Phase II Study of 5-Fluorouracil, Oxaliplatin plus Dasatinib ( FOLFOX-D) in First-Line Metastatic Pancreatic Adenocarcinoma. Oncologist 2021; 26:825-e1674. [PMID: 34101295 DOI: 10.1002/onco.13853] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Accepted: 05/25/2021] [Indexed: 11/09/2022] Open
Abstract
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.

A Community Hospital-Based Study: A Prespecified Neutrophil Count with Adjuvant m FOLFOX6 Associated with Increased Delays, Increased G-CSF Use, and Reduced Dose Intensity. Cancer Manag Res 2021; 13:4087-4094. [PMID: 34040446 PMCID: PMC8141389 DOI: 10.2147/cmar.s307713] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2021] [Accepted: 04/28/2021] [Indexed: 12/20/2022] Open
Abstract
Purpose To look at how the absolute neutrophil count (ANC) is used by community oncologists as the main factor in ordering adjuvant mFOLFOX6 for colorectal cancer. This study reports on how this decision impacts chemotherapy delays, effects received dose intensity (RDI), and increases the use of granulocyte-colony-stimulating factor (G-CSF). Methods A retrospective chart review was conducted for all patients receiving adjuvant mFOLFOX6 for colorectal cancer at a two-site community hospital in Toronto, Ontario, Canada, between July 2013 and March 2019. Seven physicians treated 140 patients, who made 1636 clinic visits to receive 1461 cycles of prescribed chemotherapy. Results The mean ANC per physician associated with a decision to give chemotherapy ranged from 1.05×109/L (95% CI 0.98-1.13×109/L) to 1.5x109/L with a decision to delay if the ANC was lower. Subsequent cycles were then supported by G-CSF with very similar ANC decision levels for dose delay. Physicians were more likely to prescribe chemotherapy with higher pretreatment ANC, r=0.3 (p<0.000). G-CSF was used in 24.6% of cycles and usage had grown to 44.2% by the 12th cycle; physician use ranged from 0.36% to 54.2% of cycles. Secondary prophylaxis was the indication in 94.7% of cases. There was an inverse relationship between the frequency of G-CSF use and the RDI of continuous infusion 5FU, r=-0.26 (p<0.001). There were delays for 8.8% of visits for cycles not supported by G-CSF and, surprisingly, 15.9% of visits for cycles supported by G-CSF. Neutropenia caused 61.6% of delays for chemotherapy cycles not supported by G-CSF and 44.1% for cycles supported by G-CSF. Conclusion Physicians required a pretreatment ANC of 1.05-1.5×109/L before prescribing mFOLFOX6 chemotherapy. When ANC was low, a dose delay and secondary prophylaxis with G-CSF failed to consistently achieve the much sought after ANC. This then caused more delay, reduced RDI and increased expense for both patients and the system. Fewer delays, less G-CSF and increased RDI would have resulted with reduced reliance on ANC and adoption of chemotherapy dose reduction.

Abstract
BACKGROUND FOLFOX therapy, a standard treatment for colorectal cancer (CRC), causes a rare, but serious adverse event, hyperammonemia. However, the risk factors of hyperammonemia remain unknown. METHODS We examined 74 patients who received mFOLFOX6 therapy with or without biologics for CRC between April 2013 and March 2018 in Yaizu City Hospital. Clinicopathological factors were retrospectively reviewed in association with hyperammonemia, and risk factors of hyperammonemia during mFOLFOX6 therapy were analyzed in 32 patients with the available data. RESULTS Seven patients developed hyperammonemia, with onset exclusively on day 2 or 3 in the first cycle of therapy. They were treated with branched chain amino acid administration and hydration; however, one patient with stage G4 chronic kidney disease (CKD) died. By multivariate analysis, estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 was independently associated with hyperammonemia during FOLFOX therapy (odds ratio: 9.0, p = 0.040). CONCLUSIONS Reduced eGFR is considered a risk factor of developing hyperammonemia during FOLFOX therapy. Serum ammonia levels should be monitored especially during the first cycle of FOLFOX therapy in patients with CKD stage G3 or higher.

Hepatic Arterial Infusion Chemotherapy of Oxaliplatin, Fluorouracil, and Leucovorin With or Without Sorafenib as Initial Treatment for Advanced Hepatocellular Carcinoma. Front Oncol 2021; 11:619461. [PMID: 34055599 PMCID: PMC8149911 DOI: 10.3389/fonc.2021.619461] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Accepted: 04/23/2021] [Indexed: 12/17/2022] Open
Abstract
Purpose Our previous study showed that hepatic arterial infusion chemotherapy (HAIC) using oxaliplatin, fluorouracil, and leucovorin (FOLFOX) plus sorafenib provided a significant survival benefit over sorafenib for advanced hepatocellular carcinoma. However, it is unclear whether the survival benefit should be attributed to the synergism between HAIC and sorafenib or just HAIC alone. We aim to compare HAIC using FOLFOX plus sorafenib with HAIC alone in patients with advanced hepatocellular carcinoma. Materials and Methods This was a retrospective study including 225 eligible patients treated with HAIC using FOLFOX (HAIC alone group, n=126, oxaliplatin 85 mg/m², leucovorin 400 mg/m², fluorouracil bolus 400 mg/m² and 2400 mg/m² for 46 hours, every 3 weeks) alone or HAIC plus sorafenib (soraHAIC group, n=99, sorafenib 400 mg twice daily). Survival curves were calculated by the Kaplan-Meier method, and propensity-score matching was used to reduce bias. Results The soraHAIC group showed a longer overall survival (12.9 [95% CI, 10.4-15.4] vs. 10.5 [95% CI, 9.5-11.5] months, HR=0.71 [95% CI, 0.53-0.96]; P=0.025), a better progression free survival (7.0 [95% CI, 5.3-8.8] vs. 5.3 [95% CI, 3.5-7.1] months, HR=0.76 [95% CI, 0.58-0.99]; P=0.046), and a higher disease control rate (RECIST 1.1: 74.8% vs. 61.1%, P=0.030) than the HAIC alone group. In multivariate analysis, soraHAIC was an independent favor factor for survival. In terms of the grade 3/4 adverse event, hand–foot skin reaction was more frequent in the soraHAIC group than the HAIC alone group. In the propensity-score matched cohorts (93 pairs), the overall survival, the progression free survival and disease control rates in the soraHAIC group were also better than those in the HAIC group (P<0.05). Conclusion HAIC plus sorafenib may improve overall survival and progression free survival compared with HAIC alone as initial treatment for advanced hepatocellular carcinoma.

Abstract
BACKGROUND In the management of peritoneal metastases from colon and rectal cancer, the most favorable results are reported with an aggressive combined treatment on patients who have a small extent of the disease. A test to detect occult peritoneal metastases would greatly facilitate the management of this component of colorectal dissemination. METHODS Currently, the standard test by which to confirm the diagnosis of the peritoneal spread of colorectal cancer is peritoneal cytology. To study the utility of this test, we gathered information from patients with biopsy-proven peritoneal metastases. The clinical, histologic, and treatment-related features of these patients at the time of a cytoreductive surgery were statistically correlated with the results of the peritoneal cytology test. RESULTS Forty-nine patients with colorectal cancer peritoneal metastases and a peritoneal cytology determination at the time of a cytoreductive surgery were available for analysis. Twenty-eight patients (55.1%) had a positive test. Patients with a high peritoneal cancer index and mucinous histology were most likely to have positive peritoneal cytology. CONCLUSION Peritoneal cytology identified patients with mucinous histology and a large extent of disease but was consistently negative in patients who had a small extent of disease compatible with a favorable response to treatment.

Abstract
BACKGROUND At present, surgery is still the main treatment for colorectal cancer, and postoperative chemotherapy and targeted drug therapy are used as auxiliary treatments. Since targeted drugs are restricted by genetic and price factors, chemotherapy drugs are still the first choice for treatment. Many studies have demonstrated that drug combination can inhibit the growth of cancer cells in more ways, and its efficacy is better than single drug chemotherapy.
AIM To investigate the application value of irinotecan-assisted FOLFOX chemotherapy in colorectal cancer.
METHODS A total of 92 patients with colorectal cancer treated at our hospital from March 2017 to February 2019 were selected and divided into a study group (n = 46) and a control group (n = 46) based on a simple random number table. On the basis of targeted therapy, the control group received the FOLFOX regimen, and the study group received irinotecan-assisted FOLFOX chemotherapy regimen. Tumor control rate, serum levels of tumor markers, miR-200a, miR-190, serum transforming growth factor-α (TGF-α), and insulin-like growth factor Ⅱ (IGF-Ⅱ), and the incidence of toxic and side effects were compared between the two groups. The patient were followed for 12 mo, and the survival rates of the two groups were calculated.
RESULTS There was no significant difference in the tumor control rate between the study group (71.74%) and control group (65.22%; P > 0.05). After treatment, serum levels of CEA, CA125, CA199, CA72-4, TGF-α, and IGF-Ⅱ in the study group were significantly lower than those of the control group (P < 0.05), and the expression of serum miR-200a and miR-190 in the study group was significantly higher than that of the control group (P < 0.05). No grade 4 toxic and side effects occurred in either group, and there was no significant difference in the incidence of toxic and side effects between the two groups (P > 0.05). There was no significant difference in survival rates at 6 mo, 9 mo, and 12 mo after treatment between the study group (95.56%, 88.89%, and 80.00%) and control group (91.11%, 75.56%, and 64.44%; P > 0.05 for all).
CONCLUSION The combination of FOLFOX chemotherapy and irinotecan in the treatment of colorectal cancer can reduce the serum levels of tumor markers, TGF-α, and IGF-Ⅱ, regulate the expression of miR-200a andmiR-190, but does not increase the risk of adverse reactions.

Abstract
Background Hepatic artery infusion chemotherapy (HAIC) and anti-programmed cell death protein-1 (PD-1) immunotherapy have shown promising outcomes in patients with advanced hepatocellular carcinoma (HCC), respectively. However, the combination of the two treatments has not been reported. In this study, we compared the efficacy of HAIC combined with anti-PD-1 immunotherapy (HAICAP) and HAIC in patients with advanced HCC. Methods Between November 2018 and December 2019, advanced HCC patients that were treated with either HAICAP or HAIC were retrospectively recruited and reviewed for eligibility. Efficacy was evaluated according to tumor response and survival. Results As a result, 229 patients were included in this study. Patients were divided into HAICAP group (n = 81) and HAIC group (n = 148) accordingly. The follow-up time ranged from 1.0 to 21.6 months, with a median of 11.0 months. The median overall survival was 18.0 months in the HAICAP group and 14.6 months in the HAIC group (p = 0.018; HR = 0.62; 95% CI 0.34–0.91). The median progression-free survival was 10.0 months in the HAICAP group and 5.6 months in the HAIC group (p = 0.006; HR = 0.65; 95% CI 0.43–0.87). The disease control rate in overall response (83% vs 66%; p = 0.006) and intrahepatic response (85% vs 74%, respectively; p = 0.045) were higher in the HAICAP group than in the HAIC group. Conclusion In comparison to HAIC, HAICAP was associated with a better treatment response and survival benefits for patients with advanced HCC.

Abstract
Background Lenvatinib is the first-line treatment for advanced hepatocellular carcinoma, but prognosis is still unsatisfactory. Recently, hepatic arterial infusion chemotherapy (HAIC), and immune checkpoint inhibitors showed promising results for advanced hepatocellular carcinoma. Considering different anti-malignancy mechanisms, combining these three treatments may improve outcomes. This study aimed to compare the efficacy and safety of lenvatinib, toripalimab, plus HAIC versus lenvatinib for advanced hepatocellular carcinoma. Methods This was a retrospective study including patients treated with lenvatinib [8 mg (⩽60 kg) or 12 mg (>60 kg) once daily] or lenvatinib, toripalimab plus HAIC [LeToHAIC group, lenvatinib 0-1 week prior to initial HAIC, 240 mg toripalimab 0-1 day prior to every HAIC cycle, and HAIC with FOLFOX regimen (oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, 5-fluorouracil bolus 400 mg/m2 on day 1, and 5-fluorouracil infusion 2400 mg/m2 for 46 h, every 3 weeks)]. Progression-free survival, overall survival, objective response rate, and treatment-related adverse events were compared. Results From February 2019 to August 2019, 157 patients were included in this study: 71 in the LeToHAIC group and 86 in the lenvatinib group. The LeToHAIC group showed longer progression-free survival (11.1 versus 5.1 months, p < 0.001), longer overall survival (not reached versus 11 months, p < 0.001), and a higher objective response rate (RECIST: 59.2% versus 9.3%, p < 0.001; modified RECIST: 67.6% versus 16.3%, p < 0.001) than the lenvatinib group. In addition, 14.1% and 21.1% of patients in the LeToHAIC group achieved complete response of all lesions and complete response of the intrahepatic target lesions per modified RECIST criteria, respectively. Grade 3/4 treatment-related adverse events that were more frequent in the LeToHAIC group than in the lenvatinib group included neutropenia (8.5% versus 1.2%), thrombocytopenia (5.6% versus 0), and nausea (5.6% versus 0). Conclusions Lenvatinib, toripalimab, plus HAIC had acceptable toxic effects and might improve survival compared with lenvatinib alone in advanced hepatocellular carcinoma.

Abstract
Background Hepatic arterial infusion (HAI) of oxaliplatin, leucovorin, and fluorouracil (FOLFOX) plus sorafenib has a more desirable effect versus sorafenib for hepatocellular carcinoma (HCC) patients with portal vein invasion. However, considering the high cost of hepatic arterial infusion of chemotherapy (HAIC), this study evaluated the cost-effectiveness of HAIC plus sorafenib (SoraHAIC) versus standard care for HCC patients from the Chinese health system perspective. Methods A Markov multi-state model was constructed to simulate the disease course and source consumption of SoraHAIC. Costs of primary therapeutic drugs were calculated based on the national bid price, and hepatic artery catheterization fee was collected from the Fujian Provincial Price Bureau. Clinical data, other costs, and utility values were extracted from references. Primary outcomes included life-years (LYs), quality-adjusted life years (QALYs) and incremental cost-effectiveness ratio (ICER). The robustness of model was verified by uncertainty sensitivity analyses. Results SoraHAIC gained 1.18 QALYs (1.68 LYs) at a cost of $65,254, while the effectiveness and cost of sorafenib were 0.52 QALYs (0.79 LYs) and $14,280, respectively. The ICER of SoraHAIC vs sorafenib was $77,132/QALY ($57,153/LY). Parameter that most influenced the ICER was utility of PFS state. The probabilistic sensitivity analysis (PSA) showed that SoraHAIC was not cost-effective in the WTP threshold of 3*Gross Domestic Product (GDP) per capita of China ($30,492/QALY). But about 38.8% of the simulations were favorable to SoraHAIC at the WTP threshold of 3*GDP per capita of Beijing ($72,000/QALY). When 3*GDP per capita of Fujian ($47,285/QALY) and Gansu Province ($14,595/QALY) were used as WTP threshold, the acceptability of SoraHAIC was 0.3% and 0%, respectively. Conclusions The study results indicated that SoraHAIC was not cost-effective in medium-, and low-income regions of China. In developed areas of China (Beijing), there was a 38.8% probability that the SoraHAIC regimen would be cost-effective.

Abstract
The most common treatment for advanced gastric cancer (AGC) is systemic chemotherapy. The standard treatment for advanced gastric cancer differs worldwide. In Japan, two phase III clinical trials demonstrated the non-inferiority of S-1 compared with 5-fluorouracil (5-FU) and superiority of cisplatin plus S-1 (CS), compared with S-1, with respect to overall survival (SPIRITS trial). Oxaliplatin (L-OHP) has a favorable toxicity profile compared with cisplatin; hence, a phase III clinical trial (G-SOX trial) demonstrated the progression-free survival (PFS) and overall survival in CS was 5.4 and 13.1 months and those in SOX was 5.5 and 14.1 months, respectively. Serious adverse events were more frequently seen in CS than in SOX. So, SOX is as effective as CS for advanced gastric cancer with favorable safety profile. After the publication of this G-SOX trial, the combination of oral or intravenous 5-FU and various doses of L-OHP have been reported. And FOLFOX6 regimen (FOLFOX: a combination of 1-LV and FU with L-OHP) was approved for the treatment of AGC in Japan in 2017. FOLFOX was promising for patients with severe peritoneal metastasis from AGC, because the FOLFOX regimen does not require hydration and does not include oral agents. This review summarizes the efficacy and safety of doublet combinations of platinum and fluoropyrimidines using L-OHP for advanced gastric cancer.

Abstract
BACKGROUND 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) has activity in pancreatic neuroendocrine tumors (pNETs), but its use is limited, partly because of toxicities. pNETs can often become aggressive over time. We evaluated the efficacy of FOLFOX in patients with aggressive pNETs who had progressed after capecitabine plus temozolomide (cap/tem) among other treatments. MATERIALS AND METHODS This was a retrospective study of all patients with well-differentiated metastatic pNETs, treated at an academic cancer center between January 2008 and June 2019, who received FOLFOX and had received cap/tem in the past. The primary endpoint was objective response rate. RESULTS Thirty-one patients met eligibility criteria. Twenty-five received FOLFOX, and six received FOLFOX with bevacizumab. Patients were heavily pretreated, having received a median of three prior lines of systemic therapy prior to FOLFOX (range, 1-8). Three (9.7%) patients had grade [G]1 tumors, 16 (51.6%) had G2, and 6 (19.4%) had G3, and grade was unspecified in 6 (19.4%) patients. Fourteen (45.2%) exhibited a best response of partial radiographic response per RECIST 1.1 criteria, 15 (48.4%) stable disease, and 2 (6.4%) progressive disease; overall response rate was 45.2% and disease control rate was 93.5%. Median progression-free survival was 6 months (95% confidence interval [CI], 5.0-7.0), and median overall survival was 16 months from onset of study treatment (95% CI, 11.3-20.7) and 67 months from date of diagnosis (95% CI, 49.8-84.2). Median duration of treatment was 3 months, and median duration of response was 2 months. Toxicity profile was consistent with known adverse events associated with this regimen. CONCLUSION FOLFOX is active in aggressive, heavily pretreated pNETs that have progressed on prior cap/tem chemotherapy; response durations are relatively short. IMPLICATIONS FOR PRACTICE FOLFOX chemotherapy has robust activity in patients with rapidly progressive, heavily pretreated pancreatic neuroendocrine tumors (NETs), a setting in which few, if any, other options are likely to be effective. Durations of response, however, are relatively short, and new treatments are urgently needed for patients with aggressive transformation of pancreatic NETs.

Abstract
Background Treatment options for pancreatic ductal adenocarcinoma (PDAC) are limited and checkpoint blockade inhibitors have been disappointing in this disease. Pegilodecakin has demonstrated single agent anti-tumor activity in immune-sensitive tumors. Phase 1 and preclinical data indicate synergy of pegilodecakin with 5-FU and platins. We assessed the safety and activity of pegilodecakin+FOLFOX in patients with PDAC. Methods IVY (NCT02009449) was an open-label phase 1b trial in the United States. Here we report on all enrolled patients from cohort C. Heavily pretreated patients were treated with pegilodecakin (self-administered subcutaneously daily at 2.5, 5, or 10 μg/kg) + 5-flurouracil/leucovorin/oxaliplatin (FOLFOX), dosed per manufacturers prescribing information, until tumor progression. Eligible patients had measurable disease per immune-related response criteria (irRC), were ≥ 18 years of age, and had ECOG performance status of 0 or 1. Patients were evaluated for primary(safety) and secondary (tumor response per irRC) endpoints. Results From 5 August 2014-12 July 2016, 39 patients enrolled in cohort C. All patients were evaluable for safety. In this advanced population, regimen had manageable toxicities with no immune-related adverse events (irAEs) greater than grade 1. The most common grade 3/4/5 TEAEs were thrombocytopenia (21[53.8%] of 39) and anemia (17[43.6%] of 39). In evaluable PDAC patients, the best overall response of pegilodecakin+FOLFOX was 3(14%) with CRs in 2(9%) patients. Conclusions Pegilodecakin+FOLFOX had an acceptable tolerability profile in PDAC, with no substantial irAEs seen, and promising efficacy with the combination yielding a 2-year OS of 24% (95% CI 10-42). These data led to the phase 3 study with pegilodecakin+FOLFOX as second-line therapy of PDAC (SEQUOIA).

[PMID: 33585448 PMCID: PMC7876414 DOI: 10.3389/fcell.2020.609832] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Accepted: 12/21/2020] [Indexed: 12/19/2022] Open
Abstract
Oxaliplatin, fluorouracil plus leucovorin (FOLFOX) regimen is the first-line chemotherapy of patients with metastatic colorectal cancer (mCRC). However, studies are limited regarding long non-coding RNAs (lncRNAs) associated with FOLFOX chemotherapy response and prognosis. This study aimed to identify lncRNAs associated with FOLFOX chemotherapy response and prognosis in mCRC patients and to construct a predictive model. We analyzed lncRNA expression in 11 mCRC patients treated with FOLFOX chemotherapy before surgery (four sensitive, seven resistant) by Gene Array Chip. The top eight lncRNAs (AC007193.8, CTD-2008N3.1, FLJ36777, RP11-509J21.4, RP3-508I15.20, LOC100130950, RP5-1042K10.13, and LINC00476) for chemotherapy response were identified according to weighted correlation network analysis (WGCNA). A competitive endogenous RNA (ceRNA) network was then constructed. The crucial functions of the eight lncRNAs enriched in chemotherapy resistance were mitogen-activated protein kinase (MAPK) and proteoglycans signaling pathway. Receiver operating characteristic (ROC) analysis demonstrated that the eight lncRNAs were potent predictors for chemotherapy resistance of mCRC patients. To further identify a signature model lncRNA chemotherapy response and prognosis, the validation set consisted of 196 CRC patients from our center was used to validate lncRNAs expression and prognosis by quantitative PCR (qPCR). The expression of the eight lncRNAs expression between CRC cancerous and adjacent non-cancerous tissues was also verified in the validation data set to determine the prognostic value. A generalized linear model was established to predict the probability of chemotherapy resistance and survival. Our findings showed that the eight-lncRNA signature may be a novel biomarker for the prediction of FOLFOX chemotherapy response and prognosis of mCRC patients.

A Mathematical Model to Estimate Chemotherapy Concentration at the Tumor-Site and Predict Therapy Response in Colorectal Cancer Patients with Liver Metastases. Cancers (Basel) 2021; 13:cancers13030444. [PMID: 33503971 PMCID: PMC7866038 DOI: 10.3390/cancers13030444] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Accepted: 01/21/2021] [Indexed: 12/22/2022] Open
Abstract
Simple Summary It is known that drug transport barriers in the tumor determine drug concentration at the tumor site, causing disparity from the systemic (plasma) drug concentration. However, current clinical standard of care still bases dosage and treatment optimization on the systemic concentration of drugs. Here, we present a proof of concept observational cohort study to accurately estimate drug concentration at the tumor site from mathematical modeling using biologic, clinical, and imaging/perfusion data, and correlate it with outcome in colorectal cancer liver metastases. We demonstrate that drug concentration at the tumor site, not in systemic circulation, can be used as a credible biomarker for predicting chemotherapy outcome, and thus our mathematical modeling approach can be applied prospectively in the clinic to personalize treatment design to optimize outcome. Abstract Chemotherapy remains a primary treatment for metastatic cancer, with tumor response being the benchmark outcome marker. However, therapeutic response in cancer is unpredictable due to heterogeneity in drug delivery from systemic circulation to solid tumors. In this proof-of-concept study, we evaluated chemotherapy concentration at the tumor-site and its association with therapy response by applying a mathematical model. By using pre-treatment imaging, clinical and biologic variables, and chemotherapy regimen to inform the model, we estimated tumor-site chemotherapy concentration in patients with colorectal cancer liver metastases, who received treatment prior to surgical hepatic resection with curative-intent. The differential response to therapy in resected specimens, measured with the gold-standard Tumor Regression Grade (TRG; from 1, complete response to 5, no response) was examined, relative to the model predicted systemic and tumor-site chemotherapy concentrations. We found that the average calculated plasma concentration of the cytotoxic drug was essentially equivalent across patients exhibiting different TRGs, while the estimated tumor-site chemotherapeutic concentration (eTSCC) showed a quadratic decline from TRG = 1 to TRG = 5 (p < 0.001). The eTSCC was significantly lower than the observed plasma concentration and dropped by a factor of ~5 between patients with complete response (TRG = 1) and those with no response (TRG = 5), while the plasma concentration remained stable across TRG groups. TRG variations were driven and predicted by differences in tumor perfusion and eTSCC. If confirmed in carefully planned prospective studies, these findings will form the basis of a paradigm shift in the care of patients with potentially curable colorectal cancer and liver metastases.

Escalante PI, Quiñones LA, Contreras HR. Epithelial-Mesenchymal Transition and MicroRNAs in Colorectal Cancer Chemoresistance to FOLFOX. Pharmaceutics 2021; 13:pharmaceutics13010075. [PMID: 33429840 PMCID: PMC7827270 DOI: 10.3390/pharmaceutics13010075] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Revised: 12/21/2020] [Accepted: 12/25/2020] [Indexed: 12/14/2022] Open
Abstract
The FOLFOX scheme, based on the association of 5-fluorouracil and oxaliplatin, is the most frequently indicated chemotherapy scheme for patients diagnosed with metastatic colorectal cancer. Nevertheless, development of chemoresistance is one of the major challenges associated with this disease. It has been reported that epithelial-mesenchymal transition (EMT) is implicated in microRNA-driven modulation of tumor cells response to 5-fluorouracil and oxaliplatin. Moreover, from pharmacogenomic research, it is known that overexpression of genes encoding dihydropyrimidine dehydrogenase (DPYD), thymidylate synthase (TYMS), methylenetetrahydrofolate reductase (MTHFR), the DNA repair enzymes ERCC1, ERCC2, and XRCC1, and the phase 2 enzyme GSTP1 impair the response to FOLFOX. It has been observed that EMT is associated with overexpression of DPYD, TYMS, ERCC1, and GSTP1. In this review, we investigated the role of miRNAs as EMT promotors in tumor cells, and its potential effect on the upregulation of DPYD, TYMS, MTHFR, ERCC1, ERCC2, XRCC1, and GSTP1 expression, which would lead to resistance of CRC tumor cells to 5-fluorouracil and oxaliplatin. This constitutes a potential mechanism of epigenetic regulation involved in late-onset of acquired resistance in mCRC patients under FOLFOX chemotherapy. Expression of these biomarker microRNAs could serve as tools for personalized medicine, and as potential therapeutic targets in the future.

Abstract
BACKGROUND Doublets plus anti-epidermal growth factor receptors (EGFRs) are the preferred upfront option for patients with left-sided RAS/BRAF wild-type metastatic colorectal cancer (mCRC). Initial therapy with FOLFOXIRI-bevacizumab is superior to doublets plus bevacizumab independently from primary tumor sidedness and RAS/BRAF status. No randomized comparison between FOLFOXIRI-bevacizumab versus doublets plus anti-EGFRs is available in left-sided RAS/BRAF wild-type mCRC. MATERIALS AND METHODS We selected patients with left-sided RAS and BRAF wild-type mCRC treated with first-line FOLFOX-panitumumab or FOLFOXIRI-bevacizumab in five randomized trials: Valentino, TRIBE, TRIBE2, STEAM, and CHARTA. A propensity score-based analysis was performed to compare FOLFOXIRI-bevacizumab with FOLFOX-panitumumab. RESULTS A total of 185 patients received FOLFOX-panitumumab and 132 received FOLFOXIRI-bevacizumab. Median progression-free survival (PFS) and median overall survival (OS) were 13.3 and 33.1 months in the FOLFOXIRI-bevacizumab group compared with 11.4 and 30.3 months in the FOLFOX-panitumumab group (propensity score-adjusted hazard ratio (HR) for PFS, 0.82; 95% confidence interval (CI), 0.64-1.04; p = .11; propensity score-adjusted HR for OS, 0.80; 95% CI, 0.59-1.08; p = .14). No significant differences in overall response rate and disease control rate were observed. A statistically nonsignificant difference in favor of FOLFOXIRI-bevacizumab was observed for OS after secondary resection of metastases. Chemotherapy-related adverse events were more frequent in the FOLFOXIRI-bevacizumab group, with specific regard to grade 3 and 4 neutropenia (48% vs. 26%, adjusted p = .001). CONCLUSION Although randomized comparison is lacking, both FOLFOXIRI-bevacizumab and FOLFOX-panitumumab are valuable treatment options in left-sided RAS/BRAF wild-type mCRC. IMPLICATIONS FOR PRACTICE A propensity score-based analysis of five trials was performed to compare FOLFOX-panitumumab versus FOLFOXIRI-bevacizumab in left-sided RAS/BRAF wild-type metastatic colorectal cancer (mCRC). No significant differences were observed, but FOLFOXIRI-bevacizumab achieved numerically superior survival outcomes versus FOLFOX-panitumumab. Chemotherapy-related adverse events were more frequent in the FOLFOXIRI-bevacizumab group. These observations suggest that although doublet chemotherapy plus anti-EGFRs remains the preferred treatment in patients with left-sided RAS/BRAF wild-type mCRC, FOLFOXIRI-bevacizumab is a valuable option able to provide similar, if not better, outcomes at the price of a moderate increase in toxicity and may be adopted based on patients' preference and potential impact on quality of life.

Abstract
BACKGROUND Lenvatinib combined with programmed cell death protein-1 (PD-1) inhibitors has resulted in good survival outcomes in the treatment of unresectable hepatocellular carcinoma (HCC). Hepatic artery infusion chemotherapy (HAIC) has also attracted attention due to its high response rates and favorable survival for advanced HCC patients. The present study aimed to compare the efficacy of HAIC combined with PD-1 inhibitors plus lenvatinib (HPL) and PD-1 inhibitors plus lenvatinib (PL) in patients with advanced HCC. METHODS Between July 2018 and December 2019, patients diagnosed with advanced HCC who initially received HPL or PL treatment were reviewed for eligibility. Efficacy was evaluated according to tumor response and survival. RESULTS In total, 70 patients met the criteria and were included in the present study, and they were divided into the HPL group (n = 45) and PL group (n = 25). The overall response rate (40.0 vs. 16.0%, respectively; p = 0.038) and disease control rate (77.6 vs. 44.0%, respectively; p < 0.001) were higher in the HPL group than in the PL group. The median overall survival was 15.9 months in the HPL group and 8.6 months in the PL group (p = 0.0015; HR = 0.6; 95% CI 0.43-0.83). The median progression-free survival was 8.8 months in the HPL group and 5.4 months in the PL group (p = 0.0320; HR = 0.74; 95% CI 0.55-0.98). CONCLUSION Compared to PL, HPL was associated with a significantly better treatment response and survival benefits for patients with advanced HCC.

Abstract
BACKGROUND The IDEA collaboration showed that the type and duration of adjuvant chemotherapy in stage III colon cancer (CC) could be adjusted according to the schedule of chemotherapy and the level of risk. We aimed at evaluating the implementation of IDEA's results in real-life practice for stage III CC. MATERIAL AND METHODS All clinicians registered in the French oncology cooperative groups GERCOR, FFCD, and UNICANCER GI mailing lists were invited to participate to an online anonymized nationwide survey from January 30, 2019 to March 31, 2019. Proportions were compared using the χ2 test. RESULTS A total of 213 physicians answered the survey. Of these, 173 (81%) considered that 3 months of adjuvant chemotherapy was the new standard of care for low-risk (pT1-3/N1) stage III CC, and 99% considered that 6 months remained the standard of care for high-risk (pT4 and/or pN2) stage III CC. In patients under 70 years, capecitabine and oxaliplatin (CAPOX) for 3 months was prescribed by 74% of the participants in low-risk CC, whereas 6 months of 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) was preferred for high-risk CC in 94% of cases. For patients over 70 years with good performance status and no comorbidities, 172 (81%) physicians prescribed oxaliplatin-based chemotherapy for low-risk CC (3 months, 144 of 172%; 88%), and 200 (94%) physicians prescribed oxaliplatin-based adjuvant chemotherapy for high-risk CC (6 months, 199 of 200%; 99.5%). CONCLUSIONS The IDEA results have been practice-changing as French physicians have implemented 3 months of CAPOX for patients with low-risk stage III CC, substituting from 6 months of FOLFOX, which remains the preferred regimen for high-risk patients.

Abstract
BACKGROUND Selinexor is an oral Selective Inhibitor of Nuclear Export compound that specifically blocks Chromosomal Region Maintenance protein 1. OBJECTIVE To evaluate the safety and tolerability of escalating doses of selinexor plus 5-fluorouracil, leucovorin and oxaliplatin (mFOLFOX6) in metastatic colorectal cancer (mCRC) patients. METHODS In this multicenter phase I trial, mCRC patients, eligible for oxaliplatin-based treatment, were enrolled to receive oral selinexor on days 1, 3, and 8 plus mFOLFOX6 every two weeks. Primary endpoint was the maximum tolerated dose. Secondary endpoints were toxicity, overall response rate, progression free survival, and overall survival. RESULTS Overall, 10 patients were enrolled, who had prior treatment with oxaliplatin (6/10), irinotecan (8/10), bevacizumab (6/10) or anti-EGFR therapy (5/10). Four consecutive patients received 40 mg selinexor plus mFOLFOX6. All four experienced dose-limiting toxicities and withdrew from the study after a median of two cycles. Thus, this dose level was regarded as toxic and no further patients were evaluated at this dose. Six patients were enrolled with 20 mg selinexor plus mFOLFOX6. Despite better tolerability, four patients withdrew (patient wish) after the first cycle and only two patients continued until disease progression. Most commonly reported treatment emergent adverse events were nausea (80%), diarrhea (70%), vomiting (60%), fatigue (60%), anorexia (40%), and impaired vision (40%). Due to the short treatment exposure, no relevant clinical activity was observed. CONCLUSION In patients with metastatic colorectal cancer, selinexor on this dose schedule plus mFOLFOX6 was not tolerable. Other dosing schedules or combinations may be evaluated. Clinical trial identifier NCT02384850.

Abstract
BACKGROUND Although occasioned through different mechanisms, the potential neurotoxicity and also haematological toxicity of nab-paclitaxel and oxaliplatin-based chemotherapy regimen were studied in this trial, which aimed to determine the maximum-tolerated dose (MTD) and to evaluate safety and efficacy of the combination in a sequential regimen of nab-paclitaxel, gemcitabine (GEM) and modified FOLFOX (mFOLFOX) in untreated patients with metastatic pancreatic ductal adenocarcinoma (PDAC). MATERIALS AND METHODS Treatment consisted of nab-paclitaxel (125/100 mg/m2) plus GEM (1000/800 mg/m2) on days 1, 8 and 15, followed by mFOLFOX (oxaliplatin [85/75/65 mg/m2], 5-FU bolus [400/300/200 mg/m2], 5-FU infusion [2400/2000/1600 mg/m2]) on day 28, of a 42-day cycle. Patients were enrolled at the highest dose level with a subsequent 3 + 3 dose de-escalation plan. RESULTS Eleven patients (median age = 61, 64% with performance status [PS] = 1) were eligible. All patients received the highest dose level. No de-escalation was needed. A dose-limiting toxicity was reported, an upper gastrointestinal haemorrhage. The MTD was nab-paclitaxel 125 mg/m2, GEM 1000 mg/m2, oxaliplatin 85 mg/m2, 5-FU bolus 400 mg/m2 and 5-FU infusion 2400 mg/m2. Common all-grade toxicities were neutropenia (73%), anaemia (55%), thrombocytopenia (55%) and asthenia (55%). Other relevant toxicities were paraesthesia (46%), nausea (36%), dysesthesia (27%) and pyrexia (27%). Objective response rate was 50% and disease control rate was 80%. CONCLUSIONS The regimen of nab-paclitaxel plus GEM followed by mFOLFOX showed favourable safety and tolerability profiles with significant anti-tumor activity. More data are being achieved in a randomised phase II trial, to confirm efficacy rates and dismiss long-term neurotoxicity concerns regarding the sequencing of nab-paclitaxel and oxaliplatin.

Abstract
Resistance to chemotherapy often results from dysfunctional apoptosis, however multiple proteins with overlapping functions regulate this pathway. We sought to determine whether an extensively validated, deterministic apoptosis systems model, 'DR_MOMP', could be used as a stratification tool for the apoptosis sensitiser and BCL-2 antagonist, ABT-199 in patient-derived xenograft (PDX) models of colorectal cancer (CRC). Through quantitative profiling of BCL-2 family proteins, we identified two PDX models which were predicted by DR_MOMP to be sufficiently sensitive to 5-fluorouracil (5-FU)-based chemotherapy (CRC0344), or less responsive to chemotherapy but sensitised by ABT-199 (CRC0076). Treatment with ABT-199 significantly improved responses of CRC0076 PDXs to 5-FU-based chemotherapy, but showed no sensitisation in CRC0344 PDXs, as predicted from systems modelling. 18F-Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) scans were performed to investigate possible early biomarkers of response. In CRC0076, a significant post-treatment decrease in mean standard uptake value was indeed evident only in the combination treatment group. Radiomic CT feature analysis of pre-treatment images in CRC0076 and CRC0344 PDXs identified features which could phenotypically discriminate between models, but were not predictive of treatment responses. Collectively our data indicate that systems modelling may identify metastatic (m)CRC patients benefitting from ABT-199, and that 18F-FDG-PET could independently support such predictions.

Oxaliplatin retreatment in metastatic colorectal cancer: Systematic review and future research opportunities. Cancer Treat Rev 2020; 91:102112.

Abstract
BACKGROUND Oxaliplatin represents a main component of cytotoxic treatment regimens in colorectal cancer (CRC). Given its efficacy, oxaliplatin is frequently re-administered in the context of the continuum of care in metastatic CRC (mCRC). However, efficacy and tolerability of this therapeutic strategy has not been comprehensively assessed. METHODS We performed a systematic review of the literature on September 19th 2020, according to PRISMA criteria 2009. The research was performed on PubMed, ASCO Meeting Library, ESMO library and ClinicalTrials.gov for citations or ongoing trials. RESULTS 64 records were retrieved and 13 included in the systematic review: 8 full-text articles, 4 abstracts and 1 ongoing clinical trial. According to readministration timing, studies were classified as rechallenge/reintroduction (n = 8) or stop & go/intermittent therapeutic strategies (n = 4). The studies presented wide heterogeneity in terms of efficacy (Response Rate 6-31%; Disease Control Rate 39-79%; median Progression-Free Survival 3.1-7 months). Those patients who received retreatment after prior adjuvant oxaliplatin or exploiting a stop-&-go strategy appeared to achieve better outcomes. However, no formal comparisons on treatment outcomes were feasible. The most frequent grade 3 or higher adverse events were hematologic toxicities (5-27%), peripheral neuropathy (5-14%) and hypersensitivity reactions (5-20%). CONCLUSIONS Retreatment with oxaliplatin for mCRC is practiced based on scarce and heterogeneous data indicating efficacy and manageable toxicity. The best strategy to exploit this approach remains to be defined, and the most promising research avenue to improve therapeutic index of oxaliplatin is represented by selection of responder patients whose tumors harbor molecular defects in the DNA damage repair pathway.

Abstract
Peritoneal metastases from colorectal cancer are lethal. Cytoreductive surgery plus perioperative chemotherapy is a treatment option. A perioperative FOLFOX regimen with intraperitoneal oxaliplatin was described. The pharmacokinetic studies suggested efficacy.
Introduction Colorectal cancer can disseminate malignant cells to the peritoneal surfaces which over time progress to peritoneal metastases. Management of this type of metastatic disease has been approached using a combined treatment that consists of cytoreductive surgery and perioperative chemotherapy. To optimize these treatments a more effective chemotherapy that is used as planned part of the surgical procedure is required. Presentation of cases Pharmacologic studies to initiate a new perioperative chemotherapy treatment were modeled after the successful systemic treatments of metastatic colorectal cancer referred to as FOLFOX. A management plan that included all of the essential features of successful systemic chemotherapy was formulated. Pharmacokinetic studies of 5-fluorouracil given both intravenously and intraperitoneally and oxaliplatin given intraperitoneally were investigated. Discussion The compatibility of 5-fluorouracil and oxaliplatin was documented showing no degradation of either drug when they were mixed in-vitro over 24 h. The pharmacokinetic analysis of hyperthermic intraperitoneal chemotherapy (HIPEC) with oxaliplatin showed cytotoxic concentrations for 120 min. In order to maximize oxaliplatin’s effect, both intravenous bolus and continuous infusion 5-fluorouracil was combined with early postoperative intraperitoneal chemotherapy (EPIC). In total, 200 mg/m2 of oxaliplatin was combined with a minimum of 1600 mg of 5-fluorouracil over the 24 -h treatment plan. Conclusion This perioperative FOLFOX treatment was completed in 2 patients and the clinical effectiveness as a result of this in-depth case reports was presented. Formal phase II studies, as a result of these pharmacokinetic and clinical investigations, have been initiated.

ERCC overexpression associated with a poor response of cT4b colorectal cancer with FOLFOX-based neoadjuvant concurrent chemoradiation. Oncol Lett 2020; 20:212. [PMID: 32963618 PMCID: PMC7491057 DOI: 10.3892/ol.2020.12075] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2020] [Accepted: 07/22/2020] [Indexed: 12/14/2022] Open
Abstract
Colorectal cancer (CRC) of the clinical tumor stage T4b (cT4b) refers to advanced tumors with direct invasion of adjacent structures and the tumors are considered unresectable. Despite advancements in aggressive surgery and combination chemotherapy, the prognosis of cT4b CRC remains poor. Optimizing the therapeutic sequence administered to patients with cT4b CRC to improve clinical outcomes is crucial. In the present study, patients with unresectable cT4b and nodal stage N1-2 CRC were investigated at a single institution. A total of 20 consecutive patients were treated with pre-operative concurrent chemoradiation by using 5-fluorouracil/leucovorin/oxaliplatin (FOLFOX) since February 2015 and were regularly followed up until March 2020. Due to their poor response to concurrent chemoradiation (CCRT) with FOLFOX, the chemotherapy regimen was changed to irinotecan plus 5-fluorouracil/leucovorin (FOLFIRI) as the second-line neoadjuvant treatment. Genetic alterations, such as microsatellite instability (MSI), were documented, and the expression levels of excision repair cross-complementing group 1 (ERCC1) and ERCC2 were examined. Of the 20 patients, the tumors of 14 patients (70%) became resectable after FOLFIRI administration. The median duration between the last date of radiotherapy and surgery was 32.7 weeks (range, 10.1–59.3 weeks). Of note, 4 of the 14 patients with resectable tumors (28.6%) achieved a pathologic complete response. The median overall survival and progression-free survival were 27.5 months (range, 12–39 months) and 27.5 months (range, 8–39 months), respectively. The cancerous specimens of all of the patients (100%) exhibited ERCC2 overexpression and 18 specimens (90%) had ERCC1 overexpression. Only one tumor (5%) exhibited high MSI. The present study indicated that ERCC overexpression associated with the poor response of FOLFOX-based CCRT and FOLFIRI after FOLFOX-based CCRT failure may have a potential role in conversion to resectable tumors by neoadjuvant treatment in cT4b CRC. However, a further prospective study with more patients is required to improve the precision of the conclusions.

Fluorouracil Supplemented With Oxaliplatin or Irinotecan for Solid Tumors: Indications From Clinical Characteristics and Health Outcomes of Patients. Front Oncol 2020; 10:1542. [PMID: 32984012 PMCID: PMC7492525 DOI: 10.3389/fonc.2020.01542] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2020] [Accepted: 07/20/2020] [Indexed: 12/12/2022] Open
Abstract
Fluorouracil combined with oxaliplatin (FOLFOX) and fluorouracil combined with irinotecan (FOLFIRI) are both first-line clinical chemotherapy regimens. However, clinicians' selection of FOLFIRI or FOLFOX medication regimens and their effects on patients' health outcomes are not clear. The aim of this study was to evaluate the impacts on patient characteristics of FOLFIRI or FOLFOX medication regimen selection and the effects of each regimen on patients' health outcomes in a real-world setting. Three thousand seven hundred and twenty-five patients were retrieved and 610 of them were eventually included in this study based on the inclusion and exclusion criteria. The percentages of the TNM stage, cetuximab, bevacizumab, and tumor metastases between the FOLFIRI and FOLFOX groups were different (P < 0.001). In the multivariate Cox proportional hazards model, a significantly higher non-convalescent incidence of the FOLFOX group was found as compared with the FOLFIRI group (HR = 2.211, 95% CI = 1.257–3.888, P = 0.006). In conclusion, the TNM stage, whether combined with cetuximab or bevacizumab, and whether there was tumor metastasis presented as the key factors affecting medication selection between the FOLFIRI and FOLFOX regimens. The FOLFIRI regimen exhibited better effects on patients' long-term health outcomes than did the FOLFOX regimen. This study was registered on the World Health Organization International Clinical Trials Registry Platform (ChiCTR2000029201). Trial registration: ChiCTR2000029201.
