Impact of Granulocyte Colony-Stimulating Factor (G-CSF) on Clinical Outcomes in Allogeneic Hematopoietic Cell Transplantation: Does Speeding Up Neutrophil Engraftment Make a Difference?

Background: Despite decades of post-allogeneic hematopoietic cell transplantation (HCT) growth factor utilization, its role remains undefined, leading to ongoing debates and research. The theoretical impacts of growth factors have been challenged in numerous studies.

Methods: In this retrospective cohort study conducted at the Princess Margaret Cancer Centre, we analyzed the clinical outcomes of 509 patients who underwent allogeneic HCT between May 1, 2019, and May 31, 2022.

Oncological Outcomes From Cytoreductive Surgery and Heated Intraperitoneal Chemotherapy for Colorectal Cancer Peritoneal Metastases.

Cytoreductive surgery (CRS) is effective for colorectal cancer peritoneal metastases (CRPM) at increasing overall survival (OS) compared to systemic anticancer treatment (SACT) alone. The addition of Oxaliplatin heated intraperitoneal chemotherapy (HIPEC) has been shown in a randomized controlled trial to result in increased complications without significant OS benefit. This study evaluates outcomes for CRPM patients undergoing CRS+HIPEC with Oxaliplatin (Ox) 368mg/m (30 min), versus Mitomycin C (MMC) 35mg/m (90min).

Durvalumab with or without bevacizumab with transarterial chemoembolisation in hepatocellular carcinoma (EMERALD-1): a multiregional, randomised, double-blind, placebo-controlled, phase 3 study.

Background: Transarterial chemoembolisation (TACE) is standard of care for patients with unresectable hepatocellular carcinoma that is amenable to embolisation; however, median progression-free survival is still approximately 7 months. We aimed to assess whether adding durvalumab, with or without bevacizumab, might improve progression-free survival.

Methods: In this multiregional, randomised, double-blind, placebo-controlled, phase 3 study (EMERALD-1), adults aged 18 years or older with unresectable hepatocellular carcinoma amenable to embolisation, an Eastern Cooperative Oncology Group performance status of 0 or 1 at enrolment, and at least one measurable intrahepatic lesion per modified Response Evaluation Criteria in Solid Tumours (RECIST) were enrolled at 157 medical sites including research centres and general and specialist hospitals in 18 countries.

Nutritional Status in a Group of Patients with Wounds Due to Diabetic Foot Disease and Chronic Venous Insufficiency.

Wound healing is a complex physiological process that begins immediately upon injury. Nutritional status significantly affects the course of regenerative processes. Malnutrition can prolong the inflammatory phase, limit collagen synthesis, and increase the risk of new wound formation.

Life after Pelvic Exenteration for Rectal Cancer: The Patient and Carer Perspective on Long Term Consequences and Survivorship.

Objective: To explore the perspectives and experiences of patients and carers living with the long-term consequences of pelvic exenteration.

Summary Background Data: Pelvic exenteration is accepted as the standard of care for selected patients with locally advanced or recurrent rectal cancer. With contemporary 5-year survival reported at 40-60%, the number of long-term survivors is expected to increase.

The Role of Electroencephalography Following CAR-T Cell Therapy in Clinical Practice.

Neurotoxicity, encephalopathy, and seizures can occur following chimeric antigen receptor (CAR)-T cell therapy. Our aim was to assess what value electroencephalography (EEG) offers for people undergoing CAR-T treatment in clinical practice, including possible diagnostic, management, and prognostic roles. All patients developing CAR-T related neurotoxicity referred for EEG were eligible for inclusion.

Synergistic Effects of the Combination of Alpelisib (PI3K Inhibitor) and Ribociclib (CDK4/6 Inhibitor) in Preclinical Colorectal Cancer Models.

The CDK4/6 inhibitor Ribociclib has shown limited efficacy as a monotherapy in colorectal cancer (CRC). However, combining Ribociclib with targeted therapies could present a viable strategy for treating CRC. This study evaluated the combination of Ribociclib and the PI3K inhibitor Alpelisib across four distinct cell lines representing different mutational statuses ( wild-type, -mutated, -mutated, and -mutated).

Twenty-five patients who had proven endometrial or cervical carcinoma and had undergone radical hysterectomy have been treated with vaginal cuff electronic brachytherapy. Treatment session durations and doses to the targets and the organs at risk have been extracted from the treatment planning software.

Perspectives on the Mature T-Cell Lymphomas in the Middle East: A Comprehensive Review of the Present Status.

T-cell lymphomas (TCLs) are rare and aggressive malignancies associated with poor outcomes, often because of the development of acquired drug resistance as well as intolerance to the established and often toxic chemotherapy regimens in elderly and frail patients. The many subtypes of TCL are well established to exhibit marked geographic variation. The epidemiology, clinical presentation, diagnosis, prognosis, and treatment of TCLs in the Middle East (ME) are yet to be explored; hence, limited data are available about these entities in this part of the world.

Pulmonary Consequences of Surgical Treatment in Children's Primary Lung Tumors: A National Retrospective Study.

Background And Aims: Primary lung tumors (PLTs) in children are rare, and surgery remains the key to ensure remission. Here we describe the PLTs clinical characteristics, their management, and the pulmonary outcome following surgery.

Methods: We carried out a French national cohort of pediatric PLTs from 2013 to 2023 from the FRACTURE rare pediatric tumors national database.

Association of radiation-induced normal tissue toxicity with a high genetic risk for rheumatoid arthritis.

Purpose: Overlapping genes are involved with rheumatoid arthritis (RA) and DNA repair pathways. Therefore, we hypothesised that patients with a high polygenic risk score (PRS) for RA will have an increased risk of radiotherapy (RT) toxicity given the involvement of DNA repair.

Methods: Primary analysis was performed on 1494 prostate cancer, 483 lung cancer and 1820 breast cancer patients assessed for development of RT toxicity in the REQUITE study.

Real-world clinical outcome of unresectable locally advanced & de-novo metastatic pancreatic ductal adenocarcinoma: a multicentre retrospective study.

Background: Pancreatic ductal adenocarcinoma (PDAC) remains one of the most lethal malignancies, with limited treatment options yielding poor outcomes. This study aimed to evaluate the real-world clinical characteristics, treatment patterns, and outcomes of patients with locally advanced unresectable and de-novo metastatic PDAC in Saudi Arabia, providing regional data to compare with international benchmarks.

Methods: This is a retrospective, multicentre study involving 350 patients diagnosed with unresectable locally advanced or de-novo metastatic PDAC between January 2015 and November 2023.

International multicenter validation of AI-driven ultrasound detection of ovarian cancer.

Ovarian lesions are common and often incidentally detected. A critical shortage of expert ultrasound examiners has raised concerns of unnecessary interventions and delayed cancer diagnoses. Deep learning has shown promising results in the detection of ovarian cancer in ultrasound images; however, external validation is lacking.

Let It Grow: The Role of Growth Factors in Managing Chemotherapy-Induced Cytopenia.

Chemotherapy-induced cytopenia (CIC) is characterized by neutropenia, anemia, and thrombocytopenia, which are common and serious complications in cancer treatment. These conditions affect approximately 60% of patients undergoing chemotherapy and can significantly impact quality of life, treatment continuity, and overall survival. The use of growth factors, including granulocyte colony-stimulating factors (GCSFs), erythropoietin-stimulating agents (ESAs), and thrombopoietin receptor agonists (TPO-RAs), has emerged as a promising strategy for managing CIC.

Prognostic role of bone erosion in orbital RMS: a report from the European Pediatric Soft Tissue Sarcoma Study Group (EpSSG).

Background: Orbital rhabdomyosarcoma (RMS) is often limited to the orbital cavity and has a favorable prognosis. In some cases, the tumor can erode the orbital bone and behave as a parameningeal RMS (PM-RMS); thus, it is treated more intensively. However, the current protocols do not provide any guidance on how to consider different grades of bone erosion (BE) that can vary widely, hampering a uniform classification and the subsequent treatment assignment.

International consensus to define outcomes for trials of chemoradiotherapy for anal cancer (CORMAC-2): defining the outcomes from the CORMAC core outcome set.

Variation in outcomes definitions and reporting limit the utility of clinical trial results. The Core Outcome Research Measures in Anal Cancer (CORMAC) project developed a core outcome set (COS) for chemoradiotherapy trials for anal squamous cell carcinoma (ASCC) through an international healthcare professional and patient consensus process. The CORMAC-COS comprises 19 outcomes across 4 domains (disease activity, survival, toxicity, life impact).

Clinical and patient-reported outcomes in women offered oncoplastic breast-conserving surgery as an alternative to mastectomy: ANTHEM multicentre prospective cohort study.

Background: Oncoplastic breast-conserving surgery may be a better option than mastectomy, but high-quality comparative evidence is lacking. The aim of the ANTHEM study (ISRCTN18238549) was to explore clinical and patient-reported outcomes in a multicentre cohort of women offered oncoplastic breast-conserving surgery as an alternative to mastectomy with or without immediate breast reconstruction.

Methods: Women with invasive/pre-invasive breast cancer who were offered oncoplastic breast-conserving surgery with volume replacement or displacement techniques to avoid mastectomy were recruited prospectively.

Prospective evaluation of lung cancer screening eligibility criteria and lung cancer detection in the Yorkshire Lung Screening Trial.

Introduction: Low dose CT (LDCT) screening for lung cancer reduces lung cancer mortality, but there is a lack of international consensus regarding the optimal eligibility criteria for screening. The Yorkshire Lung Screening Trial (YLST) was designed to evaluate lung cancer screening (LCS) implementation and a primary objective was prospective evaluation of 3 pre-defined eligibility criteria.

Methods: Individuals who had ever smoked, aged 55-80yrs, who responded to written invitation, underwent telephone risk assessment and if eligible by at least one criteria (PLCO≥1.

COVID-19-sensitive tumour response: 2-year assessment of the SARS-CoV-2 humoral response in cancer patients in oncology hospital in Poland.

Unlabelled: Vaccination has been considered the most crucial defence against viral infections, including SARS-CoV-2. Numerous reports have demonstrated the effectiveness of the above vaccines in oncological patients. It has also been proven that, apart from vaccinations and oncological therapy, the course of the cancer process itself influences the magnitude of the humoral response, especially in people after infection with SARS-CoV-2.

Targeting C797S mutations and beyond in non-small cell lung cancer-a mini-review.

Non-small cell lung cancer (NSCLC) represents over 80% of lung cancer cases and has a high mortality worldwide, however, targeting common epidermal growth-factor receptor (EGFR) alterations (i.e., del19, L858R) has provided a paradigm shift in the treatment of NSCLC.
