[Oncoplastic surgery of the breast: a combination of oncological and plastic surgery]

The term oncoplastic surgery refers to surgery on the basis of oncological principles during which the techniques of plastic surgery are used, mostly for reconstructive and cosmetic reasons. The advantage ofoncoplastic surgery for breast cancer is the possibility of performing a wider excision of the tumour with a good cosmetic result. Oncoplastic surgery is a broad concept that can be used for several different combinations of oncological surgery and plastic surgery: mastectomy and immediate reconstruction of the breast, partial mastectomy and reconstruction, excision of the tumour by reduction mammoplasty, and tumour excision followed by remodelling mammoplasty. Oncoplastic surgery requires careful preoperative planning, which is essential in all forms of breast-sparing surgery. Oncoplastic principles can easily be applied to basic breast-sparing surgery, but one can also choose to increase the possibilities of breast surgery by organising good cooperation between the oncological surgeon and the plastic surgeon.

Clinical experience of prophylactic mastectomy followed by immediate breast reconstruction in women at hereditary risk of breast cancer (HB(O)C) or a proven BRCA1 and BRCA2 germ-line mutation

AIM

Women with a proven BRCA1 or BRCA2 germ-line mutation or with a 50% risk of carrying the mutation, have an increased risk of breast cancer. Regular surveillance, chemoprevention or prophylactic mastectomy (PM) are options to detect breast cancer at an early stage or to reduce the risk. We describe the management of women who have opted for PM, the postoperative complications of PM, especially in combination with immediate breast reconstruction (IBR), and the oncological follow-up.

METHODS

The medical records of all women who underwent a PM from December 1993 to December 1999 have been reviewed with respect to management, patient characteristics, complications and oncological follow-up.

RESULTS

During the study period 112 women with a median age of 38.8 years opted for a PM: 76 were germline mutation carriers. After PM, 79 women without breast or ovarian cancer in their medical history, were free of disease after 2.5 years (median). Before PM, 29 women had been treated for breast cancer, 3.9 years (median) previously; 5 of these women had developed metastatic disease by the last consultation. Before PM, 2 patients had been treated for DCIS and 2 patients for ovarian cancer. Four DCIS were found; none of these women had evidence of disease 4.0 years (median) after PM. In 59 women laparoscopic prophylactic bilateral oophorectomy (PBO) was performed; 36 simultaneously with PM and 23 separately. A total of 103 women (92%) opted for IBR. After PM, the complication rate for IBR was 21%: 11% within 6 weeks and 10% at long-term follow-up (median 3.5) after PM, including the removal of 10 prostheses.

CONCLUSIONS

Women with an increased risk of breast cancer due to a genetic predisposition should be adequately informed about the different treatment options in the setting of a multidisciplinary approach. PM can simultaneously be combined with PBO and IBR. IBR can facilitate the decision to undergo a PM. PM followed by IBR has an acceptable complication rate.

A prospective study on silicone breast implants and the silicone-related symptom complex

This cohort study prospectively evaluated the prevalence of the silicone-related symptom complex (SRSC) in relation to antinuclear antibodies (ANA) and magnetic resonance imaging (MRI) of silicone breast implants (SBI) 1 year after implantation. A total of 57 women undergoing mastectomy followed by immediate breast reconstruction (IBR) and SBI between March 1995 and March 1997 at the University Hospital Rotterdam/Daniel den Hoed Cancer Centre, were prospectively evaluated. Just before and 1 year after IBR the sera of these women were tested for the presence of ANA and they were screened for the prevalence of SRSC-related symptoms by questionnaire. All prostheses were evaluated by MRI 1 month and 1 year after IBR. Just before operation 11% of the women had a Sjögren score of more than 2, whereas 30% had such a score 1 year after IBR ( P = 0.01). One year postoperatively women had significantly more RA/Raynaud-related complaints: 21% preoperatively versus 40% 1 year after IBR ( P = 0.03). Within the undefined complaints-related group 19% had a score of 2 or more preoperatively and 33% 1 year after IBR ( P = 0.09). There were no new cases of ANA positivity 1 year after IBR. The linguine sign was seen by MRI in three implants: one 1 month after IBR and two 1 year after IBR. There was no relation to changes in SRSC expression and these MRI findings. In conclusion, 1 year after SBI implantation women had more SRSC-related complaints, especially Sjögren's and RA/Raynaud's. Moreover there was no correlation between elevated SRSC expression and changes in the presence of ANA or changes in MRI of the SBI 1 year after IBR.

Morbidity of immediate breast reconstruction (IBR) after mastectomy by a subpectorally placed silicone prosthesis: the adverse effect of radiotherapy

AIMS

This study evaluates the incidence of local complications after immediate breast reconstruction (IBR) following mastectomy with a subpectorally placed silicone prosthesis, with emphasis on the effect of radiation treatment on IBR.

METHODS

The medical records of 100 women, who underwent a mastectomy followed by IBR with a subpectorally placed silicone prosthesis at the University Hospital Rotterdam/Daniel den Hoed Cancer Center, between March 1990 and March 1995, were reviewed. Thirteen prostheses were implanted prior to radiation treatment, and 15 prostheses were implanted after irradiation of the chest wall.

RESULTS

Early complications were seen in 15% of the IBR and were more often in irradiated women. At long-term follow-up, the most common complication was capsular contracture (21%). This occurred significantly more around prostheses placed in a previously irradiated area (P<0.0005), or which were irradiated after IBR (P=0.001). Loss of prosthesis was seen in 11 cases, and was significantly (P<0.005) more in irradiated women (n=5; 18%) compared to women who were not irradiated (n=6; 7%).

CONCLUSIONS

Complications after IBR with a silicone prosthesis were more common in women who were treated with radiotherapy prior to or after IBR following mastectomy than in women who were not irradiated. In particular, capsular contracture around a prosthesis placed in a previously irradiated area was significantly increased. The use of musculocutaneous flaps, such as the transverse rectus abdominis muscle or latissimus dorsi flap, is preferable for reconstruction of previously irradiated breasts. There is no indication to remove the prosthesis before radiation therapy of the chest wall.

Diabetic patients with foot burns

We describe six patients with non-insulin dependent (Type 2) diabetes mellitus (NIDDM) and thermal foot injury admitted to the Burn Centre in Rotterdam. They were all male with a mean age of 56.8 (range 47-63) years. The median patients' delay before admission was 27 (range 1-56) days. Five patients needed amputation. Healing of the wounds took a mean period of 9.5 (range 2-27) months. In two patients healing of the wounds took more than 1 year; these two patients also had recurrent foot burns. Neurological evaluation in four patients confirmed severe polyneuropathy and severe loss of heat pain, warmth, and cold sensation.

[Initial results of immediate reconstruction of the breast following mastectomy]

OBJECTIVE

Evaluation of the results of immediate reconstruction after mastectomy for breast cancer by means of a silicone implant.

DESIGN

Retrospective analysis.

SETTING

Department of Surgical Oncology of the Dr Daniël den Hoed Cancer Centre and Department of Surgery of the Zuiderziekenhuis, Rotterdam, the Netherlands.

METHOD

From September 1990 till July 1993, 37 immediate reconstructions of the breast after mastectomy were performed in 35 patients by means of a silicone implant. Indications for the treatment, consequences for further oncological treatment, additional plastic surgery, and complications of the reconstruction were evaluated.

RESULTS

The indications for mastectomy and immediate reconstruction were local recurrence after breast conservative treatment (6 operations), multifocal disease (8), extensive in situ carcinoma (8), non-radically removed tumour at lumpectomy (5), anticipated poor cosmetics after breast conservative treatment (6), prophylactic ablation of the breast (2), and patient preference (1). 5 patients received adjuvant systemic chemotherapy, which could be administered without delay, and without negative influence on the result of the breast reconstruction. Additional plastic surgical treatment consisting of reconstruction of the areolar complex and correction of the breast symmetry, was performed in 5 and 3 patients respectively. In 8 of the 37 reconstructions (22%) complications were encountered. The main complications were haematoma (2), infection (4), implant removal (3), capsular contracture (2), skin necrosis (2), and luxation of the implant (1).

CONCLUSION

Immediate reconstruction after mastectomy is a valuable treatment modality in breast cancer.

[Pasteurella multocida infections: bites by dogs or cats?]

Annually 50,000 to 100,000 animal bites are seen by physicians in the Netherlands. Infections of these bite wounds frequently occur. Pasteurella multocida is one of the main causes of these infections and many serious complications may occur. We present 3 patients with disturbances in wound healing after animal bites or scratches due to infection with P. multocida. In view of the high infection ratio after cat bites we advise giving amoxicillin/clavulanic acid (Augmentin) for 5 days as prophylaxis. According to the literature prophylaxis for dog bites is not necessary. However, fatal complications after dog bites due to infections with Capnocytophaga canimorsus (DF-2) support those who prefer to give antibiotics after these bites also.
