Decreased staging of differentiated thyroid cancer in patients with chronic lymphocytic thyroiditis.

PURPOSE: The biological association between chronic lymphocytic thyroiditis (CLT) and differentiated thyroid cancer (DTC) has not been elucidated yet. The aim of the study was to assess whether the presence of CLT exerts any influence on clinical or histological presentation of DTC. METHODS: Nine hundred and seven consecutive patients with DTC treated in the years 1998-2016 were divided into two groups according to the presence or absence of concomitant CLT. The statistical differences were analysed. RESULTS: Out of 907 patients included in the study, 331 were diagnosed with DTC and CLT (studied group), while 576 patients with DTC but without CLT constituted a control group. The distribution of papillary and follicular thyroid cancer did not differ. In CLT group, the prevalence of pT1 was greater than for pT2-pT4 DTC (P = 0.0003; OR = 1.69, 95% CI 1.27-2.24) compared to controls (68.3 vs. 56.1%, respectively). The presence of multifocal lesions was similar. The thyroid capsule infiltration without extrathyroidal invasion (P < 0.0001; OR = 0.21, 95% CI 0.14-0.31) was more frequent in the studied group, unlike extracapsular invasion, which was significantly more often present in patients with DTC but without CLT (P = 0.004; OR = 1.66; 95% CI 1.17-2.34) as well as nodal involvement (P = 0.048; OR = 0.65, 95% CI 0.42-0.99). CONCLUSIONS: The collected data indicate a protective role of CLT in preventing the spread of the DTC. The presence of CLT might limit tumour growth to the primary site.

[Interdigestive gallbladder volume and and meal-induced gallbladder emptying in patients with diabetes]. / Miedzyposilkowa objetosc pecherzyka zólciowego oraz jego opróznianie po bodzcu pokarmowym u chorych na cukrzyce.

The aim of the study was to find whether the type of diabetes and the duration of this disease causes any influence on gallbladder (GB) emptying, after exclusion of possible effect of obesity and a hyperglycaemia over 7 mmol/l (126 mg%) on this phenomenon. The investigations were carried out in 44 subjects with diabetes mellitus, among them 22 with type I and 22 with type II. These groups were divided according to disease duration: shorter or longer than 3 years. Two control groups (CI, CII) comprised each 20 healthy subjects. The age of CI and CII corresponded to the age of diabetes groups type I and II, respectively. All subgroups as well as the control groups were matched according to sex percentage structure, body mass index (BMI) and body surface (BS). In groups with type I and II diabetes, the number of cases with diabetic neuropathy was comparable. There was not found any significant (p > 0.05) influence of diabetes on the interdigestive GB volume, neither non-standardized nor standardized with regard to standard BS (1.73 m2). In comparison to the control groups, after a test meal, there was in all diabetic groups a statistically significant (0.001 > p < 0.05) reduction of GB emptying observed. This diminution was most expressed in the group with long-lasting type I diabetes.
