Abstract: Autologous stem‐cell transplantation (ASCT) has emerged as the standard approach in patients with multiple myeloma, although it is unlikely to achieve cure. Thalidomide maintenance and non‐myeloablative allogeneic transplantation (NST) may increase complete remission (CR) rate and increase overall survival. In this study, 35 ASCT and 10 NST were performed in 33 patients. Patients, who were resistant or relapsed following ASCT, underwent NST if they had an HLA‐matched sibling, otherwise treated with a second ASCT. Thalidomide was started as maintenance after ASCT. After first transplantation, three patients underwent second ASCT and 10 patients underwent NST. Following first transplantation, CR rate was 39% and increased to 60% (overall response 93%) with addition of thalidomide, bortezomib, and second transplantation. CR was durable in 14 (42%) patients. During a median follow‐up of 24 months, 18 patients progressed and nine patients died. The 100‐d transplant‐related mortality was <5%. The four‐yr progression‐free survival (PFS) was 52.4%. In conclusion, ASCT followed by thalidomide and NST in resistant patients can lead to high CR and PFS rates. As a second transplantation has not been performed routinely, patients having durable CR had a chance to avoid or delay a second transplantation without compromising disease control. 相似文献

This study was designed to explore the value of markers of bone turnover, macrophage inflammatory protein-1alpha (MIP-1alpha), and osteopontin (OPN) in the diagnosis of myeloma bone disease. Twenty-five patients with newly diagnosed and untreated multiple myeloma (MM), and 22 age-, sex-, and bone mineral density-matched control subjects were enrolled. Levels of MIP-1alpha, OPN, carboxy-terminal telopeptide of Type-1 collagen (C-telopeptide or Ctx), deoxypyridinoline (DPD), Type-1 collagen propeptide (T1Pro), and bone-specific alkaline phosphatase (BALP) were assessed in both groups. Twenty-two of the patients had bone involvement documented by skeletal surveys and lumbar spinal magnetic resonance imaging. Levels of serum Ctx, OPN, MIP-1alpha, and urine DPD were significantly higher in MM patients with bone disease than in controls (P<0.01). Serum Ctx levels were elevated in 90.9% of patients with MM and 40.9% of controls (P<0.001). Urine DPD levels were elevated in 90.4% of the patients and 31.8% of the controls (P<0.001). The serum OPN and MIP-1alpha levels of the patients were significantly correlated with beta2-microglobulin and lactate dehydrogenase levels (P<0.05). Our study indicates that Ctx and DPD are sensitive markers of bone disease in MM, and higher than normal values suggest presence of bone disease rather than benign osteoporosis in MM. The utility of OPN and MIP-1alpha needs to be further investigated. 相似文献

The optimal reconstruction of the mandible and of the temporo-mandibular joint after mandibular hemi-resection with disarticulation is still controversial in literature. This paperwork presents our experience on four cases in the reconstruction of the mandible together with the inferior arthroplasty of the temporo-mandibular joint, after the resection of extended benign tumors of the mandible, based on fibular free vascularized grafts having attached a Stryker titanium condylar prosthesis reconstructing the inferior segment of the temporo-mandibular joint. Our results for the this technique were excellent, with a functional rehabilitation very close to normal. After reviewing the various techniques and their arguments in literature, with accent on the TMJ reconstruction, we consider this method to be optimal for the reconstruction of mandibular defects in patients with neoplastic conditions. 相似文献
