Background/UNASSIGNED:Medical marijuana (MM) use is common among cancer patients, but relatively little is known about the usage patterns and efficacy of MM used by gynecologic cancer patients. Methods/UNASSIGNED:Demographic and clinical data were collected for gynecologic cancer patients prescribed MM between May 2016 and February 2019. The electronic medical record was used to query formulation prescribed, usage patterns, length of use, symptom relief, and side effect profile. Descriptive statistics were calculated. Results/UNASSIGNED:Of 45 gynecologic cancer patients prescribed MM, 89% were receiving chemotherapy; 56% were undergoing primary treatment. MM was used for a median of 5.2 months (range 0.6-25.4). Over 70% of patients reported improvement in nausea/vomiting, compared to 36% of patients using MM for pain relief (p = 0.02). Of 41 patients with follow-up information, 71% found MM improved at least one symptom. Conclusions/UNASSIGNED:Among a small sample of gynecologic cancer patients prescribed MM for symptom management, self-reported follow-up indicated symptom relief for the majority of patients and minimal therapy-related side effects. This data can prove useful for counseling gynecologic cancer patients on the efficacy and side effects of MM.

BACKGROUND/OBJECTIVES/OBJECTIVE:Use of cannabis is increasing in a variety of populations in the United States; however, few investigations about how and for what reasons cannabis is used in older populations exist. DESIGN/METHODS:Anonymous survey. SETTING/METHODS:Geriatrics clinic. PARTICIPANTS/METHODS:A total of 568 adults 65 years and older. INTERVENTION/METHODS:Not applicable. MEASUREMENTS/METHODS:Survey assessing characteristics of cannabis use. RESULTS:Approximately 15% (N = 83) of survey responders reported using cannabis within the past 3 years. Half (53%) reported using cannabis regularly on a daily or weekly basis, and reported using cannabidiol-only products (46%). The majority (78%) used cannabis for medical purposes only, with the most common targeted conditions/symptoms being pain/arthritis (73%), sleep disturbance (29%), anxiety (24%), and depression (17%). Just over three-quarters reported cannabis "somewhat" or "extremely" helpful in managing one of these conditions, with few adverse effects. Just over half obtained cannabis via a dispensary, and lotions (35%), tinctures (35%), and smoking (30%) were the most common administration forms. Most indicated family members (94%) knew about their cannabis use, about half reported their friends knew, and 41% reported their healthcare provider knowing. Sixty-one percent used cannabis for the first time as older adults (aged ≥61 years), and these users overall engaged in less risky use patterns (e.g., more likely to use for medical purposes, less likely to consume via smoking). CONCLUSION/CONCLUSIONS:Most older adults in the sample initiated cannabis use after the age of 60 years and used it primarily for medical purposes to treat pain, sleep disturbance, anxiety, and/or depression. Cannabis use by older adults is likely to increase due to medical need, favorable legalization, and attitudes.

PURPOSE/OBJECTIVE:Identification of lymph node (LN) metastasis in non-small cell lung cancer (NSCLC) is critical for disease staging and selection of therapeutic modalities. Sometimes it is not possible to obtain LN core tissue by endobronchial ultrasound-guided transbronchial needle aspirate (EBUS-TBNA), resulting in low diagnostic yield. MATERIALS AND METHODS/METHODS:In this study, 138 specimens were collected from 108 patients who underwent EBUS-TBNA under the suspicion of LN metastasis of NSCLC. Diagnostic yields of anti-CD45 and anti-methionyl-tRNA synthetase (MRS), immunofluorescent (IF) staining on cytology specimens were compared with those of conventional cytology and positron emission tomography-computed tomography (PET-CT). RESULTS:MRS was strongly expressed in NSCLC cells metastasized to LNs, but weakly expressed in cells at the periphery of the LN germinal center. The majority of cells were CD20 positive, although a few cells were either CD3 or CD14 positive, indicating that CD45 staining is required for discrimination of non-malignant LN constituent cells from NSCLC cells. When the diagnostic efficacy of MRS/CD45 IF staining was evaluated using 138 LN cellular aspirates from 108 patients through EBUS-TBNA, the sensitivity was 76.7% and specificity was 90.8%, whereas those of conventional cytology test were 71.8% and 100.0%, respectively. Combining the results of conventional cytology testing and those of PET-CT showed a sensitivity and specificity of 71.6% and 100%, and the addition of MRS/CD45 dual IF data to this combination increased sensitivity and specificity to 85.1% and 97.8%, respectively. CONCLUSION/CONCLUSIONS:MRS/CD45 dual IF staining showed good diagnostic performance and may be a good tool complementing conventional cytology test for determining LN metastasis of NSCLC.

BACKGROUND:Research on the patterns of use of medical cannabis among cancer patients is lacking. OBJECTIVE:To describe patterns of medical cannabis use by patients with cancer, and how patterns differ from patients without cancer. DESIGN/MEASUREMENTS/METHODS:We performed secondary data analysis using data from a medical cannabis licensee in New York State, analyzing demographic information, qualifying conditions, and symptoms, and the medical cannabis product used, including tetrahydrocannabinol (THC) to cannabidiol (CBD) ratios. SETTING/SUBJECTS/METHODS:Adults age ≥18 who used New York State medical cannabis licensee products between January 2016 and December 2017. RESULTS:There were a total of 11,590 individuals with 1990 (17.2%) having cancer who used at least one cannabis product. Patients with cancer using cannabis were older and more likely to be female. The most common qualifying symptom for both cancer and noncancer patients was severe or chronic pain. Cancer patients were more likely to use the sublingual tincture form of cannabis (n = 1098, 55.2%), while noncancer patients were more likely to use the vaporization form (n = 4222, 44.0%). Over time, across all patients, there was an increase in the THC daily dose by a factor of 0.20 mg/week, yielding a corresponding increase in the THC:CBD daily ratio. Compared with noncancer patients, these trends were not different in the cancer group for THC daily dose, but there were less pronounced increases in the THC:CBD daily ratio over time among cancer patients. CONCLUSIONS:Our study found some key differences in demographics and medical cannabis product use between patients with cancer and without cancer.

BACKGROUND:Dropped head syndrome is a potential late neurologic complication of radiation therapy in survivors of Hodgkin lymphoma. There is limited evidence for conservative management of this condition. OBJECTIVE:To discover patient utilization patterns of the commonly prescribed Headmaster Collar (cervical) in Hodgkin lymphoma survivors with radiation-induced dropped head syndrome. DESIGN/METHODS:Questionnaire-based retrospective observational study. SETTING/METHODS:Single-site academic cancer center. PATIENTS/METHODS:Twenty-six Hodgkin lymphoma survivors treated with radiation therapy involving the mantle who were prescribed a Headmaster Collar for dropped head syndrome. METHODS OR INTERVENTIONS/UNASSIGNED:Patients were interviewed by phone with a structured set of questions. MAIN OUTCOME MEASUREMENTS/METHODS:Compliance, patterns of use, individual modifications, and side effects of collar use. RESULTS:Although 58% of patients who were prescribed a Headmaster Collar eventually discontinued its use, 62% of all patients used the collar for more than 6 months. The majority of users wore the collar for up to 3 hours per day, usually for static seated activities. Thirty-eight percent of patients made personal modifications to their collar, most commonly the addition of extra padding. All but one patient had complaints about the collar, most commonly discomfort, rigidity, and confinement. CONCLUSIONS:The Headmaster Collar (cervical) is often utilized for a few hours a day, for longer than 6 months, to help with static seated activities. Insights from this study might help to improve future orthotic designs with better long-term compliance rates for the treatment of radiation-induced dropped head syndrome. LEVEL OF EVIDENCE/METHODS:IV.

In this needs assessment, gathered patient perceptions on how telemedicine video visits might influence their care. Patients in this study (n = 13) were all diagnosed with end-stage cancer and were receiving palliative care at an urban academic medical center. Interview themes addressed: 1. impact on patient's health management, 2. user experience, 3. technical issues and 4. cost and time. Ultimately, despite concerns over truncated physical exams and prescription limits, the majority of patients favored having the opportunity for telemedicine video visits, felt that the doctor-patient relationship would not suffer, had confidence in their or their surrogate's technical abilities to navigate the video visit, had privacy concerns on par with other technologies, had few cost concerns, and believed a video alternative to an in-person visit might increase access, save time as well as increase comfort and safety by avoiding a trip to the office. These results suggest potential for acceptance of video-based telemedicine by an urban population of oncology patients receiving palliative care.

INTRODUCTION: Lymphedema has long been considered a risk factor for median nerve compression at the wrist and carpal tunnel syndrome (CTS). This association is based on limited and poor quality data. We analyzed the association between lymphedema and CTS. METHODS: Breast cancer survivors with upper extremity lymphedema and electrophysiologically confirmed CTS were assessed retrospectively. The severity of lymphedema was graded using the National Institutes of Health Common Terminology Criteria for Adverse Events (CTCAE) v4.03. The severity of CTS was graded in accordance with accepted criteria. RESULTS: Nineteen patients (38 sides) met the criteria for analysis. There was no association between presence of lymphedema and CTS (P = 0.66) or between lymphedema severity and CTS severity (P = 0.79). There were no cases of infection or worsening lymphedema as a result of needle EMG. CONCLUSIONS: These findings do not support lymphedema as an etiologic factor in the pathogenesis of CTS.
