Peritoneal carcinomatosis index and overall survival in patients taken to cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy.

Background: The peritoneal carcinomatosis (PC) secondary to gastrointestinal or gynecological cancer has increased its incidence. It has a worse prognosis compared to other sites of metastasis. The peritoneal carcinomatosis index (PCI) establishes overall survival in patients with gastrointestinal or gynecological tumors and carcinomatosis.

Surgical site infection following pancreaticoduodenectomy in a referral cancer center in Mexico.

Background: Pancreaticoduodenectomy is the standard treatment for resectable periampullary cancer. Surgical site infections (SSI) are common complications with increased morbidity. The study aimed to describe the prevalence, risk factors, microbiology, and outcomes of SSI among patients undergoing pancreaticoduodenectomy.

Solid and papillary neoplasm of the pancreas (SPNP): a case report.

Background: Solid and papillary neoplasm of the pancreas (SPNP) is a rare pancreatic tumor, well known for its predilection for young women and large volume. The tumor has a favorable prognosis and differentiating it from other pancreatic tumors with aggressive behavior is necessary.

Case Description: We present the case of a 34-year-old female without relevant background.

Prognostic importance of lymph node ratio after resection of ampullary carcinomas.

Background: The prognosis of the lymph node ratio (LNR) in Vater's ampulla carcinomas (VACs) is recently studied. However, there are not enough data in several populations like Latin American people. Our aim is to demonstrate the prognosis significance of the LNR in this setting.

Role of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in the treatment of gastric cancer.

Patients with peritoneal carcinomatosis (PC) of gastric origin have a poor prognosis of life with an average survival of 1-3 months. Systemic chemotherapy has improved the survival of those patients with gastric metastatic cancer at 7-10 months. However, this benefit could not be reproduced in those patients with PC.

Metastatic pheochromocytoma to liver without elevation of metanephrines and catecholamines.

Introduction: Malignant pheochromocytoma represents 10% of all patients with pheochromocytoma. Of these cases, only 5-9% presents without elevation of metanephrines and catecholamines.

Presentation Of Case: A 43-year-old female patient presented with an abdominal tumor.

Primary retroperitoneal Merkel cell carcinoma: Case report and literature review.

Background: Merkel cell carcinoma (MCC) is an aggressive cutaneous neuroendocrine carcinoma that affects elderly patients and typically arises in sun-exposed skin. The disease is very rare and only few cases present with no apparent skin lesion. In the retroperitoneum there are only two cases reported in the literature.

Gastric cancer in young people under 30 years of age: worse prognosis, or delay in diagnosis?

Background: Gastric cancer is an aggressive disease with nonspecific early symptoms. Its incidence and prognosis in young patients has shown considerable variability.

Purpose Of The Study: Our objective was to retrospectively study patients from our institution aged <30 years with gastric carcinoma.

Lung metastasectomy: long-term outcomes in an 18-year cohort from a single center.

Lung metastasectomy is an area of interest and controversy in surgical oncology. Most of the available evidence derives from small cohorts with short follow-up. The aim of this study was to evaluate the oncologic outcomes in an 18-year cohort from a single center.

[Malignant neoplasm in burn scar: Marjolin's ulcer. Report of two cases and review of the literature].

Background: Marjolin's ulcer forms part of a group of neoplasms that originate in a burn scar, a phenomenon associated with superficial tissue trauma. The frequency of Marjolin's ulcer is low and represents between 2 and 5% of all squamous cell carcinomas of the skin. This condition is found three times more frequently in men than in women and is thought to be more aggressive than conventional squamous cell carcinoma of the skin.

Practical aspects of intradialytic nutritional support.

A critical review of recent international literature related to the use of intradialytic parenteral nutrition is given. The role of intradialytic parenteral nutrition as a therapy in malnourished hemodialysis patients is established and the need for systematic monitoring of this population at high risk of malnutrition is emphasized.
