Receptor changes in metachronous breast tumors--our experience of 10 years.

Introduction: Patients with primary breast cancer (PBC) are at 2 to 6 times higher risk for developing synchronous and metachronous breast cancer (MBC). The pathology and behavior of MBC still remains unclear.

Methods: We reviewed the charts of 108 women with MBC at our hospital over the past 10 years.

Prolonged (longer than 3 hours) laparoscopic cholecystectomy: reasons and results.

For the experienced surgeon, the average operative time for a laparoscopic cholecystectomy is less than 1 hour. There has been no study documenting the causes and results of prolonged (longer than 3 hours) surgery. A retrospective study was done of patients who underwent cholecystectomy between January 2003 and December 2007.

Review of third and fourth re-excision for narrow or positive margins of invasive and intraductal carcinoma.

The trend in breast surgery has shifted toward breast conservation. We reviewed our third and fourth breast re-excision cases, with an analysis of various factors used in making this decision. A retrospective analysis identified 585 patients who underwent re-excision surgery for positive or close margins of invasive carcinoma or ductal carcinoma in situ (DCIS).

Gastrointestinal carcinoids: an increasing incidence of rectal distribution.

Carcinoid tumors are slow-growing and usually become symptomatic late in the course of the disease. We evaluated our 10-year experience in the management of GI carcinoid tumors. The records of 133 patients with GI carcinoids were reviewed.

Prevalence and management of gastrointestinal stromal tumors.

The prevalence and characteristics of patients with confirmed gastrointestinal stromal tumor (GIST) in a community hospital over a 6-year period are described. Our objective was to communicate our experience managing this rare tumor of the gastrointestinal tract. A retrospective chart review was performed.
