- BACKGROUND: The alpha-emitter radium-223 ((223)Ra) is a bone-seeking radionuclide studied as a new treatment for patients with bone metastases from hormone-refractory prostate cancer. We aimed to study mature outcomes from a randomised, multicentre, phase II study of (223)Ra. METHODS: Patients with hormone-refractory prostate cancer and bone pain needing external-beam radiotherapy were assigned to four intravenous injections of (223)Ra (50 kBq/kg, 33 patients) or placebo (31 patients), given every 4 weeks. Primary endpoints were change in bone-alkaline phosphatase (ALP) concentration and time to skeletal-related events (SREs). Secondary endpoints included toxic effects, time to prostate-specific-antigen (PSA) progression, and overall survival. All tests were done at a 5% significance level, based on intention to treat. FINDINGS: Median relative change in bone-ALP during treatment was -65.6% (95% CI -69.5 to -57.7) and 9.3% (3.8-60.9) in the (223)Ra group and placebo groups, respectively (p<0.0001, Wilcoxon ranked-sums test). Hazard ratio for time to first SRE, adjusted for baseline covariates, was 1.75 (0.96-3.19, p=0.065, Cox regression). Haematological toxic effects did not differ significantly between two groups. No patient discontinued (223)Ra because of treatment toxicity. Median time to PSA progression was 26 weeks (16-39) versus 8 weeks (4-12; p=0.048) for (223)Ra versus placebo, respectively. Median overall survival was 65.3 weeks (48.7-infinity) for (223)Ra and 46.4 weeks (32.1-77.4) for placebo (p=0.066, log rank). The hazard ratio for overall survival, adjusted for baseline covariates was 2.12 (1.13-3.98, p=0.020, Cox regression). INTERPRETATION: (223)Ra was well tolerated with minimum myelotoxicity, and had a significant effect on bone-ALP concentrations. Larger clinical trials are warranted to study (223)Ra on the prevention of SREs and on overall survival in patients with hormone-refractory prostate cancer. Bone-targeting properties of (223)Ra could also potentially be used for treating skeletal metastasis from other primary cancers.

- BACKGROUND: Laparoscopic surgery for colon cancer has been proven safe, but debate continues over whether the available long-term survival data justify implementation of laparoscopic techniques in surgery for colon cancer. The aim of the COlon cancer Laparoscopic or Open Resection (COLOR) trial was to compare 3-year disease-free survival and overall survival after laparoscopic and open resection of solitary colon cancer. METHODS: Between March 7, 1997, and March 6, 2003, patients recruited from 29 European hospitals with a solitary cancer of the right or left colon and a body-mass index up to 30 kg/m(2) were randomly assigned to either laparoscopic or open surgery as curative treatment in this non-inferiority randomised trial. Disease-free survival at 3 years after surgery was the primary outcome, with a prespecified non-inferiority boundary at 7% difference between groups. Secondary outcomes were short-term morbidity and mortality, number of positive resection margins, local recurrence, port-site or wound-site recurrence, and blood loss during surgery. Neither patients nor health-care providers were blinded to patient groupings. Analysis was by intention-to-treat. This trial is registered with ClinicalTrials.gov, number NCT00387842. FINDINGS: During the recruitment period, 1248 patients were randomly assigned to either open surgery (n=621) or laparoscopic surgery (n=627). 172 were excluded after randomisation, mainly because of the presence of distant metastases or benign disease, leaving 1076 patients eligible for analysis (542 assigned open surgery and 534 assigned laparoscopic surgery). Median follow-up was 53 months (range 0.03-60). Positive resection margins, number of lymph nodes removed, and morbidity and mortality were similar in both groups. The combined 3-year disease-free survival for all stages was 74.2% (95% CI 70.4-78.0) in the laparoscopic group and 76.2% (72.6-79.8) in the open-surgery group (p=0.70 by log-rank test); the difference in disease-free survival after 3 years was 2.0% (95% CI -3.2 to 7.2). The hazard ratio (HR) for disease-free survival (open vs laparoscopic surgery) was 0.92 (95% CI 0.74-1.15). The combined 3-year overall survival for all stages was 81.8% (78.4-85.1) in the laparoscopic group and 84.2% (81.1-87.3) in the open-surgery group (p=0.45 by log-rank test); the difference in overall survival after 3 years was 2.4% (95% CI -2.1 to 7.0; HR 0.95 [0.74-1.22]). INTERPRETATION: Our trial could not rule out a difference in disease-free survival at 3 years in favour of open colectomy because the upper limit of the 95% CI for the difference just exceeded the predetermined non-inferiority boundary of 7%. However, the difference in disease-free survival between groups was small and, we believe, clinically acceptable, justifying the implementation of laparoscopic surgery into daily practice. Further studies should address whether laparoscopic surgery is superior to open surgery in this setting.

- In animal models of breast cancer, resistance to continuous use of letrozole can be reversed by withdrawal and reintroduction of letrozole. We therefore hypothesised that extended intermittent use of adjuvant letrozole would improve breast cancer outcome compared with continuous use of letrozole in postmenopausal women.We did the multicentre, open-label, randomised, parallel, phase 3 SOLE trial in 240 centres (academic, primary, secondary, and tertiary care centres) in 22 countries. We enrolled postmenopausal women of any age with hormone receptor-positive, lymph node-positive, and operable breast cancer for which they had undergone local treatment (surgery with or without radiotherapy) and had completed 4-6 years of adjuvant endocrine therapy. They had to be clinically free of breast cancer at enrolment and without evidence of recurrent disease at any time before randomisation. We randomly assigned women (1:1) to treatment groups of either continuous use of letrozole (2·5 mg/day orally for 5 years) or intermittent use of letrozole (2·5 mg/day orally for 9 months followed by a 3-month break in years 1-4 and then 2·5 mg/day during all 12 months of year 5). Randomisation was done by principal investigators or designee at respective centres through the internet-based system of the International Breast Cancer Study Group, was stratified by type of previous endocrine therapy (aromatase inhibitors only vs selective oestrogen receptor modulators only vs both therapies), and used permuted block sizes of four and institutional balancing. No one was masked to treatment assignment. The primary endpoint was disease-free survival, analysed by the intention-to-treat principle using a stratified log-rank test. All patients in the intention-to-treat population who initiated protocol treatment during their period of trial participation were included in the safety analyses. This study is registered with ClinicalTrials.gov, number NCT00553410, and EudraCT, number 2007-001370-88; and long-term follow-up of patients is ongoing.Between Dec 5, 2007, and Oct 8, 2012, 4884 women were enrolled and randomised after exclusion of patients at a non-adherent centre, found to have inadequate documentation of informed consent, immediately withdrew consent, or randomly assigned to intervention groups in error. 4851 women comprised the intention-to-treat population that compared extended intermittent letrozole use (n=2425) with continuous letrozole use (n=2426). After a median follow-up of 60 months (IQR 53-72), disease-free survival was 85·8% (95% CI 84·2-87·2) in the intermittent letrozole group compared with 87·5% (86·0-88·8) in the continuous letrozole group (hazard ratio 1·08, 95% CI 0·93-1·26; p=0·31). Adverse events were reported as expected and were similar between the two groups. The most common grade 3-5 adverse events were hypertension (584 [24%] of 2417 in the intermittent letrozole group vs 517 [21%] of 2411 in the continuous letrozole group) and arthralgia (136 [6%] vs 151 [6%]). 54 patients (24 [1%] in the intermittent letrozole group and 30 [1%] in the continuous letrozole group) had grade 3-5 CNS cerebrovascular ischaemia, 16 (nine [<1%] vs seven [<1%]) had grade 3-5 CNS haemorrhage, and 40 (19 [1%] vs 21 [1%]) had grade 3-5 cardiac ischaemia. In total, 23 (<1%) of 4851 patients died while on trial treatment (13 [<1%] of 2417 patients in the intermittent letrozole group vs ten [<1%] of 2411 in the continuous letrozole group).In postmenopausal women with hormone receptor-positive breast cancer, extended use of intermittent letrozole did not improve disease-free survival compared with continuous use of letrozole. An alternative schedule of extended adjuvant endocrine therapy with letrozole, including intermittent administration, might be feasible and the results of the SOLE trial support the safety of temporary treatment breaks in selected patients who might require them.Novartis and the International Breast Cancer Study Group.

Tidskriftsartikel (refereegranskat)abstract
- Constitutional mismatch repair deficiency (CMMRD) syndrome is a rare and aggressive cancer predisposition syndrome. Because a scarcity of data on this condition contributes to management challenges and poor outcomes, we aimed to describe the clinical spectrum, cancer biology, and impact of genetics on patient survival in CMMRD.In this cohort study, we collected cross-sectional and longitudinal data on all patients with CMMRD, with no age limits, registered with the International Replication Repair Deficiency Consortium (IRRDC) across more than 50 countries. Clinical data were extracted from the IRRDC database, medical records, and physician-completed case record forms. The primary objective was to describe the clinical features, cancer spectrum, and biology of the condition. Secondary objectives included estimations of cancer incidence and of the impact of the specific mismatch-repair gene and genotype on cancer onset and survival, including after cancer surveillance and immunotherapy interventions.We analysed data from 201 patients (103 males, 98 females) enrolled between June 5, 2007 and Sept 9, 2022. Median age at diagnosis of CMMRD or a related cancer was 8·9 years (IQR 5·9-12·6), and median follow-up from diagnosis was 7·2 years (3·6-14·8). Endogamy among minorities and closed communities contributed to high homozygosity within countries with low consanguinity. Frequent dermatological manifestations (117 [93%] of 126 patients with complete data) led to a clinical overlap with neurofibromatosis type 1 (35 [28%] of 126). 339 cancers were reported in 194 (97%) of 201 patients. The cumulative cancer incidence by age 18 years was 90% (95% CI 80-99). Median time between cancer diagnoses for patients with more than one cancer was 1·9 years (IQR 0·8-3·9). Neoplasms developed in 15 organs and included early-onset adult cancers. CNS tumours were the most frequent (173 [51%] cancers), followed by gastrointestinal (75 [22%]), haematological (61 [18%]), and other cancer types (30 [9%]). Patients with CNS tumours had the poorest overall survival rates (39% [95% CI 30-52] at 10 years from diagnosis; log-rank p<0·0001 across four cancer types), followed by those with haematological cancers (67% [55-82]), gastrointestinal cancers (89% [81-97]), and other solid tumours (96% [88-100]). All cancers showed high mutation and microsatellite indel burdens, and pathognomonic mutational signatures. MLH1 or MSH2 variants caused earlier cancer onset than PMS2 or MSH6 variants, and inferior survival (overall survival at age 15 years 63% [95% CI 55-73] for PMS2, 49% [35-68] for MSH6, 19% [6-66] for MLH1, and 0% for MSH2; p<0·0001). Frameshift or truncating variants within the same gene caused earlier cancers and inferior outcomes compared with missense variants (p<0·0001). The greater deleterious effects of MLH1 and MSH2 variants as compared with PMS2 and MSH6 variants persisted despite overall improvements in survival after surveillance or immune checkpoint inhibitor interventions.The very high cancer burden and unique genomic landscape of CMMRD highlight the benefit of comprehensive assays in timely diagnosis and precision approaches toward surveillance and immunotherapy. These data will guide the clinical management of children and patients who survive into adulthood with CMMRD.The Canadian Institutes for Health Research, Stand Up to Cancer, Children's Oncology Group National Cancer Institute Community Oncology Research Program, Canadian Cancer Society, Brain Canada, The V Foundation for Cancer Research, BioCanRx, Harry and Agnieszka Hall, Meagan's Walk, BRAINchild Canada, The LivWise Foundation, St Baldrick Foundation, Hold'em for Life, and Garron Family Cancer Center.

- BACKGROUND: Androgen treatment for prostate cancer can adversely affect functional domains of quality of life. We aimed to assess quality of life in men with locally advanced prostate cancer in an open-label phase III randomised comparison between lifelong endocrine treatment with and without radiotherapy. METHODS: We obtained quality-of-life information from 872 (99%) of 875 eligible men with locally advanced prostate cancer (T3; 78%) who were randomly assigned, between 1996 and 2002, to 3 months of total androgen blockade followed by continuous endocrine treatment (439 patients) or the same hormonal treatment with radiotherapy 3 months after randomisation (436 patients). Prospective outcomes included patient-reported symptoms and quality of life assessed with questionnaires from baseline to 4 years after randomisation. Analysis was by intention to treat. This study is registered as an international standard randomised controlled trial, number ISRCTN01534787. FINDINGS: 438 of 439 men assigned endocrine treatment and 434 of 436 assigned endocrine plus radiotherapy completed at least one questionnaire. Missing data at baseline and during follow-up was equally distributed between groups. At 4 years, 64 (18%) of 353 patients on combined therapy and 39 (12%) of 337 on endocrine-alone therapy had moderate to severe urinary bother (p=0.005), and 16 (4%) of 355 on combined therapy and five (2%) of 338 on endocrine treatment alone had pain while urinating (p=0.024). 37 (11%) of 350 in the combined group and 23 (7%) of 35 in the endocrine-only group had overall bother from all bowel symptoms (p=0.022). 281 (85%) of 332 in the combined-treatment group and 227 (72%) of 313 in the endocrine-only group had erectile dysfunction (p=0.0002). Quality of life at 4 years was similar, with the exception of decreased social function in patients receiving endocrine treatment plus radiotherapy. INTERPRETATION: Although addition of radiotherapy to endocrine treatment significantly increased some treatment-related symptoms, none were serious. Given the substantial survival benefit of combined treatment, the increase of symptoms seems acceptable and has little extra effect on quality of life after 4 years compared with endocrine treatment alone.

- Background Concurrent chemoradiotherapy is standard treatment for limited stage small-cell lung cancer (SCLC). Twice-daily thoracic radiotherapy of 45 Gy in 30 fractions is considered to be the most effective schedule. The aim of this study was to investigate whether high-dose, twice-daily thoracic radiotherapy of 60 Gy in 40 fractions improves survival. Methods This open-label, randomised, phase 2 trial was done at 22 public hospitals in Norway, Denmark, and Sweden. Patients aged 18 years and older with treatment-naive confirmed limited stage SCLC, Eastern Cooperative Oncology Group (ECOG) performance status 0-2, and measurable disease according to the Response Evaluation Criteria in Solid Tumors version 1.1 were eligible. All participants received four courses of intravenous cisplatin 75 ing/m 2 or carboplatin (area under the curve 5-6 mg/mL x min, Calvert's formula) on day 1 and intravenous etoposide 100 mg/m 2 on days 1-3 every 3 weeks. Participants were randomly assigned (1:1) in permuted blocks (sized between 4 and 10) stratifying for ECOG performance status, disease stage, and presence of pleural effusion to receive thoracic radiotherapy of 45 Gy in 30 fractions or 60 Gy in 40 fractions to the primary lung tumour and PET-CT positive lymph node metastases starting 20-28 days after the first chemotherapy course. Patients in both groups received two fractions per day, ten fractions per week. Responders were offered prophylactic cranial irradiation of 25-30 Gy. The primary endpoint, 2-year overall survival, was assessed after all patients had been followed up for a minimum of 2 years. All randomly assigned patients were included in the efficacy analyses, patients commencing thoracic radiotherapy were included in the safety analyses. Follow-up is ongoing. This trial is registered at ClinicalTrials.gov , NCT02041845. Findings Between July 8,2014, and June 6,2018,176 patients were enrolled, 170 of whom were randomly assigned to 60 Gy (n=89) or 45 Gy (n=81). Median follow-up for the primary analysis was 49 months (IQR 38-56). At 2 years, 66 (74.2% [95% CI 63-8-82.9]) patients in the 60 Gy group were alive, compared with 39 (48.1% 136-9-59.51) patients in the 45 Gy group (odds ratio 3.09 [95% CI 1.62-5-89]; p=0-0005). The most common grade 3-4 adverse events were neutropenia (72 [81%] of 89 patients in the 60 Gy group vs 62 181%1 of 77 patients in the 45 Gy group), neutropenic infections (24 [27%] vs 30 [39%1), thrombocytopenia (21 [24%] vs 19 125%1), anaemia (14 [16%] vs 15 120%D, and oesophagitis (19 [21%] vs 14 [18%]). There were 55 serious adverse events in 38 patients in the 60 Gy group and 56 serious adverse events in 44 patients in the 45 Gy group. There were three treatment-related deaths in each group (one neutropenic fever, one aortic dissection, and one pneumonitis in the 60 Gy group; one thrombocytic bleeding, one cerebral infarction, and one myocardial infarction in the 45 Gy group). Interpretation The higher radiotherapy dose of 60 Gy resulted in a substantial survival improvement compared with 45 Gy, without increased toxicity, suggesting that twice-daily thoracic radiotherapy of 60 Gy is an alternative to existing schedules.

- BACKGROUND: For men with localised prostate cancer, surgery provides a survival benefit compared with watchful waiting. Treatments are associated with morbidity. Results for functional outcome and quality of life are rarely reported beyond 10 years and are lacking from randomised settings. We report results for quality of life for men in the Scandinavian Prostate Cancer Group Study Number 4 (SPCG-4) after a median follow-up of more than 12 years.METHODS: All living Swedish and Finnish men (400 of 695) randomly assigned to radical prostatectomy or watchful waiting in SPCG-4 from 1989 to 1999 were included in our analysis. An additional 281 men were included in a population-based control group matched for region and age. Physical symptoms, symptom-induced stress, and self-assessed quality of life were evaluated with a study-specific questionnaire. Longitudinal data were available for 166 Swedish men who had answered quality-of-life questionnaires at an earlier timepoint.FINDINGS: 182 (88%) of 208 men in the radical prostatectomy group, 167 (87%) of 192 men in the watchful-waiting group, and 214 (76%) of 281 men in the population-based control group answered the questionnaire. Men in SPCG-4 had a median follow-up of 12·2 years (range 7-17) and a median age of 77·0 years (range 61-88). High self-assessed quality of life was reported by 62 (35%) of 179 men allocated radical prostatectomy, 55 (34%) of 160 men assigned to watchful waiting, and 93 (45%) of 208 men in the control group. Anxiety was higher in the SPCG-4 groups (77 [43%] of 178 and 69 [43%] of 161 men) than in the control group (68 [33%] of 208 men; relative risk 1·42, 95% CI 1·07-1·88). Prevalence of erectile dysfunction was 84% (146 of 173 men) in the radical prostatectomy group, 80% (122 of 153) in the watchful-waiting group, and 46% (95 of 208) in the control group and prevalence of urinary leakage was 41% (71 of 173), 11% (18 of 164), and 3% (six of 209), respectively. Distress caused by these symptoms was reported significantly more often by men allocated radical prostatectomy than by men assigned to watchful waiting. In a longitudinal analysis of men in SPCG-4 who provided information at two follow-up points 9 years apart, 38 (45%) of 85 men allocated radical prostatectomy and 48 (60%) of 80 men allocated watchful waiting reported an increase in number of physical symptoms; 50 (61%) of 82 and 47 (64%) of 74 men, respectively, reported a reduction in quality of life.INTERPRETATION: For men in SPCG-4, negative side-effects were common and added more stress than was reported in the control population. In the radical prostatectomy group, erectile dysfunction and urinary leakage were often consequences of surgery. In the watchful-waiting group, side-effects can be caused by tumour progression. The number and severity of side-effects changes over time at a higher rate than is caused by normal ageing and a loss of sexual ability is a persistent psychological problem for both interventions. An understanding of the patterns of side-effects and time dimension of their occurrence for each treatment is important for full patient information.

- Cancer research is a crucial pillar for countries to deliver more affordable, higher quality, and more equitable cancer care. Patients treated in research-active hospitals have better outcomes than patients who are not treated in these settings. However, cancer in Europe is at a crossroads. Cancer was already a leading cause of premature death before the COVID-19 pandemic, and the disastrous effects of the pandemic on early diagnosis and treatment will probably set back cancer outcomes in Europe by almost a decade. Recognising the pivotal importance of research not just to mitigate the pandemic today, but to build better European cancer services and systems for patients tomorrow, the Lancet Oncology European Groundshot Commission on cancer research brings together a wide range of experts, together with detailed new data on cancer research activity across Europe during the past 12 years. We have deployed this knowledge to help inform Europe's Beating Cancer Plan and the EU Cancer Mission, and to set out an evidence-driven, patient-centred cancer research roadmap for Europe. The high-resolution cancer research data we have generated show current activities, captured through different metrics, including by region, disease burden, research domain, and effect on outcomes. We have also included granular data on research collaboration, gender of researchers, and research funding. The inclusion of granular data has facilitated the identification of areas that are perhaps overemphasised in current cancer research in Europe, while also highlighting domains that are underserved. Our detailed data emphasise the need for more information-driven and data-driven cancer research strategies and planning going forward. A particular focus must be on central and eastern Europe, because our findings emphasise the widening gap in cancer research activity, and capacity and outcomes, compared with the rest of Europe. Citizens and patients, no matter where they are, must benefit from advances in cancer research. This Commission also highlights that the narrow focus on discovery science and biopharmaceutical research in Europe needs to be widened to include such areas as prevention and early diagnosis; treatment modalities such as radiotherapy and surgery; and a larger concentration on developing a research and innovation strategy for the 20 million Europeans living beyond a cancer diagnosis. Our data highlight the important role of comprehensive cancer centres in driving the European cancer research agenda. Crucial to a functioning cancer research strategy and its translation into patient benefit is the need for a greater emphasis on health policy and systems research, including implementation science, so that the innovative technological outputs from cancer research have a clear pathway to delivery. This European cancer research Commission has identified 12 key recommendations within a call to action to reimagine cancer research and its implementation in Europe. We hope this call to action will help to achieve our ambitious 70:35 target: 70% average survival for all European cancer patients by 2035.
