The pelvis in addition to containing the ends of the GI (sigmoid, rectum), urinary (distal ureters, bladder) tract, and the gynecological organs (ovaries, uterine tubes, uterus), it also contains the connection and continuity of the skeleton and of the vascular and peripheral nervous system of the trunk to the lower extremities. As such, in this broadest definition of pelvis, the issue will provide a comprehensive, exhaustive account of the surgical treatment of tumors in any pelvic location. Surgical treatment of pelvic tumors has advanced as in other anatomical areas through the progressive incorporation of other adjuvant modalities; the application of the rising knowledge in tumor biology as guidance to the extent of surgery; the restriction of surgical treatment to what is the practically minimum required in the context of combination of modalities; the development of new techniques and approaches in the complete resection of tumors considered unresectable up to the recent past.

We invite investigators to contribute original as well as review articles, which will present that state-of-the-art surgical treatment of tumors in various pelvic locations and the use of adjuvant modalities. Potential topics include but are not limited to:

• Adenocarcinoma of the sigmoid or cecum fixed to the left or iliac fascia and/or lower abdominal wall
• Technique of resection of mesorectum
• Carcinoma of the midrectum fixed to the sacrum
• Primary tumors of the sacrum (respectability approaches).
• Bilateral pelvic lymph node dissection from the obturator foramina below the infrarenal nodes above
• Lateral pelvic wall infiltration in GYN or other tumors (features determining their resectability)
• Pelvic tumors involving the pubic bone and/or extending through the obturator foramina in the adductor group
• Sarcomas of the iliac fossa extending to the groin without bone involvement
• Sarcomas involving the iliac bone or the entire innominate bone (internal hemipelvectomy)
• External hemipelvectomy for pelvic for pelvic tumors
• Anterior-posterior pelvic exenteration
• Adjuvant and neoadjuvant treatments for pelvic tumors
