Rapid development and use of patient-specific ctDNA biomarkers to avoid a "rash decision" in an ovarian cancer patient.

ABSTRACT: Epithelial ovarian cancer (OvCa) is the most lethal female reproductive tract malignancy. A major clinical hurdle in patient management and treatment is that when using current surveillance technologies 80% of patients will be clinically diagnosed as having had a complete clinical response to primary therapy. In fact, the majority of women nonetheless develop disease recurrence within 18 mo. Thus, without more accurate surveillance protocols, the diagnostic question regarding OvCa recurrence remains framed as "when" rather than "if." With this background, we describe the case of a 61-yr-old female who presented with a 3-mo history of unexplained whole-body rash, which unexpectedly led to a diagnosis of and her treatment for OvCa. The rash resolved immediately following debulking surgery. Nearly 1 yr later, however, the rash reappeared, prompting the prospect of tumor recurrence and requirement for additional chemotherapy. To investigate this possibility, we undertook a genomics-based tumor surveillance approach using a targeted 56-gene NGS panel and biobanked tumor samples to develop personalized ctDNA biomarkers. Although tumor-specific TP53 and PTEN mutations were detectable in all originally collected tumor samples, pelvic washes, and blood samples, they were not detectable in any biosample collected beyond the first month of treatment. No additional chemotherapy was given. The rash spontaneously resolved. Now, 2 yr beyond the patient's original surgery, and in the face of continued negative ctDNA findings, the patient remains with no evidence of disease. As this single case report suggests, we believe for the first time that ctDNA can provide an additional layer of information to avoid overtreatment.

Project description:BackgroundShared decision-making for surgery can increase patient engagement, satisfaction, and clinical outcomes. However, the level of involvement that patients desire at each step of the decision-making process is unknown.MethodsThe authors surveyed patients at an academic hand surgery clinic to examine the preferred role in decision-making using validated questionnaires (i.e., Control Preference Scale, Problem-Solving Decision-Making Scale, and General Self-Efficacy Scale). The Control Preference Scale assesses general treatment preferences, whereas the Problem-Solving Decision-Making Scale distinguishes between problem-solving tasks (e.g., making diagnoses, calculating risks/benefits) and decision-making tasks. Patients' self-beliefs and perceived ability to handle difficult situations were assessed with the General Self-Efficacy Scale. The authors used linear regression models and ordinal logistic regression to examine the relationship between self-efficacy and patients' preferred role in treatment decision-making.ResultsPatients overall preferred an equal share of decision-making responsibility with the surgeon (mean Control Preference Scale score, 3.3 ± 0.7). Specifically, for problem-solving tasks, however, 81 percent of patients wanted to "hand over" the responsibility and 19 percent preferred shared decision-making. In contrast, for decision-making tasks, 54 percent of patients preferred shared decision-making. Each point increase in General Self-Efficacy Scale score correlated with 12 percent greater odds of preferring to retain the responsibility (OR, 1.12; 95 percent CI, 1.05 to 1.21; p = 0.001). However, self-efficacy did not show a significant effect for problem-solving tasks.ConclusionsThe authors found that patients prefer surgeons to provide expert knowledge for problem-solving tasks but desire equal share of responsibility in decision-making tasks. The authors' findings support the current shift away from the paternalistic model of surgical decision-making, and provide an effective strategy to tailor shared decision-making to align care delivery with patient preferences.
