UMF Tg. Mures Rezumat Aceas articol este o trecere in revista a datelor din literatura de specialitate privind managementul evaluarii cancerului esofagian si gastric si stadializarea. Toti pacientii care sunt luati in evidenta pentru interventia chirurgicala trebuie sa fie supusi unei evaluari a statusului fizic in principal a capacitatii performante si a functiei respiratorii. Pentru pacientii cu cancer gastric sau esofagian,stadializarea tumorilor la diagnostic este principalul factor determinant al supravietuirii.

Implicarea ganglionilor limfatici este cel mai important si singurul factor,urmat de stadiul T. Cuvinte cheie:cancer esofagian,stadiu tumoral,ganglioni limfatici Abstract This article is a review of the literature data on management gastric cancer tnm classification oesophageal gastric cancer assesement and staging. All patients being considered for surgery should undergo careful assessment of fitness with emphasis on performance status and respiratory function. For patients with gastric or oesophageal cancer, tumour stage at diagnosis is the main determinant gastric cancer tnm classification survival.
Lymph node involvement is the most important single factor, followed by T stage. Key words:oesophageal cancer,tumor stage,lymph node Introduction For patients with gastric or oesophageal cancer, tumour stage at diagnosis is the main determinant of survival.
The presence of more than four involved nodes or M1a node involvement is associated with significantly reduced survival, although it does not necessarily preclude long term gastric cancer tnm classification following resection.
Long term survival is not seen in patients with junctional cancers who have cervical nodal disease or nodal metastases in three body compartments neck, mediastinum and abdomen . In patients with gastric cancer both the number of involved nodes and the ratio of involved to uninvolved nodes significantly influence long term outcome.
T stage gastric cancer tnm classification the most significant factor in node negative cases. In patients with oesophageal cancer preoperative identification of lymph node involvement by EUS is associated with a poor prognosis.
Selected patients with T4 gastric cancer in the absence of extensive lymph node involvement can have long term survival five years and over following surgical resection[7,8]. The patients most likely to benefit from curative treatment are those without distant metastases and with limited lymph node involvement. Long term survival is possible in highly selected patients with more advanced disease but the majority of patients in this category will survive for less than two years following resection.
Oesophageal cancer should undergo careful preoperative staging to enable targeting of potentially curative treatment to those likely to benefit. B Patients with oesophageal cancer who have distant metastases or patients with oesophageal cancer who have metastatic lymph nodes in three compartments neck, mediastinum and abdomen on preoperative staging are not candidates for curative treatment.
C When M1a nodal involvement in oesophageal cancer, or extensive lymphadenopathy in any cancer, is identified on preoperative staging, the esophageal papilloma cancer cancer tnm classification poor prognosis should be carefully considered when discussing treatment options. Where there is clear evidence gastric cancer tnm classification incurable disease following staging, attempts at gastric cancer tnm classification should be avoided.
Tumor stage and quality of life There is no evidence directly addressing the influence of tumour stage on quality of gastric cancer tnm classification in gastric cancer tnm classification with oesophageal cancer.

Surgery results in a reduction in quality of life which only returns to preoperative levels in patients surviving more than two years. In these patients quality of life improves after three to four months and approaches preoperative levels at around nine months. D The possibility of reduction in quality of life after surgery should be considered when discussing treatment options, particularly when preoperative staging suggests that surgery would be unlikely to be curative.
Complications can be reduced by removing those patients at greatest risk from the surgical cohort.
Much more than documents.
This is most frequently achieved by exercising clinical judgement and there is evidence that this is predictive of in-hospital mortality.
The more objective POSSUM physiological and operative severity score for the enumeration of mortality and morbidity scoring system is also predictive of in-hospital death. Scoring systems for risk prediction specifically for patients with oesophageal cancer have been developed.
Use of a composite scoring system based on general performance status as well as cardiac, hepatic and respiratory function has been shown to reduce postoperative mortality from 9.
A simpler but unvalidated scoring system based on age, spirometry and performance status predicted an incrementally increasing risk of respiratory and cardiac complications although it did not predict postoperative mortality.
This measure of cardiopulmonary reserve is not routinely available. Gastric cancer tnm classification an American study of high-risk surgical patients, symptom-limited stair climbing predicted postoperative complications. The role of dynamic testing of cardiac function has not been addressed in patients with oesophageal cancers.
B All patients being considered for surgery should undergo careful assessment of fitness with emphasis on performance status and respiratory function. Accurate completion of pathology reports is essential to ensure accurate pathological staging for comparison with clinical stagingto inform assessment of prognosis, to indicate the completeness and adequacy of resection and to assist in audit. Important pathological parameters Resection specimens need to be dissected carefully for accurate tumour staging.

Tumour stage correlates with prognosis. The RCP standards also give information on the ideal preparation and dissection methods for resection specimens and the information which should be gastric cancer tnm classification for each resection. The following parameters have been identified as important in the RCP standards: Oesophageal, and junctional type I and II cancers — extent within the wall, longitudinal margins, vascular invasion and total number of lymph nodes and number and sites in which there is metastatic tumour.
The latter is important to identify M1 nodes as these are associated que hacer si tengo oxiuros a poor prognosis.
This Atlas illustrates the TNM classifications of all cancer sites and types included in the 7th Edition of the Manual and visually conceptualizes the TNM classifications and stage groupings.
Management of oesophageal and gastric cancer Treatment principles The choice of treatment for patients with oesophageal or gastric cancer depends on the stage of the disease, and on the condition and wishes of the patient. Patients with resectable lesions may be unfit for surgery or potentially curative chemoradiotherapy by virtue of significant comorbid disease.
The management of all patients should be discussed in an appropriate multidisciplinary meeting MDM where all staging and other relevant information is available gastric cancer tnm classification all members of the team.
Patients should be informed of the treatment options available surgery, chemotherapy or radiotherapyand these should be evaluated in terms of risks and benefits. The management of all patients who are diagnosed with gastric or oesophageal cancer, should be discussed within a multidisciplinary forum.
Stress associated with the diagnosis and treatment of cancer can cause significant psychological morbidity. Conclusion Health professionals providing care and treatment for patients with oesophageal or gastric cancer should seek appropriate training in communication skills.
D Information relating to local and national support services should be made available to both patients and carers. Patients should be given clear information relating to the potential risks and benefits of treatment.
