J Neuroendocrinol 2023; 35:e13227. [PMID: 36599808 PMCID: PMC10078167 DOI: 10.1111/jne.13227] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 11/29/2022] [Accepted: 12/14/2022] [Indexed: 12/28/2022]
Abstract
Neuroendocrine tumors (NETs) are highly vascularized neoplasms. While FOLFOX chemotherapy has shown efficacy in patients with advanced NETs, its combination with antiangiogenics has been scarcely described. Here, we report the efficacy and tolerance of FOLFOX-bevacizumab in this setting. We retrospectively studied all consecutive patients with metastatic NET treated by FOLFOX-bevacizumab in two expert centers from 2013 to 2020. We assessed time to treatment failure (TTF), objective response rate (ORR) and toxicity. We explored factors associated with TTF and ORR using multivariate analyses. We included 57 patients (35.1% female, median age 61.7 years), with pancreatic (66.7%), small-intestine (14%) or lung (7%) NETs. Most patients (57.9%) had extra-hepatic metastases and G3 NETs accounted for 40.3% of cases. Patients received a median of 17 cycles of treatment, including a median of seven cycles of bevacizumab and/or 5-fluorouracile maintenance. Median TTF was 15.5 months (95% CI: 9.8-21.2) and was shorter in patients age > 60 years (HR 2.56, 95% CI: 1.16-5.64), p = .020) and >1 previous systemic treatment line (HR 4.15, 95% CI: 1.96-8.78), p < .001). The ORR was 42.9% and was higher in cases of performance status at 0 (OR 5.25, 95% CI: 1.13-24.35), p = .034) and G3 NET (OR 5.39, 95% CI: 1.23-23.52), p = .025). The FOLFOX-bevacizumab combination has promising efficacy in patients with progressive metastatic NETs and notably for G3 NETs, for which optimal treatment as yet remains ill-defined. Hence, it could be a relevant alternative to alkylating-based chemotherapy in this setting and should be further explored prospectively.

Abstract
Colorectal cancer (CRC) is one of the most common malignancies worldwide. Patients with CRC may need chemotherapy (CTx) in a neoadjuvant, adjuvant or palliative setting through the course of the disease. Unfortunately, its effect is limited by chemoresistance and chemotoxicity. Novel more effective and non‑toxic CTx regimens are needed to further improve CRC treatment outcomes. Thus, the present study was designed to test the hypothesis that non‑toxic sulforaphane (SF) is effective against CRC and has additive effects in combination with conventional 5‑fluorouracil, oxaliplatin and folinic acid (FOLFOX) CTx in vitro. Highly metastatic human colon cancer cells, CX‑1, and fibroblasts were treated with FOLFOX ± SF. Cell viability was assessed using an MTT assay. The level of apoptosis and the expression of apoptotic proteins were measured by TUNEL assay and quantitative PCR analysis. Aldehyde dehydrogenase isoform 1 (ALDH1) and multidrug resistance protein 2 (MRP2) levels were evaluated. The ability of cells to form spheroids was measured in three‑dimensional cell culture. SF alone and in combination with FOLFOX effectively decreased the viability of the CX‑1 cells, promoted apoptosis within the CX‑1 cells, prevented cellular spheroid formation and decreased ALDH1 activity. However, SF promoted MRP2 expression and protein levels. In conclusion, SF together with conventional FOLFOX has additive anticancer effects against highly metastatic human CRC in vitro.

Treatment outcomes of advanced hepatocellular carcinoma in real-life practice: Chemotherapy versus multikinase inhibitors. Cancer Med 2022; 12:3046-3053. [PMID: 36082831 PMCID: PMC9939209 DOI: 10.1002/cam4.5224] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 07/24/2022] [Accepted: 08/23/2022] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND Multikinase inhibitors (MKIs) represent the main treatment options for advanced hepatocellular carcinoma (aHCC). However, accessibility in developing countries is limited. A chemotherapy, Fluorouracil and Oxaliplatin (FOLFOX), offers a less expensive treatment. Therefore, this study sought to compare the clinical effectiveness of FOLFOX with Sorafenib as a first-line treatment for aHCC in real-life practice. METHODS A retrospective aHCC cohort from four Thai hospitals was investigated for patients who received FOLFOX or Sorafenib between 2013-2019. Multiple imputation by chained equations addressed missing covariate data in a treatment effect model using Weight-adjusted-censoring inverse-probability-weighted regression adjustment; overall survival (OS) and progression-free survival (PFS) were estimated. RESULTS A total of 504 patients were included, (Sorafenib [n = 382] and FOLFOX [n = 122]). The treatment effect model estimated a median OS for Sorafenib and FOLFOX of 11.38 and 8.22 months, representing a significantly shorter OS (95% confidence interval) of -3.16 (-6.21, -0.11) months for FOLFOX, p = 0.042. A significant shorter median PFS of FOLFOX to Sorafenib of -2.13 (-3.03, -1.24) months, p < 0.001, was reported. CONCLUSION Despite significantly shorter median OS and PFS than Sorafenib, FOLFOX still extended OS by 8.22 months. This evidence may offer clinical utility to physicians considering treatment options for aHCC in low resource settings.

Abstract
BACKGROUND An uninterrupted dose of oxaliplatin-based cytotoxic therapy is an essential component in the standard treatment regimen of metastatic colon cancer (mCC). Data on the impacts of dose intensity reduction on the palliative treatment for patients with mCC remain scarce. Hence, this study aimed to investigate the impact of palliative chemotherapy dose modifications (DM) on the survival of patients with mCC. METHODS Patients with stage IV colon cancer who received first-line palliative FOLFOX regimen chemotherapy between 2014 until 2018 in the Oncology Department of the National Cancer Institute were conveniently sampled retrospectively to analyse the treatment efficacy. The cumulative dose and duration of chemotherapy received by the patients were summarised as relative dose intensity (RDI) and stratified as High RDI (RDI ≥ 70%) or Low RDI (RDI < 70%). Progression-free survival (PFS) and 2-year overall survival (OS) between the two groups were analysed using Kaplan-Meier survival analysis and Cox proportional hazards models. RESULTS Out of the 414 patients identified, 95 patients with mCC were eligible and included in the final analysis. About half of the patients (n = 47) completed the 12-cycle chemotherapy regimen and one patient received the complete (100%) RDI. The overall median RDI was 68.7%. The Low RDI group (n = 49) had a 1.5 times higher mortality risk than the High RDI group [OS, Hazard Ratio (HR) = 1.5, 95% Cl: 1.19-1.82] with a significant median OS difference (9.1 vs. 16.0 months, p < 0.01). Furthermore, patients with lower dose intensity showed double the risk of disease progression (PFS, HR = 2.0, 95% CI: 1.23-3.13) with a significant difference of 4.5 months of median PFS (p < 0.01). Gender and RDI were the independent prognostic factors of both OS and PFS. CONCLUSION Reduction in the dose intensity of palliative chemotherapy may adversely affect both disease progression and overall survival among mCC patients.

Abstract
This study aimed to explore the safety and efficacy of neoadjuvant SCRT and tegafur−uracil/leucovorin plus oxaliplatin (TEGAFOX) for LARC in comparison to those of the modified 5-fluorouracil, leucovorin, and oxaliplatin (mFOLFOX-6) regimen. We retrospectively evaluated 15 and 22 patients with LARC who underwent SCRT, followed by consolidation chemotherapy with TEGAFOX and mFOLFOX-6 before surgery, respectively, between January 2015 and December 2019. The primary endpoint was the tumor response rate. The secondary endpoints were compliance, toxicity, complications, overall survival (OS), and disease-free survival (DFS). The dose reduction rate was lower in the TEGAFOX group (0 vs. 9.1% (n = 2)). No grade III-IV toxicities occurred in the TEGAFOX group. Two and four patients in the TEGAFOX and mFOLFOX-6 groups, respectively, achieved clinical complete responses. The pathologic complete response rate was lower in the TEGAFOX group (7.7% vs. 17.6%). Overall, 11 (73.3%) and 17 (81.0%) patients had a neoadjuvant rectal (NAR) score of <16 in the TEGAFOX and mFOLFOX-6 groups, respectively. All patients in this study received sphincter-preservation surgery. One patient in each group developed Clavien−Dindo grade III complications. There were no significant between-group differences in the 3-year OS (81.8% vs. 84.8%, p = 0.884) and 3-year DFS (72% vs. 71.6%, p = 0.824) rates. TEGAFOX, as consolidation chemotherapy after SCRT, achieves good tumor downstaging and patient compliance in LARC. The toxicity, complications, and surgical outcomes are similar to those of mFOLFOX-6. Thus, TEGAFOX can be considered a chemotherapy option for rectal cancer treatment.

Abstract
Salvage chemotherapy for patients with unresectable pancreatic cancer (UR-PC) who have been treated with gemcitabine and nab-paclitaxel (GnP), and 5-fluorouracil (5-FU)/l-leucovorin (LV) plus nanoliposomal irinotecan (nal-IRI), has not been fully established. We retrospectively reviewed data from 17 patients with UR-PC who initiated 5-FU/l-LV plus oxaliplatin (FOLFOX) as salvage chemotherapy at our hospital between June 2020 and August 2021, after treatment with GnP and 5-FU/LV plus nal-IRI. The primary endpoint was tumor response. The secondary endpoints were progression-free survival (PFS) and adverse events (AEs). The response and disease control rates were 5.9% (1/17) and 17.6% (3/17), respectively. The median PFS was 1.8 months (range: 0.4-5.2 months). Eight patients (47.1%) experienced grade 3 nonhematologic AEs, while none experienced grade 3 hematologic AEs. Two patients with controlled disease had homologous recombination deficiency (HRD)-associated gene mutations in cancer panel testing. The FOLFOX regimen benefit for UR-PC patients treated with GnP and 5-FU/LV plus nal-IRI may be limited to patients with HRD-associated gene mutations.

Abstract
BACKGROUND FOLFOX plus bevacizumab is a standard of care (SOC) for first-line treatment of microsatellite-stable metastatic colorectal cancer (MSS mCRC). This study randomized patients to SOC or SOC plus avelumab (anti-PD-L1) plus CEA-targeted vaccine. METHODS Patients with untreated MSS mCRC enrolled to a lead-in arm assessing safety of SOC + immuno-oncology agents (IO). Next, patients were randomized to SOC or SOC + IO. The primary endpoint was progression-free survival (PFS). Multiple immune parameters were analyzed. RESULTS Six patients enrolled to safety lead-in, 10 randomized to SOC, and 10 to SOC + IO. There was no difference in median PFS comparing SOC versus SOC + IO (8.8 months (95% CI: 3.3-17.0 months) versus 10.1 months (95% CI: 3.6-16.1 months), respectively; hazard ratio 1.061 [P = .91; 95% CI: 0.380-2.966]). The objective response rate was 50% in both arms. Of patients analyzed, most (8/11) who received SOC + IO developed multifunctional CD4+/CD8+ T-cell responses to cascade antigens MUC1 and/or brachyury, compared to 1/8 who received SOC alone (P = .020). We detected post-treatment changes in immune parameters that were distinct to the SOC and SOC + IO treatment arms. Accrual closed after an unplanned analysis predicted a low likelihood of meeting the primary endpoint. CONCLUSIONS SOC + IO generated multifunctional MUC1- and brachyury-specific CD4+/CD8+ T cells despite concurrent chemotherapy. Although a tumor-directed immune response is necessary for T-cell-mediated antitumor activity, it was not sufficient to improve PFS. Adding agents that increase the number and function of effector cells may be required for clinical benefit.

Abstract
Regulatory T cells (Tregs) are a subset of CD4+ T lymphocytes known to dampen the host immune response against cancer cells. Within the tumor microenvironment, Tregs are potent facilitators of immune tolerance, and a higher proportion of Tregs compared to cytotoxic T cells predicts a worse outcome in most solid tumors. We studied the association between Treg density, and cancer biology and clinical outcome in colorectal cancer (CRC). We used xCell to estimate intratumoral Tregs in total of 898 CRC patients in the Cancer Genome Atlas (TCGA) and GCE39582 cohorts. High-Treg CRCs enriched immune response-related gene sets; inflammatory response, IFN-γ and IFN-α response, IL2/IL6 signaling, and allograft rejection, and had significantly high infiltration of CD8, CD4, M1 and M2 macrophage, and dendritic cells in both cohorts. While high-Treg CRCs enriched multiple pro-cancer signaling pathways compared to low-Treg CRCs, such as Epithelial Mesenchymal Transition, K-ras, Hypoxia, TGF-β, TNF-α, and angiogenesis, Treg infiltration was surprisingly associated with earlier CRC stage in TCGA. Notably, in two separate cohorts a higher proportion of Tregs predicted an improved response to chemotherapy. In the GSE28702 cohort, metastatic CRCs with more Tregs showed a significantly better response to mFOLFOX6 versus low-Treg CRC metastases (88.9% response vs. 16.7%, P<0.001). In the GSE72970 cohort, high-Treg CRCs were found to have a 68.8% response to FOLFOX/FOLFIRI without bevacizumab, compared to 44% response in the low-Treg CRCs. Additionally, high-Treg CRCs were associated with increased expression of immune checkpoint molecules PD-L1/PD-L2, CTLA4, TIGIT and BTLA, implying susceptibility to immunotherapy. We also found that CRCs with higher proportions of Tregs were associated with lower amounts of three microorganisms in the tumor: Lachnoclostridium, flavivirus, and Ornithobacterium. In conclusion, we show that amount of Treg in the tumor is a predictor of host immune response and chemotherapy response in CRC.

Abstract
BACKGROUND Although second-line treatment for pancreatic cancer has been proven to have survival benefit, it is not clear which is the most preferred regimen. This study compared the efficacy and safety of modified FOLFIRINOX (mFOLFIRINOX) and sequential chemotherapy (FOLFIRI/FOLFOX) as a second-line treatment regimen for unresectable pancreatic cancer. METHOD This was a retrospective single-center analysis of all patients who initiated treatment with mFOLFIRINOX or sequential chemotherapy from December 2014 to May 2019 as a second-line treatment for unresectable pancreatic cancer. The sequential chemotherapy group included all patients who initiated sequential chemotherapy. For efficacy analysis, the primary endpoint was overall survival (OS) of all patients, excluding those with locally advanced pancreatic cancer. For safety analysis, we assessed the incidence of grade ≥3 adverse events in all patients. RESULTS Seventy-four patients (mFOLFIRINOX group, n = 44; sequential chemotherapy group, n = 30) were included. OS tended to be slightly prolonged in the mFOLFIRINOX group than in the sequential chemotherapy group (median 10.6 [95% confidence interval {CI} 5.9-13.8] vs. 8.5 [95% CI 5.0-12.2] months; hazard ratio 1.40 [95% CI 0.71-2.71]). The objective response rate and disease control rate were 8.1% and 64.9%, respectively, in the mFOLFIRINOX group and 3.8% and 42.3%, respectively, in the sequential chemotherapy group. In safety analysis, the grade ≥3 rates of neutropenia, febrile neutropenia, and anorexia were 40.9%, 6.8%, and 18.2%, respectively, in the mFOLFIRINOX group and 3.3%, 0%, and 3.3%, respectively, in the sequential chemotherapy group. CONCLUSIONS Whereas efficacy tended to be slightly better in the mFOLFIRINOX group than in the sequential chemotherapy group, given the higher incidence of grade ≥3 adverse events with mFOLFIRINOX than with sequential chemotherapy, sequential chemotherapy is a regimen with better risk-benefit balance than mFOLFIRINOX, and can be considered a second-line treatment option for patients with unresectable pancreatic cancer.

Abstract
PURPOSE In this follow-up of the R-NAC-01 study, we assessed the long-term oncological benefit of four courses of modified leucovorin, 5-fluorouracil (FU), and oxaliplatin (mFOLFOX6) chemotherapy before rectal surgery. METHODS In this prospective, multicenter study (UMIN 000012559) involving 11 hospitals in Japan, patients with lower rectal cancer underwent four cycles of mFOLFOX6 chemotherapy and subsequent surgery within four to six weeks. The 3-year recurrence-free survival and local recurrence rates were then reported. RESULTS Of 41 patients (36 males, 5 females; mean age: 60.8 years old) who received 4 courses of chemotherapy, 40 underwent total mesorectal excision, and 1 underwent total pelvic exenteration. R0 resection was achieved in 40 patients, but none showed a pathological complete response. Twenty-nine patients received adjuvant chemotherapy for an average of 4 months. The 3 year recurrence-free survival and local recurrence rates in patients undergoing curable resection were 72.8% and 8.5%, respectively. cStage III patients with adjuvant chemotherapy had a significantly higher 3 year recurrence-free survival than those without adjuvant chemotherapy (76.6 vs. 40.0%, log-rank p = 0.03). CONCLUSION Four courses of mFOLFOX6 chemotherapy before surgery may be a promising treatment strategy for locally advanced rectal cancer. Adjuvant chemotherapy might be needed for cStage III patients, even after four courses of neoadjuvant mFOLFOX6.

Abstract
INTRODUCTION Oxaliplatin-based regimens have shown promising antitumor activity in digestive neuroendocrine tumors (NETs); however, the available data are limited. Our aim was to assess the efficacy of FOLFOX (association of 5-fluorouracil with oxaliplatin) in a large series of patients with advanced digestive NETs. METHODS All patients with advanced digestive well-differentiated NETs treated with at least 3 cycles of FOLFOX between January 2004 and December 2018 in 12 centers from the French Group of Endocrine Tumors were included. Tumor response rate according to Response Evaluation Criteria in Solid Tumors version 1.1 criteria, progression free survival (PFS), and overall survival, as well as prognostic factors, were analyzed retrospectively. RESULTS One hundred fifty-five patients were included. Primary tumor locations were pancreas (n = 89), small intestine (n = 40), unknown with no evidence for lung primary (n = 13), stomach (n = 7), and rectum (n = 6). Median Ki-67 was 10%, and 65% of the tumors were grade 2. The partial response rate was 30% for pancreatic NETs, 12.5% for small intestine NETs, 38.5% for unknown primary NETs, 14% for gastric NETs, and 17% for rectal NETs. Significant prognostic factors for poor PFS after FOLFOX were progressive disease at the beginning of treatment (hazard ratio [HR] = 1.83, p = 0.007), hepatic involvement superior to 50% (HR = 2.67, p = 0.0001), and rectal primary tumor location (HR = 2.6, p = 0.0036). Among pancreatic NETs, insulinomas had a better median PFS (22 months) than other pancreatic NETs (9 months, p = 0.026) and showed a high rate (8/9) of serum glucose normalization. CONCLUSIONS FOLFOX shows a promising antitumor activity in advanced digestive NETs. Rapid symptomatic response is observed in metastatic insulinomas.

Abstract
Oxaliplatin-based chemotherapy with a regimen such as FOLFOX with or without targeted therapy is a standard of care option for advanced colorectal cancer; however, long-term exposure to oxaliplatin is associated with cumulative toxicity. Growing evidence suggests maintenance therapy with a less intensive regimen after platinum-based induction therapy can provide continuing benefit with reduced toxicity. We describe the rationale and design of the Phase III LYNK-003 trial, which will evaluate the efficacy and safety of olaparib with or without bevacizumab compared with 5-fluoruracil plus bevacizumab in patients with unresectable or metastatic colorectal cancer that has not progressed on an induction course of FOLFOX plus bevacizumab. The primary end point is progression-free survival by independent central review; secondary end points include overall survival, objective response, duration of response and safety. Clinical trial registration: NCT04456699.

Abstract
Background Few data regarding post-induction management following first-line anti-epidermal growth factor receptor (EGFR)-based doublet regimens in patients with left-sided RAS/BRAF wild-type metastatic colorectal cancer (mCRC) are available. Methods This multicenter, retrospective study aimed at evaluating clinicians’ attitude, and the safety and effectiveness of post-induction strategies in consecutive patients affected by left-sided RAS/BRAF wild-type mCRC treated with doublet chemotherapy plus anti-EGFR as first-line regimen, who did not experience disease progression within 6 months from induction initiation, at 21 Italian and 1 Spanish Institutions. The measured clinical outcomes were: progression-free survival (PFS), overall survival (OS), adverse events, and objective response rate (ORR). Results At the data cutoff, among 686 consecutive patients with left-sided RAS/BRAF wild-type mCRC treated with doublet plus anti-EGFR as first-line regimen from March 2012 to October 2020, 355 eligible patients have been included in the present analysis. Among these, 118 (33.2%), 66 (18.6%), and 11 (3.1%) received a maintenance with 5-fluorouracil/leucovorin (5FU/LV)+anti-EGFR, anti-EGFR, and 5FU/LV, respectively, while 160 (45.1%) patients continued induction treatment (non-maintenance) until disease progression, unacceptable toxicity, patient decision, or completion of planned treatment. The median period of follow-up for the overall population was 33.7 months (95%CI = 28.9–35.6). The median PFS values of the 5FU/LV+anti-EGFR, anti-EGFR, 5FU/LV, and non-maintenance cohorts were 16.0 (95%CI = 14.3–17.7, 86 events), 13.0 (95%CI = 11.4–14.5, 56 events), 14.0 (95%CI = 8.1–20.0, 8 events), and 10.1 months (95%CI = 9.0–11.2, 136 events), respectively (p < 0.001). The median OS values were 39.6 (95%CI = 31.5–47.7, 43 events), 36.1 (95%CI = 31.6–40.7, 36 events), 39.5 (95%CI = 28.2–50.8, 4 events), and 25.1 months (95%CI = 22.6–27.6, 99 events), respectively (p < 0.001). After adjusting for key covariates, a statistically significant improvement in PFS in favor of 5FU/LV+anti-EGFR (HR = 0.59, 95%CI = 0.44–0.77, p < 0.001) and anti-EGFR (HR = 0.71, 95%CI = 0.51–0.98, p = 0.039) compared to the non-maintenance cohort was found. Compared to the non-maintenance cohort, OS was improved by 5FU/LV+anti-EGFR (HR = 0.55, 95%CI = 0.38–0.81, p = 0.002) and, with marginal significance, by anti-EGFR (HR = 0.67, 95%CI = 0.51–0.98, p = 0.051). No difference was found in ORR. Any grade non-hematological and hematological events were generally higher in the non-maintenance compared to the maintenance cohorts. Conclusion Among the treatment strategies following an anti-EGFR-based doublet first-line induction regimen in patients affected by left-sided RAS/BRAF wild-type mCRC treated in a “real-life” setting, 5FU/LV+anti-EGFR resulted the most adopted, effective, and relatively safe regimen.

Abstract
Background To compare the treatment effectiveness and safety among transarterial infusion chemotherapy (TAI) with FOLFOX regimen, transarterial chemoembolization (TACE), and sorafenib in patients with BCLC stage C hepatocellular carcinoma (HCC). Methods The data of consecutive patients with BCLC stage C HCC treated with TAI, TACE, or sorafenib from January 2015 to December 2018 at three centers were retrospectively analyzed. Propensity-score matched (PSM) analysis was pairwise performed to reduce selection bias. Treatment effectiveness and safety were evaluated and compared using the Kaplan-Meier method, log-rank test, Cox regression models, and χ2 test. Results The median overall survival (OS) in the matched TAI cohort was significantly longer than the sorafenib cohort (19.6 vs. 7.5 months, P=0.009), and the TACE cohort (estimated 27.8 vs. 6.6 months, P<0.001). The difference in median progression-free survival (PFS) between the matched TAI and sorafenib cohorts was not significant (5.8 vs. 2.3 months, P=0.219). The median PFS in the matched TAI cohort was significantly longer than the TACE cohort (6.5 vs. 2.8 months, P<0.001). The objective response rate (ORR) in the matched TAI cohort was significantly higher than the sorafenib cohort (36.4% vs. 0.0%, P<0.001) and the TACE cohort (48.7% vs. 4.7%, P<0.001). The incidences of adverse events (AEs) were similar among these three cohorts. Conclusions TAI with FOLFOX regimen was an effective and safe therapy that improved survival of patients with BCLC stage C HCC.

Abstract
Background Hepatic arterial infusion chemotherapy (HAIC) is one option for treating massive tumors and unresectable hepatocellular carcinoma (HCC). However, there is a lack of remedial treatment after these treatments are ineffective or failed. Summary Some studies have discovered that HAIC has greater survival in patients with advanced HCC. A previous study has shown that HAIC is effective in the treatment of advanced HCC, and the data on randomized clinical trials are limited and unclear. Key Message More clinical trials and research are needed in order to make HAIC a standard and recommended therapy for advanced HCC. Our review focuses on the clinical applications of hepatic artery infusion treatment.

Abstract
FOLFOX (oxaliplatin, fluorouracil and calcium folinate) is the first-line chemotherapy regimen for colon cancer therapy in the clinic. It provides superior efficacy than oxaliplatin alone, but the underlying mechanism remains unclear. In the present study, pharmacomicrobiomics integrated with metabolomics was conducted to uncover the role of the gut microbiome behind this. First, in vivo study demonstrated that FOLFOX exhibited better efficacy than oxaliplatin alone in colon cancer animal models. Second, 16S rDNA gene sequencing analysis showed that the abundance of Akkermansia muciniphila (A. muciniphila) remarkably increased in the FOLFOX treated individuals and positively correlated with the therapeutic effect. Third, further exploration confirmed A. muciniphila colonization significantly enhanced the anti-cancer efficacy of FOLFOX. Last, metabolomics analysis suggested dipeptides containing branched-chain amino acid (BCAA) might be responsible for gut bacteria mediated FOLFOX efficacy. In conclusion, our study revealed the key role of A. muciniphila in mediating FOLFOX efficacy, and manipulating A. muciniphila might serve as a novel strategy for colon cancer therapy.

Abstract
PURPOSE 5-Fluorouracil/leucovorin, oxaliplatin, irinotecan (FOLFOXIRI) plus bevacizumab is more effective than doublets plus bevacizumab as first-line therapy for metastatic colorectal cancer, but is not widely used because of concerns about toxicity and lack of predictive biomarkers. This study was designed to explore the role of circulating tumour cell (CTC) count as a biomarker to select patients for therapy with FOLFOXIRI-bevacizumab. PATIENTS AND METHODS VISNÚ-1 was a multicentre, open-label, randomised, phase III study in patients with previously untreated, unresectable, metastatic colorectal carcinoma and ≥3 CTC/7.5 mL blood. Patients received bevacizumab 5 mg/kg plus FOLFOXIRI (irinotecan 165 mg/m2, oxaliplatin 85 mg/m2, leucovorin 400 mg/m2 and 5-fluorouracil 3200 mg/m2) or FOLFOX (oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, 5-fluorouracil 400 mg/m2 then 2400 mg/m2) by intravenous administration every 2 weeks. The primary outcome was progression-free survival (PFS). RESULTS The intention-to-treat population comprised 349 patients (FOLFOXIRI-bevacizumab, n=172; FOLFOX-bevacizumab, n=177). Median PFS was 12.4 months (95% CI 11.2 to 14.0) with FOLFOXIRI bevacizumab and 9.3 months (95% CI 8.5 to 10.7) with FOLFOX-bevacizumab (stratified HR, 0.64; 95% CI 0.49 to 0.82; p=0.0006). Grade≥3 adverse events were more common with FOLFOXIRI-bevacizumab 85.3% vs 75.1% with FOLFOX-bevacizumab (p=0.0178). Treatment-related deaths occurred in 8 (4.7%) and 6 (3.4%) patients, respectively. CONCLUSIONS First-line FOLFOXIRI-bevacizumab significantly improved PFS compared with FOLFOX-bevacizumab in patients with metastatic colorectal cancer and ≥3 CTCs at baseline, which indicate a poor prognosis. CTC count may be a useful non-invasive biomarker to assist with the selection of patients for intensive first-line therapy.

Abstract
AIM The TRICOLORE trial previously demonstrated that S-1 and irinotecan plus bevacizumab was non-inferior, based on progression-free survival (PFS), to 5-fluorouracil, leucovorin and oxaliplatin (mFOLFOX6)/capecitabine and oxaliplatin (CapeOX) plus bevacizumab as first-line chemotherapy for metastatic colorectal cancer (mCRC). Overall survival (OS) data were immature at the time of the primary analysis. METHODS In total, 487 patients from 53 institutions with previously untreated mCRC were randomly assigned (1:1) to receive either mFOLFOX6/CapeOX plus bevacizumab (control group) or S-1 and irinotecan plus bevacizumab (experimental group; 3- or 4-week regimen). The final OS data were analysed from follow-up data collected until 30th September 2017. RESULTS With a median follow-up period of 48.7 months, median survival times were 32.6 and 34.3 months (hazard ratio [HR]: 0.89, 95% confidence interval [CI]: 0.72-1.10, P = 0.293) and median PFS durations were 10.8 and 14.0 months in the control and experimental groups, respectively (HR: 0.86, 95% CI: 0.71-1.04, P < 0.0001 for non-inferiority). In patients with left-sided RAS wild-type tumours, median PFS durations were 11.4 and 16.9 months in the control and experimental groups, respectively (HR: 0.68, 95% CI: 0.48-0.96, P = 0.028). CONCLUSION S-1 and irinotecan plus bevacizumab resulted in comparable OS and non-inferior PFS with that of mFOLFOX6/CapeOX plus bevacizumab treatment as first-line chemotherapy for patients with mCRC. We recommend the use of S-1 and irinotecan plus bevacizumab as a standard first-line regimen independent of tumour sidedness or RAS status in mCRC. TRIAL REGISTRATION UMIN-CTR: 000007834.

Abstract
BACKGROUND Doublets plus antiepidermal growth factor receptors monoclonal antibodies (EGFRi) are widely considered the preferable first-line regimen in patients with left-sided RAS/BRAF wild-type metastatic colorectal cancer (mCRC), resulting superior in terms of activity and efficacy compared to doublets plus bevacizumab. However, data comparing doublet plus EGFRi and triplet plus bevacizumab are lacking, and the relative benefit of an intensive regimen plus an antiangiogenic backbone in this population is debated. METHODS This multicenter, retrospective study aimed at evaluating clinicians' attitude to triplet-bevacizumab and doublet-EGFRi as first-line regimen in patients with left-sided RAS/BRAF wild-type mCRC treated in clinical practice at 22 Oncology Units from March 2012 to October 2020. A random case-control matching was performed to compare activity (ORR), and effectiveness (PFS, OS, secondary resection rate of metastases with curative intent) between triplet-bevacizumab and doublet-EGFRi, on the basis of ECOG-PS, age, gender, and burden of disease. RESULTS A total of 718 patients were consecutively treated with doublet-EGFRi (686, 95.5%) or triplet-bevacizumab (32, 4.5%). After case-control matching, median PFS was 13.6 (95% CI, 8.9-31.7) and 16.1 (95% CI, 12.1-36.8) months (P= .621), while median OS was 30.2 (95% CI, 14.4-69.5) and 38.1 (95% CI, 33.1-101.1) months (P= .0283) in the doublet-EGFRi and the triplet-bevacizumab cohort, respectively. The ORR was 65.6% and 90.6% (P= .016), while the secondary resection rate was 18.8% and 46.9% (P= .016), in the doublet-EGFRi and the triplet-bevacizumab cohort, respectively. Triplet-bevacizumab was associated with a higher incidence of G3/G4 neutropenia (25.0% vs. 12.5%, P= .041). CONCLUSION Although a doublet-EGFRi remains the recommended upfront regimen in patients with left-sided RAS and BRAF wild-type mCRC, our real life data suggest a triplet-bevacizumab might be at least equally active and effective in properly selected cases.

Predictive Biomarkers of Oxaliplatin-Induced Peripheral Neurotoxicity. J Pers Med 2021; 11:jpm11070669.

Abstract
Oxaliplatin (OXA) is a platinum compound primarily used in the treatment of gastrointestinal cancer. OXA-induced peripheral neurotoxicity (OXAIPN) is the major non-hematological dose-limiting toxicity of OXA-based chemotherapy and includes acute transient neurotoxic effects that appear soon after OXA infusion, and chronic non-length dependent sensory neuronopathy symmetrically affecting both upper and lower limbs in a stocking-and-glove distribution. No effective strategy has been established to reverse or treat OXAIPN. Thus, it is necessary to early predict the occurrence of OXAIPN during treatment and possibly modify the OXA-based regimen in patients at high risk as an early diagnosis and intervention may slow down neuropathy progression. However, identifying which patients are more likely to develop OXAIPN is clinically challenging. Several objective and measurable early biomarkers for OXAIPN prediction have been described in recent years, becoming useful for informing clinical decisions about treatment. The purpose of this review is to critically review data on currently available or promising predictors of OXAIPN. Neurological monitoring, according to predictive factors for increased risk of OXAIPN, would allow clinicians to personalize treatment, by monitoring at-risk patients more closely and guide clinicians towards better counseling of patients about neurotoxicity effects of OXA.

The Use of Single-Agent Versus Multiple-Agent Concurrent Chemoradiotherapy in the Treatment of Locally Advanced Rectal Cancer. J Gastrointest Cancer 2021; 53:557-563. [PMID: 34196936 DOI: 10.1007/s12029-021-00657-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/18/2021] [Indexed: 10/21/2022]
Abstract
PURPOSE The use of concurrent chemoradiotherapy is frequently recommended in the treatment of locally advanced rectal cancer; however, the ideal chemotherapy regimen remains unknown, and there is variability in chemotherapy agents used among different institutions. We sought to examine differences in overall survival between patients receiving single versus multiple-agent concurrent chemoradiotherapy. METHODS The National Cancer Database was used to identify 31,025 patients with rectal cancer who received concurrent chemoradiotherapy between 01/2006 and 12/2016. We compared patients who received single-agent chemotherapy with those who received multiple-agent concurrent chemoradiotherapy. The primary outcome of interest was overall survival. The groups were compared using univariate analysis and Cox proportional hazard models to adjust for potential confounding factors. RESULTS 18,544 patients received single-agent and 12,481 patients received multiple-agent chemotherapy. The former were older with more comorbidities as evidenced by their higher Charlson-Deyo Scores. Those receiving multiple-agent chemotherapy were more likely to have clinical stage III disease (52.9% vs 43.3%, p < 0.001) and less likely to have well-differentiated cancer (6.9% vs 7.7%, p < 0.001). The rates of negative resection margin were identical (p = 0.225) between the two groups. On multivariable analysis after adjusting for comorbidities, radiation dose, and resection margins, single-agent chemotherapy was associated with worse overall survival (HR 1.09, 95% CI 1.057-1.124, p < 0.001). CONCLUSION Multiple-agent chemoradiotherapy is associated with improved overall survival in locally advanced rectal cancer; however, chemotherapy regimen does not affect resection margins. The modest overall survival benefit with multiple-agent chemotherapy must be balanced with the potential associated toxicity.

LESSONS LEARNED Preclinical studies have demonstrated that Src inhibition through dasatinib synergistically enhances the antitumor effects of oxaliplatin. In this phase II, single-arm study, FOLFOX with dasatinib in previously untreated patients with mPC only showed only modest clinical activity, with a progressive-free survival of 4 months and overall survival of 10.6 months. Continued investigation is ongoing to better understand the role of Src inhibition with concurrent 5-fluorouracil and oxaliplatin in a subset of exceptional responders. BACKGROUND Src tyrosine kinase activity is overexpressed in many human cancers, including metastatic pancreatic cancer (mPC). Dasatinib is a potent inhibitor of Src family of tyrosine kinases. This study was designed to investigate whether dasatinib can synergistically enhance antitumor effects of FOLFOX regimen (FOLFOX-D). METHODS In this single-arm, phase II study, previously untreated patients received dasatinib 150 mg oral daily on days 1-14, oxaliplatin 85 mg/m2 intravenous (IV) on day 1 every 14 days, leucovorin (LV) 400 mg/m2 IV on day 1 every 14 days, 5-fluorouracil (5-FU) bolus 400 mg/m2 on day 1 every 14 days, and 5-FU continuous infusion 2,400 mg/m2 on day 1 every 14 days. Primary endpoint was progression-free survival (PFS) with preplanned comparison to historical controls. RESULTS Forty-four patients enrolled with an estimated median PFS of 4.0 (95% confidence interval [CI], 2.3-8.5) months and overall survival (OS) of 10.6 (95% CI, 6.9-12.7) months. Overall response rate (ORR) was 22.7% (n = 10): one patient (2.3%) with complete response (CR) and nine patients (20.5%) with partial response (PR). Fifteen patients (34.1%) had stable disease (SD). Nausea was the most common adverse event (AE) seen in 35 patients (79.5%). CONCLUSION The addition of dasatinib did not appear to add incremental clinical benefit to FOLFOX in untreated patients with mPC.
