RESUMO

AIMS: The aim of this study was to examine the substance-use history of young people in a rehabilitation center in Berlin with a therapeutic community structure, their thoughts about the rehabilitation process, and the evaluations of the center's employees. METHODS: The study used interviews with the young people in the rehabilitation process and the professionals working in the institution as well as observation studies over a period of three-months. A total of 23 people participated in the study, including 13 young people in the rehabilitation process with a history of substance use and 10 professionals working at the institution. The researchers used a qualitative research method along with a three-month observation study. RESULTS: After the interviews, 4 main themes and 5 sub-themes were identified among the young people with a substance-use history, and 4 main themes and 4 sub-themes were identified for the employees. CONCLUSION: It was determined that a well-structured rehabilitation center has positive psychological, social, cognitive, and behavioral effects on young people with a history of substance use.

RESUMO

Essentials Pharmacodynamic response to antiplatelet medication is heterogeneous. Platelet reactivity to dual antiplatelet therapy was analyzed by three platelet function assays. The prevalence of high and low platelet reactivity differed significantly between assays. Future trials are needed to determine the best assay to analyze platelet function. SUMMARY: Background High on-treatment platelet reactivity (HTPR) to antiplatelet medication leads to ischemic events, whereas low on-treatment platelet reactivity (LTPR) increases bleeding risk. However, various trials have failed to demonstrate superiority of tailored antiplatelet regimens (ARCTIC, ANTARCTIC, Trigger-PCI, and GRAVITAS). TROPICAL-ACS was the first study that demonstrated the benefit of tailoring antiplatelet medication according to platelet function analysis. A potential reason may be that different platelet function assays were used in these trials. Objectives To evaluate whether the results of platelet function tests are comparable. Patients/Methods We tested three commonly used assays - light transmission aggregometry (LTA), (Multiplate impedance aggregometry [MP]), and vasodilator-stimulated phosphoprotein phosphorylation assay (VASP) - in 23 patients receiving dual antiplatelet therapy with aspirin and clopidogrel. Results With LTA, HTPR occurred in 57% of patients; with VASP, it occurred in 43% of patients; and with MP, it occurred in 13% of patients. According to LTA, only 35% of patients were in the therapeutic window; according to VASP, 57% of patients were in the therapeutic window; and according to MP, 48% of patients were in the therapeutic window. With LTA, LTPR occurred in 9% of patients; with VASP, it occurred in 0% of patients; and with MP, it occurred in 39% of patients. Therefore, the prevalences of HTPR and LTPR differed significantly between assays. Remarkably, in 17% of patients, one assay showed HTPR whereas another showed LTPR. Conclusions The results of different platelet function assays differ substantially. Up to now, only TROPICAL-ACS had demonstrated a benefit of tailoring antiplatelet medication according to platelet function analysis. Future trials are needed to evaluate whether the platelet function assay used in TROPICAL-ACS is the 'correct' one and revives platelet function testing.

RESUMO

BACKGROUND: Data on CA-125 as a predictor of disease progression (PD) in ovarian cancer come predominantly from patients with platinum-sensitive disease receiving chemotherapy alone. We assessed concordance between CA-125-defined and RECIST-defined PD using data from the Gynecologic Cancer InterGroup (GCIG) randomized phase III AURELIA trial in platinum-resistant ovarian cancer (PROC). PATIENTS AND METHODS: Patients with PROC were randomized to receive single-agent chemotherapy with or without bevacizumab. PD by CA-125 was defined according to GCIG criteria (except that confirmatory CA-125 measurement was not required). This exploratory analysis included patients with RECIST PD and a CA-125 reading ≤28 days before and ≤21 days after RECIST-defined PD. RESULTS: Of 218 eligible patients, only 94 (43%, 95% confidence interval 36% to 50%) had concordant RECIST and CA-125 PD status (42% in the chemotherapy-alone arm; 45% in the bevacizumab combination arm, P = 0.6). There was no evidence of CA-125-defined PD in the remaining 124 patients despite PD according to imaging. There were no significant differences in baseline characteristics between patients with PD defined by both RECIST and CA-125 and those with RECIST-only PD. CA-125 was even less sensitive in detecting PD in patients with early (<8 weeks after randomization) compared with later RECIST-defined PD (69% versus 53%, respectively, not meeting CA-125 criteria; P = 0.053). There was no significant difference in survival after PD in patients with concordant PD by RECIST and CA-125 versus those with PD only by RECIST. We validated our findings in an independent study population of PROC. CONCLUSIONS: In this platinum-resistant population, PD was typically detected earlier by imaging than by CA-125, irrespective of bevacizumab treatment. Disease status by CA-125 at the time of PD was not prognostic for overall survival. Regular radiologic assessment as well as symptom benefit assessment should be considered during PROC follow-up.

RESUMO

Uterine clear cell carcinoma (UCC) is an aggressive variant of endometrial cancer. Comprehensive surgical staging is strongly recommended for these patients as an upstaging to Stage 3-4 occur in 35-50% of patients. Stage 1A (no myometrial invasion) according to FIGO 1988 staging system are seen very rarely in patients. In most of the studies, regarding adjuvant treatment, clear cell carcinoma were all evaluated with papillary serous carcinoma (PSC). Studies on clear cell histology are low in number and also a limited number of patients were included. Proportion of patients with complete surgical staging, number of lymph nodes excised, and rate of omentectomy were all heterogenous and were not presented uniformly in studies. There is no concensus regarding adjuvant treatment for Stage 1A patients. Some authors suggest only close observation. Vaginal brachytherapy is also strongly recommended in some studies of this review. Multi-institutional studies with homogenous patient characteristics with homogeneous surgery is warranted.

RESUMO

AIM: Aim of the study was to assess bone metabolism disturbances in children with acute lymphoblastic leukemia following cessation of chemotherapy. For this purpose we measured bone mineral density (BMD) and evaluated bone metabolism markers. METHODS: Seventy-five patients (37 female, 38 males, mean age 10.77±3.80 years) were included. Lumbar spine BMD was measured by dual energy X-ray absorptiometry and serum calcium, phosphorus, magnesium, alkaline phosphatase, parathyroid hormone and 25OH vitamin D levels were analyzed. For characteristics of all patients at diagnosis data were retreived from hospital records and analyzed retrospectively. RESULTS: A total of 18.66% (14 patients) of patients were osteoporotic (z score <-2 SD), 22.67% (17 patients) were osteopenic (z-score between -2 and -1 SD) and 58.67% (44 patients) presented normal z-scores (>-1 SD). There were no statisticaly significant differences between normal, osteopenic and osteoporotic groups for mean serum vitamine D (P=0.677), calcium (P=0.280), phosphorus (P=0.179), magnesium (P=0.675), ALP (P=0.092) and serum PTH (P=0.915) levels. According to ages (P=0.745) and gender (P=0.810) there were no significant differences in BMD. There were no significant differences between normal, osteopenic and osteoporotic patients for the total dose of prednisolone (P=0.334), dexamethasone, (P=0.734), methotrexate (P=0.911), granulocyte colony-stimulating factor (P=0.173) and cranial irradiation (P=0.912) they have received during chemotherapy. Bone fracture and aseptic necrosis rates were 12%, 8%, respectively. CONCLUSION: Osteoporosis and osteopenia are still observed in high rates after chemotherapy. We must be aware of this morbidity and must screen the patients for decreased BMD during the long duration of leukemia treatment. Supportive treatments should be evaluated to minimize these serious complications.

RESUMO

OBJECTIVE: This study sought to evaluate the hemodynamic changes of and to analyze the effects of coronary artery disease (CAD) as well as its risk factors on hemodynamic parameters during the reperfusion phase (RP) in adult living donor liver transplantation (ALDLT). PATIENTS AND METHODS: This single-center retrospective study evaluated 154 adult patients being assessed from January 2001 to December 2013 for orthotopic liver transplantation (OLT). The patients were divided into separate groups according to the presence or absence of CAD and its risk factors, including diabetes, hypertension, dyslipidemia, smoking, sex, and age. The hemodynamic parameters were noted during the RP with respect to the patient files. The comparison of the groups and the effects of cardiovascular problems on hemodynamic parameters were statistically analyzed. RESULTS: A decrease of more than 20% in systolic arterial pressure was seen in 16 (16.7%), 7 (43.8%), and 17 (40.5%) patients without CAD, with CAD, and with its high risk factors (>2), respectively (P < .05). Moreover, diastolic hypotension was seen in 59 (38.3%) patients during RP; of those, 10 (62.5%) had CAD and 19 (45.2%) had CAD high-risk factors. The decline in both systolic and diastolic arterial pressure was significantly correlated with the increased number of risk factors (P < .05). CONCLUSIONS: RP in ALDLT remains an issue not only for the surgeons but also for the anesthesiologists. Clinicians should be aware of CAD and its risk factors before OLT and successful management of such problems are mandatory for hemodynamic stability during this formidable process.

RESUMO

BACKGROUND: This study aims to identify prognostic factors and to develop a risk model predicting survival in patients undergoing secondary cytoreductive surgery (SCR) for recurrent epithelial ovarian cancer. METHODS: Individual data of 1100 patients with recurrent ovarian cancer of a progression-free interval at least 6 months who underwent SCR were pooled analysed. A simplified scoring system for each independent prognostic factor was developed according to its coefficient. Internal validation was performed to assess the discrimination of the model. RESULTS: Complete SCR was strongly associated with the improvement of survival, with a median survival of 57.7 months, when compared with 27.0 months in those with residual disease of 0.1-1 cm and 15.6 months in those with residual disease of >1 cm, respectively (P<0.0001). Progression-free interval (≤23.1 months vs >23.1 months, hazard ratio (HR): 1.72; score: 2), ascites at recurrence (present vs absent, HR: 1.27; score: 1), extent of recurrence (multiple vs localised disease, HR: 1.38; score: 1) as well as residual disease after SCR (R1 vs R0, HR: 1.90, score: 2; R2 vs R0, HR: 3.0, score: 4) entered into the risk model. CONCLUSION: This prognostic model may provide evidence to predict survival benefit from secondary cytoreduction in patients with recurrent ovarian cancer.

RESUMO

INTRODUCTION: A dyshomeostasis of macro- and micronutrients, including vitamin D and oxidative stress, are common pathophysiologic features in patients with congestive heart failure (CHF). In African Americans (AA) with CHF, reductions in plasma 25(OH)D are of moderate-to-marked severity (<20 ng/mL) and may be accompanied by ionized hypocalcemia with compensatory increases in serum parathyroid hormone (PTH). The management of hypovitaminosis D in AA with CHF has not been established. METHODS: Herein, a 14-week regimen: an initial 8 weeks of oral ergocalciferol (50,000 IU once weekly); followed by a 6-week maintenance phase of cholecalciferol (1400 IU daily); and a CaCO3 (1000 mg daily) supplement given throughout was designed and tested. Fourteen AA patients having a dilated (idiopathic) cardiomyopathy with reduced ejection fraction (EF, <35%) were enrolled: all completed the initial 8-week course; and 12 complied with the full 14 weeks. At baseline, 8 and/or 14 weeks, serum 25(OH)D and PTH; serum 8-isoprostane, a biomarker of lipid peroxidation, and echocardiographic EF were monitored. RESULTS: Reduced 25(OH)D at entry (14.4 ± 1.3 ng/mL) was improved (P < 0.05) in all patients at 8 weeks (30.7 ± 3.2 ng/mL) and sustained (P < 0.05) at 14 weeks (30.9 ± 2.8 ng/mL). Serum PTH, abnormally increased in 5 patients at baseline (104.8 ± 8.2 pg/mL), was reduced at 8 and 14 weeks (74.4 ± 18.3 and 73.8 ± 13.0 pg/mL, respectively). Plasma 8-isoprostane at entry (136.1 ± 8.8 pg/mL) was reduced at 14 weeks (117.8 ± 7.8 pg/mL; P < 0.05), whereas baseline EF (24.3 ± 1.7%) was improved (31.3 ± 4.3%; P < 0.05). CONCLUSIONS: Thus, the 14-week course of supplemental vitamin D and CaCO3 led to healthy 25(OH)D levels in AA with heart failure having vitamin D deficiency of moderate-to-marked severity. Albeit a small patient population, the findings suggest that this regimen may attenuate the accompanying secondary hyperparathyroidism and oxidative stress and improve ventricular function.

RESUMO

Inappropriately (relative to dietary Na(+)) elevated plasma aldosterone concentrations (PAC), or aldosteronism, have been incriminated in both the appearance of the cardiometabolic syndrome (CMS) and its progressive nature. The deleterious dual consequences of elevated PAC and dietary Na(+) have been linked to several components of the CMS, including salt-sensitive hypertension. Moreover, their adverse consequences are considered to be synergistic, culminating in a pro-oxidant phenotype with oxidative injury involving the heart and systemic tissues, including peripheral blood mononuclear cells (PBMC). Our experimental studies in rats receiving aldosterone/salt treatment have identified a common pathogenic event that links aldosteronism to the induction of oxidative stress. Herein, we review these findings and the important role of excessive intracellular Ca(2+) accumulation (EICA), or intracellular Ca(2+) overloading, which occurs in the heart and PBMC, leading to, respectively, cardiomyocyte necrosis with a replacement fibrosis and an immunostimulatory state with consequent coronary vasculopathy. The origin of EICA is based on elevations in plasma parathyroid hormone, which are integral to the genesis of secondary hyperparathyroidism that accompanies aldosteronism and occurs in response to plasma-ionized hypocalcemia and hypomagnesemia whose appearance is the consequence of marked urinary and fecal excretory losses of Ca(2+) and Mg(2+). In addition, we found intracellular Ca(2+) overloading to be intrinsically coupled to a dyshomeostasis of intracellular Zn(2+), which together regulate the redox state of cardiac myocytes and mitochondria via the induction of oxidative stress and generation of antioxidant defenses, respectively. To validate our hypothesis, a series of site-directed, sequential pharmacological and/or nutriceutical interventions targeted along cellular-molecular cascades were carried out to either block downstream events leading to the pro-oxidant phenotype or to enhance antioxidant defenses. In each case, the interventions were found to be cardioprotective. These cumulative salutary responses raise the prospect that pharmacological agents and nutriceuticals capable of influencing extra- and intracellular Ca(2+) and Zn(2+) equilibrium could prevent adverse cardiac remodeling and thereby enhance the management of aldosteronism.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the prevalence and spectrum of a known founder mutation, 5382insC and large genomic rearrangements (LGRs) in BRCA1 in ovarian cancer patients in Turkey. The additional aim was to determine the genetic testing strategy in Turkish breast/ovarian cancer family. METHODS: Six hundred and sixty-seven ovarian cancer patients from five large geographical regions in Turkey, 61 of which had family history of breast/ovarian cancer, were tested for the mutation 5382insC by mutagenically separated polymerase chain reaction and direct sequencing of the entire coding sequence and the splicing sites. Additionally, multiplex ligation-dependent probe amplification (MLPA) was performed for large mutational scanning of BRCA1 gene in unselected ovarian cancer. RESULTS: In this study, BRCA1 point mutations were observed in 1% of all patients and 9.8% of familial cases: 5382insC, unique novel missense variant-G1748S and unclassified splice site variant IVS20+5A>T. 5382insC was observed in two patients. However, G1748S, previously unreported, was found in four patients and thus led to the conclusion that this mutation may be unique to Turkey. A splice site variant, IVS20+5A>T, was detected in three patients, with two of them including G1748S and IVS20+5A>T, together. Using MLPA, six different distinct LGRs in BRCA1 were observed: the deletion of E1A-1B-2, E11, E17-19, E18 and E18-19 and duplication of E5-9. The prevalence of LGRs in this study was 40.9% among patients with family history. The deletion of E1A-1B-2 was the common mutation, and patients with this deletion were referred to us from four different geographical regions in Turkey. Therefore, it was hypothesized that this deletion covering E1-2 is common in Turkey. CONCLUSION: LGRs in BRCA1 were strongly associated with positive family history among the Turkish population. On the basis of these findings, it can be recommended that a low-cost screening for LGRs in BRCA1 may be the first-line mutation detection method in families with strong breast/ovarian cancer history in Turkey.

RESUMO

AIM: To identify self-reported perceptions of the barriers to research utilisation by Turkish staff nurses working in a university hospital and to ascertain whether involvement in research-related activities influenced their perception of the barriers. BACKGROUND: Research utilisation in nursing has been a prominent concern for the last 30 years. While investigators in several countries have identified nurses' perception of barriers to research utilisation, this is the first study to investigate such barriers in Turkey. DESIGN: This is a descriptive, cross sectional study with a sample of 329 staff nurses working in a university hospital. Two instruments were used; a demographics questionnaire that investigated research activities and the Barriers Scale to measure perceptions. An additional item, 'studies are published in English' was added to the scale. RESULTS: The lack of time to implement new ideas was the most frequently, 84·5%, perceived barrier. The second most frequently perceived barrier was difficulty in reading English. The top six barriers were all related to the setting. Additionally, research-active nurses found insufficient time less of a barrier but unawareness of research findings and being isolated from knowledgeable colleagues as greater barriers to research utilisation. CONCLUSIONS: Turkish nurses' perception of barriers is similar to the findings in other countries, i.e., that the top six barriers were related to setting. Language barrier compares similarly with studies in other countries that investigated this variable. RELEVANCE TO CLINICAL PRACTICE: The gap between theory and practice in nursing can be minimised by identifying strategies to increase research utilisation in clinical settings. Such strategies can also improve patient care outcomes.

RESUMO

OBJECTIVE: No attention has been paid in the past to the spread pattern of right and left epithelial carcinomas of the ovaries. We aimed to investigate the incidence, spread pattern and distribution of lymph node metastasis in epithelial ovarian cancer (EOC), comparing right versus left EOC of any stage, where the contralateral ovary is apparently and histologically tumor-free. METHODS: Out of a total of 442 patients with EOC, 318 (72%) patients in the study had bilateral and 124 (28%) patients had unilateral ovarian cancer. The study enrolled 60 (48%) patients with right and 64 patients with left ovarian involvement (52%) where the contralateral ovary was tumor-free. Groups Right and Left were compared in terms of age, the tumor status of the lymph nodes, surgical stage, histology, grade, tumor extension out of the ovaries, omental tumor involvement and also omental and nodal involvement together. RESULTS: The comparisons of the variables between Groups Right and Left did not show significant differences except for metastasis patterns in the left iliac lymph nodes and omentum (p < 0.05). Independent of age and histological type of the tumor, women with left-side EOC showed a significantly higher incidence of metastasis in the left iliac lymph nodes (OR: 7.04, 95% CI, 1.36-36.44) and omentum (OR: 2.87, 95% CI, 1.03-8.01), when compared to right-side EOC (p < 0.05). CONCLUSION: In this cohort of patients, we found that left-side unilateral EOC was more likely to metastasize to the left iliac lymph nodes and omentum than the right side where the contralateral ovary was tumor-free. This might be due to the difference in lymphatic drainage on the right and left side and/or the influence of peritoneal fluid movements. This suggestion needs to be supported by further studies.

RESUMO

Endometrial hyperplasia is a commonly seen disorder in daily gynecology practice. The clinical importance of this pathological entity is the underlying risk of carrying a concomittant genital cancer or risk of progression to endometrial carcinoma during the follow-up. Despite recent advances in non-invasive techniques to define underlying endometrial cancer during the initial diagnosis of endometrial hyperplasia, none of these studies are conclusive yet. Today, in spite of intense discussions and related studies which aimed to define certain prognostic factors (WHO94 vs EIN) to predict cases that would progress to cancer, we still do not have a practical and accurate system available to use during daily practice. Treatment of endometrial hyperplasias depends on the patient's age, fertility desire and the type of hyperplasia. Progestagens are still the most commonly used medical treatment modality in these patients. Response rates are higher for cases without atypia. In selected cases, hysterectomy may be performed as a definitive treatment modality. In this review article, the current management of endometrial hyperplasias is summarized in light of the associated literature.

RESUMO

Primary breast carcinoma is the most common malignancy in women, however, metastatic breast carcinoma is rarely seen in clinical practice. It has been reported that lymphoma-leukemia, melanoma and sarcomas, the most common primary malignancies, can metastasize to the breast. On the other hand, ovarian carcinoma and other gynecologic cancers rarely develop into breast metastasis. However, the incidence of breast metastasis arising from ovarian carcinoma might be increasing as a result of prolongation in survival and improvement in treatment modalities. Bilateral breast metastasis originating from an ovarian carcinoma is an extremely rare clinico-pathological situation. In our literature review we found just nine cases of bilateral breast metastasis from primary ovarian carcinoma. In this study, the mean age was 46 years (range 16-68). Mean interval from initial diagnosis of ovarian carcinoma to bilateral breast metastases was 22 months (range 11-24) and mean survival was 12 (range 5-27) months after the diagnosis of breast metastasis. Serous papillary adenocarcinoma was the predominant histological subtype. Interestingly, five of the nine (56%) cases reported were from Turkey. This interesting observation can be explained by a genetic predisposition, but it requires further research. In conclusion, although it is a rare entity, breast metastasis should not be ruled out in patients with a history of ovarian carcinoma, if patients present with any symptoms of breast diseases.

RESUMO

Radiotherapy with or without surgery for the treatment of pelvic malignancies irreversibly destroys the hormonal activity and reproductive capacity of ovaries in young women. On the other hand, menopausal symptoms associated with estrogen deficiency is an important contributor to the poor quality of life scores in gynecologic cancer survivors. Transposing of the ovaries into the paracolic gutters (ovarian transposition) was described in 1958 with the aim of protecting gonadal functions in reproductive-aged women treated by pelvic radiotherapy and/or surgery. Although the laparatomic approach has been used as a parallel to development in endoscopic surgery, today it is generally performed laparoscopically. However, there is ongoing debate about the effectiveness of ovarian tranposition with respect to protecting gonadal functions. Moreover, metastasis to the transposed ovaries and port sites is another concern about this procedure. In this short review, indications, techniques and functional outcomes of ovarian transposition have been summarized.

RESUMO

The causes of systemic venous hypertension (SVHT) include cardiac- and circulatory-related factors, whereas its consequences include the congestion of hepatic, splanchnic, and peripheral circulations, which contribute significantly to the clinical congestive heart failure syndrome. Based on a disequilibrium in hydrostatic and oncotic pressures, the increased filtration and formation of interstitial fluid at these sites with an accompanying increase in lymph flow mandates an increment in lymphatic drainage to protect against such congestion and the appearance of edema and ascites. However, lymph flow via the thoracic duct into systemic veins is opposed by elevations in central venous pressure. Various management strategies have the potential to prevent and/or correct SVHT. The case of a 54-year-old man with a dilated cardiomyopathy who presented with decompensated biventricular failure, expressed as anasarca and ascites, is used to illustrate the importance of SVHT.

RESUMO

Primary cytoreductive surgery followed by combination chemotherapy of paclitaxel and cisplatinum is the standard treatment for advanced staged epithelial ovarian cancers. Despite the maximal efforts to increase optimal cytoreductive success rates and related ultra-radical surgeries, five-year survival rates are still poor. Primary cytoreductive surgeries and their radicalities have been criticized since the early nineties. Interval debulking surgery (IDS) and neo-adjuvant chemotherapy (NAC) are the two suggested alternatives to the primary debulking approaches. In this article, the authors summarize and discuss the IDS approach with an associated literature review.

RESUMO

The objective of this study was to analyze the efficacy and morbidity of vaginal cuff brachytherapy alone in intermediate- to high-risk stage I endometrial cancer patients after complete surgical staging. Between October 1994 and November 2005, 128 patients with intermediate- to high-risk stage I endometrial adenocarcinoma were treated with high dose rate (HDR) brachytherapy alone after complete surgical staging. The intermediate- to high-risk group was defined as any stage I with grade 3 histology or stage IB grade 2 or any stage IC disease. The comprehensive surgery was in the form of total abdominal hysterectomy, bilateral salpingo-oophorectomy in addition to infracolic omentectomy, and routine pelvic and para-aortic lymphadenectomy. The median number of the lymph nodes dissected was 33. The median age at the time of diagnosis was 60 years. Forty patients were staged as IB (grade 2: 25 and grade 3: 15), and 88 patients were staged as IC (grade 1: 31, grade 2: 41, and grade 3: 16). A total dose of 27.5 Gy with HDR brachytherapy, prescribed at 0.5 cm, was delivered in five fractions in 5 consecutive days. Median follow-up was 48 months. Six (4.7%) patients developed either local recurrence (n = 2) or distant metastases (n = 4). Five-year overall survival and disease-free survival (DFS) rates are 96% and 93%, respectively. Only age was found to be significant prognostic factor for DFS. Patients younger than 60 years have significantly higher DFS (P = 0.006). None of the patients experienced grade 3/4 complications due to the vaginal HDR brachytherapy. Vaginal cuff brachytherapy alone is an adequate treatment modality in stage I endometrial adenocarcinoma patients with intermediate- to high-risk features after complete surgical staging with low complication rates.
