Barriers and explanatory mechanisms in diagnostic delay in four cancers - A health-care disparity?

Ranking of Health Problems and Prioritization of Cancer Education Topics by African American Communities in South Carolina

Despite landmark breakthroughs in cancer research, African American adults (AA) bear the highest cancer burden compared to other racial groups in the United States (US). AA adults have twice the likelihood of dying from prostate and uterine cancers compared to White adults, suggesting that there are fundamental issues yet to be addressed when developing and implementing cancer-preventative programs for AA communities. Community-based participatory research (CBPR) empowers community members to identify and prioritize their health problems and preferred strategies to tackle these issues. In alignment with the CBPR approach, the South Carolina Cancer Disparities Research Center (SC CADRE) undertook a study to inform cancer research priorities and interventions. A survey designed by the SC CADRE team to assess perceptions about health problems (cancer risk factors), prioritization of cancer education topics, and attitudes related to cancer prevention was completed by predominantly AA community members in South Carolina (N = 179). Participants had a mean age of 51.59 ± 16.53 years; the majority were AA (72.49%), females (76.44%), had bachelor's/graduate degrees (66.29%), and were from the Lowcountry coastal region of the state (85.26%). Obesity emerged as the greatest health concern, followed by poor diet and low physical activity. The top three priorities for cancer education were to learn about causes of cancer, strategies for healthy eating, and how to access healthcare. These findings could inform cancer education and intervention programs to address the top priority health needs identified by AA communities in South Carolina. They may also be relevant in other states, especially in rural southern parts of the USA.

Successful Preoperative Radiotherapy for Neglected Shoulder Liposarcoma: A Retrospective Case Report

This study examines a unique case of a 61-year-old male with a 5-year history of a progressively growing mass above his right shoulder, diagnosed as a dedifferentiated pleomorphic liposarcoma. Using computerized tomography-guided core needle biopsy, the tumour was identified as intermediate to high grade. Surgical removal required preoperative radiotherapy to reduce the size of the tumour. Several unique characteristics set apart this particular case of liposarcoma: its substantial size, its unpredictable growth pattern, its absence of metastasis, and notably, its prolonged period of being untreated. This case report outlines the clinical background, diagnostic procedures, and treatment modalities employed in managing this condition, emphasizing a localized dual therapy approach combining radiotherapy and surgery. Emphasis is placed on distinguishing liposarcoma from lipoblastoma, a benign adipocyte tumour, to facilitate accurate diagnosis and appropriate treatment selection. The positive result achieved in this case could provide valuable insights for the future treatment and management of similarly sized aggressive tumours.

Association between the Environmental Quality Index and Textbook Outcomes Among Medicare Beneficiaries Undergoing Surgery for Early-Stage Pancreatic Adenocarcinoma

BACKGROUND

Access to high-quality cancer care is affected by environmental exposures and structural inequities. This study sought to investigate the association between the environmental quality index (EQI) and achievement of textbook outcomes (TO) among Medicare beneficiaries over the age of 65 who underwent surgical resection for early-stage pancreatic adenocarcinoma (PDAC).

METHODS

Patients diagnosed with early-stage PDAC from 2004 to 2015 were identified using the SEER-Medicare database and combined with the US Environmental Protection Agency's EQI data. High EQI category indicated poor environmental quality, whereas low EQI indicated better environmental conditions.

RESULTS

A total of 5,310 patients were included, of which 45.0% (n = 2,387) patients achieved TO. Median age was 73 years and more than half were female (n = 2,807, 52.9%), married (n = 3,280, 61.8%), and resided in the Western region of the US (n = 2,712, 51.1%). On multivariable analysis, patients residing in moderate and high EQI counties were less likely to achieve a TO (referent: low EQI; moderate EQI: OR 0.66, 95% CI 0.46-0.95; high EQI: OR 0.65, 95% CI 0.45-0.94; p < 0.05). Increasing age (OR 0.98, 95%CI 0.97-0.99), racial minorities (OR 0.73, 95% CI 0.63-0.85), having a Charlson co-morbidity index > 2 (OR 0.54, 95%CI 0.47-0.61) and stage II disease (OR 0.82, 95%CI 0.71-0.96) were also associated with not achieving a TO (all p < 0.001).

CONCLUSION

Older Medicare patients residing in moderate or high EQI counties were less likely to achieve an "optimal" TO after surgery. These results demonstrate that environmental factors may drive post-operative outcomes among patients with PDAC.

Symptoms and signs of urogenital cancer in primary care

BACKGROUND

Urogenital cancers are common, accounting for approximately 20% of cancer incidence globally. Cancers belonging to the same organ system often present with similar symptoms, making initial management challenging. In this study, 511 cases of cancer were recorded after the date of consultation among 61,802 randomly selected patients presenting in primary care in six European countries: a subgroup analysis of urogenital cancers was carried out in order to study variation in symptom presentation.

METHODS

Initial data capture was by completion of standardised forms containing closed questions about symptoms recorded during the consultation. The general practitioner (GP) provided follow-up data after diagnosis, based on medical record data made after the consultation. GPs also provided free text comments about the diagnostic procedure for individual patients.

RESULTS

The most common symptoms were mainly associated with one or two specific types of cancer: 'Macroscopic haematuria' with bladder or renal cancer (combined sensitivity 28.3%), 'Increased urinary frequency' with bladder (sensitivity 13.3%) or prostatic (sensitivity 32.1%) cancer, or to uterine body (sensitivity 14.3%) cancer, 'Unexpected genital bleeding' with uterine cancer (cervix, sensitivity 20.0%, uterine body, sensitivity 71.4%). 'Distended abdomen, bloating' had sensitivity 62.5% (based on eight cases of ovarian cancer). In ovarian cancer, increased abdominal circumference and a palpable tumour also were important diagnostic elements. Specificity for 'Macroscopic haematuria' was 99.8% (99.7-99.8). PPV > 3% was noted for 'Macroscopic haematuria' and bladder or renal cancer combined, for bladder cancer in male patients. In males aged 55-74, PPV = 7.1% for 'Macroscopic haematuria' and bladder cancer. Abdominal pain was an infrequent symptom in urogenital cancers.

CONCLUSIONS

Most types of urogenital cancer present with rather specific symptoms. If the GP considers ovarian cancer, increased abdominal circumference should be actively determined. Several cases were clarified through the GP's clinical examination, or laboratory investigations.

Duration of the patient interval in breast cancer and factors associated with longer delays in low-and middle-income countries: A systematic review with meta-analysis

OBJECTIVE

Breast cancer survival is lower in low- and middle-income countries (LMICs) partially due to many women being diagnosed with late-stage disease. The patient interval refers to the time elapsed between the detection of symptoms and the first consultation with a healthcare provider and is considered one of the core indicators for early diagnosis and treatment. The goal of the current research was to conduct a meta-analysis of the duration of the patient interval in LMICs and investigate the socio-demographic and socio-cultural factors related to longer delays in presentation.

METHODS

We conducted a systematic review with meta-analysis (pre-registered protocol CRD42020200752). We searched seven information sources (2009-2022) and included 50 articles reporting the duration of patient intervals for 18,014 breast cancer patients residing in LMICs.

RESULTS

The longest patient intervals were reported in studies from the Middle East (3-4 months), followed by South-East Asia (2 months), Africa (1-2 months), Latin America (1 month), and Eastern Europe (1 month). Older age, not being married, lower socio-economic status, illiteracy, low knowledge about cancer, disregarding symptoms or not attributing them to cancer, fear, negative beliefs about cancer, and low social support were related to longer delays across most regions. Longer delays were also related to use of alternative medicine in the Middle East, South-East Asia, and Africa and distrust in the healthcare system in Eastern Europe.

CONCLUSIONS

There is large variation in the duration of patient intervals across LMICs in different geographical regions. Patient intervals should be reduced and, for this purpose, it is important to explore their determinants taking into account the social, cultural, and economic context.

Diagnostic Delay in Paediatric Inflammatory Bowel Disease-A Systematic Investigation

Diagnostic delays (time from the first symptoms to diagnosis) are common in inflammatory bowel disease (IBD) and may lead to worse disease progression and treatment outcomes. This study aimed to determine the duration of diagnostic delays (DD) and to explore associated factors in a cohort of children with IBD in New Zealand. In this study, patients with IBD diagnosed as children and their parents/caregivers completed questionnaires on the patients’ medical history, diagnostic experience, and demographic characteristics. The parent/caregiver questionnaire also included the Barriers to Care Questionnaire (BCQ). Patients’ healthcare data was reviewed to summarise the history of clinical visits and determine symptoms. Total DD, healthcare DD, patient DD and parent DD were derived from the primary dataset. Factors associated with the different types of DD were explored with a series of simple linear and logistical ordinal regressions. A total of 36 patients (Crohn’s disease 25, ulcerative colitis 10; male 17) were included. They were diagnosed at a median age of 12 years (interquartile range (IQR) 10−15 years). Total healthcare delay (from first healthcare visit to formal diagnosis) was median (IQR) 15.4 (6.5−34.2) months. The median (IQR) specialist-associated delay was 4.5 (0−34) days. Higher household income was associated with shorter healthcare delay (p < 0.018), while lower overall BCQ scores (indicating more barriers experienced) were associated with longer total healthcare DD. Higher scores in each subscale of BCQ (Skills; Pragmatics; Expectations; Marginalization; Knowledge and Beliefs) were also significantly associated with shorter total healthcare delay (p < 0.04). This study found substantial diagnostic delays in paediatric patients with IBD and identified significant associations between longer total healthcare diagnostic delays and overall household income and higher self-reported barriers to accessing healthcare.

Impact of Race/Ethnicity and County-Level Vulnerability on Receipt of Surgery Among Older Medicare Beneficiaries With the Diagnosis of Early Pancreatic Cancer

BACKGROUND

Patients can experience barriers and disparities to access high-quality cancer care. This study sought to characterize receipt of surgery and chemotherapy among Medicare beneficiaries with a diagnosis of early-stage pancreatic adenocarcinoma cancer (PDAC) relative to race/ethnicity and social vulnerability.

METHODS

The Surveillance, Epidemiology, and End Results (SEER)-Medicare database was used to identify patients with a diagnosis of early-stage (stage 1 or 2) PDAC between 2004 and 2016. Data were merged with the CDC's Social Vulnerability Index (SVI) at the beneficiary's county of residence. Multivariable, mixed-effects logistic regression was used to assess the association of SVI with resection.

RESULTS

Among 15,931 older Medicare beneficiaries with early-stage PDAC (median age, 77 years; interquartile range [IQR], 71-82 years), the majority was White (n = 12,737, 80.0 %), whereas a smaller subset was Black or Latino (n = 3194, 20.0 %) A minority of patients was more likely to live in highly vulnerable communities (low SVI: white [90.5 %] vs minority [9.5 %] vs high SVI: white [71.9 %] vs minority [28.1 %]; p < 0.001). Use of resection for early-stage PDAC was lowest among the patients who resided in high-SVI areas (low [38.0 %] vs average [34.3 %] vs high [31.9 %]; p < 0.001). The minority patients were less likely to undergo resection than the White patients (no resection: white [64.1 %] vs minority [70.7 %]; p < 0.001). The median SVI was higher among the patients who underwent resection (57.6; IQR, 36.0-81.0) than among those who did not (60.4; IQR, 41.9-84.3), and increased SVI resulted in a decline in the likelihood of resection (SVI trend: OR, 0.98; 95 % confidence interval [CI], 0.97-1.00), especially among the minority patients. Minority patients from high-SVI counties had markedly lower odds of preoperative chemotherapy than minority patients from a low-SVI neighborhood (OR, 0.62; 95 % CI, 0.52-0.73).

CONCLUSIONS

Older Medicare beneficiaries with early-stage PDAC residing in counties with higher social vulnerability had lower odds of undergoing pancreatic resection, which was more pronounced among minority versus older White Medicare beneficiaries.

Improving Care for Patients With Stage III or IV NSCLC: Learnings for Multidisciplinary Teams From the ACCC National Quality Survey

PURPOSE

Insufficient characterization of the optimal multidisciplinary team and lack of understanding of barriers to quality care are unmet needs in the management of stage III or IV non-small-cell lung cancer (NSCLC). A national survey was conducted to inform the design and execution of process improvement plans and address identified barriers.

METHODS

A steering committee of multidisciplinary specialists and representation from patient advocacy collaborated for a comprehensive, double-blind, web-based survey (January-April 2019) to obtain insights on care delivery for patients with advanced NSCLC in a diverse set of US community cancer programs.

RESULTS

Overall, 639 responses (160 unique cancer programs across 44 US states) were included; 41% (n = 261) of respondents indicated an absence of a thoracic multidisciplinary clinic in their cancer program. Engagement in shared decision making was significantly associated with the presence of navigation and radiation oncology disciplines (P ≤ .04); 19.2% and 33.3% of respondents belonged to cancer programs with no lung cancer screening and no protocol for biomarker testing, respectively. The frequency of tumor board meetings negatively correlated with time to complete disease staging (P = .03); the average time to first therapeutic intervention in newly diagnosed patients was 4 weeks. The most challenging barriers to quality care included insufficient quantity of biopsy material for biomarker testing, lack of primary care provider referrals, and diagnostic costs.

CONCLUSION

Improving the quality of advanced NSCLC care, including optimization of a multidisciplinary team framework, may surmount barriers to care coordination, diagnosis and staging, and treatment planning, consequently improving adherence to evolving standards of care.

Sex-based differences in time to surgical care among pancreatic cancer patients: A national study of Medicare beneficiaries

INTRODUCTION

The objective of this study was to characterize time from cancer symptoms to diagnosis and time from diagnosis to surgical treatment among patients undergoing pancreatectomy for cancer.

METHODS

Medicare beneficiaries who underwent pancreatectomy for cancer between 2013 and 2017 were identified using the 100% Medicare Inpatient Standard Analytic Files. Mixed effects negative binomial regression models were utilized to determine which factors were associated with the number of weeks to diagnosis and pancreatic resection.

RESULTS

Among 7647 Medicare beneficiaries, two-thirds (n = 5127, 67%) had symptoms associated with a pancreatic cancer diagnosis before surgery. Median time from the first symptom to diagnosis was 6 weeks (IQR: 1-25) and the median time from diagnosis to surgery was 4 weeks (IQR: 2-15). In risk-adjusted models, female patients had 13% longer waiting times from identification of a related symptom to pancreatic cancer diagnosis (OR = 1.13, 95% CI: 1.05-1.21) and 12% longer waiting times from diagnosis to surgery (OR = 1.12, 95% CI: 1.07-1.18). Older age was associated with 10% longer waiting times from symptom identification to diagnosis (p < .0001).

CONCLUSIONS

Female and older patients had longer wait times between symptom presentation and pancreatic cancer diagnosis. Sex-based disparities in cancer care need to be recognized and addressed by policymakers and health care institutions.

Sociodemographic and clinical profile of geriatric patients with cervical cancer-An audit from a tertiary cancer center in India

BACKGROUND AND AIM

Cervical cancer is a major health problem among the female population worldwide. Its incidence among the elderly group of patients seems to be increasing. Sociodemographic along with clinical profile of patients is the first step in planning preventive and curative measures; we thus conducted a retrospective analysis of demographic and clinical profile of elderly patients suffering from cervical cancer visiting at our institute.

PATIENTS AND METHODS

Records of 88 elderly patients (age> =65 years) suffering from cervical cancer from the year 2011 to 2014 were analyzed for a sociodemographic profile, symptoms, histology, and staging. Fisher's exact test was applied using R software (version 3.5.2) for statistical analysis.

RESULTS

The median age of the cohort was 74 years. The majority of patients were from a rural background and were nonsmokers. All patients were multiparous. The most common presenting symptoms were discharge, bleeding from vagina and pain in the abdomen; present in 45 (51.13%), 25 (28.40%) and 18 (20.45%) patients, respectively. 78 (88.63%) patients' had advanced stage (II, III, IV) at the time of presentation while the number of cases diagnosed at early stage were only 10 (11.36%). 69% had associated comorbidities. Prolonged duration of symptoms was also found to be associated with higher stage (P < 0.05).

CONCLUSION

The study brings forth the background profile of the elderly patients suffering from cervical cancer. Since the majority of patients present in an advanced stage of disease appropriate preventive steps and also the possibility of initiating screening measures should be sought among an elderly group of cervical cancer patients.
