Implementation of a comprehensive smoking cessation program in cancer care.

Background: Quitting smoking after a cancer diagnosis maximizes treatment-related effects, improves prognosis, and enhances quality of life. However, smoking cessation (sc) services are not routinely integrated into cancer care. The Princess Margaret Cancer Centre implemented a digitally-based sc program in oncology, leveraging an e-referral system (cease) to screen all new ambulatory patients, provide tailored education and advice on quitting, and facilitate referrals. Methods: We adopted the Framework for Managing eHealth Change to guide implementation of the sc program by integrating 6 key elements: governance and leadership, stakeholder engagement, communication, workflow analysis and integration, monitoring and evaluation, and training and education. Results: Incorporating elements of the Framework, we used extensive stakeholder engagement and strategic partnerships to establish a sc program with organizational and provincial accountability. Existing electronic patient-reported assessments were changed to integrate cease. Clinic audits and staff engagement allowed for analysis of workflow, ongoing monitoring and evaluation that aided in establishing a communication strategy, and development of cancer-specific education for patients and health care providers. From April 2016 to March 2018, 22,137 new patients were eligible for screening. Among those new patients, 13,617 (62%) were screened, with 1382 (10%) being current smokers and 532 (4%) having recently quit (within 6 months). Of the current smokers and those who had recently quit, all were advised to quit or to stay smoke-free, and 380 (20%) accepted referral to a sc counselling service. Conclusions: Here, we provide a comprehensive practice blueprint for the implementation of digitally based sc programs as a standard of care within comprehensive cancer centres with high patient volumes.

Effects of Curcumin on Squamous Cell Carcinoma of Tongue: An In Vitro Study.

BACKGROUND: The Squamous Cell Carcinoma of the Tongue (TSCC) is the most frequent cancer of oral cavity often characterized by poor prognosis. Conventional therapies are not very efficient and often may cause serious side effects. In this context, introduction of natural substances as possible adjuvant in the treatment and prevention of cancer is becoming a relevant topic. In fact, curcumin has been used for decades in Chinese traditional medicine for its beneficial effects. Curcumin has anticancer properties in many tumors however, its action on the tongue carcinoma is not entirely clear and many other investigations are necessary. OBJECTIVE: Curcumin seems to be a good adjuvant in the treatment of head and neck tumors. However, these studies are generic and there are not many specific studies on TSCC, the most frequent and most aggressive cancer of the head-neck region. Our goal is to demonstrate its effectiveness also for TSCC. METHODS: In this study, we evaluated the effects of curcumin on TSCC cells using different concentrations (1, 5, 10, 20 and 50 µM) and 3 different treatment times (24, 48 and 72 hours). The inhibition of adhesion, proliferation, viability, migration and apoptosis was studied. RESULTS: IC50 value of curcumin is about 10 µM and there have been inhibitory effects even for treatments at low concentrations. Curcumin reduces migration and progression of TSCC cells and it promotes apoptosis and inhibits tumorigenesis. CONCLUSIONS: These results suggest the possible use of curcumin as an anti-cancer agent in TSCC. However, in vivo studies are needed to confirm these effects and overcome its low bioavailability.

Trends, practice patterns and underuse of surgery in the treatment of early stage small cell lung cancer.

BACKGROUND: Practice guidelines from the National Comprehensive Cancer Network and the American Society of Clinical Oncology recommend pathologic mediastinal staging and surgical resection for patients with clinically node-negative T1/T2 small cell lung cancer (SCLC), but the extent to which surgery is used is unknown. We sought to assess trends and practice patterns in the use of surgery for SCLC. METHODS: T1 or T2N0M0 SCLC cases were identified in the National Cancer Database (NCDB), 2004-2013. Characteristics of patients undergoing resection were analyzed. Hierarchical logistic regression was used to identify individual and hospital-level predictors of receipt of surgery, adjusting for clinical, demographic and facility characteristics. Trends in resection rates were analyzed over the study period. FINDINGS: 9740 patients were identified with clinical T1 or T2 N0M0 SCLC. Of these, 2210 underwent surgery (22.7%), with 1421 (64.3%) undergoing lobectomy, 739 (33.4%) sublobar resections and 50 (2.3%) pneumonectomies. After adjustment, Medicaid patients were less likely to receive surgery (OR0.65 95% CI 0.48-0.89, p=0.006), as were those with T2 tumors (OR0.25 CI0.22-0.29, p<0.0001). Academic facilities were more likely to resect eligible patients (OR 1.90 CI1.45-2.49, p<0.0001). Between 2004 and 2013, resection rates more than doubled from 9.1% to 21.7%. Overall, 68.7% of patients were not offered surgery despite having no identifiable contraindication. In patients not receiving surgery, only 7% underwent pathologic mediastinal staging. INTERPRETATION: Rates of resection are increasing, but two thirds of potentially eligible patients fail to undergo surgery. Further study is required to address the lack of concordance between guidelines and practice.
