Lung Transplantation in Pulmonary Arterial Hypertension: The Portuguese Experience.

BACKGROUND: In patients with pulmonary arterial hypertension (PAH), refractory to medical therapy, lung transplantation emerges as an option. This study describes the outcomes of 8 PAH patients who underwent lung transplantation. METHODS: A retrospective, single-center study was conducted among patients with PAH who underwent lung transplantation in our center. RESULTS: Patients had a median age of 46 years, with female sex predominance (75%). Causes of HAP were pulmonary veno-occlusive disease (n = 5, 62.5%), idiopathic PAH (n = 2, 25%), and heritable PAH (n = 1, 12.5%). Pre-transplant hemodynamics revealed a median mean pulmonary artery pressure of 58.5 mm Hg (48-86). All patients received bilateral lung transplants with extracorporeal membrane oxygenation support, displaying immediate post-transplant hemodynamic improvement. Primary graft dysfunction grade 3 (PGD 3) was observed in 75% of patients. Five patients (62.5%) died, with a 72.9% survival at 12 months and 29.2% at 24 months post-transplantation. CONCLUSION: Our study reveals the complexity and challenges of lung transplants in patients with PAH. Despite notable immediate hemodynamic improvements, high rates of PGD 3 and the survival rate remain a concern. Further research to define optimal peri and post-transplant management to improve survival is required.

New Insights into the Dermocosmetic Potential of the Red Seaweed Gelidium corneum.

This work addresses the potential of the red seaweed Gelidium corneum as a source of bioactive ingredients for skin health and wellness in response to the growing awareness regarding the significance of sustainable strategies in developing new nature-based dermocosmetic products. Hydroalcoholic extracts from the dried biomass were subjected to sequential liquid-liquid partitions, affording five different fractions (F1-F5). Their cosmetic potential was assessed through a set of in vitro assays concerning their antioxidant, photoprotective, and healing properties. Additionally, their cytotoxicity in HaCaT cells and their capacity to induce inflammation in RAW 264.7 cells were also evaluated. As a proof-of-concept, O/W emulsions were prepared, and emulsion stability was assessed by optical microscopy, droplet size analysis, centrifugation tests, and rheology analysis. Furthermore, in vivo tests were conducted with the final formulation to assess its antioxidant capacity. At subtoxic concentrations, the most lipophilic fraction has provided photoprotection against UV light-induced photooxidation in HaCaT cells. This was conducted together with the aqueous fraction, which also displayed healing capacities. Regarding the physical and stability assays, the best performance was achieved with the formulation containing 1% aqueous extract, which exhibited water retention and antioxidant properties in the in vivo assay. In summary, Gelidium corneum displayed itself as a potential source of bioactive ingredients with multitarget properties for dermatological use.

Facing points of view: Representations on adjuvant endocrine therapy of premenopausal patients after breast cancer and their healthcare providers in France. The FOR-AD study.

PURPOSE: Adjuvant endocrine therapy (ET) for 5-10 years is the backbone of the therapeutic strategy in patients with hormone receptor positive (HR+) early breast cancer (BC). However, long-term adherence to adjuvant ET represents a major challenge for most patients. According to prior studies, side effects of adjuvant ET are an important reason for poor adherence. In contrast, better communication and relational bond between patients and healthcare providers (HCPs) may improve adherence. The FOR-AD (Focus on non-adherence) study aimed at better understanding the representation of adjuvant ET by patients and their HCPs, in order to improve the care process. METHODS: Three focus groups of premenopausal women (receiving adjuvant ET for variable amount of time) and two focus groups of HCPs (including oncologists, pharmacists, and nurses) were conducted, each including around ten participants. Thematic analyses using a general inductive approach were constructed to report participants' representations. RESULTS: Two main themes emerged across groups, and appeared of major importance. Representations on adjuvant ET were often homogenous within each group, but differed between patients and their HCPs. The relationship between both groups was considerably discussed, particularly its importance in facilitating adherence to adjuvant ET. Suggestions on improving the care process were also given, such as systematically including psychologists in follow-up care paths and having a nurse navigator follow patients under treatment with adjuvant ET. CONCLUSION: The present qualitative exploration may help buildi future tailored interventions to improve adherence to adjuvant ET, in particular regarding the role of nurse navigators.

Gelidiales Are Not Just Agar-Revealing the Antimicrobial Potential of Gelidium corneum for Skin Disorders.

In recent decades, seaweeds have proven to be an excellent source of bioactive molecules. Presently, the seaweed Gelidium corneum is harvested in a small area of the Portuguese coast exclusively for agar extraction. The aim of this work was to fully disclosure Gelidium corneum as a sustainable source of antimicrobial ingredients for new dermatological formulations, highlighting its potential to be explored in a circular economy context. For this purpose, after a green sequential extraction, these seaweed fractions (F1-F5) were chemically characterized (1H NMR) and evaluated for their antimicrobial potential against Staphylococcus aureus, Staphylococcus epidermidis and Cutibacterium acnes. The most active fractions were also evaluated for their effects on membrane potential, membrane integrity and DNA damage. Fractions F2 and F3 displayed the best results, with IC50 values of 16.1 (7.27-23.02) µg/mL and 51.04 (43.36-59.74) µg/mL against C. acnes, respectively, and 53.29 (48.75-57.91) µg/mL and 102.80 (87.15-122.30) µg/mL against S. epidermidis, respectively. The antimicrobial effects of both fractions seem to be related to membrane hyperpolarization and DNA damage. This dual mechanism of action may provide therapeutic advantages for the treatment of skin dysbiosis-related diseases.

[Teleconsultation in the Portuguese National Health Service During the COVID-19 Pandemic: A Survey of Physicians' Views and Future Implications]. / Consulta Não Presencial no Serviço Nacional de Saúde Português Durante a Pandemia de COVID-19: Estudo da Opinião dos Médicos e Implicações para o Futuro.

INTRODUCTION: The COVID-19 pandemic led to the reorganization of healthcare services and teleconsultation emerged as a solution to facilitate patient appointments. The aim of this study was to characterize, from a physician perspective, the teleconsultations carried out in the Portuguese National Health Service (SNS) during the first phase of the pandemic and to identify factors that influence the experience of the teleconsultation. MATERIAL AND METHODS: A cross-sectional analytical study was conducted based on an online survey, between July-September 2020, aimed at SNS doctors. Data on demographics, practice, attitudes and perceptions associated with the teleconsultation was collected. The adjusted prevalence ratio (aPR) was calculated to identify demographic factors and determinants of teleconsultation associated with satisfaction, use of video calls and greater motivation to carry out teleconsultations in the future. RESULTS: 2225 valid responses were obtained. Teleconsultation was carried out by 93.8% of participants in this period, 99.0% used the telephone as a form of communication and only 8.0% used a video call. A high degree of satisfaction with the teleconsultation was significantly associated with perceiving the teleconsultation as providing care with equivalent quality to a face-to-face consultation (aPR = 1.472) and being motivated to do teleconsultation after the pandemic (aPR = 4.081). Reporting clinical (aPR = 0.763) or technical difficulties (aPR = 0.666) was negatively associated with satisfaction). 70.4% of doctors would like to continue doing follow-up teleconsultations and 53.3% consider that video call technologies should always or often be used during teleconsultations. CONCLUSION: Teleconsultation seems to have potential to to become a common practice in the future. However, it is important to address clinical, technical, organizational, and legal questions and, above all, to ensure that it is a safe and valuable practice for patients.

[Intercontinental Multidisciplinary Oncology Videoconferencing between the South Pacific and the French mainland: Results after one year and 323 cases of rare or complex cancers discussed]. / RCP Pacifique : bilan après un an et 323 cancers rares et/ou complexes discutés.

INTRODUCTION: Overseas France represents 18 % of French territory and is home to 4 % of its population for whom there is unequal treatment in the field of rare/complex cancer. AIM: To report our experience of intercontinental multidisciplinary videoconferencing between the French mainland and Pacific territories. METHODS: Every other friday, three centers located in Papeete, Nouméa and Paris-Villejuif connected between 6:30 AM and 8:00 AM GMT to discuss cases of rare/complex cancers. RESULTS: Between November 2019 and December 2020, 323 presentations implicating 233 patients involved sarcoma (n=93), digestive pathology (n=60), neuroendocrine tumors (n=35), urology (n=24), gynecology (n=24), neurology (n=16), thyroid pathology (n=14), dermatology (n=14), senology (n=11), hematology (n=11), ENT pathology (n=10), pathology thoracic (n=10) and pediatrics (n=1). Of the 233 patients, 134 (57.5 %) living in New Caledonia and 99 (42.5 %) in French Polynesia, 117 (50.5 %) had metastatic disease. 39 patients (16.7 %) were transferred to French mainland (EVASAN), for surgery (n=25), vectorized radiotherapy (n=7), biopsy (n=5), chemotherapy (n=1) or inclusion in a clinical trial (n=1). 195 patients (83.7 %) were treated at home, 15 (6.4 %) are still awaiting a decision and 4 (1.7 %) lost to follow-up. CONCLUSION: The use of videoconferencing to discuss rare/complex cancer cases was effective in guaranteeing French overseas population access to innovative therapies and clinical trials, limiting the need for intercontinental transfer to 16.7 %.

Local treatment of pancreatic cancer metastases: A multicenter French study of the AGEO group.

OBJECTIVE: This study reports the efficacy and safety of local treatment of metastases of pancreatic ductal adenocarcinoma (PDAC), with a curative intent. METHODS: We retrospectively included patients with histologically proven PDAC, who underwent a local treatment for metastases between January 1, 2000 and December 31, 2017, from 11 French hospitals. Complications of local treatment were reported. Univariate Cox models were performed to identify prognosis factors associated with overall survival (OS) and disease-free survival (DFS). RESULTS: We included 52 patients treated for 68 metastases; 33 (64%) of whom had metachronous metastases. Metastatic sites treated were: 39 (57%) hepatic, 18 (27%) pulmonary and 11 (16%) others. Metastases treatments were: 45 (66%) surgery, 9 (13%) radiofrequency and 14 (21%) other procedures. The rates of severe complications and mortality were respectively 10% and 4%. The median OS and DFS after local treatment were 36.5 months and 12.7 months, respectively. Prognosis factors associated with a shorter OS were: liver metastases when compared with lung metastases (HR 4.04; 95%CI: 1.18-13.81), N2 status of primary pancreatic tumor when compared to N0-N1 (HR 9.43; 95%CI: 2.44-36.36) and synchronous metastases when compared to metachronous metastases (HR 2.34; 95%CI: 1.05-5.23). N2 status of primary pancreatic tumor was associated with a shorter DFS when compared to N0-N1 (HR 2.82; 95%CI: 1.05-7.58). CONCLUSION: In this series of highly selected patients, local treatment of metastases from PDAC is associated with prolonged survival. The rate of severe complications was low. Factors associated with shorter OS were liver metastases, N2 status and synchronous metastases.

Intercontinental Multidisciplinary Oncology Videoconferencing for Rare and Complex Cancer: An Alternative to Systematic Transfer.

PURPOSE: To report our experience of intercontinental multidisciplinary oncology videoconferencing between the French mainland and South Pacific to discuss rare and/or complex cancer cases. METHODS: On the first and third Friday of each month, all participants connected between 6:30 am and 8:00 am GMT to discuss using a web conference service. RESULTS: Between November 2019 and April 2020, 99 cases concerning 78 patients were discussed. Oncology subspecialties required were sarcoma (n = 36), digestive (n = 29), dermatology (n = 5), gynecology (n = 5), breast (n = 5), urology (n = 5), hematology (n = 5), ENT (n = 3), thoracic (n = 3), thyroid (n = 2), and pediatric (n = 1). Median patient age was 58 years, 41 were female (53%), 37 were male (47%), and 43 had a metastatic disease (55%). Following discussion, 16 patients (21%) were transferred to the French mainland. Reasons for transfer were requirement for complex surgery (n = 11) and need for specialized diagnostic biopsy (n = 5). Fifty-six patients were treated locally, with systemic chemotherapy (n = 36), surveillance (n = 8), surgery (n = 8), radiotherapy (n = 3), or endoscopy (n = 1). Direct benefits for patients treated in their local facility included strategy changes (surveillance or surgery contraindication, n = 9), targeted therapy decision (n = 14), immunotherapy decision (n = 9), and diagnostic or metastatic status corrections (n = 4). Six patients are still awaiting decision. CONCLUSION: Using real-time intercontinental multidisciplinary oncology videoconferencing to discuss complex or rare cancer cases is reliable and effective for decision making. This concept helped to limit to 21% the need for transfers to the mainland.

Neutrophil-to-Lymphocyte Ratio Predicts Cerebral Edema and Clinical Worsening Early After Reperfusion Therapy in Stroke.

BACKGROUND AND PURPOSE: The mechanisms linking systemic inflammation to poor outcome in ischemic stroke are not fully understood. The authors investigated if peripheral inflammation following reperfusion therapy leads to an increase in cerebral edema (CED), thus hindering the clinical recovery. METHODS: We designed a single-center study conducted at Centro Hospitalar Universitário São João between 2017 and 2019. Inclusion criteria were being adult, having an anterior circulation acute ischemic stroke, and receiving reperfusion therapy. Neutrophil-to-lymphocyte, platelet-to-lymphocyte ratios, and the systemic inflammatory response syndrome criteria were determined. The presence and grade of CED were evaluated on the computed tomography performed 24 hours following event. The clinical outcomes included early neurological deterioration and functional dependence at 90 days. Adjusted odds ratio and 95% CI were obtained by ordinal and logistic regression models. Optimal cutoff values were defined using receiver operating characteristic analysis in the training cohort and validated in an independent data set. RESULTS: Five hundred fifty-three patients were included. Neutrophil-to-lymphocyte increased with higher degrees of CED at 24 hours (adjusted odds ratio, 1.34 [1.09-1.68], P<0.01) and was associated with early neurological deterioration (adjusted odds ratio, 1.30 [1.04-1.63], P<0.05) and poor functional status at 90 days (adjusted odds ratio, 1.79 [1.28-2.48], P<0.01). Platelet-to-lymphocyte was not associated with the outcomes. Systemic inflammatory response syndrome was related to CED due to altered white blood cell counts. Neutrophil-to-lymphocyte was the best predictor with an area under the curve around 0.7. Neutrophil-to-lymphocyte ≥7 had and accuracy, sensitivity, and specificity around 60%. CONCLUSIONS: Increased systemic inflammation is linked to the severity of CED early after reperfusion therapy in stroke. Easily obtained inflammatory markers convey early warning alerts for patients at risk of severe neurological complications with an impact on long-term functional outcome. CED quantification should be included as an end point in proof-of-concept trials in immunomodulation in stroke.

QualFatigue study: which factors influence the use of specific interventions for breast cancer survivors with fatigue? A cross-sectional exploratory study.

PURPOSE: International guidelines recommend specific interventions to reduce cancer-related fatigue (CRF). Evidence suggests underutilization of these interventions among breast cancer survivors. The QualFatigue study aimed to explore the potential factors influencing the use of specific interventions, for relief, in patients with CRF through qualitative analyses. METHODS: Patients with stage I-III breast cancer, and CRF ≥4 on a 10-point numerical scale were recruited within 6-24 months at the end of their primary treatment. Semi-structured interviews were performed. Emergent themes were identified using a stepped content analysis (QDA Miner software). RESULTS: Data saturation was achieved with 15 interviews. Four main themes emerged as potential sources of influence in the participants' use of specific interventions: (1) expectations regarding the management of CRF, (2) representations of the benefits provided by the interventions, (3) individual physical and psychological conditions, and (4) social and environmental situations. Six key levers came out transversally to optimize the use of specific interventions to relieve CRF: (1) listening and recognition of the individual difficulties and needs; (2) individual and global health assessments; (3) information and advice on how to manage CRF; (4) discussion groups focused on the management of CRF; (5) group activities; and (6) professional and personalized guidance. CONCLUSION: This study calls for multi-level action to address many persistent barriers and exploit levers in the management of CRF.

A qualitative evaluation of the use of interventions to treat fatigue among cancer survivors: A healthcare provider's view.

OBJECTIVE: Cancer-related fatigue (CRF) is among the most common and distressing side effects of cancer treatment. Different types of interventions, including physical activity (PA), psychosocial and mind-body interventions, have been shown to reduce CRF. We aimed to explore HCPs' practices and barriers to refer patients towards interventions to reduce CRF. METHODS: We performed a qualitative study using key informant interviews among a sample of 20 HCPs including medical, surgical and radiation oncologists, pain specialists, nurses, psychologists, psychiatrists and physiotherapists recruited from breast, prostate and colorectal cancer disease groups from a comprehensive cancer centre. RESULTS: Most interviewees reported not to address CRF spontaneously during consultations. When the topic of CRF was brought up by patients, all interviewees acknowledged to recommend PA, whereas few would recommend psychosocial or mind-body interventions. Barriers to recommend interventions to manage CRF included: lack of knowledge about CRF and its treatment, lack of time and complexity of the referral due to their accessibility and cost. CONCLUSION: In a diverse sample of HCPs, most acknowledged not to address CRF proactively with their patients, but identified several actionable barriers. Specific training on screening and management of CRF and improving the referral network dedicated to interventions need to be implemented.

Changes in weight, physical and psychosocial patient-reported outcomes among obese women receiving treatment for early-stage breast cancer: A nationwide clinical study.

BACKGROUND: Evidence on how weight loss correlates to health-related quality-of-life (HRQOL) among obese breast cancer (BC) patients is limited. We aimed to evaluate associations between weight changes and HRQOL. METHODS: We included 993 obese women with stage I-II-III BC from CANTO, a multicenter, prospective cohort collecting longitudinal, objectively-assessed anthropometric measures and HRQOL data (NCT01993498). Associations between weight changes (±5% between diagnosis and post-treatment [shortly after completion of surgery, adjuvant chemo- or radiation-therapy]) and patient-reported HRQOL (EORTC QLQ-C30/B23) were comprehensively evaluated. Changes in HRQOL and odds of severely impaired HRQOL were assessed using multivariable generalized estimating equations and logistic regression, respectively. RESULTS: 14.1% women gained weight, 67.3% remained stable and 18.6% lost weight. Significant decreases in functional status and exacerbation of symptoms were observed overall post-treatment. Compared to gaining weight or remaining stable, obese women who lost weight experienced less of a decline in HRQOL, reporting better physical function (mean change [95%CI] for gain, stability and loss: -12.9 [-16.5,-9.3], -6.9 [-8.2,-5.5] and -6.2 [-8.7,-3.7]; pinteraction[weight-change-by-time] = 0.006), less dyspnea (+18.9 [+12.3,+25.6], +9.2 [+6.5,+11.9] and +3.2 [-1.0,+7.3]; pinteraction = 0.0003), and fewer breast symptoms (+22.1 [+16.8,+27.3], +18.0 [+15.7,+20.3] and +13.4 [+9.0,+17.2]; pinteraction = 0.044). Weight loss was also significantly associated with reduced odds of severe pain compared with weight gain (OR [95%CI] = 0.51 [0.31-0.86], p = 0.011) or stability (OR [95%CI] = 0.62 [0.41-0.95], p = 0.029). No associations between weight loss and worsening of other physical or psychosocial parameters were found. CONCLUSIONS: This large contemporary study suggests that weight loss among obese BC patients during early survivorship was associated with better patient-reported outcomes, without evidence of worsened functionality or symptomatology in any domain of HRQOL.

Fatigue and physical activity in cancer survivors: A cross-sectional population-based study.

PURPOSE: A substantial proportion of cancer survivors experience fatigue after diagnosis. Physical activity (PA) can impact fatigue after cancer. In this study, we evaluated the prevalence and association of fatigue and the practice of PA in a population with early cancer. METHODS: Using the national population-based French cross-sectional study Vie après le cancer 2, we included 1984 patients with early breast (61.1%), prostate (21.5%), and colorectal (17.4%) cancer. Severe fatigue at 2 years postdiagnosis was defined by a score ≥40 in the European Organization for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ C30) fatigue subscale. PA was defined as (a) self-reported PA before diagnosis (active/inactive) and (b) change in PA since diagnosis (increased/maintained exposure vs decreased exposure/remaining inactive). Multivariate regression examined associations of severe fatigue with PA, adjusting for baseline clinical and treatment variables. RESULTS: Median age was 52 years. 51.5% of patients experienced severe fatigue 2 years post-diagnosis. 87.7% reported to be physically active before cancer diagnosis; 53.3% of patients either decreased PA or remained inactive at 2 years postdiagnosis. At 2 years postdiagnosis, severe fatigue was associated with a change in PA since diagnosis: patients with decreasing PA/remaining inactive from pre- to postdiagnosis had a higher risk of severe fatigue vs those with increasing/maintaining PA (adjusted odds ratio [95% confidence interval] 2.32 [1.85-2.90]). CONCLUSION: Fatigue continues to be a substantial problem for cancer survivors 2 years after cancer diagnosis and is associated with PA decreasing/remaining inactive since diagnosis. Interventions to maintain or increase PA for cancer survivors should be tested to mitigate long-term fatigue after cancer.

High incidence of cetuximab-related infusion reactions in head and neck patients.

BACKGROUND: Cetuximab is crucial in the management of squamous cell carcinoma of the head and neck of patients. Grade 3-4 cetuximab-induced infusion reactions (CI-IRs) occur in 2% of patients with colorectal cancer. Despite the 2.7% CI-IR rate in the EXTREME trial, higher rates were reported in small series of patients with head and neck squamous cell carcinoma (HNSCC) (6%-18%). There is an urgent need to better appraise the natural history and the predictive factors for CI-IRs in patients with HNSCC exposed to cetuximab. METHODS: The medical records from patients with HNSCC (n=428) treated by cetuximab at Gustave Roussy from January 2013 to December 2015 were reviewed. The impact of potential risk factors was analysed. RESULTS: Out of 428 patients, 24 patients (5.4%) presented CI-IR, including grade 3-4 (95.7%); about 21% (5/24) requiring intensive care unit referral and quasi all occurred within the first cycle (21/24). In a multivariate analysis, the occurrence of grade 3-4 CI-IR was associated with tobacco and alcohol history (p=8.5e-3) and with prior allergy history (p=2.9e-3). CI-IRs tended to be associated with poor overall survival in patients with recurrent and metastatic HNSCC and with a higher number of further lines of chemotherapy. CONCLUSION: In real life, CI-IRs appear far more common in patients with HNSCC (5.4%) than reported in prospective trials. This is the largest series of patients ever focusing on the risk of CI-IR in patients with HNSCC. Prior allergy history and tobacco history are associated with CI-IR and could be used to better allocate treatment. Further prospective data are required to confirm these findings.

In the immuno-oncology era, is anti-PD-1 or anti-PD-L1 immunotherapy modifying the sensitivity to conventional cancer therapies?

INTRODUCTION: The advent of anti-programmed death receptor-1/ligand-1 antibodies (anti-PD(L)1) is profoundly changing the therapeutic strategy of oncology. As anti-PD(L)1 modulate tumour microenvironment, it might impact sensitivity to conventional cancer therapy (CCT). Therefore, we explored whether sensitivity to CCT was different before and after anti-PD(L)1 therapy. METHODS: Patients who started anti-PD(L)1 treatment at Gustave Roussy Cancer Centre between February 2012 and December 2015, and who received at least one line of CCT immediately before and immediately after anti-PD(L)1, were eligible. We analysed progression-free survival (PFS) and overall response rate (ORR) of the CCT line immediately before (PFSpre/ORRpre) and after (PFSpost/ORRpost) anti-PD(L)1. PFS and ORR were compared using Wilcoxon signed rank and McNemar tests in a paired data subset for patients having received identical class of CCT pre and post anti-PD(L)1 therapy. RESULTS: Among 118 eligible patients, 65% received anti-PD1 and 35% anti-PD-L1 agents. Median PFSpre versus PFSpost was 4.7 versus 3.5 months (p = 0.011), respectively; it was 5.7 versus 6.8 months (NS) for patients who derived clinical benefit from immunotherapy and 3.9 versus 3.0 months (p = 0.012) for patients who were primary resistant to anti-PD(L)1 therapy. Subgroup analysis did not reveal any significant difference in PFS or ORR before versus after anti-PD(L)1 therapy according to CCT class or to its ability to induce immunogenic cell death. CONCLUSION: Patients who derive benefit from immune therapies tend to have better PFS on conventional therapies after having received the anti-PD(L)1 agent. Further studies on larger data sets are warranted to confirm these findings.

Real world prospective experience of axitinib in metastatic renal cell carcinoma in a large comprehensive cancer centre.

BACKGROUND: Axitinib has shown activity in metastatic renal cell carcinoma (mRCC) in a large phase III clinical trial and was approved in patients who failed first-line therapy. This drug has been available in France since November 2012. The objective is to report efficacy and safety of axitinib in mRCC outside of clinical trials. METHODS: A prospective evaluation of mRCC patients treated by axitinib in second or further next-line therapy at Gustave Roussy was conducted from 2012 to 2015. Objective response rate (ORR), progression-free survival (PFS), time to treatment failure (TTF), overall survival (OS) and toxicities were analysed. The correlation between clinical markers and ORR, PFS, TTF and OS were explored. RESULTS: One-hundred and sixty patients with mRCC, received axitinib in second (40%) or further next-line therapy (60%). International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk group classification was good, intermediate and poor in 13%, 54% and 32%, respectively. Dose titration (DT) to 7 mg twice a day (bid) was performed in 38% and to 10 mg bid in 19% of the patients. Hypertension was the most common adverse event, (grade (G)3: 39%; G4: 2%). ORR occurred in 32% (n = 33, only partial response). Median PFS, TTF and OS were 8.3, 5.8 and 16.4 months, respectively. IMDC risk group and DT at 2 weeks are associated to ORR while grade 3 hypertension is marginally associated. IMDC risk group and grade 3 hypertension are significantly associated with better PFS, TTF and OS while DT at 2 weeks is associated to PFS and TTF. CONCLUSION: Efficacy of axitinib in routine practice is similar to that previously reported, not only in second- but also in further next-lines of therapy.

Haemoglobin level increase as an efficacy biomarker during axitinib treatment for metastatic renal cell carcinoma: a retrospective study.

BACKGROUND: Axitinib is used after failure of first line treatment for metastatic renal cell carcinoma (mRCC). A known side effect is the increase of haemoglobin level (HbL) during treatment with a suspected correlation with better outcome. Our objective was to examine whether HbL increase during the first three months of axitinib treatment is associated with better prognosis. METHODS: Retrospective multicentre analysis including patients with mRCC treated with axitinib for at least three months from 2012 to 2014. Progression-free survival (PFS) was analysed by a Cox model according to gender, International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) prognostic score, high blood pressure (hBP), and maximum increase in HbL within the first three months of treatment. RESULTS: Ninety-eight patients were analysed (71% men; median age at treatment initiation: 62 years; IMDC: 24%, 50%, and 26% in the favourable, intermediate, and poor-risk group, respectively). Patients received axitinib for a median of 8 months. During the first three months, the median increase of HbL was +2.3 g/dL (-1.1; 7.2). Fifty-six (57%) patients developed hBP. In multivariate analysis, after adjustment for performance status (P < 0.0001) and gender (P = 0.0041), the combination of HbL increase ≥2.3 g/dL and any grade hBP was significantly associated with longer PFS (HR = 0.40, 95%CI [0.24; 0.68]). CONCLUSIONS: Early HbL increase during axitinib treatment combined with hBP is an independent predictive factor of PFS. These results require validation in a prospective setting.

Outcomes following laryngectomy refusal after insufficient response to induction chemotherapy.

OBJECTIVE: To review patients who refused a total laryngectomy and were treated with radiotherapy (RT) after insufficient response to induction chemotherapy in a larynx preservation protocol for advanced-stage cancer of the larynx and to compare their outcomes with good responders. STUDY DESIGN: Retrospective cohort study. METHODS: Eighty-six patients treated with induction chemotherapy followed by RT were included in the analysis: 75 good responders and 11 insufficient responders who refused surgery. We compared overall survival (OS), disease-free survival (DFS), and laryngo-esophageal dysfunction-free survival (LEDFS) of the cohort populations in univariate and multivariate analyses. RESULTS: The median follow-up was 44 months. The 2-year and 5-year survival rates were respectively 72.2% and 58.8% for OS, 62.8% and 49.4% for DFS, and 59.5% and 44.3% for LEDFS. No survival endpoint was significantly decreased among insufficient responders, contrary to what we expected. When we focused on patients with an initially fixed larynx, the recovery of larynx mobility after induction chemotherapy was not associated with OS (P = 0.6055), DFS (P = 0.459), or LEDFS (P = 0.7403). CONCLUSION: To the best of our knowledge, our study is the first patient treatment evaluation focused on subjects who refused a total laryngectomy after insufficient response to induction chemotherapy in a larynx preservation protocol for advanced-stage cancer of the larynx. Surprisingly, these patients treated with RT in our cancer center did not experience decreased functional and oncologic outcomes compared to good responders. Further studies will explore the relevance of response criteria and their evaluation methods. LEVEL OF EVIDENCE: 4. Laryngoscope, 127:1791-1796, 2017.

Laryngo-esophageal Dysfunction-free Survival in a Preservation Protocol for T3 Laryngeal Squamous-cell Carcinoma.

BACKGROUND: We reviewed the outcomes of patients with T3 laryngeal neoplasms with a fixed hemilarynx, a large gross tumor volume or a subglottic extension (SGE), treated with a laryngeal-preservation protocol with induction chemotherapy. PATIENTS AND METHODS: The study end-points were laryngo-esophageal dysfunction-free survival (LEDFS), laryngectomy-free survival (LFS), overall survival (OS), and disease-free survival (DFS). RESULTS: A total of 104 patients were included. The 2-year and 5-year OS rates were 70.4% and 54.5%, respectively. OS and DFS were independent of the treatment modality in the whole cohort (p=0.6546 and p=0.3006, respectively) and in patients with SGE (p=0.529 and p=0.255, respectively). The 2-year and 5-year LEDFS rates were 44.3% and 28.2%, respectively. LEDFS was not associated with initial hemilaryngeal fixation or SGE (p=0.5772 and p=0.0623, respectively). CONCLUSION: Chemoselection is feasible without compromised oncological or functional outcomes in patients with an initially fixed hemilarynx or subglottic extension.

N-Telopeptide of Type I Collagen Long-Term Dynamics in Breast Cancer Patients With Bone Metastases: Clinical Outcomes and Influence of Extraskeletal Metastases.

BACKGROUND: Markers of bone metabolism, such as N-telopeptide of type I collagen (NTX), have been demonstrated to be prognostic in previous trials of breast cancer (BC) patients with bone metastases (BMs). In the present study, we tested the survival effect of the NTX response to zoledronic acid (ZA) at 3 and 12 months in a contemporaneous cohort of BC patients with BMs and evaluated the influence of extraskeletal metastatic disease on NTX variation. PATIENTS AND METHODS: The present study was a prospective cohort study of consecutive BC patients diagnosed and treated at a single center. Patients presenting with de novo radiological evidence of BMs who started monthly intravenous ZA were included. Urinary NTX was measured at baseline and 1, 3, 6, 9, and 12 months after ZA introduction. RESULTS: Overall, 71 patients were enrolled, 32 with BMs and 39 with BMs plus extraskeletal metastases. The proportion of patients with elevated NTX at baseline and 3 and 12 months was 49.3%, 26.6%, and 34.2%, respectively. The variables associated with survival included age at diagnosis, tumor estrogen receptor status, and NTX at 3 and 12 months. Multivariate analysis showed that, in addition to age at diagnosis, only the 3-month NTX level was significantly associated with survival. Patients with BMs plus extraskeletal metastases had an erratic NTX variation pattern, unrelated to survival. CONCLUSION: In the present contemporaneous cohort of BC patients with BMs, the NTX response at 3 months was strongly associated with survival. Furthermore, an early response to ZA was strongly associated with long-term NTX control. Finally, patients with BMs plus extraskeletal metastases had an erratic NTX variation. IMPLICATIONS FOR PRACTICE: The present study showed that when accommodating recent therapy innovations and longer patient survival, the N-telopeptide (NTX) variation at 3 months is strongly associated with survival. In this setting, in addition to a few other clinicopathological features, NTX is a powerful prognostic marker. Moreover, early NTX correction associates with persistently normal NTX. This might identify a subgroup of patients with a good prognosis who are eligible for premature zoledronic acid (ZA) de-escalation. Finally, patients with bone plus extraskeletal metastases showed an erratic variation of NTX, raising concerns that a single ZA regimen might not fit all patients. Future trials should test its effect according to the presence of extraskeletal involvement.
