to the tumor by the radiologist. During the surgery, the marker was clearly identified and the cutting line was determined to ensure a sufficient surgical margin. The tumor was laparoscopically resected as planned. The histopathologic diagnosis was adenocarcinoma, compatible with metastasis of coloncancer. The postoperative course was uneventful and the patient remained free of disease at 10 months after surgery. Conclusion: When resecting small tumors or tumors with an irregular margin, a marking (...) The Use of CT-Guided Marking for the Laparoscopic Resection of a Solitary Retroperitoneal Metastasis of ColonCancer Background: CT-guided marking technique is rarely used in abdominal or urologic surgery. We developed and performed a marking technique for a small tumor, undetectable by ultrasound, using CT guidance before laparoscopic resection of the tumor. Case Presentation: A 73-year-old woman with a history of breast cancer underwent right colectomy with D3 lymph node dissection

Colorectal sarcoma: more than a gastrointestinal stromal tumor Primary colorectal sarcomas have been defined as a rare and diverse group of mesenchymal cancers distinct from gastrointestinal stromal tumors (GISTs). Primary colorectal sarcomas have been recognized as a distinct entity from GISTs due to the dramatically worse prognosis these sarcomas carry. Also, primary colorectal sarcomas when compared to the more common colorectaladenocarcinoma, demonstrate more aggressive biology, present (...) at a younger age and carry worse outcomes. At this time, surgery remains the mainstay of treatment and adjuvant chemotherapy has an unclear role in treatment of primary colorectal sarcoma. This paper attempts to review the available data regarding primary colorectal sarcomas.
initially unresectable and previously untreated RAS and BRAF wild-type metastatic colorectalcancer patients are randomised to receive a standard treatment with mFOLFOX6 plus panitumumab or an experimental regimen with modified FOLFOXIRI (irinotecan 150 mg/m2, oxaliplatin 85 mg/m2, L-leucovorin 200 mg/m2, 5-fluoruracil 2400 mg/m2 48-hour continuous infusion) plus panitumumab up to 12 cycles, followed by panitumumab plus 5-fluorouracil and L-leucovorin until disease progression. The primary endpoint (...) TRIPLETE: a randomised phase III study of modified FOLFOXIRI plus panitumumab versus mFOLFOX6 plus panitumumab as initial therapy for patients with unresectable RAS and BRAF wild-type metastatic colorectalcancer FOLFOXIRI plus bevacizumab is considered a standard option in the upfront treatment of clinically selected patients with metastatic colorectalcancer irrespective of RAS and BRAF molecular status. The randomised MACBETH and VOLFI studies showed that a modified FOLFOXIRI regimen
Bowel Obstruction and Ventral Hernia After Laparoscopic Versus Open Surgery for Rectal Cancer in A Randomized Trial (COLOR II) The aim of this study was to evaluate the risk of bowel obstruction, incisional, and parastomal hernia following laparoscopic versus open surgery for rectal cancer.Laparoscopic surgery for rectal cancer has been adopted worldwide, after trials reported similar oncological outcomes compared with open surgery. Little is known about long-term morbidity, including bowel (...) in risk of bowel obstruction, incisional, or parastomal hernia following laparoscopic or open surgery for rectal cancer.Based on long-term morbidity outcomes, laparoscopic surgery for rectal cancer could be considered a routine technique as there are no differences with open surgery.
FOLFOX or CAPOX in Stage II to III ColonCancer: Efficacy Results of the Italian Three or Six Colon Adjuvant Trial Purpose Given the cumulative neurotoxicity associated with oxaliplatin, a shorter duration of adjuvant therapy, if equally efficacious, would be advantageous for patients and health-care systems. Methods The Three or Six Colon Adjuvant trial is an open-label, phase III, multicenter, noninferiority trial randomizing patients with high-risk stage II or stage III coloncancer (...) . Conclusion The Three or Six Colon Adjuvant trial failed to formally show noninferiority of 3 versus 6 months of treatment to the predefined margin of 20% relative increase. The results depended on the adjuvant regimen and risk. For CAPOX, 3 months were as good as 6 months; for FOLFOX, 6 months added extra benefit. Counter-intuitively, the low-risk patients benefitted more than the high-risk population from the 6-month duration. The choice of regimen and duration should depend on patient characteristics
Three Versus 6 Months of Oxaliplatin-Based Adjuvant Chemotherapy for Patients With Stage III ColonCancer: Disease-Free Survival Results From a Randomized, Open-Label, International Duration Evaluation of Adjuvant (IDEA) France, Phase III Trial Purpose Reduction of adjuvant treatment duration may decrease toxicities without loss of efficacy in stage III coloncancer. This could offer clear advantages to patients and health care providers. Methods In International Duration Evaluation of Adjuvant (...) Chemotherapy (IDEA) France, as part of the IDEA international collaboration, patient with coloncancer patients were randomly assigned to 3 and 6 months of modified FOLFOX6 (mFOLFOX6: infusional fluorouracil, leucovorin, and oxaliplatin) or capecitabine plus oxaliplatin (CAPOX) by physician choice. The primary end point was disease-free survival (DFS), and analyses were descriptive. Results A total of 2,010 eligible patients received either 3 or 6 months of chemotherapy (modified intention-to-treat

Effect of Fruquintinib vs Placebo on Overall Survival in Patients With Previously Treated Metastatic ColorectalCancer: The FRESCO Randomized Clinical Trial. Patients with metastatic colorectalcancer (CRC) have limited effective and tolerable treatment options.To evaluate the efficacy and safety of oral fruquintinib, a vascular endothelial growth factor receptor (VEGFR) inhibitor, as third-line or later therapy in patients with metastatic CRC.FRESCO (Fruquintinib Efficacy and Safety in 3+ Line (...) ColorectalCancer Patients) was a randomized, double-blind, placebo-controlled, multicenter (28 hospitals in China), phase 3 clinical trial. From December 2014 to May 2016, screening took place among 519 patients aged 18 to 75 years who had metastatic CRC that progressed after at least 2 lines of chemotherapy but had not received VEGFR inhibitor therapy; 416 met the eligibility criteria and were stratified by prior anti-VEGF therapy and K-ras status. The final date of follow-up was January 17, 2017
Postoperative chemotherapy with single-agent fluoropyrimidines after resection of colorectalcancer liver metastases: a meta-analysis of randomised trials Surgical resection is the only option of cure for patients with metastatic colorectalcancer. Risk of recurrence after metastasectomy is around 75%. Use of adjuvant chemotherapy after metastasectomy is controversial.To address whether adjuvant systemic therapy after colorectalcancer metastasectomy offers any survival benefit compared (...) no overall survival (OS) benefit with the use of postoperative single-agent fluoropyrimidines compared with surgery alone, even if a trend for benefit was observed (relative hazard (RH)=0.781, 95% CI 0.593 to 1.030, p=0.080). Significant disease-free survival benefit with the use of postoperative chemotherapy was observed (RH=0.645, 95% CI 0.509 to 0.818, p=0.001). No quality of life (QL) data were available. All trials showed accrual delay, two stopped and one recruiting after 10 years. Long follow-up

Phase Ib/II trial evaluating the safety, tolerability and immunological activity of durvalumab (MEDI4736) (anti-PD-L1) plus tremelimumab (anti-CTLA-4) combined with FOLFOX in patients with metastatic colorectalcancer 5-Fluorouracil plus irinotecan or oxaliplatin alone or in association with target therapy are standard first-line therapy for metastatic colorectalcancer (mCRC). Checkpoint inhibitors targeting PD-1/PD-L1 demonstrated efficacy on mCRC with microsatellite instability but remain (...) ineffective alone in microsatellite stable tumour. 5-Fluorouracil and oxaliplatin were known to present immunogenic properties. Durvalumab (D) is a human monoclonal antibody (mAb) that inhibits binding of programmed cell death ligand 1 (PD-L1) to its receptor. Tremelimumab (T) is a mAb directed against the cytotoxic T-lymphocyte-associated protein 4 (CTLA-4). This study is designed to evaluate whether the addition of PD-L1 and CTLA-4 inhibition to oxaliplatin, fluorouracil and leucovorin (FOLFOX
Validation of the Survival Benefits of Metformin in Middle Eastern Patients With Type II Diabetes Mellitus and ColorectalCancer Purpose Epidemiologic data from several populations suggest that metformin may decrease cancer risk and mortality in patients with colorectalcancer (CRC) and type II diabetes mellitus (DM). Although type II DM and CRC are major health problems in the Middle East, no investigations have been performed to test the effect metformin has on the outcome of patients (...) with type II DM and CRC who are also treated with metformin. Materials and Methods We retrospectively reviewed the medical records of 1,902 patients diagnosed with CRC at King Hussein Cancer Center between January 2004 and December 2012, and identified 349 patients (18%) with type II DM; we censored the data of 28 patients because their antidiabetic medications were unknown. We then categorized these 321 patients into two groups: 192 patients treated with metformin (group A) and 129 patients treated
Clonal evolution of colorectalcancer in a patient with serially resected metastases and liquid biopsies: a case report and discussion of the literature Metastatic colorectalcancer represents a striking example of clonal heterogeneity and tumour evolution, which generates acquired resistance to therapy. Once hard to perform, the study of clonal heterogeneity is now significantly aided by the use of liquid biopsies.We herein report a case of a patient with colorectalcancer and serial (...) development of multiple metastases which were all resected and genotyped. A rare point mutation was identified in the primary tumour (but not in any of the organ metastatic sites), as well as in the first and the last out of three consecutive liquid biopsies. The review of the literature offered some insight in the evolution of the patient's tumour and general directions on how to interpret liquid biopsy results.This patient case emphasises the need for large prospective studies designed to bridge liquid
Risk factors for late bowel and bladder toxicities in NRG Oncology prostate cancer trials of high-risk patients: A meta-analysis of physician-rated toxicities A meta-analysis of sociodemographic variables and their association with late (>180 days from start of radiation therapy[RT]) bowel, bladder, and clustered bowel and bladder toxicities was conducted in patients with high-risk (clinical stages T2c-T4b or Gleason score 8-10 or prostate-specific antigen level >20) prostate cancer.Three NRG (...) received prostate-only RT+HT had a lower risk of experiencing grade ≥2 bowel toxicities than those who received whole-pelvic RT+long-term (LT) HT (hazard ratio: 0.36; 95% confidence interval, 0.18-0.73; P = .0046 and hazard ratio: 0.43; 95% confidence interval, 0.23-0.80; P = .008, respectively). Patients who received whole-pelvic RT had similar chances of having grade ≥2 bowel or bladder toxicities no matter whether they received LT or short-term HT.Patients with high-risk prostate cancer who receive
Assessing Clinical Outcomes in ColorectalCancer with Assays for Invasive Circulating Tumor Cells Colorectalcarcinoma (CRC) is the second leading cause of cancer-related mortality. The goals of this study are to evaluate the association between levels of invasive circulating tumor cells (iCTCs) with CRC outcomes and to explore the molecular characteristics of iCTCs. Peripheral blood from 93 patients with Stage I⁻IV CRC was obtained and assessed for the detection and characterization of iCTCs (...) using a functional collagen-based adhesion matrix (CAM) invasion assay. Patients were followed and assessed for overall survival. Tumor cells isolated by CAM were characterized using cell culture and microarray analyses. Of 93 patients, 88 (95%) had detectable iCTCs, ranging over 0⁻470 iCTCs/mL. Patients with Stage I⁻IV disease exhibited median counts of 0.0 iCTCs/mL (n = 6), 13.0 iCTCs/mL (n = 12), 41.0 iCTCs/mL (n = 12), and 133.0 iCTCs/mL (n = 58), respectively (p < 0.001).
