The procedure can potentially prolong life and also improve quality of life for patients. A multidisciplinary team of health care professionals will carefully review your medical records and meet with you to determine if this operation may be an effective treatment for you. Two factors are critical for successful outcomes: First, careful patient selection to determine who may benefit the most with the least amount of risk, and second, performance of this operation at a busy national cancer center, such as The Johns Hopkins Hospital, by professionals experienced in the care of complex cancer patients.
Our multidisciplinary team consists of surgeons, oncologists, advanced practice providers, radiologists, anesthesiologists, nurses, nutritionists and social workers who are all dedicated to providing holistic care based on the best evidence to improve patient outcomes and the quality of life for people diagnosed with peritoneal carcinomatosis.
Skip Navigation. Peritoneal surface malignancy, commonly known as peritoneal carcinomatosis, is cancer within the peritoneal cavity. The peritoneal cavity is the space between the organs in the abdomen and is lined by the peritoneum, which is normally a thin protective membrane. Cancer of the peritoneum is often caused by the spread of cancer cells from pre-existing cancer.
The most common cancers that cause peritoneal carcinomatosis are:. Request an Appointment phone We work closely with our anesthesia colleagues to minimize discomfort after surgery. Two to three months is the average time that it takes for most patients to feel back to normal.

Fatigue is common as the body recovers from this complex surgery and gradually improves with daily activity and rest periods as needed. Nausea is managed with medications and gradually advancing your diet from liquids to solid foods.
Pain is managed with intravenous or epidural medications and, later, oral medications to achieve control. Loss of appetite is common and gradually improves by eating small frequent meals. Hair loss is temporary and usually improves with good nutrition and time. As with all major surgery, there are the standard risks of bleeding, infection and the effects of anesthesia. Most are minor, but some require further stay in the hospital for management. On average, patients are released on approximately day 8 or 9. Greer, Jonathan Bruce, M. These studies have shown that strict patient selection criteria are necessary.
Cytoreductive surgery must reduce the residual disease to a minimum for intraperitoneal chemotherapy to be effective due to minimal chemotherapy penetration. Yonemura et al. Hall et al. HIPEC with macroscopic disease burden does not improve survival more than 6 to 8 months. HIPEC can have morbidity and therefore should not be used for patients with bulky residual disease [ 46 ].
Palliative use for ascites may always be considered [ 45 , 47 ]. Figure 3. Overall survival of patients treated by cytoreductive surgery and hyperthermic intraperitoneal chemotherapy according to completeness of cytoreductive surgery. From Glehen et al. When the PCI was greater than 12, despite a complete cytoreduction there were no survivors greater than 3 years [Figure 4].

Overall survival of patients treated by complete cytoreductive surgery according to extent of peritoneal metastases assessed by the peritoneal cancer index. Yang et al. Median follow-up was 32 months and Median survival was 6. There was similar morbidity between the groups. The independent predictors in a multivariate analysis for improved survival were synchronous peritoneal metastases, CC cytoreduction, more than 6 cycles of systemic chemotherapy, and no adverse events. Also, the prognostic factors analyzed by Yang et al.
Even today with high technology radiology studies, diagnostic laparoscopy remains as an important tool to detect disease below a size threshold of approximately 1 cm [ 49 ]. If a gastric cancer patient is found to have macronodular small bowel disease or would otherwise not be able to be completely cytoreduced, HIPEC would not be warranted, and the morbidity of exploratory laparotomy could be avoided.
Recent randomized trials suggest that neoadjuvant chemotherapy should be used for gastric cancer patients free of peritoneal disease [ 52 ]. Laparoscopy may exclude patients with peritoneal metastases who would not benefit from aggressive neoadjuvant chemotherapy that is unlikely to improve their survival.
In medically fit patients with gastric cancer with peritoneal metastases systemic chemotherapy may be recommended. Chemotherapy can provide palliation, improve survival, and improve quality of life compared to best supportive care in patients with metastatic disease. However, the benefits of systemic chemotherapy in gastric cancer patients with peritoneal metastases may be reduced when compared to metastatic disease at other sites.
Preusser et al. Ajani et al. Systemic chemotherapy alone for primary gastric cancer with peritoneal metastases is a disappointing plan of management. Neoadjuvant chemotherapy for gastric cancer can be modified for patients with peritoneal seeding by combining systemic and intraperitoneal chemotherapy. Chemotherapy may gain access to small peritoneal cancer nodules via the systemic circulation and by diffusion from a chemotherapy solution within the peritoneal cavity.
They identified patients with peritoneal metastases by laparoscopy, laparotomy with biopsy or cytology from ascites. To qualify for NIPS, patients must have: 1 proven peritoneal seeding by histology or cytology; 2 no hematogenous or remote lymph node metastases; 3 be less than or equal to 65 years; 4 have an Eastern Clinical Oncology Group score of 2 or less; 5 adequate bone marrow, liver, cardiac, and renal function; and 6 no other severe medical comorbidities or synchronous malignancies. Qualifying patients had a peritoneal port system Bard Port, C.
Bard Inc. Prior to administration of chemotherapy, mL of saline was instilled into the peritoneal cavity and fluid was removed for cytology. Taxotere 40 mg and carboplatin mg were used for intraperitoneal chemotherapy in addition to mL of saline over 30 min. This regimen was administered weekly for two cycles. After the second cycle, peritoneal wash cytology was again performed. If cytology was positive, neoadjuvant chemotherapy was continued for 2 more cycles. Peritoneal cytology testing is repeating after the fourth cycle and the process is continued as long as cytology is positive.
If cytology became negative, upper endoscopy, laparoscopy and computed tomography scan was performed. If tumors showed no demonstrable change, then 2 more cycles were administered. The number of NIPS chemotherapy cycles was controlled by the effect on the primary cancer and peritoneal cytology. Complete cytoreduction was required for prolonged survival in prior studies that examined peritoneal metastases. Therefore, the goal of the NIPS regimen was complete or near complete response of metastases on small bowel surfaces [Figure 5].
Figure 5. Overall survival in gastric cancer patients with peritoneal carcinomatosis. From Canbay et al. Gastrectomy and peritonectomy were performed if peritoneal wash cytology became negative or there was a partial response to neoadjuvant chemotherapy. If peritoneal metastases on small bowel surfaces were eliminated by NIPS, there was a possibility that gastrectomy and parietal peritonectomy could achieve a complete cytoreduction.
Patients with progressive disease or who continue to have positive cytology despite 4 to 6 cycles of NIPS were not candidates for surgery.
Peritoneal Cancer: What You Need to Know
Sugarbaker [ 56 ] and Yonemura et al. Peritonectomies required for gastric cancer have been described [ 7 ]. The epigastric peritonectomy includes any prior midline abdominal scar with the preperitoneal epigastric fat pad, xiphoid process, round and falciform ligaments. The anterolateral peritonectomy removes the greater omentum with the anterior layer of peritoneum from the transverse mesocolon, peritoneum of the right paracolic gutter along the appendix, and the peritoneum in the right subhepatic space.
Sometimes the peritoneum of the right and left paracolic gutter must also be removed [Figure 6]. The subphrenic peritonectomy takes the peritoneal surfaces from the medial half of the right and left hemidiaphragm as well as the left triangular ligament [Figure 7]. The omental bursa peritonectomy starts with cholecystectomy and then removes the peritoneal covering of the porta hepatis, hepatoduodenal ligament, and floor of the omental bursa including the peritoneum overlying the pancreas [Figure 8]. If tumor was within the cul-de-sac, a pelvic peritonectomy was also performed and electroevaporative surgery strips the peritoneum from the pouch of Douglas.
Sometimes, the pelvic peritonectomy will necessitate removal of the rectosigmoid colon [Figure 9]. Some or all of these visceral resections and parietal peritonectomies were performed to completely remove visible disease. Figure 6. Anterolateral peritonectomy From Sugarbaker et al. Figure 7.
