Curative treatment for Hodgkin's disease for patients who are pathology-staged IIIA, spleen-positive, consisted of total nodal irradiation (TNI) alone at the University of Minnesota Hospitals prior to 1975. This approach has been modified since 1975 to give low-dose irradiation to the liver in addition to TNI because of the high recurrence rate with TNI alone. Recurrence-free survival improved significantly when the liver was irradiated as compared to results with TNI alone (78% vs. 41% at 5 years, p = 0.004). The 5-year, overall survival was not significantly different in the two groups (90% vs. 80% at 5 years, p = 0.373). Various prognostic factors were examined. Patients who received liver treatment had statistically significant improvement in recurrence-free survival as compared to patients who did not receive liver treatment in the following categories: anatomic substage IIIA1, histologic classification of nodular sclerosis, male gender, age less than 40, number of primary sites, and extent of splenic disease. However, these factors failed to show clinical significance as prognostic factors. We conclude that TNI with low-dose liver irradiation should be used as the primary modality of treatment of Hodgkin's disease, pathology-staged IIIA patients. We conclude that chemotherapy should be reserved for recurrences in view of the excellent current results and the lesser risk from treatment, especially the risk of carcinogenesis.

Sixteen patients (median age 67 yrs.) with non-Hodgkin lymphoma of the testis were studied. Twelve of these patients had disease that was classified as local (Stages IE and IIE). Eight patients had diffuse histiocytic lymphoma, 6 had diffuse poorly differentiated lymphocytic lymphoma, 1 had both lymphoma and seminoma, and 1 had nodular poorly differentiated lymphocytic lymphoma. The overall median survival was 9.5 months. Para-aortic nodal involvement was the factor that had the strongest prognostic influence with the management methods used. Median survival without para-aortic nodal involvement was 57+ months, but with such involvement it was 6 months (p = 0.002). There is a high probability of generalized disease if lymphoma can be detected in the para-aortic nodes. For patients with Stages IE and IIE disease, radical radiation therapy is the preferred treatment. For those with disseminated disease, chemotherapy, with irradiation reserved for symptomatic and bulky localized deposits, is the recommended method of management.

Seventeen patients with cutaneous melanomas of the nose were treated at the M. D. Anderson Hospital during the years 1944-1978. The local recurrence rate was 6 per cent. The two-year survival rate was 82 per cent; the five-year survival rate, 29 per cent; the ten-year survival rate, 12 per cent. Only 20 per cent of the patients developed histologically positive lymph nodes, and all died of the disease. Wide local excision with skin grafting is the treatment of choice, with a modified neck dissection and/or superficial parotidectomy reserved for subsequent nodal metastasis.

Between January 1, 1971 and December 30, 1977, 82 patients underwent bilateral pelvic lymph-adenectomy for carcinoma of the prostate, 65 with associated radical prostatectomy. Lymph node metastases were noted in 27 cases: 1 of 8 with A2, 3 of 16 with B1, 12 of 39 with B2 and 11 of 19 with C tumors. Of the 17 patients undergoing lymphadenectomy only as a staging procedure before definitive radiation therapy 12 had nodal involvement, while 15 of 64 patients with combined lymphadenectomy and prostatectomy had nodal disease. Early complications involved 6 patients with thromboembolic disease, including 1 death while the patient was hospitalized of pulmonary embolism. All 6 thromboembolic complications occurred among 52 patients who had not received anticoagulation, for an incidence of 11.5 per cent compared to no episode of thromboembolism among 30 patients prophylactically anticoagulated with warfarin sodium. Late complications of chronic lymphedema occurred in 15 patients, 10 of whom had postoperative radiation. We recommend lymphadenectomy as an adjunct to radical prostatectomy but its role as a staging procedure before definitive radiation therapy to the pelvis appears to yield increased morbidity in terms of incidence of chronic lymphedema, suggesting that its use be reserved for highly selected patients. We also recommend the prophylactic postoperative administration of anticoagulants and patients awareness of risk factors contributing to chronic lymphedema.

Between 1965 and 1989, 1180 patients at Indiana University, U.S.A., underwent retroperitoneal lymph node dissection (RPLND) for non-seminomatous germ cell (NSGC) testis cancer of whom 638 cases had primary RPLND. A subset of 174 cases were considered clinical stage B (or II) before surgery (retroperitoneal nodal metastases by clinical staging). Surgery revealed that 23% (n = 41) had pathological stage A disease (no cancerous nodes). This error rate in clinical staging has decreased somewhat with improved techniques, but remains approximately 20% over the last decade. The relapse rate in pathological stage A (n = 41) was 5% (n = 2), both of whom were cured by chemotherapy. The relapse rate in pathological stage B without postoperative adjuvant treatment (n = 54) was 35% (n = 19); 2 patients died. This indicates that 65% of pathological stage B cases were cured by RPLND alone. From 1979 to 1989, the 140 pathological stage B cases participated in a randomised prospective trial of post-RPLND adjuvant chemotherapy versus no postoperative treatment. Forty two per cent (n = 59) received postoperative platinum-based therapy (two cycles), and there has been no relapse after RPLND for stage B disease. While advances in chemotherapy for NSGC testis cancer have led to its application by several study groups to clinical stage B (or II) testis cancer (with surgery reserved only for those in partial remission), the equivalent cure rate with RPLND surgery with chemotherapy rescue reserved for those who relapse appears to have both cost and risk-benefit advantages.

A more accurate method of detecting nodal disease in squamous cell carcinoma of the tongue is needed so that treatment of the neck with its associated morbidity can safely be reserved for patients who actually have metastatic disease. Tumor angiogenesis and the expression of the p53 antigen--which have each been shown to be predictive of metastasis in breast and colon cancer, respectively--are examined for their ability to predict neck metastasis in tongue cancer. Fifty-seven patients with T1 and T2 squamous cell carcinoma of the oral tongue, whose neck disease was examined by dissection or by 2-year follow-up, were studied. Twenty-eight patients (49%) were node positive and 29 patients (51%) were node negative. The primary tumors were immunohistochemically stained for the p53 antigen and for factor VIII, which allowed the blood vessels within the tumor to be quantitated. The mean vessel counts per x200 high-power field were 59.8 and 61.5 for node-positive and node-negative patients, respectively (p = 0.8). Node-positive patients showed overexpression of p53 43% of the time, vs. 61% for node-negative patients (p = 0.17). Multivariate analysis confirmed that no difference in tumor angiogenesis or the expression of the p53 antigen was found between tumors that had metastasized and those that had not. Therefore neither tumor angiogenesis nor the p53 tumor marker is clinically useful in determining lymph node metastasis in these patients.

Twenty eight patients with stage II A and twenty patients with stage II B testicular seminoma were treated at this institute between January 1982 and December 1988. The three year crude survival observed in this retrospective analysis was 82% and 75% respectively. Post orchiectomy infradiaphragmatic radiotherapy was the mainstay of the treatment. In stage II A 4 patients were administered adjuvant chemotherapy as well. Prophylactic Mediastinal Irradiation (PMI) was not employed as a routine in this subgroup. Eight patients (28%) relapsed (Mediastinal Nodes--4, Pulmonary--3, Scrotal--1). In stage II B twelve patients were treated with primary abdominal radiotherapy and of them 4 were delivered PMI as well. Induction chemotherapy was administered in remaining 8 patients. Seven patients (35%) relapsed (Pulmonary-4, Mediastinal Nodes-3). Mediastinal recurrence was noted only in those who were treated with abdominal radiotherapy alone. Though salvage chemotherapy proved successful in 5 of the seven patients (70%) with nodal relapse, none of the patients with extranodal relapse responded to subsequent chemotherapy. For stage II A we recommend abdominal radiotherapy alone and for stage II B Induction chemotherapy is advised keeping radiotherapy reserved for residual mass. We do not advocate PMI as a routine in stage II testicular seminoma as no survival benefit is observed.

This retrospective study quantitatively assessed the effects of magnetic resonance imaging (MRI) and computed tomography (CT) on the staging of laryngeal cancer. A blind comparison between CT and MRI was made in a group of previously untreated patients with squamous cell carcinomas of the larynx. From June 1992 to November 1993, 29 patients were eligible for study. Of these, 14 patients (48%) had supraglottic lesions, 11 patients (40%) had glottic lesions and 4 patients (14%) had both. No subglottic lesions were seen. The data suggest that clinical staging of laryngeal tumors is inadequate. MRI proved superior to CT for staging tumors, especially those confined to the supraglottis. Nevertheless, clinically staged T1 or T2 lesions could be adequately assessed by CT alone. Findings also indicate that MRI should be reserved for T3 or T4 clinically staged lesions. Furthermore, most nodal disease can be staged by CT.

Atrial arrhythmias resistant to medical therapy are still a common indication for ablation of the normal atrioventricular conduction pathway (Tawara node and His Bundle). However, the development of catheter techniques of intra-atrial ablation to destroy arrhythmogenic myocardial zones enables radical cure of the arrhythmias with the respect of the nodo-hisian pathway. With respect to common flutter, a number of series, including our own, show a 50 to 75% long-term success rate. We believe that a very high success rate in the ablation of flutter will probably be achieved in a reproducible manner but this will require a more accurate understanding of the tachycardia circuit and technological developments allowing controlled radio-frequency destruction of bigger atrial myocardial zone. Experience of radio-frequency ablation atrial of atrial extrasystoles is more limited than that of flutter and there are fewer published series. Globally, catheter ablation of atrial tachycardia remains a more difficult and a less well codified procedure than that of accessory pathways or of intra-nodal reentry. Radio-frequency ablation in this indication is not without danger in view of the thinness of the atrial wall. We believe that radio-frequency catheter ablation for atrial arrhythmias should, for the moment, be reserved for centres specialised in the techniques of electro-physiological investigation and ablation.

Radiologic imaging provides crucial information about bronchogenic cancer and is complementary to more invasive diagnostic techniques. The diagnosis is often suspected initially from the chest radiograph. The CT scan permits the most complete analysis of the extent of the tumor, nodal metastasis, and distant metastasis and serves as a guide to further evaluation and surgery. MRI, at the current stage of development, is generally reserved for cases in which CT findings are inconclusive. Rapid technologic advances have the potential for altering this imaging hierarchy in the near future.
