Liposome-entrapped doxorubicin (Lip-Dox) was evaluated in two phase I clinical trials in patients with hepatic malignancy. Patients with metastases from primary gastric or colonic tumours and patients with hepatoma were eligible. Lip-Dox was extremely well tolerated and acute toxicities such as nausea and vomiting were totally eliminated; no antiemetics were used even at doses of 80 mg/m2. Toxicities such as alopecia and myelosuppression were also ameliorated. There were tumor regressions and reductions in hepatomegaly in patients treated on both the weekly and 21-day studies. The maximum tolerated dose (MTD) in the weekly study was 22.5 mg/m2/week and in the 21-day trial the MTD was 70 mg/m2.

2-Chlorodeoxyadenosine (2-CdA) is a purine nucleoside analogue with therapeutic activity in low-grade lymphoproliferative disorders. In addition, 2-CdA has a potent myelosuppressive effect, and it has been shown to be toxic to malignant myeloid cells both in vitro and in vivo. In this pilot study we treated nine patients who had advanced myelofibrosis with myeloid metaplasia (MMM) and progressive hepatomegaly or symptomatic thrombocytosis after therapeutic splenectomy. 2-CdA was administered at 0.05-0.1 mg/kg/d for 7 d for one to five treatment cycles. A reduction in liver size associated with marked improvement in fatigue and control of thrombocytosis and leucocytosis was achieved in seven of the nine patients (78% response rate). In four of the seven responding patients the reduction in liver size was durable (4-28 months) and was associated with a decrease in serum alkaline phosphatase levels. However, no patient had improvement in anaemia, and two of the seven initially responding patients have since died of acute leukaemia or progressive disease. Improvement in bone marrow fibrosis was noted in two of five available post-treatment marrow examinations. Toxicity was mainly myelosuppression, which was severe in two patients. 2-CdA may be considered a palliative therapeutic agent after splenectomy in noncytopenic patients with MMM who have progressive hepatomegaly or extreme thrombocytosis.

Sequestration of circulating immature myeloid progenitors in the chronic myeloproliferative disorder myelofibrosis with myeloid metaplasia (MMM) leads to extramedullary hematopoiesis (EMH), as well as end organ enlargement and dysfunction. When medical therapy is inadequate to control symptomatic myeloproliferation, both surgical resection and/or external beam radiotherapy may provide palliative cytoreduction in specific situations. Therapeutic splenectomy may provide relief of pain, mass effect, an improvement in cytopenias, or even palliation of portal hypertension. However, the risks of perioperative and long-term complications limit the use of splenectomy in MMM to specific candidates. In addition to splenectomy, portal hypertension has been palliated by either elective esophageal variceal ligation or porto-systemic shunting (through either open or invasive radiographic means). External beam radiotherapy can provide palliative cytoreduction in afflicted organs, with the greatest benefit seen in the lungs and spine. Splenic radiation also can provide a decrease in the size of the organ but carries the risk of myelosuppression and potentially increases the risk associated with subsequent splenectomy. Hepatic and abdominal radiation may palliate hepatomegaly and/or ascites, but cytopenias are common and responses brief. Novel therapies aimed at the pathogenesis of the disorder are needed for more efficacious and targeted therapy of MMM.

Modern intensive chemotherapy regimens have improved the prognosis for adult patients with acute lymphocytic leukemia (ALL). With these regimens, the complete response (CR) rates are approximately 75% and long-term disease-free survival (DFS) rates are about 20-35%. For patients with high-risk ALL, DFS rates are only 20% or less. Hyper-CVAD regimen is effective in ALL and aggressive non-Hodgkin lymphomas (NHL) with increased CR rates and DFS rates. Between June 2002 and October 2006, 53 consecutive adult patients with newly diagnosed adult ALL were treated with Hyper-CVAD regimen for six to eight cycles. The alternating courses were given every 3-4 weeks or earlier if count recovery occurred. CR rates of 73.6% were achieved in 39 patients, the estimated 2-year survival rate was 82.9% and the estimated 2-year event-free survival (EFS) rate was 87.3%. Side effects were as expected, mostly attributed to myelosuppression. Analysis of prognostic factors suggested that some previously well-established poor prognostic factors such as the degree of leukocytosis and central nervous system (CNS) or testicular involvement were less important with this dose-intensive regimen. However, patients with mediastinal disease had lower CR rates (P<0.05), with the presence of hepatomegaly and t(9;22) abnormalities had poor survival (P<0.05). Compared with other established adult ALL regimens, Hyper-CVAD regimen was associated with significantly better CR rates, overall survival and EFS rates. The long-term follow-up results of Hyper-CVAD were favorable.

A 39-year-old female presented to The First Affiliated Hospital of Jishou University (Jishou, Hunan) with a fever of unknown origin and progressive abdominal distension. Physical examination revealed generalized lymphadenopathy, multiple non-tender cutaneous nodules, hepatomegaly, splenomegaly and abdominal edema. An axillary lymph node biopsy indicated hyaline vascular type Castleman disease, and color Doppler and computed tomography scans suggested Budd-Chiari syndrome (BCS). Based on the abdominal distension and impairments of the liver and kidneys, an inferior vena cavography and balloon dilatation were performed, confirming the diagnosis of BCS and leading to symptomatic improvement. The patient commenced a combination chemotherapy regimen of cyclophosphamide (0.4 g; days 1-3), vindesine (4 mg; day 1) and prednisolone (100 mg; days 1-5), with no melioration of symptoms. Theprubicin was added to suppress the aggravation of the disease on day six of the chemotherapy cycle. The patient exhibited symptomatic remission for one week, however, she subsequently succumbed to intracranial hemorrhage and infections of the lung and intestine due to long-term myelosuppression following chemotherapy. To the best of our knowledge, this is the first report of BCS in a patient with multicentric Castleman disease without human immunodeficiency virus infection.
