Welcome to PROMISE evaluation

PeRitOneal MalIgnancy Stage Evaluation (PROMISE) internet application offers computer-assistance to produce simple, quick but precise and standardized pre, intra and postoperative reports of the extent of peritoneal metastases and may help specialized and non-specialized institutions in their current practice but also facilitate research and multicentre studies on peritoneal surface malignancies.
Based on the importance of assessing the true extent of peritoneal disease, the PROMISE application has been developed to facilitate tabulation and automatically calculate peritoneal cancer index (PCI) and other surgically validated scores as Gilly score, Simplified PCI, Fagotti and Fagotti-modified scores for ovarian cancers.

Tumour type must first be selected (colorectal, ovarian, appendix, gastric, pseudomyxoma peritonei, peritoneal mesothelioma and other) and then, from a fixed list of required data elements, the capture of data is facilitated by the PROMISE application for each type of evaluation:
- After a complete intraperitoneal exploration, the surgeons report the peritoneal metastases distribution in each of the 13 regions by clicking on the number and size of peritoneal implants or thickenings, the anatomical structure involved and the presence of peritoneal fluid. Surgeons can also report non resectable lesions, lymph nodes and extra peritoneal lesions.
- Radiologists have dedicated screens for each imaging modality. Each screen is designed with the same presentation as the surgical fields but also with specific radiological fields taking into account the different imaging modality parameters (apparent diffusion coefficient (ADC) for Diffusion MRI, standard uptake value (SUV) for 18 FDG PET-CT …).
- For the pathologist, the histopathological specimens taken in theatre are carefully orientated with anatomical landmarks to aid uniform assessment with both radiological and surgical findings.
- Finally, data summary of the extent of peritoneal metastases can be saved as a pdf file or printed and attached to the radiological, surgical and pathological reports, or exported to an Excel database for institutional research.

It is a free Lite version, also free of copyright which we hope will encourage wide adoption and eventually some degree of standardaziation within multidisciplinary teams and between centres that treat patients with peritoneal malignancy.
