A Hypofractionated Radiotherapy Schedule with a Simultaneous Integrated Boost for Breast Cancer: Outcomes including Late Toxicity and Health Quality.

Introduction: This study aimed to evaluate the long-term adverse effects on the physical appearance and overall well-being of breast cancer patients who receive hypofractionated radiotherapy as whole breast and simultaneous integrated boost (SIB) treatment, utilizing intensive modulated radiotherapy (IMRT), volumetric modulated arc therapy (VMAT), or a hybrid therapy approach. Material/Methods: This investigation involved administering hypofractionated SIB-VMAT therapy to individuals diagnosed with early-stage breast cancer. Treatment was carried out over a three-week period in which a total dose of 48.06 Gy was given to the entire breast and 54 Gy was given to the tumor bed. Data on skin toxicity and cosmetic outcomes were analyzed both during the acute phase and during the three-month and five-year follow-up periods after treatment. Results: A total of 125 patients treated between December 2014 and December 2016 were included in the study. The data of these patients with at least 5 years of follow-up were analyzed. Conclusions: Considering these long-term results, hypofractionated SIB-VMAT can be considered a viable treatment choice, even for patients with unfavorable conditions.

Same Chemotherapy Regimen Leads to Different Myelotoxicity in Different Malignancies: A Comparison of Chemotherapy-Associated Myelotoxicity in Patients With Advanced Ovarian and Non-Small-Cell Lung Cancer.

Carboplatin-paclitaxel chemotherapy combination is the standard first-line treatment of advanced ovarian cancer and is the most commonly used treatment combination shown to be effective in advanced non-small-cell lung cancer (NSCLC). The most important dose-limiting side effect is hematologic toxicity. In this study, the severity of treatment-related myelotoxicity is compared in patients with advanced ovarian and lung cancers who received same schedule of carboplatin-paclitaxel. The study was prospectively performed from February 2009 to July 2011 and involved 103 patients with stages Ic-IV ovarian (n = 51) and advanced NSCLC (n = 52) who were administered a maximum of 6 cycles of carboplatin-paclitaxel as a first-line treatment. Full blood counts were measured before treatment, before each chemotherapy cycle during therapy, and at the first and sixth month after therapy. The median ages were 59 years (range, 35-77 years) for patients with NSCLC and 56 years (range, 38-75 years) for patients with ovarian cancer. The frequencies of anemia were 17% and 28.6% before the initiation of chemotherapy, 39.2% and 68.0% at the third cycle of treatment, and 44.2% and 45.2% at the sixth cycle of treatment in patients with NSCLC and ovarian cancer, respectively. Initial leukopenia rates were 3.4% and 0%; at the third cycle 46.0% and 41.2%; and at the sixth cycle 41.9% and 48.8% in patients with NSCLC and ovarian cancer, respectively. At the third cycle, 2.5% of the patients with NSCLC and 10.4% of the patients with ovarian cancer had thrombocytopenia, and at the sixth cycle, 23.3% of the patients with NSCLC and 25% of the patients with ovarian cancer had thrombocytopenia. Hemoglobin, leukocyte, and platelet values at the third cycle were significantly lower than those at admission in both cancer groups. Declines in hemoglobin levels in patients with NSCLC and in platelets in patients with ovarian cancer at the sixth cycle were statistically significant compared with the third cycle. In conclusion, the same schedule of chemotherapy may lead to different myelotoxicities in different types of cancer. These results should be taken into consideration in terms of supportive care and management of toxicity.

Epidermal growth factor receptor in CRC patients in the era of the RAS.

The aim of this study was to investigate EGFR expression patterns and the effect of EGFR expression on stage, prognosis and response to conventional chemotherapy agents other than monoclonal antibodies in CRC patients. This study included 59 metastatic CRC patients. The expression of EGFR was quantified by immunochemistry in biopsy specimens that were obtained before treatment was initiated. The cases were considered to be positive for EGFR if >1% of the tumor cells had complete circumferential membranous staining. The median age of the patients was 54.6 years, and 59% of the patients were male. Twenty-six patients presented with stage IV disease, and the remaining patients developed distant metastasis during follow-up. Fifty-one patients were treated with regimens containing irinotecan. The numbers of patients with EGFR expression in the primary tumors, the metastatic lymph nodes and the normal colonic tissue were 34 (65.4%), 10 (76.9%) and 34 (65.4%) respectively. The initial disease stage and lymph node stage were correlated with EGFR expression (p<0.05). Additionally, EGFR positivity was correlated with a statistically significant reduction in the response rate to chemotherapy, the overall survival (21 vs. 28 months) and the progression-free survival (15 vs. 22 months) in metastatic patiens treated with chemotherapy other than targeted therapies. In conclusion, EGFR expression in correlated with stage in all CRC patients and response to chemotherapy and survival in metastatic CRC patients.

High serum transforming growth factor beta 1 (TGFB1) level predicts better survival in breast cancer.

The transforming growth factor beta 1 (TGFB1) is a regulatory cytokine with both tumor suppressor and tumor-promoting effects in breast cancer (BC) cell lines and tissue. Data about level of circulating TGFB1 and its prognostic significance in BC patients is conflicting. The objective of this study is to determine the clinical significance of the serum TGFB1 levels in BC patients. We enrolled 96 female patients with histopathologically diagnosed BC who did not receive chemotherapy (CT) or radiotherapy. Serum TGFB1 levels were measured by ELISA method and compared with 30 healthy controls. The mean serum TGFB1 level of BC patients was significantly higher than controls (0.08 vs. 0.04 ng/ml, p < 0.001). There was no significant difference according to known disease-related clinicopathological or laboratory parameters. Serum TGFB1 level had a significant impact on overall survival in both univariate (p = 0.01) and multivariate analysis (p = 0.013). Serum TGFB1 level is elevated in BC patients and has a favorable prognostic value. However, it has no predictive role on CT response.

The behavior of Turkish cancer patients in fasting during the holy month of Ramadan.

OBJECTIVE: Fasting during the holy month of Ramadan is one of the major obligations for all adult Muslims. We performed a survey of Turkish Muslim cancer patients to examine the extent of their fasting status and to compare various clinical characteristics of fasting and non-fasting cancer patients during the month of Ramadan. METHODS: This study was conducted on 701 adult cancer patients who attended ambulatory patient care units answered the questionnaires. RESULTS: The population comprised 445 women (63.5%), and the median age was 54 years. Before diagnosis of cancer, 93.1% of the patients used fast consists of completely (78.3%) and partial (14.8%). However, 15% of cases were fasting on the day of interview, either partially (7.4%) or completely (7.6%) with equal distributions. Patients who were females, those with good performance status, those without any comorbid disease, who had non-metastatic disease, those with history of surgery, those treated with radiotherapy and those being treated with oral chemotherapeutic agents were more likely to be fasting than others. The fasting ones had more prevalent among patients with lymphoma, urogenital cancer and breast cancer; conversely, the rate of fasting status among patients with lung and gastrointestinal cancer was quite low. Only 20.8% of all patients asked their physician whether it was alright for them to fast and physicians generally had a negative attitude towards fasting (83.2%). CONCLUSIONS: Majority of cancer patients are not fasting during the month of Ramadan, and a small part of patients consult this situation to their physician.

A multicenter, retrospective archive study of radiological and clinical features of ALK-positive non-small cell lung cancer patients and crizotinib efficacy.

To evaluate radiological and clinical features in metastatic anaplastic lymphoma kinase+ non-small cell lung cancer patients and crizotinib efficacy in different lines. This national, non-interventional, multicenter, retrospective archive screening study evaluated demographic, clinical, and radiological imaging features, and treatment approaches in patients treated between 2013-2017. Totally 367 patients (54.8% males, median age at diagnosis 54 years) were included. Of them, 45.4% were smokers, and 8.7% had a family history of lung cancer. On radiological findings, 55.9% of the tumors were located peripherally, 7.7% of the patients had cavitary lesions, and 42.9% presented with pleural effusion. Pleural effusion was higher in nonsmokers than in smokers (37.3% vs. 25.3%, P = .018). About 47.4% of cases developed distant metastases during treatment, most frequently to the brain (26.2%). Chemotherapy was the first line treatment in 55.0%. Objective response rate was 61.9% (complete response: 7.6%; partial response: 54.2%). The highest complete and partial response rates were observed in patients who received crizotinib as the 2nd line treatment. The median progression-free survival was 14 months (standard error: 1.4, 95% confidence interval: 11.2-16.8 months). Crizotinib treatment lines yielded similar progression-free survival (P = .078). The most frequent treatment-related adverse event was fatigue (14.7%). Adrenal gland metastasis was significantly higher in males and smokers, and pleural involvement and effusion were significantly higher in nonsmokers-a novel finding that has not been reported previously. The radiological and histological characteristics were consistent with the literature data, but several differences in clinical characteristics might be related to population characteristics.

Clinical and prognostic significance of coagulation assays in advanced epithelial ovarian cancer.

OBJECTIVE: Epithelial ovarian cancer (EOC) is the leading cause of death among gynecological tumors and usually diagnosed at advanced stage. We aimed to identify the clinical and prognostic relevance of coagulation tests and their correlation with serum CA-125 levels in advanced EOC. MATERIALS AND METHODS: A total of 33 advanced-stage (stages III and IV) EOC patients were enrolled in the study. Of these patients, 17 had received neoadjuvant chemotherapy and 16 patients received chemotherapy after optimal debulking surgery. Several clinicopathologic factors, coagulation assays, routine biochemistry tests, and serum CA-125 levels were evaluated before treatment and compared with healthy subjects. RESULTS: All coagulation tests including prothrombin time (PT), activated partial thromboplastin time, international normalized ratio, fibrinogen, D-dimer, and platelet revealed statistically significant difference between patients and control subjects (P ≤ 0.001). Elevated CA-125 levels were correlated with higher D-dimer values (P = 0.03). Prolonged PT was associated with poorer both overall (P = 0.03) and progression-free survival rates (P = 0.04). CONCLUSIONS: Correlation of CA-125 with D-dimer is supposed to reflect hyperactivation of fibrinolytic pathway in the presence of a higher tumor load. Alterations in coagulation pathway reflected by prolonged PT support prognostic effects on survival of advanced-stage EOC patients.

Performance status of patients is the major prognostic factor at all stages of pancreatic cancer.

BACKGROUND: The aim of this study was to identify and evaluate the clinicopathologic factors and to elucidate the clinical importance of performance status on the outcome of patients with pancreatic cancer. MATERIALS AND METHOD: The data of 335 patients with histologically confirmed diagnosis of pancreatic cancer who were treated and followed up between 2000 and 2010 were recorded from medical charts. RESULTS: The median age of the patients was 59 years (range 25-88 years) and 226 (67.5%) were male. The study group comprised localized disease (18%), locally advanced disease (36%) and metastatic disease (46%). The median survival of all patients was 280 days and the 4-year survival rate was 5%. Univariate analysis indicated that initial poor performance status of patients (PS 2-4) was significantly associated with shorter survival in localized (p = 0.015), locally advanced (p = 0.01), metastatic stage (p < 0.001) and in the whole group (p < 0.001). Multivariate analyses also showed the same findings except in local disease (p = 0.04 for locally advanced disease, p = 0.002 for metastatic stage, and p < 0.001 for all stages). In patients with poor performance status, severe weight loss (>10%) (p = 0.007), large tumor diameter (>3 cm) (p = 0.046), and especially metastatic disease (p < 0.001) were associated with significantly shorter overall survival. CONCLUSIONS: The performance status of a patient is the major prognostic factor predicting overall survival for all stages of pancreatic cancer. Severe weight loss, large tumor, and metastatic disease were found to be unfavorable prognostic factors in patients with poor performance status.

Adrenocortical carcinoma: clinicopathological features, prognostic factors and outcome.

OBJECTIVE: The purpose of this study was to investigate the clinicopathological characteristics and treatment outcomes of patients with adrenocortical carcinoma (AC). METHODS: Twenty-four patients (10 females and 14 males) diagnosed with AC between 1998 and 2009 were evaluated. Clinical features and outcomes were reviewed. RESULTS: Median age was 46.5 years. One (4%) patient was classified as stage I, 10 (42%) were classified as stage II, 8 (33%) were classified as stage III and 5 (21%) were classified as stage IV. Tumor sizes ranged from 3 to 22 cm with a mean diameter of 11 cm. Five patients were locally inoperable at initial diagnosis. In addition to surgery, 2 of 19 patients were treated with an adjuvant cisplatin plus etoposide regimen. Sixteen patients were treated with chemotherapy after recurrence. Median survival time was 18 months. The 1- and 5-year overall survival estimates were 73 and 48%, respectively. Mean survival times for male and female patients were 58 and 12 months, respectively (p = 0.046). Early T stage (p = 0.04), lymph node negativity (p < 0.001), the absence of distant metastases (p < 0.001) and early stage (p < 0.001) were correlated with overall survival. CONCLUSION: AC is a rare disease with a poor prognosis. There are correlations between gender, stage and survival.

Complete response in a patient with granulosa cell tumor treated with a combination of leuprolide and tamoxifen.

BACKGROUND: Adult granulosa cell tumors (GCTs) are frequently hormonally active. Thus, hormonal agents have been evaluated for the treatment of advanced-stage or recurrent disease. CASE REPORT: A 39-year-old patient presented with recurrent GCT. The patient received multiple treatment modalities, including surgery and 2 different chemotherapy regimens (cisplatin- and taxanebased). Abdominal computed tomography following these treatments showed local recurrence with multiple implants. The patient's inhibin B level increased to 187 pg/ml at this time. The patient was treated with leuprolide 11.25 mg every 3 months and tamoxifen 20 mg twice daily. The patient's inhibin B level began to decrease after 1 month and returned to normal after 4 months. The patient has been maintained on this treatment for 2 years and has tolerated the drugs well. CONCLUSION: The combination of leuprolide and tamoxifen had limited side effects in the presented patient and might be a viable treatment option for women with advanced-stage or recurrent adult ovarian GCTs.

Determination of heavy metals in Lower Sakarya River sediments using a BCR-sequential extraction procedure.

A BCR-sequential extraction procedure for the determination of extractable heavy metals was applied to sediments of various rivers and lakes. There are many rivers basins in Turkey. Sakarya River Basin is one of the most important basins, which consists of three parts: Upper, Middle and Lower Sakarya River Basins. In this study, the Lower Sakarya River was selected as the study area for sediments. The samples were collected monthly from 10 pre-determined stations through the river for 10 months time and analysed for the distribution of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn elements. The determination of extractable heavy metals in sediments was carried out by using Flame Atomic Absorption Spectrometer. The validation of the results was performed by the analysis of a BCR 701 standard reference material.

Noncutaneous melanoma have distinct features from each other and cutaneous melanoma.

OBJECTIVE: Compared to the cutaneous melanoma, noncutaneous melanomas are relatively rare and have a distinct pattern of behavior. We performed this study to define the clinical characteristics and outcomes of patients with noncutaneous melanomas and emphasize how they differ from cutaneous melanomas. METHODS: 216 patients who were diagnosed with noncutaneous melanoma were assessed and their medical records between 2000 and 2010 were retrieved from the cancer registry. 475 patients with cutaneous melanoma were used for comparison. RESULTS: Of the 216 noncutaneous melanoma patients, 83 had mucosal melanoma, 101 had ocular melanoma and 32 had unknown primaries. For mucosal melanoma, the head and neck was the most common anatomic site (53%), followed by the gastrointestinal tract (37%), female genital (6%) and urinary tract (4%). The majority of the ocular melanomas (94%) originated in the uvea. 32 patients demonstrated a primary unknown disease with regional metastasis as the dominant behavior (72%). Age was found to be statistically significantly different among melanoma patients (p < 0.001). Younger patients had more cutaneous and unknown primary melanomas, whereas older patients had more ocular and mucosal melanoma. In subset analyses, we found significant differences between cutaneous and ocular (p = 0.038) or mucosal (p < 0.001) melanomas. The ratios of metastasis on admission were higher in patients with mucosal (27.7%) and unknown primary (28.1%) melanomas, and lower for ocular (3%) melanomas (p < 0.001). Patients with cutaneous melanoma had an intermediate (12%) ratio. Patients with ocular melanoma had better outcome than patients with other melanoma sites (p < 0.05). While overall survival for cutaneous melanoma was significantly negatively correlated with male gender (p < 0.001), advanced stages (p < 0.001) and old age (p = 0.005), stage IV disease was the only independent prognostic factor in patients with ocular melanoma (p = 0.006). No prognostic factor for outcome was found for either mucosal or unknown primary melanomas. CONCLUSION: The clinical presentations and prognoses of different primary sites of melanoma are distinctive. Therefore, approaches to these melanomas should be different.

Clinical and pathological features of breast cancer associated with the pathological complete response to anthracycline-based neoadjuvant chemotherapy.

OBJECTIVE: Patients with breast cancer with a pathological complete response (pCR) after neoadjuvant chemotherapy (NAC) have a better prognosis than patients with residual disease. The aim of the current study was to identify predictors of pCR. METHODS: This retrospective study included 388 patients treated with anthracycline-based NAC. Clinicopathological parameters were compared between the patients with and without pCR in breast and axilla. RESULTS: Treatment consisted of FAC/FEC in 230 patients (59%), TAC in 39 (10%) patients and AC followed by docetaxel in 119 (31%). In all, 36 (9.3%) patients had pCR. In univariate analysis, age, tumor size, lymph node involvement, tumor grade (p = 0.077, n = 265), ER and HER-2 status (n = 213), lymphovascular invasion (LVI), type of chemotherapy and taxane-containing chemotherapy were associated with pCR. In multivariate analysis, ER negativity (p = 0.003), the absence of LVI (p = 0.009) and taxane-containing NAC (p = 0.026) were found to be significant indicators of pCR. Median follow-up time was 69 months. Progression-free survival was significantly improved in patients achieving pCR (p = 0.001). CONCLUSIONS: pCR is associated with a better outcome regardless of clinical and pathological parameters in breast cancer patients who receive NAC. The probability of pCR was higher in ER-negative, LVI-negative tumors and in patients treated with sequential taxane-containing chemotherapy.

The first case of primary testicular germ cell tumor containing nephroblastoma as the only one non-germ cell component.

Adult extrarenal nephroblastomas (Wilms' tumor) are extremely rare tumors. They show a higher incidence of non-seminomatous elements and these so-called 'teratoid' Wilms' tumors are suggested to be of germ cell origin. To date, however, the number of reported cases with gonadal teratoma containing nephroblastoma is very low, and due to this reason, there are no standardized criteria for the categorization and treatment of these lesions. To our knowledge, the first case of nephroblastoma arising in a non-atrophic testis has been reported and it is associated with a teratoma as morphologically identifiable germ cell tumor and rhabdomyosarcoma as a second non-germ cell element. We report the second case of an adult nephroblastoma that arose within the primary testicular teratoma in a non-atrophic testis. Teratoma and nephroblastoma within the same testis may have an important point to clarify the developmental mechanism in nephroblastomatous differentiation of germ cell tumors.

Surveillance results of patients with stage I nonseminomatous germ cell testicular cancer.

BACKGROUND: The aim of this study was to evaluate the efficacy of active surveillance after radical orchiectomy in patients with clinical stage I nonseminoma. PATIENTS AND METHODS: Between 2002 and 2009, the charts of 80 patients who were offered active surveillance were studied retrospectively. Patients underwent clinical, radiologic, and biochemical examinations according to NCCN follow-up guidelines in nonseminoma. RESULTS: 70 of 80 patients who accepted this strategy were analyzed. 12 of the 70 patients (17%) had relapses with a median follow-up of 18.5 months (6-76). Relapses were found in retroperitoneal lymph nodes in 3 patients. 5 patients had marker relapse, and 4 patients developed both marker relapse and retroperitoneal lymph node metastases. 10 of the 12 patients (83%) had relapsed within 1 year. There were no statistically significant differences in lymphovascular invasion and germ cell components between relapsed and non-relapsed patients. 11 of the 12 patients were treated with cisplatinbased combination chemotherapy, and 1 patient underwent retroperitoneal lymph node dissection. Only 2 patients underwent primary retroperitoneal lymph node dissection for rest nodules. CONCLUSIONS: Surveillance could be a reliable strategy in compliant stage I nonseminoma patients. Recurrences can be detected early and treated successfully.

Prognostic and Predictive Role of Angiogenic Markers in Non- Small Cell Lung Cancer

Objective: Despite the existence of detailed consensus guidelines, challenges remain regarding the role angiogenetic factors on non-small cell lung cancer (NSCLC). This study was conducted to determine the role of the vascular endothelial growth factor (VEGF), interleukin-8 (IL-8) and angiopoietin2 (Ang2) in patients with NSCLC. Methods: This study included 64 consecutive patients with non-small cell lung cancer, who admitted to clinic. Pre-treatment serum VEGF, IL-8 and Ang2 levels were evaluated. Patients were treated according to internationally accepted guidelines. Results: VEGF and IL-8 serum levels of patients with both squamous cell carcinoma and adenocarcinoma were significantly higher than controls (p<0.05). In addition, IL-8 levels were lower among treatment-responders than non-responders (p:0.031). Impact of elevated or decreased levels of VEGF, Ang2 and IL-8 on survival was evaluated, accepting median level as reference. There was no correlation between the serum levels of VEGF, Ang2, IL-8 and survival. Conclusion: We found that the levels of angiogenic markers were significantly different between non-small cell lung cancer patients and controls. These markers could elicit more information related to stage and prognosis.

Survival Impact of Optimal Surgical Cytoreduction in Recurrent Epithelial Ovarian Cancer with Brain Metastasis.

AIM: The aim of this study was to determine the clinicopathological characteristics, treatment details and outcome of patients with brain metastasis from epithelial ovarian carcinoma (EOC). METHODS: This study included 21 patients diagnosed with brain metastasis from EOC between 1999 and 2009. RESULTS: Median age was 61 years (range 38-77). The median time elapsed from EOC diagnosis to brain metastasis detection was 32 months. Single brain metastases were found in 10 (48%) cases, and there was extra-cranial disease in 11 (52%) cases. During the mean 86 months of follow-up, 18 of the patients (86%) died of the disease and 3 (14%) were alive with disease. The median survival time after the initial diagnosis of brain metastasis was 9 months. The median overall survival (OS) from initial diagnosis of EOC was 50 months. In univariate analysis, prolonged time from initial diagnosis to central nervous system metastasis (more than 32 months) (p = 0.001), treatment with radiotherapy (p < 0.001), optimal cytoreductive operation (p = 0.02) were all positively correlated with OS. CONCLUSION: The prognosis of patients with brain metastasis from EOC is still poor. The significant predictors of survival in our series were whole brain radiotherapy, prolonged elapsed time from initial diagnosis to brain metastasis and optimal cytoreductive surgery.

Current adjuvant treatment modalities for gastric cancer: From history to the future.

The discrepancy between the surgical technique and the type of adjuvant chemotherapy used in clinical trials and patient outcomes in terms of overall survival rates has led to the generation of different adjuvant treatment protocols in distinct parts of the world. The adjuvant treatment recommendation is generally chemoradiotherapy in the United States, perioperative chemotherapy in the United Kingdom and parts of Europe, and chemotherapy in Asia. These options mainly rely on the United States Intergroup-0116, United Kingdom British Medical Research Council Adjuvant Gastric Infusional Chemotherapy, and the Asian Adjuvant Chemotherapy Trial of S-1 for Gastric Cancer and Capecitabine and Oxaliplatin Adjuvant Study in Stomach Cancer trials. However, the benefits were evident for only certain patients, which were not very homogeneous regarding the type of surgery, chemotherapy regimens, and stage of disease. Whether the dissimilarities in survival are attributable to surgical technique or intrinsic biological differences is a subject of debate. Regardless of the extent of surgery, multimodal therapy may offer modest survival advantage at least for diseases with lymph node involvement. Moreover, in the era of individualized treatment for most of the other cancer types, identification of special subgroups comprising those who will derive more or no benefit from adjuvant therapy merits further investigation. The aim of this review is to reveal the historical evolution and future reflections of adjuvant treatment modalities for resected gastric cancer patients.

Favorable survival time provided with radioembolization in hepatocellular carcinoma patients with and without portal vein thrombosis.

PURPOSE: Although some algorithms are defined for the treatment of advanced hepatocellular carcinoma (HCC), the expected survival cannot be prolonged as it is intended. Treatment options for this group of patients are limited. Radioembolization with yttrium-90 (Y-90) microspheres is a new treatment modality, which has also been used in advanced HCC patients. In this study, the authors aimed to assess the efficiency of radioembolization with Y-90 microspheres and evaluate prognostic factors that influence the survival in HCC patients. PATIENTS AND METHODS: The authors retrospectively evaluated data of 29 HCC patients who had radioembolization with Y-90 resin or glass microspheres between May 2009 and January 2014. Patient survival was evaluated by using the Kaplan-Meier method. Subgroup comparisons in terms of age, sex, prior treatment status before radioembolization, tumor burden, time between HCC diagnosis and radioembolization, alpha fetoprotein (AFP) level before radioembolization, presence of portal vein thrombosis (PVT), hepatopulmonary shunt ratio, extrahepatic disease burden, multifocality, bilaterality, Eastern Cooperative Oncology Group (ECOG), Child-Pugh, and Barcelona Clinic Liver Cancer (BCLC) status were performed to evaluate prognostic factors that affected survival. RESULTS: There were 29 HCC patients (mean age: 59.9±12 years) in the patient group. Grade ≤1 and 2 ECOG performance status was present in 19 and 10 patients, respectively. Twenty-six patients were classified as Child A and 3 patients as Child B. According to the BCLC staging system, 18 patients were in stage B and 11 patients were in stage C. PVT was diagnosed in 12 patients. The median follow-up was 15 months. The median overall survival was 17±2.5 months. BCLC disease stage was a significant prognostic variable associated with survival, but other parameters, even the presence of PVT, were found to be not significantly affecting survival. CONCLUSION: Radioembolization provides favorable survival time in advanced HCC patients. Even patients who are not eligible for transarterial chemoembolization due to PVT can have radioembolization without a decrease in the median survival time.
