Esophageal adenocarcinoma is an aggressive cancer of increasing incidence and is associated with poor prognosis. The early recognition of synchronous and metachronous oligometastasis in esophageal adenocarcinoma may allow for prompt intervention and potentially improved survival. However, curative approaches to oligometastatic esophageal disease remain unproven and may represent an area of emerging divergence of opinion for surgical and medical oncologists. We sought to identify the current understanding and evidence for management of oligometastatic esophageal adenocarcinoma by performing a thorough review of the available literature.

Abstract Introduction: Glioblastoma is an aggressive cancer with a notoriously poor prognosis. Recent advances in treatment have increased overall survival, though this may be accompanied by an increased incidence of leptomeningeal disease (LMD). LMD carries a particularly severe prognosis and remains a late stage manifestation of glioblastoma without satisfactory treatment. The objective of this review is to survey the literature on treatment of LMD in glioblastoma and to more fully characterize the current therapeutic strategies. Methods: The authors performed a systematic review following PRISMA criteria on PubMed. Articles that included adult patients with LMD from glioblastoma multiforme were retrieved and reviewed. Results: LMD in glioblastoma patients is increasing in incidence, with reports of up to 21%. The overall survival without treatment is alarmingly brief, with patients surviving between 1.6-3.8 months. All studies showed that treatment does improve overall survival significantly, increasing to 11.7 months in one study. However, no one adjuvant or surgical therapy has been shown to improve survival in LMD significantly over another. Direct treatment methods include chemotherapy (standard, anti-angiogenic, intrathecal, immunotherapy), and radiation. Hydrocephalus is a complication in LMD that can be treated with ventriculoperitoneal shunt placement, however treating hydrocephalus and delivering intrathecal chemotherapy is a challenge. Conclusion: Though evidence remains lacking and there is no consensus, treatments show a trend towards improving survival and should be considered on a case-by-case basis. Further studies are necessary in the pursuit of a standard of care.

Macrophages are the most important phagocytes in vivo. However, the tumor microenvironment can affect the function and polarization of macrophages and form tumor-associated macrophages (TAMs). Usually, the abundance of TAMs in tumors is closely associated with poor prognosis. Preclinical studies have identified important pathways regulating the infiltration and polarization of TAMs during tumor progression. Furthermore, potential therapeutic strategies targeting TAMs in tumors have been studied, including inhibition of macrophage recruitment to tumors, functional repolarization of TAMs toward an antitumor phenotype, and other therapeutic strategies that elicit macrophage-mediated extracellular phagocytosis and intracellular destruction of cancer cells. Therefore, with the increasing impact of tumor immunotherapy, new antitumor strategies to target TAMs are now being discussed.

Release of immunoreactive negative regulatory factors such as immune checkpoint limits antitumor responses. PD-L1 as a significant immunosuppressive factor has been involved in resistance to therapies such as chemotherapy and target therapy in various cancers. Via interacting with PD-1, PD-L1 can regulate other factors or lead to immune evasion of cancer cells. Besides, immune checkpoint blockade targeting PD-1/PD-L1 has promising therapeutic efficacy in the different tumors, but a significant percentage of patients cannot benefit from this therapy due to primary and acquired resistance during treatment. In this review, we described the utility of PD-L1 expression levels for predicting poor prognosis in some tumors and present evidence for a role of PD-L1 in resistance to therapies through PD-1/PD-L1 pathway and other correlating signaling pathways. Afterwards, we elaborate the key mechanisms underlying resistance to PD-1/PD-L1 blockade in cancer immunotherapy. Furthermore, promising combination of therapeutic strategies for patients resistant to PD-1/PD-L1 blockade therapy or other therapies associated with PD-L1 expression was also summarized.

Pulmonary angiosarcoma is a rare clinical entity with a poor prognosis and no established therapeutic strategies. We present the first case to our knowledge of metastatic pulmonary angiosarcoma, treated with checkpoint inhibitor immunotherapy, and have an excellent response. Until now, patient has been treated with immunotherapy for 1 year, and his disease is stable and well-tolerated.

The rates of liver disease in the UK are rising and hence more patients than ever are presenting to acute medical units with potentially life threatening sequelae. Early recognition and treatment of sepsis, kidney injury, bleeding and alcoholic hepatitis can significantly improve outcomes, but requires a comprehensive approach to assessment. This patient cohort often suffers from a perceived uniform poor prognosis, especially in alcohol related disease, but evidence for this is changing and reassessment of prognosis after 48 hours of organ support may be more accurate than that made ‘at the front door’. This article summarises the most important complications of decompensated cirrhosis, their early management, and presents a targeted system of care: ‘RING Liver’ – Renal failure, Infection, Nutrition, Gastrointestinal bleeding and transit, Liver dysfunction/transplantation. Factors favouring transfer to tertiary units are also explored.

Autophagy is a multistep catabolic process through which misfolded, aggregated or mutated proteins and damaged organelles are internalized in membrane vesicles called autophagosomes and ultimately fused to lysosomes for degradation of sequestered components. The multistep nature of the process offers multiple regulation points prone to be deregulated and cause different human diseases but also offers multiple targetable points for designing therapeutic strategies. Cancer cells have evolved to use autophagy as an adaptive mechanism to survive under extremely stressful conditions within the tumor microenvironment, but also to increase invasiveness and resistance to anticancer drugs such as chemotherapy. This review collects clinical evidence of autophagy deregulation during cholangiocarcinogenesis together with preclinical reports evaluating compounds that modulate autophagy to induce cholangiocarcinoma (CCA) cell death. Altogether, experimental data suggest an impairment of autophagy during initial steps of CCA development and increased expression of autophagy markers on established tumors and in invasive phenotypes. Preclinical efficacy of autophagy modulators promoting CCA cell death, reducing invasiveness capacity and resensitizing CCA cells to chemotherapy open novel therapeutic avenues to design more specific and efficient strategies to treat this aggressive cancer.

Previously considered to be rare, malignant pleural mesothelioma (MPM) is a highly aggressive tumour that has become a very important issue over recent years due to its poor prognosis and its increasing incidence mostly linked to previous asbestos exposure. An optimal treatment for MPM is not established yet; new therapies and predictive tools are still needed in the management of this cancer. Thus the aim of this review is to provide clinicians clear and up-to-dated data on the latest therapeutic strategies for MPM patients in 2010. The guidelines recently proposed by the European Respiratory Society (ERS) and the European Society of Thoracic Surgeons (ESTS) taskforce are summarized here. The authors also briefly reviewed the future directions in MPM treatment including targeted therapies, gene or cell therapies.

Malignant pleural mesothelioma (MPM) is an aggressive cancer, associated with poor prognosis. We assessed the feasibility of patient-derived cell cultures to serve as an ex vivo model of MPM. Patient-derived MPM cell cultures (n=16) exhibited stemness features and reflected intratumour and interpatient heterogeneity. A subset of the cells were subjected to high-throughput drug screening and coculture assays with cancer-specific cytotoxic T cells and showed diverse responses. Some of the biphasic MPM cells were capable of processing and presenting the neoantigen SSX-2 endogenously. In conclusion, patient-derived MPM cell cultures are a promising and faithful ex vivo model of MPM.
