Thalidomide has several mechanisms of action: several immuno-modulatory properties, an anti-angiogenic action and a hypnosedative effect. Thalidomide has been used in several cutaneous inflammatory disorders (such as erythema nodosum leprosum in lepromatous leprosy, cutaneous lupus erythematosus, severe aphtosis), cancers (relapsed/refractory multiple myeloma) and inflammatory conditions. Several side effects are associated with thalidomide; some are major: teratogenicity, peripheral neuropathy and deep venous thrombosis; some are minor, such as somnolence or abdominal pain and endocrinologic disturbances. Use of thalidomide is strictly controlled with close adherence to a birth control program and close monitoring for early development of peripheral neuropathy.

A 35-year-old healthy male with no history of any past medical illness developed severe headache, vomiting and drowsiness while at high altitude (4,572 m) in the eastern Himalayan ranges. He was evacuated to a tertiary-care hospital where he was diagnosed to have cerebral sinus venous thrombosis (CSVT) on magnetic resonance imaging, with deep vein thrombosis (DVT) of his right popliteo-femoral vein on color Doppler study. Investigation for thrombophilia revealed protein S (PS) deficiency in this patient. Family screening revealed low levels of PS in two elder brothers. One brother had a history of 'stroke in young' at the age of 20 years with the other being asymptomatic. This established the hereditary nature of PS deficiency. We are not aware of any previously published report on hereditary PS deficiency combined with CSVT and DVT occurring at high altitude. However, 1 case of protein C deficiency with CSVT has been reported previously.

To obtain approval from the Ministry of Health, Labor and Welfare of Japan, a phase II study was conducted to assess the pharmacokinetics and pharmacodynamics of thalidomide along with its efficacy and safety in Japanese patients with multiple myeloma. Between 2005 and 2006, 42 patients were enrolled, and 37 patients met eligibility criteria. Of the 37 patients, 3 were excluded from efficacy analysis because of short duration of thalidomide administration (<4 weeks). The overall response rate was 35.3% (12/34), including partial response of 14.7% (5/34) and minimal response of 20.6% (7/34). The adverse events observed in high frequency (>40%) were leukopenia, neutropenia, drowsiness, dry mouth, and constipation. Grade 3 neutropenia was observed in nine cases. Peripheral neuropathy and eruption were observed in about one-quarter of the patients. Deep vein thrombosis was not observed. At a single oral dose of thalidomide (100 mg), the C (max) was 1.68 +/- 0.41 microg/ml, T (max) was 4.54 +/- 1.71 h, T (1/2) was 4.86 +/- 0.44 h, and AUC was 15.87 +/- 3.05 microg h/ml. Low-dose thalidomide was an effective and tolerable treatment for Japanese patients with relapsed/refractory myeloma. Leukopenia and neutropenia were the most serious adverse events. The pharmacokinetics was similar to those observed in Caucasian patients.

After decades of disuse because of its teratogenic effects, thalidomide has had a resurgence of use as a promising therapeutic agent for multiple myeloma. Its mechanism of action involves activation of the immune system, antiangiogenic effects, and inhibition of cytokines. Thalidomide does not interact with the cytochrome oxidase system. It is not significantly metabolized, but it does undergo nonenzymatic hydrolysis in plasma. The resulting products are inactive. Despite the potential adverse effects of peripheral neuropathy, constipation, deep vein thrombosis, somnolence, rash, and orthostatic hypotension, thalidomide is an effective first-line agent for multiple myeloma in combination with dexamethasone or melphalan and prednisone. It has also been studied in the palliative care of patients with cytokine-based syndromes such as anorexia-cachexia syndrome. This review describes its use in oncology, hematology, and palliative care.

Thalidomide is now recognized as an important agent for multiple myeloma. In this study, we retrospectively analyzed the effect of thalidomide therapy in 52 patients with relapsed/refractory multiple myeloma. Median age was 70 years. Eight patients were treated with thalidomide alone, 36 with dexamethasone, and 8 with chemotherapy. The maintenance dose of thalidomide was 100 mg/day in 42 cases. The probability of overall survival and progression-free survival one year after the start of thalidomide were 76.2% and 70.9%, respectively. Complete or partial response was obtained in 16 patients (31%). The probability of survival was better in patients who obtained a partial or complete response than in non-responders (P=0.04). Adverse effects (CTCAE criteria Grade 3-4) were somnolence (n=3), constipation (n=5), peripheral neuropathy (n=1), deep vein thrombosis (n=1), anemia (n=10), leukocytopenia (n=10), and thrombocytopenia (n=3). The high incidence of cytopenia in this study suggests that the Japanese population tends to display bone marrow suppression after thalidomide therapy. Some patients developed peripheral neuropathy at the early stage of administration and attention was necessary. In conclusion, thalidomide therapy is safe and effective in patients with refractory multiple myeloma.
