Abstract
BackgroundThe impact of immunosuppressants on COVID-19 vaccination response and durability in patients with immune-mediated inflammatory diseases (IMID) is yet to be fully characterized. Humoral response may be attenuated in these patients especially those on B cell depleting therapy and higher doses of corticosteroids, but data regarding other immunosuppressants are scarce.ObjectivesWe aimed to investigate antibody and T cell responses and durability to SARS-CoV-2 mRNA vaccines (BNT162b and/or mRNA 1273) in IMID patients on immunomodulatory maintenance therapy other than B-cell depleting therapy and corticosteroids.MethodsThis prospective observational cohort study examined the immunogenicity of SARS-CoV-2 mRNA vaccines in adult patients with IMIDs (psoriatic arthritis, psoriasis, inflammatory bowel disease and rheumatoid arthritis) with or without maintenance immunosuppressive therapies (anti-TNF, methotrexate/azathioprine [MTX/AZA], anti-TNF + MTX/AZA, anti IL12/23, anti-IL-17, anti-IL23) compared to healthy controls. Automated ELISA for IgGs to spike trimer, spike receptor binding domain (RBD) and the nucleocapsid (NP) and T-cell release of 9 cytokines (IFNg, IL2, IL4, IL17A, TNF) and cytotoxic molecules (sFasL, GzmA, GzmB, Perforinin) in cell culture supernatants following stimulation with spike or NP peptide arrays were conducted at 4 time points: T1=pre vaccination, T2=median 26 days after dose 1, T3=median 16 days after dose 2 and T4=median 106 days after dose 2. Neutralization assays against four SARS-CoV-2 variants (wild type, delta, beta and gamma) were conducted at T3.ResultsWe followed 150 subjects: 26 healthy controls and 124 IMID patients: 9 untreated, 44 on anti-TNF, 16 on anti-TNF with MTX/AZA, 10 on anti-IL23, 28 on anti-IL12/23, 9 on anti-IL17, 8 on MTX/AZA (Table 1). Most patients mounted antibody and T cell responses with increases from dose 1 to dose 2 (100% seroconversion at T3) and some decline by T4, with variability within groups. Antibody levels and neutralization efficacy was lower in anti-TNFgroups (anti-TNF, anti-TNF + MTX/AZA) compared to controls and waned by T4 (Figure 1). T cell responses were not consistently different between groups. Pooled data showed a higher antibody response to mRNA-1273 compared to BNT162b.Table 1.Baseline characteristics of study participantsControluntreated IMIDAnti- TNFAnti- TNF +MTX/AZAAnti-IL-23Anti -IL-12/23Anti -IL-17MTX/AZAn=26n=9n=44n=16n=10n=28n=9n=8p-valueIMID*N/A IBD9301002704 Psoriasis1318122 PA0732172 AS0830010 RA1100011Age median years [IQR]36 [26-46]33 [27-41]38 [30-51]53 [44-59]48 [45-61]34 [28-47]49 [46-61]42 [31-55]<0.001^Sex male (%)16 (62)5 (56)18 (41)8 (50)5 (50)13 (46)6 (67)4 (50)0.772~BMImedian kg/m2 [IQR]25 [23-28]26 [22-27]22 [24-26]26 [24-28]27 [24-35]22 [21-24]32 [26-34]26[25-33]0.001^Vaccine interval median days [IQR]74 [35-84]54 [31-64]60 [45-69]64 [50-72]74 [35-84]62 [49-69]65 [52-75]58 [21-97]0.372^*multiple IMIDs per patient possibleFigure 1.Antibody responses (A) Anti spike and anti RBD IgG levels at indicated time points.

Abstract
In the US, many people are excluded from healthcare structures and systems, due to multiple macro and micro factors. Poverty, health ecosystems, mental health, and community amenities are some of the issues confronting those who are not able to access appropriate support. This population is often referred to as 'high needs, high cost' (HNHC), a term that has been applied to refer to people who repeatedly utilize services without significant benefit (we have replaced this term with 'currently under-served'; C-US). For many traditional health solutions may not address the fundamental issues confronting their health. Community-Engaged Healthcare (CEH) is an approach that equips members of the community to levy power to advocate for their own health or social solutions, designing their own interventions to address needs with support from health providers. A realist review was conducted to identify the existing literature around CEH. This yielded ten papers that were reviewed by at least two authors and rated in terms of quality. A model describing the processes underpinning CEH was then iteratively generated, resulting in additional terms that were used in a second review of the literature. A further 16 peer-reviewed articles were identified and were independently reviewed and quality rated. These articles were used to refine further iterations of the model and included in the review where appropriate. The resulting model schematically posits a set of relational factors identified to be important in the establishment of CEH. Notably, the transfer of autonomy and power over health decision-making processes is emphasized, which will require revolutionary thinking about how healthcare is delivered for patients.

Abstract
Introduction The process of adjustment to disability and illness among people with chronic illness and disabilities (CID) impacts on motivation for rehabilitation illness self-management, and psychological well-being. It involves a complex interplay of biopsychosocial factors, and was seldom examined in the Chinese context. Objectives Identify the predictors of mental well-being of people with from a set of variables including illness and social support, functional abilities, coping strategies, resilience. Examine how these factors interact in determining psychosocial adaptation and mental well-being by structural equations modelling (SEM). Methods We conducted a survey of people with CID, who were recruited from community-rehabilitation settings and self-help groups (N = 244). The research questionnaire collected basic demographic information, illness-related variables (e.g. pain, fatigue, functional limitations), and RIDI), social support, measures of resilience, coping, psychosocial ad as predictors, and mental well-being. Results Of General Linear Model (GLM) revealed that males have better adaptation than females. Resilience, social coping, & active problem solving are significant predictors of adaptation (Table 1), while age, breathing, pain, resilience, avoidance coping, are predictors of maladaptation (Table 2). A SEM was tested to examine the interaction among the predictors and outcome of adaptation and mental well-being (Figure 1), and the model fit was fair (CFI = 0.89; RMSEA = 0.09) Conclusions The results indicated that there are gender differences in adaptation. While all the hypothesized groups of variables contributed to mental well-being of people with CID. Resilience, illness variables, and some forms of coping are closely linked to adaptation and maladaptation. Disclosure No significant relationships.

Abstract
Background In Ontario, no clearly defined standard of care for the management of mantle cell lymphoma (mcl) has been developed, and substantial variability from centre to centre is evident. This guidance document was prompted by the need to harmonize practice in Ontario with respect to first-line, conditioning, and post-transplantation maintenance therapy for patients newly diagnosed with transplantation-eligible mcl. Methods The medline and embase databases were systematically searched from January 2013 to January 2020 for evidence, and the best available evidence was used to draft recommendations relevant to first-line therapy, autologous stem-cell transplantation, and post-transplantation maintenance in the management of transplantation-eligible newly diagnosed mcl. Final approval of this guidance document was obtained from the Stem Cell Transplant Advisory Committee. Recommendations These recommendations apply to all cases of transplantation-eligible newly diagnosed mcl:■ Alternating cycles of r-chop (rituximab plus cyclophosphamide-doxorubicin-vincristine-prednisolone) and r-dhap [rituximab plus dexamethasone-high-dose cytarabine-cisplatin] is the recommended first-line treatment for symptomatic patients newly diagnosed with mcl before autologous stem-cell transplantation (asct).■ Rituximab plus hyperfractionated cyclophosphamide-vincristine-doxorubicin-dexamethasone (r-hypercvad), alternating with methotrexate and cytarabine, is not recommended for the treatment of patients with newly diagnosed mcl.■ beam (carmustine-etoposide-cytarabine-melphalan), beac (carmustine-etoposide-cytarabine-cyclophosphamide), and total-body irradiation-based regimens are reasonable conditioning options for patients with mcl who have responded to first-line therapy and who are undergoing asct.■ Maintenance therapy with rituximab is recommended for patients with newly diagnosed mcl who have undergone asct.

Abstract
Aim We will review our experience of emergent arterial embolization used to treat haemodynamically unstable patients with obstetric and gynaecological haemorrhage. Methods This is a retrospective study of patients with haemodynamically unstable obstetric and gynaecological haemorrhage treated with emergent arterial embolization from 2010 to 2015. Results 22 patients (average age 41 (SD +/-9) years) had emergent arterial embolization. 63% had post-partum haemorrhage (PPH). 82% of cases were performed with conscious sedation and local anaesthesia. Embolization was technically successful in all cases. Embolization was clinically successful in 95% (21/22). In one case of PPH the patient represented six days later with recurrent bleeding and was treated with surgical suturing of the cervix. There were no complications or deaths. Conclusion Arterial embolization is a highly successful treatment of obstetric and gynaecological haemorrhage in unstable patients.

Abstract
Background Economic evaluations are an integral component of many clinical trials. Costs used in those analyses are based on the prices of branded drugs when they first enter the market. The effect of genericization on the cost-effectiveness (ce) or cost-utility (cu) of an intervention is unknown because economic analyses are rarely updated using the costs of generic drugs. Methods We re-examined the ce or cu of regimens previously evaluated in Canadian Cancer Trials Group (cctg) studies that included prospective economic evaluations and where genericization has occurred or is anticipated in Canada. We incorporated the new costs of generic drugs to characterize changes in ce or cu. We also determined acceptable cost levels of generic drugs that would make regimens reimbursable in a publicly funded health care system. Results The four randomized controlled trials included (representing 1979 patients) were cctg br.10 (early lung cancer, adjuvant vinorelbine-cisplatin vs. observation, n = 172), cctg br.21 (metastatic lung cancer, erlotinib vs. placebo, n = 731), cctg co.17 (metastatic colon cancer, cetuximab vs. best supportive care, n = 557), and cctg ly.12 (relapsed or refractory lymphoma, gemcitabine-dexamethasone-cisplatin vs. cytarabine-dexamethasone-cisplatin, n = 619). Since the initial publication of those trials, the genericization of vinorelbine, erlotinib, cetuximab, and cisplatin has taken place or is expected in Canada. Costs of generics improved the ces and cus of treatment significantly. For example, genericization of erlotinib ($1460.25 per 30 days) resulted in an incremental cost-effectiveness ratio (icer) of $45,746 per life-year gained compared with $94,638 for branded erlotinib. Likewise, genericization of cetuximab ($275.80 per 100 mg) produced an icer of $261,126 per quality-adjusted life-year (qaly) gained compared with $299,613 for branded cetuximab. Decreases in the cost of generic cetuximab to $129.39 and $63.51 would further improve the icer to $150,000 and $100,000 per QALY respectively. Conclusions Genericization of a costly oncology drug can modify the ce and cu of a regimen significantly. Failure to revisit economic analyses with the costs of generics could be a missed opportunity for funding bodies to optimize value-based allocation of health care resources. At current levels, the costs of generics might not be sufficiently low to sustain publicly funded health care systems.

Abstract
BACKGROUND Excess adiposity and adiposity-related inflammation are known risk factors for cardiovascular disease in adults; however, little is known regarding the determinants of adiposity-related inflammation at birth. OBJECTIVES The aim of this study was to investigate the association between maternal pre-pregnancy BMI and newborn adiposity and inflammation. METHODS Paired maternal (28-week gestation) and infant (umbilical cord) blood samples were collected from a population-derived birth cohort (Barwon Infant Study, n = 1074). Data on maternal comorbidities and infant birth anthropomorphic measures were compiled, and infant aortic intima-media thickness was measured by trans-abdominal ultrasound. In a selected subgroup of term infants (n = 161), matched maternal and cord lipids, high-sensitivity C-reactive protein (hsCRP) and maternal soluble CD14 were measured. Analysis was completed by using pairwise correlation and linear regression. Because of their non-normal distribution, pathology blood measures were log transformed prior to analysis. RESULTS Maternal pre-pregnancy BMI was positively associated with increased birth weight (mean difference 17.8 g per kg m-2 , 95% CI 6.6 to 28.9; p = 0.002), newborn mean skin-fold thickness (mean difference 0.1 mm per kg m-2 , 95% CI 0.0 to 0.1; p < 0.001) and cord blood hsCRP (mean difference of 4.2% increase in hsCRP per kg m-2 increase in pre-pregnancy BMI, 95% CI 0.6 to 7.7%, p = 0.02), but not cord blood soluble CD14. Inclusion of maternal hsCRP as a covariate attenuated the associations between pre-pregnancy BMI and both newborn skin-fold thickness and cord blood hsCRP. CONCLUSION Higher maternal pre-pregnancy BMI is associated with increased newborn adiposity and inflammation. These associations may be partially mediated by maternal inflammation during pregnancy.

Population-based cohort study of variation in the use of emergency cholecystectomy for benign gallbladder diseases. Br J Surg 2016; 103:1716-1726. [PMID: 27748962 DOI: 10.1002/bjs.10288] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2016] [Revised: 06/21/2016] [Accepted: 07/06/2016] [Indexed: 01/05/2023]
Abstract
Abstract
Background
The aims of this prospective population-based cohort study were to identify the patient and hospital characteristics associated with emergency cholecystectomy, and the influences of these in determining variations between hospitals.
Methods
Data were collected for consecutive patients undergoing cholecystectomy in acute UK and Irish hospitals between 1 March and 1 May 2014. Potential explanatory variables influencing the performance of emergency cholecystectomy were analysed by means of multilevel, multivariable logistic regression modelling using a two-level hierarchical structure with patients (level 1) nested within hospitals (level 2).
Results
Data were collected on 4744 cholecystectomies from 165 hospitals. Increasing age, lower ASA fitness grade, biliary colic, the need for further imaging (magnetic retrograde cholangiopancreatography), endoscopic interventions (endoscopic retrograde cholangiopancreatography) and admission to a non-biliary centre significantly reduced the likelihood of an emergency cholecystectomy being performed. The multilevel model was used to calculate the probability of receiving an emergency cholecystectomy for a woman aged 40 years or over with an ASA grade of I or II and a BMI of at least 25·0 kg/m2, who presented with acute cholecystitis with an ultrasound scan showing a thick-walled gallbladder and a normal common bile duct. The mean predicted probability of receiving an emergency cholecystectomy was 0·52 (95 per cent c.i. 0·45 to 0·57). The predicted probabilities ranged from 0·02 to 0·95 across the 165 hospitals, demonstrating significant variation between hospitals.
Conclusion
Patients with similar characteristics presenting to different hospitals with acute gallbladder pathology do not receive comparable care.

Rituximab in Lymphoma and Chronic Lymphocytic Leukaemia: A Practice Guideline. Clin Oncol (R Coll Radiol) 2016; 29:e13-e28. [PMID: 27746042 DOI: 10.1016/j.clon.2016.09.004] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2016] [Revised: 06/20/2016] [Accepted: 07/05/2016] [Indexed: 11/25/2022]
Abstract
Rituximab is the first monoclonal antibody to be approved for use by the US Food and Drug Administration in cancer. Its role in the treatment of non-Hodgkin lymphoma, including chronic lymphocytic leukaemia (CLL), has evolved significantly. We aimed to systematically review and update the literature on rituximab in lymphoma and CLL, and provide evidence-based consensus guidelines for its rational use. Validated methodology from the Cancer Care Ontario Program in Evidence-based Care was used. A comprehensive literature search was completed by a methodologist from the Hematology Disease Site Group of Cancer Care Ontario. Data were extracted from randomised controlled trials of rituximab-containing chemotherapy regimens for patients with lymphoma or CLL. Fifty-six primary randomised controlled trials were retrievable and met all inclusion criteria. Clinically important benefits in progression-free survival or overall survival were seen in the following settings: (i) addition of rituximab to combination chemotherapy for initial treatment of aggressive B-cell lymphomas, including diffuse large B-cell lymphoma, Burkitt lymphoma and HIV-related lymphoma with CD4 count ≥50/mm3; (ii) addition of rituximab to combination chemotherapy for initial and subsequent treatment of follicular lymphoma and other indolent B-cell lymphomas; (iii) use of rituximab maintenance in patients with indolent B-cell lymphomas who have responded to chemoimmunotherapy; (iv) addition of rituximab to fludarabine-based chemotherapy or chlorambucil for initial treatment of CLL. The consensus opinion of the Hematology Disease Site Group is that rituximab is recommended for these indications.

Abstract
OBJECTIVE This evidence summary set out to assess the available evidence about the follow-up of asymptomatic survivors of lymphoma who have received curative-intent treatment. METHODS The medline and embase databases and the Cochrane Database of Systematic Reviews were searched for evidence published between 2000 and August 2015 relating to lymphoma survivorship follow-up. The evidence summary was developed by a Working Group at the request of the Cancer Care Ontario Survivorship and Cancer Imaging programs because of the absence of evidence-based practice documents in Ontario for the follow-up and surveillance of asymptomatic patients with lymphoma in complete remission. RESULTS Eleven retrospective studies met the inclusion criteria. The proportion of relapses initially detected by clinical manifestations ranged from 13% to 78%; for relapses initially detected by imaging, the proportion ranged from 8% to 46%. Median time for relapse detection ranged from 8.6 to 19 months for patients initially suspected because of imaging and from 8.6 to 33 months for those initially suspected because of clinical manifestations. Only one study reported significantly earlier relapse detection for patients initially suspected because of clinical manifestations (mean: 4.5 months vs. 6.0 months, p = 0.042). No benefit in terms of overall survival was observed for patients depending on whether their relapse was initially detected because of clinical manifestations or surveillance imaging. SUMMARY Findings in the present study support the importance of improving awareness on the part of survivors and clinicians about the symptoms that might be associated with recurrence. The evidence does not support routine imaging for improving outcomes in this patient population.

Abstract
ABSTRACT
Objective:
National survival rates for out-of-hospital cardiac arrests are less than 5%, and substantial resources are associated with transporting cardiac arrest victims to hospital for emergency department (ED) resuscitation. The low overall survival rate and the identification of predictors of unsuccessful resuscitation have opened debate on the “futility” of transporting such patients to the ED. This study compares the costs of prehospital pronouncement of death to the costs of transporting patients to a hospital ED for physician pronouncement.
Methods:
The study was a retrospective chart review on a matched cohort of out-of-hospital cardiac arrest patients. Patients were included if documentation was adequate and ambulance response time was less than 8 minutes. A cohort of 20 patients pronounced dead in the field were matched to 20 patients pronounced dead in an ED. Cases were matched on 6 evidence-based predictors of unsuccessful resuscitation. Direct medical costs and mean physician and prehospital provider times were compared.
Results:
The total cost of pronouncement of death in the ED was $45.35 higher than the cost of field pronouncement (p < 0.001). Paramedics spent more time delivering care when death was pronounced in the field (83.3 vs. 55.9 min; p < 0.001). Base hospital physicians spent more time when patients were transported to hospital for ED pronouncement (16.3 vs. 4.3 min; p < 0.001). Total provider time for field pronouncement was 15.5 min longer (p = 0.004), but field pronouncement consumed 12.0 min less physician time.
Conclusions:
Paramedic pronouncement of death in the field is less costly than transporting patients to hospital for physician pronouncement. Pronouncement in the field requires more paramedic time but less physician time.

Utility of faecal calprotectin in inflammatory bowel disease (IBD): what cut-offs should we apply? Frontline Gastroenterol 2015; 6:14-19.

Abstract
BACKGROUND Faecal calprotectin (FC), a cytosolic protein released by neutrophils (S100 family) in response to inflammation, is a simple, non-invasive test that can be used to differentiate irritable bowel syndrome (IBS) with inflammatory bowel disease (IBD), where there can be considerable symptom overlap. AIMS AND METHODS The aims of the study were (1) to be able to predict the ability of FC to exclude IBD and determine cut-offs when in remission, (2) to investigate the effects of time and temperature on stability of FC and (3) compare three ELISA kits to measure FC: Buhlmann, PhiCal v1 and PhiCal v2. A total of 311 patients with altered bowel habit were tested for FC; 144 with IBS, 148 with IBD and 19 with other organic causes. RESULTS Sensitivity and specificity of FC (with PhiCal v2 kit) to distinguish between functional disorder (IBS) and IBD using cut-off 50 μg/g were 88% and 78%, respectively, with a negative predictive value of 87%. Area under the receiver operating curve was 0.84 (CI 0.78 to 0.90). For those with IBD, FC values below 250 μg/g corresponded with remission of disease with a sensitivity and specificity of 90% and 76%, respectively. Area under the receiver operating curve was 0.93 (CI 0.89 to 0.97). FC was stable once extracted and frozen for up to 2.5 months. Pearson correlation was good between Buhlmann assay and PhiCal v2 (r2 = 0.95). CONCLUSIONS FC has up to 87% negative predictive value to exclude IBD, and cut-offs less than 250 μg/g had 90% sensitivity to determine remission in IBD. Once frozen, FC is stable and the ELISA monoclonal plates were broadly comparable.

Abstract
BACKGROUND In immunocompetent patients with primary central nervous system lymphoma (PCNSL), combined modality therapy (CMT) using high-dose methotrexate and radiotherapy (WBRT) has improved response rates compared with chemotherapy alone. The trade-off is delayed and potentially devastating treatment-related neurotoxicity (NT). METHODS A cost-effectiveness analysis using a Markov model compared CMT with chemotherapy alone in age-stratified patients with PCNSL. Baseline probabilities were derived from a systematic literature review. Direct and lost productivity costs were collected from a Canadian perspective and presented in Can$ in 2011. Outcomes were life expectancy, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratio. RESULTS The quality-adjusted life expectancy was 1.55 QALYs for CMT and 1.53 QALYs for chemotherapy alone. In younger patients (aged <60 years), CMT yielded 2.44 QALYs, compared with 1.89 QALYs for chemotherapy alone, yielding an expected benefit with CMT of 0.55 QALYs or 6.6 quality-adjusted months. The CMT strategy dominated in younger patients, as it was Can$11 951 less expensive than chemotherapy alone. The chemotherapy-alone strategy dominated in older patients, as it was Can$11 244 less expensive than CMT, and there was no difference in QALYs between the strategies. The model was robust in sensitivity analyses of key variables tested through the plausible ranges obtained from costing sources and published literature. CONCLUSION The preferred induction strategy for younger patients with PCNSL appears to be CMT, which minimized cost while maximizing life expectancy and QALYs. This analysis confirms that the preferred strategy for older patients is chemotherapy alone.

Abstract
UNLABELLED Obturator hernia is a rare condition occurring predominantly in elderly, thin, female patients and causes significant morbidity and mortality. Due to obscure presenting symptoms and signs, diagnosis and management are often delayed. While previous studies have attributed the high mortality to the delay in diagnosis, current literature remains controversial about this issue. The aim of this study was to identify peri-operative risk factors associated with mortality in patients with obturator hernia at our hospital. METHODS We retrospectively reviewed our series of 20 consecutive patients who underwent surgical repair of 21 obturator herniae and examined their clinical characteristics and post-operative outcomes. RESULTS Overall mortality rate was 47.6 %. Survivors did not differ from non-survivors in terms of basic demographics and operative parameters (operative time, blood loss and the need for intestinal resection). The use of computed tomography for pre-operative diagnosis was associated with reduced need for bowel resection, but did not result in shorter time to operation or improved morbidity and mortality. Our series demonstrated that early timing of surgery alone did not improve operative outcome. The absence of bowel motion and a high serum urea level at the time of operation were independent factors for mortality. CONCLUSIONS Obturator hernia remains a highly lethal surgical emergency. Adequate peri-operative resuscitation may be the key to further improvement in surgical outcomes.

Abstract
BACKGROUND Promising new drugs such as lenalidomide, an immunomodulatory agent, are available for the treatment of multiple myeloma. We describe the process of creating a provincial guideline for the use of lenalidomide, alone or in combination with other drugs, in relapsed, refractory, or newly diagnosed disease (including smoldering and symptomatic patients, and candidates and non-candidates for transplant) and in maintenance treatment (after transplant or non-transplant therapy); and for strategies to manage lenalidomide-related toxicities. METHODS Outcomes of interest included overall survival, event-free survival, progression-free survival, time to progression, time to next treatment, response rate, and incidence of serious toxicity. The medline, embase, and Cochrane Library databases, as well as meeting abstracts and the Web sites of relevant organizations, were systematically searched for relevant literature. RESULTS Recommendations were developed using the evidence from published studies and the clinical expertise of the working group and of the Cancer Care Ontario Hematology Disease Site Group. CONCLUSIONS Lenalidomide in combination with dexamethasone can be recommended for both previously untreated and treated patients with multiple myeloma. Guidelines for the management of cytopenias, venous thromboembolism, and second primary malignancies are discussed.
