Treatment of patients with BRAF V600E-mutated metastatic colorectal cancer after progression to encorafenib and cetuximab: data from a real-world nationwide dataset. ESMO Open 2024; 9:102996. [PMID: 38613911 PMCID: PMC11024565 DOI: 10.1016/j.esmoop.2024.102996] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Revised: 03/13/2024] [Accepted: 03/14/2024] [Indexed: 04/15/2024] Open
Abstract
BACKGROUND Targeted therapy (TT) with encorafenib and cetuximab is the current standard for patients with BRAFV600E-mutated metastatic colorectal cancer (mCRC) who received one or more prior systemic treatments. However, the median progression-free survival (mPFS) is ∼4 months, and little is known about the possibility of administering subsequent therapies, their efficacy, and clinicopathological determinants of outcome. METHODS A real-world dataset including patients with BRAFV600E-mutated mCRC treated with TT at 21 Italian centers was retrospectively interrogated. We assessed treatments after progression, attrition rates, and outcomes. RESULTS Of the 179 patients included, 85 (47%), 32 (18%), and 7 (4%) received one, two, or three lines of treatment after TT, respectively. Those receiving TT in the second line were more likely to receive at least one subsequent therapy (53%), as compared with those treated with TT in the third line or beyond (30%; P < 0.0001), and achieved longer postprogression survival (PPS), also in a multivariate model (P = 0.0001). Among 62 patients with proficient mismatch repair/microsatellite stable (pMMR/MSS) tumors receiving one or more lines of treatment after second-line TT, combinatory chemotherapy ± anti-vascular endothelial growth factor (anti-VEGF) was associated with longer PFS and PPS as compared with trifluridine-tipiracil or regorafenib (mPFS: 2.6 versus 2.0 months, P = 0.07; PPS: 6.5 versus 4.4 months, P = 0.04). CONCLUSIONS Our real-world data suggest that TT should be initiated as soon as possible after the failure of first-line treatment in BRAFV600E-mutated mCRC. Among patients with pMMR/MSS tumors, combinatory chemotherapy ± anti-VEGF appears the preferred treatment choice after TT failure.

Phase II study of capecitabine-based concomitant chemoradiation followed by durvalumab as a neoadjuvant strategy in locally advanced rectal cancer: the PANDORA trial. ESMO Open 2023; 8:101824. [PMID: 37774508 PMCID: PMC10594026 DOI: 10.1016/j.esmoop.2023.101824] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Revised: 08/17/2023] [Accepted: 08/19/2023] [Indexed: 10/01/2023] Open
Abstract
BACKGROUND This study investigated the efficacy of chemoradiotherapy (CRT) followed by durvalumab as neoadjuvant therapy of locally advanced rectal cancer. PATIENTS AND METHODS The PANDORA trial is a prospective, phase II, open-label, single-arm, multicenter study aimed at evaluating the efficacy and safety of preoperative treatment with durvalumab (1500 mg every 4 weeks for three administrations) following long-course radiotherapy (RT) plus concomitant capecitabine (5040 cGy RT in 25-28 fractions over 5 weeks and capecitabine administered at 825 mg/m2 twice daily). The primary endpoint was the pathological complete response (pCR) rate; secondary endpoints were the proportion of clinical complete remissions and safety. The sample size was estimated assuming a null pCR proportion of 0.15 and an alternative pCR proportion of 0.30 (α = 0.05, power = 0.80). The proposed treatment could be considered promising if ≥13 pCRs were observed in 55 patients (EudraCT: 2018-004758-39; NCT04083365). RESULTS Between November 2019 and August 2021, 60 patients were accrued, of which 55 were assessable for the study's objectives. Two patients experienced disease progression during treatment. Nineteen out of 55 eligible patients achieved a pCR (34.5%, 95% confidence interval 22.2% to 48.6%). Regarding toxicity related to durvalumab, grade 3 adverse events (AEs) occurred in four patients (7.3%) (diarrhea, skin toxicity, transaminase increase, lipase increase, and pancolitis). Grade 4 toxicity was not observed. In 20 patients (36.4%), grade 1-2 AEs related to durvalumab were observed. The most common were endocrine toxicity (hyper/hypothyroidism), dermatologic toxicity (skin rash), and gastrointestinal toxicity (transaminase increase, nausea, diarrhea, constipation). CONCLUSION This study met its primary endpoint showing that CRT followed by durvalumab could increase pCR with a safe toxicity profile. This combination is a promising, feasible strategy worthy of further investigation.

Encorafenib plus cetuximab with or without binimetinib in patients with BRAF V600E-mutated metastatic colorectal cancer: real-life data from an Italian multicenter experience. ESMO Open 2022; 7:100506. [PMID: 35696748 PMCID: PMC9271503 DOI: 10.1016/j.esmoop.2022.100506] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2022] [Revised: 04/03/2022] [Accepted: 04/06/2022] [Indexed: 11/15/2022] Open
Abstract
Background Encorafenib plus cetuximab with or without binimetinib showed increased objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) compared with chemotherapy plus anti-EGFR in previously treated patients with BRAF V600E-mutated (mut) metastatic colorectal cancer (mCRC). Although no formal comparison was planned, addition of binimetinib to encorafenib plus cetuximab did not provide significant efficacy advantage. Patients and methods This real-life study was aimed at evaluating safety, activity, and efficacy of encorafenib plus cetuximab with or without binimetinib in patients with BRAF V600E-mut mCRC treated at 21 Italian centers within a nominal use program launched in May 2019. Results Out of 133 patients included, 97 (73%) received encorafenib plus cetuximab (targeted doublet) and 36 (27%) the same therapy plus binimetinib (targeted triplet). Most patients had Eastern Cooperative Group Performance Status (ECOG-PS) of 0 or 1 (86%), right-sided primary tumor (69%), and synchronous disease (66%). Twenty (15%) tumors were DNA mismatch repair deficiency (dMMR)/microsatellite instability (MSI)-high. As many as 44 (34%) patients had received two or more prior lines of therapy, 122 (92%) were previously exposed to oxaliplatin, and 109 (82%) to anti-vascular endothelial growth factor (anti-VEGF). Most frequent adverse events were asthenia (62%) and anti-EGFR-related skin rash (52%). Any grade nausea (P = 0.03), vomiting (P = 0.04), and diarrhea (P = 0.07) were more frequent with the triplet therapy, while melanocytic nevi were less common (P = 0.06). Overall, ORR and disease control rate (DCR) were 23% and 69%, respectively, with numerically higher rates in the triplet group (ORR 31% versus 17%, P = 0.12; DCR 78% versus 65%, P = 0.23). Median PFS and OS were 4.5 and 7.2 months, respectively. Worse ECOG-PS, peritoneal metastases, and more than one prior treatment were independent poor prognostic factors for PFS and OS. Clonality of BRAF mutation measured as adjusted mutant allele fraction in tumor tissue was not associated with clinical outcome. Conclusions Our real-life data are consistent with those from the BEACON trial in terms of safety, activity, and efficacy. Patients in good general condition and not heavily pretreated are those more likely to derive benefit from the targeted treatment. Encorafenib plus cetuximab ± binimetinib is safe and effective for BRAF V600E mut mCRC even in the real-world setting. Median OS is slightly shorter than in the BEACON trial, probably due to less selected patients in real life. Patients deriving more benefit from targeted therapy are likely those in good general conditions and not heavily pretreated. BRAF adjusted MAF is worth further investigation to better characterize the genomic heterogeneity of BRAF V600E mut mCRC.

Abstract
BACKGROUND The phase III TRIBE and TRIBE2 studies randomized metastatic colorectal cancer patients to first-line FOLFOXIRI/bevacizumab or a doublet (FOLFIRI or FOLFOX)/bevacizumab. The studies demonstrated a significant benefit from the triplet at the price of an increased incidence of chemotherapy-related adverse events (AEs). In both trials, males and females aged between 18 and 70 years with ECOG PS ≤2 and between 71 and 75 years with ECOG PS = 0 were eligible. We investigated the effect of FOLFOXIRI/bevacizumab versus doublets/bevacizumab according to age and gender. PATIENTS AND METHODS Subgroup analyses according to age (<70 versus 70-75 years) and gender were carried out for overall response rate (ORR), progression-free survival (PFS), and AE rates. RESULTS Of 1187 patients, 1005 (85%) were aged <70 years and 182 (15%) 70-75 years; 693 (58%) were males and 494 (42%) females. There was no evidence of interaction between age or gender and the benefit provided by the intensification of the upfront chemotherapy in terms of ORR and PFS, or the increased risk of experiencing G3/4 AEs. Elderly patients and females experienced higher rates of overall G3/4 AEs (73% versus 60%, P < 0.01 and 69% versus 57%, P < 0.01, respectively). Notably, in the FOLFOXIRI/bevacizumab subgroup, G3/4 diarrhea and febrile neutropenia occurred in 27% and 16% of elderly patients, respectively, while females reported high incidences of any grade nausea (67%) and vomiting (50%). CONCLUSIONS The improvements in terms of ORR and PFS of FOLFOXIRI/bevacizumab versus doublets/bevacizumab are independent of gender and age, with a similar relative increase in AEs among elderly patients and females. Initial dose reductions and possibly primary G-CSF prophylaxis should be recommended for patients between 70 and 75 years old treated with FOLFOXIRI/bevacizumab, and a careful management of antiemetic prophylaxis should be considered among females.

Abstract
The incidence of squamous cell carcinoma of the anal canal (SCAC) is increasing in both sexes but the standard treatment remains that of 20 years ago. However, interesting data have recently emerged on the use of anti-epidermal growth factor receptor (EGFR) agents and immunotherapy in advanced disease. Thus, new avenues of research are opening up that will hopefully lead to more effective therapeutic strategies. We provide an overview of the latest studies published on this tumor and discuss the possible future therapeutic options for combination therapy, anti-EGFR treatment and radiotherapy.

Abstract
BACKGROUND We report the results from a first-line phase III randomized clinical trial on metastatic colorectal cancer (mCRC) aimed at evaluating the effectiveness of adding bevacizumab (B) to standard first-line chemotherapy (CT). PATIENTS AND METHODS mCRC patients were randomized to receive first-line CT (FOLFIRI or FOLFOX4) plus B (arm A) or CT only (arm B). The primary end point was progression-free survival (PFS). Secondary end points included overall survival (OS), response rate (ORR) and safety. Three hundred and fifty patients and 310 events were required to have an 80% statistical power to detect a difference in PFS between the groups. RESULTS Between November 2007 and March 2012, 376 patients were randomized. About 60% of patients received FOLFOX4 and 40% FOLFIRI. After a median follow-up of 36 months, 343 progressions and 275 deaths had been observed in the overall population. The median PFS was 9.6 [95% confidence interval (CI) 8.2-10.3] and 8.4 (95% CI 7.2-9.0) months for arms A and B, respectively, with a hazard ratio of 0.86 (95% CI 0.70-1.07; P = 0.182). No statistically significant differences in OS or ORR were observed. B-containing regimens were associated with more frequent hypertension, bleeding, proteinuria and asthenia. CONCLUSIONS The addition of B to standard first-line CT for mCRC did not provide a benefit in terms of PFS, OS or ORR. Further research is warranted to better identify the target population.

Abstract
OBJECTIVE Taxanes and fluoropyrimidines are active in metastatic breast cancer (MBC), and their combination has proven effective in anthracycline-refractory patients. We conducted a phase I study to determine the maximum tolerated dose (MTD) of uracil plus tegafur (UFT) given in combination with leucovorin (LV) and paclitaxel (Pacl) in patients with refractory MBC. METHODS Pacl was infused at a fixed dose of 150 mg/m2 on day 1. UFT, at doses escalated by 50 mg/m2 starting from 200 mg/m2 . day, and LV, at a fixed dose of 90 mg/day, were given orally every 8 h for 11 days (days 3-13). Cohorts of at least 3 patients were treated at each dose level, and if 1 experienced dose-limiting toxicity (DLT), a maximum of 3 additional patients were added at the same dose level. MTD was reached if 2 out of the 6 patients experienced DLT. RESULTS Sixteen patients were enrolled in the study. The most important toxicity observed was hematological. Nonhematological toxicities were paresthesia and myalgia, asthenia, nausea, and mucositis. DLT occurred in only 1 patient (grade 3 hepatic toxicity). CONCLUSIONS The recommended dose for a subsequent phase II trial is Pacl 150 mg/m2 on day 1, and UFT 300 mg/m2 and LV 90 mg on days 3-13, every 2 weeks.

10726 Background: IA infusion of CT increases drug concentrations within a tumor. We investigated if it is effective in BC patients (pts) with locally advanced disease or liver metastases. Methods: Twenty-five pts were treated with IA CT using angiographic technique in the Department of Medical Oncology, Morgagni-Pierantoni Hospital in Forlì. Pts received a short IA infusion through the proper hepatic artery (liver metastases) or the internal mammary artery (locally advanced disease). Drugs were: Epirubicin (EPI) 30 mg/m2, Mitomycin-c (MMC) 7 mg/m2 and 5-fluoruracil (5FU) 1000 mg on day 1 every 21 days. EPI was not administered in anthracycline pretreated pts. Results: Median age was 54.3 years (31–75 years) and ECOG Performance Status (PS) was ≤2. Nine pts had liver metastases and 16 had locally advanced disease. Twenty-three (96%) of the 25 pts had received adjuvant treatment (21 CT, 7 endocrine therapy), 20 (80%) had had at least one treatment for metastatic disease (20 CT, 11 endocrine therapy, 8 radiotherapy), and 11 pts (40%) had received concomitant therapy (3 CT and 8 endocrine). Fifteen pts were anthracycline-naïve. A total of 88 angiographic sessions were carried out, with a median number of 3.5 cycles per patient (1–8 cycles). One transitory ischaemic attack occurred during angiographic procedure . No other serious complications were observed. The only cases of toxicity higher than grade 2 were one grade III neutropenia and one grade IV thrombocytopenia. A dose reduction was necessary in 4 pts (2 due to PS, 1 to toxicity and 1 to pre-treatment) and treatment was interrupted in 4 pts (2 due to PS, 1 to early progression and 1 to technical problems). Among the 19 pts assessable for response, 13 (68%) had a partial response, 2 (11%) showed stable disease and 4 (21%) progressed. Median time to progression and median overall survival will be given. Conclusions: Our results suggest that IA CT may play a role in the treatment of advanced pre-treated BC pts. No significant financial relationships to disclose.

Abstract
The aim was to investigate whether intra-arterial infusion of chemotherapy improves response to treatment in unresectable liver metastases from colorectal cancer. We treated 14 patients (pts) with intra-arterial chemotherapy. Arterial catheters were placed via percutaneous access. Treatment schedule was: 5-FU and mitomycin-C on day 1 every 21 days. Six pts also received from day 3 for 5 days, a continuous intra-arterial 24-hr infusion of interleukin-2 (IL-2). We had only one case of toxicity drug-related > grade 2 (neutropenia). We observed 2 partial response (PR) and 5 stable disease (SD). Median time to disease progression (TTP) and median survival (OS) were, respectively 4 and 15 months.

Abstract
AIMS Liver resection improves survival in selected patients with colorectal liver metastases. However, the majority of patients with colorectal liver metastases have an inoperable oncological disease. The aim is to investigate whether intra-arterial infusion of chemotherapy, improves response to treatment and may convert a selected group of patients with irresectable liver metastases into an operable state. MATERIALS AND METHODS Thirty-sex patients (pts) with inoperable hepatic metastases from colorectal cancer were treated with intra-arterial chemotherapy, by angiographic technique. All patients underwent a short 5-FU-based locoregional infusion and the 13 non pretreated patients also received systemic therapy. Evaluation of response was made by CT scan. RESULTS Total cycles administered angiographically: 132 (range, 1-11). There were no complications associated with the angiographic procedure and no cases of > grade 2 toxicity. One heavily pretreated pt experienced moderate cholangitis and superficial gastric erosion. Thirty-one pts were assessable (20 pretreated and 11 not); there was 1 complete response (CR), 3 partial remissions (PR), 2 stabilizations (SD) among non-pretreated pts (6/11; CR + PR + SD = 55%) and 1 PR and 8 SD among pretreated pts (9/20; PR + SD = 45%). The remaining 16 pts progressed. Four pts became eligible for radical hepatic resection (1 refused surgery and 3 patients were operated on). There was no peri-operative deaths. Median survival of these 3 pts was 24, 28 and 39+ months. CONCLUSIONS Our data, even if based on a relatively small case series, appear to confirm effective local disease control in this clinical setting. Regional chemotherapy used singly or in combination with systemic chemotherapy may convert a selected group of patients with irresectable liver metastases to an oncological disease that can benefit from surgical treatment.
