Perioperative FLOT (fluorouracil, oxaliplatin, and docetaxel) triplet chemotherapy is the standard of care for localised and resectable gastric and gastro-oesophageal junction adenocarcinoma. We aimed to compare a modified FLOT regimen (also known as TFOX) with FOLFOX as first-line treatment for patients with HER2-negative advanced gastric and gastro-oesophageal junction adenocarcinoma. PRODIGE 51-FFCD-GASTFOX is an open-label, multicentre, randomised, phase 3 trial conducted at 96 medical centres in France. Eligible individuals were aged 18 years or older, had histologically confirmed, HER2-negative adenocarcinoma of the stomach or gastro-oesophageal junction that was locally advanced unresectable or metastatic and previously untreated, measurable disease per Response Evaluation Criteria in Solid Tumours, an Eastern Cooperative Oncology Group performance status of 0 or 1, and adequate organ function. Patients were randomly assigned (1:1), using the minimisation method, to receive FOLFOX (folinic acid 400 mg/m2, oxaliplatin 85 mg/m2, and 5-fluorouracil bolus 400 mg/m2 then 5-fluorouracil 2400 mg/m2 as a continuous 46 h infusion every 2 weeks) or TFOX (docetaxel 50 mg/m2, folinic acid 400 mg/m2, and oxaliplatin 85 mg/m2 then 5-fluorouracil 2400 mg/m2 as a continuous 46 h infusion every 2 weeks). Randomisation was stratified by centre, ECOG performance status, (neo)adjuvant chemotherapy or chemoradiotherapy, tumour stage, tumour location, and pathological histological subtype. The primary endpoint was progression-free survival (assessed in the intention-to-treat population), defined as time from randomisation to the first radiological or clinical progression (or both), or death due to any cause, whichever occurred first. Secondary endpoints included overall survival (defined as time from randomisation to death due to any cause) and objective response rate (defined as the proportion of patients with a best overall complete or partial response). Hazard ratio and 95% CIs were estimated using an unstratified Cox proportional hazards model. When the proportional hazards assumption was violated, the restricted mean survival time was used to estimate the treatment effect size. This study is registered with ClinicalTrials.gov, NCT03006432, and EudraCT, 2016–002331–16. Between Dec 19, 2016, and Dec 26, 2022, 507 patients were randomly assigned (254 to the TFOX group and 253 to the FOLFOX group [intention-to-treat population]). The median age was 64·2 years (IQR 56·7–70·8), and 399 (79%) participants were male and 108 (21%) were female. At median follow-up of 42·8 months (25·8–49·9), the median progression-free survival was 7·59 months (95% CI 7·06–7·95) in the TFOX group versus 5·98 months (5·65–6·97) in the FOLFOX group. The assumption of proportional hazards was violated (p=0·013); therefore, the 12-month restricted mean progression-free survival was calculated: 7·52 months (7·06–7·97) in the TFOX group versus 6·62 months (6·16–7·09) in the FOLFOX group (p=0·0072). The median overall survival was 15·08 months (13·70–16·72) in the TFOX group versus 12·65 months (10·94–14·00) in the FOLFOX group (proportional hazards assumption was confirmed; HR 0·82 [0·68–0·99]; p=0·048) and the objective response rate was 62·3% (56·0–68·3) versus 53·4% (47·0–59·8; p=0·045). The most common grade 3 and 4 treatment-emergent adverse events were diarrhoea (37 [15%] in the TFOX group vs 18 [7%] in the FOLFOX group), peripheral neuropathy (80 [32%] vs 49 [20%]), neutropenia (67 [27%] vs 44 [18%]), and fatigue (40 [16%] vs 20 [8%]). Serious treatment-related adverse events occurred in 66 (27%) participants in the TFOX group and 33 (13%) in the FOLFOX group. There were two (<1%) treatment-related deaths in the TFOX group (one due to septic shock and one due to gastrointestinal perforation) and one (<1%) in the FOLFOX group (due to septic shock). The modified FLOT/TFOX regimen significantly improved progression-free survival, overall survival, and objective response rate compared with FOLFOX in previously untreated patients with advanced HER2-negative gastric and gastro-oesophageal junction adenocarcinoma. The modified FLOT/TFOX regimen might represent a new first-line treatment option for patients eligible for this docetaxel triplet chemotherapy. Fédération Francophone de Cancérologie Digestive.

Treatment of locally advanced rectal cancer with chemoradiotherapy, surgery, and adjuvant chemotherapy controls local disease, but distant metastases remain common. We aimed to assess whether administering neoadjuvant chemotherapy before preoperative chemoradiotherapy could reduce the risk of distant recurrences. We did a phase 3, open-label, multicentre, randomised trial at 35 hospitals in France. Eligible patients were adults aged 18–75 years and had newly diagnosed, biopsy-proven, rectal adenocarcinoma staged cT3 or cT4 M0, with a WHO performance status of 0–1. Patients were randomly assigned (1:1) to either the neoadjuvant chemotherapy group or standard-of-care group, using an independent web-based system by minimisation method stratified by centre, extramural extension of the tumour into perirectal fat according to MRI, tumour location, and stage. Investigators and participants were not masked to treatment allocation. The neoadjuvant chemotherapy group received neoadjuvant chemotherapy with FOLFIRINOX (oxaliplatin 85 mg/m2, irinotecan 180 mg/m2, leucovorin 400 mg/m2, and fluorouracil 2400 mg/m2 intravenously every 14 days for 6 cycles), chemoradiotherapy (50 Gy during 5 weeks and 800 mg/m2 concurrent oral capecitabine twice daily for 5 days per week), total mesorectal excision, and adjuvant chemotherapy (3 months of modified FOLFOX6 [intravenous oxaliplatin 85 mg/m2 and leucovorin 400 mg/m2, followed by intravenous 400 mg/m2 fluorouracil bolus and then continuous infusion at a dose of 2400 mg/m2 over 46 h every 14 days for six cycles] or capecitabine [1250 mg/m2 orally twice daily on days 1–14 every 21 days]). The standard-of-care group received chemoradiotherapy, total mesorectal excision, and adjuvant chemotherapy (for 6 months). The primary endpoint was disease-free survival assessed in the intention-to-treat population at 3 years. Safety analyses were done on treated patients. This trial was registered with EudraCT (2011-004406-25) and ClinicalTrials.gov (NCT01804790) and is now complete. Between June 5, 2012, and June 26, 2017, 461 patients were randomly assigned to either the neoadjuvant chemotherapy group (n=231) or the standard-of-care group (n=230). At a median follow-up of 46·5 months (IQR 35·4–61·6), 3-year disease-free survival rates were 76% (95% CI 69–81) in the neoadjuvant chemotherapy group and 69% (62–74) in the standard-of-care group (stratified hazard ratio 0·69, 95% CI 0·49–0·97; p=0·034). During neoadjuvant chemotherapy, the most common grade 3–4 adverse events were neutropenia (38 [17%] of 225 patients) and diarrhoea (25 [11%] of 226). During chemoradiotherapy, the most common grade 3–4 adverse event was lymphopenia (59 [28%] of 212 in the neoadjuvant chemotherapy group vs 67 [30%] of 226 patients in the standard-of-care group). During adjuvant chemotherapy, the most common grade 3–4 adverse events were lymphopenia (18 [11%] of 161 in the neoadjuvant chemotherapy group vs 42 [27%] of 155 in the standard-of-care group), neutropenia (nine [6%] of 161 vs 28 [18%] of 155), and peripheral sensory neuropathy (19 [12%] of 162 vs 32 [21%] of 155). Serious adverse events occurred in 63 (27%) of 231 participants in the neoadjuvant chemotherapy group and 50 (22%) of 230 patients in the standard-of-care group (p=0·167), during the whole treatment period. During adjuvant therapy, serious adverse events occurred in 18 (11%) of 163 participants in the neoadjuvant chemotherapy group and 36 (23%) of 158 patients in the standard-of-care group (p=0·0049). Treatment-related deaths occurred in one (<1%) of 226 patients in the neoadjuvant chemotherapy group (sudden death) and two (1%) of 227 patients in the standard-of-care group (one sudden death and one myocardial infarction). Intensification of chemotherapy using FOLFIRINOX before preoperative chemoradiotherapy significantly improved outcomes compared with preoperative chemoradiotherapy in patients with cT3 or cT4 M0 rectal cancer. The significantly improved disease-free survival in the neoadjuvant chemotherapy group and the decreased neurotoxicity indicates that the perioperative approach is more efficient and better tolerated than adjuvant chemotherapy. Therefore, the PRODIGE 23 results might change clinical practice. Institut National du Cancer, Ligue Nationale Contre le Cancer, and R&D Unicancer.

Pancreatic ductal adenocarcinoma remains one of the most lethal malignancies, with few treatment options. NAPOLI 3 aimed to compare the efficacy and safety of NALIRIFOX versus nab-paclitaxel and gemcitabine as first-line therapy for metastatic pancreatic ductal adenocarcinoma (mPDAC). NAPOLI 3 was a randomised, open-label, phase 3 study conducted at 187 community and academic sites in 18 countries worldwide across Europe, North America, South America, Asia, and Australia. Patients with mPDAC and Eastern Cooperative Oncology Group performance status score 0 or 1 were randomly assigned (1:1) to receive NALIRIFOX (liposomal irinotecan 50 mg/m2, oxaliplatin 60 mg/m2, leucovorin 400 mg/m2, and fluorouracil 2400 mg/m2, administered sequentially as a continuous intravenous infusion over 46 h) on days 1 and 15 of a 28-day cycle or nab-paclitaxel 125 mg/m2 and gemcitabine 1000 mg/m2, administered intravenously, on days 1, 8, and 15 of a 28-day cycle. Balanced block randomisation was stratified by geographical region, performance status, and liver metastases, managed through an interactive web response system. The primary endpoint was overall survival in the intention-to-treat population, evaluated when at least 543 events were observed across the two treatment groups. Safety was evaluated in all patients who received at least one dose of study treatment. This completed trial is registered with ClinicalTrials.gov, NCT04083235. Between Feb 19, 2020 and Aug 17, 2021, 770 patients were randomly assigned (NALIRIFOX, 383; nab-paclitaxel–gemcitabine, 387; median follow-up 16·1 months [IQR 13·4–19·1]). Median overall survival was 11·1 months (95% CI 10·0–12·1) with NALIRIFOX versus 9·2 months (8·3–10·6) with nab-paclitaxel–gemcitabine (hazard ratio 0·83; 95% CI 0·70–0·99; p=0·036). Grade 3 or higher treatment-emergent adverse events occurred in 322 (87%) of 370 patients receiving NALIRIFOX and 326 (86%) of 379 patients receiving nab-paclitaxel–gemcitabine; treatment-related deaths occurred in six (2%) patients in the NALIRIFOX group and eight (2%) patients in the nab-paclitaxel–gemcitabine group. Our findings support use of the NALIRIFOX regimen as a possible reference regimen for first-line treatment of mPDAC. Ipsen. For the plain language summary see Supplementary Materials section.

Medullary thyroid cancer often develops in patients with somatic or germline mutations in RET . Selpercatinib is a novel RET inhibitor. In a phase 1–2 trial, a response to selpercatinib occurred in 38 of 55 previously treated patients (69%) and in 64 of 88 previously untreated patients (73%). Toxic effects were mainly low grade.

In this large international study of patients with adrenal cancer, a rare, treatment-refractory disease, mitotane plus a combination of etoposide, cisplatin, and doxorubicin had greater antitumor activity than mitotane plus streptozotocin. Adrenocortical carcinoma is a rare cancer (estimated incidence, 0.7 to 2.0 cases per 1 million population per year) 1 , 2 with a poor prognosis; the 5-year survival rate is less than 15% among patients with metastatic disease. 3 – 7 Mitotane is the only drug approved for the treatment of adrenocortical carcinoma and is used both as adjuvant therapy and for advanced disease, 8 – 14 although its efficacy has never been shown in a randomized trial. The experience with other antineoplastic drugs for the treatment of this disease is even more limited. Current treatment strategies for advanced disease are based exclusively on retrospective series . . .

No randomised controlled trial has ever been done in patients with metastatic phaeochromocytomas and paragangliomas. Preclinical and first clinical evidence suggested beneficial effects of sunitinib. We aimed to evaluate the safety and efficacy of sunitinib in patients with metastatic phaeochromocytomas and paragangliomas. FIRSTMAPPP is a multicentre, international, randomised, placebo-controlled, double-blind, phase 2 trial done at 14 academic centres across four European countries. Eligible participants were adults (aged ≥18 years) with sporadic or inherited progressive metastatic phaeochromocytomas and paragangliomas. Patients were randomly assigned (1:1) to receive either oral sunitinib (37·5 mg per day) or placebo. Randomisation was stratified according to SDHB status (mutation present vs wild type) and number of previous systemic therapies (0 vs ≥1). Primary endpoint was the rate of progression-free survival at 12 months according to real-time central review (Response Evaluation Criteria in Solid Tumours version 1.1). On the basis of a two-step Simon model, we aimed for the accrual of 78 patients, assuming a 20% improvement of the 12-month progression-free survival rate from 20% to 40%, to conclude that sunitinib is effective. Crossover from the placebo group was allowed. This trial is registered with ClinicalTrials.gov, number NCT01371201, and is closed for enrolment. From Dec 1, 2011, to Jan 31, 2019, a total of 78 patients with progressive metastatic phaeochromocytomas and paragangliomas were enrolled (39 patients per group). 25 (32%) of 78 patients had germline SDHx variants and 54 (69%) had used previous therapies. The primary endpoint was met, with a 12-month progression-free survival in 14 of 39 patients (36% [90% CI 23–50]) in the sunitinib group. In the placebo group, the 12-month progression-free survival in seven of 39 patients was 19% (90% CI 11–31), validating the hypotheses of our study design. The most frequent grade 3 or 4 adverse events were asthenia (seven [18%] of 39 and one [3%] of 39), hypertension (five [13%] and four [10%]), and back or bone pain (one [3%] and three [8%]) in the sunitinib and placebo groups, respectively. Three deaths occurred in the sunitinib group: these deaths were due to respiratory insufficiency, amyotrophic lateral sclerosis, and rectal bleeding. Only the latter event was considered drug related. Two deaths occurred in the placebo group due to aspiration pneumonia and septic shock. This first randomised trial supports the use of sunitinib as the medical option with the highest level of evidence for anti-tumour efficacy in progressive metastatic phaeochromocytomas and paragangliomas.

Gemcitabine plus a platinum-based agent (eg, cisplatin or oxaliplatin) is the standard of care for advanced biliary cancers. We investigated the addition of cetuximab to chemotherapy in patients with advanced biliary cancers. In this non-comparative, open-label, randomised phase 2 trial, we recruited patients with locally advanced (non-resectable) or metastatic cholangiocarcinoma, gallbladder carcinoma, or ampullary carcinoma and a WHO performance status of 0 or 1 from 18 hospitals across France and Germany. Eligible patients were randomly assigned (1:1) centrally with a minimisation procedure to first-line treatment with gemcitabine (1000 mg/m2) and oxaliplatin (100 mg/m2) with or without cetuximab (500 mg/m2), repeated every 2 weeks until disease progression or unacceptable toxicity. Randomisation was stratified by centre, primary site of disease, disease stage, and previous treatment with curative intent or adjuvant therapy. Investigators who assessed treatment response were not masked to group assignment. The primary endpoint was the proportion of patients who were progression-free at 4 months, analysed by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00552149. Between Oct 10, 2007, and Dec 18, 2009, 76 patients were assigned to chemotherapy plus cetuximab and 74 to chemotherapy alone. 48 (63%; 95% CI 52–74) patients assigned to chemotherapy plus cetuximab and 40 (54%; 43–65) assigned to chemotherapy alone were progression-free at 4 months. Median progression-free survival was 6·1 months (95% CI 5·1–7·6) in the chemotherapy plus cetuximab group and 5·5 months (3·7–6·6) in the chemotherapy alone group. Median overall survival was 11·0 months (9·1–13·7) in the chemotherapy plus cetuximab group and 12·4 months (8·6–16·0) in the chemotherapy alone group. The most common grade 3–4 adverse events were peripheral neuropathy (in 18 [24%] of 76 patients who received chemotherapy plus cetuximab vs ten [15%] of 68 who received chemotherapy alone), neutropenia (17 [22%] vs 11 [16%]), and increased aminotransferase concentrations (17 [22%] vs ten [15%]). 70 serious adverse events were reported in 39 (51%) of 76 patients who received chemotherapy plus cetuximab (34 events in 19 [25%] patients were treatment-related), whereas 41 serious adverse events were reported in 25 (35%) of 71 patients who received chemotherapy alone (20 events in 12 [17%] patients were treatment-related). One patient died of atypical pneumonia related to treatment in the chemotherapy alone group. The addition of cetuximab to gemcitabine and oxaliplatin did not seem to enhance the activity of chemotherapy in patients with advanced biliary cancer, although it was well tolerated. Gemcitabine and platinum-based combination should remain the standard treatment option. Institut National du Cancer, Merck Serono.

Primary malignant melanoma of the esophagus is rare, accounting for less than 0.1-0.2% of all esophageal malignancies. It is associated with a poor outcome due to late detection and high metastatic potential. Here, we report a case of esophageal cancer, which was initially diagnosed as an adenocarcinoma and finally was confirmed as a primary malignant melanoma. This 75-year-old Caucasian male had a history of dysphagia and recent lingering abdominal pain. First biopsy showed a poorly-differentiated adenocarcinoma. He was then treated with neoadjuvant radiochemotherapy. Biopsies were repeated because of an incomplete tumor response, evaluated by endoscopic and imaging studies. The final diagnosis was a malignant melanoma. The patient has been treated with immune-checkpoint inhibitor, nivolumab, an anti-PD1 antibody.

Regorafenib is an orally available multikinase inhibitor, currently approved in metastatic chemorefractory colorectal cancer patients. The results of two large randomized Phase III trials are available, providing significant results in overall and progression-free survival in this situation. Its use requires a special attention regarding patient selection, dosing schedule and management of adverse events. Identifying patients who will tolerate and have benefit from regorafenib is a challenge for clinicians. Therapeutic monitoring (especially cfDNA), predictive biomarkers and specific perfusion-based imaging techniques will may be result in optimizing regorafenib treatment.

BackgroundImmune checkpoint inhibitors (ICIs) are highly effective in patients with microsatellite instability/mismatch repair-deficient (MSI/dMMR) metastatic colorectal cancer (mCRC). Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria may underestimate response to ICIs due to the pseudoprogression phenomenon. The GERCOR NIPICOL phase II study aimed to evaluate the frequency of pseudoprogressions in patients with MSI/dMMR mCRC treated with nivolumab and ipilimumab.MethodsPatients with MSI/dMMR mCRC previously treated with fluoropyrimidines, oxaliplatin, and irinotecan with/without targeted therapies received nivolumab 3 mg/kg plus ipilimumab 1 mg/kg every 3 weeks for four cycles then nivolumab 3 mg/kg every 2 weeks until progression or a maximum of 20 cycles. Computed tomography scan tumor assessments were done every 6 weeks for 24 weeks and then every 12 weeks. The primary endpoint was disease control rate at 12 weeks according to RECIST 1.1 and iRECIST by central review.ResultsOf 57 patients included between December 2017 and November 2018, 48.0% received ≥3 prior lines of chemotherapy, 18.0% had BRAF V600E mutation, and 56.0% had Lynch syndrome-related cancer. Seven patients (12.0%) discontinued treatment due to adverse events; one died due to a treatment-related adverse event. The disease control rate (DCR) at 12 weeks was 86.0% with RECIST 1.1% and 87.7% with iRECIST. Two pseudoprogressions (3.5%) were observed, at week 6 and at week 36, representing 18% of patients with disease progression per RECIST 1.1 criteria. With a median follow-up of 18.4 months, median progression-free survival (PFS) and overall survival (OS) were not reached. The 12-month PFS rate was 72.9% with RECIST 1.1% and 76.5% with iRECIST. The 12-month OS rate was 84%. Overall response rate was 59.7% with both criteria. RAS/BRAF status, sidedness, Lynch syndrome, and other baseline parameters were not associated with PFS.ConclusionPseudoprogression is rare in patients with MSI/dMMR mCRC treated with nivolumab and ipilimumab. This combined ICI therapy confirms impressive DCR and survival outcomes in these patients.Trial registration number NCT03350126.
