The target antigen was identified as SMN complex (Gemin 3, Gemin 4, SMN, and Gemin 2, respectively), which plays a critical role in the assembly of snRNP. In immuno-fluorescence analyses, all 3 sera showed nuclear dots (Cajal bodies) and cytoplasmic staining. Only 1 serum was weakly positive on Western blotting of SMN, suggesting that these sera mainly recognize native molecule or quaternary structure. All 3 patients
were white women with PM, an interesting finding, since deletion or mutation of SMN is known to cause spinal muscular atrophy.\n\nConclusion. SMN complex was identified as a new Cajal body autoantigen recognized by sera from white patients selleck kinase inhibitor with PM. The biologic and clinical significance of anti-SMN autoantibodies will need to be clarified.”
“Background: Historical outcomes in anaplastic thyroid carcinoma (ATC) are poor, with a median survival of only 5 months and <20% of patients surviving 1 year from diagnosis. We hypothesized that survival in newly diagnosed patients with stages IVA and IVB locoregionally confined ATC click here might be improved by utilizing an aggressive therapeutic approach, prioritizing both the eradication of disease in the neck and preemptive treatment of occult metastatic disease.\n\nMethods: Between January 1, 2003, and December 31, 2007, 25 new
ATC patients were evaluated at our institution. Of these 25 patients, 10 (40%) had metastatic disease at diagnosis and therefore underwent palliative treatment, whereas 5 (20%) had regionally confined disease and desired treatment at their local medical facilities. The remaining 10 consecutive patients (40%) had regionally confined ATC and elected aggressive therapy combining individualized surgery (where feasible), intensity-modulated
radiation therapy (IMRT), and radiosensitizing + adjuvant chemotherapy intending four cycles of docetaxel + doxorubicin. Outcomes were assessed on an intention to treat basis.\n\nResults: There were no deaths from therapy, but JQ-EZ-05 nmr hospitalization was required in two patients (20%) because of treatment-related adverse events. Five patients (50%) are alive and cancer-free, all having been followed >32 months (range: 32-89 months; median: 44 months) with a median overall Kaplan-Meier survival of 60 months. Overall survival at 1 and 2 years was 70% and 60%, respectively, compared to <20% historical survival at 1 year in analogous patients previously treated with surgery and conventional postoperative radiation at our and other institutions.\n\nConclusions: Although based upon a small series of consecutively treated patients, an aggressive approach combining IMRT and radiosensitizing plus adjuvant chemotherapy appears to improve outcomes, including survival in stages IVA and IVB regionally confined ATC, but remains of uncertain benefit in patients with stage IVC (metastatic) disease. Also uncertain is the optimal chemotherapy regimen to use in conjunction with DART.
