ABSTRACT

Renal cell carcinoma (RCC) is the third most common malignant tumor of the genitourinary system. During disease progression, RCC can undergo local and/or distant metastasis, which seriously affects the prognosis of the patient. With the advancements in targeted therapy and immunotherapy for advanced RCC, treatment for locally advanced RCC has changed. Studies have focused on applying targeted therapy or immunotherapy in the perioperative period. This article aims to review progress on treatment of locally advanced RCC to offer references for novel treatment strategies.

ABSTRACT

Objective To evaluate the effect of the bladder scanner upon maintaining the consistency of bladder filling in cervical cancer patients during the intensity-modulated radiotherapy.Methods The bladder volume change of 20 patients diagnosed with cervical cancer throughout radiotherapy were retrospectively analyzed to determine the timing of introducing the bladder scanner. Ten patients undergoing cervical cancer radiotherapy were selected to analyze the consistency between the bladder volume measured by bladder scanner and cone-beam CT (CBCT).The changes of bladder volume before and after the intervention of bladder scanner were statistically compared. Results In total,100 CBCT images of 20 patients were retrospectively analyzed. Nonparametric test demonstrated that the bladder volume significantly differed compared with the planning volume ( P< 0. 05). Bland-Altman plot illustrated high consistency between the bladder volume measured by the bladder scanner and CBCT images with a mean difference of-6. 66 cm3 (95%CI: - 53. 1-39. 83 cm3 ). Paired-t test showed there was statistical difference between the bladder volume before intervention and the planning bladder volume (P= 0. 000).The bladder volume after intervention did not significantly differ from the planning bladder volume (P= 0. 745). Conclusions The bladder volume significantly varies throughout the treatment process. Bladder scanner should be utilized prior to treatment. The bladder volume measured by the portable bladder scanner is consistent with the planning bladder volume.

ABSTRACT

Background and purpose:The association between metabolic syndrome (MS) and renal cell carcinoma (RCC) is still unknown. The aim of this study was to elucidate how MS correlates with the prevalence and malignancy of RCC.Methods:This study enrolled 398 RCC patients (350 clear cell RCC patients, 5 XP11.2 transloca-tion RCC patients, 16 papillary RCC patients and 27 chromophobe RCC patients), 160 normal persons, and 32 benign renal tumor patients. The metabolic status of the patients was assessed, and the link between MS and the prevalence or malignancy of RCC was calculated.Results:Clear cell RCC patients had signiifcantly higher rates of hypertension, higher body mass index (BMI) and longer waist circumference. Forty-eight percent clear cell RCC patients had MS, while the number was 33% for papillary RCC, 26% for chromophobe RCC, 0% for XP11.2, 17% for AML, and 25%for normal people. MS patients had signiifcant higher rates of having clear cell RCC than no-MS patients, however this kind of difference was not seen in other types of RCC. Clear cell RCC patients with higher Furhman grade had lower rates of MS.Conclusion:Patients with MS are more likely to develop clear cell RCC. Patients with high Furhman grade tumors have low MS rates, indicating that high grade tumor may have other originating mechanisms other than metabolic disorders.

ABSTRACT

Background and purpose:Laparoscopic retroperitoneal adrenalectomy makes access to the adrenal glands easier and less invasive than open surgery. The aim of this study was to evaluate the clinical efifcacy of laparoscopic retroperitoneal adrenalectomy.Methods:A total of 130 patients who underwent retroperitoneal adrenalectomy for adrenal mass from Jan. 2007 to Dec. 2012 in Fudan University Shanghai Cancer Center were retrospectively assessed. Their clinicopathological factors, perioperative complications and short-term prognostic data were retrieved from the medical records.Results:One hundred and twenty-seven of 130 patients underwent retroperitoneal adrenalectomy successfully, and 3 patients were converted to open surgery due to severe bleeding. Among 130 patients, 63 were male and 67 were female, with the mean age 50.0 years. The pathological results of the 130 patients indicated adrenocortical adenoma in 68, pheochromocytoma in 15, medullary lipoma in 13, adrenal cysts in 10 , ganglioneuroma in 7, metastatic cancer in 5, adrenal hyperplasia in 4, schwannoma in 3, lymphangioma in 2, adrenal hematoma in 1, adrenal cortical carcinoma in 1, adrenal angiosarcoma in 1 and the deputy spleen in 1 (one patient suffering from both pheochromocytoma and ganglioneuroma). The maximum diameters were ranging from 0.5 to 9.0 cm, and mean diameter was 3.48 cm. The average blood loss in surgery was 62.73 mL. Mean length of stay in hospital was 7 d. GradeⅠ complications occurred in 5 patients, including 2 of fever, 1 of food allergy, 1 of drug allergy and 1 of hypokalemia.Conclusion: Retroperitoneal adrenalectomy should be considered as the procedure of choice for the resection of most adrenal tumors in skilled centers with the advantages of minimal invasion, increased safety and faster recovery.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the alterations in renal function after radical nephrectomy (RN) and partial nephrectomy (PN) for renal cell carcinoma (RCC) and to determine the risk factors for the onset of postoperative renal function impairment.</p><p><b>METHODS</b>We assessed the renal function of 429 T1a RCC patients by investigating the time-dependent changes of the estimated glomerular filtration rate (eGFR) after surgery from August 2003 to August 2010. Univariate and multivariate regression models were used to determine the risk factors for the onset of an eGFR < 60 ml · min⁻¹ · 1.73 m⁻² function, and to evaluate the prognosis for the two groups.</p><p><b>RESULTS</b>The mean eGFR values (ml · min⁻¹ · 1.73 m⁻²) at postoperative 1, 7 days, 1, 3, 6, 12 and 24 months were 51.4 ± 12.6, 52.1 ± 17.8, 53.2 ± 19.5, 54.6 ± 20.2, 53.8 ± 16.6, 52.7 ± 22.3 and 51.5 ± 18.4 in the RN group and 69.6 ± 18.3, 70.3 ± 19.5, 71.5 ± 21.4, 76.2 ± 22.8, 75.4 ± 19.7, 74.3 ± 16.3 and 73.1 ± 23.2 in the PN group, respectively. The eGFR of the radical nephrectomy group was significantly lower than that of the partial nephrectomy group (P < 0.05). Multivariable analysis revealed that radical nephrectomy and age were risk factors for the onset of postoperative chronic renal dysfunction.</p><p><b>CONCLUSIONS</b>Renal function recovered partially after partial and radical nephrectomy and is maintained constantly after 3 months. Surgical mode and age are risk factors for the onset of postoperative eGFR < 60 ml · min⁻¹ · 1.73 m⁻² impairment. Compared with radical nephrectomy, partial nephrectomy can preserve renal function and reduce the incidence of postoperative chronic renal dysfunction.</p>

ABSTRACT

Background and purpose:Bladder cancer radical surgery is dififcult with many perioperative complications, and the learning curve is long. To introduce the clinical application of complete retrograde radical cystectomy and consequent abdominal cavity reconstruction in male bladder cancer, and to provide a standardized surgical procedure with minimum perioperative complications and short learning curve. Methods:From Apr. 2012 to Apr. 2013, 110 cases of male patients with bladder cancer received this procedure in our department, with a median age of 64 (35-83) years;Preoperative characters, surgical parameters, perioperative complications, pathology, long-term complications and short-term prognosis were collected and analyzed. Results:The median number of lymph nodes resected in operation was 12 (8-16);Neurovascular bundles were reserved bilaterally in 65 cases, and unilaterally in 31 cases;The complete procedure including urinary diversion took 4.4 (2.2-6.0) hours, with a median time of opened abdominal cavity of 43.0 (5.0-75.0) minutes;The median blood loss was 140.0 (50.0-600.0) mL, and 4 patients needed transfusion; Median time of abdominal and pelvic drainage was 10.0 (6.0-15.0) days, the median gastrointestinal recovery time was 2.5 (1.0-12.0) days, and the median postoperative hospital stay was 17.0 (10.0-39.0) days;Grade 2 Clavien-Dindo classiifcation (CDC) of surgical complications that required medical intervention were found in 19 cases, CDC grade 3 or above were found in 8 cases;Mild to moderate postoperative ileus happened in 5 cases, all recovered in median 2 (1-4) weeks with supportive treatments;There were no perioperative deaths. All samples were sent to pathological analyses. After a median follow-up of 9 (3-15) months, no complications of or above CDC grade 3 happened, and there were no recurrence. Conclusion:Complete retrograde radical cystectomy in male bladder cancer provided clear anatomical approach, reliable neurovascular bundle preservation, less blood loss, limited abdominal organs disturbance and better surgical exposure; With respect to tumor control, more peritoneal was retained for subsequent abdominal cavity reconstruction. The introduced procedure effectively speeded up gastrointestinal recovery, reduced postoperative complications, especially the incidence of ileus and its severity, and shortened hospital stay. The learning curve of this procedure for urologists was short, and further investigation was warranted.

ABSTRACT

Background and purpose:Papillary renal cell carcinomas (PRCC) is relatively infrequent, and there are few related researches in China. This study aimed to summarize the clinical and pathological features of PRCC, and evaluate prognostic factors for patients treated with surgery.Methods:A total of 64 patients who under-went surgery for PRCC were retrospectively assessed. PRCC tissue slides from each patient were reviewed for type (ⅠorⅡ), grade, TNM stage, coagulative tumor necrosis and microvascular invasion. We estimated overall survival using the Kaplan-Meier method. Multivariate analysis was done according to the Cox proportional hazards model of factors statistically signiifcant on univariate analysis. Results:The incidence rate of ENE was 6.04%in RCC, the median age was 55 (range 22 to 78) years. The comparison of the 22 (534.4%) typeⅠPRCCs and 42 (65.6%) typeⅡPRCCs revealed that typeⅡtumors were associated with a greater stage and grade more often. The median follow-up was 46 months (range 19 to 133). Of the 64 patients, 14 died, (4.5%) with typeⅠand 13 (31.0%) with typeⅡtumors (P=0.018). The overall survival rate was 85.7%in typeⅠtumors and 55.8%in typeⅡtumors, respectively. Univariate analysis identiifed symptoms at presentation, tumor type, TNM stage and grade as prognostic factors. On multivariate analysis only metastatic RCC remained associated with decreased overall survival (HR:14.78, P=0.004). Conclusion:The per-centage of PRCC is lower and typeⅡPRCC is relatively common compared with foreign data. Metastasis at diagnosis is an independent predictive parameter of overall survival in Chinese patients with PRCC.

ABSTRACT

Background and purpose:To perform whole mount technique in the diagnosis of the prostate cancer could provide orientation to the specimen. Whole mount technique has great value in pathologic diagnosis and morphological research. However, limited by the specimen-making technique, shortage of equipment and heavy workload, this technique has not been generally accepted in China. The aim of this study was to evaluate the signiifcance of whole mount technique in the diagnosis of the prostate cancer by comparing the clinical and pathological variables between whole mount patients and conventional ones after radical prostatectomy (RP).Methods:A total number of 229 patients’ whole mount RP specimens were recruited in the study from Dec. 2012 to Feb. 2014. The control group included 393 patients’ specimens which underwent conventional sampling from Jan. 2010 to Jun. 2012. We compared the clinical and pathological variables between the groups, including age, preoperative PSA level, methods of diagnosis, preliminary diagnostic Gleason score, clinical T stage, postoperative Gleason score, pathological T stage, positive surgical margin, extraprostatic extension, seminal vesicle invasion and pelvic lymph node metastasis.Results:Two groups shared similar preoperative parameters. Also there was no signiifcant difference between the whole mount and the conventional sampling groups in postoperative Gleason score, pathological T stage, extraprostatic extension and pelvic lymph node metastasis. However, positive surgical margin and seminal vesicle invasion rates were much higher in the whole mount group than the control one and both of the differences reached statistical signiifcance (26.2%vs 17.6%, 23.1%vs 17.0%;P=0.010, 0.025)Conclusion:After compared the clinical and pathological variables, we could conclude that whole mount technique has prevalence in the diagnosis of the positive surgical margin and seminal vesicle invasion compared with the conventional sampling technique. Thus, whole mount technique should be strongly recommended in the diagnosis of prostate cancer.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the impact of androgen receptor splice variant 7 (AR-V7) expression on overall survival for patients with metastatic prostate cancer.</p><p><b>METHODS</b>The data of 113 diagnosed metastatic prostate cancer patients from January 2002 to June 2010 were collected retrospectively, including patient's age at diagnosis, prostate-specific antigen (PSA) level at diagnosis,Gleason score, clinical stage, PSA nadir during hormonal therapy, the time to PSA nadir, vital status, survival time and cause of death. The expression of AR-V7 in prostate cancer tissue was detected by using immunohistochemical staining. The correlation of AR-V7 expression and patient clinicopathological characteristics in all patients were analysed using Student t-test or Chi-square test. Cox proportional hazards regression models were used to evaluate the predictive role of AR-V7 expression and patient characteristics for overall survival.</p><p><b>RESULTS</b>The median PSA nadir was 0.7 µg/L (ranged from 0.0 to 143.0 µg/L). The median time to PSA nadir was 8.1 months (ranged from 0.9 to 71.0 months). The follow-up was performed until March 12, 2014. During the follow-up period, 67 of 113 metastatic prostate cancer patients (59.3%) died and the median overall survival was 96 months (ranged from 5 to 135 months). The AR-V7 detection rate was 20.4% (23/113). The serum PSA level in patients with positively expression of AR-V7 was significantly higher than that without AR-V7 expression (t = 2.521, P = 0.013). Multivariate Cox regression analysis indicated that the expression of AR-V7 (HR = 2.421, P = 0.002) and time to PSA nadir (HR = 1.019, P = 0.022) were independent prognostic factors of overall survival for metastatic prostate cancer patients.</p><p><b>CONCLUSIONS</b>The expression of AR-V7 in prostate cancer tissues and time to PSA nadir during hormonal therapy are independent prognostic factors of overall survival for metastatic prostate cancer patients. Therapy targeting AR-V7 may improve prognosis of metastatic prostate cancer patients.</p>

ABSTRACT

Background and purpose: Platelet to lymphocyte ratio (PLR) is an important factor reflected systematic inflammation. The clinical value of PLR has not been confirmed. The present study was to explore the value of preoperative PLR in predicting clinical stage and prognosis in upper tract urothelial carcinoma. Methods:Patients who underwent surgical therapy with postoperative pathology upper tract urothelial carcinoma without metastasis from Jan. 2007 to Mar. 2012, were collected. Following up was done by telephone and clinic work, 150 vs 1 was taken as the threshold value of PLR, and the association of PLR with tumor stage, whether suffered bladder cancer as comorbidity, recurrent or metastasis, overall survival, tumor lesion, preoperative hematuria, gender and age was analyzed. We further analyzed the association difference of disease free survival (DFS) time and overall survival (OS) time between different PLR groups. Results:Fifty-one cases of UTUC were collected, and the postoperative mean following up time is 21 (9–51) months. Twenty cases recurred or metastasis and 9 cases died. The mean DFS time was 15 (2–51) months,and the mean OS time was 21 (9–51) months. One-factor analysis of variance showed that preoperative PLR was associated with tumor stage, overall survival rate, hematuria and gender, and the P value were 0.028, 0.008, 0.045, 0.036 respectively. High PLR group was intended to be non-organ confined disease, the sensitivity was 57%and the specificity was 74%. Survival analysis by Kaplan-Meier method showed there is no statistical difference in DFS between high and low PLR groups (P=0.155). But OS time in high PLR group was significantly less than that in low PLR group (P=0.006). Cox regression confirmed that only tumor stage is an independent prognostic factor of OS (P=0.029). Conclusion:PLR has potential clinical value in predicting advanced stage disease and Cox regression confirmed that only tumor stage is an independent prognostic factor of OS.

ABSTRACT

Objective To analyze prognosic factors for patients with hormone refractory prostate cancer (HRPC) after chemotherapy of docetaxel/mitoxantrone plus prednisone and to explore the relationship between prostate specific antigen (PSA) parameters and prognosis. Methods Data from 68 patients with CRPC after chemotherapy were collected and analyzed retrospectively.The median age of these patients were 65 years old with 28 cases of biopsy Gleason score < 8 and 35 cases of ≥ 8.The median serum PSA at diagnosis,nadir and pre-chemotherapy baseline were 142 ng/ml,0.5 ng/ml and 33.0 ng/ml,respectively.There were 38 patients in docetaxel group and 30 in mitoxantrone group.PSA doubling time ( PSADT),progression free survival (PFS) and overall survival (OS) was calculated.Chi square test was used in analysis of chemotherapy effect and Cox proportional hazards regression model was applied to identify the predictors for PFS and OS.The median value of continuous variable as cutoff point was used to divide patients into two groups to compare.Risk ratio and 95% confidence interval (CI) was calculated. Results 38 (55.9%)patients experienced effective chemotherapy. The effective rate were 33% and 74% for PSADT < 1.6 months and ≥ 1.6 months group,85% and 49% for M0 and M1 stage group,and 69% and 40% for docetaxel and mitoxantrone group,(P < 0.05).The median PFS was (3.5 ± 0.5) months for all patients,which were (2.7 ±0.4) months and (5.9 ±0.6) months for patients with PSADT < 1.6 months and ≥ 1.6 months group,(5.0 ± 0.6) months and (2.7 ± 0.5 ) months for patients with docetaxel and mitoxantrone group,and (5.7 ± 0.8) months and ( 3.4 ± 0.6) months for patients with Gleason score < 8 and ≥ 8 group (P <0.05).26 case died in the end and the median OS was (28.3 ± 2.6) months for these patients,which were (15.7 ± 3.4) months and (31.6 ± 1.2) months for patients with PSADT < 1.6 months and ≥1.6 months group,(29 ± 4.1 ) months and (28 ± 3.2) months for patients with docetaxel and mitoxantrone group,and (28.7 ± 2.6) months and (24.3 ± 5.6) months for patients with Gleason score < 8 and ≥ 8 group (P < 0.05). Conclusions The effective rate of chemotherapy was related with PSADT,chemotherapy strategy and M stage.PSADT,chemotherapy strategy and Gleason score may be independent predictors for patients with HRPC taking chemotherapy.Patients with PSADT ≥ 1.6 months,docetaxel chemotherapy and Gleason score < 8 will have longer PFS and OS.

Objective To construct and evaluate a nomogram for predicting the risk of peri-operative complications after radical retro-pubic prostatectomy (RRP) with standard classification criteria.Methods The peri-operative complications and clinicopathological data of 240 patients (50-82 years old) who had undergone RRP for prostate cancer from June 2006 to June 2011 were retrospectively collected.Gleason score:95 cases < 7; 145 patients ≥ 7;Clinical staging:cT1 is 1 case (0.4%),T2a 5 cases (2.1%),T2b 7 cases (2.9%),T2c 162 cases (67.5%),T3a 26 cases (10.8%),T3b 39 cases (16.3%).The peri-operative complications (in 30 days after surgery) were classified by Clavien-Dindo Classification system (the occurrence rates are as follows:rectum injury 1.6%,wound infection 2.0%,deep venous thrombosis 1.2%,urinary leak 5.0%,lymphocele 4.5%,myocardial infarction 5.8%,second look operation 1.6%),and a logistic regression model was used to construct the nomogram.Results BMI,N staging and Blood loss more than 200ml during surgery were independent prognostic factors of RRP morbidity in multivariate logistic regression.The nomogram predicting the risk of peri-operative complications showed relative good concordance index (0.633) and good calibration. Conclusions Based on the clinicopathological factors,a nomogram to predict the probability of peri-operative complications in patients undergone RRP was constructed.This statistical tool may be beneficial in judging operation risk and help consulting with patient before or after surgery.

ABSTRACT

Objective To investigate the efficacy of Sunitinib in treating metastatic non-clear cell renal cell carcinoma (RCC).Methods Twenty-two metastatic non-clear cell subtype renal cell carcinoma patients with a median age of 46 years (29 -76 years) were treated with Sunitinib.Fourteen cases were found have metastasis post radical nephrectomy,and the remaining eight cases with metastasis received cytoreductive surgery.Pathological diagnosis showed 12 papillary RCCs,one chromophobe RCC,three collecting duct RCCs,and six unclassified RCCs.The metastatic lesions were located in the lung,lymph nodes,adrenal gland,bone,liver,and thyroid gland.The patients were given the treatment of sunitinib 50 mg qd four weeks on and two weeks off.The median time of treatment was 11 months (4.5 - 24 months).Results The objective control rate was 73%.Three papillary RCC and one chromophobe RCC reached partial remission (PR) and 12 cases maintained stable disease (SD) for more than 12 weeks.And the remaining six cases progressed (PD).Conclusions Sunitinib has definitive efficacy in metastatic papillary RCC,chromophobe RCC,collecting duct RCC and unclassified RCC.Metastatic lesions in lungs and lymph nodes might be more sensitive to Sunitinib.

ABSTRACT

Objective To evaluate the prognostic value of bilateral inguinal lymph node metastases in node-positive penile cancer. Methods Sixty patients with surgically resected node-positive penile cancer were analyzed. All the patients underwent regional lymph node dissection. Recurrence free survival curves were plotted by Kaplan-Meier method and compared by the Log-rank test. Multivariate survival analysis was performed using Cox regression model. Results Of all the patients, 18 cases had bilateral inguinal lymph node metastases. The 3-year recurrence free survival rate in patients with bilateral invovlement was significantly lower than those with unilateral disease (26.7 % vs 65.3 %, χ2 =10.6, P=0.001). In order to evaluate wether the prognostic significance of bilateral lymph node metastases was dependent of increased number of positive nodes, the two predictors were included in multivariate survival analysis.Both the number of metastatic nodes and bilateral nodal disease were independent prognostic factors (P <0.05).Comparisons of survival curves showed those patients with bilateral nodal disease and more than 2 metastatic nodes had worst outcome. Conclusion Bilateral inguinal lymph node metastases is an important prognostic factor in penile cancer irrespective of the number of positive lymph node.
