Objective: To discuss the prognostic factors and outcomes of treatment in patients diagnosed with papillary thyroid microcarcinoma. Design: Retrospective observational case review. Setting: Department of Otorhinolaryngology of the tertiary referral teaching hospital of Parma. Participants: Ninety-seven patients diagnosed with PTMC and surgically treated between January 1998 and December 2007. Main outcome measures: Clinical and histopathological characteristics of the study group were identified and statistically analysed. Results: No cancer-related deaths were registered. Incidence of recurrent disease was 9% after a 43 month mean follow-up (range 12-120). Univariate analysis detected that metastases in neck lymph nodes at diagnosis (p = 0.025), a tumour >5 mm in size (p = 0.011), the presence of bilateral tumoural foci (p = 0.007), the presence of capsular invasion (p = 0.001), and the presence of vascular invasion (p = 0.004) were related to recurrent disease. On multi-variate analysis, the presence of bilateral tumoural foci (p = 0.030), and the presence of capsular invasion (p = 0.005) were significantly related to tumour recurrence.

Thymidine kinase (TK1) is an enzyme involved in DNA synthesis that leaks into the blood as a result of high cell turnover, particularly in the case of cancer. Serum TK1 activity has been used for prognosis and monitoring of leukemia and lymphoma patients for many years. Here, we describe the first clinical results with the newly developed TK 210 ELISA from AroCell AB. Sera from 124 breast cancer patients with known TNM classification along with sera from 53 healthy females were analyzed by TK 210 ELISA for TK1 protein and TK1 activity levels by the 3[H]-deoxythymidine (dThd) phosphorylation assay. The limit of detection for the TK 210 ELISA was 0.17 ng/ml, and 60 % of the sera from female blood donors were below this value. The median TK1 levels found in sera from breast cancer patients with T1 to T4 stage disease were 0.31, 0.46, 0.47, and 0.55 ng/ml, and these levels significantly differed from healthy controls. The median values of the biomarker CA 15-3 were also increased in patient sera from T1 to T4 patients (16, 34, 36, 40 U/ml, respectively). TK 210 ELISA showed significantly higher sensitivity for the T1 and T2 breast cancer patients compared to the TK activity assay. The combination of the TK1 ELISA and CA 15-3 biomarkers demonstrated a significant increase in sensitivity up to 15 % compared to each marker alone. This evaluation of the TK 210 ELISA strongly suggests that it can provide independent and complementary information for patients with breast cancer.Electronic supplementary materialThe online version of this article (doi:10.1007/s13277-016-5024-z) contains supplementary material, which is available to authorized users.

Hürthle cell papillary thyroid carcinoma (HCPTC) has been studied separately from other types of thyroid carcinoma in relatively few studies. The aim of our study was to determine the factors associated with the survival of patients with HCPTC in Slovenia, an iodine-deficient region. A total of 1552 patients with thyroid carcinoma were seen at our institute during the period of 1976-2003; of them, 42 patients (33 females, 9 males; age 10-85 years, median 56.5 years) had histopathologically verified HCPTC. The data on the patients' gender, age, disease history, extent of disease, morphologic characteristics, therapy, locoregional control, disease-free interval, and survival were collected. The statistical correlation between possible prognostic factors and the disease-free interval and survival was analyzed by chi2 test and log rank analysis. The tumor diameter ranged from 1 to 9 cm (median, 3 cm). Extrathyroid tumor growth was found in 19 patients, lymph node metastases in 13 patients, and distant metastases in 2 patients. Primary treatment consisted of total or near-total thyroidectomy (39 patients), lobectomy (2 patients), radioiodine ablation of the thyroid remnant (37 patients), external irradiation (14 patients), and chemotherapy (3 patients). Locoregional recurrence was diagnosed in four patients, and dissemination in 1 patient during the follow-up period of 0.75-20 years (median, 5.5 years). Three patients died of thyroid carcinoma during the follow-up period. The 5-year and 10-year survivals were 94% and 87%, respectively. The 5-year and 10-year disease-free intervals were 93% and 81%, respectively. The factors correlated with the survival were: age, extrathyroid tumor growth, primary tumor stage, and regional and distant metastases. Although extrathyroidal tumor growth was found in 45% of the patients with HCPTC, our patients had a favorable prognosis. Long-term survival and locoregional control of disease are likely after the radical tumor resection, radioiodine ablation of the thyroid remnant, and external irradiation.

BackgroundThe purpose of the study was to evaluate the ability of ultrasound (US) and fine needle aspiration biopsy (FNAB) in reducing the number of melanoma patients requiring a sentinel node biopsy (SNB); to compare the amount of metastatic disease in regional lymph nodes in SNB candidates with clinically uninvolved lymph nodes and of those with US uninvolved lymph nodes; and to compare the overall survival (OS) of both groups.MethodsBetween 2000 and 2007, a SNB was successfully performed in 707 patients with melanoma. The preoperative US of the regional lymph node basins was performed in 405 SNB candidates. In 14 of these patients, the US-guided FNAB was positive and they proceeded directly to lymph node dissection. In 391 patients, the preoperative US was either negative (343 patients) or suspicious (48 patients) (US group). In the remaining 316 patients the preoperative US was not performed (non-US group).ResultsThe proportion of macrometastatic sentinel lymph nodes (SN), number of metastatic lymph nodes per patient and proportion of nonsentinel lymph node metastases were found to be lower in the US group compared to the non-US group. The smaller tumour burden of the US group was reflected in a significantly better OS of patients with SN metastases.ConclusionsThe preoperative US of regional lymph nodes spares some patients with melanoma from undergoing a SNB. Patients with regional metastases and a negative preoperative US have a significantly lower tumour burden in comparison to those with clinically negative lymph nodes, which is also reflected in a better OS.

BackgroundPrimary treatment of patients with advanced epithelial ovarian cancer consists of chemotherapy either before (neoadjuvant chemotherapy, NACT) or after primary surgery (adjuvant chemotherapy). The goal of primary treatment is no residual disease after surgery (R0 resection) what is associated with an improvement in survival of patients. There is, however, no evidence of survival benefits in patients with R0 resections after prior NACT.MethodsWe retrospectively reviewed the records of patients who were treated with diagnosis of epithelial ovarian cancer at Institute of Oncology Ljubljana in the years 2005–2007. The differences in the rates of R0 resections, progression free survival (PFS), overall survival (OS) and in five-year and eight-year survival rates between patients treated with NACT and patients who had primary surgery were compared.ResultsOverall 160 patients had stage IIIC epithelial ovarian cancer. Eighty patients had NACT and eighty patients had primary surgery. Patients in NACT group had higher rates of R0 resection (42% vs. 20%; p = 0.011) than patients after primary surgery. PFS was 14.1 months in NACT group and 17.7 months after primary surgery (p = 0.213). OS was 24.8 months in NACT group and 31.6 months after primary surgery (p = 0.012). In patients with R0 resections five-year and eight-year survival rates were 20.6% and 17.6% in NACT group compared to 62.5% and 62.5% after primary surgery (p < 0.0001), respectively.ConclusionsDespite higher rates of R0 resections achieved by NACT, survival of patients treated with NACT was inferior to survival of patients who underwent primary surgery. NACT should only be offered to patients with advanced epithelial cancer who are not candidates for primary surgery.
