Skeletal metastases are a frequent site of involvement for patients with metastatic nonsmall cell lung cancer. Skeletal metastases may result in skeletal-related events. These complications typically result in significant morbidity for patients and substantially increase the economic costs associated with the treatment of patients with skeletal metastases. The management of skeletal metastases in patients with nonsmall cell lung cancer is evolving as improved treatments and monitoring become available. ⋯ The management of skeletal metastases from nonsmall cell lung cancer is evolving as biochemical markers may be used to guide the treatment of these patients. Newer targeted therapies are also in development and may be used in the treatment of patients with skeletal metastases.

Lymphatic mapping and sentinel lymph node biopsy have been established as definitive procedures for the staging of cutaneous melanoma. Large-scale studies that have been recently conducted and that are ongoing suggest a therapeutic role for lymphatic mapping/sentinel node biopsy in the management and prognosis of melanoma patients with early lymph node metastases. ⋯ There is increasing evidence for the efficacy of lymphatic mapping and sentinel lymph node biopsy in predicting prognosis, reducing the morbidity traditionally associated with regional lymph node dissection and increasing survival in subgroups of patients with cutaneous melanoma. Further study is needed to determine the role of the immune system in the spread of nodal metastases and the role of immunomodulatory therapy to prevent or possibly even reverse nodal metastases.
