ABSTRACT

Background: Patients with refractory metastatic colorectal cancer (mCRC) rarely receive third-line or further treatment. In this context, regorafenib (R) and trifluridine/tipiracil (T) are two important novel therapeutic choices with statistically significant increases in overall survival (OS), progression-free survival (PFS), and disease control, with different toxicity profiles. This study is a subgroup analysis of our larger retrospective study, already published, whose objective was to assess the outcomes of patients when R and T were given sequentially. Patients and Methods: The study involved thirteen Italian cancer centers on a 10-year retrospective observation (2012-2022). In this subgroup analysis, we focused our attention on the correlation between the first drug treatment duration (<3 months, 3 to <6 months and ≥6 months) and survival outcomes in patients who had received the sequence regorafenib-to-trifluridine/tipiracil, or vice versa. Results: The initial study included 866 patients with mCRC who received sequential T/R, or R/T, or T or R alone. This analysis is focused on evaluating the impact of the duration of the first treatment in the sequence on clinical outcomes (OS, PFS) and includes 146 and 116 patients of the T/R and R/T sequences, respectively. Based on the duration of the first drug treatment, subgroups for the T/R sequence included 27 patients (18.4%) who received T for <3 months, 86 (58.9%) treated for 3 to <6 months, and 33 (22.6%) treated for ≥6 months; in the reverse sequence (R as the first drug), subgroups included 18 patients (15.5%) who received their first treatment for <3 months, 62 (53.4%) treated for 3 to <6 months, and 35 (31.0%) treated for ≥6 months. In patients who received their first drug treatment for a period of 3 to <6 months, the R/T sequence had a significantly longer median OS (13.7 vs. 10.8 months, p = 0.0069) and a longer median PFS (10.8 vs. 8.5 months, p = 0.0003) than the T/R group. There were no statistically significant differences between groups with first drug treatment durations of <3 months and ≥6 months. Conclusions: Our analysis seems to suggest that the administration of R for a period of 3 to <6 months before that of T can prolong both OS and PFS, as compared to the opposite sequence.

ABSTRACT

BACKGROUND: Patients with refractory mCRC rarely undergo third-line or subsequent treatment. This strategy could negatively impact their survival. In this setting, regorafenib (R) and trifluridine/tipiracil (T) are two key new treatment options with statistically significant improvements in overall survival (OS), progression-free survival (PFS), and disease control with different tolerance profiles. This study aimed to retrospectively evaluate the efficacy and safety profiles of these agents in real-world practice. MATERIALS AND METHODS: In 2012-2022, 866 patients diagnosed with mCRC who received sequential R and T (T/R, n = 146; R/T, n = 116]) or T (n = 325]) or R (n = 279) only were retrospectively recruited from 13 Italian cancer institutes. RESULTS: The median OS is significantly longer in the R/T group (15.9 months) than in the T/R group (13.9 months) (p = 0.0194). The R/T sequence had a statistically significant advantage in the mPFS, which was 8.8 months with T/R vs. 11.2 months with R/T (p = 0.0005). We did not find significant differences in outcomes between groups receiving T or R only. A total of 582 grade 3/4 toxicities were recorded. The frequency of grade 3/4 hand-foot skin reactions was higher in the R/T sequence compared to the reverse sequence (37.3% vs. 7.4%) (p = 0.01), while grade 3/4 neutropenia was slightly lower in the R/T group than in the T/R group (66.2% vs. 78.2%) (p = 0.13). Toxicities in the non-sequential groups were similar and in line with previous studies. CONCLUSIONS: The R/T sequence resulted in a significantly longer OS and PFS and improved disease control compared with the reverse sequence. R and T given not sequentially have similar impacts on survival. More data are needed to define the best sequence and to explore the efficacy of sequential (T/R or R/T) treatment combined with molecular-targeted drugs.

ABSTRACT

BACKGROUND/AIM: Regorafenib (REG) and trifluridine/tipiracil (FTD/TPI) have have been shown to improve overall survival in patients with refractory metastatic colorectal cancer. The aim of our study was to evaluate the efficacy and safety profiles of these agents administered in sequence in real world practice. PATIENTS AND METHODS: Clinical data of patients treated beyond the 2°line with REG or FTD/TPI between January 2016 and August 2020, were retrospectively collected from eight institutes in the Lazio Region. RESULTS: We included 49 patients treated with both drug sequences. A total of 28 G3/G4 toxicity events (53.8%) were recorded in the FTD/TPI-to-REG sequence vs. 24 (46.1%) in the reverse sequence. Median overall survival for the patients included in the FTP/TPI-to-REG group was 20 months (95%CI=16.7-23.3) vs. 27 months in the reverse group (95%CI=17.8-36.2). The disease control rate was 45.0% for patients treated with the REG-to-FTD/TPI sequence vs. 24.1% in those treated with the FTD/TPI-to-REG sequence (p=0.18). CONCLUSION: The sequence REG-to-FTD/TPI and vice versa can extend survival, whereas only REG-to-FTD/TPI stabilizes cancer growth.

ABSTRACT

AIMS: BEAWARE investigated the pattern of first-line bevacizumab early interruption in the Italian real-world setting of metastatic colorectal cancer. METHODS: A total of 386 patients were followed for 15 months after first-line chemotherapy + bevacizumab start. The rate of bevacizumab interruption for progression or adverse drug reactions (ADRs) constituted the primary endpoint. RESULTS: A total of 78.2% of patients interrupted bevacizumab: 56.6% for progression, 7.3% for ADRs, and 36.1% for other reasons. Median treatment duration was 6.7, 2.5, and 4.6 months, respectively. Median progression-free survival was 10.3 months; however, 35.8% of patients were not progressed and were thus censored at the data cutoff of 15 months, while 21.8% were still receiving bevacizumab. Patients discontinuing for progression/ADRs more frequently had metastases in >1 site (p = .0001), and a shorter median progression-free survival (6.9 vs 13.9 months, p < .0001). CONCLUSIONS: In Italy, first-line bevacizumab is interrupted mainly for progression, only 7.3% due to adverse events, and about one third of cases for other reasons. In clinical practice, the attitude to treat until progression as per guidelines might be implemented. ClinicalTrials.gov Identifier: NCT01609075.

ABSTRACT

BACKGROUND: Alternating induction and maintenance phases is a common strategy in metastatic colorectal cancer (mCRC). Metronomic chemotherapy (metroCT) may represent a well-tolerated chemotherapy backbone for maximising bevacizumab effect during maintenance. The MOMA trial was designed to compare metroCT plus bevacizumab versus bevacizumab alone as maintenance following 4 months of induction with FOLFOXIRI plus bevacizumab. PATIENTS AND METHODS: In this phase II study, patients with unresectable mCRC were randomised to receive up to 8 cycles of FOLFOXIRI plus bevacizumab, followed by bevacizumab (arm A) or the same regimen followed by bevacizumab plus metroCT (capecitabine 500 mg/three times per day and cyclophosphamide 50 mg/die, arm B) until disease progression. The primary end-point was progression-free survival (PFS). According to the Rubinstein and Korn's design, to detect a hazard ratio[HR] of 0.75 favouring arm B, with 1 sided-alpha and beta errors of 15% and 80%, 173 events and 222 patients were required. RESULTS: Between May 2012 and March 2015, 232 patients, mostly with RAS (65%) or BRAF (9%) mutant tumours, were randomised in 16 Italian centres. At a median follow-up of 47.8 months, 210 and 164 progression and death events were registered. The primary end-point was not met. Median PFS was 10.3 and 9.4 months in arm B and A, respectively (HR: 0.94 [70% confidence interval {CI}: 0.82-1.09], p = 0.680). No significant differences were reported in terms of overall survival (OS) (median OS arm B/A: 22.5/28 months; HR: 1.16 [95%CI: 0.99-1.37], p = 0.336). Response rate with FOLFOXIRI plus bevacizumab was 63% (arm B/A: 58%/68%). In the liver-limited subgroup, the secondary resection rate was 49% (arm B/A: 45%/55%). CONCLUSIONS: The addition of metroCT to maintenance with bevacizumab does not significantly improve PFS of mCRC patients. The activity of FOLFOXIRI plus bevacizumab is confirmed in a population with high prevalence of RAS/BRAF mutations treated with a 4-months induction.

ABSTRACT

IMPORTANCE: The combination of a triple-drug chemotherapy regimen with an anti-epidermal growth factor receptor (EGFR) agent as a first-line treatment of metastatic colorectal cancer (mCRC) showed promising activity along with safety concerns in single-arm phase 2 trials. The role of maintenance following chemotherapy and anti-EGFR and the optimal regimen to be adopted are not established. OBJECTIVES: To evaluate the activity and safety of cetuximab plus modified FOLFOXIRI (mFOLFOXIRI) and explore the role of maintenance with cetuximab or bevacizumab in RAS and BRAF wild-type mCRC. DESIGN, SETTING, AND PARTICIPANTS: In a prospective, noncomparative, open-label, multicenter, randomized phase 2 trial, patients aged 18 to 75 years with unresectable, previously untreated RAS and BRAF wild-type (before amendment, KRAS wild-type) mCRC were recruited from 21 oncology units in Italy from October 19, 2011, to March 1, 2015 (followed up through May 31, 2017). In total, 323 patients were screened and 143 were randomized to 2 treatment arms to receive as a first-line induction a regimen of mFOLFOXIRI plus cetuximab followed by cetuximab (arm A) or bevacizumab (arm B) until disease progression. Primary analyses were conducted in a modified intention-to-treat population. INTERVENTIONS: mFOLFOXIRI plus cetuximab repeated every 2 weeks for up to 8 cycles, followed by maintenance with cetuximab or bevacizumab until disease progression. MAIN OUTCOMES AND MEASURES: The primary end point was the 10-month progression-free rate (PFR); secondary end points included progression-free and overall survival, response rate, rate of metastases resection, and adverse events. RESULTS: Of 143 patients randomized, 116 (81.1%) (median [interquartile range (IQR)] age, 59.5 [53-67] years; 34 [29.3%] women) had RAS and BRAF wild-type mCRC. At a median (IQR) follow-up of 44.0 (30.5-52.1) months, 10-month PFRs were 50.8% (90% CI, 39.5%-62.2%) in arm A and 40.4% (90% CI, 29.4%-52.1%) in arm B. The overall response rate was 71.6% (95% CI, 62.4%-79.5%). Main grade 3/4 adverse events were neutropenia (occurring in 36 patients [31%]), diarrhea (in 21 patients [18%]), skin toxic effects (in 18 patients [16%]), asthenia (in 11 patients [9%]), stomatitis (in 7 patients [6%]), and febrile neutropenia (in 3 patients [3%]). CONCLUSIONS AND RELEVANCE: Although neither of the 2 arms met the primary end point, the findings indicate that a 4-month induction regimen of mFOLFOXIRI plus cetuximab is feasible and provides relevant activity results, leading to a high surgical resection rate. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT02295930.

ABSTRACT

BACKGROUND: Colorectal cancer patients have a median age of incidence >65years although they are largely under-represented in phase-III trials. This large population contains patients unfit for treatment, those suitable for monotherapy or for doublets and the impact of chemotherapy outside clinical trial is unclear. The aim of the study was to retrospectively analyse Overall Survival(OS) of elderly metastatic colorectal cancer(mCRC) patients treated with chemotherapy in daily practice. METHODS: Kaplan-Meir method was used for OS, the log-rank or Tarone-Ware test for differences between subgroups, Cox's proportional hazard model to assess the impact of known prognostic factors and treatment. RESULTS: 751 patients with mCRC observed between January 2000 and January 2013 were collected. Median age was 79 year(75-93); Male/Female 61/39%, ECOG-PS 0-1/2 85/15%; colon/rectum 74/26%; multiple metastatic sites 34%, only liver metastasis in 41% of patients. KRAS status was studied in 35% of patients: 44% of them showed gene mutation. 20.5% of patients did not received any kind of treatment including surgery. Comorbidities observed: cardiovascular 34%, diabetes 14%, hypertension 50%. Primary tumor was resected in 80.6%; surgery of liver metastasis was done in 19% of patients (2.3% of patients >80years). 78% of patients underwent chemotherapy. Median follow up was 12 months(range 1-124). Median OS was 17 months (CI 95%15-19);median OS in no-treated patients was 5 months (4-6); mOS of patients with at least one treatment was 20 months (18-22). In KRAS mutated group median OS was 19months (15-23) while in KRAS wild type patients median OS was 25 months (20-30). At multivariate analysis sex(Female), age(<80y), performance status(0-1), chemotherapy, Surgery of metastasis, Surgery of primary tumor and Site of metastasis(liver) were prognostic factors for OS. CONCLUSION: The results of our study show that in clinical practice treatment has a positive impact on OS of elderly patients, confirmed at multivariate analysis, included patients with age >80 years old or with a poor performance status (respectively p<0.0001 and p<0.0001). KRAS analysis deserve further evaluation.

ABSTRACT

BACKGROUND: Adjuvant chemotherapy (AC) in Stage II Colon Cancer (CC) is still under debate. Choice should be based on patients and disease characteristics. According to guidelines AC should be considered in high-risk T3N0 patients. No data are available for better option in low-risk patients. The aim of the study is to retrospectively evaluate relapse-free survival (RFS) and disease-free survival (DFS) according to treatment received in T3N0 CC. METHODS: RFS and DFS are evaluated with Kaplan-Meier method. Multivariate Cox proportional hazard model was developed using stepwise regression, enter limit and remove limit were p = 0.10 and p = 0.15, respectively. RESULTS: 834 patients with T3N0 CC were recruited. Median age was 69 (29-93), M/F 463/371, 335 low-risk patients (40.2%), 387 high-risk (46.4%), 112 unknown (13.4%); 127 (15.2%) patients showed symptoms at diagnosis. Median sampled lymph nodes were 15 (1-76); 353 (42.3%) patients were treated with AC. Median follow up was 5 years (range 3-24). The 5-years RFS was 78.4% and the 5-years DFS was 76.7%. At multivariate analysis symptoms, lymph nodes, and adjuvant chemotherapy were prognostic factors for RFS. AC is prognostic factor for all endpoints. In low-risk group 5-years RFS was 87.3% in treated patients and 74.7% in non-treated patients (p 0.03); in high-risk group was respectively 82.7% and 71.4% (p 0.005). CONCLUSIONS: Data confirmed the role of known prognostic factors and suggest the relevance of adjuvant chemotherapy also in low-risk stage II T3N0 CC patients. However, the highest risk in low-risk subgroup should be identified to be submitted to AC.

ABSTRACT

UNLABELLED: Monoclonal antibodies bevacizumab and cetuximab both improve overall survival (OS), progression free survival (PFS) and overall response rate (ORR) when combined with irinotecan-containing regimens. The optimal sequence of these monoclonal antibodies in combination with chemotherapy is controversial. This study analysed the efficacy of cetuximab plus Folfiri after progression with the same regimen plus bevacizumab in patients with metastatic colorectal cancer (mCRC). Patients are eligible if progressive disease (PD) after Folfiri-bevacizumab; ECOG PS 0-1. Primary endpoint is the disease control rate (DCR:ORR plus stable disease > 6 months); secondary endpoints: ORR, PFS, duration of response, OS and toxicity. ORR and DCR were reported with their confidence interval at 95%. Kaplan-Meier method was used for PFS and OS evaluation. RESULTS: 54 patients were enrolled to receive Folfiri-cetuximab after PD to Folfiri-bevacizumab treatment. Median age was 65 (43-80), M/F 31/23, ECOG PS 0/1 was 36/ 18, WT Kras 33(61%). The DCR was 64.8% (CI 95% 52.1-77.5). Among the group of patients with stable or progressive disease at first line treatment, 13.3% of them obtained a response at second line. For second line treatment median duration of response was 6 months and clinical benefit 7 months. The ORR was 22.2% (CI 95% 11.1-33.3). The median progression-free survival was 7 months (CI 95% 6-8). The median overall survival for second line treatment was 14 months (CI 95% 11-17). No grade 4 toxicity was observed. Data suggest that this sequential combination therapy is active and well tolerated. At disease progression to first line chemotherapy treatment the maintenance of the same chemotherapy regimen and the change of the monoclonal antibody showed efficacy in response and survival in patients with mCRC.

ABSTRACT

The addition of bevacizumab to standard chemotherapy has improved progression-free survival (PFS) and overall survival (OS) in patients with metastatic colorectal cancer (mCRC) in both first- and second line treatment, but the role of maintenance bevacizumab remains controversial. The association of various clinical factor and survival was examined in this retrospective cohort analysis. The clinical data from 220 previously untreated patients with mCRC, not progressive at the end of standard chemotherapy plus bevacizumab, were collected and analyzed. Patients were classified into two subgroups: those given with maintenance bevacizumab: "maintenance bevacizumab cohort (n = 118; MB)", and those discontinuing bevacizumab as a result of physician's or patient's decision: "no maintenance bevacizumab cohort (n = 102; noMB)". The baseline factors were well balanced between the study subgroups. Median PFS and OS for the general population was 10 months (range 7-15) and 22.5 months (range 18-26), respectively. Median PFS was 13 and 8 months in the BM and noBM cohorts, respectively (p < 0.0001). In the multivariate analysis, maintenance therapy resulted independently associated with improved PFS (HR 1.73; p < 0.001), but only objective response (OR) after first-line chemotherapy was associated with improved OS. Maintenance chemotherapy cannot be considered a standard of care after induction chemotherapy for mCRC, because the optimal balance between efficacy and safety of maintenance therapy remains a significant challenge. The results of our retrospective study suggest that maintenance therapy with bevacizumab is a safe and valuable option, particularly in those patients achieving an objective response after first-line chemotherapy.

ABSTRACT

BACKGROUND: Anti-epidermal growth factor receptor (EGFR) target therapies like erlotinib for metastatic lung cancer and cetuximab or panitumumab for metastatic colorectal cancer (mCRC) cause skin reaction that seems to be related to treatment efficacy. Skin toxicity evaluation protocol with panitumumab study has shown that preemptive treatment reduces the incidence of ≥Grade 2 (G2) skin toxicity in mCRC treated with panitumumab. Aim of this study is to evaluate if preemptive skin toxicity treatment with different drugs has good efficacy in patients receiving anti-EGFR therapies, such as cetuximab, panitumumab, and erlotinib, for mCRC and metastatic lung cancer. METHODS: Treatment included skin moisturizers with sunscreen and lymecycline 300 mg/daily. Primary objective is to reduce the incidence of ≥G2 skin toxicity during the first 3 months of therapy. Toxicities are reported with confidence interval at 95%. Quality of life was assessed with Dermatology Life Quality Index every 2 weeks and evaluated with repeated measure ANOVA. RESULTS: Fifty-one patients with mCRC (60.8%) and metastatic lung cancer (39.2%) were enrolled. Anticancer drugs were erlotinib/cetuximab/panitumumab 20:30:1. At 3-month evaluation, 27.4% patients had =G2 skin toxicity. Skin toxicity was not related with age (p = 0.67), sex (p = 0.65), previous chemotherapy regimens (p = 0.41), and current anti-EGFR treatment (p = 0.22). No gastrointestinal or hematological toxicities related to lymecycline were observed. Only six patients required further drugs. Quality of life analysis did not show a significant difference from the beginning and the end of treatment. CONCLUSIONS: Data show efficacy of preemptive treatment with a well-tolerated profile. A reduction of severe skin toxicities is shown with an increase of grade 1 toxicities, not leading to anti-EGFR dose reduction and with better quality of life for patients.

ABSTRACT

BACKGROUND: The Edmonton Symptom Assessment Scale (ESAS) is a validated tool for physical symptom assessment in palliative care practice which evaluates symptoms through a numeric scale from 0 to 10. The use of symptom improvement as a prognostic factor is controversial. To this purpose, a pilot study in advanced cancer patients now undergoing only palliative care was conducted. METHODS: Patients were considered eligible if no longer able to receive any anticancer treatment; they were scheduled to undergo ESAS assessment at the hospitalization and hospital discharge time points. Symptoms' scores were divided into three severity classes: mild, moderate and severe. Differences across symptoms' classes between hospitalization and hospital discharge time points were analysed with the paired-data McNemar test, according to tumour types. RESULTS: ESAS assessment was administered to 68 patients with gastrointestinal (39 patients) and non-small cell lung cancer (29 patients); median age was 69 years; Karnofsky Performance Status was 50 in 27 (39.7%) patients and >50 in 41 (60.3%) patients. Palliative Prognostic Score was A for 26 (38.2%) patients, B for 37 (54.4%) patients and C for 5 (7.4%) patients. A statistically significant reduction of severe severity class rates was observed. Symptom improvement correlates with survival improvement: Palliative Prognostic Score (hazard ratio (HR) 2.95, 95% CI 1.35-6.41, p = 0.006) and anorexia (HR 3.21, 95% 1.33-7.72, p = 0.009) appear to be prognostic factors for survival at the multivariate analysis for gastrointestinal cancer patients; asthenia is the only significant variable (HR 5.11, 95% CI 1.86-14.03, p = 0.002) for non-small cell lung cancer patients. CONCLUSIONS: Symptom improvement according to ESAS after palliative care treatment represents an important prognostic for survival in patients no longer suitable to receive any anticancer active therapies.

ABSTRACT

In a previous analysis performed on a cohort of 37 HER-2 positive metastatic breast cancer (MBC) patients treated with trastuzumab beyond progression, we found that a second trastuzumab-based therapy is associated with a considerable response rate and preserved time to progression as compared with a first trastuzumab-based therapy. In the present study, we extended the analysis to a total of 69 patients treated in four different italian Institutions, also trying to identify clinical predictors of sensitivity to a second trastuzumab-based therapy beyond progression. Efficacy results on the overall population confirmed that a second trastuzumab-based therapy beyond progression is an active regimen (27.5% of responses and 6.5 months of time to progression, respectively). Median time to progression to the first trastuzumab therapy (TTP1) identified two groups of patients with different sensitivity to trastuzumab beyond progression (group A, TTP1 >or= 8 months and group B, TTP1 < 8 months) in terms of time to second progression and post-progression survival (group A versus group B showed respectively a time to second progression of 7.6 versus 4.7 months, p = 0.05, and a post-progression survival of 31.7 months versus 21.8 months, p = 0.04). In the multivariate analysis, only TTP1 was a predictor of time to second progression and post-progression survival. Despite the recent approval of lapatinib plus capecitabine for trastuzumab-progressing patients, it is still reasonable to offer trastuzumab beyond progression to HER-2 positive MBC patients, because these data confirm the potential utility of such a conduct. In the clinic, time to first tumor progression may represent a useful tool to identify patients who are more likely to benefit from trastuzumab beyond progression.
