Abstract
PURPOSE OF REVIEW This review summarizes the latest advancements in survivorship care for patients with advanced melanoma who received systemic therapy and emphasizes the areas where more research is needed. RECENT FINDINGS Over the last decade there have been remarkable advances in the treatment of advanced and metastatic melanoma. Due to these novel treatments, including several immune checkpoint inhibitors and tyrosine kinase inhibitors, there are and will continue to be increasing numbers of long-term melanoma survivors who have been treated with systemic therapy. These patients will navigate new challenges are they are essentially among the first long term survivors after these novel therapies. Survivorship care focuses on improving the health-related quality of life of patients including the physical, emotional, social and functional effects of cancer that begin at diagnosis and continue through the end of life. Survivorship also includes screening for cancer recurrence and second cancers. As the number of melanoma survivors who received systemic therapy continues to grow, the survivorship care plan will become increasingly important for optimal care of patients even after their cancer treatments. Understanding the many domains of survivorship care for this group of patients is imperative for their care now and to identify unmet needs for future research.

Abstract
This report describes the use of subcutaneous lidocaine infusion to manage complex pain associated with checkpoint inhibitor inflammatory arthritis. In addition, the safe administration of lidocaine in the home setting is described. A 49-year-old man with metastatic melanoma to lung, right axilla and posterior chest wall on regular pembrolizumab developed checkpoint inhibitor inflammatory arthritis. Pain associated with this was unresponsive to simple analgesia, escalating opioids and adjuvant analgesics. Lidocaine infusion was used on separate occasions (inpatient unit and home setting) to gain rapid and sustained control of inflammatory pain. Inflammatory pain responded well to 2 mg/kg/h lidocaine infusion over 4 days with sustained response between infusions of up to 6 wk. Resulting in improved mobility, functional status, and overall quality of life. Lidocaine infusion should be considered as an option for analgesic management of checkpoint inhibitor inflammatory arthritis in patients for whom usual treatment is ineffective, and as an opioid-sparing intervention.

Abstract
OBJECTIVES The objective of this study was to determine baseline risk factors for requiring immunosuppression and having persistent arthritis in patients with immune checkpoint inhibitor-induced inflammatory arthritis (ICI-inflammatory arthritis). METHODS Participants were adults with rheumatologist diagnosed ICI-inflammatory arthritis. The primary outcome was requirement of conventional synthetic (cs) or biologic (b) DMARDs; other outcomes were persistence of inflammatory arthritis >6 months after ICI cessation and requirement of CSs. Logistic regression models evaluated associations between clinical features and primary and secondary outcomes, with adjustment for potential confounders, as appropriate. RESULTS One hundred and twenty-six patients with ICI-inflammatory arthritis were included; 53 patients (42%) required a csDMARD/bDMARD. In the univariate logistic regression analysis, higher clinical disease activity index (CDAI), tenosynovitis, longer symptom duration before first rheumatology visit and longer ICI duration were significantly associated with a higher likelihood of requiring DMARDs; in addition, there was a trend towards those treated with prior chemotherapy being less likely to need DMARDs. After adjustment, tenosynovitis, longer symptom duration and higher CDAI remained associated with requiring DMARDs, while those with prior chemotherapy were significantly less likely to require DMARDs. Combination anti-CTLA-4 (cytotoxic T-lymphocyte-associated protein-4)/PD-1 (Programmed cell death protein-1) therapy and CS use at baseline were associated with a higher risk of persistent inflammatory arthritis. CONCLUSION Higher levels of disease activity, tenosynovitis and longer symptom duration prior to rheumatology referral were associated with requiring DMARDs for ICI-inflammatory arthritis, while those treated previously with chemotherapy were less likely to require additional immunosuppression. The presence of risk factors for severe disease at baseline may indicate a role for higher initial CS dose, earlier rheumatology referral, and adoption of immunosuppression beyond CSs to improve outcomes.

Abstract
The introduction of immune checkpoint inhibitors (ICIs) has changed the landscape of the treatment of cancer. Several immune-related adverse events (irAEs) have now been described such as ICI-inflammatory arthritis (IA), sicca syndrome, polymyalgia rheumatica, myositis, and vasculitis as a consequence of immune activation. The onset of the ICI-IA can vary from after the first infusion of ICIs to a delayed presentation a year or more after ICI initiation. Ultimately, baseline patient and tumor characteristics, the types of immunotherapies used, pre-existing autoimmune diseases, and/or other irAEs, as well as patient preferences will all shape the discussions around ICI-IA management.

Abstract
Polymyalgia rheumatica (PMR) immune-related adverse events (ICI-PMRs) represent a novel, distinct entity, despite many clinical, laboratory, and imaging similarities to classical PMR. Important questions remain in differentiating ICI-PMR from classical PMR, as well as other immune-related adverse events and PMR mimics. Despite this, ICI-PMR currently takes treatment cues from classical PMR, albeit with considerations relevant to cancer immunotherapy. Comparisons between ICI-PMR and classical PMR may provide further bidirectional insights, especially given that important questions remain unanswered about both diseases. The cause of classical PMR remains poorly understood, and ICI-PMR may represent a model of induced PMR, with important therapeutic implications.

Abstract
Patients with cancer considering immune checkpoint inhibitor (ICI) therapy often look for health information and peer support through online communities. The authors used social media content analysis to obtain the perspectives of patients receiving ICI treatment about immune-related adverse events (irAEs), with particular focus on rheumatological symptoms. The most reported rheumatic symptom was joint pain. Other commonly reported symptoms included muscle pain, joint stiffness, arthritis, myositis, bone pain, back pain, and tendon/ligament pain. A few users reported development of rheumatic diseases. The authors' analyses allowed for cataloging and assessment of patient and caregiver experiences with ICI therapy and rheumatic irAEs.

Abstract
Immune checkpoint inhibitors have revolutionised the treatment of cancer. While very effective, they commonly cause a wide spectrum of immune-related adverse events. These immune-related adverse events can be fatal and often have significant effects on quality of life. They therefore require prompt recognition and management. We report the case of a woman presenting with widespread joint pain and stiffness 6 hours after her first pembrolizumab infusion. She had no joint swelling on physical examination but an ultrasound scan revealed widespread musculoskeletal inflammation, confirming the diagnosis of inflammatory arthritis. To the best of our knowledge, this is the fastest reported inflammatory arthritis onset following immune checkpoint inhibitor treatment. It highlights the importance of timely imaging in patients on immune checkpoint inhibitors who present with new non-specific musculoskeletal pain. Her symptoms improved dramatically with intramuscular triamcinolone injection.

Abstract
Objective Immunotherapeutic approaches to cancer, such as dendritic cell vaccine therapy, promise to improve survival rate but may present unique challenges to patients. However, there is no research on the lived experiences of cancer patients receiving dendritic cell vaccine therapy. The aim of this study was to explore the attitudes, expectations, and experiences of cancer patients receiving dendritic cell vaccine therapy in Japan. Methods This was an exploratory qualitative study. A descriptive phenomenological approach was used to investigate the experiences of eight advanced-stage cancer patients (median age: 59.5 years). Data were collected between July 2018 and March 2020 using in-depth semi-structured interviews. Data were analyzed according to Colaizzi's seven-step phenomenological strategy, and EQUATOR's Consolidated Criteria for Reporting Qualitative Research (COREQ) guidelines for qualitative studies were followed. Results Four themes emerged from the data analysis: strong concerns about chemotherapy, faith in dendritic cell vaccine therapy, motivation to succeed, and physical and mental changes. The first two themes related to pretreatment attitudes and expectations. The latter two themes expressed participants' experiences during and after therapy. Conclusions Dendritic cell vaccine therapy patients expressed fears about the effects of standard treatment, and hope and uncertainty regarding immunotherapy treatment decisions and efficacy. The findings suggest that such patients require nursing care that includes prevention and reduction of chemotherapy side effects, careful observation of patients' well-being, management of patients' expectations and uncertainty, formation of patient-health care practitioner partnerships, and team medicine.

Abstract
Patients with pre-existing autoimmune disorders and cancer considering immune checkpoint inhibitors (ICIs) need to receive balanced information about the benefits and risk of developing immune-related adverse events (irAEs) and flare-ups of their autoimmune disease. To assess the learning needs of patients with cancer and pre-existing autoimmune disease regarding ICI treatment, we interviewed 29 patients with autoimmune disease and cancer from a comprehensive cancer center, of whom 20 had received ICI and 9 were candidates to receive ICI at a US Cancer Center. In-depth semi-structured interviews were conducted from August 2021 and January 2022. Interviewee's opinions and preferences about content and information delivery methods were collected. We recorded and transcribed interviews and analyzed them using thematic analysis. Half of the participants were female, and their median (SD) age was 62.9 (±10.9) years. The identified health information needs included the following: (1) information on irAEs and autoimmune disease flare-ups; (2) benefits of ICI; (3) ICI mechanism in the context of autoimmune disease; (4) management of flare-ups; (5) reasons for stopping or modifying cancer or autoimmune disease treatment; (6) likelihood of autoimmune disease progression or organ damage; and (7) lifestyle changes that could help avoid irAEs. Patients who had received ICI and those who had not yet received treatment reported similar needs, although patients who had received ICI had more questions about cancer treatment modifications. Patients also expressed the need to better understand when to contact their provider and how to share information with multiple providers. Most patients wanted to receive information in visual formats for review at home and at their own pace. Patients expressed interest in having educational tools to facilitate shared decision-making with their physicians, and they identified several areas of health information concerning therapy with ICI. They also highlighted the importance of communication among their various providers.

Abstract
Immune-related adverse events (irAEs) are toxicities resulting from use of immune checkpoint inhibitors (ICIs). These side effects persist in some patients despite withholding therapy and using immunosuppressive and immune-modulating agents. Little is known about chronic irAEs and they are felt to be rare. We performed a systematic review to characterize non-endocrine chronic irAEs reported in the literature and describe their management. Ovid MEDLINE and Embase databases were searched for reports of adult patients with solid cancers treated with ICIs who experienced chronic (>12 weeks) non-endocrine irAEs. Patient, treatment and toxicity data were collected. Of 6843 articles identified, 229 studies including 323 patients met our inclusion criteria. The median age was 65 (IQR 56-72) and 58% were male. Most patients (75%) had metastatic disease and the primary cancer site was melanoma in 43% and non-small cell lung cancer in 31% of patients. The most common ICIs delivered were pembrolizumab (24%) and nivolumab (37%). The chronic irAEs experienced were rheumatological in 20% of patients, followed by neurological in 19%, gastrointestinal in 16% and dermatological in 14%. The irAE persisted for a median (range) of 180 (84-2370) days and 30% of patients had ongoing symptoms or treatment. More than half (52%) of patients had chronic irAEs that persisted for >6 months. The ICI was permanently discontinued in 60% of patients and 76% required oral and/or intravenous steroids. This is the first systematic review to assess and report on moderate/severe chronic non-endocrine irAEs after treatment with ICI in the literature. These toxicities persisted for months-years and the majority required discontinuation of therapy and initiation of immunosuppression. Further research is needed to better understand chronic irAEs, which hold potential substantial clinical significance considering the expanded use of ICIs and their integration into the (neo)adjuvant settings.

Abstract
Immune checkpoint inhibitors (ICIs) have improved cancer outcomes but can cause severe immune-related adverse events (irAEs) and flares of autoimmune conditions in cancer patients with pre-existing autoimmune disease. The objective of this study was to identify the information physicians perceived as most useful for these patients when discussing treatment initiation with ICIs. Twenty physicians at a cancer institution with experience in the treatment of irAEs were interviewed. Qualitative thematic analysis was performed to organize and interpret data. The physicians were 11 medical oncologists and 9 non-oncology specialists. The following themes were identified: (1) current methods used by physicians to provide information to patients and delivery options; (2) factors to make decisions about whether or not to start ICIs in patients who have cancer and pre-existing autoimmune conditions; (3) learning points for patients to understand; (4) preferences for the delivery of ICI information; and (5) barriers to the implementation of ICI information in clinics. Regarding points to discuss with patients, physicians agreed that the benefits of ICIs, the probability of irAEs, and risks of underlying autoimmune condition flares with the use of ICIs were most important. Non-oncologists were additionally concerned about how ICIs affect the autoimmune disease (e.g., impact on disease activity, need for changes in medications for the autoimmune disease, and monitoring of autoimmune conditions).

Abstract
PURPOSE This study aimed to translate and culturally adapt the immune checkpoint modulator (ICM) subscale of the Functional Assessment of Cancer Therapy-Immune Checkpoint Modulator (FACT-ICM) scale and to validate the FACT-ICM scale in Chinese cancer patients receiving immune checkpoint inhibitors (ICIs) treatment. METHODS In total, 354 cancer patients treated with ICIs were included in our cross-sectional study including 2 phases. Firstly, the ICM subscale was translated and culturally adapted by standardized procedures. Then the FACT-ICM scale was validated, which included item analysis, content validity, floor and ceiling effects, internal consistency reliability, test-retest reliability, construct validity, convergent/divergent validity, and known-group validity. RESULTS The content validity indexes at the item and scale level of the ICM subscale were greater than 0.8. No floor and ceiling effects were found. The Cronbach's α and McDonald's omega coefficients of the simplified Chinese version of the FACT-ICM scale were 0.935 and 0.936, and the intraclass correlation coefficient was 0.833 (95% confidence interval: 0.574-0.940). Confirmatory factor analysis confirmed the 5-subscale structure of the simplified Chinese version of the FACT-ICM scale (χ2/df = 2.144, RMSEA = 0.057, SRMR = 0.072, and CFI = 0.848). Convergent and divergent validity further supported the construct validity of the simplified Chinese version of the FACT-ICM scale. The known-group validity of the simplified Chinese version of the FACT-ICM scale was confirmed in patients with different physical statuses. CONCLUSIONS The simplified Chinese version of the FACT-ICM scale is a valid and reliable instrument and can be used in clinical practice and research on cancer patients receiving ICIs treatment.

Abstract
Immune checkpoint inhibitors (ICIs), used to treat many advanced cancers, activate the immune system to elicit an antitumor response. ICIs can also cause immune-related adverse events (irAEs) when nontumor tissues are affected by excess inflammation and autoimmunity. Rheumatic irAEs include inflammatory arthritis, myositis, sicca syndrome, polymyalgia rheumatica, and several other rare phenotypes. Treating rheumatic irAEs requires balancing the desire to decrease off-target inflammation while not negatively impacting the antitumor immune response. In this review, treatment recommendations for rheumatic irAEs have been discussed. Pathogenesis of rheumatic irAEs has been briefly reviewed. Knowledge about the effects of corticosteroids and steroid-sparing agents on tumor responses has been detailed to give context for treatment decisions. Recommendations ultimately depend not only on the clinical presentation and severity of the irAE but also on the goals of cancer treatment. Finally, how to safely use ICI therapy in patients with preexisting autoimmune diseases is considered.

Early Increase of Circulating Transitional B Cells and Autoantibodies to Joint-Related Proteins in Patients With Metastatic Melanoma Developing Checkpoint Inhibitor-Induced Inflammatory Arthritis. Arthritis Rheumatol 2022; 75:856-863. [PMID: 36409578 DOI: 10.1002/art.42406] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 09/20/2022] [Accepted: 11/08/2022] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To investigate potential associations between B cell-related immunologic changes and development of inflammatory arthritis (IA) after treatment with immune checkpoint inhibitors (ICIs). METHODS Patients who developed ICI-induced IA (ICI-IA) and patients who did not develop immune-related adverse events (non-IRAE) after receiving ICIs to treat metastatic melanoma were consecutively recruited. Blood samples were collected at the time of ICI-IA occurrence and at different time points during treatment. Peripheral blood B cell subsets during ICI treatment were analyzed by flow cytometry. Rheumatoid factor, anti-citrullinated protein antibodies, and antibodies against joint-related proteins were measured. RESULTS Proportions of CD19+ B cells were higher in patients with ICI-IA (n = 7) compared to patients with non-IRAE (n = 15) (median 11.7% [interquartile range (IQR) 9.7-16.2%] versus 8.1% [IQR 5.7-11.0%]; P = 0.03). The proportion and absolute numbers of transitional CD19+CD10+CD24high CD38high B cells were increased in patients with ICI-IA compared to non-IRAE patients (median 8.1% [IQR 4.9-12.1%] versus 3.6% [IQR 1.9-4.9%]; median 10.7 cells/μl [IQR 8.9-19.6] versus 4.4 cells/μl [IQR 2.3-6.6]; P < 0.01 for both). In addition, higher levels of transitional B cells were associated with development of ICI-IA (odds ratio 2.25 [95% confidence interval 1.03-4.9], P = 0.04). Transitional B cells increased before the onset of overt ICI-IA and decreased between the active and quiescent stages of ICI-IA (P = 0.02). Autoantibodies to type II collagen epitopes were detected in up to 43% of ICI-IA patients compared to none of the non-IRAE patients (P = 0.02). CONCLUSION Development of ICI-IA is accompanied by an increase in transitional B cells and by production of autoantibodies to joint-related proteins. Monitoring of B cell-driven abnormalities upon ICI treatment may help earlier recognition of ICI-IA.

Abstract
BACKGROUND With the wide application of immune checkpoint inhibitors (ICIs) in cancer treatment, immune-related adverse events occur frequently, involving almost all organs and systems. The incidence of ICI-associated arthritis (IA) is unknown. In most cases, IA is not serious and non-lethal. Higher checkpoint inhibitor arthritis disease activity may be associated with cancer progression. Here, we report a severe case of IA with high arthritis disease activity in advanced pulmonary adenocarcinoma, causing permanent withdrawal of pembrolizumab, but the patient remained in complete remission (CR) 20 mo after the development of IA.
CASE SUMMARY An 81-year-old smoking man was admitted to our hospital because of left chest pain for 9 mo. He was finally diagnosed with advanced pulmonary adenocarcinoma, with programmed cell death 1 ligand 1 expression of 70%. The patient responded to pembrolizumab treatment and achieved CR, but IA occurred after the 5th cycle of pembrolizumab administration. Although non-steroidal anti-inflammatory drugs and disease-modifying anti-rheumatic drugs were prescribed, arthralgia and joint swelling occurred. The symptoms of arthritis were further aggravated when immunotherapy was given again after short-term withdrawal. Clinical Disease Activity Index (CDAI) score, a traditional measure of arthritis activity, was 43. Intravenous methylprednisolone was prescribed at 20 mg/d and then tapered over the subsequent 4 wk. The symptoms of arthritis steadily improved and completely resolved 4 mo after withdrawal of pembrolizumab. A recent follow-up in June 2022 revealed satisfactory clinical recovery of arthritis and the patient remained in CR.
CONCLUSION This case report highlights that early recognition of IA and appropriate treatment are critical to improving the outcome of both ICI-arthritis and lung cancer.

Abstract
INTRODUCTION Immune checkpoint inhibitor-induced inflammatory arthritis (ICI-IA) is a relatively new disease entity caused by ICI agents during cancer therapy. Reactive arthritis (ReA) is a well-known disease entity caused by urogenital or gastrointestinal bacterial infection or pneumonia. In this sense, ICI-IA and ReA are both defined by a reaction to a well-specified causal event. As a result, comparing these diseases may help to determine therapeutic strategies. METHODS We compared ICI-IA and ReA with special focus on pharmacological management. Specifically regarding treatment, we conducted a literature search of studies published in the PubMed database. Inclusion criteria were studies on treatment with non-steroidal anti-inflammatory drugs (NSAIDs), glucocorticoids (GC), or disease modifying antirheumatic drugs (DMARDs) in ICI-IA or ReA. During systematic selection, 21 studies evaluating ICI-IA and 14 studies evaluating ReA were included. RESULTS In ICI-IA, prospective and retrospective studies have shown effects of non-steroidal anti-inflammatory drugs (NSAIDs), glucocorticoid (GC), sulfasalazine (SSZ), methotrexate (MTX), hydroxychloroquine (HCQ) and TNFi. In ReA, retrospective studies evaluated NSAIDs and GC. A randomized controlled trial reported the effect of SSZ, and a retrospective study reported the effect of MTX and SSZ in combination with tumor necrosis factor alpha inhibition (TNFi). For both entities, small case reports show treatment effects of interleukin 6 receptor inhibition (IL-6Ri). DISCUSSION This literature review identified both similarities and differences regarding the pathogenesis and clinical features of ReA and ICI-IA. Studies on treatment reported effectiveness of NSAIDs, GC, MTX, SSZ and TNFi in both diseases. Further, small case reports showed effects of IL-6Ri.

Abstract
The development of immune-checkpoint inhibitors (ICIs) has heralded a new era in cancer treatment, enabling the possibility of long-term survival in patients with metastatic disease, and providing new therapeutic indications in earlier-stage settings. As such, characterizing the long-term implications of receiving ICIs has grown in importance. An abundance of evidence exists describing the acute clinical toxicities of these agents, although chronic effects have not been as well catalogued. Nonetheless, emerging evidence indicates that persistent toxicities might be more common than initially suggested. While generally low-grade, these chronic sequelae can affect the endocrine, rheumatological, pulmonary, neurological and other organ systems. Fatal toxicities also comprise a diverse set of clinical manifestations and can occur in 0.4-1.2% of patients. This risk is a particularly relevant consideration in light of the possibility of long-term survival. Finally, the effects of immune-checkpoint blockade on a diverse range of immune processes, including atherosclerosis, heart failure, neuroinflammation, obesity and hypertension, have not been characterized but remain an important area of research with potential relevance to cancer survivors. In this Review, we describe the current evidence for chronic immune toxicities and the long-term implications of these effects for patients receiving ICIs.

Abstract
Rheumatologists increasingly receive consults for patients treated with immune checkpoint inhibitors (ICIs) for cancer. ICIs can cause inflammatory syndromes known as immune-related adverse events (IRAEs). Several rheumatic IRAEs have been reported, including inflammatory arthritis, polymyalgia rheumatica, and myositis. For patients who present with musculoskeletal symptoms while receiving ICI therapy, it is important to have an algorithm for evaluation. The differential diagnosis includes a range of musculoskeletal syndromes, such as crystalline arthritis, mechanical issues, and osteoarthritis, in addition to IRAEs. After diagnosing a rheumatic IRAE, rheumatologists must work with the patient and the oncologist to form a treatment plan. Treatment of IRAEs is guided by severity. Evidence for management is limited to observational studies. Inflammatory arthritis and polymyalgia rheumatica are treated with nonsteroidal antiinflammatory drugs in mild cases, glucocorticoids for moderate-to-severe cases, and sometimes require other disease-modifying antirheumatic drugs. Myositis due to ICIs can be accompanied by myocarditis or myasthenia gravis. Glucocorticoids and withholding the ICI are usually required to treat myositis; some patients with severe myositis require intravenous immunoglobulin or plasmapheresis. Further research is needed to optimize treatment of IRAEs that does not compromise the antitumor effect of ICIs.
