Seeking American Society of Clinical Oncology-Quality Oncology Practice Initiative (ASCO-QOPI) certification in a northern New England rural health system and cancer care network.

In 2006 following several years of preliminary study, the American Society of Clinical Oncology (ASCO) launched the Quality Oncology Practice Initiative (QOPI). This cancer-focused quality initiative evolved considerably over the next decade-and-a-half and is expanding globally. QOPI is undoubtedly the leading standard-bearer for quality cancer care and contemporary medical oncology practice. The program garners attention and respect among federal programs, private insurers, and medical oncology practices across the nation. The MaineHealth Cancer Care Network (MHCCN) has undergone expansive growth since 2017. The network provides cancer care to more than 70% of the cases in Maine in a largely rural health system in Northern New England. In fall 2020, the MHCCN QOPI project leadership, following collaborative discussions with the ASCO-QOPI team, elected to proceed with a health system-cancer network-wide QOPI certification. Key themes emerged over the course of our two-year journey including: (1) Developing a highly interprofessional team committed to the project; (2) Capitalizing on a single electronic medical record for data transmission to CancerLinQ; (3) Prior experience, especially policy development, in other cancer-focused accreditation programs across the network; and (4) Building consensus through quarterly stakeholder meetings and awarding Continuing Medical Education (CME) and American Board of Medical Specialists (ABMS) Maintenance of Certification (MOC) credits to oncologists. All participants demonstrated a genuine spirit to work together to achieve certification. We report our successful journey seeking ASCO-QOPI certification across our network, which to our knowledge is the first-of-its-kind endeavor.

Opioid initiation timing and palliative care referrals in advanced cancer: retrospective study.

OBJECTIVES: Early opioid initiation is recommended for advanced cancer pain, however the timing of opioid commencement in relation to diagnosis has not been described, and the role of palliative care prescribers is unclear. This study aims to determine the timing of opioid initiation by prescriber and cancer type in relation to key timepoints in the cancer illness course (diagnosis, palliative care referral and death). METHODS: This retrospective cohort study included patients at a quaternary cancer centre with incurable advanced cancer of five different subtype groups. Demographics, clinical characteristics, health service use and details of first slow and immediate release opioid prescription are reported. RESULTS: Among 200 patients, median time to first immediate release opioid prescription was 23 days (IQR 1-82) and to slow release opioid prescription was 47 days (IQR 14-155). Most patients (95%, (n=190) were referred to palliative care (median time to referral 54 days (IQR 18-190)). Non-palliative care prescribers initiated slow release opioids for half the cohort (49%, n=97) prior to referral. Patients with pancreatic cancer had the shortest time to slow/immediate release opioid prescription (median 10 days (IQR 0-39) and 26 days (IQR 1-43) respectively) and shortest survival (median 136 days (IQR 82-214)). CONCLUSIONS: Median time to opioid commencement was approximately 3 weeks after diagnosis. Despite early palliative care involvement, opioid initiation by non-palliative care clinicians was common and remains important. Timely palliative care referral for those with pancreatic cancer may include consideration of earlier complex pain presentations and shorter prognosis.

Prevalence, Severity, and Predictors of Insomnia in Advanced Colorectal Cancer.

CONTEXT: Insomnia is an under-recognized and undertreated symptom in palliative care and advanced cancer cohorts. Insomnia in an advanced colorectal cancer cohort is yet to be investigated despite colorectal cancer being the third commonest cancer worldwide and one with a high symptom burden. OBJECTIVES: To examine the prevalence of insomnia and its associations in a large advanced colorectal cancer cohort. METHODS: A consecutive cohort study of 18,302 patients with colorectal cancer seen by palliative care services across various settings (inpatient, outpatient, and ambulatory) was conducted from an Australia-wide database (2013-2019). The Symptom Assessment Score (SAS) was used to assess the severity of insomnia. Clinically significant insomnia was defined as SAS score ≥3/10, and used to compare associations with other symptoms and functional scores from validated questionnaires. RESULTS: The prevalence of any insomnia was 50.5%, and clinically significant insomnia 35.6%, particularly affecting people who were younger (<45-years-old), more mobile (AKPS score ≥70), or physically capable (RUG-ADL score ≤5). Outpatients and patients living at home had higher prevalence of insomnia. Nausea, anorexia and psychological distress were the commonest concurrent symptoms in patients with clinically significant insomnia. CONCLUSIONS: To our knowledge, this study was the first to investigate the prevalence and associations of insomnia in an advanced colorectal cancer cohort. Our findings demonstrate several groups at greater risk of suffering from insomnia (younger, greater physical capacity, living at home, and those with greater psychological distress). This may guide earlier recognition and management of insomnia to improve overall quality of life in this population.

Serotonin syndrome following methylene blue administration during cardiothoracic surgery.

INTRODUCTION: Despite its favorable safety profile, there have been reports of methylene blue-induced encephalopathy and serotonin syndrome in patients undergoing parathyroidectomy. We report a case of serotonin syndrome following methylene blue administration in a cardiothoracic surgery patient. CASE REPORT: A 59-year-old woman taking preoperative venlafaxine and trazodone was given a single dose of 2 mg/kg methylene blue (167 mg) during a planned coronary artery bypass and mitral valve repair. Postoperatively, she was febrile to 38.7°C and developed full-body tremors, rhythmic twitching of the perioral muscles, slow conjugate roving eye movements, and spontaneous movements of the upper extremities. Electroencephalography revealed generalized diffuse slowing consistent with toxic encephalopathy, and a computed tomography scan showed no acute process. The patient's symptoms were most consistent with a methylene blue-induced serotonin syndrome. Her motor symptoms resolved within 48 hours and she was eventually discharged home. DISCUSSION: Only 2 cases of methylene blue-induced serotonin syndrome during cardiothoracic surgery have been described in the literature, with this report representing the third case. Methylene blue and its metabolite, azure B, are potent, reversible inhibitors of monoamine oxidase A which is responsible for serotonin metabolism. Concomitant administration of methylene blue with serotonin-modulating agents may precipitate serotonin syndrome.

Docetaxel-associated palmar-plantar erythrodysesthesia: a case report and review of the literature.

Docetaxel-associated palmar-plantar erythrodysesthesia is rarely reported in literature, particularly when used in the treatment of sarcomas. Here, we report a case of docetaxel-related palmar-plantar erythrodysesthesia in a 28-year-old male with recurrent Ewing sarcoma. Although palmar-plantar erythrodysesthesia has been seen in the literature for 30 years, there has still been little progress in understanding and appropriately addressing this adverse effect. This case report and literature review illustrates an infrequently documented adverse skin reaction and discusses the etiology, presentation, and available treatment options for palmar-plantar erythrodysesthesia.

Epithelial healing and visual outcomes of patients using omega-3 oral nutritional supplements before and after photorefractive keratectomy: a pilot study.

PURPOSE: To investigate the effect of omega-3 oral nutritional supplementation on corneal reepithelialization, visual acuity, and tear stability after photorefractive keratectomy (PRK). METHODS: This is a prospective, randomized, single-blinded controlled therapeutic trial using omega-3 oral nutritional supplements (TheraTears Nutrition for Dry Eyes; Advanced Vision Research-Akorn, Ann Arbor, MI) conducted at our center. Eighteen healthy patients with refractive error between -1 and -8 diopters were recruited and had bilateral PRK. The treatment group (n = 9 subjects) received omega-3 2 weeks before surgery through 1 month after PRK. The control group (n = 9 subjects) was not given omega-3. Epithelial defects were photographed on postoperative days 0 to 5. Reepithelialization (area in square millimeters) was assessed by fluorescein staining until healing. Tear breakup time (TBUT) and uncorrected distance visual acuity were measured at 1 week, and 1 and 3 months postoperatively. RESULTS: Epithelial defect in the treatment group eyes healed faster compared with that of the controls (P = 0.04). The treatment group eyes healed at an average rate of 1.19% [SD = 0.002; 95% confidence interval (CI), 1.04%-1.34%] per hour, versus 0.83% (SD = 0.0008; 95% CI, 0.77%-0.89%) for controls (Mann-Whitney rank-sum test, P < 0.001). The treatment group eyes maintained a significantly longer TBUT from week 1 through 3 months (mean = 9.52 seconds, SD = 0.81; 95% CI, 8.93-10.10), compared with the controls (mean = 5.52 seconds, SD = 0.81; 95% CI, 4.93-6.10; P < 0.001), and all reached 20/20 vision versus only 4 in the control group 1 month after surgery (P = 0.03). CONCLUSIONS: Omega-3 oral nutritional supplements decreased the average time for epithelial healing, and improved TBUT and visual acuity recovery in PRK. These findings suggested that omega-3 oral nutritional supplementation may be a beneficial adjunct therapy for PRK patients.

Liposome-encapsulated curcumin suppresses growth of head and neck squamous cell carcinoma in vitro and in xenografts through the inhibition of nuclear factor kappaB by an AKT-independent pathway.

PURPOSE: The purpose of this study was to determine whether a liposomal formulation of curcumin would suppress the growth of head and neck squamous cell carcinoma (HNSCC) cell lines CAL27 and UM-SCC1 in vitro and in vivo. EXPERIMENTAL DESIGN: HNSCC cell lines were treated with liposomal curcumin at different doses and assayed for in vitro growth suppression using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. A reporter gene assay was done on cell lines to study the effect of liposomal curcumin on nuclear factor kappaB (NFkappaB) activation. Western blot analysis was done to determine the effect of curcumin on the expression of NFkappaB, phospho-IkappaBalpha, phospho-AKT (pAKT), phospho-S6 kinase, cyclin D1, cyclooxygenase-2, matrix metalloproteinase-9, Bcl-2, Bcl-xL, Mcl-1L, and Mcl-1S. Xenograft mouse tumors were grown and treated with intravenous liposomal curcumin. After 5 weeks, tumors were harvested and weighed. Immunohistochemistry and Western blot analyses were used to study the effect of liposomal curcumin on the expression of NFkappaB and pAKT. RESULTS: The addition of liposomal curcumin resulted in a dose-dependent growth suppression of both cell lines. Liposomal curcumin treatment suppressed the activation of NFkappaB without affecting the expression of pAKT or its downstream target phospho-S6 kinase. Expression of cyclin D1, cyclooxygenase-2, matrix metalloproteinase-9, Bcl-2, Bcl-xL, Mcl-1L, and Mcl-1S were reduced, indicating the effect of curcumin on the NFkappaB pathway. Nude mice xenograft tumors were suppressed after 3.5 weeks of treatment with i.v. liposomal curcumin, and there was no demonstrable toxicity of liposomal curcumin upon autopsy. Immunohistochemistry and Western blot analysis on xenograft tumors showed the inhibition of NFkappaB without affecting the expression of pAKT. CONCLUSIONS: Liposomal curcumin suppresses HNSCC growth in vitro and in vivo. The results suggest that liposomal curcumin is a viable nontoxic therapeutic agent for HNSCC that may work via an AKT-independent pathway.

Genetic abnormalities associated with nodal metastasis in head and neck cancer.

BACKGROUND: Lymphatic metastasis represents the single most important clinical prognostic factor in head and neck squamous cell carcinoma (HNSCC), but underlying genetic mechanisms remain ill defined. Genetic differences between primary carcinomas and their corresponding metastases might form a key to understanding the metastatic phenotype. In this study we aimed to characterize such differences using a genome-wide screening measure. METHODS: Four human cell lines (MDA-686tu, MDA-686Ln, MDA-1386tu, MDA-1386Ln) derived from primary tumor and synchronous lymph node metastasis of two cases of metastatic HNSCC were subjected to comparative genomic hybridization (CGH) by differentially labeling DNA from tumor tissue and normal tissue with fluorescent agents. The labeled DNAs were simultaneously hybridized onto normal metaphase chromosomes. In addition, modified CGH was performed by directly hybridizing labeled primary tumor DNA against differentially labeled metastatic tumor DNA, allowing the direct detection of copy number differences in individual pairs. Image analysis for fluorescence intensity along the entire length of each metaphase chromosome allowed generation of a color ratio, which was used to detect copy number changes. RESULTS: In both cases, significant overlap was found between chromosomal aberrations present in the primary tumor and the corresponding nodal metastasis. However, several abnormalities differentiated primary tumors from their metastases. Modified CGH identified several genetic aberrations that were not detectable with the conventional CGH analysis. Gains at chromosomes 10p11-12 and 11p and deletions at chromosomes 4q22-31, 9p13-24, and 14q differentiated nodal metastases from the corresponding primary tumors in both cases. CONCLUSIONS: The combination of conventional and modified CGH analyses facilitates the identification of DNA copy number changes that might be involved in the development of a metastatic phenotype. Future research should aim at the identification of the genes involved at the identified sites of chromosomal aberration.
