[Intralymphatic administration of adoptive (LAK) immunotherapy in the treatment of patients with metastatic cancer resistant to conventional therapies].
Between January, 1990 and May, 1991, we administered LAK immunotherapy using the intralymphatic route to 25 patients with metastatic cancer resistant to conventional therapies. In the preparation of the immunotherapy, we followed the technique described by Pizza G. et al. The age of our patients ranged between 50 and 75 years and their Karnofsky's indexes were above 70%. The histological type of the metastasis were determined by Rx, ECO and/or CAT before and after the administration of the immunotherapy. In the intralymphatic administration, we followed the technique described by Pizza G. et al. The immunological therapy was administered on days 1, 21, 90 and 111 and the clinical response was assessed by RC, RP, EE and F. The immunological behaviour of the host was assessed through the determination of lymphoid populations (CD2, CD4, CD5 and CD8) and cytolytic cells were studied with monoclonal antibodies CD and CD16. Such immunological study was carried out before the administration of each immunotherapy series. In 7 out of 25 patients (28%), we were able to administer the four LAK series. Such patients were subsequently studied, observing that, although tumoral lesions did not increase in size, they did not disappear and, thus, they were classified as clinically stable. Clinical and analytical toxicity was null. The immunological study did not show any statistically significant changes and the activity of cytotoxic cells (NK) was not modified.
