Pancreatic ductal adenocarcinoma is a highly aggressive malignancy with a poor prognosis. Effective treatment with acceptable outcomes is yet to be found, with chemo- and radioresistance comprising major impediments towards this goal. Although upfront surgery is the established therapeutic approach for resectable and borderline resectable disease, neoadjuvant treatment has recently monopolized the interest in clinical trials. This also applies to locally advanced pancreatic adenocarcinomas that could potentially be rendered operable. Chemotherapy and chemoradiotherapy are the most utilized therapeutic modalities in the neoadjuvant setting, while immunotherapy and targeting agents have been gaining significant attention. This critical review focuses on the clinical experience gained from retrospective and phase II/III randomized trials, reporting on the outcomes of neoadjuvant chemotherapy and chemoradiotherapy for pancreatic adenocarcinoma. Moreover, the ongoing trials, including those that involve immunotherapy and targeting agents, are summarized.
Introduction: Bone cancer causes a significant mental health burden. Although the mental health implications of cancer as a whole have been widely discussed, there is limited evidence regarding the psychiatric and psychological sequelae of malignant and benign bone neoplasms in particular.
Purpose: To summarize the scientific literature, present relevant knowledge gaps and discuss a number of recommendations. Methodology: The authors searched Pubmed/Medline and Google Scholar with keywords (mental health, bone cancer, musculoskeletal neoplasms, psychiatric comorbidities). When appropriate, MeSH terms and Boolean operators were used. Relevant peer reviewed studies published in English, French or German until 05 May 2021 were included.
Results and Discussion: Loss of mobility, decrease of physical activity, chronic pain and amputations in combination with patient’s previous psychiatric history, socioeconomic conditions, cancer biology and treatment-related side effects undermine the mental wellbeing of patients and carers. Since March 2020, the COVID-19 pandemic has posed an additional burden, which is yet to be comprehensively evaluated.
Conclusion: More research and solid action towards the integration of mental health care into the management of bone cancer is crucial
Neoadjuvant chemotherapy (NACT) for certain breast cancer (BC) subtypes confers significant tumor regression rates and a survival benefit for patients with a complete pathologic response. Clinical and preclinical studies have demonstrated that immune-related factors are responsible for better treatment outcomes, and thus, neoadjuvant immunotherapy (IO) has emerged as a means to further improve patient survival rates. Innate immunological “coldness”, however, of specific BC subtypes, especially of the luminal ones, due to their immunosuppressive tumor microenvironment, hinders the efficacy of immune checkpoint inhibitors. Treatment policies aiming to reverse this immunological inertia are, therefore, needed. Moreover, radiotherapy (RT) has been proven to have a significant interplay with the immune system and promote anti-tumor immunity. This “radiovaccination” effect could be exploited in the neoadjuvant setting of BC and significantly enhance the effects of the already established clinical practice. Modern stereotactic irradiation techniques directed to the primary tumor and involved lymph nodes may prove important for the RT-NACT-IO combination. In this review, we provide an overview and critically discuss the biological rationale, clinical experience, and ongoing research underlying the interplay between neoadjuvant chemotherapy, anti-tumor immune response, and the emerging role of RT as a preoperative adjunct with immunological therapeutic implications in BC.
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.
