Study to Assess Perfusion and Patient Satisfaction in Nipple-Areola Mastectomy With Immediate Reconstruction (NASSM)

March 20, 2018 updated by: Washington University School of Medicine

A Prospective Randomized Trial to Assess Perfusion and Patient Satisfaction in Nipple-Areola Mastectomy With Immediate Reconstruction

The investigators hypothesize that nipple-areola skin sparing mastectomy (NASSM) performed through an inframammary incision has a superior blood supply relative to a lateral oblique incision. Moreover, by minimizing complications and optimizing aesthetic outcomes, the investigators believe it will be associated with significantly higher patient reported outcome scores. The addition of information gained by use of intraoperative laser-assisted fluorescent angiography (measured with the Spy Elite imaging device) will reduce complication rates by directing intraoperative resection of ischemic tissue and limiting the volume of immediate implant placement in instances where real time imaging would suggest compromised perfusion. These quantifiable, objective measures will justify the use of NASSM and immediate implant placement coupled with intraoperative laser-assisted fluorescent angiography in prosthetic based breast reconstruction despite longer operative times.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  • Patient must be scheduled to undergo either a single or bilateral elective nipple-areola skin sparing mastectomy (NASSM) procedure with planned immediate reconstruction.
  • Patient must be 18 years of age or older.
  • Karnofsky Performance Scale of at least 80%.
  • Patient must be able to understand and willing to sign a written informed consent document.

Exclusion Criteria:

  • Cognitive impairment.
  • BMI < 18 or > 35
  • Breast >800 grams or <100 grams in predicted weight. "Breast" includes the breast tissue and in cases where the patient already has cosmetic breast implants, the additional breast implant mass. The sum total must be >100 g and <800 g.
  • History of radiation to the chest wall or breast being studied
  • Patients who have a history of allergy to iodides or iodinated contrast agents
  • Surgeon's opinion at the time of surgery that the subject's well-being would be compromised (e.g. significant comorbidities, intraoperative findings of a higher stage cancer or other independent acute health problems). If the contralateral breast is undergoing a nipple-sparing mastectomy with reconstruction as well, then the contralateral breast can be studied so long as there is no compromise to any element of their care.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Original Preoperative Blood Supply (Perfusion) Post Nipple Sparing Mastectomy
Time Frame: At the time of surgery (day 1)
  • Laser-assisted fluorescent angiography via the Spy Elite imaging device will be utilized to capture this data during mastectomy and immediate breast reconstruction. Standard postoperative patient follow up will assess for perfusion.
  • The Spy device quantifies perfusion by measuring relative fluorescence of indocyanine green bound to plasma proteins. This produces an intensity value of 0-255 based on an 8-bit greyscale. The investigators measured this value preoperatively when measured and compared to the post-intervention measurement. The device can calculate the cumulative intensity of a defined region of interest which the investigators categorized as the lateral, lower, medial, or nipple-areola region of the breast. The investigators also evaluated the cumulative value of these areas in total. Rate of perfusion was simply this value over time (90 seconds).
At the time of surgery (day 1)
Percentage of Original Preoperative Blood Supply (Perfusion) Post Reconstruction

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Breast Q Score
Time Frame: Up to 3 months post permanent implant placement
-The BREAST-Q is a previously validated instrument which measures patient reported outcomes. It has several iterations including the one utilized here which is specific for implant-based breast reconstruction. Each of its 6 domains generates a Q-score from 0 (lowest) to 100 (highest). A higher number indicates a higher satisfaction or better quality of life than a lower number. Based on answers to the questions, each individual will generate a whole number score for each domain. The patient can be sampled preoperatively and postoperatively as well as over time to calculate the impact of intervention and time on this value. Q-scores are calculated for each domain, and the investigators report a mean value based on data from an entire cohort for the particular domain. Domains include evaluation of overall satisfaction with breasts, physical well being, sexual well being, as well as satisfaction with office staff, information provided, and the provider.
