Complete cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy is the standard of care for mucinous appendiceal neoplasms with peritoneal metastases. Despite many publications reg...
A retrospective analysis of prospective, histologic, and perioperative data was performed. Overall survival was the endpoint for the numerous assessments. Judgments regarding when to and when not to p...
From a database of 949 patients who underwent an index CRS for appendiceal mucinous neoplasm, 264 patients (27.8%) had an incomplete CRS. The median overall survival was 1.8 years. Low-grade histopath...
When a surgeon is confronted by a procedure that will inevitably end with an incomplete CRS, a current trend is to close quickly and always avoid complications. Patients with low-grade neoplasms who p...
Incomplete cytoreduction for mucinous appendiceal neoplasms is often required to temporarily alleviate symptoms. The surgical technology for this intervention may be complex and result in extensive mo...
A database was used to identify patients who had palliative surgery that included total abdominal colectomy (TAC). Clinical- and treatment-related variables were assessed for their impact on overall s...
Seventy-eight patients had an incomplete cytoreductive surgery (CRS) that included a TAC. The median survival was 2.5 years and the median follow-up was 2 years. Patients with symptoms of abdominal di...
TAC with end ileostomy was used as a treatment option to provide palliation of patients having an incomplete CRS for appendiceal mucinous neoplasms. With LAMN or MACA-Int, median survival was 5.0 year...
Cystic mesothelioma, also known as benign multicystic peritoneal mesothelioma (BMPM), is a rare neoplasm and one of the five main histological types of peritoneal mesothelioma. Although it is usually ...
Peritoneal metastases (PMs) following resection of pancreatic intraductal papillary mucinous neoplasms (IPMNs) are rare. Consequently, prevalence, risk factors, and prognosis are not well known. We re...
All pancreatectomy cases (556 patients) performed at a tertiary care center between 2010 and 2020 were reviewed to identify IPMN diagnoses. Patients with adenocarcinoma not arising from IPMN, or a his...
Seventy-eight patients underwent pancreatectomy with IPMN on final pathology at our institution; 51 met inclusion criteria. Of these, there were five cases of PMs (4:1 females:males). Four had invasiv...
PMs following IPMN resection are rare but may be more common in patients with invasive histology. Although rare, PMs can arise in patients with noninvasive IPMNs. Further studies on pathophysiology an...
There is a paucity of targeted therapies for patients with pseudomyxoma peritonei (PMP) secondary to low-grade appendiceal mucinous neoplasms (LAMNs). Dysregulated metabolism has emerged as a hallmark...
Tumors were washed with phosphate-buffered saline (PBS), microdissected, then dissociated in ice-cold methanol dried and reconstituted in pyridine. Samples were derivatized in tert-butyldimethylsilyl ...
Eight peritoneal tumor samples were obtained and analyzed: LAMNs (4), and moderate to poorly differentiated adenocarcinoma (colon [1], appendix [3]). Decreases in pyroglutamate, fumarate, and cysteine...
Distinct metabolic signatures may exist for PM from LAMN versus adenocarcinoma. A multitude of genes are differentially regulated, many of which are involved in metabolic pathways. Additional research...
Programmed death-1 (PD-1) and T cell immunoglobulin and mucin-domain-containing molecule 3(Tim-3) may be used as the biomarkers for the therapy in patients with peritoneal neoplasms. In the current st...
115 patients with peritoneal neoplasms were recruited, subjected to multicolor flow cytometric analyses of the percentages of PD-1 and Tim-3 receptors of circulating Lymphocytes, CD3 + T cells, CD3 + ...
Higher levels of CD4 + T lymphocytes, CD8 + T lymphocytes, CD45 + PD-1 + lymphocytes, CD3 + PD-1 + T cells, CD3 + CD4 + PD-1 + T cells, CD3 + CD8 + PD-1 + T cells and CD45 + Tim-3 + lymphocytes were f...
Our work uncovers peripheral PD-1 and Tim-3 percentages are associated with primary sites and pathological types of peritoneal neoplasms. Those findings might provide important assessment to predict p...
Cytoreductive surgery (CRS) and perioperative intraperitoneal chemotherapy are currently the standard of care for management of appendiceal mucinous neoplasms with peritoneal metastases. The goal of t...
From a database and secured files of patients having a complete CRS, all patients who had TAC were identified. The clinical and histologic variables associated with these patients were identified and ...
The 450 complete CRS with low-grade appendiceal mucinous neoplasms had 26 TAC (5.8%) with a 16.0-year median survival. The mucinous adenocarcinoma (MACA)-Intermediate (MACA-Int) group consisted of 37 ...
Complete CRS required TAC in 56 of 646 patients (8.7%) with appendiceal mucinous neoplasms. With TAC, median survival was 12.0 years. A class 4 adverse event markedly reduced survival....
Patients treated surgically for local non-invasive mucinous appendiceal neoplasm (NI-MAN) may recur with the development of peritoneal dissemination (PD). The risk of recurrence and predictive factors...
A focal adenomatoid-microcystic pattern is not uncommon in peritoneal mesothelioma, but tumors composed almost exclusively of this pattern are distinctly rare and have not been well characterized. A s...
Survival of patients affected by mucinous appendiceal neoplasms with peritoneal dissemination (PD) is mainly related to histopathological features. However, prognostic stratification is still a concer...
Patients treated in two referral centers were included: Hospital General Universitario Gregorio Marañón, Madrid, Spain (derivation cohort) and Fondazione IRCCS Istituto Nazionale Tumori, Milan, Italy ...
The derivation cohort included 95 patients, and the validation cohort 348. Five-year DFS rates were 51.5 and 62%, respectively. Cox regression analysis (derivation cohort) identified PSOGI histology o...
An easy-to-use model that provides better prognostic stratification than histopathological features has been constructed. This nomogram may help clinicians in individualized survival predictions and i...
