Thalidomide has immunomodulatory and anti-angiogenic properties which may underlie its activity in cancer. After its success in myeloma, it has been investigated in other plasma cell dyscrasias, myelodysplastic syndromes, gliomas, Kaposi's sarcoma, renal cell carcinoma, advanced breast cancer, and colon cancer. Thalidomide causes responses in 30-50% of myeloma patients as a single agent, and acts synergistically with corticosteroids and chemotherapy. Thalidomide results in the reduction or elimination of transfusion-dependence in some patients with myelodysplastic syndrome. Responses have also been seen in one-third of patients with Kaposi's sarcoma, in a small proportion of patients with renal cell carcinoma and high-grade glioma, and in some patients with colon cancer in combination with irinotecan. The drug is being investigated currently in a number of clinical trials for cancer. Drowsiness, constipation, and fatigue are common side effects, whereas peripheral neuropathy and skin rash are seen in one-third. A minority of patients experience bradycardia. Thrombotic phenomena are especially common when thalidomide is combined with chemotherapy. Adverse effects severe enough to necessitate cessation of therapy are seen in around 20% of patients. A therapeutic trial of thalidomide is essential in all patients with relapsed or refractory myeloma. In other cancers, the best way to use the drug is in the setting of clinical trials. In the absence of access to studies or alternative therapeutic options, thalidomide could be considered singly or in combination with standard therapy.

We report a case of complication of a catheter port system. A 67-year-old male who had undergone left hemicolorectomy and partial hepatectomy for liver metastases from colon cancer underwent hepatic arterial infusion (HAI) of chemotherapy by a percutaneously implanted catheter port system to prevent recurrence. Eighteen months after the implantation of a port system he complained of intermittent claudication. Intravenous digital subtraction angiography (IV-DSA) showed occlusion of the left superficial femoral artery. The catheter was removed and a femoro-popliteal bypass with an artificial graft was constructed. Thrombus was found around the indwelling catheter at the insertion site. After the operation his complaint disappeared and has been alive without recurrence for 6 years.

Thrombotic complications turn into the second leading cause of death in colon cancer patients due to the hypercoagulable state caused by malignancy. Therefore, it is necessary to treat colon cancer and its thrombosis complications simultaneously. Herein, a nano polymer conjugate based on disulfide cross-linked low-generation peptide dendrimers was developed to treat colon cancer and its thrombotic complications. First, two-generation polyglutamic acid dendrimer was bonded to nattokinase (NK) and then cross-linkers containing disulfide linkages were used to obtain polymer conjugates (NK-G2)n. Then doxorubicin (Dox) was encapsulated. The system can release drugs sequentially due to the dissociation of the polymer conjugates. In vitro thrombolytic experiments exhibited a significant thrombolysis ability of (NK-G2)n. The toxicity and cellular uptake tests on HCT116 cells showed that Dox loaded polymer conjugates had good endocytosis ability and anti-cancer effect. Therefore, this drug delivery system will be a promising strategy to the combined treatment of colon cancer and thrombotic complications.
