Palliative Surgery and the Role of Surgery for Stage IV Cancer - Ricardo J. Gonzalez, MD Assistant Professor of Surgery University of Colorado
Objectives
• Discuss the classic management of advanced disease
• Define palliation and palliative surgery
• Review literature on palliative surgery and metastectomy

• Make sense of anecdote and logical conjecture by
  employing well-characterized information for specific
  patient groups in difficult situations

“In the field of surgical oncology tumor
  biology is king, patient selection is queen,
  and technical maneuvers are the prince
  and princess who try, but usually fail, to
  usurp the throne.”

                                   Cady Arch Surg 1997

Advanced/Incurable disease
• Classic teaching
  – Chemotherapy is the treatment of choice
  – Radiation only for symptomatic lesions
  – Cure or even long-term progression free
    survival is not likely
Palliative Surgery and the Role of Surgery for Stage IV Cancer - Ricardo J. Gonzalez, MD Assistant Professor of Surgery University of Colorado
Advanced/Incurable disease
• Arguments against surgery
  – Survival is driven by the rate and volume of
    metastatic burden
  – Unhealthy patients that can’t tolerate surgery
     • Risk benefit ratio is heavily weighted toward the
       risks
  – Theoretical risk of “angering the tumor” or
    “letting the air in”
     • Elaboration of VEGF or other angiogenic factors
       from anesthesia, surgical stress, blood transfusion
       and various other unknowns
Palliative Surgery and the Role of Surgery for Stage IV Cancer - Ricardo J. Gonzalez, MD Assistant Professor of Surgery University of Colorado
Advanced/Incurable disease
• Arguments for surgery
  – Improving quality of life and symptom control
  – Debulking gives chemotherapy a fighting chance
  – Alter the metastatic cascade
     • removing the primary tumor
     • removing the metastases
  – Removing the inhibitory peptides/molecules that
    depress the local immune response to the tumor 
    enhancing the anti-tumor immunity to the remaining
    tumor cells
Palliative Surgery and the Role of Surgery for Stage IV Cancer - Ricardo J. Gonzalez, MD Assistant Professor of Surgery University of Colorado
Surgery and metastatic disease
• Must decide and discuss the goals early
• What are the goals?
  1. Palliation – symptoms/QOL
  2. Improve upon progression-free survival
  3. End of life goals met with surgery
  4. Curative intent
Palliative Surgery and the Role of Surgery for Stage IV Cancer - Ricardo J. Gonzalez, MD Assistant Professor of Surgery University of Colorado
Is this really that important?
• Cancer is the 2nd most common cause of death
  (1/3 diagnosed and 1/3 die)

• End of life care consumes 12% of national
  health care expenditure and 27% of Medicare
  expenditures.

• 12.5 % of surgical procedures are for palliative
  reasons

Palliative Surgery and the Role of Surgery for Stage IV Cancer - Ricardo J. Gonzalez, MD Assistant Professor of Surgery University of Colorado
What’s Needed?
•   Miner et al Am J Surg 1999  348 publications
    – primarily focused on morbidity and mortality, while
       only 12% of studies considered pain relief, 2%
       considered cost, and 17% evaluated QOL.
    – Curative surgery is based on robust data and
       evidenced-based decision making; palliative surgery
       is not.
•   What’s needed:
    1. Better define palliative surgery
    2. Study more meaningful end results and establish
       standards for which logical and thoughtful decisions
       can be made

Palliation
• Relieve symptoms for patients beyond cure when non-
  surgical measures are not feasible, not effective, or not
  expedient

• Palliation means patient should be better at the
  completion of the procedure or treatment

“It is axiomatic that one cannot palliatively improve an
    asymptomatic patient using a scalpel.”
     – R. G. Martin, 1982
Palliative Care – Evolution - Early
Quotes from a palliative care doctor
• “We are not team death”
• “We are not a death squad”

Quotes from those who do not understand palliative
 care
•   “Here come the grim reapers”
•   “Oh here they come dressed in black”
•   “They’ll just drug ‘em with morphine”
•   “If he’s not comatose now just give them a shot at him”
The Surgical Treatment of Cancer: A Comparison of
Resource Utilization following Procedures Performed with
Curative and Palliative Intent
 Purpose - evaluate the immediate and short term resource
    utilization needs of patients undergoing surgical
    intervention with curative or palliative intent.
 Methods - 302 pts identified as palliative (58) or curative
    (244) and followed for 6 months
 Findings
 • Avg # of patient encounters no different
    – Patients undergoing surgery for palliative intent require
      equal resources
 • Character of resources is different:
    – palliative patients  admitted for symptom control and had
      fewer hospital free days
    – curative intent  utilized services directed at their continued
      treatment.

Aim: compared hospital vs. hospice based
  costs during last 60 days of life for ovarian
  cancer patients
• Billing records were analyzed for inpatient
  and outpatient costs.

Palliative Care – Evolution - Today
•   Establish the patients’ goals
    and personalize therapy based
    upon those goals
•   Symptom control for long term
    pain management in terminal
    patients
•   Helping the family and the
    patient cope with and accept
    the situation
•   Help achieve fullness of life

•   Reduces end of life health care
    costs by 25-40%

Palliative Care – Evolution - Today
• Have far-reaching effects outside what you see in the
  hospital
• Should be involved earlier and with increasing
  responsibility during the treatment of patients with
  incurable cancers

                         When to involve the Palliative Care Team:
                         1. When your attending gives you the OK
                         2. When the labor of symptom control
                            outstrips the teams resources or
                            understanding
                         3. Difficult social or psychological situation

•   Primary goal is improving symptoms
    caused by advanced malignancy
•   Effectiveness – presence and durability of
    patient-acknowledged symptom resolution
•   Successful:
     1. improvement in QOL
     2. minimal morbidity and mortality
     3. modest resource utilization

• Conclusions
  – In select patients palliation can be expected
  – Durability of symptom control may be limited
    by the development of new symptoms
  – Potential benefit may be limited by poor
    performance, malnutrition, and no prior
    cancer treatment

What about metastatic disease?
Surgery and Metastatic Disease

•    Can we alter the natural history of the disease?
     –   Does removing the primary alter progression-free or
         overall survival?
•    Is there any benefit to Stage IV NED?
•    How do we select patients for surgery and keep
     long term survival as our goal?
     –   Two approaches
         1. The Pragmatic approach
         2. The Academic approach
Patient selection – Pragmatic

1. Is the patient insured?

2. Is the Oncologist a friend of mine or do I want
   him to be a friend of mine?
3. If not insured then is the patient loaded and will I get
   an endowed chair?
4. Any on-going studies for which I need patients?
5. Should I go snowboarding instead of taking this on?
6. Do I need a break from M&M?
7. Is there any patient benefit? (Last consideration)
Patient selection – Academic
1. Do we have a clinical trial in our center?

2. What is this patients performance status?

3. Are there any contraindications based on
   comorbidities?

4. Do I understand the disease progression for this
   particular patients tumor prior to considering surgery?

5. Is there any chance for patient benefit or can I improve
   upon his symptoms?
(ALWAYS AT THE FOREFRONT OF THE ANALYSIS!!)
The Pragmatic
 “After a while you spend so much time trying to
 fend off the Grim Reaper you wonder if you’re
 ever going to win or even why you’ve gotten
 yourself into this mess.”
                         Nathan W. Pearlman on Rounds 2004

The Academic
“In the field of surgical oncology tumor biology is
king, patient selection is queen, and technical
maneuvers are the prince and princess who try, but
usually fail, to usurp the throne.”

Stage IV Melanoma
• Sobering statistics
  – 0.76 – 1.5 mm  25% nodal mets in 3 yrs
  – 1.5 – 4.0 mm  60% nodal mets in 3 yrs and
    15% distant mets in 5yrs
• Site of distant recurrence predicts survival
  – Nodal  20 – 50% at 5 yrs
  – Visceral  5% at 5yrs

Stage IV Melanoma

Three criteria cited as predictive of survival after
   complete metastatic resection – biology is king.
     1. The site of metastasis
        • visceral vs. nonvisceral
        • visceral pulmonary vs. nonpulmonary
     2. The number of metastatic lesions
        • more is worse
     3. The disease-free interval before the
        development of metastases
        • more than a year
                                         Allen PJ ASO 2002
Stage IV Melanoma

•   Patient selection is queen
•   26,204 pts with melanoma
•   1,750 (7%)pts with liver mets
•   34/1750 (2%) explored (med DFS 58 mos
    and 75% solitary mets)
    – 16 aborted and 18 resected
    – Of resected 5 (27%) were NED
    – 0.3% of patients with liver mets!!

                                     Rose DM Arch Surg 2001
Stage IV Melanoma

• Complete resection is the only technical
  maneuver that potentially alters the natural
  history of the disease – the princess.

• Prior to proceeding forward with this approach
  you need a complete staging workup
  – H&P, labs (LDH), PET/CT scan
  – brain MRI and bone scan (symptomatic patients)
Stage IV melanoma –skin/soft tissue
• Most common (59%) initial site of distant recurrence is
  skin, subcutaneous tissue and regional nodes.

• Complete resection
   – Median survival as high as 50 months
   – 5 year overall survival of 38%

• DFI has highest predictive value with best prognosis if
  >18 months after primary resection.
• Surgical palliation is strongly encouraged because it is
  easily accomplished with minimal morbidity.

Surgery and Stage IV Disease: should
      we remove the primary?
• Yes if
   – The lesion is symptomatic or will soon become
     symptomatic
   – The disease classically responds to chemotherapy
   – Patients can live a long time with mets
   – Removing the lesion can be achieved with low
     morbidity

• No if all of the above do not apply

Do tumor-bearing patients have decreased
                tumor immunity?
• Multiple hypotheses
      – immune tolerance of the host to tumor antigens1
      – genetic changes in tumor cells that render the tumor cells
        “immune” to the host’s immune system2-4
      – “ignorance”or lack of activation to tumor antigens5
      – dysfunction of potentially tumor-reactive lymphocytes
        rendering them unresponsive to antigen6
      – immune suppression mediated by tumor cell secretion of
        inhibitor factors and/or activation of systemically
        immunosuppressive cells7,8

Summary
Goals should be patient-directed and discussed early

Palliative surgery should be considered after careful patient
    selection
•   Success is determined by:
    1. Symptom resolution or improved QOL
    2. Minimal morbidity and mortality
    3. Modest resource utilization

Surgery for stage IV disease can be undertaken with curative
   intent
    1.   DFI > 12 months
    2.   Performance status
