Based on our previous demonstration that elevated cyclooxygenase-2 (COX-2) expression is a prognostic factor for reduced survival in patients with adenocarcinoma of the esophagus, the aim of our study was to analyze the role of COX-2 expression in esophageal squamous cell carcinoma. We analyzed COX-2 protein expression from 117 consecutive patients by immunohistochemistry using a COX-2 specific monoclonal antibody. Eighty-one patients had not received any therapy before surgery whereas 36 patients received neoadjuvant chemotherapy as part of a randomized controlled trial.

Expression of cyclooxygenase-2 (COX-2) and matrix metalloproteinase-2 (MMP-2) associates with reduced survival in human breast cancer. COX-2 may be directly involved with mammary carcinogenesis, since expression of COX-2 is sufficient for formation of breast tumors in transgenic mice, and COX-2 selective inhibitors can suppress tumorigenesis in rodent models of breast cancer. MMP-2 is an extracellular matrix degrading proteolytic enzyme that bas been linked to invasion and metastasis.

The need for total thyroidectomy and extended for lymphadenectomy and the need for postoperative radioiodine ablation in the treatment of papillary thyroid carcinoma is continuously debated. Since less aggressive treatment in low-risk patients has been suggested, several scoring systems have been developed to identify low-risk patients. In the current study, we compared the AMES, MACIS and TNM staging systems in predicting carcinoma-specific mortality in papillary thyroid carcinoma.

Background: Adenocarcinomas of the gastric cardia and distal oesophagus are at present often considered as one clinical entity because of their comparable increasing incidence, prognosis, and optimal treatment options. However, it is still a matter of debate whether these malignancies have the same pathogenesis and genotype.

Aims: The aim of this study was to analyse expression of cyclooxygenase 2 (COX-2) in cardia carcinomas, and correlate this expression with clinicopathological parameters and survival.

Cyclooxygenase-2 (COX-2) expression has been shown to associate with poor prognosis in ovarian cancer, and an mRNA stability protein HuR has been shown to enhance expression of COX-2 in tissue culture conditions. We found cytoplasmic immunoreactivity for HuR protein in 52% (233 of 445) of serous-type ovarian carcinoma specimens, and it associated with high COX-2 expression (P = 0.0045) and with clinicopathological variables, including poor prognosis (P < 0.

Epidemiological studies have shown that the use of nonsteroid anti-inflammatory drugs (NSAIDs) is associated with reduced risk of gastric cancer. The best-known target of NSAIDs is the cyclooxygenase (Cox) enzyme. Two Cox genes have been cloned, of which Cox-2 has been connected with gastric carcinogenesis.

Gastrointestinal carcinomas synthesize elevated levels of prostaglandin E(2) (PGE(2)), which has been mechanistically linked to carcinogenesis. Recently, microsomal prostaglandin E synthase-1 (mPGES-1) was cloned, which seems to be inducible and linked to cyclooxygenase-2 (Cox-2) in the biosynthesis of PGE(2). We examined expression of mPGES-1 in intestinal type gastric adenocarcinomas and in gastric cancer cell lines.

Background & Aims: Use of nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with a reduced risk of cancer in the digestive tract. Cyclooxygenase (COX) is the best-known target of NSAIDs, and expression of the COX-2 isoform is elevated in esophageal carcinomas but its clinical significance remains unclear. We examined COX-2 expression in esophageal adenocarcinomas and its relation to clinicopathologic parameters.

Cyclooxygenase-2 (Cox-2) expression can induce mammary tumorigenesis in transgenic mice, and selective Cox-2 inhibitors are both chemopreventive and chemotherapeutic in rat models of breast cancer. We analyzed the expression of Cox-2 protein by immunohistochemistry in tissue array specimens of 1576 invasive breast cancers. Moderate to strong (elevated) expression of Cox-2 protein was observed in 37.

Background And Aims: Thyroidectomy and radical cervical lymph node dissection have been suggested as primary and secondary operations aimed at achieving biochemical cure in cases of medullary thyroid carcinoma (MTC). The purpose of this study was to find out behaviour of MTC in long-term follow-up, and to estimate possible difference in biological virulence between sporadic MTC and MTC in MEN2A.

Material And Methods: From 1967 through 1994, 39 patients with MTC, including 9 patients with hereditary disease, were operated on at the Second Department of Surgery, Helsinki University Central Hospital.

Most adrenal incidentalomas are nonfunctioning cortical adenomas that do not require surgery. Operative treatment is indicated if the incidentaloma has malignant features as seen during the radiologic workup, is hormonally active, or grows during follow-up. A conservative attitude is justified in asymptomatic patients if we know that the natural course of these tumors is not disadvantageous.

Anaplastic thyroid carcinoma is a rare, highly malignant tumor of elderly people. The purpose of this retrospective study was to characterize the patient population and to detect a potential subgroup with better prognosis or any intervention that would be useful. From 1967 through 1994 a total of 33 anaplastic thyroid carcinomas were operated on at the Second Department of Surgery, Helsinki University Central Hospital.

Background And Aims: Although only a small minority of thyroid nodules are malignant, a large proportion of operations are performed to exclude malignancy. The purpose of this study was to evaluate the role of preoperative ultrasound-guided fine-needle aspiration biopsy (FNAB) and intraoperative frozen section examination (FS) in the management of thyroid cancer.

Material And Methods: A retrospective study of 664 consecutive patients operated on for thyroid cancer from 1966 through 1994 at the Meilahti Hospital was performed.

Primary aldosteronism consists of a mixture of subgroups. The operative treatment is successful only in cases of aldosterone-producing neoplasia (and in rare cases of primary unilateral hyperplasia); all other cases should be treated medically. The aim of this study was to determine if aldosterone-producing neoplasia had been successfully differentiated from the other subgroups and the outcome of operative treatment.

Endocrine surgery is an important branch of modern surgery, and includes surgery of the thyroid and parathyroid as well as operative treatment of endocrine tumours in the adrenals, pancreas and the alimentary tract. Close cooperation between endocrine surgeons, medical endocrinologists, pathologists and radiologists is a prerequisite. The development of endocrine surgery has a long tradition in the Scandinavian countries, characterised by cooperation both in surgical training and research.
