Objective: Hookah smoking is a popular form of tobacco use on university campuses. This study documented use, attitudes, and knowledge of hookah smoking among college students. Participants: The sample included 943 university students recruited between February 2009 and January 2010. Respondents (M age = 20.02) included 376 males, 533 females, and 34 who did not report sex. Methods: An anonymous online questionnaire was completed by respondents. Results: In this sample, 42.9% of college students had tried hookah, and 40% of those individuals had used it in the past 30 days. Students perceived fewer negative consequences of hookah smoking compared with cigarette smoking. Age, sex, racial background, marijuana/cigarette use, and perceptions of side effects were significantly associated with hookah use. Conclusions: University students are misinformed regarding the health consequences of hookah smoking. Programs aimed at education, prevention, and intervention for hookah use are needed to address this growing public health concern.

Background: We report long-term outcomes of patients treated with primary radiotherapy (RT) or surgery and adjuvant RT for salivary gland malignancies. Materials and methods: From 1964 to 2012, 291 patients received primary RT (n = 67) or RT combined with surgery (n = 224). Results: The 5-, 10-, and 15-year local control, local-regional control, distant metastasis-free survival, cause-specific survival and overall survival rates were 82%, 77% and 73%; 77%, 72% and 67%; 74%, 70% and 70%; 70%, 59% and 54%; and 63%, 47% and 38%, respectively. Per multivariate analysis, combined surgery and RT and T stage impacted local control; overall stage and combined surgery and RT impacted local-regional control; overall stage impacted distant metastasis-free survival; and overall stage, node positivity, clinical nerve invasion, and surgery and RT impacted cause-specific and overall survival. Five percent of patients experienced grade 3 or worse toxicity. Conclusion: Combined surgery and RT improves local control, local-regional control, and cause-specific survival compared with primary RT for salivary tumors.

Anxiety and depression are disabling, underdiagnosed issues that affect the management of oncology patients. Until recently, there has been no standard protocol for screening and treating these ailments at our cancer centre. The purpose of this institutional review board-approved study was to analyse the implementation of a screening tool in our clinical workflow with the aim of screening over 90% of patients and increasing referrals to mental health services by 50%.

To evaluate the effectiveness of external-beam proton therapy (PT) on local control and survival in patients with skull-base chordoma. We reviewed the medical records of patients with skull-base chordoma treated with definitive or adjuvant high-dose PT and updated their follow-up when feasible. We assessed overall survival, disease-specific survival, local control, and freedom from distant metastasis. Radiotherapy toxicities were scored using the Common Terminology Criteria for Adverse Events, version 4.0. A total 112 patients were analyzed, of whom 105 (94%) received PT and 7 (6%) received combined proton-photon therapy between 2007 and 2019. Eighty-seven patients (78%) underwent a subtotal resection, 22 (20%) a gross total resection, and 3 (3%) a biopsy alone. The median radiotherapy dose was 73.8 Gy radiobiologic equivalent (GyRBE; range, 69.6-74.4). Ninety patients (80%) had gross disease at radiotherapy and 7 (6%) were treated for locally recurrent disease following surgery. Median follow-up was 4.4 years (range, 0.4-12.6); for living patients, it was 4.6 years (range, 0.4-12.6), and for deceased patients, 4.1 years (range, 1.2-11.2). At 5 years after radiotherapy, the actuarial overall survival, disease-specific survival, local control, and freedom from distant metastasis rates were 78% (n = 87), 83% (n = 93), 74% (n = 83), and 99% (n = 111), respectively. The median time to local progression was 2.4 years (range, 0.8-7). Local control and disease-specific survival by resection status was 95% versus 70% (P = 0.28) and 100% versus 80% (P = 0.06) for gross total, versus subtotal, resection or biopsy alone, respectively. There were no serious acute toxicities (grade ≥ 3) related to radiotherapy. High-dose PT alone or after surgical resection for skull-base chordoma reaffirms the favorable 5-year actuarial local control rate compared with conventional techniques with acceptable late-complication–free survival. Outcomes following gross total resection and adjuvant PT were excellent. Further follow-up of this cohort is necessary to better characterize long-term disease control and late toxicities.
