To evaluate the significance of plasma free serotonin (5-hydroxytryptamine) and Ca15.3 for the early detection of breast cancer recurrence.
Free serotonin and Ca15.3 levels were measured by ...I-125-Serotonin RIA (DDV Diagnostica, Marburg, Germany) in plasma and an ELISA kit (Roche Diagnostic GmbH, Mannheim, Germany) in serum, respectively in women (N=29) who responded to primary treatment for breast cancer and who were followed-up for recurrence. For analysis, patients were sub-divided according to TNM staging into groups with localized (T1-2N0-M0) and advanced (T1-2N1-2M0-1) disease. The control group were healthy blood donors.
Patients with advanced disease had a significantly higher plasma serotonin level than those with localized disease or controls, whereas Ca15.3 levels remained in normal range in all groups. At the time of serotonin measurement, radiological findings were negative for all patients in the localized-disease group, but positive in nine patients in the advanced-disease group.
Plasma free serotonin may be used for the early detection of recurrent/metastatic breast cancer disease, but validation on a larger number of patients is needed.
Abstract Objectives Randomized trials involving aromatase inhibitors (AIs) in the adjuvant treatment of breast cancer patients have reported increased osteoporosis risk. Bone loss can be reduced with ...appropriate life style, vitamin D and calcium supplements, and with bisphosphonate therapy. The aim of this analysis was to investigate adherence to vitamin D and calcium in postmenopausal breast cancer patients receiving adjuvant non-steroidal AIs, and oncologists' adherence to the bone health guidelines. Material and methods This prospective study included 438 newly diagnosed patients and those who have already been receiving non-steroidal AIs for up to 3.5 years. Median endocrine therapy duration before recruitment in the study was 10.5 months (interquartile 4.8–26.6). Results Densitometry was performed on 142 patients (32.4%) before initiation of endocrine therapy, and on additional 38 (8.6%) patients at second study visit. Densitometry was not performed on 258 (59%) patients. Vitamin D and calcium were prescribed to 329/438 (75.1%) patients at some point during the study. Patients who took more than 80% of the prescribed dose were considered adherent. Self-reported adherence was 88.4%. Osteoporosis was diagnosed in 24 patients (5.5%) of the total study population, bearing in mind that 258/438 (59%) patients did not have densitometry. Bisphosphonates were prescribed to 54/438 (12.3%) patients, whilst only 19 (35.2%) of those had osteoporosis. Conclusion In this analysis, lack of oncologists' adherence to the bone health guidelines was observed. In addition, a significant proportion of the patients did not adhere to the vitamin D and calcium.
Breast cancer accounted for 28% of all new cancers and 18% of female cancer deaths in Europe in 2010. It is the most common type of cancer in women in Croatia, with an incidence rate of 56.9/100 000 ...in the year 2010, and the highest number of newly diagnosed women aged between 60 and 64. Multiple factors are associated with an increased risk of breast cancer: advancing age, family history, exposure to endogenous and exogenous reproductive hormones, dietary factors, benign breast disease, and environmental factors. To assess demographic and clinicopathologic features of primary breast cancer, we retrospectively analyzed 870 patients treated in our institution between 1997 and 2010. Data were obtained from medical documentation and a printed questionnaire regarding life habits. Most of our patients presented with a breast lump and were self-diagnosed by breast examination. This fact highlights the need of regular breast self-examination, although it should also be taken into account that most of our patients did not attend regular mammography screening (only 31%). One of the most concerning facts is that the mean time from observing the first symptom to visiting a physician was 4 months. Previous studies have identified ignorance, fear and fatalistic attitudes, poor socioeconomic conditions, and illiteracy as important factors resulting in delay. Considering these facts, education and raising awareness about the disease in the general population is one of the key weapons for lowering breast cancer mortality.
Due to progressive dyspnea, a male patient aged 59 underwent medical examination in 2003 in a local hospital. Neck ultrasound and fine-needle aspiration biopsy (FNAB) of a suspect lesion in the ...thyroid gland revealed the presence of a malignant neoplasm, i.e. mesenchymal tumor. Immunocytochemistry for epithelial membrane antigen, chromogranin A and leukocyte common antigen (CD45) was negative, while vimentin and S-100 were positive. The patient was referred to a university hospital center, where further oncologic work-up was done. Neck ultrasound revealed a tumor in the left lobe of the thyroid, with extension to the aortic arch. After repeated FNAB, cytologic diagnosis of primary thyroid fibrosarcoma was established. Due to the locally advanced and consequently inoperable disease, primary radiotherapy to the neck region (64 Gy in 32 fractions) was applied, followed by 6 cycles of chemotherapy with doxorubicin. After completion of therapy, computed tomography scan demonstrated significant regression of primary disease, but it was still not amenable to surgical treatment. Thus, the decision of the oncology board was active surveillance of the patient. During 9-year follow up, no signs of progression or activity of the disease were found.
Pancreatic cancer is a malignant neoplasm of the pancreas. It does not cause any symptoms in the early stage, and later symptoms are nonspecific, thus the disease is usually diagnosed when already ...advanced. In 2008, pancreatic cancer ranked eighth on the list of the 10 most common cancers among men in Croatia and tenth on the list of the most common cancers among Croatian women. Pancreatic cancer has a poor prognosis, with a survival time of only 6–8 months for metastatic disease. Gemcitabine is the standard chemotherapeutic option. Other chemotherapeutic agents include5-fluorouracil and leucovorin. In this paper, we present a case of a patient diagnosed with locally advanced and metastatic pancreatic cancer, who is still alive and currently receives his fourth line of chemotherapy 5 years after the diagnosis. Following disease progression on gemcitabine chemotherapy, he was treated with chemoradiotherapy which, however, had no effect. We then applied cisplatin monochemotherapy which offered excellent disease control, was well tolerated by the patient and, although somewhat obsolete in this form, showed to be a valuable chemotherapeutic option.
Splenic irradiation has long been known as a palliative treatment modality in patients with various malignant hematologic diseases aiming to ameliorate clinical symptoms of splenomegaly as well as ...clinical sequels of hypersplenism. It provides considerable effect with low toxicity although exact radiotherapy dose and fractionation schedule are not known. During the 1996-2010 period, eleven patients were treated at our institution with splenic irradiation. They received 16 courses of fractionated radiotherapy. There were six patients with non-Hodgkin's lymphoma, four with chronic lymphocytic leukemia, and one patient with myelofibrosis. The median of the dose received was 7 Gy, while the median of dose received per fraction was 1 Gy. Both parallel opposed anterior-posterior fields and tangential fields were used. Due to the clinical target volume shrinkage, the treatment field was reduced in 44% of courses. Of the courses initiated for symptom control, 71% resulted in effective palliation, whereas of the courses started to treat hematologic sequels of hypersplenism 50% produced desirable effects. The most common side effects included thrombocytopenia and anemia. Splenic irradiation provides effective and low-toxic palliation of symptoms but it is much less successful in treating hematologic disorders caused by hypersplenism.
