RESUMEN
BACKGROUND: The modified docetaxel, cisplatin, and fluorouracil (mDCF) regimen has shown efficacy and safety as first-line treatment for advanced squamous cell carcinoma of the anus, making it a standard regimen. Inhibitors of programmed cell death protein 1 and its ligand, such as pembrolizumab, nivolumab, retifanlimab, avelumab, and atezolizumab, have shown some antitumour activity as monotherapy in advanced squamous cell carcinoma of the anus that is refractory to chemotherapy. This phase 2 study evaluated the combination of mDCF and atezolizumab as first-line treatment in advanced squamous cell carcinoma of the anus. METHODS: In this randomised, open-label, non-comparative, phase 2 study, participants from 21 centres (academic, private, and community hospitals and cancer research centres) across France with chemo-naive, metastatic, or unresectable locally advanced recurrent squamous cell carcinoma of the anus, aged 18 years or older, and with an Eastern Cooperative Oncology Group performance status of 0 or 1, were randomly allocated (2:1) to receive either atezolizumab (800 mg intravenously every 2 weeks up to 1 year) plus mDCF (eight cycles of 40 mg per m2 docetaxel and 40 mg per m2 cisplatin on day 1 and 1200 mg per m2 per day of fluorouracil for 2 days, every 2 weeks intravenously; group A) or mDCF alone (group B). Randomisation was done centrally using a minimisation technique and was stratified by age (<65 years vs ≥65 years) and disease status. The primary endpoint was investigator-assessed 12-month progression-free survival in the modified intention-to-treat population in group A (35% for the null hypothesis and 50% for the alternative hypothesis). This trial is registered with ClinicalTrials.gov, NCT03519295, and is closed to new participants. FINDINGS: 97 evaluable participants (64 in group A and 33 in group B) were enrolled between July 3, 2018, and Aug 19, 2020. The median follow-up was 26·5 months (95% CI 24·8-28·4). The median age of participants was 64·1 years (IQR 56·2-71·6), and 71 (73%) were female. 12-month progression-free survival was 45% (90% CI 35-55) in group A and 43% (29-58) in group B. In participants with a PD-L1 combined positive score of 5 or greater, 12-month progression-free survival was 70% (95% CI 47-100) in group A and 40% (19-85) in group B (interaction p=0·051) Both groups showed high compliance. Adverse events of grade 3 or higher were observed in 39 (61%) participants in group A and 14 (42%) in group B. The most common grade 3-4 adverse events were neutropenia (nine [14%] participants in group A vs five [15%] in group B), anaemia (nine [14%] vs one [3%]), fatigue (three [5%] vs four [12%]), and diarrhoea (seven [11%] vs one [3%]). Serious adverse events occurred in 16 (25%) participants in group A and four (12%) in group B, and these were mDCF-related in seven (11%) participants in group A and four (12%) in group B. Atezolizumab-related serious adverse events occurred in nine (14%) participants in group A, including grade 2 infusion-related reaction in three (5%), grade 3 infection in two (3%), and grade 2 colitis, grade 3 acute kidney injury, grade 3 sarcoidosis, and a grade 4 platelet count decrease each in one participant (2%). There were no treatment-related deaths. INTERPRETATION: Despite a higher incidence of adverse events, combining atezolizumab with mDCF is feasible, with similar dose intensity in both groups, although the primary efficacy endpoint was not met. The predictive value of a PD-L1 combined positive score of 5 or greater now needs to be confirmed in future studies. FUNDING: GERCOR, Roche.

The management of anal squamous cell carcinoma (ASCC) has yet to experience the transformative impact of precision medicine. Conducting genomic analyses may uncover novel prognostic biomarkers and offer potential directions for the development of targeted therapies. To that end, we assessed the prognostic and theragnostic implications of pathogenic variants identified in 571 cancer-related genes from surgical samples collected from a homogeneous, multicentric French cohort of 158 ASCC patients who underwent abdominoperineal resection treatment. Alterations in PI3K/AKT/mTOR, chromatin remodeling, and Notch pathways were frequent in HPV-positive tumors, while HPV-negative tumors often harbored variants in cell cycle regulation and genome integrity maintenance genes (e.g., frequent TP53 and TERT promoter mutations). In patients with HPV-positive tumors, KMT2C and PIK3CA exon 9/20 pathogenic variants were associated with worse overall survival in multivariate analysis (Hazard ratio (HR)KMT2C = 2.54, 95%CI = [1.25,5.17], P value = .010; HRPIK3CA = 2.43, 95%CI = [1.3,4.56], P value = .006). Alterations with theragnostic value in another cancer type was detected in 43% of patients. These results suggest that PIK3CA and KMT2C pathogenic variants are independent prognostic factors in patients with ASCC with HPV-positive tumors treated by abdominoperineal resection. And, importantly, the high prevalence of alterations bearing potential theragnostic value strongly supports the use of genomic profiling to allow patient enrollment in precision medicine clinical trials.

In a previous phase II study (THERAPY), cetuximab and trastuzumab combination, as second-line after progression with gemcitabine, showed disease stabilization in 27% of 33 patients with pancreatic carcinoma. In the present phase II multicenter study, we assessed the efficacy and tolerance of gemcitabine, trastuzumab plus erlotinib as first-line treatment of metastatic pancreatic cancer. The primary endpoint was disease control rate (DCR, RECIST v.1); secondary endpoints were progression-free (PFS), overall (OS) survival and toxicity (NCI-CTCAE v3.0). Ancillary study addressed the predictive value of both EGFR/HER2 expression and KRAS mutational status. Sixty-three patients from four centers were included (62 evaluable for toxicity, 59 for efficacy), median age was 62 years (35-77), 59.7% men. The median treatment duration was 16.1 weeks (2.1-61). Eleven patients (19%) reported a partial tumor response, and 33 (56%) disease stabilization. DCR was 74.6% (95%CI: 61.8-85.0; 44/59 patients). After a median follow-up of 23.3 months (0.6-23.6), median PFS was 3.5 months (95%CI: 2.4-3.8) and median OS 7.9 months (95%CI: 5.1-10.2). PFS was significantly longer in patients with grade ≥ 2 cutaneous toxicities vs patients with grade 0-1 toxicities (HR = 0.55, 95%CI: 0.33-0.92, P = .020). Expression of EGFR and HER2 was correlated with PFS and OS in multivariate analysis; HER2 expression was correlated with the tumor response. Main severe toxicities were neutropenia (32%), cutaneous rash (37%) and thrombosis/embolisms (35.5%). This triplet combination is effective in terms of disease control, PFS and OS, and acceptable for safety. A larger study to investigate this combination compared to the standard regimen should be discussed.

BACKGROUND: Modified docetaxel, cisplatin, and 5-fluorouracil (mDCF) regimen has become a new standard for the treatment of metastatic or unresectable locally advanced recurrent squamous cell carcinoma of the anus (SCCA) after demonstrating improved efficacy (12-month PFS of 47%) in the Epitopes-HPV02 trial. Antibodies targeting the checkpoint inhibitor (CKI) programmed cell death protein-1 (PD1) have demonstrated the efficacy as monotherapies in second-line treatment of SCCA. The aim of this study is to evaluate the combination of atezolizumab and mDCF as first-line chemotherapy in a non-comparative multicentre randomized phase II study of advanced SCCA patients. METHODS: Patients with chemo-naive advanced histologically proven SCCA, metastatic or unresectable locally advanced recurrence, and Eastern Cooperative Oncology Group-performance status (ECOG-PS) < 2 will be eligible. The primary endpoint is a 12-month PFS rate. Using one-arm non-parametric survival with unilateral alpha type I error of 5% and a statistical power of 80%, the upper critical value for the 12-month PFS rate is 47% to reject H0. Assuming 5% lost to follow-up, 99 patients will be randomized on a 2:1 basis, 66 to the experimental arm (arm A, mDCF plus atezolizumab) and 33 to the standard arm (arm B, mDCF). In both arms, 8 cycles of mDCF will be administered. In arm A, patients receive mDCF with a fixed dose of atezolizumab (800 mg every 2 weeks) and are followed up to 1 year. Secondary endpoints are overall survival, PFS, response rate, safety, health-related quality of life, and an extensive biomarker programme and its correlation with the treatment efficacy. DISCUSSION: Although the Epitopes-HPV02 trial has changed long-lasting prognosis of patients with SCCA in advanced stage disease, more than 50% of patients will progress at 12 months. The purpose of the SCARCE trial to establish the addition of atezolizumab to mDCF as a new standard in this rare disease. Associated biomarker studies and the control arm could contribute to better understanding of the potential synergic and tumour resistance mechanisms in SCCA. TRIAL REGISTRATION: NCT03519295.

BACKGROUND: The correlation between immune cells and the Lauren classification subtypes and their prognostic impact in advanced gastric cancer (AGC) are unknown. METHODS: Circulating natural killer (NK) cells, CD4+ and CD8+ T cells, regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSCs) were quantified in peripheral blood mononuclear cells (PBMCs) from 67 patients with untreated AGC enrolled in the PRODIGE 17-ACCORD 20 trial. CD56+ cells (NK), CD8+, and FoxP3+ (Treg) tumor-infiltrating lymphocytes (TILs) were assessed in tumor samples. RESULTS: Circulating NK and Treg proportions were significantly lower in patients with diffuse/mixed-type AGC (n = 27) than those with intestinal type (n = 40; median 6.3% vs 11.5%; p = 0.02 and median 3.3% vs 5.2%; p = 0.03, respectively). Proportions of circulating MDSC, CD4+ and CD8+ T cells were not associated with one pathological type. Among tumor-infiltrating cells, CD8+ T cells, but not NK or FoxP3+ cells, were significantly lower in diffuse/mixed-type AGC (median 21 vs 59 cells/field; p = 0.009). Patients with high circulating NK cell counts (> 17%) had a better overall survival than those with < 17% (HR 0.40; 95% CI [0.15-1.06]; p = 0.04). Patients with high CD8+ TIL counts (> 31 cells/field) had significantly longer overall survival (HR 0.44; 95% CI [0.21-0.92]; p = 0.02). The prognostic value of CD8+ TILs was maintained after adjustment for confounding factors, including the Lauren classification (HR = 0.42; 95% CI [0.18-0.96]; p = 0.039). CONCLUSION: Diffuse/mixed-type AGC has lower rates of CD8+ TILs and circulating NK cells and Tregs than the intestinal type. This "cold tumor" phenotype may be associated with a worse outcome.

BACKGROUND: The incidence of anal squamous cell carcinoma has been increasing markedly in the past few decades. Currently, there is no validated treatment for advanced-stage anal squamous cell carcinoma. Therefore, we aimed to validate the clinical activity and safety of docetaxel, cisplatin, and fluorouracil (DCF) chemotherapy in patients with metastatic or unresectable locally recurrent anal squamous cell carcinoma. METHODS: We did a multicentre, single-arm, phase 2 study. We recruited patients from 25 academic hospitals, cancer research centres, and community hospitals in France who were aged 18 years or older with histologically confirmed anal squamous cell carcinoma, with metastatic disease or with unresectable local recurrence; an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1; and with at least one evaluable lesion according to the Response Evaluation Criteria in Solid Tumors (version 1.1). Chemotherapy-naive patients received either six cycles of standard DCF (75 mg/m2 docetaxel and 75 mg/m2 cisplatin on day 1 and 750 mg/m2 per day of fluorouracil for 5 days, every 3 weeks) or eight cycles of modified DCF (40 mg/m2 docetaxel and 40 mg/m2 cisplatin on day 1 and 1200 mg/m2 per day of fluorouracil for 2 days, every 2 weeks), which were administered intravenously. The choice between the standard versus modified regimens was recommended based on, but not limited to, age (≤75 years vs >75 years) and ECOG performance status (0 vs 1). The primary endpoint was investigator-assessed progression-free survival at 12 months from the first DCF cycle; for the primary endpoint to be met, at least 11 (17%) of 66 enrolled patients had to be alive without disease progression at 12 months. Efficacy and safety analyses were done in a modified intention-to-treat population, defined as all patients who were evaluable for progression at 12 months who received at least one cycle of DCF. This trial is registered at ClinicalTrials.gov, number NCT02402842, and the final results are presented here. FINDINGS: Between Sept 17, 2014, and Dec 7, 2016, we enrolled 69 patients. Of these patients, three did not receive DCF. Of the 66 patients who received treatment, 36 received the standard DCF regimen and 30 received modified DCF. The primary endpoint was met: 31 (47%) of 66 patients were alive and progression free at 12 months. 22 (61%) of 36 patients who received the standard DCF regimen and 18 (60%) of 30 patients who received the modified DCF regimen had disease progression at data cutoff. 46 (70%) of 66 patients had at least one grade 3-4 adverse event (30 [83%] of 36 in the standard DCF regimen and 16 [53%] of 30 in the modified DCF regimen). The most common grade 3-4 adverse events were neutropenia (15 [23%]; eight [22%] for standard DCF vs seven [23%] for modified DCF), diarrhoea (12 [18%]; nine [25%] vs three [10%]), asthenia (ten [15%]; eight [22%] vs two [7%]), anaemia (ten [15%]; six [17%] vs four [13%]), lymphopenia (eight [12%]; three [8%] vs five [17%]), mucositis (seven [11%]; seven [19%] vs none), and vomiting (seven [11%]; five [14%] vs two [7%]). No grade 4 non-haematological adverse events and febrile neutropenia were observed with modified DCF, whereas three (8%) grade 4 non-haematological adverse events and five (14%) cases of febrile neutropenia were reported with standard DCF. 97 serious adverse events were reported (69 in patients who received the standard DCF regimen [61 drug-related] and 28 in those given the modified DCF regimen [14 drug-related]). No treatment-related deaths were recorded. INTERPRETATION: Compared with standard DCF, modified DCF provided long-lasting response with good tolerability in patients with metastatic or unresectable locally recurrent anal squamous cell carcinoma with ECOG performance status of 0-1 in the first-line setting, and therefore could be considered as a new standard of care for these patients. Regarding the elevated risk of high-grade and serious adverse events and febrile neutropenia, standard DCF cannot be recommended in this situation.

People with intellectual disabilities (PWIDs) are now living longer; thus, the incidence of cancer within this population is increasing. Available data indicate an excess of digestive tract cancers in PWIDs, but colorectal cancer has rarely been specifically studied and has not been extensively reviewed. This is despite risk factors such as being overweight, obesity, and lack of exercise being more frequent in PWIDs. In this article, we examine the literature on the frequency, screening, and treatment of colorectal cancer in PWIDs by as sessing 4 databases, Medline, EBSCO-CINHL, ASSIA, and PsychLIT, from 1970 to February 2017. Findings indicate that the frequency trends slightly higher than that found in the general population. Screening presents a unique opportunity to discover early colorectal cancer, but is underused in PWIDs compared to the general population. Furthermore, the clinical presentation is frequently masked, particularly by challenging behaviours, and colorectal cancer is therefore often diagnosed late, making treatment difficult due to the advanced stage of these tumours. To improve the care of PWIDs, we need more resources to support them and their caregivers, and to increase awareness of the risk factors and signs and symptoms of colorectal cancer.

BACKGROUND: The squamous cell carcinoma of the anus (SCCA) is a rare disease, but its incidence is markedly increasing. About 15% of patients are diagnosed at metastatic stage, and more than 20% with a localized disease treated by chemoradiotherapy (CRT) will recur. In advanced SCCA, cisplatin and 5-fluorouracil (CF) combination is the standard option but complete response is a rare event and the prognosis remains poor with most disease progression occurring within the first 12 months. We have previously published the potential role of the addition of docetaxel (D). Among 8 consecutive patients with advanced recurrent SCCA after CRT, the DCF regimen induced a complete response in 4 patients, including 3 pathological complete responses. Then, the Epitopes-HPV02 study was designed to confirm the interest of DCF regimen in SCCA patients. METHODS: This multicentre phase II trial assesses the DCF regimen in advanced SCCA patients. Main eligibility criteria are: histologically proven SCCA, unresectable locally advanced recurrent or metastatic disease, Eastern Cooperative Oncology Group-performance status (ECOG-PS) <2, and being eligible for DCF. Patients receive either 6 cycles of standard DCF or 8 cycles of modified DCF depending on age (> vs. ≤ 75 years-old) and ECOG-PS (0 vs. 1). The trial was set up based on a Simon's optimal two-stage design for phase II trials, allowing an early futility interim analysis. The primary endpoint is the observed progression-free survival (PFS) rate at 12 months from the first DCF cycle. A PFS rate below 10% is considered uninteresting, while a PFS rate above 25% is expected. With a unilateral alpha error of 5% and a statistical power of 90%, 66 evaluable patients should be included. Main secondary endpoints are overall survival, PFS, response rate, safety, health-related quality of life, and the correlation of biomarkers with treatment efficacy. DISCUSSION: Since the recommended CF regimen is based in a small retrospective analysis and generates a low rate of complete responses, the Epitopes-HPV02 study will establish a new standard in case of a positive result. Associated biomarker studies will contribute to understand the underlying mechanism of resistance and the role of immunity in SCCA. TRIAL REGISTRATION: NCT02402842 , EudraCT: 2014-001789-81.

OBJECTIVE: This study aimed to identify predictors of tumor control (TC) in metastatic esophageal squamous cell carcinoma patients receiving first-line chemotherapy. METHODS: A development cohort of 68 patients from a prospective multicenter trial (NCT01248299) was used to identify predictors of TC at first radiological tumor assessment and to generate a predictive score for TC. That score was applied in an independent retrospective single-center validation cohort of 60 consecutive patients. RESULTS: Multivariate analysis identified three predictors of TC: body mass index ≥18.5 (OR 4.5, 95% CI 0.91-22.5), absence of bone metastasis (OR 4.6, 95% CI 0.91-23.2) and albumin ≥35 g/l (OR 3.5, 95% CI 1.0-12.1). Based on the presence or absence of these three independent prognosticators, we built a predictive model using a score from 0 to 3. In the development cohort, the TC rates were 14.3 and 78.0% and in the validation cohort 12.5 and 44.2%, for scores of 0-1 and 2-3, respectively. With negative predictive values of 85 and 88% in the development and validation cohorts, respectively, we were able to identify patients with a very low probability of TC. CONCLUSION: We have developed and validated a score that can be easily determined at the bedside to predict TC in metastatic esophageal squamous cell carcinoma patients.

BACKGROUND: Docetaxel-cisplatin-5-FU chemotherapy is superior to 5-FU-cisplatin in terms of response rate and survival in advanced gastric cancer (AGC), but is more toxic. Oxaliplatin is better tolerated than cisplatin, which it can effectively replace in this setting. We hypothesize that incorporating docetaxel into a simplified FOLFOX regimen should be a tolerable and effective option in first-line treatment of AGC. METHODS: Data were collected at six French centers from patients with metastatic or local AGC who received docetaxel, fluorouracil, leucovorin, or oxaliplatin (TEF) as first-line treatment. TEF was administered as follows: docetaxel (50 mg/m(2)), oxaliplatin (85 mg/m(2)), and leucovorin (40 mg/m(2)) on day 1, and 5-FU continuous infusion for 48 h (2400 mg/m(2)) every 2 weeks. RESULTS: Forty-one patients were enrolled. Performance status was grade 0 and 1 in respectively 27 and 58 % of patients; 17 patients had adenocarcinoma of the gastroesophageal junction; 37 patients had metastatic disease, 22 had a poorly differentiated or diffuse type. Objective response rate was 66 %, with a complete response in two patients (5 %). Median progression-free survival and overall survival were respectively 6.3 and 12.1 months. Tolerability was acceptable with no treatment-related deaths. The most frequent grade 3-4 toxicities were neutropenia (30 %) and neuropathy (12.5 %). Curative intent surgery after response to TEF was performed in seven patients (17 %). CONCLUSION: TEF is an effective first-line treatment with an acceptable toxicity profile for patients with AGC. It may allow curative resection in initially unresectable patients. TEF should now be evaluated in prospective randomized trials.

BACKGROUND: Triplet chemotherapy plus cetuximab showed promising results in phase II trials in unsystematically selected RAS population. We evaluated FOLFIRINOX+cetuximab efficacy as first-line treatment in extended RAS wild-type metastatic colorectal cancer (mCRC) patients. METHODS: We retrospectively analyzed patients treated with FOLFIRINOX+cetuximab, using data from clinical trials and real-life practice. Extended mutation analysis was performed when RAS/BRAF status was unavailable. The primary endpoint was progression-free survival (PFS). RESULTS: Seventy patients (61.4 % male, median age 58.7 years) were analyzed. Eighty percent had left-sided mCRC and 97.1 % had liver metastases. Median PFS and overall survival (OS) were 13.3 and 48.5 months, respectively. The objective response rate was 85.7 %, with 20 % complete response. Primary tumor location did not affect OS and PFS. BRAF wild-type patients (n = 65) had longer PFS (13.3 vs. 6.0 months; p = 0.005) and OS (50.1 vs. 21.2 months; p = 0.007) than BRAF mutated patients (n = 5, including four BRAFV600E). Median OS was significantly longer in resected patients (n = 39, 55.1 vs. 30.7 months; p = 0.030). Main toxicities were diarrhea (31.4 %) and neutropenia (21.4 %). CONCLUSION: FOLFIRINOX+cetuximab provides good PFS, high response rate and prolonged disease control in initially unresectable extended RAS wild-type mCRC. This combination is particularly interesting for selected patients with liver-limited disease eligible to secondary resection.

In 2010, the FOLFIRINOX regimen (bolus and infusional 5-fluorouracil, leucovorin, irinotecan, and oxaliplatin) emerged as a new option in patients with metastatic pancreatic cancer and a good performance status. However, at that time, some doubts were raised regarding safety issues. Similarly, no data on FOLFIRINOX were published in patients with unresectable/locally advanced or borderline resectable pancreatic cancer. This article presents the available experience with FOLFIRINOX outside clinical trials in metastatic and locally advanced pancreatic cancer patients. The safety of the regimen in patients with biliary stents and in previously treated patients is also described. FOLFIRINOX usage in clinical practice, including modification of the regimen (omission of bolus 5-fluorouracil; FOLFOXIRI regimen), is also presented. These data suggest that a phase III randomized study is warranted to further explore the role of FOLFIRINOX in locally advanced pancreatic cancer.

Gastric adenocarcinoma (GC) and gastroesophageal junction adenocarcinoma represent frequent and severe diseases whose management has radically changed over the last 10 years. With the advent of second- and third-line standard therapies for metastatic GC patients in the 2010s, the molecular dismemberment of the disease and positive trials with immunotherapy and targeted agents will mark the 2020s. New treatment options have emerged in the neoadjuvant, adjuvant, and metastatic setting. In addition to improved multimodal treatment in operable patients, new subgroups have emerged depending on molecular alterations (HER2, Microsatellite instability) or expression of specific proteins in the tumour (PDL1, Claudin 18.2) making immunohistochemistry central in profiling the tumour for an optimal individualised management. The aim of this review is to describe the current standards of management of early and late stage GC and the molecular markers needed today to optimally manage our patients together with future perspectives on this disease.

Triplet DCF (docetaxel, cisplatin and 5-flurouracil) and doublet CP/CF (carboplatin and paclitaxel/cisplatin and 5-fluorouracil) regimens were prospectively evaluated in advanced squamous anal cell carcinoma (SCCA), and validated as standard treatments. Even though the high efficacy and good tolerance of DCF regimen were confirmed in 3 independent prospective trials, doublet CP regimen is still recommended in several guidelines based in its better safety profile with similar efficacy compared to CF regimen. We performed a propensity score-adjusted method with inverse probability of treatment weighted (IPTW) and matched case control (MCC) comparison among patients with metastatic or non-resectable locally advanced recurrent SCCA, treated with chemotherapy as first line regimen. The primary endpoint was the overall survival (OS), and the secondary endpoint was the progression-free survival (PFS). 247 patients were included for analysis. 154 patients received DCF and 93 patients received a doublet regimen. The median OS was 32.3 months with DCF and 18.3 months with doublet regimens (HR 0.53, 95%CI 0.38-0.74; p = 0.0001), and the median PFS was 11.2 months with DCF versus 7.6 months with doublet regimens (HR 0.53, 95%CI 0.39-0.73; p < 0.0001). The hazard ratios by IPTW and MCC analyses were 0.411 (95% CI, 0.324-0.521; p < 0.0001) and 0.406 (95% CI, 0.261-0.632; p < 0.0001) for OS, and 0.466 (95% CI, 0.376-0.576; p < 0.0001) and 0.438 (95% CI, 0.298-0.644; P < 0.0001) for PFS. The triplet DCF regimen provides a high and significant benefit in OS and PFS over doublet regimens, and should be considered as upfront treatment for eligible patients with advanced SCCA.
RESUMEN
BACKGROUND: We hypothesized that perioperative FOLFOX (5-fluorouracil, leucovorin, oxaliplatin) might be used as an alternative to standard FLOT (docetaxel, 5-fluorouracil, leucovorin, and oxaliplatin) in patients with locally advanced oesogastric adenocarcinomas (OGA), particularly those with frailties. PATIENTS AND METHODS: We reviewed the charts of 61 consecutives patients treated with FOLFOX for resectable OGA to estimate overall survival, recurrence-free survival, and safety. RESULTS: The median follow-up was 69.7 (range=3.6-97.9) months. Few patients experienced grade 3 adverse events during the preoperative (n=6; 10%) and postoperative (n=6; 16%) phases. One patient experienced a fatal grade 5 adverse events (cardiogenic shock). Median overall survival was 51.7 months [95% confidence interval (CI)=31.6-93.2 months] and the 5-year survival rate was 44.4% (95% CI=30.3%-57.5%). CONCLUSION: Regarding its comparable efficacy and its favourable toxicity profile, perioperative FOLFOX is a reasonable alternative to FLOT for frail patients with resectable OGA.

BACKGROUND: Two-stage hepatectomy for bilobar colorectal cancer liver metastases is potentially curative for selected patients. Histological growth patterns of colorectal liver metastases (desmoplastic, replacement, and pushing) have prognostic value. Our aim was to evaluate their association with pathologic response to preoperative treatment, second-stage hepatectomy completion, and survival in patients treated with a curative-intent 2-stage hepatectomy. METHODS: In 67 patients planned for 2-stage hepatectomy, colorectal liver metastases resected from the first-stage hepatectomy were retrospectively evaluated for growth patterns and pathologic response according to Tumor Regression Grading, modified Tumor Regression Grading, and Blazer grading. Tumor Regression Grading 1 to 3, modified Tumor Regression Grading 1 to 3, and Blazer 0 and 1 defined good responders. RESULTS: Desmoplastic growth patterns (GP) were more frequent among good responders (P < .001). Second-stage hepatectomy completion was associated with desmoplastic growth patterns and pathologic response on univariate analysis and multivariable analyses (P = .017 and P = .041, respectively). Median follow-up was 84 months (95% confidence interval: 53.4 [not reached]). Nondesmoplastic GP patients and nonresponders had a poorer overall survival (hazard ratio = 3.86, 95% confidence interval: 2.11-7.07, P < .001 and hazard ratio = 2.14, 95% confidence interval: 1.19-3.83, P = .009, respectively) on univariate analysis. Nondesmoplastic growth pattern was the only factor associated with a poorer overall survival on multivariable analysis (hazard ratio = 4.17, 95% confidence interval: 1.79-9.74, P < .001). Nondesmoplastic GP was also associated with a poorer recurrence-free survival (hazard ratio = 2.05, 95% confidence interval: 1.13-3.70, P = .017). CONCLUSION: Desmoplastic GP could represent a useful morphological marker for early identification of patients who might benefit from 2-stage hepatectomy completion.

OBJECTIVE: The BEACON CRC randomised controlled trial (NCT02928224) in BRAF-mutant metastatic colorectal cancer (mCRC) patients showed improved overall survival for the combination treatment of encorafenib (BRAF inhibitor) with cetuximab (EGFR inhibitor) compared with cetuximab with chemotherapy (FOLFIRI (folinic acid, fluorouracil and irinotecan) or irinotecan). We aimed to evaluate the cost-effectiveness of encorafenib with cetuximab in adult patients with BRAF-mutant mCRC after prior systemic therapy, from the perspective of the French healthcare system. DESIGN: A partitioned survival analysis model was developed to assess the cost-effectiveness of encorafenib with cetuximab using data from BEACON CRC (encorafenib with cetuximab and cetuximab with FOLFIRI or irinotecan). For two further comparator treatments (FOLFIRI alone and bevacizumab with FOLFIRI), a systemic literature review identified appropriate clinical trial data for indirect comparison. Piecewise modelling extrapolation was used to fulfil a lifetime horizon in the model. A discount rate of 2.5% was used. Treatment-emergent adverse events ≥grade 3 with an incidence of ≥2% were included, as well as relative dose intensity and utility values. OUTCOME MEASURES: The effectiveness outcomes of the model were expressed in terms of incremental life years gained and incremental quality-adjusted life years (QALY) gained. The cost-effectiveness of encorafenib with cetuximab was assessed using the incremental cost-effectiveness ratio (ICER). Results were presented probabilistically to account for parametric uncertainty. Deterministic and scenario analyses were conducted. RESULTS: The ICER for encorafenib with cetuximab versus cetuximab with FOLFIRI or irinotecan, FOLFIRI alone and bevacizumab with FOLFIRI was 69 823/QALY, 70 421/QALY and 72 336/QALY, respectively. Encorafenib with cetuximab was considered cost-effective compared with the three comparators at a willingness to pay threshold of 90 000/QALY, with probabilities of being cost-effective of 89.8%, 98.2% and 86.4%, respectively. CONCLUSIONS: This analysis showed encorafenib with cetuximab to be a cost-effective treatment in mCRC patients with a BRAF V600E mutation.

INTRODUCTION: Approval of sunitinib and everolimus for the treatment of progressive, unresectable or metastatic well-differentiated pancreatic neuroendocrine tumors (pNETs) was obtained in France in 2011 and 2012, respectively. OPALINE was set up as an observational study to evaluate the efficacy of sunitinib and everolimus compared to usual pNET treatments of chemotherapies and somatostatin analogues that had been previously recommended by the health authorities. METHODS: The OPALINE study assessed the efficacy of everolimus and sunitinib in terms of survival, disease progression and tolerance. Patients (N = 144) were enrolled from May 2015 to September 2017, and their disease characteristics were analyzed from diagnosis to 2 years post-enrollment. RESULTS: At inclusion most patients had comorbidities, and about 95% presented metastases. Patients received on average 3.2 lines of treatment from diagnosis to inclusion and two lines throughout the 2-year follow-up. Seventy-nine patients (59.0%) received at least one targeted therapy (TT) during their care path. For these patients, the overall survival (OS) was approximatively 176.5 months (95% CI: 97.2-not evaluable), with a 2-year survival rate estimated at 93.6% (SD 2.6%). Similar survival rates were observed whether the TTs were prescribed sooner or later in the treatment path. The main reasons for discontinuation of TTs were disease progression (54 patients) and adverse events (26 patients). Most patients receiving TTs did not change their dose during the follow-up reflecting the good treatment tolerability over time. No new safety alert was reported for everolimus and sunitinib during this study. CONCLUSION: Given their good tolerance and positive impact on estimated OS, the two TTs have an important role to play in the care path of patients with pNETs.

Introduction: Stereotactic MR-guided Adaptive RadioTherapy (SMART) is a novel process to treat pancreatic tumors. We present an update of the data from our prospective registry of SMART for pancreatic tumors. Materials and methods: After the establishment of the SMART indication in a multidisciplinary board, we included all patients treated for pancreatic tumors. Primary endpoints were acute and late toxicities. Secondary endpoints were survival outcomes (local control, overall survival, distant metastasis free survival) and dosimetric advantages of adaptive process on targets volumes and OAR. Results: We included seventy consecutive patients in our cohort between October 2019 and April 2022. The prescribed dose was 50 Gy in 5 consecutive fractions. No severe acute SMART related toxicity was noted. Acute and late Grade ≤ 2 gastro intestinal were low. Daily adaptation significantly improved PTV and GTV coverage as well as OAR sparing. With a median follow-up of 10.8 months since SMART completion, the median OS, 6-months OS, and 1-year OS were 20.9 months, 86.7% (95% CI: (75−93%), and 68.6% (95% CI: (53−80%), respectively, from SMART completion. Local control at 6 months, 1 year, and 2 years were, respectively, 96.8 % (95% CI: 88−99%), 86.5 (95% CI: 68−95%), and 80.7% (95% CI: 59−92%). There was no grade > 2 late toxicities. Locally Advanced Pancreatic Cancers (LAPC) and Borderline Resectable Pancreatic Cancers (BRPC) patients (52 patients) had a median OS, 6-months OS, and 1-year OS from SMART completion of 15.2 months, 84.4% (95% CI: (70−92%)), and 60.5% (95% CI: (42−75%)), respectively. The median OS, 1-year OS, and 2-year OS from initiation of induction chemotherapy were 22.3 months, 91% (95% CI: (78−97%)), and 45.8% (95% CI: (27−63%)), respectively. Twenty patients underwent surgical resection (38.7 % of patients with initially LAPC) with negative margins (R0). Conclusion: To our knowledge, this is the largest series of SMART for pancreatic tumors. The treatment was well tolerated with only low-grade toxicities. Long-term OS and LC rates were achieved. SMART achieved high secondary resection rates in LAPC patients.
