The Influence of Adjuvant Chemotherapy Dose Intensity on Five-Year Outcomes in Resected Colon Cancer: A Single Centre Retrospective Analysis. Curr Oncol 2021; 28:4031-4041. [PMID: 34677260 PMCID: PMC8535138 DOI: 10.3390/curroncol28050342] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 08/04/2021] [Accepted: 09/28/2021] [Indexed: 01/22/2023] Open
Abstract
There is evidence that achieving a dose intensity > 80% in adjuvant colon cancer treatment improves survival. In total, 192 consecutive patients with resected stage III and high-risk stage II colon cancer that received adjuvant chemotherapy were retrospectively analyzed. Patients who received at least 6 weeks of adjuvant therapy were included. The primary objective was to assess the influence of dose index (DI) and relative dose intensity (RDI) on DFS and OS at 3 and 5 years in patients receiving fluorouracil-based doublet therapy with oxaliplatin (FOLFOX) (5-FU and oxaliplatin assessed separately), or capecitabine monotherapy. In the capecitabine group, DFS rates for 3 and 5 years were 66.7% and 57.6%, respectively, while OS rates were 80.3% and 66.7%, respectively. Those who received FOLFOX had DFS rates of 76.9% and 71.2% at 3 and 5 years, respectively. OS rates were 86.4% and 76.7% at 3 and 5 years, respectively. Median RDI was 73.8% for capecitabine and 76.3% and 85.6% for the oxaliplatin and 5-FU components respectively. Based on a multivariate analysis in patients receiving FOLFOX, those with an oxaliplatin DI > 80% had improvements in DFS and OS compared to those with an oxaliplatin DI of ≤80%. Otherwise, there was no significant difference in DFS or OS when comparing patients who achieved an RDI or a DI of above versus below 80% in the patients receiving adjuvant chemotherapy for resected colon cancer.

Selection of Oral Therapeutics in China for the Treatment of Colorectal Cancer. Curr Treat Options Oncol 2021; 22:55.

Abstract
OPINION STATEMENT Intravenous administration of fluoropyrimidine-based chemotherapy has been the backbone of treatment in colorectal cancer (CRC) for decades. The availability of oral capecitabine has improved the tolerability and simplified combination schedules. In addition to capecitabine, several other oral drugs have proven efficacy, particularly in palliative treatment lines. Clinical guidelines describe several available third-line treatment options for metastatic CRC (mCRC), but few insights are provided to guide the selection and sequence. In this review, we describe the available evidence and most recent data concerning oral drugs with proven efficacy in CRC, including antiangiogenetic tyrosine kinase inhibitors (VEGFR TKIs), inhibitors blocking EGFR/Raf/MEK/ERK signaling pathway and modified fluoropyrimidine, and share recommendations and insights on selecting third-line oral therapies for mCRC in China. In general, third-line treatment options for mCRC are mainly regorafenib, fruquintinib, and chemo/targeted therapy reintroduction, while FTD/TPI was rarely used in China probably due to poor accessibility. Fruquintinib is preferred in patients with poor performance status (PS), elder age, and severe organ dysfunction, compared to regorafenib. New drugs of clinical trials were more recommended for the patients with BRAF mutant tumor, and those with good previous treatment efficacy tended to be recommended for chemo/targeted therapy reintroduction. The management of mCRC is evolving, and it must be emphasized that the consideration and recommendations presented here reflect current treatment practices in China and thus might change according to new clinical data as well as the availability of new oral drugs.

J Cancer 2019; 10:3717-3727. [PMID: 31333789 PMCID: PMC6636299 DOI: 10.7150/jca.32205] [Citation(s) in RCA: 40] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2018] [Accepted: 05/15/2019] [Indexed: 12/20/2022] Open
Abstract
Introduction: With a gap in a full understanding of the mechanisms by which survival is extended for patients with cancer who are treated with novel biologic and targeted agents, there is the risk that discordant progression-free and overall survival outcomes are observed due to poor clinical trial design or biases in the interpretation of data. This study was designed to examine the role of study quality and design on the outcomes observed with biologic and targeted agents. Methods: A review of studies in clinicaltrials.gov supplemented with a literature review in OVID Medline was conducted to identify all randomized trials of a biologic/targeted agent versus a non-biologic/targeted comparator in oncology that report both median overall and progression-free survival outcomes. Details of the study, design, population, drugs, and outcomes were extracted. Study quality was evaluated using the PEDro scale. Data were summarized using SPSS 22.0.0.0. Results: A total of 192 unique studies of 206 pairwise comparisons between a biologic/targeted and comparator were identified. The average absolute magnitude of post-progression survival (difference between OS and PFS) was 9.7 months for biologic/targeted therapy and 9.8 for the comparator. A total of 64 comparisons (31.1%) showed an increase in OS and decrease in PFS, or vice versa, and 25 (12.1%) showed a magnitude of more than 4 months difference between the delta of OS and delta of PFS between the biologic/targeted and comparator arms. Average study quality was high overall (7.7/10), and was comparable for studies with directional differences (7.2/10) as well as for those with the greatest magnitude in post-progression survival (7.4/10). Conclusion: This review and analysis specifically examined small PFS benefit with large OS benefit as well as small OS benefit with large PFS benefit, including differences in direction of PFS and OS outcomes. No evidence was identified that these are the result of poor study design, but may rather be due to the mechanism of action, specific disease, and population under study. Further work is needed to understand the mechanism of action of novel biologic/targeted agents to better understand their interaction with the tumor microenvironment.

Abstract
OBJECTIVES Palliative chemotherapy's role is to prolong survival while minimizing treatment toxicities to preserve or improve quality of life. We have recently published a phase II trial of dose reduced capecitabine in older or frail patients with advanced colorectal cancer (aCRC). We herein provide a robust analysis of the health related quality of life (HRQoL) data from our trial. METHODS A single arm multi-centered phase II trial of dose reduced capecitabine (1500 or 2000 mg/m2 days one-fourteen q21 days) in older or frail patients. Participants (182 patients) were asked to complete Functional Assessment of Cancer Therapy general questionnaire (FACT-G) at enrollment, after each cycle of capecitabine, and once upon completion, if possible. RESULTS 157 patients completed a baseline questionnaire (86%), and 137 patients (75%) completed at least one subsequent questionnaire. The mean baseline score was 81.6, out of a possible 108. The mean score peaked at 92 after cycle 10. The mean change from baseline was always positive. Patients achieving the minimal clinically important difference (MCID) ranged from 30% to 45% during treatment. Higher baseline FACT-G and Physical Well-being score were independently prognostic for improved survival (p = 0.006 and p < 0.0001, respectively). Time until definitive deterioration (TUDD) was insignificantly longer in patients with a higher baseline FACT-G (p = 0.18). CONCLUSION Baseline HRQoL scores were independently prognostic for survival, supporting their importance. Compared to full dose, reduced dose capecitabine has previously demonstrated equivalent efficacy and reduced toxicity. We have reported dose reduced capecitabine improves quality of life in older or frail patients with aCRC, further supporting its use in the management of aCRC.

Abstract
BACKGROUND Combination chemotherapy is associated with improved outcomes in trials of selected fit patients with advanced colorectal cancer (acrc). For older or less-fit patients, combination chemotherapy is associated with greater toxicity and less benefit. Capecitabine monotherapy is a reasonable option for those patients, but the optimal dose remains controversial. METHODS A multicentre phase i/ii trial of reduced-dose capecitabine (2000 mg/m2, days 1-14 every 21 days) was conducted in 221 patients representing one or more of the following subsets: age greater than 65 years (n = 167), Eastern Cooperative Oncology Group (ecog) performance status of 1 or greater (n = 139), elevated lactate dehydrogenase (ldh) (n = 105), or prior pelvic radiation (n = 54). Based on phase i results, patients with prior pelvic radiation received capecitabine 750 mg/m2 twice daily. The goal was to ascertain efficacy in a design that was unlikely to cause high levels of toxicity. RESULTS Median age in the patient cohort was 72 years. A median of 5 and a mean of 8 capecitabine cycles were given (range: 0-50 cycles). Grade 3 or 4 toxicity occurred in 25% of patients during the first 3 cycles (8.1% hand-foot syndrome, 7.7% diarrhea). The response rate was 13.6%, with a 69.7% disease control rate. Median progression-free survival (pfs) was 5.6 months. Post progression, 56 patients received further capecitabine monotherapy (median of 4 additional cycles). Median overall survival duration for the patients was 14.3 months. Median survival was significantly higher for those who, at baseline, had an ecog performance status of 0 (compared with 1 or more) and normal ldh (compared with elevated ldh). CONCLUSIONS Toxicity is less with dose-reduced capecitabine than with historical full-dose capecitabine, with only a small trade-off in efficacy, seen as a lower objective response rate. The improved tolerability could lead to an increased number of cycles of therapy, and pfs appears to be consistently higher at the lower dose. Those observations should, in the absence of a head-to-head clinical trial, be viewed as compelling evidence that 1000 mg/m2, or even 750 mg/m2, twice daily is an appropriate dose in elderly or frail patients with acrc.

Current Status and Perspectives Regarding LNA-Anti-miR Oligonucleotides and microRNA miR-21 Inhibitors as a Potential Therapeutic Option in Treatment of Colorectal Cancer. J Cell Biochem 2017; 118:4129-4140.

Abstract
Colorectal cancer (CRC) is among the leading causes of cancer-related death, principally due to its metastatic spread and multifactorial chemoresistance. The therapeutic failure can also be explained by inter- or intra-tumor genetic heterogeneity and tumor stromal content. Thus, the identification of novel prognostic biomarkers and therapeutic options are warranted in the management of CRC patients. There are data showing that microRNA-21 is elevated in different types of cancer, particularly colon adenocarcinoma and that this is association with a poor prognosis. This suggests that microRNA-21 may be of value as a potential therapeutic target. Furthermore, locked nucleic acid (LNA)-modified oligonucleotides have recently emerged as a therapeutic option for targeting dysregulated miRNAs in cancer therapy, through antisense-based gene silencing. Further work is required to identify innovative anticancer drugs that improve the current therapy either through novel combinatorial approaches or with better efficacy than conventional drugs. We aimed to provide an overview of the preclinical and clinical studies targeting key dysregulated signaling pathways in CRC as well as the therapeutic application of LNA-modified oligonucleotides, and miR inhibitors in the treatment of CRC patients.
