  Purpose

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.

Primary Outcome Measures:
  • Post-operative pain at 1 and at 7-10 days after mastectomy [ Time Frame: 7-10 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Number of acetaminophen/oxycodone tablets taken [ Time Frame: 7-10 days after surgery ] [ Designated as safety issue: No ]
  • Total time of operation from breast incision to completion of wound closure [ Time Frame: Day of surgery ] [ Designated as safety issue: No ]
  • Time of operation from first incision to completion of both superior and inferior skin flaps [ Time Frame: Day of surgery ] [ Designated as safety issue: No ]
  • Estimated blood loss [ Time Frame: Day of surgery ] [ Designated as safety issue: No ]
  • Number of days the Jackson-Pratt drain is left in place with wound drainage > 30 mL/24 hours [ Time Frame: 7-10 days after surgery ] [ Designated as safety issue: No ]
  • Wound complications (skin necrosis, hematoma, cellulitis, abscess, and seroma) occurring up to and 10 days post-operatively [ Time Frame: Up to 10 days after surgery ] [ Designated as safety issue: No ]

Estimated Enrollment: 74
Study Start Date: October 2008
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Group 1
Patients undergo standard mastectomy.
Procedure: therapeutic conventional surgery
Patients undergo tumescent or standard mastectomy
Group 2
Patients undergo tumescent mastectomy.
Procedure: therapeutic conventional surgery
Patients undergo tumescent or standard mastectomy

Detailed Description:

OBJECTIVES:

Primary

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

Secondary

  • 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).
