Phase II evaluation of didemnin B in advanced adenocarcinoma of the kidney. A Southwest Oncology Group study.

The Southwest Oncology Group studied the response rate and toxicity of didemnin B (3.47 mg/m2 i.v. q 28 days) in patients with advanced renal cell carcinoma. There were no responses in 22 response evaluable patients. Toxicity was significant with 10 patients having grade 3 or 4 toxicity. Toxicity seen included nausea and vomiting, exacerbation of coronary artery disease, hyperglycemia, anorexia, diarrhea and hepatitis. Didemnin B was toxic but inactive in patients with renal cell treated at this dose.

Gastric carcinoma after gastrojejunostomy for benign disease: radiographic findings.

Although it is not well recognized in the radiologic literature, gastric carcinoma has been reported to occur as a late complication of gastrojejunostomy for benign disease, even in the absence of partial gastrectomy. We present the radiographic findings in two patients with this complication and review clinical and experimental data supporting the role of gastrojejunostomy in the subsequent development of gastric carcinoma.

Treatment of stages B3 and C seminoma with chemotherapy followed by irradiation therapy. Southwest Oncology Group Study.

Beginning in 1981, 28 patients with advanced seminoma were treated with combination chemotherapy followed by irradiation to evaluate the possibility of improved survival using both modalities. The treatment protocol consisted of two courses of vincristine, actinomycin-D, and cyclophosphamide followed by reassessment. Those initially presenting with Stage B3 disease who achieved a complete response to two cycles of chemotherapy then underwent irradiation. All others were given a third course of chemotherapy before undergoing irradiation. The pre-radiation portion of this protocol produced a complete response rate of only 25 percent, substantially less than other, more recent, protocols. Radiation therapy produced a complete response in 69 percent of those who did not achieve a complete response from chemotherapy, increasing the complete response rate from 25 percent to 64 percent. Given this response rate to radiation therapy and the difficulty of dissection and associated morbidity with the surgical excision of postchemotherapy residual masses, the best option at this time may be observation with salvage chemotherapy and/or radiation reserved for those with disease progression.

Radiographic appearance of bullet tracks in the lung.

Penetrating missile or bullet wounds to the lung result in a number of abnormalities visible on chest radiographs. One finding that is unique to pulmonary parenchyma is the bullet track, which occurs along the course of a bullet as it traverses the lung. A bullet track may occur in the lung because of this organ's low specific gravity and high elasticity. In other tissues, such as liver and brain, that have higher specific gravities and lower elastic content, bullet tracks are rarely, if ever, noted because widespread destruction usually occurs. Bullet tracks may have a delayed appearance on chest radiographs, and thus may cause confusion in interpretation if a history of injury is not elicited. With the increase in violet confrontations in the United States, it is more and more likely that radiologists will be asked to interpret chest radiographs of patients who have had penetrating bullet injuries to the thorax. In this pictorial essay, we illustrate the appearance of bullet tracks in lung on chest radiographs.

Low-pressure balloon angioplasty of an occluded portacaval shunt.

Safe angioplasty of a portacaval shunt requires particular knowledge of the tissue characteristics of an anastomosis and the behavior of a balloon during inflation. The nature and true diameter of a portacaval shunt anastomosis are more difficult to evaluate than those of a peripheral arterial lesion, and complications are potentially more hazardous than those related to peripheral arterial angioplasty. We suggest that in some instances low pressure and incomplete balloon inflation are all that is necessary to yield safe and satisfactory results.

CT evaluation of the abdominal wall.

Computed tomography (CT) is a useful method for evaluating the abdominal wall. Pathology includes hernia, hematoma, infection and inflammation, tumor, and post-traumatic, post-operative, and miscellaneous conditions. The CT findings of these various abnormalities are presented.

A phase II multi-institutional trial of low-dose N-(phosphonacetyl)-L-aspartate and high-dose 5-fluorouracil as a short-term infusion in the treatment of adenocarcinoma of the pancreas. A Southwest Oncology Group study.

Adenocarcinoma of the pancreas is a highly lethal malignancy and chemotherapy has had little impact on the natural history of this disease. PALA, used to potentiate 5-fluorouracil (5-FU), has been shown to have synergy in vivo and in vitro. Twenty-seven patients were treated with an intravenous push dose of PALA (250 mg/m2) followed 24 hours later with a 24-hour infusion of 5-FU (2600 mg/m2). This regimen was repeated weekly. There was one partial response of 21 eligible patients with an estimated response rate of 5%. Toxicity was severe with one toxic death and four patients experiencing Grade 4 toxicity. 5-Fluorouracil and PALA, given in the schedule described, do not appear to be effective against adenocarcinoma of the pancreas.

Phase II evaluation of amonafide in renal cell carcinoma. A Southwest Oncology Group study.

Twenty four patients with advanced renal cell carcinoma were treated in a phase II trial with amonafide 300-450 mg/m2/day on days 1-5 every 21 days. There were no responders, 6 patients had stable disease, 14 experienced progressive disease and 4 were assumed to be non-responders as no evaluation was performed. There were no fatal toxicities although 8 patients had grade 3 or 4 granulocytopenia, 1 patient had grade 4 thrombocytopenia. Other toxicities included grade 3 diarrhea in 1 patient, grade 3 myopathy in 1 patient, severe nausea and vomiting in 1 patient and a facial rash, possibly a hypersensitivity reaction, in 1 patient. The median survival is 7.5 months. At this dosage and schedule, there is no evidence that amonafide has meaningful anti-tumor activity in patients with advanced renal cell carcinoma.

Extrusion of PEG tube from the stomach with fistula formation: an unusual complication of percutaneous endoscopic gastrostomy.

Percutaneous endoscopic gastrostomy (PEG) has become an accepted technique for providing long-term enteral feeding. We report two cases of extrusion of the PEG tube into a short fistulous tract that communicates with the stomach. Although this unusual complication led to difficulty with tube feedings, both patients were asymptomatic, and, in one case, it was possible to reposition another catheter in the stomach via the fistula.

A phase II trial of recombinant tumor necrosis factor in patients with adenocarcinoma of the pancreas: a Southwest Oncology Group study.

Twenty-two evaluable patients with advanced adenocarcinoma of the pancreas, but without prior chemotherapy or immunotherapy, received recombinant tumor necrosis factor (rTNF). rTNF was given as an intravenous infusion over 30 min daily x 5, every 14 days, at a starting dose of 150 micrograms/m2/day. Toxicities included fevers/rigors, nausea/vomiting/anorexia, flu-like symptoms, hypotension, hyperglycemia, anemia, coagulopathy, hepatotoxicity, and hypertriglyceridemia. Laboratory evidence of disseminated intravascular coagulopathy occurred in 11 patients, with only 3 of these patients having clinical manifestations. Two patients suffered from pulmonary emboli. The high incidence of coagulopathy was felt to be, at least in part, disease related. No objective responses were observed with a 95% confidence interval of 0-15%.

Idiopathic colonic perforation in the neonate.

We describe a premature infant in whom spontaneous perforation of the colon was initially detected on routine abdominal films. There was no clinical evidence of necrotizing enterocolitis, peritonitis, or bowel obstruction. Surgical and pathologic findings confirmed the diagnosis of idiopathic bowel perforation. Since spontaneous gastrointestinal perforation in the neonate is often difficult to diagnose clinically, radiographic evaluation may allow earlier diagnosis and prompt surgical treatment of this life-threatening condition.
