Update on Prevalence of Pain in Patients with Cancer 2022: A Systematic Literature Review and Meta-Analysis. Cancers (Basel) 2023; 15:cancers15030591. [PMID: 36765547 PMCID: PMC9913127 DOI: 10.3390/cancers15030591] [Citation(s) in RCA: 69] [Impact Index Per Article: 69.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 01/13/2023] [Accepted: 01/14/2023] [Indexed: 01/20/2023] Open
Abstract
Experiencing pain and insufficient relief can be devastating and negatively affect a patient's quality of life. Developments in oncology such as new treatments and adjusted pain management guidelines may have influenced the prevalence of cancer pain and severity in patients. This review aims to provide an overview of the prevalence and severity of pain in cancer patients in the 2014-2021 literature period. A systematic literature search was performed using the databases PubMed, Embase, CINAHL, and Cochrane. Titles and abstracts were screened, and full texts were evaluated and assessed on methodological quality. A meta-analysis was performed on the pooled prevalence and severity rates. A meta-regression analysis was used to explore differences between treatment groups. We identified 10,637 studies, of which 444 studies were included. The overall prevalence of pain was 44.5%. Moderate to severe pain was experienced by 30.6% of the patients, a lower proportion compared to previous research. Pain experienced by cancer survivors was significantly lower compared to most treatment groups. Our results imply that both the prevalence of pain and pain severity declined in the past decade. Increased attention to the assessment and management of pain might have fostered the decline in the prevalence and severity of pain.

Abstract
BACKGROUND Esophageal cancer is a highly prevalent cancer associated with low survival, especially among those with advanced disease. Second-line (2L) treatment patterns and related clinical outcomes of patients with advanced esophageal squamous cell carcinoma (advESCC) treated in routine clinical care were examined globally and regionally. METHODS A retrospective, noninterventional study collected physician-provided chart data of patients aged ≥20 years receiving either 2L active systemic therapy or BSC following first-line active therapy for advESCC from 11 countries in Asian and Western regions (September-October 2018). Bivariate analyses examined treatment and outcomes by region. RESULTS AdvESCC patients (Asia = 192; West = 195) were examined, of which 58.1% (Asia n = 101; West n = 124) received active systemic therapy. While regional differences in tumor classification and staging at diagnosis were observed with less advanced tumors in Asia, no regional differences for these characteristics at 2L initiation were reported. Both taxane- and nontaxane-based therapies were used as 2L therapy among Asian and Western patients, although more western than Asian patients received immuno- or targeted therapies (17.0% vs. 3.0%; p = 0.001). Alopecia (10.7%), neutropenia (9.3%), and fatigue (9.3%) were the most-commonly reported adverse events (AEs) in both regions. Significantly higher 2L AE-related emergency room visits (Asia = 22.5% vs. West = 8.0%; p < 0.001) and hospitalizations (Asia = 25.9 ± 31.2 vs. West = 4.7 ± 7.0, p < 0.001) were observed in Asian than in Western patients. No regional differences were reported for response to 2L treatment or the percent of patients who received third-line treatment/died. CONCLUSIONS While regional variations were observed throughout the course of a patient's advESCC journey, disease response and treatment outcomes were similar.

Abstract
BACKGROUND Second-line (2 L) chemotherapies for advanced or metastatic gastric cancer have shown improved survival but there is no commonly accepted standard of care. This study examines real-world patient characteristics, treatment patterns, healthcare resource use (HCRU) and clinical outcomes in this setting. METHODS Retrospective chart reviews were performed at participating institutions from Australia, Canada, Italy and UK for adult patients receiving 2 L treatment for advanced/metastatic disease from January 2013 to July 2015. Data were collected for 12 months or until death. RESULTS Two hundred eighty patients were included, mean age was 60.9 years and 68.9% were male. Half (51.8%) received monotherapy in 2 L, of whom 69.0% received taxanes. Irinotecan monotherapy was common in Australia (30.0% of monotherapy patients) and Canada (43.8%), but infrequent in Italy and UK. Doublet chemotherapy was used in 36.4% of 2 L patients, most commonly fluoropyrimidine + irinotecan. Use of targeted therapies (trastuzumab, ramucirumab) was infrequent except in Italy. Estimated median real-world progression-free survival (rwPFS) and real-world overall survival (rwOS) from the time of 2 L treatment initiation was 3.09 (95% CI: 2.76-3.68) and 6.54 (5.29-7.76) months, respectively, and estimated 12-month rwPFS and rwOS rate was 8 and 26%, respectively. Only a minority (26.8%) of patients were hospitalized during the follow-up period, with the lowest hospitalization in Italy (16.7%). Laboratory and imaging tests were performed for 93.2 and 70.4%, respectively. CONCLUSIONS About half of patients received monotherapy as 2 L chemotherapy for advanced/metastatic gastric cancer and a third received doublets. Real-world clinical outcomes for 2 L treatment are poor and HCRU is considerable.

Abstract
Objective: Little evidence is available on the management of patients with metastatic and/or unresectable gastric cancer (mGC) after the failure of first-line treatment. This study presents real-world data on characteristics and treatment patterns of patients with mGC in Russia. Methods: Eligible patients were ≥18 years old, diagnosed with mGC ≥ January 1, 2012, received first-line chemotherapy followed by second-line chemotherapy or best supportive care (BSC), had ≥3 months of follow-up after the start of second-line chemotherapy or BSC (except in cases of death), and had not participated in a clinical trial. Data were summarized using descriptive statistics. Results: A total of 88 physicians provided data from 202 charts. Mean age at mGC diagnosis was 53.7 (standard deviation: 11.2) years; 70.8% of patients were male. Reasons for first-line treatment discontinuation included disease progression (50.5%) and adverse events/toxicity (39.1%). There were 52 unique treatment regimens prescribed in second-line; capecitabine (14.5%), paclitaxel (9.3%), and capecitabine + oxaliplatin (8.7%) were the most frequent. Reasons for second-line treatment discontinuation included disease progression (39.8%) and patient refusal to continue (37.5%). During 2nd-line treatment, the most common treatment-related symptoms were nausea/vomiting (75.0%), while pain (73.8%) was the most common disease-related symptom. Antiemetics (63.4%), chemotherapy (61.6%), non-narcotic analgesics (48.3%), endoscopy (45.9%), and nutritional support (35.5%) were most frequently used as supportive care. Conclusions: Second-line treatment patterns for patients with mGC in Russia are heterogeneous. Results of this study indicate the need for more intensive implementation of the most active regimens in second-line treatment of mGC according to international and national guidelines.

Abstract
Gastric cancer (GC) and gastroesophageal junction cancers (GEJCs) are the third leading cause of cancer-related death worldwide. Although several studies have evaluated the epidemiology and management of GC and GEJC, to our knowledge, no global estimates of the economic burden of GC and GEJC have yet been reported. This targeted literature review was conducted to summarise the epidemiology and management of GC and GEJC and to estimate its global economic and humanistic burden. The incidence of GC and GEJC is highest in Eastern Asia, several South and Central American countries and Central and Eastern Europe and lowest in North America and Africa. Prognosis is generally poor; the global 5-year survival rate is 5%-10% in advanced stages. Patients with GC and GEJC have more severe symptoms compared with patients with other cancers, and health-related quality of life (HRQoL) worsens as the disease progresses. Given the rapid progression of GC and GEJC at advanced stages, chemotherapy, despite its toxicity, improves HRQoL compared with best supportive care. The costs of GC/GEJC are generally higher than for other cancers; in the US, the average annual cost per patient between 1998 and 2003 was 46,501 USD, compared with 29,609 USD and 35,672 USD for colorectal and lung cancer, respectively. Based on the 2012 incidence data and average costs per patient, estimates of the annual financial burden of GC and GEJC revealed great regional differences. Japan and Iran had the highest (8,492 million USD) and lowest (27 million USD) costs for 2017, respectively, while the estimate for the US was 3,171 million USD. The overall annual cost of GC and GEJC estimated for 2017 in a geographic area including Europe (France, Germany, Italy, Spain and the UK), Asia (Iran, Japan and China), North America (Canada and the US) and Australia was 20.6 billion USD.

Abstract
PURPOSE In Brazil, patients with gastric cancer have not been systematically followed-up and evaluated, thus data regarding patterns of care and outcomes are scarce or missing. The objective of this study was to evaluate patterns of care of advanced gastric cancer in standard practice in Brazil. METHODS This was an observational, multicenter, retrospective study, which included patients with metastatic and/or unresectable gastric cancer (MGC) who underwent at least one line of treatment. RESULTS We analyzed data on 155 patients diagnosed with MGC, most are men (57.4%), with mean age of 61.9 years at diagnosis, with 99 (63.9%) from the public healthcare system and 56 (36.1%) from the private setting. Platinum- and/or fluoropyrimidine-containing regimens prevailed as first-line therapy, while irinotecan was the most used regimen in the second and in the third lines. More than 40% of patients underwent only one line of systemic therapy, of which around 40% either died during the treatment or went on to best supportive care (BSC) only. The remaining patients received further treatment lines. A fifth of the patients in the study died within two months after discontinuation of the first-line treatment. Adverse events, use of concomitant medications, support procedures, outpatient visits, and hospitalizations were reported for most patients, especially in the first and second lines of treatment and during exclusive BSC. CONCLUSIONS Survival during or after the first-line chemotherapy remains poor among patients with MGC. Adverse events and health resource use were common in the first and second lines of treatment and in exclusive BSC. These results suggest that there is space for improvement in the treatment of MGC in Brazil.

Survival in Advanced Esophagogastric Adenocarcinoma Improves With Use of Multiple Lines of Therapy: Results From an Analysis of More Than 500 Patients. Clin Colorectal Cancer 2018; 17:223-230.

Abstract
BACKGROUND Although progress has been made in the molecular stratification of esophagogastric adenocarcinoma, the outlook for advanced disease remains poor. The present evaluation of over 500 patients treated at a single European high-volume tertiary center during a 6-year period gives important information on current and developing "real-world" treatment patterns and outcomes. RESULTS The overall survival for the whole cohort was 11.5 months, with a range of treatments used in first-, second-, and third-line settings. Treatment with sequential lines of therapy was associated with better outcomes, although only 39% and 14% of patients subsequently received treatment in the second- and third-line setting, respectively. Treatment within a therapeutic clinical trial was associated with significantly improved survival. CONCLUSION At present, a substantial proportion of patients with advanced esophagogastric adenocarcinoma will not proceed beyond first-line therapy, and for this group refinement of initial systemic therapies are required to improve outcomes. Although a number of established first- and second-line treatment options are now available, the therapeutic landscape of the disease continues to change, most notably in the application of immunotherapy and increasing interest in establishing evidence-based interventions in the third-line setting and beyond. A small but growing proportion of patients will benefit from sequential treatment approaches incorporating multiple lines of therapy, and improved selection of such patients will be a key challenge for clinicians moving forwards. Data such as these provide an overview of current treatment patterns and outcomes which can be used to inform planning of future research effectively within existing treatment frameworks.

Abstract
BACKGROUND Little evidence is available on the management and cost of treating patients with advanced or metastatic gastric cancer (GC). This study evaluates patient characteristics, treatment patterns, and resource utilization for these patients in Mexico. METHODS Data were collected from three centers of investigation (tertiary level). Patients were ≥18 years of age, diagnosed between 1 January 2009 and 1 January 2015, had advanced or metastatic GC, received first-line fluoropyrimidine/platinum, and had ≥3 months follow-up after discontinuing first-line treatment. Data were summarized using descriptive statistics. RESULTS The study sample totaled 180. Patients' mean age was 57.2 years (±12.4) and 57.0% were male; 151 (83.9%) patients received second-line chemotherapy. A total of 16 and 19 regimens were identified in first- and second-line therapy. Of the sample, 51 (28.3%) received third-line therapy, and <10% received more than three lines of active chemotherapy. Supportive care received in first- and second-line chemotherapy, included pain interventions (12.2 and 7.9%), nutritional support (3.3 and 1.3%), radiotherapy (6.1 and 16.6%), and transfusions (13.3 and 10.6%), respectively. Using Mexican Institute of Social Security (IMSS) tariffs, the average total cost per patient-month in first- and second-line therapy was US$1230 [95% confidence interval (CI) 1034-1425] and US$1192 (95% CI 913-1471), respectively. Administration and acquisition of chemotherapy comprised the majority of costs. CONCLUSIONS This study shows considerable variation in first- and second-line chemotherapy regimens of patients with advanced or metastatic GC. Understanding GC treatment patterns in Mexico will help address unmet needs.

Abstract
BACKGROUND Gastric cancer is one of the leading causes of cancer-related deaths in both sexes worldwide, especially in Eastern Asia. This study aimed to estimate the economic burden of advanced gastric cancer (AGC) in Taiwan. METHODS The costs of AGC in 2013 were estimated using resource use data from a chart review study (n = 122 with AGC) and national statistics. Annual per-patient costs, where patients' follow-up periods were adjusted for, were estimated with 82 patients who had complete resource use data. The costs were composed of direct medical costs, direct non-medical costs (healthcare travel and caregiver costs), morbidity costs, and mortality costs. Relevant unit costs were retrieved mainly from literature and national statistics, and applied to the resource use data. A broad definition of morbidity and mortality costs was employed to value the productivity loss in patients with unpaid employment, economically inactive and unemployed as well as the life years after the age of retirement. Their narrow definitions were also used in sensitivity analyses, using age- and/or sex-specific employment rates. Forgone future earnings/productivity loss were discounted at 3%. Annual per-patient costs were projected to estimate the total costs of AGC at the national level with an estimated number of patients with AGC (N = 2611) in Taiwan in 2013. RESULTS The mean age of the 82 patients was 59.3 (SD: 11.9) years, and 67.1% were male. Per-patient costs were US$26,431 for direct medical costs, US$4669 for direct non-medical costs, US$5758 for morbidity costs, and US$145,990 for mortality costs (per death). These per-patient costs were projected to incur total AGC costs of US$423 million at the national-level. Mortality costs accounted for 77.3% of the total costs, followed by direct medical costs (16.3%), morbidity costs (3.6%), and direct non-medical costs (2.9%). CONCLUSION AGC was found to exert a significant economic burden in Taiwan, incurring US$423 million in 2013. This represents about 0.08% of the Taiwanese economy. Mortality costs appeared to be the single greatest contributor to the burden, followed by direct medical costs. Early detection and providing effective treatments will help to reduce its burden on patients, caregivers and society as a whole. A poster of this study was presented at the 2016 American Society of Clinical Oncology (ASCO) Gastrointestinal Cancers Symposium in San Francisco, CA, USA.
