Postoperative urinary dysfunction is a major complication of rectal cancer surgery. A randomized controlled trial (JCOG0212) concluded that the noninferiority of mesorectal excision alone to mesorectal excision with lateral lymph node dissection was not confirmed in terms of relapse-free survival. ⋯ Mesorectal excision with lateral lymph node dissection is not associated with a significant increase in the incidence of urinary dysfunction. Urinary dysfunction is associated with tumor location and blood loss.

Dutch national guidelines on the diagnosis and treatment of gastric cancer recommend the use of perioperative chemotherapy in patients with resectable gastric cancer. However, adjuvant chemotherapy is often not administered. The aim of this study was to evaluate hospital variation on the probability to receive adjuvant chemotherapy and to identify associated factors with special attention to postoperative complications. ⋯ Despite national guidelines, considerable hospital variation was observed in the probability of receiving adjuvant chemo(radio)therapy. Postoperative complications were strongly associated with adjuvant chemo(radio)therapy omission, underlining the need to further reduce perioperative morbidity in gastric cancer surgery.

Delaying surgery after neoadjuvant chemoradiotherapy in rectal cancer has no influence in surgical approach or short-term clinical outcomes.
In rectal cancer, increasing the interval between the end of neoadjuvant chemoradiotherapy (CRT) and surgery could improve the pathological complete response (pCR) rates, allow full-dose neoadjuvant chemotherapy, and select patients with a clinical complete response (cCR) for inclusion in a "watch & wait" program (W&W). However, controversy arises from waiting more than 8-12 weeks after CRT, as it might increase fibrosis around the total mesorectal excision (TME) plane potentially leading to technical difficulties and higher surgical morbidity. This study evaluates the type of surgical approach and short term post-operative outcomes in patients with rectal cancer that were operated before and after 12 weeks post CRT. ⋯ In our cohort, there was no difference in short term surgical outcomes between patients operated before or after 12 weeks following CRT. The type of surgical procedures and the proposed approach did not differ due to waiting after CRT. Delaying surgery by ≥ 12 weeks is safe, feasible and does not result in higher surgical morbidity.

Current practice in cytoreductive surgery and HIPEC for metastatic peritoneal disease: Spanish multicentric survey.
Radical Cytoreductive Surgery (CRS) with Hyperthermic Intraperitoneal Chemotherapy (HIPEC), has been proposed as the current standard of treatment for metastatic peritoneal disease by several tumors. Despite its widely utilization, there seems to be a great variability in their organization, clinical practice, and safety among centers. ⋯ Data showed an important variability in volume of patients per center, selection of cytostatic agents, professional training and safety measures applied. The standardization of CRS/HIPEC procedures based on the best available evidence, the individualization of patients and the consensus among professionals, constitute an important part of the basis that will allow us to improve results of this complex procedure.

Colorectal peritoneal carcinomatosis (PC) is commonly treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). There is an ongoing international debate about which intraperitoneal chemotherapeutic agent is preferred, Mitomycin C (MMC) or oxaliplatin. We questioned whether the type of chemotherapeutic agent influenced postoperative complication rates or short-term survival. ⋯ Intraperitoneal oxaliplatin reduced the chemoperfusion time when compared to intraperitoneal MMC without adversely influencing complication rates or short-term survival. It may therefore be the preferential drug in CRS-HIPEC procedures for colorectal PC.
