A randomized placebo-controlled trial of recombinant human interleukin- 11 in cancer patients with severe thrombocytopenia due to chemotherapy 总被引:18,自引:3,他引:18

Thrombocytopenia is a complication of cancer treatment that can limit dose intensity. Interleukin-11 (IL-11) is a growth factor that increases platelet production. We conducted a multicenter, randomized, placebo-controlled trial of recombinant human IL-11 (rhIL-11) in 93 patients with cancer who had already been transfused platelets for severe thrombocytopenia resulting from chemotherapy. The patients had received platelet transfusions for nadir platelet counts of < or = 20,000/microL during the chemotherapy cycle immediately preceding study entry. Chemotherapy was continued during the study without dose reduction. Patients were randomized to receive placebo or rhIL-11 at 50 or 25 micrograms/kg subcutaneously once daily for 14 to 21 days beginning 1 day after chemotherapy. Eight of 27 (30%) evaluable patients treated with rhIL-11 at a dose of 50 micrograms/kg did not require platelet transfusions versus 1 of 27 (4%) patients who received placebo (P < .05). Five of 23 (18%) patients treated with rhIL-11 at 25 micrograms/kg avoided platelet transfusions (P = .23). Side effects were fatigue and cardiovascular symptoms, including a low incidence of atrial arrhythmias and syncope. There were no differences among treatment groups in the incidence of neutropenic fever, days of hospitalization, or number of red blood cell transfusions. This study shows that rhIL-11 treatment of a dose of 50 micrograms/kg significantly increases the likelihood that patients who have already been transfused platelets for severe chemotherapy-induced thrombocytopenia will not require platelet transfusions during a subsequent chemotherapy cycle. 相似文献

Autologous bone marrow transplantation in follicular non-Hodgkin's lymphoma before and after histologic transformation 总被引:3,自引:2,他引:3

Patients with disseminated follicular non-Hodgkin's lymphoma (NHL) are only occasionally cured with standard chemotherapy regimens. Although most of these tumors are initially responsive to chemotherapy, in 40% to 70% of patients the lymphoma will eventually transform to an NHL of higher grade malignancy and a poorer prognosis. We treated 18 patients having an original diagnosis of follicular NHL with high-dose therapy and autologous bone marrow transplantation. The lymphomas of 10 of the patients had already undergone histologic transformation and eight still had a follicular histologic pattern. The former group had been followed for a longer time from the diagnosis of NHL and had been more extensively treated with conventional chemotherapy regimens. All eight patients with follicular NHL at the time of transplantation are alive for 246+ to 1,804+ days and seven of the patients are in complete remission. In contrast, of the 10 patients in histologic transformation only 1 is alive and in CR. This reflects the inability of these patients to tolerate the high-dose chemotherapy and myelosuppression as well as resistance of their lymphoma to this therapy. This difference in survival between the two groups was highly significant (P = .002). We conclude that the outcome of patients with follicular NHL transplanted early before histologic transformation is better than for those who are transplanted later in the course of their illness. Because of the relapsing behavior of follicular NHL, a longer follow-up is necessary to prove any impact on the natural history of the disease. 相似文献

Crown fractures and luxations occur most frequently of all dental injuries. An appropriate treatment plan after an injury is important for a good prognosis. Guidelines are useful for delivering the best care possible in an efficient manner. The International Association of Dental Traumatology (IADT) has developed a consensus statement after a review of the dental literature and group discussions. Experienced researchers and clinicians from various specialties were included in the group. In cases where the data did not appear conclusive, recommendations were based on the consensus opinion of the IADT board members. The guidelines represent the current best evidence, based on literature research and professional opinion. In this first article of three, the IADT Guidelines for management of fractures and luxations of permanent teeth will be presented. 相似文献
