Background: Epithelioid trophoblastic tumor (ETT) is a rare and newly defined disease, which most commonly occurs in women of reproductive age and can be a sequela of any gestational event. ETT can be present in both intrauterine and extrauterine sites. Case report: A woman of reproductive age, without specific comorbidities and with a single pregnancy and natural childbirth eight years ago, was diagnosed initially with poorly differentiated pleomorphic leiomyosarcoma on the hemostatic uterine curettage. Conclusion: Our case highlights that ETT presents a diagnostic challenge due to its rarity and histologic resemblance to other pathologies. Misdiagnosis delays effective treatment and affects survival. To date, only 8 cases of ETT of the uterus without previous gestational event and normal human chorionic gonadotropin (β-HCG) levels in a 60-year literature survey have been reported.
IntroductionAn accessible and affordable way to deliver behavior change programs to a large proportion of the growing community of cancer patients and survivors is through web-based methods of nutritional counselling.ObjectiveThe aim of this systematic review was to evaluate the effectiveness of web-based nutritional therapies targeting physical activity, diet, and/or weight control for cancer patients or survivors, primarily disseminated via modern technologies (mobile phone applications) or online.Materials and methodsThe authors conducted a structured search of the PubMed database. Studies that have focused on physical activity (PA) and dietary change and/or weight control in adolescent and adult cancer patients and survivors have reported outcomes conducted via a broad modality.ResultsNine articles focused on web-based nutrition for patients with cancer and cancer survivors. They were conducted in the United States, Australia, Korea, China, and in the United Kingdom, and were published between 2018 and 2022 in a variety of scientific journals. The number of participants ranged from 20 to 159.ConclusionWeb-based nutrition counselling helps cancer patients and survivors improve their dietary intake, impacts their weight and quality of life, and promotes a healthy lifestyle. Future research should evaluate (1) the differences in cost and coverage between face-to-face and web-based nutrition, (2) long-term outcomes, (3) cost-effectiveness, and last but not least, (4) the effectiveness of web-based nutrition in adolescents and children who suffer from cancer or who survived cancer, as nutritional status and body composition have a marked impact on clinical outcomes during and after treatment. The strength of this review lies in the large number of randomized controlled trials, which offer a guarantee of effectiveness and objectivity compared to cross-sectional studies.
Background and Objectives: Cannabinoids are currently used in cancer patients primarily for their pain-relieving and antiemetic properties. The aim of our review was to synthesize all available data of studies evaluating the therapeutic efficacy of cannabis in combination with oncological treatments in cancer patients and to explore ongoing studies with different goals and medical areas registered in the field of oncology worldwide. Materials and Methods: This study was performed in accordance with the PRISMA guidelines. A search using MEDLINE/PubMed database was performed between 1 January 2006 and 1 March 2022. Search terms included the following: cannabidiol, cannabis, CBD, dronabinol, endocannabinoids, medical marijuana, nabiximols, nabilone, THC, and cancer. All studies that examined the efficacy of cannabis administered during oncological treatments, regardless of cancer localization, subtype, and sample size, were considered eligible. Results: In three studies, cannabis was administered to patients with glioblastoma, and in two other studies, cannabis was used in combination with immunotherapy in various cancer subgroups. The results of the clinical trials in cancer patients are not sufficient to draw conclusions at this time. Interestingly, several other studies addressing the systemic effects of cannabinoids in cancer patients are currently listed in the U.S. National Library of Medicine’s registry on the ClinicalTrials.gov website. However, only one of the registered studies examined the efficacy of cannabinoids as a potential option for systemic cancer treatment. Conclusions: Although cannabis is touted to the public as a cancer cure, clinical trials need to clarify which combinations of chemotherapeutic agents with cannabinoids are useful for cancer patients.
The treatment of terminally ill patients raises many dilemmas that make it difficult to draw a line between treatment of uncertain benefits and therapeutic utility. Aim: To synthesize the qualitative and quantitative evidence on the views, experiences and perceptions of doctors and nurses from different specialties involved in the care of people nearing the end of life in relation to therapeutic obstinacy and futility. Design: Systematic review and narrative synthesis of qualitative and quantitative studies. Data sources: PubMed, PsycINFO, the International Association for Hospice and Palliative Care/Cumulative Index of Nursing and Allied Health Literature [IAHPC/CINAHL], and Communication & Mass Media Complete [CMMC] databases. Review methods: Databases were searched for studies from May 2016 to November 2021. Pediatric studies, family/relative viewpoints, advance care directives, and euthanasia studies were excluded. Results were synthesized using a narrative synthesis approach with thematic analysis. Results: 8 studies were included. Conclusion: Despite different perceptions among health professionals, the complexity of supporting therapy obstinacy and futile therapies lead to burnout, professional dissatisfaction and impaired communication skills among health professionals. Impact: This review will be of interest to palliative care, oncology and critical care practitioners and those planning to train and practice in these fields and will also provide inputs to debates on ethical issues in end-of-life care.
Prior to the COVID-19 pandemic, vaccination of people with cancer or a recent history of cancer was advisable under specific conditions, depending on the type of vaccine (inactivated or live attenuated virus or bacterium), type of cancer, and whether they had undergone treatment for cancer. Some malignancies, especially hematological malignancies, and cancer treatments such as chemotherapy, radiotherapy, and splenectomy negatively impact the immune response. The clinical trials of currently used vaccines against COVID-19 did not include people with active cancer; thus, there is an important gap in the knowledge of safety and efficiency data for COVID-19 immunization in this population. However, considering the risk of mortality and morbidity due to possible infection with SARS-CoV-2, medical experts recommend immunization on an individual basis. As the worldwide prevalence of malignancies is high, reliable information on COVID-19 vaccination is expected to be revealed in future clinical trials. In this review, we examine the key aspects of cancer that may be affected by COVID-19 and summarize the current literature on COVID-19 immunization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
