Lymphopenia is frequent in advanced cancers and predicts the toxicity of chemotherapy. Its effect on relapse and survival is uncertain. Its prognostic value for survival was analyzed in three databases of previously reported prospective multicenter studies: (a) FEC chemotherapy in metastatic breast carcinoma; (b) CYVADIC in advanced soft tissue sarcoma (European Organization for Research and Treatment of Cancer-Soft Tissue and Bone Sarcoma Group 62791); and (c) prospective, consecutive phase III studies of aggressive diffuse large-cell non-Hodgkins lymphomas conducted at Centre Léon Bérard between 1987 and 1993. Univariate and multivariate analyses of prognostic factors for survival were performed. The incidence of lymphopenia of <1,000/microL before treatment was constant among the series: 25%, 24%, and 27%, respectively. Lymphopenia was significantly more frequent (P < 0.05) in metastatic breast cancer patients with performance status (PS) of >1, non-Hodgkins lymphoma patients with international prognostic index (IPI) of > 0, and advanced soft tissue sarcoma and metastatic breast cancer patients with bone metastases. Inunivariate analysis, lymphopenia of <1,000/microL significantly correlated to overall survival in patients with metastatic breast cancer (median, 10 versus 14 mo; P < 0.0001), advanced soft tissue sarcoma (median, 5 versus 10 months; P < 0.01), and non-Hodgkin lymphoma (median, 11 versus 94 months; P < 0.0001). In multivariate analysis (Cox model), lymphopenia was an independent prognostic factor for overall survival in metastatic breast cancer [RR (relative risk), 1.8; 95% CI (confidence interval), 1.3-2.4] along with liver metastases and PS; in advanced soft tissue sarcoma (RR, 1.46; 95% CI, 1.0-2.1) along with liver metastases, lung metastases, and PS; and in non-Hodgkins lymphoma (RR, 1.48; 95% CI, 1.03-2.1) along with IPI. Our findings show that lymphopenia is an independent prognostic factor for overall and progression-free survival in several cancers.

BACKGROUND & AIMSnAdjuvant chemotherapy has frequently been associated with weight gain after breast cancer diagnosis. We aimed to prospectively evaluate body weight variations in French patients with early breast cancer.nnnMETHODSnThis prospective observational study included 272 breast cancer patients who were candidates for adjuvant chemotherapy. Weight and body mass index were measured at baseline visit, then at 9 and 15 months from baseline (6 and 12-month post-chemotherapy). At baseline visit, information on the benefits of weight gain prevention and healthy diet was given by a dietician. Univariate logistic regression was performed to test the association between weight gain and potential predictive factors.nnnRESULTSnThirty percent of patients gained weight during the year before diagnosis, 26% were overweight and 15% were obese. At one year, the mean weight change was +1.5kg (SD=4.1) and +2.3% (SD=6.0); 60% of the cohort had gained weight, with a median increase of 3.9kg (SD=3.0) and 5.9% (SD=4.4). Reported weight gain during the year before diagnosis appears to be the only factor associated with the absence of post-chemotherapy weight gain (OR=0.54, 95% CI [0.31-0.95], p=0.034).nnnCONCLUSIONnBody weight increased in the post-chemotherapy period in French breast cancer survivors, even when given dietary recommendations. Appropriate weight management interventions with nutritional follow-up and physical activity programs are needed.

Breast cancer (BC) displays a high heterogeneity from histology to prognosis, metastatic evolution and treatment responses. We report here a (1)H NMR-based metabolic phenotyping study aiming at identifying coordinated metabolic serum changes associated with advanced metastatic breast cancer (MBC) in comparison to the localized early disease (EBC). A model discriminating EBC and MBC patients is obtained (n=85: 46 EBC and 39 MBC), and validated with an independent cohort (n=112: 61 EBC and 51 MBC; 89.8% sensitivity, 79.3% specificity). We identify 9 statistically significant metabolites involved in this discrimination: histidine, acetoacetate, glycerol, pyruvate, glycoproteins (N-acetyl), mannose, glutamate and phenylalanine. This work illustrates the strong potential of NMR metabolic phenotyping for the diagnosis, prognosis, and management of cancer patients.

BackgroundWe aimed to validate prognostic scores for survival in patients undergoing chemotherapy for advanced or metastatic cancer after first-line treatment.MethodsWe previously described two models with good prognostic value based on a combination of Performance Status (PS) and either lactate dehydrogenase (LDH) level or lymphocyte count. These factors were evaluated for their ability to predict overall survival (OS) in a prospective cohort of 299 patients. Clinical and blood parameters were prospectively recorded. Candidate prognostic factors for OS with 0.05 significance level in univariate analysis were included in a multivariate Cox model.ResultsMedian age was 59 years (range: 26-85). Primary tumor sites were breast (45%), lung (15%), ovaries (11%) and others (29%). The number of metastatic sites was 1 (29%), 2 (48%), >2 (23%). Median follow-up and median OS were 12 and 6 months, respectively. Multiple regression analysis confirmed that PS >1, lymphocyte count ≤700/μL and LDH >600 UI/L were independent predictors of short OS, as well as interleukin 6 (IL-6) level, serum albumin concentration and platelet count.ConclusionsPrognostic scores using PS plus LDH level or PS plus lymphocyte count were validated for predicting survival in metastatic cancer patients in relapse beyond first-line treatment. A score combining PS, LDH, lymphocyte and platelet count, serum albumin and IL-6 level was superior in determining patients prognosis.

PurposeDepression occurs among an estimated 15% of cancer patients (range, 1–77.5%). Our main objective was to identify the frequency of reported depression by using the Brief Edinburgh Depression Scale (BEDS) among cancer outpatients. Our secondary objective was to identify associated symptoms of cancer using the Edmonton Symptom Assessment System (ESAS) and to evaluate the screening performance of depression between ESAS and BEDS.MethodsIn this multicenter prospective study conducted, we used the ESAS to collect information on nine symptoms: pain, fatigue, nausea, depression, anxiety, drowsiness, shortness of breath, lack of appetite, and feeling of well-being (each rated from 0 to 10). The BEDS was used to assess for “probable depression” (score >6). Data were analyzed using a parametric and nonparametric test.ResultsA total of 146 patients completed the study. The prevalence of probable depression was 43/146 (29%). Probable depression was associated with increased fatigue (pu2009=u20090.008), depression (pu2009<u20090.0001), anxiety (pu2009<u20090.0001), shortness of breath (pu2009=u20090.01), and decreased feeling of well-being (pu2009<u20090.001). Among patients with probable depression, 42 (98%) patients were not using antidepressants. Regarding the sensitivity and the specificity, we determined that the optimal cutoff for using the ESAS as a depression screening tool was ≥2.ConclusionWe found significant associations between probable depression as determined with the BEDS and five symptoms as detected with the ESAS. The vast majority of patients with probable depression were not receiving pharmacological treatment. Depression should be suspected in patients with higher symptom distress as for any one of these 5 ESAS items.

BackgroundnSeveral studies used the ratio of progression-free survival (PFS) on genotype-matched treatment to PFS on genotype-unmatched treatment to assess the efficacy of therapy guided by patients tumor molecular profiling. We evaluated the PFS ratio from patients who cross-over in the SHIVA trial.nnnPatients and methodsnThe primary end point of the SHIVA trial was to compare PFS on molecularly targeted agents (MTAs) based on tumor molecular profiling and treatment at physicians choice (TPC) in patients with any kind of cancer who had failed standard-of-care therapy. The experimental treatment included only marketed MTAs given outside their indications according to a pre-specified treatment algorithm. Patients were allowed to cross-over at disease progression in both arms. Response was evaluated according to RECIST 1.1 at randomization and at cross-over. We evaluated the ratio of PFS on MTA (PFSMTA) to PFS on TPC (PFSTPC) in patients who crossed-over.nnnResultsnAmong 741 patients enrolled in the SHIVA trial, 197 were randomized, and 95 crossed-over, including 70 patients from the TPC to the MTA arm and 25 patients from the MTA to the TPC arm. Two patients crossed-over in the TPC arm without disease progression. The PFSMTA/PFSTPC ratio exceeded 1.3 in 37% of patients who crossed-over from the TPC to the MTA arm. The PFSMTA/PFSTPC ratio exceeded 1.3 in 61% of patients who crossed-over from the MTA arm to the TPC arm.nnnConclusionsnThe cross-over analysis of the SHIVA trial identified 37% of patients who crossed-over from TPC to MTA with a PFSMTA/PFSTPC ratio exceeding 1.3.

OBJECTIVEnDepression is a frequent problem in cancer patients, which is known to reduce quality of life; however, many cancer patients with depression are not treated because of the difficulties in assessing depression in this population. Our aim was to evaluate and improve the depression assessment strategies of palliative care (PC) physicians and oncologists.nnnMETHODnWe invited all medical oncologists and PC physicians from three cancer centers to participate in this multicenter prospective study. They were asked to classify 22 symptoms (related and specific to depression in cancer patients, related but not specific, and unrelated) as very important, important, less important, or not important for the diagnosis of depression in cancer patients, at three different time points (at baseline, after a video education program, and after 4 weeks). They were also asked to complete a questionnaire exploring physicians perceptions of depression and of their role in its systematic screening.nnnRESULTSnAll 34 eligible physicians participated. Baseline performance was good, with >70% of participants correctly classifying at least seven of nine related and specific symptoms. We found no significant improvement in scores in the immediate and 4-week follow-up tests. Additionally, 24 (83%) and 23 (79%) participants expressed support for systematic depression screening and a role for oncologists in screening, respectively.nnnSIGNIFICANCE OF RESULTSnOncologists had good baseline knowledge about depressions main symptoms in cancer patients and a positive attitude toward being involved in screening. Underdiagnosis of depression is probably related to problems associated with the oncology working environment rather than the physicians knowledge.

Introduction After a diagnosis of localised breast cancer, overweight, obesity and weight gain are negatively associated with prognosis. In contrast, maintaining an optimal weight through a balanced diet combined with regular physical activity appears to be effective protective behaviour against comorbidity or mortality after a breast cancer diagnosis. The primary aim of the Programme pour une Alimentation Saine et une Activité Physique Adaptée pour les patientes atteintes dun cancer du Sein (PASAPAS) randomised controlled trial is to evaluate the feasibility of implementing an intervention of adapted physical activity (APA) for 6u2005months concomitant with the prescription of a first line of adjuvant chemotherapy. Secondary aims include assessing the acceptability of the intervention, compliance to the programme, process implementation, patients’ satisfaction, evolution of biological parameters and the medicoeconomic impact of the intervention. Methods and analysis The study population consists of 60 women eligible for adjuvant chemotherapy after a diagnosis of localised invasive breast cancer. They will be recruited during a 2-year inclusion period and randomly allocated between an APA intervention arm and a control arm following a 2:1 ratio. All participants should benefit from personalised dietetic counselling and patients allocated to the intervention arm will be offered an APA programme of two to three weekly sessions of Nordic walking and aerobic fitness. During the 6-month intervention and 6-month follow-up, four assessments will be performed including blood draw, anthropometrics and body composition measurements, and questionnaires about physical activity level, diet, lifestyle factors, psychological criteria, satisfaction with the intervention and medical data. Ethics and dissemination The study was approved by the French Ethics Committee (Comité de Protection des Personnes Sud-Est IV) and the national agencies for biomedical studies and for privacy. All participants will give written informed consent. The study findings will be disseminated through the scientific public and serve as a foundation for future randomised controlled trials of efficacy.

Purpose/Objective(s) n nBreast cancer (BC) patients with comparable prognostic features have heterogeneous outcomes, partly because of radiotherapy resistance leading to loco-regional recurrences (LRR). The ProfiLER (Profilage LYric et Region, NCT01774409) clinical trial aims at establishing a simple genetic profile of metastatic cancers in order to offer patients personalized molecular targeted therapies. In the breast cancer area, the genomic profiling of a population who ultimately became metastatic, and its correlation with the patient outcome years after LRR, provided an opportunity to identify post hoc biomarkers of the initial radiation resistance. The aim of the present study was to determine if specific tumor genetic alterations were associated with radiation resistance, defined as a LRR despite optimal surgery, radiotherapy, and systemic adjuvant therapies, in a ProfiLER series. n nMaterials/Methods n nGenetic profile of 162 BC patients’ tumors included in ProfiLER between 2013 and 2016 were analyzed using Next-Generation-Sequencing and Comparative-Genomic-Hybridization tests. Patients and tumor characteristics were analyzed for association with genomic rearrangements (mutations, amplification, homozygous deletions). Only gene alterations observed in >3% of the tumors, or included in well-known molecular pathways (PI3 Kinases pathway, MAP Kinases pathway, Tyrosine Kinase receptors family) were selected. The Cox multivariate analysis was based on (P<0.2)-factors in univariate analysis. n nResults n nTwo hundred eighteen genomic rearrangements were identified, and 18 were observed in >3% of tumors. PIK3CA and ROS1 mutations were statistically correlated to the risk of LRR. A median loco-regional progression free survival (LRPFS) of 19.8 years was reported for PIK3CA mutation carriers (n = 34, 21%) versus 9.1 years for wild-type patients (HR = 0.29, 95% CI = 0.13-0.64, P = 0.002 in univariate analysis). PIK3CA mutation was identified as an independent protective factor of LRR using multivariate analysis (HR = 0.27, 95% CI = 0.09-0.82), P = 0.02). ROS1 mutated cancer patients (n = 8, 4.9%) had a median LRPFS of 4 years versus 16.1 years for wild-type patients (HR = 2.5, 95% CI = 1.74-7.05, P = 0.08 in univariate analysis), but was not identified as an independent LRR risk factor (HR = 2.45 95% CI = 0.83-7.26, P = 0.11 in multivariate analysis). Other mutations and amplifications were not associated with LRR. Among relapsing patients, the median time to LRR was nearly significantly different regarding status of the PIK3CA mutations, with 8.6 years for mutated patients versus4.7 years for non-mutated patients (P = 0.09). n nConclusion n nPIK3CA mutation was associated with a lower risk of LRR in this BC population. ROS1 mutation was marginally associated with a higher risk of LRR, possibly because of a limited population. Results suggest PIK3CA and ROS1to be possible biomarkers of radio-sensitivity.
