Synchronous primary cancers: Renal cell carcinoma and rectal cancer.

Although cancers of rectum and kidney are common malignancies, the occurrence of primary synchronous neoplasms of these organs has been reported rarely. Very few case reports are available in literature till date. The relationship between these two events remains unclear, probably because of the rarity of the association. In this report, we describe incidentally detected renal cell carcinoma in an elderly man, during staging workup of rectal adenocarcinoma and both malignancies were surgically managed simultaneously with curative intent.

Recent advances in upper tract urothelial carcinomas: From bench to clinics.

Urothelial carcinoma in the upper tract is rare and often discussed separately. Many established risk factors were identified for the disease, including genetic and external risk factors. Radiographic survey, endoscopic examination and urine cytology remained the most important diagnostic modalities. In localized upper tract urothelial carcinomas, radical nephroureterectomy with bladder cuff excision are the gold standard for large, high-grade and suspected invasive tumors of the renal pelvis and proximal ureter, whereas kidney-sparing surgeries should be considered in patients with low-risk disease. Advances in technology have given endoscopic surgery an important role, not only in diagnosis, but also in treatment. Although platinum-based combination chemotherapy is efficacious in advanced or metastatic disease, current established chemotherapy regimens are toxic and lack a sustained response. Immune checkpoint inhibitors have led to a new era of treatment for advanced or metastatic urothelial carcinomas. The remarkable results achieved thus far show that immunotherapy will likely be the future treatment paradigm. The combination of immune checkpoint inhibitors and other agents is another inspiring avenue to explore that could benefit even more patients. With respect to the high incidence rate and different clinical appearance of upper tract urothelial carcinomas in Taiwan, a possible correlation exists between exposure to certain external risk factors, such as arsenic in drinking water and aristolochic acid in Chinese herbal medicine. As more gene sequencing differences between upper tract urothelial carcinomas and various disease causes are detailed, this has warranted the era of individualized screening and treatment for the disease.

Consequences of delay in screening, monitoring, and treatment of angiomyolipoma and tuberous sclerosis: A case report
.

BACKGROUND: Tuberous sclerosis complex (TSC) is a multisystem disorder that results in tumor growth in various organs. TSC can affect the kidneys in the form of renal angiomyolipomas and cysts that can lead to chronic kidney disease. CASE PRESENTATION: A 38-year-old woman was referred to Kennedy Krieger Institute for comprehensive TSC management. Before referral, the patient had gone most of her life without a definite diagnosis of TSC despite visually-prominent signs such as forehead plaques, facial angiofibromas, and ungual fibromas. Eventually, complications of the disease led to the patient requiring hemodialysis at age 34 and a complete bilateral nephrectomy at age 36. However, the patient was not diagnosed with TSC until an evaluation at the National Institutes of Health at age 37. After becoming a patient at our clinic, a multidisciplinary approach was taken to provide comprehensive care by including various disciplines such as nephrology, neurology, pulmonology, ophthalmology, dentistry, dermatology, and cardiology. DISCUSSION AND CONCLUSION: TSC consensus recommendations aid in diagnosis, monitoring, and treatment of TSC and its associated manifestations, including those involving the kidneys. Our case underscores the importance of early identification of TSC to prevent future complications and promotes use of a multidisciplinary team to provide comprehensive care.

Association between coffee consumption and risk of renal cell carcinoma: a meta-analysis.

BACKGROUND/OBJECTIVES: The risk of renal cell carcinoma (RCC) in individuals who regularly drink coffee is controversial. Several antioxidant compounds in coffee have been proposed to reduce the risk of RCC, while the findings from several studies raise concerns regarding a potential increased risk of RCC with coffee consumption. AIM: This meta-analysis aims to evaluate the association between coffee consumption and RCC. METHODS: A literature search was performed using MEDLINE, EMBASE and Cochrane Database of Systematic Reviews from inception until December 2016. Studies that reported odd ratios or hazard ratios comparing the risk of RCC in individuals who consumed a significant amount of coffee (at least one cup of coffee per day) versus those who did not consume coffee were included. Pooled risk ratios (RR) and 95% confidence intervals (CI) were computed using a random-effect, generic inverse variance method. RESULTS: Twenty-two observational studies (16 case-control and 6 cohort studies) were included in our analysis to assess the association between RCC and coffee consumption. The pooled RR of RCC in individuals consuming coffee was 0.99 (95% CI, 0.89-1.11). Subgroup analyses stratified by gender showed pooled RRs of RCC of 1.15 (95% CI, 0.85-1.55) in females and 0.87 (95% CI, 0.72-1.04) in males. CONCLUSIONS: Our study demonstrates no significant association between coffee consumption and RCC. Thus, coffee consumption is likely not a risk factor for RCC. Whether coffee consumption has a potential role in reduced risk of RCC, particularly in men, requires further investigations.

[Interdisciplinary Recommendations for the Treatment of Metastatic Renal Cell Carcinoma]. / Interdisziplinäre Empfehlungen zur Behandlung des metastasierten Nierenzellkarzinoms .

Thanks to the use of targeted therapies, the prognosis of patients with metastatic renal cell carcinoma (mRCC) has improved significantly. A median overall survival of more than 2 years is a realistic claim. These improvements are also reflected in recent discussions about 3 and more lines of therapy.Sunitinib, pazopanib, the combination of bevacizumab and interferon alpha, and temsirolimus are approved for first-line therapy of mRCC. Sunitinib and pazopanib are also approved for second-line therapy, which, for pazopanib, is confined to the use after cytokine failure. Everolimus (after tyrosine kinase inhibitor (TKI) treatment), sorafenib (after cytokines) and axitinib (after treatment with sunitinib or cytokines) are other compounds available for second-line therapy.3 new substances have recently been approved for second-line therapy: Nivolumab, cabozantinib, and lenvatinib combined with everolimus can be used after VEGF-targeted treatment has failed. It is for the first time that targeted immunotherapy and a combination of targeted substances are available for the treatment of mRCC.There is no new insight as to an optimal sequence therapy. Study results from a phase III trial suggest that the sequences sorafenib-sunitinib and sunitinib-sorafenib are equally effective.The purpose of an interdisciplinary expert meeting on RCC was to work out joint treatment recommendations based on current data and clinical experience and to integrate them into clinical routine practice. The results are presented in this publication.

Tumoral cubilin is a predictive marker for treatment of renal cancer patients with sunitinib and sorafenib.

PURPOSE: Tyrosine kinase inhibitors like sunitinib and sorafenib are commonly used to treat metastatic renal cell cancer patients. Cubilin is a membrane protein expressed in the proximal renal tubule. Cubilin and megalin function together as endocytic receptors mediating uptake of many proteins. There is no established predictive marker for metastatic renal cell cancer patients and the purpose of the present study was to assess if cubilin can predict response to treatment with tyrosine kinase inhibitors. METHODS: Cubilin protein expression was analyzsed in tumor tissue from a cohort of patients with metastatic renal cell cancer (n = 139) using immunohistochemistry. One hundred and thirty six of the patients were treated with sunitinib or sorafenib in the first- or second-line setting. Thirty of these were censored because of toxicity leading to the termination of treatment and the remaining (n = 106) were selected for the current study. RESULTS: Fifty-three (50%) of the tumors expressed cubilin in the membrane. The median progression-free survival was 8 months in patients with cubilin expressing tumors and 4 months in the cubilin negative group. In addition, the overall survival was better for patients with cubilin positive tumors. We also found that the fraction of cubilin negative patients was significantly higher in the non-responding group (PFS ≤3 months) compared to responding patients (PFS >3 months). CONCLUSIONS: We show for the first time that tumoral expression of cubilin is a positive predictive marker for treatment of metastatic renal cell cancer patients with sunitinib and sorafenib.

Pituitary Metastasis from Renal Cell Carcinoma: Description of a Case Report.

BACKGROUND Pituitary metastasis is uncommon, breast and lung cancers being the most frequent primary tumors. Renal cell carcinoma (RCC) is a rare cause of pituitary metastases, with only a few cases described to date. CASE REPORT We report a case of a 61-year-old man who presented with a progressive deterioration of visual acuity and field associated with a bitemporal hemianopsia. Two years ago, he underwent radical right nephrectomy for a clear cell RCC (ccRCC). The biological tests showed pan-hypopituitarism and diabetes insipidus. Brain MRI revealed a large sellar tumor lesion bilaterally infiltrating the cavernous sinuses, which was surgically resected. Histology confirmed a ccRCC pituitary metastasis. The patient received post-surgical radiotherapy. Considering the presence of concomitant extra-pituitary metastases, treatment with sunitinib was started, followed by several lines of therapy with axitinib, everolimus, and sorafenib because of tumor progression. The patient also presented with a pituitary tumor recurrence, which was treated by stereotaxic radiotherapy. He died five years after the initial diagnosis of RCC and 30 months after the diagnosis of the pituitary metastasis.  CONCLUSIONS There are no standardized treatment guidelines for management of pituitary metastases. Pituitary surgery plays a role in symptom palliation, and it does not have any relevant impact on survival. Exclusive radiotherapy or stereotaxic radiotherapy could be an alternative to surgery in patients whose general condition is poor or who have concomitant extra-pituitary metastases.

Late diagnosis of primary hyperoxaluria type III.

We report the case of a 78-year-old patient with late diagnosis of hyperoxaluria type III (PH3). He developed renal failure after nephrectomy for clear cell papillary renal carcinoma and complained of recurrent urolithiasis for some 30 years, whose aetiology was never identified. Biochemical laboratory investigations of urine and urolithiasis composition revealed marked hyperoxaluria but normal concentrations of urinary glyceric and glycolic acid as well as stones of idiopathic calcium-oxalate appearance. Furthermore, the dietary survey showed excessive consumption of food supplements containing massive amounts of oxalate precursors. However, the persistence of excessive hyperoxaluria after his eating habits was changed leading us to perform molecular genetic testing. We found heterozygous mutations of the recently PH3-associated HOGA1 gene when sequencing PH genes. This is the first description of late diagnosis primary PH3 in a patient with several additional pro-lithogenic factors. This case illustrates the importance of undertaking a complete biological work-up to determine the aetiology of hyperoxaluria. This may reveal underdiagnosed primary hyperoxaluria, even in older patients.

Cytotoxicity of Mycobacterium indicus pranii on Mia-Pa-Ca2 cells

Background: MIP is a cultivable, non-pathogenic organism, which shares several antigens with Mycobacterium tuberculosis and Mycobacterium leprae. It has several proposed clinical applications. However, its cytotoxic effect on pancreatic cancer has not been documented. Hence, the study was conducted to investigate MIP induced cytotoxicity on Mia-Pa-Ca2 cells. To determine the cytotoxic potential of heat killed Mycobacterium indicus pranii (MIP) on pancreatic cancer cells in vitro along with gemcitabine & 5-fluorouracil (5-FU). Mitogen-activated protein kinase (MAPK) level was also studied post MIP treatment. Methods: Cytotoxic effect of MIP, gemcitabine and 5-FU on Mia-Pa-Ca2 cells was determined. We have analyzed extent of apoptosis using flow cytometry and changes in p38 levels, c-Jun N-terminal kinases (JNK) and extracellular signal­regulated kinase (ERK) using ELISA. Results: MIP not only exhibits cell cytotoxicity in dose dependent manner, but also enhances efficacy of gemcitabine and 5-FU when used in combination. Flow cytometry analyses reveals apoptosis of Mia-Pa-Ca2 cells post MIP treatment compared to untreated cells. MAPK pathway study using ELISA shows that p38 and JNK levels are suppressed while there is no change in ERK level. Conclusion: With these results we conclude that MIP is a cytotoxic agent. Cytotoxicity is exhibited by apoptosis. Combining MIP with gemcitabine and 5-FU shows synergistic effect (AU)

[The diagnostic and therapeutic challenges of bilateral renal oncocytosis : Illustrative case presentations and a review of the literature]. / Die bilaterale renale Onkozytose als diagnostische und therapeutische Herausforderung : Falldarstellung und Literaturreview.

Bilateral oncocytosis along with multiple tumours in both kidneys represents a very rare pathology that is accompanied by diagnostic and therapeutic challenges. We report the case of a 60-year old male patient who underwent computer tomography with incidental detection of multiple bilateral and contrast enhancing renal tumours of different size. Subsequently the patient underwent nephron-sparing tumor resection, first on the right side and 4 weeks later on the left side. The histology of all removed tumors showed evidence of pure oncocytoma. There were no postoperative complications and renal function reached a stable state within 6 months follow-up. The major challenge regarding diagnostic process and therapy of this pathology is to distinguish benign oncocytoma from chromophobe renal cell carcinoma and hybrid tumours, which can all be associated with renal oncocytosis. Because of limitations concerning imaging processes and biopsy, all patients should undergo nephron-sparing surgery as far as possible. On the other hand alternative therapies should - regarding to therapy-associated morbidity and the basically benign prognosis of oncocytoma - be well discussed to obtain informed consent. In this case report different therapy options and the international literature concerning renal oncocytosis will be discussed.

A decade of pharmacogenomics research on tyrosine kinase inhibitors in metastatic renal cell cancer: a systematic review.

OBJECTIVE: The individual response to targeted tyrosine kinase inhibitors (TKIs) in the treatment of metastatic renal cell cancer (mRCC) is highly variable. Outlined in this article are findings on potential biomarkers for TKI treatment outcome in mRCC and an evaluation of the status of clinical implementation. METHODS: Articles were selected by two independent reviewers using a systematic search in five medical databases on renal cell carcinoma, TKIs, and pharmacogenetics. RESULTS: Many researchers have focused on predictive biomarkers for treatment outcome of targeted therapies in mRCC patients. Attempts to explain differences in efficacy and toxicity of TKIs by use of genetic variants in genes related to the pharmacokinetics and pharmacodynamics of the drug have been successful. CONCLUSION: Most findings on potential biomarkers have not been validated and therefore biomarker testing to guide choice of therapy and dose in mRCC is not yet feasible.

An ectopic adreocortical adenoma of the renal sinus: a case report and literature review.

BACKGROUND: Ectopic adrenal tumors are very rare, especially in the renal sinus in adults. An unusual case of ectopic adrenal cortical adenoma in the right renal sinus is reported here. CASE PRESENTATION: This patient was a 37-year-old woman. She was admitted to our hospital for hypertension and bilateral limb weakness. Computed tomography (CT) revealed a mass in right renal sinus. It was initially considered a tumor of the renal pelvis. Further computed tomographic angiography (CTA) showed the mass to be located outside the renal pelvis. After adequate preoperative preparation (blood pressure control and serum potassium supplement), the patient underwent laparoscopic resection of retroperitoneal tumor. During the procedure, a soft tissue tumor 3.4*3.0 cm(2) in size with a golden color was found in the right renal sinus. The final immunohistochemistry examination showed an ectopic adreocortical adenoma. CONCLUSION: Ectopic adrenal tumors are rare in the renal sinus and difficult to diagnose and treat. Large and functional tumors should be treated with complete resection. The procedure is sometimes difficult for tumors located deep in the renal sinus. The decision to perform an open or minimally invasive surgery should be made according to the surgeon's experience.

Outcome of genetic evaluation of patients with kidney cancer referred for suspected hereditary cancer syndromes.

OBJECTIVE: To analyze patients with kidney cancer referred for evaluation at a high-volume genetics service at a comprehensive cancer center and identify factors associated with positive tests for hereditary cancer syndromes. METHODS: A retrospective review of patients referred to the Clinical Genetics Service at Memorial Sloan-Kettering Cancer Center was performed, and patients with a personal history of kidney cancer were identified. Patient and disease characteristics were reviewed. In all, 4 variables including age at diagnosis of kidney tumor, presence of syndromic manifestations, family history of kidney cancer, and number of primary malignancies were evaluated for association with positive test results in 2 groups: patients tested for renal cell carcinoma syndromes and Lynch syndrome. Guidance for genetic testing strategy in patients with kidney cancer is provided. RESULTS: Between 1999 and 2012, 120 patients with a history of kidney cancer were evaluated by the Clinical Genetics Service. The mean age at kidney cancer diagnosis was 52 years (interquartile range: 42-63), with 57% being women. A family history of kidney cancer was reported by 39 patients (33%). Time between diagnosis of first cancer and genetic consultation was <1 year in 54%, 2 to 5 years in 23%, and>5 years in the remaining 23%. Overall, 95 patients were tested for genetic abnormalities with 27 (28%) testing positive. Testing for renal cell carcinoma (RCC)-related syndromes was performed on 43 patients, with 13 testing positive (30%). Lynch syndrome testing was positive in 9 patients (32%) after 28 were tested. In RCC-associated syndromes, young age of diagnosis was associated with positive test results. Conversely, syndromic manifestations and increasing number of primary malignancies were associated with positive Lynch testing. CONCLUSIONS: The discovery of inherited kidney cancer syndromes has provided a unique opportunity to identify patients at increased risk for cancer. Factors associated with positive genetic testing are unique to different syndromes. These data suggest that in kidney cancer patients evaluated for hereditary cancer syndromes, young age is associated with diagnosis of RCC syndromes, whereas syndromic manifestations and multiple primaries are found in Lynch syndrome. These results, along with clinical awareness, may be useful for practicing urologists to select patients with kidney cancer to refer for genetic counseling.

Type 2 Diabetes Mellitus and Kidney Cancer Risk: A Retrospective Cohort Analysis of the National Health Insurance.

PURPOSE: To evaluate the association between incidence of any kidney cancer and type 2 diabetes mellitus. METHODS: A random sample of 1,000,000 subjects covered by the National Health Insurance was recruited. A total of 998728 people (115655 diabetes and 883073 non-diabetes) without kidney cancer at recruitment were followed from 2003 to 2005. The cumulative incidence of kidney cancer from 2003 to 2005 in diabetic patients and non-diabetic people in all ages and in age <40, 40-64, 65-74 and ≥ 75 years were calculated in the diabetic patients and the non-diabetic people, respectively. Logistic regression was used to estimate the odds ratios comparing diabetic patients to non-diabetic people in the respective age groups. Multivariable-adjusted odds ratios for kidney cancer with regards to diabetes status and diabetes duration (as a continuous variable or categorized into subgroups of non-diabetes, diabetes duration <1 year, 1-2.9 years, 3-4.9 years and ≥ 5 years) were estimated after multivariable adjustment. The multivariable-adjusted odds ratios for all baseline variables were also estimated for diabetic patients and non-diabetic people, respectively. RESULTS: The 3-year cumulative incidence of kidney cancer in the diabetic patients and the non-diabetic people was 166.9 and 33.1 per 100,000 person-years, respectively. The incidence increased with regards to increasing age in both the diabetic patients and the non-diabetic people, but a higher risk of kidney cancer for the diabetic patients compared to the non-diabetic people was consistently observed in different age groups. After multivariable adjustment, the odds ratio for diabetic patients versus non-diabetic people was 1.7 (95% confidence interval: 1.3-2.1, P<0.01). While compared to the non-diabetic people, the odds ratio (95% confidence interval) for diabetes duration <1, 1-2.9 years, 3-4.9 years and ≥ 5 years was 1.5 (0.8-2.7), 1.6 (1.0-2.4), 1.6 (1.1-2.4) and 1.7 (1.3-2.3), respectively (P-trend <0.01). Analyses conducted in the diabetic patients and the non-diabetic people, respectively, consistently showed age, nephropathy and end-stage renal disease as significant risk factors of kidney cancer. Additionally, living in metropolitan Taipei region might also be associated with a higher risk of kidney cancer in the non-diabetic people, indicating a potential link between kidney cancer and some factors related to urbanization. CONCLUSIONS: Patients with type 2 diabetes mellitus have a significantly higher risk of kidney cancer.

Thermal Ablation of Renal Tumors: Indications, Techniques and Results.

BACKGROUND: About 15,000 persons receive the diagnosis of kidney cancer in Germany every year. Surgical resection is the standard treatment for locally confined tumors, but minimally invasive thermoablative techniques are increasingly being used as well. METHODS: This article is based on publications retrieved by a selective literature search in PubMed regarding the thermoablative techniques now used in clinical practice, with particular attention to radiofrequency ablation (RFA) and cryoablation (CA). RESULTS: RFA and CA are suitable for patients who cannot undergo surgery because of comorbid illnesses or who have contralateral recurrences or a hereditary precancerous condition. The primary technical success rate of these procedures ranges from 88% to 100%. More than 95% of tumors under 3 cm in diameter can be completely ablated. Reported complication rates range from 1% to 7%. New data on long-term outcomes reveal metastasis-free survival rates of 88% to 99% five years after ablation. A major advantage of these procedures is that thermoablation does not impair renal function to any relevant extent and is thus a good option for patients with limited renal function or a single kidney. CONCLUSION: The thermoablative techniques are an important addition to the armamentarium of effective treatments for locally confined renal tumors. The guidelines of the American and European urological societies now list thermoablation with RFA or CA as an option for the treatment of small renal tumors with curative intent. Thermoablation of renal tumors has not yet been studied in randomized controlled trials; these will be needed so that the efficacy of tumor control, survival rates, complication rates, and quality of life after treatment can be reliably evaluated to provide definitive confirmation of the value of interstitial techniques.

Proteins S100A8 and S100A9 are potential biomarkers for renal cell carcinoma in the early stages: results from a proteomic study integrated with bioinformatics analysis.

In order to investigate the two members of the EF­hand Ca2+ binding protein S100 family, S100A8 and S100A9, in renal cell carcinoma (RCC), serum samples were collected from patients with RCC, transitional cell carcinoma in the kidney, benign renal masses and normal controls. The samples were analyzed by isobaric tags for relative and absolute quantification technology to identify the differential expression of S100A8 and S100A9 in the respective groups. Hierarchical clustering analysis was then conducted for the samples and the relevant selected gene. The cross­platform analysis for the external validation was performed by means of The Cancer Genome Atlas database, containing the gene/microRNA expression pattern and clinical information of patients with RCC. Immunohistochemical staining was used to verify the expression of S100A8 and S100A9 in the four groups. As a result, serum and mRNA expression levels of S100A8 and S100A9 were found to be upregulated in patients with RCC compared with the other three groups, which was consistent with the result of the upregulated expression of mRNA levels in RCC tissue. The overexpression of S100A8 and S100A9 in cancer cells was also confirmed by immunohistochemistry. In addition, bioinformatics revealed that let­7, a microRNA formerly identified as an inhibiting factor of RCC was downregulated in RCC, which contrasted with S100A8. It was also complementary to the sequence at the 3' untranslated region terminal of S100A8. Therefore, indicating that S100A8 and S100A9 may serve as biomarkers for the detection of RCC.

Efficacy and toxicity of sunitinib for non clear cell renal cell carcinoma (RCC): a systematic review of the literature.

BACKGROUND: The randomized phase III trial of sunitinib versus interferon Alfa provided level-A evidence for the use of sunitinib in advanced clear cell renal cell carcinoma (RCC). This systematic literature review aims at the evaluation of the level of evidence for the use of sunitinib monotherapy for advanced non clear cell RCC in terms of efficacy and toxicity parameters. METHODS: Eligible studies were identified using MEDLINE, Google scholar, ASCO, ESMO and the Cochrane databases. Searches were last updated on 1 June 2014. Eligible studies reported survival and/or response data for patients with non clear cell RCC receiving sunitinib monotherapy. RESULTS: four hundred and five results were obtained from the searches in MEDLINE (n=319 studies) and other databases (n=86). Twelve studies (involving 980 patients) were considered eligible and were included in the final analysis: six phase II clinical trials, one expanded access prospective trial and five retrospective analyses. Median PFS was reported in 11 studies ranging from 1.6 to 8.9 months. Median OS was reported in 9 studies ranging from 12 months to 22 months. The disease control rate (DCR) was reported in 10 studies, and it ranged from 35% to 91%. The overall response rate (ORR) was reported in 10 studies and it ranged from 0% to 36%. Frequently reported Grade 3/4 toxicities were gastrointestinal toxicities, mucocutaneous toxicities and hematologic toxicities. CONCLUSION: There is insufficient evidence (level C) to recommend sunitinib monotherapy in advanced non clear cell RCC and the available data suggests it appears less efficacious than that in advanced clear cell RCC. Further prospective and randomized studies are needed to explore alternative therapies in this setting.

Prognostic factors in renal cell carcinoma patients treated with sorafenib: results from the Czech registry.

The aim of this study was to describe the characteristics and outcomes of a large cohort of patients treated with sorafenib in clinical practice and to identify predictive factors associated with prognosis. Patient data were obtained from the national Czech registry (RenIS). Data of virtually all Czech patients receiving targeted therapies are entered into this non-interventional post-registration database. Demographics and clinical data, as well as all treatment sequences and clinical outcomes, are reported in this registry. A total of 836 patients treated with sorafenib before March 2013 were included in the analysis. Median age was 63 years and 70% were men. Most patients had received prior treatment with cytokines, sunitinib or both. Sorafenib was the first-line treatment in 15% of patients. Median overall survival and progression-free survival were 21.7 months and 7.5 months, respectively. Median overall survival and progression-free survival was 26.3 and 8.3 months, respectively, in patients receiving sorafenib as first-line therapy. Cox proportional models identified several parameters associated with poor outcome including time ≤1 year from diagnosis to first-line systemic treatment, performance status ≥2, low hemoglobin, and LDH >1.5 times the upper limit of normal. Our data demonstrate that the outcomes of real-life patients are comparable to those enrolled in clinical trials. Prognostic factors identified in the present study were consistent with previously reported models.
