Application of Intraoperative Radiotherapy in Early-Stage Breast Cancer Patients in a Clinical Setting.

Intraoperative radiation therapy (IORT) has gained popularity in recent years as an alternative to external beam whole breast radiation therapy (WBRT) for early-stage breast cancer. Here, we report 43-month recurrence and survival outcomes in a multiethnic cohort treated with IORT in a clinical context. Two hundred and eleven patients with low-risk features were treated with IORT for early-stage breast cancer from 2014 to 2021.

Epidemiological, clinical, and pathological characteristics of invasive breast cancer in Bedouin and Jewish women in southern Israel: a retrospective comparative study.

Background: Invasive breast cancer (IBC) is a leading cause of cancer-related death among women in Israel, regardless of ethnicity. This study compared IBC epidemiological, clinical, and pathological characteristics in Bedouin and Jewish patients in southern Israel.

Methods: Medical records of 1514 Jewish and 191 Bedouin women with IBC treated at Soroka University Medical Center between 2014 and 2021 were analyzed retrospectively.

Stage I Breast Cancer in the Modern Era: A Retrospective Cohort Study of 328 Patients Diagnosed from 2002 to 2006 with a 14-Year Median Follow-Up.

Introduction: This study aimed to evaluate the long-term outcomes of stage I breast cancer (BC) patients diagnosed during the current era of screening mammography, immunohistochemistry receptor testing, and systemic adjuvant therapy.

Methods: A retrospective cohort study was conducted on 328 stage I BC patients treated consecutively in a single referral center with a follow-up period of at least 12 years. The primary endpoints were invasive disease-free survival (IDFS) and overall survival (OS).

Relaxation-Diffusion T2-ADC Correlations in Breast Cancer Patients: A Spatiotemporally Encoded 3T MRI Assessment.

Quantitative correlations between T2 and ADC values were explored on cancerous breast lesions using spatiotemporally encoded (SPEN) MRI. To this end, T2 maps of patients were measured at more than one b-value, and ADC maps at several echo time values were recorded. SPEN delivered quality, artifact-free, TE-weighted DW images, from which T2-ADC correlations could be obtained despite the signal losses brought about by diffusion and relaxation.

Probing lipids relaxation times in breast cancer using magnetic resonance spectroscopic fingerprinting.

Objectives: To investigate the clinical relevance of the relaxation times of lipids within breast cancer and normal fibroglandular tissue in vivo, using magnetic resonance spectroscopic fingerprinting (MRSF).

Methods: Twelve patients with biopsy-confirmed breast cancer and 14 healthy controls were prospectively scanned at 3 T using a protocol consisting of diffusion tensor imaging (DTI), MRSF, and dynamic contrast-enhanced (DCE) MRI. Single-voxel MRSF data was recorded from the tumor (patients) - identified using DTI - or normal fibroglandular tissue (controls), in under 20 s.

Neoadjuvant therapy with doxorubicin-cyclophosphamide followed by weekly paclitaxel in early breast cancer: a retrospective analysis of 200 consecutive patients treated in a single center with a median follow-up of 9.5 years.

Purpose: We analyzed outcomes of doxorubicin-cyclophosphamide (AC) followed by weekly paclitaxel as neoadjuvant chemotherapy (NAC) for breast cancer (BC), in an everyday practice with long-term follow-up of patients.

Methods: All patients (n = 200) who received the AC-paclitaxel combination as NAC for BC at the Soroka University Medical Center from 2003 to 2012 were included in this retrospective cohort study. AC was administered on an every 3-week schedule (standard dose) until May, 2007 (n = 99); and subsequently every 2-week dose dense (dd) (n = 101).

Diffusivity in breast malignancies analyzed for b > 1000 s/mm at 1 mm in-plane resolutions: Insight from Gaussian and non-Gaussian behaviors.

Diffusion-weighted imaging (DWI) can improve breast cancer characterizations, but often suffers from low image quality -particularly at informative b > 1000 s/mm values. The aim of this study was to evaluate multishot approaches characterizing Gaussian and non-Gaussian diffusivities in breast cancer. This was a prospective study, in which 15 subjects, including 13 patients with biopsy-confirmed breast cancers, were enrolled.

Cell-free DNA concentration in patients with clinical or mammographic suspicion of breast cancer.

Mammography has a crucial role in the detection of breast cancer (BC), yet it is not limitation-free. We hypothesized that the combination of mammography and cell-free DNA (cfDNA) levels may better discriminate patients with cancer. This prospective study included 259 participants suspected with BC before biopsy.

[Plasma DNA measurement as a biomarker of cancer].

Background: Carcinoembryonic antigen (CEA) and CA 15-3 serve as biomarkers in the two prevalent cancers of the colon and breast, respectively. However, their sensitivity for screening is tow. Circulating DNA has been suggested as a potential marker.

Measurement of circulating cell-free DNA levels by a simple fluorescent test in patients with breast cancer.

Objectives: To evaluate circulating cell-free DNA (CFD) measured by a simple fluorescent assay as a biomarker of breast cancer.

Methods: We enrolled 38 patients with breast cancer before surgery, two patients with noncancerous breast lesions, nine patients after surgery, 16 healthy participants, and 29 control women admitted to the hospital emergency ward and released without hospitalization. CFD levels were measured by a direct fluorescence assay.

Can intensive care physicians safely perform percutaneous dilational tracheostomy? An analysis of 207 cases.

Background: Percutaneous tracheostomy has largely replaced surgical tracheostomy in the intensive care unit setting. Although it seems logical that surgeons continue to do tracheostomies, anesthesiologists and intensive care specialists are familiar with airway control and guide wire techniques and could replace surgeons in the performance of PDT.

Objectives: To assess the safety and effectiveness of bedside PDT in the ICU.

The effect of hypertonic (3%) saline with and without furosemide on plasma osmolality, sodium concentration, and brain water content after closed head trauma in rats.

Adding furosemide (F) to mannitol causes a greater decrease of brain volume, intracranial pressure, and brain water content (BW) as compared with mannitol alone. We examined whether adding F to hypertonic saline (HS) causes less increase of BW early after closed head trauma (CHT) as compared with HS alone. With institutional approval, 125 rats underwent sham surgery or CHT and then immediately received no treatment, HS (1.
