Time to Diagnosis and Treatment with Palliative Radiotherapy among Inuit Patients with Cancer from the Arctic Territory of Nunavut, Canada.

AIMS: The cancer burden among Circumpolar Inuit is high. Palliative radiotherapy is a mainstay treatment for controlling symptoms of advanced cancers, but Inuit are required to travel far distances to access this service. Access to palliative radiotherapy and time away from home communities have not been explored among this population. We sought to describe the time intervals from symptom onset to the start of palliative radiotherapy among Canadian Inuit patients treated at The Ottawa Hospital (TOH). MATERIALS AND METHODS: A retrospective review of Inuit patients from Nunavut treated with radiotherapy between 2005 and 2014 at TOH. RESULTS: Of a total of 152 radiotherapy patients, 88 (58%) were treated palliatively. Of these, 61 (70%) had stage IV disease at diagnosis and 63 (72%) had lung cancer. The median time from referral for specialist care to the patient's first flight to Ottawa was 4 days (range 0-97). The median length of treatment was 7 days (range 0-27), but patients spent a median of 64.5 days (range 14-633) in Ottawa. The median survival from the date of pathological diagnosis was 5.2 months. CONCLUSIONS: Most Inuit radiotherapy patients at TOH were treated palliatively. Patients were brought from Nunavut relatively quickly for specialist care, which is encouraging. However, patients spent over 2 months away from home, in the context of a median survival of less than 6 months. Opportunities for improvement include both provider and system-level changes, which may be applicable to other Circumpolar Inuit regions across Europe and North America.

Experts in radiation oncology, medical oncology, surgical oncology, and cancer genetics who are involved in the management of patients with gastrointestinal malignancies participated in presentations and discussion sessions for the purpose of developing the recommendations presented here. This consensus statement addresses multiple topics in the management of gastric, rectal, and colon cancer, including ■ identification and management of hereditary gastric and colorectal cancer (crc);■ palliative systemic therapy for metastatic gastric cancer;■ optimum duration of preoperative radiation in rectal cancer-that is, short- compared with long-course radiation;■ management options for peritoneal carcinomatosis in crc;■ implications of tumour location for treatment and prognosis in crc; and■ new molecular markers in crc.

Uptake and Effectiveness of FOLFIRINOX for Advanced Pancreatic Cancer: a Population-based Study.

AIMS: Although FOLFIRINOX is a standard treatment option for advanced pancreas cancer, there are few data describing utilisation and effectiveness in routine clinical practice. Here we report practice patterns and outcomes in the general population of Ontario, Canada. MATERIALS AND METHODS: Using the Ontario Cancer Registry and New Drug Funding Program, we identified all patients with pancreas cancer treated with palliative intent gemcitabine or FOLFIRINOX in Ontario during 2006-2014. FOLFIRINOX became available in Ontario's single-payer health system in November 2011. Gemcitabine cases were classified as pre-FOLFIRINOX era (2006-2010) or post-FOLFIRINOX era (2011-2014). Cases treated with perioperative chemotherapy were excluded. Comparisons of proportions between study groups were made using the chi-square test. Overall survival was measured from the date of chemotherapy initiation. RESULTS: During 2006-2014, 3826 patients in Ontario were treated with gemcitabine (n = 3042) or FOLFIRINOX (n = 784) chemotherapy for advanced pancreas cancer. Uptake of FOLFIRINOX increased from 41% (206/505) of treated cases in 2012 to 56% (274/486) of treated cases in 2014. The median overall survival of patients treated with gemcitabine was 5.0 months in 2006-2010 and 4.8 months in 2011-2014. The median overall survival of FOLFIRINOX patients treated in 2011-2014 was 8.2 months. CONCLUSION: The use of FOLFIRINOX in the general population has increased since 2011. Survival outcomes show a substantial efficacy-effectiveness gap between the pivotal Prodige 4/ACCORD 11 clinical trial and routine practice.

Real-life treatment of metastatic colorectal cancer with regorafenib: a single-centre review.

BACKGROUND: Various tyrosine kinase signalling pathways affect the development and progression of colorectal cancer (crc). In clinical trials, regorafenib has been associated with a survival benefit in metastatic crc (mcrc). We assessed the safety and efficacy of regorafenib in real-world patients. METHODS: In a retrospective review of patients with mcrc treated with regorafenib at our institution from 2013 to 2015, patient demographics, treatment, and survival data were collected. Progression-free survival (pfs) and overall survival (os) were estimated using the Kaplan-Meier method. RESULTS: In total, 48 patients were offered regorafenib, and 35 (73%) started treatment. Of the patients who started regorafenib, 57% were men. Median age in the cohort was 61 years, and all patients had a performance status in the range 0-2. Time from diagnosis of mcrc to regorafenib treatment was more than 18 months in 71% of patients. Starting dose was 160 mg in 54% of the patients, 120 mg in 40%, and 80 mg in 6%. Dose reductions occurred in 34% of the patients, and interruptions, in 29%. Best response was progressive disease (60%) and stable disease (17%); response in the rest of the patients was unknown. The most common adverse events on regorafenib (any grade) were fatigue (57%), hyperbilirubinemia (43%), thrombocytopenia (37%), anorexia (31%), and hypertension (31%). The most common grade 3 or 4 adverse events were fatigue (29%), hypophosphatemia (17%), weight loss (11%), and hyperbilirubinemia (9%). Common reasons for discontinuing regorafenib included progressive disease (51%) and toxicity (26%). In patients treated with regorafenib, pfs was 2.4 months (95% confidence interval: 1.8 to 3.3 months) and os was 5.6 months (95% confidence interval: 3.7 to 8.9 months). No factors were associated with survival in univariate or multivariate analysis. CONCLUSIONS: In a real-world setting, regorafenib is associated with survival similar to that reported in the randomized controlled trials, but at the expense of toxicity leading to discontinuation in many patients. Future studies of regorafenib should focus on identifying the patients most likely to benefit and on minimizing toxicity.

Systemic therapy in incurable gastroenteropancreatic neuroendocrine tumours: a clinical practice guideline.

PURPOSE: The purpose of the present review was to determine which antineoplastic systemic therapy is most effective in improving clinical outcomes for patients with incurable gastroenteropancreatic neuroendocrine tumours (nets). METHODS: A systematic search (2008-2016) of the literature in the medline and embase databases and the Cochrane Database of Systematic Reviews was conducted; abstracts from the American Society of Clinical Oncology, the American Society of Clinical Oncology Gastrointestinal Cancers Symposium, the European Society for Medical Oncology, the European Cancer Congress, the European Neuroendocrine Tumor Society, and the North American Neuroendocrine Tumor Society were reviewed. Draft recommendations were created, and a comprehensive review process was undertaken. Outcomes-including progression-free survival (pfs), overall survival, objective response rate, adverse events, and quality of life-were extracted from each of the studies. RESULTS: Eleven randomized controlled trials (rcts), sixteen nonrandomized prospective studies, and thirteen retrospective studies met the inclusion criteria. CONCLUSIONS: Patients with well-or moderately-differentiated pancreatic nets (pnets) should receive targeted therapy (that is, everolimus or sunitinib), and patients with non-pnets should be offered either targeted therapy (that is, everolimus) or somatostatin analogues (ssas-that is, octreotide long-acting release or lanreotide). Evidence from two phase iii trials demonstrated a significant pfs benefit for patients with pnets. For patients with non-pnets, the evidence comes from subgroup analyses of rcts, as well as from a planned interim analysis. Although the evidence has limitations, the rarity of the disease, coupled with the difficulty of conducting methodologically sound trials in the affected population, means that treatment decisions have to make use of the best available evidence. Because of insufficient evidence for both pnets and non-pnets, no evidence-based recommendation can be made for or against other types of targeted therapy, other ssas, chemotherapy, or combination therapy.

Randomized phase II study of modified FOLFOX-6 in combination with ramucirumab or icrucumab as second-line therapy in patients with metastatic colorectal cancer after disease progression on first-line irinotecan-based therapy.

BACKGROUND: Icrucumab and ramucirumab are recombinant human IgG1 monoclonal antibodies that bind VEGF receptors 1 and 2 (VEGFR-1 and -2), respectively. This randomized phase II study evaluated the antitumor activity and safety of icrucumab and ramucirumab each in combination with mFOLFOX-6 in patients with metastatic colorectal cancer after disease progression on first-line therapy with a fluoropyrimidine and irinotecan. PATIENTS AND METHODS: Eligible patients were randomly assigned to receive mFOLFOX-6 alone (mFOLFOX-6) or in combination with ramucirumab 8 mg/kg IV (RAM+mFOLFOX-6) or icrucumab 15 mg/kg IV (ICR+mFOLFOX-6) every 2 weeks. Randomization was stratified by prior bevacizumab therapy. The primary end point was progression-free survival (PFS). Secondary end points included overall survival (OS), tumor response, safety, and PK. RESULTS: In total, 158 patients were randomized, but only 153 received treatment (49 on mFOLFOX-6, 52 on RAM+mFOLFOX-6, and 52 on ICR+mFOLFOX-6). Median PFS was 18.4 weeks on mFOLFOX-6, 21.4 weeks on RAM+mFOLFOX-6, and 15.9 weeks on ICR+mFOLFOX-6 (RAM+mFOLFOX-6 versus mFOLFOX-6, stratified hazard ratio [HR] 1.116 [95% CI 0.713-1.745], P = 0.623; ICR+mFOLFOX-6 versus mFOLFOX-6, stratified HR 1.603 [95% CI 1.011-2.543], P = 0.044). Median survival was 53.6 weeks on mFOLFOX-6, 41.7 weeks on RAM+mFOLFOX-6, and 42.0 weeks on ICR+mFOLFOX-6. The most frequent adverse events reported on the ramucirumab arm (RAM+mFOLFOX-6) were fatigue, nausea, and peripheral sensory neuropathy; those on the icrucumab arm (ICR+mFOLFOX-6) were fatigue, diarrhea, and peripheral sensory neuropathy. Grade ≥3 serious adverse events occurred at comparable frequency across arms. CONCLUSIONS: In this study population, combining ramucirumab or icrucumab with mFOLFOX-6 did not achieve the predetermined improvement in PFS. CLINICALTRIALSGOV: NCT01111604.

Palliative chemotherapy in advanced colorectal cancer patients 80 years of age and older.

BACKGROUND: Colorectal cancer (crc) has a median diagnostic age of 68 years. Despite significant progress in chemotherapy (ctx) options, few data on outcomes or toxicity from ctx in patients 80 years of age and older are available. We investigated ctx in such patients with metastatic crc (mcrc), hypothesizing high rates of hospitalization and toxicity. METHODS: A retrospective chart review identified patients 80 years of age and older with mcrc who initiated ctx between 2005-2010 at our institution. Patient demographics and ctx data were collected. Endpoints included rates of hospitalization, ctx discontinuation because of toxicity, and overall survival. RESULTS: In 60 patients, ctx was initiated on 88 occasions. Median age in the cohort was 83 years; 52% were men; 72% lived with family; 53% had a modified Charlson comorbidity index of 2 or greater; and 31% were taking 6 or more prescription medications at baseline. At baseline, 33% of the patients were anemic (hemoglobin < 100 g/L), 36% had leukocytosis (white blood cells > 11×10(9)/L), and 48% had renal impairment (estimated glomerular filtration rate < 60 mL/min/1.73 m(2)). In 53%, ctx was given as first-line treatment. The initial ctx dose was adjusted in 67%, and capecitabine was the most common chemotherapeutic agent (45%). In 19 instances (22%), the patient was hospitalized during or within 30 days of ctx; in 26 instances (30%), the ctx was discontinued because of toxicity, and in 48 instances (55%), the patient required at least 1 dose reduction, omission, or delay. Median overall survival was 17.8 months (95% confidence interval: 14.3 to 20.8 months). CONCLUSIONS: In the population 80 years of age and older, ctx for mcrc is feasible; however, most recipients will require dose adjustments, and a significant proportion will be hospitalized or stop ctx because of toxicity. Prospective research incorporating geriatric assessment tools is required to better select these older patients for ctx.

The goal of the attendees is to improve the care of patients affected by gastrointestinal malignancies. Topics discussed during the conference included pancreatic cancer, rectal cancer, and metastatic colorectal cancer.

Eastern Canadian Gastrointestinal Cancer Consensus Conference 2016.

The annual Eastern Canadian Gastrointestinal Cancer Consensus Conference 2016 was held in Montreal, Quebec, 5-7 February. Experts in radiation oncology, medical oncology, surgical oncology, and infectious diseases involved in the management of patients with gastrointestinal malignancies participated in presentations and discussion sessions for the purpose of developing the recommendations presented here. This consensus statement addresses multiple topics: ■ Follow-up and survivorship of patients with resected colorectal cancer■ Indications for liver metastasectomy■ Treatment of oligometastases by stereotactic body radiation therapy■ Treatment of borderline resectable and unresectable pancreatic cancer■ Transarterial chemoembolization in hepatocellular carcinoma■ Infectious complications of antineoplastic agents.

Adjuvant sunitinib following chemoradiotherapy and surgery for locally advanced esophageal cancer: a phase II trial.

The prognosis for locally advanced esophageal cancer is poor despite the use of trimodality therapy. In this phase II study, we report the feasibility, tolerability and efficacy of adjuvant sunitinib. Included were patients with stage IIa, IIB or III cancer of the thoracic esophagus or gastroesophageal junction. Neoadjuvant therapy involved Irinotecan (65 mg/m2 ) + Cisplatin (30 mg/m2 ) on weeks 1 and 2, 4 and 5, 7 and 8 with concurrent radiation (50Gy/25 fractions) on weeks 4-8. Sunitinib was commenced 4-13 weeks after surgery and continued for one year. Sixty-one patients were included in the final analysis, 36 patients commenced adjuvant sunitinib. Fourteen patients discontinued sunitinib due to disease recurrence (39%) within the 12-month period, 12 (33%) discontinued due to toxicity, and 3 (8%) requested cessation of therapy. In the overall population, median survival was 26 months with a 2 and 3-year survival rate of 52% and 35%, respectively. The median survival for the 36 patients treated with sunitinib was 35 months and 2-year survival probability of 68%. In a historical control, a prior phase II study with the same trimodality therapy (n = 43), median survival was 36 months, with a 2-year survival of 67%. Initiation of adjuvant sunitinib is feasible, but poorly tolerated, with no signal of additional benefit over trimodality therapy for locally advanced esophageal cancer.

A retrospective review of cancer treatments and outcomes among Inuit referred from Nunavut, Canada.

BACKGROUND: Cancer is a health concern in Inuit populations. Unique cultural, dietary, and genetic factors and geographic isolation influence cancer epidemiology in this group. Inuit-specific data about oncology treatments and survival outcomes in Canadian Inuit referred to urban treatment centres are lacking. METHODS: A retrospective chart review of Inuit patients referred to The Ottawa Hospital Cancer Centre (tohcc) from the Baffin region of Nunavut between 2000 and 2010 was conducted. Nunavut cancer registry data were used to establish the percentage of cancer cases referred and their survival outcomes. RESULTS: Of 307 cancer patients registered among Baffin-region Inuit, 216 [70% (63 men, 153 women)] were referred to tohcc for chemotherapy (ct) and radiation therapy (rt). Mean age in the referred group was 59.3 years (range: 25-89 years), and current smokers constituted half the group (52%). The cancers most commonly leading to referral in men were lung (55%), colorectal (19%), and nasopharyngeal (11%) cancers; in women, they were lung (46%), colorectal (24%), breast (10%), nasopharyngeal (6%), and cervical (5%) cancers. Of the 216 referred patients, 82 (38%) had already undergone surgery, and 18 (8%) received chemoradiation or rt only, all given with curative intent. Among the surgical patients referred, 33 (40%) and 23 (28%) went on to receive adjuvant ct and adjuvant rt respectively. Among 116 patients referred for palliative care, 64 (55%) received ct, 76 (66%) received rt, 43 (37%) received both ct and rt, and 19 (16%) received neither treatment. Median all-stage overall survival was 10 months for patients with lung cancer [95% confidence interval: 6.1 to 13.9 months] and 37 months for patients with colorectal cancer [95% confidence interval: 14.8 to 59.2 months]. CONCLUSIONS: High uptake of palliative and adjuvant ct and rt was observed in the Inuit patients referred to tohcc. Lung cancer was the most common cancer in referred Inuit men and women. The survival rates for Inuit lung cancer patients referred to tohcc were comparable to those in the rest of Canada. Further research is required to understand reasons for non-referral of Canadian Inuit to tohcc.

Eastern Canadian Gastrointestinal Cancer Consensus Conference 2014.

The annual Eastern Canadian Colorectal Cancer Consensus Conference was held in Montreal, Quebec, 23-25 October 2014. Expert radiation, medical, and surgical oncologists and pathologists involved in the management of patients with gastrointestinal malignancies participated in presentations and discussions resulting in consensus statements on such hot topics as management of neuroendocrine tumours, advanced and metastatic pancreatic cancer, and metastatic colorectal cancer.

Review of anal cancer patients at the Ottawa hospital.

BACKGROUND: Anal cancer is uncommon. We reviewed the treatment and outcomes of anal cancer patients in a population referred to the Ottawa Hospital Cancer Centre (TOHCC) over a 12-year period. METHODS: A chart review was conducted with patient data collected from hospital records, including: demographic, treatment and outcome information. Outcomes of interest included: overall survival (OS), disease free survival (DFS), and colostomy free survival (CFS). RESULTS: 180 patients were included in the study population. 72% (n = 130) female and 28% (n = 50) male. 6.7% (n = 12 males) of patients were HIV positive - all were on anti-retroviral therapy. 60% (n = 108) of patients were ever-smokers, mean patient age was 62 [range 35-90] years. The most frequent presenting symptoms were blood per rectum and anal pain. Treatment intent was curative in 87%. Treatment included radiotherapy (94%), brachytherapy (26%), chemotherapy (73%). Among patients treated with curative-intent, 72% had a complete response, 31% had local/regional recurrence, 16% required salvage surgery and 21% had distant recurrence. The colostomy rate was 23%. 5 year overall survival (OS) was not significantly different for patients by HIV status. Survival was superior if MMC-FU was used first vs. CIS-FU; OS HR 0.47 (0.24-0.94), p < 0.033. CONCLUSIONS: The outcomes of patients in this large retrospective cohort study are similar to the outcomes of patients in highly selective clinical trials. Five year overall survival and colostomy free survival are encouraging. MMC-FU was found to be superior to CIS-FU.

Continuous versus intermittent chemotherapy strategies in metastatic colorectal cancer: a systematic review and meta-analysis.

BACKGROUND: An important goal of intermittent strategies of delivering systemic treatment as first-line treatment of metastatic colorectal cancer (mCRC) is to maintain efficacy while improving patients' quality of life (QoL). Given the varying impact on efficacy demonstrated in individual randomized, controlled trials (RCTs), a systematic review and meta-analysis of RCTs of these intermittent strategies was carried out. DESIGN: Relevant databases were systematically searched for the period 2000-2014. RCTs that compared a continuous versus intermittent strategy of delivering systemic treatment were identified by a systematic review. Overall survival (OS) hazard ratios (HRs) were extracted from the most recently reported trial results. The results of identified trials were clinically homogeneous so the data were pooled using Review Manager software (RevMan 5.1). RESULTS: Eleven RCTs were identified (n = 4 854). For the eight (n = 4508) trials with available HRs, the treatment patients received after induction was: none (five trials, n = 3036), fluoropyrimidine (one trial, n = 620), and biologic (two trials, n = 852). There were no statistically significant survival differences observed between the continuous and intermittent chemotherapy strategies. There was no statistically significant difference observed between continuous and intermittent strategies [HR = 1.03, 95% confidence interval (CI) 0.96-1.10, P = 0.38)]. Subgroup analyses demonstrated results were generally robust across induction and maintenance regimens. One subgroup analysis of the three trials (CAIRO3, OPTIMOX2, COIN, n = 2403) with combination treatment induction and no maintenance until progression revealed a statistically, but nonclinically significant benefit for continuous treatment (HR = 1.10, 95% CI 1.00-1.20, P = 0.049). QoL life was either the same in both arms in two trials (n = 912) or improved in the intermittent strategy arm in one trial (n = 1630). CONCLUSION: Intermittent strategies of delivering systemic treatment of mCRC do not result in a clinically significant reduction in OS compared with a continuous strategy of delivery, and should be part of an informed discussion of treatment options with patients with mCRC.

Strategies of sequential therapies in unresectable metastatic colorectal cancer: a meta-analysis.

BACKGROUND: Before the emergence of first-line combination chemotherapy, the standard of care for unresectable metastatic colorectal cancer (mcrc) was first-line monotherapy with modulated 5-fluorouracil. Several large phase iii randomized controlled trials, now completed, have assessed whether a planned sequential chemotherapy strategy-beginning with fluoropyrimidine monotherapy until treatment failure, followed by another regimen (either monotherapy or combination chemotherapy) until treatment failure-could result in the same survival benefit produced with an upfront combination chemotherapy strategy, but with less toxicity for patients. METHODS: The medline and embase databases, and abstracts from meetings of the American Society for Clinical Oncology and the European Society for Medical Oncology, were searched for reports comparing a sequential strategy of chemotherapy with an upfront combination chemotherapy in adult patients with mcrc. Publications that reported efficacy or toxicity data (or both) were included. RESULTS: The five eligible trials that were identified included 4532 patients. A meta-analysis of those trials demonstrates a statistically significant survival advantage for combination chemotherapy (hazard ratio: 0.92; 95% confidence interval: 0.86 to 0.99). However, the median survival advantage (3-6 weeks in most trials) is small and of questionable clinical significance. Three trials reported first-line toxicities. Upfront combination chemotherapy results in significantly more neutropenia, febrile neutropenia, thrombocytopenia, diarrhea, nausea, vomiting, and sensory neuropathy. Sequential chemotherapy results in significantly more hand-foot syndrome. CONCLUSIONS: Given the small survival advantage associated with upfront combination chemotherapy, planned sequential chemotherapy and upfront combination chemotherapy can both be considered treatment strategies. Treatment should be chosen on an individual basis considering patient and tumour characteristics, toxicity of each strategy, and patient preference.

Use of chemotherapy and radiofrequency ablation to treat colorectal cancer metastases: a retrospective review of The Ottawa Hospital Cancer Centre over 7 years.

BACKGROUND: Almost 40% of people diagnosed with colorectal cancer will die from their disease, most with metastatic spread. When feasible, hepatic resection offers the greatest probability of cure for isolated liver metastases, but there are barriers to curative resection. Those barriers include the extent and distribution of lesions within the liver, extrahepatic disease, comorbidities, and age. Chemotherapy is often administered before or after resection with the intention of improving disease-free and overall survival. The timing of chemotherapy (adjuvant vs. neoadjuvant vs. perioperative) for patients undergoing potentially curative hepatic resection of metastasis of colorectal cancer origin is controversial. METHODS: Colorectal cancer patients with liver metastases resected at The Ottawa Hospital between January 1, 2003, and December 31, 2009, were identified, and their clinical records were retrospectively reviewed. Patients receiving intraoperative radiofrequency ablation (rfa) as part of their management were included. Factors associated with overall and disease-free survival were evaluated. RESULTS: The 168 identified patients (57% men, 43% women) had a median age of 63 years (range: 31-84 years). After hepatectomy, 10% had positive resection margins. Intraoperative rfa was used in 25 patients (15%). Chemotherapy was administered in the neoadjuvant (19%), adjuvant (31%), or "perioperative" (both neoadjuvant and adjuvant, 50%) setting. Use or omission of intraoperative rfa was not associated with a difference in overall survival (hazard ratio: 0.99; 95% confidence interval: 0.53 to 1.84; p = 0.97). CONCLUSIONS: Compared with patients who did not receive chemotherapy, those who received chemotherapy, regardless of timing, experienced improved overall survival and disease-free survival. Use of rfa where required as an adjunct to hepatic resection appears to be effective and is not associated with worse overall survival.

Role of neoadjuvant therapy in the management of pancreatic cancer: is the era of biomarker-directed therapy here?

Pancreatic cancer is the 4th leading cause of cancer-related death. Complete surgical resection (CR0) is considered the only curative treatment. Most patients present with unresectable or borderline resectable disease. Many small phase i/ii trials have tried to address the role of neoadjuvant treatment using chemotherapy with or without chemoradiation in the management of locally advanced disease. However, many of them looked at the rate of CR0 resection and the feasibility of such treatment. A trend for improved overall survival has been observed in the group of patients with borderline resectable disease who completed neoadjuvant treatment. A large proportion of patients progress while on treatment, sparing them from unnecessary surgery. We searched the PubMed database (using the key words "pancreatic cancer," or "pancreatic neoplasm," or "pancreatic adenocarcinoma," and "neoadjuvant treatment," or "neoadjuvant chemotherapy," or "neoadjuvant radiation therapy," or "neoadjuvant chemo-radiation," or "adjuvant therapy" [all fields] and "clinical trial" or "study") and abstracts presented at the American Society of Clinical Oncology meetings on gastrointestinal cancers. Here, we review the most recent papers that present results on neoadjuvant therapy in pancreatic cancer. All but one report used overall survival as an endpoint. Unfortunately, there are no valid biomarkers predicting tumour progression or recurrence, and response to treatment than can help to guide therapeutic choices. Our recommendation is to consider neoadjuvant treatment in cases of borderline resectable disease. In patients with primary resectable tumours, surgery followed by adjuvant treatment and enrollment on adjuvant treatment studies would be appropriate.

Hepatic arterial infusion pump chemotherapy in the management of colorectal liver metastases: expert consensus statement.

Despite significant improvements in systemic therapy for patients with colorectal liver metastases (crlms), response rates in the first-line setting are not optimal, and response rates in the second-line setting remain disappointing. Hepatic arterial infusion pump (haip) chemotherapy has been extensively studied in patients with crlms, but it remains infrequently used. We convened an expert panel to discuss the role of haip in the contemporary management of patients with crlm. Using a consensus process, we developed these statements: haip chemotherapy should be given in combination with systemic chemotherapy.haip chemotherapy should be offered in the context of a multidisciplinary program that includes expertise in hepatobiliary surgery, medical oncology, interventional radiology, nursing, and nuclear medicine.haip chemotherapy in combination with systemic therapy should be considered in patients with unresectable crlms who have progressed on first-line systemic treatment. In addition, haip chemotherapy is acceptable as first-line treatment in patients with unresectable colorectal liver metastases.haip chemotherapy is not recommended in the setting of extrahepatic disease outside the context of a clinical trial.haip chemotherapy in combination with systemic therapy is an option for select patients with resected colorectal liver metastases. These consensus statements provide a framework that clinicians who treat patients with crlm can use when considering treatment with haip.
