Study information

Scientific title

Does intra­operative use of the MarginProbe device reduce the need for further re­-excision procedures after conservation surgery for breast cancer?


Study hypothesis

Study aims:
1. To determine if intraoperative margin assessment after excision of a cancer reduces second operations (re-excision or mastectomy), compared to standard surgical practice by 9 months after primary surgery
2. To determine if the use of the MarginProbe device, after surgical tumour excision and tissue specimen radiography of a breast cancer, reduces rates of further surgical re-excision operations (re-excision or mastectomy), when compared to control/standard practice (whereby the wound is closed after radiography showing clear margins)

Breast cancer


All surgeons will perform standard wide local excision (BCS) using localisation of the lesion for impalpable lesions where required. Randomization will take place immediately after the main ex-vivo lumpectomy specimen has been excised, oriented, border marked, inspected, palpated and additional cavity shavings (per visual inspection, palpation and radiology) performed. Patients will be randomised in theatre, by call to the MAHSC CTU, to either standard procedure alone or standard procedure with the use of the MarginProbe device:

Device Arm: Measurements shall be taken with the MarginProbe on the outer final surface of each margin. Once the device has been applied to outer final surface of all margins, all margins with one or more positive readings on it should be shaved from the cavity. The procedure will then be concluded in the routine practice.

Control Arm: The procedure will be concluded in the routine practice.

MarginProbe use starts and ends during the primary lumpectomy procedure. Thus, patient management differs between the two study arms only during the procedure. Following the procedure, pathological assessment and any other patient management aspects are identical for both study arms. The follow-up period for both study arms is 9 months. Follow up visits (month 1, 6 and 9): FACT B +4, HADS and EQ5D Questionnaires and Patient Diary Cards Administered. Photographs for cosmesis completed at baseline and 9 months.

Intervention type



Drug names

Primary outcome measure

1. Reduction rates in re-excision procedures are determined by review of pathology reports for all participants to record subsequent surgeries at 9 months post initial surgery
2. Total number of re-excision procedures is determined by review of patient notes, clinical data and pathology reports at 9 months post initial surgery
3. Excision margins determined by review of pathology reports at 9 months post initial surgery

Secondary outcome measures

1. Quality of life measured by using validated self-completion disease specific and generic instruments, FACT-B, HADS, health-related utility (EQ5D) and the body image scale of SABIS administered at baseline (pre-surgery) and postal follow-up at 1, 3 and 9 months post-surgery
2. Cosmetic outcome assessment will be performed by two objective evaluators blinded to arm assignment based on pictures taken under standardized photographic conditions. The scoring will be performed using the validated 4-point Harvard scale. Pictures will be taken at baseline and 9 months post-surgery.
3. Impact of margin assessment on patients and carers will be measured by questionnaires assessing experiences and satisfaction and semi structured interviews exploring concerns, expectations, preferences, satisfaction and awareness of procedural differences. This will be a qualitative sub study of the main trial and timescales are dependent on when this is set up.
4. Clinical and cost effectiveness measured by review of hospital in-patient records and patient diary cards at 1, 3 and 9 months
