Dynamics of circulating vascular endothelial growth factor-A predict benefit from antiangiogenic cediranib in metastatic or recurrent cervical cancer patients.

AIMS: There is a need for predictive and surrogate response biomarkers to support treatment with antiangiogenic vascular endothelial growth factor (VEGF) inhibitors. We aimed to identify a minimally-invasive biomarker predicting benefit from cediranib pretreatment or early during treatment in patients with recurrent or metastatic cervical cancer. METHODS: Blood samples were collected before treatment, during treatment and upon disease progression where appropriate from patients enrolled in CIRCCa, a randomised phase II trial of carboplatin and paclitaxel with or without cediranib. Plasma concentrations of VEGF-A, VEGF-receptor 2, Ang1 and Tie2 were measured using multiplex enzyme-linked immunosorbent assay. Pretreatment and temporal changes of the biomarkers were investigated using proportional hazard regression and unsupervised clustering analysis. RESULTS: Samples (n = 556) from 52 patients were analysed. VEGF-receptor 2 (P = .0006) and Tie2 (P = .04) were downregulated following cediranib, while VEGF-A (P = .0025) was upregulated. High Eastern Cooperative Oncology Group performance status (P = .02, hazard ratio [HR] = 2.15, 95% confidence interval [CI] 1.13-4.09) and low pretreatment Tie2 concentrations (P = .003, HR = 0.57, 95%CI 0.39-0.83) were independent prognostic factors associated with reduced progression-free survival. Two patterns of changes in VEGF-A following cediranib were identified. Patients with elevated VEGF-A in the first 3 treatment cycles, regardless of magnitude, had reduced progression-free survival in the placebo arm but improved survival with the addition of cediranib (P = .019, HR = 0.13, 95% CI 0.02-0.71). CONCLUSION: Patterns of early elevation in plasma VEGF-A should be studied further as a potential biomarker to predict treatment benefit from cediranib.

Immediate versus deferred chemotherapy after radical cystectomy in patients with pT3-pT4 or N+ M0 urothelial carcinoma of the bladder (EORTC 30994): an intergroup, open-label, randomised phase 3 trial.

BACKGROUND: Patients with muscle-invasive urothelial carcinoma of the bladder have poor survival after cystectomy. The EORTC 30994 trial aimed to compare immediate versus deferred cisplatin-based combination chemotherapy after radical cystectomy in patients with pT3-pT4 or N+ M0 urothelial carcinoma of the bladder. METHODS: This intergroup, open-label, randomised, phase 3 trial recruited patients from hospitals across Europe and Canada. Eligible patients had histologically proven urothelial carcinoma of the bladder, pT3-pT4 disease or node positive (pN1-3) M0 disease after radical cystectomy and bilateral lymphadenectomy, with no evidence of any microscopic residual disease. Within 90 days of cystectomy, patients were centrally randomly assigned (1:1) by minimisation to either immediate adjuvant chemotherapy (four cycles of gemcitabine plus cisplatin, high-dose methotrexate, vinblastine, doxorubicin, and cisplatin [high-dose MVAC], or MVAC) or six cycles of deferred chemotherapy at relapse, with stratification for institution, pT category, and lymph node status according to the number of nodes dissected. Neither patients nor investigators were masked. Overall survival was the primary endpoint; all analyses were by intention to treat. The trial was closed after recruitment of 284 of the planned 660 patients. This trial is registered with ClinicalTrials.gov, number NCT00028756. FINDINGS: From April 29, 2002, to Aug 14, 2008, 284 patients were randomly assigned (141 to immediate treatment and 143 to deferred treatment), and followed up until the data cutoff of Aug 21, 2013. After a median follow-up of 7.0 years (IQR 5.2-8.7), 66 (47%) of 141 patients in the immediate treatment group had died compared with 82 (57%) of 143 in the deferred treatment group. No significant improvement in overall survival was noted with immediate treatment when compared with deferred treatment (adjusted HR 0.78, 95% CI 0.56-1.08; p=0.13). Immediate treatment significantly prolonged progression-free survival compared with deferred treatment (HR 0.54, 95% CI 0.4-0.73, p<0.0001), with 5-year progression-free survival of 47.6% (95% CI 38.8-55.9) in the immediate treatment group and 31.8% (24.2-39.6) in the deferred treatment group. Grade 3-4 myelosuppression was reported in 33 (26%) of 128 patients who received treatment in the immediate chemotherapy group versus 24 (35%) of 68 patients who received treatment in the deferred chemotherapy group, neutropenia occurred in 49 (38%) versus 36 (53%) patients, respectively, and thrombocytopenia in 36 (28%) versus 26 (38%). Two patients died due to toxicity, one in each group. INTERPRETATION: Our data did not show a significant improvement in overall survival with immediate versus deferred chemotherapy after radical cystectomy and bilateral lymphadenectomy for patients with muscle-invasive urothelial carcinoma. However, the trial is limited in power, and it is possible that some subgroups of patients might still benefit from immediate chemotherapy. An updated individual patient data meta-analysis and biomarker research are needed to further elucidate the potential for survival benefit in subgroups of patients.

Depression and anxiety in long-term cancer survivors compared with spouses and healthy controls: a systematic review and meta-analysis.

BACKGROUND: Cancer survival has improved in the past 20 years, affecting the long-term risk of mood disorders. We assessed whether depression and anxiety are more common in long-term survivors of cancer compared with their spouses and with healthy controls. METHODS: We systematically searched Medline, PsycINFO, Embase, Science Direct, Ingenta Select, Ovid, and Wiley Interscience for reports about the prevalence of mood disorders in patients diagnosed with cancer at least 2 years previously. We also searched the records of the International Psycho-oncology Society and for reports that cited relevant references. Three investigators independently extracted primary data. We did a random-effects meta-analysis of the prevalences of depression and anxiety in cancer patients compared with spouses and healthy controls. FINDINGS: Our search returned 144 results, 43 were included in the main analysis: for comparisons with healthy controls, 16 assessed depression and ten assessed anxiety; of the comparisons with spouses, 12 assessed depression and five assessed anxiety. The prevalence of depression was 11·6% (95% CI 7·7-16·2) in the pooled sample of 51 381 cancer survivors and 10·2% (8·0-12·6) in 217 630 healthy controls (pooled relative risk [RR] 1·11, 95% CI 0·96-1·27; p=0·17). The prevalence of anxiety was 17·9% (95% CI 12·8-23·6) in 48 964 cancer survivors and 13·9% (9·8-18·5) in 226 467 healthy controls (RR 1·27, 95% CI 1·08-1·50; p=0·0039). Neither the prevalence of depression (26·7% vs 26·3%; RR 1·01, 95% CI 0·86-1·20; p=0·88) nor the prevalence of anxiety (28·0% vs 40·1%; RR 0·71, 95% CI 0·44-1·14; p=0·16) differed significantly between cancer patients and their spouses. INTERPRETATION: Our findings suggest that anxiety, rather than depression, is most likely to be a problem in long-term cancer survivors and spouses compared with healthy controls. Efforts should be made to improve recognition and treatment of anxiety in long-term cancer survivors and their spouses. FUNDING: None.

How feasible is implementation of distress screening by cancer clinicians in routine clinical care?

BACKGROUND: There is considerable uncertainty regarding the acceptability of routine distress screening. METHODS: In an unfunded implementation study, the authors asked 50 clinicians (chemotherapy nurses and treatment radiographers/radiation technologists) to implement a screening program for distress as part of routine care and to record their feedback after each clinical encounter. In total, 379 patients were screened using a simple paper-and-pencil versions of distress thermometer and the emotion thermometer (ET). RESULTS: Across all screening applications, clinicians believed that screening was useful during 43% of assessments and was not useful during 35.9% of assessments, and they were unsure or neutral in 21.1% of assessments. The application of the screening program assisted staff in changing their clinical opinion after 41.9% of assessments, and clinicians believed that the screening program helped with communication in >50% of assessments. However, 37.5% believed that screening was impractical for routine use, and more chemotherapy nurses than radiographers rated the screening program as "not useful." On multivariate analysis, 3 variables were associated with high staff satisfaction with screening, namely, receipt of prior training, talking with the patient about psychosocial issues, and improved detection of psychological problems. A favorable perception of screening also was linked to a change in clinical opinion. CONCLUSIONS: Opinions of cancer clinicians regarding routine distress screening were mixed: Approximately 33% considered screening not useful/impractical, whereas >50%n believed promoted good communication and/or helped with recognition. Clinicians who were more positive about screening gained greater benefits from screening in terms of communication and recognition.

Neoadjuvant chemotherapy plus surgery versus surgery for cervical cancer.

BACKGROUND: A previous systematic review found that giving neoadjuvant chemotherapy before surgery improved survival compared with radiotherapy. However, the role of neoadjuvant chemotherapy followed by surgery versus surgery alone is still unclear. OBJECTIVES: To assess the role of neoadjuvant chemotherapy in women with early or locally-advanced cervical cancer. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library) (to Issue 8, 2012), MEDLINE (OVID) (to Aug 2012), LILACS (to Aug 2012), Physician's Data Query (PDQ) (to Aug 2012). We sought both published and unpublished trials and undertook systematic searches of a number of trial sources with no restrictions. SELECTION CRITERIA: Randomised trials comparing neoadjuvant chemotherapy with surgery in women with early or locally-advanced cervical cancer who had not undergone any prior treatment likely to interfere with the treatment comparison. Trials giving radical radiotherapy for inoperable tumours and/or post-operative radiotherapy were also eligible. The primary outcome was overall survival (OS). Secondary outcomes were progression-free survival (PFS), local and distant recurrence, rates of resection and surgical morbidity. DATA COLLECTION AND ANALYSIS: Two authors independently extracted and checked data from trial reports, Depending on the type of outcome, trial hazard ratios (HRs) and odds ratios (ORs) were obtained or estimated from trial reports, or sought from trial investigators. MAIN RESULTS: Six trials (1078 women) were identified for inclusion in this updated review. All six trials provided data on OS (1071 women) and PFS (1027 women). Data on resection rates and pathological response were only available for five trials (908 to 940 women) and data on recurrence were only available for four trials (737 women). Both OS (HR 0.77, 95% confidence interval (CI) 0.62 to 0.96, P = 0.02) and PFS (HR 0.75, 95% CI 0.61 to 0.93, P = 0.008) were significantly improved with neoadjuvant chemotherapy. The estimate for local recurrence was in favour of neoadjuvant chemotherapy (OR 0.67, 95% CI 0.45 to 0.99, P = 0.04), although heterogeneity was observed. The result was no longer significant when the random-effects model was used (OR 0.60, 95% CI 0.32 to 1.12, P = 0.11). Whilst not significant, estimates for distant recurrence (OR 0.72, 95% CI 0.45 to 1.14, P = 0.16) and rates of resection (OR 1.55, 95% CI 0.96 to 2.50, P = 0.07) tended to favour neoadjuvant chemotherapy, although heterogeneity was observed. Exploratory analyses of pathological response showed a significant decrease in adverse pathological findings with neoadjuvant chemotherapy (OR 0.54, 95% CI 0.40 to 0.73, P = < 0.0001 for lymph node status; OR 0.58, 95% CI 0.41 to 0.82, P = 0.002 for parametrial infiltration) which, despite substantial heterogeneity, was still significant when the random-effects model was used. There were also no differences in the effect of neoadjuvant chemotherapy on survival according to total cisplatin dose, chemotherapy cycle length or by cervical cancer stage. AUTHORS' CONCLUSIONS: Both OS and PFS were improved with neoadjuvant chemotherapy. Although the effects were less clear on all other pre-specified outcomes, they all tended to be in favour of neoadjuvant chemotherapy. Whilst these results appear to indicate that neoadjuvant chemotherapy may offer a benefit over surgery alone for women with early-stage or locally-advanced cervical cancer, the evidence is based on only a small number of trials, and further research may be warranted.

Chemotherapy for advanced, recurrent or metastatic endometrial carcinoma.

BACKGROUND: Although endometrial adenocarcinoma is a common gynaecological cancer, a comparatively small proportion of patients present with, or develop, recurrent or advanced disease. However, for those women whose disease does progress or recur the prognosis is poor and the best treatment is yet to be identified. Co-morbidity, including obesity and cardiac disease, and concerns over toxicity have prevented more extensive studies of cytotoxic chemotherapy, although there are a number of active agents. OBJECTIVES: To assess any benefits or adverse effects of cytotoxic chemotherapy in women with advanced, recurrent or metastatic endometrial adenocarcinoma. SEARCH METHODS: Systematic searches of MEDLINE, EMBASE, CENTRAL and the Cochrane Gynaecological Cancer specialist trials register were conducted to identify all eligible randomised controlled trials (RCTs).Databases were searched from 1966 to January 2012. Literature searches were supplemented with searches of relevant trials registers and conference proceedings. SELECTION CRITERIA: RCTs comparing chemotherapy versus another intervention (including different chemotherapy) in advanced disease were considered. Trials of adjuvant treatment or for sarcomatous tumours were excluded. DATA COLLECTION AND ANALYSIS: Data were extracted from the papers by review authors and authors of included studies contacted for further information. MAIN RESULTS: Fourteen eligible trials, which recruited patients between 1974 and 2005, were identified, eight of which compared 'more' with 'less' chemotherapy. Results from these eight trials, including 1519 patients, showed that treatment consisting of 'more' chemotherapy was associated with longer overall survival (OS) (hazard ratio (HR) 0.86; 95% confidence intervals (CI) 0.77 to 0.96; P = 0.005) and with longer progression-free survival (PFS) (n = 1526; HR 0.82; 95% CI 0.74 to 0.90; P < 0.0001). However, serious acute toxicities were more common in women randomised to the more-intense chemotherapy regimens.There was no evidence to suggest that any particular doublet chemotherapy was better (or worse) than any other, or that any single-agent chemotherapy was better (or worse) than another; however, data for these two comparisons were limited. There were no comparative trials of chemotherapy with endocrine therapy or best supportive care alone. AUTHORS' CONCLUSIONS: This review suggests that more-intense chemotherapy regimens may improve both OS and PFS for women with advanced or recurrent endometrial cancer. However, owing to inconsistencies between cytotoxic drug combinations that have been assessed in randomised trials to date, the optimum regimen has still to be defined. Future trials should aim to include measures of quality of life (QoL) and symptom control in addition to survival and progression outcomes.

High weekly integral dose and larger fraction size increase risk of fatigue and worsening of functional outcomes following radiotherapy for localized prostate cancer.

Introduction: We hypothesized that increasing the pelvic integral dose (ID) and a higher dose per fraction correlate with worsening fatigue and functional outcomes in localized prostate cancer (PCa) patients treated with external beam radiotherapy (EBRT). Methods: The study design was a retrospective analysis of two prospective observational cohorts, REQUITE (development, n=543) and DUE-01 (validation, n=228). Data were available for comorbidities, medication, androgen deprivation therapy, previous surgeries, smoking, age, and body mass index. The ID was calculated as the product of the mean body dose and body volume. The weekly ID accounted for differences in fractionation. The worsening (end of radiotherapy versus baseline) of European Organisation for Research and Treatment of Cancer EORTC) Quality of Life Questionnaire (QLQ)-C30 scores in physical/role/social functioning and fatigue symptom scales were evaluated, and two outcome measures were defined as worsening in ≥2 (WS2) or ≥3 (WS3) scales, respectively. The weekly ID and clinical risk factors were tested in multivariable logistic regression analysis. Results: In REQUITE, WS2 was seen in 28% and WS3 in 16% of patients. The median weekly ID was 13.1 L·Gy/week [interquartile (IQ) range 10.2-19.3]. The weekly ID, diabetes, the use of intensity-modulated radiotherapy, and the dose per fraction were significantly associated with WS2 [AUC (area under the receiver operating characteristics curve) =0.59; 95% CI 0.55-0.63] and WS3 (AUC=0.60; 95% CI 0.55-0.64). The prevalence of WS2 (15.3%) and WS3 (6.1%) was lower in DUE-01, but the median weekly ID was higher (15.8 L·Gy/week; IQ range 13.2-19.3). The model for WS2 was validated with reduced discrimination (AUC=0.52 95% CI 0.47-0.61), The AUC for WS3 was 0.58. Conclusion: Increasing the weekly ID and the dose per fraction lead to the worsening of fatigue and functional outcomes in patients with localized PCa treated with EBRT.

The correlation between pre-treatment symptoms, acute and late toxicity and patient-reported health-related quality of life in non-small cell lung cancer patients: Results of the REQUITE study.

BACKGROUND AND PURPOSE: To investigate the association between clinician-scored toxicities and patient-reported health-related quality of life (HRQoL), in early-stage (ES-) and locally-advanced (LA-) non-small cell lung cancer (NSCLC) patients receiving loco-regional radiotherapy, included in the international real-world REQUITE study. MATERIALS AND METHODS: Clinicians scored eleven radiotherapy-related toxicities (and baseline symptoms) with the Common Terminology Criteria for Adverse Events version 4. HRQoL was assessed with the European Organization for Research and Treatment of Cancer core HRQoL questionnaire (EORTC-QLQ-C30). Statistical analyses used the mixed-model method; statistical significance was set at p = 0.01. Analyses were performed for baseline and subsequent time points up to 2 years after radiotherapy and per treatment modality, radiotherapy technique and disease stage. RESULTS: Data of 435 patients were analysed. Pre-treatment, overall symptoms, dyspnea, chest wall pain, dysphagia and cough impacted overall HRQoL and specific domains. At subsequent time points, cough and dysphagia were overtaken by pericarditis in affecting HRQoL. Toxicities during concurrent chemo-radiotherapy and 3-dimensional radiotherapy had the most impact on HRQoL. Conversely, toxicities in sequential chemo-radiotherapy and SBRT had limited impact on patients' HRQoL. Stage impacts the correlations: LA-NSCLC patients are more adversely affected by toxicity than ES-NSCLC patients, mimicking the results of radiotherapy technique and treatment modality. CONCLUSION: Pre-treatment symptoms and acute/late toxicities variously impact HRQoL of ES- and LA-NSCLC patients undergoing different treatment approaches and radiotherapy techniques. Throughout the disease, dyspnea seems crucial in this association, highlighting the additional effect of co-existing comorbidities. Our data call for optimized radiotherapy limiting toxicities that may affect patients' HRQoL.

Overview of health-related quality of life and toxicity of non-small cell lung cancer patients receiving curative-intent radiotherapy in a real-life setting (the REQUITE study).

OBJECTIVES: Radiotherapy-induced toxicity may negatively impact health-related quality of life (HRQoL). This report investigates the impact of curative-intent radiotherapy on HRQoL and toxicity in early stage and locally-advanced non-small cell lung cancer patients treated with radiotherapy or chemo-radiotherapy enrolled in the observational prospective REQUITE study. MATERIALS AND METHODS: HRQoL was assessed using the European Organisation for Research and Treatment of Cancer QLQ-C30 questionnaire up to 2 years post radiotherapy. Eleven toxicities were scored by clinicians using the Common Terminology Criteria for Adverse Events (CTCAE) version 4. Toxicity scores were calculated by subtracting baseline values. Mixed model analyses were applied to determine statistical significance (p ≤ 0.01). Meaningful clinical important differences (MCID) were determined for changes in HRQoL. Analysis was performed on the overall data, different radiotherapy techniques, multimodality treatments and disease stages. RESULTS: Data of 510 patients were analysed. There was no significant change in HRQoL or its domains, except for deterioration in cognitive functioning (p = 0.01). Radiotherapy technique had no significant impact on HRQoL. The addition of chemotherapy was significantly associated with HRQoL over time (p <.001). Overall toxicity did not significantly change over time. Acute toxicities of radiation-dermatitis (p =.003), dysphagia (p =.002) and esophagitis (p <.001) peaked at 3 months and decreased thereafter. Pneumonitis initially deteriorated but improved significantly after 12 months (p =.011). A proportion of patients experienced meaningful clinically important improvements and deteriorations in overall HRQoL and its domains. In some patients, pre-treatment symptoms improved gradually. CONCLUSIONS: While overall HRQoL and toxicity did not change over time, some patients improved, whereas others experienced acute radiotherapy-induced toxicities and deteriorated HRQoL, especially physical and cognitive functioning. Patient characteristics, more so than radiotherapy technique and treatment modality, impact post-radiotherapy toxicity and HRQoL outcomes. This stresses the importance of considering the potential impact of radiotherapy on individuals' HRQoL, symptoms and toxicity in treatment decision-making.

Identification of patient-reported distress by clinical nurse specialists in routine oncology practice: a multicentre UK study.

BACKGROUND: There is uncertainty regarding how well clinical nurse specialists are able to identify distress in cancer settings. METHODS: We examined recognition of patient-reported distress by nurse specialists across three sites in the East Midlands (UK). Clinicians were asked to report on their clinical opinion regarding the presence of distress or any mental health complication after routine assessment of 401 mixed cancer patients. Patient-reported distress was defined by the distress thermometer at a cut-off of 4 or higher. RESULTS: We found that the prevalence of patient-reported distress was 45.4%. The rates for mild, moderate and severe distress were: 23.4, 13.7 and 8.2, respectively. When looking for distress (or any mental health complication) nurse practitioners had a detection sensitivity of 50.5% and specificity 80.0%. Cohen's kappa suggested fair agreement between staff and patients. Examining predictors of distress, clinicians were better able to recognise higher severities of distress (adjusted R(2) =0.87 P=0.001). There was lower sensitivity in palliative stages but no differences according to the type of cancer. There was also higher sensitivity but lower specificity in those clinicians with high self-rated confidence. CONCLUSIONS: Nurses working in cancer settings have difficulty identifying distress using their routine clinical judgement and tend to make more false-negative than false-positive errors. Evidence-based strategies that improve detection of mild and moderate distress are required in routine cancer care.

Desire for psychological support in cancer patients with depression or distress: validation of a simple help question.

OBJECTIVES: Despite documented high rates of psychological distress, it is not clear how to identify those who are willing to accept help. The aim of this study was to investigate whether asking patients receiving chemotherapy if they want help with emotional problems is valuable and to investigate the type of help they want. METHODS: Patients attending a chemotherapy suite were asked to complete the Hospital Anxiety and Depression Scale, the Brief Patient Health Questionnaire (PHQ) and the Emotion Thermometers tools. Results were compared with a single question on desire for help. RESULTS: In this study, 128 patients completed questionnaires for distress, depression, anxiety and desire for help at initial interview. Only one in five unselected patients had a perceived need for help, and in distressed patients only 36% expressed a desire for help. The addition of the help question to the two questions (PHQ-2) about mood and interest improved the ability to rule-in depression by increasing the specificity. However, by addition of this question, sensitivity was significantly reduced. Desire for help was modestly associated with severity of distress, anxiety and depression. CONCLUSIONS: The addition of a help question appears to have limited value in screening for psychological symptoms, but it may highlight those who are willing to accept addition support. Clinicians should attempt to offer a range of psychosocial interventions that will be acceptable to patients with distress.

Can the Distress Thermometer be improved by additional mood domains? Part II. What is the optimal combination of Emotion Thermometers?

PURPOSE: To examine the added value of an algorithmic combination of visual-analogue thermometers compared with the Distress Thermometer (DT) when attempting to detect depression, anxiety or distress in early cancer. METHODS: We report Classification and Regression Tree and logistic regression analyses of the new five-domain Emotion Thermometers tool. This is a combination of five visual-analogue scales in the form of four mood domains (distress, anxiety, depression, anger) as well as need for help. 130 patients attending for their first chemotherapy treatment were assessed. We calculated optimal accuracy for each domain alone and in combination against several criterion standards. RESULTS: When attempting to diagnose depression the Depression Thermometer (DepT) used alone was the optimal approach, but when attempting to detect broadly defined distress or anxiety then a combination of thermometers was most accurate. The DepT was significantly more accurate in detecting depression than the DT. For broadly defined distress a combination of depression, anger and help thermometers was more accurate than the DT alone. For anxiety, while the anxiety thermometer (AnxT) improves upon the DT alone, a combination of the DepT and AnxT are optimal. In each case the optimal strategy allowed the detection of at least an additional 9% of individuals. However, combinations are more laborious to score. In settings where the simplest possible option is preferred the most accurate single thermometer might be preferable as a first stage assessment. CONCLUSION: The DT can be improved by specific combinations of simple thermometers that incorporate depression, anxiety, anger and help.

Can the Distress Thermometer be improved by additional mood domains? Part I. Initial validation of the Emotion Thermometers tool.

PURPOSE: To examine the value of a new screening instrument in a visual-analogue format. METHODS: We report the design and validation of a new five-dimensional tool called the Emotion Thermometers (ET). This is a combination of five visual-analogue scales in the form of four predictor domains (distress, anxiety, depression, anger) and one outcome domain (need for help). Between March and August 2007, 130 patients attending the chemotherapy suite for their first chemotherapy treatment were asked to complete several questionnaires with validation for distress, anxiety and depression. RESULTS: Of 81 with low distress on the Distress Thermometer (DT), 51% recorded emotional difficulties on the new ET tool, suggesting added value beyond the DT alone. Of those with a broadly defined emotional complication, 93.3% could be identified using the Anxiety Thermometer (AnxT) alone, compared with 54.4% who would be recognized using the DT alone. Using a cut-off of 3v4 on all thermometers against the total Hospital Anxiety and Depression Scale (HADS) score (cut-off 14v15), the optimal thermometer was the Anger Thermometer (sensitivity 61%, specificity 92%). Against HADS anxiety scale, the optimal thermometer was AnxT (sensitivity 92%, specificity 61%) and against the HADS depression scale, the optimal thermometer was the Depression Thermometer (DepT; sensitivity 60%, specificity 78%). Finally, against DSM-IV major depression, the optimal thermometer was the DepT (sensitivity 80%, specificity 79%). Further improvements may be possible by using a combination of thermometers or by repeating the screen. CONCLUSION: The diagnostic accuracy of the DT can be improved by the inclusion of simple addition linear domains without substantially increasing the time needed to apply the test.

Neoadjuvant chemotherapy plus surgery versus surgery for cervical cancer.

BACKGROUND: A prior systematic review found that giving neoadjuvant chemotherapy before surgery improved survival compared with radiotherapy. However, the role of neoadjuvant chemotherapy followed by surgery versus surgery alone is still unclear. OBJECTIVES: To assess the role of neoadjuvant chemotherapy in women with early or locally advanced cervical cancer. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), (Issue 2, 2009), MEDLINE (to March 2009), LILACS (to March 2009), Physician's Data Query (PDQ) (to March 2009). Both published and unpublished trials were sought and systematic searches of a number of trial sources were undertaken with no restrictions. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing neoadjuvant chemotherapy with surgery in women with early or locally advanced cervical cancer who had not undergone any prior treatment likely to interfere with the treatment comparison. Trials giving radical radiotherapy for inoperable tumours and/or post-operative radiotherapy were also eligible. The primary outcome was overall survival (OS). Secondary outcomes were progression-free survival (PFS), local and distant recurrence, rates of resection and surgical morbidity. DATA COLLECTION AND ANALYSIS: Data were extracted from trial reports and independently checked by two review authors. Depending on the type of outcome, trial hazard ratios (HRs) and odds ratios (ORs) were obtained or estimated from trial reports or sought from trial investigators. MAIN RESULTS: Six trials (1072 women) were identified for inclusion in the review. Although data on PFS was available for all six trials (1036 women), data on overall survival, resection rates and pathological response were only available for five trials (909 to 938 women) and data on recurrence were only available for three trials (604 women). Whilst PFS was significantly improved with neoadjuvant chemotherapy (HR = 0.76, 95% CI = 0.62 to 0.94, p = 0.01), no OS benefit was observed (HR = 0.85, 95% CI = 0.67 to 1.07, p = 0.17). Furthermore, estimates for both local (OR = 0.76, 95% CI = 0.49 to 1.17, p = 0.21) and distant (OR = 0.68, 95% CI = 0.41 to 1.13, p = 0.13) recurrence and rates of resection (OR = 1.55, 95% CI = 0.96 to 2.50, p = 0.07) only tended to be in favour of neoadjuvant chemotherapy, and heterogeneity was observed. Exploratory analyses of pathological response showed a significant decrease in adverse pathological findings with neoadjuvant chemotherapy (OR = 0.54, 95% CI = 0.39 to 0.73, p = < 0.0001 for lymph node status; OR = 0.58, 95% CI = 0.41 to 0.82, p = 0.002 for parametrial infiltration) which despite a high level of heterogeneity was still significant when the random effects model was used. There was also no difference in the effect of neoadjuvant chemotherapy according to total cisplatin dose, chemotherapy cycle length or by cervical cancer stage. AUTHORS' CONCLUSIONS: Despite outcomes tending to be in favour of neoadjuvant chemotherapy few, including overall survival, were significant. Therefore, it remains unclear whether neoadjuvant chemotherapy consistently offers a benefit over surgery alone for women with early-stage or locally advanced cervical cancer.

Differences in the molecular profile of endometrial cancers from British White and British South Asian women.

OBJECTIVES: To identify differences in the mutational profile of endometrial tumours between British White (BW) and South Asian (BSA) women. METHODS: We analysed primary tumours from matched cohorts of British White (BW) and British South Asian (BSA) women resident in Leicestershire diagnosed with EC. Next Generation Sequencing was performed to investigate mutational differences in a panel of 10 genes previously identified as being commonly mutated in EC. The presence of somatic Mismatch Repair (MMR) gene deficiencies was determined by immunohistochemistry. RESULTS: In total, 57 tumours (27 BSA and 30 BW) were sequenced. There was no significant difference in the overall mutation frequency of the 10 genes analysed; however, numerous differences were observed between the groups. There was a positive association between PIK3CA and PTEN mutations in the BSA group, with 78% of PIK3CA-mutant tumours harbouring a PTEN mutation, whereas only 11% of PIK3CA wild-type (wt) tumours were PTEN mutant positive (p = 0.0012). In BW women, 90% of ARID1A mutant tumours had co-existent PI3K pathway mutations versus 50% of wild-type (wt) ARID1A patients (p = 0.0485). This trend was not significant in the BSA group (p = 0.66). The age at diagnosis was significantly higher in the BW group with a somatic MMR gene deficiency compared to those with no deficiency (72.8 years versus 59.6 years, p = 0.007), whereas this difference was not seen in the BSA group (64 years versus 60 years, p = 0.37). CONCLUSION: We have identified differences in the mutational profile of primary EC tumours from BW and BSA women. Further research is needed to confirm these findings and to explore their potential implications for early detection, treatment response and prognosis.

A Deep Learning Approach Validates Genetic Risk Factors for Late Toxicity After Prostate Cancer Radiotherapy in a REQUITE Multi-National Cohort.

Background: REQUITE (validating pREdictive models and biomarkers of radiotherapy toxicity to reduce side effects and improve QUalITy of lifE in cancer survivors) is an international prospective cohort study. The purpose of this project was to analyse a cohort of patients recruited into REQUITE using a deep learning algorithm to identify patient-specific features associated with the development of toxicity, and test the approach by attempting to validate previously published genetic risk factors. Methods: The study involved REQUITE prostate cancer patients treated with external beam radiotherapy who had complete 2-year follow-up. We used five separate late toxicity endpoints: ≥grade 1 late rectal bleeding, ≥grade 2 urinary frequency, ≥grade 1 haematuria, ≥ grade 2 nocturia, ≥ grade 1 decreased urinary stream. Forty-three single nucleotide polymorphisms (SNPs) already reported in the literature to be associated with the toxicity endpoints were included in the analysis. No SNP had been studied before in the REQUITE cohort. Deep Sparse AutoEncoders (DSAE) were trained to recognize features (SNPs) identifying patients with no toxicity and tested on a different independent mixed population including patients without and with toxicity. Results: One thousand, four hundred and one patients were included, and toxicity rates were: rectal bleeding 11.7%, urinary frequency 4%, haematuria 5.5%, nocturia 7.8%, decreased urinary stream 17.1%. Twenty-four of the 43 SNPs that were associated with the toxicity endpoints were validated as identifying patients with toxicity. Twenty of the 24 SNPs were associated with the same toxicity endpoint as reported in the literature: 9 SNPs for urinary symptoms and 11 SNPs for overall toxicity. The other 4 SNPs were associated with a different endpoint. Conclusion: Deep learning algorithms can validate SNPs associated with toxicity after radiotherapy for prostate cancer. The method should be studied further to identify polygenic SNP risk signatures for radiotherapy toxicity. The signatures could then be included in integrated normal tissue complication probability models and tested for their ability to personalize radiotherapy treatment planning.
