Ewing's sarcoma: an approach to radiological diagnosis.

All the pertinent radiographs of 83 patients with histologically proven Ewing's sarcoma were reviewed. Forty-nine patients were in the pediatric age group, and 34 were adults. The mean age, the symptoms and time from symptoms to diagnosis were evaluated in the 2 groups. The site of primary involvement was in 54% the long bones, 35% the flat bones, 8% the small bones and 3% extraosseous. For the primary site we considered the diagnostic results of the standard radiographic investigations and in some cases the usefulness of angiography, xeroradiography and telethermography. At presentation we also evaluated the possible diffusion of the disease with standard radiographic surveys (chest and skeletal, including limbs) and with foot lymphography in selected cases. In this way, 57 patients (69%) were considered to have localized disease. In this group, we also considered the value of the periodic radiographic follow-up, which enabled us to disclose the appearance of metastases (chest 64%, bone 54%, lymph nodes 11%) in 28 cases (49%). Finally, we made a comparison of the different radiologic and epidemiologic findings between children and adults.

Clinical classification and survival in chronic lymphocyte leukemia.

Sixty-one consecutive patients with chronic lymphocytic leukemia (CLL) treated at the Istituto Nazionale Tumori of Milan from September 1962 to August 1976 were classified according to the staging system of Rai et al. (16). Analysis of this series showed the following median survival (in months) from diagnosis: stage 0-I, 73; stage II, 44; stage III-IV, 32. In 11 patients without peripheral palpable adenopathies, the lymphangiogram showed abnormal retroperitoneal lymph nodes. Therefore, the initial stage was changed from 0 to I in 5 cases. The median survival for the entire series was 50 months. Patients with "indolent" disease had a median survival of 52 months, while in patients with "active" CLL, the median survival was 32 months. Both sex and age were shown to be poor predictors of survival. Increased duration of survival was observed in patients with less compared to those with more than 30,000 lymphocytes/mm3 (66 versus 41 months). The method of staging proposed by Rai et al. and utilized to classify this series at the time of diagnosis was confirmed to be a reliable predictor for survival.

Restatement of lymphography in childhood: experience with 413 consecutive patients in ten years.

From January 1969 to June 1978, 413 children under 15 years of age underwent lymphography at the Istituto Nazionale Tumori of Milan. Successful lymphatic cannulation was accomplished in 97.7% (769/787) of the sites where it was attempted. No major or permanent complications were encountered. In those children undergoing biopsy of opacified lymph nodes, the lymphographic-histologic correlation was 94.5% (104/110). This study has shown that lymphography in childhood can be as readily performed as in the adult and that its diagnostic accuracy is acceptable. As in adults, it is useful in treatment planning, evaluating results of therapy, and detecting a recurrent tumor.

[Lymphographic examinations in the pediatric age: review of 413 cases].

From January 1969-June 1978, 413 children less than 15 years of age underwent lymphography at the National Cancer Institute, Milan. Successful lymphatic cannulation was accomplished in 97.7% (769/787) of the sites where it was attempted. No major or permanent complications were encountered. In those children undergoing biopsy of opacified lymph nodes, lymphographic-histologic correlation was 94.5% (104/110).

[Neuroblastoma: radiological findings in 124 cases (author's transl)].

All the pertinent radiographs of 124 patients with histologically proven neuroblastoma were evaluated. The radiological features of the primary tumor and radiographic characteristics of metastases were also analyzed. Finally the value of radiological investigations to define the diffusion of the disease in comparison with laboratory and clinical findings were considered.

Malignant histiocytosis: a clinicopathologic study of 18 consecutive cases.

The clinical records and histologic material of 18 consecutive patients with malignant histiocytosis were reviewed. The age of the patients ranged from 20 months to 72 years (median 35 years). There were 14 males and 4 females (3.5:1). Lymph node and liver enlargement, fever, and skin nodules were the most common physical findings; and leukocytosis was frequently the most abnormal laboratory test. Seven of 18 patients died, and their survival ranged from 1 to 15 months (median 8 months) after histopathologic diagnosis. The histologic findings on lymph nodes, spleen, liver, bone marrow, and skin were investigated with special reference to both the cellular composition and the pattern of lymph node involvement. Vascular invasion of small perinodal vessels was observed in 4 fatal cases. The absence of capsular invasion and the lack of cohesiveness among atypical proliferating histiocytes of malignant histiocytosis appeared to be inconstant. Sequential lymph node biopsies revealed in later stages the extension of the histiocytic proliferation from the sinuses into the cords and the complete obliteration of the nodal structures. The radiologic investigations yielded numerous pathologic findings that were consistent with the dissemination of the disease. Complete response to initial treatment was achieved in patients that were treated with radiotherapy and/or chemotherapy. Complete response with chemotherapy was achieved only when the treatment included adriamycin. The histologic and clinical features of the present series provide future evidence for the recognition of malignant histiocytosis as a distinct clinical and pathologic entity.

The lymphatic spread of ovarian germinal and stromal tumors.

This paper reports the results of lymphography in germinal and stromal tumors of the ovary. The group of patients is made up of 30 cases of germ cell tumors (70% dysgerminomas) and 29 cases of stromal tumors (62% granulosa cell tumors). The overall incidence of metastases was 29%; 37% in germ cell and 21% in stromal tumors. There was bilateral involvement in 41% of the patients with metastases. The para-aortic region alone was involved in 23%, the iliac alone in 18% and both the regions were simultaneously involved in 59%. In 17/30 operated patients (57%) retroperitoneal node biopsies were performed and diagnostic accuracy was 9/10 in the radiographically positive and 6/7 in the negative cases.

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.

The radiologic diagnosis of malignant tumors of the salivary glands.

Radiologic investigation of possible salivary gland malignancy may answer in part questions concerning the lesion under study. Is it an invasive tumor, as evidenced by tissue destruction? Is the tumor intrinsic or extrinsic in origin to the salivary gland? Does the tumor extend into the deep portion of the salivary gland or beyond it into surrounding soft tissues? Sialography plays the major diagnostic role in consideration of the radiologic diagnosis of malignant tumors of the salivary glands. However, certain advanced radiologic modalities such as salivary gland scanning with sodium pertechnetate or 67Gallium citrate, as well as cervical ultrasound and computed tomography, may prove useful. This paper attempts to provide some answers to these questions.

Combination chemotherapy as an adjuvant treatment in operable breast cancer.

Prolonged cyclic combination chemotherapy with cyclophosphamide, methotrexate and fluorouracil was evaluated as adjuvant treatment to radical mastectomy in primary breast cancer with positive axillary lymph nodes. After 27 months of study, treatment occurred in 24 per cent of 179 control patients and in 5.3 per cent of 207 women given combination chemotherapy (P less than 10(-6)), the advantage appearing statistically significant in all subgroups of patients. Patients with four or more positive axillary nodes had a higher per cent of relapses than those with fewer nodes. The initial new clinical manifestations occurred in distant sites in 81.5 per cent of relapsed patients. Long-term chemotherapy produced an acceptable toxicity, thus allowing the administration of a high percentage of drug dosage. These results should be considered with caution, since, at present, the effect of this therapy on survival and possible long-term side effects remain unknown.

Lymphographic evaluation of 250 patients with malignant melanoma.

Foot lymphography was performed in a selected group of 250 patients with malignant melanoma, with different sites of origin and of various stages. The overall incidence of metastases was 40%. The case material was evaluated in detail; the tumors of the inferior limb and those on different sites, e.g., vulva and abdomen, were considered separately. In the group of 188 patients with melanoma of the inferior limb, the incidence of metastases was 42%. In 51%, histologic confirmation was obtained. In the group of 62 patients with melanoma of different sites of the body, the incidence of metastases was 34% and histologic confirmation was obtained in 21 patients. The values of accuracy, sensitivity, and specificity based on the histologic confirmation of the lymphographic reports ranged from 88% to 96%. These data justify the use of lymphography in the initial diagnostic work-up and in the follow-up of these patients.

Lymphography in malignant histiocytosis: case report.

Malignant histiocytosis is an uncommon, progressive disease with a poor prognosis which is characterized by malaise, fever, lymphadenopathy, and splenomegaly. Lymphadenopathy is commonly present at presentation as well as during the course of the disease. The lymphographic findings in this case report were very similar to those encountered in malignant lymphoma, a not unexpected situation since the clinical and pathological resemblances to histiocytic lymphoma are striking.
