BACKGROUND: The addition of oxaliplatin to adjuvant treatment regimens for colorectal cancer has been shown to improve overall survival at the expense of increased toxicity. The incidence and severity of toxicity might be greater among older patients who might also derive less benefit from oxaliplatin. We evaluated the association between adjuvant oxaliplatin-based chemotherapy and neurotoxicity outcomes in an elderly cohort of patients. PATIENTS AND METHODS: A population-based cohort of patients aged > 65 years with stage II and III colorectal cancer treated with adjuvant therapy in Ontario, Canada was identified using the Ontario Cancer Registry...

BACKGROUND: Little is known about anorectal function and quality of life after chemoradiation followed by local excision, which is an alternative to total mesorectal excision for selected patients with early rectal cancer. OBJECTIVE: The purpose of this study was to prospectively assess anorectal function and health-related quality of life of patients with T2N0 rectal cancer who were treated with an alternative approach. DESIGN: This was a prospective, phase II trial...

BACKGROUND: Although chemotherapy represents a predominant anti-cancer therapeutic modality, drug treatment efficacy is often limited due to the development of resistant tumor cells. The pregnane X receptor (PXR) affects chemotherapeutic effects by regulating targets involved in drug metabolism and transportation, but the regulatory mechanism is poorly understood. METHODS: Oxaliplatin (L-OHP) content in tumor cells was analyzed by mass cytometry. The roles of PXR on cancer cell proliferation, apoptosis and tumor growth with L-OHP-treated were investigated by MTS, colony formation, flow cytometry and xenograft tumor assays...

BACKGROUND: In Japan, oxaliplatin (OXA)/5-fluorouracil (5-FU)/leucovorin (LV)-the mFOLFOX6 regimen-is the most frequently used first-line chemotherapy backbone for metastatic colorectal cancer. However, peripheral nerve disorders caused by OXA during mFOLFOX6 therapy can decrease patients' quality of life. OXA can be safely discontinued from a FOLFOX regimen after 6 cycles during first-line therapy. Also, for patients who discontinue OXA without having experienced peripheral nerve disorders, reintroducing OXA in the later stages of treatment could remain an option...

BACKGROUND: Colorectal cancer (CRC) is a heterogeneous disease in terms of molecular carcinogenic pathways. Based on recent findings regarding the multiple serrated neoplasia pathway, we revised an eight-marker panel for a new CIMP classification system. METHODS: 1370 patients who received surgical resection for CRCs were classified into three CIMP subtypes (CIMP-N: 0-4 methylated markers, CIMP-P1: 5-6 methylated markers and CIMP-P2: 7-8 methylated markers). Our findings were validated in a separate set of high-risk stage II or stage III CRCs receiving adjuvant fluoropyrimidine plus oxaliplatin (n=950)...

Colorectal cancer (CRC) is one the greatest contributors to cancer related mortality. Although 5 year survival rate for patients at the early stage of CRC (stages I and II) is above 60%, more than 50% of patients are diagnosed at or beyond stage III when distant metastasis has already occurred, in which case 5 year survival rate drops to 10%. Chemotherapeutic intervention coupled with surgery is the backbone of metastatic CRC treatment and the only means of enhanced survival. For decades following its discovery, an antimetabolite 5-fluorouracil (5-FU) was the only chemotherapeutic agent available to successfully improve 12 month survival in CRC patients...

BACKGROUND: For borderline resectable colorectal cancer liver metastases (CLM), systemic treatment can help to achieve R0 resection and reduce the risk of relapse. We assessed the role of perioperative triplet chemotherapy in combination with cetuximab in patients with RAS wild type high recurrence risk and/or borderline resectable CLM. PATIENTS AND METHODS: This was a monocenter, open-label phase II study. Borderline resectability was defined technically as tumor involvement of >1 hepatic vein, or >4 hepatic segments, need for 2-stage hepatectomy or radiofrequency ablation, and/or biologically (high risk): ≥4 metastatic nodules, or synchronous metastases...

BACKGROUND: Six months of oxaliplatin-based chemotherapy is the standard adjuvant chemotherapy for completely resected stage III colorectal cancer (CRC). Also, patients with stage II CRC who are considered to be at high risk of disease recurrence often receive the same adjuvant chemotherapy treatment. We prospectively investigated the extent and degree of neuropathy suffered by stage III and high-risk stage II resectable CRC patients who underwent sequential approach involving 3 months of an oxaliplatin-based regimen followed by 3 months of capecitabine...

BACKGROUND: Elderly patients with primary colorectal cancer (CRC) are less frequently treated with adjuvant chemotherapy than younger patients due to concerns regarding toxicity and efficiency. We investigated how age, performance status (PS) and comorbidity influence treatment outcomes. PATIENTS AND METHODS: A retrospective single-centre study of 529 patients with stages II-III CRC treated with adjuvant chemotherapy (5-fluorouracil/capecitabine+/÷oxaliplatin) from 2001 to 2011 at Herlev Hospital, Denmark...

In 2015, ramucirumab and TAS-102 became the 10th and 11th drugs approved by the Food and Drug administration for the treatment of patients with colorectal cancer, not counting leucovorin, and yet only 3 agents, 5-fluorouracil, capecitabine, and oxaliplatin, have proven benefit in adjuvant treatment. In fact, there have been no additions (and 1 subtraction levamisole) to our arsenal of therapies for patients with stages II and III colon cancer for more than a decade. How did we get here? Are we stuck? And how do we move forward?...

IMPORTANCE: Oxaliplatin added to fluorouracil plus leucovorin therapy for patients with colon cancer has been shown to provide significant but modest absolute benefit for disease-free survival. However, acute and chronic neurotoxic effects from this regimen underscore the need for markers that predict oxaliplatin benefit. OBJECTIVE: To test our hypothesis that molecular subtypes of colon cancer would be associated with differential prognosis and benefit from oxaliplatin added to fluorouracil plus leucovorin therapy...

of Background Data The effectiveness of adjuvant chemotherapy in patients with stage II/III colorectal cancer has been confirmed in various studies. However, no adjuvant chemotherapy for colorectal liver metastasis (CLM) classified to stage IV has been established. Objectives We conducted a phase 1 study of S-1 and oxaliplatin to determine the recommended dose (RD) in patients with CLM as adjuvant therapy in two institutes. Methods S-1 and oxaliplatin were administered from day 1 to day 14 of a 3-week cycle as a 2-h infusion every 3 weeks, respectively...

BACKGROUND: Low methylation status of LINE-1 in tumors is associated with poor survival in patients with colon cancer. Eastern Cooperative Oncology Group performance status (ECOG-PS) is a method to assess the functional status of a patient. We retrospectively evaluated the relationship between ECOG-PS and LINE-1 methylation in colorectal cancers (CRCs) and their prognostic impact in CRC or colon cancer patients receiving adjuvant 5-fluorouracil/leucovorin/oxaliplatin (FOLFOX). RESULTS: LINE-1 methylation and microsatellite instability were analyzed in stage III or high-risk stage II CRCs (n = 336)...

PURPOSE: The purpose of this study was to explore the experiences of oxaliplatin-induced neurotoxic side effects among patients with colorectal cancer (CRC) and how these side effects influenced their daily lives over time. METHODS: To assess neurotoxic side effects, ten patients were repeatedly interviewed. The patients were recruited from two hospitals in south of Sweden, had stage II-III CRC, and had been treated with adjuvant oxaliplatin postoperatively, from November 2013 to October 2015...

Oxaliplatin is frequently used as part of a chemotherapeutic regimen with 5-fluorouracil in the treatment of colorectal cancer (CRC). The cellular availability of oxaliplatin is dependent on metabolic and transporter enzymes. Variants in genes encoding these enzymes may cause variation in response to oxaliplatin and could be potential predictive markers. Therefore, we used a two-step procedure to comprehensively investigate 1,444 single nucleotide polymorphisms (SNPs) from these pathways for their potential as predictive markers for oxaliplatin treatment, using 623 stage II-IV CRC patients (of whom 201 patients received oxaliplatin) from a German prospective patient cohort treated with adjuvant or palliative chemotherapy...

BACKGROUND: The CpG island methylator phenotype (CIMP) is a promising biomarker for irinotecan/5-fluorouracil/leucovorin chemotherapy for stage III colon cancer. In the present study, we evaluated whether CIMP is a prognostic biomarker for standard-of-care oxaliplatin-based adjuvant therapy. MATERIALS AND METHODS: The HE6C/05 trial randomized 441 patients with stage II-III colorectal adenocarcinoma to adjuvant XELOX (capecitabine, oxaliplatin) or modified FOLFOX6 (5-fluorouracil, leucovorin, oxaliplatin)...

BACKGROUND: SLFN11 was reported to be a predictive marker for DNA damage drugs. The study was to investigate whether SLFN11 expression is related to sensitivity to adjuvant oxaliplatin-based treatment in colorectal cancer. METHODS: A tissue microarray, made with specimens from consecutive 261 patients who received oxaliplatin based adjuvant chemotherapy, was stained with anti-SLFN11 antibody. The staining was dichotomized as high or low expression. SLFN11 expression was correlated to clinicopathological factors, KRAS exon 2 mutation and survival...
