Pain After Tumescent Mastectomy or Standard Mastectomy in Women With Stage I, Stage II, or Stage III Breast Cancer

2014-08-26 22:23:43 | BioPortfolio


RATIONALE: New surgery techniques may lessen pain after breast surgery. It is not yet known whether tumescent mastectomy or standard mastectomy results in less pain in women with breast cancer.

PURPOSE: This clinical trial is studying pain after tumescent mastectomy compared with pain after standard mastectomy in women with stage I, stage II, or stage III breast cancer.




- To compare post-operative pain after tumescent vs standard mastectomy in women with stage I-III breast cancer.


- To compare the total time of operation from incision to completion of wound closure.

- To compare the time of operation from first incision to completion of skin flaps.

- To compare the total estimated blood loss.

- To compare the number of days the Jackson-Pratt drain is left in place under skin flaps with wound drainage > 30 mL/24 hours.

- To compare the incidence of wound complications such as skin necrosis, hematoma, cellulitis, abscess, and seroma between groups.

OUTLINE: Patients are grouped according to which surgeon provided their evaluation and treatment recommendations.

- Group 1: Patients undergo standard mastectomy.

- Group 2: Patients undergo tumescent mastectomy. All patients receive standardized post-operative pain management comprising morphine sulfate for analgesia or an equivalent dose of hydromorphone hydrochloride for 24 hours following surgery. Patients then receive 1-2 oral acetaminophen/oxycodone hydrochloride combination tablets (or a comparable amount of another narcotic/acetaminophen combination) every 6 hours as needed. Pain is assessed using the Short-form McGill Pain Questionnaire (SF-MPQ).

Medical and Biotech [MESH] Definitions

Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.

A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)

Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.

Tumors or cancer of the human BREAST.

The phosphoprotein encoded by the BRCA1 gene (GENE, BRCA1). In normal cells the BRCA1 protein is localized in the nucleus, whereas in the majority of breast cancer cell lines and in malignant pleural effusions from breast cancer patients, it is localized mainly in the cytoplasm. (Science 1995;270(5237):713,789-91)
