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 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 Body Mass Index and Weight Loss in Metastatic Colorectal Cancer in CALGB (Alliance)/SWOG 80405(Oxford University Press, 2020-03-31) Guercio, Brendan J.; Zhang, Sui; Venook, Alan P.; Ou, Fang-Shu; Niedzwiecki, Donna; Lenz, Heinz-Josef; Innocenti, Federico; Mullen, Brian C.; O’Neil, Bert H.; Shaw, James E.; Polite, Blase N.; Hochster, Howard S.; Atkins, James N.; Goldberg, Richard M.; Brown, Justin C.; O’Reilly, Eileen M.; Mayer, Robert J.; Blanke, Charles D.; Fuchs, Charles S.; Meyerhardt, Jeffrey A.; Medicine, School of MedicineBackground: In nonmetastatic colorectal cancer, overweight and mild-to-moderately obese patients experience improved outcomes compared with other patients. Obesity's influence on advanced or metastatic colorectal cancer (mCRC) is relatively unexplored. Methods: We conducted a prospective body mass index (BMI) companion study in Cancer and Leukemia Group B (now Alliance)/SWOG 80405, a phase III metastatic colorectal cancer (mCRC) treatment trial. BMI was measured at trial registration. Primary and secondary endpoints were overall and progression-free survival, respectively. To minimize confounding by poor and rapidly declining health, we used Cox proportional hazards regression to adjust for known prognostic factors, comorbidities, physical activity, and weight loss during the 6 months prior to study entry. We also examined weight loss prior to enrollment as an independent predictor of patient outcome. All statistical tests were two-sided. Results: Among 2323 patients with mCRC, there were no statistically significant associations between BMI and overall or progression-free survival (adjusted P trend = .12 and .40, respectively). Weight loss during the 6 months prior to study entry was associated with shorter overall and progression-free survival; compared with individuals with stable weight ±4.9%, individuals with weight loss greater than 15% experienced an adjusted hazard ratio of 1.52 for all-cause mortality (95% confidence interval [CI] = 1.26 to 1.84; P trend < .001) and of 1.23 for disease progression or death (95% CI = 1.02 to 1.47; P trend = .006). Conclusions: In this prospective study of patients with mCRC, BMI at time of first-line chemotherapy initiation was not associated with patient outcome. Weight loss prior to study entry was associated with increased risk of patient mortality and disease progression.Item Clinical Assessment of 5-Fluorouracil/Leucovorin, Nab-Paclitaxel, and Irinotecan (FOLFIRABRAX) in Untreated Patients with Gastrointestinal Cancer Using UGT1A1 Genotype–Guided Dosing(American Association for Cancer Research, 2020-01-01) Joshi, Smita S.; Catenacci, Daniel V. T.; Karrison, Theodore G.; Peterson, Jaclyn D.; Zalupski, Mark M.; Sehdev, Amikar; Wade, James; Sadiq, Ahad; Picozzi, Vincent J.; Amico, Andrea; Marsh, Robert; Kozloff, Mark F.; Polite, Blase N.; Kindler, Hedy L.; Sharma, Manish R.; Medicine, School of MedicinePurpose: 5-fluorouracil/leucovorin, irinotecan, and nab-paclitaxel are all active agents in gastrointestinal cancers; the combination, FOLFIRABRAX, has not been previously evaluated. UDP Glucuronosyltransferase 1A1 (UGT1A1) clears SN-38, the active metabolite of irinotecan. UGT1A1*28 polymorphism reduces UGT1A1 enzymatic activity and predisposes to toxicity. We performed a trial to assess the safety and tolerability of FOLFIRABRAX with UGT1A1 genotype-guided dosing of irinotecan. Experimental Design: Patients with previously untreated, advanced gastrointestinal cancers received FOLFIRABRAX with prophylactic pegfilgrastim every 14 days. UGT1A1 *1/*1, *1/*28, and *28/*28 patients received initial irinotecan doses of 180, 135, and 90 mg/m2, respectively. 5-FU 2400 mg/m2 over 46 hours, leucovorin 400 mg/m2, and nab-paclitaxel 125 mg/m2 were administered. Doses were deemed tolerable if the dose limiting toxicity (DLT) rate during cycle 1 was ≤35% in each genotype group. DLTs were monitored using a sequential procedure. Results: Fifty patients enrolled: 30 pancreatic, 9 biliary tract, 6 gastroesophageal, and 5 others. DLTs occurred in 5/23 (22%) *1/*1 patients, 1/19 (5%) *1/*28 patients, and 0/7 *28/*28 patients. DLTs were all grade 3: diarrhea (3 patients), nausea (2 patients), and febrile neutropenia (1 patient). The overall response rate was 31%. Response rates in pancreatic, gastroesophageal, and biliary tract cancers were 34%, 50%, and 11%, respectively. Eighteen patients (36%) received therapy for at least 24 weeks. Conclusion: FOLFIRABRAX with genotype-guided dosing of irinotecan is tolerable in patients with advanced gastrointestinal cancer and UGT1A1*1*1 or UGT1A1*1*28 genotypes. Too few *28/*28 patients were enrolled to provide conclusive results. Responses occurred across multiple tumor types.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 IGF-Binding Proteins, Adiponectin, and Survival in Metastatic Colorectal Cancer: Results From CALGB (Alliance)/SWOG 80405(Oxford University Press, 2020-08-27) Guercio, Brendan J.; Zhang, Sui; Ou, Fang-Shu; Venook, Alan P.; Niedzwiecki, Donna; Lenz, Heinz-Josef; Innocenti, Federico; Pollak, Michael N.; Nixon, Andrew B.; Mullen, Brian C.; O'Neil, Bert H.; Shaw, James E.; Polite, Blase N.; Benson, Al Bowen, III.; Atkins, James N.; Goldberg, Richard M.; Brown, Justin C.; O'Reilly, Eileen M.; Mayer, Robert J.; Blanke, Charles D.; Fuchs, Charles S.; Meyerhardt, Jeffrey A.; Medicine, School of MedicineBackground: Energy balance-related biomarkers are associated with risk and prognosis of various malignancies. Their relationship to survival in metastatic colorectal cancer (mCRC) requires further study. Methods: Baseline plasma insulin-like growth factor (IGF)-1, IGF-binding protein (IGFBP)-3, IGFBP-7, C-peptide, and adiponectin were measured at time of trial registration in a prospective cohort of patients with mCRC participating in a National Cancer Institute-sponsored trial of first-line systemic therapy. We used Cox proportional hazards regression to adjust for confounders and examine associations of each biomarker with overall survival (OS) and progression-free survival (PFS). P values are 2-sided. Results: Median follow-up for 1086 patients was 6.2 years. Compared with patients in the lowest IGFBP-3 quintile, patients in the highest IGFBP-3 quintile experienced an adjusted hazard ratio (HR) for OS of 0.57 (95% confidence interval [CI] = 0.42 to 0.78; P nonlinearity < .001) and for PFS of 0.61 (95% CI = 0.45 to 0.82; P trend = .003). Compared with patients in the lowest IGFBP-7 quintile, patients in the highest IGFBP-7 quintile experienced an adjusted hazard ratio for OS of 1.60 (95% CI = 1.30 to 1.97; P trend < .001) and for PFS of 1.38 (95% CI = 1.13 to 1.69; P trend < .001). Plasma C-peptide and IGF-1 were not associated with patient outcomes. Adiponectin was not associated with OS; there was a nonlinear U-shaped association between adiponectin and PFS (P nonlinearity = .03). Conclusions: Among patients with mCRC, high plasma IGFBP-3 and low IGFBP-7 were associated with longer OS and PFS. Extreme levels of adiponectin were associated with shorter PFS. These findings suggest potential avenues for prognostic and therapeutic innovation.Item Management of colorectal cancer during the COVID‐19 pandemic: Recommendations from a statewide multidisciplinary cancer collaborative(Wiley, 2022) Brajcich, Brian C.; Benson, Al B.; Gantt, Gerald, Jr.; Eng, Oliver S.; Marsh, Robert W.; Mulcahy, Mary F.; Polite, Blase N.; Shogan, Benjamin D.; Yang, Anthony D.; Merkow, Ryan P.; Surgery, School of MedicineCOVID-19 has resulted in significant disruptions in cancer care. The Illinois Cancer Collaborative (ILCC), a statewide multidisciplinary cancer collaborative, has developed expert recommendations for triage and management of colorectal cancer when disruptions occur in usual care. Such recommendations would be applicable to future outbreaks of COVID-19 or other large-scale disruptions in cancer care.Item A pharmacodynamic study of sirolimus and metformin in patients with advanced solid tumors(Springer, 2018-08) Sehdev, Amikar; Karrison, Theodore; Zha, Yuanyuan; Janisch, Linda; Turcich, Michelle; Cohen, Ezra E. W.; Maitland, Michael; Polite, Blase N.; Gajewski, Thomas F.; Salgia, Ravi; Pinto, Navin; Bissonnette, Marc B.; Fleming, Gini F.; Ratain, Mark J.; Sharma, Manish R.; Medicine, School of MedicineBackground Sirolimus is a mammalian target of rapamycin (mTOR) inhibitor. Metformin may potentiate mTOR inhibition by sirolimus while mitigating its adverse effects. We conducted a pilot study to test this hypothesis. Methods Patients with advanced solid tumor were treated with sirolimus for 7 days followed by randomization to either sirolimus with metformin (Arm A) or sirolimus (Arm B) until day 21. From day 22 onwards, all patients received sirolimus and metformin. The primary aim was to compare the change in phospho-p70S6K (pp70S6K) in peripheral blood mononuclear cells (PBMC) from day 8 to day 22 using a two-sample t test. Secondary aims were objective response rate, toxicity, and other serum pharmacodynamic biomarkers (e.g., fasting glucose, triglycerides, insulin, C-peptide, IGF-1, IGF-1R, IGF-BP, and leptin). Results 24 patients were enrolled, with 18 evaluable for the primary endpoint. There was no significant difference in mean change in pp70S6K in arm A vs. arm B (− 0.12 vs. − 0.16; P = 0.64). Similarly, there were no significant differences in other serum pharmacodynamic biomarkers. There were no partial responses. There were no dose-limiting or unexpected toxicities. Conclusions Adding metformin to sirolimus, although well tolerated, was not associated with significant changes in pp70S6K in PBMC or other serum pharmacodynamic biomarkers. Impact: Combining metformin with sirolimus did not improve mTOR inhibition.
