RESUMEN

PURPOSE: Survival in stage I seminoma is almost 100%. Computed tomography (CT) surveillance is an international standard of care, avoiding adjuvant therapy. In this young population, minimizing irradiation is vital. The Trial of Imaging and Surveillance in Seminoma Testis (TRISST) assessed whether magnetic resonance images (MRIs) or a reduced scan schedule could be used without an unacceptable increase in advanced relapses. METHODS: A phase III, noninferiority, factorial trial. Eligible participants had undergone orchiectomy for stage I seminoma with no adjuvant therapy planned. Random assignment was to seven CTs (6, 12, 18, 24, 36, 48, and 60 months); seven MRIs (same schedule); three CTs (6, 18, and 36 months); or three MRIs. The primary outcome was 6-year incidence of Royal Marsden Hospital stage ≥ IIC relapse (> 5 cm), aiming to exclude increases ≥ 5.7% (from 5.7% to 11.4%) with MRI (v CT) or three scans (v 7); target N = 660, all contributing to both comparisons. Secondary outcomes include relapse ≥ 3 cm, disease-free survival, and overall survival. Intention-to-treat and per-protocol analyses were performed. RESULTS: Six hundred sixty-nine patients enrolled (35 UK centers, 2008-2014); mean tumor size was 2.9 cm, and 358 (54%) were low risk (< 4 cm, no rete testis invasion). With a median follow-up of 72 months, 82 (12%) relapsed. Stage ≥ IIC relapse was rare (10 events). Although statistically noninferior, more events occurred with three scans (nine, 2.8%) versus seven scans (one, 0.3%): 2.5% absolute increase, 90% CI (1.0 to 4.1). Only 4/9 could have potentially been detected earlier with seven scans. Noninferiority of MRI versus CT was also shown; fewer events occurred with MRI (two [0.6%] v eight [2.6%]), 1.9% decrease (-3.5 to -0.3). Per-protocol analyses confirmed noninferiority. Five-year survival was 99%, with no tumor-related deaths. CONCLUSION: Surveillance is a safe management approach-advanced relapse is rare, salvage treatment successful, and outcomes excellent, regardless of imaging frequency or modality. MRI can be recommended to reduce irradiation; and no adverse impact on long-term outcomes was seen with a reduced schedule.

RESUMEN

OBJECTIVE: Replying to germ cell tumour patients' needs, we implemented "Shared Community Follow-up"-a collaborative initiative, enabling remote delivery of specialist cancer care across large geographical areas. Blood, radiological investigations and patient-reported outcome measures (PROMs) are completed remotely and integrated within the electronic patient records for specialist review without patients requiring appointments. We describe the service evaluation estimating the feasibility, safety and acceptability of this initiative versus traditional Standard Follow-up. METHODS: This cross-sectional evaluation estimated feasibility (uptake, adherence) and safety (via missed appointments, timeliness, cancellations) using routinely collected service process data. An acceptability questionnaire, evaluating patient satisfaction, was administered to 91 patients. RESULTS: The new service is feasible. Across 2 years (2014-2016), uptake increased 54% (N = 123 to N = 270) and only 4.8% (N = 13) of patients were non-adherent. Fewer missed/cancelled investigations (N = 39, 5.9% vs. N = 566, 85.5%), timelier investigations (seven vs. 14 timely investigations) and equal relapse detection suggest its safety. PROMs replaced 3 appointments/patient. Patients were as satisfied with both services (3.4/4 vs. 3.6/4). CONCLUSION: New follow-up services, with investigations completed remotely and shared between community providers and cancer centres, offer an alternative to traditional appointments with advantages for patients and the National Health Service.

RESUMEN

BACKGROUND: Capivasertib (AZD5363) is a potent selective oral inhibitor of all three isoforms of the serine/threonine kinase AKT. The FAKTION trial investigated whether the addition of capivasertib to fulvestrant improved progression-free survival in patients with aromatase inhibitor-resistant advanced breast cancer. METHODS: In this randomised, double-blind, placebo-controlled, phase 2 trial, postmenopausal women aged at least 18 years with an Eastern Cooperative Oncology Group performance status of 0-2 and oestrogen receptor-positive, HER2-negative, metastatic or locally advanced inoperable breast cancer who had relapsed or progressed on an aromatase inhibitor were recruited from 19 hospitals in the UK. Enrolled participants were randomly assigned (1:1) to receive intramuscular fulvestrant 500 mg (day 1) every 28 days (plus a loading dose on day 15 of cycle 1) with either capivasertib 400 mg or matching placebo, orally twice daily on an intermittent weekly schedule of 4 days on and 3 days off (starting on cycle 1 day 15) until disease progression, unacceptable toxicity, loss to follow-up, or withdrawal of consent. Treatment allocation was done using an interactive web-response system using a minimisation method (with a 20% random element) and the following minimisation factors: measurable or non-measurable disease, primary or secondary aromatase inhibitor resistance, PIK3CA status, and PTEN status. The primary endpoint was progression-free survival with a one-sided alpha of 0·20. Analyses were done by intention to treat. Recruitment is complete, and the trial is in follow-up. This trial is registered with ClinicalTrials.gov, number NCT01992952. FINDINGS: Between March 16, 2015, and March 6, 2018, 183 patients were screened for eligibility, of whom 140 (76%) were eligible and were randomly assigned to receive fulvestrant plus capivasertib (n=69) or fulvestrant plus placebo (n=71). Median follow-up for progression-free survival was 4·9 months (IQR 1·6-11·6). At the time of primary analysis for progression-free survival (Jan 30, 2019), 112 progression-free survival events had occurred, 49 (71%) in 69 patients in the capivasertib group compared with 63 (89%) of 71 in the placebo group. Median progression-free survival was 10·3 months (95% CI 5·0-13·2) in the capivasertib group versus 4·8 months (3·1-7·7) in the placebo group, giving an unadjusted hazard ratio (HR) of 0·58 (95% CI 0·39-0·84) in favour of the capivasertib group (two-sided p=0·0044; one-sided log rank test p=0·0018). The most common grade 3-4 adverse events were hypertension (22 [32%] of 69 patients in the capivasertib group vs 17 [24%] of 71 in the placebo group), diarrhoea (ten [14%] vs three [4%]), rash (14 [20%] vs 0), infection (four [6%] vs two [3%]), and fatigue (one [1%] vs three [4%]). Serious adverse reactions occurred only in the capivasertib group, and were acute kidney injury (two), diarrhoea (three), rash (two), hyperglycaemia (one), loss of consciousness (one), sepsis (one), and vomiting (one). One death, due to atypical pulmonary infection, was assessed as possibly related to capivasertib treatment. One further death in the capivasertib group had an unknown cause; all remaining deaths in both groups (19 in the capivasertib group and 31 in the placebo group) were disease related. INTERPRETATION: Progression-free survival was significantly longer in participants who received capivasertib than in those who received placebo. The combination of capivasertib and fulvestrant warrants further investigation in phase 3 trials. FUNDING: AstraZeneca and Cancer Research UK.

RESUMEN

BACKGROUND: Standard management in the UK for high-risk stage 1 nonseminoma germ cell tumours of the testis (NSGCTT) is two cycles of adjuvant bleomycin, etoposide (360 mg/m2), and cisplatin (BE360P) chemotherapy, or surveillance. OBJECTIVE: To test whether one cycle of BE500P achieves similar recurrence rates to two cycles of BE360P. DESIGN, SETTING, AND PARTICIPANTS: A total of 246 patients with vascular invasion-positive stage 1 NSGCTT or combined seminoma + NSGCTT were centrally registered in a single-arm prospective study. INTERVENTION: One cycle comprising bleomycin 30000 IU on days 1, 8, and 15, etoposide 165 mg/m2 on days 1-3, and cisplatin 50 mg/m2 on days 1-2, plus antibacterial and granulocyte colony stimulating factor prophylaxis. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was 2-yr malignant recurrence (MR); the aim was to exclude a rate of ≥5%. Participants had regular imaging and tumour marker (TM) assessment for 5 yr. RESULTS AND LIMITATIONS: The median follow-up was 49 mo (interquartile range 37-60). Ten patients with rising TMs at baseline were excluded. Four patients had MR at 6, 7, 13, and 27 mo; all received second-line chemotherapy and surgery and three remained recurrence-free at 5 yr. The 2-yr MR rate was 1.3% (95% confidence interval 0.3-3.7%). Three patients developed nonmalignant recurrences with localised teratoma differentiated, rendered disease-free after surgery. Grade 3-4 febrile neutropenia occurred in 6.8% of participants. CONCLUSIONS: BE500P is safe and the 2-yr MR rate is consistent with that seen following two BE360P cycles. The 111 study is the largest prospective trial investigating one cycle of adjuvant BE500P in high-risk stage 1 NSGCTT. Adoption of one cycle of BE500P as standard would reduce overall exposure to chemotherapy in this young population. PATIENT SUMMARY: Removing the testicle fails to cure many patients with high-risk primary testicular cancer since undetectable cancers are often present elsewhere. A standard additional treatment in Europe is two cycles of chemotherapy to eradicate these. This trial shows one cycle has few adverse effects and comparable outcomes to those seen with two cycles.

RESUMEN

BACKGROUND: Monitoring and managing data returns in multi-centre randomised controlled trials is an important aspect of trial management. Maintaining consistently high data return rates has various benefits for trials, including enhancing oversight, improving reliability of central monitoring techniques and helping prepare for database lock and trial analyses. Despite this, there is little evidence to support best practice, and current standard methods may not be optimal. METHODS: We report novel methods from the Trial of Imaging and Schedule in Seminoma Testis (TRISST), a UK-based, multi-centre, phase III trial using paper Case Report Forms to collect data over a 6-year follow-up period for 669 patients. Using an automated database report which summarises the data return rate overall and per centre, we developed a Microsoft Excel-based tool to allow observation of per-centre trends in data return rate over time. The tool allowed us to distinguish between forms that can and cannot be completed retrospectively, to inform understanding of issues at individual centres. We reviewed these statistics at regular trials unit team meetings. We notified centres whose data return rate appeared to be falling, even if they had not yet crossed the pre-defined acceptability threshold of an 80% data return rate. We developed a set method for agreeing targets for gradual improvement with centres having persistent data return problems. We formalised a detailed escalation policy to manage centres who failed to meet agreed targets. We conducted a post-hoc, descriptive analysis of the effectiveness of the new processes. RESULTS: The new processes were used from April 2015 to September 2016. By May 2016, data return rates were higher than they had been at any time previously, and there were no centres with return rates below 80%, which had never been the case before. In total, 10 centres out of 35 were contacted regarding falling data return rates. Six out of these 10 showed improved rates within 6-8 weeks, and the remainder within 4 months. CONCLUSIONS: Our results constitute preliminary effectiveness evidence for novel methods in monitoring and managing data return rates in randomised controlled trials. We encourage other researchers to work on generating better evidence-based methods in this area, whether through more robust evaluation of our methods or of others.

RESUMEN

Bleomycin, a cytotoxic chemotherapy agent, forms a key component of curative regimens for lymphoma and germ cell tumours. It can be associated with severe toxicity, long-term complications and even death in extreme cases. There is a lack of evidence or consensus on how to prevent and monitor bleomycin toxicity. We surveyed 63 germ cell cancer physicians from 32 cancer centres across the UK to understand their approach to using bleomycin. Subsequent guideline development was based upon current practice, best available published evidence and expert consensus. We observed heterogeneity in practice in the following areas: monitoring; route of administration; contraindications to use; baseline and follow-up investigations performed, and advice given to patients. A best-practice clinical guideline for the use of bleomycin in the treatment of germ cell tumours has been developed and includes recommendations regarding baseline investigations, the use of pulmonary function tests, route of administration, monitoring and patient advice. It is likely that existing heterogeneity in clinical practice of bleomycin prescribing has significant economic, safety and patient experience implications. The development of an evidence-based consensus guideline was supported by 93% of survey participants and aims to address these issues and homogenise practice across the UK.

RESUMEN

Context: Denosumab, an inhibitor of receptor activator of nuclear factor κ-B ligand, is an approved treatment of giant cell tumor of bone (GCTB) in adults and "skeletally mature" adolescents. Safety concerns include oversuppression of bone remodelling, with risk of osteonecrosis of the jaw (ONJ) and atypical femur fractures during treatment in adults and rebound hypercalcemia after treatment cessation in children. To date, ONJ has never been reported in children or adolescents. Objectives: To describe serious adverse effects during and following high-dose denosumab therapy in GCTB patients. Patients: Two adolescents (14 and 15 years) and a young adult (40 years) received fixed-dose denosumab for GCTB for 1.3 to 4 years (cumulative dose, 47 to 98 mg/kg), which was stopped because of development of ONJ in one adolescent and bilateral femoral cortical stress reactions in the young adult. All three patients developed rebound hypercalcemia with acute kidney injury 5.5 to 7 months after denosumab cessation. Results: The ONJ necessitated surgical debridement. Rebound hypercalcemia (serum calcium, 3.1 to 4.3 mmol/L) was unresponsive to hyperhydration alone, requiring repeated doses of calcitonin or intravenous bisphosphonate treatment. Hypercalcemia recurred in two patients within 4 weeks, with normal serum calcium profiles thereafter. All patients were naive to chemotherapy, radiotherapy, bisphosphonates, and corticosteroids and were metastases free, confirming the causative role of denosumab in these complications. Conclusion: These suppression-release effects of high-dose denosumab on bone remodeling raise questions about safety of fixed dosing and treatment duration. In young people, weight-adjusted dosing and safety monitoring during and after antiresorptive therapy is required.

RESUMEN

BACKGROUND: Cisplatin is one of the most ototoxic chemotherapy drugs, resulting in a permanent and irreversible hearing loss in up to 50% of patients. Cisplatin and gentamicin are thought to damage hearing through a common mechanism, involving reactive oxygen species in the inner ear. Aspirin has been shown to minimise gentamicin-induced ototoxicity. We, therefore, tested the hypothesis that aspirin could also reduce ototoxicity from cisplatin-based chemotherapy. METHODS: A total of 94 patients receiving cisplatin-based chemotherapy for multiple cancer types were recruited into a phase II, double-blind, placebo-controlled trial and randomised in a ratio of 1:1 to receive aspirin 975 mg tid and omeprazole 20 mg od, or matched placebos from the day before, to 2 days after, their cisplatin dose(s), for each treatment cycle. Patients underwent pure tone audiometry before and at 7 and 90 days after their final cisplatin dose. The primary end-point was combined hearing loss (cHL), the summed hearing loss at 6 kHz and 8 kHz, in both ears. RESULTS: Although aspirin was well tolerated, it did not protect hearing in patients receiving cisplatin (p-value = 0.233, 20% one-sided level of significance). In the aspirin arm, patients demonstrated mean cHL of 49 dB (standard deviation [SD] 61.41) following cisplatin compared with placebo patients who demonstrated mean cHL of 36 dB (SD 50.85). Women had greater average hearing loss than men, and patients treated for head and neck malignancy experienced the greatest cHL. CONCLUSIONS: Aspirin did not protect from cisplatin-related ototoxicity. Cisplatin and gentamicin may therefore have distinct ototoxic mechanisms, or cisplatin-induced ototoxicity may be refractory to the aspirin regimen used here.

RESUMEN

Germ cell tumors (GCTs) are rare but clinically and pathologically diverse tumors that occur in an extensive range of age groups, from children to older adults and which include both seminomatous and nonseminomatous tumors. Current clinical management for both male and female teenagers and young adults (TYAs) with GCTs remains inconsistent, alternating between pediatric and adult multidisciplinary oncology teams, based on locally defined age cutoffs. Therefore, we reviewed available literature to determine the biological similarities and differences between GCTs in young children (0-12 years), TYAs (13-24 years), and older adults (>24 years). GCTs arising in pediatric and adult populations in general showed marked molecular biological differences within identical histological subtypes, whereas there was a distinct paucity of available data for GCTs in the TYA population. These findings highlight that clinical management based simply on chronological age may be inappropriate for TYA and suggests that the optimal future management of GCTs should consider specific molecular biological factors in addition to clinical parameters in the context of patient-specific age group rather than medical specialty.

RESUMEN

The impact of cancer on healthcare is increasing. Therefore, it is key that all doctors receive oncology training. This study surveyed UK undergraduate medical schools to determine the extent of oncology training provided by their curricula. Data on foundation year (FY) and core medical training (CMT) programmes were obtained and analysed for the proportion of oncology posts. Of the responding medical schools, five (36%) had a defined period dedicated to oncology (mean 2 weeks). Four foundation schools were in London, with 10,094 FY posts in 1699 programmes. Of these, 1.5% of post and 8.7% of programmes were in oncology. For CMT offered by the London deanery specialty schools, 11% of CMT post and 48% of programmes included oncology. Oncology was included in 11% posts and 48% programmes offered by the London Deanery specialty schools. Our results show that < 50% of junior doctors receive dedicated undergraduate or postgraduate oncology training. An increase in oncology training is therefore urgently required.

RESUMEN

BACKGROUND: Tivantinib is a selective, small-molecule inhibitor of the MET receptor tyrosine kinase. Preclinical and phase 1 data suggested a possible role for MET in the pathophysiology of germ cell tumors (GCTs) and a potential clinical benefit from tivantinib in patients with these tumors. METHODS: Men (≥ 16 years) with relapsed or refractory, histologically confirmed, non-central nervous system GCTs received oral tivantinib 360 mg twice daily in 28-day cycles until progressive disease or unacceptable toxicity. The primary endpoint was objective response rate in the first 4 cycles, with study termination for <2 responses among the first 21 patients. Secondary endpoints included 12-week progression-free survival (PFS), overall survival (OS), and safety. RESULTS: Twenty-seven patients were enrolled in 9 months (median age, 32 years). Most patients had tumors with nonseminoma histology (n = 25), and primary tumor sites were testis (n = 24) and mediastinum (n = 3). Among 25 evaluable patients, no objective responses were observed; accrual was halted when the 21st patient became evaluable. Best response was stable disease (n = 5). Median PFS was 1 month, the 12-week PFS rate was 21 %, and median OS was 6 months. Grade 3 or 4 adverse events considered related to study drug included grade 3 pneumonia and grade 3 syncope (n = 1, each). CONCLUSIONS: Tivantinib was well tolerated but did not demonstrate single-agent activity in patients with relapsed/refractory GCTs. Rapid accrual to this phase 2 trial was achieved in this rare patient population through multicenter collaboration.

RESUMEN

PURPOSE: Initial results of a randomized trial comparing carboplatin with radiotherapy (RT) as adjuvant treatment for stage I seminoma found carboplatin had a noninferior relapse-free rate (RFR) and had reduced contralateral germ cell tumors (GCTs) in the short-term. Updated results with a median follow-up of 6.5 years are now reported. PATIENTS AND METHODS: Random assignment was between RT and one infusion of carboplatin dosed at 7 × (glomerular filtration rate + 25) on the basis of EDTA (n = 357) and 90% of this dose if determined on the basis of creatinine clearance (n = 202). The trial was powered to exclude a doubling in RFRs assuming a 96-97% 2-year RFR after radiotherapy (hazard ratio [HR], approximately 2.0). RESULTS: Overall, 1,447 patients were randomly assigned in a 3-to-5 ratio (carboplatin, n = 573; RT, n = 904). RFRs at 5 years were 94.7% for carboplatin and 96.0% for RT (RT-C 90% CI, 0.7% to 3.5%; HR, 1.25; 90% CI, 0.83 to 1.89). One death as a result of seminoma (in RT arm) occurred. Patients receiving at least 99% of the 7 × AUC dose had a 5-year RFR of 96.1% (95% CI, 93.4% to 97.7%) compared with 92.6% (95% CI, 88.0% to 95.5%) in those who received lower doses (HR, 0.51; 95% CI, 0.24 to 1.07; P = .08). There was a clear reduction in the rate of contralateral GCTs (carboplatin, n = 2; RT, n = 15; HR, 0.22; 95% CI, 0.05 to 0.95; P = .03), and elevated pretreatment follicle-stimulating hormone (FSH) levels (> 12 IU/L) was a strong predictor (HR, 8.57; 95% CI, 1.82 to 40.38). CONCLUSION: These updated results confirm the noninferiority of single dose carboplatin (at 7 × AUC dose) versus RT in terms of RFR and establish a statistically significant reduction in the medium term of risk of second GCT produced by this treatment.

RESUMEN

BACKGROUND: From July 1, 1989, through March 31, 2001, 2466 patients with stage I seminoma were evaluated in three randomized noninferiority trials: the TE10, TE18, and TE19 trials. We analyzed mature results of these studies. METHODS: The TE10 trial randomly assigned 478 patients to para-aortic and ipsilateral iliac lymph node (dogleg field) or para-aortic only radiation therapy (total dose = 30 Gy). The TE18 trial randomly assigned 1094 patients to a total dose of 30 or 20 Gy of radiation therapy, predominantly to a para-aortic field. The TE19 trial randomly assigned 1477 patients to radiation therapy or a single injection of carboplatin at a dose of seven times the area under the curve. Time to relapse was determined from Kaplan-Meier curves, and such data were compared by use of Cox regression models. Noninferiority in TE18 and TE19 required the upper limit of the 90% confidence intervals (CIs) (reflecting the one-sided test for noninferiority at a 5% statistical significance level) to exclude a hazard ratio (HR) of greater than 2.0 and a doubling of the 5-year relapse rates observed in the control arm. The TE10 trial was not powered to exclude clinically relevant differences in overall relapse rates but was assessed against the same criteria. RESULTS: Median follow-up times were 6.4-12 years in the three trials. We identified the noninferiority of the following treatments: 20 Gy of radiation therapy in the TE18 trial (HR of relapse = 0.63, 90% CI = 0.38 to 1.04) and carboplatin in the TE19 trial (HR of relapse = 1.25, 90% CI = 0.83 to 1.89). Para-aortic radiation therapy in the TE10 trial was associated with a hazard ratio of relapse of 1.15 (90% CI = 0.54 to 2.44). Relapse occurred after 3 years in only four (0.2%) of all 2466 patients. Computed tomography scans had little impact on the detection of relapse after radiation therapy; seven of the 904 patients allocated radiation therapy in TE19 had a relapse detected by this method. CONCLUSION: This large and mature dataset from three randomized trials has provided support for the use of either radiation therapy or carboplatin therapy as adjuvant treatment for stage I seminoma.

RESUMEN

INTRODUCTION: We present a case of nonseminomatous germ cell tumor of the testes with acute urinary retention secondary to urethral metastasis. This presentation, and similar cases of urethral metastasis from this tumor, have not been reported previously. CASE PRESENTATION: A 35-year-old Caucasian man presented to hospital with a history of acute urinary retention. On examination he was found to have right testicular enlargement with raised ß-human chorionic gonadotrophin, serum α-fetoprotein and lactate dehydrogenase levels. He underwent radical left inguinal orchidectomy and histology confirmed a nonseminomatous germ cell tumor of the testes. Cystoscopy carried out due to urinary retention showed penile metastasis and the biopsy confirmed metastatic malignant undifferentiated teratoma. Staging computed tomography scan and magnetic resonance imaging of the pelvis showed pulmonary, pelvic nodal, ischial and penile metastasis. The diagnosis of the International Germ Cell Cancer Collaborative Group of poor prognosis metastatic nonseminomatous germ cell tumor was made, following which he received four cycles of bleomycin, etoposide and cisplatin chemotherapy with curative intent. He had a complete marker and an excellent radiological response. He is currently under follow up. CONCLUSION: The unusual presentation of lymphovascular spread in this case of nonseminomatous germ cell tumor highlights the need to include routine pelvic imaging in the assessment and follow up of testicular cancer.

RESUMEN

OBJECTIVES: The first consensus report that had been presented by the European Germ Cell Cancer Consensus Group (EGCCCG) in 2004 has found widespread approval by many colleagues throughout the world. In November 2006, the group met a second time under the auspices of the Department of Urology of the Amsterdam Medical Center, The Netherlands. METHODS: Medical oncologists, urologic surgeons, radiation oncologists as well as pathologists from several European countries reviewed and discussed the data that had emerged since the 2002 conference and incorporated the new data into updated and revised guidelines. As for the first meeting the methodology of evidence-based medicine (EBM) was applied. The results of the discussion were compiled by the writing committee. All participants have agreed to this final update. RESULTS: The second part of the consensus paper includes the treatment of metastasised disease, residual tumour resection, salvage therapy, follow-up, and late toxicities. CONCLUSIONS: Whereas the vast majority of the recommendations made in 2004 remain valid 3 yr later, refinements in the treatment of early-stage as well as of advanced-stage testicular cancer have emerged from clinical trials. Despite technical improvements, expert clinical skills will continue to be one of the major determinants for the prognosis of patients with germ cell cancer. In addition, the particular needs of testicular cancer survivors have been acknowledged.
