RESUMO

Nutritional status is recognized as an independent and modifiable risk factor of outcome in stem cell transplant. Our research aim was to evaluate the impact of body mass index (BMI) and serum albumin on the prevalence of adverse events and survival in autologous transplant in children. A retrospective study was conducted of autologous transplants performed between 2006 and 2017 in the Children's Hospital Zagreb, Croatia. Nutritional status was assessed at the times of diagnosis, procedure, and discharge using BMI (underweight, normal, obese) and serum albumin (grades 1-4). Adverse events (fever, gastrointestinal toxicity, electrolyte disturbances, dysglycemia) and outcome (3-year, relapse, mortality) were documented. Seventy-seven children (54.5% males, mean age 7.9 years) underwent autologous transplant, mostly for neuroblastoma. In terms of BMI and albumin, which showed significant positive correlation at diagnosis (p = 0.026) and transplant (p = 0.016), most participants were well nourished. Average post-transplant weight loss was 4%. Major toxicities were severe mucositis (72.7%) and hypophosphatemia (31.2%). Relapse and mortality rates were 35.1% and 42.9%, respectively. Hypokalemia (p = 0.041) and hypomagnesemia (p = 0.044) were more prevalent in the underweight group, while obese children experienced significantly less severe mucositis (p = 0.016) and hypophosphatemia (p = 0.038). There was no significant difference regarding outcome among children of different nutritional status, although undernourished children tended to have lower relapse and mortality rates. In conclusion, underweight children are significantly more prone to severe electrolyte disorders and mucositis, and although statistical significance was not reached, are more likely to survive.

RESUMO

The aim is to present data on the treatment and follow-up in a cohort of patients with pediatric thyroid cancer who underwent total thyroidectomy and received postoperative radioactive iodine (I-131) therapy. The study was conducted in a tertiary high-volume thyroid center, in pediatric patients with differentiated thyroid cancer who were consecutively treated during the 1965-2015 period. A total of 45 patients aged ≤18 years having undergone total thyroidectomy with or without selective neck dissection were included in the study. Decision on postoperative I-131 ablation was based on tumor characteristics, postoperative thyroglobulin level, preablative whole body scintigraphy, and/or neck ultrasound. Median age at diagnosis was 15 years. The presence of cervical lymph node metastases was significantly associated with papillary thyroid cancer, larger tumor size, involvement of two thyroid lobes, and multifocal disease. The presence of distant metastases was significantly associated with larger tumor size. None of the patients died during follow-up period, and the 5-year and 10-year overall survival rates were 100%. The 5-year and 10-year progression-free survival (PFS) rates were 87% and 73%, respectively. Male gender (p=0.046), age ≤15 years (p=0.029) and tumor size >15 mm (p=0.042) were significantly associated with inferior PFS. A significant positive trend of increase in the number of newly diagnosed patients was observed over time (p=0.011). Clinical management of pediatric thyroid cancer is challenging, especially in the light of increasing incidence in this population. Male patients younger than 15 years and with tumors of more than 15 mm in size require additional caution due to lower PFS observed.

RESUMO

Usage of complementary and alternative medicine (CAM) is steadily increasing over the last decades, gaining medical, economic and sociological importance. The aim of the present study was to assess the use of complementary and alternative therapies in cancer patients. A cross-sectional, descriptive survey design was used to collect data through an anonymous questionnaire. A total of 267 patients were included in the study. The prevalence of CAM use among cancer patients in this study was 60.3%. It was found that 61 heterogeneous CAM therapies were used, the most popular among patients being naturopathy/folk medicine. In multivariate logistic regression analysis, independent predictors of CAM use were high income, divorced status, female sex and younger age. In conclusion, considering the fact that a large proportion of patients used at least one CAM approach, we need to continue our efforts to improve the patient-oncologist communication in order to deliver most reliable information to patients and to better understand the possible standard medicine-CAM interactions. According to results of the latest studies, CAM therapies that help manage pain, nausea, fatigue, anxiety, and other symptoms should be integrated into the patient overall care.

RESUMO

Testicular tumors are the most common solid tumors in men between 15 and 34 years of age. The worldwide incidence of these tumors has doubled in the past 40 years. Germ cell tumors comprise 95% of malignant tumors arising in the testes and they are classified either as seminoma or nonseminoma. Testicular cancers have a high cure rates even in disseminated stage of the disease. The chemotherapy mostly contributed to these results but surgery is an inevitable part of successful treatment. In a significant number of these patients treatment algorithms with minimum side effects are designed with the intention to maintain same cure rates as previously used, more aggressive therapy. The following text presents the clinical guidelines in order to standardize the procedures and criteria for diagnosis, management, treatment and follow-up of patients with testicular cancer in Republic of Croatia.

RESUMO

Dermatomyositis is a rare disease characterised by inflammatory muscle affection and characteristic cutaneous changes. When occuring in a patient with cancer, dermatomyositis may indicate recurrence or progression and poor outcome. Herein, the treatment of metastatic breast cancer, metastatic pattern, characteristics of long-term survivors, and link between dermatomyositis and breast cancer are discussed and the literature reviewed. We report a 57-year old female patient with metastatic bilateral breast cancer whose ovarian and peritoneal relapse after long-term remission was disclosed by occurence of paraneoplastic dermatomyositis. The patient previously had a 15-year long disease free-period after primary treatment for breast cancer before onset of pulmonary dissemination. Following antracycline-based chemotherapy, the complete remission lasting another 15 years was accomplished. Dermatomyositis had been resolved upon induction of second-line taxane-based chemotherapy. After completion of six cycles of gemcitabine and paclitaxel chemotherapy, check-up revealed further progression. The patient subsequently underwent six cycles of third-line CAP chemotherapy (cyclofosfamide, doxorubicine, cisplatin) but disease progressed and oral capecitabine chemotherapy was initiated. The patient received four cycles of capecitabine followed by further vast progression and finally expired following massive pulmonary embolism. Our case stresses the need of thorough staging and check-up when dermatomyositis arises in patients with breast cancer, regardless of previous stable long-term complete remission. Furthermore, we believe that treatment with curative intent in young patients with metastatic breast cancer, who have good performance statuses and no comorbidities is required, because it is more likely to produce long-term complete remission. However, following disease relapse a poor outcome can be expected.

RESUMO

Quality of life (QoL) is an important outcome in assessment of breast cancer treatment. Data comparing QoL after different adjuvant treatments and QoL data on long-term survivors are modest. The aim of this study was to compare QoL scores of patients receiving adjuvant treatment with long-term breast cancer survivors, and to correlate QoL scores with clinical data. Sixty patients were recruited for the study: 20 during adjuvant radiotherapy, 20 during adjuvant chemotherapy, and 20 long-term breast cancer survivors. QoL was assessed using the self-administered EORTC core questionnaire QLQ-C30 and breast cancer-specific module QLQ-BR23. QoL scores between groups were compared using Kruskal-Wallis test and effects of clinical factors on QoL domains were tested using multiple regression analysis. No differences between three groups were observed in terms of all QoL scores. As measured by QLQ-C30, least affected QoL scales were cognitive functioning, social functioning, and physical functioning in all three patients group, while insomnia and pain scales were the most detrimentally affected. Among the groups, the highest scores of global health status and other functional scales were in adjuvant chemotherapy group. Measured by QLQ-BR23, body image scale was most affected, while sexual functioning scale was minimally affected, in all three groups. Multiple regression analysis has shown that the patient age were the only statistically significant predictor for global health status scale, and constipation scale. Our results demonstrated similar and favorable QoL in all three groups of patients and provided basic information on QoL in Croatian breast cancer patients.

RESUMO

Colorectal cancer is the third most common malignant tumour in males and the fourth most common malignancy in women in the Republic of Croatia. It is usually manifested as stool forming disorders, feeling that bowel does not empty completely, finding blood in the stool, weight loss and fatigue. In-time diagnosis, confirmed by pathohistological findings, is cornerstone of successful treatment. The decision about treatment is made based on clinical assessment of disease stage and other risk factors, after completion of the diagnostic process. Depending on that, treatment options include surgery, the application of systemic therapy (chemotherapy, immunotherapy) and radiotherapy. The following text presents the clinical guidelines in order to standardize procedures and criteria for the diagnosis, management, treatment and monitoring of patients with colorectal cancer in the Republic of Croatia.

RESUMO

Intraluminal high dose rate brachytherapy (ILHDR BT) is one of several effective modalities for palliation of advanced esophageal cancer. Thirty patients with endoscopic-proven, mostly locally advanced, squamous cell carcinoma of the esophagus, not involving the gastroesophageal junction and without distant metastases, were included in this analysis. Twenty-nine patients received two ILHDR BT sessions of 8 Gy within a week and one patient received only one session. All patients were followed monthly. Outcomes included quality of life (QOL), symptoms control: dysphagia, regurgitation, odynophagia, and chest or back pain, as well as, overall survival. Through 4 months of follow-up, QOL was statistically improved (having lowered scores) in regards to feelings (P= 0.013), sleeping (P= 0.032), eating (P= 0.020), and social life (P= 0.002). The most significantly improved symptom was dysphagia (P < 0.006), with a reduction of 0.52 units or one-half grade. Regurgitation, odynophagia, and pain were lower during follow-up but were not statistically significant. The median overall survival from death of any cause was 165 days (with a 95% confidence interval of 128-195 days). In conclusion, ILHDR BT of advanced squamous esophageal cancer consisting of two out-patient procedures is very successful in achieving the primary objectives of the patients to reduce dysphagia and improve QOL.

RESUMO

Paget's disease of the breast is a rare form of breast cancer and represents only 1% to 4% of all breast cancers. It is characterized by the presence of Paget's cells in the epithelium tissue (in epidermis) and it manifests as a lesion of the nipple. In most cases, Paget's disease is associated with an underlying breast malignancy. Mastectomy has been considered the treatment of choice, but breast conservation is also being explored, in properly selected patients, depending on the underlying malignancy. We report a case of Paget's disease occurring in the contralateral breast 11 years after mastectomy for invasive ductal carcinoma but with no underlying breast malignancy.

RESUMO

Approximately 70-80% of all cancer patients receiving chemotherapy experience nausea and/or vomiting. Nausea and vomiting are important side effects of cancer treatment, which can significantly affect a patient's quality of life, leading to poor compliance with further chemotherapy treatment. The main principle of emesis control is prevention. Currently available antiemetic agents corticosteroids, 5-hydroxytriptamine receptor antagonists, and neurokinin-1 antagonists, are used alone or in combination. Antiemetic regimen should be chosen based on the emetogenic potential of the chemotherapy regimen, previous experience with antiemetics, and patient-specific risk factors. Newer agents, including second generation 5-HT3 receptor antagonist palonosetron and the NK-1 antagonist aprepitant, offer additional clinical benefit in highly and moderately emetogenic therapy, especially in delayed nausea and vomiting. The aim of this Guidelines is to achieve same standards of care in the treatment of nausea and vomiting across Croatia that are applicable in our environment--only available drugs are included in the Guidelines.

RESUMO

There is a great interest in molecular markers that would help in the preoperative diagnosis of malignant thyroid nodules in cases of indeterminate fine-needle aspiration cytology. The aim of this study was to determine the diagnostic accuracy of HMGA2 gene expression in discriminating benign from malignant thyroid nodules. In this study, 237 preoperative thyroid fine-needle aspiration samples were analyzed prospectively for the expression of the HMGA2 gene by real-time reverse transcription polymerase chain reaction. The results were evaluated against the postoperative histopathologic diagnosis or definitive cytologic diagnosis in cases of nodular goiter and Hashimoto thyroiditis. Among 237 samples from patients with thyroid nodules that were analyzed, 231 were adequate for real-time reverse transcription polymerase chain reaction analysis. With a cutoff value of 8.71 for relative gene expression, HMGA2 was positive in 19 (16.4%) of 116 nodular goiter, 1 (2.6%) of 39 Hashimoto thyroiditis, 9 (28.1%) of 32 follicular adenoma, 0 (0%) of 5 Hurthle cell adenoma, 32 (88.9%) of 36 papillary carcinoma, and 3 (100%) of 3 follicular carcinoma samples. In discriminating between malignant and benign thyroid nodules, HMGA2 has shown specificity of 84.5%, sensitivity of 91.9%, positive predictive value of 53.1%, and negative predictive value of 98.2%. High sensitivity and negative predictive value of HMGA2 for preoperative detection of malignant thyroid nodules shown in this study indicate that it may have a role as an ancillary marker in cytology in the management of patients with thyroid nodules.

RESUMO

Bone morphogenetic protein 6 (BMP6) has unique properties regarding structure and function in supporting bone formation during development and adult life. Despite its known role in various malignant tumors, the prognostic significance of BMP6 expression in oral squamous cell carcinoma (OSCC) remains unknown. The aim of the study was to investigate immunohistochemical expression of BMP6 in OSCC in correlation with clinical and pathological parameters, disease recurrence and survival. In addition, we investigated other parameters in order to identify prognosticators of neck metastases and final outcome. The study included 120 patients with clinically T1-3N0 OSCC who were primarily surgically treated between 2003 and 2008. There were 99 (82.5%) male and 21 (17.5%) female patients. The five-year disease-specific survival for the whole cohort was 79.7%. Tumors smaller than 2 cm in diameter showed higher incidence of strong BMP6 expression. No statistical correlation was observed between other clinico-pathological factors and BMP6 expression. Expression of BMP6 was not associated with disease recurrence and survival. BMP6 may not serve as prognosticator of final outcome or recurrence in clinically node-negative OSCC subjects. In multivariate analysis predictors of poorer survival were positive surgical margin, moderate tumor cell differentiation and pathological involvement of levels IV and/or V.

RESUMO

BACKGROUND: The purpose of this study was to detect parameters that could serve as predictors of radioactive iodine (I-131) ablation failure in patients with low-risk and intermediate-risk differentiated thyroid carcinoma (DTC). METHODS: Our cohort study included 740 patients with DTC who received postoperative I-131 remnant ablation. Anthropometric, biochemical, and pathohistological parameters were analyzed and correlated with ablation outcome using multivariable logistic regression models. RESULTS: Treatment failure rates were higher in patients <53 years, with N1a classification, and lymph node capsular invasion. In patients with N1a disease, thyroglobulin (Tg) > 2.4 ng/mL predicted treatment failure with 93.8% sensitivity and 52.5% specificity, and in patients with N1b disease, Tg > 14.9 ng/mL with 77.8% sensitivity and 92.9% specificity. I-131 activity was not associated with treatment outcome. CONCLUSION: Patients < 53 years old, with higher Tg levels, N1a classification, and lymph node capsular invasion have a higher risk of ablation failure. Stimulated Tg is an excellent predictor of treatment failure in patients with N1 disease. © 2016 Wiley Periodicals, Inc. Head Neck 39: 109-115, 2017.

RESUMO

Syphilis is a sexually transmitted, systemic disease caused by the spirochete bacterium Treponema pallidum. The most common mechanism of transmission is sexual intercourse. Although there are several hypotheses, the exact origin of the disease remains unknown. Newly published evidence suggests that the hypothesis supporting the theory of the American origin of the disease is the valid one. Among 1500 analyzed pathographies of composers and musicians, data on ten Anglo-American composers and jazz musicians having suffered from neurosyphilis (tertiary stage of the disease) were extracted for this report. In this group of Anglo-American composers and musicians, most of them died from progressive paralysis while still in the creative phase of life. Additionally, diagnoses of eleven other famous neurosyphilitic composers, as well as basic biographic data on ten less known composers that died from neurosyphilis-progressive paralysis are also briefly mentioned. In conclusion, neurosyphilis can cause serious neurological damage, as well as permanent disability or death, preventing further work and skill improvement.

RESUMO

PURPOSE: : colorectal cancer (CRC) is the third most commonly diagnosed cancer worldwide, and detection of new prognostic markers is mandatory for patients to receive optimal oncological treatment. The aim of the study was to assess clinical and prognostic value of red cell distribution width (RDW) in patients with CRC. METHODS: : RDW values in 90 patients with CRC undergoing surgery for primary disease were analyzed in pre- and postoperative setting, and correlated with clinical and hematological parameters. RESULTS: : Both pre- and postoperative RDW measurements were found to be associated with features of iron deficiency anemia, inflammatory response to tumor, advanced age and depth of tumor invasion. Optimal cutoff points were calculated to be 14% for preoperative and 13.6% for postoperative RDW measurements. Elevations in both pre- and postoperative RDW values had significant effects on survival in univariate and multivariate analyses. Effects were found to be independent of tumor related features, stage of the disease, development of anemia and aberrant inflammatory response to tumor. CONCLUSIONS: : RDW is an integrative parameter reflecting tumor specific features and shows significant association with overall survival in patients with CRC. This is especially important in patients with stage 2 disease where elevation in preoperative RDW values can contribute to recognition of higher risk patients.

RESUMO

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.

RESUMO

The aim of this study was to evaluate the efficacy of different radioactive iodine (I-131) activities used for re-ablation, to compare various combinations of treatment activities, and to identify predictors of re-ablation failure in low- and intermediate-risk differentiated thyroid carcinoma (DTC) patients. The study included 128 consecutive low- and intermediate-risk patients with DTC with ablation failure after total thyroidectomy. Patient characteristics, T status, tumor size, lymph node involvement, postoperative remnant size on whole-body scintigraphy, serum thyroglobulin (Tg), thyroid-stimulating hormone (TSH), anti-Tg antibody (TgAb), and Tg/TSH ratio were analyzed as potential predictors of the re-ablation success. Re-ablation was successful in 113 out of 128 patients (88.3 %). Mean first I-131 activity was 2868 ± 914 MBq (77.5 ± 24.7 mCi) and mean second I-131 activity 3004 ± 699 MBq (81.2 ± 18.9 mCi). There was no association between the first, second, and cumulative activity with re-ablation treatment outcome. Treatment failure was associated with higher Tg levels prior to re-ablation (Tg2) (OR 1.16, 95 % CI 1.05-1.29, P = 0.003) and N1a status (OR 3.89, 95 % CI 1.13-13.41, P = 0.032). After excluding patients with positive-to-negative TgAb conversion, Tg2 level of 3.7 ng/mL predicted treatment failure with a sensitivity of 75.0 %, specificity of 80.5 %, and a negative predictive value of 97.1 %. Patients with positive-to-negative TgAb conversion had higher failure rates (OR 2.96, 95 % CI 0.94-9.29). Re-ablation success was high in all subgroups of patients and I-131 activity did not influence treatment outcome. Tg may serve as a good predictor of re-ablation failure. Patients with positive-to-negative TgAb conversion represent a specific group, in whom Tg level should not be used as a predictive marker of treatment outcome.

RESUMO

BACKGROUND/AIM: Protein connexin 43 (Cx43), a part of intercellular gap junctions, is frequently down-regulated in tumors. The aim of the study was to compare Cx43 expression in primary colorectal tumors of patients with stage III and IV disease. PATIENTS AND METHODS: Immunohistochemical expression of Cx43 was analyzed in 50 colorectal adenocarcinomas from surgically-treated patients of stage pT3N1-2 without metastases (M0) and 50 specimens of the same pTN stage from patients with synchronous liver metastases (M1). Association of Cx43 expression with clinicopathological factors and tumor site was also analyzed. RESULTS: There was no significant difference in Cx43 expression between M0 and M1 tumor specimens (p=0.817), as well as in Cx43 expression between colonic and rectal tumors (p=0.116), respectively. Stromal expression of Cx43 was higher in M1 than in M0 tumors (p=0.004). CONCLUSION: Stromal Cx43 expression is possible indicator of metastatic potential of colorectal adenocarcinoma.

RESUMO

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.

RESUMO

Metastases to pituitary gland are unusual and mostly asymptomatic, presenting with local symptoms in one of ten patients, and only 3%-5% of them are of prostate origin. Here we report and evaluate the effectiveness and safety of multimodal treatment in a patient with pituitary metastasis of a prostate foamy gland carcinoma. A 78-year-old male patient presented with blurred vision and headache without a previous history of malignancy. Magnetic resonance imaging scans revealed a large sellar mass, with infiltration of the surrounding structures. Maximal transsphenoidal reduction of pituitary metastasis was performed, with a histologic finding of metastatic prostate foamy gland adenocarcinoma. Evaluation of the prostate specific antigen revealed a very high level (1461 ng/mL) and foamy gland carcinoma was found on prostate needle biopsy. The patient received 3D conformal external beam radiotherapy with 6 MV photons to the sellar and parasellar region with a tumor dose of 44 Gy, followed by androgen deprivation therapy. Follow up magnetic resonance imaging done after radiotherapy showed shrinkage of the tumor process, with rapid prostate specific antigen decline to 0.3 ng/mL. The visual function was fully established and headache resolved. On the last follow up 14 months after the diagnosis, the patient was alive and free from clinical signs of disease. Tailored treatment, including limited radiotherapy in a higher palliative dose, in a patient with foamy gland symptomatic pituitary metastatic disease resulted in good local and systemic control of the disease. In older male patients with clinical and/or radiologic characteristics suggestive of metastatic pituitary disease, the prostate specific antigen test should be included as part of the work-up.
