Comparing Open, Laparoscopic and Robotic Liver Resection for Metastatic Colorectal Cancer-A Systematic Review and Network Meta-Analysis.

Colorectal liver metastases (CRLM) can be surgically managed through open resections (OLR), laparoscopic resections (LLR), or robotic liver resections (RLR). However, there is ongoing uncertainty regarding the safety and effectiveness of minimally invasive approaches like LLR and RLR. This study aims to clarify these issues by conducting a network meta-analysis (NMA) to compare outcomes across OLR, LLR and RLR for patients with CRLM.

Short-term effects of cyclopentolate and tropicamide eye drops on macular choroidal thickness in myopic children.

Background: To investigate the short-term effects of cyclopentolate and tropicamide eyedrops on choroidal thickness (ChT) in myopic children using placebo or low-dose atropine eyedrops.

Methods: The analysis included 242 myopic individuals (7-19 years) enrolled in two randomised placebo-controlled clinical trials of low-dose atropine eyedrops. Cycloplegia was induced using either one drop of 1% cyclopentolate (n = 161), two drops of 1% cyclopentolate (n = 32) or two drops of 1% tropicamide (n = 49).

Circulating microRNAs can predict chemotherapy-induced toxicities in patients being treated for primary breast cancer.

Purpose: Prescribing NAC for breast cancer is a pragmatic treatment strategy for several reasons; however, certain patients suffer chemotherapy-induced toxicities. Unfortunately, identifying patients at risk of toxicity often proves challenging. MiRNAs are small non-coding RNA molecules which modulate genetic expression.

Evaluating the Necessity for Routine Sentinel Lymph Node Biopsy in Postmenopausal Patients Being Treated for Clinically Node Negative Breast Cancer the Era of RxPONDER.

Introduction: Traditionally, sentinel lymph node biopsy (SLNB) was performed to inform adjuvant chemotherapy prescription and prognosis in breast cancer. Following RxPONDER, the OncotypeDX Recurrence Score (RS) guides adjuvant chemotherapy prescription for all postmenopausal patients with estrogen receptor positive, human epidermal growth factor receptor-2 negative (ER+/HER2-) breast cancer with 0 to 3 positive lymph nodes (0-3 + LN).

Aims: To establish the oncological safety of omitting SLNB in postmenopausal patients with ER+/HER2- breast cancer indicated to undergo SLNB and to evaluate the primary determinants of chemotherapy prescription for these patients.

Comparison of the Nottingham Prognostic Index and OncotypeDX© recurrence score in predicting outcome in estrogen receptor positive breast cancer.

Introduction: Traditionally, Nottingham prognostic index (NPI) informed prognosis in patients with estrogen receptor positive, human epidermal growth factor receptor-2 negative, node negative (ER+/HER2-/LN-) breast cancer. At present, OncotypeDX© Recurrence Score (RS) predicts prognosis and response to adjuvant chemotherapy (AC).

Aims: To compare NPI and RS for estimating prognosis in ER + breast cancer.

Relevance of the 21-gene expression assay in male breast cancer: A systematic review and meta-analysis.

Introduction: The 21-gene assay provides prognostication for estrogen receptor positive, human epidermal growth factor receptor-2 negative (ER+/HER2-) early female breast cancer patients. This signature has not been validated in male breast cancer (MBC).

Methods: A systematic review and meta-analysis was performed in accordance to the PRISMA guidelines.

Clinicopathological response to neoadjuvant therapies and pathological complete response as a biomarker of survival in human epidermal growth factor receptor-2 enriched breast cancer - A retrospective cohort study.

Background: Human epidermal growth factor receptor-2 (HER2) is overexpressed in 20-25% of breast cancers. Complete eradication of disease following neoadjuvant therapies and chemotherapy has been referred to as pathological complete response (pCR).

Aims: To determine clinicopathological predictors of pCR to neoadjuvant therapies and to evaluate pCR as a surrogate to enhanced survival.
