Primary gastrointestinal non-Hodgkin's lymphoma. A population based study in central Finland in 1975-1993.

Gastrointestinal lymphomas have been uncommon, but the frequency of their predisposing conditions is increasing. The objective of the present study is to determine the frequency of gastrointestinal lymphomas in the area of central Finland as well as the influence of clinical features and therapeutical approaches on the survival of these patients. All samples of gastrointestinal non-Hodgkin's lymphomas diagnosed of patients living in the province of central Finland in 1975-1993 were re-examined. In central Finland the mean annual frequency of new gastrointestinal lymphomas was 10/1000000 in 1975-1984 and 16.0/1000000 in 1985-1993. The total incidence of gastrointestinal lymphomas in Finland adjusted for age to the world standard population was 12.5/1000000 in 1992. Two patients with peripheric T-cell lymphoma had a coeliac disease. Other predisposing conditions were not found. The stage of distribution of the lymphoma (p < 0.01) and radicality of the surgery (p < 0.01) were the most influencing factors on the survival of these patients. In conclusion the early distinction of gastrointestinal lymphomas is vital because of an increasing frequency of predisposing factors and a better prognosis due to new combination therapies.

Peripheral squamous odontogenic tumour.

Squamous odontogenic tumour (SOT) is a rare, benign epithelial tumour of odontogenic origin. A recurrent case of SOT with peripheral occurrence is described. In 1971, a tumour from the anterior maxillary palatal mucosa of an 11-year-old female was excised. In 1984, when the patient was 24 years old, a recurrent tumour was found in the same area. The histopathological appearance of the lesion, which was found to be identical with the primary tumour, was that of an SOT. Both the clinical and radiographic features supported the extra-osseous involvement of both tumours. The SOT is further evaluated and its origin is discussed.

Diagnosing mammary cancer among an unselected Finnish population. Proposal for practical improvements.

A total of 309 new mammary cancer patients were found in three successive years among 250,000 unselected Finns showing an annual rate of 1.08 cancers per 1000 women over 20 years of age. The main preoperative examinations were palpation and mammography. Palpation alone was performed preoperatively in 158 (51 percent) patients, palpation and mammography in 120 (38 percent), and the tumor was nonpalpable and found only in mammography in 31 (10 percent) patients. Fine-needle biopsy with palpation was performed in 191 (62 percent) patients and it confirmed definite malignancy in 89 cases, that is in 47 percent of the biopsied patients and in 29 percent of all patients. Mammography was most valuable in small tumors and fine-needle biopsy in large ones. The number of mammographies performed in the whole population per each new cancer case was 50; it seems unreasonable to increase the number of mammographies performed. It seems that the best way to improve the present preoperative evafuation of mammary cancer patients would be to perform a fine-needle biopsy under stereotactic guidance in every patient, and especially in those with a small tumor.
