540 Background: Metastatic colon cancer (mCC) patients may receive multiple lines of treatment (Tx1, Tx2, etc.) consisting of one or more cytotoxic (CYT: 5FU/LV, oxaliplatin [OX], irinotecan [IRI]) and biologic (BIO: bevacizumab [BEV], cetuximab [CET], panitumumab [PAN]) drugs. The National Comprehensive Cancer Network (NCCN) provides evidence-based Tx recommendations for each line. The objective of this study was to examine real-world clinical practice patterns between 2002 and 2010. In particular, we compared the most common regimens across Tx lines and how Tx patterns changed over time. We also documented the uptake and use of new BIOs. Methods: We used population-based SEER-Medicare data to determine Tx1, Tx2, and Tx3 regimens of 4,616 mCC patients (the median age at diagnosis was 78) diagnosed in 2003-2009 and followed through 2010. We will use an algorithm previously developed by us to identify regimens. Results: The most common CYT backbone in Tx1 was OX (51% of patients) followed by 5FU/LV (30%). In comparison, IRI was a preferred choice in Tx2 (65%) and Tx3 (31%). In 2003, the most common Tx1 regimens were 5FU/LV- (56%) and IRI-based (35%). 5FU/LV and IRI use decreased to 22% and 9% respectively in 2009, while OX use increased from 7% in 2003 to 63% in 2009. In 2004, the FDA approved BEV for Tx1. BEV’s share increased from 9% in 2004 to 53% in 2005. BEV was used in 9% of Tx2 regimens in 2004 and 46% in 2005. CET was approved in 2004. CET was used in less than 5% of Tx1 regimens in any year up to 2010. CET use in Tx2 increased from 19% to 27% between 2005 and 2007, and declined to 23% in 2010. The FDA approved PAN in September 2006 for treatment after failure of CYT-based regimens, i.e., primarily in Tx3 and beyond. Only 350 (8%) of patients received Tx3, and of these 59 (17%) received PAN without a CYT backbone. One in three Tx3 regimens consisted of biologics only (54% CET, 43% PAN). Conclusions: This study used SEER-Medicare registry data to examine and document real-world clinical practice patterns in treatment of elderly mCC patients between 2003 and 2010. We observed that as new biologic agents were introduced to the market, variations in the combinations and the number of treatment have significantly and rapidly changed.

Camellia Nitidissima

Camellia nitidissima Chi (CNC) is a traditional Chinese medicine (TCM) with anticancer property. However, its underlying mechanisms of anti-colon cancer (CC) remain unknown. Therefore, a systematic approach is proposed in the present study to elucidate the anticancer mechanisms of CNC based on network pharmacology and experimental validation. Initially, the potential active ingredients of CNC were verified via the TCMSP database based on the oral bioavailability (OB) and drug-likeness (DL) terms. Hub targets of CNC were acquired from SwissTarget prediction and TCMSP databases, and target genes related to CC were gathered from GeneCards and OMIM databases. Cytoscape was used to establish the compound-target networks. Next, the hub target genes collected from the CNC and CC were parsed via GO and KEGG analysis. Results of GO and KEGG analysis reveal that quercetin and luteolin in CNC, VEGFA and AKT1 targets, and PI3K-Akt pathway were associated with the suppression of CC. Besides, the result of molecular docking unveils that VEGFA demonstrates the most powerful binding affinity among the binding outcomes. This finding was successfully validated using in vitro HCT116 cell model experiment. In conclusion, this study proved the usefulness of integrating network pharmacology with in vitro experiments in the elucidation of underlying molecular mechanisms of TCM.

Colorectal cancer (CRC) is the third most common type of cancer worldwide and a leading cause of cancer death. According to the Malaysian National Cancer Registry Report 2012–2016, colorectal cancer was the second most common cancer in Malaysia after breast cancer. Recent treatments for colon cancer cases have caused side effects and recurrence in patients. One of the alternative ways to fight cancer is by using natural products. Curcumin is a compound of the rhizomes of Curcuma longa that possesses a broad range of pharmacological activities. Curcumin has been studied for decades but due to its low bioavailability, its usage as a therapeutic agent has been compromised. This has led to the development of a chemically synthesized curcuminoid analogue, (2E,6E)-2,6-bis(2,3-dimethoxybenzylidine) cyclohexanone (DMCH), to overcome the drawbacks. This study aims to examine the potential of DMCH for cytotoxicity, apoptosis induction, and activation of apoptosis-related proteins on the colon cancer cell lines HT29 and SW620. The cytotoxic activity of DMCH was evaluated using the [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] (MTT) cell viability assay on both of the cell lines, HT29 and SW620. To determine the mode of cell death, an acridine orange/propidium iodide (AO/PI) assay was conducted, followed by Annexin V/FITC, cell cycle analysis, and JC-1 assay using a flow cytometer. A proteome profiler angiogenesis assay was conducted to determine the protein expression. The inhibitory concentration (IC50) of DMCH in SW620 and HT29 was 7.50 ± 1.19 and 9.80 ± 0.55 µg/mL, respectively. The treated cells displayed morphological features characteristic of apoptosis. The flow cytometry analysis confirmed that DMCH induced apoptosis as shown by an increase in the sub-G0/G1 population and an increase in the early apoptosis and late apoptosis populations compared with untreated cells. A higher number of apoptotic cells were observed on treated SW620 cells as compared to HT29 cells. Human apoptosis proteome profiler analysis revealed upregulation of Bax and Bad proteins and downregulation of Livin proteins in both the HT29 and SW620 cell lines. Collectively, DMCH induced cell death via apoptosis, and the effect was more pronounced on SW620 metastatic colon cancer cells, suggesting its potential effects as an antimetastatic agent targeting colon cancer cells.

Treatment of metastatic colon cancer has evolved over time. More evidence has been emerging in recent years supporting metastasectomy in selected patients. We sought to elucidate whether the type of institution—community, comprehensive community, academic/research, and integrated cancer network—would have an effect on patient outcome, specifically those colon cancer patients with isolated liver metastasis. This retrospective cohort study queried the National Cancer Database (NCDB) from 2010 to 2014 for patients who were 18 years of age or older with stage IVA colon cancer with isolated liver metastasis. We then performed uni- and multivariate analyses comparing patients based on such factors as age, tumor characteristics, primary tumor location, rate of chemotherapy, and type of treating institution. Patients who came from regions of higher income, receiving chemotherapy, and presenting to an academic/research hospital were more likely to undergo metastasectomy. Median survival was longest at academic/community hospitals at 22.4 months, 6 to 7 months longer than the other three types of institutions. Factors positively affecting survival included receiving chemotherapy, presenting to an academic/research institution, and undergoing metastasectomy, all at P < .05. In our study, the rate of metastasectomy was more than double at academic/research institutions for those with stage IVA colon cancer with isolated liver metastasis. Prior studies have quoted a mere 4.1% synchronous colon resection and metastasectomy. Our findings suggest that we should maintain multidisciplinary approach to this complex disease process and that perhaps it is time for us to consider regionalization of care in treating metastatic colon cancer.
