Despite its disastrous past, thalidomide has reentered the medical community. This article reviews available evidence for its potential application to the treatment of some complications of HIV infection. HIV-related conditions in which thalidomide may be useful include aphthous ulcers, wasting, diarrhea, and nodular prurigo. Vigilance must be maintained to minimize adverse effects and prevent fetal exposure.
A group of 11 heavily pretreated patients receiving low-dose thalidomide was compared with a similar group of 10 patients with refractory myeloma treated with a convention-al oral chemotherapy. This study shows that thalidomide is not only effective in controlling the neoplastic clone but more-over, thanks to its low toxicity, allows out-patient management of these subjects.
Colchicine is the treatment of choice in familial Mediterranean fever (FMF) both for attacks and for prevention of secondary amyloidosis. The overall non-responder rate varies from 5-10 to 40%. Thalidomide is known to blunt the acute phase response. We report the efficacy of the addition of thalidomide to colchicine in controlling the febrile attacks and acute phase response in a patient with FMF resistant to 2 mg colchicine per day.
Despite potential side effects dominated by teratogenicity and peripheral neuropathy, thalidomide has recently been used to treat severe ankylosing spondylitis (AS). Over 50 patients have been treated across several 6-12 month open studies. Altogether 68% of the patients improved and the drop-out rate was 19%. Inhibition of NF-kappaB and/or TNFalpha is a putative mechanism for thalidomide efficacy in AS.
Thalidomide comes back forty years after the discovery of its teratogenicity. Due to its antiangiogenic and immunomodulating properties, thalidomide is proposed in the treatment of multiple myeloma but also in the management of erythema nodosus leprosis, cutaneous lupus erythematosus and severe aphtosis.
The occurrence of a left atrial thrombus without a haemodynamic predisposing factor (arrhythmia, mitral valvulopathy, severe left ventricular dysfunction) is a rare event. We report a case during the progression of refractory myeloma, four months after stopping treatment with thalidomide. The promoting haemodynamic factors for left atrial thrombosis in sinus rhythm, described in the literature, had been excluded. In our case the potential role of thalidomide is debatable, in the light of recent publications about venous and arterial thromboses observed with this treatment.
This article contains biological, epidemiological and clinical data on multiple myeloma and the role of proangiogenetic cytokines in the development of this neoplasm. The role of angiogenesis in the transformation and development of multiple myeloma is a topic which is presently readily studied in leading scientific centres in many parts of the world. Serum and bone marrow levels of cytokines such as VEGF, b-FGF, IL-6, sIL-6R, HGFare raised in patients with multiple myeloma as compared to healthy subjects; their values correlate with the severity of disease and are presently recognised as prognostic factors. Thalidomide has anti-inflammatory, immuno-modulating and antiangiogeneic properties but the mechanism of its action is not yet completely understood. Thalidomide is presently used in therapy of patients with resistant and relapsed multiple myeloma with very promising results.
A proteasome inhibitor with a new molecular target (PS-341: bortezomib) was recently developed, and its efficacy in the treatment of refractory multiple myeloma has been reported in the United States. Here, we present a 54-year-old Japanese male patient with refractory multiple myeloma resistant to thalidomide. In 1998, the patient was diagnosed as having multiple myeloma (IgG-kappa) and underwent chemotherapy, autologous hematopoietic cell transplantation and interferon therapy, but the disease recurred. In December 2002, thalidomide and high-dose dexamethasone therapy was initiated, and while this combination therapy was effective at first, the multiple myeloma became unresponsive. On 23 June 2003, bortezomib therapy with the following regime was therefore started: 2.2 mg (1.3 mg/m2) of bortezomib was injected intravenously on days 1, 4, 8 and 11, and after a one-week break, another cycle was performed. Starting on day 8 of the administration, the serum total protein, IgG, serum calcium and LDH levels decreased rapidly, and after day 45 of the administration, blood transfusion was no longer needed. Since this is the first report of the use of bortezomib in the treatment of refractory multiple myeloma in Japan, further monitoring of this patient will provide extremely valuable information for developing a therapy against this disease.
This review article discusses the thalidomide therapy of diseases such as systemic sclerosis, rheumatoid arthritis, Behçet syndrome, lupus erythematosus disseminatus and graft-versus-host disease. The main mechanism of action of thalidomide in these diseases is probably based on the suppression of tumor necrosis factor-alpha and the modulation of interleukins.
The angiogenesis is an early event in tumorigenesis. Angiogenesis inhibitors have been developed and are now studied in clinical trials. Angiogenesis research has induced a renewal of thalidomide. Thalidomide inhibits tumoral angiogenesis, allowing a good palliative treatment for hematological malignancies, especially for multiple myeloma and myelodysplastic syndromes.
Advanced human pancreatic cancer is considered a chemoresistant disease. To date, no treatments have had a significant efficacy on the disease. Patients with pancreatic cancer, however, experienced an improvement in the related symptoms with gemcitabine. Thalidomide has been shown to have antiangiogenic and immunomodulatory effects, including the inhibition of vascular endothelial growth factor, basic fibroblast growth factor and tumor necrosis factor alpha. The reported biological consequences of COX-2 up-regulation include inhibition of apoptosis, increased metastatic potential and promotion of angiogenesis. These events may contribute to cell transformation and tumor progression. Antiangiogenesis represents a significant new strategy for cancer treatment; however, most tumors are biologically heterogeneous, especially in endothelial cell diversity. As vessels of most solid tumors are structurally and functionally abnormal, tumor vessels differ from normal blood vessels in their responses to antiangiogenic agents. Therefore, it is important to accept a wide range of different inhibitors, such as thalidomide and selective COX-2 inhibitors, with conventional cytotoxic agents. Here we show a case of advanced pancreatic cancer with remarkable improvement in tumor shrinkage, CA19-9, and a cessation of dirty exudate from umbilicus.
Among 199 patients treated with thalidomide for multiple myeloma, four thromboses occurred in 49 cases during erythropoietin therapy (prevalence 8.1%; annual rate 7.25%), and another 14 events occurred in patients not on erythropoietin (9.3%; 7.56%). Thus, erythropoietin would seem not to increase the risk of thrombosis of myeloma patients receiving thalidomide.
Malignant mesothelioma (MM) is a rare neoplasm that is commonly fatal within 12-17 months after diagnosis. There are no widely accepted curative approaches. It recurs even after the most aggressive surgical resection. MM is resistant to chemotherapy and radiation. Most of the chemotherapeutics have been evaluated in MM, however, no drugs have a response rate greater than 20%. The combination of drugs has no increased efficacy compared with single agents. Vinorelbine has useful clinical activity against MM with a response rate of 24%. Vascular endothelial growth factor (VEGF) is expressed in MM and pleural effusion of MM. There is a significant inverse correlation between serum VEGF levels and MM patient survival. Cyclooxygenase-2 (COX-2) is expressed in MM. COX-2 plays an important role in tumor growth, invasion, and angiogenesis. VEGF and COX-2 are potential targets in MM. The downregulation of bFGF, VEGF, and maybe some other angiogenesis stimulators, is one of the antiangiogenic mechanisms of thalidomide. Celecoxib is a potent selective COX-2 inhibitor. Here we report a case of disseminated malignant mesothelioma of peritoneum responding remarkably to thalidomide, celecoxib, vinorelbine and CDDP.
OBJECTIVE: To study the therapeutic effect of thalidomide (Tha) on murine hepatocellular carcinoma. METHODS: In murine transplanted hepatoma model, thalidomide was administered intragastrically alone (200 mg/kg daily for 10 days) or in combination with doxorubicin. The antitumor activity of Tha was observed in solid and ascitic tumor models. RESULTS: Tha induced significant growth inhibition of solid hepatoma without obvious toxicity on peripheral blood cells and lymphocyte proliferation. Although Tha alone had no effect on the survival of mice with ascitic tumor, it showed a synergistic antitumor activity in combination with doxorubicin (Dox) in both solid and ascitic tumor models. Moreover, Tha reduced Dox-induced cytopenia and immunosuppression. Histological analysis of Tha-treated tumors revealed remarkably enhanced tumor necrosis and lymphocyte infiltration on the edge of tumor tissues. CONCLUSION: Tha has definite therapeutic effect on murine hepatoma, and the combination with Dox shows an enhanced therapeutic potential.
BACKGROUND AND OBJECTIVES: Thalidomide plus dexamethasone (Thal/Dex) has emerged as an effective alternative to vincristine, doxorubicin and dexamethasone as a pre-transplant induction therapy for newly diagnosed multiple myeloma. However, many patients treated initially with Thal/Dex do not proceed to autologous stem cell transplantation (ASCT) and the time to progression and other outcome measures with Thal/Dex as primary therapy for multiple myeloma are not known. We present the first data on the outcome of patients with newly diagnosed multiple myeloma treated with Thal/Dex who did not undergo upfront ASCT. DESIGN AND METHODS: We identified 21 patients with newly diagnosed multiple myeloma treated with Thal/Dex on a phase II clinical trial who did not undergo ASCT due to age, comorbidity or the patient's refusal. Patients received thalidomide at a dose of 200 mg/day orally and dexamethasone 40 mg daily on days 1-4, 9-12, 17-20 (odd months) and days 1-4 (even months). Cycles were repeated every 28 days. RESULTS: The median age was 66 years (range 36-78). The median duration of follow-up was 21 months (range 1-52). One (5%) patient achieved a complete response, and 9 (43%) had a partial response, so the overall response rate was 48%. Of the remaining patients, 7 (33.3%) had stable disease, one patient did not respond, and three died while on therapy prior to response assessment. The median overall survival and time to progression were 21 months and 18 months, respectively. INTERPRETATION AND CONCLUSIONS: The median time to disease progression in patients with multiple myeloma who receive initial therapy with Thal/Dex and who do not undergo ASCT is 18 months.
The aim of this prospective, multicenter, phase II study was to investigate the combination of pegylated liposomal doxorubicin (Caelyx) 40 mg/m2 on day 1 every 28 days, dexamethasone 40 mg p.o. on days 1-4 and 9-12 and thalidomide 100 mg daily in 50 patients with advanced multiple myeloma. Twenty-six percent of patients achieved a complete response, 6% a near complete response, 6% a very good partial response, 38% a partial response, 16% a minor response and 8% progressed, for an overall response rate of 92%. The median event-free survival was 17 months and the median overall survival was not reached. Grade 3 non-hematologic toxicity occurred in 12% of patients, thromboembolic disease in 12% and severe infection in 16%. The combination of pegylated liposomal doxorubicin, dexamethasone an thalidomide is safe and very effective in advanced multiple myeloma.
Recent clinical experience with the use of thalidomide in inflammatory bowel disease is the focus of this article. Although widely used in Crohn's disease, thalidomide therapy in patients with ulcerative colitis, children with Crohn's disease, as well as patients with Crohn's disease associated with upper gastrointestinal and genital tract involvement have been occasionally reported.
Two female patients, 86 and 80 years of age, had been treated with blood transfusions for several years and several months, respectively, due to iron-deficiency anaemia caused by gastrointestinal blood loss. Angiodysplasias were detected and subsequently coagulated in the course of repeated gastroscopies and colonoscopies. Due to the failure of this treatment, treatment with thalidomide was started. Thereafter, the gastrointestinal bleeding stopped and there was no longer any need for blood transfusions. Treatment with thalidomide seems an effective therapy for patients with frequently recurring gastrointestinal blood loss due to angiodysplasias who no longer tolerate conventional and invasive procedures due to their physical condition.
