Eccrine Carcinoma With an Unknown Primary: Managing Occult Cancer Through Multidisciplinary Tumor Board Collaboration.

Eccrine carcinomas are rare cutaneous cancers that tend to be locally aggressive. Here we report a rare case of a mucinous eccrine carcinoma presenting in axillary lymph nodes without an identifiable primary lesion. This is a 69-year-old male with a past medical history of benign prostatic hyperplasia, melanoma, basal cell carcinoma, hypercholesterolemia, hypertension, and arthritis who was found to have an elevated prostate-specific antigen.

Patient-reported acute gastrointestinal toxicity in men receiving 3-dimensional conformal radiation therapy for prostate cancer with or without neoadjuvant androgen suppression therapy.

Objective: To investigate the impact of 2 months of neoadjuvant and 2 months of concurrent hormonal therapy on the acute gastrointestinal (GI) toxicities associated with 3-dimensional conformal radiation therapy (3D-CRT) for prostate adenocarcinoma.

Methods: The study cohort consisted of 80 men who underwent 3D-CRT with (n=40) or without (n=40) neoadjuvant and concurrent hormonal therapy. Computerized tomography-based planning occurred after neoadjuvant hormonal therapy.

Limitations in the use of serum prostate specific antigen levels to monitor patients after treatment for prostate cancer.

Purpose: We reviewed the literature to help clarify the benefits and/or hazards associated with monitoring serum prostate specific antigen (PSA) after treatment with surgery or radiation therapy (RT) for nonmetastatic prostate cancer.

Materials And Methods: A search was performed for 1990 to 2004 using the MEDLINE database, CancerLit database and reference lists of relevant studies to obtain articles addressing the use of serum PSA to follow patients after treatment for prostate cancer. Studies were reviewed to determine 1) if serial PSA monitoring provides an early and accurate surrogate assessment of cancer cure or treatment failure, 2) if any pattern in the PSA profile after treatment provides conclusive evidence of early local vs systemic failure, 3) the magnitude of the lead time to clinical failure that serial PSA monitoring may provide and 4) if the early identification of biochemical failure (BF) with earlier intervention improves outcome.

Prognosis after local recurrence after conservative surgery and radiation for early-stage breast cancer.

Purpose: To determine the long-term prognosis of patients who develop a local recurrence (LR) after conservative surgery (CS) and radiation therapy (RT) for early-stage invasive breast cancer.

Methods And Materials: Between 1970 and 1987, 2102 patients with clinical Stage I-II breast cancer were treated with CS+RT. LR was defined as any recurrence within the ipsilateral breast with or without simultaneous regional nodal or distant metastasis.
