatic disease to the small intestine is rare and has been reported only once in the literature. An unusual case of pulmonary carcinosarcoma with metastasis to the small bowel is presented. At the time of laparoscopic exploration, a 4 x 4 cm mass was seen in the jejunum involving the adjacent mesentery. The affected small bowel and mesentery were resected laparoscopically and bowel continuity was restored through an entirely intracorporeal technique. Laparoscopic small bowel resection can be performed safely in the setting of malignant disease and imparts many of the benefits of minimally invasive surgery.

Carcinosarcoma is a rare tumor of the uterus with a poor prognosis, even when identified and treated at an early stage. The purpose of this study was to identify and analyze prognostic pathologic features and treatment outcomes in patient with stages I and II carcinosarcoma of the uterus. Patients with carcinosarcoma of the uterus who received primary surgical treatment between 1984 and 2004 were identified through an institutional tumor registry. Inclusion criteria were clinical stage I/II disease following hysterectomy and selective pelvic and para-aortic lymph node sampling. Regression analysis was used to determine risk factors for recurrence and survival. Disease-free and overall survival were then determined using Kaplan-Meier analysis. Forty-seven patients with stages I and II carcinosarcoma of the uterus were identified. Age, heterologous or homologous histology, and type of adjuvant treatment were not associated with recurrence or survival. Depth of myometrial invasion was found to correlate to disease-free survival but not overall survival. The number of lymph nodes collected correlated to risk of recurrence and survival. Disease-free and overall survival were greater in patients with higher lymph node count. We conclude that the number of lymph nodes collected was the only risk factor that was found to be correlated to recurrence and survival in patients with early-stage carcinosarcoma. These results support mounting evidence that lymphadenectomy is crucial in patients with carcinomas of the uterus in order to discover occult metastatic disease and potentially provide patients with a therapeutic benefit.

Carcinosarcoma is a malignancy that occurs very rarely in the renal pelvis, and only a very limited number of cases has been documented. These tumors are composed of both malignant mesenchymal and epithelial elements. Unlike the cases described so far, this carcinosarcoma of the renal pelvis was characterized by quick recurrence, following complete surgical resection. Carcinosarcomas of the renal pelvis are known to be rapid in progression and associated with a poor prognosis. They usually metastasize soon after surgery, but very little information is available on the histologic types that characterize the recurrent tumors. We presented a histologically proven case of renal carcinosarcoma extending from renal pelvis. Convalescence was uneventful, and fifteen months after the operation, he is alive with no recurrence or metastasis. If a rapidly growing tumor is detected that seems to originate from the kidney with extension to ureter and bladder, carcinosarcoma should be included in the differential diagnosis.

Carcinosarcoma of the colon is rare. Seventeen cases have been reported in the English literature. Most cases occurred in the left side of the colon. Indeed, there is only one reported case of cecal carcinosarcoma. Carcinosarcoma has a tendency to distantly metastasize and shows dismal prognosis. We report a case of carcinosarcoma in the cecum and review the literature describing colonic carcinosarcoma.
