Data demonstrating the efficacy of PIPAC in patients with regionally advanced gastric cancer with positive peritoneal cytology and/or minimal peritoneal disease is limited due to the relatively recent development of this technique and its historical preferential use in palliative patients with disseminated peritoneal metastasis.

Existing data suggest PIPAC administered every six weeks in conjunction with standard treatment may work as an adjunct to conventional systemic neoadjuvant chemotherapy. PIPAC protocols have been established both for gastric cancer as well as other intra-abdominal malignancies and have a good safety profile.

Given these promising findings, a study protocol is proposed herein to further investigate PIPAC for the treatment of a highly selected group of patients with regionally advanced gastric cancer (positive peritoneal cytology and/or minimal peritoneal disease).

BACKGROUND:

There remains therefore an important, and as yet unmet, clinic need to improve survival of patients with regionally advanced gastric cancer with positive peritoneal cytology and/or minimal peritoneal disease.

To address this challenge, there has been emerging interest in the use of intraperitoneal chemotherapy for the treatment and suppression of peritoneal disease in patients with regionally advance gastric cancer.

HYPOTHESIS:

Use of combined neoadjuvant systemic chemotherapy and PIPAC in a highly selected group of patients with locally advanced gastric cancer (positive cytology and/or minimal peritoneal disease) is safe and will effectively eradicate all traces of peritoneal metastasis.

STUDY DESIGN:

This will be a non-randomised interventional cohort study of patients with regionally advanced gastric cancer (Tx, Nx) with either positive peritoneal cytology and/or minimal peritoneal disease (peritoneal carcinomatosis index, PCI ≤ 3). All patients will undergo complete cancer staging, including laparoscopy.

Prior to enrolment Potentially eligible patient will be reviewed by the Northwest London Upper Gastrointestinal Cancer Multidisciplinary Team. Study recruitment will also be open to eligible patients referred from other regional cancer networks within England. Study recruitment will also be open to eligible patients referred from other regional cancer networks within England.

Eligible patients will receive systemic chemotherapy (in accordance with local protocols) and PIPAC (Doxorubicin 1.5 mg/m2 body surface area Cisplatin 7.5 mg/m2 body surface area). Patients will receive three cycles of systemic chemotherapy interposed with three PIPAC sessions. Chemotherapy cycles will be occur at six weekly intervals.

Following completion of neoadjuvant systemic chemotherapy and PIPAC patients will be restaged. Patients will be considered eligible for D2 radical gastrectomy if the following conditions are met:

(i) negative peritoneal cytology; (ii) absence of macroscopic peritoneal metastasis (PCI 0); (iii) absence of solid organ metastasis (for T4b disease please see point iv below); (iv) expectation of complete (R0) resection of primary tumour; (v) patient considered medically fit for gastrectomy (performance status ≤ 1, absence of organ failure or uncontrolled co-morbidity), and; (vi) provision of informed written consent for treatment (surgery)

Patients who do not meet these criteria will be offered continued palliative and/or best supportive care.

Barrier and mitigating factors or the provision of combined neoadjuvant systemic chemotherapy and PIPAC will be assessed. Safety of this intervention in terms of risks to patients and staff will also be evaluated.

Regression of peritoneal tumour deposits and/or positive peritoneal cytology. Regression will be assesses visually at the time of laparoscopy, by appropriate cross sectional imaging and through histological assessment of acquired samples.

Common Toxicity Criteria and Common Terminology Criteria for Adverse Events (Ver. 5) will be used to grade any complications that occur as a consequence of systemic chemotherapy and PIPAC administration. Surgical complications will reported using standard terminologies and graded using the Clavien-Dindo system.

Health related quality of life will be assessed using the European Organization for Research and Treatment of Cancer (EORTC) generic questionnaire QLQ-C30 (version 3.0).
