Electroacupuncture in Symptom Management After Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy

The investigators are conducting this research study is to evaluate the feasibility (recruitment, compliance, safety, and acceptance) of using electroacupuncture (EA) to manage complex symptoms such as pain, nausea/vomiting, diarrhea, and insomnia in patients who have undergone Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy. Additionally, the investigators are aiming to determine the effectiveness of EA in reducing these symptoms, and to examine how EA impacts important biomarkers, or proteins in the blood, that can be used as indicators or signs of these symptoms.

This is a single-arm, prospective pilot/feasibility study. Patients can be enrolled at any time prior to undergoing surgery. The protocol and interventions are as described in the above schema. Baseline assessments including the above surveys and inflammatory markers will be obtained at the preoperative visit. The same assessments will be performed at approximately 1 month s/p Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy. Electroacupuncture interventions will be performed between postoperative months 1 to 3; a total of 8 weekly interventions will be performed. A completion assessment will be performed at approximately 6 months s/p Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy.

Our specific aims are as follows:

To examine the feasibility of utilizing an EA protocol in patients who have undergone Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy.

To characterize symptoms experienced by patients during recovery from Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy.

To evaluate the utilization of EA in symptom management during recovery from Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy.

To evaluate levels of biomarkers such as circulating brain-derived neurotrophic factor, pro-inflammatory cytokines (IL-1beta, IL-4, IL-6, IL-8, IL-10, Tumor necrosis factor-alpha), mitochondrial DNA after Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy and with utilization of EA.

Eligibility Criteria:
Inclusion Criteria:

* Patients with known peritoneal disease who are scheduled to undergo Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy
* Age ≥18 years
* Eastern Cooperative Oncology Group performance status ≤2
* Patients must have adequate organ and marrow function as defined through laboratory tests
* Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial
* For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
* Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load

* Patients with uncontrolled intercurrent illness
* Severe needle phobia
* Patients with psychiatric illness/social situations that would limit compliance with study requirements
* Known bleeding disorder (e.g. hemophilia, Von Willebrand's disease, thrombocytopenia)
* Pacemaker or other electronic metal implants
