Patterns of disease relapse and posttreatment follow-up of patients with resected pancreatic adenocarcinoma: A single-center analysis.

Background And Objectives: To describe the patterns of disease relapse and follow-up of patients with resected pancreatic adenocarcinoma. Additionally, we looked at patients' characteristics at relapse and survival.

Methods: We included patients with potentially resectable pancreatic adenocarcinoma diagnosed from 2008 to 2018 who were submitted to resection with clear macroscopic margins and started posttreatment surveillance.

Symptomatic Recurrence and Survival Outcomes After Curative Treatment of Gastric Cancer: Does Intensive Follow-up Evaluation Improve Survival?

Background: Intensive surveillance after treatment of gastric cancer patients with curative intent may lead to an earlier diagnosis of disease recurrence, but its impact on survival is uncertain. This study aimed to evaluate whether early diagnosis of disease recurrence among asymptomatic patients was associated with long-term survival.

Methods: This retrospective study analyzed patients with stages 1 to 3C gastric adenocarcinoma treated between 1999 and 2018.

Does hipec improve outcomes in gastric cancer patients treated with perioperative chemotherapy and radical surgery? A propensity-score matched analysis.

Background: Hyperthermic intraperitoneal chemotherapy (HIPEC) has been associated with improved survival when compared with surgery alone for non-metastatic gastric cancer patients in randomized trials and meta-analyses. However, little evidence is available regarding the use of HIPEC in nonmetastatic patients who are treated with perioperative chemotherapy and radical surgery. The aim of this study was to investigate the putative survival benefit of HIPEC in the subgroup of gastric cancer patients treated with perioperative chemotherapy and surgery.

Survival outcomes of patients with pathological stage I gastric cancer using the competing risks survival method.

Background: Patients with stage I gastric cancer are considered to have an exquisite prognosis. Nonetheless, the fact that some patients experience disease relapse highlights that a subgroup might benefit from multimodality treatment. We aimed to evaluate the survival of patients with stage I gastric cancer and look for harbingers of gastric cancer recurrence.

Short-term outcomes after vascular resection for pancreatic tumors: Lessons learned from 72 cases from a single Brazilian Cancer Center.

Introduction: Pancreatic malignant tumors are resectable at diagnosis in only 15% to 20% of cases and invasion of vascular structures is commonly present. Therefore, extended resections are needed for adequate local control and negative margins. However, morbidity and mortality associated with these enlarged resections are limiting factors.

Impact of ypT, ypN, and Adjuvant Therapy on Survival in Gastric Cancer Patients Treated with Perioperative Chemotherapy and Radical Surgery.

Background: Perioperative chemotherapy and surgery is the standard of care in advanced gastroesophageal cancer patients, but its impact among those treated with radical surgery still needs further assessment. We present the results of this multimodality treatment approach in a gastric cancer patients cohort treated with D2 lymphadenectomy. We aimed to identify prognostic factors associated with improved survival.

Role of staging laparoscopy in the management of Pancreatic Duct Carcinoma (PDAC): Single-center experience from a tertiary hospital in Brazil.

Background: Proper staging is critical to the management of pancreatic ductal carcinoma (PDAC). Laparoscopy has been used to stage patients without gross metastatic disease with variable success.

Objectives: We aimed to identify the frequency of patients diagnosed by laparoscopy with occult metastatic disease.

Minimally invasive surgery for gastric cancer in Brazil: current status and perspectives-a report from the Brazilian Laparoscopic Oncologic Gastrectomy Group (BLOGG).

The minimally invasive surgery for gastric cancer in Brazil has begun about two years after the first laparoscopic gastrectomy (LG) performed by Kitano in Japan, in 1991. Although the report of first surgeries shows the year of 1993, there was no dissemination of the technique until the years 2010. At that time with the improvement of optical devices, laparoscopic instruments and with the publications coming from Asia, several Brazilian surgeons felt encouraged to go to Korea and Japan to learn the standardization of the LG.

Noncurative Resection for Gastric Cancer Patients: Who Could Benefit? : Determining Prognostic Factors for Patient Selection.

Background: Resections have long been recommended for patients with incurable gastric cancer. However, high morbidity rates and more efficient chemotherapy regimens have demanded more accurate patient selection. The aim of this study was to analyze the results of gastric cancer patients treated with noncurative resection in a single cancer center.

Total gastrectomy for gastric cancer: an analysis of postoperative and long-term outcomes through time: results of 413 consecutive cases in a single cancer center.

Background: Advanced gastric cancer in the upper or middle third of the stomach is routinely treated with a total gastrectomy, albeit in some cases with higher morbidity and mortality. The aim of this study was to describe the morbimortality and survival results in total gastrectomy in a single center.

Methods: This retrospective study included patients with gastric adenocarcinoma treated with a total gastrectomy at a single Brazilian cancer center between January 1988 and December 2011.

Safety and preliminary results of perioperative chemotherapy and hyperthermic intraperitoneal chemotherapy (HIPEC) for high-risk gastric cancer patients.

Background: Gastric cancer relapse occurs in about 30% of the patients treated with gastrectomy and D2-lymphadenectomy, mainly as distant or peritoneal metastases. Hyperthermic intraperitoneal chemotherapy (HIPEC) has been associated with an improvement in survival and lower peritoneal recurrence, albeit with increased morbidity. The aim of this study is to report the preliminary results of the association of perioperative chemotherapy, radical surgery and HIPEC in high-risk gastric patients in a single institution.
