RESUMO

BACKGROUND: Autologous fat transplantation (AFT) to the breast can correct defects and be a part of a breast reconstruction to achieve a better aesthetic result. The impact of AFT on the radiological evaluation and detection of cancer remains unclarified. The aim of this study is to investigate whether AFT induces lasting modifications. METHODS: In the present study, a valuation was performed of 44 breasts from 37 patients examined with mammography and ultrasound before and after autologous fat transplantation. Breast radiologists evaluated the images using a study specific protocol. RESULTS: AFT did not hinder post-operative assessment of mammograms or ultrasound. No detectable changes with serious clinical impact were found after injections of mean 177 ml (34-516) of fat in one to four sessions. The rate of oil cysts was significantly higher after AFT than pre-operatively (2.3 vs. 34.1 % p = 0.0013). Significantly more post-operative oil cysts were detected after injection of larger volumes of fat (144 vs. 243 ml, p = 0.013). No significant differences were found in the post-operative images regarding age at surgery, follow-up time, or time from previous breast surgery. CONCLUSION: AFT does not impair assessment of mammograms and ultrasound in patients who have a history of breast cancer surgery or prophylactic mastectomy.

RESUMO

BACKGROUND: Patients with cutaneous melanoma (CM) on the trunk have a worse prognosis than those with extremity CM. One reason could be multiple or uncommon (outside axilla or groin) sentinel node locations (SNLs). METHODS: We identified 859 patients who underwent sentinel node biopsy for trunk (n = 465) or extremity (n = 394) CM in three Swedish healthcare regions from 2000 to 2008. We collected patient, tumor, and sentinel node characteristics through clinical registers and medical records. We investigated the distribution of SNLs in a logistic regression model, and risk of overall and melanoma-specific death through 2011 in a multivariable Cox regression model. RESULTS: Trunk CM was associated with multiple SNLs (31 vs. 7 %; odds ratio [OR] 7.1; 95 % confidence interval [CI] 4.6-11.5; p < 0.001) but not uncommon SNLs (8 vs. 7 %; OR 1.1; 95 % CI 0.6-1.9; p = 0.75) compared with extremity CM. The increased risk of melanoma-specific death was confirmed for trunk CM (hazard ratio [HR] 1.9; 95 % CI 1.3-2.9; p = 0.003), especially on the upper back (HR 2.3; 95 % CI 1.4-3.6; p < 0.001) compared with extremity CM. Uncommon SNLs (HR 0.5; 95 % CI 0.2-1.4; p = 0.21) or multiple SNLs (HR 1.1; 95 % CI 0.4-2.9; p = 0.81) were not associated with melanoma-specific death compared with those with common/single SNL. CONCLUSIONS: Trunk melanomas were associated with multiple lymph drainage, but the worse prognosis of trunk melanomas could not be explained by the increased frequency of multiple or uncommon SNLs.

RESUMO

Background: Acellular dermal matrices (ADMs) are sometimes used in implant-based breast reconstructions (IBR), but long-term ADM-related evaluations are scarce. In this study, we evaluated early and late complications and patient-related outcomes (PROs) over an 8-year postoperative period in women who had undergone immediate IBR following risk-reducing mastectomy with bovine ADM (SurgiMend). Methods: This prospective observational single-center analysis involved 34 women at high risk for breast carcinoma. Complications were prospectively recorded during the first year, followed by 4 years of postoperative retrospective chart reviews. Long-term evaluations were done using a questionnaire. Preoperative, 1 year, and 5- to 8-year postoperative PRO assessments were obtained based on results from the BREAST-Q questionnaire. Results: In 56 breasts, complications after a mean of 12.4 months follow-up included implant loss (7.1%), implant change (1.8%), hematoma (7.1%), breast redness (41.1%), and seroma (8.9%). Most breasts (80.3%) were graded Baker I/II, which indicated a low capsular contracture incidence. After a mean of 6.9 years, the total implant explantation rate was 33.9%, and the revision surgery rate was 21.4%. Two cases of breast cancer were reported during the long-term evaluation. BREAST-Q results indicated significantly decreased satisfaction with outcome (P = 0.024). A positive trend regarding psychosocial well-being and declining trend regarding satisfaction with both breast physical- and sexual well-being parameters were reported. Conclusions: The observed complication rates agree with previous findings concerning ADM-assisted IBR. A high demand for revision surgery exists, and PROs remain relatively stable over time.

RESUMO

Radiotherapy is important in breast cancer treatment. A side effect of the treatment is fibrosis that decreases the possibility for a successful breast reconstruction with expanders and with high patient satisfaction with the result. The most common option for mastectomized, irradiated women wishing for a breast reconstruction is autologous tissue transplantation. However, some patients are not suitable for flap surgery. Fifty mastectomized and irradiated women were included in a randomized controlled trial. They underwent breast reconstruction with expanders and were allocated 1:1 to either receive pre-treatment with autologous fat transplantation (AFT) or not. Primary outcomes were frequency of reoperations and complications. Secondary outcomes were number of days in hospital, number of outpatient visits to surgeon or nurse and patient reported outcome as reported with Breast Q. Follow-up time was 2 years. Fifty-two per cent of the intervention group and 68% of the controls underwent reoperations (p = 0.611). Thirty-two per cent of the intervention group and 52% of the controls had complications (p = 0.347). The median number of consultations with the nurse was four in the intervention group and six in the control group (p = 0.002). The AFT patients were significantly more satisfied with their breasts and psychosocial well-being after 2 years. They also had higher increase in satisfaction with breasts, psychosocial well-being, and sexual well-being when comparing baseline with 2 years postoperatively. This randomized controlled trial indicates benefits of AFT prior to breast reconstruction with expanders, especially on patient reported outcome even if the study sample is small.

RESUMO

BACKGROUND: The European Society of Plastic, Reconstructive and Aesthetic Surgery (ESPRAS) comprises 40 national societies across Europe. In addition to ESPRAS, there are 8 different European Plastic Surgery societies representing Plastic Surgeons in Europe. The 4th European Leadership Forum (ELF) of ESPRAS, held under the motto "Stronger together in Europe" in Munich in 2023, aimed to collect and disseminate information regarding the national member societies of ESPRAS and European societies for Plastic Surgeons. The purpose was to identify synergies and redundancies and promote improved cooperation and exchange to enhance coordinated decision-making at the European level. MATERIAL AND METHODS: An online survey was conducted regarding the organisational structures, objectives and challenges of national and European societies for Plastic Surgeons in Europe. This survey was distributed to official representatives (Presidents, Vice Presidents and General Secretaries) and delegates of national and European societies at the ELF meeting. Missing information was completed using data obtained from the official websites of the respective European societies. Preliminary results were discussed during the 4th ELF meeting in Munich in March 2023. RESULTS: The ESPRAS survey included 22 national and 9 European Plastic Surgery societies representing more than 7000 Plastic Surgeons in Europe. Most national societies consist of less than 500 full members (median 182 members (interquartile range (IQR) 54-400); n=22). European societies, which covered the full spectrum or subspecialities, differed in membership types and congress cycles, with some requiring applications by individuals and others including national societies. The main purposes of the societies include research, representation against other disciplines, specialisation and education as well as more individual goals like patient care and policy regulation. CONCLUSION: This ESPRAS survey offers key insights into the structures, requirements and challenges of national and European societies for Plastic Surgeons, highlighting the relevance of ongoing close exchange between the societies to foster professional advancement and reduce redundancies. Future efforts of the ELF will continue to further explore strategies for enhancing collaboration and harmonisation within the European Plastic Surgery landscape.

RESUMO

Mohs micrographic surgery is the preferred surgical option for high-risk basal cell carcinomas. In our institution, the method is exclusively used for the treatment of aggressive and recurrent facial tumours selected via multidisciplinary team meetings and consistently managed using a multidisciplinary approach. The aim of this retrospective patient-record study was to examine the outcomes for basal cell carcinomas managed with Mohs micrographic surgery and to present our experience from multidisciplinary team meetings and interdisciplinary collaborations. All patients treated between September 2009 and March 2019 at Karolinska University hospital were included. In a total of 143 facial basal cell carcinomas in 138 patients, 86 primary and 57 recurrent, the recurrence rate was 4.9% after a median follow-up of 24 months. In regions, where highly specialised Mohs surgeons performing all the steps of the procedure are limited, interdisciplinary collaboration can be an effective strategy for appropriate patient selection and for performing all steps of Mohs surgery with dermatosurgeons eradicating the tumour, pathologists evaluating the histopathology, followed by reconstructive surgery by plastic surgeons. The approach we present here provides a robust and functioning Mohs surgical service during the build-up of the organisation, while providing the opportunity to train new surgeons. Once the clinic has been set up, the multidisciplinary approach should always be considered and applied when dealing with complex cases.

RESUMO

BACKGROUND: Cure proportion represents the proportion of patients who experience the same mortality rate as the general population and can be estimated together with the survival of the proportion experiencing excess mortality (the uncured). The aim was to estimate the cure proportions and survival among uncured stage II-III cutaneous melanoma (CM) patients. METHODS: 1- and 5-year relative survival ratios, cure proportions and the median survival times of uncured stage II-III CM patients in Sweden (n = 6466) were calculated based on data from the nationwide population-based Swedish Melanoma Register 2005-2013 with a follow-up through 2018. RESULTS: Stages IIB and IIC showed significant differences in standardized cure proportions vs. stage IIA CM (0.80 (95% CI 0.77-0.83) stage IIA; 0.62 (95% CI 0.59-0.66) stage IIB; 0.42 (95% CI 0.37-0.46) for stage IIC). Significant differences in standardized cure proportions were found for stages IIIB and IIIC-D CM vs. stage IIIA (0.76 (95% CI 0.68-0.84) stage IIIA; 0.52 (95% CI 0.45-0.59) stage IIIB; 0.35 (95% CI 0.30-0.39) for stage IIIC-D). CONCLUSIONS: The results are emphasizing the poor prognosis with low proportions cured by surgery only for sub-groups of stage II-III CM, specifically within stages IIB-C CM.

RESUMO

AIM: To investigate the occurrence of complications after a needle puncture or intravenous injection in the ipsilateral arm of women who have undergone axillary lymph node clearance for breast cancer. BACKGROUND: After axillary lymph node clearance in patients with breast cancer, some women experience lymphoedema and recurrent infections. To reduce the risk of these postoperative complications, most women are advised to not have intravenous infusions in, or blood samples taken from, the arm in the operated side. Very little published data are available regarding the incidence of lymphoedema after intravenous procedures under clean conditions in the hospital setting. This study set out to investigate the occurrence of complications after a needle puncture or intravenous injection in the ipsilateral arm of women who have undergone axillary lymph node clearance for breast cancer is therefore important. DESIGN: Descriptive. METHODS: Self-reported questionnaire. RESULTS: Most of the reported complications were minor, including itching, bruises and vomiting at the time of the intravenous procedure. The most serious complication was infection in one patient needing antibiotic treatment and subsequent arm swelling. CONCLUSIONS: This study indicates that if a blood sample is taken or intravenous injection is given according to the current Swedish guidelines for health care professionals, there should be a very low risk of complications. RELEVANCE TO CLINICAL PRACTICE: If intravenous procedures are performed without any disadvantage in the arm of the operated side in women who have undergone axillary surgery, the clinical problem of finding a proper vein and the psychological concern of the women can be reduced.

RESUMO

BACKGROUND: Completion lymph node dissection (CLND) for malignant melanoma is performed for regional cancer control and is associated with a high complication rate. It is unknown whether post-operative complications influence cancer recurrence or survival. Our aim was to evaluate the risk factors for short- and long-term complications after CLND, and to determine whether complications affect recurrence or survival. METHOD: We performed a retrospective cohort study including all melanoma patients who underwent CLND in the Stockholm region during 2005-2014. Patient and cancer characteristics were collected from medical records, as were clinical outcomes. Assessment was performed by multivariate logistic regression. RESULTS: Among 144 patients, the risk of any post-operative one year complication was 68.8%. Lymphedema (41.0%), infection (37.5 %), and seroma (31.3 %) were the most common complications. Diabetes and inguinal CLND were associated with nine- and ten-fold increased risks of post-operative complications (p<0.05), respectively. Complications were linked to an increased risk of recurrent cancer (p<0.05), median follow-up time of 49 months, but did not appear to affect five-year survival. CONCLUSION: Post-operative complications are common in melanoma patients undergoing CLND. Strong risk factors for complications are diabetes and inguinal CLND. Post-operative complications appear to be associated with increased risks of recurrent cancer, but the mechanism is unknown.

RESUMO

BACKGROUND: Autologous fat transplantation (AFT) is being increasingly used to improve the results after breast-conserving surgery and breast reconstruction. However, studies on patient-reported outcomes (PROs) and health-related quality of life (HRQoL) after AFT are scarce. The aim of this prospective longitudinal case-series study was to assess PRO in women who had undergone AFT after surgery for breast cancer or risk-reducing mastectomy. METHODS: Fifty women, who had undergone breast-conserving surgery or breast reconstruction, needing corrective surgery, were consecutively included between 2008 and 2013. A 20-item study-specific questionnaire (SSQ) and the Short Form Health Survey (SF-36) were used pre-operatively and 6 months, 1 year and 2 years post-operatively, to evaluate PRO and HRQoL. RESULTS: The patients underwent three (1-4) AFT procedures, with the injection of 164 ml (median) (range 40-516) fat. Thirty-eight and 34 patients completed the study-specific questionnaire and the SF-36, respectively, both pre-operatively and after 2 years. Sixteen of the 20 items in the SSQ were improved after 2 years, including breast size (p < 0.0001), shape (p < 0.0001), appearance (p < 0.0001), softness of the breast (p = 0.001), pain in the region (p = 0.005), scarring from previous breast surgery (p < 0.001) and willingness to participate in public physical activities (p < 0.001). HRQoL did not largely differ before and after AFT, or between the study group and a reference population. CONCLUSIONS: AFT alone or in combination with other corrective surgical procedures, improved PRO after breast-conserving surgery and breast reconstruction in both irradiated and non-irradiated women.

RESUMO

BACKGROUND: Techniques based on radio frequency (RF) energy have many applications in medicine, in particular tumour ablation. Today, mammography screening detects many breast cancers at an early stage, facilitating treatment by minimally invasive techniques such as radio frequency ablation (RFA). The breast cancer is mostly surrounded by fat, which during RFA-treatment could result in preferential heating of the tumour due to the substantial differences in electrical parameters. The object of this study was to investigate if this preferential heating existed during experimental in vitro protocols and during computer simulations. METHODS: Excised breast material from four patients with morphologically diagnosed breast cancers were treated with our newly developed RFA equipment. Subsequently, two finite element method (FEM) models were developed; one with only fat and one with fat and an incorporated breast cancer of varying size. The FEM models were solved using temperature dependent electrical conductivity versus constant conductivity, and transient versus steady-state analyses. RESULTS: Our experimental study performed on excised breast tissue showed a preferential heating of the tumour, even if associated with long tumour strands. The fat between these tumour strands was surprisingly unaffected. Furthermore, the computer simulations demonstrated that the difference in electrical and thermal parameters between fat and tumour tissue can cause preferential heating of the tumour. The specific absorption rate (SAR) distribution changed significantly when a tumour was present in fatty tissue. The degree of preferential heating depended on tissue properties, tumour shape, and placement relative to the electrode. Temperature dependent electrical conductivity increased the thermal lesion volume, but did not change the preferential heating. Transient solutions decreased the thermal lesion volume but increased the preferential heating of the tumour. CONCLUSION: Both the computer model and the in vitro study confirmed that preferential heating of the tumour during RFA exists in breast tissue. However, the observed preferential heating in the in vitro studies were more pronounced, indicating that additional effects other than the difference in tissue parameters might be involved. The existing septa layers between the cancer tissue and the fatty tissue could have an additional electrical or thermal insulating effect, explaining the discrepancy between the in vitro study and the computer model.

RESUMO

Tumors can suppress the host immune system by employing a variety of cellular immune modulators, such as regulatory T cells, tumor-associated macrophages, and myeloid-derived suppressor cells (MDSC). In the peripheral blood of patients with advanced stage melanoma, there is an accumulation of CD14(+)HLA-DR(lo/-) MDSC that suppress autologous T cells ex vivo in a STAT-3-dependent manner. However, a precise mechanistic basis underlying this effect is unclear, particularly with regard to whether the MDSC induction mechanism relies on cell-cell contact of melanoma cells with CD14(+) cells. Here, we show that early-passage human melanoma cells induce phenotypic changes in CD14(+) monocytes, leading them to resemble MDSCs characterized in patients with advanced stage melanoma. These MDSC-like cells potently suppress autologous T-cell proliferation and IFN-γ production. Notably, induction of myeloid-suppressive functions requires contact or close proximity between monocytes and tumor cells. Further, this induction is largely dependent on production of cyclooxygenase-2 (COX-2) because its inhibition in these MDSC-like cells limits their ability to suppress T-cell function. We confirmed our findings with CD14(+) cells isolated from patients with advanced stage melanoma, which inhibited autologous T cells in a manner relying up prostaglandin E2 (PGE2), STAT-3, and superoxide. Indeed, PGE2 was sufficient to confer to monocytes the ability to suppress proliferation and IFN-γ production by autologous T cells ex vivo. In summary, our results reveal how immune suppression by MDSC can be initiated in the tumor microenvironment of human melanoma.

RESUMO

Autologous transplantation of fat, or lipofilling, of the breast can correct deformities after reconstruction and after conservation surgery for cancer. We have made a retrospective evaluation of morbidity and patients' experiences of the method. Forty-four patients have had lipofilling once, twice, or three times (mean transplanted volume 40 ml, range 6-200 ml). One minor complication, a local infection, was treated with antibiotics given orally, and recorded at follow up. A questionnaire was sent to all 44 patients and answered by 43. Twenty-nine of the 43 patients reported improvement of irregularities after lipofilling, 26 reported that the shape of the breast had improved, 26 that the consistency had improved, and 20 that the size had increased postoperatively. Five of the patients reported some adverse effects; one case of liponecrosis that did not need any treatment was found one year postoperatively. No problems were reported at the donor site at follow-up.

RESUMO

The purpose of this study was to determine the safety and efficacy of percutaneous ultrasound (US) guided preferential radiofrequency ablation (PRFA) of unifocal human invasive breast carcinoma with largest radiological diameters of up to 16 mm. Thirty-three patients were enrolled in a study to be treated prior to scheduled partial mastectomy. A needle-shaped treatment electrode, successively developed in two different sizes, was placed into the center of the lesions using ultrasound guidance. A temperature of 85 degrees C was maintained for 10 min. The analysis of the resected specimen was performed using conventional histopathological methods with the aim to determine the size of the lesion as well as the potential viability of tumor cells. Of the 33 patients enrolled 31 were treated. In 26 (84%) patients a complete ablation of the tumor was achieved. Ultrasound guided preferential radiofrequency ablation of small breast carcinoma is feasible and patient friendly. The success rate depends on accurate preoperative diagnostic imaging as well as an exact position of the needle electrode.
