Understanding "Patient refuses" among 90+ year old patients with cancer or presumed cancer.

OBJECTIVES: Patients who are 90+ years of age are a growing - but understudied - group at risk for cancer. Because many of these patients are undertreated (with no tissue/cytologic diagnosis), we sought to better understand how such decisions are arrived upon. METHODS: This study focused on patients between 2007 and 2017. None had received cancer therapy. Medical records were reviewed for quotations relevant to decision-making and analyzed qualitatively. RESULTS: Ninety-four patients (median age 93 years) with a cancer diagnosis/presumed diagnosis were identified; most were women (82%) with an average of six co-morbidities (dementia occurred in approximately one-third). The primary qualitative theme was a keen appreciation on the part of all stakeholders of the gravity of the decision to forgo a cancer work-up/therapy, with four subthemes: 1) substantial, detailed medical information about the patient's medical condition ("600 mL of yellow, hazy fluid with an LDH [lactate dehydrogenase] level greater than 450 …"); 2) complex discussions about the risks and benefits of no biopsy and/or no cancer treatment ("[the patient] would not prefer to have the quality of any remaining time ruined with salvage chemo and radiation"); 3) the inclusion of multiple individuals in decision-making ("I had a lengthy discussion with the patient and her daughter;" "I spoke by phone with one of my pathology colleagues"); and 4) patient-voiced decision-making ("I want to die."). CONCLUSION: Healthcare providers appear to understand the seriousness of no cancer-directed therapy and no work-up in patients 90 years of age and older. Neither ageism nor nihilism was observed.

Specific features of the oldest old from the Longevity Blue Zones in Ikaria and Sardinia.

Human longevity may be found in single individuals as well as in the population as a whole ("population longevity"). Longevity Blue Zones (LBZs), which are areas with an unusually high number of oldest old, have been identified in Sardinia and the Greek island of Ikaria. We compared the lifestyle, health status and some genetic markers of the LBZ populations with those of reference populations from Italy and Greece; the data were extracted from the GEHA database. In the LBZs, the proportion of individuals who never married or were married and still living with their spouse was significantly greater. Nonagenarians males and females with a high self‒perception of optimism and/or a high score for self-rated health were also found in larger proportions in LBZs. Among the variables with lower frequency were the proportion of the widowed, the percentage of subjects who had suffered a stroke and the frequency of Apoε4 and Apoε2 and the TT genotype of FOXO3A gene. Compared to behavioral and health indicators, the impact of genetic factors might be relatively less important in the LBZs. Nevertheless, further research is needed to identify potential epigenetic traits that might play a predominant role due to the interaction between genetics and the human and physical environments.
