    • The incidence of cutaneous malignant melanoma is rising, and tumour markers are attracting attention as a possible alternative to clinical examination in the follow-up situation. S100 is the preferred marker for malignant melanoma, and correlation between serum S100 and disease relapse and survival has been reported. S100 tests previously used in clinical studies were specified poorly regarding reactivity with S100A1B and S100BB. In this study, a newly designed S100 assay (designed to measure exclusively S100A1B and S100BB) and two newly developed serological assays, S100A1B, and S100BB, were investigated postoperatively in patients undergoing radical surgery for cutaneous malignant melanoma. Additionally, immunohistochemical analysis of S100A4 was performed on the primary malignant melanoma using tissue microarrays. The primary aim of the study was to investigate whether any of these assays, either singly or in combination, can contribute additional information concerning increased risk of relapse and death because of malignant melanoma. In total, 98 patients (54 males, 44 females) with malignant melanoma were included in the study. As a continuous variable, S100BB (P=0.016) was associated statistically with increased risk of relapse; this was not the case for increased values of either S100 (P=0.11) or S100A1B (P=0.92). The Kaplan-Meier overall survival as well as disease specific survival curve for the S100 serum level demonstrated a statistically significant association with better survival if the patient had a S100 level

  • Alternating chemo-immunotherapy with temozolomide and low-dose interleukin-2 in patients with metastatic melanoma
  • 2006
  • Ingår i: Melanoma research. - : Ovid Technologies (Wolters Kluwer Health). - 0960-8931 .- 1473-5636. ; 16:4, s. 357-363

    • Temozolomide is a rapidly absorbed chemotherapeutic agent, achieving significant central nervous system penetration. Previous clinical trials suggested that temozolomide in sequence with low-dose recombinant human interleukin-2 might be an efficacious and relatively non-toxic chemo-immunotherapeutic treatment, which may synergistically eliminate tumours. The primary objective was to determine the safety and tolerance of temozolomide administered orally 200 mg/m(2) days 1-5, in sequential combination with subcutaneous injections of 4.5 x 10(6) IU recombinant human interleukin-2 on days 8-11, 15-18 and 22-25 in patients with measurable, progressive metastatic malignant melanoma without radiological signs of central nervous system metastases. The secondary objectives were to determine tumour response and time to progression. Twenty-seven patients were included, of which four were non-evaluable for response. Twenty-three patients tolerated the regimen with side effects below grade 3 according to the World Health Organization (WHO) scale. Three patients suspended the treatment because of WHO grade 3 side effects already during the first 3 days of the first course of temozolomide. Seven patients showed no tumour progression during the first four treatment cycles. Two patients had complete responses, three partial responses and two stable disease at the end of the four cycles defined by the protocol and they continued the treatment until signs of relapse or a maximum of 21 courses. Five of these patients are still alive. Thrombocytopenia was significantly more pronounced in patients with objective response and stable disease than in non-responders to therapy. The median time to progression for all patients was 3.1 months and for responding and stable disease patients was 15 months. Five of 23 treated patients (22%) developed brain metastases during follow-up. Temozolomide in combination with recombinant human interieukin-2 is a well-tolerated regimen for outpatient treatment and the bio-chemotherapy combination induced durable clinical responses. Thrombocytopenia might be a positive predictive factor for response to therapy.
