Item Age and comorbidity association with survival outcomes in metastatic colorectal cancer: CALGB 80405 analysis(Elsevier, 2022) McCleary, Nadine J.; Zhang, Sui; Ma, Chao; Ou, Fang-Shu; Bainter, Tiffany M.; Venook, Alan P.; Niedzwiecki, Donna; Lenz, Heinz-Josef; Innocenti, Federico; O'Neil, Bert H.; Polite, Blase N.; Hochster, Howard S.; Atkins, James N.; Goldberg, Richard M.; Ng, Kimmie; Mayer, Robert J.; Blanke, Charles D.; O'Reilly, Eileen M.; Fuchs, Charles S.; Meyerhardt, Jeffrey A.; Medicine, School of MedicineBackground: Little is known about the interaction of comorbidities and age on survival outcomes in colorectal cancer (mCRC), nor how comorbidities impact treatment tolerance. Methods: We utilized a cohort of 1345 mCRC patients enrolled in CALGB/SWOG 80405, a multicenter phase III trial of fluorouracil/leucovorin + oxaliplatin (FOLFOX) or irinotecan (FOLFIRI) plus bevacizumab, cetuximab or both. Endpoints were overall survival (OS), progression-free survival (PFS), and grade ≥ 3 toxicities assessed using NCI CTCAE v.3.0. Participants completed a questionnaire, including a modified Charlson Comorbidity Index. Adjusted Cox and logistic regression models tested associations of comorbidities and age on the endpoints. Results: In CALGB/SWOG 80405, 1095 (81%) subjects were < 70 years and >70 250 (19%). Presence of ≥1 comorbidity was not significantly associated with either OS (HR 1.10, 95% CI 0.96-1.25) or PFS (HR 1.03, 95% CI 0.91-1.16). Compared to subjects <70 with no comorbidities, OS was non-significantly inferior for ≥70 with no comorbidities (HR 1.21, 95% CI 0.98-1.49) and significantly inferior for ≥70 with at least one comorbidity (HR 1.51, 95% CI 1.22-1.86). There were no significant associations or interactions between age or comorbidity with PFS. Comorbidities were not associated with treatment-related toxicities. Age ≥ 70 was associated with greater risk of grade ≥ 3 toxicities (OR 2.15, 95% CI 1.50-3.09, p < 0.001). Conclusions: Among participants in a clinical trial of combination chemotherapy for mCRC, presence of older age with comorbidities was associated with worse OS but not PFS. The association of age with toxicity suggests additional factors of care should be measured in clinical trials.Item Association of Coffee Intake With Survival in Patients With Advanced or Metastatic Colorectal Cancer(American Medical Association, 2020-11-01) Mackintosh, Christopher; Yuan, Chen; Ou, Fang-Shu; Zhang, Sui; Niedzwiecki, Donna; Chang, I-Wen; O’Neil, Bert H.; Mullen, Brian C.; Lenz, Heinz-Josef; Blanke, Charles D.; Venook, Alan P.; Mayer, Robert J.; Fuchs, Charles S.; Innocenti, Federico; Nixon, Andrew B.; Goldberg, Richard M.; O’Reilly, Eileen M.; Meyerhardt, Jeffrey A.; Ng, Kimmie; Medicine, School of MedicineImportance: 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.Item Association of Diet Quality With Survival Among People With Metastatic Colorectal Cancer in the Cancer and Leukemia B and Southwest Oncology Group 80405 Trial(AMA, 2020-10-30) Van Blarigan, Erin L.; Zhang, Sui; Ou, Fang-Shu; Venlo, Alan; Ng, Kimmie; Atreya, Chloe; Van Loon, Katherine; Niedzwiecki, Donna; Giovannucci, Edward; Wolfe, Eric G.; Lenz, Heinz-Josef; Innocenti, Federico; O'Neil, Bert H.; Shaw, James E.; Polite, Blase N.; Hochster, Howard S.; Atkins, James N.; Goldberg, Richard M.; Mayer, Robert J.; Blanke, Charles D.; O'Reilly, Eileen M.; Fuchs, Charles S.; Meyerhardt, Jeffrey A.; Medicine, School of MedicineImportance: Diet has been associated with survival in patients with stage I to III colorectal cancer, but data on patients with metastatic colorectal cancer are limited. Objective: To examine the association between diet quality and overall survival among individuals with metastatic colorectal cancer. Design, Setting, and Participants: This was a prospective cohort study of patients with metastatic colorectal cancer who were enrolled in the Cancer and Leukemia Group B (Alliance) and Southwest Oncology Group 80405 trial between October 27, 2005, and February 29, 2012, and followed up through January 2018. Exposures: Participants completed a validated food frequency questionnaire within 4 weeks after initiation of first-line treatment for metastatic colorectal cancer. Diets were categorized according to the Alternative Healthy Eating Index (AHEI), Alternate Mediterranean Diet (AMED) score, Dietary Approaches to Stop Hypertension (DASH) score, and Western and prudent dietary patterns derived using principal component analysis. Participants were categorized into sex-specific quintiles. Main Outcomes and Measures: Multivariable hazard ratios (HRs) and 95% CIs for overall survival. Results: In this cohort study of 1284 individuals with metastatic colorectal cancer, the median age was 59 (interquartile range [IQR]: 51-68) years, median body mass index was 27.2 (IQR, 24.1-31.4), 521 (41%) were female, and 1102 (86%) were White. There were 1100 deaths during a median follow-up of 73 months (IQR, 64-87 months). We observed an inverse association between the AMED score and risk of death (HR quintile 5 vs quintile 1, 0.83; 95% CI, 0.67-1.04; P = .04 for trend), but the point estimates were not statistically significant. None of the other diet scores or patterns were associated with overall survival. Conclusions and Relevance: In this prospective analysis of patients with metastatic colorectal cancer, diet quality assessed at initiation of first-line treatment for metastatic disease was not associated with overall survival.Item Calcium Intake and Risk of Colorectal Cancer According to Tumor-infiltrating T Cells(AACR, 2019-05) Yang, Wanshui; Liu, Li; Keum, NaNa; Qian, Zhi Rong; Nowak, Jonathan A.; Hamada, Tsuyoshi; Song, Mingyang; Cao, Yin; Nosho, Katsuhiko; Smith-Warner, Stephanie A.; Zhang, Sui; Masugi, Yohei; Ng, Kimmie; Kosumi, Keisuke; Ma, Yanan; Garrett, Wendy S.; Wang, Molin; Nan, Hongmei; Giannakis, Marios; Meyerhardt, Jeffrey A.; Chan, Andrew T.; Fuchs, Charles S.; Nishihara, Reiko; Wu, Kana; Giovannucci, Edward L.; Ogino, Shuji; Zhang, Xuehong; Epidemiology, School of Public HealthCalcium intake has been associated with a lower risk of colorectal cancer. Calcium signaling may enhance T-cell proliferation and differentiation, and contribute to T-cell–mediated antitumor immunity. In this prospective cohort study, we investigated the association between calcium intake and colorectal cancer risk according to tumor immunity status to provide additional insights into the role of calcium in colorectal carcinogenesis. The densities of tumor-infiltrating T-cell subsets [CD3+, CD8+, CD45RO (PTPRC)+, or FOXP3+ cell] were assessed using IHC and computer-assisted image analysis in 736 cancer cases that developed among 136,249 individuals in two cohorts. HRs and 95% confidence intervals (CI) were calculated using Cox proportional hazards regression. Total calcium intake was associated with a multivariable HR of 0.55 (comparing ≥1,200 vs. <600 mg/day; 95% CI, 0.36–0.84; Ptrend = 0.002) for CD8+ T-cell–low but not for CD8+ T-cell–high tumors (HR = 1.02; 95% CI, 0.67–1.55; Ptrend = 0.47). Similarly, the corresponding HRs (95% CIs) for calcium for low versus high T-cell–infiltrated tumors were 0.63 (0.42–0.94; Ptrend = 0.01) and 0.89 (0.58–1.35; Ptrend = 0.20) for CD3+; 0.58 (0.39–0.87; Ptrend = 0.006) and 1.04 (0.69–1.58; Ptrend = 0.54) for CD45RO+; and 0.56 (0.36–0.85; Ptrend = 0.006) and 1.10 (0.72–1.67; Ptrend = 0.47) for FOXP3+, although the differences by subtypes defined by T-cell density were not statistically significant. These potential differential associations generally appeared consistent regardless of sex, source of calcium intake, tumor location, and tumor microsatellite instability status. Our findings suggest a possible role of calcium in cancer immunoprevention via modulation of T-cell function.Item Delphi Initiative for Early-Onset Colorectal Cancer (DIRECt) International Management Guidelines(Elsevier, 2023) Cavestro, Giulia Martina; Mannucci, Alessandro; Balaguer, Francesc; Hampel, Heather; Kupfer, Sonia S.; Repici, Alessandro; Sartore-Bianchi, Andrea; Seppälä, Toni T.; Valentini, Vincenzo; Boland, Clement Richard; Brand, Randall E.; Buffart, Tineke E.; Burke, Carol A.; Caccialanza, Riccardo; Cannizzaro, Renato; Cascinu, Stefano; Cercek, Andrea; Crosbie, Emma J.; Danese, Silvio; Dekker, Evelien; Daca-Alvarez, Maria; Deni, Francesco; Dominguez-Valentin, Mev; Eng, Cathy; Goel, Ajay; Guillem, Josè G.; Houwen, Britt B. S. L.; Kahi, Charles; Kalady, Matthew F.; Kastrinos, Fay; Kühn, Florian; Laghi, Luigi; Latchford, Andrew; Liska, David; Lynch, Patrick; Malesci, Alberto; Mauri, Gianluca; Meldolesi, Elisa; Møller, Pål; Monahan, Kevin J.; Möslein, Gabriela; Murphy, Caitlin C.; Nass, Karlijn; Ng, Kimmie; Oliani, Cristina; Papaleo, Enrico; Patel, Swati G.; Puzzono, Marta; Remo, Andrea; Ricciardiello, Luigi; Ripamonti, Carla Ida; Siena, Salvatore; Singh, Satish K.; Stadler, Zsofia K.; Stanich, Peter P.; Syngal, Sapna; Turi, Stefano; Urso, Emanuele Damiano; Valle, Laura; Vanni, Valeria Stella; Vilar, Eduardo; Vitellaro, Marco; You, Yi-Qian Nancy; Yurgelun, Matthew B.; Zuppardo, Raffaella Alessia; Stoffel, Elena M.; Associazione Italiana Familiarità Ereditarietà Tumori; Collaborative Group of the Americas on Inherited Gastrointestinal Cancer; European Hereditary Tumour Group; International Society for Gastrointestinal Hereditary Tumours; Medicine, School of MedicineBackground & aims: Patients with early-onset colorectal cancer (eoCRC) are managed according to guidelines that are not age-specific. A multidisciplinary international group (DIRECt), composed of 69 experts, was convened to develop the first evidence-based consensus recommendations for eoCRC. Methods: After reviewing the published literature, a Delphi methodology was used to draft and respond to clinically relevant questions. Each statement underwent 3 rounds of voting and reached a consensus level of agreement of ≥80%. Results: The DIRECt group produced 31 statements in 7 areas of interest: diagnosis, risk factors, genetics, pathology-oncology, endoscopy, therapy, and supportive care. There was strong consensus that all individuals younger than 50 should undergo CRC risk stratification and prompt symptom assessment. All newly diagnosed eoCRC patients should receive germline genetic testing, ideally before surgery. On the basis of current evidence, endoscopic, surgical, and oncologic treatment of eoCRC should not differ from later-onset CRC, except for individuals with pathogenic or likely pathogenic germline variants. The evidence on chemotherapy is not sufficient to recommend changes to established therapeutic protocols. Fertility preservation and sexual health are important to address in eoCRC survivors. The DIRECt group highlighted areas with knowledge gaps that should be prioritized in future research efforts, including age at first screening for the general population, use of fecal immunochemical tests, chemotherapy, endoscopic therapy, and post-treatment surveillance for eoCRC patients. Conclusions: The DIRECt group produced the first consensus recommendations on eoCRC. All statements should be considered together with the accompanying comments and literature reviews. We highlighted areas where research should be prioritized. These guidelines represent a useful tool for clinicians caring for patients with eoCRC.Item Diabetes and Clinical Outcome in Patients With Metastatic Colorectal Cancer: CALGB 80405 (Alliance)(Oxford University Press, 2020-02) Brown, Justin C.; Zhang, Sui; Ou, Fang-Shu; Venook, Alan P.; Niedzwiecki, Donna; Heinz-Josef Lenz, Heinz-Josef; Innocenti, Federico; O’Neil, Bert H.; Shaw, James E.; Polite, Blase N.; Denlinger, Crystal S.; Atkins, James N.; Goldberg, Richard M.; Ng, Kimmie; Mayer, Robert J.; Blanke, Charles D.; O’Reilly, Eileen M.; Fuchs, Charles S.; Meyerhardt, Jeffrey A.; Medicine, School of MedicineBackground Diabetes is a prognostic factor for some malignancies, but its association with outcome in patients with advanced or metastatic colorectal cancer (CRC) is less clear. Methods This cohort study was nested within a randomized trial of first-line chemotherapy and bevacizumab and/or cetuximab for advanced or metastatic CRC. Patients were enrolled at 508 community and academic centers throughout the National Clinical Trials Network. The primary exposure was physician-documented diabetes at the time of enrollment. The primary endpoint was overall survival (OS); secondary endpoints were progression-free survival (PFS) and adverse events. Tests of statistical significance were two-sided. Results Among 2326 patients, 378 (16.3%) had diabetes. The median follow-up time was 6.0 years. We observed 1973 OS events and 2173 PFS events. The median time to an OS event was 22.7 months among those with diabetes and 27.1 months among those without diabetes (HR = 1.27, 95% CI = 1.13 to 1.44; P < .001). The median time to a PFS event was 9.7 months among those with diabetes and 10.8 months among those without diabetes (HR = 1.16, 95% CI = 1.03 to 1.30; P = .02). Patients with diabetes were more likely to experience no less than grade 3 hypertension (8.1% vs 4.4%; P = .054) but were not more likely to experience other adverse events, including neuropathy. Conclusions Diabetes is associated with an increased risk of mortality and tumor progression in patients with advanced or metastatic CRC. Patients with diabetes tolerate first-line treatment with chemotherapy and monoclonal antibodies similarly to patients without diabetes.Item Lead-Time Trajectory of CA19-9 as an Anchor Marker for Pancreatic Cancer Early Detection(Elsevier, 2021) Fahrmann, Johannes F.; Schmidt, C. Max; Mao, Xiangying; Irajizad, Ehsan; Loftus, Maureen; Zhang, Jinming; Patel, Nikul; Vykoukal, Jody; Dennison, Jennifer B.; Long, James P.; Do, Kim-Anh; Zhang, Jianjun; Chabot, John A.; Kluger, Michael D.; Kastrinos, Fay; Brais, Lauren; Babic, Ana; Jajoo, Kunal; Lee, Linda S.; Clancy, Thomas E.; Ng, Kimmie; Bullock, Andrea; Genkinger, Jeanine; Yip-Schneider, Michele T.; Maitra, Anirban; Wolpin, Brian M.; Hanash, Samir; Surgery, School of MedicineBackground & Aims There is substantial interest in liquid biopsy approaches for cancer early detection among subjects at risk, using multi-marker panels. CA19-9 is an established circulating biomarker for pancreatic cancer; however, its relevance for pancreatic cancer early detection or for monitoring subjects at risk has not been established. Methods CA19-9 levels were assessed in blinded sera from 175 subjects collected up to 5 years before diagnosis of pancreatic cancer and from 875 matched controls from the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial. For comparison of performance, CA19-9 was assayed in blinded independent sets of samples collected at diagnosis from 129 subjects with resectable pancreatic cancer and 275 controls (100 healthy subjects; 50 with chronic pancreatitis; and 125 with noncancerous pancreatic cysts). The complementary value of 2 additional protein markers, TIMP1 and LRG1, was determined. Results In the PLCO cohort, levels of CA19-9 increased exponentially starting at 2 years before diagnosis with sensitivities reaching 60% at 99% specificity within 0 to 6 months before diagnosis for all cases and 50% at 99% specificity for cases diagnosed with early-stage disease. Performance was comparable for distinguishing newly diagnosed cases with resectable pancreatic cancer from healthy controls (64% sensitivity at 99% specificity). Comparison of resectable pancreatic cancer cases to subjects with chronic pancreatitis yielded 46% sensitivity at 99% specificity and for subjects with noncancerous cysts, 30% sensitivity at 99% specificity. For prediagnostic cases below cutoff value for CA19-9, the combination with LRG1 and TIMP1 yielded an increment of 13.2% in sensitivity at 99% specificity ( P = .031) in identifying cases diagnosed within 1 year of blood collection. Conclusion CA19-9 can serve as an anchor marker for pancreatic cancer early detection applications.Item Plasma 25-Hydroxyvitamin D Levels and Survival in Patients with Advanced or Metastatic Colorectal Cancer: Findings from CALGB/SWOG 80405 (Alliance)(American Association for Cancer Research, 2019-12-15) Yuan, Chen; Sato, Kaori; Hollis, Bruce W.; Zhang, Sui; Niedzwiecki, Donna; Ou, Fang-Shu; Chang, I.-Wen; O'Neil, Bert H.; Innocenti, Federico; Lenz, Heinz-Josef; Blanke, Charles D.; Goldberg, Richard M.; Venook, Alan P.; Mayer, Robert J.; Fuchs, Charles S.; MeyerhardtMeyerhardt, Jeffrey A.; Ng, Kimmie; Medicine, School of MedicinePurpose: Previous studies have suggested that higher circulating 25-hydroxyvitamin D [25(OH)D] levels are associated with decreased colorectal cancer (CRC) 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 CRC. Experimental design: We prospectively collected blood samples in 1,041 patients with previously untreated advanced or metastatic CRC 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 to <30 ng/mL). Higher 25(OH)D levels were associated with an improvement in OS and PFS (Ptrend=0.0009 and 0.03, respectively). Compared to 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 to 0.83) for OS and 0.81 (95% CI, 0.66 to 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 CRC, higher plasma 25(OH)D levels were associated with improved OS and PFS. Clinical trials assessing the benefit of vitamin D supplementation in CRC patients are warranted.
