Among patients with early-stage Hodgkin's lymphoma who have negative PET findings after three cycles of chemotherapy, radiotherapy produces a 3.8-percentage-point improvement in 3-year progression-free survival. However, 90% of patients are cured by chemotherapy alone. Long-term survival in early-stage Hodgkin’s lymphoma was first made possible by the introduction of the mantle 1 and inverted Y 2 fields of radiotherapy in the 1960s. The addition of adjuvant mechlorethamine, vincristine, procarbazine, and prednisone (MOPP)–like chemotherapies improved progression-free survival rates, 3 but these chemotherapies were associated with severe emesis, 4 gonadal dysfunction, 5 , 6 and in rare cases, secondary leukemia. 7 Evidence of late toxic effects of mantle-field radiotherapy, such as hypothyroidism, 8 second cancers (especially of the breast 9 and lung 10 ), and cardiovascular disease, 11 , 12 also emerged. Thus, it was increasingly apparent that cure was bought at a high price and that less damaging . . .

The role of adjuvant chemotherapy for patients with rectal cancer after preoperative (chemo)radiotherapy and surgery is uncertain. We did a meta-analysis of individual patient data to compare adjuvant chemotherapy with observation for patients with rectal cancer. We searched PubMed, Medline, Embase, Web of Science, the Cochrane Library, CENTRAL, and conference abstracts to identify European randomised, controlled, phase 3 trials comparing observation with adjuvant chemotherapy after preoperative (chemo)radiotherapy and surgery for patients with non-metastatic rectal cancer. The primary endpoint of interest was overall survival. We analysed data from four eligible trials, including data from 1196 patients with (y)pTNM stage II or III disease, who had an R0 resection, had a low anterior resection or an abdominoperineal resection, and had a tumour located within 15 cm of the anal verge. We found no significant differences in overall survival between patients who received adjuvant chemotherapy and those who underwent observation (hazard ratio [HR] 0·97, 95% CI 0·81–1·17; p=0·775); there were no significant differences in overall survival in subgroup analyses. Overall, adjuvant chemotherapy did not significantly improve disease-free survival (HR 0·91, 95% CI 0·77–1·07; p=0·230) or distant recurrences (0·94, 0·78–1·14; p=0·523) compared with observation. However, in subgroup analyses, patients with a tumour 10–15 cm from the anal verge had improved disease-free survival (0·59, 0·40–0·85; p=0·005, pinteraction=0·107) and fewer distant recurrences (0·61, 0·40–0·94; p=0·025, pinteraction=0·126) when treated with adjuvant chemotherapy compared with patients undergoing observation. Overall, adjuvant fluorouracil-based chemotherapy did not improve overall survival, disease-free survival, or distant recurrences. However, adjuvant chemotherapy might benefit patients with a tumour 10–15 cm from the anal verge in terms of disease-free survival and distant recurrence. Further studies of preoperative and postoperative treatment for this subgroup of patients are warranted. None.

Uptake in the national colorectal cancer screening programme in England varies by socioeconomic status. We assessed four interventions aimed at reducing this gradient, with the intention of improving the health benefits of screening. All people eligible for screening (men and women aged 60–74 years) across England were included in four cluster-randomised trials. Randomisation was based on day of invitation. Each trial compared the standard information with the standard information plus the following supplementary interventions: trial 1 (November, 2012), a supplementary leaflet summarising the gist of the key information; trial 2 (March, 2012), a supplementary narrative leaflet describing people's stories; trial 3 (June, 2013), general practice endorsement of the programme on the invitation letter; and trial 4 (July–August, 2013) an enhanced reminder letter with a banner that reiterated the screening offer. Socioeconomic status was defined by the Index of Multiple Deprivation score for each home address. The primary outcome was the socioeconomic status gradient in uptake across deprivation quintiles. This study is registered, number ISRCTN74121020. As all four trials were embedded in the screening programme, loss to follow-up was minimal (less than 0·5%). Trials 1 (n=163 525) and 2 (n=150 417) showed no effects on the socioeconomic gradient of uptake or overall uptake. Trial 3 (n=265 434) showed no effect on the socioeconomic gradient but was associated with increased overall uptake (adjusted odds ratio [OR] 1·07, 95% CI 1·04–1·10, p<0·0001). In trial 4 (n=168 480) a significant interaction was seen with socioeconomic status gradient (p=0·005), with a stronger effect in the most deprived quintile (adjusted OR 1·11, 95% CI 1·04–1·20, p=0·003) than in the least deprived (1·00, 0·94–1·06, p=0·98). Overall uptake was also increased (1·07, 1·03–1·11, p=0·001). Of four evidence-based interventions, the enhanced reminder letter reduced the socioeconomic gradient in screening uptake, but further reducing inequalities in screening uptake through written materials alone will be challenging.

IntroductionAdaptive ChemoTherapy for Ovarian cancer (ACTOv) is a phase II, multicentre, randomised controlled trial, evaluating an adaptive therapy (AT) regimen with carboplatin in women with relapsed, platinum-sensitive high-grade serous or high-grade endometrioid cancer of the ovary, fallopian tube and peritoneum whose disease has progressed at least 6 months after day 1 of the last cycle of platinum-based chemotherapy. AT is a novel, evolutionarily informed approach to cancer treatment, which aims to exploit intratumoral competition between drug-sensitive and drug-resistant tumour subpopulations by modulating drug dose according to a patient’s own response to the last round of treatment. ACTOv is the first clinical trial of AT in this disease setting.Methods and analysis80 patients will be randomised 1:1 to standard therapy (control) or AT (investigational) arms. The starting and maximum carboplatin dose in both arms is area under the curve (AUC) ×5 according to absolute nuclear medicine glomerular filtration rate. The AT regimen will modify the carboplatin dose according to changes in the serum biomarker CA125, a proxy measure of total tumour burden. Patients will receive treatment intravenously every 21 days for a maximum of 6 and 12 cycles in the control and investigational arms, respectively. The primary endpoint is modified progression-free survival (investigator-assessed using RECIST 1.1 (Response Evaluation Criteria in Solid Cancers) compared with the baseline prerandomisation scan rather than the radiological nadir), clinical progression or death from any cause. Secondary endpoints will include acceptability, deliverability, compliance, toxicity, CA125, quality of life and overall survival. ACTOv is open to National Health Service hospitals throughout the UK, recruitment is anticipated to take 36 months across 10 sites and will be managed by the Cancer Research UK and University College London Cancer Trials Centre.Ethics and disseminationThe trial has been reviewed and received approval from the London—Dulwich Research Ethics Committee (REC). Results of the trial will be disseminated through publication in peer-reviewed journals.Trial registration number NCT05080556.

Introduction Increased moderate to vigorous physical activity (MVPA) can improve clinical and psychosocial outcomes for people living with and beyond cancer (LWBC). This study aimed to assess the feasibility and acceptability of trial procedures in a pilot randomised controlled trial (RCT) of a theory‐driven app‐based intervention with behavioural support focused on promoting brisk walking (a form of MVPA) in people LWBC (APPROACH). Methods Participants diagnosed with breast, prostate or colorectal cancer were recruited from a single UK hospital site. Assessments at baseline and 3 months included online questionnaires, device‐measured brisk walking (activPAL accelerometer) and self‐reported weight and height. Participants were randomised to intervention or control (care as usual). The intervention comprised a non‐cancer‐specific app to promote brisk walking (National Health Service ‘Active 10’) augmented with print information about habit formation, a walking planner and two behavioural support telephone calls. Feasibility and acceptability of trial procedures were explored. Initial estimates for physical activity informed a power calculation for a phase III RCT. A preliminary health economics analysis was conducted. Results Of those medically eligible, 369/577 (64%) were willing to answer further eligibility questions and 90/148 (61%) of those eligible were enrolled. Feasibility outcomes, including retention (97%), assessment completion rates (>86%) and app download rates in the intervention group (96%), suggest that the trial procedures are acceptable and that the intervention is feasible. The phase III RCT will require 472 participants to be randomised. As expected, the preliminary health economic analyses indicate a high level of uncertainty around the cost‐effectiveness of the intervention. Conclusions This pilot study demonstrates that a large trial of the brisk walking intervention with behavioural support is both feasible and acceptable to people LWBC. The results support progression onto a confirmatory phase III trial to determine the efficacy and cost‐effectiveness of the intervention.

Strong evidence highlights that sufficient physical activity (PA) has multiple benefits for people living with and beyond cancer. However, many are not meeting PA recommendations. APPROACH is a trial of a theory-driven, app-based behavioral support intervention to promote brisk walking after breast, prostate, or colorectal cancer. The aim of this trial is to evaluate the efficacy and cost-effectiveness of the intervention. APPROACH is a multicenter, phase III, 2-armed, individually randomized controlled trial (N=472). We will recruit patients with localized breast, prostate, or colorectal cancer from hospitals in Yorkshire and surrounding areas in the North of England, United Kingdom, and randomize them 1:1 between the intervention and control arm (usual care). The intervention consists of an app designed for the general population to encourage brisk walking (NHS Active 10), supplemented with habit-based behavioral support, including 2 brief telephone or video calls, a leaflet, website, and walking planners. The primary endpoint is the difference between trial arms in the changes from baseline in activPAL-assessed average minutes of brisk walking (≥100 steps per minute) after 3 months. Demographic and medical characteristics will be collected through self-report and hospital records. Secondary outcomes (assessed at 0, 3, and 6 months) will be the other activPAL-assessed outcomes (brisk walking at 6 months, total steps, light PA, standing time, and sitting times, weekly metabolic equivalent of task), self-reported PA, and self-reported BMI and waist circumference. Patient-reported outcome measures of quality of life, fatigue, sleep, anxiety, depression, self-efficacy, habit strength for walking, and social support will also be collected. Interviews will explore experiences of receiving the intervention. We will use health economic modeling to estimate the cost-effectiveness of the intervention over a lifetime horizon. The study was funded in June 2019. Trial recruitment commenced in November 2023 and is planned to be completed in 2025. As of December 2025, a total of 473 participants have been randomized. The publication of the main results is expected in autumn 2027 after all follow-up data collection and analysis are complete. Overall findings will determine the clinical and cost-effectiveness of the intervention for patients diagnosed with breast, prostate, or colorectal cancer. If successful, APPROACH provides a potential model of supportive care to increase PA among people living with and beyond cancer. ISRCTN Registry ISRCTN14149329; https://www.isrctn.com/ISRCTN14149329.

In England, adults aged 60–74 years are eligible for colorectal cancer screening using a guaiac faecal occult blood test (gFOBt) kit. However, uptake of the gFOBt kit in London has been consistently below the national target. We investigated the effectiveness of a text-message reminder to improve uptake of the test kit in London. General practices in six Clinical Commissioning Groups (CCGs) in London were invited to take part in this randomised controlled trial. Between Jan 18 and March 14, 2016, screening-eligible adults were randomised (1:1, using a pseudorandom number generator) to the control group (gFOBT screening pathway in the English Bowel Cancer Screening Programme [usual care]) or intervention group (usual care plus a text-message reminder). Individuals in the intervention group who had not returned their screening kit were sent a reminder text-message on the eighth week of an 18 week gFOBt screening episode. The primary outcome was the total proportion of individuals returning the kit by 18 weeks, which was determined with intention-to-treat analysis. Ethics approval was given by the East Midlands National Research Ethics Service (15/EM/0159) and the Confidentiality Advisory Group (15/CAG/0156). This trial is registered with ISRCTN, number ISRCTN70904476. 141 (48%) of 295 general practices participated, and 8269 individuals were randomised (4135 usual care, 4134 intervention). Only 49% of individuals in both groups had registered a mobile number with their practice (n=4089). In the intervention group, 1393 individuals with a registered mobile had not returned their test kit within 8 weeks; reminder text-messages were successfully delivered to 1026 individuals (74%), of whom 189 (18%) subsequently took part in screening. Intention-to-treat analysis showed that uptake was 40% (1648 of 4135) in the control and 41% (1674 of 4134) in the intervention group (odds ratio 1·04, 95% CI 0·95–1·13; p=0·43). Pre-planned exploratory subgroup analyses showed no effect on uptake by sex, index of deprivation, age, or CCG. However, a 6 percentage point difference in uptake was seen among individuals receiving an invitation for the first time (control 35% [282/809] vs intervention 41% [297/733]) (odds ratio 1·31, 95% CI 1·00–1·71; p=0·03). Text-message reminders did not significantly increase the number of adequately screened individuals in London. Future research might however investigate the potential efficacy of text-messages among individuals invited for screening for the first time. London North West Healthcare NHS Trust.

Background Uptake of colorectal cancer screening is low in the English NHS Bowel Cancer Screening Programme (BCSP). Participation in screening is strongly associated with socioeconomic status. The aim of this study was to determine whether a supplementary leaflet providing the ‘gist’ of guaiac-based Faecal Occult Blood test (gFOBt) screening for colorectal cancer could reduce the socioeconomic status (SES) gradient in uptake in the English NHS BCSP. Methods The trial was integrated within routine BCSP operations in November 2012. Using a cluster randomised controlled design all adults aged 59–74 years who were being routinely invited to complete the gFOBt were randomised based on day of invitation. The Index of Multiple Deprivation was used to create SES quintiles. The control group received the standard information booklet (‘SI’). The intervention group received the SI booklet and the Gist leaflet (‘SI + Gist’) which had been designed to help people with lower literacy engage with the invitation. Blinding of hubs was not possible and invited subjects were not made aware of a comparator condition. The primary outcome was the gradient in uptake across IMD quintiles. Results In November 2012, 163,525 individuals were allocated to either the ‘SI’ intervention ( n  = 79,104) or the ‘SI + Gist’ group ( n  = 84,421). Overall uptake was similar between the intervention and control groups (SI: 57.3% and SI + Gist: 57.6%; OR = 1.02, 95% CI: 0.92–1.13, p  = 0.77). Uptake was 42.0% (SI) vs. 43.0% (SI + Gist) in the most deprived quintile and 65.6% vs. 65.8% in the least deprived quintile (interaction p  = 0.48). The SES gradient in uptake was similar between the study groups within age, gender, hub and screening round sub-groups. Conclusions Providing supplementary simplified information in addition to the standard information booklet did not reduce the SES gradient in uptake in the NHS BCSP. The effectiveness of the Gist leaflet when used alone should be explored in future research. Trial registration ISRCTN74121020 , registered: 17/20/2012.

Objective. To test the effectiveness of adding a narrative leaflet to the current information material delivered by the NHS English colorectal cancer (CRC) screening programme on reducing socioeconomic inequalities in uptake. Participants. 150,417 adults (59–74 years) routinely invited to complete the guaiac Faecal Occult Blood test (gFOBt) in March 2013. Design. A cluster randomised controlled trial (ISRCTN74121020) to compare uptake between two arms. The control arm received the standard NHS CRC screening information material (SI) and the intervention arm received the standard information plus a supplementary narrative leaflet, which had previously been shown to increase screening intentions (SI + N). Between group comparisons were made for uptake overall and across socioeconomic status (SES). Results. Uptake was 57.7% and did not differ significantly between the two trial arms (SI: 58.5%; SI + N: 56.7%; odds ratio = 0.93; 95% confidence interval: 0.81–1.06; p=0.27). There was no interaction between group and SES quintile (p=0.44). Conclusions. Adding a narrative leaflet to existing information materials does not reduce the SES gradient in uptake. Despite the benefits of using a pragmatic trial design, the need to add to, rather than replace, existing information may have limited the true value of an evidence-based intervention on behaviour.

There remains a lack of consensus as to the most appropriate primary therapy in Waldenstrőm macroglobulinemia (WM). We evaluated a novel bortezomib-based combination and developed a sensitive WM-specific flow cytometry assay (limit of detection 0.004% of leucocytes) to assess bone marrow (BM) response. Sixty treatment-naïve WM patients were enroled into this phase II trial and randomised (2:1) to receive cyclophosphamide and rituximab with either bortezomib (BRC) or fludarabine (FCR). The primary objective was to assess the overall response rate (ORR) in eligible patients receiving BRC ( N  = 41). An ORR of 97.6% (95%CI:87.1–99.9) was observed; 27 (65.9%) patients remain alive without progression after 62.6 months median follow-up, with 2-, 3- and 5-year progression-free survival (PFS) rates of 92.7% (95%CI:79.0–97.6), 80.5% (95%CI:64.8–89.7) and 65.5% (95%CI:48.8–77.9). Persistent WM B-cells were demonstrable in 19/38 patients at the end of treatment (median 0.24%, range 0.02–11.2%). PFS was markedly longer in patients with BM B-cell depletion (<0.004%) compared to those who had persistent BM B-cells detectable at end of treatment (HR = 0.06, 95%CI:0.01–0.47, p  < 0.001), and remained independently associated after adjusting for baseline risk stratification or investigator-assessed response. BRC is a tolerable, highly efficacious regimen for treatment-naïve WM patients. BM B-cell depletion is independently associated with patient outcomes.
