Sentinel lymph node biopsy and aberrant lymphatic drainage in recurrent breast cancer: Findings likely to change treatment decisions.

BACKGROUND AND OBJECTIVES: It is not clear whether sentinel lymph node biopsy (SLNB) can be applied to patients with a second breast cancer or recurrence occurring at previously treated breast. The purpose of this study was to assess the feasibility of SLNB procedure in patients with recurrent breast cancer. METHODS: Patients with non-metastatic recurrent N0 breast cancer at ipsilateral breast were included. Patients were grouped according to their initial breast, axilla, and overall surgery. Presence of drainage and its pattern as well as SLNB success rate and overall axillary involvement rates were assessed. Findings were compared. RESULTS: Out of 75 patients, mean age was 52.5 years and disease-free interval was 82 (9-312) months. Lymphatic drainage was successful in 42 (56%) patients. Drainage positivity was more frequent in patients who were previously treated with SLNB (82.6%) than in patients who underwent axillary lymph node dissection (ALND) (44.2%; P = 0,002). Aberrant lymphatic drainage was detected in 64.3% of drainage positive patients. Success rate of reoperative SLNB was 92.9%. Adjuvant treatment plan was altered in 12 (16%) patients. In 15 patients, negative SLNB prevented axillary dissection. CONCLUSIONS: Reoperative SLNB seems to be technically feasible in N0 recurrent breast cancer patients. It may further avoid unnecessary ALND and lead changes in adjuvant treatment plans. J. Surg. Oncol. 2016;114:796-802. © 2016 2016 Wiley Periodicals, Inc.

Lapatinib and platinum-based chemotherapy ameliorate breast cancer with choroidal metastasis and restore visual acuity.

Involvement of the central nervous system in metastatic breast cancer is a particularly dismal occurrence because of its effects on mortality and quality of life. Development of choroidal metastasis in a breast cancer patient indicates poor prognosis and has become the major life-limiting problem. Various treatment modalities for choroidal metastasis have been applied with different efficacy. Here we describe a patient with HER2-overexpressing breast cancer and limited choroidal metastasis who responded to an HER2 tyrosine kinase inhibitor after failure of radiotherapy and chemotherapy. Her visual acuity was completely and durably restored after the targeted therapy. This case provides a unique treatment experience of breast cancer with choroidal metastasis.

Carcinoma de células fusiformes tipo “fibromatosis-like”: una variante inusual de carcinoma metaplásico de mama asociado a carcinoma ductal / No disponible

El carcinoma de células fusiformes tipo fibromatosis-like esuna variante del carcinoma metaplásico, que ha sido reconocidorecientemente como una entidad distinta e independiente del restode los tumores metaplásicos, que recuerda a la fibromatosis yse caracteriza por ser un tumor de bajo grado, con mejor pronósticoy tendencia a la recidiva local. Presentamos un caso de unapaciente de 71 años con un carcinoma tipo fibromatosis-likeasociado a un carcinoma ductal de la mama. La histología revelóun tumor de células fusiformes simulando una fibromatosis, dondese puede identificar un componente epitelial en forma de carcinomaductal o intraductal en continuidad con el componente deaspecto fusiforme. Inmunohistoquímicamente presentó positividadfocal para marcadores epiteliales y mioepiteliales como citoqueratinasy expresión de marcadores mesenquimales como vimentina.El diagnóstico exacto puede presentar dificultad tantoradiológica como anatomopatológica y plantea el diagnóstico diferencialcon lesiones benignas como fibromatosis, fascitis nodularo malignas como sarcomas. El comportamiento y pronósticono ha sido del todo aclarado aunque se ha visto que es un tumorque se caracteriza por un alto riesgo de recidiva, bajo potencialpara metastatizar en ganglios linfáticos regionales pero con capacidadpara producir metástasis a distancia y por tanto, debería sertratado en consecuencia(AU)

Fibromatosis-like spindle cell carcinoma of the breast is avariant of metaplastic carcinoma that has recently been recognizedas a different entity because of its resemblance to fibromatosisand similar propensity for local recurrence. We presenta case of 71- year-old lady with a fibromatosis-like carcinomaassociated with ductal carcinoma of the breast. Finalhistology revealed a tumor with predominant spindle cells in acollagenous background, simulating a fibromatosis. Inmunohistochemistryshowed focal positivity of ephithelial and myoephitelialmarkers as citokeratins and expression of mesenchymalmarker as vimentin in the tumor. This tumor can posediagnostic difficulty radiologic as histopathology and the differentialdiagnosis includes both benign and malignant spindlecell breast lesions as a fibromatosis, nodule fascitis or sarcomas.The behaviour and prognosis have not been well clarifiedalthough there seems to have high risk of local recurrence, lowpotential to metastasize to regional lymph nodes and potentialfor distant metastasis and should be treated accordingly(AU)

Clinical study on treatment of mammary cancer by shenqi fuzheng injection in cooperation with chemotherapy.

OBJECTIVE: To study the effect of Shenqi Fuzheng Injection (SFI) on cellular immune in patients with mammary cancer (MC) after chemotherapy. METHODS: One hundred and ten patients with MC were randomly assigned to two groups. The 58 patients in the tested group were treated with SFI in cooperation with chemotherapy of CAF protocol (Cyclophosphamide, Doxorubicin and Fluorouracil), while the 52 patients in the control group were treated with chemotherapy of the same protocol alone. Changes of the patients' quality of life (QOF), adverse reaction that occurred, peripheral lymphocyte count and killing activity of single karyocyte before and after treatment between the two groups were compared. RESULTS: Patients' QOF elevating rate after treatment in the tested group and the control group was 34.5% and 13.5% respectively; The lowering of peripheral blood cell count of WBC, platelet and lymphocyte as well as that of the killing activity of single peripheral karyocyte on various kinds of MC cells were all milder and recovery sooner than those in the control group. CONCLUSION: SFI in combination with chemotherapy in treating MC could reduce the occurrence of adverse reaction to chemotherapy, improve clinical symptoms, elevate QOF and enhance immunity in patients with MC.
