Durvalumab Plus Gemcitabine and Cisplatin Versus Gemcitabine and Cisplatin in Biliary Tract Cancer: a Real-World Retrospective, Multicenter Study.

BACKGROUND: The TOPAZ-1 phase III trial reported a survival benefit with the anti-programmed cell death ligand 1 (anti-PD-L1) durvalumab in combination with gemcitabine and cisplatin in patients with advanced biliary tract cancer (BTC). OBJECTIVE: The present study investigated for the first time the impact on survival of adding durvalumab to cisplatin/gemcitabine compared with cisplatin/gemcitabine in a real-world setting. PATIENTS AND METHODS: The analyzed population included patients with unresectable, locally advanced, or metastatic BTC treated with durvalumab in combination with cisplatin/gemcitabine or with cisplatin/gemcitabine alone. The impact of adding durvalumab to chemotherapy in terms of overall survival (OS) and progression free survival (PFS) was investigated with univariate and multivariate analysis. RESULTS: Overall, 563 patients were included in the analysis: 213 received cisplatin/gemcitabine alone, 350 received cisplatin/gemcitabine plus durvalumab. At the univariate analysis, the addition of durvalumab was found to have an impact on survival, with a median OS of 14.8 months versus 11.2 months [hazard ratio (HR) 0.63, 95% confidence interval (CI) 0.50-0.80, p = 0.0002] in patients who received cisplatin/gemcitabine plus durvalumab compared to those who received cisplatin/gemcitabine alone. At the univariate analysis for PFS, the addition of durvalumab to cisplatin/gemcitabine demonstrated a survival impact, with a median PFS of 8.3 months and 6.0 months (HR 0.57, 95% CI 0.47-0.70, p < 0.0001) in patients who received cisplatin/gemcitabine plus durvalumab and cisplatin/gemcitabine alone, respectively. The multivariate analysis confirmed that adding durvalumab to cisplatin/gemcitabine is an independent prognostic factor for OS and PFS, with patients > 70 years old and those affected by locally advanced disease experiencing the highest survival benefit. Finally, an exploratory analysis of prognostic factors was performed in the cohort of patients who received durvalumab: neutrophil-lymphocyte ratio (NLR) and disease stage were to be independent prognostic factors in terms of OS. The interaction test highlighted NLR ≤ 3, Eastern Cooperative Oncology Group Performance Status (ECOG PS) = 0, and locally advanced disease as positive predictive factors for OS on cisplatin/gemcitabine plus durvalumab. CONCLUSION: In line with the results of the TOPAZ-1 trial, adding durvalumab to cisplatin/gemcitabine has been confirmed to confer a survival benefit in terms of OS and PFS in a real-world setting of patients with advanced BTC.

Streamlining the diagnostic pathway for Lynch syndrome in colorectal cancer patients: a 10-year experience in a single Italian Cancer Center.

BACKGROUND: Universal screening of colorectal cancer (CRC) patients for Lynch syndrome (LS) through MisMatch Repair (MMR) testing is recommended. BRAF V600E mutation and/or MLH1 promoter methylation (Reflex Testing, RefT)generally rule out LS in MLH1-deficient (dMLH1) patients. We estimated the impact of RefTon genetic counseling (GC) and on the diagnostic yield of genetic testing (GT). METHODS: Overall, 3199 CRC patients were referred to our center between 2011 and 2021. Patients referred until January 2019 (n=2536) underwent universal MMR testing and were termed 'Cohort A'; among patients after February 2019 (n=663), 'Cohort B', RefT was also performed in dMLH1 patients. RESULTS: Overall, 401/3199 patients (12.5%) were MMR-deficient (dMMR); 312 (77.8%) in cohort A and 89 (22.2%) inB; 346/401 were dMLH1 (86.3%), 262/312 (83.9%) in cohort A and 84/89 (94.3%) in B. In Cohort A, 91/312 (29.1%) dMMR patients were referred to GC, 69/91 (75.8%) were in the dMLH1 group; 57/69 (82.6%) dMLH1 patients underwent GT and 1/57 (1.7%) had LS. In Cohort B, 3/84 dMLH1 patients did not undergo BRAF testing. Three BRAF wt and not hypermethylated of the remaining 81 dMLH1 patients were referred to GC and GT, and one had LS. This diagnostic pathway reduced GC referrals by 96% (78/81) in Cohort B and increased the diagnostic yield of GT by about 20 times. CONCLUSION: Our findings support RefT in dMLH1 CRC patients within the LS diagnostic pathway, as it reduces the number of GC sessions needed and increases the diagnostic yield of GT.

Cross-trial comparisons for the adjuvant treatment of MSI colorectal cancer: dare to dream the future scenarios.

The remarkable outcomes achieved with neoadjuvant checkpoint inhibitors for patients diagnosed with MSI colorectal cancer hold the potential to revolutionize the treatment landscape in this context. Specifically, the combination of nivolumab plus ipilimumab in colon cancer and dostarlimab in rectal cancer has led to an unprecedented rate of complete pathological and clinical responses. Notably, these responses have been further substantiated by the absence of relapses, with a 0% relapse rate observed during the first year of follow-up. The significance of these achievements becomes even more apparent when compared to the relatively high relapse rates, ranging from 11% to 28%, observed in MSI colorectal cancer cases treated neoadjuvantly with chemo(radio)therapy. However, it is crucial to exercise caution when interpreting such exceptional responses in oncology, especially within a short follow-up period. The future implications of these findings will depend on how the data mature over time. In this manuscript, we attempt to explore the potential scenarios that may unfold in the near future.

Synchronous and metachronous primary colorectal cancers with concordant and discordant mismatch repair status.

Multiple primary colorectal carcinomas (CRCs) synchronous, when detected approximately at the same time, or metachronous, when a significant amount of time has elapsed between diagnoses can show both mismatch repair (MMR) status concordance and discordance between primary tumors. The aim was to evaluate the MMR status of a monoinstitutional, retrospective cohort of synchronous and metachronous CRCs, with a focus on the frequency of cases with discordant MMR status, and explore the MMR status of metastatic nodal deposits. All synchronous and metachronous CRCs diagnosed in our institution between 2011 and 2023 were collected. Clinicopathologic characteristics were evaluated, including MMR status of all CRCs, BRAF mutation, and MLH1 promoter methylation analyses. MMR status discordant cases were further analyzed, and MMR testing was performed on nodal metastases. Of 3671 patients, 107 (2.9%) had multiple CRCs (94 synchronous and 13 metachronous; total number of CRCs 220). Sixty CRCs were MMR deficient (dMMR) (27.3%), and most were right-sided and high-grade and showed special histologic features (P < .00001). Ninety-three patients showed intertumoral MMR concordance: 70 (65.4%) with MMR-proficient (pMMR) CRCs, and 23 (21.5%) were dMMR. Fourteen patients (13.1%) showed intertumoral MMR discordance (at least one dMMR and one pMMR), and in 5 patients, nodal metastases were present: 2 patients harbored metastases only from their pMMR cancer, 2 only from their dMMR cancer, and in 1 patient both pMMR and dMMR metastases were present. In conclusion, all multiple primary CRCs should be analyzed for MMR status as discordant MMR is possible as well as discordant metastatic nodal deposits, and this may be important for patient management.

Durvalumab plus gemcitabine and cisplatin in advanced biliary tract cancer: An early exploratory analysis of real-world data.

BACKGROUND: The TOPAZ-1 phase III trial reported a survival benefit with the anti-programmed death cell ligand 1 (anti-PD-L1) durvalumab in combination with gemcitabine and cisplatin in patients with advanced biliary tract cancer. The present study investigated the efficacy and safety of this new standard treatment in a real-world setting. METHODS: The analysed population included patients with unresectable, locally advanced or metastatic adenocarcinoma of the biliary tract treated with durvalumab in combination with gemcitabine and cisplatin at 17 Italian centres. The primary endpoint of the study was progression-free survival (PFS), whereas secondary endpoints included overall survival (OS), overall response rate (ORR) and safety. Unadjusted and adjusted hazard ratios (HRs) by baseline characteristics were calculated using the Cox proportional hazards model. RESULTS: From February 2022 to November 2022, 145 patients were enrolled. After a median follow-up of 8.5 months (95% CI: 7.9-13.6), the median PFS was 8.9 months (95% CI: 7.4-11.7). Median OS was 12.9 months (95% CI: 10.9-12.9). The investigator-assessed confirmed ORR was 34.5%, and the disease control rate was 87.6%. Any grade adverse events (AEs) occurred in 137 patients (94.5%). Grades 3-4 AEs occurred in 51 patients (35.2%). The rate of immune-mediated AEs (imAEs) was 22.7%. Grades 3-4 imAEs occurred in 2.1% of the patients. In univariate analysis, non-viral aetiology, ECOG PS >0 and NLR ≥3 correlated with shorter PFS. CONCLUSION: The results reported in this first real-world analysis mostly confirmed the results achieved in the TOPAZ-1 trial in terms of PFS, ORR and safety.

Prognostic Value of Body Mass Index in Stage II/III Colon Cancer: Posthoc Analysis From the TOSCA Trial.

BACKGROUND: High body mass index (BMI) plays a key role in the development of colon cancer (CC). Our post-hoc analysis from the TOSCA trial analyzed the association between BMI and survival outcomes in terms of relapse-free survival (RFS) and overall survival (OS) in stage II/III CC patients. PATIENTS AND METHODS: Patients enrolled in the TOSCA trial between 2007-2013 with BMI data entered the study. The prognostic impact of BMI on survival outcomes was investigated through uni- and multivariable Cox regression analyses. RESULTS: Overall, 1455 patients with stage II/III CC patients were included. The median follow-up was of 61.5 months; 16.1% of patients relapsed, 11.2% died and 19.5% patients relapsed or died. No impact of BMI on RFS was detected at univariate or multivariable analyses. By univariate analysis for OS, a significantly impact of a BMI > 30 kg/m2 was reported (HR [>30 vs <25] 1.57, 95% CI 1.00-2.47, p = 0.049; HR [>30 vs <30] 1.55, 95% CI 1.01-2.37, p = 0.045). Multivariable analyses did not confirm this data. In the subgroup of stage III patients, a negative survival impact of BMI was found in univariate and multivariable models both for RFS and for OS. CONCLUSIONS: In our study, obesity with BMI > 30 kg/m2 was an independent prognostic factor for RFS and OS in CC patients treated with adjuvant chemotherapy, regardless of its duration (3 or 6 months). However, the prognostic impact of adiposity and body composition measurement should be considered to better classify patients with high visceral fat and refine their risk assessment.

Reliability of patient-reported toxicities during adjuvant chemotherapy.

BACKGROUND: Patient-reported outcomes (PROs) are validated tools to assess the impact of efficacy and toxicities of cancer treatments on patients' health status. Because of the demonstrated little reliability of humans in reporting memories of painful experiences, this work explores the reliability of cancer patients in reporting chemotherapy-related toxicities. AIM: This study aims to evaluate the concordance between toxicities experienced by the patients during chemotherapy and toxicities reported to the doctor at the end of the cycles. METHODS: Questionnaires concerning chemotherapy-related toxicities were administered on days 2, 5, 8, 11, 14, and 17 of each chemo cycle and at the end of the same cycle to patients undergoing adjuvant chemotherapy. The co-primary end-points were Lins's concordance correlation coefficient (CCC) and mean difference between real-time and retrospective toxicity assessments. RESULTS: In total, 7182 toxicity assessments were collected from 1096 questionnaires. Concordance was observed between the retrospective evaluations and the toxicity assessments at early (day 2), peak (maximum toxicity), late (day 14 or 17), and mean real-time evaluations for each chemotherapy cycle (CCC for mean ranging from 0.52 to 0.77). No systematic discrepancy was found between real-time and retrospective evaluations, except for peak, which was systematically underestimated retrospectively. CONCLUSIONS: Toxicities reported by the patients to the doctor at the end of each chemotherapy cycle reflect what they actually experienced without any substantial distortion. This result is very relevant both for the clinical implications in daily patients' management and in the light of the current growing impact on digital monitoring of PROs.

ctDNA to Guide Treatment of Colorectal Cancer: Ready for Standard of Care?

OPINION STATEMENT: Circulating tumor DNA (ctDNA) has already shown clinically relevant results in early-stage colon cancer patient management. Its prognostic value is by far much stronger than that of the available clinico-pathological biomarkers, therefore, has the potential to personalize the treatment after radical surgery through intensifying or de-intensifying the adjuvant therapy. Further developments and improvements should be pursued by (a) optimizing ctDNA assays and (b) validating its clinical utility in the different stages of this disease. Two main avenues of ctDNA testing are being pursued: tumor-informed vs tumor-agnostic assays. Two main clinical trial designs are under study: ctDNA-based strategy and ctDNA-by-treatment interaction. The former needs large sample sizes to address the main questions of the studies; thus, the target delta benefit may be the main challenge in these trial designs. The latter may be challenged by unavoidable contamination bias. To date, several clinical trials are ongoing worldwide. We believe that this large number of trials may provide an excellent common database for the demonstration of surrogacy of ctDNA for the classical 3-year disease-free survival endpoint. This would mark a huge methodological improvement to speed up new drug testing and development in the adjuvant treatment of this disease.

Clinical Significance of Germline Pathogenic Variants among 51 Cancer Predisposition Genes in an Unselected Cohort of Italian Pancreatic Cancer Patients.

Multigene germline panel testing is recommended for Pancreatic Cancer (PC) patients; however, for non-BRCA1/2 genes, the clinical utility is unclear. A comprehensive multi-gene assessment in unselected Italian PC patients is missing. We evaluated the prevalence and impact of Pathogenic Variants (PV) in 51 PC susceptibility genes in a real-world series of 422 Italian PC patients unselected for Family History (FH), compared the clinical characteristics and conducted survival analyses. 17% of patients had PVs (70/422), mainly in BRCA1/2 (4.5%, all <70 y), CDKN2A (4.5%, all >50 y), ATM (2.1%). PV carriers were younger (64 vs. 67; p = 0.02) and had more frequent personal/FH of PC, melanoma and breast/ovarian cancer (all p < 0.05). The Overall Survival (OS) was longer in patients carrying PVs (HR 0.78; p = 0.090), comprising ATM carriers (HR 0.33; p = 0.054). In the oxaliplatin-treated subset, PV carriers showed better control of the disease, although this was not statistically significant (67% vs. 56%). CDKN2A, BRCA2 and ATM were the most frequently altered genes. ATM PVs were positively associated with OS in 41% of PV carriers, 60% of whom carried CDKN2A,BRCA2 or ATM PVs, had negative FH and would have been missed by traditional referral. Thus, CDKN2A and ATM should be added to BRCA1/2 testing regardless of FH.

Prognostic and predictive molecular biomarkers in advanced colorectal cancer.

The revolution of precision medicine has produced unprecedented seismic shifts in the treatment paradigm of advanced cancers. Among the major killers, colorectal cancer (CRC) is far behind the others. In fact, the great successes obtained in breast, NSCLC, melanoma, and genitourinary tract tumors have been observed only in fewer than 5 % metastatic colorectal cancer (mCRC): those with the mismatch repair deficiency (dMMR), a well-known predictive factor for to the outstanding efficacy of checkpoint inhibitors (CPI). The treatment of the remaining vast majority mCRC patients is still based upon only two molecular determinants: the RAS and BRAF mutational status. New promising biomarkers include HER2, tumor mutational burden (TMB) for its possible implications on CPI efficacy, and the extremely rare NTRK fusions. The Consensus Molecular Subtypes classification (CMS) is a good example of the efforts to combine different molecular features of this disease, although its relevance in clinical practice is still under investigation. In this Review, we focus on all these prognostic and predictive biomarkers, analyzing data from the most important clinical trials of the last years. We also try to rank them according to their prognostic and predictive power.

Association of Delayed Surgery With Oncologic Long-term Outcomes in Patients With Locally Advanced Rectal Cancer Not Responding to Preoperative Chemoradiation.

Importance: Extending the interval between the end of neoadjuvant chemoradiotherapy (CRT) and surgery may enhance tumor response in patients with locally advanced rectal cancer. However, data on the association of delaying surgery with long-term outcome in patients who had a minor or poor response are lacking. Objective: To assess a large series of patients who had minor or no tumor response to CRT and the association of shorter or longer waiting times between CRT and surgery with short- and long-term outcomes. Design, Setting, and Participants: This is a multicenter retrospective cohort study. Data from 1701 consecutive patients with rectal cancer treated in 12 Italian referral centers were analyzed for colorectal surgery between January 2000 and December 2014. Patients with a minor or null tumor response (ypT stage of 2 to 3 or ypN positive) stage greater than 0 to neoadjuvant CRT were selected for the study. The data were analyzed between March and July 2020. Exposures: Patients who had a minor or null tumor response were divided into 2 groups according to the wait time between neoadjuvant therapy end and surgery. Differences in surgical and oncological outcomes between these 2 groups were explored. Main Outcomes and Measures: The primary outcomes were overall and disease-free survival between the 2 groups. Results: Of a total of 1064 patients, 654 (61.5%) were male, and the median (IQR) age was 64 (55-71) years. A total of 579 patients (54.4%) had a shorter wait time (8 weeks or less) 485 patients (45.6%) had a longer wait time (greater than 8 weeks). A longer waiting time before surgery was associated with worse 5- and 10-year overall survival rates (67.6% [95% CI, 63.1%-71.7%] vs 80.3% [95% CI, 76.5%-83.6%] at 5 years; 40.1% [95% CI, 33.5%-46.5%] vs 57.8% [95% CI, 52.1%-63.0%] at 10 years; P < .001). Also, delayed surgery was associated with worse 5- and 10-year disease-free survival (59.6% [95% CI, 54.9%-63.9%] vs 72.0% [95% CI, 67.9%-75.7%] at 5 years; 36.2% [95% CI, 29.9%-42.4%] vs 53.9% [95% CI, 48.5%-59.1%] at 10 years; P < .001). At multivariate analysis, a longer waiting time was associated with an augmented risk of death (hazard ratio, 1.84; 95% CI, 1.50-2.26; P < .001) and death/recurrence (hazard ratio, 1.69; 95% CI, 1.39-2.04; P < .001). Conclusions and Relevance: In this cohort study, a longer interval before surgery after completing neoadjuvant CRT was associated with worse overall and disease-free survival in tumors with a poor pathological response to preoperative CRT. Based on these findings, patients who do not respond well to CRT should be identified early after the end of CRT and undergo surgery without delay.

Oxaliplatin plus fluoropyrimidines as adjuvant therapy for colon cancer in older patients: A subgroup analysis from the TOSCA trial.

BACKGROUND: Previous studies on oxaliplatin and fluoropyrimidines as adjuvant therapy in older patients with stage III colon cancer (CC) produced conflicting results. PATIENTS AND METHODS: We assessed the impact of age on time to tumour recurrence (TTR), disease-free survival (DFS), cancer-specific survival (CSS), and overall survival (OS) in 2360 patients with stage III CC (1667 aged <70 years and 693 ≥ 70 years) randomised to receive 3 or 6 months of FOLFOX or CAPOX within the frame of the phase III, TOSCA study. RESULTS: Older patients compared with younger ones presented more frequently an Eastern Cooperative Oncology Group performance status equal to 1 (10.5% vs 3.3%, p < 0.001), a greater number of right-sided tumours (40.9% vs 26.6%, p < 0.001), and were at higher clinical risk (37.2% vs 33.2%, p = 0.062). The treatments were almost identical in the two cohorts (p = 0.965). We found a greater proportion of dose reductions (46.7% vs 41.4%, p = 0.018), treatment interruptions (26.1% vs 19.3%, p < 0.001) and a higher proportion of recurrences (24.2% vs 20.3%, p = 0.033) in the older patients. The multivariable analysis of the TTR did not indicate a statistically significant effect of age (hazard ratio [HR]: 1.19; 95% confidence interval [CI]: 0.98-1.44; p = 0.082). The HR comparing older with younger patients was 1.34 (95% CI: 1.12-1.59; p = 0.001) for DFS, 1.58 (95% CI: 1.26-1.99; p < 0.001) for OS, and 1.28 (95% CI: 0.96-1.70; p = 0.089) for CSS. CONCLUSIONS: Worse prognostic factors and reduced treatment compliance have a negative impact on the efficacy of oxaliplatin-based adjuvant therapy in older patients.

Non-Operative Management Versus Total Mesorectal Excision for Locally Advanced Rectal Cancer with Clinical Complete Response After Neoadjuvant Chemoradiotherapy: a GRADE Approach by the Rectal Cancer Guidelines Writing Group of the Italian Association of Medical Oncology (AIOM).

BACKGROUND: The standard approach for locally advanced rectal cancer (LARC) is neoadjuvant chemoradiotherapy (nCRT) followed by total mesorectal excision (TME). After nCRT 20% of patients achieve a clinical complete response (pCR) and could be treated with a non-operative management (NOM). METHODS: The panel of the Italian Association of Medical Oncology (AIOM) Guidelines on rectal cancer applied the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach addressing the following question: Should NOM vs. TME be used for patients with rectal cancer with clinical complete response after nCRT? Five outcomes were identified: disease-free survival (DFS), mortality, local recurrence, colostomy rate, and functional outcomes. RESULTS: Nine studies were included in the analysis. A higher risk of disease recurrence was observed in the NOM group compared to the TME group (RR = 1.69, 95% CI 1.08, 2.64) on the other hand, we observed a slightly positive but not significant effect on mortality of NOM (RR = 0.82, 95% CI 0.46, 1.45). Patients in the NOM group were more likely to experience local recurrence (RR = 5.37, 95% CI 2.56, 11.27) and patients in the TME group were more likely to have a permanent colostomy (RR = 0.15, 95% CI 0.08, 0.29). Only one study evaluated functional outcomes. The overall certainty of evidence was rated as very low. CONCLUSIONS: NOM was found to correlate with a higher risk of local recurrence which did not translate in worse OS and a lower colostomy rate. Due to the paucity of evidences, no recommendations are possible. NOM remains an experimental treatment; thus, patients managed with NOM should be enrolled in clinical trials with a dedicated follow-up schedule.

Primary melanoma of the bladder: Case report and review of the literature.

Skin melanoma represents one of the most common and lethal solid tumor. It usually develops on the skin but it can occur in any tissues with melanine- containing-cells (extracutaneous malignant melanoma). Only 4-5% of malignant melanomas originate in extracutaneous tissues, and they have an extremely lethal behavior (1). These non-skin malignant melanomas are rare but extremely aggressive. Primary melanoma of the genitourinary tract accounts for less than 0.2% of all melanomas. To date only 28 cases of primary bladder melanoma (PMM) are described. We report a rare case of PMM of the bladder in a 72 years old man treated with radical cystectomy and immunotherapy with Nivolumab.

The outcome to axitinib or everolimus after sunitinib in metastatic renal cell carcinoma.

We aimed to investigate the different outcomes in patients with metastatic renal cell carcinoma treated with second-line axitinib or everolimus after sunitinib. Patients treated in 16 oncological centres in Italy were included, and those receiving axitinib or everolimus from January 2013 onwards were analysed for outcomes. Descriptive statistical tests were used to highlight differences between groups. The Kaplan-Meier method was used to estimate overall survival (OS) and progression-free survival (PFS). Data on 634 patients with metastatic renal cell carcinoma treated with first-line sunitinib have been obtained. A total of 182 patients received a second-line therapy with everolimus (79 patients, 43%) or axitinib (103 patients, 57%), respectively. The median PFS was 4.6 [95% confidence (CI): 2.6-6.5] months for patients treated with everolimus and 5.5 (95% CI: 4.3-6.7) months for patients treated with axitinib (P=0.7). The median OS was 13.9 (95% CI: 10.4-17.4) months for patients treated with everolimus and 12.0 (95% CI: 7.9-16.2) months for patients treated with axitinib (P=0.3). No differences were found based on length of first-line treatment. Major limitations are the retrospective nature of the study and the lack of a prospective evaluation of the progression. This study reports no significantly differences between everolimus and axitinib in terms of both PFS and OS. Furthermore, the length of first-line treatment cannot be used as such a predictive factor and cannot suggest the use of a molecule compared with another.

Aflibercept Plus FOLFIRI in the Real-life Setting: Safety and Quality of Life Data From the Italian Patient Cohort of the Aflibercept Safety and Quality-of-Life Program Study.

BACKGROUND: Aflibercept combined with FOLFIRI (folinic acid, 5-fluorouracil, irinotecan) as second-line treatment of metastatic colorectal cancer (mCRC) significantly improved survival compared with FOLFIRI alone in the pivotal VELOUR (aflibercept vs. placebo in combination with irinotecan and 5-fluorouracil in the treatment of patients with metastatic colorectal cancer after failure of an oxaliplatin-based regimen) trial. No quality-of-life assessment was performed in VELOUR; therefore, the ASQoP (Aflibercept Safety and Quality-of-Life Program) trial was designed to capture the safety and health-related quality of life (HRQL). PATIENTS AND METHODS: ASQoP was an international, open-label, single-arm trial evaluating the safety and HRQL of aflibercept combined with FOLFIRI administered in a real-life setting to 781 patients with mCRC, pretreated with an oxaliplatin-based regimen with or without bevacizumab. The Italian subset of ASQoP enrolled 200 patients from 28 institutions. The primary endpoint was safety; HRQL was a secondary endpoint, assessed by validated questionnaires (European quality of life 5-dimension instrument 3-level; European Organization for Research and Treatment for Cancer Quality of Life Questionnaire Core 30, version 3; and EORTC-CR29) at baseline, during treatment, and at the end of treatment. RESULTS: The median age of the Italian ASQoP population was 63 years; the median number of aflibercept and FOLFIRI cycles was 7. Treatment-emergent adverse events were reported in 97.5% of patients. Hypertension (28.5%), neutropenia (27.5%; from laboratory data), asthenic conditions (20.0%), diarrhea (17.0%), and stomatitis (13.0%) were the most frequent (incidence, ≥ 5%) grade 3/4 toxicities. One toxic death occurred during the study period due to sepsis, without neutropenic complications. No significant worsening of HRQL was shown during treatment. CONCLUSION: Aflibercept combined with FOLFIRI was well tolerated when administered as second-line treatment for patients with mCRC in a real-life setting. It did not affect HRQL and showed similar rates of treatment-emergent adverse events as those observed in the VELOUR trial. No new safety signals were identified.
