Prognostic factors in renal cell carcinoma

چکیده
We studied 569 cases of renal cell carcinoma in the file5 of the Department of Pathology of the Nor~vegian Radium Hospital from 1964 to 1974. A nephrectorny had been perfornied in all cases. Clinical information on sex, age, survival time and metastases was traced. The histological slides were examined and turnour growth pattern, cell type, cell shape, nuclear atypia, abnormal nucleoli, nuclear grade, vasc~~ la r invasion and tumour demarcation mere all evaluated. Besides well-known prognostic factors j ~ ~ c h as tuniour stage, presence or absence of metastases and vascular invasion, nuclear grade \sas found to be a useful prognostic factor. Younger patients were found to do better than older, and women better than men. Smaller tumours carried a better prognosis than larger and clear cell turnours had a better prognosis than those composed of eosinophilic or basophilic cells. The presence of spindle cells was a bad prognostic omen.

Background and objective: Clear Cell Renal Cell Carcinoma (CCRCC) is the most common adult renal neoplasm. Staging and grading of RCC are important predictors of survival. Fuhrman nuclear grading is widely used for CCRCC, the subjective nature of which has prompted more objective methods to evaluate nuclear features. Furthermore, Ki-67, a reliable marker of cellular pr...
متن کاملQuick Score and H-Score Assessment of P504s (AMACR) Expression in Renal Cell Carcinoma (RCC) and Relation with Histologic Grade
Background and Aims: P504S (AMACR) is a mitochondrial enzyme expressed in renal cell carcinoma. Some of immunohistochemical markers in renal cell tumors are independent prognostic factor and show relation with histologic grading. AMACR expression increases with higher histological grading in different tumors; however, in RCC it is not obvious. In this study, we tried to investigate if ...

Approximately 90% of all head and neck malignancies and 94% of oral malignancies are squamous cell carcinoma (SCC). Tobacco smoking is considered as the most important causative agent for SCC. Despite aggressive and multidisciplinary treatment approaches, there has been no significant improvement in 5-year survival over the past 20 years. Several prognostic and predictive clinical, pathological...

Background and Aims: Immunohistochemical tests are one of the most important tests, which are under study to determine the prognosis of the cancers such as transitional cell carcinoma. By the time, flexible cystoscopy and urine cytology are the routine tests for following up the patients with transitional cell carcinoma, which are both operator dependent. On the other hand, cystoscopy is an inv...

The standard therapy for thyroid cancer is total or near total thyroidectomy, followed by the administration of radioactive iodine for remnant ablation or residual disease. Patients with radioiodine therapy are predisposed to second malignant neoplasms in organs such as central nervous system (CNS), breast, prostate, kidney, bone marrow, salivary gland, and digestive tract. Exposure to carcinog...
