Abstract
PURPOSE This study aimed to compare local regrowth rates after total neoadjuvant therapy (TNT) versus standard neoadjuvant chemoradiotherapy (SNCRT) in locally advanced rectal cancer (LARC) patients that were strictly selected and assessed with a multimodal approach. Secondary outcomes were 4-year disease-free (DFS) and overall survival (OS) rates. METHODS Locally advanced rectal cancer patients without distant metastases treated at Koç Healthcare Group between January 2014 and January 2021 were included. Patients were assessed for complete response with a combination of digital rectal exam, endoscopy, and magnetic resonance imaging with a dedicated rectum protocol. The systemic evaluation was performed with an upper abdomen MRI using intravenous hepatobiliary contrast agent and a thorax CT. RESULTS Of the 270 patients with LARC, 182 fulfilled the inclusion criteria. Ninety-seven (53.3%) underwent TNT, while 85 (46.7%) underwent SNCRT. A cumulative combination of pathological and sustained clinical complete response was significantly higher in the TNT group than in the SNCRT (45.4% vs. 20.0%, p < 0.0001). After a median follow-up of 48 months, seven patients in the W&W group had regrowth [TNT: 4 (10.8%) vs. SNCRT: 3 (23.1%), p = 0.357]. Based on pathological examination, complete/near complete mesorectum rates (p = 1.000) and circumferential resection margin positivity rates (p = 1.000) were similar between the groups. The 4-year DFS and OS rates were comparable. The patients with clinical or pathological complete response had significantly longer overall survival (p = 0.017) regardless of the type of neoadjuvant treatment. CONCLUSIONS Multimodal assessment after TNT effectively detects complete responders, resulting in low local recurrence and increased cumulative complete response rates. However, these outcomes did not translate into a survival advantage.

Radiosensitizing Effects of Irinotecan versus Oxaliplatin Alone and in Combination with 5-Fluorouracil on Human Colorectal Cancer Cells. Int J Mol Sci 2023; 24:10385. [PMID: 37373535 DOI: 10.3390/ijms241210385] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 06/15/2023] [Accepted: 06/16/2023] [Indexed: 06/29/2023] Open
Abstract
To date, oxaliplatin and irinotecan are used in combination with 5-flourouracil (5-FU) for metastatic colorectal cancer. In this study it was tested whether oxaliplatin and irinotecan and their combinations with 5-FU have an enhanced effect when treated simultaneously with ionizing radiation. In addition, it should be compared whether one combination therapy is more effective than the other. Colorectal cancer cells (HT-29) were treated with irinotecan or oxaliplatin, both alone and in combination with 5-FU, and subsequently irradiated. The cell growth, metabolic activity and proliferation of cells were investigated, and the clonogenic survival was determined. Furthermore, the assessment of radiation-induced DNA damage and the influence of the drugs and their combinations on DNA damage repair was investigated. Treatment with irinotecan or oxaliplatin in combination with 5-FU inhibited proliferation and metabolic activity as well as clonogenic survival and the DNA damage repair capacity of the tumor cells. The comparison of oxaliplatin and irinotecan with simultaneous irradiation showed the same effect of both drugs. When oxaliplatin or irinotecan was combined with 5-FU, tumor cell survival was significantly lower than with monotherapy; however, there was no superiority of either combination regimen. Our results have shown that the combination of 5-FU and irinotecan is as effective as the combination of 5-FU with oxaliplatin. Therefore, our data support the use of FOLFIRI as a radiosensitizer.

Risk of Thromboembolic Events and Major Adverse Cardiovascular Events Following Antivascular Endothelial Growth Factor Therapy in Patients with Colorectal Cancer. Cancers (Basel) 2022; 15:cancers15010009. [PMID: 36612005 PMCID: PMC9817700 DOI: 10.3390/cancers15010009] [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: 12/02/2022] [Revised: 12/16/2022] [Accepted: 12/16/2022] [Indexed: 12/24/2022] Open
Abstract
Antivascular endothelial growth factor (anti-VEGF) therapy has been a standard treatment for patients with metastatic colorectal cancer. However, the risk of thromboembolic events and cardiovascular events associated with this therapy remains controversial. We assessed whether anti-VEGF therapy increases the risk of thromboembolic events or major adverse cardiovascular events (MACEs) in patients with colorectal cancer based on real-world evidence. This retrospective cohort study was designed using linked 2009-2016 nationwide databases, including the Taiwan Cancer Registry, the National Health Insurance Research Database, and Taiwan's National Death Index. In total, 189,708 patients newly diagnosed as having advanced colorectal cancer from 2009 to 2016 were identified and categorized into the anti-VEGF and comparator groups through age, sex, clinical stage, and diagnosis date (within 180 days) matching. Propensity score matching was further performed to balance the baseline characteristics between the two groups. The Kaplan-Meier method was used to create the cumulative incidence curves of thromboembolic events and MACEs, and log-rank tests were used to compare the differences in Kaplan-Meier curves. Competing hazard ratios (HRs) for thromboembolic events and MACEs were estimated using the Fine-Gray method when considering the competing event of death. Statistical analysis was performed using two-tailed tests with a significance level of 0.05. In total, 4635 patients were included in both the anti-VEGF group and comparator group. The risk of thromboembolic events and MACEs did not differ significantly between the two groups. After propensity score matching, the adjusted HR for MACEs or thromboembolic events was 1.040, which for MACEs was 0.989, and that for thromboembolic events was 1.028. The competing HR for MACEs or thromboembolic events was 0.921, which for MACEs, was 0.862, and that for thromboembolic events was 0.908. In conclusion, patients with advanced colorectal cancer who received anti-VEGF therapy did not exhibit significantly higher risks of thromboembolic events and MACEs than those without anti-VEGF therapy. Our study provides real-world evidence regarding the safety of anti-VEGF therapy in Asian patients with advanced colorectal cancer.

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.

Characterization of Patients With and Without Painful Peripheral Neuropathy After Receiving Neurotoxic Chemotherapy: Traditional Quantitative Sensory Testing vs C-Fiber and Aδ-Fiber Selective Diode Laser Stimulation. THE JOURNAL OF PAIN 2022; 23:796-809. [PMID: 34896646 PMCID: PMC9086082 DOI: 10.1016/j.jpain.2021.11.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Revised: 11/09/2021] [Accepted: 11/12/2021] [Indexed: 11/21/2022]
Abstract
Painful chemotherapy induced peripheral neuropathy (CIPN) is a common complication of chemotherapy with drugs such as taxanes and platinum compounds. Currently, no methods are available for early detection of sensory changes that are associated with painful CIPN, nor are there biomarkers that are specific to painful CIPN. This study aimed to compare Diode Laser fiber type-selective stimulator (DLss), a method to selectively stimulate cutaneous C and Aδ fibers, to traditional quantitative sensory testing (QST) in determining psychophysical differences between patients with painful CIPN and a control group. Sensory testing was performed on the dorsal mid-foot of 20 patients with painful neuropathy after taxane- or platinum-based chemotherapy, and 20 patients who received similar neurotoxic chemotherapy, without painful CIPN. In a multivariable analysis, C-fiber to Aδ fiber detection threshold ratio, measured by DLss, was significantly different between the groups (P <.05). While QST parameters such as warmth detection threshold were different between the groups in univariate analyses, these findings were likely attributable to group differences in patient age and cumulative chemotherapy dose. PERSPECTIVE: In this study, fiber-specific DLss test showed potential in identifying sensory changes that are specific for painful neuropathy, encouraging future testing of this approach as a biomarker for early detection of painful CIPN. TRIAL REGISTRATION: The study was approved by the Washington University Institutional Review Board (#201807162) and registered at ClinicalTrials.gov (NCT03687970).

Abstract
Pressurized Intra-Peritoneal Aerosol Chemotherapy (PIPAC) is a novel laparoscopic intraperitoneal chemotherapy approach offered in selected patients affected by non-resectable peritoneal carcinomatosis. Drugs doses currently established for nebulization are very low: oxaliplatin (OXA) 120 mg/sm, cisplatin (CDDP) 10.5 mg/sm and doxorubicin (DXR) 2.1 mg/sm. A model-based approach for dose-escalation design in a single PIPAC procedure and subsequent dose escalation steps is planned. The starting dose of oxaliplatin is 100 mg/sm with a maximum estimated dose of 300 mg/sm; an escalation with overdose and under-dose control (for probability of toxicity less than 16% in case of under-dosing and probability of toxicity greater than 33% in case of overdosing) will be further applied. Cisplatin is used in association with doxorubicin: A two-dimensional dose-finding design is applied on the basis of the estimated dose limiting toxicity (DLT) at all combinations. The starting doses are 15 mg/sm for cisplatin and 3 mg/sm for doxorubicin. Safety is assessed according to Common Terminology Criteria for Adverse Events (CTCAE version 4.03). Secondary endpoints include radiological response according to Response Evaluation Criteria in Solid Tumor (version 1.1) and pharmacokinetic analyses. This phase I study can provide the scientific basis to maximize the optimal dose of cisplatin, doxorubicin and oxaliplatin applied as PIPAC.

Abstract
Introduction Combinations of 5-fluorouracil/leucovorin (5-FU/LV) with oxaliplatin (FOLFOX) or irinotecan (FOLFIRI) are part of standard treatments for metastatic colorectal cancer (mCRC). For these molecules, the impact of a low relative dose intensity (RDI) on survival is not sufficiently known in real-life. Material and methods Data were collected retrospectively from patients treated in our center for an unresectable mCRC with FOLFOX or FOLFIRI as a first-line treatment. To study the impact on progression-free survival (PFS) and overall survival (OS), patients were divided into high and low RDI according to the median RDI of 5-FU on one end, and the median RDI of oxaliplatin or irinotecan (OXA-IRI) on the other. Results In our population of 75 patients, the median age was 67.1 years and 77% of patients were treated with FOLFIRI. Patients with high RDI for OXA-IRI had better PFS compared to patients with low RDI (hazard ratio [HR], 0.58; p = 0.03). There was no statistically significant difference in PFS for patients with high RDI for 5-FU (HR, 0.66; p = 0.09). No difference was found in overall survival according to the RDI of OXA-IRI (HR, 0.72; p = 0.18) or 5-FU (HR, 0.77; p = 0.29). RDI had no significant impact on toxicities. Conclusions Our analysis suggests that a low RDI of oxaliplatin and irinotecan has a negative effect on PFS. RDI had no significant effect on OS in our cohort. The clinical benefit of maintaining high RDI in these patients appears low.

Abstract
BACKGROUND Randomized studies have shown low compliance to adjuvant chemotherapy in rectal cancer patients receiving preoperative chemotherapy and external beam radiation (CT/EBRT) with total mesorectal excision. We hypothesize that giving neoadjuvant CT before local treatment would improve CT compliance. METHODS Between 2010-2017, 180 patients were randomized (2:1) to either Arm A (AA) with FOLFOX x6 cycles prior to high dose rate brachytherapy (HDRBT) and surgery plus adjuvant FOLFOX x6 cycles, or Arm B (AB), with neoadjuvant HDRBT with surgery and adjuvant FOLFOX x12 cycles. The primary endpoint was CT compliance to ≥85% of full-dose CT for the first six cycles. Secondary endpoints were ypT0N0, five-year disease free survival (DFS), local control and overall survival (OS). RESULTS Patients were randomized to either AA (n = 120, median age (MA) 62 years) or AB (n = 60, MA 63 years). 175/180 patients completed HDRBT as planned (97.2%). In AA, two patients expired during CT; three patients post-randomization received short course EBRT because of progression under CT (n = 2, AA) or personal preference (n = 1, AB). ypT0N0 was 31% in AA and 28% in AB (p = 0.7). CT Compliance was 80% in AA and 53% in AB (p = 0.0002). Acute G3/G4 toxicity was 35.8% in AA and 27.6% in AB (p = 0.23). With a median follow-up of 48.5 months (IQR 33-72), the five-year DFS was 72.3% with AA and 68.3% with AB (p = 0.74), the five-year OS 83.8% for AA and 82.2% for AB (p = 0.53), and the five-year local recurrence was 6.3% for AA and 5.8% for AB (p = 0.71). CONCLUSION We confirmed improved compliance to neoadjuvant CT in this study. Although there is no statistical difference in ypT0N0 rate, local recurrence, and DFS between the two arms, a trend towards favourable oncological outcomes is observed.

Protective effect of the oral administration of cystine and theanine on oxaliplatin-induced peripheral neuropathy: a pilot randomized trial. Int J Clin Oncol 2020; 25:1814-1821. [PMID: 32594273 PMCID: PMC7498479 DOI: 10.1007/s10147-020-01728-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2020] [Accepted: 06/15/2020] [Indexed: 12/27/2022]
Abstract
BACKGROUND Oxaliplatin, one of the key cytotoxic drugs for colorectal cancer, frequently causes peripheral neuropathy which leads to dose modification and decreased patients' quality of life. However, prophylactic or therapeutic measures have not yet been established. Orally administered amino acids, cystine and theanine, promoted the synthesis of glutathione which was one of the potential candidates for preventing the neuropathy. The aim of this study was to determine whether daily oral administration of cystine and theanine attenuated oxaliplatin-induced peripheral neuropathy (OXLIPN). METHODS Twenty-eight colorectal cancer patients who received infusional 5-fluorouracil, leucovorin, and oxaliplatin (mFOLFOX6) therapy were randomly and evenly assigned to the cystine and theanine group and the control group. OXLIPN was assessed up to the sixth course using original 7-item questionnaire as well as Common Terminology Criteria for Adverse Events (CTCAE) grading scale. RESULTS Neuropathy scores according to our original questionnaire were significantly smaller in the cystine and theanine group at the fourth (p = 0.026), fifth (p = 0.029), and sixth course (p = 0.038). Furthermore, significant differences were also observed in CTCAE neuropathy grades at the fourth (p = 0.037) and the sixth course (p = 0.017). There was one patient in each group who required dose reduction due to OXLIPN. Except for neurotoxicity, no significant differences were noted in the incidence of adverse events, and the total amount of administered oxaliplatin. CONCLUSION The results demonstrated the daily oral administration of cystine and theanine attenuated OXLIPN.

[PMID: 32655636 PMCID: PMC7317329 DOI: 10.1155/2020/1701326] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Accepted: 06/01/2020] [Indexed: 12/21/2022]
Abstract
Background Oxaliplatin and irinotecan are generally used to treat advanced colorectal cancer (CRC) patients. Antibiotics improve the cytotoxicity of oxaliplatin but not irinotecan in a colon cancer cell line in vitro. This study retrospectively assessed whether antibiotics improve the treatment efficacy of oxaliplatin- but not irinotecan-based therapy in advanced CRC patients. Patients and Methods. The medical records of 220 advanced CRC patients who underwent oxaliplatin- or irinotecan-based therapy were retrospectively reviewed. The oxaliplatin and irinotecan groups were further divided into antibiotic-treated (group 1) and antibiotic-untreated (group 2) subgroups. Results In oxaliplatin groups 1 and 2, the response rate (RR) was 58.2% and 30.2%, while the disease control rate (DCR) was 92.5% and 64.2%, respectively; the median progression-free survival (PFS) was 10.5 months (95% confidence interval (CI) = 7.5–12.2) and 7.0 months (95% CI = 17.0–26.0), respectively, and the median overall survival (OS) was 23.8 months (95% CI = 5.1–9.1) and 17.4 months (95% CI = 13.1–24.9), respectively. In irinotecan groups 1 and 2, the RR was 17.8% and 20.0%, while the DCR was 75.6% and 69.1%, respectively; the median PFS was 8.2 months (95% CI = 6.2–12.7) and 7.9 months (95% CI = 12.0–23.0), respectively, and the median OS was 16.8 months (95% CI = 5.9–10.6) and 13.1 months (95% CI = 10.4–23.7), respectively. Conclusion To improve the treatment efficacy of oxaliplatin-based therapy in advanced CRC patients, adding antibiotics is a potential therapeutic option.

Abstract
BACKGROUND The presence of lymph node (LN) metastasis is a critical prognostic factor in colorectal cancer (CRC) patients and is also an indicator for adjuvant chemotherapy. The gold standard (GS) technique for LN diagnosis and staging is based on the analysis of haematoxylin and eosin (H&E)-stained slides, but its sensitivity is low. As a result, patients may not be properly diagnosed and some may have local recurrence or distant metastases after curative-intent surgery. Many of these diagnostic and treatment problems could be avoided if the one-step nucleic acid amplification assay (OSNA) was used rather than the GS technique. OSNA is a fast, automated, standardised, highly sensitive, quantitative technique for detecting LN metastases. OBJECTIVES The aim of this study was to assess the budget impact of introducing OSNA LN analysis in early-stage CRC patients in the Spanish National Health System (NHS). METHODS A budget impact analysis comparing two scenarios (GS vs. OSNA) was developed within the Spanish NHS framework over a 3-year time frame (2017-2019). The patient population consisted of newly diagnosed CRC patients undergoing surgical treatment, and the following costs were included: initial surgery, pathological diagnosis, staging, follow-up expenses, systemic treatment and surgery after recurrence. One- and two-way sensitivity analyses were performed. RESULTS Using OSNA instead of the GS would have saved €1,509,182, €6,854,501 and €10,814,082 during the first, second and third years of the analysis, respectively, because patients incur additional costs in later years, leading to savings of more than €19 million for the NHS over the 3-year time horizon. CONCLUSIONS Introducing OSNA in CRC LN analysis may represent not only an economic benefit for the NHS but also a clinical benefit for CRC patients since a more accurate staging could be performed, thus avoiding unnecessary treatments.

Phase I/II study of oxaliplatin dose escalation via a laparoscopic approach using pressurized aerosol intraperitoneal chemotherapy (PIPOX trial) for nonresectable peritoneal metastases of digestive cancers (stomach, small bowel and colorectal): Rationale and design. Pleura Peritoneum 2018; 3:20180120. [PMID: 30911664 PMCID: PMC6404986 DOI: 10.1515/pp-2018-0120] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2018] [Accepted: 08/22/2018] [Indexed: 01/17/2023] Open
Abstract
Background The annual incidence of gastrointestinal carcinomas (stomach, small bowel, colon and rectum) is increasing in Western countries, reaching 50,000 new cases each year in France. Peritoneal carcinomatosis (PC) is diagnosed in 15% of these patients. Complete cytoreductive surgery (CCS) plus Hyperthermic IntraPeritoneal Chemotherapy (HIPEC) is the only therapy that can offer patients with PC a chance for long-term survival with a 5 year overall survival (OS) rate of 30–60% versus 0–5% with systemic chemotherapy alone. However, CCS plus HIPEC still presents serious limitations and very few patients (10%) are candidates for these radical treatments. PC remains a palliative setting for 90% of patients with a median survival ranging from 15 to 25 months. Innovative surgical therapies such as Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) therefore need to be developed to improve the prognosis. Potential benefits were obtained after intraperitoneal nebulization of oxaliplatin in patients with advanced PC from colorectal cancer. Innovative surgical therapies such as pressurized intraperitoneal aerosol chemotherapy (PIPAC) have been proposed as palliative locoregional treatment with some promising results. The dose of oxaliplatin currently established by nebulization (PIPAC) is really low at 92 mg/m2. However, the peritoneum acts as a barrier limiting the systemic passage of intraperitoneal drug. Oxaliplatin used at higher doses during PIPAC procedures could be a safe option and allow better intratumoral penetration of chemotherapy. Method and design The proposed study is a multicenter phase I/II trial of oxaliplatin dose escalation during PIPAC. The aim is to determine the maximum tolerated dose of pressurized oxaliplatin administered by the intraperitoneal route (PIPAC) during two consecutive procedures at a 4–6 week interval for patients with extended peritoneal carcinomatosis from the gastrointestinal tract. Dose started at 90 mg/m2 and escalation was in 50 mg/m2 steps up to a maximum of 300 mg/m2. Discussion Oxaliplatin is an effective drug in gastrointestinal cancer and high doses given by the intraperitoneal route during HIPEC are well tolerated. In this phase I trial, we hypothesized that high-dose oxaliplatin during PIPAC is feasible and safe. The repeated local administration of high doses of oxaliplatin could improve tumor response and prognosis. Trial registration Prospective study. ClinicalTrials.gov: NCT03294252.

Abstract
Aims and background The addition of oxaliplatin to the widely employed De Gramont schedule (FOLFOX regimen) in patients with metastatic colorectal cancer improved their outcome with a moderate toxicity pattern. The adaptation of the delivery rate of 5-fluorouracil, leucovorin and oxaliplatin to circadian rhythms (chronotherapy) resulted in a very high drug tolerability with clinical results at least comparable to those achieved with the FOLFOX regimen. However, chronomodulated infusion seemed to be more expensive, requiring dedicated electronic pumps and several disposable materials. The present study aimed to compare the direct costs of the two regimens and to determine whether chronotherapy was effectively more expensive than the FOLFOX regimen. Study design The direct costs of drug delivery devices derived from various publicly available sources and of toxicity management as extrapolated from two published studies considering comparable patient subsets were added and compared. Results Pump, central venous system and disposable materials for a single chronotherapy cycle were € 193 or € 212 according to whether the pumps were bought or rented, compared to € 58 for the FOLFOX regimen. Toxicity management costs were € 144 vs € 288 for the two schemes, respectively. Globally, a single course of chronotherapy cost € 337 or € 356, whereas a single FOLFOX cycle cost € 346. Conclusions Direct costs for a single chronotherapy cycle appeared to be comparable to a single course of the FOLFOX regimen. In fact, the major material cost of chronochemotherapy devices was balanced by a better tolerability profile. The overall improvement in quality of life with chronochemotherapy affecting indirect costs, such as reduction of work, and intangible costs is worthy of further pharmacoeconomic attention.

Abstract
BACKGROUND 5-Fluorouracil (5FU), Folinic acid (FA), and Oxaliplatin (FOLFOX) or 5FU, FA, and Irinotecan (FOLFIRI) are standard regimens for palliative chemotherapy of metastatic colon cancer. Since data showing the influence of dose reduction in palliative treatment are rare, the objective of this single center, retrospective study was to further characterize the influence of dose reduction on efficacy of these therapeutic regimens. METHODS One hundred nine patients, diagnosed with stage IV colon cancer between 2004 and 2012 and receiving palliative first-line chemotherapy with either FOLFOX or FOLFIRI regimens in our outpatient clinic were analyzed for treatment efficacy. Patients who received dose reductions due to side effects usually received doses of 80% or lower of per protocol dose. Survival data were obtained from the Regensburg Tumor Registry. Survival analysis was performed using Kaplan-Meier statistical analysis and multivariable analysis. RESULTS A dose reduction due to side effects was necessary in 46 (42%) patients. Dose reduction was independent of age. Major reasons for dose reduction were neutropenia (30%) followed by polyneuropathy (16%) and diarrhea (14%). Dosage was more often reduced in patients receiving FOLFOX based therapy. Comparison of patients with dose reduction versus patients with full dosage showed no significant difference on overall survival (p = 0.430). Subgroup analysis revealed dose reduction in patients with N2 stage disease was associated with improved survival. Patients who underwent dose reduction received more cycles of chemotherapy (13.7 vs. 10.8 cycles) and cumulative dosage was similar in both groups. CONCLUSION Contrary to our expectations, the need to reduce chemotherapy dosage due to side effects does not indicate a worse prognosis in our retrospective analysis. We believe this can in part be explained by better adaption to interindividual pharmacokinetics and longer time of treatment.

Radiofrequency and Microwave Ablation Compared to Systemic Chemotherapy and to Partial Hepatectomy in the Treatment of Colorectal Liver Metastases: A Systematic Review and Meta-Analysis. Cardiovasc Intervent Radiol 2018; 41:1189-1204. [PMID: 29666906 PMCID: PMC6021475 DOI: 10.1007/s00270-018-1959-3] [Citation(s) in RCA: 120] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2017] [Accepted: 04/05/2018] [Indexed: 12/18/2022]
Abstract
Purpose To assess safety and outcome of radiofrequency ablation (RFA) and microwave ablation (MWA) as compared to systemic chemotherapy and partial hepatectomy (PH) in the treatment of colorectal liver metastases (CRLM). Methods MEDLINE, Embase and the Cochrane Library were searched. Randomized trials and comparative observational studies with multivariate analysis and/or matching were included. Guidelines from National Guideline Clearinghouse and Guidelines International Network were assessed using the AGREE II instrument. Results The search revealed 3530 records; 328 were selected for full-text review; 48 were included: 8 systematic reviews, 2 randomized studies, 26 comparative observational studies, 2 guideline-articles and 10 case series; in addition 13 guidelines were evaluated. Literature to assess the effectiveness of ablation was limited. RFA + systemic chemotherapy was superior to chemotherapy alone. PH was superior to RFA alone but not to RFA + PH or to MWA. Compared to PH, RFA showed fewer complications, MWA did not. Outcomes were subject to residual confounding since ablation was only employed for unresectable disease. Conclusion The results from the EORTC-CLOCC trial, the comparable survival for ablation + PH versus PH alone, the potential to induce long-term disease control and the low complication rate argue in favour of ablation over chemotherapy alone. Further randomized comparisons of ablation to current-day chemotherapy alone should therefore be considered unethical. Hence, the highest achievable level of evidence for unresectable CRLM seems reached. The apparent selection bias from previous studies and the superior safety profile mandate the setup of randomized controlled trials comparing ablation to surgery.

Abstract
Purpose An oxaliplatin-based regimen is the most common adjuvant chemotherapy for patients with stage II/III colorectal cancer, but many patients experience dose reduction or early termination of chemotherapy due to side effects. We conducted this study to verify the range of reduction with oncologic safety. Methods Patients with stage II/III colorectal cancer who received adjuvant FOLFOX chemotherapy were enrolled in this study. The total amount of oxaliplatin administered per patient was calculated as a percentile based on 12 cycles of full-dose FOLFOX as a standard dose. The cutoff values showing significant differences in survival were calculated, and the clinicopathologic outcomes of patient groups classified by the value were compared. Results Among a total of 611 patients, there were 107 stage II patients, and 504 stage III patients. At 60% of the standard dose of oxaliplatin, the patients in the dose reduction group were older (62 years vs. 58 years, P = 0.003), had lower body mass index (BMI) (23.1 kg/m2vs. 24.0 kg/m2, P = 0.005), and were more exposed to neoadjuvant treatment (18.0% vs. 9.1%, P = 0.003) in comparison to the standard group. At 60% of the standard dose, there were no significant differences in 5-year disease-free survival (DFS) and overall survival (OS) between the 2 groups (5-year DFS: 73.5% vs. 74.2%, P = 0.519; 5-year OS: 71.9% vs. 81.5%, P = 0.256, respectively). Conclusion Patients with old age, low BMI, and more frequent exposure to neoadjuvant treatment tended to show lower compliance with chemotherapy. More than 60% dose should be administered to patients with stage II/III colorectal cancer as adjuvant chemotherapy to achieve acceptable oncologic outcomes.

Abstract
We determined the gene expression profiles for 48 ATP binding cassette (ABC) transporters in matched colon cancer and normal colon tissues in order to provide insight into the mechanisms underlying expression of transporters related to colon carcinogenesis. The expression of ABCB1,ABCC1,ABCC2,ABCC3, and ABCG2 was altered in association with colon carcinogenesis. Among these transporters, the expression of ABCC3 was repressed by Wnt signaling pathway in colon cancer cell lines. Knockdown of the pathway components transcription factor 7‐like 2 (TCF7L2) or β‐catenin thus increased ABCC3 expression, whereas activation of Wnt signaling with inhibitors of glycogen synthase kinase–3β (GSK‐3β) reduced it. ChIP and luciferase reporter assays also showed that TCF7L2 binds to the ABCC3 locus and regulates its expression. Finally, overexpression of ABCC3 in colon cancer cells conferred resistance to anticancer drug‐induced cytotoxicity. Our data thus suggest that Wnt signaling represses ABCC3 expression during colon carcinogenesis, and that subsequent upregulation of ABCC3 expression during drug treatment might contribute to acquired drug resistance.

Abstract
Introduction The omphalomesenteric duct (OMD) or the vitelline duct (VD) is the embryonic structure connecting the vitelline sac to the primitive gut. It undergoes obliteration at 5–9 weeks of gestation. Failure of this duct to close, which occurs in approximately 2% of the population, can lead to various types of VD residual diseases. A persistent OMD remnant is pathological, and it typically presents in the pediatric population. Meckel diverticulum is the most common anomaly that results from failure of resorption of the OMD. In extremely rare instances, OMD remnant adenocarcinomas have been reported in the adult population. Case description In this study, we present a case of OMD remnant adenocarcinoma with axillary lymph node metastases in an adult male. Discussion and Evaluation Because OMD remnant adenocarcinoma is rare, few relevant studies have been reported. The final diagnosis of navel VD residual adenocarcinoma depends on postoperative pathology and immunohistochemical analysis. The follow-up treatment in OMD is similar to the chemotherapy regimens of postoperative gastrointestinal malignant tumors. Conclusions In this report, the patient experienced no complications after surgery and was discharged on the seventh postoperative day, followed by 12 courses of postoperative FOLFOX6 scheme chemotherapy. By the end of chemotherapy, the patient had no evidence of recurrent disease and metastasis across the reexamination of PET–CT.

Abstract
Background The aim of this study was to examine the specific chemoregimens selected for adjuvant therapy in the patients with stage III colon cancer. We investigated the trends in chemotherapeutic prescribing patterns and looked for adequate therapeutic setting for these patients. Methods 288 patients presenting with stage III colon cancer and undergoing adjuvant therapies after curative surgery for more than 3-month were enrolled between January 2006 and December 2011. Demographic characteristics and therapeutic factors were analyzed, including age, gender, histological grade, tumor sizes, tumor location, pathologic stage, performance status, serum carcinoembryonic antigen, regimens selection, interval from the operation to the start of adjuvant therapy and prolonged adjuvant therapy. Kaplan– Meier methods were utilized for drawing survival curves and Cox model was used to analyze survival, prognostic factors. Results The analysis showed that the patients aged under 70 received more intensive therapies than those aged over 70 (P<0.001). Later, advanced analysis in therapeutic factors was conducted between the patients aged under 70 and those over 70. In the patients aged under 70, significant differences in 4-year overall survival (OS) were noted between UFUR (oral tegafur-uracil plus leucovorin) groups and FOLFOX (5-FU plus oxaliplatin) [65.6% versus (vs) 89.8%, relative risk (RR) 3.780, 95% confidence interval (CI) 1.263–11.315, P = 0.017]. There were also differences in 4-year OS between these patients with and without oxaliplatin-contained regimens (92.1% vs 83.4%, respectively, RR 0.385, 95% CI 0.157–0.946, P = 0.037). In addition, the patients who received intravenous or combined therapy also had higher 4-year OS than those only received oral regimens (92.1% vs 76.6%, P = 0.077), though the finding did not reach statistical significance. In contrast to the survival benefits of above therapeutic settings for the patients aged under 70, there was less advantage in the old patients when they received intensive therapies or even oxaliplatin-contained regimens. Prolonged cycles of adjuvant therapy resulted in no significant benefit to survival rates regardless of ages. Conclusions The adequate individualized therapeutic strategy plays an important role for stage III colon cancer. Our findings suggested that benefit of oxaliplatin-contained therapy is limited to patients aged under 70 and oral fluoropyrimidines may be an effective option for old patients. In addition, prolonged adjuvant setting is suggested to be unbeneficial for managing stage III colon cancer.

Abstract
PURPOSE Geographic access to care may be associated with receipt of chemotherapy but has not been fully examined. This study sought to evaluate the association between density of oncologists and travel distance and receipt of adjuvant chemotherapy for colon cancer within 90 days of colectomy. PATIENTS AND METHODS Patients in the National Cancer Data Base with stage III colon cancer, diagnosed between 2007 and 2010, and age 18 to 80 years were selected. Generalized estimating equation clustering by hospital service area was conducted to examine the association between geographic access and receipt of oncology services, controlling for patient sociodemographic and clinical characteristics. RESULTS Of 34,694 patients in the study cohort, 75.7% received adjuvant chemotherapy within 90 days of colectomy. Compared with travel distance less than 12.5 miles, patients who traveled 50 to 249 miles (odds ratio [OR], 0.87; P=.009) or ≥250 miles (OR, 0.36; P<.001) had decreased likelihood of receiving adjuvant chemotherapy. Density level of oncologists was not statistically associated with receipt of adjuvant chemotherapy (low v high density: OR, 0.98; P=.77). When stratifying analyses by insurance status, non-privately insured patients who resided in areas with low density of oncologists were less likely to receive adjuvant chemotherapy (OR, 0.85; P=.03). CONCLUSION Increased travel burden was associated with a decreased likelihood of receiving adjuvant chemotherapy, regardless of insurance status. Patients with nonprivate insurance who resided in low-density oncologist areas were less likely to receive adjuvant chemotherapy. If these findings are validated prospectively, interventions to decrease geographic barriers may improve the timeliness and quality of colon cancer treatment.

Abstract
PURPOSE Adjuvant folinic acid, fluorouracil, and oxaliplatin (FOLFOX) chemotherapy for resected high-risk colon cancer is associated with a low risk of febrile neutropenia (FN). Neutropenia, however, is a common cause of dose modification or delay with unknown consequences on outcomes. We examined the effect of neutropenia-related and other dose-limiting toxicities and relative dose intensity of oxaliplatin and 5-FU, on relapse-free and overall survival in patients treated with FOLFOX chemotherapy for resected high-risk colon cancer. METHODS A chart review was conducted on patients treated at the British Columbia Cancer Agency receiving ≥1 cycle of mFOLFOX6 chemotherapy for resected stage II or III colon cancer between January 1, 2006, and December 31, 2007. Relapse-free survival (RFS) and overall survival (OS) were analyzed by the Kaplan-Meier method. RESULTS One hundred fourteen patients (median age 59 years, 44 % male, 98 % stage III, median follow-up 5.2 years) were included. Ninety percent of the patients experienced any dose-limiting toxicity (DLT), while 58 % of the patients had a neutropenia-related DLT. There were no documented episodes of FN. Granulocyte colony-stimulating factor (GCSF) was used in 10 % of the patients. Median relative dose intensity (RDI) was 81 and 85 % for oxaliplatin and 5-FU, respectively. Oxaliplatin and 5-FU RDI were not associated with RFS or OS when analyzed as continuous variables or categorically. Grade II or grade III/IV neutropenia compared to no neutropenia was not associated with RFS or OS. CONCLUSIONS DLTs affect the majority of patients on adjuvant FOLFOX for high-risk colon cancer, but RFS and OS do not appear to be affected by the associated lower RDI of oxaliplatin and 5-FU.

Abstract
Oxaliplatin, although related to cisplatin and carboplatin, has a more favorable toxicity profile and may offer advantages in combination regimens. We combined oxaliplatin, ifosfamide, and etoposide (IOE) and estimated the regimen's maximum tolerated dose (MTD) in children with refractory solid tumors. Dose-limiting toxicity (DLT) and MTD were assessed at 3 dose levels in a 21-day regimen: day 1, oxaliplatin 130 mg/m (consistent dose); days 1 to 3, ifosfamide 1200 mg/m/d (level 0) or 1500 mg/m/d (levels 1 and 2) and etoposide 75 mg/m/d (levels 0 and 1) or 100 mg/m/d (level 2). Course 1 filgrastim/pegfilgrastim was permitted after initial DLT determination, if neutropenia was dose limiting. Seventeen patients received 59 courses. Without filgrastim (n=9), DLT was neutropenia in 2 patients at dose level 1. No DLT was observed after adding filgrastim (n=8). There was no ototoxicity, nephrotoxicity >grade 1, or neurotoxicity >grade 2. One patient experienced a partial response and 9 had stable disease after 2 courses. In conclusion, the IOE regimen was well tolerated. Without filgrastim, neutropenia was dose limiting with MTD at ifosfamide 1200 mg/m/d and etoposide 75 mg/m/d. The MTD with filgrastim was not defined due to early study closure. Filgrastim allowed ifosfamide and etoposide dose escalation and should be included in future studies.

Abstract
OBJECTIVE To investigate the clinical utility of the Combination of Platelet count and Neutrophil to Lymphocyte Ratio (COP-NLR) for predicting the postoperative survival of patients undergoing surgery for gastric cancer (GC). METHODS The COP-NLR was calculated on the basis of data obtained on the day of admission as follows: patients with both an elevated platelet count (>300 × 10(3) /µl) and an elevated NLR (>3) were allocated a score of 2, and patients showing one or neither were allocated a score of 1 or 0, respectively. Five hundred forty-four patients for whom data were sufficient to allow analysis of the relationship between clinicolaboratory characteristics and postoperative survival were enrolled. RESULTS Multivariate analysis using the 12 clinical characteristics selected by univariate analyses revealed that the COP-NLR was associated with OS (hazard ratio, 1.781; 95% C.I., 1.094-2.899; P = 0.020) along with age, tumor type, lymph node metastasis and albumin level. Kaplan-Meier analysis and log rank test demonstrated significant differences in both OS and cancer-specific survival among patients with COP-NLR 0, 1, and 2 (P < 0.001). CONCLUSION The COP-NLR is able to predict postoperative survival of patients with GC and classify such patients into three independent groups before surgery.

Abstract
PURPOSE This study was designed to evaluate (1) the impact of relative dose intensity (RDI) on tumor response and survival outcomes and (2) the influence of dose reduction and schedule modification on outcomes in patients with metastatic colorectal cancer (mCRC). METHODS Pooled datasets from two previous phase II trials of FOLFIRI (CCOG-0502; n = 36) and mFOLFOX6 (CCOG-0704; n = 30) in patients with mCRC were analyzed retrospectively. The RDIs of irinotecan and oxaliplatin were compared to response rate (RR), disease control rate (DCR), progression-free survival (PFS) and overall survival (OS). To assess the effects of dose reduction and schedule modification, the effects of dose index (DI) and time index (TI) on outcomes were evaluated. RESULTS The median RDIs of irinotecan in FOLFIRI and oxaliplatin in mFOLFOX6 were 80 and 79 %, respectively. Higher RDI of irinotecan in FOLFIRI was associated with significant improvements in RR (65 vs. 6 %, p < 0.01), DCR (100 vs. 59 %, p < 0.01), PFS (9.9 vs. 5.6 months, p < 0.01) and OS (26.7 vs. 12.9 months, p = 0.01) and was the only independent factor associated with PFS [hazard ratio (HR) 8.48, p < 0.01). Higher RDI of oxaliplatin in FOLFOX was significantly associated with DCR (65 vs. 6 %, p < 0.01), and higher TI of oxaliplatin was the only independent factor associated with PFS (HR 2.74, p = 0.04). CONCLUSION RDIs of irinotecan and oxaliplatin affected clinical outcomes. Dose reductions in irinotecan, as indicated by DI, and time delays in oxaliplatin, as indicated by TI, were the only independent prognostic factors predicting PFS in patients receiving FOLFIRI and FOLFOX6, respectively.

Abstract
PURPOSE Important developments in chemotherapy for advanced colorectal cancer over the past 15 years are reviewed, with an emphasis on the most recently published data from clinical trials of newer multidrug regimens, administration techniques, and dosing schedules. SUMMARY Eight agents are approved by the Food and Drug Administration (FDA) for use in treating patients with advanced colorectal cancer. Fluorouracil and leucovorin still constitute the foundation of most chemotherapy regimens for this population; combination fluorouracil-leucovorin therapy plus either irinotecan (the FOLFIRI regimen) or oxaliplatin (the FOLFOX regimen) are two firmly established first-line treatments shown to produce similar outcomes. In Phase III trials conducted over the past six to seven years, regimens of capecitabine plus oxaliplatin (CapeOx) were demonstrated to have clinical effectiveness comparable to that of FOLFOX therapy. Response rates of 35-55% and median overall survival of ≥20 months have been documented with some of the newer regimens. Research to define the optimal role of the three monoclonal antibody agents approved by FDA for use in managing advanced colorectal cancer is ongoing; bevacizumab has been shown to confer significant survival benefits when added to certain chemotherapy regimens, and other monoclonal antibodies (cetuximab and panitumumab) also appear to offer significant benefits in select patients as first- or second-line therapies. CONCLUSION Over the past 15 years, a shift toward multiagent treatment strategies including a variety of chemotherapy agents and monoclonal antibodies has yielded improved rates of response and prolonged survival among patients with advanced colorectal cancer. The CapeOx, FOLFOX, and FOLFIRI regimens are currently among the most widely used first-line treatments.

Abstract
We report a case of acute inflammatory demyelinating polyradiculoneuropathy (AIDP) that developed in a patient with cholangiocarcinoma after receiving oxaliplatin-based chemotherapy. A 62-year-old man had multiple hypodense lesions with delayed enhancement in the both lobes of the liver on abdominal computed tomography. He was treated with 5-fluorouracil, leucovorin and oxaliplatin (100 mg/m(2)). After eight cycles of treatment and a cumulative oxaliplatin dose of 780 mg/m(2), he developed an unsteady gait, dysphagia, weakness of both the upper and lower limbs and impairment of all sensory modalities. Nerve conduction studies confirmed the diagnosis of AIDP. Immunoglobulin G i.v. was administered for 5 days but the neurological deficits of both his upper and lower limbs did not improve. This case highlights unusual peripheral nervous system manifestations in a patient who received chemotherapy with oxaliplatin.

Abstract
BACKGROUND Chemotherapy-induced peripheral neuropathy is a serious side effect in cancer treatment, a major manifestation being neuropathic pain that can be debilitating and can reduce the quality of life of the patient. Oxaliplatin and taxol are common anti-cancer drugs that induce neuropathic pain by an unknown mechanism. We tested the hypothesis that satellite glial cells in dorsal root ganglia (DRGs) are altered in chemotherapy-induced peripheral neuropathy models and contribute to neuropathic pain. METHODS Mice were injected with either oxaliplatin or taxol and examined at 7-30 days. Glial fibrillary acidic protein (glial activation marker) expression was determined by immunohistochemistry. Satellite glial cells in isolated DRG were injected with the fluorescent dye Lucifer yellow and the incidence of dye coupling among these cells that surround different neurons was quantified. RESULTS Taxol or oxaliplatin increased glial fibrillary acidic protein expression in satellite glial cells. Gap junction-mediated coupling between satellite glial cells was increased by up to fivefold after oxaliplatin and by up to twofold after taxol. This is consistent with work on other pain models showing that augmented satellite glial cell coupling contributes to chronic pain. Administration of the gap junction blocker carbenoxolone to chemotherapy-treated mice produced an analgesic-like effect. CONCLUSIONS We propose that increased coupling by gap junctions is part of satellite glial cell activation, and that augmented coupling contributes to the lowering of pain threshold in oxaliplatin- and taxol-treated mice. We further propose that gap junction blockers may have potential in treating chemotherapy-induced neuropathic pain.

Abstract
Colorectal cancer is the second most common cause of cancer related deaths in the United States. Recent developments have led to prolonged survival with the use of sequential lines of chemotherapy agents. The addition of bevacizumab to active chemotherapy has further improved survival when used in the first and second lines of therapy for metastatic colorectal cancer. Evidence supporting the continued use of bevacizumab throughout lines of therapy is accumulating. Clinical trials are underway in which bevacizumab is continued beyond the first line of a chemotherapy and bevacizumab combination regimen. The mechanism by which colorectal cancer may become resistant to bevacizumab is poorly understood. Molecular and biochemical correlates which may identify bevacizumab resistance are an important component in the design of these clinical trials.

Abstract
A regimen consisting of 5-fluorouracil/leucovorin plus oxaliplatin (FOLFOX-6) is widely used in France in the first-line treatment of metastatic colorectal cancer (MCRC). The aim of our study was to demonstrate the non-inferiority of capecitabine plus oxaliplatin (XELOX) versus FOLFOX-6 for this indication. Patients were randomly assigned to receive XELOX or FOLFOX-6 for 6 months. The primary endpoint was overall response rate (ORR) in the per-protocol (PP) population; however, progression-free and overall survival (OS), time to response and response duration were also assessed. A total of 306 patients were enrolled (XELOX n = 156; FOLFOX-6 n = 150). ORR was 42 and 46% with XELOX and FOLFOX-6, respectively, in the PP population. The difference between groups was 4.7%; the upper limit of the unilateral 95% confidence interval (14.4%) was below the non-inferiority margin of 15%. In the intent-to-treat population, median progression-free survival was 8.8 months with XELOX and 9.3 months with FOLFOX-6, and median OS was 19.9 and 20.5 months, respectively. XELOX patients had significantly more grade 3/4 thrombocytopenia (12% vs. 5%) and diarrhoea (14% vs. 7%), but significantly less grade 3/4 neutropenia (5% vs. 47%), febrile neutropenia (0% vs. 6%) and neuropathy (11% vs. 26%) than FOLFOX-6 patients. We conclude that XELOX is non-inferior in terms of efficacy to FOLFOX-6 in the first-line treatment of MCRC, but has a different toxicity profile.

Abstract
PURPOSE To assess the safety and efficacy of oxaliplatin (OXA) plus dual inhibition of thymidilate synthase during preoperative pelvic radiotherapy (RT) in patients with poor prognosis for rectal carcinoma. METHODS AND MATERIALS Sixty-three patients with the following characteristics, a clinical (c) stage T4, cN1-2, or cT3N0 of ≤5 cm from the anal verge and/or with a circumferential resection margin (CRM) of ≤5 mm (by magnetic resonance imaging), received three biweekly courses of chemotherapy with OXA, 100 mg/m2; raltitrexed (RTX), 2.5 mg/m2 on day 1, and 5-fluorouracil (5-FU), 900 mg/m2 (31 patients) or 800 mg/m2 (32 patients); levo-folinic acid (LFA), 250 mg/m2 on day 2, during pelvic RT (45 Gy). Pathologic response was defined as complete pathological response (ypCR), major (tumor regression grade(TRG) 2 to 3, with ypCRM-ve and ypN-ve) or minor or no response (TRG4 to -5, or ypCRM+ve, or ypN+ve). Adjuvant 5-FU/LFA regimen was given in cases of cT4, ypN+ve, or ypCRM+ve. RESULTS Overall, neutropenia (40%) and diarrhea (13%) were the most common grade≥3 toxicities, and tolerability was better with a 5-FU dose reduction. No significant difference in pathologic response was seen according 5-FU dosage: overall, a ypCR was obtained in 24 (39%) patients, and a major response in 20 (32%) patients. The 5-year probability of freedom from recurrence was 80% (95% confidence interval, 68%-92%); it was 56% for the minor/no response group, while it was around 90% for both the ypCR and the major response group. CONCLUSIONS OXA, RTX, and 5-FU/LFA administered during pelvic RT produced promising early and long-term results in rectal carcinoma patients with poor prognosis. The postoperative treatment strategy applied in our study supports the risk-adapted approach in postoperative management.

Abstract
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT * Numerous clinical studies, including a few prospective ones, have reported conflicting results on the impact of gene polymorphisms related to fluorouracil (FU) and oxaliplatin pharmacodynamics. WHAT THIS STUDY ADDS * This prospective study is the first to report that clinical response to FOLFOX is significantly related to methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms (677C-->T and 1298A-->C), with a response rate of 37, 53, 63 and 80% in patients harbouring no, one, two or three favourable MTHFR alleles, respectively. * Only polymorphisms of genes related to oxaliplatin pharmacodynamics (GSTpi 105Ile-->Val and XPD 751Ly-->Gln) influenced progression-free survival. * These results corroborate the observation that response was related to the cumulative FU dose, whereas progression-free survival was related to the cumulative oxaliplatin dose. AIMS To test prospectively the predictive value of germinal gene polymorphisms related to fluorouracil (FU) and oxaliplatin (Oxa) pharmacodynamics on toxicity and responsiveness of colorectal cancer (CRC) patients receiving FOLFOX therapy. METHODS Advanced CRC patients (n= 117) receiving FOLFOX 7 therapy were enrolled. Gene polymorphisms relevant for FU [thymidylate synthase (TYMS, 28 bp repeats including the G-->C mutation + 6 bp deletion in 3'UTR), methylenetetrahydrofolate reductase (MTHFR, 677C-->T, 1298A-->C), dihydropyrimidine deshydrogenase (IVS14+1G-->A) and Oxa: glutathione S-transferase (GST) pi (105Ile-->Val, 114Ala-->Val), excision repair cross-complementing group 1 (ERCC1) (118AAT-->AAC), ERCC2 (XPD, 751Lys-->Gln) and XRCC1 (399Arg-->Gln)] were determined (blood mononuclear cells). RESULTS None of the genotypes was predictive of toxicity. Response rate (54.7% complete response + partial response) was related to FU pharmacogenetics, with both 677C-->T (P= 0.042) and 1298A-->C (P= 0.004) MTHFR genotypes linked to clinical response. Importantly, the score of favourable MTHFR alleles (677T and 1298C) was positively linked to response, with response rates of 37.1, 53.3, 62.5 and 80.0% in patients bearing no, one, two or three favourable alleles, respectively (P= 0.040). Polymorphisms of genes related to Oxa pharmacodynamics showed an influence on progression-free survival, with a better outcome in patients bearing GSTpi 105 Val/Val genotype or XPD 751Lys-containing genotype (P= 0.054). CONCLUSIONS These results show that response to FOLFOX therapy in CRC patients may be driven by MTHFR germinal polymorphisms.

Abstract
PURPOSE Treatment options for patients with advanced gastric cancer remain limited. Few studies have investigated the efficacy and tolerability of the combination regimen of oxaliplatin and 5-fluorouracil with leucovorin for patients with advanced gastric cancer. The goal of this study was to examine the efficacy and toxicity of a modified FOLFOX-6 (mFOLFOX-6) regimen as a first-line chemotherapy regimen for patients with advanced gastric cancer. MATERIALS AND METHODS From March, 2006, to December, 2007, 82 patients with advanced gastric cancer received 100 mg/m² oxaliplatin and 100 mg/m² leucovorin on the first day of treatment, followed by 2,400 mg/m² of 5-fluorouracil on the first and second days of treatment every 2 weeks as a first-line treatment. RESULTS The median age of the enrolled patients was 62 years (range; 30~75). Out of 82 patients, 34 cases (41.5%) were recurrent cases after curative resection, and the other 48 cases were unresectable or non-curative resectable cases. Their response was evaluated every 6 weeks. The overall response rate was 40.2%, with 2 (2.4%) complete response and 31 (37.8%) partial responses. The median time to progression (TTP) and overall survival (OS) time were 6.0 months (95% confidence interval [CI]: 4.69~7.31) and 13.0 months (7.99~18.0), respectively. The grade 3~4 hematologic toxicities observed included neutropenia (34.1%), thrombocytopenia (7.3%), and anemia (1.2%). The gastrointestinal toxicities observed included grade 3~4 nausea (9.8%) and vomiting (7.3%). Six patients (7.3%) experienced grade 3 neuropathy. No treatment-related deaths were recorded. CONCLUSION The modified FOLFOX-6 regimen is effective and well tolerated as a first-line chemotherapy regimen for patients with advanced gastric cancer.

Abstract
We present a case of duodenal carcinoma, 12 cm in size, with severe stenosis at the second portion of the duodenum. When the patient developed obstructive jaundice, it was impossible to perform endoscopic biliary drainage by standard cannulation due to the stenosis, but was succeeded by wire-guided cannulation using papillotome. Histology of the tumor showed undifferentiated carcinoma without differentiation to any specific cell type. Systemic chemotherapy was started with 5-FU, leucovorin and oxaliplatin. Biliary stent worked well until the patient succumbed three months after. Herein we demonstrate the new advantage of wire-guided cannulation in case of duodenal stenosis.

Abstract
PURPOSE S-1 showed clinical activity in colorectal cancer, and the preclinical data of S-1 with oxaliplatin showed synergistic activity in an animal model. This phase I study was conducted to determine the maximum tolerated dose of S-1 with oxaliplatin and to define its recommended dose for the subsequent phase II study. MATERIALS AND METHODS Patients with untreated colorectal adenocarcinoma were eligible in this study if they had measurable lesions. S-1 was administered on days 1-14, with doses starting from 60 mg/m2 per day and escalating by 10 mg/m2 at each dose level. Oxaliplatin was given at the fixed dose of 130 mg/m2, through 2-h i.v. infusion on day 1. The treatment was repeated every 3 weeks. RESULTS A total of 27 patients received six different S-1 dose levels. The dose-limiting toxicities (DLTs) were neutropenia, diarrhea, and vomiting. At dose level 5 (100 mg/m2), two patients experienced DLTs, while none of the third cohorts did. At dose level 6 (110 mg/m2), two patients experienced DLTs, and one of them died from treatment-related toxicity. The accrual was then stopped. CONCLUSIONS The recommended dose is S-1 100 mg/m2 on days 1-14, with 130 mg/m2 oxaliplatin on day 1, every 3 weeks. This regimen is proposed for the phase II study.

Abstract
This phase II study examined bimonthly oxaliplatin (85 mg/m2) added to a continuous infusion of fluorouracil (3000 mg/m2 for 46 h following a 400 mg/m2 bolus), with leucovorin (LV) (150 mg/m2) administrated in a simplified way to patients with metastatic colorectal cancers (CRC) refractory or resistant to 5-fluorouracil (5-FU). Sixty patients were registered. Of the 52 evaluable patients, 3 (5.8%) achieved a complete response (CR) and 18 (34.6%) achieved a partial response (PR). The overall response rate (CR + PR) was 40.4% (95% confidence interval [CI]: 26.6%-54.2%) for evaluable patients and 35% (95% CI: 22.6%-47.4%) by intention to treat. The median progression-free survival (PFS) was 5.2 months, and the median survival was 14.2 months. No significant differences were seen in response rates and PFS of patient groups pretreated either with high-dose 5-FU/LV by continuous infusion or with intravenous 5-FU/LV by a weekly bolus. From the 421 cycles analyzed, dose-limiting toxicities included cumulative sensory neuropathy and leukopenia, accounting for 11.6% and 10.0%, National Cancer Institute-Common Toxicity Criteria grade 3/4 toxicities per patient, respectively. Two (3.3%) patients experienced hepatic encephalopathy related to high-dose 5-FU. With necessary caution, this regimen was effective for 5-FU-pretreated CRC, regardless of ethnic differences, and it had the advantage of LV being administrated at a low dose in a simplified way.

Abstract
PURPOSE Neurotoxicity is becoming increasingly recognized as the major dose-limiting toxicity of oxaliplatin. Because the mechanism of oxaliplatin-induced neurotoxicity remains unclear, the present study investigated the potential of axonal excitability techniques in identifying pathophysiologic mechanisms and early markers of nerve dysfunction. PATIENTS AND METHODS Measures of sensory axonal excitability were recorded before and after infusion over 88 treatment cycles in 25 patients with colorectal cancer, who received a total oxaliplatin dose of 766 +/- 56 mg/m(2). Neurologic assessment, clinical rating scales, and routine nerve conduction studies were performed. RESULTS By completion of treatment, 16% of patients had developed severe (grade 3) neurotoxicity, and oxaliplatin dose reduction or cessation as a result of neurotoxicity was required in 40% of patients. Changes in axonal excitability occurred after infusion and could be explained on the basis of alterations in axonal membrane sodium (Na+) channel function (refractoriness: 7.6% +/- 1.7% before infusion v 4.5% +/- 1.4% after infusion; P = .03; superexcitability: -22.8% +/- 0.8% before infusion v -20.1% +/- 1.1% after infusion; P = .0002). Changes became less pronounced in later treatment cycles, suggesting that chronic nerve dysfunction and sensory loss masked acute effects at higher cumulative doses. Importantly, patients who demonstrated reductions in superexcitability in early treatment were subsequently more likely to develop moderate to severe neurotoxicity. The findings suggest that the degree of acute nerve dysfunction may relate to the development of chronic neurotoxicity. CONCLUSION Sensory axonal excitability techniques may facilitate identification of Na+ channel dysfunction in oxaliplatin-induced neurotoxicity and thereby provide a method to identify patients at risk for neurotoxicity to target those most likely to benefit from future neuroprotective strategies.

Abstract
The purpose of this study is to characterize the expression of HuR in colorectal carcinoma and determine its correlation with clinical outcome. Differential expression of HuR has been suggested to be of prognostic significance in carcinomas of the ovaries, stomach, and breast. HuR regulates the expression of a variety of proteins critical to carcinogenesis via the pathways of cell-cycle progress, invasion, and metastasis. Increasing evidence suggests that angiogenic pathways are involved. A tissue microarray consisting of tumors from 560 patients with colorectal adenocarcinoma was analyzed for HuR protein expression using a quantitative, automated immunofluorescent microscopy system (AQUA). Clinical data corresponding to each examined specimen collected through an institutional review board (IRB)-approved protocol were analyzed using chi-squared test, Cox regression, and Kaplan-Meier analysis. Median follow-up was 54 months. Along with tumor stage and overall tumor-node-metastasis (TNM) stage, HuR expression was found to be an independent predictor of survival. In patients in the highest quartile of total HuR expression, survival was 22.8 months less than those in the lower quartiles (40.6 versus 63.4 months, p = 0.04). Furthermore, HuR levels correlate positively with expression of vascular endothelial growth factor (VEGF) and CD31, a marker for vascular endothelium. We conclude that expression of high levels of HuR correlates with features of advanced disease and portends poorer survival in patients with colorectal adenocarcinoma. These results further suggest that HuR exerts its tumorigenic effects through VEGF-mediated angiogenesis and may be a novel therapeutic target in colorectal cancer.

Abstract
BACKGROUND Patients older than 75 years of age are usually excluded from metastatic colorectal cancer randomized studies. The OPTIMOX1 study evaluated FOLFOX7, a simplified (s) leucovorin (LV) and 5-fluorouracil (5FU) regimen (sLV5FU2) with high-dose oxaliplatin, in a new oxaliplatin stop-and-go strategy. An exploratory cohort of patients aged 76 to 80 years was included in the study. METHODS In all, 620 previously untreated patients were randomized between FOLFOX4 until progression (arm A), or FOLFOX7 for 6 cycles, maintenance without oxaliplatin for 12 cycles, and reintroduction of FOLFOX7 (arm B). RESULTS A total of 37 patients aged 76 to 80 years were included, 20 in arm A and 17 in arm B. The overall response rate (ORR) was 59.4%, comparable to younger patients (59%). Median progression-free survival (PFS) was 9.0 months and median overall survival (OS) was 20.7 months. These results did not differ from that in younger patients < or =75 years in the OPTIMOX1 study with PFS 9.0 months (P = .63) and OS 20.2 months (P = .57). They experienced slightly more grade 3 of 4 toxicity than younger patients: 65% versus 48% (P = .06), mainly with more neutropenia (41% vs 24%, P = .03) and neurotoxicity (22% vs 11%, P = .06). Tolerability, however, was manageable and no toxic death occurred in this elderly population. CONCLUSIONS The efficacy of FOLFOX-based treatment was maintained in patients >75 years with both FOLFOX regimens. The oxaliplatin stop-and-go management strategy performed well in this population.

Abstract
BACKGROUND The past years' therapy for colorectal cancer has evolved rapidly with the introduction of novel cytotoxic agents such as irinotecan, capecitabine and oxaliplatin. Further advances have been achieved with the integration of targeted agents such as bevacizumab, cetuximab and recently, panitumumab. As a result, third-line treatment is now a necessary step in the optimal treatment of patients with metastatic colorectal cancer (MCRC). MATERIALS AND METHODS We conducted a literature review of English language publications on third-line therapy for MCRC from January 2000 to April 2007. Data on median overall survival (mOS), median time to progression (mTTP) and response rate were recorded. RESULTS We found 27 articles and 22 abstracts to fulfil the criteria. Patients who received regimens containing oxaliplatin and infusional 5-fluorouracil (5-FU) demonstrated mTTP up to 7 months and a mOS of 16 months. With irinotecan and 5-FU, mOS around 8 months were reported and with cetuximab combined with irinotecan, the highest mOS was 9.8 months. CONCLUSION Third-line therapy in advanced colorectal cancer may improve mOS for patients with MCRC. Therefore, randomized studies should be conducted in the future.

Abstract
BACKGROUND Oxaliplatin stop and go in combination with leucovorin and 5-fluorouracil has been successfully used in a previous study (OPTIMOX1) in metastatic colorectal cancer (MCR). Celecoxib is an anti-cyclooxygenase-2 drug with anti-neoplastic properties. In the present study, celecoxib was evaluated in combination with FOLFOX7 regimen and as a single agent in maintenance therapy. PATIENTS AND METHODS This phase II study examined for previously untreated MCR patients the stop-and-go procedure [six cycles of folinic acid, 5FU and oxaliplatin (FOLFOX7) followed by chemotherapy-free intervals (CFIs) and reintroduction at progression] with continuous administration of celecoxib (800 mg/day). RESULTS Forty-four patients were included, 42 eligible: performance status (%) 0/1/2=45/40/15, median age 60 (31-76) years. Response rate (RR) was 43% (95% CI 28%-58%). Median progression-free survival (PFS) was 6 months; median overall survival was 15.8 months. Grade 3/4 toxicity criteria were neurotoxicity 9.5%, thrombocytopenia 21.4%, neutropenia 7.1%, diarrhea 7.1%, nausea 4.8% and vomiting 2.4%. Median CFI 1 (n=27) duration was 3.9 months (range 2-39 months). CONCLUSION With an acceptable safety profile, celecoxib combined with FOLFOX7 achieved RR and PFS in the lower range of that obtained with FOLFOX7 alone. These results indicate the lack of synergy between FOLFOX7 and celecoxib. PFS of 6 months appears lower than PFS obtained in OPTIMOX1 study with simplified LV5FU2 in maintenance therapy.

Abstract
AIM: To evaluate the short-time efficacy, side effects, survival of combined chemotherapy of oxaliplatin or hydroxycamptothecine plus 5-fluorouracil and leucovorin for advanced colorectal cancer.
METHODS: Sixty patients with advanced colorectal cancer confirmed by pathology were included in this study. The patients in group A (n = 40) received oxaliplatin plus 5-fluorouracil and leucovorin, and those in group B (n = 20) were treated with hydroxycamptothecine plus 5-fluorouracil and leucovorin. Both regimens had 21-day cycle, i.e., the treatment was repeated once every 3 wk and the side effects were evaluated. The efficacy was estimated two or three cycles after chemotherapy.
RESULTS: The efficacy rates were 30.0% (12/40) and 25.0% (5/20) in group A and B, respectively, and there was no significant difference between them (χ2 = 0.531, P = 0.811). The 1-year survival rates (34.09% vs 38.55%, u = 0.3275, P > 0.05), median progression-free survival time (6.4 mo vs 7.3 mo, u = 1.5088, P > 0.05), and median overall survival time (10.2 mo vs 10.8 mo, u= 0.3487, P > 0.05) were not markedly different between group A and B, neither. The major side effects of grade Ⅲ and Ⅳ in both groups were myelosuppression and gastrointestinal reactions, and the incidence rate of diarrhea was significantly higher in group B than that in group A (χ2 = 7.876, P = 0.044).
CONCLUSION: The efficacy is almost equal between combined chemotherapy of oxaliplatin or hydroxycamptothecine plus 5-fluorouracil and leucovorin for advanced colorectal cancer. Peripheral neuropathy appears more as the former is used, while diarrhea has a higher frequency as the latter is used.

Abstract
BACKGROUND Patients with metastatic colorectal carcinoma (MCC) to the liver receive conflicting management recommendations because of the lack of prospective randomized controlled trials (RCTs) clarifying the optimal management in this disease. The objective of the current study was to evaluate the reporting of prognostic factors in MCC from chemotherapy and surgery trials and evaluate the ability to compare these results across treatments. METHODS RCTs and retrospective series of greater than 75 MCC patients published between 1980-2004 were reviewed to identify 10 critical prognostic elements of overall survival reported in both types of journals. RESULTS A review 92 RCTs and 116 retrospective reports with 64,898 patients analyzed found 7 (3%) reporting all prognostic factors, with both studies demonstrating no difference in the success of reporting criteria met. The only criterion that was universally reported among both chemotherapy and surgery trials was the mortality rates of the study. All remaining prognostic factors in the evaluation of overall survival were significantly different between both chemotherapy and surgical studies. Considerable variation was observed in the disease-free interval, number of hepatic metastases, size of hepatic metastases, and performance status, and were significantly different among some of the most significant factors for patients evaluating treatment: complication reporting, surgical margin evaluation, and overall response rate. CONCLUSIONS The reporting of results in MCC in chemotherapy trials and surgical reports is limited to general outcomes, with a paucity of prognostic factors, which hinders any ability to compare results across treatments. A mandatory reporting criteria of all metastatic colorectal trials is imperative to optimally manage these patients in both academic and community centers.

Abstract
Peripheral neuropathy induced by cancer chemotherapy represents a large unmet need for patients due to the absence of treatment that can prevent or mitigate this common clinical problem. Chemotherapy-induced peripheral neuropathy (CIPN) diagnosis and management is further compounded by the lack of reliable and standardized means to diagnose and monitor patients who are at risk for, or who are symptomatic from, this complication of treatment. The pathogenesis and pathophysiology of CIPN are not fully elucidated, but there is increasing evidence of damage or interference with tubulin function. The diagnosis of CIPN may present a diagnostic dilemma due to the large number of potential toxic etiologies and conditions, which may mimic some of the clinical features; the diagnosis must be approached with care in such patients. The incidence and severity of CIPN is commonly under-reported by physicians as compared with patients. The development of new and reliable methods for the assessment of CIPN as well as safe and effective treatments to prevent this complication of treatment would represent important medical advancements for cancer patients.
