[Chronic renal insufficiency in the terminal stage. Therapeutic possibilities offered by repeated dialysis and transplantation in the absence of selection. Apropos of 136 cases].

Repeated dialysis in hospital or at home, and renal transplantation, carried out mainly with cadaver kidney, should permit in France, in the near future, treatment of all patients with chronic terminal renal failure. This report shows the results obtained between the 1st of November 1972 and the 1st of January 1975 in 136 patients treated without any selection at the Nephrology Department and Renal Transplantation Unit of the Pitié-Salpĕtrière Hospital in Paris, in connection with 20 public and private dialysis centers. 66 patients, i.e. 45% of all, were "high risk" patients, mainly because of their age or cardiovascular condition. The overall percentage of survival rate at 2 years in dialysed patients was 81%. It was 67% in the high risk group and 94% in the others. About half of the deaths occured because of cardiovascular reasons. 82 patients were considered for transplantation. Owing to the lack of donors, the number of transplanted patients was only 21. 19 transplantations were carried out with cadaver kidneys. On the 31st of December 1974, 15 patients, i.e. 71% lived with a functioning transplant. In the reported series, complete rehabilitation was obtained in 30% of cases. The results obtained justify, in our opinion, the policy of non-selection of patients.

[Kidney transplantation from living related donors: experiences from one center].

Living related donor (LRD) renal transplantation has remained underdeveloped in France up until now. The reduction of the number of available grafts and especially the superiority of the results of LRD transplants recently led us to develop this type of transplantation. We present the retrospective analysis of our experience of 63 cases from March 1973 to June 1995. The actuarial graft survival rate was 91% at 1 year and 87% at 3, 5 and 10 years. The 5- and 10-year survival rates of HLS-identical transplants (n = 17) was 100%. The donor morbidity was minimal (2 cases of parietal suppuration, 1 pulmonary atelectasis). These results emphasize the superiority of LRD transplantation, which also has the advantage of allowing transplantation of hyperimmunized patients in whom the waiting time for a brain-dead donor kidney is long and unpredictable.

Non-Hodgkin's lymphoma of the paranasal sinuses: clinical and pathological features, and response to combined-modality therapy.

PURPOSE: Lymphomas of the paranasal sinuses may have poorer prognoses compared with other extranodal lymphomas of the head and neck, and are not well defined as a particular clinicopathologic entity. The outcome of combined-modality therapy and central nervous system (CNS) prophylaxis has not been fully determined. PATIENTS AND METHODS: We retrospectively reviewed our experience with 16 consecutive, carefully defined patients, all treated with both chemotherapy and radiotherapy. RESULTS: There were 11 men and five women, mean age 52. All presented with local symptoms; 13 had stage I or II disease. Thirteen had diffuse large cell lymphoma, two diffuse mixed, and one small noncleaved. Phenotyping revealed 10 B-cell, four T-cell, and two T or natural killer (NK). Most received CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) chemotherapy; the order of chemotherapy and radiotherapy varied. Twelve received CNS prophylaxis. Of 12 complete responses, six relapsed, all at distant sites, and two died during initial therapy. Five-year survival was 29%, and median survival 18 months. Four of 10 B-lineage patients were relapse-free at 4 years; all six T- or T/NK-lineage patients relapsed or were dead within 6 months. Tumors of T or NK lineage often expressed CD56 and showed evidence of Epstein-Barr viral infection; otherwise, pathological features were not predictive of lineage or outcome. Neither age nor lactate dehydrogenase predicted prognosis. No complete responder recurred in the CNS as site of first relapse. CONCLUSION: Despite localized stage at presentation, sinus lymphoma is an aggressive disease, characterized by distant relapse and early mortality. Combined-modality therapy with CNS prophylaxis improves outcome compared with radiotherapy alone; however, prognosis remains poor. Patients with T-lineage disease appear to have a particularly bad outcome. Autologous bone marrow transplantation should be evaluated as first-line therapy for those at high risk of relapse.
