Survival Curve Renal Cell Carcinoma
Materials AND methods: The authors retrospectively analyzed the follow-up of 230 patients after radical or conservative renal surgery. B : Result of the final step, where only the APN/CD13 appears as an explanatory variable in the regression model.

surgical approach with more curative intent, especially for patients with localized metastatic disease 9,. Figure 4 A Kaplan-Meier survival curve of patients based on whether a pathologic fracture was present before the operation or not shows that presence of a pathologic fracture decreases the prognosis of the patient (p.001).
Perioperative variables collected were age and gender of the patient, type of surgery, complications, time period after first diagnosis of RCC and after onset of symptoms, metastatic pattern, location of metastases, incidence of pathologic fracture and local recurrence and time of survival. Various studies have reported an overall 5 years survival for patients with metastatic disease at 5-108 and 10 year surival of 0-74 Skinner4 has reported better survival for patients with grade IV disease with single metastatic lesion that is removed, surgically. Principal Investigator: Thai. They all have similar portential in predicting the prognosis. PubMed CrossRef Google Scholar. 2006, 144 (1 58-67. The immunohistochemical analysis was performed in 8 patients with exclusive sarcomatoid differentiation, confirming the presence of an epithelial component. Some evidence suggests that the sarcomatoid tumor is most often associated with chromophobe RCC (6 however, the histological type does not influence the disease's outcome (6,9,11).
Surveillance Strategies for Renal Cell Carcinoma Patients Following
Rochester, sylvester JL, long term results and prognostic factors. Tan, mayo Clinic, we believe one should aim for the widest resection of metastases as technically possible.
Long term follow-up is important as late appearance of metastases is not an entirely unknown phenomenon in RCC; 6 monthly chest x-ray, upper abdominal Ultrasound and liverfunction tests are optimum minimal tests for asymptomatic patients.

A clinical and pathological study of 309 cases. It is therefore, advisable that survival each hospital should survival have a single histological grading system, so that results could be compared even after long period of time.
If the diagnosis of metastasis was in question, a preoperative needle biopsy was obtained to confirm the histological diagnosis. Approximately one third of patients with newly diagnosed RCC have metastatic disease at the initial presentation.

The various parameters used to define response of RCC are not as clearly outlined as for certain other neoplasms. For pathological analysis, the specimen is fixed in formalin, embedded in paraffin, sectioned and fixed as usual by hematoxylin-eosin (HE). This is important for predicting the outcome for patients undergoing nephrectomy due to RCC, since adjuvant therapy in a certain group of patients with higher risk of progressive disease can be a reasonable alternative. Opinion concerning mixed cell type is that the prognois is better than spindle but worse compared to clear or granular.
Thus lymphadenectomy at the time of radical nepbrectomy is controversial, although theoretically it may be of some help in patients who have disease confined to the nodes that are surgically removed as part of radical nephretomy. J Bone Joint Surg. Inovlvement of lymph nodes, however, indicates systemic disease with a likelihood of distant metastases and survival failure to render patient free of micrometastases. Upon presentation, 87 were symptomatic, with pain, weight loss and hematuria being the most frequent complaints. Chemotherapy was used in 36 cases (35.6) (19 patients (18.8) preoperatively and 17 patients (16.8) postoperatively).
