BACKGROUND: Neuroendocrine tumors (NETs) are rare, comprising nearly 0.49% of all malignancies. The majority occurs in the gastrointestinal tract. AIM: To analyze the demographic factors, clinicopathologic features, treatment employed, prognostic factors and the oncologic results related to colorectal NETs. METHODS: Between the period from 1996 to 2010 174 patients were treated. From these, 34 were localized in the colon and rectum. Demographic factors, stage, therapeutics and its results were analyzed. All patients were followed for more than three years with image exams, urinary 5-hydroxyindolacetic acid (5-HIIA), serum chromogranin A and prostatic acid phosphatase. RESULTS: The median age was 54,4 years (22-76), the majority was female (64,7%). Out of the 12 patients with colon NETs, one (8.3%) patient was classified as Stage IA; one (8.3%) as Stage IB; three (25%) as Stage IIIB and seven (58.4%) as Stage IV. Out of the 22 patients with rectum NETs, six (27.3%) were classified as Stage IA; four (18.2%) as IB; three (13.6 %) as IIIA; one (4.5%) as IIIB and eight (36.4%) as IV. Of rectal NETs, nine (41%) were treated with endoscopic resection, six (27.2%) underwent conventional surgical treatment and six (27.2%) were treated with chemotherapy. Eleven patients with colon NETs (91.6%) were surgically treated, seven of them with palliative surgery, one (8.4%) was treated with endoscopic resection and no patient was submitted to chemotherapy. After an average follow-up of 55 months, 19 (55%) patients were alive. Analyzing the overall survival was obtained an average overall survival of 29 months in Stage IA, 62 months in IB, 12 months in IIIA, 31 months in IIIB and 39 months in IV. CONCLUSION: The treatment of colon and rectal NETs is complex, because it depends of the individuality of each patient. With adequate management, the prognosis can be favorable with long survival, but it is related to the tumor differentiation degree, efficacy of the chosen treatment and to the patient adhesion to the follow-up after treatment.
Peptic ulcer is a lesion of the mucosal lining of the upper gastrointestinal tract characterized by an imbalance between aggressive and protective factors of the mucosa, having H. pylori as the main etiologic factor. Dietotherapy is important in the prevention and treatment of this disease.
To update nutritional therapy in adults' peptic ulcer.
Exploratory review without restrictions with primary sources indexed in Scielo, PubMed, Medline, ISI, and Scopus databases.
Dietotherapy, as well as caloric distribution, should be adjusted to the patient's needs aiming to normalize the nutritional status and promote healing. Recommended nutrients can be different in the acute phase and in the recovery phase, and there is a greater need of protein and some micronutrients, such as vitamin A, zinc, selenium, and vitamin C in the recovery phase. In addition, some studies have shown that vitamin C has a beneficial effect in eradication of H. pylori. Fibers and probiotics also play a important role in the treatment of peptic ulcer, because they reduce the side effects of antibiotics and help reduce treatment time.
A balanced diet is vital in the treatment of peptic ulcer, once food can prevent, treat or even alleviate the symptoms involving this pathology. However, there are few papers that innovate dietotherapy; so additional studies addressing more specifically the dietotherapy for treatment of peptic ulcer are necessary.
Acute pancreatitis is an inflammatory disease of the pancreas due to enzymatic autodigestion which can cause necrosis or multiple organ failure; its pathophysiology is not fully known yet.
To evaluate the correlation between clinical and therapeutic data in patients with mild acute pancreatitis.
A retrospective study in 55 medical records of patients admitted with acute mild pancreatitis was realized to analyze the association between age, leukocytosis, serum glutamic-oxaloacetic transaminase and lactate dehydrogenase, glucose, antibiotics, time admission and Ranson´s scores.
There was a positive association between less intensive care (strict hydration, analgesia and monitoring of vital signs), early antibiotic therapy (monotherapy), early return to diet after 48 hours and laboratory control of the serum amylase and lipase (high in the first week and decreasing after 10 days, without any prognostic value).
Changes in the management of patients with mild acute pancreatitis, such as enteral nutrition, rational use of lower spectrum antibiotics and intensive care, have contributed significantly to the reduction of hospitalization time and mortality.
The frequency of gastric neuroendocrine tumors is increasing. Reasons are the popularization of endoscopy and its technical refinements. Despite this, they are still poorly understood and have complex management.
Update the knowledge on gastric neuroendocrine tumor and expose the future perspectives on the diagnosis and treatment of this disease.
Literature review using the following databases: Medline/PubMed, Cochrane Library and SciELO. Search terms were: gastric carcinoid, gastric neuroendocrine tumor, treatment. From the selected articles, 38 were included in this review.
Gastric neuroendocrine tumors are classified in four clinical types. Correct identification of the clinical type and histological grade is fundamental, since treatment varies accordingly and defines survival.
Gastric neuroendocrine tumors comprise different subtypes with distinct management and prognosis. Correct identification allows for a tailored therapy. Further studies will clarify the diseases biology and improve its treatment.
The complexity of the management of gastric cancer requires a multidisciplinary evaluation of patients with this tumor. Several treatments have been employed, associated to the surgical resection.
To review the available therapeutic alternatives for the treatment of gastric adenocarcinoma.
A review of selected articles on multidisciplinary treatment of gastric adenocarcinoma in the Pubmed and Medline databases between 2000 and 2017 was carried out. The following headings were related: stomach cancer, treatment, chemotherapy and radiotherapy.
There are several valid alternatives, with good results for the treatment of gastric cancer: chemoradiotherapy or chemotherapy in the adjuvant scenario; perioperative chemotherapy; and chemoradiotherapy after neoadjuvance with isolated chemotherapy.
Current evidences suggest that combined multidisciplinary treatment is superior to surgery alone. However, the optimal treatment regimen is not yet established, and depends on a number of factors, especially the type of surgical resection employed. Therefore, the therapeutic decision should be made by a multidisciplinary team, assessing patient’s personal characteristics, biology of the tumor, residual disease, risks and side effects.
