ABSTRACT
Inflammation is widely acknowledged as a significant characteristic of cancer, playing a substantial function in both the initiation and advancement of cancers. In this research, we planned to compare pan-immune inflammation markers and other well-known markers (systemic immune inflammation index and neutrophil to lymphocyte ratio) to predict prognosis in individuals treated with radical cystectomy for bladder cancer. METHODS: In this retrospective analysis, we focused on preoperative PIV, systemic immune inflammation index (SII), and neutrophil-lymphocyte ratio (NLR) in 193 individuals managed with radical cystectomy for bladder cancer between January 2016 and November 2022. Multivariable logistic regression assessments were performed to assess the predictive capabilities of PIV, SII, and NLR for infiltration of lymph nodes (N), aggressive tumor stage (pT3/pT4), and any non-organ limited disease at the time of RC. Multivariable Cox regression analyses were conducted to assess the predictive impact of PIV on Relapse-free survival (RFS), Cancer-specific survival (CSS), and Overall survival (OS). RESULTS: Our individuals were divided into high PIV and low PIV cohorts using the optimal cut-off value (340.96 × 109/L) based on receiver operating characteristic curve analysis for relapse-free survival. In multivariable preoperative logistic regression models, only SII and PIV correlated with the infiltration of lymph nodes, aggressive disease, and any non-organ confined disease. In multivariable Cox regression models considering presurgical clinicopathological variables, a higher PIV was associated with diminished RFS (p = 0.017) and OS (p = 0.029). In addition, in multivariable Cox regression models for postoperative outcomes, a high PIV correlated with both RFS (p = 0.034) and OS (p = 0.048). CONCLUSIONS: Our study suggests that PIV and SII are two very similar markers that may serve as independent and significant predictors of aggressive disease and worse survival impacts on individuals undergoing radical cystectomy for bladder neoplasm.
ABSTRACT
Hem-o-Lok clips (HOLCs) are a useful tool in mini-invasive surgery, especially for renal surgery. However, in rare cases, they could migrate into the collecting system and be calculogenic. We present a case of a 53 years old man with an incidental CT finding of a left staghorn caliceal stone increasing its size in the last 2 years. He had a medical history of ipsilateral robotic partial nephrectomy (RAPN) at another institution 8 years before and a previous renal colic with spontaneous stone elimination about 20 years before. The stone was located in the upper calyx. He underwent a flexible ureteroscopy. After an initial fragmentation, a Hem-o-lok was reported, partially wedged into the renal parenchyma. After removing the HOLC with a basket, a small urinary leak was observed and managed with a JJ stent placement. In the postoperative period, the patient had a fever managed with antibiotics and was discharged on the 4th postoperative day without problems. HOLC migration into the collecting system is a rare complication following robotic and laparoscopic renal surgery. HOLC could act as a nidus for stone formation. Avoiding too much tension during renal sutures using HOLC could reduce the possibility of migration. Simple knotting in particular conditions is a valuable option. However, this kind of stone can be managed endoscopically without complaints, minding the possibility that HOLC could be partially wedged into renal parenchyma leading to a urinary leak. With the widening indications for RAPN this kind of complication could be more frequent.
ABSTRACT
The treatment of renal cancer has changed in the last decades with an increase in application of conservative surgery such as partial nephrectomy (PN) in order to achieve an optimal oncological outcome with the maximum preservation of renal function. The indication for PN is mandatory in case of bilateral tumors or in case of impaired renal function. Renal artery (RA) aneurysm (RAA) is a rare occurrence, and its treatment could be radiological or surgical according to the anatomy of the aneurysm and the clinical characteristics of the patients. Here, we report a case of simultaneous ipsilateral occurrence of renal cancer and RAA in a patient with bilateral renal masses, treated with 1 surgical procedure with good functional and oncological outcomes. This rare occurrence must be known by surgeons treating renal cancers, and it is possible to perform the 2 procedures in 1 surgical step.
