RESUMO
OBJECTIVES: This study aims to explore the place of the relative in these triadic consultations and how this influences communication. METHODS: A mixed-methods research strategy was used. Triadic consultations for the announcement of cancer progression were recorded and following the 3 participants completed questionnaires comprising mirror-items. Recordings and answers were further investigated in a few semi-structured interviews. Comparison of quantitative responses (questionnaires) used Wilcoxon's test for matched series. Qualitative analyses (consultations, interviews) used grounded theory. Patients were over 18, followed for cancer in palliative phase, excluding brain tumors and malignant hemopathies, and presented renewed disease progression. Relatives were over 18 and authorized by the patient to participate. RESULTS: 47 consultations (audio-recordings, answers to questionnaires) and 12 interviews conducted separately with 4 triads were collected. Half the relatives, while remaining in the background, nevertheless contributed to the discussion. For patients, the presence of a relative was considered beneficial and for oncologists it facilitated the announcement. However, symptoms perceived as intimate or private appeared difficult to express for some patients, and for relatives, prognosis was a difficult subject to broach. Although their relationship with time and their expectations may differ, patients and relatives found consultations positive. Oncologists appeared to underestimate the patient's level of understanding (P<0.001) and perceptions of the seriousness of the disease (P=0.009) but not those of relatives. They did not evaluate the relative's state of health and check what the dyad had retained. SIGNIFICANCE OF RESULTS: Training via simulation sessions should be adapted to communication involving relatives.
RESUMO
PURPOSE: While perioperative chemotherapy provides a survival benefit over surgery alone in gastric and gastroesophageal junction (G/GEJ) adenocarcinomas, the results need to be improved. This study aimed to evaluate the efficacy and safety of perioperative cetuximab combined with 5-fluorouracil and cisplatin. PATIENTS AND METHODS: Patients received six cycles of cetuximab, cisplatin, and simplified LV5FU2 before and after surgery. The primary objective was a combined evaluation of the tumor objective response (TOR), assessed by computed tomography, and the absence of major toxicities resulting in discontinuation of neoadjuvant chemotherapy (NCT) (45% and 90%, respectively). RESULTS: From 2011 to 2013, 65 patients were enrolled. From 64 patients evaluable for the primary endpoint, 19 (29.7%) had a morphological TOR and 61 (95.3%) did not stop NCT prematurely due to major toxicity. Sixty patients (92.3%) underwent resection. Sixteen patients (/56 available, 28.5%) had histological responses (Mandard tumor regression grade ≤3). After a median follow-up of 44.5 months, median disease-free and overall survival were 24.4 [95% CI: 16.4-39.4] and 40.3 months [95% CI: 27.5-NA], respectively. CONCLUSION: Adding cetuximab to the NCT regimen in operable G/GEJ adenocarcinomas is safe, but did not show enough efficacy in the present study to meet the primary endpoint (NCT01360086).
RESUMO
Geriatric assessment (GA) can predict and improve treatment tolerance and estimate overall survival in older patients with cancer. Several international organizations promote GA; however, data related to its implementation in daily clinical practice are still limited. We aimed to describe GA implementation in patients over 75 years old with metastatic prostate cancer treated with docetaxel as first-line treatment, and with positive G8 screening test or frailty criteria. This retrospective real-world study included 224 patients treated from 2014 to 2021 in four French centers, including 131 patients with a theoretical indication of GA. Among the latter, 51 (38.9%) patients had GA. The main barriers to GA were the lack of systematic screening (32/80, 40.0%), unavailability of geriatric physician (20/80, 25.0%), and absence of referral despite a positive screening test (12/80, 15.0%). With GA performed in only one-third of the patients with a theoretical indication in daily clinical practice, mostly due to an absence of screening test, the use of GA is currently sub-optimal.
RESUMO
BACKGROUND/AIMS: The Bretagne-Pays de la Loire cancer observatory, an oncology network created by the French Ministry of Health, is specifically dedicated to assess the use of new targeted anticancer therapies in routine practice. In line with the French National Cancer III program, our cancer network set up a real-life cohort, which is independent of the pharmaceutical industry, for patients with colorectal cancer to monitor patient safety and quality of care and promote pharmacovigilance. MATERIALS AND METHODS: Panitumumab monotherapy was assessed in 243 patients with wild-type Kirsten rat sarcoma who were treated for metastatic colorectal cancer (mCRC) between July 2008 and December 2010 after prior chemotherapy using oxaliplatine and irinotecan. This was a post-European medicine agency marketing (EMA-M) study Results: This study shed light on the best practices, strategic adaptations, clinical results (treatment objective responses, 13%; progression free survival, 2.99 months [2.73-3.15]; and overall survival, 6.8 months [5.49-8.38]) as well as expected or unexpected (grade 3 or 4: 11.5%) secondary effects in the phase IV panitumumab treatment of mCRC. CONCLUSION: Our results are similar to those by Amado whose phase III study led to obtaining EMA-M for panitumumab and tend to confirm the antitumor activity of this antiepidermal growth factor receptor antibody in the treatment of mCRC. In addition, our results opened avenues to further assessment of panitumumab use as monotherapy as well as its benefit-risk ratio while taking into account the patients' general and clinical characteristics. In 2012, the French National Authority for Health appended these data to the panitumumab transparency committee report.

BACKGROUND: Identifying patients with metastatic colorectal cancer who will have an early disease progression during induction chemotherapy (IC) and identifying patients who may have a chemotherapy-free interval (CFI) after IC are two major challenges. METHODS: A logistic model was used to identify factors associated with early progression during IC and with short duration of the first CFI in 488 patients enrolled in the PRODIGE 9 trial. Independent factors were defined with a threshold 0.10. RESULTS: In multivariate analysis, baseline leukocytes >10 × 109/L (OR = 1.98 [1.02-3.8], p = 0.04), and stable or increasing CEA at 2 months (OR = 3.61 [1.68-7.75], p = 0.01) were independent factors associated with progression during IC. Male gender (OR = 1.725 [0.92-3.325], p = 0.09) and no tumour response at first evaluation (OR = 1.90 [0.96-3.76], p = 0.07) were significantly associated with a short CFI. The presence of BRAF V600E mutation was also associated with short CFI (OR = 4.59 [0.95; 22.3], p = 0.058). CONCLUSION: High baseline leukocyte count and the lack of CEA decrease level at first evaluation were associated with early progression, and could be in favour of early chemotherapy intensification. Male gender, no tumour response at first evaluation and BRAF mutation are associated with a short CFI, and may be considered for maintenance chemotherapy after IC. CLINICAL TRIAL NUMBER: NCT00952029.

OBJECTIVE: Diagnostic tests, such as Immunoscore, predict prognosis in patients with colon cancer. However, additional prognostic markers could be detected on pathological slides using artificial intelligence tools. DESIGN: We have developed a software to detect colon tumour, healthy mucosa, stroma and immune cells on CD3 and CD8 stained slides. The lymphocyte density and surface area were quantified automatically in the tumour core (TC) and invasive margin (IM). Using a LASSO algorithm, DGMate (DiGital tuMor pArameTErs), we detected digital parameters within the tumour cells related to patient outcomes. RESULTS: Within the dataset of 1018 patients, we observed that a poorer relapse-free survival (RFS) was associated with high IM stromal area (HR 5.65; 95% CI 2.34 to 13.67; p<0.0001) and high DGMate (HR 2.72; 95% CI 1.92 to 3.85; p<0.001). Higher CD3+ TC, CD3+ IM and CD8+ TC densities were significantly associated with a longer RFS. Analysis of variance showed that CD3+ TC yielded a similar prognostic value to the classical CD3/CD8 Immunoscore (p=0.44). A combination of the IM stromal area, DGMate and CD3, designated 'DGMuneS', outperformed Immunoscore when used in estimating patients' prognosis (C-index=0.601 vs 0.578, p=0.04) and was independently associated with patient outcomes following Cox multivariate analysis. A predictive nomogram based on DGMuneS and clinical variables identified a group of patients with less than 10% relapse risk and another group with a 50% relapse risk. CONCLUSION: These findings suggest that artificial intelligence can potentially improve patient care by assisting pathologists in better defining stage III colon cancer patients' prognosis.

The treatment landscape in metastatic renal cell carcinoma has changed fundamentally over the last decade by the development of antiangiogenic agents, mammalian target of rapamycin inhibitors and immunotherapy. Outside of the context of a clinical trial, the treatments are used sequentially. We describe results under real-life conditions of a sequential treatment strategy, before the era of immunotherapy. All patients were treated according to their prognostic score (either Memorial Sloan Kettering Cancer Center or International Metastatic Renal Cell Carcinoma Database Consortium) for advanced renal cell carcinoma. A treatment strategy involving 1 to 4 lines was determined including a rechallenge criterion for the repeat use of a treatment class. Three hundred forty-four patients were included over 3 years. Overall survival was 57 months in patients with good or intermediate prognosis and 19 months in patients with poor prognosis. In the former group, the proportions of patients treated with 2 to 4 treatment lines were 70%, 38% and 16%, respectively. The best objective response rates for lines 1 to 4 were 46%, 36%, 16% and 17%, respectively. Grade III/IV toxicity did not appear to be cumulative. The recommended strategy was followed in 68% of patients. A large proportion of patients with good or intermediate prognosis who progress after two lines of treatment still have a performance status good enough to receive a systemic treatment, which justifies such a strategy. Overall survival of patients with good and intermediate prognosis was long, suggesting a benefit from the applied approach. These results might be used as selection criterion for the treatment of patients in the era of immune checkpoint inhibitors.

BACKGROUND: Carboplatin and pegylated liposomal doxorubicin combination is a standard regimen in platinum-sensitive recurrent ovarian cancer patients. The pegylated liposomal doxorubicin shortage from 2011 to 2013 urged assessment of the efficacy and tolerance of non-pegylated liposomal doxorubicin in combination with carboplatin. METHODS: MYCA was a multicenter 2-step phase Ib-II single arm trial meant to assess the safety and efficacy of carboplatin AUC 5â¯mg/min.mL combined with non-pegylated liposomal (dose escalation from 40 to 50â¯mg/m2 during phase Ib step; and 50â¯mg/m2 during phase II step), every 4â¯weeks in patients with platinum-sensitive relapse. The primary objective was disease control rate (DCR) at 12â¯months. RESULTS: From 2012 to 2014, 87 patients were enrolled. They were treated as second (78%) or third line (22%) treatment. Total of 67 patients (78%) completed 6â¯cycles. G-CSF support was prescribed to 58% patients. The DCR at 12â¯months was 30.0% (95% CI, 20.3-39.7); the median PFS was 10.0â¯months (95% CI, 8.6-11.0). The median overall survival was 28.1â¯months (95% CI, 22.3-32.5); and the objective response rate was 58% (95% CI, 47-68). Grade 3-4 neutropenia, anemia and thrombocytopenia were observed in 17%, 13% and 1%, respectively; febrile neutropenia in 6%. One patient who did not receive GCSF support died from febrile neutropenia. CONCLUSION: Non-pegylated liposomal doxorubicin-carboplatin combination exhibits an acceptable safety profile, with GCSF prophylaxis. Acknowledging the lack of direct comparison, efficacy in terms of 12â¯month DCR was comparable with standard treatments.

BACKGROUND: Genome-wide association studies (GWAS) have to date identified 94 genetic variants (single nucleotide polymorphisms (SNPs)) associated with risk of developing breast cancer. A score based on the combined effect of the 94 risk alleles can be calculated to measure the global risk of breast cancer. We aimed to test the hypothesis that the 94-SNP-based risk score is associated with clinico-pathological characteristics, breast cancer subtypes and outcomes in early breast cancer. METHODS: A 94-SNP risk score was calculated in 8703 patients in the PHARE and SIGNAL prospective case cohorts. This score is the total number of inherited risk alleles based on 94 selected SNPs. Clinical data and outcomes were prospectively registered. Genotyping was obtained from a GWAS. RESULTS: The median 94-SNP risk score in 8703 patients with early breast cancer was 77.5 (range: 58.1-97.6). The risk score was not associated with usual prognostic and predictive factors (age; tumor, node, metastasis (TNM) status; Scarff-Bloom-Richardson grade; inflammatory features; estrogen receptor status; progesterone receptor status; human epidermal growth factor receptor 2 (HER2) status) and did not correlate with breast cancer subtypes. The 94-SNP risk score did not predict outcomes represented by overall survival or disease-free survival. CONCLUSIONS: In a prospective case cohort of 8703 patients, a risk score based on 94 SNPs was not associated with breast cancer characteristics, cancer subtypes, or patients' outcomes. If we hypothesize that prognosis and subtypes of breast cancer are determined by constitutional genetic factors, our results suggest that a score based on breast cancer risk-associated SNPs is not associated with prognosis.

INTRODUCTION: Gastric neuro-endocrine tumours are rare. European guidelines for the management of neuro-endocrine tumours have been published in 2012. The aim of our survey was to study the management of gastric neuro-endocrine tumours registered in the national cohort. A prospective national cohort registers the Neuro-endocrine tumours in France since January 2003 (GTE network). We reviewed all the individual medical reports of gastric neuro-endocrine tumours in order to collect data on treatment. RESULTS: One hundred and ninety seven gastric neuro-endocrine tumours diagnosed between 1964 and 2013 in 20 centres were registered. For 181 cases data were considered complete for our survey. Eighty four tumours were type 1 (46.4%); five types 2 (2.8%); 52 types 3 (28.7%) and 40 types 4 (22.1%). Types 1 and 2 were first endoscopically managed in 93 and 60% of cases, respectively, whereas surgery was first done in 45 and 42%, respectively, of types 3 and 4. Systemic treatment, chemotherapy and/or somatostatin analogue, was first administered exclusively for types 3 and 4. Near 3% of types 1 and 40% of types 2 received at a time somatostatin analogue treatment. Five-year survival rates were 98.3, 100, 63.2 and 31.8% for types 1, 2, 3 and 4, respectively. CONCLUSION: The great majority of gastric neuro-endocrine tumours registered in this national cohort are treated in accordance with the current guidelines. The survival rates we reported must be interpreted with caution, because this cohort registered preferentially selected patients eligible for treatment. The registration of all the gastric neuro-endocrine tumours, in particular type 1 considered as benign and type 4 not eligible for specific anti-cancer treatment must be encouraged.

Human epidermal growth factor receptor 2-positive breast cancer is a subtype of interest regarding its outcome and the impressive impact of human epidermal growth factor receptor 2 targeted therapy. Constitutional variants may be involved in the aetiology of human epidermal growth factor receptor 2-positive breast cancer, and we propose a case-case study to test the hypothesis that single nucleotide polymorphisms may be associated with human epidermal growth factor receptor 2 status. A Genome-Wide Association Study was used in a cohort of 9836 patients from the SIGNAL/PHARE study (NCT00381901-RECF1098). The main goal was to identify variants specifically related to human epidermal growth factor receptor 2-positive breast cancer. A two-staged genotyping strategy was carried out to cover as large a proportion of the genome as possible. All subjects were genotyped using the Illumina HumanCore Exome chip set. Principal Components Analysis and k-means were then used to characterize the ancestry of the participants. A random sample of subjects from the main "European" cluster was genotyped with the Omni5 chip set. These data were then used to impute missing genotypes from the remaining subjects genotyped only using the HumanCore Exome array. From the 9836 patients, a total of 8703 cases including 3230 patients with human epidermal growth factor receptor 2-positive breast cancer were analyzed. Despite having 80% power to detect an odds ratio of 1.23 in this population, no variant achieved genome-wide significance for association with the occurrence of human epidermal growth factor receptor 2-positive breast cancer vs. any other subtype of breast tumour. Our study was unable to identify constitutional polymorphisms that are strongly associated with human epidermal growth factor receptor 2-positive status among breast cancer patients.
RESUMO
5-Fluorouracil (5-FU)-based treatments can lead to early-onset severe (4%-5%) even fatal (0.3%) toxicities in patients with dihydropyrimidine dehydrogenase (DPD) deficiency. This multicenter prospective cohort study aimed to assess the clinical benefit of pretherapeutic screening for DPD deficiency using a multiparametric approach. Two parallel cohorts of patients treated with 5-FU-based chemotherapy for colorectal carcinoma were compared in a prospective nonrandomized study. In arm A, patients had DPD deficiency screening before treatment, whereas in arm B no pretherapy screening was performed. Dosing was based on 5-FU administration guidelines of each institution. DPD deficiency screening was performed using a combined multiparametric approach (5-FUODPM Tox). The frequency of early grade 4-5 toxic events potentially induced by 5-FU was compared in the two groups. At total of 1,142 patients (n = 1,116 evaluable) were enrolled. In arm A, out of 718 evaluable patients, nine grade 4 early toxicities potentially related to 5-FU were reported in nine patients (1.2%) with no toxic death despite one complete DPD deficiency and 24 partial deficiencies. The 24 patients with partial deficiency had safe pharmacokinetics (PK)-monitored 5-FU. In arm B, among 398 evaluable patients, 17 grade 4-5 toxic early events potentially related to 5-FU were reported in 12 patients (4.2%). The incidence of early severe toxicity was significantly higher in arm B (P = .0019), confirming the positive impact of pretherapeutic DPD assessment. The percent of patients with a toxicity grade 3 or higher observed in arm A was 10.8% (n = 78) compared to 17.55% (n = 69) in arm B (P = .0497). The percentage of death was reduced from 2.5/1,000 in arm B to 0 in arm A. The time to occurrence of all grade ≥3 toxicities was determined in both arms and the difference between the two arms was significant (P = .047). Overall, one patient with complete DPD deficiency confirmed retrospectively died within 13 days from grade 5 multivisceral toxicity. Enrollment was prematurely closed after external experts' decision. In conclusion, multiparametric pretherapeutic DPD deficiency screening significantly lowered the risk of early severe toxicity and avoided an early toxic death. This approach should be used for safe administration of 5-FU-based treatments.

Genetic polymorphisms are associated with breast cancer risk. Clinical and epidemiological observations suggest that clinical characteristics of breast cancer, such as estrogen receptor or HER2 status, are also influenced by hereditary factors. To identify genetic variants associated with pathological characteristics of breast cancer patients, a Genome Wide Association Study was performed in a cohort of 9365 women from the French nationwide SIGNAL/PHARE studies (NCT00381901/RECF1098). Strong association between the FGFR2 locus and ER status of breast cancer patients was observed (ER-positive n=6211, ER-negative n=2516; rs3135718 OR=1.34 p=5.46×10-12). This association was limited to patients with HER2-negative tumors (ER-positive n=4267, ER-negative n=1185; rs3135724 OR=1.85 p=1.16×10-11). The FGFR2 locus is known to be associated with breast cancer risk. This study provides sound evidence for an association between variants in the FGFR2 locus and ER status among breast cancer patients, particularly among patients with HER2-negative disease. This refinement of the association between FGFR2 variants and ER-status to HER2-negative disease provides novel insight to potential biological and clinical influence of genetic polymorphisms on breast tumors.

OBJECTIVE: To evaluate the overall benefits of non-taxane chemotherapies in a non-selected population including unfit patients presenting with symptoms and pain. PATIENTS AND METHODS: This randomized phase II study reports data from 92 patients (52% >70 years old; 40% with a performance score of 2) previously treated with taxane-based chemotherapy, collected from 15 centres in France. Patients received i.v. mitoxantrone (MTX), oral vinorelbine, or oral etoposide, together with oral prednisone. Palliative benefit (pain response without progression of the disease), biological and tumoural responses, and toxicity profile as well as geriatric assessment (in elderly population) were analysed on an intention-to-treat basis. RESULTS: The palliative response rate was 17% for the whole population, and reached 29% when considering the MTX arm. Pain control was achieved in 40% of the patients. The median overall survival was 10.4 months, and was longer in palliative responders. Few grade 3-4 toxicities were observed. The subgroup analysis of elderly patients showed similar results regarding the number and dose intensity of treatments, efficacy and safety. CONCLUSION: In a population including frail and/or elderly patients, who are poorly represented in most clinical studies, non-taxane chemotherapy may remain a relevant option for metastatic prostate cancer having relapsed after a docetaxel-based regimen. Although new treatment options are now approved, the decision-making process should take into account their expected benefit/risk ratio based on the patient status.
