Background: Supporting cancer survivors in self-management can empower them to take an active role in managing the long-term physical and psychosocial consequences of cancer treatment. Healthcare practitioners are key to supporting patients to self-manage, however, they do not routinely engage in these discussions. This review aimed to establish what works for whom and in what circumstances in relation to facilitating healthcare practitioners to provide self-management support in people living with long-term consequences of cancer treatment., Methods: The review follows five steps: define the review's scope, develop initial programme theories, evidence search, selection and appraisal, and data extraction and synthesis. Database searches of Medline, EMBASE, CINAHL, Scopus, PsycINFO, ERIC and AMED databases, to September 2019 were supplemented with practitioner surveys. Insights into the mechanisms that operate in particular contexts to produce successful outcomes were illustrated using realist programme theories, developed using the Theoretical Domains Framework. Data selection was based on relevance and rigour. Data were extracted and synthesised iteratively to illuminate causal links between contexts, mechanisms and outcomes., Results: Five programme theories were identified from 20 included articles and seven practitioner surveys: practitioners will engage patients in discussions about self-management if they have appropriate (1) knowledge and (2) consultations skills, (3) a clear understanding of their self-management support role and responsibilities, and if (4) organisational strategies and (5) health system configuration enable integration into routine care. The mechanisms facilitating practitioners to support self-management were practitioner confidence, mutual trust and shared responsibility between practitioners and cancer survivors, organisational prioritisation and ease of delivery of self-management support., Conclusion: The findings articulate the necessary components for embedding self-management support into routine cancer care. Operationalisation of these components into effective self-management support interventions will require reconfiguration of pathways and adaptation for local context, using strategies such as quality improvement and co-design to guide intervention development, implementation and evaluation., Competing Interests: Declaration of competing interest None., (Copyright © 2022 The Authors.

Prostate cancer is one of the leading causes of cancer related death in men, and remains incurable in the metastatic setting. Despite the initial response to androgen deprivation, the disease gradually progresses to a hormone-refractory state due to cumulative genetic alterations in tumour cells or the microenvironment. Docetaxel represents the first chemotherapeutic agent with a small survival benefit for metastatic hormone-refractory prostate cancer (HRPC). In an attempt to improve survival benefit, several novel drugs targeting specific pathways involved in cell signaling, proliferation, angiogenesis, apoptosis and immune modulation are currently under investigation either as single agents or in combination with cytotoxic drugs. Clinical trials evaluate the inhibition of prostate cancer cells growth by targeting the nuclear receptor of vitamin D alongside cytotoxic therapy. Angiogenesis inhibitors as well as epidermal growth factor receptor blockage are also under clinical investigation in several combinations. Immunomodulatory agents and autologous dendritic cells or allogenic whole cell vaccines have progressed up to phase III trials. New drugs targeting bone microenvironment or apoptotic and proliferation pathways may enhance antitumour activity of chemotherapy in HRCP. Given the complexity of mechanisms underlying prostate cancer progression, future therapeutic strategies should rely on multidisciplinary approaches, thus exploiting newer molecular targets in concert with immunotherapy and cytotoxic chemotherapy. Here, we review the latest clinical evidence regarding the use of novel agents in HRPC., (Copyright (c) 2009 Elsevier Ltd. All rights reserved.)

The percentage of elderly people with head and neck cancers (HNC) is rising due to increasing average lifespan. As with younger patients, elderly patients require a multidisciplinary approach in order to optimise treatment results. The biological, not the chronological, age should be defined individually based on co-morbidities and performance status. A comprehensive geriatric assessment represents the first and essential step for selecting further treatment options. Major improvements have been accomplished in surgical techniques and radiotherapy delivery. Several chemotherapeutic agents and targeted therapies with different toxicity profile are also available. However, the randomised studies that defined the nature of these improvements included only a small proportion of patients older than 65 years. In deciding which treatment strategy would be suitable for an individual elderly patient, we review the literature regarding surgery, radiotherapy, and chemotherapy or their various combinations.

Mammalian target of rapamycin (mTOR) is a key protein kinase controlling signal transduction from various growth factors and upstream proteins to the level of mRNA and ribosome with a regulatory effect on cell cycle progression, cellular proliferation and growth. TOR genes were discovered rather serendipitously while investigating the cause of resistance to immunosuppressant rapamycin in yeast. In normal cells, mTOR controls brilliantly the load of signals from its effectors resulting in a normal cell function. On the contrary, in various diseases and mainly in cancer this balance is lost due to mutations or overactivation of upstream pathways leading to a persistent proliferation and tumor growth. What makes mTOR attractive to researchers seems to be its key position which is on the crossroad of various signal pathways (Ras, PI3K/Akt, TSC, NF-kappaB) towards mRNA, ribosome, protein synthesis and translation of significant molecules, the uncontrolled production of which may lead to tumor proliferation and growth. Inhibition of mTOR by rapamycin (a natural product) or its analogs aims to prevent the deleterious effects of the abnormal signaling, regardless at which point of the signal pathway has the abnormality launched. Here, we will review the physiological functions of mTOR, its association to carcinogenesis and the latest evidence regarding the use of mTOR inhibitors in cancer treatment as well as future trends and aims of research.

Background: We recorded the epidemiologic and clinical features of hypersensitivity reactions (HSRs) to oxaliplatin in colorectal cancer (CRC) patients in order to provide information on the management of these patients. We also developed a desensitization protocol and evaluated its clinical application. For these reasons, we analyzed retrospectively the records of 215 CRC patients treated with oxaliplatin-containing regimens either as an adjuvant, first-line, second-line, or more., Patients and Methods: Data from 52 patients with HSRs were analyzed according to the Common Toxicity Criteria for Adverse Events (CTCAE), v3.0. Three patients were chosen for the desensitization protocol. After determining the starting point for desensitization, we applied the standard protocol for parenteral desensitization to b-lactam antibiotics. Oxaliplatin treatment was then carried out with serial 10-fold dilutions in sufficient volume to administer the total dose. A total of 52 patients (24.2%) were recorded as having an allergic reaction to oxaliplatin., Results: Hypersensitivity reactions were recorded after a mean of 6.5 (SD +/- 4.5) cycles. Only 4 patients (4 of 215; 1.8%) developed CTCAE grade 3/4 HSRs. Hypersensitivity reactions were seen more likely in patients receiving second-line or more of chemotherapy compared with chemotherapy-naive patients. No other correlations were seen (the presence of atopic disease, positive skin prick test). The 3 patients, having completed the parenteral desensitization protocol, completed their treatment uneventfully as well., Conclusion: Hypersensitivity reactions from oxaliplatin respond quickly to the discontinuation of the drug and appropriate support. Premedication and an increased infusion time could allow for readministration. The desensitization protocol we developed can provide a reliable alternative to permanent discontinuation of oxaliplatin.

The human epidermal growth factor receptor (EGFR) signaling is overexpressed in many solid malignancies, making it an appealing target for biologic agents. A number of agents that target this receptor are in use or in development. A specific adverse effect common to this class of agents is an acneiform-like skin rash that has been related to EGFR inhibition in the skin. Little is known about the etiology of this rash, and there are no clear evidence-based management recommendations. Findings suggest that there is a relationship between the development of rash and response and/or survival, making rash a potential surrogate marker of activity. This review summarizes and updates the current knowledge of the clinical presentation, etiology, and predictive and prognostic value of erlotinib-induced skin rash and establishes a treatment strategy to help treat dermatologic adverse events and allow patients to continue therapy without dose interruption or drug discontinuation.
