Immigrant Health and Early-Onset Colorectal Cancer Disparities: Results From the Spanish Early-Onset Colorectal Cancer Consortium.

Purpose: To better understand immigration disparities among a Spanish Early-Onset Colorectal Cancer (SECOC) subset, according to the country of origin.

Patients And Methods: We selected 250 consecutive participants from the SECOC consortium. Data on baseline patient and tumor characteristics, family history of colorectal cancer (CRC), and follow-up were collected.

Ibero-American Consensus for the Management of Peritoneal Sarcomatosis: Updated Review and Clinical Recommendations.

Peritoneal sarcomatosis is a rare malignant disease with a poor prognosis, secondary to peritoneal dissemination of abdominopelvic soft tissue sarcomas. Its rarity, together with the characteristic histological heterogeneity and the historically poor response to systemic treatments, has prevented the establishment of widely accepted treatment criteria with curative intent. In this sense, radical cytoreductive surgery (CRS) with peritonectomy procedures and hyperthermic intraperitoneal chemotherapy (HIPEC), widely used in peritoneal carcinomatosis with excellent results, have not had the same evolutionary development in patients with peritoneal sarcomatosis.

Intestinal mucormycosis as a differential diagnosis of small bowel ischemia.

Intestinal mucormycosis is a rare manifestation of the Mucor fungus, associated with high mortality and typically found in immunocompromised patients, though it has also been described in immunocompetent individuals. The mode of acquisition is digestive. It usually presents as abdominal pain, with ischemia and intestinal perforation, and the diagnosis is often histopathological after surgical resection.

Robotic pelvic exenteration in males: systematization of the technique.

Male pelvic exenteration is a challenging procedure with high morbidity. In very selected cases, the robotic approach could make dissection easier and decrease morbidity due to the better vision provided and higher range of movements. In this paper, we describe port placement, instruments, minilaparotomy location, and the stepwise sequence of these procedures.

Sclerosing angiomatoid nodular transformation, a rare splenic tumor with increasing incidence.

SANT (sclerosing angiomatoid nodular transformation) tumor is a rare splenic tumor of unknown etiology and vascular lineage, first described in 2004. Most cases are asymptomatic, although cases of anemia or abdominal pain in association with growth have been described. Spontaneous ruptures have not been described.

Prioritization, patient selection, and multimodal perioperative management of colorectal cancer facing health-care system saturation.

Objective: The aim is to analyze the usefulness of pre-operative COVID-19 screening to detect asymptomatic patients, the capability of our patient selection algorithm to detect patients with more advanced tumors and the results of colorectal cancer surgery managed with a multimodal approach. We propose the use of a preoperative patient selection algorithm to prioritize the surgical treatment of patients with worse oncological prognosis and lower perioperative risk in situations of health system saturation.

Material And Methods: Prospective descriptive study including 71 patients operated on for colorectal cancer during COVID-19's high incidence period.

Liquid biopsy in peritoneal fluid and plasma as a prognostic factor in advanced colorectal and appendiceal tumors after complete cytoreduction and hyperthermic intraperitoneal chemotherapy.

Background: Positive cytology has been identified as an independent negative prognostic factor in patients with peritoneal metastases (PM) of colorectal origin. Liquid biopsy in plasma may detect increasing levels of circulating tumor DNA (ctDNA) and could help predict systemic relapse in patients with colorectal cancer, but little is known about the role of liquid biopsy in peritoneal fluid. The aim of this study was to evaluate the prognostic value of peritoneal fluid and plasma liquid biopsy in patients undergoing complete cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CC-HIPEC).

The impact of SARS-CoV-2 infection on the surgical management of colorectal cancer: lessons learned from a multicenter study in Spain.

Objective: the aim of the study was to analyze the management of colorectal cancer (CRC) patients diagnosed with CRC or undergoing elective surgery during the period of the SARS-CoV-2 pandemic.

Material And Methods: a multicenter ambispective analysis was performed in nine centers in Spain during a four-month period. Data were collected from every patient, including changes in treatments, referrals or delays in surgeries, changes in surgical approaches, postoperative outcomes and perioperative SARS-CoV-2 status.

Preoperative hepatic artery embolization before distal pancreatectomy plus celiac axis resection does not improve surgical results: A Spanish multicentre study.

Background: Distal pancreatectomy with celiac axis resection (DP-CAR) is a surgical procedure with high morbidity and mortality performed in patients with locally advanced pancreatic cancer. Preoperative embolization of hepatic artery (PHAE) has been postulated as a technical option to increase resection rate.

Objective: comparison of morbidity and mortality at 90 days, operative time, hospital stay and survival between patients that performed DP-CAR with and without PHAE.

Current use of molecular profiling for indeterminate thyroid nodules.

Even though cytology remains the gold standard to assess the nature of thyroid nodules, up to 30% of the results are indeterminate (BethesdaIII and IV). In these cases, current guidelines recommend performing diagnostic surgery, which proves malignancy in only 15-30% of cases. A more precise method is needed to avoid unnecessary surgeries, surgical complications and costs in the process of diagnosing indeterminate nodules.

Complete tubular colonic duplication in an adult: a rare incidental finding and the risk of colonoscopic perforation.

Gastrointestinal duplications are unusual congenital malformations, nearly always diagnosed in childhood. Roughly 80% are cysts-like lesions and only a small percentage (4-18%) involves the colonic wall. Almost all are asymptomatic and therefore diagnosed as an incidental finding on imaging tests or when become complicated and present with perforation or bleeding.
