Needle biopsy of endothoracic neoformations: a five-year experience.

We dwell upon the importance of percutaneous biopsy in the diagnosis of endothoracic masses, comparing the results of the cutting needles to those of the fine needle aspiration biopsy. We began utilizing the Vim-Silverman needle with good results (73.7% diagnoses) and a small number of complications, only 1 of which needed treatment, but in the light of the severe and lethal complications described in the literature, we came to prefer the use of the fine needle aspiration technique, which provided good results, too, (74% diagnoses) and enlarged the diagnostic range of the percutaneous biopsy of the lung in cases of deep, or mediastinal masses. We also hold that the use of cutting needles should not be given up: in fact when a technically good smear from an aspiration biopsy does not allow a diagnosis, we usually repeat the biopsy using a cutting needle, if there is no contraindication.

Lymphangiography in patients with ovarian epithelial cancer: an evaluation of 289 consecutive cases.

From January, 1973, to June, 1976, 226 patients with palpable ovarian masses were evaluated preoperatively by lymphography. Histology showed 166 cases of malignant epithelial tumors, 26 benign tumors, and 34 malignant special tumors (not included in this report). Furthermore, the group of patients included 99 recurrences of ovarian epithelial cancer and 24 patients who underwent restaging diagnostic procedures without clinical evidence of disease. Lymphography was negative in all patients with benign tumors. In the 289 cases of epithelial cancer, lymphangiography gave evidence of nodal metastases in 88 (30%). When the histological subtype was considered, the highest incidence of metastases was in undifferentiated carcinoma (50%) and the lowest, in mesonephroid carcinoma (14%). According to the stage before lymphography, nodal metastases were found in 8% of Stage I, 0% of Stage II, 29% of Stage III, and 53% of Stage IV cases. The incidence of metastases was 46% in patients studied for recurrent disease and 17% in patients studied for restaging. Fifty-four percent of patients had metastases only in the pelvic nodes and 18% only in the para-aortic chains; in 28% both chains were involved simultaneously. Bilateral involvement was found in 63% of the positive cases. Retroperitoneal node biopsies were performed in 68 patients (36%). The radiologic/histologic correlation was 100% in the lymphangiographically positive cases; 81% in the negative cases, with nine false-negative reports; and 87% in all cases.
