IMPRESS-Norway: improving public cancer care by implementing precision medicine in Norway; inclusion rates and preliminary results.

BACKGROUND AND PURPOSE: In Norway, comprehensive molecular tumour profiling is implemented as part of the public healthcare system. A substantial number of tumours harbour potentially targetable molecular alterations. Therapy outcomes may improve if targeted treatments are matched with actionable genomic alterations. In the IMPRESS-Norway trial (NCT04817956), patients are treated with drugs outside the labelled indication based on their tumours molecular profile. PATIENTS AND METHODS: IMPRESS-Norway is a national, prospective, non-randomised, precision cancer medicine trial, offering treatment to patients with advanced-stage disease, progressing on standard treatment. Comprehensive next-generation sequencing, TruSight Oncology 500, is used for screening. Patients with tumours harbouring molecular alterations with matched targeted therapies available in IMPRESS-Norway, are offered treatment. Currently, 24 drugs are available in the study. Primary study endpoints are percentage of patients offered treatment in the trial, and disease control rate (DCR) defined as complete or partial response or stable disease in evaluable patients at 16 weeks (W16) of treatment. Secondary endpoint presented is DCR in all treated patients. RESULTS: Between April 2021 and October 2023, 1,167 patients were screened, and an actionable mutation with matching drug was identified for 358 patients. By the data cut off 186 patients have initiated treatment, 170 had a minimum follow-up time of 16 weeks, and 145 also had evaluable disease. In patients with evaluable disease, the DCR was 40% (58/145). Secondary endpoint analysis of DCR in all treated patients, showed DCR of 34% (58/170). INTERPRETATION: Precision cancer medicine demonstrates encouraging clinical effect in a subset of patients included in the IMPRESS-Norway trial.

Improving public cancer care by implementing precision medicine in Norway: IMPRESS-Norway.

BACKGROUND: Matching treatment based on tumour molecular characteristics has revolutionized the treatment of some cancers and has given hope to many patients. Although personalized cancer care is an old concept, renewed attention has arisen due to recent advancements in cancer diagnostics including access to high-throughput sequencing of tumour tissue. Targeted therapies interfering with cancer specific pathways have been developed and approved for subgroups of patients. These drugs might just as well be efficient in other diagnostic subgroups, not investigated in pharma-led clinical studies, but their potential use on new indications is never explored due to limited number of patients. METHODS: In this national, investigator-initiated, prospective, open-label, non-randomized combined basket- and umbrella-trial, patients are enrolled in multiple parallel cohorts. Each cohort is defined by the patient's tumour type, molecular profile of the tumour, and study drug. Treatment outcome in each cohort is monitored by using a Simon two-stage-like 'admissible' monitoring plan to identify evidence of clinical activity. All drugs available in IMPRESS-Norway have regulatory approval and are funded by pharmaceutical companies. Molecular diagnostics are funded by the public health care system. DISCUSSION: Precision oncology means to stratify treatment based on specific patient characteristics and the molecular profile of the tumor. Use of targeted drugs is currently restricted to specific biomarker-defined subgroups of patients according to their market authorization. However, other cancer patients might also benefit of treatment with these drugs if the same biomarker is present. The emerging technologies in molecular diagnostics are now being implemented in Norway and it is publicly reimbursed, thus more cancer patients will have a more comprehensive genomic profiling of their tumour. Patients with actionable genomic alterations in their tumour may have the possibility to try precision cancer drugs through IMPRESS-Norway, if standard treatment is no longer an option, and the drugs are available in the study. This might benefit some patients. In addition, it is a good example of a public-private collaboration to establish a national infrastructure for precision oncology.

Clinical experience of volumetric-modulated flattening filter free stereotactic body radiation therapy of lesions in the lung with deep inspiration breath-hold.

This clinical study aimed to evaluate lung cancer patients' ability to perform deep inspiration breath-hold (DIBH) during CT simulation and throughout the treatment course of stereotactic body radiation therapy (SBRT). In addition, target sizes, organ at risk (OAR) sizes, and doses to the respective volumes in filter-free volumetric-modulated arc therapy plans performed under free-breathing (FB) and DIBH conditions were evaluated. Twenty-one patients with peripheral lesions were included, of which 13 were eligible for SBRT. All patients underwent training for breath-hold during CT, and if they complied with the requirements, two CT scans were obtained: CT scan in DIBH and a four-dimensional CT scan in FB. The treatment plans in FB and DIBH were generated, and the dose parameters and volume sizes were compared. The endpoints for evaluation were patient compliance, target dose coverage, and doses to the OARs. This clinical study showed high patient DIBH compliance during both CT simulation and treatment for patients with lung cancer. A significant reduction in target volumes was achieved with SBRT in DIBH, in addition to significantly decreased doses to the heart, chest wall, and lungs. DIBH in SBRT of lung lesions is feasible, and a routine to manage intra-fractional deviation should be established upon implementation.

Second cancers in radically treated Norwegian prostate cancer patients.

Introduction: The aim of this registry-based cohort study was to estimate second cancer (SC) risk following radical prostate cancer (PC) treatment and evaluate if the risk was influenced by radiotherapy. Materials and methods: We collected data from the Cancer Registry of Norway on all patients with PC as first cancer diagnosis, from 1997 to 2014. Standardized incidence ratios (SIRs) for SC were calculated by comparing our cohort to the standard male population. Subdistribution hazard ratios were estimated in treatment groups, using patients treated with radical prostatectomy (RP) as reference. Results: We analyzed 24,592 radically treated PC patients. The median follow-up was 7.75 and 6.25 years in the external beam radiotherapy (EBRT) and RP-groups, respectively. SIR for SC was indifferent from the reference population in 24,592 radically treated patients, higher following EBRT, SIR 1.12 (1.07-1.17), and lower following RP, SIR 0.93 (0.87-0.99). EBRT treated patients had higher rectal and urinary bladder cancer incidences, SIR 1.38 (1.16-1.64) and 1.49 (1.31-1.69), respectively. The EBRT patients and the patients treated with radiation after RP (RT after RP) had 38 and 27% higher risk of any SC. We found higher risk of bladder cancer for all treatment groups as compared to RP patients. Only EBRT treated patients showed higher risk of rectal and lung cancer. Discussion/conclusions: In our study, we found that PC patients treated with EBRT had an increased incidence of SC compared to the general population. Patients treated with EBRT and RT after RP were found to have increased risk of SCs, using RP patients as reference. The risks of rectal and urinary bladder cancer in patients receiving EBRT were higher compared to both the general population and to patients treated with radical prostatectomy. The risk of SC should be taken into account when discussing treatment for patients and designing follow-up.

The Palliative Radiotherapy and Inflammation Study (PRAIS) - protocol for a longitudinal observational multicenter study on patients with cancer induced bone pain.

BACKGROUND: Radiation therapy (RT) results in pain relief for about 6 of 10 patients with cancer induced bone pain (CIBP) caused by bone metastases. The high number of non-responders, the long median time from RT to pain response and the risk of adverse effects, makes it important to determine predictors of treatment response. Clinical features such as cancer type, performance status and pain intensity, and biomarkers for osteoclast activity are proposed as predictors of response to RT. However, results are inconsistent and there is a need for better predictors of RT response. A similar argument can be stated for the development of cachexia; there are currently no predictors that can identify patients who will develop cachexia later in the cancer disease trajectory. Experimental and preclinical studies show that pain, depression and cachexia are related to inflammation. However, it is not known if inflammatory biomarkers can predict CIBP, depression or development of cachexia. METHODS: This multicenter, multinational longitudinal observational study will include 600 adult patients receiving RT for CIBP. Demographic data, clinical variables, osteoclast and inflammatory biomarkers will be assessed before start of RT, and 3, 8, 16, 24 and 52 weeks after last course of RT. The primary aim of the study is to identify potential predictors for pain relief from RT. Secondary aims are to explore potential predictors for development of cachexia, the longitudinal relationship between pain intensity and depression, and if inflammatory biomarkers are associated with changes in pain intensity, cachexia and depression during one-year follow up. DISCUSSION: The immediate clinical implication of the PRAIS study is to identify potential predictive factors for a RT response on CIBP, and thereby reduce non-efficacious RT. Patient benefits are fewer hospital visits, reduced risk of adverse effects and more individualized pain treatment. The long-term clinical implication of the PRAIS study is to improve the knowledge about inflammation in relation to CIBP, cachexia and depression and potentially identify associations and mechanisms that can be targeted for treatment.

Feasibility and preliminary effects of resistance training and nutritional supplements during versus after radiotherapy in patients with head and neck cancer: A pilot randomized trial.

BACKGROUND: Patients with head and neck cancer (HNC) experience involuntary weight loss that has a negative impact on physical function, morbidity, and survival. The objective of the current study was to evaluate the feasibility of an exercise and nutrition intervention during radiotherapy (RT) compared with after RT, and to examine preliminary effects on skeletal muscle mass. METHODS: Patients with HNC were randomized to an exercise and nutrition intervention during RT (EN-DUR) or after RT (EN-AF). The EN-DUR intervention was conducted at a hospital and the EN-AF intervention took place at a rehabilitation center. The interventions consisted of progressive resistance training (PRT) and oral nutritional supplements (ONS). Feasibility outcomes were tracked weekly and muscle mass was measured by computed tomography scans before and after RT and at 2 months follow-up. RESULTS: Of the 50 eligible patients, 41 (82%) agreed to participate. 90% of patients completed the EN-DUR intervention and the adherence to PRT and ONS was 81% and 57%, respectively. 52% of patients attended the EN-AF intervention and adherence to PRT and ONS was 94% and 76%, respectively. The EN-DUR demonstrated a trend toward mitigating loss of muscle mass during RT and the EN-AF demonstrated a similar trend after RT. No difference in muscle mass was detected between the groups from baseline to week 14. CONCLUSIONS: An exercise and nutrition intervention is feasible for patients with HNC during RT, and the intervention is potentially effective in mitigating loss of muscle mass both during and after RT. Future trials should assess the feasibility and effects of extended interventions during and after treatment. Cancer 2017;123:4440-8. © 2017 American Cancer Society.

Intrafractional baseline drift during free breathing breast cancer radiation therapy.

BACKGROUND: Intrafraction motion in breast cancer radiation therapy (BCRT) has not yet been thoroughly described in the literature. It has been observed that baseline drift occurs as part of the intrafraction motion. This study aims to measure baseline drift and its incidence in free-breathing BCRT patients using an in-house developed laser system for tracking the position of the sternum. MATERIALS AND METHODS: Baseline drift was monitored in 20 right-sided breast cancer patients receiving free breathing 3D-conformal RT by using an in-house developed laser system which measures one-dimensional distance in the AP direction. A total of 357 patient respiratory traces from treatment sessions were logged and analysed. Baseline drift was compared to patient positioning error measured from in-field portal imaging. RESULTS: The mean overall baseline drift at end of treatment sessions was -1.3 mm for the patient population. Relatively small baseline drift was observed during the first fraction; however it was clearly detected already at the second fraction. Over 90% of the baseline drift occurs during the first 3 min of each treatment session. The baseline drift rate for the population was -0.5 ± 0.2 mm/min in the posterior direction the first minute after localization. Only 4% of the treatment sessions had a 5 mm or larger baseline drift at 5 min, all towards the posterior direction. Mean baseline drift in the posterior direction in free breathing BCRT was observed in 18 of 20 patients over all treatment sessions. CONCLUSIONS: This study shows that there is a substantial baseline drift in free breathing BCRT patients. No clear baseline drift was observed during the first treatment session; however, baseline drift was markedly present at the rest of the sessions. Intrafraction motion due to baseline drift should be accounted for in margin calculations.

Monitoring deep inspiration breath hold for left-sided localized breast cancer radiotherapy with an in-house developed laser distance meter system.

Deep inspiration breath hold (DIBH) in left-sided breast cancer radiotherapy is a technique to reduce cardiac and pulmonary doses while maintaining target coverage. This study aims at evaluating an in-house developed DIBH system. Free-breathing (FB) and DIBH plans were generated for 22 left-sided localized breast cancer patients who had radiation therapy (RT) after breast-conserving surgery. All patients were treated utilizing an in-house laser distance measuring system. 50 Gy was prescribed, and parameters of interest were target coverage, left anterior descending coronary artery, (LAD) and heart doses. Portal images were acquired and the reproducibility and stability of DIBH treatment were compared to FB. The comparing result shows there is a significant reduction in all LAD and heart dose statistics for DIBH compared to FB plans without compromising the target coverage. The maximum LAD dose was reduced from 43.7 Gy to 29.0 Gy and the volume of the heart receiving >25 Gy was reduced from 3.3% to 1.0% using the in-house system, both statistically significant. The in-house system gave a reproducible and stable DIBH treatment where the systematic error ∑, and random error σ, were less than 2.2 mm in all directions, but were not significantly better than at FB. The system was well tolerated and all patients completed their treatment sessions with DIBH.

Development of a deep inspiration breath-hold system for radiotherapy utilizing a laser distance measurer.

Deep inspiration breath-hold (DIBH) is a technique for treating left-sided breast cancer (LSBC). In modern radiotherapy, one of the main aims is to exclude the heart from the beam aperture with an individualized beam design for LSBC. A deep inhalation will raise the chest wall while the volume of the lungs increase, this will again push the heart away from the breast to be treated. There are a few commercial DIBH systems, both invasive and noninvasive. We present an alternative noninvasive DIBH system based upon an industrial laser distance measurer. This system can be installed in a treatment room at a low cost; it is very easy to use and requires limited amount of training for the personnel and the patient. The system is capable of measuring the position of the chest wall with high frequency and precision in real time. The patient views its breathing curve through video glasses, and gets instructions during the treatment session. The system is well tolerated by test subjects due to its noninvasiveness.

Image guided radiotherapy in curative treatment for prostate cancer. 5-year results from a randomized controlled trial (RIC-trial).

BACKGROUND: Between 2012 and 2015 we conducted a randomized controlled trial in prostate cancer patients comparing weekly 2-D portal imaging versus daily 3-D verification. AIM: To evaluate the clinical outcomes of image guided radiotherapy by presenting rectal and urinary side effects, health related quality of life and progression free survival after 5-years follow up of a randomized controlled trial. METHODS: We randomized 260 men with intermediate or high-risk prostate cancer to weekly 2-D portal imaging with 15 mm margin from CTV to PTV (Arm A) or daily 3-D cone-beam computer tomography with 7 mm margins (Arm B). Prescribed doses were 78 Gy/39 fractions. All patients received hormonal therapy. Primary end point was patient reported bowel symptoms and secondary outcomes were patient reported urinary symptoms, health- related quality of life and progression free survival. RESULTS: Of the 216 patients available for analyses at 5 years more than 90 % completed patient reported outcome measures. There were no significant differences between study arms for any single items nor scales evaluating bowel symptoms. There were also no differences in self-reported urinary symptoms nor in health-related quality of life. Symptom scores were low in both study arms. Progression free survival was similar in Arm B as compared to arm A (Hazard ratio 1.01; 95 % CI 0.57 to 1.97). CONCLUSIONS: Our results support that both 2-D weekly and 3-D daily image guided radiotherapy are safe and efficient treatments for PC and emphasize the need to evaluate technological progress in clinical trials with long follow-up.

Standardizing Integrated Oncology and Palliative Care Across Service Levels: Challenges in Demonstrating Effects in a Prospective Controlled Intervention Trial.

INTRODUCTION: Patients with cancer often want to spend their final days at home. In Norway, most patients with cancer die in institutions. We hypothesized that full integration of oncology and palliative care services would result in more time spent at home during end-of-life. METHODS: A prospective non-randomized intervention trial was conducted in two rural regions of Mid-Norway. The hospitals' oncology and palliative care outpatient clinics and surrounding communities participated. An intervention including information, education, and a standardized care pathway was developed and implemented. Adult non-curative patients with cancer were eligible. Proportion of last 90 days of life spent at home was the primary outcome. RESULTS: We included 129 patients in the intervention group (I) and 76 patients in the comparison group (C), of whom 82% of patients in I and 78% of patients in C died during follow-up. The mean proportion of last 90 days of life spent at home was 0.62 in I and 0.72 in C (p = 0.044), with 23% and 36% (p = 0.073), respectively, dying at home. A higher proportion died at home in both groups compared to pre-study level (12%). During the observation period the comparison region developed and implemented an alternative intervention to the study intervention, with the former more focused on end-of-life care. CONCLUSION: A higher proportion of patients with cancer died at home in both groups compared to pre-study level. Patients with cancer in I did not spend more time at home during end-of-life compared to those in C. The study intervention focused on the whole disease trajectory, while the alternative intervention was more directed towards end-of-life care. "Simpler" and more focused interventions on end-of-life care may be relevant for future studies on integration of palliative care into oncology. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02170168.

Palliative care is an important part of cancer care to improve patients' quality of life. To be cared for and die in the preferred place are quality markers in palliative care. Patients with cancer often want to spend their final days at home. In Norway, most patients with cancer die in institutions. We hypothesized that full integration of cancer and palliative care would result in more time spent at home during end-of-life. An intervention that included information, education, and a standardized care pathway was developed and implemented in a region of Mid-Norway (the intervention region, I). A similar region served as comparison region (C). Adult patients with cancer treated with non-curative intent were eligible. Altogether, 129 patients in I and 76 patients in C were included in the study, of whom 82% in I and 78% in C died during follow-up. The mean proportion of time spent at home last 90 days of life was 0.62 in I and 0.72 in C (p = 0.044), and 22.6% and 35.6% (p = 0.073) died at home, respectively. A higher proportion died at home in both groups compared to pre-study national levels (12%). During the study period, C developed and implemented an alternative intervention to the study intervention, with the former placing more focus on end-of-life care compared to the she study intervention that focused on the whole disease trajectory. This may explain why the intervention did not result in more time spent at home during end-of-life as compared to C. "Simpler" interventions directed towards the study's primary outcome may be relevant for future studies on integration of palliative care into oncology.

Radiotherapy for bone metastases: practice in Norway 1997-2007. A national registry-based study.

UNLABELLED: Numerous randomised clinical trials have shown that the efficacy of single fraction radiotherapy for metastatic bone pain corresponds to that of multiple fractions of radiotherapy for the majority of patients. It is not clear to which extent single fraction radiotherapy has been implemented into clinical practice. MATERIAL AND METHODS: A Norwegian national registry-based study was conducted, including all radiotherapy schedules of 8 Gy × 1 and 3 Gy × 10 delivered to bone metastases in 1997-2007. Binomial regression analyses were used to study whether treatment centre, primary diagnosis, anatomical region irradiated, age, sex, and travel distance, were associated with the choice of fractionation. RESULTS: A total of 14 380 radiotherapy episodes were identified. During the period 31% of the treatments were delivered as 8 Gy × 1. The proportion of single fraction treatments increased from 16% in 1997 to 41% in 2007. There were substantial differences in the proportion of single fraction treatments between the treatment centres (range 25-54%). These differences persisted after adjustment for sex, age, primary diagnosis, anatomical region, and travel distance. CONCLUSIONS: The study demonstrates an underutilisation of single fraction treatment for bone metastases in Norway during the study period.

Barriers and Facilitators When Implementing Electronic Patient-Reported Outcome Measures at a Municipal Cancer Care Unit: A Qualitative Study.

BACKGROUND: Few qualitative studies of barriers and facilitators when implementing electronic patient-reported outcome measure (ePROM) in municipal cancer care exist within the large body of symptom assessment research. Such data, gathered from healthcare professionals' (HCPs) perspective, are central to the development and design of sustainable interventions aiming for a systematic and patient-centered symptom assessment to patients with cancer. OBJECTIVE: The aim of this study was to identify and explore barriers and facilitators, as described by HCPs, in the implementation of the ePROM application "Eir" at a municipal cancer care unit in Norway. METHODS: The study applies a qualitative method, conducting an inductive data inquiry of semistructured individual interviews and focus groups with 14 Norwegian HCPs. Analysis was inspired by thematic analysis as described by Braun and Clarke. RESULTS: The analysis revealed 3 main themes affecting the implementation of ePROM in municipal cancer care: "achieving patient-centered care," "crucial management and training," and "technological barriers." CONCLUSION: The results from this study suggest that HCPs' motivation plays a significant role when implementing ePROM. Motivation of HCPs was strongly influenced by whether the application added value to previously used symptom assessment. Hands-on management and a multiprofessional approach enabled the implementation by facilitating adaptations, training, and resources. IMPLICATIONS FOR PRACTICE: The findings show that adapting the implementation of ePROMs to patient population could be of major importance. Early integration of ePROMs in cancer care could facilitate use throughout the disease trajectory.

NTCP modelling of lung toxicity after SBRT comparing the universal survival curve and the linear quadratic model for fractionation correction.

BACKGROUND: In SBRT of lung tumours no established relationship between dose-volume parameters and the incidence of lung toxicity is found. The aim of this study is to compare the LQ model and the universal survival curve (USC) to calculate biologically equivalent doses in SBRT to see if this will improve knowledge on this relationship. MATERIAL AND METHODS: Toxicity data on radiation pneumonitis grade 2 or more (RP2+) from 57 patients were used, 10.5% were diagnosed with RP2+. The lung DVHs were corrected for fractionation (LQ and USC) and analysed with the Lyman- Kutcher-Burman (LKB) model. In the LQ-correction α/ß = 3 Gy was used and the USC parameters used were: α/ß = 3 Gy, D(0) = 1.0 Gy, [Formula: see text] = 10, α = 0.206 Gy(-1) and d(T) = 5.8 Gy. In order to understand the relative contribution of different dose levels to the calculated NTCP the concept of fractional NTCP was used. This might give an insight to the questions of whether "high doses to small volumes" or "low doses to large volumes" are most important for lung toxicity. RESULTS AND DISCUSSION: NTCP analysis with the LKB-model using parameters m = 0.4, D(50) = 30 Gy resulted for the volume dependence parameter (n) with LQ correction n = 0.87 and with USC correction n = 0.71. Using parameters m = 0.3, D(50) = 20 Gy n = 0.93 with LQ correction and n = 0.83 with USC correction. In SBRT of lung tumours, NTCP modelling of lung toxicity comparing models (LQ,USC) for fractionation correction, shows that low dose contribute less and high dose more to the NTCP when using the USC-model. Comparing NTCP modelling of SBRT data and data from breast cancer, lung cancer and whole lung irradiation implies that the response of the lung is treatment specific. More data are however needed in order to have a more reliable modelling.

Implementing a Standardized Care Pathway Integrating Oncology, Palliative Care and Community Care in a Rural Region of Mid-Norway.

INTRODUCTION: To improve quality across levels of care, we developed a standardized care pathway (SCP) integrating palliative and oncology services for hospitalized and home-dwelling palliative cancer patients in a rural region. METHODS: A multifaceted implementation strategy was directed towards a combination of target groups. The implementation was conducted on a system level, and implementation-related activities were registered prospectively. Adult patients with advanced cancer treated with non-curative intent were included and interviewed. Healthcare leaders (HCLs) and healthcare professionals (HCPs) involved in the development of the SCP or exposed to the implementation strategy were interviewed. In addition, HCLs and HCPs exposed to the implementation strategy answered standardized questionnaires. Hospital admissions were registered prospectively. RESULTS: To assess the use of the SCP, 129 cancer patients were included. Fifteen patients were interviewed about their experiences with the patient-held record (PHR). Sixty interviews were performed among 1320 HCPs exposed to the implementation strategy. Two hundred and eighty-seven HCPs reported on their training in and use of the SCP. Despite organizational cultural differences, developing an SCP integrating palliative and oncology services across levels of care was feasible. Both HCLs and HCPs reported improved quality of care in the wake of the implementation process. Two and a half years after the implementation was launched, 28% of the HCPs used the SCP and 41% had received training in its use. Patients reported limited use and benefit of the PHR. CONCLUSION: An SCP may be a usable tool for integrating palliative and oncology services across care levels in a rural region. An extensive implementation process resulted in improvements of process outcomes, yet still limited use of the SCP in clinical practice. HCLs and HCPs reported improved quality of cancer care following the implementation process. Future research should address mandatory elements for usefulness and successful implementation of SCPs for palliative cancer patients.

When a patient has incurable cancer, it is beneficial to introduce palliative care early in the disease trajectory along with anti-cancer treatment. A standardized care pathway is a method to improve quality and reduce variation in healthcare. It can promote integrated healthcare services in palliative care, e.g. by specifying action points when the patient's situation is changing. In this study, a standardized care pathway for cancer patients with palliative care needs was developed in a rural region of Norway. The pathway focused on patients' needs and symptoms and on smooth transition between levels of care. An educational program and an information strategy were developed to ensure implementation. To evaluate the implementation, all activity regarding the implementation process was registered. Cancer patients and healthcare professionals were interviewed and answered questionnaires. One thousand three hundred and twenty healthcare professionals were exposed to the implementation strategy. One hundred and twenty-nine cancer patients were followed up according to the standardized care pathway. Despite different perspectives of care, it was feasible to develop a standardized care pathway for palliative cancer patients across care settings. A paper-based patient-held record was only found to be useful by a limited number of patients. An extensive implementation process was completed and resulted in improvements regarding healthcare professionals' experience with the quality of cancer care in the region, but limited use of the care pathway in clinical practice. Further research should identify the most important elements for usefulness and successful implementation of the care pathway.

Clinical Predictors for Analgesic Response to Radiotherapy in Patients with Painful Bone Metastases.

BACKGROUND: Radiotherapy (RT) reduces pain in about 60% of patients with painful bone metastases, leaving many patients without clinical benefit. This study assesses predictors for RT effectiveness in patients with painful bone metastases. MATERIALS AND METHODS: We included adult patients receiving RT for painful bone metastases in a multicenter, multinational longitudinal observational study. Pain response within 8 weeks was defined as ≥2-point decrease on a 0-10 pain score scale, without increase in analgesics; or a decrease in analgesics of ≥25% without increase in pain score. Potential predictors were related to patient demographics, RT administration, pain characteristics, tumor characteristics, depression and inflammation (C-reactive protein [CRP]). Multivariate logistic regression analysis with multiple imputation of missing data were applied to identify predictors of RT response. RESULTS: Of 513 eligible patients, 460 patients (90 %) were included in the regression model. 224 patients (44%, 95% confidence interval (CI) 39%-48%) responded to RT. Better Karnofsky performance status (Odds ratio (OR) 1.39, CI 1.15-1.68), breast cancer (OR 2.54, CI 1.12-5.73), prostate cancer (OR 2.83, CI 1.27-6.33) and soft tissue expansion (OR 2.00, CI 1.23-3.25) predicted RT response. Corticosteroids were a negative predictor (OR 0.57, CI 0.37-0.88). Single and multiple fraction RT had similar response. The discriminative ability of the model was moderate; C-statistic 0.69. CONCLUSION: This study supports previous findings that better performance status and type of cancer diagnosis predicts analgesic RT response, and new data showing that soft tissue expansion predicts RT response and that corticosteroids is a negative predictor for RT response in patients with painful bone metastases.

Endocrine treatment, with or without radiotherapy, in locally advanced prostate cancer (SPCG-7/SFUO-3): an open randomised phase III trial.

BACKGROUND: Several studies have shown the efficacy of endocrine therapy in combination with radiotherapy in high-risk prostate cancer. To assess the effect of radiotherapy, we did an open phase III study comparing endocrine therapy with and without local radiotherapy, followed by castration on progression. METHODS: This randomised trial included men from 47 centres in Norway, Sweden, and Denmark. Between February, 1996, and December, 2002, 875 patients with locally advanced prostate cancer (T3; 78%; PSA<70; N0; M0) were centrally randomly assigned by computer to endocrine treatment alone (3 months of total androgen blockade followed by continuous endocrine treatment using flutamide; 439 patients), or to the same endocrine treatment combined with radiotherapy (436 patients). The primary endpoint was prostate-cancer-specific survival, and analysis was by intention to treat. This study is registered as an international standard randomised controlled trial, number ISRCTN01534787. FINDINGS: After a median follow-up of 7.6 years, 79 men in the endocrine alone group and 37 men in the endocrine plus radiotherapy group had died of prostate cancer. The cumulative incidence at 10 years for prostate-cancer-specific mortality was 23.9% in the endocrine alone group and 11.9% in the endocrine plus radiotherapy group (difference 12.0%, 95% CI 4.9-19.1%), for a relative risk of 0.44 (0.30-0.66). At 10 years, the cumulative incidence for overall mortality was 39.4% in the endocrine alone group and 29.6% in the endocrine plus radiotherapy group (difference 9.8%, 0.8-18.8%), for a relative risk of 0.68 (0.52-0.89). Cumulative incidence at 10 years for PSA recurrence was substantially higher in men in the endocrine-alone group (74.7%vs 25.9%, p<0.0001; HR 0.16; 0.12-0.20). After 5 years, urinary, rectal, and sexual problems were slightly more frequent in the endocrine plus radiotherapy group. INTERPRETATION: In patients with locally advanced or high-risk local prostate cancer, addition of local radiotherapy to endocrine treatment halved the 10-year prostate-cancer-specific mortality, and substantially decreased overall mortality with fully acceptable risk of side-effects compared with endocrine treatment alone. In the light of these data, endocrine treatment plus radiotherapy should be the new standard.

Quality of life in patients with locally advanced prostate cancer given endocrine treatment with or without radiotherapy: 4-year follow-up of SPCG-7/SFUO-3, an open-label, randomised, phase III trial.

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.

Physical rehabilitation in patients with head and neck cancer: Impact on health-related quality of life and suitability of a post-treatment program.

OBJECTIVE: Physical rehabilitation programs hold the potential to mitigate deterioration in health-related quality of life (HRQoL) in patients with head and neck cancer. The objective was to assess development in relevant domains of HRQoL following a physical exercise and nutrition intervention administrated during or after treatment. METHODS: In a pilot study, 41 patients were randomized to resistance training and oral nutritional supplements during (EN-DUR, n = 20) or after (EN-AF, n = 21) radiotherapy. Global health status/QoL (GHS) and physical functioning (PF) were measured by the European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaire at baseline, week 6, and week 14. Differences between the groups were assessed by analysis of covariance. A difference of ≥10 points in GHS and PF was interpreted as clinically relevant. RESULTS: No statistically significant differences were detected between the groups; however, clinically relevant changes and differences in GHS and PF were observed. From baseline to week 6, GHS decreased 9 points in the EN-DUR group and 23 points in the EN-AF group and PF decreased 13 points and 21 points, respectively. From week 6 to week 14, GHS increased 14 points in the EN-DUR group and 26 points EN-AF group and PF did not change (0 points) in the EN-DUR group and increased 16 points in the EN-AF group. CONCLUSION: The findings from the present pilot study are promising and indicate that a physical rehabilitation program may have a positive impact on HRQoL during treatment and enhance recovery after treatment. A definitive randomized trial is warranted. LEVEL OF EVIDENCE: 1b-Individual randomized controlled trial.
