Current Concepts in the Diagnosis and Management of Small-Cell Lung Cancer
October 15th 2010Despite a decreasing incidence in the United States, small-cell lung cancer (SCLC) remains a major clinical problem, with approximately 30,000 new cases each year. The diagnosis of SCLC is usually not difficult. The Veterans Administration Lung Study Group (VALSG) staging system is less accurate than the American Joint Committee of Cancer tumor-node-metastasis (TNM) system (7th edition) at predicting survival in SCLC, especially in lower stage disease. Surgery has not played a major part in the management of SCLC, but emerging data suggest that resection may have a role in earlier stage disease. While the frontline treatment of SCLC has not changed significantly in the past decade, newer agents that are currently being investigated provide hope for better treatment of relapsed/refractory disease for the future.
Multiple Myeloma in the Elderly: When to Treat, When to Go to Transplant
October 15th 2010Until recently, standard treatment of multiple myeloma (MM) in elderly patients who were not candidates for autologous stem cell transplantation was with the combination of melphalan plus prednisone (MP). Novel agents (thalidomide, lenalidomide, bortezomib) are dramatically changing frontline therapy of MM. Randomized studies have shown the superiority of adding one novel agent to MP, either thalidomide (MPT) or bortezomib (MPV). The combination of lenalidomide with low doses of dexamethasone is another attractive alternative. Recent results show that maintenance therapy with low-dose lenalidomide may prolong progression-free survival. The objective of these improved treatment regimens should be to achieve complete response, as in younger patients. However, toxicity is a significant concern, and doses of thalidomide and of myelotoxic agents should be reduced in patients who are older than 75 years or who have poor performance status. Weekly bortezomib appears to induce severe peripheral neuropathy less frequently than the same agent administered twice weekly. Autologous stem cell transplantation is feasible in selected fit patients over 65 years of age, and its results are improved by the addition of novel agents before and after high-dose therapy. However, considering the progress in non-intensive therapy, autologous transplantation should not currently be offered to elderly patients outside of a clinical trial.
The Treatment of Elderly Patients With Multiple Myeloma: Is More Better?
October 15th 2010The variety of treatment options available to patients of all ages who have multiple myeloma has improved considerably in the past decade. However, elderly patients have benefited more than patients of other ages. Because elderly patients, as a group, are usually not offered autologous stem cell transplant (ASCT) as a treatment option, they have been unable to benefit from the wide application of this technique, first introduced in the late 1980s. In the past 8 years, however, thalidomide, bortezomib, and very recently lenalidomide, when combined with conventional doses of alkylators and corticosteroids, have produced marked improvements in progression-free survival (PFS) and overall survival (OS) in elderly patients. Harousseau has thoroughly reviewed the important studies documenting these benefits for this population.
