What is Oncoplastic Surgery?
• Oncoplastic surgery (OPS):
Resection of the tumor
and reconstruction of the defect
using plastic surgical techniques
The term “Oncoplastic surgery” was introduced in 1993 and published in 1994 by Werner P. Audretsch et al.
Does not mean small incision, small Vol resection, nor microinvasive surgery
Oncologic outcomes must
NEVER be compromised
by cosmesis
![Page 4: Evidence-based indication of Oncoplastic Breast Surgerygbcc.kr/upload/Wonshik Han.pdf · (Tennis-Racket) LOQ J-mammoplasty Lower pole inverted-T mammoplasty with a superior pedicle](https://reader035.fdocuments.net/reader035/viewer/2022070113/605e9c84f6627f49aa138be2/html5/thumbnails/4.jpg)
Breast Surgeon’s Dilemma: Radicalityvs. Cosmesis
“You can have your cake and eat it too with OPS”
![Page 5: Evidence-based indication of Oncoplastic Breast Surgerygbcc.kr/upload/Wonshik Han.pdf · (Tennis-Racket) LOQ J-mammoplasty Lower pole inverted-T mammoplasty with a superior pedicle](https://reader035.fdocuments.net/reader035/viewer/2022070113/605e9c84f6627f49aa138be2/html5/thumbnails/5.jpg)
Advantages Disadvantages
Resection of larger breast
volumes
Longer duration of surgery
Wider free margins More visible scars
Less re-excision, Less conversion
to 2’ mastectomy
Higher complication rate possible
Better cosmetic results Experienced breast surgeon or
plastic surgeon is necessary
Extension of BCS indication
Advantages and disadvantages of OPS

Effect of cosmetic outcome on quality of life
after breast cancer surgery
• BCS (N=485), TM (N=87), TM with immed recon
(N=46) in SNUH
• BCCT.core, Specialists panel, Pt’s body image
perception (body image scale)
• General QoL was not associated with objectively
measured cosmetic results
• Self-perception of body image seems to be more
important for QoL

OPS, self perception of cosmetic outcome,
and QoL
OPS doesn’t increase patients’ self perception of esthetic outcome
QoL is dependent on self perception of body image, not
surgeon’s measurement

First international consensus conference on standardization
of oncoplastic breast conserving surgery (in Basel)
• Most panels agreed Clough’s classification is useful
in clinical practice for indicating, planning, and
performing the procedure
• Hoffmann classification was recommended for
operating report and use for clinical research
• Basel classification useful for operative report and
for distinguishing BCS from OPS

Prospective trial investigating the association
between cosmetic result and quality of life
• N=400 in SNUH since 2016 (290 enrolled now)
• Only DCIS (to avoid the effect of adj therapy)
• BCS (with or without OPS) and TM with immediate
recon
• Patients interview and photo (preop and postop
1yr)
• BCCT.core and panel assessment for cosmetic result
• Breast-Q for QoL assessment
![Page 33: Evidence-based indication of Oncoplastic Breast Surgerygbcc.kr/upload/Wonshik Han.pdf · (Tennis-Racket) LOQ J-mammoplasty Lower pole inverted-T mammoplasty with a superior pedicle](https://reader035.fdocuments.net/reader035/viewer/2022070113/605e9c84f6627f49aa138be2/html5/thumbnails/33.jpg)
Summary
1. OPS improves objectively measured esthetic outcome, but
uncertain for patients perceived body image and QoL
2. OPS might reduce reoperation rate for positive resection
margins
3. OPS might not reduce local recurrence rate
4. OPS broaden the indication of BCS (large or multifocal
tumors)
5. OPS based on tumour location and a quadrant-per-quadrant
atlas (Clough’s classification) is useful in clinical practice
6. Now the number of oncoplastic BCS is decreasing in Korea
due to increased use of neoadjuvant therapy and increased
use of mastectomy and immediate reconstruction
7. We need more high level evidences, more tools for
assessment, and more standardization of the OPS procedures
