RESUMO
OBJECTIVE: To identify patient factors associated with acute care transfer (ACT) among cancer survivors admitted for inpatient medical rehabilitation. DESIGN: An exploratory, observational design was used to analyze retrospective data from electronic medical records. SETTING: Data were obtained from 3 separate inpatient rehabilitation hospitals within a private rehabilitation hospital system in the Northeast. PARTICIPANTS: Medical records were reviewed and analyzed for a total of 416 patients with a confirmed oncologic diagnosis treated in 1 of the inpatient rehabilitation hospitals between January and December 2020. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The primary outcome measure was the incidence of an ACT. Covariates included the adapted Karnofsky Performance Scale (KPS) for inpatient rehabilitation, demographic information, admission date, re-admission status, discharge destination, and cancer-related variables, such as primary cancer diagnosis and presence/location of metastases. RESULTS: One in 5 patients (21.2%) were transferred to acute care. Patients with hematologic cancer had a higher risk of ACT compared with those with central nervous system (CNS) cancer. Lower functional status, measured by the adapted KPS, was associated with a higher likelihood of ACT. Patients with an admission KPS score indicating the need for maximum assistance had the highest transfer rate (59.1%). CONCLUSIONS: These findings highlight the medical complexity of this population and increased risk of an interrupted rehabilitation stay. Considering patients' performance status, cancer type, and extent of disease may be important when assessing the appropriateness of IRF admission relative to patient quality of life. Earlier and improved understanding of the patient's prognosis will allow the cancer rehabilitation program to meet the patient's unique needs and facilitate an appropriate discharge to the community in an optimal window of time.

Answer questions and earn CME/CNE The American Cancer Society Head and Neck Cancer Survivorship Care Guideline was developed to assist primary care clinicians and other health practitioners with the care of head and neck cancer survivors, including monitoring for recurrence, screening for second primary cancers, assessment and management of long-term and late effects, health promotion, and care coordination. A systematic review of the literature was conducted using PubMed through April 2015, and a multidisciplinary expert workgroup with expertise in primary care, dentistry, surgical oncology, medical oncology, radiation oncology, clinical psychology, speech-language pathology, physical medicine and rehabilitation, the patient perspective, and nursing was assembled. While the guideline is based on a systematic review of the current literature, most evidence is not sufficient to warrant a strong recommendation. Therefore, recommendations should be viewed as consensus-based management strategies for assisting patients with physical and psychosocial effects of head and neck cancer and its treatment.

PURPOSE: Head and neck cancer (HNC) will be diagnosed in approximately 54,000 Americans in 2022 with more than 11,000 dying as a result. The treatment of HNC often involves aggressive multimodal therapy including surgery, radiotherapy, and systemic therapy. HNC and its treatments are associated with multiple painful and function-limiting neuromusculoskeletal and visceral long-term and late effects. Among these is head and neck lymphedema (HNL), the abnormal accumulation of protein rich fluid, in as many as 90% of survivors. Though HNL is common and potentially contributory to other function-limiting issues in this population, it is notoriously understudied, underrecognized, underdiagnosed, and undertreated. This study seeks to determine the incidence of HNC-related lymphedema diagnosis and treatment in a large US healthcare claims repository database. METHODS: A retrospective observational cohort design and data from an integrated US healthcare claims repository-the IBM MarketScan Commercial Claims and Encounters (CCAE) and Medicare Supplemental and Coordination of Benefits (MDCR) Databases spanning the period April 1, 2012 through March 31, 2020. RESULTS: Of the 16,654 HNC patients eligible for evaluation, 1,082 (6.5%) with a diagnosis of lymphedema were identified based on eligibility criteria. Of the 521 HNC patients evaluated for lymphedema treatment, 417 (80.0%) patients received 1.5 courses of MLD, 71 (13.6%) patients were prescribed compression garments, and 45 (8.6%) patients received an advanced pneumatic compression device. CONCLUSION: HNL in this population of HNC survivors was underdiagnosed and treated compared with contemporary assessments HNL incidence.

BACKGROUND: Persistent post-mastectomy pain (PPMP) is common after surgery. Although multiple modalities have been used to treat this type of pain, including medications, physical therapy, exercise interventions, cognitive-behavioral psychology, psychosocial interventions, and interventional approaches, managing PPMP may be still a challenge for breast cancer survivors. Currently, serratus plane block (SPB) as a novel regional anesthetic technique shows promising results for controlling chronic pain. METHODS: We report four cases of patients with PPMP that were treated using superficial serratus plane block (SSPB) at our clinic. A retrospective review of effect of pain relief was collected through postprocedure interviews. RESULTS: We found that two of our patients were successfully treated with SSPB for pain after treatment for breast cancer. The third patient had an intercostobrachial nerve block that produced incomplete pain relief but had adequate pain relief with a SSPB. However, the fourth patient reported no pain relief after SSPB. CONCLUSION: These cases illustrate that the patients with PPMP could benefit from SSPB. Particularly, we find patients with a subjective sense of "tightness" relating to reconstructive surgeries may be a good candidate for SSPB. Further studies are warranted to evaluate this block for PPMP, as it is low risk and relatively simple to perform.

OBJECTIVE The object of this study was to determine the percentage of high-dose (1800-2600 cGy) single-fraction stereotactic radiosurgery (SF-SRS) treatments to the spine that result in peripheral nervous system (PNS) injury. METHODS All patients treated with SF-SRS for primary or metastatic spine tumors between January 2004 and May 2013 and referred to the Rehabilitation Medicine Service for evaluation and treatment of neuromuscular, musculoskeletal, or functional impairments or pain were retrospectively identified. RESULTS Five hundred fifty-seven SF-SRS treatments in 447 patients resulted in 14 PNS injuries in 13 patients. All injures resulted from SF-SRS delivered to the cervical or lumbosacral spine at 2400 cGy. The overall percentage of SF-SRS treatments resulting in PNS injury was 2.5%, increasing to 4.5% when the thoracic spine was excluded from analysis. The median time to symptom onset following SF-SRS was 10 months (range 4-32 months). The plexus (cervical, brachial, and/or lumbosacral) was affected clinically and/or electrophysiologically in 12 (86%) of 14 cases, the nerve root in 2 (14%) of 14, and both in 6 (43%) of 14 cases. All patients experienced pain and most (93%) developed weakness. Peripheral nervous system injuries were CTCAE Grade 1 in 14% of cases, 2 in 64%, and 3 in 21%. No dose relationship between SF-SRS dose and PNS injury was detected. CONCLUSIONS Single-fraction SRS to the spine can result in PNS injury with major implications for function and quality of life.

The health care delivery system in the United States is challenged to meet the needs of a growing population of cancer survivors. A pressing need is to optimize overall function and reduce disability in these individuals. Functional impairments and disability affect most patients during and after disease treatment. Rehabilitation health care providers can diagnose and treat patients' physical, psychological, and cognitive impairments in an effort to maintain or restore function, reduce symptom burden, maximize independence and improve quality of life in this medically complex population. However, few care delivery models integrate comprehensive cancer rehabilitation services into the oncology care continuum. The Rehabilitation Medicine Department of the Clinical Center at the National Institutes of Health with support from the National Cancer Institute and the National Center for Medical Rehabilitation Research convened a subject matter expert group to review current literature and practice patterns, identify opportunities and gaps regarding cancer rehabilitation and its support of oncology care, and make recommendations for future efforts that promote quality cancer rehabilitation care. The recommendations suggest stronger efforts toward integrating cancer rehabilitation care models into oncology care from the point of diagnosis, incorporating evidence-based rehabilitation clinical assessment tools, and including rehabilitation professionals in shared decision-making in order to provide comprehensive cancer care and maximize the functional capabilities of cancer survivors. These recommendations aim to enable future collaborations among a variety of stakeholders to improve the delivery of high-quality cancer 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.

Cancer rehabilitation is a rapidly emerging and evolving medical field in both Europe and the United States, in large part because of increases in the number of cancer survivors. Although few argue with the need to restore function and quality of life to patients affected by cancer and its treatments, differences exist between European countries with regard to the funding, accessibility, and even the definition of cancer rehabilitation services. In the United States, there is tremendous variability in the provision of rehabilitation services resulting from a variety of factors, including a lack of highly trained cancer rehabilitation physicians and therapists as well as a lack of comprehensive cancer rehabilitation programs, even at the majority of top cancer centers. Although studies evaluating the effectiveness of rehabilitation programs in the cancer setting, particularly exercise, have influenced clinical decision-making in both Europe and the United States for some time, this emerging evidence base also is now starting to influence guideline and policy making. Coordinated research efforts are essential to establish a robust framework to support future investigation and establish shared initiatives. Determining the best way forward for cancer survivors will require investment in large-scale prospective cohort studies that sufficiently describe their rehabilitation needs through the continuum of the survivorship experience.

BACKGROUND: Spinal metastases frequently arise in patients with cancer. Modern oncology provides numerous treatment options that include effective systemic, radiation, and surgical options. We delineate and provide the evidence for the neurologic, oncologic, mechanical, and systemic (NOMS) decision framework, which is used at Memorial Sloan-Kettering Cancer Center to determine the optimal therapy for patients with spine metastases. METHODS: We provide a literature review of the integral publications that serve as the basis for the NOMS framework and report the results of systematic implementation of the NOMS-guided treatment. RESULTS: The NOMS decision framework consists of the neurologic, oncologic, mechanical, and systemic considerations and incorporates the use of conventional external beam radiation, spinal stereotactic radiosurgery, and minimally invasive and open surgical interventions. Review of radiation oncology and surgical literature that examine the outcomes of treatment of spinal metastatic tumors provides support for the NOMS decision framework. Application of the NOMS paradigm integrates multimodality therapy to optimize local tumor control, pain relief, and restoration or preservation of neurologic function and minimizes morbidity in this often systemically ill patient population. CONCLUSION: NOMS paradigm provides a decision framework that incorporates sentinel decision points in the treatment of spinal metastases. Consideration of the tumor sensitivity to radiation in conjunction with the extent of epidural extension allows determination of the optimal radiation treatment and the need for surgical decompression. Mechanical stability of the spine and the systemic disease considerations further help determine the need and the feasibility of surgical intervention.

OBJECTIVE: To evaluate the delayed effects of irreversible electroporation (IRE) ablation on nerves. METHODS: The study was approved by the institutional animal care and use committee. CT-guided IRE-ablation (electric field per distance, 1,500 V/cm; pulse length, 70 µs; number of pulses, 90) of 6 sciatic nerves was performed in 6 pigs that were euthanized 2 months after ablation. The sciatic nerves were harvested immediately after euthanasia for histopathological evaluation. Sections from selected specimens were stained with haematoxylin and eosin (H&E), Masson's trichrome (MT) method for collagen, and immunohistochemistry was performed for S100 and neurofilaments (markers for Schwann cells and axons, respectively). RESULTS: All nerves showed a preserved endoneural architecture and presence of numerous small calibre axons associated with Schwann cell hyperplasia, consistent with axonal regeneration. A fibrous scar was observed in the adjacent muscle tissue, confirming ablation at the site examined. CONCLUSION: After IRE-ablation of nerves, the preservation of the architecture of the endoneurium and the proliferation of Schwann cells may enable axonal regeneration as demonstrated after 2 months in this study.

Purpose of Review: Despite more than 6 decades of growth and transformation, the field of cancer rehabilitation has considerable room to evolve if it is to live up to its full potential. This article will discuss the importance of this evolution in the context of radiation late effects and serve as a call for the clinical and operational expansion of the field so that it can become a key component of comprehensive cancer care. Recent Findings: The clinical and operational challenges inherent in cancer survivors with radiation late effects necessitate different thinking with respect to how rehabilitation professionals evaluate and manage patients as well as how our institutions equip these professionals to practice at the highest possible level. Summary: To achieve its promise, the field of cancer rehabilitation must evolve to embrace fully the scope, scale, and complexity of issues faced by cancer survivors with radiation late effects. Better engagement and coordination of the care team are needed to deliver this care and ensure our programs are robust, sustainable, and flexible.
RESUMO
BACKGROUND: Better tools are needed to predict functional decline and oncologic prognosis in inpatient cancer rehabilitation. The Karnofky Performance Status (KPS) is a widely used scale of functional performance in oncology, although the scale differs from current rehabilitation terminology. Use of the KPS in inpatient rehabilitation may support a shared method of communication between cancer rehabilitation providers and the primary oncology teams. OBJECTIVE: To establish interrater reliability for translation of the KPS for use in inpatient cancer rehabilitation. DESIGN: Retrospective interrater reliability review. SETTING: A large inpatient rehabilitation hospital system. PARTICIPANTS: Fifty randomized charts were chosen for review from a larger database of all patients admitted to an inpatient cancer rehabilitation program in 2020. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: The KPS scale was translated into common inpatient rehabilitation grading consistent with the Continuity and Assessment Record and Evaluation (CARE) Item Set to support its use in this specialty area. Additionally, a list of best practice guidelines and scoring instructions were created to assist raters in determining appropriate levels within the scale. Members of the inpatient cancer rehabilitation team scored all patients within the larger database (n = 424) throughout 2020. A blinded rater completed retrospective chart reviews to score the 50-chart sample. A two-way random effects model was used to calculate an intraclass correlation coefficient (ICC) for the KPS scores at each of three time points (premorbid, admission, and discharge). RESULTS: The KPS interpretation for rehabilitation proved to be statistically reliable for the 50-chart sample. The premorbid KPS interrater reliability was acceptable (ICC = 0.67; 95% confidence interval [CI]: 0.40-0.82), admission KPS reliability was good (ICC = 0.88, 95% CI: 0.78-0.93), and discharge reliability was excellent (ICC = 0.96; 95% CI: 0.91-0.98). CONCLUSION: The KPS translation at three time points (premorbid, admission, and discharge) during the inpatient rehabilitation continuum has acceptable interrater reliability.

Chemotherapy-induced peripheral neuropathy (CIPN) results from damage to or dysfunction of the peripheral nerves. The development of CIPN is anticipated for the majority of breast cancer patients who receive neurotoxic chemotherapy, depending on the agent used, dose, and schedule. Sensory symptoms often predominate and include numbness, tingling, and distal extremity pain. Weakness, gait impairment, loss of functional abilities, and other deficits may develop with more severe CIPN. This article outlines a prospective surveillance model for physical rehabilitation of women with breast cancer who develop CIPN. Rehabilitative efforts for CIPN start at the time of breast cancer diagnosis and treatment planning. The prechemotherapy evaluation identifies patients with preexisting peripheral nervous system disorders that may place them at higher risk for the development of CIPN. This clinical evaluation should include a history focusing on symptoms and functional activities as well as a physical examination that objectively assesses the patient's strength, sensation, reflexes, and gait. Ongoing surveillance following the initiation of a neurotoxic agent is important to monitor for the development and progression of symptoms associated with CIPN, and to ensure its resolution over the long term. CIPN is managed best by a multidisciplinary team approach. Early identification of symptoms will ensure appropriate referral and timely symptom management. The prospective surveillance model promotes a patient-centered approach to care, from pretreatment through survivorship and palliative care. In this way, the model offers promise in addressing and minimizing both the acute and long-term morbidity associated with CIPN.

BACKGROUND: Hodgkin lymphoma (HL) is highly curable, but survivors often develop function-limiting impairments. Screening guidelines for neuromuscular and musculoskeletal late effects are not as well recognized across medical disciplines. Early identification and management of functional late effects are instrumental in improving the longitudinal care of HL survivors. OBJECTIVE: To define the prevalence of neuromuscular, musculoskeletal, visceral, oncologic, and other late effects affecting function and quality of life (QOL) in HL survivors. DESIGN: A retrospective cohort analysis. SETTING: Outpatient cancer rehabilitation clinic. PARTICIPANTS: One hundred HL survivors. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Prevalence of neuromuscular, musculoskeletal, visceral, oncologic, and other late effects contributing to functional impairment and disability in HL survivors. RESULTS: Among the 100 HL survivors, 43% received chemotherapy, 94% radiation therapy, and 38% a combination of chemo-radiation for their initial cancer treatment. Nearly all HL survivors were diagnosed with myelopathy (83%), radiculoplexopathy (93%), mononeuropathy (95%), and localized myopathy (93%). Musculoskeletal sequelae included dropped head syndrome (83%), cervicalgia (79%), shoulder girdle dysfunction (73%), and dysphagia (42%). Visceral disorders included cardiovascular (70%), pulmonary (44%), endocrine (63%), gastrointestinal (29%), and genitourinary (11%) dysfunction. Lymphedema affected 21% of survivors and 30% had a history of a secondary malignancy. Pain (71%), fatigue (45%), and dyspnea (43%) were major function-limiting impairments. Nearly all (95%) of survivors were referred to at least one therapy discipline including physical therapy, occupational therapy, speech and language pathology, and/or lymphedema therapy. CONCLUSION: Neuromuscular, musculoskeletal, visceral, oncologic, and other late effects are extremely common in HL survivors seeking physiatric evaluation. Multiple function-limiting disorders can coexist in HL survivors with the potential to severely compromise function and QOL. Safe and effective rehabilitation may depend on the physiatrist's ability to identify, evaluate, and manage the multitude of complex and often interrelated functional late effects seen in HL survivors.

PURPOSE: To evaluate whether irreversible electroporation (IRE) has the potential to damage nerves in a porcine model and to compare histopathologic findings after IRE with histopathologic findings after radiofrequency ablation (RFA). MATERIALS AND METHODS: This study was approved by the institutional animal care and use committee. Computed tomography (CT)-guided IRE of 11 porcine sciatic nerves was performed in nine pigs, and histopathologic analysis was performed on the day of ablation or 3, 6, or 14 days after ablation. In addition, acute RFA of six porcine sciatic nerves was performed in six pigs that were harvested on the day of ablation. All nerves and associated muscles and tissues were assessed for histopathologic findings consistent with athermal or thermal injury, respectively, such as axonal swelling, axonal fragmentation and loss, Wallerian degeneration, inflammatory infiltrates, Schwann cell proliferation, and coagulative necrosis. The percentage of fascicles affected was recorded. RESULTS: All nerves had an axonal injury. The percentage of affected nerve fascicles after IRE was 50%-100%. Axonal swelling and perineural inflammatory infiltrates were detectable at every time point after ablation. Axonal fragmentation and loss, macrophage infiltration, and Schwann cell proliferation were found 6 and 14 days after ablation. Distal Wallerian axonal degeneration was observed 14 days after ablation. The endoneurium and perineurium architecture remained intact in all cases. RFA specimens at the day of ablation revealed acute coagulative necrosis associated with intense basophilic staining of extracellular matrix, including collagen of the perineurium and epineurium consistent with thermal injury. CONCLUSION: IRE has the potential to damage nerves and may result in axonal swelling, fragmentation, and distal Wallerian degeneration. However, preservation of endoneurium architecture and proliferation of Schwann cells may suggest the potential for axonal regeneration. In contrast, RFA leads to thermal nerve damage, causing protein denaturation, and suggests a much lower potential for regeneration.

OBJECTIVE: To examine the effectiveness of a dynamic jaw opening device as part of a multimodal treatment strategy for trismus in patients with head and neck cancer. DESIGN: Retrospective cohort study. SETTING: Tertiary care cancer center. PARTICIPANTS: Patients with head and neck cancer and trismus (N=20). INTERVENTION: All patients underwent assessment by a board-certified physiatrist and were referred to physical therapy for delivery of the DTS and instructed to progress use of the DTS to 30 minutes 3 times a day. Additional modalities for the treatment of trismus including pain medications and botulinum toxin injections were prescribed as clinically indicated. MAIN OUTCOME MEASURES: Change in maximal interincisal distance (MID) as documented in the medical record. RESULTS: The use of the DTS as part of multimodal therapy including physical therapy, pain medications, and botulinum toxin injections as deemed clinically appropriate resulted in an overall improvement of the MID from 16.5mm to 23.5mm (P<.001). Patients who could comply with the treatment recommendations for DTS treatment did better than those who could not, with an improvement of the MID from 16 mm to 27 mm (P<.001) versus 17 mm to 22 mm (P=.88). CONCLUSIONS: The DTS is a safe and effective component of a multimodal strategy for improving trismus associated with head and neck cancer and its treatment. Further investigation is needed to determine the relative efficacy of the treatment modalities available for trismus including physical therapy and other jaw stretching devices.

OBJECTIVES: To define radiation fibrosis and radiation fibrosis syndrome; review the basics of radiotherapy, the pathophysiology of radiation injury, and the principles of clinical evaluation and management of the common late effects resulting from radiation therapy for cancer treatment. DATA SOURCES: Peer-reviewed journal articles, book chapters, Internet. CONCLUSION: There is no cure for radiation fibrosis syndrome, but supportive treatment of its clinical sequelae can potentially result in improved function and quality of life. IMPLICATIONS FOR NURSING PRACTICE: The sequelae of radiation fibrosis syndrome can often be improved with early detection and supportive care by a multidisciplinary team including cancer rehabilitation physiatrists, oncologists, oncology nurses, nurse practitioners, physical therapists, occupational therapists, and speech and language pathologists.

Individuals with cancer commonly experience functional impairments. Symptoms may present immediately or years to decades following their treatment. These impairments may include fatigue, pain, neuropathy, lymphedema, or radiation fibrosis syndrome and have the potential to deleteriously impact their function and quality of life. Cancer rehabilitation is a comprehensive resource that facilitates maximizing and maintaining cancer survivors' physical, social, psychological, and vocational functioning. This article covers the common functional impairments experienced by cancer survivors and the treatment strategies used in cancer rehabilitation. Application of these services can enhance the ongoing care for cancer survivors.
