Computerized tomography in malignant tumors.

Computerized tomography (CT) was used in the evaluation or follow-up of 89 patients with malignant tumors. Excellent correlation was found between the preoperative CT findings and those at surgical resection of the tumor in 52 patients. Ct scan was the only test demonstrating the tumor mass in 18% and was superior to other tests in 67% of patients. When used as a follow-up test to detect recurrence in 74 patients, it was the first test to reveal recurrence in 30.5% of 36 patients who developed recurrence. It was false negative in one patient, and gave rise to false positive interpretations in seven patients. Overall, the CT scan was superior to conventional radiologic techniques, but the latter are not replaced completely and remain essential in the pertinent anatomical situations.

Family physicians' beliefs about breast cancer screening by mammography.

A survey of 509 family physicians in New York State was conducted to assess opinions about mammography and use of mammography in screening asymptomatic women of different ages. Findings indicate that most family physicians believe that mammography is an effective procedure for detecting breast cancer in its early stages, but many do not utilize mammography as a screening procedure in their own practices. The major deterrents to the use of mammography in screening asymptomatic women relate to concerns about the safety and reliability of the procedure, the low probability of detecting breast cancer through screening, the patient's willingness to accept a recommendation to have a mammogram, and cost. The results from this study point out the need to better educate primary care physicians about the use of mammography in screening for breast cancer, especially in regard to its safety and reliability.

Phase II study--intra-arterial BCNU therapy for metastatic brain tumors.

Thirty-one patients with metastatic brain tumors (MBT) from lung cancer and ten patients with MBT from melanoma received BCNU, 100 mg/m2, every four weeks by intracarotid and/or vertebral artery infusion into each involved site. Twenty-five patients with lung cancer and all melanoma patients are currently evaluable. Twelve patients with lung cancer had complete and partial responses lasting from 1 to 14 months. Four of them with the histologic diagnosis of small cell carcinoma, one with large cell carcinoma and one with squamous cell carcinoma showed complete response. None of the patients with melanoma MBT experienced any response. All of the patients had periorbital erythralgia and/or occipital pain during the infusion. Four patients manifested mild focal seizures during the infusion or 6 to 24 hours after the treatment. Transient confusion with disorientation was observed in two patients 4 and 24 hours, respectively, after a BCNU infusion. Two patients developed reversible thrombocytopenia after the fifth course of the IA chemotherapy. Median survival of patients with MBT from lung carcinoma was 4 months, with two of them still alive at 10 and 14 months, respectively. Only one patients of the 25 with lung carcinoma died from MBT. Failure to control the primary disease resulted in the deaths of a vast majority of the patients.

Chemotherapy of nonirradiated malignant gliomas. Phase II: study of the combination of methyl-CCNU, vincristine, and procarbazine.

Twenty-eight adult patients with nonirradiated malignant gliomas of the brain were administered a combination of methyl-CCNU (130 mg/m2, p.o., day 1), vincristine (2 mg/m2, i.v., day 1) and procarbazine (100 mg/m2, p.o., days 2 to 15) (MVP), scheduled to be given at successive 6 week intervals. Nineteen (67.9%) were not responsive to MVP and 9 (32.1%) were. Of 16 who had previous partial resection of their tumors, 8 (50%) responded to MVP and 8 (50%) did not. Of 12 who had previous biopsy, only 1 (8.3%) responded. Overall 1-year survival rate for the 28 patients was 28.6%. Major side effects of MVP were leukopenia, thrombocytopenia, pulmonary emboli, and thrombophlebitis, detected mainly during the first 20 to 24 weeks of treatment.

The clinical value of lymphangiography: are the nodes surrounding the obturator nerve visualized?

Twenty-five patients subjected to pelvic node dissection for urologic malignancies underwent bilateral pedal lymphangiography preoperatively. Postoperatively, 50 samples of the nodes selectively removed from the regions surrounding the obturator nerve were radiographed. All 50 samples revealed the presence of radiopaque dye. The lymph nodes surrounding the obturator nerve represent the first point of lymphatic metastases in carcinoma of the prostate and the bladder. Their visualization by lymphangiography emphasizes the importance of such a diagnostic study for the correct clinical staging of these diseases. The lymphatic anatomy of the pelvis is reviewed and compared to the radiological findings in lymphangiography.

Spontaneous renal subcapsular hematoma renal angiography as a diagnostic aid.

Prior to the development of angiography, a definite diagnosis of spontaneous subcapsular renal hematomaa was not often made preoperatively. The classic triad of blood loss, pain, and mass on the affected side is seldom presented by the patient. The one constant finding on scout film is an enlarged renal shadow, presenting a problem in differential diagnosis. Chief among cause of subcapsular renal hemorrhage are trauma, tumor, infarct, arteritis, and bleeding diathises. Selective renal arteriography gives specific information about the renal vascular supply and the state of the renal parenchyma not available by other means. Diagnosis of subcapsular renal hematom is facilitated by this modality. A correct diagnosis of subcapsular renal hematoma may well spare an otherwise innocent kidney. A review of current literature was undertaken, and three documented cases of spontaneous subcapsular hematoma diagnosed prior to surgery and confirmed at surgery are presented.
