TL;DR: The cure rate after complete CRS of colorectal peritoneal carcinomatosis, followed by IPC, in selected patients is close to that obtained after resection of colOREctal liver metastases.
Abstract: Background:Although a randomized trial demonstrated a survival benefit of cytoreductive surgery (CRS) and intraperitoneal chemotherapy (IPC) over systemic chemotherapy alone, the treatment of peritoneal carcinomatosis from colorectal cancer (CRPC) is still a matter of debate.

TL;DR: This case-control study seems to confirm that prolonged survival can be achieved in highly selected patients operated on for limited PC and fewer than 3 LM.
Abstract: OBJECTIVE: This study aimed to assess the prognostic impact of liver metastases (LM) in patients with colorectal peritoneal carcinomatosis (PC) who underwent complete cytoreductive surgery and resection of LM, followed by intraperitoneal chemotherapy. BACKGROUND: Synchronous surgical treatment of PC and LM with curative intent remains controversial. METHODS: From a prospective database, all patients with PC and synchronous LM who had undergone cytoreductive surgery and LM resection followed by intraperitoneal chemotherapy were matched with patients with PC alone according to the following criteria: age, peritoneal cancer index (PCI), site and lymph node involvement (pN) of primary cancer, and postoperative chemotherapy. RESULTS: From 1993 to 2009, 37 patients with PC and LM were matched with 61 patients with PC alone. After a mean follow-up of 36 months, 3-year overall survival (OS) and disease-free survival rates were significantly lower in patients with PC and LM, respectively, 40% and 66% (P = 0.04) and 6% and 27% (P = 0.001). A PCI of 12 or more [odds ratio (OR): 4.6], a pN+ status (OR: 3.3), no adjuvant chemotherapy (OR: 3.0), and presence of LM (OR: 2.0) were identified as independent factors for poor OS. Three groups were singled out: (1) patients with a low PCI (<12) and no LM (median OS: 76 months); (2) patients with a low PCI (<12) and 1 or 2 LM (median OS: 40 months); and (3) patients with a high PCI (≥12) or patients with 3 LMs or more (median OS: 27 months). CONCLUSIONS: This case-control study seems to confirm that prolonged survival can be achieved in highly selected patients operated on for limited PC and fewer than 3 LM.

TL;DR: Zajac et al. show that in colorectal cancer, decreased TGF-β signalling promotes apical actomyosin contractility and collective apical budding of invading tumour spheres with inverted polarity that drive metastatic spread.
Abstract: Metastases account for 90% of cancer-related deaths; thus, it is vital to understand the biology of tumour dissemination. Here, we collected and monitored >50 patient specimens ex vivo to investigate the cell biology of colorectal cancer (CRC) metastatic spread to the peritoneum. This reveals an unpredicted mode of dissemination. Large clusters of cancer epithelial cells displaying a robust outward apical pole, which we termed tumour spheres with inverted polarity (TSIPs), were observed throughout the process of dissemination. TSIPs form and propagate through the collective apical budding of hypermethylated CRCs downstream of canonical and non-canonical transforming growth factor-β signalling. TSIPs maintain their apical-out topology and use actomyosin contractility to collectively invade three-dimensional extracellular matrices. TSIPs invade paired patient peritoneum explants, initiate metastases in mice xenograft models and correlate with adverse patient prognosis. Thus, despite their epithelial architecture and inverted topology TSIPs seem to drive the metastatic spread of hypermethylated CRCs.

TL;DR: Administration of bevacizumab before surgery with complete cytoreduction followed by HIPEC for colorectal carcinomatosis is associated with twofold increased morbidity.
Abstract: Background
Patients with stage IV colorectal cancer and peritoneal carcinomatosis are increasingly treated with curative intent and perioperative systemic chemotherapy combined with targeted therapy. The aim of this study was to analyze the potential impact of bevacizumab on early morbidity after cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with peritoneal carcinomatosis of colorectal origin.

TL;DR: Age, pre-operative radiation therapy, abdominoperineal resection, and surgery which fails to respect the "sacred planes" of TME are the four major risk factors for post-operative sexual and urinary sequelae.

TL;DR: This Review summarizes the main processes and new mechanisms involved in the formation of the pre-metastatic niche and describes the main mechanisms used to modify organs of future metastasis.
Abstract: It is well established that organs of future metastasis are not passive receivers of circulating tumour cells, but are instead selectively and actively modified by the primary tumour before metastatic spread has even occurred. Sowing the 'seeds' of metastasis requires the action of tumour-secreted factors and tumour-shed extracellular vesicles that enable the 'soil' at distant metastatic sites to encourage the outgrowth of incoming cancer cells. In this Review, we summarize the main processes and new mechanisms involved in the formation of the pre-metastatic niche.

TL;DR: This work proposes six characteristics that define the pre-metastatic niche, which enable tumor cell colonization and promote metastasis, including immunosuppression, inflammation, angiogenesis/vascular permeability, lymphangiogenesis, organotropism, and reprogramming.

TL;DR: This guideline attempts to improve a clinician's ability to evaluate and treat each patient, but higher quality evidence in future trials will be essential to improve level of care for these patients.

TL;DR: The usefulness of defective mismatch repair, BRAF, and KRAS mutations in predicting tumor recurrence and sensitivity to chemotherapy is investigated and MMR assays identify patients with a low risk of recurrence.
Abstract: Purpose It is uncertain whether modest benefits from adjuvant chemotherapy in stage II colorectal cancer justify the toxicity, cost, and inconvenience. We investigated the usefulness of defective mismatch repair (dMMR), BRAF, and KRAS mutations in predicting tumor recurrence and sensitivity to chemotherapy. Patients and Methods Immunohistochemistry for dMMR and pyrosequencing for KRAS/BRAF were performed for 1,913 patients randomly assigned between fluorouracil and folinic acid chemotherapy and no chemotherapy in the Quick and Simple and Reliable (QUASAR) trial. Results Twenty-six percent of 695 right-sided colon, 3% of 685 left-sided colon, and 1% of 407 rectal tumors were dMMR. Similarly, 17% of right colon, 2% of left colon, and 2% of rectal tumors were BRAF mutant. KRAS mutant tumors were more evenly distributed: 40% right colon, 28% left colon, and 36% rectal tumors. Recurrence rate for dMMR tumors was half that for MMR-proficient tumors (11% [25 of 218] v 26% [438 of 1,695] recurred; risk ratio [RR]...
