Malignant Pleural Mesothelioma (MPM) is currently an incurable cancer with a typical survival of 1 year from the time of diagnosis. The recent genomic and transcriptomic characterization of MPM presents new opportunities and challenges for MPM researchers. Recent advances in clinical and laboratory diagnostics, and proposals for an updated, data-driven, staging system, also present new challenges for clinicians and hospital services involved in MPM care. The aim of this review is first to introduce the reader to the topic of MPM, a disease that is causally linked to prior, typically occupational, exposure to asbestos fibres...

BACKGROUND: Extended postoperative chemoprophylaxis is effective in reducing venous thromboembolism (VTE) among general surgical patients. We hypothesized that implementation of the Caprini risk assessment model (RAM) would reduce VTE rates among patients undergoing lung and esophageal cancer surgery. METHODS: The Caprini RAM, consisting of patient risk stratification and extended postoperative chemoprophylaxis with low molecular weight heparin, was implemented on the thoracic surgery service at Boston Medical Center in July 2014...

BACKGROUND: Venous thromboembolism (VTE) remains a serious complication after the surgical treatment of breast cancer. Contemporary guidelines limit VTE chemoprophylaxis to the period of hospitalization. We conducted this study to evaluate the frequency of postdischarge VTE among surgically treated breast cancer patients and identify patient level factors associated with postdischarge VTE. METHODS: Using Arkansas, Florida, Nebraska, and New York state inpatient databases, we conducted a retrospective cohort study of adult women who underwent surgical treatment for breast cancer between October 1, 2008, and September 30, 2013...

Background: Antimicrobial prophylaxis is indicated to prevent Pneumocystis jirovecii pneumonia (PJP) in profoundly immunosuppressed children. The incidence of PJP infection in children with chronic glucocorticoid exposure is unknown, and PJP prophylaxis has been associated with adverse events. We hypothesized that PJP infection is rare in children without human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), cancer, or a transplant history who are using chronic glucocorticoids and that those exposed to PJP prophylaxis are more likely to experience a cutaneous hypersensitivity reaction or myelosuppression than unexposed patients...

We evaluated the efficacy of single-dose instillation of pirarubicine hydrochloride (THP) in the chemoprophylaxis of non-muscle-invasive bladder cancer(NMIBC). In a retrospective study, 135 evaluable patients were assigned to three groups after transurethral resection of bladder tumors (TURBT). In group 1, patients received no adjuvant therapy after TURBT. In group 2, patients received a single-dose of 30 mg THP in 30 ml normal saline immediately after TURBT. In group 3, patients received 30 mg THP in 30 ml normal saline 2 weeks after TURBT , and the instillations were repeated for 4 weeks, then every other week twice and successively monthly for 6 months...

BACKGROUND: Constitutional mismatch repair deficiency syndrome results from bi-allelic inheritance of mutations affecting the key DNA mismatch repair genes: MLH1, MSH2, MSH6 or PMS2. Individuals with bi-allelic mutations have a dysfunctional mismatch repair system from birth; as a result, constitutional mismatch repair deficiency syndrome is characterised by early onset malignancies. Fewer than 150 cases have been reported in the literature over the past 20 years. This is the first report of the founder PMS2 mutation - NM_000535...

Venous thromboembolism (VTE) is a common medical condition, particularly after surgical interventions. Many studies have shown that development of VTE, including both deep vein thrombosis (DVT) and pulmonary embolism (PE), is more common in surgical patients with cancer than in patients without cancer. This chapter focuses on VTE in brain tumor patients, including their pathogenesis, presentation, diagnosis, and treatment. Topics discussed included a brief overview of VTE followed by an in-depth discussion of the VTE risks brain tumor patients face in the post-operative period...

The incidence of cutaneous squamous cell carcinomas (SCCs) in immunosuppressed solid organ transplant recipients (SOTRs) is 65- to 250-fold greater than in the general population. In addition, SCC in SOTRs is more aggressive than in the general population. SOTRs must undergo skin cancer screenings at intervals based on their risk stratification. The incidence of SCC in SOTRs varies with the type, intensity, and duration of the immunosuppressive regimen. Notably, patients on sirolimus have lower incidence of SCC compared to patients on calcineurin inhibitors...

BACKGROUND: People who travel while immunocompromised are more at risk of serious travel-related infection. Their condition, medications or treatments can contraindicate, decrease the effectiveness of or increase the toxicity of vaccinations or malaria chemoprophylaxis. Therefore, immunocompromised travellers require careful assessment and specialized pre-travel advice. The aims of this study were to investigate enquiries by healthcare professionals (HCPs) to the UK National Travel Health Network and Centre (NaTHNaC) advice line regarding travellers with immunocompromise and to identify their most common concerns...

BACKGROUND: We prospectively evaluated the safety and efficacy of adding preoperative chemoprophylaxis to our institution's operative venous thromboembolism (VTE) prophylaxis policy as part of a physician-led quality improvement initiative. STUDY DESIGN: Patients undergoing major cancer surgery between August 2013 and January 2014 were screened according to service-specific eligibility criteria and targeted to receive preoperative VTE chemoprophylaxis. Bleeding, transfusion, and VTE rates were compared with rates of historical controls who had not received preoperative chemoprophylaxis...

Bladder cancer has high prevalence in men and women. Bladder cancer usually originates from urothelium. More than 75% of cases are classified as nonmuscle invasive bladder cancer. Urothelial bladder carcinoma is usually managed by transurethral resection of the bladder tumor. Role of transurethral resection of the bladder tumor is also essential in bladder cancer staging. Local prophylaxis is used in nonmuscle invasive bladder cancer to reduce risk of recurrence. While local chemoprophylaxis is sufficient in low and middle risk patients, intravesical instillation of Mycobacterium bovis bacillus CalmetteGuerin (BCG) is preferred in high risk bladder cancer...

BACKGROUND: Current guidelines for gastrointestinal cancer surgical intervention in high-risk patients recommend postoperative venous thromboembolism (VTE) chemical prophylaxis for 4 weeks with low-dose unfractionated heparin or low-molecular-weight heparin, but specific guidelines for esophagectomy are lacking. This survey identified the clinical patterns affecting postesophagectomy VTE chemoprophylaxis use among general thoracic surgeons. METHODS: General Thoracic Surgery Club members were invited to complete an online survey on VTE prophylaxis to analyze clinical factors affecting their choices...

OBJECTIVE: Postoperative venous thromboembolism (VTE) creates an 8-fold increase in mortality after lung resection. About one third of postoperative VTEs occur after discharge. The Caprini risk assessment model has been used by other specialties to calculate the risk of a VTE. Patients deemed high risk by the model are candidates for prophylactic anticoagulation after discharge, reducing the VTE risk by 60%. Our primary aims were to determine the frequency of VTE events and evaluate whether the Caprini model could risk-stratify patients...

Pneumocystis pneumonia (PCP) is a life-threatening infection in immunocompromised patients. It is relatively uncommon in patients with lung cancer. We report a case of PCP in a 59-year-old man with a past medical history of chronic obstructive pulmonary disease treated with formoterol and a moderate daily dose of inhaled budesonide. He had also advanced stage non-small lung cancer treated with concurrent chemo-radiation with a cisplatin-etoposide containing regimen. The diagnosis of PCP was suspected based on the context of rapidly increasing dyspnea, lymphopenia and the imaging findings...

PURPOSE: Hemorrhagic cystitis is an important dose limiting side effect of ifosfamide based cancer chemotherapy. Despite chemoprophylaxis inflammation can still be found in cystoscopy guided biopsies. Previous studies confirmed the role of TNF-α and IL-1β. We evaluated the protective effect of the IL-1R antagonist anakinra and the anti-TNF-α antibody infliximab in experimental ifosfamide induced hemorrhagic cystitis. MATERIALS AND METHODS: Hemorrhagic cystitis was induced by an injection of ifosfamide (400 mg/kg intraperitoneally) in Swiss wild-type C57Bl/6, IL-1R-/-, TNFR1-/- or TNFR1/R2-/- mice...

BACKGROUND: Current guidelines recommend postoperative venous thromboembolism (VTE) chemoprophylaxis for moderate-risk patients (3% rate or greater) and extended-duration chemoprophylaxis for high-risk patients (6% or greater). Large-scale studies of and recommendations for esophagectomy patients are lacking. This study was designed to evaluate the timing, rates, and predictors of postesophagectomy VTE. METHODS: Patients undergoing esophagectomies for cancer were identified from the 2005 to 2012 American College of Surgeons National Surgical Quality Improvement database...
