Prostate cancer patients face financial toxicity: Who is affected and how do they cope?


New insights into financial impact on patients with advanced prostate cancer in The Journal of Urology®

July 7, 2023 – Fifty percent of patients with metastatic prostate cancer experience some level of financial hardship due to their treatment, according to a study in the August issue of The Journal of Urology®, an Official Journal of the American Urological Association (AUA). The journal is published in the Lippincott portfolio by Wolters Kluwer.

"Our findings help in understanding the rates of and risk factors for financial toxicity among patients with advanced prostate cancer, along with the coping mechanisms, including the impact on personal spending, experienced by those reporting higher levels of financial toxicity," comments senior author Stephen A. Boorjian, MD, of Mayo Clinic, Rochester, Minn.

"Our most significant finding may be that patients experience financial toxicity despite their ability to remain compliant with treatment," says lead author Daniel D. Joyce, MD. "Simply asking patients whether they are following their suggested treatments is not sufficient to screen for financial toxicity."

New data on financial toxicity rates, risk factors, and coping strategies

The researchers administered a validated questionnaire concerning financial toxicity to all patients seen at their advanced prostate cancer clinic over a three-month period. Financial toxicity – which has been defined as "the harm to patients that results from treatment costs" – has become recognized as important patient-centered outcome. Previous reports suggest that up to half of cancer survivors are affected by financial toxicity, which has been linked to increased rates of adverse treatment outcomes.

Drs. Joyce and Boorjian and colleagues assessed the rate of financial toxicity and the related patient characteristics and coping strategies among patients being treated for metastatic prostate cancer. The analysis included responses from 281 patients, median age 69 years.

Based on the study questionnaire, 79 patients were classified as having high financial toxicity. Overall, 54% of patients said they experienced at least some level of financial hardship related to their cancer treatment. The impact was "more profound" among patients with high financial toxicity, with 89% percent reporting financial hardship.

Patients may make 'profound personal sacrifices' to remain compliant with prostate cancer treatments

Several patient characteristics were associated with higher or lower risks of financial toxicity. Older patients had lower financial toxicity, as each additional year of age was associated with a 25% reduction in risk. For patients who were married (or had a non-married partner), financial toxicity risk was nearly four times lower than for those who were unmarried, widowed, or divorced. Not surprisingly, income was a significant factor: risk of financial toxicity was nine times lower for patients with annual incomes of $100,000, compared to incomes under $20,000.

Patients experiencing high financial toxicity coped in varied ways. They were more likely to decrease spending on basic goods and leisure activities, to use their savings to pay for medical care, to delay filling prescriptions, and to borrow money to pay for their care. "Notably, very few patients reported only partially filling medications or stopping medications altogether due to cost," the researchers write.

More than half of patients with high financial toxicity reported difficulty paying bills – and patients in this group were more likely to have delays in starting cancer treatment. Patients with high financial toxicity were also more likely to use financial assistance programs: 32%, compared to 12% of those with low financial toxicity. "Patients are often unable to meet the high treatment initiation costs without some type of financial assistance program or subsidy," the researchers write.

Dr. Joyce comments: "Some patients may be making profound personal sacrifices in order remain adherent with their prostate cancer treatment, which may have a significant impact on the quality of life that we hope to prolong with these treatments. Conversations about these issues are even more crucial given the observed improvement in financial toxicity among patients in our study who were able to access financial assistance programs."

The researchers highlight the need to identify factors that may mitigate the financial impact of treatments for metastatic prostate cancer. They conclude: "Such data are crucial to understand how to include financial toxicity in shared decision-making and to guide future interventions designed to reduce financial toxicity in this population."

The research findings of Dr. Tao Chunhui, a senior researcher from the Second Institute of Oceanography, Ministry of Natural Resources, were published in Science China: Earth Sciences. Over a decade, Dr. Tao's research team conducted investigations into the distribution patterns and formation mechanisms of hydrothermal activities and associated polymetallic sulfides in the Southwest Indian Ridge (SWIR). They discovered a diverse range of hydrothermal activities with higher frequency and the potential for forming large-scale sulfide mineral deposits than what expected by previous theoretical model. The team also established a sulfide metallogenic model controlled by local enhanced heat supply and deep faults (eHeat-dFault model).

Submarine polymetallic sulfides have significant economic value and are primarily formed through hydrothermal circulation. The two key elements of hydrothermal circulation are the driving heat source and fluid circulation pathways. Through analysis of submarine seismic data, it was found that the driving heat source of the hydrothermal system in the SWIR exhibits local enhanced characteristics, and the depth of the heat source and circulation conduit structures are deeper compared to similar hydrothermal systems in other ridges. These characteristics are mainly manifested in deep magma chambers in the strong magmatic segment, deep detachment faults in the weak magmatic segment, and flip-flop detachment faults in the amagmatic segment. It is commonly believed that the spreading rate controls heat source, magma supply, and tectonic processes. However, this study suggests that the type of hydrothermal circulation system, circulation depth, frequency of hydrothermal activity along the axis, and the scale of sulfide mineralization may be the result of a balance between magma supply and tectonic activity.

For the ultraslow spreading SWIR, local enhanced heat supply and deep fault structures are more direct controlling factors for hydrothermal circulation and sulfide mineralization. The eHeat-dFault sulfide metallogenic model is expected to provide guidance for the exploration and mineralization research of polymetallic sulfides on the ultraslow spreading SWIR.

Why do we find so much amber in Cretaceous rocks?

What would a traveler from the future think if one day s/he could analyze the rocks that are currently forming on the planet? Surely, this person would find quite a few plastic fragments and wonder why this material was so abundant in rocks of a certain age on Earth. This is the same question that geologists and palaeontologists have asked themselves after many years of studying another material: amber, the fossilized resin from the Cretaceous that helps us reconstruct what the forests inhabited by dinosaurs were like.

We know the reason for the abundance of so many plastics in today's ecosystems, "but we can only estimate the natural causes that would explain the production of large quantities of resin in the Cretaceous," says Xavier Delclòs, professor at the Faculty of Earth Sciences of the University of Barcelona and first author of an article published in the journal Earth-Science Reviews that addresses this enigmas of modern palaeontology.

"The stories of plastic and fossil resins are very different, but they have one thing in common: the curiosity involved in observing that some new and relevant phenomenon arose at some point in Earth's history and was recorded in rocks", says Delclòs, member of the Department of Earth and Ocean Dynamics and the Biodiversity Research Institute (IRBio) of the UB.

"Amber, and in particular its abundance, would be of little interest were it not for the fact that it contains in its interior many organisms that inhabited the forests of the past, which have been perfectly preserved as fossils and which today allow us to know the forests of the Cretaceous with a detail that seems unreal sometimes" says Enrique Peñalver, a member of the Geological and Mining Institute of Spain, a national centre of the Spanish National Research Council (CN IGME-CSIC) and also co-author of the study.

How were the large amber deposits formed?

The Cretaceous, a period extending from 145.5 to 66 million years ago, represents a time of rapid evolutionary change and diversification of organisms. Today, the dominant conditions that in the Cretaceous allowed the mass formation of abundant resin deposits all over the planet are not present, nor is it known why there was, at the time of the dinosaurs, such an extremely abundant production of resin.

"For about 54 million years, and for the first time in Earth's history, there was a mass production of resin by plants, and we still don't know why", Delclòs and Peñalver point out. "Production quantities that could have formed fossil resin deposits of what we know today as amber had never been reached. From the Barremian to the Campanian, and thanks to the conditions existing on the planet, certain groups of conifers were able to originate large deposits of fossil resin that open a real window to the ecosystems of the past and today provide very important palaeobiological information. We have called this time span the Cretaceous Resinous Interval (CREI)".

The formation of large amber deposits requires the existence of trees with the ability to produce a lot of resin. During the Cretaceous, only gymnosperms —e.g., conifers— which are evolutionarily older than flowering plants, could produce resin. Moreover, the resin had to be trapped in a sedimentary environment without oxygen to preserve it for millions of years. But what environmental or biological factors could have conditioned such resin production in the Cretaceous?

"Our study shows that, during the Cretaceous, coniferous forests were widely distributed across the planet. These amber deposits formed during the CREI shared these characteristics: high resin production exclusively by conifers; the presence of fusain, a material derived from plant material burnt by forest fires; fossils preserved in amber that correspond to similar fauna and flora among different deposits; and resin accumulation in transitional sedimentary environments under subtropical and temperate paleoclimates that coincide with the onset of sea-level rise stages.

The study also indicates that the mass production of resin was not continuous during the CREI nor was it equal everywhere: there were times of higher and lower production. In the study, carried out by a large multidisciplinary group of experts, the participation of Ricardo Pérez de la Fuente, from the Oxford University Museum (United Kingdom), is particularly noteworthy.

An open window to the vanished world of the Cretaceous

Pieces of amber recovered by palaeontologists in different sites around the world provide new insights into the Cretaceous. This period saw the emergence of large terrestrial ecosystems dominated by angiosperms — flowering plants — and many of the evolutionary lines of present-day organisms. The distribution of continents and ocean currents was altered, the climate was warmer and more humid than today's, and sea levels rose more than 200 meters above today's coastlines.

"In the atmosphere there were high levels of carbon dioxide (CO2) due to intense volcanism, but also of oxygen (O2) due to the great extension of forests to latitudes now covered by ice, a feature that also enhances large-scale fires", Delclòs and Peñalver note.

This is the global landscape and environment that dominated the Earth during much of the Cretaceous. The environmental factors conditioned the life and evolution of the organisms that existed on the planet, especially the terrestrial ones, from the smallest to the great dinosaurs, and the relationships between the different species.

In this scenario, the CREI emerges as a global phenomenon, with amber outcrops distributed everywhere during the Cretaceous, and concentrated especially in Laurasia and the northern margin of Gondwana. Environmental factors may have affected on a global scale, while biological factors — interaction between plants and arthropods, etc. — may have acted on a regional scale.

"CREI represents a great window to a vanished world, at the beginnings of modern ecosystems dominated by flowering plants, where dinosaurs lived, and where the lineages of the first birds and mammals evolved. Studying this period allows us to obtain many data of maximum scientific interest on phylogenetic relationships, extinct organisms, the beginning of behaviours that we can recognize today in many groups, intra- and interspecific relationships of extinct organisms (parasitism, pollination, parental care, swarming, forestry, reproduction, etc.) of the inhabitants of a terrestrial environment —the forest— that are not usually fossilized", the experts conclude.

  

This research aims to unravel evolution mysteries about how the forest ecosystems were 110 million years ago.

Madagascar hippos were forest dwellers


Research demonstrates the important role woodlands have played on the island

DWARF HIPPO

Extinct dwarf hippos that once roamed Madagascar lived in forests rather than open grasslands preferred by common hippos on mainland Africa, researchers at the University of Cincinnati discovered.

The findings suggest grasslands that now cover much of the enormous island off the eastern coast of southern Africa were a relatively recent change facilitated by people rather than a natural habitat sustained in part by these famously large vegetarians.

The study was published in the journal Plants, People, Planet.

When Madagascar broke away from Africa’s mainland 150 million years ago, its plants and animals evolved in geographic isolation in the Indian Ocean. Madagascar had no elephants, giraffes, rhinos or other big mammals like those found on the mainland today.

But it did have hippos.

About the size of a cow, the dwarf or Malagasy hippo was far smaller than its four-ton cousin, the common hippopotamus. Even so, the Malagasy hippopotamus was among the largest land animals on the island along with Nile crocodiles and the flightless and enormous elephant bird.

These hippos likely resembled today’s secretive and endangered pygmy hippos found in the forests and swamps of West Africa’s Liberia and Guinea, said Brooke Crowley, a UC professor of geosciences and anthropology and lead author of the study.

“Ecologically, we think the Malagasy dwarf hippos were pretty close to the pygmy hippos that live in forests in West Africa,” Crowley said.

Crowley and her research colleagues conducted an isotopic analysis of stable carbon and nitrogen found in the bones of extinct Malagasy dwarf hippos that roamed the island more than 1,000 years ago. These isotopes, found in the bones of animals, leave behind a fingerprint of the foods they ate. And this provides clues about their preferred habitats.

Researchers took samples from the bones of dwarf hippos at museums along with those the team collected on the island. They found that dwarf hippos did not regularly graze on grass in dry, open habitats, even in regions dominated by grassland today. Instead, they preferred plants found in the wetter, more forested landscapes. This suggests forest was more abundant before people began changing the landscape to grow cultivated plants, graze domesticated cows and goats and obtain firewood and building materials.

Common hippos on the mainland love grass. Their name derives from the Greek words for “river horse.” Each night they leave the safety of rivers and waterholes to find fresh pasture, cropping grass like a horse, before returning in the morning.

But the researchers’ analysis found that grass represented only a small part of the diet of Malagasy dwarf hippos. Instead, they behaved more like browsers, feeding on sedges and leaves. As a result, hippos likely had little influence on maintaining or expanding grasslands on the island.

“For years we’ve seen evidence that these animals were not grazers,” said Laurie Godfrey, a study co-author and professor emerita at the University of Massachusetts Amherst.

Godfrey said there is evidence to suggest that people caused the extinction of hippos on the island when they created permanent communities and moved from hunting and gathering to raising domestic animals and crops. She calls her idea the “Subsistence Shift Hypothesis,” which she said is an elaboration on a similar idea first proposed by noted archaeologist Robert Dewar.

“There is pretty compelling convergent evidence showing that many of the extinct animals disappeared in a short window of time coinciding with the transition of people from hunting and gathering to pastoralism,” UC’s Crowley said.

Crowley thinks restoring native forests is key to helping conserve wildlife on the island. Based on their study, expansive grasslands were not a critical habitat, at least for the island’s hippos.

“Some colleagues argue that grasslands are ancient and that we need to protect and manage them like we do forest,” Crowley said. “I would argue that forests are far more important. We are not contending that grasses did not exist in the past, but pointing out that there is no evidence for large grasslands devoid of trees prior to about 1,000 years ago.”

It’s a point the researchers make in the study as well.

“It is clear that Madagascar faces a biodiversity crisis much greater than that which it has already endured. Preventing this crisis will demand new conservation actions,” the study concluded.

The study was supported by grants from the National Science Foundation, the African Regional Research Program Fulbright and the National Geographic Society.
