Abstract
Sensory neuropathy is a dose-limiting side effect of oxaliplatin-based cancer treatment. This study investigated the antinociceptive effect of amifostine and its potential neuroprotective mechanisms on the oxaliplatin-related peripheral sensory neuropathy in mice. Oxaliplatin (1 mg/kg) was injected intravenously in Swiss albino male mice twice a week (total of nine injections), while amifostine (1, 5, 25, 50, and 100 mg/kg) was administered subcutaneously 30 min before oxaliplatin. Mechanical and thermal nociceptive tests were performed once a week for 49 days. Additionally, c-Fos, nitrotyrosine, and activating transcription factor 3 (ATF3) immunoexpressions were assessed in the dorsal root ganglia. In all doses, amifostine prevented the development of mechanical hyperalgesia and thermal allodynia induced by oxaliplatin (P<0.05). Amifostine at the dose of 25 mg/kg provided the best protection (P<0.05). Moreover, amifostine protected against neuronal hyperactivation, nitrosative stress, and neuronal damage in the dorsal root ganglia, detected by the reduced expression of c-Fos, nitrotyrosine, and ATF3 (P<0.05 vs the oxaliplatin-treated group). In conclusion, amifostine reduced the nociception induced by oxaliplatin in mice, suggesting the possible use of amifostine for the management of oxaliplatin-induced peripheral sensory neuropathy.

Abstract
There have been remarkable advances in the treatment of metastatic colorectal cancer over the past 20 years, chiefly achieved by development of new active drugs and establishment of effective systemic therapy regimens. Multidisciplinary care of resectable liver disease with use of perioperative systemic therapy and superior liver resection has resulted in prolonged survival of select patients. Median overall survival has significantly improved with the modern multiagent regimens. This article reviews recent high-quality randomized clinical trials that were conducted to address optimal treatment of advanced and metastatic colorectal carcinoma, mainly focused on initially inoperable metastatic disease.

Abstract
Even with all improvements in both diagnostic and therapeutic techniques, lung cancer remains as the most lethal and prevalent cancer in the world. Therefore, new therapeutic drugs and new strategies of drug combination are necessary to provide treatments that are more efficient. Currently, standard therapy regimen for lung cancer includes platinum drugs, such as cisplatin, oxaliplatin, and carboplatin. Besides of the better toxicity profile of oxaliplatin when compared with cisplatin, peripheral neuropathy remains as a limitation of oxaliplatin dose. This study presents LabMol-12, a new pyridinyl carboxamide derivative with antileishmanial and antichagasic activity, as a new hit for lung cancer treatment, which induces apoptosis dependent of caspases in NCI-H1299 lung cancer cells both in monolayer and 3D culture. Moreover, LabMol-12 allows a reduction of oxaliplatin dose when they are combined, thereby, it is a relevant strategy for reducing the side effects of oxaliplatin with the same response. Molecular modeling studies corroborated the biological findings and suggested that the combined therapy can provide a better therapeutically profile effects against NSCLC. All these findings support the fact that the combination of oxaliplatin and LabMol-12 is a promising drug combination for lung cancer.

Abstract
The treatment of colorectal cancer has evolved dramatically in recent years with the availability of new chemotherapeutic agents and inhibitors of the vascular endothelial growth factor- and epidermal growth factor-signaling pathways. The incremental benefit of each individual line of therapy for advanced disease is relatively small. Advances in our ability to select patients should improve the cost-effectiveness of our treatment strategies (avoiding unnecessary toxicity in the patients who are unlikely to benefit and accepting the potential for adverse events in the patients who stand to benefit the most from a given regimen).

Abstract
Rectal cancer, along with colon cancer, is the second leading cause of cancer-related deaths in the U.S. Up to a quarter of patients have metastatic disease at diagnosis and 40% will develop metastatic disease. The past 10 years have been extremely exciting in the treatment of both locally advanced and metastatic rectal cancer (mRC). With the advent of neoadjuvant chemoradiation, increased numbers of patients with locally advanced rectal cancer (LARC) are surviving longer and some are seeing their tumors shrink to sizes that allow for resection. The advent of biologics and monoclonal antibodies has propelled the treatment of mRC further than many could have hoped. Combined with regimens such as FOLFOX or FOLFIRI, median survival rates have been increased to an average of 23 months. However, the combinations of chemotherapy regimens seem endless for rectal cancer. We will review the major chemotherapies available for locally advanced and mRC as well as regimens currently under investigation such as FOLFOXIRI. We will also review vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) inhibitors as single agents and in combination with traditional chemotherapy regimens.

Abstract
SUMMARY Fluoropyrimidines (5-fluorouracil, capecitabine, S-1, Uftoral® [UFT; Merck, Germany]) and their derivatives are effective in management of colorectal cancer. DPD deficiency is not routinely tested and is usually diagnosed after a patient has severe/grade IV toxicity secondary to the use of 5-fluorouracil or capecitabine. Once DPD deficiency is diagnosed, there are sparse data on the use of UFT or raltitrexed and there are no comparable outcome data with well-known regimens like infusional 5-fluorouracil, leucovorin oxaliplatin (FOLFOX) and infusional 5-fluorouracil, leucovorin, irinotecan (FOLFIRI). Here we report the first case series from India of DPD deficiency and the use of UFT.

Abstract
BACKGROUND The administration of adjuvant chemotherapy for rectal cancer patients with ypN0 is controversial. The purposes of this study were to evaluate the role of adjuvant chemotherapy in ypN0 patients and to optimize its use for these patients. METHODS We performed a retrospective study of 160 rectal cancer patients who had the final pathology of ypN0 between March 2003 and November 2010. Overall survival (OS), disease-free survival (DFS), local recurrence-free survival (LRFS), and distant metastasis-free survival (DMFS) were compared between patients who did and did not receive adjuvant chemotherapy. Multivariate analysis was performed to explore clinical factors significantly associated with DFS, LRFS, and DMFS. RESULTS For ypT0-2N0 patients, the 5-year OS, DFS, LRFS, and DMFS were similar between patients who did and did not receive adjuvant chemotherapy (P > 0.05). For patients with ypT3-4N0, those who were given adjuvant chemotherapy exhibited a higher 5-year OS than those who were not (P = 0.026), with also an extended 5-year DFS (P = 0.050). Further analysis indicated that adjuvant chemotherapy could decrease the rates of distant metastases for ypT3-4N0 patients with no impact on local control. In multivariable analysis, both the final pathological stage and adjuvant chemotherapy were independent predictors of DMFS for the whole group. When stratified by pathological stage, adjuvant chemotherapy was still significantly associated with DMFS in the ypT3-4 stratum. CONCLUSIONS Adjuvant chemotherapy may not improve survival for ypT0-2N0 patients. However, it may be clinically meaningful for ypT3-4N0 patients by decreasing rates of distant metastases. Further randomized controlled clinical trials are needed to address this problem.

Abstract
PURPOSE To evaluate progression-free survival (PFS) as a potential surrogate endpoint (SEP) for overall survival (OS) in metastatic colorectal cancer (mCRC) with a focus on applicability to trials containing targeted therapy with anti-VEGF- or anti-EGF receptor (EGFR)-directed monoclonal antibodies. EXPERIMENTAL DESIGN A systematic literature search of randomized trials of first-line chemotherapy for mCRC reported from January 2000 to January 2012 was conducted. Adjusted weighted linear regression was used to calculate correlations within PFS and OS (endpoints; R(EP)) and between treatment effects on PFS and on OS (treatment effects; R(TE)). RESULTS Fifty trials reflecting 22,736 patients met the inclusion criteria. Correlation between treatment effects on PFS and OS and between the endpoints PFS and OS was high across all studies (R(TE) = 0.87, R(EP) = 0.86). This was also observed in chemotherapy-only trials (R(TE) = 0.93, R(EP) = 0.81) but less so for trials containing monoclonal antibodies (R(TE) = 0.47; R(EP) = 0.52). Limiting the analysis to bevacizumab-based studies (11 trials, 3,310 patients) again yielded high correlations between treatment effects on PFS and on OS (R(TE) = 0.84), whereas correlation within PFS and OS was low (R(EP) = 0.45). In 7 trials (1,335 patients) investigating cetuximab- or panitumumab-based studies, contrasting correlations with very wide confidence intervals were observed (R(TE) = 0.28; R(EP) = 0.96). CONCLUSIONS PFS showed consistently high correlation with OS of an order that would justify its use as an SEP in chemotherapy regimens. For validation of surrogacy in anti-VEGF and anti-EGFR-directed therapies, further research and a larger set of trials is needed.

Alternative treatment options in colorectal cancer patients with 5-fluorouracil- or capecitabine-induced cardiotoxicity. Clin Colorectal Cancer 2012; 12:8-14.

Abstract
Most chemotherapy regimens in colorectal cancer treatment are 5-fluorouracil (5-FU)/leucovorin or capecitabine-based. Cardiotoxicity is a less common but potentially lethal complication of 5-FU or capecitabine treatment, and some physicians might be unfamiliar with treatment alternatives. Rechallenging should be avoided because it carries a high risk of recurrence of the cardiac symptoms and prophylactic treatment is not always protective. Possible alternative treatment options to be considered are to replace the oral capecitabine or intravenous 5-FU by a 5-FU bolus regimen, by uracil-tegafur or tegafur/gimeracil/oteracil, both oral fluoropyrimidines combining a 5-FU prodrug with a dihydropyrimidine dehydrogenase (DPD) inhibitor, or by raltitrexed, a thymidilate synthase inhibitor whose metabolism is independent of DPD. Patients with advanced colorectal cancer and fluoropyrimidine-induced cardiotoxicity can be treated with other non-fluoropyrimidine related chemotherapy, either as a single agent, combined, or in combination with biological agents. In this report we discuss the different alternative treatment options.

Abstract
OBJECTIVE The objective of this study was to evaluate the safety of using tegafur-uracil (UFT) in colorectal cancer patients with partial dihydropyrimidine dehydrogenase (DPD) deficiency. PATIENTS AND METHODS The study included five colorectal cancer patients who presented with acute toxicity (grades 3 and 4) after being given the first cycle of chemotherapy using 5-fluorouracil. The DPD deficiency was confirmed by gene sequencing. After a full recovery from all side effects, we changed the regimen to UFT (300 mg/m(2)/day) associated with leucovorin (90 mg/day) for 21 days, with an empirical dose reduction of at least 10% in the first cycle. RESULTS We prospectively analysed 22 UFT cycles in 5 patients. We did not observe any episodes of grade 3 or 4 toxicity. The predominant toxicities were of grades 1 and 2 (nausea, vomiting and diarrhoea). CONCLUSION Here, we demonstrate a complete absence of severe toxicity in all patients and cycles analysed. We believe that UFT is a safe alternative for the treatment of patients with partial DPD deficiency.

Abstract
BACKGROUND Neoadjuvant chemoradiation followed by surgery and adjuvant chemotherapy is typically recommended for patients with locally advanced rectal cancer. Patients with pathologically node-negative tumors have an improved prognosis, but recurrence patterns and independent prognostic factors in these patients have been incompletely characterized. METHODS Using a retrospective cohort study design, we included all rectal cancer patients treated with neoadjuvant chemoradiation and curative surgery from 1993 through 2003, who had ypN0 tumors. We characterized recurrence rates and patterns in patients not treated with adjuvant chemotherapy. Secondarily, we compared them to patients who did receive adjuvant treatment and assessed for independent prognostic factors, using univariate and multivariable survival analyses. RESULTS Overall, 324 ypN0 patients (ypT0: n = 73; ypT1-2: n = 130; ypT3-4: n = 120) were followed for a median of 5.8 years. The risk of recurrence was associated with pathologic stage-2.7% ypT0, 12.3% ypT1-2, 24.2%ypT3-4. Five-year recurrence-free survival in patients who did not receive adjuvant treatment was 100% (ypT0), 84.4% (ypT1-2) and 75% (ypT3-4). There was no significant difference in 5-year recurrence-free survival between patients who did and did not receive adjuvant treatment. In multivariable analysis, pathologic stage was the factor most strongly associated with recurrence (hazard ratio 3.6 for ypT3-4 vs. ypT0-2, 95% confidence interval 1.9-6.7, P < 0.0001). CONCLUSIONS The recurrence rates for selected patients with ypT0-2N0 rectal cancer after neoadjuvant chemoradiation and total mesorectal excision are low. Although standard practice remains completion of planned postoperative adjuvant chemotherapy for all patients undergoing chemoradiation, these data suggest prospective trials may be warranted to measure the benefit of adjuvant chemotherapy in favorable subgroups, such as ypT0-2N0.

Abstract
AIM: To compare the efficacy of domestic and imported octreotide (Sandostatin) in the treatment of acute diarrhea associated with anti-tumor therapy.
METHODS: One hundred and thirty-eight patients with grade II or III diarrhea were enrolled into the study, of which 66 received Sandostatin treatment, and 72 were given domestic octreotide (100 µg, tid). Therapeutic efficacy was evaluated after a 3-day treatment.
RESULTS: No significant difference was noted in the complete remission rate of diarrhea between patients treated with Sandostatin and domestic octreotide (75.8% vs 79.2%, P > 0.05). The doses of domestic octreotide used on days 2 and 3 were significantly higher than those of Sandostatin (both P < 0.05). The cost-effectiveness value for Sandostatin was significantly higher than that for domestic octreotide (1148.7 vs 507.3, P < 0.05).
CONCLUSION: Domestic octreotide has equivalent efficacy and superior cost-effectiveness to Sandostatin in treating acute diarrhea associated with anti-tumor therapy. Increasing the dose of domestic octreotide is a reasonable choice in the management of grade III diarrhea.

Abstract
AIM: To investigate the correlation between uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1) gene polymorphisms and irinotecan-associated side effects and parameters of drug efficacy in patients with metastatic colorectal cancer (mCRC) receiving a low-dose weekly irinotecan chemotherapeutic regimen.
METHODS: Genotypes were retrospectively evaluated by gene scan analysis on the ABI 310 sequencer of the TATAA box in the promoter region of the UGT1A1 gene in blood samples from 105 patients who had received 1st line irinotecan-based chemotherapy for mCRC.
RESULTS: The distribution of the genotypes was as follows: wild type genotype (WT) (6/6) 39.0%, heterozygous genotype (6/7) 49.5%, and homozygous genotype (7/7) 9.5%. The overall response rate (OR) was similar between patients carrying the (6/7, 7/7) or the WT genotype (6/6) (44.3% vs 43.2%, P = 0.75). Neither time to progression [(TTP) 8.1 vs 8.2 mo, P = 0.97] nor overall survival [(OS) 21.2 vs 18.9 mo, P = 0.73] differed significantly in patients who carried the (6/6) when compared to the (6/7, 7/7) genotype. No significant differences in toxicity were observed: Grade 3 and 4 delayed diarrhoea [(6/7, 7/7) vs (6/6); 13.0% vs 6.2%, P = 0.08], treatment delays [(6/7, 7/7) vs (6/6); 25.1% vs 19.3%, P =0.24] or dose reductions [(6/7, 7/7) vs (6/6); 21.5% vs 27.2%, P = 0.07].
CONCLUSION: This analysis demonstrates the non-significant influence of the UGT1A1 gene polymorphism on efficacy and rate of irinotecan-associated toxicity in mCRC patients receiving low-dose irinotecan based chemotherapy.

Abstract
N9741 is a clinical trial in patients with metastatic colorectal cancer that was originally written in 1997 and completed patient accrual in 2004. One thousand seven hundred thirty-one patients were enrolled in the study. During the conduct of the trial, N9741 was repeatedly modified to adapt to toxicity findings, to add evaluation of oxaliplatin to what was originally a trial examining various schedules of irinotecan-based therapy, and to ask evolving questions. The trial led to a new U.S. Food and Drug Administration indication for 5-fluorouracil, leucovorin, and oxaliplatin as indicated for the treatment of previously untreated patients with metastatic colorectal cancer and helped to change the standard of care for the disease in the U.S. and worldwide. The data from the trial have been used to study multiple regimens, pharmacogenetics, and quality of life issues, to correlate plasma protein levels with outcomes, to inform trial methodology, and to perform economic analyses. To date nearly 30 papers and an even larger number of abstracts have been based upon data arising from the study. The history of the trial and the major findings are summarized in this review.

Abstract
BACKGROUND The Bevacizumab Regimens' Investigation of Treatment Effects (BRiTE) study is a prospective, observational cohort study designed to elucidate safety and effectiveness outcomes associated with bevacizumab combined with chemotherapy as used in clinical practice for first-line treatment of metastatic colorectal cancer (mCRC). PATIENTS AND METHODS Baseline characteristics, prespecified bevacizumab-related adverse events, and effectiveness data were collected from 1,953 mCRC patients who were receiving first-line treatment including bevacizumab at 248 U.S. sites. RESULTS At database lock, the median follow-up was 20.1 months. At baseline, 46% of patients were aged >or=65 years and 49% had an Eastern Cooperative Oncology Group performance status score >or=1. Fluorouracil, leucovorin, and oxaliplatin was the most common first-line chemotherapy regimen (56%). Overall rates of bevacizumab-related adverse events in the BRiTE study, such as gastrointestinal perforation (1.9%), arterial thromboembolic events (2%), grade 3-4 bleeding (2.2%), and de novo hypertension requiring medication (22%), were consistent with those reported in randomized clinical trials (RCTs) of bevacizumab in first-line mCRC treatment. The median progression-free survival (PFS) and overall survival (OS) times were 9.9 (95% confidence interval [CI], 9.5-10.3) months and 22.9 (95% CI, 21.9-24.4) months, respectively. CONCLUSION The median PFS and OS durations and safety profile of bevacizumab in the BRiTE study were similar to those in RCTs of bevacizumab plus chemotherapy in first-line mCRC patients. The observations from the BRiTE study complement and expand upon RCT data, providing clinical information in a large cohort of bevacizumab-treated patients and subgroups such as the elderly.

Pilot study of irinotecan/oxalipltin (IROX) combination chemotherapy for patients with gemcitabine- and 5-fluorouracil- refractory pancreatic cancer. Invest New Drugs 2009; 28:343-9. [PMID: 19444385 DOI: 10.1007/s10637-009-9265-1] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2009] [Accepted: 05/04/2009] [Indexed: 12/11/2022]
Abstract
BACKGROUND Gemcitabine- and 5-fluorouracil (5-FU)- based chemotherapy is a commonly used adjuvant or palliative treatment for patients with pancreatic cancer. However, a standard chemotherapy regimen has yet to be developed for patients refractory to gemcitabine and 5-FU treatment. We attempted to evaluate the efficacy and safety of a combination of irinotecan and oxaliplatin (IROX) as a salvage treatment for patients with gemcitabine- and 5-FU- refractory pancreatic cancer. PATIENTS AND METHODS Patients with advanced pancreatic cancer who were refractory to prior gemcitabine- and 5-FU- based chemotherapy were enrolled in this study. IROX chemotherapy was administered as follows: Irinotecan, 150 mg/m(2) on day 1; and oxaliplatin, 85 mg/m(2) on day 1 over 90 min every 2 weeks. RESULT From Mar. 2006 to Dec. 2008, a total of 14 patients were administered 50 cycles of chemotherapy. The male-to-female ratio of the patient group was 11:3. These patients ranged in age from 48 to 73 years (median 65.5 years old). 3 patients (21.4%) evidenced partial responses. four patients (28.6%) exhibited stable disease. The median time to progression and overall survival time were 1.4 (95% CI: 1.2-1.6) months and 4.1 (95% CI: 2.0-6.2) months, respectively. Major hematologic toxicities included grade 1-2 anemia (88%), neutropenia (36%), thrombocytopenia (30%), and grade 3-4 neutropenia (10%). The most frequently detected non-hematological toxicities were grade 3 diarrheas (14%). CONCLUSION The IROX regimen appears to constitute a feasible and tolerable salvage therapy in patients with advanced pancreatic cancer who have been previously treated with gemcitabine- and 5-FU-based chemotherapy.

Abstract
The median age at diagnosis of colorectal cancer is during the seventh decade, and the incidence of the disease increases continuously with age. However, as the age increases, the possibilities of receiving adequate cancer treatment diminish and the mortality rises. So, there is a huge need for defined treatment strategies in elderly patients with colorectal carcinoma. The geriatric population is a very heterogeneous group where patients with an excellent health status coexist with the patients with both co-morbidities and functional dependency. Therefore, it is necessary to personalize each treatment according to the degree of vulnerability of the elderly patients. It is essential to set up a multidimensional geriatric assessment in order to consider not only the stage of the disease, but also all the factors that may influence the survival and interfere with the treatment. The aim of this review is to discuss the potential benefits and issues of chemotherapy in the elderly patients affected with colorectal cancer.

Abstract
Cisplatin, carboplatin, and oxaliplatin anticancer drugs are commonly used to treat lung, colorectal, ovarian, breast, head and neck, and genitourinary cancers. However, the efficacy of platinum-based drugs is often compromised because of the substantial risk for severe toxicities, including neurotoxicity. Neurotoxicity can result in both acute and chronic debilitation. Moreover, colorectal cancer patients treated with oxaliplatin discontinue therapy more often because of peripheral neuropathy than tumor progression, potentially compromising patient benefit. Numerous methods to prevent neurotoxicity have thus far proven unsuccessful. To circumvent this life-altering side effect while taking advantage of the antitumor activities of the platinum agents, efforts to identify mechanism-based biomarkers are under way. In this review, we detail findings from the current literature for genetic markers associated with neurotoxicity induced by single-agent and combination platinum chemotherapy. These data have the potential for broad clinical implications if mechanistic associations lead to the development of toxicity modulators to minimize the noxious sequelae of platinum chemotherapy.
