Characteristics of patients with liver tumors deemed ineligible for enrollment on Children's Oncology Group trial AHEP1531: An opportunity to expand inclusion criteria and improve outcome

BACKGROUND

Specific patients with hepatoblastoma (HB) and hepatocellular carcinoma (HCC) do not meet eligibility criteria for Children's Oncology Group (COG) trials, limiting an understanding of how comorbidities affect the outcome. We define such a population for future-focused care improvements.

METHODS

A questionnaire was sent to COG institutional principal investigators to obtain anonymized data regarding patients with a liver tumor diagnosis not enrolled on AHEP1531 due to ineligibility by trial criteria or other reasons (excluding parent/patient preference).

RESULTS

Responses received for 55 patients (38 HB, 4 HCC, and 13 not reported) included 12 excluded from further analysis due to various factors, including lack of additional information. Five patients were eligible but not enrolled due to pandemic-related staffing issues (n = 1) or the best interest of the patient (physician preference, n = 1; risk for poor tolerance of chemotherapy, n = 1; not specified, n = 2). The remaining 38 patients included 1 ineligible due to a prior malignancy, 9 due to performance status, and 4 due to timing requirements. Thirty-five of 38 patients were ineligible due to organ function criteria (pulmonary/oxygen requirement, n = 25; renal, n = 10; liver, n = 4; cardiac, n = 3). Seven patients were ineligible due to two or more organ function criteria. Twenty-five of 38 patients were reported to have a preexisting condition including 4 patients with trisomy 18.

CONCLUSIONS

Patients with HB, and potentially HCC, who are ineligible for COG trials are primarily patients with an oxygen requirement and/or renal insufficiency, often associated with preexisting congenital conditions. Such patients would benefit from future studies to improve outcomes.

Phenotypic severity scoring system and categorisation for prune belly syndrome: application to a pilot cohort of 50 living patients

OBJECTIVE

To design a novel system of scoring prune belly syndrome (PBS) phenotypic severity at any presenting age and apply it to a large pilot cohort.

PATIENTS AND METHODS

From 2000 to 2017, patients with PBS were recruited to our prospective PBS study and medical records were cross-sectionally analysed, generating individualised RUBACE scores. We designed the pragmatic RUBACE-scoring system based on six sub-scores (R: renal, U: ureter, B: bladder/outlet, A: abdominal wall, C: cryptorchidism, E: extra-genitourinary, generating the acronym RUBACE), yielding a potential summed score of 0-31. The 'E' score was used to segregate syndromic PBS and PBS-plus variants. The cohort was scored per classic Woodard criteria and RUBACE scores compared to Woodard category.

RESULTS

In all, 48 males and two females had a mean (range) RUBACE score of 13.8 (8-25) at a mean age of 7.3 years. Segregated by phenotypic categories, there were 39 isolated PBS (76%), six syndromic PBS (12%) and five PBS-plus (10%) cases. The mean RUBACE scores for Woodard categories 1, 2, and 3 were 20.5 (eight patients), 13.8 (25), and 10.6 (17), respectively (P < 0.001).

CONCLUSIONS

RUBACE is a practical, organ/system level, phenotyping tool designed to grade PBS severity and categorise patients into isolated PBS, syndromic PBS, and PBS-plus groups. This standardised system will facilitate genotype-phenotype correlations and future prospective multicentre studies assessing medical and surgical treatment outcomes.
