Circulating DNA microsatellites: molecular determinants of response to biochemotherapy in patients with metastatic melanoma.
Although biochemotherapy appears to be a promising treatment for metastatic melanoma, its impact remains unpredictable. Microsatellite markers for loss of heterozygosity (LOH) appear to have prognostic significance when identified in primary tumors and serum and/or plasma from cancer patients. However, their association with response to systemic therapy has yet to be assessed. To determine whet...
متن کاملMetastatic melanoma: chemotherapy to biochemotherapy.
BACKGROUND Single-agent or combination chemotherapy regimens have not impacted the short median survival of patients with metastatic melanoma, and complete or durable responses are rare. Biologic response modifiers (interferon and interleukin-2) have produced durable remissions in a small cohort of patients, and phase II trials of biochemotherapy suggest more benefit. METHODS The authors retr...
متن کاملCirculating tumor DNA to monitor treatment response and detect acquired resistance in patients with metastatic melanoma
Repeat tumor biopsies to study genomic changes during therapy are difficult, invasive and data are confounded by tumoral heterogeneity. The analysis of circulating tumor DNA (ctDNA) can provide a non-invasive approach to assess prognosis and the genetic evolution of tumors in response to therapy. Mutation-specific droplet digital PCR was used to measure plasma concentrations of oncogenic BRAF a...
متن کاملPatients' perceptions of fatigue in response to biochemotherapy for metastatic melanoma: a preliminary study.
PURPOSE/OBJECTIVES To explore patients' perceptions of fatigue in response to biochemotherapy treatment for metastatic melanoma. DESIGN A descriptive-correlational, cross-sectional study. SETTING A cancer center in the midwestern United States. SAMPLE 12 adult patients between the ages of 28-70 who received at least one cycle of biochemotherapy treatment for metastatic melanoma (stages II...
متن کاملUtility of circulating B-RAF DNA mutation in serum for monitoring melanoma patients receiving biochemotherapy.
PURPOSE Somatic B-RAF gene mutation has been identified in many malignancies and detected at a high frequency in cutaneous malignant melanoma. However, the significance of the B-RAF mutation (B-RAFmt) in terms of its prognostic and predictive capabilities for treatment response or disease outcome is not known. We hypothesized that circulating serum B-RAFmt (B-RAFsmt) at V600E, detected in serum...
