Abstract Introduction Tobacco use can adversely affect cancer treatment outcomes, yet routine assessment has not been fully incorporated into oncology clinical trials. In 2012, rates of tobacco use assessment in actively accruing National Cancer Institute (NCI) trials were < 30% at enrollment and < 5% during follow-up, prompting efforts by the NCI and major oncology associations to promote and standardize tobacco assessment in oncology research and practice (including development of the Cancer Patient Tobacco Use Questionnaire [C-TUQ]). This study was conducted to re-examine assessment patterns in 2022 (including utilization of the C-TUQ) and evaluate progress. Aims and Methods Protocols and forms from 144 actively accruing (as of December 2022) NCI National Clinical Trials Network (NCTN) trials were evaluated using a standardized coding instrument. Results Of 144 trials, 49.3% assessed tobacco use at enrollment (43.8% measured cigarettes, 14.8% e-cigarettes, and ≤ 12.5% other tobacco products). Approximately 20.8% used at least one C-TUQ question, but only 3.5% used all four core items. Few measured second-hand smoke exposure (3.5%) or quit interest (2.8%). At follow-up, 8.3% assessed any form of tobacco use. Assessment rates were higher in smoking-related cancer trials. Conclusions Almost half of the accruing trials did not measure any tobacco use and fewer used the C-TUQ. There was a ≥ 70% increase in tobacco use assessment at enrollment and follow-up compared to 2012, an improvement with room for further enhancement. Standardized tobacco use information enhances investigators’ ability to estimate cancer treatment efficacy, offer equitable cessation support, and accurately understand the impact of tobacco use on treatment outcomes. Implications In 2012, few (< 30%) cancer clinical trials evaluated tobacco use at enrollment and < 5% did so during follow-up, prompting efforts to promote and standardize tobacco assessment in oncology research and practice (including the development of the Cancer Patient Tobacco Use Questionnaire [C-TUQ]). The present study builds on this foundational paper and finds an overall increase in tobacco use assessment with room for improvement: 49.3% of trials in 2022 assessed tobacco use at enrollment and 8.3% did so during follow-up. About 20.8% used at least one C-TUQ question, highlighting that tobacco use assessment is not yet fully incorporated into oncology clinical trials.

Inadequate light penetration in tissues restricts photodynamic therapy to treating only superficial tumors. To enable x-ray–excited photodynamic therapy (XPDT) that targets deep-seated tumors, we synthesized a nanoscintillator-photosensitizer complex containing 5% Eu-doped Y 2 O 3 fluorescing at 611 nanometers and decorated with SiO 2 containing the scintillation-coupled photosensitizer methylene blue and a polyethylene glycol coating [PEGylated Y 2 O 3 :Eu@SiO 2 -methylene blue (pYSM)]. When irradiated, pYSMs generate singlet oxygen species in vitro, causing cytotoxicity with hallmarks of immunogenic cell death (calreticulin translocation to the cell membrane). Intravenously administered pYSMs home passively to pancreatic tumor xenografts and, upon 10 gray irradiation, cause significant tumor regression ( P < 0.01). On combining XPDT with anti-PD1 immunotherapy, a distant nonirradiated tumor also regresses via an increase in intratumoral activated CD8 + cytotoxic T cells. Collectively, we advance a systemically delivered XPDT strategy that mediates an antitumor effect in both irradiated and nonirradiated (abscopal) tumors when coupled with immunotherapy, converting an immunologically “cold” tumor to an immunologically “hot” tumor.

Abstract: A 49-year-old short-board goofy-stance competitive surfer presented with a 3-month history of bilateral, left foot pain associated with tender soft tissue plantar nodules. Magnetic resonance imaging of the left foot revealed foci of fibrotic tissue within the subcutaneous tissue adjacent to the first and fifth metatarsophalangeal joints compatible with surfers' knots . The patient underwent conservative treatment with oral ibuprofen as needed before competitions, topical diclofenac gel, wide toe box shoes, and use of a double-thick traction pad on his surfboard to alleviate the friction between the metatarsophalangeal joints of his left foot and the surfboard. He reported improvement of symptoms and full return to surfing at 8-month follow-up. We present a case of surfers' knots overlying the left first and fifth metatarsophalangeal joints of a male competitive surfer and highlight recommendations for successful conservative treatment options for symptomatic athletes.
