Mucin-like carcinoma-associated antigen (MCA) in tissue and serum of patients with breast cancer: clinical applications in prognosis and disease monitoring.

Mucin-like Carcinoma-associated Antigen (MCA) has been associated with many breast cancers. The aim of this study was to evaluate MCA in tumor tissue and serum as a potential tumor marker for prognosis and disease monitoring. MCA levels were determined in the tissue of 196 patients with primary breast cancer, 25 with metastatic disease and 25 patients with benign diseases, in pellet and/or cytosol. MCA levels were also determined in the serum of 50 patients with benign diseases, 148 with primary breast cancer (Mo), 150 with metastatic breast cancer (MT), and 200 with no clinical evidence of disease (NED). MCA tissue concentrations in pellet and cytosol were similar: 66.7 + 251 U/mg and 41.1 + 53 U/mg, respectively. No relationship between MCA levels and tumor size or nodal involvement was found. Higher MCA levels were observed in patients with ER+ or PgR+ tumors than in those with ER- or PgR- tumors (p < 0.01). Patients with MCA pellet concentrations lower than 10 U/mg of protein had shorter disease-free intervals (DFI) than those with higher values (p < 0.05). Abnormally high serum levels of MCA were found in 8% of patients with benign diseases, 4% of NED patients, 22% of Mo patients, and in 76% of MT cases. In primary breast cancer MCA values were related to tumor size and nodal involvement. A trend toward a lower DFI in patients with elevated presurgical MCA levels was observed but was of no statistical significance. These differences became statistically significant when patients were subdivided according to nodal status, with shorter DFI in those without nodal invasion (p < 0.05). In metastatic patients, changes in serum MCA were related to the tumor's response to treatment in 82% of cases. The highest MCA values were found in patients with liver or bone metastasis and the lowest values were found in those with locoregional recurrence. In conclusion, although MCA is not a specific tumor marker, it can be useful as a prognostic factor (tissue and serum) and in monitoring metastatic patients.

CYFRA 21-1 in lung cancer: comparison with CEA, CA 125, SCC and NSE serum levels.

CYFRA 21-1, CEA, CA 125, SCC and NSE serum levels were determined in 50 healthy subjects and in 189 patients with primary lung cancer (101 with locoregional disease, 68 with recurrence and 20 patients with no evidence of residual disease (NED). Abnormal CYFRA 21-1 serum levels were found in 53.6% (90/168) of the patients with active cancer. Neither healthy subjects nor NED patients had abnormal serum levels. CYFR alpha 21-1 serum concentrations were significantly higher in patients with active cancer than in healthy subjects or in NED patients (p < 0.0001). CYFRA 21-1 sensitivity was related to tumor histology with abnormal levels in 64.7% of patients with NSCLC and in 30% of patients with SCLC (P < 0.0001). In NSCLC, serum CYFRA 21-1 concentrations were also related to histological type, the highest values being found in squamous cell carcinomas and LCLC and the lowest in adenocarcinomas (p < 0.04). There was also a clear relationship between CYFRA 21-1 and tumor extension, with significantly higher values in patients with metastases than in those without metastases (p < 0.0001). Abnormal CEA values were found in 49.1%, CA 125 in 39%, SCC in 27.8% and NSE in 21.3% of the patients with active cancer.(ABSTRACT TRUNCATED AT 250 WORDS)

Dental caries prevalence and experience among the group of institutionalized hearing impaired individuals in Pondicherry--a descriptive study.

A descriptive study was conducted among a group of hearing-impaired individuals in Pondicherry to assess the dental caries prevalence and experience. A total 114 individuals were examined. The data was collected by direct clinical examination using appropriate indices and findings were recorded on the proforma sheets. The data were statistically processed and the results were obtained. Prevalence of dental caries in terms of DMFT is 42.98% and dft is 45%. Mean dft +/- s.d is 1.2 +/- 1.38 and Mean DMFT +/- s.d is 1.0 +/- 1.42. It was concluded that in both permanent and deciduous dentition and the females have high caries prevalence.

Disappearing bone disease: a case report and review of the literature.

Disappearing bone disease is a rare condition manifested by massive osteolysis. Its etiology is unknown. Histologically, involved bones show a nonmalignant proliferation of thin-walled vessels. The mechanism of bone absorption remains unclear. No treatment has proven effective in arresting the disease. Cases in which there is extraosseous involvement have a much poorer prognosis.
