Associations of the gut microbiome with outcomes in cervical and endometrial cancer patients treated with pembrolizumab: Insights from the phase II PRIMMO trial.

Background: The phase II PRIMMO trial investigated a pembrolizumab-based regimen in patients with recurrent and/or metastatic cervical (CC) or endometrial (EC) carcinoma who had at least one prior line of systemic therapy. Here, exploratory studies of the gut microbiome (GM) are presented.

Methods: The microbial composition of 77 longitudinal fecal samples obtained from 35 patients (CC, n = 15; EC, n = 20) was characterized using 16S rRNA gene sequencing.

Identification of potentially actionable genetic variants in epithelial ovarian cancer: a retrospective cohort study.

Ovarian cancer is the most lethal gynecologic malignancy, mainly due to late-stage diagnosis, frequent recurrences, and eventually therapy resistance. To identify potentially actionable genetic variants, sequencing data of 351 Belgian ovarian cancer patients were retrospectively captured from electronic health records. The cohort included 286 (81%) patients with high-grade serous ovarian cancer, 17 (5%) with low-grade serous ovarian cancer, and 48 (14%) with other histotypes.

Sexual health in Belgian cervical cancer survivors: an exploratory qualitative study.

Purpose: To assess experiences of sexuality and of receiving sexual healthcare in cervical cancer (CC) survivors.

Methods: A qualitative phenomenological study using semistructured one-on-one interviews was conducted with 15 Belgian CC survivors recruited in 5 hospitals from August 2021 to February 2022. The interviews were audiotaped and transcribed verbatim.

Vaginal morbidity, sexual functioning, and health-related quality of life in cervical cancer survivors: a cross-sectional multicenter study (VAMOS).

Purpose: To compare sexual/vaginal functioning between early cervical cancer (ECC) and locally advanced cervical cancer (LACC) survivors.

Methods: VAMOS was a multicenter, cross-sectional, questionnaire, noninferiority study including ECC patients treated with surgery and, if clinically indicated, adjuvant (chemo)radiotherapy and LACC patients treated with neoadjuvant (chemo)radiotherapy followed by surgery. Patient-reported outcomes (PROs) were assessed using the EORTC QLQ-C30, EORTC QLQ-CX24, and Female Sexual Functioning Index (FSFI) questionnaires.

Pembrolizumab, radiotherapy, and an immunomodulatory five-drug cocktail in pretreated patients with persistent, recurrent, or metastatic cervical or endometrial carcinoma: Results of the phase II PRIMMO study.

A phase II study (PRIMMO) of patients with pretreated persistent/recurrent/metastatic cervical or endometrial cancer is presented. Patients received an immunomodulatory five-drug cocktail (IDC) consisting of low-dose cyclophosphamide, aspirin, lansoprazole, vitamin D, and curcumin starting 2 weeks before radioimmunotherapy. Pembrolizumab was administered three-weekly from day 15 onwards; one of the tumor lesions was irradiated (8Gyx3) on days 15, 17, and 19.

Mental Health and Quality of Life among Patients with Cancer during the SARS-CoV-2 Pandemic: Results from the Longitudinal ONCOVID Survey Study.

Purpose: This longitudinal survey study aimed to investigate the self-reported outcome measures of COVID-19 peritraumatic distress, depression, anxiety, stress, quality of life (QOL), and their associated factors in a cohort of cancer patients treated at a tertiary care hospital during the SARS-CoV-2 pandemic.

Methods: Surveys were administered at four time points between 1 April 2020 and 18 September 2020. The surveys included the CPDI, DASS-21, and WHOQOL-BREF questionnaires.

Risk of Thrombo-Embolic Events in Ovarian Cancer: Does Bevacizumab Tilt the Scale? A Systematic Review and Meta-Analysis.

Thromboembolic events are the second cause of death in cancer patients. In ovarian cancer, 3-10% of patients present with venous thromboembolism (VTE), but the incidence may rise to 36% along the disease course. Bevacizumab is a monoclonal antibody directed against vascular endothelial-derived growth factor, and in in vitro studies it showed a predisposition to hemostasis perturbation, including thrombosis.

How are OCD Patients and Family Members Dealing with the Waxing and Waning Pattern of the COVID-19 Pandemic? Results of a Longitudinal Observational Study.

The current study aimed to investigate the impact of the COVID-19 pandemic on the mental health of people with OCD and the degree of family accommodation (FA) by live-in family members across phases of the lockdown measures imposed by the Belgian government. Forty-nine OCD patients and 26 live-in family members participated in the study. We assessed OCD symptom severity and FA of the live-in family members, as well as depressive symptoms, anxiety and stress levels and COVID-19 related psychological distress of patients and family members at four different timepoints: one month after the start of the lockdown (T), during the gradual relaxation (T), between the two waves (T) and during the second wave (T).

Splenic Hematopoietic and Stromal Cells in Cancer Progression.

Tumor-derived secretory factors orchestrate splenic hematopoietic and stromal cells to fuel metastasis. The spleen acts as a reservoir site for hematopoietic stem and progenitor cells, which are rapidly exploited as myeloid-derived suppressor cells at the cost of tumor-reactive lymphoid cells. Splenic erythroid progenitor cells and mesenchymal stromal cells contribute directly and indirectly to both tumor immune escape and the metastatic cascade.

Splenic F-FDG uptake on baseline PET/CT is associated with oncological outcomes and tumor immune state in uterine cervical cancer.

Objective: The spleen represents an important contributor to tumor immune escape, but the relevance of increased splenic metabolic activity remains to be fully elucidated.

Methods: We retrospectively measured the spleen-to-liver standard uptake value (SLR) on F-FDG PET/CT examinations of 92 consecutive patients with FIGO stage IB1 to IVA cervical cancer and integrated the results with survival, response to treatment, tumor immune infiltrate, and baseline characteristics.

Results: SLR > 0.

The nocebo effect and tobacco control-First, do no harm?

Since tobacco remains a leading cause of global morbidity and mortality, emphasis needs to be given to preventive approaches to tobacco consumption. Environmental and policy strategies with fear appeals are important contributors to reductions in smoking prevalence. Fear appeals are persuasive messages-often using graphic and emotionally evocative imagery and language-that attempt to scare their audiences into tobacco cessation.

Immunologic impact of chemoradiation in cervical cancer and how immune cell infiltration could lead toward personalized treatment.

We investigated the potential of tumor-infiltrating immune cells (ICs) as predictive or prognostic biomarkers for cervical cancer patients. In total, 38 patients treated with (chemo)radiotherapy and subsequent surgery were included in the current study. This unique treatment schedule makes it possible to analyze IC markers in pretreatment and posttreatment tissue specimens and their changes during treatment.

Fibroblasts Fuel Immune Escape in the Tumor Microenvironment.

Immune escape is central to the persistence of most, if not all, solid tumors and poses a critical obstacle to successful cancer (immuno)therapy. Cancer-associated fibroblasts (CAFs) constitute the most prevalent, yet heterogeneous, component of the tumor stroma, where they 'cool down' the immune microenvironment. The central role played by CAFs, both as a physical barrier and source of immunosuppressive molecules, sets them as a target to enhance immunotherapy of cancer.
