Financial Burden of Hepatocellular Carcinoma Screening in Patients With Cirrhosis

BACKGROUND

The overall value of hepatocellular carcinoma screening is defined by the balance of benefits and harms. Studies have only reported physical harms with none describing financial harms.

METHODS

We conducted a multicenter pragmatic randomized clinical trial of hepatocellular carcinoma screening outreach among 2872 patients with cirrhosis from March 2018 to April 2021. Patients with positive or indeterminate results and matched patients with negative results completed surveys at baseline and at follow-up measuring financial harms via Cancer Self-Administered Questionnaire and financial burden via Comprehensive Score for Financial Toxicity Functional Assessment of Chronic Illness Therapy. Univariable and multivariable longitudinal regression analyses were performed to compare changes in financial harms across groups: true positive, true negative, false positive, and indeterminate. Semistructured interviews were conducted in a subset of patients, sampled by center and test result.

RESULTS

Of 311 patients who completed at least 1 follow-up survey (75% response rate), 37 had true positive, 133 true negative, 64 false positive, and 77 indeterminate results. Financial harms increased in true positive and false positive patients with no significant changes noted among those with true negative or indeterminate results. At follow-up, 21.8% of patients reported moderate-severe financial burden, which was not significantly associated with test results. Semistructured interviews revealed variation in the frequency and severity of financial harms based on test results, with increased harm in those with false positive results.

CONCLUSIONS

Financial harms of hepatocellular carcinoma screening vary by test result and can pose a barrier that must be considered when determining the optimal screening program.

Hepatocellular carcinoma surveillance may be associated with potential psychological harms in patients with cirrhosis

BACKGROUND AND AIMS

The value of HCC surveillance is determined by the balance between benefits and harms; however, no studies have enumerated psychological harms.

APPROACH AND RESULTS

We fielded surveys measuring psychological harms to patients with cirrhosis in a multicenter randomized trial of HCC surveillance outreach. All patients with positive or indeterminate surveillance results and matched patients with negative results were invited to complete surveys measuring (1) depression through the Patient Health Questionnaire-ninth version, (2) anxiety through State-Trait Anxiety Inventory, (3) HCC-specific worry through Psychological Consequences Questionnaire, and (4) decisional regret. Patients were classified into 4 groups: true positive (TP), false positive (FP), indeterminate, and true negative (TN). Multivariable longitudinal regression analysis using the generalized estimating equation method was performed to compare the means of measures across groups. We conducted 89 semistructured interviews in a subset of patients stratified by health system and test results. Of 2872 patients in the trial, 311 completed 1+ follow-up survey (63 FP, 77 indeterminate, 38 TP, and 133 TN). Moderate depression decreased in TN patients, increased in TP, and had intermittent but mild increases in those with FP and indeterminate results. High anxiety temporarily increased in patients with TP results but resolved over time and was stable in those with FP and indeterminate results. Decisional regret was low and did not differ across groups. In semistructured interviews, patients reported apprehension, anxiety, emotional distress, and coping related to HCC surveillance.

CONCLUSIONS

Psychological harms of HCC surveillance appear mild but differ by test result. Future research should determine the impact of psychological harms on the value of HCC surveillance programs.

Unmet Needs and Receipt of Supportive Care Services in Head and Neck Cancer Patients Prior to Oncologic Treatment: A Prospective, Cross-Sectional Pilot Study

OBJECTIVE

To characterize the supportive care (SC) needs and receipt of SC services among head and neck cancer (HNC) patients prior to oncologic treatment and to explore the influence of social determinants of health on these outcomes.

MATERIALS AND METHODS

Newly diagnosed HNC patients were surveyed via telephone prior to oncologic treatment between 10/2019 and 1/2021 using a prospective, cross-sectional, bi-institutional, pilot study design. The primary study outcome was unmet SC needs (Supportive Care Needs Survey-Short Form34 [SCNS-SF34]). Hospital type (university- vs county safety-net) was explored as an exposure. Descriptive statistics were performed using STATA16 (College Station, TX).

RESULTS

Among 158 potentially eligible patients, 129 were successfully contacted, 78 met the study criteria, and 50 completed the survey. The mean age was 61, 58% exhibited clinical stage III-IV disease, and 68% and 32% were treated at the university and county safety-net hospital, respectively. Patients were surveyed a median of 20 days after their first oncology visit and 17 days prior to initiation of oncology treatment. They had a median of 24 total needs (11 were met and 13 were unmet) and preferred to see a median of 4 SC services but received care from none. County safety-net patients had comparatively more unmet needs than university patients (14.5 vs 11.5, P = .04).

CONCLUSION

Pretreatment HNC patients at a bi-institutional academic medical center report a high number of unmet SC needs with corollary poor receipt of available SC services. Novel interventions to address this significant gap in care are needed.

Multicenter Randomized Clinical Trial of a Mailed Outreach Strategy for Hepatocellular Carcinoma Surveillance

BACKGROUND

The effectiveness of hepatocellular carcinoma (HCC) surveillance is mitigated by underuse in clinical practice, highlighting a need for interventions. We evaluated the effectiveness of mailed HCC surveillance outreach to promote HCC surveillance in patients with cirrhosis.

METHODS

We conducted a multicenter pragmatic randomized clinical trial comparing mailed outreach for surveillance ultrasound (n = 1436) and usual care with visit-based surveillance (n = 1436) among patients with cirrhosis at 3 health systems (tertiary care referral center, safety net health system, and Veterans Affairs medical center) from April 2018 to December 2019. The primary outcome of this interim analysis was guideline concordant semiannual HCC surveillance over a 12-month period and a secondary outcome was proportion time covered by surveillance. All patients were included in intention-to-screen analyses.

RESULTS

Compared with usual care, the outreach arm had significantly higher semiannual surveillance (35.1% vs 21.9%) and lower no-surveillance (29.8% vs 43.5%) (P < .001), resulting in significant increases in the proportion of time covered by surveillance (41.3% vs 31.0%; P < .001). The intervention increased HCC surveillance across most predefined subgroups; however, there were site-level differences in the intervention effect, with significant increases in semiannual surveillance at the Veterans Affairs and safety net health systems but not at the tertiary care referral center.

CONCLUSIONS

Mailed outreach significantly increased semiannual HCC surveillance vs usual care in patients with cirrhosis, with a consistent intervention effect across most examined subgroups. Continued follow-up is ongoing to determine if these increases in surveillance translate into improved downstream outcomes includi.ng early HCC detection and curative treatment receipt.

A robust multisyringe system for process flow analysis. Part II. A multi-commuted injection system applied to the photometric determination of free acidity and iron(III) in metallurgical solutions

A new software-controlled volume-based system for sample introduction in process flow injection analysis was developed. By using a multi-syringe burette coupled with one or two additional commutation valves, the multi-commuted injection of precise sample volumes was accomplished. Characteristics and performance of the injection system were studied by injecting an indicator in a buffered carrier. Three configurations were implemented in order to achieve two different tasks: the single injection of a sample in a two- or three-channels manifold, and the dual injection into different streams. The two channel flow system using the single injection was applied to the determination of free acidity in diluted samples containing high levels of iron(III), by employing the single point titration methodology. The precipitation of ferric hydroxide was prevented using the ammonium and sodium salts of oxalate and acetate as buffer titrant. Methyl Red was employed as indicator. The procedure allows determination of acid concentration in solutions with a Fe(III)/H+ molar ratio up to 0.2. Samples with higher Fe(III)/H+ molar ratios were spiked with a known strong acid at dilution. The three-channel configuration was applied to the determination of ferric ions, using, as reagent, a merging mixture of sulfuric acid and potassium thiocyanate. The double injection system was implemented in series in a single (three-channel) manifold in such a way that a different injection volume and a changed reagent were used for each analyte. It was applied to the separated or sequential determination of free acidity and ferric ions. In this configuration, iron(III) was determined using 0.5-0.7% (w/v) sodium salicylate solution as reagent. The systems can operate at up to 100, 84 and 78 injections per hour, respectively. Determinations on synthetic and process samples compared well with the reference values and procedures. Recoveries of 95-102% with a maximum RSD value of 5.4% were found for acidity. The respective values obtained for iron determinations were 96-105% and 4.3%.

Simultaneous multiwavelength spectrophotometric quantitation of active components in analgesic formulations. Comparative study of three calculation methods

This work deals with the UV spectrophotometric quantitation of a mixture of compounds with overlapped spectra. The mixture spectrum is resolved by use of three computational programs based on different algorithms, namely Multicomponent Analysis (commercial software available from Hewlett-Packard), MULTIC (relying on multiple regression analysis) and SIMPLEX. The results obtained for mixtures of acetylsalicylic acid, acetaminophen and caffeine in commercial analgesic formulations, are compared.
