Restaging of patients with ovarian carcinoma.

Sixty-four patients, 34 with no clinical evidence of disease (NED) and 30 with clinical evidence of disease (ED), were submitted to restaging with peritoneoscopy plus diaphragmatic inspection, peritoneal cytology, and lymphography. Eleven patients (32.2%) in the NED group and 25 (83.3%) in the ED group had positive restaging findings. The 3 diagnostic procedures, in combination, are important in establishing occult disease and therefore in the planning of further treatment.

Lymphography in bone and soft tissue sarcomas. Experiences from three institutions.

The case material was collected from 3 Institutions with a total of 441 patients: 217 with primary bone tumor and 224 with soft tissue sarcomas. In the majority of patients lymphography was performed during the initial diagnostic workup. The lymphograms were interpreted as negative or positive for metastases. In bone tumors, the incidence of metastases was 21%, ranging from 28% for osteosarcoma to 18% for Ewing's sarcoma and 13% for chondrosarcoma. In tumors of the soft tissue, the frequency was somewhat higher (28%), with special regard to rhabdomyosarcoma (53%), anaplastic sarcoma (67%), neurogenic sarcoma (42%) and synovial sarcoma (35%). In the group of bone sarcomas, primary hematogenous spread was 3 times more frequent than lymphogenous spread, while in soft tissue sarcomas, with a higher incidence of lymphatic spread, this finding was inverted. In the more consistent tumor groups, the occurrence of lymphatic metastases indicated a significant worsening of the prognosis. In 96 patients, lymph node biopsies were performed and the radiologic histologic correlation gave evidence of a 97.7% overall diagnostic accuracy.

Are retroperitoneal lymph node metastases a major problem in endometrial adenocarcinoma? Diagnostic and prognostic assessment with lymphography.

The results of foot lymphography in 295 patients with endometrial carcinoma observed from 1968 to 1978 at two institutions are reported. One hundred and eighty-two were new cases, 61 were recurrences, and 52 were patients who underwent restaging diagnostic procedures without clinical evidence of disease. The incidence of lymphatic spread was correlated with the clinical stage, the pathologic stage, and the extent of recurrent disease. In fact, in the 182 new cases, at clinical stage, the pathologic stage, lymphography was positive in 8.9% of patients at Stage I, 28.6% at Stage II, 57.1% at Stage III, and 66.6% at Stage IV disease; at pathological stage, lymphography was positive in 8% of patients at Stage I, 14.8% at Stage II, 39.3% at Stage II, and 53.3% at Stage IV disease. There was lymph node involvement in 47.5% of the 61 pretreated patients. Finally, in 52 pretreated patients with no evidence of disease, the incidence of lymph node involvement was 7.7%. In new cases, metastases were found only in the pelvic nodes in 56.2% of the patients and only in the para-aortic nodes in 9.5%; in 34.3%, both chains were simultaneously involved. The five-year survival rate for patients at Stage I, II, and III disease with positive lymphography was 35% as compared with 73% for negative cases. In patients at Stage I and II, the difference of survival was equal to 24%. The reliability of the results is confirmed by the concordance with the data of the literature on histologic involvement, by the first radiologic-pathologic comparison, and by the clinical course of the positive cases. Lymphography is of unquestionable value for an appropriate staging and for a correct plan of treatment.

Retroperitoneal metastases from ovarian carcinoma: reassessment of 365 patients studied with lymphography.

From 1973 through 1978, 365 patients with ovarian carcinoma were evaluated with lymphography. The extent of disease was assessed by clinical and conventional radiologic examinations, peritoneoscopy with visualization of diaphragmatic leaves, peritoneal cytology, and, in some patients, exploratory laparotomy. The highest incidence of metastases was found in advanced stages (31.1% in stage III and 60% in stage IV) and in recurrences (75.9%). In 87 patients with early disease, the incidence was 9.2%. In 36 pretreated patients with no evidence of disease, this incidence was 11.1%. Biopsies of the nodes were performed in 96 patients: radiologic accuracy was confirmed in 33 of 33 positive and in 55 of 63 negative cases. Of the patients, 33% had metastases only in the pelvic nodes, and 7.9% only in the paraaortic nodes; in 79.1%, both chains were involved simultaneously. These data confirm the importance of lymphography in diagnosis, treatment planning, and surveillance of ovarian carcinoma.

[Clinical value of lymphography in cervical cancer (author's transl)].

From January 1961 to June 1978, 417 patients with cervical cancer were submitted to lymphangiography as part of the initial diagnostic work-up. As regards the distribution by clinical stage of the cases under consideration, there were 187 cases in Stage Ib (44.8%) 99 in Stage II (23.7%) and 131 in Stage III plus IV (31.5%). For the early stages preference was given to a radical surgery plus pre- or postoperative radiotherapy combination (154/417 patients, or 36.9%). On the contrary, the cases which were more developed locally or which presented contra-indications to surgery received radiological treatment alone (263/417 cases, or 63.1%). The overall incidence of positive examinations was 29.9% (10.7% in Stage Ib; 28.3% in Stage II; 58.7% in Stage III and 60.0% in Stage IV). The histologic type on its own did not seem to influence the incidence of lymph node metastases detectable by lymphography. In the 145 patients who had surgical exploration, the overall diagnostic accuracy of lymphography was 82.8% with 3 false positive and 22 false negative reports. The para-aortic chains were involved in 28/417 patients (6.7%). For the negative cases, with all the stages mixed together, a 74.7% 5-year survival rate free of disease was recorded, as compared with the 34.5% found for the positive cases (P less than 0.0001). Similar differences was recorded stage by stage.

Present status of treatment for invasive cervical carcinoma.

The results are presented of a retrospective clinical study carried out on 341 patients affected with cancer of the uterine cervix, with lymphography in the pretreatment diagnostic work-up, treated in our Institute from January 1961 to December 1976. The clinical classification of the patients studied was: 157 cases in Stage I (46.0%), 95 cases in Stage II (27.9%), and 89 cases in Stages III and IV (26.1%). During the period considered, the therapeutic approach for carcinoma of the cervix was practically constant and in line with the therapeutic policy most frequently followed for these neoplasms. For the early stages (9/341 patients or 27.6%) preference was given to a radical surgery and postoperative radiotherapy combination; for borderline cases and "bulky" and "barrel-shaped" lesions, radiotherapy usually preceded surgical treatment to enlarge its indications and improve its results (36/341 patients or 10.5%). The cases that were more developed locally or that presented contraindications to surgery received radiological treatment alone (211/341 patients or 61.9%). Radiotherapy treatment consisted of radium therapy performed with a single application of 226Ra conventional sources, followed by percutaneous irradiation with 60Co-teletherapy in the more developed cases and/or in the presence of lymph node metastases. All the patients were submitted to diagnostic lymphography at the onset of the treatment and 92 (26.9%) had lymph node metastases. In the framework of this clinical review, the 5-year disease-free survival from onset of the treatment varied from 88.2% for the cases at Stage Ib occult, 72.5% for the cases at Stage Ib, 63.8% for the Stage II cases, to 40.5% for the cases at Stage III and IV. The presence of a pathologic report at lymphography makes a considerable difference in terms of disease-free, long-term survival after treatment

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.
