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 – “We want actual not virtual data” AH Harken 6am lab mtng 2000
“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
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
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
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
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 Krouse Arch Surg 2001
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 Krouse Arch Surg 2001
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. Cullinane CA Cancer 2003
Resource utilization for ovarian cancer patients at the end of life: How much is too much? 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. Lewin SN Gyn Oncol 2005
Resource utilization for ovarian cancer patients at the end of life: How much is too much? Results: 67 non-hospice and 17 hospice • equivalent – histology, stage, platinum sensitivity, mean number of chemotherapy cycles 26% reduction Survival for the two groups was the same Lewin SN Gyn Oncol 2005
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% “Mobile Happy Hour”
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
Palliative Surgery Metastectomy/Palliative Early stage disease Surgery Risk Benefit Risk Benefit Surgeon’s role: 1. initial evaluation of the disease 2. local control 3. control of discharge and hemorrhage 4. control of pain 5. reconstruction and rehabilitation
Palliative Surgery-Defined • 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
Palliative Surgery Grade ECOG/WHO Major Surgery 0 Fully active, able to carry on all pre-disease performance without restriction 1 Restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature, Yes e.g., light house work, office work 2 Ambulatory and capable of all self-care but unable to carry out any work activities. Up and about more than 50% of waking hours 3 Capable of only limited self-care, confined to bed or chair Maybe more than 50% of waking hours 4 Completely disabled. Cannot carry on any self-care. Totally No confined to bed or chair – “Ah he’s only mostly dead and mostly dead is partly alive.” – Princess Bride. 5 Dead – “The difference between alive and dead is dead can’t fog the mirror.” – Nathan W. Pearlman, MD
A Prospective, Symptom Related, Outcomes Analysis of 1022 Palliative Procedures for advanced Cancer • The goal: – “to prospectively follow all patients undergoing a palliative operative or endoscopic procedure during a one year period to obtain some of the data that are required to guide sound clinical decisions and allow more adequate patient counseling.” Miner Ann Surg 2004
A Prospective, Symptom Related, Outcomes Analysis of 1022 Palliative Procedures for advanced Cancer • Results: • Documented improvement in – 823 initial procedures 80% – 109 for recurrence – Median 135 days – 90 for new sx’s. – Complication vs. none: – Overall mortality – 11% 67% vs. 89%, (p

A Prospective, Symptom Related, Outcomes Analysis of 1022 Palliative Procedures for advanced Cancer • 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 Miner Ann Surg 2004
Palliative Surgery • Miner TJ et al Defining • Similar findings Palliative Surgery in – Palliation is achievable with Patients Receiving great success Noncurative Resections – Durability of palliation is for Gastric Cancer. JACS short due to development of new symptoms 2004 – Age, gross residual • Miner TJ et al Symptom disease, pain and Control in Patients With recurrence of local disease Locally Recurrent Rectal (rectal) were predictors of Cancer.

ECOG 3. • OR – Ex lap, en bloc resection of distal panc, spleen, splenic flexure, left kidney, and diaphragm • DC home in 2 weeks • 1 mo. later brain mets and Would she have done better with a palliative bypass? peritoneal recurrence “Whenever a man does a thoroughly • 3 weeks later died stupid thing, it is always from the noblest motives.” Oscar Wilde
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.” Cady Arch Surg 1997
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 Balch CM. J Am Acad Dermatol 1980
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. Balch J Clin Oncol 1983 Allen ASO 2002
Stage IV melanoma - Lung Group 5yr (%) 3 Prognostic N=328 pts pulmonary signs metastsectomy I 29% CR, DFI>36 mos and single met II 20% CR and one unfavorable III 7% CR and two unfavorable IV 0% Incomplete resection Median 19 vs. 11 mos, p
Stage IV melanoma – GI tract • N=68 pts explored • Group I curative resection • Anemia 60% and pain 59% • Group II residual disease 14.9 vs. 6.9 mos median survival Median = 6.9 mos 5 yr = 18% Curative Residual disease Agrawal S ASO 1999
Stage IV Cancers and Metastectomy Author Year N Site/disease Predictors of survival Pawlik 2007 52 Liver/SCCA Complete resection, longer DFI, Size12mos Fong 1999 1001 Liver/colorectal Complete resection, DFI>12mos, Liver only, Tumor number, node (-) 10, Met< 5cm, CEA
Liver Metastectomy and Pancreatic Cancer? • N = 22 patients with low volume synchronous liver mets (86% solitary) • Results – Whipple (no mets) - 14.2 mos median – Palliative bypass – 5.6 mos median – Whipple + liver resection – 5.9 mos median • Conclude – Even with well selected patients biology wins with metastectomy and pancreatic cancer.

Peritoneal Surface Disease from Colorectal Cancer: Comparison with the Hepatic Metastases Surgical Paradigm in Optimally Resected Patients • 121 IPHP vs. 101 Liver • Completeness of resections cytoreduction • Compared R0/R1 IPHP – R0, complete removal of all vs. R0 Liver resections visible tumor and negative cytology or microscopic – Morbidity and mortality margins – Overall survival – R1, complete removal of all visible tumor and positive cytology or microscopic margins – R2a < 5mm – R2b 5mm – 2cm – R2c >2cm Shen Ann Surg Oncol 2008
Peritoneal Surface Disease from Colorectal Cancer: Comparison with the Hepatic Metastases Surgical Paradigm in Optimally Resected Patients • M&M (PSD vs. HM) – 48.1% vs. 33.7% (p=0.38) – 5.5% vs. 4.2% (p=0.71) 41 mos • MV predictors 34 mos – Resection status, obstruciton, malignant ascites and LOS Concluded: R0/R1 resection during IPHC compared with margin-negative 5yr OS was 26% vs. 34% hepatic resection demonstrated no significant difference in OS and should be considered a viable treatment option. Shen Ann Surg Oncol 2008
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
Removing the Primary and Survival Author Year N Disease Conclusions (resected) Saidi 2006 105(24) Gastric Improves OS (13.2 vs. 5.5 mos) Field 2007 409 (187) Breast Improves OS(31.9 vs 15.4 mos), not metastatic PFS Babiera 2006 224(87) Breast Improves metastatic PFS (p=0.001) and trend toward OS (p=.1) Blanchard 2008 395(242) Breast Improves OS (27.1 vs.16.8 mos)

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 1.

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
