Abstract

The predictive value of p53 and K-ras-2 mutational genotyping in determining tumor aggressiveness and survival in patients with endometrial carcinoma (EC) was retrospectively evaluated using a molecular genotyping approach on fixative treated tissue specimens. Two groups of patients with EC were selected based upon length of survival. Group A consisted of 14 patients that died within 3 years of initial diagnosis and treatment (mean survival of 1.1 years). Group B consisted of 18 patients that survived beyond 3 years (mean survival of 4.7 years). Clinicopathologic features including clinical stage, histologic type, and combined nuclear and architectural grade of each tumor were statistically analyzed with respect to oncogene/tumor suppressor gene alterations. The majority of carcinomas in group A were serous (57%), stage III or IV (93%), and high combined grade (93%). Group B consisted mostly of endometrioid (89%) and low-grade carcinomas (83%); 56.1% were stage III or IV. K-ras-2 point alterations were found in 2 (14%) and 4 (22%) patients from group A and B respectively; the spectrum of K-ras-2 genotypes was similar in both groups. p53 gene mutations were identified in 9 (64%) and 1 (6%) patient from group A and B respectively...Continue Reading

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
