Combined intralesional Bacille Calmette-Guérin (BCG) and topical imiquimod for in-transit melanoma.

The introduction of numerous immunotherapeutic agents into the clinical arena has allowed the long-time promise of immunotherapy to begin to become reality. Intralesional immunotherapy has demonstrated activity in multiple tumor types, and as the number of locally applicable agents has increased, so has the opportunity for therapeutic combinations. Both intralesional Bacille Calmette-Guérin (ILBCG) and topical 5% imiquimod cream have been used as single agents for the treatment of dermal/subcutaneous lymphatic metastases or in-transit melanoma, but the combination has not previously been reported.

Preoperative imaging of pulmonary metastases in patients with melanoma: implications for minimally invasive techniques.

Hypothesis: Preoperative imaging underestimates the number of pulmonary melanoma metastases. Although thoracoscopic resection is less invasive than resection via thoracotomy, it does not allow manual palpation of the lung to identify any metastases not visible on the preoperative scan or at the time of resection.

Design: Retrospective review of a prospectively maintained database.

Should quality measures for lymph node dissection in colon cancer be extrapolated to rectal cancer?

Background: A minimum of 12 lymph nodes has been endorsed as a quality measure to confirm node-negative colon cancer, but its relevance to early-stage rectal cancer is unclear.

Methods: Patients with stage I or II rectal cancer from the Surveillance, Epidemiology and End Results tumor registries from 1998 to 2002 were identified. Patients were grouped by the number of lymph nodes sampled.

Epitrochlear sentinel lymph nodes in melanoma: interval or independent?

Most primary melanomas on the distal upper extremity metastasize to a sentinel lymph node (SLN) in the axillary basin, but occasionally a primary melanoma will drain to the epitrochlear basin. The relationship between tumor-draining axillary and epitrochlear SLNs is unclear. We hypothesize that the epitrochlear SLN functions in an interval manner with the axillary lymph node basin.
