New therapies are required to improve survival and reduce morbidity. Repeated vaccine dosing does not appear to have been explored, so Vaccinia Melanoma Cell Lysate (VMCL) vaccine repetitive therapy was tested, either alone, or combined with chemotherapy. 37 patients (31 Stage IV [M1a(6), b(7), c(18)] and 6 Stage IIIc) were studied using intra-dermal VMCL vaccine therapy. If disease progressed, vaccine was continued with standard chemotherapy (DTIC and/or Fotemustine). Overall survival was assessed and clinical responses were also recorded. From vaccine commencement, median overall follow-up was 10 months. Survivals ranged from 4 to 73 months. Median (mean) overall survival was 10 (23.5) months;overall survival at 1, 2 and 3 years was 40.5%, 21.6% and 10.8% respectively. CR and PR occurred in 18.9% (7) and 18.9% (7) of patients;these were durable for up to 6.1 years in 4 patients. Stable disease was noted in a further 17 patients (45.9%). In 6 patients (16.2%) no response to therapy was apparent. Repeated vaccinations with or without chemotherapy produced strong, durable clinical responses with overall survival > 23 months occurring in nearly 25% of advanced melanoma patients. The overall disease control rate (CR, PR and SD) was 83.7%, including CR in very advanced cases. These results, in a largely unselected population of advanced metastatic melanoma patients, compare very favourably with other regimens, and notably were associated with minimal, if any, toxicity. Further analysis of this approach appears warranted.展开更多

The patients comprising of 9 males and 9 females were median age of 36 years,ranging from 18-53 years at diagnosis. Regarding the initial symptoms,7 patients(2 males and 5 females) showed central diabetes insipidus(CDI) and other endocrine symptoms with thickened pituitary stalk or a mass at the hypothalamic region. Additional 2 patients initiated the disease with CDI with no immediate diagnosis. In the remaining patients,the diseasebegun with single(n = 3) or multiple(n = 1) spinal bone lesion(s) in 4 patients(all males),with multiple bone lesions in 3 patients(1 male and 2 females),with single skull lesion in one female patient and with ambiguous symptoms including hypothyroidism in the remaining one male patient. We also recognized the correlation between pregnancy/childbirth and LCH in 4 patients. In terms of treatment,9 patients received systemic immuno-chemotherapy alone,of which the majority received vinblastine-based chemotherapy while 4 received 2-chlorodeoxyadenosine. Five had a combination of immuno-chemotherapy with surgical resection or radiotherapy,2 had immunotherapy alone,2 had surgical resection followed by observation alone to date. Three patients received hematopoietic stem cell transplantation after extensive chemotherapy. In terms of outcome,15 patients are alive(9 with active disease,6 without active disease),with a median of 66 mo(range 17-166 mo),two died of disease while the remaining 1 lost to follow-up. Based on these results,we think that early diagnosis and rapid introduction of appropriate treatment are essential,in order to overcome the problems relevant to adult LCH.展开更多
