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.

Following radical orchidectomy for testicular cancer, most patients undergo protocolled surveillance to detect tumour recurrences rather than receive adjuvant chemotherapy. Current United Kingdom national and most international guidelines recommend that patients require a chest x-ray (CXR) and serum tumour markers at each follow-up visit as well as regular CT scans; there is however, variation among cancer centres with follow-up protocols. Seminomas often do not cause tumour marker elevation; therefore, CT scans are the main diagnostic tool for detecting relapse. For non-seminomatous tumours, serum beta-HCG (HCG) and AFP levels are a very sensitive harbinger of relapse, but this only occurs in 50% of patients [1], and therefore, imaging remains as important. CXRs are meant to aid in the detection of lung recurrences and before the introduction of modern cross-sectional imaging in the early 1980s, CXRs would have been the only method of identifying lung metastasis. We examined the Thames Valley and Mount Vernon Cancer Centre databases to evaluate the role of CXRs in the 21st century for the follow-up of men with stage I testicular cancer between 2003 and 2015 to assess its value in diagnosing relapsed germ cell tumours. From a total of 1447 patients, we identified 159 relapses. All relapses were detected either by rising tumour markers or planned follow-up CT scans. Not a single relapse was identified on CXR. We conclude that with timely and appropriate modern cross-sectional imaging and tumour marker assays, the CXR no longer has any value in the routine surveillance of stage I testicular cancer and should be removed from follow-up guidelines and clinical practice. Omitting routine CXR from follow-up schedules will reduce anxiety as well as time that patients spend at hospitals and result in significant cost savings.

Few studies describe supportive care needs among young adults (YAs) with cancer ages 25 to 39 using validated questionnaires. Previous findings identified the need for psychological and information support and suggest that gender, age, psychological distress, and coping may be associated with greater need for this support. To substantiate these findings, this study aimed to (1) describe the supportive care needs of YAs in each domain of the Supportive Care Needs Survey and (2) explore the relationship between unmet supportive care needs and clinical and demographic factors, health-related quality of life, psychological distress, illness cognitions, and service needs using latent class analysis. Clinical teams from six hospitals in England invited eligible patients to a cross-sectional survey by post. A total of 317 participants completed the survey online or on paper. YAs expressed the most need in the psychological and sexuality domains. Using latent class analysis, we identified three classes of YAs based on level of supportive care need: no need (53.3%), low need (28.3%), and moderate need (18.4%). In each class, median domain scores in each domain were similar. Low and moderate need classes were associated with worse health-related quality of life and greater helplessness. Unmet service needs were associated with the moderate-need class only. Patients with unmet supportive care needs should be offered holistic care across supportive care domains.

Background: Bone is the most common site of metastatic disease in advanced prostate cancer. Radium-223 (²²³Ra) is a calcium-mimetic alpha-particle emitter, which has been shown to have activity in prostate cancer with clinical benefit in patients with symptomatic bone metastasis. The recommended schedule is six cycles of ²²³Ra, 5 kBq/kg, at 4-weekly intervals. Although previous studies have assessed clinical outcomes in patients who received six cycles of Ra²²³, there is very little information about outcomes of patients receiving fewer courses of treatment. Patients and Methods: Patients with hormone-refractory metastatic prostate cancer treated from May 2014 to August 2016 were included in this retrospective study. A total of 113 patients were identified with a median age of 76 (range=52-92) years. The median number of cycles administered was 5 (range=1-6) with 54 (48%) completing six cycles of treatment. Eighty-five patients (75%) received ²²³Ra prior to docetaxel chemotherapy and 28 (25%) received it after receiving docetaxel. Results: Eleven patients developed grade 2/3 thrombocytopenia, and none of these received further ²²³Ra. Only 25% of patients who had a haemoglobin level of 10 g/dl or below at the start of the treatment were able to complete six courses of ²²³Ra. Of the patients who completed fewer than six cycles of ²²³Ra (1-5 cycles), the survival was 121 days, compared to 398 days in men who received six cycles (odds ratio(OR)=4.767, 95% confidence internal(CI)=1.07-21.25; p=0.0005). Conclusion: Careful selection of patients is essential to obtain good clinical outcomes from ²²³Ra therapy. When fewer than six cycles were delivered then a beneficial survival effect was not seen.

PURPOSE: Ipilimumab (IPI), in combination with nivolumab (NIVO), is an approved frontline treatment option for patients with intermediate- or poor-risk advanced renal cell carcinoma (aRCC). We conducted a randomized phase II trial to evaluate whether administering IPI once every 12 weeks (modified), instead of once every 3 weeks (standard), in combination with NIVO, is associated with a favorable toxicity profile. METHODS: Treatment-naïve patients with clear-cell aRCC were randomly assigned 2:1 to receive four doses of modified or standard IPI, 1 mg/kg, in combination with NIVO (3 mg/kg). The primary end point was the proportion of patients with a grade 3-5 treatment-related adverse event (trAE) among those who received at least one dose of therapy. The key secondary end point was 12-month progression-free survival (PFS) in the modified arm compared with historical sunitinib control. The study was not designed to formally compare arms for efficacy. RESULTS: Between March 2018 and January 2020, 192 patients (69.8% intermediate/poor-risk) were randomly assigned and received at least one dose of study drug. The incidence of grade 3-5 trAEs was significantly lower among participants receiving modified versus standard IPI (32.8% v 53.1%; odds ratio, 0.43 [90% CI, 0.25 to 0.72]; P = .0075). The 12-month PFS (90% CI) using modified IPI was 46.1% (38.6 to 53.2). At a median follow-up of 21 months, the overall response rate was 45.3% versus 35.9% and the median PFS was 10.8 months versus 9.8 months in the modified and standard IPI groups, respectively. CONCLUSION: Rates of grade 3-5 trAEs were significantly lower in patients receiving modified versus standard IPI. Although 12-month PFS did not meet the prespecified efficacy threshold compared with historical control, informal comparison of treatment groups did not suggest any reduction in efficacy with the modified schedule.
