1:34
everyone, welcome back to another episode of Behind the
1:36
Knife with the Palliative Care team from University of
1:38
Washington. I'm Virginia
1:40
Wang, joined again by Lindsay Dickerson, Ali
1:43
Haruta, and Dr. Katie O'Connell. Today,
1:45
as part of our first journal review, we
1:47
have two exciting randomized controlled trials to discuss.
1:51
Dr. O'Connell, can you share some context for why we chose to
1:53
discuss these two trials? Of
1:55
course. There is a body
1:57
of work in the medical oncology
1:59
literature that has been done. included
2:01
multiple randomized control trials demonstrating benefits
2:04
of early palliative care for patients
2:06
with lung, GI, and
2:08
hematologic malignancies. Lindsay,
2:10
can you tell us about the kind of benefits
2:12
they have seen? Absolutely.
2:15
The list is long, and we know this both
2:17
from the data as well as our own clinical
2:19
experiences. Benefits include improved
2:21
patient quality of life, emotional well-being,
2:23
its symptom management, decreased
2:25
anxiety and helplessness, enhanced
2:28
goal-cucordic care, decreased
2:30
caregiver burden and distress, reduced
2:33
costs and decreased utilization of non-beneficial medical
2:35
care at the end of life, and
2:37
even prolonged survival in some populations. Similar
2:41
literature previously did not exist for
2:43
the surgical oncology patient population, which
2:46
makes these studies unique and important. The
2:48
study population in both these
2:50
studies are patients undergoing non-palliative
2:53
abdominal surgery for cancer. Yeah,
2:55
and I think a surgeon was more especially interested
2:57
in the sort of population, so looking
3:00
at palliative care in this space is
3:02
really interesting to us. The
3:04
first trial we'll be discussing was described
3:06
in the manuscript titled, Effects of Specialist
3:08
Palliative Care for Patients Undergoing Major Abdominal
3:11
Surgery for Cancer. This was
3:13
published in JAMS Survey this past May
3:15
by author Dr. Chanal Antin. The
3:18
primary objective of this single-center RCT
3:20
conducted at Vanderbilt was to determine
3:22
the effect of a specialist palliative
3:24
care intervention on patients undergoing abdominal
3:26
cancer operations for cure or durable
3:28
control of cancer. Lindsay,
3:31
tell us how the trial was designed. Sure,
3:33
Allie, and fair warning, I'm going to get
3:35
into a few details here. Between
3:39
2018 to 2021, 235 patients were
3:41
enrolled and randomized to either
3:43
the specialty palliative care intervention
3:45
or usual care group in
3:47
a one-to-run ratio. Both 217
3:50
of these 235 patients ultimately
3:53
included in the primary analysis. In
3:55
addition to usual surgical care, the
3:57
specialist palliative care intervention consisted of
4:00
primary elements. One, a
4:02
pre-op consultation with a palliative care physician
4:04
or NP in clinic or by phone.
4:07
Two, inpatient specialist palliative care
4:09
provider visits at least twice
4:11
weekly during the post-op hospital
4:13
stay. Three, follow-up clinic
4:15
visits or phone calls with the palliative
4:18
care specialist between hospital discharge and post-op
4:20
day 90. And finally,
4:22
an inpatient specialist palliative care visit
4:25
anytime the patient was readmitted to the hospital. Eligible
4:28
surgeries included your standard list of the
4:31
abdominal cancer operations including
4:33
gastrectomy, hepatitis me, pancreasectomy,
4:36
colectomy or proctectomy meeting specific
4:38
criteria given the relatively lower
4:40
associated and morbidity with these
4:42
surgeries, radical cystectomy pelvic
4:45
degeneration, and sider adaptive surgery
4:47
with or without. Oh
4:49
that was a lot. Virginia, can you briefly
4:52
tell us about the study population? Sure.
4:54
So the main takeaway is that this
4:57
trial focused on patients with what were
4:59
deemed to be resectable abdominal and pelvic
5:01
malignancies. There are a couple of additional
5:03
details to mention. So the most
5:06
common malignancies were bladder, colorectal, and
5:08
pancreatic cancer. About 60% of the patients
5:10
in the study had stage 3 or
5:12
4 disease and about 60% of the patients
5:14
received neo-adjuvant therapy.
5:17
One thing of note is that the vast
5:19
majority of all the study participants over 90%
5:22
self-identified as non-Hispanic white. Although
5:25
the study participants appear to have been distributed
5:27
along a range of incomes and to a
5:30
lesser extent a range of educational levels, minority
5:33
patients are severely underrepresented
5:35
in the study population. Thank
5:37
you for calling our attention to that Virginia. We'll keep
5:39
this in mind as we examine the outcomes of the
5:41
study and talk about it more in a bit. So
5:44
let's get into the outcomes. The
5:46
primary outcome was physical and functional
5:49
quality of life at post-epdainity which
5:51
was measured by what's called the
5:53
FACT-G or functional assessment of
5:56
cancer therapy general for G trial
5:58
alchem index. Gina, do you
6:00
remember the four quality of life domains
6:03
the FACT-G assesses? I do. They
6:05
are physical well-being, emotional well-being,
6:07
social or family well-being, and
6:10
maybe the easiest to forget, but one of
6:12
the most vitally important to patients, functional
6:15
well-being. That's right.
6:18
And the secondary outcomes that the study
6:20
was powered to assess included 90-day overall
6:22
quality of life for the FACT-G total
6:24
score versus the primary outcome which focused
6:26
on just the physical and functional quality
6:28
of life domains. Days
6:31
alive at home until post-op day 90, which
6:33
means not admitted to a hospital or seen
6:35
in the emergency department, and overall
6:37
survival at one year. Data
6:39
was analyzed using an intention-to-treat approach.
6:42
Great. Thanks for summarizing all that for me. So
6:45
let's talk about the results. Lindsay, what's
6:47
the one-liner decoy? Well,
6:50
in a few words, there was no
6:52
difference between groups in the primary or
6:54
secondary outcomes. So, specialist
6:57
palliative care in the perioperative
6:59
period for patients who underwent
7:01
non-palliative surgery for abdominal cancer
7:03
did not improve quality of life or
7:05
survival. But I think there are
7:07
more nuances to discuss, which is why we're all here.
7:10
Yeah, true. So, to
7:12
reiterate, there were no statistically significant
7:15
differences between the usual care and
7:17
the specialty palliative care intervention group
7:19
with regard to physical and functional quality of life,
7:22
overall quality of life. Days
7:24
alive at home until post-op day 90,
7:26
and overall survival at one year. In
7:29
the results, the authors also included
7:31
estimates of the Minimal Clinically Important
7:34
Differences, or MCID, from the literature. Dr.
7:36
Kahl, I wasn't super familiar with this term until
7:38
I read more about it. Can you share about
7:41
how I was applicable to this trial? Sure,
7:43
thanks for bringing me back in. The
7:46
MCID is a standard for determining
7:48
the effectiveness of an intervention and
7:50
measures essentially the smallest improvement that
7:53
would be worthwhile or meaningful to
7:55
a patient. This is
7:57
an important concept in this trial because not only
7:59
were. There no statistically significant
8:01
differences between groups. But.
8:03
There were also know clinically
8:06
meaningful differences. However,
8:08
The authors astutely pointed out that
8:10
the median baseline sacked G scores
8:12
for all patients in this study.
8:15
Before. The intervention was higher
8:17
than what is reported for
8:19
the gen U S population. So.
8:23
This. Specific population of surgical
8:25
patients. May. Have started off
8:27
with a lower palliative care
8:29
need compared to other oncology
8:31
or surgical patients. In
8:34
this context, it may not be surprising
8:36
that the Steady Dinner and cynically and
8:38
for differences and ninety days as measured
8:40
by any and see Id. We.
8:43
Need a speak? Well. I
8:45
think these results make sense and are not
8:47
necessarily contradictory to what we know about the
8:49
benefits of crowded of carry intervention. It
8:52
stands to reason that in order for
8:54
a patient to be offered a non
8:56
positive operation, they must have a height
8:58
of baseline of functional status. That.
9:01
The surgeon believes they can tolerate a
9:03
major abdominal operation with outlasting negative impact
9:05
on their quality of life. And functional
9:07
status. Assuming appropriate fusion selection
9:10
for surgery, this inherently biases or
9:12
study population toward patients with better
9:14
functional status and quality of life.
9:16
Compared to a beast, the average
9:18
oncology patient is not the general
9:20
population as the study suggested. Allium
9:22
Lindsay What other factors do you think? Contributed.
9:26
Yes, This might be standing us
9:28
somewhere on his arm and here, but
9:30
the patients in this study had less
9:32
advanced cancer. Overall, the Nas included in
9:34
other palliative care intervention studies. They
9:37
are also relatively young, with a median age
9:39
of sixty five. Soon. And measles
9:41
after under their functional sadness in. Both.
9:44
That are of the time. The surgery he
9:46
entered minded east coast.given a lower likelihood of
9:48
rapid cancer progression are visible, that line. I.
9:51
Agree Alley I would also add that A
9:53
Seat Hope plays a critically important role here,
9:56
and it's something as thought a lot about
9:58
in general because. In. The gone
10:00
college he like and palliative care. There's
10:03
this balance and also harmony between providing
10:05
whole thing and being realistic. Yeah.
10:08
If he were a lot more familiar with this
10:10
balance in the medical oncology population, for example, It's.
10:13
Important to be honest and realistic
10:15
when disclosing serious news like a poor
10:17
prognosis. Which. Can significantly decreased and
10:19
a mood and quality of life of patients.
10:22
But. Then you also want to provide a hope
10:24
that we have options to treat them as
10:26
a whole person, work and underhanded man. Even
10:29
though he can't share their cancer, we can
10:31
start helping. Their remaining time worked wilds of
10:33
them. That's. Absolutely right.
10:35
And I think the situation here is
10:37
different from what. You. Were just
10:39
talking about and medical oncology. These.
10:42
Patients in the surgical oncology world
10:44
are going into surgery with hope
10:46
for what they've been. Told
10:48
is absurd Ever disease control and surgery.
10:50
So once they've recovered from the operation
10:52
in the short term. Their. Physical
10:54
a social function on especially
10:56
emotional. Quality. Of Love and
10:58
Well Being is unsurprisingly similar to what
11:00
it was predominantly. Of personally
11:02
even seen this and patients who
11:04
returned to clinic after a successful
11:06
on logic surgery. I.
11:09
Think you're right. There is something about
11:11
that idea of sure that brings this
11:13
hopes. It's hard to quantify. It
11:15
also just wanted to know. That. They're expensive,
11:18
demonstrated in a medical oncology population
11:20
undergoing nonsurgical treatments a period of
11:22
time. Such. As stem cell transplant.
11:25
So. The opportunity for cure is not
11:27
the only factor that may have contributed to
11:29
the lack of effect seen in the third
11:32
oncology population. But. Certainly be
11:34
idea sure is an important. Source
11:36
of hope. So. Essentially, these patients
11:38
may not have had specific palliative your
11:40
needs of the time of intervention. The.
11:42
The doesn't mean that injuries in the topic
11:45
of palliative care or discussing prognosis for example
11:47
early in the course of cancer for these
11:49
patients is he not beneficial. It's
11:51
just a matter of how we measure any expected
11:53
benefit. When. You think Doctor Clough. Well.
11:57
i see that selection of
11:59
measurable primary outcome is really
12:01
key for detecting differences in
12:04
standard care versus palliative intervention
12:07
studies. If
12:09
the author selected quality of communication
12:11
with the medical team or
12:13
advanced directive completion or
12:16
extended the duration of the study to
12:18
capture recurrence of disease, which usually
12:20
doesn't occur within the study period of
12:23
90 days post-op, there
12:25
may have been a detectable difference. One
12:28
last thing before we move on from this study,
12:30
I think it's important to circle back about the
12:33
demographic factors that we mentioned at the beginning of
12:35
our discussion. As the authors of this
12:37
paper are very well aware, 90 to
12:39
95% of the patients recruited for
12:41
this study self-identified as non-Hispanic white.
12:43
So racial and ethnic minority populations
12:46
are vastly underrepresented here. The
12:48
authors also noted that patients with higher education
12:50
and the ability to travel for care, given
12:53
that this study was conducted at a
12:55
tertiary referral center, were overrepresented in the
12:57
study population as well. Particularly
12:59
since minoritized patients consistently have
13:01
worse outcomes compared with non-Hispanic
13:03
white patients in so
13:05
many different areas of health care,
13:07
including oncology, more outreach is warranted
13:10
to engage underrepresented minority patients and
13:12
address these disparities. This

that this is novel to most

population also a self identified as

16:02
patients were somewhat better represented in this
16:04
multi-center study. A majority of
16:06
all of these patients, around 70% in
16:08
the control arm and around 60% in the
16:11
intervention arm, had a college degree
16:13
or higher. This study also recruited a slightly
16:15
more even distribution of men and women. Lindsay,
16:17
what else should we know about the study design? Always
16:20
making me go into the details of the
16:22
study design. So in
16:25
addition to usual surgical care, including
16:27
free op and post-op visits, patients
16:29
assigned to the intervention group met
16:31
either in person or via phone with
16:33
a member of an interprofessional palliative care
16:35
specialist team prior to surgery, one
16:38
week after surgery, and one, two, and three
16:40
months after surgery, with additional visits
16:42
scheduled at the discretion of the patient
16:44
surgical team or palliative care team. These
16:47
specialists were either hospice
16:49
and palliative medicine-boarded MDs,
16:52
ARNPs, social workers,
16:54
pharmacists, or chaplains trained in
16:56
palliative care with additional specific
16:59
training about GM emergencies. The
17:01
visits most often involved rapport building,
17:03
symptom management, illness education, and coping
17:06
with serious illness. Virginia,
17:08
what was a key difference that you noticed
17:10
in the usual care group for this study?
17:13
Well, this study was designed so that patients
17:15
in the usual care group could
17:17
actually receive a palliative care consultation if
17:19
the surgical team requested it, and
17:22
the surgical teams were encouraged to
17:24
follow NCCN recommended triggers to
17:27
involve specialty palliative care consultation. All
17:30
right, so what about the study outcomes? So
17:33
the study utilized several scales to assess
17:35
their primary outcomes. They're listed
17:37
in more detail as shown out, so I'm not
17:39
going to go into every single one, but basically
17:41
they looked at health-related physical and emotional quality of
17:43
life and mood symptoms. They then
17:45
calculated a summary score looking at several
17:48
different domains. Lindsay, can you tell us what
17:50
those are? Yeah, it might
17:52
be hard to remember all these, but luckily I have them
17:54
written here. Cognition, depression,
17:56
fatigue, pains, physical,
17:59
sleep, and social. That's
18:01
right. So the primary study
18:03
outcome was difference in patient-reported health-related
18:06
quality of light at three months
18:08
after surgery. Exploratory subgroup
18:10
analyses were planned as related to
18:12
race, ethnicity, and study sites. And
18:15
now the moment we've been waiting for, Virginia has taken
18:17
away with the result. Well, as in
18:20
the prior study, no statistically
18:22
significant differences were identified between the
18:24
control and intervention groups in any
18:26
of the health-related quality of light metrics. There
18:29
were also no significant differences in mortality
18:31
between the two groups. It
18:34
is interesting to see that 20 of the 177 patients randomized to the
18:38
control arm were actually referred for
18:40
palliative care consultations during the first three
18:42
months post-op, and five of the
18:44
patients were referred for hospice care. Notably,
18:47
one center accounted for the vast
18:49
majority of these crossover referrals, and
18:51
that is the same center that had the highest enrollment
18:54
in the study. This demonstrates some
18:56
variable practice of routine integration of
18:58
palliative care into surgical treatment nationwide.
19:01
Lindsey, do you want to talk a little bit about what
19:03
your takeaways were from this? Sure. I do
19:05
think that's a keen point in the difference in this
19:08
control population, that the
19:10
surgeons have the opportunity to refer patients
19:13
for palliative care treatment, and that 20
19:15
of the patients randomized to the control
19:17
group were referred. So
19:19
overall, like the first trial we
19:21
discussed, this trial also focused on
19:23
patients undergoing operations with care to
19:25
attend. The authors of this
19:27
study also noted that as
19:30
we have more nuanced discussions about the
19:32
best timing for palliative care interventions for
19:34
surgical oncology patients, the particular juncture
19:37
described in both of these trials
19:39
may be too early in the
19:41
patient's cancer journey to measure the
19:43
benefit of specialty or specialist palliative
19:45
care engagement. And this is like what
19:47
you touched on earlier, Dr. O'Connell. I'm
19:50
curious to hear what additional thoughts you might have.
19:53
Overall, it seems that it may
19:55
be more difficult to demonstrate a
19:57
measurable impact of specialty palliative
19:59
care. engagement at this time point
20:02
for patients with higher baseline quality
20:04
of life and milder
20:06
cancer-related symptoms, even
20:08
if they have a serious diagnosis
20:11
like an upper GI malignancy requiring
20:13
major abdominal surgery. I
20:15
also noticed that 119 eligible patients
20:17
actually declined to participate in this
20:19
study, and the most common reasons
20:22
they gave for declining to participate
20:24
included being too overwhelmed,
20:26
stressed, or generally tired. A
20:28
lot of what palliative care visits could have
20:30
addressed would be those specific feelings,
20:33
so it is possible that we
20:35
missed some patients who could have had
20:37
a measurable benefit because they self-selected out
20:39
of the study. I'm curious
20:41
to know if those patients have actually stopped palliative
20:43
care as part of their treatment. It sounds like
20:45
potentially there would be something that comes down the
20:48
pipeline that triggers it. Another
20:50
thing I just wanted to point out is that
20:52
they found no measurable harm in the intervention group
20:54
for patients or surgeons, and this
20:56
might seem obvious or not super relevant at
20:58
first glance, but conversations in the palliative care
21:00
space are often really difficult. They
21:03
touch on sensitive topics, so it's
21:05
important to see that these discussions didn't
21:07
cause increased distress or actually worsened quality
21:09
of life. This is
21:11
just from my clinical experience, not from
21:13
the data, but often people are really
21:15
reluctant to talk about palliative options in
21:17
addition to disease-directed therapies. They
21:20
think it might be viewed as them giving up or
21:22
causing patients to lose hope. And
21:24
there's this idea of, like, fighting. We always want
21:26
to keep fighting. So you obviously
21:29
have to meet patients where they're at. You can't
21:31
push them to talk about things that they aren't
21:33
ready to think about. But it's really
21:35
important to remember that palliative care can
21:37
and should be delivered in parallel with
21:39
life-sustaining treatment. One doesn't cancel out
21:41
the other. So while there
21:43
weren't measurable benefits to specialty palliative care
21:46
co-management in this study, surgeons
21:48
should still feel empowered to integrate primary palliative
21:50
care into the patient visit. Allocating
21:52
their hopes, their goals, their concerns, building
21:54
rapport so that they can think about
21:56
what treatment recommendations make the most sense
21:59
for each patient. It's really
22:01
hard in my opinion to find the right
22:03
way to measure the value of a lot
22:05
of these palliative care visit components such as
22:08
rapport building, providing space for the patient, or
22:10
just offering support during difficult times. Maybe
22:13
I'm just in my soapbox, but Dr. O'Connell, what else
22:15
would you add? At the
22:17
risk of repeating myself, had the primary
22:19
outcome been measured beyond three months, you
22:22
know, perhaps at like a year when there
22:24
would have been cancer recurrences and when the
22:26
palliative care team utilizes that
22:28
built rapport, that is
22:30
where the differences will be measured. Much,
22:33
much easier said than done in a
22:35
randomized controlled trial. Thank
22:38
you everyone for a really lively discussion
22:40
about these two seminal palliative care randomized
22:42
controlled trials in the surgical-alcoholic patient population.
22:45
While both of these were technically negative studies,
22:48
in that neither of the studies detected
22:50
a statistically significant difference in primary or
22:53
secondary outcomes as related to health-related quality
22:55
of life scores, there are still
22:57
many interesting insights to be gained from these trials
23:00
and more room for further study. We
23:02
would be particularly interested to see more
23:04
research centering minoritized and marginalized patient populations
23:06
and their engagement with palliative care during
23:09
their cancer journeys, of course recognizing
23:11
that there are limitations inherent to
23:13
conducting these types of studies at tertiary
23:16
referral centers. So,
23:18
