Lymphoepithelioma-Like Carcinoma of the Urinary Bladder
A 65-year-old woman presented to a local emergency department complaining of right flank pain that had worsened over the past 10 days. A CT scan of the abdomen and pelvis showed intravesical tumors of the urinary bladder.
Locoregional Recurrence of an HPV-Positive Squamous Cell Carcinoma of the Head and Neck
Locoregional recurrences are a major source of morbidity and mortality for patients with squamous cell carcinomas of the head and neck (HNSCC).

The patient is an otherwise healthy male transferred from an outside hospital with a newly diagnosed melanoma from an unknown primary presenting as a large, left axillary mass.
Emerging Role of EGFR-Targeted Therapies and Radiation in Head and Neck Cancer
December 1st 2004The treatment of head and neck cancer has been at the forefront ofnovel therapeutic paradigms. The introduction of drugs that interactwith selective biologic pathways in the cancer cell has generated considerableattention recently. A wide variety of new compounds that attemptto target growth-signaling pathways have been introduced intothe clinic. A majority of studies in the clinic have focused on epidermalgrowth factor receptor (EGFR) antagonists, but future studies will likelybuild upon or complement this strategy with agents that target angiogenicor cell-cycle pathways. EGFR activation promotes a multitude ofimportant signaling pathways associated with cancer development andprogression, and importantly, resistance to radiation. Since radiationtherapy plays an integral role in managing head and neck squamouscell cancer (HNSCC), inhibiting the EGFR pathway might improveour efforts at cancer cure. The challenge now is to understand whenthe application of these EGFR inhibitors is relevant to an individualpatient and how or when these drugs should be combined with radiationor chemotherapy. Are there molecular markers available to determinewho will respond to EGFR inhibitors and who should be treatedwith alternative approaches? What are the mechanisms behind intrinsicor acquired resistance to targeted agents, and how do we preventthis problem? We need to formulate integrated laboratory/clinicalresearch programs that address these important issues.
A 72-Year-Old Man With Prostate Cancer
The patient, L.E., is a 72-year-old white male who has been under our care for 10 years. He initially presented to our clinic in 1992, with a diagnosis of localized prostate cancer.
