Clinical Utility of the 12-Gene DCIS Score Assay: Impact on Radiotherapy Recommendations for Patients with Ductal Carcinoma In Situ.

Objective: The aim of this study was to determine the impact of the results of the 12-gene DCIS Score assay on (i) radiotherapy recommendations for patients with pure ductal carcinoma in situ (DCIS) following breast-conserving surgery (BCS), and (ii) patient decisional conflict and state anxiety.

Methods: Thirteen sites across the US enrolled patients (March 2014-August 2015) with pure DCIS undergoing BCS. Prospectively collected data included clinicopathologic factors, physician estimates of local recurrence risk, DCIS Score results, and pre-/post-assay radiotherapy recommendations for each patient made by a surgeon and a radiation oncologist.

Cephalic vein cut-down verses percutaneous access: a retrospective study of complications of implantable venous access devices.

Background: Central venous access devices play an integral role in providing long-term venous access. Percutaneous and cut-down techniques have been used with varying complications.

Methods: Between January 1998 and July of 2001, 358 venous access devices were placed at Albert Einstein Medical Center in Philadelphia, Pennsylvania.

Carcinoid tumor of the breast: treatment with breast conservation in three patients.

Background: Carcinoid tumors of the breast have been described in the literature. The diagnosis is made by identification of typical histologic features and confirmed by a positive argyrophilic reaction or the presence of neurosecretory granules. There are several theories of the pathogenesis of carcinoid tumors in the breast and controversy as to whether these tumors actually originate in the breast ducts or are tumors that arise from neuroectodermal cells that have migrated to the breast ducts.

The use of closed suction drainage after lumpectomy and axillary node dissection for breast cancer. A prospective randomized trial.

Closed suction drainage has been used to prevent seroma formation after lumpectomy and axillary node dissection for breast cancer. To study the efficacy of closed suction drains, the authors conducted a prospective randomized study from 1987 to 1990 of 227 axillary dissections. One hundred eight were randomized to a drain group (DG) and 119 to a no drain group (NDG).

[Immediate hypersensitivity to lacrimal gland proteins in sicca syndromes].

A biological study was conducted on tears from 20 subjects with a clinical sicca syndrome. Electrophoresis of lacrymal proteins, determination of lacrymal and salivary immunoglobulins G, and a human basophil degranulation test (HBDT) with a lacrymal gland extract as antigen were performed in each patient. Three different groups could be distinguished: a group with normal electrophoresis and normal HBDT corresponding to hyposecretion; a second group with abnormal electrophoresis and negative HBDT corresponding to an inflammatory state of the lacrymal gland; and a third group with abnormal electrophoresis and positive HBDT corresponding to a deficit in synthesis function of the lacrymal gland.
