[PMID: 37352082 PMCID: PMC10289483 DOI: 10.1097/md.0000000000034069] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 05/03/2023] [Accepted: 06/01/2023] [Indexed: 06/25/2023] Open
Abstract
To study the difference of clinical characteristics and prognostic factors from elderly patients with renal cell carcinoma (RCC), the statistical analysis was carried out based on the surveillance, epidemiology, and end results database. The relevant clinical information of 19,472 RCC patients from 2010 to 2015 were collected, and the differences of clinicopathological characteristics and survival rate was analyzed by log-rank method and Chi square test, respectively. Multivariate Cox regression model was used to explore the independent risk factors affecting the long-term survival of RCC patients. Results showed that the proportion of elderly RCC patients in the 60-64-year group in 2010 was 15.20%, but the value elevated to 18.51% in 2015, and the Chi-square test revealed the significant correlation between elderly RCC patients with gender, race, American Joint Committee on cancer stage, T stage, N stage, and M stage. The difference of survival time between the 60-69 year, 70-79 year, 80-84 year, and 85+ year group was significant, and Kaplan-Meier analysis showed a negative effects of age on survival rate of RCC patients, indicating a worsening trend with increasing age. Cox proportional hazards model analysis further confirmed that age was the important independent prognostic factor. Our study reveals that the onset age of RCC in elderly population is gradually decreasing, and the malignant degree of elderly RCC patients is increasing with age. The female elderly population could be more susceptible to RCC than male elderly population, and 85+ year population could also be cancer susceptible with a higher lymph node metastasis rate, later tumor stage, and poor prognosis, suggesting that these elderly populations should pay more attention to the RCC screening.

Abstract
Background The number of elderly patients with early renal cell carcinoma (RCC) is on the rise. However, there is still a lack of accurate prediction models for the prognosis of early RCC in elderly patients. It is necessary to establish a new nomogram to predict the prognosis of elderly patients with early RCC. Methods The data of patients aged above 65 years old with TNM stage I and II RCC were downloaded from the SEER database between 2010 and 2018. The patients from 2010 to 2017 were randomly assigned to the training cohort (n = 7233) and validation cohort (n = 3024). Patient data in 2018(n = 1360) was used for external validation. We used univariable and multivariable Cox regression model to evaluate independent prognostic factors and constructed a nomogram to predict the 1-, 3-, and 5-year overall survival (OS) rates of patients with early-stage RCC. Multiple parameters were used to validate the nomogram, including the consistency index (C-index), the calibration plots, the area under the receiver operator characteristics (ROC) curve, and the decision curve analysis (DCA). Results The study included a total of 11,617 elderly patients with early RCC. univariable and multivariable Cox regression analysis based on predictive variables such as age, sex, histologic type, Fuhrman grade, T stage, surgery type, tumors number, tumor size, and marriage were included to establish a nomogram. The C-index of the training cohort and validation cohort were 0.748 (95% CI: 0.760–0.736) and 0.744 (95% CI: 0.762–0.726), respectively. In the external validation cohort, C-index was 0.893 (95% CI: 0.928–0.858). The calibration plots basically coincides with the diagonal, indicating that the observed OS was almost equal to the predicted OS. It was shown in DCA that the nomogram has more important clinical significance than the traditional TNM stage. Conclusion A novel nomogram was developed to assess the prognosis of an elderly patient with early RCC and to predict prognosis and formulate treatment and follow-up strategies.

Abstract
Background: The incidence of renal cell carcinoma (RCC) in young adults has started to increase in recent years. Objectives: The objective of the study was to describe and compare the mode of presentation, incidence, risk factors, histopathological features, nephrectomy modalities used, and outcome in patients diagnosed with RCC below the age of 50. Materials and Methods: A total of 139 confirmed RCC patients diagnosed below the age of 50 years who underwent nephrectomy from January 1990 to April 2019 were included in this retrospective review. We compared the characteristics of two age groups (≤40 years and 41–50 years) and evaluated incidentally discovered versus symptomatic tumors in patients below 50 years. Results: Loin pain contributed to most symptomatic presentations in the older group (55%) (P = 0.014). Hypertension and diabetes were present in 24% of patients from 41 to 50 years of age versus 3.8% for hypertension and 5.7% for diabetes in the young group. (P = 0.001 and P = 0.004, respectively). Chromophobe was the second most common pathology (26.5%). Tumor size tended to be larger in the older group (P = 0.006). Fuhrman's grade was significantly lower in incidentally diagnosed patients (88.2%) (P = 0.006). The T stage was significantly lower in the incidental group (P = 0.005), but the mortality rate was higher in symptomatic patients (9.6%) (P = 0.013). Conclusion: RCC increases after the age of 40–50 years in the presence of other risk factors. Chromophobe represented almost a quarter percentage of the pathology, while partial nephrectomy yielded a better outcome.

Abstract
Introduction To compare complication rates in radical nephrectomy for renal cell carcinoma across different age groups. Methods Retrospective analysis of the British Association of Urological Surgeons Nephrectomy Audit database between 1st January 2012 and 31st December 2017 was performed. Comparisons were made between different age groups (<60, 60-79, ≥80) in patients undergoing radical nephrectomy for renal cell carcinoma. Results 18438 patients with renal cell carcinoma underwent radical nephrectomy: 6128 (33.2%) aged <60, 10785 (58.5%) aged 60-79 and 1525 (8.3%) aged ≥80. There was a significantly lower pre-operative haemoglobin and eGFR with advancing age (p<0.001). Patients ≥80 had a higher Charlson co-morbidity index and WHO performance status (p<0.001). There was also significant variability in the approach to RN (p<0.001): laparoscopy was most commonly performed (68.8% vs. 69.3% vs. 75.0%). Patients ≥80 years were found to have the shortest operating time (p<0.001). There were significant differences in T stage between groups with patients aged ≥80 having a higher T stage (p<0.001). The incidence of intra-operative complications did not significantly differ between age groups (p=0.18). The incidence of post-operative complications was 15.7%, 18.2% and 20.5% and major post-operative complications was 1.4%, 2.1% and 2.8% in patients <60, 60-79 and ≥80, respectively (p<0.001). The most common complication in all age groups was blood transfusion (7.6% <60, 8.6% 60-79, 9.1% ≥80). Stepwise logistic regression analysis adjusting for additional variables found the odds of a post-operative complication increased with age with an odds ratio of 1.25 in patients ≥80 and an odds ratio of 1.09 in patients aged 60-70 compared with <60. Conclusion Overall complications in all age groups are low but advancing age should be considered as an independent risk factor for post-operative complications after radical nephrectomy and should be appropriately considered when counselling elderly patients prior to treatment.

Abstract
Introduction and importance Renal cell carcinoma is the most common malignant tumor of the kidney which occurs more frequently in men and older people than in women and young adults. Renal cell carcinoma is the second most common renal malignancy diagnosed among pediatric and adolescent patients comprising of 2% to 6% of renal cancers. Case presentation A 19 years old young adult male came with a history of epigastric and back pain, hematuria and weight loss. Per abdominal examination showed a palpable mass in the epigastric and left hypochondriac region. Radiological imaging showed diffuse infiltration of renal interstitium with multiple hypodense lesions in left kidney, renal vein infiltration, and lytic destruction of vertebral bodies and left superior pubic ramus. Fine needle aspiration cytology and trucut biopsy was taken which confirmed renal cell carcinoma, clear cell type with bone metastasis. Clinical discussion Although most renal cell carcinoma is sporadic and relatively uncommon in young adults, the incidence of renal cell carcinoma in this age group has steadily increased. Young adults are less likely to receive diagnosis of renal cell carcinoma incidentally. A few reported pediatric series have shown that renal cell carcinoma is highly aggressive, tends to be invasive, and metastasizes to the lungs and bones. Conclusion Young adult with clear cell renal cell carcinoma showing wide spread metastasis is rare. Since, young age is an independent prognostic factor for cancer-specific survival, early diagnosis of the tumor will be beneficial for patients. Renal cell carcinoma with wide spread metastasis is rare in young adults. Young adults are more likely to present with symptoms. Symptomatic tumor presentations did not decreased despite modern imaging technique. Younger and generally healthier population rarely come for tumor screening.

Oncologic Outcomes in Young Adults With Kidney Cancer Treated During the Targeted Therapy Era. Clin Genitourin Cancer 2019; 18:e134-e144. [PMID: 31980410 DOI: 10.1016/j.clgc.2019.09.012] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2019] [Revised: 08/22/2019] [Accepted: 09/10/2019] [Indexed: 11/23/2022]
Abstract
BACKGROUND The objective of this study was to determine the outcomes of young adults with kidney cancer treated during the targeted therapy era and evaluate the impact of young age on survival. MATERIALS AND METHODS We reviewed the records from 445 patients younger than 55 years with kidney cancer at a single institution from 2006 to 2017. Overall survival (OS) and recurrence-free survival were estimated with the Kaplan-Meier method and log-rank test. Cox proportional hazards regression was used to determine the impact of clinical and pathologic variables on all-cause mortality. RESULTS Overall, 104 (23%) patients 40 years or younger were compared with 341 (77%) patients who were 41 to 55 years old. Younger patients presented with more advanced stages of the disease, including metastasis at diagnosis, positive lymph nodes, venous tumor thrombus and had more non-clear cell tumors (54% vs. 30%; P < .001). Young adults had significantly worse OS at 2 and 5 years (67% vs. 82% and 53% vs. 69%, respectively). Younger patients with metastatic disease received targeted agents less often compared with the older group (64% vs. 75%). There was no difference in recurrence-free survival across patients with localized disease. Independent prognostic factors associated with increased mortality were metastasis at diagnosis, pT2 or greater, and age younger than 40 years (hazard ratio, 1.65; 95% confidence interval, 1.0-2.6; P = .03). CONCLUSION Patients younger than 40 years with kidney tumors treated during the targeted therapy era have worse OS compared with older adults. Young age is an independent predictor of mortality.

Abstract
Purpose: Renal tumors are rarely seen in young adults. In this study, was aimed to report the data of 18-40 years old patients with Renal Cell Carcinoma (RCC) whom we operated. Material and Method: We retrospectively reviewed the data of patients between the ages of 18 and 40 years old patients who have renal masses. All patients were evaluated with chest X-ray, Computed tomography (CT) and/or MRI. Radical or partial nephrectomy was performed for clinical localized masses with malignancy suspicion. Clinicopathological features and survival data of all the patients were recorded. In the follow-up protocol routine blood tests, chest X-ray and abdominal CT were used. Results: A total of 42 patients, [22 (52.4%) male and 20 (47.6%) female], with a mean age of 34.48 (range 18 to 40) were included in the study. Of these, 32 (%76) had RCC and 10 (24%) had benign pathologies. Female patients had more benign pathology (35% vs 13.6%). The most commonly subtype of RCC (n = 22% 69) was clear cell RCC (cRCC), while the most common benign mass was oncocytoma (n = 4% 40). At the mean follow-up period of 42.34 months, overall survival rate was found to be 93.8%. Conclusion: Young adults with localized renal mass have benign pathology in a considerable rate. All of the malign masses in this population have low Furhman grade (1 or 2).

Abstract
Objectives The aim of this study was to establish comprehensive and practical nomograms, based on significant clinicopathological parameters, for predicting the overall survival (OS) and the disease-specific survival (DSS) of patients with clear cell renal cell carcinoma (ccRCC). Patients and methods The data of 35,151 ccRCC patients, diagnosed between 2004 and 2014, were obtained from the database of the Surveillance, Epidemiology, and End Results (SEER) program. The Kaplan–Meier method and Cox proportional hazards regression model were used to evaluate the prognostic effects of multiple clinicopathological variables on survival. Based on Cox models, a nomogram was constructed to predict the probabilities of OS and DSS for an individual patient. The predictive performance of nomograms was evaluated using the concordance index (C-index) and calibration curves. Results According to univariate and multivariate analyses, age at diagnosis, sex, race, marital status, surgical approach, tumor node metastasis (TNM) stage, and Fuhrman grade significantly correlated with the survival outcomes. These characteristics were used to establish nomograms. The nomograms showed good accuracy in predicting 3-, 5-, and 10-year OS and DSS, with a C-index of 0.79 (95% CI, 0.79–0.80) for OS and 0.87 (95% CI, 0.86–0.88) for DSS. All calibration curves revealed excellent consistency between predicted and actual survival. Conclusion Nomograms were developed to predict death from ccRCC treated with nephrectomy. These new prognostic tools could aid in improving the predictive accuracy of survival outcomes, thus leading to reasonable individualized treatment.

Abstract
Elderly individuals represent a consistent proportion of all cancer patients. However, they are under-represented in clinical trials. The present study evaluated the actual tolerability of sunitinib in elderly Japanese patients with advanced renal cell carcinoma (RCC). A total of 56 consecutive patients with advanced RCC treated with sunitinib were enrolled. Patients were divided into two groups according to their age at the time of sunitinib initiation: i) elderly cohort (≥70 years); and ii) younger cohort (<70 years). Disease control rate, progression-free survival, overall survival and relative dose intensity (RDI) were compared between the two cohorts. The elderly cohort comprised of 14 patients (25.0%), and the younger cohort included 42 patients (75.0%). The elderly cohort had a significantly higher Charlson comorbidity index than the younger cohort (mean, 9.7 vs. 7.9; P<0.0001). Disease control rate, progression-free survival, and overall survival were not significantly different. The elderly cohort had a significantly lower RDI than the younger cohort (mean, 51.7 vs. 65.0%; P=0.0340). Thus, treatment with sunitinib is feasible and effective in elderly Japanese patients with advanced RCC. However, the RDI of elderly patients was significantly lower, and a relatively low dose of sunitinib provided optimal therapeutic efficacy.

Abstract
Objective: The feasibility of curative surgery for elderly patients with renal cell carcinoma (RCC) remains controversial and under discussion. The main aim of this study was to evaluate the long-term benefits of curative surgery as a treatment for RCC in elderly patients. Methods: We retrospectively considered 672 patients with RCC who underwent partial nephrectomy or radical nephrectomy between January 2004 and July 2014. X-tile program was used to determine the optimal age cutoff values with CSS as endpoint. Results: Patients were divided into the following groups according to their age using the method of X-tile program: a young group (< 40 years), a young-old group (40-75) and an old-old group (≥ 75). Following multivariate analysis age ≥ 75 years was determined to be an independent risk factor for overall survival (HR=4.36; 95% CI: 1.31-14.48; P=0.016); interestingly, this was not the case for cancer-specific survival (HR = 2.65; 95%CI: 0.77-9.16; P=0.124). Furthermore, an age of 40 to 75 years was not a risk factor according to univariate and multivariate analysis. Conclusion: After determining the age cutoff values, there was no significant difference in prognosis between young and old patients with RCC.

Abstract
INTRODUCTION The epidemiology of kidney cancer is evolving with a net increase in the incidence of renal tumors, globally, and in young people in particular. OBJECTIVE To evaluate the incidence and clinical and pathological characteristics of sporadic renal tumors in young subjects and their risk factors. MATERIAL AND METHODS A retrospective study aimed at collecting clinical, epidemiological and anatomopathological information from the 118 patients aged 18 to 40 treated for a sporadic kidney tumor in two Parisian university hospital centers between 2003 and 2013. RESULTS Our study showed a very significant increase in the incidence of renal tumors in our 11 years of decline (P=6.10-15). The mode of discovery also seems to have evolved with a majority of tumors (67 %), due to the considerable growth of imaging in recent decades. We also showed a different pathological distribution compared to the literature with a significant increase in the number of papillary tumors (16.9 %) and chromophobes (15.2 %), in addition to a decrease in the number of carcinomas (43.2 %) as well as the appearance of a new pathological entity of particular clinical severity: renal carcinoma related to translocation Xp11.2 (15.3 %) (P<10-5). Among the risk factors, hypertension seems to be a definite risk factor while tobacco and obesity do not have a significant influence. CONCLUSION Our study showed a marked increase in the incidence of renal tumors with specific clinical and epidemiological features in a population of young subjects. The role and importance of oncogenetic management as well as the study of environmental factors could lead to the identification of new risk factors and corollary to their prevention.

Impact of Young Age at Diagnosis on Survival in Patients with Surgically Treated Renal Cell Carcinoma: a Multicenter Study. J Korean Med Sci 2016; 31:1976-1982.

Abstract
The prognostic significance of age in renal cell carcinoma (RCC) is a subject of debate. The aim of the present multi-institutional study was to evaluate the impact of age on clinicopathological features and survival in a large cohort of patients with RCC. A total of 5,178 patients who underwent surgery for RCC at eight institutions in Korea between 1999 and 2011 were categorized into three groups according to age at diagnosis as follows: young age (< 40 years, n = 541), middle-age (≥ 40 and < 60 years, n = 2,551), and old age (≥ 60 years, n = 2,096) groups. Clinicopathological variables and survival rates were compared between the three groups. Young patients had lower stage tumors with a low Fuhrman grade, a lower rate of lymphovascular invasion than patients in the other age groups. Regarding histologic type, the young age group had a lower percentage of clear cell histology and a greater incidence of Xp11.2 translocation RCC. Kaplan-Meier estimates showed that cancer-specific survival was significantly better in the young age group than in the other groups (log rank test, P = 0.008). However, age at diagnosis was not an independent predictor of survival in multivariate analysis. In conclusion, young age at diagnosis was associated with favorable pathologic features, although it was not an independent prognostic factor for survival in patients with surgically-treated RCC. Age itself should not be regarded as a crucial determinant for the treatment of RCC.

Abstract
OBJECTIVE The aim of this study was to investigate the influence of age at diagnosis on tumor characteristics and cancer-specific survival (CSS) in renal cell carcinoma (RCC). MATERIALS AND METHODS Data of patients who underwent radical or partial nephrectomy for renal tumor between 2003 and 2011 at multiple institutions were collected. Patients were divided into two groups according to age at diagnosis: 20-39 years and 40-79 years. To adjust for potential baseline confounders, propensity score matching was performed. RESULTS All included data showed that young RCC patients presented with renal tumors that had a more favorable histological subtype, were localized, smaller in size, and had a lower Fuhrman nuclear grade. The 5 year CSS rates were 95.5% and 90.5% in the young and old patient groups, respectively (log rank p = 0.019). After matching on the propensity score, the two groups with RCC had 302 patients each. Because the groups were matched on covariates, there were no significant differences in the pathological proportion, tumor size, Fuhrman nuclear grade and clinical T stage. The 5 year CSS rates were 95.5% and 94.7% in the young and old patient groups, respectively (log rank p = 0.184). CONCLUSION After adjusting for potential biases, there was no significant difference in prognosis between young and old patients with RCC.

Chromophobe Renal Cell Carcinoma is the Most Common Nonclear Renal Cell Carcinoma in Young Women: Results from the SEER Database. J Urol 2015; 195:847-51.

Abstract
PURPOSE The renal cell cancer incidence is relatively low in younger patients, encompassing 3% to 7% of all renal cell cancers. While young patients may have renal tumors due to hereditary syndromes, in some of them sporadic renal cancers develop without any family history or known genetic mutations. Our recent observations from clinical practice have led us to hypothesize that there is a difference in histological distribution in younger patients compared to the older cohort. MATERIALS AND METHODS We queried the SEER (Surveillance, Epidemiology and End Results) 18-registry database for all patients 20 years old or older who were surgically treated for renal cell carcinoma between 2001 and 2008. Patients with unknown race, grade, stage or histology and those with multiple tumors were excluded from study. Four cohorts were created by dividing patients by gender, including 1,202 females and 1,715 males younger than 40 years old, and 18,353 females and 30,891 males 40 years old or older. Chi-square analysis was used to compare histological distributions between the cohorts. RESULTS While clear cell carcinoma was still the most common renal cell cancer subtype across all genders and ages, chromophobe renal cell cancer was the most predominant type of nonclear renal cell cancer histology in young females, representing 62.3% of all nonclear cell renal cell cancers (p <0.0001). In all other groups papillary renal cell cancer remained the most common type of nonclear renal cell cancer. CONCLUSIONS It is possible that hormonal factors or specific pathway dysregulations predispose chromophobe renal cell cancer to develop in younger women. We hope that this work provides some new observations that could lead to further studies of gender and histology specific renal tumorigenesis.

Abstract
OBJECTIVE Renal neoplasms have a predilection to occur in older patients and they are often malignant. They may have different structural characteristics according to age groups. In our study, we have investigated age-related demographic characteristics of the patients who were operated because of suspected malignant renal masses. MATERIALS AND METHODS Between 2010 and 2014, 129 patients were treated surgically for suspected malignant renal masses at our institution. These cases had undergone open radical, open partial, and laparoscopic radical nephrectomies. Patients were divided into two groups based on their ages and evaluated accordingly as Group 1 (≤50 years) and Group 2 (>50 years). Groups were compared based on their clinical and pathological features. RESULTS Group 1 and Group 2 consisted of 29 (22.4%) and 91 (77.6%) patients, respectively. The mean age of younger patients was 43.1 years (23-49 years), with a male to female ratio of 19/10, while the average tumor size was 57.6 mm (20-120 mm). Twenty-four patients (83%) had a malignant pathology and five patients (17%) had a benign pathology. Clear cell carcinoma was diagnosed in 67% of the patients in both groups. There was no significant difference with respect to age and tumor size of male and female patients in the younger age group, while younger female adults tended to have a more benign pathology than their male counterparts (40% and 5%, respectively, p<0.05). CONCLUSION There was no significant difference with respect to gender, tumor size, laterality, and surgical and pathologic features between younger and older patients. An organ- sparing approach should be strongly considered when treatment for renal tumors in young females is performed because of a potentially higher incidence of a benign pathology of renal masses.

Abstract
Background: We retrospectively analyzed sunitinib outcome as a function of age in metastatic renal cell carcinoma (mRCC) patients. Methods: Data were pooled from 1059 patients in six trials. Kaplan–Meier estimates of progression-free survival (PFS) and overall survival (OS) were compared by log-rank test between patients aged <70 (n=857; 81%) and ⩾70 (n=202; 19%) years. Results: In first-line patients, median PFS was comparable in younger and older patients, 9.9 vs 11.0 months, respectively (HR, 0.89; 95% CI: 0.73–1.09; P=0.2629), as was median OS, 23.6 vs 25.6 months (HR, 0.93; 95% CI: 0.74–1.18; P=0.5442). Similarly, in cytokine-refractory patients, median PFS was 8.1 vs 8.4 months (HR, 0.79; 95% CI: 0.49–1.28; P=0.3350), while median OS was 20.2 vs 15.8 months (HR, 1.14; 95% CI: 0.73–1.79; P=0.5657). Some treatment-emergent adverse events were significantly less common in younger vs older patients, including fatigue (60% vs 69%), cough (20% vs 29%), peripheral edema (17% vs 27%), anemia (18% vs 25%), decreased appetite (13% vs 29%), and thrombocytopenia (16% vs 25% all P<0.05). Hand–foot syndrome was more common in younger patients (32% vs 24%). Conclusions: Advanced age should not be a deterrent to sunitinib therapy and elderly patients may achieve additional clinical benefit.

Abstract
Background Age at diagnosis has been shown to be an independent prognostic factor of localized renal cell carcinoma (RCC) in several studies. We used contemporary statistical methods to reevaluate the effect of age on the cancer-specific survival (CSS) of localized RCC. Methods and Findings 1,147 patients with localized RCC who underwent radical nephrectomy between 1993 and 2009 were identified in our four institutions. The association between age and CSS was estimated, and the potential threshold was identified by a univariate Cox model and by martingale residual analysis. Competing risks regression was used to identify the independent impact of age on CSS. The median age was 52 years (range, 19–84 years). The median follow-up was 61 months (range, 6–144 months) for survivors. A steep increasing smoothed martingale residual plot indicated an adverse prognostic effect of age on CSS. The age cut-off of 45 years was most predictive of CSS on univariate Cox analysis and martingale residual analysis (p = 0.005). Age ≤45 years was independently associated with a higher CSS rate in the multivariate Cox regression model (HR = 1.59, 95% CI = 1.05–2.40, p = 0.027) as well as in competing risks regression (HR = 3.60, 95% CI = 1.93–6.71, p = 0.001). Conclusions Increasing age was associated with a higher incidence of cancer-specific mortality of localized RCC. Age dichotomized at 45 years would maximize the predictive value of age on CSS, and independently predict the CSS of patients with localized RCC.

Abstract
With the continually increasing number of elderly patients and the widely distributed use of radiological imaging techniques, the number of elderly patients with incidentally discovered asymptomatic small renal tumors will increase further. Treatment options range from active surveillance, minimally invasive (ablative) techniques, to open or laparoscopic surgery including radical nephrectomy. Many studies have been published on the operative treatment of small renal tumors in the elderly; however, all are limited by the retrospective nature and the small number of cases. Chronological age per se should not be a deciding factor or even an exclusion criterion for treatment of small renal tumors. The decision for therapy should be based on the physical state (comorbidities), mental and emotional state of the patient as well as the individual psychosocial environment. The decision for surgery should be based on organ preservation, depending on the tumor size of ˂7 cm and location, whenever possible.

Abstract
PURPOSE A low absolute lymphocyte count is a likely index of poor systemic immunity that may be associated with aggressive features and inferior survival in patients with clear cell renal cell carcinoma. MATERIALS AND METHODS To determine the absolute lymphocyte count we retrospectively analyzed the preoperative blood count of 430 patients with a mean age of 60 years treated with primary surgical resection at our cancer center. Absolute lymphocyte count values as a continuous variable and at a level below 1,300 cells per μl, which was our lowest reference value, were correlated with nuclear grade, pathological stage and TNM stage. We used the Kaplan-Meier method to estimate overall survival, stratified by absolute lymphocyte count status. RESULTS As a continuous variable, low absolute lymphocyte count was associated with higher grade (p = 0.009), and higher pT stage (p = 0.034) and TNM stage (p <0.0001). Lymphopenia below 1,300 cells per μl was associated with high grade (p = 0.0043), pT stage (p = 0.051) and TNM stage (p <0.0001). At a median followup of 33.5 months lymphopenia was associated with inferior overall survival in a univariate model (p <0.0001), and on multivariate analysis independent of pT, N and M stages, patient age, grade, smoking history and comorbidities (p = 0.0102). Lymphopenia was also associated with inferior overall survival in a subset of young patients (age 60 years or less) with no distant metastasis (p = 0.014). CONCLUSIONS In 430 patients with clear cell renal cell carcinoma lymphopenia was associated with lower overall survival independent of pT and TNM stages, nuclear grade, age, tobacco smoking and comorbidity index.

Abstract
OBJECTIVES To investigate mortality rates and to comprehensively analyze prognostic indicators after radical nephrectomy for renal cell carcinoma. METHODS Data were collected from 147 patients who underwent potentially curative radical nephrectomy for renal cell carcinoma. The following data were analyzed: tumor pathology, patient demographics and clinical parameters, such as pre- and postoperative estimated glomerular filtration rate, as well as the cause of death. Cause-specific survival rates were calculated including deaths caused by renal cell carcinoma and cardiovascular disease. A Cox proportional hazard model was used for statistical analysis. RESULTS A univariate analysis showed that age at surgery (≥70 years), postoperative estimated glomerular filtration rate (<45 mL/min/1.73 m(2)), pathological high T stage, grade and venous invasion were significant poor prognostic indicators. The multivariate analysis provided evidence that pathological venous invasion was a significant poor prognostic indicator, whereas age at surgery (≥70 years), pre- (<65 mL/min/1.73 m(2)) or postoperative (<45 mL/min/1.73 m(2)) estimated glomerular filtration rate and pathological high grade were significant poor prognostic indicators in T1 tumor cases. CONCLUSIONS Post-radical nephrectomy renal function insufficiency can lead to a poor prognostic outcome, especially in patients with T1 renal cell carcinoma. Physicians should consider a comprehensive follow up focusing on possible causes of death, including those related to both renal cell carcinoma and cardiovascular disease events after radical nephrectomy.

Abstract
PURPOSE We evaluated the influence of age on gender related differences in the renal cell carcinoma presentation of patients operated on between 1995 and 2005 in a European country. We also assessed the trend of missing pathological data. MATERIALS AND METHODS Data on all patients who underwent radical or partial nephrectomy for renal cell carcinoma during 1995 to 2005 in The Netherlands were retrospectively collected from the prospective PALGA (Pathological Anatomical National Automated Archive) database. Patients were divided into 5 cohorts based on age at surgery, including 40 or less, 41 to 50, 51 to 60, 61 to 70 and greater than 70 years. Variables evaluated were gender differences by age, and tumor size, subtype, stage and Fuhrman grade. RESULTS A higher mean age in women was only observed in those older than 70 years (p <0.001). The male-to-female ratio was 2:1 at ages 41 to 60 years and 1.2:1 at greater than 70 years. Compared to men women had smaller tumors at ages 51 to 60 years (p = 0.03), stage pT3 was less common at age 41 years or greater (p = 0.02), and grade 2 was less common at age 61 years or greater (p <0.001). The incidence of tumors with missing data on stage (14.9%), subtype (52.2%) and grade (47.1%) decreased substantially during the study period (p <0.001). CONCLUSIONS Older age in women than in men who present to surgery for RCC was only prevalent in those older than 70 years. The male-to-female ratio was almost equal in patients older than 70 years compared to a 2:1 ratio at ages 41 to 60 years. Women presented with fewer pT3 tumors than men at age 41 years or greater. Missing pathological data decreased significantly between 1995 and 2005.

Abstract
BACKGROUND There is no data on the histopathological characteristics of renal tumours in young adults in Pakistan. MATERIALS AND METHODS We retrospectively analysed 133 young adults (age: 16 to ≤40 years) who underwent nephrectomy for suspected renal cancer from 1994 till July 2010. The demographical and pathological parameters were determined from original surgical biopsy reports and case files, and analysed. RESULTS The mean age of patients was 33.3 ± 6.2 years. Overall, 121 (88.9%) renal tumours were malignant, and 15 (11%) benign. Among malignant tumours, renal cell carcinoma (RCC) was predominant (100/121; 82.6%). The subtypes of RCC included: clear cell RCC, 84 (84%); papillary RCC, 11 (11%), chromophobe RCC, 3 (3%) and sarcomatoid RCC, 2 (2%). Other malignant tumours included: transitional cell carcinoma (9/121; 7.4%), primitive neuroectodermal tumour (5/121; 4.1%), synovial sarcoma (2/121; 1.6%), Non-Hodgkin's lymphoma (2/121; 1.6%), leiomyosarcoma (1/121; 0.8%), malignant fibrous histiocytoma (1/121; 0.8%) and squamous cell carcinoma (1/121; 0.8%). Among benign tumours, there were 11 cases of angiomyolipoma (11/15; 73.3%), three cases of oncocytoma (3/15; 20%) and one case of schwannoma (1/15; 6.6%). Almost two-third (62.7%) patients had stage I/II tumours, 22 (18.1%) stage III and 23 (19%) stage IV disease at the time of surgery. CONCLUSION A wide variety of renal tumours is documented in young adults with large size of the tumours and late presentation in our population.

Abstract
The term renal cell carcinoma (RCC) is used to describe a heterogeneous group of tumors that vary histologically, genetically and molecularly. Extensive research has been conducted to identify characteristics that predict outcomes among patients with RCC. In addition to histological subtype these include tumor size, patient age, mode of presentation and various hematological indices, among others. Several groups have incorporated these clinical and pathological features into nomograms which help the clinician better define individual patient prognosis and direct the optimum therapeutic approach. In the present article we review these prognostic variables and nomograms for RCC.

Abstract
Many age-associated degenerative diseases commonly involve degradation of the extracellular matrix and aberrant matrix metalloproteinase-1 (MMP-1) expression. In diverse cell lines MMP-1 or interstitial collagenase (CL) expression is tightly regulated through a network of signals involving reactive oxygen species (ROS). However, whether the in vivo age-associated increase in CL expression is also sensitive to ROS-mediated signaling has not been established. To evaluate the contribution of ROS to the age-dependent increase in CL we monitored the levels of murine CL in two well-established models of oxidant stress. Analysis of murine CL levels in mice deficient in either of the intracellular superoxide dismutases (Sod2(+/-) or Sod1(-/-)) revealed its age- and redox-dependent expression relative to WT controls. Both age- and redox-dependent increases in murine CL expression were associated with elevations in phosphorylation of the MAP Kinases, Erk, JNK and p38. CL expression was highest in renal and skeletal muscle tissue from the aged Sod1(-/-) mice and was associated with a decrease in collagen staining. These findings suggest that MAPK signaling and CL production are both age- and redox-responsive. The redox sensitivity of age-associated CL expression suggests that degenerative disease associated with aberrant matrix remodeling and oxidant stress may be amenable to antioxidant-based therapies.

Abstract
Life expectancy gradually increases in the Western part of the world. Older patients may present with small, localized tumours and/or advanced or metastatic disease and still, potentially, have a considerable life expectancy. The consequence of the increased life span is that in older patients all potential treatments have to be discussed. A critical review of the literature regarding the treatment of different stages of renal cell cancer (RCC) in the elderly patient group was conducted. Elderly people with small renal masses are up to 3.5 times more likely to have a benign lesion. The oncological outcome from nephron sparing surgery (NSS), whether by means of laparoscopy or by means of open surgery, seems not to be different between young and old patients. No relationship between local recurrence and metastatic progression rates and patient age has been demonstrated. The outcome from systemic treatments in advanced/metastatic disease has been studied, no differences were observed between age groups, although toxicity profiles might differ between the younger and older patient groups.

Abstract
PURPOSE Recent data demonstrate that age may be a significant independent prognostic variable following treatment for renal cell carcinoma. We analyzed data from the SEER (Surveillance, Epidemiology and End Results) database to evaluate the relative survival of patients treated surgically for localized renal cell carcinoma as related to tumor size and patient age. MATERIALS AND METHODS Patients in the SEER database with localized renal cell carcinoma were stratified into cohorts by age and tumor size. Three and 5-year relative survival, the ratio of observed survival in the cancer population to the expected survival of an age, sex and race matched cancer-free population, was calculated with SEER-Stat. Brown's method was used for hypothesis testing. RESULTS A total of 8,578 patients with surgically treated, localized renal cell carcinoma were identified. While 3 and 5-year survival for patients with small (less than 4 cm) renal cell carcinoma was no different from that of matched cancer-free controls, patients treated for large (greater than 7 cm) localized renal cell carcinoma experienced decreased 5-year relative survival across all age groups. Therefore, age was not a significant predictor of relative survival for patients with small (less than 4 cm) or large (greater than 7 cm) tumors. However, a statistically significant trend toward lower relative survival with increasing age was demonstrated in patients with medium size tumors (4 to 7 cm). Hypothesis testing confirmed these findings. CONCLUSIONS These data suggest that relative survival is high in patients with tumors less than 4 cm and lower in patients with tumors larger than 7 cm regardless of age. However, increasing age may be related to worse outcomes in patients with tumors 4 to 7 cm. The cause of this observation warrants further investigation.

Abstract
AbstractWe analyzed the clinicopathological features and survival rates of the patients with renal cell carcinoma younger than 50 years old. Between 2004 and 2007, 28 patients between 19–49 years underwent surgery for renal cell carcinoma. Presenting symptoms, type of the surgery performed, postoperative outcomes and duration of follow-up were recorded. Mean age was 41.5±7.6 years and 75% of patients were male. The tumor was symptomatic in 19(67.9%) and incidental in 9(32.1%) patients. Radical nephrectomy and nephron-sparing surgery were performed in 18(64.3%) and 10(35.7%) patients, respectively. The most common histologic type was clear cell(67.9%). The mean tumor diameters were 3.5±0.95 and 7.4±5.2 cm in the incidental and symptomatic groups, respectively(p=0.035). Incidentally discovered tumors and tumors treated by NSS did not include Fuhrman grade 4. There were no differences regarding pathological stage and Fuhrman grades when patients were grouped according to their symptomatology(p=0.242 and p=0.265, respectively). Overall mortality was 17.9%(n=5) whereas 4 patients(14.3%) died because of cancer. The mean survival was 30.6 months and cancer specific survival rate was 85.2%. Most of the tumors in this age group were symptomatic and most common histologic subtype was clear cell carcinoma. Incidentally discovered tumors had statistically significant lower tumor size.

Abstract
Physiologically, the lymphatic system regulates fluid volume in the interstitium and provides a conduit for immune cells to travel to lymph nodes, but pathologically, the lymphatic system serves as a primary escape route for cancer cells. Lymphatic capillaries have a thin discontinuous basement membrane, lack pericyte coverage and often contain endothelial cell gaps that can be invaded by immune cells (or tumor cells). In addition, tumor cells and stromal cells in the tumor microenvironment secrete factors that stimulate lymphangiogenesis, the growth of lymphatic endothelial cells and the sprouting of lymphatic capillaries. As a result, many tumors are surrounded by large, hyperplastic, peri-tumoral lymphatic vessels and less frequently are invaded by intra-tumoral lymphatic vessels. Carcinoma cells commonly metastasize through these lymphatic vessels to regional lymph nodes. The presence of metastatic cells in the sentinel lymph node is a prognostic indicator for many types of cancer, and the degree of dissemination determines the therapeutic course of action. Lymphangiogenesis is currently at the frontier of metastasis research. Recent strides in this field have uncovered numerous signaling pathways specific for lymphatic endothelial cells and vascular endothelial cells. This review will provide an overview of tumor lymphangiogenesis and current strategies aimed at inhibiting lymphatic metastasis. Novel therapeutic approaches that target the tumor cells as well as the vascular and lymphatic endothelial compartments are discussed.
