Alternative Title:

Discussion regarding the poor long-term

results with CRS and HIPEC:

1. High PCI (concept of extent of disease)

2. Extensive prior surgery (concept of the

peritoneum as the first line of defense

against carcinomatosis)

3. Extensive prior systemic chemotherapy

(concept of natural or acquired drug

resistance)

Discussion regarding the poor long-term

results with CRS and HIPEC:

4. Inadequate perioperative hyperthermic

chemotherapy (concept of pharmacologic

drug selection).

5. Imperfect cytoreduction (concept of CRS

requiring visceral resections and

peritonectomy)

6. Lack of application to ovarian tumors of

low malignant potential (concept of

favorable tumor biology)

Bristow et al., 2007

Extent of disease and survival

Tentes et al., 2009

PCI <13 vs. >13

Are there modifications in patient

management that will result in a reduced

PCI at the time of CRS and HIPEC?

1. CRS + HIPEC as primary management

2. CRS + HIPEC after neoadjuvant

chemotherapy

3. ?

CONCEPT

The peritoneum is the first line of defense ofthe host against peritoneal dissemination ofcancer. If this barrier is disrupted in thepresence of cancer cells, fibrin entrapment atthe wounded site will cause progression deepto the peritoneum. Subsequent efforts totreat carcinomatosis by cytoreductive surgeryand peritonectomy with perioperativeintraperitoneal chemotherapy will bejeopardized.

Bidirectional chemotherapy (intraperitoneal

and intravenous)

Application to low malignant potential

(LMP) ovarian tumors with carcinomatosis

that have a less aggressive natural history

1. Low grade papillary serous

2. Mucinous ovarian

3. Granulosa cell

4. Gliomatosis peritonei

5. Pseudomyxoma from ruptured dermoid

cyst

Conclusions

1. The low perceived benefit from CRS

and HIPEC derives from poor patient

selection and suboptimal treatments.

2. Meticulous cytoreduction combined

with perioperative multidrug therapy

are needed in continuing phase II

explorations.

Advantages of moderate hyperthermic

intraoperative intraperitoneal chemotherapy

General

Reversal of systemic hypothermia from long surgery

Normalization of blood clotting

Minimal toxicity for normal tissue (<43ºC)

Potentiation of other therapies

Stimulation of host immune system

With chemotherapy

Increased cytotoxicity of chemotherapeutic agents

Increased drug penetration into tissue by increasing membrane permeability

Inhibition of chemotherapy repair mechanisms

Reversal of drug resistance

With manual distribution

Mechanical debridement of cancer cells from tissue surfaces

Uniform treatment of hyperthermia and chemotherapy solution

Absence of unexposed surfaces

Absence of suture line recurrence

Credits and debits of two different technologies for hyperthermic intraperitoneal chemotherapy

Open abdomen manually distributed Closed abdomen

EfficiencyAllows continued cytoreduction of bowel and

mesenteric surfacesNo surgery possible during chemotherapy

Environmental hazard No aerosols detected Perception of increased safety

Distribution

Uniform distribution of heat and chemotherapy

solutions, tissues close to skin edge not

immersed

Possible poor distribution to dependent sites and

closed spaces

Pressure No increased intraabdominal pressureIncreased intraabdominal pressure may increase

chemotherapy penetration into tissue

PharmacologyAllows pharmacokinetic monitoring of tumor and

normal tissueTissue uptake of chemotherapy cannot be determined

Abdominal incision and suture lines Treated prior to performing the suturingRisk of recurrence in abdominal incision and suture

lines

Diaphragm perforation with

peritonectomy

Pleural space treated by hyperthermic chemotherapy

may prevent seeding of pleural space

Diaphragm closed prior to hyperthermic

intraperitoneal chemotherapy so pleural space

is not treated

Intestinal perforation Detected by observing immersed bowel loops Not detected

Hyperthermia Increased heat necessary to maintain 42°C Less heat required to maintain 42°C

The peritoneum is the “First Line of Defense” for

cancer spread in the abdomen and pelvis.

Surgical interventions in the presence of free

intraperitoneal cancer cells can promote deep

implantation and jeopardize benefit from CRS

(Cytoreductive Surgery) and PIC (Perioperative

Intraperitoneal Chemotherapy).

Conclusions

1. A strong rationale from tumor biology

and the pharmacologic advantages of

local-regional chemotherapy combine to

recommend treatments to manage

carcinomatosis.

2. When treatments are available at

experienced centers CRS and PIC are

reasonable treatment options for

appendiceal cancer, mesothelioma and

low volume carcinomatosis.

3. Adjuvant perioperative intraperitoneal

chemotherapy has been found beneficial

in numerous single institution phase III

trials.

4. The standard of care for peritoneal

surface malignancy varies greatly around

the globe form experimental to standard

of care.
