Use of laser-assisted indocyanine green angiography in breast reconstruction: Systematic review and meta-analysis.

Laser-assisted indocyanine green angiography allows surgeons to determine intraoperative flap perfusion and achieve the best outcomes in breast reconstruction. This study stratified outcomes based on a meta-analysis of complications including longitudinal trials comparing the clinical assessment of skin flaps during breast reconstruction. Nine studies met inclusion criteria and reported outcomes of interest (n = 2256). The risk of flap necrosis and the necessity of reoperation was statistically significantly higher in the control group.

Surgical resection, intraoperative radiotherapy and immediate plastic reconstruction: A good option for the treatment of distal extremity soft tissue sarcomas.

AIM: To show three patients with soft tissue sarcomas of distal extremities conservatively treated after tumor-board discussion, involving margin-free surgery, exclusive intraoperative radiotherapy, and immediate reconstruction. BACKGROUND: Current guidelines show clear and robust recommendations regarding the composition of the treatment of sarcomas of extremities. However, little evidence exists regarding the application of these treatments depending on the location of the primary neoplasia. Tumors that affect the distal extremities present different challenges and make multidisciplinary discussions desirable. METHODS/RESULTS: We reported 3 patients who were approached with a conservative intention, after tumor board recomendation. The goals from the treatment performed were aesthetic and functional preservation, while enruring locoregional control. We had wound healing complications in 2 of the cases, requiring additional reconstruction measures. Patients are followed up for 24, 20 and 10 months; local control is 100%, and functional preservation is 100%. CONCLUSIONS: Despite being a small series, it was sufficient to illustrate successful multidisciplinary planning, generating a therapeutic result with improved quality of life for patients who had an initial indication for extremity amputation.

Popliteal lymph node dissection for metastases of cutaneous malignant melanoma.

Popliteal lymph node dissection is performed when grossly metastatic nodal disease is encountered in the popliteal fossa or after microscopic metastasis is found in interval sentinel nodes during clinical staging of cutaneous malignant melanoma. Initially, an S-shaped incision is made to gain access to the popliteal fossa. A careful en bloc removal of fat tissue and lymph nodes is made to preserve and avoid the injury of peroneal and tibial nerves as well as popliteal vessels, following the previous recommendations. This rare surgical procedure was successfully employed in a patient with cutaneous malignant melanoma and nodal metastases at the popliteal fossa. The technique described by Karakousis was reproduced in a step-by-step fashion to allow anatomical identification of the neurovascular structures and radical resection with no post-operative morbidity and prompt recovery. Popliteal lymph node dissection is a rarely performed operative procedure. Following a lymphoscintigraphic examination of the popliteal nodal station, surgeons can be asked to explore the popliteal fossa. Detailed familiarity of the operative procedure is necessary, however, to avoid complications.

Leiomyosarcoma of the inferior vena cava: Survival rate following radical resection.

Leiomyosarcoma (LMS) of inferior vena cava (IVC) is a rare neoplasm affecting approximately 1/100,000 people. The prognosis is poor and potential curative intent occurs through challenging operations, such as vena cava resection, occasionally multivisceral when required, and vascular reconstruction. There are few retrospective series regarding this retroperitoneal neoplasm, and the aim of the present study was to discuss the experience at the São Paulo Cancer Institute and Clinics Hospital of University of São Paulo Medical School, São Paulo, Brazil. The current study is a retrospective review of 7 patients treated in the two tertiary hospitals between 2005 and 2013. Oncological and operative aspects were discussed, primarily regarding surgical aspects highlighting en bloc resection, vascular reconstruction, and the overall survival and recurrence rates. All the patients were treated with radical intent, 4 of whom underwent multivisceral resection, with the kidney being the most resected organ. The location of the IVC tumor was described using Kulaylat's description and the median tumor size was 10 cm. Vascular reconstruction was necessary in 4 patients. The overall survival rate at 3 and 5 years was 100, and 25%, respectively. The disease-free survival rate at 3 and 5 years was 57 and 20%, respectively. In conclusion, IVC LMS is a rare and severe retroperitoneal neoplasm, with multivisceral resections remaining a surgical challenge. The treatment requires numerous experienced surgeons and the impact of microscopic free margins remains unclear. Vascular reconstruction depends on several aspects regarding primarily the topography of the tumor.

Câncer de mama na gestação: relato de casos / Pregnancy-associated breast cancer: case reports

O câncer de mama na gestação vem se tomando uma realidade na medida em que a idade da primeira gestação das mulheres aumenta. Aproximadamente 3% dos tumores de mama são diagnosticados em mulheres grávidas entre os 23 e os 47 anos de idade (media de 33 anos). Por definição, o câncer de mama associado à gestação é todo câncer de mama diagnosticado durante a mesma ou até um ano após o parto. Em geral, o câncer de mama na gestação apresenta-se de forma avançada devido principalmente ao atraso no diagnóstico e no tratamento do que devido às características histológicas dos tumores. Na literatura, ainda não há um consenso sobre a melhor estratégia terapêutica a ser usada. São apresentados aqui três casos de câncer de mama durante a gestação bem como uma análise sobre aspectos patológicos, diagnósticos e terapêuticos, com base na experiência dos autores e no que há de mais recente na literatura.

Pregnancy-associated breast cancer is becoming a reality since women delay childbearing. Approximately 3% of breast cancers are diagnosed in pregnant woman between 23 to 47years (mean age 33 years). It is defined as any breast carcinoma diagnosed during pregnancy or during the first postpartum year. The pregnancy-associated breast cancer usually presents as an advanced stage, in part because of delay on diagnostic and treatment, than histological characteristics of the breast cancer. There is no consensus about the better treatment option that should being used. We report here three cases of pregnancy-associated breast cancer and discuss some clinical, histopathological, diagnostic and therapeutic aspects, showing our experience and the more recent we found in literature.
