ER-Targeted PET for Initial Staging and Suspected Recurrence in ER-Positive Breast Cancer.

Importance: There are insufficient data comparing 16α-18F-fluoro-17β-estradiol (FES) positron emission tomography (PET) computed tomography (CT) with standard-of-care imaging (SOC) for staging locally advanced breast cancer (LABC) or evaluating suspected recurrence.

Objective: To determine the detection rate of FES PET/CT and SOC for distant metastases in patients with estrogen receptor (ER)-positive LABC and recurrences in patients with ER-positive BC and suspected recurrence.

Design, Setting, And Participants: This diagnostic study was conducted as a single-center phase 2 trial, from January 2021 to September 2023.

Recurrence and Survival Rates for 1400 Early Breast Tumors Treated with Intraoperative Radiation Therapy (IORT).

Introduction: Intraoperative radiotherapy (IORT) permits accurate delivery of radiation therapy directly to the tumor bed. We report local, regional, and distant recurrence data along with overall and breast cancer-specific survival for 1400 tumors treated with x-ray IORT.

Methods: A total of 1367 patients with 1400 distinct tumors were enrolled in a registry trial.

Autologous mastectomy reconstruction: Communication among the breast surgery team to maximize aesthetic and oncologic outcome.

Mastectomy breast reconstruction with autologous tissue is challenging. Oncologic and aesthetic goals face previous surgical scars, radiation, chemotherapy, or other comorbidities. We describe a simple approach for autologous mastectomy reconstruction so that breast and plastic and reconstructive surgeons can maximize aesthetic outcomes and minimize wound complications.

Intraoperative Radiation Therapy (IORT): A Series of 1000 Tumors.

Background: Two prospective, randomized trials, TARGIT-A and ELIOT, have shown intraoperative radiation therapy to be a safe alternative, with a low-risk of local recurrence, compared with whole breast radiation therapy, following breast-conserving surgery, for selected low-risk patients. We report the first 1000 tumors treated with this modality at our facility.

Methods: A total of 1000 distinct breast cancers in 984 patients (16 bilateral) were treated with breast conserving surgery and X-ray IORT from June 2010 to August 2017.

Intraoperative Radiation Using Low-Kilovoltage X-Rays for Early Breast Cancer: A Single Site Trial.

Introduction: Two prospective, randomized trials, TARGIT-A and ELIOT, have shown intraoperative radiation therapy (IORT) to be a safe alternative to whole breast radiation therapy following breast-conserving surgery for selected low-risk patients. However, minimal data are available about the clinical effectiveness of this modality of treatment using the Xoft Axxent Electronic Brachytherapy (eBx) System.

Methods: A total of 201 patients with 204 early-stage breast cancers were enrolled in a prospective X-ray IORT trial from June 2010 to September 2013.

Acute and Chronic Complications in Patients with Ductal Carcinoma in Situ Treated with Intraoperative Radiation Therapy.

Intraoperative radiation therapy (IORT) delivers radiation therapy directly to the tumor bed at the time of surgery. Minimal data are available regarding IORT complications in patients diagnosed with ductal carcinoma in situ (DCIS) using the Xoft Axxent eBx System. 146 patients with pure DCIS received X-ray based IORT therapy using the Xoft Axxent eBx System at Hoag Memorial Hospital Presbyterian between June 2010 to April 2016 and were accrued to an IORT data registry study.

Acute and Chronic Complications in Breast Cancer Patients Treated with Intraoperative Radiation Therapy.

Introduction: Intraoperative radiation therapy (IORT) permits the delivery of radiation therapy directly to the tumor bed at the time of surgery. Minimal data are available about the complications associated with this modality of treatment using the Xoft(®) Axxent Electronic Brachytherapy (Axxent) System.

Methods: A total of 702 patients who received IORT using the Xoft(®) Axxent System at Hoag Memorial Hospital Presbyterian between June 2010-February 2016 were accrued in an IORT data registry study.

Durable complete response of refractory, progressing metastatic melanoma after treatment with a patient-specific vaccine.

A patient with metastatic melanoma who experienced a durable complete response after treatment with a patient-specific vaccine has been described in this article. This 59-year-old woman presented with cervical spine metastases and, within the year, had experienced local disease progression and, despite various therapies, metastases to the axilla, rectum, gall bladder, and multiple soft-tissue sites. She had previously received radiation therapy, combination chemotherapy, interleukin-2 plus interferon biotherapy, and gamma knife radiosurgery, and undergone multiple surgical resections.

Nitrofen inhibition of pulmonary growth and development occurs in the early embryonic mouse.

Background/purpose: It was believed previously that pulmonary hypoplasia in congenital diaphragmatic hernia (CDH) was a consequence of the herniation of abdominal viscera into the chest. Using the murine nitrofen-induced model of CDH, the authors evaluated lung growth and development before diaphragm closure or herniation.

Methods: The authors examined nitrofen-exposed early embryonic lungs on embryonic day 12 (E12).
