The chapter on molecular mechanisms of the formation of peritoneal carcinomatosis provides insight into a rapidly expanding knowledge within this speciality. This book should be valuable for surgical oncologists who deal with multimodal treatment for peritoneal surface malignancies, as well as for the trained peritonectomy surgeons. For the senior surgeons, it will also introduce new techniques and approaches in this field such as dealing with the omental cakes and massive organ involvement that requires multi-organ resection.
