Second diagnostic laparoscopy – Restaging after IPC
CMT
PRIMARY TUMOR, DISEASE
After the end of the IPC and systemic CMT, patients will be reassessed through clinical and radiological examination, with CT of the chest, abdomen, and pelvis. Those who do not present radiological evidence of disease and maintain ECOG 0 and 1 will undergo a second diagnostic laparoscopy to assess the peritoneal response.Patients who present a complete response to PC confirmed in LS (negative biopsy of lesions in the peritoneum with negative cytology) and have a primary tumor with potential R0 resection will be submitted to gastrectomy (conversion surgery). After surgery, patients will continue to CMT with XP until cycle 8. Those who present partial response or absence of peritoneal response will have the catheter removed, continuing the standard palliative CMT treatment at the institution.
