Article Synopsis
  • * New tobacco control services were introduced, including motivational counseling, clinician champions, and a patient-centered program called Personalized Pathways to Success (PPS) aimed at improving engagement and outcomes.
  • * Results showed increased lung cancer screenings, higher tobacco use assessments, and a notable 27.2% cessation rate, with the PPS program achieving 47% engagement and 38% self-reported abstinence at 3 months, particularly benefiting minority patients.

Purpose: Quitting smoking improves patients' clinical outcomes, yet smoking is not commonly addressed as part of cancer care. The Cancer Center Cessation Initiative (C3I) supports National Cancer Institute-designated cancer centers to integrate tobacco treatment programs (TTPs) into routine cancer care. C3I centers vary in size, implementation strategies used, and treatment approaches.

Purpose: Continued smoking after a cancer diagnosis is causally linked to cancer-specific and all-cause mortality. Additionally, smoking, in particular after a cancer diagnosis, increases risk for poor therapeutic outcomes, chronic disease and even COV19 infection.

Methods: In order to better understand and address continued smoking among cancer patients, this research applied geospatial mapping analysis to explore the potential association of dedicated smoke/vape shops density and smoking among cancer patients.

Background: We designed a process to increase tobacco cessation in an academic center and its widely distributed network community sites using clinical champions to overcome referral barriers.

Methods: In 2020 a needs assessment was performed across the City of Hope Medical Center and its 32 community treatment sites. We reviewed information science strategies to choose elements for our expanded tobacco control plan, focusing on distributed leadership with tobacco cessation champions.

Background: Patients requiring upper gastrointestinal surgery for benign oesophageal conditions are at nutrition risk before and after surgery. There is a dearth of published evidence guiding clinicians on effective collaboration with patients to mitigate perioperative nutritional challenges. We conducted a qualitative study aiming to explore patients' perioperative food, nutrition, and educational experiences to guide future care.

Tobacco products cause about 1 in 5 deaths premature deaths each year. With increased retailing of both tobacco and electronic nicotine delivery systems (ENDS) products, cancer centers such as City of Hope are prioritizing tobacco and ENDS control. Therefore, we conducted formative geospatial analyses of dedicated smoke and vape shops linked to neighborhood demographic characteristics.

Background: Federally Qualified Health Centers (FQHCs) serve minority and low-socioeconomic populations and provide care to high-risk smokers. These centers frequently experience barriers, including low provider and medical assistant (MA) knowledge around lung cancer screening (LCS). Subsequent low LCS referral rates by providers at FQHCs limit utilization of LCS in eligible, high-risk, underserved patients.

Tobacco smoke is a well-known carcinogen associated with multiple malignancies. Patients with cancer, as well as survivors, who continue to smoke are at a greater risk for poor cancer treatment outcomes. With the emergence of the COVID-19 pandemic, there is increased frequency and severity of the infection in patients with cancer.

Purpose: This study examined the predictors of health-related quality of life (HRQOL) and changes in HRQOL over a 1-year period among Chinese-American breast cancer survivors (BCS).

Methods: A two-wave longitudinal research design included participants from hospital-based cancer registries and community organizations in Los Angeles. Participants completed mailed questionnaires at baseline and 12-month follow-up.

Lung cancer is one of the deadliest and yet largely preventable neoplasms. Smoking cessation and lung cancer screening are effective yet underutilized lung cancer interventions. City of Hope Medical Center, a National Cancer Institute (NCI)- designated comprehensive cancer center, has 27 community cancer centers and has prioritized tobacco control and lung cancer screening throughout its network.

Protein can modulate the surgical stress response and postoperative catabolism. Enhanced Recovery After Surgery (ERAS) protocols are evidence-based care bundles that reduce morbidity. In this study, we compared protein adequacy as well as energy intakes, gut function, clinical outcomes, and how well nutritional variables predict length of hospital stay (LOS) in patients receiving ERAS protocols and conventional care.

Background: To address the fear of cancer recurrence (FCR) research gap, we used prospective data to explore FCR predictors and FCR associations with health-related quality of life among Asian-American breast cancer survivors (BCS).

Methods: A total of 208 diverse Asian-American BCS completed T1 survey, and 137 completed T2 survey after 1 year.

Results: Fear of cancer recurrence scores (range = 0-4) were 2.

Purpose: Randomized controlled trials have established that there is no benefit to withholding oral food and fluids from colorectal surgery patients postoperatively. The aim of this survey was to determine food preferences for the first postoperative meal and compare these with a traditional clear-fluid diet.

Methods: One hundred forty-five elective colorectal surgery patients were surveyed about their preferences for 35 common foods within 72 hours of surgery and their levels of nausea, hunger, and pain.
