Objective: Rural–urban disparities in cancer care are well documented. However, research on rural–urban disparities regarding patient‐reported outcomes (PROs) is still developing. This study analyzed rural–urban disparities in patients with cancer with respect to anxiety, depression, fatigue, pain interference, and physical function.
Methods: This study was conducted at the University of Utah Huntsman Cancer Institute. We integrated data from electronic health records, Cancer Registry, and PRO questionnaires. We assessed the association between rurality status (rural vs. urban) in patients with cancer and PRO scores using multiple linear regression models and t‐tests.
Results: The cohort included 7271 patients. The mean age was 59.1 years at cancer diagnosis and 48.2% (n = 3505) were female. Across all cancer types, significant differences (Rural vs. Urban) were found for fatigue (53.6 vs. 54.1; p < 0.05) and physical function (45.5 vs. 45.1; p < 0.05). With respect to specific cancer types, there were differences in patients with oral cavity and pharynx cancer for depression (47.9 vs. 50.6; p < 0.01), fatigue (51.6 vs. 54.8; p < 0.05), pain interference (52.8 vs. 55.4; p < 0.05), and physical function (48.0 vs. 44.6; p < 0.01), colorectal cancer for fatigue (56.8 vs. 54.7; p < 0.05), pain interference (56.0 vs. 53.7; p < 0.05), and physical function (42.2 vs. 44.4; p < 0.05), uterus cancer for depression (47.5 vs. 50.5; p < 0.05) and fatigue (51.6 vs. 54.7; p < 0.05), and lung cancer for physical function (37.6 vs. 39.3; p < 0.05).
Conclusions: Across all cancer types, as well as specific cancers, this study found mostly limited rural–urban differences regarding PROs. Except for colorectal and lung/bronchus cancer, patients living in rural areas reported similar or better PRO scores for all cancer types. Results support the hypothesis that improving access can help to level rural–urban disparities regarding cancer care outcomes, because all patients were treated in the same comprehensive cancer center, had similar access to care, and had similar PRO scores.
Thecaloscopy Reduces the Risk of Recurrent Perineural (Tarlov) Cysts after Microsurgical Resection
(2024)
Sacral Tarlov cysts (TCs), often asymptomatic, can cause significant pain and severe neurological dysfunction. Conventional treatments are generally associated with high recurrence and complication rates. Specifically, the substantial recurrence rates, which can reach as high as 50%, significantly impact long-term outcomes. Recent evidence increasingly supports the hypothesis that the formation of Tarlov cysts (TCs) may be associated with inflammatory processes within the nerve root sheath, further exacerbated by elevated cerebrospinal fluid (CSF) pressure. This retrospective study explores thecaloscopy, combined with surgical techniques, as a more effective alternative. We observed a total of 78 patients, 48 of whom underwent endoscopic fenestration of the arachnoid sheath in addition to microsurgical resection of the TC. We found that the fenestration of the arachnoid sheath at the level of lumbosacral spinal nerve root entry led to a significantly decreased risk of developing recurrent TCs (5/48 vs. 9/30). Only one of the patients suffered from a persistent new bladder dysfunction after microsurgical resection. This presented technique provides a promising treatment path for the future management of TCs, offering a safe and more effective treatment option compared to previous methods. Additionally, the advantages of the thecaloscopy provide pathophysiological implications regarding the development of perineural cysts.
This case report presents the therapeutic effect of restorative neurostimulation (ReActiv8®) on chronic low back pain (CLBP) in a 44-year-old male, where the primary etiology was not lumbar disc herniation (LDH). Despite presenting with LDH at L4-L5, clinical valuations suggested lumbar microinstability and multifidus muscle dysfunction as the main contributors to his pain, without radicular symptoms. The patient had a 12-year history of CLBP, resistant to conventional treatments like physiotherapy, medications, and epidural injections. Opting for a minimally invasive approach, he underwent implantation of ReActiv8®, focusing on rehabilitating the impaired multifidus muscle. Over a 12-month therapy period, significant improvements were noted in pain levels, functionality, and quality of life, leading to a full return to work. Interestingly, follow-up imaging showed not only a substantial reduction in pain but also an unexpected resolution of the LDH at L4-L5, enhanced lumbar lordosis, and improved disc hydration, despite minor progressing Modic changes. This case underlines the potential of restorative neuro-stimulation in CLBP management, especially when the pain origin is non-discogenic. It emphasizes the importance of accurate pain source identification in CLBP treatment and suggests further research into the efficacy and applicability of neurostimulation in similar clinical scenarios.
