Clinical and demographic predictors of survival for fibrolamellar carcinoma patients-A patient community, registry-based study.

Fibrolamellar hepatocellular carcinoma (FLC) is a rare primary liver cancer that affects primarily adolescents and young adults. It is associated with a poor overall prognosis. There is a need to better define risk factors, but small sample size has limited such studies. An FLC patient registry now provides data sufficient for statistically robust inferences. We leveraged a unique patient community-based FLC registry to analyze the prognostic impact of demographic and clinical characteristics evident at diagnosis. Variables were analyzed using Cox proportional hazards regression to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). In multivariable models of 149 patients (88 females and 61 males), female gender was associated with statistically significant improved survival with HR of 0.52 (95% CI 0.29-0.93). Factors evident at diagnosis that are associated with worse survival included the presence of 10 or more tumors within the liver (HR 7.1; 95% CI 2.4-21.04), and metastases at diagnosis (HR 2.17; 95% CI 1.19-3.94). Positive lymph nodes at diagnosis, despite being found significantly associated with worse survival in a univariate analysis, did not remain significant when adjusted for covariates in a multivariable analysis. We found no statistically significant effect of age at diagnosis nor tumor size at diagnosis on survival. Female gender may confer a favorable prognosis in FLC. Established high-risk prognostic factors that we confirmed in this Registry included the diagnostic presence of numerous intrahepatic tumors, and metastases. This is the first study derived from a FLC patient community-based registry, and highlights how registries of rare tumors can empower patients to meaningfully advance clinical and scientific discoveries.

Targeting BCL-XL in fibrolamellar hepatocellular carcinoma.

Fibrolamellar hepatocellular carcinoma (FLC) is a rare and often lethal liver cancer with no proven effective systemic therapy. Inhibition of the antiapoptotic protein BCL-XL was found to synergize with a variety of systemic therapies in vitro using cells dissociated from patient-derived xenografts (PDX) of FLC or cells dissociated directly from surgical patient resections. As BCL-XL is physiologically expressed in platelets, prior efforts to leverage this vulnerability in other cancers have been hampered by severe thrombocytopenia. To overcome this toxicity, we treated FLC models with DT2216, a proteolysis targeting chimera (PROTAC) that directs BCL-XL for degradation via the von Hippel-Lindau (VHL) E3 ligase, which is minimally expressed in platelets. The combination of irinotecan and DT2216 in vitro on cells directly acquired from patients or in vivo using several xenografts derived from patients with FLC demonstrated remarkable synergy and at clinically achievable doses not associated with significant thrombocytopenia.

The Advance Care Planning Readiness Scale: Development and Validation of a Measure of Willingness to Discuss and Acceptance of End-of-Life Care in Gynecologic Cancer Patients.

OBJECTIVE: The objective of this article was to develop and validate a scale that assesses the readiness of gynecologic oncology patients to engage in advance care planning. METHODS: The Advance Care Planning Readiness Scale (ACPRS) was validated across 3 independent samples of gynecologic oncology patients. In step I, patients underwent cognitive interviewing to determine if the scale items were comprehensible and applicable to patients. Based on this, modifications to the scale (addition, removal, and merger of items) were completed. In step II, the revised scale was administered to a new sample of patients to assess scale reliability and validity. An exploratory factor analysis determined if the scale loaded onto unique factors. In step III, the revised scale was administered to a third sample of patients, and a confirmatory factor analysis was conducted to test the factor structure proposed in step II. Associations between ACPRS score and completion of advance directives were evaluated. RESULTS: Based on patients' responses, the original ACPRS used in step I was modified to the ACPRS used in step II. The final 8-item ACPRS is a valid, reliable (Cronbach α = 0.81) scale and has 2 primary factors. Women with medical power of attorney documents and living wills had higher ACPRS total scores than those who did not have these advance directives (P = 0.0030). Women with do-not-resuscitate (DNR) orders had higher ACPRS total scores than women without DNRs (P = 0.0176). CONCLUSIONS: The ACPRS is a valid and reliable 8-item scale that assesses the readiness of gynecologic oncology patients to discuss advance care planning issues.

Room for improvement: An examination of advance care planning documentation among gynecologic oncology patients.

OBJECTIVES: The goals of this study were: (1) to evaluate patients' knowledge regarding advance directives and completion rates of advance directives among gynecologic oncology patients and (2) to examine the association between death anxiety, disease symptom burden, and patient initiation of advance directives. METHODS: 110 gynecologic cancer patients were surveyed regarding their knowledge and completion of advance directives. Patients also completed the MD Anderson Symptom Inventory (MDASI) scale and Templer's Death Anxiety Scale (DAS). Descriptive statistics were utilized to examine characteristics of the sample. Fisher's exact tests and 2-sample t-tests were utilized to examine associations between key variables. RESULTS: Most patients were white (76.4%) and had ovarian (46.4%) or uterine cancer (34.6%). Nearly half (47.0%) had recurrent disease. The majority of patients had heard about advance directives (75%). Only 49% had completed a living will or medical power of attorney. Older patients and those with a higher level of education were more likely to have completed an advance directive (p<0.01). Higher MDASI Interference Score (higher symptom burden) was associated with patients being less likely to have a living will or medical power of attorney (p=0.003). Higher DAS score (increased death anxiety) was associated with patients being less likely to have completed a living will or medical power of attorney (p=0.03). CONCLUSION: Most patients were familiar with advance directives, but less than half had created these documents. Young age, lower level of education, disease-related interference with daily activities, and a higher level of death anxiety were associated with decreased rates of advance directive completion, indicating these may be barriers to advance care planning documentation. Young patients, less educated patients, patients with increased disease symptom burden, and patients with increased death anxiety should be targeted for advance care planning discussions as they may be less likely to engage in advance care planning.
