Brief Summary:

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.

Condition or disease Intervention/treatment
Breast Cancer Pain Perioperative/Postoperative Complications Procedure: therapeutic conventional surgery

Detailed Description:



  • 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).

Group/Cohort Intervention/treatment
Group 1

Procedure: therapeutic conventional surgery
Patients undergo tumescent or standard mastectomy
Group 2

Primary Outcome Measures :
  1. Post-operative pain at 1 and at 7-10 days after mastectomy [ Time Frame: 7-10 days ]

Secondary Outcome Measures :
  1. Number of acetaminophen/oxycodone tablets taken [ Time Frame: 7-10 days after surgery ]
  2. Total time of operation from breast incision to completion of wound closure [ Time Frame: Day of surgery ]
  3. Time of operation from first incision to completion of both superior and inferior skin flaps [ Time Frame: Day of surgery ]
  4. Estimated blood loss [ Time Frame: Day of surgery ]
  5. 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 ]
  6. 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 ]
