Purpose: Capecitabine and oxaliplatin, two new agents with potential synergistic activity, have demonstrated promising antitumor efficacy in advanced colorectal cancer (ACC). Preclinical and clinical evidence indicating that dose intensification of the oral fluorouracil prodrug might result in improved therapeutic results led us to the present randomized multicenter phase II study. Patients and Methods: Eighty-nine patients with bidimensionally measurable ACC previously untreated for metastatic disease were randomly allocated to receive oxaliplatin 130 mg/m2 day 1 plus capecitabine 2,000 mg/m2/d days 1 to 14 every 3 weeks (arm A) or to receive oxaliplatin 85 mg/m2 days 1 and 14 combined with capecitabine 3,500 mg/m2 days 1 to 7 and 14 to 21 every 4 weeks (arm B). In both treatment arms, chemotherapy was continued for a total of 6 months unless there was prior evidence of progression of disease. Results: Patients allocated to the high-dose capecitabine combination arm B had a higher radiologically confirmed response rate (54.5% v 42.2%) and a significantly longer median progression-free survival time than those allocated to control arm A (10.5 v 6.0 months; P = .0013). Median overall survival times cannot be calculated for either treatment arm at this point. Despite a 34% higher dose intensity of capecitabine in arm B, there was no difference in hematologic toxicity between treatment arms (neutropenia/thrombocytopenia: 60%/43% in arm B v 56%/33% in arm A). Similarly, the incidence rate and degree of nonhematologic adverse events were comparable: The most commonly encountered symptoms (all grades, arm A and arm B) included nausea/emesis (A: 58%; B: 62%), diarrhea (A: 44%; B: 31%), peripheral sensory neuropathy (A: 80%; B: 83%), and fatigue (A: 40%; B: 50%). Conclusion: Results of this study indicate that both combination regimens are feasible, tolerable, and clinically active. The dose-intensified bimonthly capecitabine arm, however, seems to be more effective in increasing both response rate and progression-free survival time.

602 Background: The Kyushu Study group of Clinical Cancer conducted a phase II study that evaluated the FIREFOX regimen. (KSCC0701, Akagi et al, J Clin Oncol 28:15s, 2010). This study demonstrated the efficacy and mild neurotoxicity of this regimen. The present study evaluated the efficacy and safety of the FIREFOX plus bevacizumab (bev). Methods: Eligibility criteria included histologically confirmed advanced colorectal cancer, ECOG PS 0-2 and adequate bone marrow, renal and hepatic function. Patients (pts) received an alternating regimen of 4 cycles of mFOLFOX-6 plus bev (oxaliplatin 85 mg/m2, leucovorin 200 mg/m2, bev 5 mg/kg d1 followed by 400 mg/m2 bolus 5-FU and a 46-hr 2,400 mg/m2 5-FU infusion every 2 weeks) followed by 4 cycles of FOLFIRI plus bev (oxaliplatin replaced with irinotecan 150 mg/m2 d1). This schedule was repeated until unacceptable toxicity or disease progression occurred. The primary endpoint is progression-free survival. (UMIN000001312) Results: Of the 52 pts enrolled from May 2008 to July 2009. Two of the patients did not fulfill the eligibility criteria. M/F, 30/20; median age, 59.5 years (range 37 - 75); ECOG PS 0/1/2, 46/4/0. The median number of administration cycles was 14 (range, 2 - 44). Response rate (RECIST criteria) for CR, PR, SD, PD and NE were 2 (4%), 28 (56%), 14 (28%), 4 (8%) and 2 (4%), respectively. An overall response rate was 60% (95% CI: 45 - 74%). Median progression-free survival was14.2 M (95% CI: 10.6 M-16.3 M) and median overall survival was 27.5 M (95% CI; 22.4 M – not determined). The 2-year survival rate was 56.8%. Of the 52 pts evaluated for toxicity. The most common grade 3-4 adverse events were leukopenia (7.7%), neutropenia (32.7%), anemia (1.9%), fatigue (9.6%), anorexia (13.5%), stomatitis (3.8%), neurotoxicity (3.8%), hypertension (1.9%), diarrhea (7.7%), febrile neutropenia (3.8%), nausea (9.6%), vomiting (5.8%), hypersensitivity (3.8%), and thromboembolism (1.9%). Conclusions: The results of this phase II study show that the FIREFOX plus bev regimen is effective and well tolerated in the first-line treatment of advanced colorectal cancer. The low rate of neurotoxicity is also promising.

e15061 Background: There are limited therapeutic options for the treatment of advanced colorectal cancer which fail first-line chemotherapy. Phase I studies have shown that the combined application of the irinotecan (CPT-11) and raltitrexed has significant synergistic effect and acceptable toxicity. The aim of this multicenter study was to assess the efficacy and toxicity of second-line raltitrexed plus irinotecan in Chinese patients with advanced colorectal cancer. Methods: This is an open-label,single-arm, multicenter, phase II trial (Registered in clinicaltrials.gov with NCT03053167).Brief inclusion criteria: patients were aged 18 to 75 years with locally advanced or metastatic colorectal cancer after failure of oxaliplatin and fluorouracil therapy. Enrolled patients received CPT-11 (180 mg /m2 , d1) and raltitrexed (3 mg/m2, d1) each 21-day cycle until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival (PFS), and the secondary endpoints were disease control rate (DCR), objective response rate (ORR), overall survival (OS), quality of life (QOL) and safety. In all, 100 patients were required for primary point testing. Results: Between November 2016 and December 2018, a total of 70 patients were screened for enrollment and 53 patients reached the primary endpoint. Nine patients achieved a partial response and twenty-seven stable disease. The overall response rate was 17% (9/53) and the disease control rate was 67.9% (36/53). Median progression-free survival (mPFS) was 4.3 months and median overall survival was not observed. The most common adverse events were elevated transaminases (21/53), fatigue (14/53), diarrhea (12/53), neutrocytopenia (10/53), erythrocytopenia (9/53), hypohemoglobin (8/53) and leukocytopenia (6/53). The total incidence of grade 3/4 toxicity was 17% (9/53) , mainly diarrhea (2/53), neutrocytopenia (2/53) and elevated transaminases (2/53). There were no treatment-related deaths. Conclusions: We have demonstrated that CPT-11 plus raltitrexed is active and feasible in patients with second-line treatment in advanced colorectal cancer. This trial will progress as planned. Clinical trial information: NCT03053167.

Background. The most effective treatment of immune checkpoint inhibitors (ICIs) is restricted in microsatellite instability (MSI-H) subsets of advanced colorectal cancer, but MSI-H only accounts for 4-5% among them. ICIs are completely ineffective in advanced colorectal cancer patients with microsatellite stable (MSS), according to literatures published. Regorafenib is a novel tyrosine kinase inhibitor (TKIs) that could normalize tumor blood vessels by inhibiting vascular endothelial growth factor receptor and its downstream, thus improving cytotoxic T cell infiltration in tumor microenvironment, which has a synergistic effect with ICIs. Toripalimab is a type of anti-PD-1 monoclonal antibody produced by Junshi Biosciences in China. Herein, we aimed to explore the efficacy and safety of regorafenib combined with toripalimab in the third-line and beyond treatment of advanced colorectal cancer. Methods. We evaluated the outcomes of MSS patients with advanced colorectal cancer who received regorafenib combined with toripalimab in the Second Affiliated Hospital of Nanchang University from June 2019 to January 2021. These patients had previously received at least second-line treatment; the regimens were oxaliplatin and irinotecan-based chemotherapy and/or accompanied with bevacizumab or cetuximab. Thirty-three patients were treated orally with regorafenib 80 mg or 120 mg once daily for 21 days, 28 days as a cycle, combined with intravenous toripalimab until disease progression or intolerant to adverse reactions. We used the Kaplan–Meier method to estimate the rate of progression-free survival (PFS) and log-rank method to do a statistical test of the survival curve. The Cox regression model was used to analyze the influence of multiple factors on PFS. The primary endpoints were objective remission rate (ORR) and disease control rate (DCR). The secondary endpoints were the incidence of adverse reactions and median progression-free survival (mPFS). Results. The evaluation of treatment effects was assessed according to RECIST 1.1. Four patients (12.12%) got partial response, twelve patients (36.36%) experienced stable disease, and seventeen patients (51.52%) suffered progressive disease. ORR was 12.12% and DCR was 48.48%. mPFS was 113 days (95% CI: 0–272.1). In univariate analysis, patients who had previously received second-line treatment were significantly better than those who had received third-line or more treatment ( p = 0.005 ). Lung metastasis was a negative factor in combined therapy ( p = 0.032 ). Five patients without previous treatment of bevacizumab were effective. Previous treatment without bevacizumab showed a trend of effective when combination therapy ( p = 0.034 ). It was also a positive factor that the Eastern Cooperative Oncology Group performance status (ECOG) score was 0 ( p = 0.034 ). Multivariable Cox regression analysis showed the number of previous chemotherapy lines and excision of primary lesions were independent prognostic factors. The most common treatment-related adverse reactions were hand-foot syndrome (33.33%), liver dysfunction (27.27), hypothyroidism (24.24%), fever (24.24%), fatigue (21.21%), leukopenia (15.15%), hypertension (12.12%), platelet count decreased (6.06%), diarrhea (3.03%), and myocarditis (3.03%); one patient stopped treatment as myocarditis. The incidence of grade 3/4 adverse reactions was 9.09%. Conclusions. Regorafenib combined with toripalimab has a promising effect in the third-line and beyond treatment of advanced colorectal cancer. In the early use of combination therapy, excision of primary lesions can have a positive impact in regorafenib and toripalimab combination. This treatment-related adverse reactions are tolerant in combined therapy.

PURPOSE The advantage of chemotherapy in asymptomatic patients with advanced colorectal cancer is debatable. Whether early chemotherapy improves survival and the length of the symptom-free period versus no therapy until symptoms appear was studied in a randomized trial. PATIENTS AND METHODS A total of 183 patients with advanced, but asymptomatic colorectal cancer were randomly allocated to receive either initial treatment with sequential methotrexate 250 mg/m2 during the first 2 hours, and fluorouracil (5-FU) 500 mg/m2 at hours 3 and 23 followed by leucovorin rescue initiated at hour 24 (MFL) for 12 courses or to primary expectancy with chemotherapy not considered until symptoms appeared. One patient was ineligible and excluded from analysis. Nine patients did not fulfill the inclusion criteria and five patients refused treatment allocation; these patients were not excluded from the study population so as not to introduce bias. So far, 51 of 90 (60%) patients in the expectancy group have received chemotherapy. RESULTS Overall survival was better in the MFL group than in the expectancy group (Breslow-Gehan, P less than .02; log-rank, P = .13) with a difference in median survival of approximately 5 months. Also the symptom-free period and the time to disease progression were longer in the MFL group (P less than .001), with median differences of 8 and 4 months, respectively. Toxicity to MFL treatment was low; however, three patients died because of toxicity--none of them should have received therapy because of poor performance or S-creatinine elevation. The patients maintained an excellent performance throughout the MFL treatment unless the disease was progressive. CONCLUSION We concluded that early treatment with MFL in asymptomatic patients with advanced colorectal cancer prolongs survival, the asymptomatic period, and the time to disease progression by approximately 6 months over primary expectancy.

PURPOSE To assess the efficacy of irinotecan (CPT-11) in the treatment of advanced colorectal cancer in both chemotherapy-naive and pretreated patients. PATIENTS AND METHODS Two hundred thirteen patients (aged 18 to 75 years) with metastatic colorectal cancer, World Health Organization (WHO) performance status < or = 2, and life expectancy > or = 3 months were treated with CPT-11 350 mg/m2 every 3 weeks. All 178 patients eligible for efficacy analysis had not received more than one prior fluorouracil (5-FU)-based chemotherapy regimen (adjuvant or palliative) and had adequate hematologic, renal, and hepatic function. RESULTS Primary tumor sites were the colon (71%) and rectum (28%). Sixty-six percent of the patients had > or = two metastatic sites. Ninety-eight percent of the patients had undergone previous surgery, and 77.5% had received prior chemotherapy. Thirty-two of 178 eligible patients achieved on objective response (four complete responses [CRs] and 28 partial responses [PRs]; response rate, 18%; 95% confidence interval, 12.6% to 24.4%), 65 were stable, and 59 progressed. The response rate was 17.7% in the pretreated group and 18.8% in the chemotherapy-naive group. Within the former subgroup, response rates of 16.1% were reported in patients who were progressive on prior 5-FU chemotherapy and 19.1% in patients who were progressive off such treatment. The median duration of objective response (9.1 months) and median time to achievement of a response (9.3 weeks) did not differ between chemotherapy-naive and pretreated patients. The most frequent adverse events were neutropenia, which developed in 80% of the patients, delayed diarrhea (87%), alopecia (88%), fatigue (81%), and nausea/vomiting (77%). All these adverse events were manageable. Severe (WHO grade 3 or 4) neutropenia was only observed in 18% of the cycles, leukopenia in 11%, delayed diarrhea in 11%, and nausea and vomiting in 3%. Development of simultaneous grade 3 or 4 neutropenia and delayed diarrhea during 4% of the cycles was the safety issue of greatest concern. CONCLUSION CPT-11 has definite activity in the treatment of advanced metastatic colorectal cancer both in chemotherapy-naive and in pretreated patients who experienced disease progression on 5-FU, which suggests a lack of cross-resistance between CPT-11 and 5-FU. Diarrhea and neutropenia, the major toxicities of CPT-11, contribute to the risk to develop febrile neutropenic sepsis.
