Using Deauville Scoring to Guide Consolidative Radiotherapy in Diffuse Large B-Cell Lymphoma.

Background: The most common aggressive lymphoma in adults is diffuse large B-cell lymphoma (DLBCL). Consolidative radiotherapy (RT) is often administered to DLBCL patients but guidelines remain unclear, which could lead to unnecessary RT. We aimed to evaluate the value of end-of-treatment PET-CT scans, interpreted using the Deauville score (DV), to guide the utilization of consolidative RT, which may help spare low-risk DLBCL patients from unnecessary RT.

Oncologic outcomes after MRI-assisted image-guided brachytherapy with hybrid interstitial and intra-cavitary applicators under moderate sedation for locally advanced cervix cancer.

Purpose: To report outcomes of using image-guided hybrid intra-cavitary/interstitial applicators under moderate sedation for locally advanced cervical cancer patients in our institution.

Material And Methods: A total of 69 fractions of brachytherapy with hybrid applicators were performed in 33 patients from January 2017 to April 2021. All patients underwent MRI pelvis 1 week pre-brachytherapy to determine suitability for interstitial brachytherapy and pre-plan needle placement.

Minimizing transmission of COVID-19 while delivering optimal cancer care in a National Cancer Centre.

The COVID-19 pandemic has disrupted current models of healthcare and adaptations will likely continue. With the gradual easing of lockdown measures worldwide, cancer centres must be prepared to implement novel means to prevent repeated waves of infection. There are two limitations unique to oncology - a higher susceptibility of patients to COVID-19 and the multidisciplinary approach required of cancer management.

Stereotactic body radiotherapy for early stage lung cancer-historical developments and future strategies.

The application of radiosurgery dose escalation extra-cranially in a moving target, surrounded by critical normal tissue, presents unique dosimetric and clinical challenges. Building on a strong foundation of robust technological advancements and well-planned clinical studies, lung stereotactic body radiotherapy (SBRT) has firmly established its place in the management of early stage non-small cell lung cancer (NSCLC). Nevertheless, favourable outcomes and long-term survival still evade a substantial proportion of patients, especially for central and larger peripheral lung tumours.

In the secretory endometria of women, luminal epithelia exhibit gene and protein expressions that differ from those of glandular epithelia.

Objective: To characterize the transcriptome of luminal epithelia (LE) of fertile secretory endometria and compare the results with those from glandular epithelia (GE).

Design: Endometrial samples were collected at 2 and 7 days after initial blood LH surge in separate menstrual cycles. LE were obtained with the use of laser microdissection.

Gene and protein expression signature of endometrial glandular and stromal compartments during the window of implantation.

Objective: To map the changes in messenger RNA (mRNA) and protein abundance during the window of implantation in specifically endometrial stromal and glandular epithelial cells obtained using laser microdissection microscopy (LDM).

Design: Endometrial samples were collected from two menstrual cycles at 2 and 7 days after first significant rise in blood LH, and separate cell populations were obtained using LDM. A new generation linear polymerase chain reaction (PCR) amplified the mRNA, which were hybridized to both Affymetrix U133 Plus2 and Agilent 4x44K microarrays followed by gene set analysis.

Vascular endothelial growth factor and leptin: regulation in human cumulus cells and in follicles.

Background: The factors that determine oocyte competency are poorly understood. It is believed that angiogenic factors are crucial. Modulation of these factors is therefore a central consideration.

Absence of association of androgen receptor trinucleotide expansion and poor semen quality.

This study investigated the relationship between variation in the polymorphic CAG trinucleotide repeat (TNR) region of the human androgen receptor (AR) gene and semen quality in a Caucasian sample population. These men were patients attending the New Zealand Centre for Reproductive Medicine in Christchurch. The AR TNR region was amplified by polymerase chain reaction and then DNA sequenced to determine exact numbers of CAG repeats for each sample.
