Regorafenib in patients with advanced Ewing sarcoma: results of a non-comparative, randomised, double-blind, placebo-controlled, multicentre Phase II study.

BACKGROUND: The REGOBONE multi-cohort study explored the efficacy and safety of regorafenib for patients with advanced bone sarcomas; this report details the Ewing sarcoma (ES) cohort. METHODS: Patients with relapsed ES progressing despite prior standard therapy, were randomised (2:1) to receive regorafenib or placebo. Patients on placebo could crossover to receive regorafenib after centrally confirmed progression. The primary endpoint was the progression-free rate at 8 weeks. With one-sided α of 0.05, and 80% power, at least 14/24 progression-free patients at 8 weeks were needed for success. RESULTS: From September 2014 to November 2019, 41 patients were accrued. 36 patients were evaluable for efficacy: 23 on regorafenib and 13 on placebo. Thirteen patients (56%; one-sided 95% CI [37.5%-[)) were progression-free at 8 weeks on regorafenib vs. 1 (7.7%; 95% CI [0.4%-[) on placebo. Median PFS was 11.4 weeks on regorafenib, and 3.9 weeks on placebo. Ten placebo patients crossed over to receive regorafenib after progression. The most common grade ≥3 regorafenib-related adverse events were pain (22%), asthenia (17%), thrombocytopenia (13%) and diarrhoea (13%). CONCLUSION: Although the primary endpoint was not met statistically in this randomised cohort, there is evidence to suggest that regorafenib might modestly delay tumour progression in relapsed ES after failure of prior chemotherapy.

Treatment of 120 adult osteosarcoma patients with metachronous and synchronous metastases: A retrospective series of the French Sarcoma Group.

Treatment options for metastatic osteosarcomas are scarce. Following failure of standard first line therapy, patients who relapse present a challenging treatment dilemma, and have a poor prognosis. Surgical removal of all metastases is essential. A retrospective analysis of patients with metastatic osteosarcomas was conducted in 15 French Sarcoma Group centers. From January 2009 to December 2018, we identified 120 adult patients; 36 with synchronous and 84 with metachronous metastases with 74 males and 46 females. Mean age was 30 years (18-53). Metastatic sites were lung, bone and other in 91, 11 and 24 patients, respectively. Mean time to first metachronous metastases was 22 months (4-97). All patients except 13 (10.8%) with metachronous metastases received a first line systemic treatment for relapse, and 39 patients (32.5%) were included in a clinical trial. Eighty-one patients (67.5%) had local treatment of distant metastases. Median progression free survival (PFS) and overall survival (OS) were 5.5 (95% CI 4.6-6.4) and 20.5 months (95% CI 13.2-27.7) respectively for the overall group. In multivariate analysis, more than five metastases, time to first metastases <24 months, were statistically significant negative prognostic factors for OS and PFS (P = .002, ≤.001 and P = .006, ≤.001, respectively). Surgery of metastases was associated with better prognosis on OS and PFS (P = .001 and .037, respectively). The presence of bone metastases was a negative prognostic factor on OS but not on PFS (P = .021). In reference sarcoma centers, relapsed osteosarcoma patients with more than one metastasis commonly receive more than one line of systemic therapy, and are included in clinical trial if available.

Impact of adjuvant trastuzumab treatment on fatigue, emotional status and quality of personal and work life of patients with localised breast cancer: results of the 'HER-ception' study.

PURPOSE: The aim of this study was to analyse the impact of adjuvant trastuzumab on fatigue, emotional status, and quality of personal and work life of patients treated for localised breast cancer. METHODS: In a prospective setting, we recruited age-matched localised breast cancer patients, treated by adjuvant chemotherapy with (group 1) or without IV trastuzumab (group 2), between September 2011 and May 2014. Patients completed questionnaires on quality of life (FACT-G, FACT-B), fatigue (FACIT-F, ICQ), anxiety-depression (HADS), and work life (dedicated self-questionnaire) at inclusion then at 3, 6, 9, and 15 months. RESULTS: We included 35 patients in each group. No significant difference was found between the two groups concerning return to work, fatigue, and quality of life scores at each phase of the study. In total, 39 patients (72.2%) reported having returned to work at T15, with no significant difference between the two groups (p = 0.53). Significantly higher scores for'helplessness' outcomes were observed in group 1, 9, and 15 months (6.138 and 5.731; p = 0.047 and 0.048, respectively). Patients in group 1 reported higher score of anxiety-depression than group 2 at 3 months (p = 0.027) then no significant difference was observed at the other times of the study. CONCLUSION: Trastuzumab does not appear to affect fatigue and return to work in patients with localised breast cancer. The emotional well-being could be affected in patients treated by trastuzumab, with a more pronounced 'helplessness' feeling which could be more related to the additional follow-up imposed by the prescription of trastuzumab.

Cognitive rehabilitation program to improve cognition of cancer patients treated with chemotherapy: A 3-arm randomized trial.

BACKGROUND: There is no treatment for cancer-related cognitive impairment, an important adverse effect that negatively impacts quality of life (QOL). We conducted a 3-arm randomized controlled trial to evaluate the impact of computer-assisted cognitive rehabilitation (CR) on cognition, QOL, anxiety, and depression among cancer patients treated with chemotherapy. METHODS: Patients who reported cognitive complaints during or after completing chemotherapy were randomly assigned to 1 of 3 12-week CR programs: computer-assisted CR with a neuropsychologist (experimental group A), home cognitive self-exercises (active control group B), or phone follow-up (active control group C). Subjective cognition was assessed by the Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog), objective cognition was assessed by neuropsychological tests, QOL was assessed by the FACT-General, and depression and anxiety were assessed by psychological tests. The primary endpoint was the proportion of patients with a 7-point improvement in the FACT-Cog perceived cognitive impairment (PCI) score. RESULTS: Among the 167 enrolled patients (median age, 51 years), group A had the highest proportion of patients with a 7-point PCI improvement (75%), followed by groups B (59%) and C (57%), but the difference was not statistically significant (P = .13). Compared with groups B and C, the mean difference in PCI score was significantly higher in group A (P = .02), with better perceived cognitive abilities (P < .01) and a significant improvement in working memory (P = .03). Group A reported higher QOL related to cognition (FACT-Cog QOL) (P = .01) and improvement in depression symptoms (P = .03). CONCLUSIONS: These results suggest a benefit of a computer-based CR program in the management of cancer-related cognitive impairment and complaints.

Efficacy and safety of regorafenib in adult patients with metastatic osteosarcoma: a non-comparative, randomised, double-blind, placebo-controlled, phase 2 study.

BACKGROUND: Regorafenib has proven activity in patients with pretreated gastrointestinal stromal tumours and colorectal and hepatocellular carcinoma. We designed REGOBONE to assess the efficacy and safety of regorafenib for patients with progressive metastatic osteosarcoma and other bone sarcomas. This trial comprised four parallel independent cohorts: osteosarcoma, Ewing sarcoma, chondrosarcoma, and chordoma. In this Article, we report the results of the osteosarcoma cohort. METHODS: In this non-comparative, double-blind, placebo-controlled, phase 2 trial, patients aged 10 years or older with histologically confirmed osteosarcoma whose disease had progressed after treatment with one to two previous lines of chemotherapy for metastatic disease and an Eastern Cooperative Oncology Group performance status of 0 or 1 were enrolled. Patients were randomly assigned (2:1) to receive either oral regorafenib (160 mg/day, for 21 of 28 days) or matching placebo. Patients in both groups also received best supportive care. Randomisation was done using a web-based system and was stratified (permuted block) by age at inclusion (<18 vs ≥18 years old). Investigators and patients were masked to treatment allocation. Patients in the placebo group, after centrally confirmed progressive disease, could cross over to receive regorafenib. The primary endpoint was the proportion of patients without disease progression at 8 weeks. Analyses were done by modified intention to treat (ie, patients without any major entry criteria violation who initiated masked study drug treatment were included). All participants who received at least one dose of study drug were included in the safety analyses. This study is registered with ClinicalTrials.gov, number NCT02389244, and the results presented here are the final analysis of the osteosarcoma cohort (others cohorts are ongoing). FINDINGS: Between Oct 10, 2014, and April 4, 2017, 43 adult patients were enrolled from 13 French comprehensive cancer centres. All patients received at least one dose of assigned treatment and were evaluable for safety; five patients were excluded for major protocol violations (two in the placebo group and three in the regorafenib group), leaving 38 patients who were evaluable for efficacy (12 in the placebo group and 26 in the regorafenib group). 17 of 26 patients (65%; one-sided 95% CI 47%) in the regorafenib group were non-progressive at 8 weeks compared with no patients in the placebo group. Ten patients in the placebo group crossed over to receive open-label regorafenib after centrally confirmed disease progression. 13 treatment-related serious adverse events occurred in seven (24%) of 29 patients in the regorafenib group versus none of 14 patients in the placebo group. The most common grade 3 or worse treatment-related adverse events during the double-blind period of treatment included hypertension (in seven [24%] of 29 patients in the regorafenib group vs none in the placebo group), hand-foot skin reaction (three [10%] vs none), fatigue (three [10%] vs one [3%]), hypophosphataemia (three [10%] vs none), and chest pain (three [10%] vs none). No treatment-related deaths occurred. INTERPRETATION: Regorafenib demonstrated clinically meaningful antitumour activity in adult patients with recurrent, progressive, metastatic osteosarcoma after failure of conventional chemotherapy, with a positive effect on delaying disease progression. Regorafenib should be further evaluated in the setting of advanced disease as well as potentially earlier in the disease course for patients at high risk of relapse. Regorafenib might have an important therapeutic role as an agent complementary to standard cytotoxic chemotherapy in the therapeutic armamentarium against osteosarcoma. FUNDING: Bayer HealthCare.

Optimisation of chemotherapy prescription and preparation in an ambulatory unit: Validation of the OPTIMA program.

OBJECTIVE: We implemented the two-step OPTIMA program to anticipate chemotherapy prescription which aims to assess the discrepancy rate between anticipated and real prescription and its impact on waiting time and quality of care. METHODS: This prospective study included cancer patients receiving any intravenous chemotherapy. The OPTIMA program consists in a nurse phone call and a blood sample two days before the planned treatment. Collected information and biological results were used by a physician to issue a non-effective (step 1) or effective (step 2) anticipated prescription the day before the consultation. The real prescription was given as usual by another physician on the day of the consultation. Waiting time was collected, and patients' satisfaction with care was assessed with the OUT-PATSAT35 questionnaire. RESULTS: Respectively, 540 and 979 consultations (283 and 294 patients) were analysed in both steps. The discrepancy rate was 8.7% (step 1). In routine practice, the OPTIMA program (step 2) reduced patients' waiting time (median time 55 vs. 95 min, p < 0.001). A high general care satisfaction score was observed in both steps (80.7% and 80.2%). CONCLUSIONS: This anticipation program demonstrated the accuracy of chemotherapy prescription, whatever the regimen and cancer site, and its impact on waiting time optimisation.

Safety and efficacy of regorafenib in patients with advanced soft tissue sarcoma (REGOSARC): a randomised, double-blind, placebo-controlled, phase 2 trial.

BACKGROUND: Regorafenib is a multikinase inhibitor with proven activity in refractory gastrointestinal stromal tumours and chemotherapy-refractory advanced colorectal cancers. We assessed this agent's efficacy and safety in patients with metastatic soft tissue sarcomas previously treated with anthracycline. METHODS: In this randomised, double-blind, phase 2 trial undertaken in France and Austria, we enrolled patients aged 18 years and older with advanced soft tissue sarcomas who had received previous doxorubicin or other anthracycline treatment. These patients were randomly assigned (1:1) into one of the following four cohorts: liposarcoma, leiomyosarcoma, synovial sarcoma, and other sarcomas. Participants were treated with oral regorafenib (160 mg per day 3 weeks on and 1 week off) or matched placebo. Patients receiving placebo were offered optional crossover in case of centrally confirmed disease progression. The random allocation schedule was computer-generated with permuted blocks of four patients, with two stratification factors: country (France or Austria) and previous exposure to pazopanib (yes or no). Eligibility criteria included patients with histologically proven advanced and inoperable soft tissue sarcomas with intolerance or failure to doxorubicin or other anthracycline-based chemotherapy and at least one unidimensionally or bidimensionally measurable lesion according to Response Evaluation Criteria in Solid Tumors (RECIST; version 1.1). The primary endpoint was RECIST-based progression-free survival after central radiological review in the intention-to-treat population. Patients, physicians, and radiologists of the panel were masked to treatment allocation. This study is still open for recruitment for an additional stratum (patients previously treated with pazopanib) and registered with ClinicalTrials.gov, NCT01900743. FINDINGS: From Aug 5, 2013, to Nov 26, 2014, 182 patients were randomly assigned to one of four cohorts and included in the final analysis. At the cutoff date (Jan 7, 2016), the number of required events was reached for the four cohorts. In the liposarcoma cohort, progression-free survival was 1·1 months (95% CI 0·9-2·3) with regorafenib versus 1·7 months (0·9-1·8) with placebo (HR 0·89 [95% CI 0·48-1·64] p=0·70). In the leiomyosarcoma cohort, progression-free survival was 3·7 months (95% CI 2·5-5·0) with regorafenib versus 1·8 (1·0-2·8) months with placebo (HR 0·46 [95% CI 0·46-0·80] p=0·0045). In the synovial sarcoma cohort, progression-free survival was 5·6 months (95% CI 1·4-11·6) with regorafenib versus 1·0 (0·8-1·4) with placebo (HR 0·10 [95% CI 0·03-0·35] p<0·0001). In the other sarcoma cohort, progression-free survival was 2·9 months (95% CI 1·0-7·8) with regorafenib versus 1·0 (0·9-1·9) with placebo (HR 0·46 [95% CI 0·25-0·81] p=0·0061). Before crossover, the most common clinically significant grade 3 or higher adverse events were arterial hypertension (17 [19%] events in the 89 patients in the regorafenib group vs two [2%] events in the 92 patients in the placebo group), hand and foot skin reaction (14 [15%] vs no events) and asthenia (12 [13%] vs six [6%]). One treatment-related death occurred in the regorafenib group due to liver failure. INTERPRETATION: Regorafenib has an important clinical antitumour effect in non-adipocytic soft tissue sarcomas, improving progression-free survival. Regorafenib should be further evaluated in this setting, and its therapeutic role has to be defined in the context of the growing therapeutic armamentarium, already including one approved multikinase inhibitor, pazopanib.

How to improve the prevention of chemotherapy-induced nausea and vomiting? The French NAVI study.

PURPOSE: Chemotherapy-induced nausea and vomiting (CINV) still remain frequent. The procedure for announcing the diagnosis (PAD) was an emblematic measure of the first French Plan Cancer aiming at providing patients with time to listen, information after cancer diagnosis, and discussion on treatments and their side effects. We aimed at assessing the risk factors of CINV, focusing on patients' satisfaction with the PAD. METHODS: This prospective multicentre study assessed the frequency and intensity of CINV among chemonaïve patients during the first cycle of treatment. CINV was defined by ≥1 emetic episode or reported nausea intensity ≥3 on a 0-10 scale. Multivariate analysis was used to identify factors related to global CINV onset including satisfaction with the PAD (satisfaction score ≥the median on a 0-10 scale). RESULTS: Data from 291 patients (women, 85.2%; mean age, 57 years) were analyzed. Most patients (69.4%) received highly emetogenic chemotherapy regimens and 77.7% received antiemetic drugs consistent with international guidelines. Acute, delayed and overall CINV were experienced by 40.4, 34.8 and 52.4% of patients, respectively. Sixty-seven per cent of patients were satisfied with the PAD. No relation was noted between PAD satisfaction and CINV onset. The nausea and vomiting dimension of the QLQ-C30 questionnaire before chemotherapy (OR 3.62), motion sickness history (OR 2.73), highly emetogenic CT (OR 2.73), anxiety (OR 1.99) and younger age (OR 1.96) were independent predictive factors. CONCLUSIONS: Although patients were mostly satisfied with the PAD, half of them experienced CINV. A state of anxiety could be identified during the PAD to be managed.

Trabectedin in combination with doxorubicin for first-line treatment of advanced uterine or soft-tissue leiomyosarcoma (LMS-02): a non-randomised, multicentre, phase 2 trial.

BACKGROUND: Metastatic leiomyosarcomas of uterine or soft-tissue origin have poor prognosis and moderate chemosensitivity. Trabectedin has shown activity in pretreated leiomyosarcoma. We did a single-group, multicentre, phase 2 trial (LMS-02) to assess the effect of first-line doxorubicin and trabectedin combination on disease control and survival. METHODS: Adults (18 years to physiological age ≤70 years) with measurable metastatic or unresectable uterine leiomyosarcoma or soft-tissue leiomyosarcoma who had not received any previous chemotherapy were enrolled at 19 centres in France. Treatment consisted of 60 mg/m(2) intravenous doxorubicin followed by 1·1 mg/m(2) trabectedin in a 3 h intravenous infusion on day 1, both by the central venous route, and 6 mg subcutaneous pegfilgrastim on day 2, repeated every 3 weeks for up to six cycles. Surgery for residual disease was permitted. The primary endpoint was the proportion of patients achieving disease control, defined as complete or partial response or stable disease. Stratification was done by anatomical site and analyses were per protocol. This study is registered with ClinicalTrials.gov, number NCT02131480. FINDINGS: Between July 28, 2010, and May 10, 2013, 109 patients were enrolled and treated, of whom 108 were assessable for response: 47 in the uterine leiomyosarcoma group and 61 in the soft-tissue leiomyosarcoma group. 32 (68%) patients in the uterine leiomyosarcoma group and 45 (74%) in the soft-tissue leiomyosarcoma group received all six cycles of treatment. Of 47 patients with uterine leiomyosarcoma, 28 (59·6%, 95% CI 44·3-73·6) achieved a partial response and 13 (27·7%, 15·6-42·6) stable disease; 41 (87·2%, 74·3-95·2) patients achieved disease control. Of 61 patients with soft-tissue leiomyosarcoma, two (3·3%, 95% CI 0·4-11·7) achieved a complete response, 22 (36·1%, 25·0-50·8) had a partial response, and 32 (52·5%, 40·8-67·3) had stable disease; 56 (91·8%, 81·9-97·3) of patients achieved disease control. The most common grade 3-4 treatment-associated adverse events were neutropenia (84 [78%] of 108 patients), increased alanine aminotransferase concentration (42 [39%]), thrombocytopenia (40 [37%]), anaemia (29 [27%]), febrile neutropenia (26 [24%]), and fatigue (21 [19%]). INTERPRETATION: Despite expected but manageable toxic effects, these results support the activity of doxorubicin plus trabectedin as first-line treatment for uterine leiomyosarcoma and soft-tissue leiomyosarcoma. This combination should be developed further in a phase 3 trial against the present standard of care. FUNDING: Pharmamar and Amgen.

Interruption versus continuation of trabectedin in patients with soft-tissue sarcoma (T-DIS): a randomised phase 2 trial.

BACKGROUND: The benefit or harm of trabectedin discontinuation in patients with non-progressive soft-tissue sarcoma remains unclear. We report the final analysis of a phase 2 trial investigating the clinical benefit of continuation of trabectedin treatment until progression versus interruption of therapy after six treatment cycles in patients with advanced soft-tissue sarcoma. METHODS: For this open-label, non-comparative, multicentre, phase 2 study, eligible adult patients with advanced soft-tissue sarcomas, who had previously received doxorubicin-based chemotherapy and were able to receive trabectedin, were enrolled from 14 centres of the French Sarcoma Group. Trabectedin was administered at a dose of 1·5 mg/m(2) through a central venous line as a 24-h continuous infusion every 3 weeks. After the initial six cycles of trabectedin, patients who were free from progressive disease were randomly assigned in a 1:1 ratio either to continuous treatment or therapy interruption. Randomisation was done centrally by a computer-generated system using permuted blocks of four patients, stratified by tumour grade and performance status. Patients allocated to the interruption group were allowed to restart trabectedin in case of progressive disease. The primary endpoint was progression-free survival at 6 months after randomisation, analysed by intention to treat. This study is registered with ClinicalTrials.gov, number NCT01303094. RESULTS: In 178 evaluable patients, 91 (51%) patients had not progressed after six cycles. Of these patients, 53 patients were randomly assigned to the two treatment groups: 27 to the continuation group and 26 to the interruption group. Overall, patients in the two groups received a similar median number of trabectedin cycles (continuation group: 11 cycles [range 6-31+] vs interruption group: 11 [range 6-23+]). After randomisation, progression-free survival at 6 months was 51·9% (95% CI 31·9-68·6) in the continuation group versus 23·1% (9·4-40·3) in the interruption group (p=0·0200). The occurrence of treatment-related grade 3 adverse events (four [16%] of 25 patients in the continuation group vs three [14%] of 21 in the interruption group) and grade 4 adverse events (one [4%] vs none) was similar in both groups. The most common grade 3 and 4 toxicities were alanine aminotransferase or aspartate aminotransferase increases (one [4%] in the interruption group vs three [14%] in the continuation group), neutropenia (two [8%] vs two [10%]), and intestinal occlusion (one [4%] vs one [5%]). INTERPRETATION: We do not recommend trabectedin discontinuation in patients with advanced, doxorubicin-refractory soft-tissue sarcoma who have not progressed after six cycles of treatment.

Prognostic factors and impact of adjuvant treatments on local and metastatic relapse of soft-tissue sarcoma patients in the competing risks setting.

BACKGROUND: In the medical literature many analyses of outcomes of sarcoma patients were performed without regard to the problem of "competing risks." METHODS: We analyzed local relapse-free and metastasis-free survival in a population of 3255 adult patients with a primary soft-tissue sarcoma (STS) included in the French Sarcoma Group database. Cumulative incidence of local and metastatic relapse was estimated by accounting for death as a competing event. RESULTS: On multivariate analysis, age, tumor site, histological subtype, and grade were independent adverse prognostic factors for local relapse, whereas tumor depth and size had no influence. Histological subtype, tumor depth, tumor size, and grade were independent adverse prognostic factors for metastatic relapse. Despite a higher incidence of competing deaths in patients managed with adjuvant radiotherapy than in patients not receiving radiotherapy, adjuvant radiotherapy was associated with a significant benefit in terms of local relapse-free survival. Despite a similar cumulative incidence of competing deaths in patients with grade 2 and grade 3 disease, we found that the benefit of adjuvant chemotherapy was present only in patients with grade 3 and not in patients with grade 2 disease. CONCLUSIONS: In the setting of competing risks, tumor biology reflected by histological grade is a crucial predictor of local relapse, whereas tumor depth and size have poor if any influence. Grade could also predict the benefit of adjuvant chemotherapy in patients with STS.

Long-term recurrence of soft tissue sarcomas: prognostic factors and implications for prolonged follow-up.

BACKGROUND: To the authors' knowledge, the incidence of late recurrence (> 5 years after initial management) is unknown and no prognostic factors for late events have been characterized in patients with soft tissue sarcomas. METHODS: Follow-up data from patients with localized soft tissue sarcoma who were included in the French Sarcoma Group database from January 1990 to June 2005 were reviewed. The outcomes of interest were the cumulative probabilities of late (> 5 years) local and metastatic disease recurrence with death as a competing event. Estimations and 95% confidence intervals (95% CIs) were computed with the cumulative incidence function. RESULTS: A total of 719 patients who were alive and event free > 5 years after their initial diagnosis were included in the current study. Sixty-seven patients (9.3%) developed a late local recurrence and 42 patients (5.8%) developed a late metastatic recurrence, respectively. On multivariate analysis, internal trunk location (hazard ratio [HR], 3.9; 95% CI, 2.2-6.7 [P < .001]) and tumor size > 100 mm (HR, 2.1; 95% CI, 1.1-4 [P = .035]) were the 2 factors found to be independently associated with an increased risk of late local recurrence. Grade > 1 (graded according to the French Federation of Cancer Centers Sarcoma Group) (HR, 4.7; 95% CI 1.1-21 [P = .04]) was the sole factor found to be independently associated with an increased risk of late metastatic recurrence. CONCLUSIONS: Late recurrence of soft tissue sarcoma is relatively uncommon. However, the results of the current study emphasize the critical role of long-term follow-up to detect late local disease recurrence in patients with retroperitoneal or very large soft tissue sarcomas, and late metastatic recurrence in patients with high-grade disease. Conversely, the prolonged follow-up of patients with grade 1 disease is not needed.

Does COVID-19 pandemic impact cancer outcomes in metastatic setting? A comparative cohort study among metastatic patients treated at day care hospital.

INTRODUCTION: COVID-19 outbreak rapidly spread since early 2020 leading to the implementation of nationwide lockdowns. To cope with this sudden change, management guidelines were quickly published to adapt oncological care, with potential impact on cancer outcomes. METHODS: We conducted a retrospective comparative cohort study to assess the impact of the COVID-19 outbreak in 2020 on cancer outcomes in metastatic patients. Two cohorts of metastatic patients receiving intravenous (iv) therapy in a French oncological day care hospital were assessed: a 2020 cohort during the first French lockdown, and a 2018 historical cohort before the COVID-19 pandemic. We performed a propensity score analysis to match patients from the two cohorts. After one-year follow-up, we compared progression-free survival (PFS) and overall survival (OS) between cohorts. Adaptations of medical oncological treatments in 2020 were also analysed. RESULTS: The 376 patients of the 2020 cohort were matched with 376 of the 2018 cohort. No SARS-CoV-2 infection was observed in the 2020 cohort. The adjusted PFS was significantly shorter in 2020 compared to 2018 (HR = 1.23; 95% CI: 1.03-1.46), as well as among patients without treatment adaptation compared to matched patients of the 2018 cohort (HR = 1.33; 95% CI: 1.10-1.61). We did not observe any significant difference of PFS among the group with treatment adaptations. OS was not significantly different. CONCLUSION: Metastatic cancer patients treated during the first lockdown had a higher risk of disease progression 1 year after COVID-19 outbreak. However, oncological treatment adaptations or SARS-CoV-2 infections do not explain these results. A longer follow-up is needed to observe the impact on OS.

Comparison of doxorubicin and weekly paclitaxel efficacy in metastatic angiosarcomas.

BACKGROUND: Data regarding the role of anthracyclines and taxanes as first-line treatments of metastatic angiosarcoma are limited. METHODS: Records of 117 metastatic angiosarcoma patients who were treated with either doxorubicin or weekly paclitaxel were reviewed. RESULTS: Seventy-five patients (64%) were treated with weekly paclitaxel and 42 (36%) with single-agent doxorubicin. Patients in the weekly paclitaxel group were older and more frequently had angiosarcomas arising from the skin. In the doxorubicin group, 34 patients were evaluable for response: 2 (6%) had complete response, 8 (23.5%) had partial response, 10 (29.5%) had stable disease, and 14 (41%) had progressive disease. In the weekly paclitaxel group, 68 patients were evaluable for response: 9 (13%) had complete response, 27 (40%) had partial response, 20 (29.5%) had stable disease, and 12 (17.5%) had progressive disease. Objective responses to weekly paclitaxel were more frequent in cutaneous angiosarcomas, whereas tumor location did not impact response to doxorubicin. Median progression-free survival (PFS) was 4.9 months (95% confidence interval [95% CI], 3.9-6.0 months). Median overall survival (OS) was 8.5 months (95% CI, 6.4-10.7 months). On multivariate analysis, ECOG performance status (PS) was the sole independent factor associated with PFS and OS. CONCLUSIONS: First-line single-agent doxorubicin and weekly paclitaxel seem to have similar efficacy in metastatic angiosarcomas. Cutaneous angiosarcomas respond favorably to weekly paclitaxel. Best supportive care should be considered in patients with poor PS.

Randomized multicenter and stratified phase II study of gemcitabine alone versus gemcitabine and docetaxel in patients with metastatic or relapsed leiomyosarcomas: a Federation Nationale des Centres de Lutte Contre le Cancer (FNCLCC) French Sarcoma Group Study (TAXOGEM study).

BACKGROUND: This study aimed to evaluate the efficacy and toxicity of single-agent gemcitabine versus gemcitabine plus docetaxel as second-line therapy in patients with uterine and nonuterine leiomyosarcoma (LMS). PATIENTS AND METHODS: Patients had metastatic or unresectable LMS and had received one prior anthracycline-based regimen. A total of 90 patients received either single-agent gemcitabine (arm A; gemcitabine, 1,000 mg/m(2) i.v. for 100 minutes on days 1, 8, and 15 of a 28-day cycle) or a combination of gemcitabine and docetaxel (arm B; gemcitabine, 900 mg/m(2) i.v. for 90 minutes on days 1 and 8, plus docetaxel, 100 mg/m(2) i.v. for 1 hour on day 8 of a 21-day cycle with lenograstim). The primary endpoint was the objective response rate. RESULTS: The objective response rates were 19% and 24% in arm A (gemcitabine) and arm B (gemcitabine plus docetaxel), respectively, for patients with uterine LMS. For patients with nonuterine LMS, the objective response rates were 14% and 5% for arms A and B, respectively. The median progression-free survival times for arms A and B were 5.5 months and 4.7 months, respectively, for patients with uterine LMS. For patients with nonuterine LMS, the median progression-free survival times were 6.3 months and 3.8 months for arms A and B, respectively. One toxic death occurred in arm B. CONCLUSIONS: Both single-agent gemcitabine and gemcitabine plus docetaxel were found to be effective second-line therapies for leiomyosarcomas, with a 3-month progression-free survival rate of 40% for LMS with both uterine and nonuterine sites of origin. Single-agent gemcitabine yielded results similar to those of gemcitabine plus docetaxel in this trial, but patients using single-agent gemcitabine experienced less toxicity.

[Management of adverse effects of targeted therapy toxicities in oncology]. / Principes de prise en charge des effets indésirables des thérapies ciblées en cancérologie.

During the past few years, medical treatments of cancer have improved thanks to the discovery of targeted therapies. These therapies are today widely used in cancer treatment. The mechanism of action of targeted therapies and the adverse effects they induce are different from the classic chemotherapies, and require a specific management. Most of these drugs are taken at home and orally, and as a consequence, general practitioners should be able to manage these side effects. The most current toxicities in general medicine are fatigue, high blood pressure, dermatologic, gastrointestinal and metabolic side effects. These effects, often moderate are frequent and diverse, and can impact the patient's quality of life and reduce treatment compliance. Management of these toxicities should then be well known by general practitioners in order to optimize care and improve patient wellness.

Supervised Physical Activity Quickly Improves Social Dimension of Quality of Life in Breast Cancer Patients.

PURPOSE: The objectives of the present study was to evaluate the implementation of the program in real life and the evolution of the quality of life (QoL) in breast cancer patients after 3 months of supervised PA in real life and to determine the factors associated with changes in various QoL dimensions. METHODS: This prospective cohort study was carried out in female patients with breast cancer diagnosed within a maximum of 3 yr. QoL and physical exertion intensity during the supervised physical activity (PA) sessions were assessed by the Quality of Life Questionnaire for Cancer and Borg scale, respectively. Statistical analyses comparing QoL scores between the start and the end of supervised PA program were assessed using paired Student's t -tests. Multivariate analysis was performed by linear regression with only variables with a P value <0.15 in univariate model. RESULTS: A total of 93 patients were included in the analyses. There was a significant improvement of social functioning at T3 (∆ = 11.5; P < 0.001). The improvement of social functioning was significantly and independently associated with the Borg improvement ( ß = 2.66 ± 1.31, P = 0.046), chemotherapy ( ß = 11.03 ± 5.45, P = 0.046), hormone therapy ( ß = -13.91 ± 5.51, P = 0.013), social isolation ( ß = -14.81 ± 6.55, P = 0.026), and comorbidities ( ß = -15.32 ± 5.59, P = 0.007). CONCLUSIONS: We observed a real enthusiasm and need among patients for practicing PA supervised by a sport trainer near their home. The increase in the intensity of exercise over time contributes to the improvement of the QoL, especially on the social functioning. These results, consistent with previous literature, reinforce the importance of exercise intensity on many dimensions of QoL. In addition, patients expressed great satisfaction with the supervised program, resulting in a strong desire to maintain long-term PA.

Efficacy and safety of regorafenib in patients with metastatic or locally advanced chondrosarcoma: Results of a non-comparative, randomised, double-blind, placebo controlled, multicentre phase II study.

BACKGROUND: This multi-cohort trial explored the efficacy and safety of regorafenib for patients with advanced sarcomas of bone origin; this report details the cohort of patients with metastatic or locally advanced chondrosarcoma (CS), progressing after prior chemotherapy. PATIENTS AND METHODS: Patients with CS, progressing despite prior standard therapy, were randomised (2:1) to receive regorafenib or placebo. Patients on placebo could crossover to receive regorafenib after centrally confirmed progressive disease. The primary endpoint was progression-free rate (PFR) at 12 weeks. With one-sided α of 0.05, and 80% power, at least 16/24 progression-free patients at 12 weeks were needed for success (P0 = 50%, P1 = 75%). RESULTS: From September 2014 to February 2019, 46 patients were included in the CS cohort, and 40 patients were evaluable for efficacy: 16 on placebo and 24 on regorafenib. Thirteen patients (54.2%; 95% CI [35.8%-[) were non-progressive at 12 weeks on regorafenib versus 5 (31.3%; 95% CI [13.2%-[);) on placebo. Median PFS was 19.9 weeks on regorafenib, and 8.0 on placebo. Fourteen placebo patients crossed over to regorafenib after progression. The most common grade ≥3 treatment-related adverse events on regorafenib included hypertension (12%), asthenia (8%), thrombocytopenia (8%) and diarrhoea (8%). One episode of fatal liver dysfunction occurred on regorafenib. CONCLUSION: Although the primary endpoint was not met statistically in this small randomised cohort, there is modest evidence to suggest that regorafenib might slow disease progression in patients with metastatic CS after the failure of prior chemotherapy. CLINICAL TRIAL REGISTRATION: The trial is registered at ClinicalTrials.gov (NCT02389244).

Methotrexate-Etoposide-Ifosfamide Compared with Doxorubicin-Cisplatin-Ifosfamide Chemotherapy in Osteosarcoma Treatment, Patients Aged 18-25 Years.

Purpose: The French standard chemotherapy for osteosarcoma combines high-dose methotrexate (HDM) and etoposide-ifosfamide (EI) in children and adolescents, and API-AI (doxorubicin-cisplatin-ifosfamide) in adults. We herein present the results of M-EI and API-AI in 18- to 25-year-old patients. Methods: Patients, 18-25 years old, received either M-EI or API-AI regimens. M-EI comprised seven M and two EI doses preoperatively then M-EI in standard-risk patients (good histological response without metastasis) and five M-AP (methotrexate-doxorubicin-cisplatin) in high-risk patients (poor histological response, metastasis, and/or unresectable primary), postoperatively. API-AI comprised three API and two AI doses preoperatively, then two AI and two PI in standard-risk patients and five EI in high-risk patients, postoperatively. Results: We analyzed 95 patients 18-25 years of age: 55 received M-EI and 40 API-AI. The groups had similar baseline characteristics. Eighty-nine patients (94%) had surgery. Twenty-nine of 55 M-EI patients (60%) and 16/40 API-AI patients (41%) had good histological responses to preoperative chemotherapy. At 5 years, event-free survival was 50% (95% confidence interval [CI]: 39-60) and overall survival was 65% (95% CI: 54-74). Acute toxicity was similar, without treatment-related deaths. Conclusions: Survival outcomes with M-EI and API-AI were not significantly different. Tolerance was acceptable with both regimens. HDM is thus feasible for young adults. However, our study limitations preclude any definitive conclusions.

A double-blind placebo-controlled randomized phase II trial assessing the activity and safety of regorafenib in non-adipocytic sarcoma patients previously treated with both chemotherapy and pazopanib.

BACKGROUND: Metastatic soft tissue sarcomas (STSs) management remains an unmet medical need. We assessed the activity and safety of regorafenib in patients with metastatic non-adipocytic STS who were previously treated with both chemotherapy and pazopanib. PATIENTS AND METHODS: This double-blind, placebo-controlled, multicenter comparative randomized phase II trial included patients with histologically proven advanced and inoperable STS. Patients receiving placebo were offered optional cross-over for centrally confirmed disease progression. Primary end-point was centrally reviewed Response Evaluation Criteria in Solid Tumours-based progression-free survival (PFS), analysed on the intent-to-treat data set. In total, 24 events were required for 90% power, hazard ratio (HR) = 0.33 (median PFS, 3.6 versus 1.2 months), and 1-sided α = 0.1 (ClinicalTrials.gov, NCT01900743). RESULTS: From December 2015 to October 2017, 37 patients were randomized; 18 to regorafenib and 19 to placebo. Thirteen patients assigned to placebo switched to regorafenib after progression. Median follow-up was 27.2 months (95% confidence interval [CI]: 24.4-not reached). We observed a significant PFS benefit of regorafenib compared with placebo (adjusted HR = 0.33; 95% CI: 0.15-0.74; p = 0.0007 median PFS = 2.1 versus 1.1 months, respectively), and a large and nearly significant overall survival (OS) benefit despite the cross-over (adjusted HR = 0.49; 95% CI: 0.23-1.06; p = 0.007; median OS = 17.8 versus 8.2 months). Before cross-over, the most common grade III or higher adverse events were lymphopenia (5 versus 1, respectively), diarrhoea (4 versus 0), dyspnoea (3 versus 1), skin toxicity (3 versus 0), arterial hypertension (2 versus 0), and increased transaminases (2 versus 0). CONCLUSION: The present study demonstrated a meaningful clinical anti-tumour activity with regorafenib in heavily pre-treated patients with non-adipocytic STS.
