Local recurrence in breast cancer: implications for systemic disease.

Background: Recurrence in breast carcinoma follows a pattern of growth marked by local, regional, or widespread dissemination. Local recurrence may be the harbinger of systemic disease or failure of local control. Delineation of these processes may have implications in treatment.

The value of symptom directed evaluation in the surveillance for recurrence of carcinoma of the breast.

Specific postoperative tests used to diagnose recurrent carcinoma of the breast were evaluated for their ability to have an impact on the over-all course of the disease. Sixty-four patients with recurrent or new contralateral primary disease were divided into two groups based on the method of diagnosis. Those patients with a new complaint at an interval between scheduled follow-up visits and who went on to have tests to document a recurrence were categorized as interval follow-up.

A prospective, randomized evaluation of the treatment of colorectal cancer metastatic to the liver.

Over a 4-year period (1982 to 1986), 91 patients with solitary or multiple metastases from colorectal cancer were stratified, based on findings at laparotomy, to one of three groups and then prospectively randomized to one of two treatment arms within each group. Group A patients had solitary resectable metastases, group B patients had multiple, resectable metastases, and group C patients had multiple, unresectable metastases. Patients were randomized to one of two treatment arms within a group: group A-arm A1: resection only, arm A2: resection and continuous hepatic artery infusion (CHAI) of fluorodeoxyuridine (FUdR); group B-arm B1: resection and CHAI, arm B2: CHAI only; group C-arm C1: CHAI, arm C2: systemic fluorouracil followed by CHAI.

A prospective, randomized double-blind study of the use of antibiotics at the time of mastectomy.

The ability of perioperative cefazolin to reduce the incidence of postoperative wound infection in patients undergoing ablative surgical treatment for carcinoma of the breast was tested in this prospective, randomized, double-blinded study. From May 1983 until December 1985, 118 women were divided into two groups at random. Group 1 consisted of 59 patients and received cefazolin and group 2 was made up of 59 patients who received a placebo.

Central venous thrombosis related to the silastic Hickman-Broviac catheter in an oncologic population.

The use of subcutaneously implanted, Dacron cuffed, central venous silastic catheters (Hickman/Broviac catheter [HC/BC]) has not eliminated catheter related-central venous thrombosis (CR-CVT). HC/BC related CR-CVT was identified and followed in 15 oncology patients. Median time period to CR-CVT was 155 days (range 15-638).
