Evaluation of Culture Conducive to Academic Success by Gender at a Comprehensive Cancer Center.

INTRODUCTION: The primary objective of this study was to determine whether workplace culture in academic oncology differed by gender, during the COVID-19 pandemic. MATERIALS AND METHODS: We used the Culture Conducive to Women's Academic Success (CCWAS), a validated survey tool, to investigate the academic climate at an NCI-designated Cancer Center. We adapted the CCWAS to be applicable to people of all genders. The full membership of the Cancer Center was surveyed (total faculty = 429). The questions in each of 4 CCWAS domains (equal access to opportunities, work-life balance, freedom from gender bias, and leadership support) were scored using a 5-point Likert scale. Median score and interquartile ranges for each domain were calculated. RESULTS: A total of 168 respondents (men = 58, women = 106, n = 4 not disclosed) submitted survey responses. The response rate was 39% overall and 70% among women faculty. We found significant differences in perceptions of workplace culture by gender, both in responses to individual questions and in the overall score in the following domains: equal access to opportunities, work-life balance, and leader support, and in the total score for the CCWAS. CONCLUSIONS: Our survey is the first of its kind completed during the COVID-19 pandemic at an NCI-designated Cancer Center, in which myriad factors contributed to burnout and workplace challenges. These results point to specific issues that detract from the success of women pursuing careers in academic oncology. Identifying these issues can be used to design and implement solutions to improve workforce culture, mitigate gender bias, and retain faculty.

NCCN Guidelines® Insights: Biliary Tract Cancers, Version 2.2023.

In 2023, the NCCN Guidelines for Hepatobiliary Cancers were divided into 2 separate guidelines: Hepatocellular Carcinoma and Biliary Tract Cancers. The NCCN Guidelines for Biliary Tract Cancers provide recommendations for the evaluation and comprehensive care of patients with gallbladder cancer, intrahepatic cholangiocarcinoma, and extrahepatic cholangiocarcinoma. The multidisciplinary panel of experts meets at least on an annual basis to review requests from internal and external entities as well as to evaluate new data on current and emerging therapies. These Guidelines Insights focus on some of the recent updates to the NCCN Guidelines for Biliary Tract Cancers as well as the newly published section on principles of molecular testing.

Preoperative Treatment of Locally Advanced Rectal Cancer.

BACKGROUND: Pelvic radiation plus sensitizing chemotherapy with a fluoropyrimidine (chemoradiotherapy) before surgery is standard care for locally advanced rectal cancer in North America. Whether neoadjuvant chemotherapy with fluorouracil, leucovorin, and oxaliplatin (FOLFOX) can be used in lieu of chemoradiotherapy is uncertain. METHODS: We conducted a multicenter, unblinded, noninferiority, randomized trial of neoadjuvant FOLFOX (with chemoradiotherapy given only if the primary tumor decreased in size by <20% or if FOLFOX was discontinued because of side effects) as compared with chemoradiotherapy. Adults with rectal cancer that had been clinically staged as T2 node-positive, T3 node-negative, or T3 node-positive who were candidates for sphincter-sparing surgery were eligible to participate. The primary end point was disease-free survival. Noninferiority would be claimed if the upper limit of the two-sided 90.2% confidence interval of the hazard ratio for disease recurrence or death did not exceed 1.29. Secondary end points included overall survival, local recurrence (in a time-to-event analysis), complete pathological resection, complete response, and toxic effects. RESULTS: From June 2012 through December 2018, a total of 1194 patients underwent randomization and 1128 started treatment; among those who started treatment, 585 were in the FOLFOX group and 543 in the chemoradiotherapy group. At a median follow-up of 58 months, FOLFOX was noninferior to chemoradiotherapy for disease-free survival (hazard ratio for disease recurrence or death, 0.92; 90.2% confidence interval [CI], 0.74 to 1.14; P = 0.005 for noninferiority). Five-year disease-free survival was 80.8% (95% CI, 77.9 to 83.7) in the FOLFOX group and 78.6% (95% CI, 75.4 to 81.8) in the chemoradiotherapy group. The groups were similar with respect to overall survival (hazard ratio for death, 1.04; 95% CI, 0.74 to 1.44) and local recurrence (hazard ratio, 1.18; 95% CI, 0.44 to 3.16). In the FOLFOX group, 53 patients (9.1%) received preoperative chemoradiotherapy and 8 (1.4%) received postoperative chemoradiotherapy. CONCLUSIONS: In patients with locally advanced rectal cancer who were eligible for sphincter-sparing surgery, preoperative FOLFOX was noninferior to preoperative chemoradiotherapy with respect to disease-free survival.

Phase III Prospectively Randomized Trial of Perioperative 5-FU After Curative Resection for Colon Cancer: An Intergroup Trial of the ECOG-ACRIN Cancer Research Group (E1292).

BACKGROUND: Studies suggest that adjuvant chemotherapy should be initiated at the earliest possible time. The Eastern Cooperative Oncology Group (ECOG) and Intergroup evaluated the effect of perioperative fluorouracil (5-FU) on overall survival (OS) for colon cancer. PATIENTS AND METHODS: This phase III trial randomized patients to receive continuous infusional 5-FU for 7 days starting within 24 h after curative resection (arm A) or no perioperative 5-FU (arm B). Patients with Dukes' B3 and C disease received adjuvant chemotherapy per standard of care. The primary endpoint of the trial was overall survival in patients with Dukes' B3 and C disease. The secondary objective was to determine whether a week of perioperative infusion would affect survival in patients with Dukes' B2 colon cancer with no additional chemotherapy. RESULTS: From August 1993 to May 2000, 859 patients were enrolled and 855 randomized (arm A: 427; arm B: 428). The trial was terminated early due to slow accrual. The median follow-up is 15.4 years (0.03-20.3 years). Among patients with Dukes' B3 and C disease, there was no statistically significant difference in OS [median 10.3 years (95% CI 8.4, 13.2) for perioperative chemotherapy and 9.3 years (95% CI 5.7, 12.3) for no perioperative therapy, one-sided log-rank p = 0.178, HR = 0.88 (95% CI 0.66, 1.16)] or disease-free survival (DFS). For patients with Dukes' B2 disease, there was also no significant difference in OS (median 16.1 versus 12.9 years) or DFS. There was no difference between treatment arms in operative complications. One week of continuous infusion of 5-FU was tolerable; 18% of arm A patients experienced grade 3 or greater toxicity.

Being Present 2.0: Online Mindfulness-Based Program for Metastatic Gastrointestinal Cancer Patients and Caregivers.

PURPOSE: A metastatic cancer diagnosis is associated with high levels of distress in patients and caregivers, which may be alleviated by mindfulness interventions. Research on scalable, tailored, online mindfulness training programs is needed. We sought to test the feasibility and acceptability of a remotely delivered 8-week mindfulness-based intervention, Being Present 2.0 (BP2.0). METHODS: We performed a single-arm feasibility study of BP2.0 among patients with any metastatic gastrointestinal cancer receiving chemotherapy, with or without an informal caregiver. Participants were instructed to practice mindfulness using pre-recorded guided meditations 5 times per week using a study-specific website and to attend a weekly live, interactive virtual meeting facilitated by a trained instructor. The web-based platform enabled direct measurement of adherence. RESULTS: The study enrolled 46 of 74 (62%) patients contacted, together with 23 caregivers (69 participants total), from May to October 2018. Median patient age was 52 (range 20-70 years), 39% were male, 67% non-Hispanic white, 65% had colorectal cancer, and 78% lived outside of San Francisco. The top reasons cited for participation were to reduce stress/anxiety and learn how to meditate. Mean baseline National Comprehensive Cancer Network Distress Thermometer (NCCN DT) scores were 4.7 (patients) and 5.8 (caregivers). The study discontinuation rate was 20% (eight patients and six caregivers). Among the remaining 55 participants, 43 (78%) listened to at least one audio recording and/or attended at least one virtual meeting, although adherence data was incomplete. The retention rate was 71%, with 39 participants completing at least one follow-up assessment. In post-intervention qualitative interviews, 88% of respondents reported a positive experience. Compared to baseline, participants reported significantly reduced post-intervention NCCN DT scores (mean 3.1; P = .012). CONCLUSION: The BP2.0 online mindfulness-based program is feasible and acceptable for patients with metastatic gastrointestinal cancer and caregivers. These results will guide plans for a follow-up efficacy study. ClinicalTrials.gov Identifier: NCT03528863.

Association of Coffee Intake With Survival in Patients With Advanced or Metastatic Colorectal Cancer.

IMPORTANCE: Several compounds found in coffee possess antioxidant, anti-inflammatory, and insulin-sensitizing effects, which may contribute to anticancer activity. Epidemiological studies have identified associations between increased coffee consumption and decreased recurrence and mortality of colorectal cancer. The association between coffee consumption and survival in patients with advanced or metastatic colorectal cancer is unknown. OBJECTIVE: To evaluate the association of coffee consumption with disease progression and death in patients with advanced or metastatic colorectal cancer. DESIGN, SETTING, AND PARTICIPANTS: This prospective observational cohort study included 1171 patients with previously untreated locally advanced or metastatic colorectal cancer who were enrolled in Cancer and Leukemia Group B (Alliance)/SWOG 80405, a completed phase 3 clinical trial comparing the addition of cetuximab and/or bevacizumab to standard chemotherapy. Patients reported dietary intake using a semiquantitative food frequency questionnaire at the time of enrollment. Data were collected from October 27, 2005, to January 18, 2018, and analyzed from May 1 to August 31, 2018. EXPOSURES: Consumption of total, decaffeinated, and caffeinated coffee measured in cups per day. MAIN OUTCOMES AND MEASURES: Overall survival (OS) and progression-free survival (PFS). RESULTS: Among the 1171 patients included in the analysis (694 men [59%]; median age, 59 [interquartile range, 51-67] years). The median follow-up time among living patients was 5.4 years (10th percentile, 1.3 years; IQR, 3.2-6.3 years). A total of 1092 patients (93%) had died or had disease progression. Increased consumption of coffee was associated with decreased risk of cancer progression (hazard ratio [HR] for 1-cup/d increment, 0.95; 95% CI, 0.91-1.00; P = .04 for trend) and death (HR for 1-cup/d increment, 0.93; 95% CI, 0.89-0.98; P = .004 for trend). Participants who consumed 2 to 3 cups of coffee per day had a multivariable HR for OS of 0.82 (95% CI, 0.67-1.00) and for PFS of 0.82 (95% CI, 0.68-0.99), compared with those who did not drink coffee. Participants who consumed at least 4 cups of coffee per day had a multivariable HR for OS of 0.64 (95% CI, 0.46-0.87) and for PFS of 0.78 (95% CI, 0.59-1.05). Significant associations were noted for both caffeinated and decaffeinated coffee. CONCLUSIONS AND RELEVANCE: Coffee consumption may be associated with reduced risk of disease progression and death in patients with advanced or metastatic colorectal cancer. Further research is warranted to elucidate underlying biological mechanisms.

Plasma 25-Hydroxyvitamin D Levels and Survival in Patients with Advanced or Metastatic Colorectal Cancer: Findings from CALGB/SWOG 80405 (Alliance).

PURPOSE: Previous studies have suggested that higher circulating 25-hydroxyvitamin D [25(OH)D] levels are associated with decreased colorectal cancer risk and improved survival. However, the influence of vitamin D status on disease progression and patient survival remains largely unknown for patients with advanced or metastatic colorectal cancer. EXPERIMENTAL DESIGN: We prospectively collected blood samples in 1,041 patients with previously untreated advanced or metastatic colorectal cancer participating in a randomized phase III clinical trial of first-line chemotherapy plus biologic therapy. We examined the association of baseline plasma 25(OH)D levels with overall survival (OS) and progression-free survival (PFS). Cox proportional hazards models were used to calculate hazard ratios (HRs) and confidence intervals (CIs), adjusted for prognostic factors and confounders. RESULTS: At study entry, 63% of patients were vitamin D deficient (<20 ng/mL) and 31% were vitamin D insufficient (20-<30 ng/mL). Higher 25(OH)D levels were associated with an improvement in OS and PFS (P trend = 0.0009 and 0.03, respectively). Compared with patients in the bottom quintile of 25(OH)D (≤10.8 ng/mL), those in the top quintile (≥24.1 ng/mL) had a multivariable-adjusted HR of 0.66 (95% CI, 0.53-0.83) for OS and 0.81 (95% CI, 0.66-1.00) for PFS. The improved survival associated with higher 25(OH)D levels was consistent across patient subgroups of prognostic patient and tumor characteristics. CONCLUSIONS: In this large cohort of patients with advanced or metastatic colorectal cancer, higher plasma 25(OH)D levels were associated with improved OS and PFS. Clinical trials assessing the benefit of vitamin D supplementation in patients with colorectal cancer are warranted.

Vitamin D Levels in Patients with Colorectal Cancer and Matched Household Members.

BACKGROUND: Vitamin D levels, as measured by 25-hydroxyvitamin-D [25(OH) D], are inversely related to the risk of developing colorectal cancer (CRC). Given shared demographic and lifestyle factors among members of the same household, we sought to examine vitamin D levels and associated lifestyle factors in household members of CRC patients. METHODS: Thirty patients with pathologically confirmed CRC were enrolled prior to oncologic therapy along with unrelated household members who were matched for age (+/- 5 years) and race. In addition to serum blood draws for 25(OH)D levels at baseline and six-month follow-up, questionnaires collected gender, vitamin use, body mass index, family history of CRC, race, dietary vitamin D, UV exposure, and exercise. RESULTS: Median serum 25(OH) D levels were 26.8 ng/mL for CRC patients versus 27.3 for household members (P=0.89). Vitamin-D associated factors such as dietary vitamin D intake, UV exposure, gender, multivitamin use, vitamin D supplement use, and family history of CRC were not significantly different between CRC patients and paired household members (P>0.05). Household members were more likely than CRC patients to be overweight and to exercise more. CONCLUSIONS: Vitamin D levels and many associated lifestyle factors were not significantly different between CRC patients and unrelated paired household members. Given comparable vitamin D levels, further investigation into whether age-matched household members of CRC patients may be at increased risk for CRC is warranted.

Vitamin D Levels in Patients with Colorectal Cancer Before and After Treatment Initiation.

PURPOSE: We aimed to described 25-hydroxyvitamin D [25(OH)D] levels in newly diagnosed colorectal cancer (CRC) patients and to re-evaluate levels after chemotherapy. METHODS: Permanent residents of the San Francisco Bay Area with a new CRC diagnosis of any stage were recruited prior to any non-surgical therapy. Serum 25(OH)D levels were measured at time of diagnosis and 6-month follow-up. Supplement use was not restricted. The primary endpoint was the frequency of vitamin D deficiency in patients with newly diagnosed CRC of all stages. The Kruskal-Wallis and Spearman correlation tests were used to evaluate associations of patient characteristics with 25(OH)D levels. RESULTS: Median 25(OH)D level at baseline was 27.0 ng/mL (range 7.2, 59.0); 65% of patients had insufficient levels (25(OH)D < 30 ng/mL) (n = 94). Race, disease stage, multivitamin use, vitamin D supplementation, and county of residence were associated with baseline 25(OH)D levels (P < 0.05). The median change in 25(OH)D from baseline to 6 months was - 0.7 ng/mL [- 19.4, 51.7] for patients treated with chemotherapy (n = 58) and 1.6 ng/mL [- 6.4, 33.2] for patients who did not receive chemotherapy (n = 19) (P = 0.26). For patients who received vitamin D supplementation during chemotherapy, the median 25(OH)D change was 8.3 ng/mL [- 7.6, 51.7] versus - 1.6 [- 19.4, 24.3] for chemotherapy patients who did not take vitamin D supplements (P = 0.02). CONCLUSION: Among patients with a new diagnosis of CRC, most patients were found to have 25(OH)D levels consistent with either deficiency or insufficiency. In the subset of patients who received chemotherapy and took a vitamin D supplement, serum 25(OH)D levels increased, suggesting that vitamin D repletion is a feasible intervention during chemotherapy.

Being Present: A single-arm feasibility study of audio-based mindfulness meditation for colorectal cancer patients and caregivers.

A metastatic cancer diagnosis is associated with high levels of distress in patients and caregivers. Mindfulness interventions can reduce distress and improve quality of life in cancer patients. However, standard mindfulness training relies on in-person instruction, which is often not practical for either patients receiving chemotherapy or their caregivers. In the Being Present single arm pilot study, we designed and tested an 8-week audio-based mindfulness meditation program for patients with metastatic colorectal cancer receiving chemotherapy with or without a participating caregiver. The study accrued 33 of 74 (45%) eligible patients consenting together with 20 family caregivers (53 participants total) within nine months. Forty-one participants were evaluable (77%); 10 of 12 cases of attrition were attributable to hospitalization or death. Median participant age was 51 (range 21-78 years); 38% were men. Baseline levels of distress were similar in patients and caregivers. The top reasons for participation cited in pre-intervention interviews were to increase relaxation/calm, improve mood/emotions, and reduce stress/anxiety. In measures of adherence, 59% of responses to weekly texts asking: "Have you practiced today?" were "Yes" and 59% of interviewees reported practicing >50% of the time. Compared to baseline, post-intervention surveys demonstrated significantly reduced distress (p = 0.01) and anxiety (p = 0.03); as well as increased non-reactivity (p<0.01), and feeling at peace (p<0.01). Post-intervention qualitative interviews, where 71% of participants reported benefit, were consistent with quantitative findings. In the interviews, participants spontaneously described reduced stress/anxiety and increased relaxation/calm. Benefits appeared to be accentuated in patient-caregiver pairs as compared to unpaired patients. Seventy-nine percent of participants reported plans for continued practice after study completion. We conclude that the Being Present audio-based mindfulness meditation program is of interest to, feasible, and acceptable for patients with metastatic colorectal cancer and caregivers, with initial evidence of efficacy. These results will guide plans for a follow-up study. TRIAL REGISTRATION: ClinicalTrials.gov NCT02423720.

Optimizing Adjuvant Therapy for Localized Colon Cancer and Treatment Selection in Advanced Colorectal Cancer.

Results from the pivotal IDEA trial, which evaluated 3 versus 6 months of adjuvant oxaliplatin-based chemotherapy, are incorporated into the NCCN Guidelines for Colon Cancer. The guidelines recommend that for patients with low-risk stage III disease, the preferred regimen is CAPEOX for 3 months or FOLFOX for 3 to 6 months. For patients with high-risk stage III disease, the preferred regimen is CAPEOX for 3 to 6 months or FOLFOX for 6 months. In metastatic disease, tumor sidedness should be a consideration when choosing a biologic. For BRAF-mutated disease, several triplets are now recommended options. Importantly, for a subset of patients with metastatic disease, new to the NCCN Guidelines is the incorporation of nivolumab and pembrolizumab as subsequent therapy for those with microsatellite instability-high or mismatch repair-deficient tumors.

Adjuvant Chemoradiotherapy With Epirubicin, Cisplatin, and Fluorouracil Compared With Adjuvant Chemoradiotherapy With Fluorouracil and Leucovorin After Curative Resection of Gastric Cancer: Results From CALGB 80101 (Alliance).

Purpose After curative resection of gastric or gastroesophageal junction adenocarcinoma, Intergroup Trial 0116 (Phase III trial of postoperative adjuvant radiochemotherapy for high risk gastric and gastroesophageal junction adenocarcinoma: Demonstrated superior survival for patients who received postoperative chemoradiotherapy with bolus fluorouracil (FU) and leucovorin (LV) compared with surgery alone. CALGB 80101 (Alliance; Phase III Intergroup Trial of Adjuvant Chemoradiation After Resection of Gastric or Gastroesophageal Adenocarcinoma) assessed whether a postoperative chemoradiotherapy regimen that replaced FU plus LV with a potentially more active systemic therapy could further improve overall survival. Patients and Methods Between April 2002 and May 2009, 546 patients who had undergone a curative resection of stage IB through IV (M0) gastric or gastroesophageal junction adenocarcinoma were randomly assigned to receive either postoperative FU plus LV before and after combined FU and radiotherapy (FU plus LV arm) or postoperative epirubicin, cisplatin, and infusional FU (ECF) before and after combined FU and radiotherapy (ECF arm). Results With a median follow-up duration of 6.5 years, 5-year overall survival rates were 44% in the FU plus LV arm and 44% in the ECF arm ( Plogrank = .69; multivariable hazard ratio, 0.98; 95% CI, 0.78 to 1.24 comparing ECF with FU plus LV). Five-year disease-free survival rates were 39% in the FU plus LV arm and 37% in the ECF arm ( Plogrank = .94; multivariable hazard ratio, 0.96; 95% CI, 0.77 to 1.20). In post hoc analyses, the effect of treatment seemed to be similar across all examined patient subgroups. Conclusion After a curative resection of gastric or gastroesophageal junction adenocarcinoma, postoperative chemoradiotherapy using a multiagent regimen of ECF before and after radiotherapy does not improve survival compared with standard FU and LV before and after radiotherapy.

Prolonged Response to HER2-Directed Therapy in a Patient With HER2-Amplified, Rapidly Progressive Metastatic Colorectal Cancer.

HER2 gene amplifications and activating mutations in the HER2 receptor tyrosine kinase are present in 4% of metastatic colorectal cancers (mCRCs). HER2-targeted therapy is not standard of care, although preclinical and clinical data suggest that patients with HER2 amplifications and/or HER2-activating mutations may benefit from HER2-directed therapy. HER2 amplifications and activating mutations have also been implicated in resistance to anti-epidermal growth factor receptor-based therapy. This report describes a patient with KRAS, NRAS, and BRAF wild-type mCRC who experienced disease progression on first-line treatment with FOLFIRI and cetuximab after only 5 months, and subsequently experienced progression on second-line treatment with capecitabine and oxaliplatin plus bevacizumab after 2 months with significant functional decline. Next-generation sequencing of the primary tumor identified HER2 amplification, and we were able to obtain trastuzumab-DM1 for off-label use. The patient had symptomatic clinical benefit from trastuzumab-DM1 and had radiographic disease control for 7 months. On progression, therapy was changed to trastuzumab and pertuzumab, but the patient's disease progressed 3 months later. Treatment with the trastuzumab-DM1 resulted in a sustained response that was longer than his prior responses in the first and second lines of treatment, with a dramatic improvement in the patient's functional status. This case represents the first report, to our knowledge, of successful single-agent treatment of HER2-amplifed CRC with trastuzumab-DM1. Clinical trials targeting patients with HER2-mutated and -amplified metastatic colon cancer are currently underway. Molecular insights from investigating HER2 activation and the impact of HER2-directed therapies in a wide variety of solid tumors will create the needed evidence base to more broadly inform patient care.

Observational registry of sorafenib use in clinical practice across Child-Pugh subgroups: The GIDEON study.

BACKGROUND & AIMS: GIDEON (Global Investigation of therapeutic DEcisions in hepatocellular carcinoma and Of its treatment with sorafeNib) is a prospective, observational registry study evaluating the safety of sorafenib and treatment practices in hepatocellular carcinoma patients. This large global database allowed for assessment of the use and tolerability of sorafenib in patients with liver dysfunction. METHODS: Baseline characteristics and medical/treatment history were collected in patients for whom a decision to treat with sorafenib had been made. Adverse event, dosing, and outcomes data were collected during follow-up. RESULTS: In the overall safety population (n=3202), 1968 patients (61%) had Child-Pugh A status and 666 (21%) had Child-Pugh B. The majority of Child-Pugh A (72%) and Child-Pugh B (70%) patients received an initial sorafenib dose of 800mg, consistent with the label, and dose reduction rates were 40% and 29%, respectively. The type and incidence of adverse events were generally consistent across Child-Pugh subgroups. The incidence of drug-related adverse events leading to discontinuation was similar between Child-Pugh A and Child-Pugh B patients (17% and 21%). In the intent-to-treat population (n=3213), median overall survival (months [95% confidence interval]) was longer in Child-Pugh A patients (13.6 [12.8-14.7]) compared with Child-Pugh B patients (5.2 [4.6-6.3]). CONCLUSIONS: In clinical practice, the safety profile of sorafenib appeared to be consistent across Child-Pugh A and Child-Pugh B patients. Findings suggest sorafenib may be safely used in some Child-Pugh B patients and indicate the importance of careful patient evaluation when making treatment decisions. LAY SUMMARY: The GIDEON (Global Investigation of therapeutic DEcisions in hepatocellular carcinoma and Of its treatment with sorafeNib) study is a large prospective registry of patients with liver cancer who were treated with sorafenib. The aims were to evaluate the safety and tolerability of sorafenib among those in which the liver was not functioning properly. The study showed that the safety profile of sorafenib was consistent across patients with preserved liver function and those in which the liver was not functioning properly, and therefore, suggesting that sorafenib may be a valid treatment for some patients with liver impairment.

Regional differences in sorafenib-treated patients with hepatocellular carcinoma: GIDEON observational study.

BACKGROUND & AIMS: Treatment approaches for hepatocellular carcinoma (HCC) vary across countries, but these differences and their potential impact on outcomes have not been comprehensively assessed. Data from the multinational GIDEON (Global Investigation of therapeutic DEcisions in HCC and Of its treatment with sorafeNib) registry evaluated differences in patient characteristics, practice patterns and outcomes in HCC across geographical regions in patients who received sorafenib. METHODS: GIDEON is a non-randomised, observational registry study conducted in 39 countries across five global regions. HCC patients in whom a decision to treat with sorafenib was made in clinical practice and according to local practices were included. RESULTS: 3202 patients were evaluable for safety analysis: Asia-Pacific (n = 928), Japan (n = 508), Europe (n = 1113), USA (n = 563) and Latin America (n = 90). Patients in Japan had earlier-stage disease at initial diagnosis compared with patients in other regions (Barcelona Clinic Liver Cancer stage A; 43.7% vs 9.1-24.3%). Use of locoregional therapies before sorafenib, including transarterial chemoembolisation, was more common in Japan (84.4%) and Asia-Pacific (67.2%) compared with the USA (49.4%) and Europe (43.5%). Treatment patterns with respect to sorafenib also differed, with a shorter duration of treatment reported in the USA and Asia-Pacific. Time from initial diagnosis to death was longer in Japan compared with other regions (median, 79.6 months vs 14.8-25.0 months). CONCLUSIONS: Data from GIDEON highlight regional variations in the management of HCC and patient outcomes. Greater standardisation of management may help optimise outcomes for HCC patients.

TACE Treatment in Patients with Sorafenib-treated Unresectable Hepatocellular Carcinoma in Clinical Practice: Final Analysis of GIDEON.

PURPOSE: To evaluate transarterial chemoembolization (TACE) use prior to and concomitantly with sorafenib in patients with unresectable hepatocellular carcinoma (HCC) across different global regions. MATERIALS AND METHODS: GIDEON is an observational registry study of more than 3000 HCC patients. Patients with histologically, cytologically, or radiographically diagnosed HCC, and for whom a decision had been made to treat with sorafenib, were eligible. Patients were enrolled into the registry from 39 countries beginning in January 2009, with the last patient follow-up in April 2012. Detailed data on treatment history, treatment patterns, adverse events, and outcomes were collected. All treatment decisions were at the discretion of the treating physicians. Documented approval from local ethics committees was obtained, and all patients provided signed informed consent. Descriptive statistics, including minimum, median, and maximum, were calculated for metric data, and frequency tables for categorical data. Kaplan-Meier estimates with 95% confidence intervals were calculated for survival end points. RESULTS: A total of 3202 patients were eligible for safety analysis, of whom 2631 (82.2%) were male. Median age was 62 years (range, 15-98 years). A total of 1511 (47.2%) patients underwent TACE prior to sorafenib; 325 (10.1%) underwent TACE concomitantly. TACE prior to sorafenib was more common in Japan and Asia-Pacific compared with all other regions (362 [71.3%] and 560 [60.3%] vs 12-209 [13.3%-37.1%]). Adverse events were reported in 2732 (85.3%) patients overall, with no notable differences in the incidence of adverse events, regardless of TACE treatment history. Overall survival was 12.7 months in prior-TACE patients, 9.2 months in non-prior-TACE patients, 21.6 months in concomitant-TACE patients, and 9.7 months in non-concomitant-TACE patients. CONCLUSION: Global variation exists in TACE use in sorafenib-treated HCC patients. The combination of TACE with sorafenib appears to be a well-tolerated and viable therapeutic approach.

Aspirin and COX-2 inhibitor use in patients with stage III colon cancer.

We conducted a prospective, observational study of aspirin and COX-2 inhibitor use and survival in stage III colon cancer patients enrolled in an adjuvant chemotherapy trial. Among 799 eligible patients, aspirin use was associated with improved recurrence-free survival (RFS) (multivariable hazard ratio [HR] = 0.51, 95% confidence interval [CI] = 0.28 to 0.95), disease-free survival (DFS) (HR = 0.68, 95% CI = 0.42 to 1.11), and overall survival (OS) (HR = 0.63, 95% CI = 0.35 to 1.12). Adjusted HRs for DFS and OS censored at five years (in an attempt to minimize misclassification from noncancer death) were 0.61 (95% CI = 0.36 to 1.04) and 0.48 (95% CI = 0.23 to 0.99). Among 843 eligible patients, those who used COX-2 inhibitors had multivariable HRs for RFS, DFS, and OS of 0.53 (95% CI = 0.27 to 1.04), 0.60 (95% CI = 0.33 to 1.08), and 0.50 (95% CI = 0.23 to 1.07), and HRs of 0.47 (95% CI = 0.24 to 0.91) and 0.26 (95% CI = 0.08 to 0.81) for DFS and OS censored at five years. Aspirin and COX-2 inhibitor use may be associated with improved outcomes in stage III colon cancer patients.

Comparison of dietary and lifestyle habits among stage III and metastatic colorectal cancer patients: findings from CALGB 89803 and CALGB 80405.

UNLABELLED: Self-administered questionnaires were completed by patients undergoing chemotherapy for stage III colon cancer (n=1095) and metastatic colorectal cancer (n=875). We describe the prevalence of a wide-range of health-related dietary patterns and lifestyle behaviors among colorectal cancer patients with stage III and metastatic disease and report notable similarities in these 2 cohorts. BACKGROUND: Cancer patients often pursue lifestyle and dietary changes with the aim to improve outcomes. Using data from 2 large National Cancer Institute-sponsored clinical trials, we report on the dietary and lifestyle practices of patients receiving therapy for stage III colon or metastatic colorectal cancer. PATIENTS AND METHODS: Self-administered questionnaires were completed by patients undergoing chemotherapy for stage III colon cancer (n=1095) and metastatic colorectal cancer (n=875). Descriptive statistical analyses were performed to evaluate anthropometrics, diet, and lifestyle in each cohort. RESULTS: Median body mass index was comparable for stage III and metastatic patients (27.3 vs. 26.5 kg/m2). Stage III patients reported a modestly higher median level of physical activity than metastatic patients (4.6 vs. 3.4 metabolic equivalent task-hours per week). Ten percent of stage III and 9% of metastatic patients reported ongoing cigarette use. Avoidance of alcohol was reported by 47% of stage III and 43% of metastatic patients. Dietary patterns for both groups were comparable with more than 80% of stage III and metastatic patients failing to meet the recommended daily intake of vegetables, fruits, and milk products. Usage of at least 2 multivitamins per week was reported by 49% of stage III and 40% of metastatic patients. Two percent of stage III and 5% of metastatic patients reported vitamin D supplement use. CONCLUSIONS: We observed notable similarities in dietary and lifestyle behaviors between stage III colon and metastatic colorectal cancer patients actively receiving chemotherapy. Future research should aim to elucidate the effect of these behaviors on patient outcomes.

Rectal cancer.

These NCCN Clinical Practice Guidelines in Oncology provide recommendations for the management of rectal cancer, beginning with the clinical presentation of the patient to the primary care physician or gastroenterologist through diagnosis, pathologic staging, neoadjuvant treatment, surgical management, adjuvant treatment, surveillance, management of recurrent and metastatic disease, and survivorship. This discussion focuses on localized disease. The NCCN Rectal Cancer Panel believes that a multidisciplinary approach, including representation from gastroenterology, medical oncology, surgical oncology, radiation oncology, and radiology, is necessary for treating patients with rectal cancer.
