There were 100 patients with clinically localized prostatic carcinoma staged surgically for the evaluation of lymph node metastases. By correlating the incidence of lymph node metastasis with the level of serum acid phosphatase, and the stage and grade of the primary tumor, it was possible to identify 1 group of patients with less than 8 per cent incidence of lymph node metastases and another group with more than 92 per cent incidence of nodal involvement. It is in these 2 groups of patients that pelvic lymphadenectomy for the staging of prostatic carcinoma may not be necessary.

The estrogen receptor (ER) level in carcinoma of the breast is a useful predictor of response to hormonal therapy. Metastatic disease may not have the same level of ER as the primary. In a series of 37 patients who had simultaneous ER determination in both primary neoplasm and regional nodal metastasis there was 81% agreement. The true ER character of the tumor would have been missed in seven patients if only the primary tumor had been sampled. The possible reasons for this discrepancy are discussed. We feel that the nodal metastatic deposit may reflect the true nature of the ER status because it represents a purer concentration of tumor cells as well as representing the aggressive element of the tumor.

The results of treatment of 199 patients referred to the Royal Marsden Hospital with testiclar seminoma from 1963 to 1975 are described. Of 190 previously untreated patients 16 (8.4%) have died of seminoma, 3 (1.5%) of teratoma and 9 (4.9%) of intercurrent disease. Of 121 Stage I patients the only death was due to a second testicular tumour. In orchiectomy and volume of abdominal node metastases. This was not, however, prognostically significant. Death from seminoma occurred in 6 out of 38 patients (15.8%) with nodal metastases less than or equal to 5 cm in diameter and 3 out of 16 patients (18.7%) with metastases greater than 5 cm in diameter; 2 of 8 Stage III patients died of seminoma. Thus radiation controlled nodal metastases in more than 80% of Stage I, II and III patients. In Stage IV patients and patients referred with disease relapse, 12 out of 16 patients died of seminoma. Chemotherapy experience is briefly reviewed. Cyclophosphamide as a single agent has produced a 50% response rate. There is no evidence to suggest a radiation-related increase in mortality from the group of long-term tumour-free survivors.

Eight cases of a rare, distinctive variant of infiltrating mammary carcinoma featuring benign multinucleated osteoclast-like giant cells are reported. The multinucleated osteoclast-like giant cells are reported. The multinucleated giant cells were associated with ductal carcinoma in five cases and with infiltrating lobular carcinoma in three cases. Although three patients had lymph nodal metastases in level one, none of the nodal metastases contained giant cells. From the limited follow-up data of this report, it seems likely that the prognosis for patients who have this type of adenocarcinoma is not especially favorable. The observation that the giant cells generally occurred in areas of prominent angiogenesis suggests that the angiogenesis may be induced by some chemical substance produced by the tumor cells. Biochemical and immunologic investigations may eventually provide an explanation for this unusual morphologic manifestation of host reaction to mammary carcinoma.

Twenty patients with well-differentiated thyroid carcinoma, 20 yr of age or younger have been treated at Vanderbilt University Hospital. The young patient with thyroid carcinoma frequently presents with far-advanced disease but enjoys an improved survival. Preoperative scintiscanning is useful in the evaluation of patients with childhood thyroid carcinoma. A new noninvasive scan is described and appears to be promising in the preoperative differentiation between benign and malignant thyroid lesions in children and young adults. There is a high instance of nodal metastases, but long-term follow-up would indicate that lobectomy and modified neck dissection are sufficient for most patients. However, total thyroidectomy can be performed safely in those patients with disease in both lobes. Additionalally, frozen section diagnoses were found to be helpful in diagnosing and staging thyroid carcinoma.

Lymph node metastasis was evaluated angiographically in 151 patients with gastric cancer. In 20% of the patients with nodal metastases, abnormally staining masses were demonstrated by angiography. Superselective angiography is useful in confirming the presence of lymph node involvement.

The Evanston Hospital maintains an Irradiated Thyroid Evaluation Clinic that has evaluated 695 patients since 1975. One hundred fourteen patients were retrospectively analyzed, and an attempt was made to correlate the preoperative physical examination with the pathologic specimen after thyroidectomy. There was no statistically significant difference between the incidence of carcinoma in glands containing a single nodule (23 per cent) and in multinodular glands. Postirradiation thyroiditis complicated the physical description of glands preoperatively. The categorization of physical findings served only to identify persistent thyroid abnormalities, which must be explored surgically. The overall incidence of carcinoma in the 114 available cases was 34 per cent, with nodal metastases in 18 per cent of the patients with carcinoma.

Twenty-five patients with tubular carcinoma of the breast were reviewed. All of the lesions were small, averaging 0.9 cm in diameter, and none exceeded 2.0 cm in diameter. Regardless of treatment, the prognosis proved favorable. Only three of the patients manifested axillary lymph nodal metastases, and none died of recurrent or metastatic neoplasm. These neoplasms frequently were associated with intraductal carcinoma and, to a lesser extent, with lobular carcinoma in situ. It is concluded that tubular carcinoma represents a slow-growing expression of invasive mammary carcinoma; nevertheless, it is likely that, if inadequately treated, these lesions will evolve into more common patterns of invasive carcinoma.

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.

Forty three children with testicular tumors have been presented. Eighty per cent of these tumors were malignant, and 60 per cent occurred in children less than two and one half years of age. Twenty of the 24 malignant germinal tumors were embryonal cell carcinomas. The mean age of the patients at presentation of these tumors was 18 months. Nine patients underwent orchiectomy alone, and five of these have died. Eleven received combined therapy, and all have survived. We currently recommend radical orchiectomy and extended unilateral retroperitoneal lymphadenectomy. If examination of the nodes reveals evidence of metastases, a bilateral dissection is done. Radiotherapy is given only in the presence of nodal metastases. Adjuvant chemotherapy with vincristine, actinomycin D, and Cytoxan is given for two years to all patients with malginant nonseminomatous germ cell tumors or sarcomas.
