In a histopathological review of a total population, 1974 cases of endometrial carcinoma were found from 1970 to 1977. Of these 1566 (79.3%) were adenocarcinomas of the endometrioid type, 181 (9.2%) adenoacanthomas, 97 (4.9%) clear cell carcinomas, 74 (3.7%) adenosquamous carcinomas, 31 (1.6%) undifferentiated carcinomas, 22 (1.1%) serous papillary carcinomas and 3 (0.1%) squamous cell carcinomas. Thirty percent of the tumors were well differentiated, 44% moderately and 25.9% poorly differentiated. The mean age at diagnosis was 62.0 years (range 32-93 years). Age was clearly related to histologic type, grade and extent of myometrial infiltration. Crude 5- and 10-year survival rates for the entire group were 73.1 and 61%. For the different subtypes of endometrial carcinoma the 5- and 10-year crude survival rates were as follows: adenoacanthoma 91.2 and 79.6%, adenocarcinoma of the endometrioid type 74.1 and 62.2%, adenosquamous carcinoma 64.9 and 52.7%, undifferentiated carcinoma 58 and 48%, clear cell carcinoma 42.3 and 30.9% and serous papillary carcinoma 27 and 14%. All three patients with squamous cell carcinoma died within a year. The 5- and 10-year survival rates were 87.8 and 79.7% for grade 1 tumors, 76.6 and 62.1% for grade 2, and 60.1 and 48.6% for grade 3. The extent of myometrial infiltration was a string predictor of prognosis. The 5- and 10-year survival rates of patients with intramucosal tumors and tumors infiltrating the inner half of the myometrium were, respectively 89.6 and 82.5%, and 84.7 and 72.7%. Only 48.3 and 29.3% of the patients with tumors reaching the serosa survived, respectively 5 and 10 years. Patients without demonstrable vessel invasion had a significantly better prognosis than those with vessel invasion with a survival rate of 83.5 and 61.1% at 5- and 10-years, compared with 64.5 and 53.8%, respectively. Age at the time of diagnosis was an important prognostic factor for crude survival. Surgico-pathological staging was significantly better than clinical staging in predicting prognosis only in advanced stages.
BACKGROUND: Given the high burden of cervical cancer in low-income settings, there is a need for a convenient and affordable method for detecting and treating pre-cancerous lesions. METHODS: Samples for comparing the accuracy of cytology, virology and histology were collected. Identification of HPV E6/E7 mRNA was performed using PreTect HPV-Proofer. HPV DNA detection was performed by GP5 þ /6 þ PCR, followed by reverse line blot (RLB) for typing. RESULTS: A total of 343 women, aged 25 -60 years, attending gynaecological polyclinics in DR Congo were included for sample enrolment. The test positivity rate was conventional and liquid-based cytology (LBC) at cutoff ASCUS þ of 6.9 and 6.6%, respectively; PreTect HPV-Proofer of 7.3%; and consensus DNA PCR for 14 HR types of 18.5%. Sixteen cases of CIN2 þ lesions were identified. Of these, conventional cytology identified 66.7% with a specificity of 96.2%, LBC identified 73.3% with a specificity of 96.9%, all at cutoff ASCUS þ. HR-HPV DNA detected all CIN2 þ cases with a specificity of 85.9%, whereas PreTect HPV-Proofer gave a sensitivity of 81.3% and a specificity of 96.6%. CONCLUSION: Both HPV detection assays showed a higher sensitivity for CIN2 þ than did cytological methods. Detecting E6/E7 mRNA from only a subset of HR HPVs, as is the case with PreTect HPV-Proofer, resulted in a similar specificity to cytology and a significantly higher specificity than consensus HR HPV DNA (Po0.0001).
Antigen-primed T-cell blasts may be separated from alloreactive T cells on Percoll gradients. By means of this method, HLA restriction of antigen-specific proliferative T-cell responses may be studied, using allogeneic antigen-presenting cells carrying foreign D/DR antigens. The reported data confirm that the D/DR molecules as such are major restriction elements in the T-cell response to herpes simplex virus (HSV) and purified protein derivative (PPD). However, evidence is presented that other Class II HLA molecules, the MT molecules, may also function as restriction elements for the HSV response.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
