A systematic review and meta-analysis on the efficacy of preoperative renal artery embolization prior to radical nephrectomy for renal cell carcinoma: Is it necessary?

INTRODUCTION

Radical nephrectomy for Renal Cell Carcinoma (RCC) is still the treatment of choice for all stages except for stage I and IV, which need patient selectivity. The purpose of Renal Artery Embolization (RAE) pre-operative before radical nephrectomy is to facilitate resection, reduce bleeding, and reduce the time to surgery, but the necessity of this procedure is still debatable. This study investigates the efficacy of pre-operative Renal Artery Embolization (PRAE) before radical nephrectomy for RCC patients.

METHODS

The systematic searches based on PRISMA guidelines were conducted in Pubmed, Scopus, Web of Science, Medrxiv, and ScienceDirect databases with pre-defined keywords. Both analyses, quantitative and qualitative, were performed to assess blood loss, transfusion rate, surgical time, Intensive Care Unit (ICU) stay, and hospital stay.

RESULTS

A total of 921 patients from 8 eligible studies were included. The blood loss was significantly lower in the PRAE group compared to the control group (p = < 0.00001; SMD -20 mL; 95%CI -0.29, -0.12). There is no statistically significant difference between RAE and without RAE in the transfusion rate nephrectomy (p = 0.53, OR 0.65; 95% CI 0.16, 2.57), mean operative time (p = 0.69; SMD 5.91; 95% CI -23.25, 35.07), mean length of hospital stay (p = 0.05; SMD 0.56; 95% CI 0.00, 1.12), and mean length of stay in the ICU (p = 0.45; SMD 11.61; 95% CI -18.35, 41.57) Conclusions: PRAE before radical nephrectomy significantly reduces blood loss in RCC patients but is similar in the surgical time, transfusion rate, and length of hospital stay and ICU stay.

The relationship between urologic cancer outcomes and national Human Development Index: trend in recent years

OBJECTIVES

To describe the influence of the socioeconomic development on worldwide age-standardized incidence and mortality rates, as well as mortality-to-incidence ratio (MIR) and 5-year net survival of urologic cancer patients in recent years.

METHODS

The Human Development Index (HDI) values were obtained from the United Nations Development Programme, data on age-standardized incidence/mortality rates of prostate, bladder and kidney cancer were retrieved from the GLOBOCAN database, 5-year net survival was provided by the CONCORD-3 program. We then evaluated the association between incidence/MIR/survival and HDI, with a focus on geographic variability as well as temporal patterns during the last 6 years.

RESULTS

Urologic cancer incidence rates were positively correlated with HDIs, and MIRs were negatively correlated with HDIs. Prostate cancer survival also correlated positively with HDIs, solidly confirming the interrelation among cancer indicators and socioeconomic factors. Most countries experienced incidence decline over the most recent 6 years, and a substantial reduction in MIR was observed. Survival rates of prostate cancer have simultaneously improved.

CONCLUSION

Development has a prominent influence on urologic cancer outcomes. HDI values are significantly correlated with cancer incidence, MIR and survival rates. HDI values have risen along with increased incidence and improved outcomes of urologic caner in recent years.

Purple Sweet Potato Phytochemicals: Potential Chemo-preventive and Anticancer Activities

BACKGROUND: Purple sweet potato (PSP; Ipomoea batatas (L.) lam.) is a perennial plant from the morning glory family Convolvulaceae. This plant contains many functional compounds and a high concentration of anthocyanins and phenols, in contrast to other sweet potato plants of different colors. Both in vitro and in vivo studies have shown that parts of PSP have interesting functions in the setting of cancer. AIM: This article is a collective review of the potential properties of PSP in cancer, with an emphasis on its effects in breast, bladder, colorectal, liver, gastric, and cervical cancers.METHODS: Major English research databases, including PubMed, Web of Science, Scopus, and Google Scholar, were searched for studies evaluating the activity of PSP against cancer published ended in Mei 2020. RESULTS: The search yielded 72 articles relevant to this topic. Of note, PSP phytochemicals such anthocyanins and caffeoylquinic acid derivatives act as an antioxidant that scavenges free radicals and regulates the Keap1-Nrf2 signaling pathway, acts as an antimutagenic agent, and has anti-inflammatory activity by inhibiting activation of mitogen-activated protein kinases and the NF-κB pathway as a Chemo-preventive mechanism. Furthermore, PSP can promote apoptosis, cell cycle arrest, inhibit proliferation, cell growth inhibition, and inhibit cancer progression that actions collectively sum as anticancer activity in many cancer cells. The primary target-signaling pathway that is interfered by PSP is the phosphatidylinositol-3-kinase/protein kinase B pathway, which is a very common mutated pathway in cancer cells that regulates many physiologic processes inside the cells. CONCLUSION: As a promising medicinal plant that may serve as a Chemo-preventive and anticancer agent, further research on PSP is required to determine its clinical uses and potential as a food supplement.

Cystoscopy-assisted laparoscopic partial cystectomy for muscle-invasive bladder cancer: Initial experience in Cipto Mangunkusumo Hospital, Jakarta

INTRODUCTION

We report the experience with patients of urachal adenocarcinoma of the bladder, a rare malignancy in the urinary bladder, treated with laparoscopic partial cystectomy.

AIM

Solitary transitional cell carcinoma (TCC) of the dome/anterior wall of the bladder in some cases. As compared to radical surgery, partial cystectomy has a lower morbidity rate and similar oncological outcomes. We present our experience with laparoscopic partial cystectomy (LPC) in patients with urachal adenocarcinoma.

CASE PRESENTATION

Until being admitted to the hospital, a 60-year-old woman had been suffering from painless, sporadic gross hematuria for the previous year. Her physical examination was undistinguished. Computed tomography revealed an enhancing firmly bordered mass on the anterior-superior aspect of the bladder wall. The patient then underwent cystoscopy and laparoscopic partial cystectomy simultaneously.

CONCLUSION

Based on our first experience in LPC, we suggest that cystoscopy assisted LPC is a reasonable and safe procedure with fewer complications and does not extend the operating time. The procedure's effectiveness hinges on the patient's selection. However, many cases needed to emphasize the effectiveness and safety of LPC.

Prognostic value of platelet to lymphocyte ratio in predicting survival of patients with metastatic castration-resistant prostate cancer receiving abiraterone acetate: An evidence-based case report and review of literature

Platelet to lymphocyte ratio (PLR) is a candidate prognostic marker for metastatic castration-resistant prostate cancer patients receiving abiraterone acetate and evidence demonstrates that a high PLR is associated with poor survival. More studies are required to verify current findings and establish a definite cutoff point.

Recent advances in optical imaging technologies for the detection of bladder cancer

White-light cystoscopy (WLC) is the diagnostic standard for the detection of bladder cancer (BC). However, the detection of small papillary and subtle flat carcinoma in situ lesions is not always possible with WLC. Several adjunctive optical imaging technologies have been developed to improve BC detection and resection. Photodynamic diagnosis, which requires the administering of a photoactive substance, has a higher detection rate than WLC for the detection of BC. Narrow-band imaging provides better visualization of tumors by contrast enhancement between normal mucosa and well-vascularized lesions. A technology called confocal laser endomicroscopy can be used to obtain detailed images of tissue structure. Optical coherence tomography is a high-resolution imaging process that enables noninvasive, real-time, and high-quality tissue images. Several other optical imaging technologies are also being developed to assist with the detection of BC. In this review, we provide an overview of the strengths and weaknesses of these imaging technologies for the detection of BC.

Renal Arteries Embolization in Unresectable Clear Cell Renal Carcinoma: First Time Experience at Haji Adam Malik Hospital

OBJECTIVE

To report a case of renal arterial embolisation (RAE) in unresectable renal tumour before nephrectomy.

CASE REPORT

On presentation, the clinical features of this patient, including medical history, signs and symptoms, imaging examinations were recorded. After diagnosis and initial treatment, the result and histopathological examination were performed and discussed. We performed RAE in the unresectable renal tumour in the 28-year-old male that was complaining a palpable pain right flank mass and intermittent hematuria that had been observed five months earlier. A month after RAE, the tumour shrinks and become resectable. The parameter used was tumour volume, propulsion and component, with subjective value VAS, hematuria symptom and Quality Of Life Score EORTC-QLQ C30. The next step we performed nephrectomy with histopathology results in Clear Cell Renal Carcinoma (CCRC).

CONCLUSION

RAE is an effective therapeutic and adjuvant tool because it facilitates the dissection of unresectable large renal tumours and tumours with extensive involvement around the renal hilum; it leading to lower overall morbidity. However, the lack of randomised prospective studies is the primary reason that RAE is not used often before surgery.

Epidemiology of prostate cancer in Asian countries

The incidence of prostate cancer has been increasing worldwide in recent years. The GLOBOCAN project showed that prostate cancer was the second most frequently diagnosed cancer and the fifth leading cause of cancer mortality among men worldwide in 2012. This trend has been growing even in Asian countries, where the incidence had previously been low. However, the accuracy of data about incidence and mortality as a result of prostate cancer in some Asian countries is limited. The cause of this increasing trend is multifactorial. One possible explanation is changes in lifestyles due to more Westernized diets. The incidence is also statistically biased by the wide implementation of early detection systems and the accuracy of national cancer registration systems, which are still immature in most Asian countries. Mortality rate decreases in Australia, New Zealand and Japan since the 1990s are possibly due to the improvements in treatment and/or early detection efforts employed. However, this rate is increasing in the majority of other Asian countries. Studies of latent and incidental prostate cancer provide less biased information. The prevalence of latent and incidental prostate cancer in contemporary Japan and Korea is similar to those in Western countries, suggesting the influence of lifestyle changes on carcinogenesis. Many studies reported evidence of both congenital and acquired risk factors for carcinogenesis of prostate cancer. Recent changes in the acquired risk factors might be associated with the increasing occurrence of prostate cancer in Asian countries. This trend could continue, especially in developing Asian countries.
