Management of solid tumours in organ-transplant recipients

Malignancy is a well-recognised complication of transplantation and can occur de novo, as a recurrence of a pre-existing malignancy, or from transmission of malignancy from the donor. Common de-novo malignancies are those of the skin and the lymphoreticular system. Various solid-organ cancers have also been reported in transplant recipients and each poses a unique management challenge in view of the unusual setting. We review solid-organ cancers in transplant recipients and their management, including surveillance and prevention.

Clinical trial designs for rare diseases: Studies developed and discussed by the International Rare Cancers Initiative

Background The past three decades have seen rapid improvements in the diagnosis and treatment of most cancers and the most important contributor has been research. Progress in rare cancers has been slower, not least because of the challenges of undertaking research. Settings The International Rare Cancers Initiative (IRCI) is a partnership which aims to stimulate and facilitate the development of international clinical trials for patients with rare cancers. It is focused on interventional – usually randomised – clinical trials with the clear goal of improving outcomes for patients. The key challenges are organisational and methodological. A multi-disciplinary workshop to review the methods used in ICRI portfolio trials was held in Amsterdam in September 2013. Other as-yet unrealised methods were also discussed. Results The IRCI trials are each presented to exemplify possible approaches to designing credible trials in rare cancers. Researchers may consider these for use in future trials and understand the choices made for each design. Interpretation Trials can be designed using a wide array of possibilities. There is no ‘one size fits all’ solution. In order to make progress in the rare diseases, decisions to change practice will have to be based on less direct evidence from clinical trials than in more common diseases.

Evaluation of glomerular filtration rate estimation by Cockcroft–Gault, Jelliffe, Wright and Modification of Diet in Renal Disease (MDRD) formulae in oncology patients

BACKGROUND The aim was to evaluate the accuracy of Cockcroft-Gault, Jelliffe, Wright and Modification of Diet in Renal Disease (MDRD) formulae as a substitute for the gold standard measure of glomerular filtration rate (GFR) using chromium 51 EDTA. PATIENTS AND METHODS Retrospective analysis of GFR measurements in oncology patients from a University Teaching Hospital over 3 years was carried out. Bias and precision of estimates of GFR were compared with measured GFR. RESULTS Six hundred and sixty patients with measured GFR (median 90 ml/min, range 23-179 ml/min) were identified. Cockcroft-Gault produced the smallest bias (median percentage error -1.4%) and highest precision (median absolute percentage error 14.0%) and was the most accurate for carboplatin dosing. For patients>30% over their ideal body weight (IBW), using IBW+30% in the Cockcroft-Gault formula was more precise than using actual body weight or IBW. The Wright formula was most accurate for patients aged 70+years and patients with a body mass index (BMI)≥30 but overestimated GFR when GFR<50 ml/min. CONCLUSIONS When measured GFR is unavailable, we advise estimating GFR using the Cockcroft-Gault formula and using IBW+30% for patients weighing>30% over their IBW. If the GFR is ≥50 ml/min and the patient is >70 years and/or BMI≥30, the Wright formula gives the best estimate of GFR.

Teenage and Young Adult Cancer-Related Fatigue Is Prevalent, Distressing, and Neglected: It Is Time to Intervene. A Systematic Literature Review and Narrative Synthesis

PURPOSE Cancer-related fatigue in adults has been the subject of considerable recent research, confirming its importance as a common and debilitating symptom, and establishing a number of evidence-based interventions. There has, however, been limited focus on the fatigue suffered by teenagers and young adults with cancer, a group recognized as having unique experiences and developmental needs. We have undertaken a systematic review of the literature to provide a comprehensive overview of studies evaluating fatigue in this younger patient group in order to guide clinical practice and future research. METHOD We searched MEDLINE, EMBASE, PsycINFO, and CINAHL databases for literature containing data relating to any aspect of fatigue in patients aged 13-24 at cancer diagnosis or treatment. RESULTS Sixty articles were identified, of which five described interventional clinical trials. Cancer-related fatigue was consistently one of the most prevalent, severe, and distressing symptoms, and it persisted long-term in survivors. It was associated with a number of factors, including poor sleep, depression, and chemotherapy. There was little evidence for the effectiveness of any intervention, although exercise appears to be the most promising. Importantly, fatigue was itself a significant barrier to physical and social activities. CONCLUSION Cancer-related fatigue is a major and disabling problem in young cancer patients. Effective management strategies are needed to avoid compounding the dependence and social isolation of this vulnerable patient group. Future research should focus on providing evidence for the effectiveness of interventions, of which activity promotion and management of concurrent symptoms are the most promising.

Management of malignant ovarian germ cell tumors.

Malignant ovarian germ cell tumors are rare, highly curable cancers of young women. The majority of patients can be cured with either fertility-preserving surgery alone or a combination of surgery and chemotherapy. Relapses occur in 10% to 20% of patients, and the significant proportion of them can be salvaged with chemotherapy. There is no evidence that treatment for malignant ovarian germ cell tumors will adversely affect menstrual or reproductive functions, increase future pregnancy loss, or increase the risk of congenital malformations of the fetus. Late effects, such as secondary leukemia, from chemotherapy are reported but rare. Target Audience: Obstetricians & Gynecologists and Family Physicians. Learning Objective: After completing this CME activity, physicians should be better able to diagnose ovarian germ cell tumors, outline management of malignant ovarian germ cell tumors, and understand the impact of treatment on fertility and late effects.

Non‐pineal supratentorial primitive neuro‐ectodermal tumors (sPNET) in teenagers and young adults: Time to reconsider cisplatin based chemotherapy after cranio‐spinal irradiation?

Supratentorial PNET (sPNET) are rare CNS tumors of embryonal origin arising in children and adults. The treatment of sPNET for all age groups at our cancer center has been based on the management of medulloblastoma (MB), involving neurosurgical debulking followed by cranio‐spinal irradiation (CSI) and systemic chemotherapy.

Trabectedin for advanced soft tissue sarcomas: a single institution experience

BACKGROUND We retrospectively analyzed data from patients who had been treated with trabectedin at our institution between April 2009 and August 2011. PATIENTS & METHODS Data from 25 patients with recurrent soft tissue sarcoma (leiomyosarcoma: n = 8; liposarcoma: n = 5) were used to assess the efficacy and safety of trabectedin 1.5 mg/m(2) given every 3 weeks. RESULTS Most patients (n = 14) had been heavily pretreated with ≥ 2 previous chemotherapy lines. Eight (32%) patients achieved a partial response according to dimensional and tumor density changes, and seven (28%) patients had stable disease for ≥ 3 months (clinical benefit rate = 60%; n = 15). Median progression-free survival was 6.4 months and overall survival 19.3 months. Common adverse events were fatigue, nausea, anemia and transient transaminase increases. CONCLUSION Treatment with trabectedin is effective and well tolerated in heavily pretreated soft tissue sarcoma patients. Tapering dexamethasone courses and switching trabectedin administration to an every 4 weeks schedule effectively dealt with persistent fatigue without compromising effectiveness.

Multidisciplinary management of malignant ovarian germ cell tumours

OBJECTIVES Malignant ovarian germ cell tumours (MOGCT) are rare cancers of young women. Limited prospective trials exist from which evidence-based management can be developed. This review summarizes the available literature concerning MOGT in order to provide the clinician with information relevant to their multidisciplinary management. METHODS MEDLINE was searched between 1966 and 2010 for all publications in English where the studied population included women diagnosed with malignant ovarian germ cell tumours. RESULTS The majority of patients can be cured with fertility-preserving surgery with or without combination chemotherapy. Long term survival approaches 100% in early stage disease and is approximately 75% in advanced stage disease. Most studies suggest that the treatment has little, if any, effect on future fertility and limited data suggest that there is no adverse effect on the future quality of life. CONCLUSION MOGCTs are rare tumours of young women the majority of which can be successfully treated with fertility-preserving surgery with or without chemotherapy with preservation of reproductive function. Minimisation of chemotherapy in good prognostic groups and improved treatment in resistant and relapsed MOGCT are important goals for the future. Further studies are needed to quantify the late adverse effects of treatment in long term survivors.

Anticancer chemotherapy in teenagers and young adults: managing long term side effects

#### What you need to know Cancer is the leading cause of disease related death in teenagers and young adults (TYAs) in Western countries.1 2 In the UK, cancer in TYAs accounts for 9% and 15% of all male and female deaths respectively, and its incidence has risen by 19% since the mid-1990s, leading to 2300 new cases a year between 2011 and 2013.1 In Japan it accounted for nearly 7000 deaths between 2000 and 2006.3 TYA cancer survivors are likely to live for many decades but are at risk of late effects of their treatment. This article provides information for generalists on late effects of anticancer chemotherapy (see infographic and supplementary table A) that may affect quality of life. Radiotherapy related effects are not discussed but are summarised elsewhere.4 There is no internationally accepted age definition for TYAs. In the UK, TYA age is 15-24 years, whereas the US National Cancer Institute defines adolescents and young adults as aged 15-39 years. In this review we use the UK definition of 15-24 years. #### Sources and selection criteria This article is an evidence based review of late effects of chemotherapy in teenagers and young adults (TYAs). Our review encompasses studies using all age ranges termed as TYA or adolescents and young adult (AYA). We searched PubMed and the Cochrane databases between 1990 and 2016 using the search terms “teenage and young …

Epirubicin, Cisplatin, and Capecitabine for Primary Platinum-Resistant or Platinum-Refractory Epithelial Ovarian Cancer: Results of a Retrospective, Single-Institution Study

Objective Primary platinum-resistant epithelial ovarian cancer (EOC) is an area of unmet medical need. There is limited evidence from small studies that platinum-based combinations can overcome “resistance” in a proportion of patients. We investigated the efficacy and toxicity of platinum-based combination chemotherapy in the platinum-resistant and platinum-refractory setting. Methods Epirubicin, cisplatin, and capecitabine (ECX) combination chemotherapy was used at our institution for the treatment of relapsed EOC. From the institutional database, we identified all patients with primary platinum-refractory or platinum-resistant relapse treated with ECX as second-line therapy between 2001 and 2012. We extracted demographic, clinical, treatment, and toxicity data and outcomes. We used logistic and Cox regression models to identify predictors of response and survival respectively. Results Thirty-four 34 patients (8 refractory, 26 resistant) were treated with ECX. Response Evaluation Criteria In Solid Tumors (RECIST) response rate was 45%, median progression-free survival (PFS) was 6.4 months, and overall survival (OS) was 10.6 months. Platinum-resistant patients had better outcomes than did platinum-refractory patients (response rate, 54% vs 0%, P = 0.047; PFS 7.2 vs 1.8 months, P < 0.0001; OS 14.4 vs 3 months, P < 0.001). In regression models, time to progression after first-line treatment and platinum-refractory status were the strongest predictors of response and PFS or OS, respectively. Patients with time to progression after first-line treatment longer than 3 months showed PFS and OS of 7.9 and 14.7 months, respectively. Toxicity was manageable, with only 13% of cycles administered at reduced doses. Conclusions Epirubicin, cisplatin, and capecitabine seems to be active in platinum-resistant relapsed EOC with manageable toxicity. Further prospective investigation of platinum-anthracycline combinations is warranted in patients who relapse 3 to 6 months after first-line platinum-taxane treatment.
