Current Status and Challenges in Rare Genitourinary Cancer Research and Future Directions.

PURPOSE OF REVIEW: In contemporary urological practice, managing rare genitourinary (GU) malignancies presents significant challenges, necessitating a comprehensive understanding of their unique characteristics and tailored treatment approaches. RECENT FINDINGS: Rare GU malignancies, whether per se, variants of common histologies, or common tumors in uncommon locations, often lack widely available clinical guidelines. Consequently, treatment decisions are frequently based on empirical evidence, risking suboptimal outcomes. However, recent advances in molecular profiling, targeted therapies, and immunotherapy offer promising avenues for improving management strategies and patient outcomes. This review provides a comprehensive overview of some rare GU malignancies encountered in clinical practice, including their distinct pathological features, current management approaches, and ongoing research directions. Understanding the complexities of these rare tumors and implementing multidisciplinary treatment strategies are essential for optimizing patient care and improving survival outcomes.

Late urinary toxicity after extreme or moderate hypofractionated prostate radiotherapy in patients with prior transurethral resection of prostate (TURP).

PURPOSE: To study the late urinary toxicity in patients with prostate cancer with prior transurethral resection of prostate (TURP) and treated with hypofractionated prostate radiotherapy. METHODS: Patients diagnosed with prostate cancer, with a prior TURP, and treated with moderate or extreme hypofractionated intensity modulated radiotherapy (MHRT or SBRT), were included in this study. Severity and duration of urinary symptoms observed during serial follow up after at least three months from radiotherapy were graded per CTCAE v5.0 using information from prospectively maintained institutional database. Impact of hypofractionation and other potential contributory factors on cumulative grade 2+ late urinary toxicity was analysed with univariable and multivariable binary logistic regression. RESULTS: Total 203 eligible patients were included (MHRT=114, 64-68Gy/25#; SBRT=89, 35-37.5Gy/5#). Median time from TURP to radiotherapy was 10 months (IQR 7-16), similar for MHRT and SBRT. Overall, mean cavity volume was 1.17cc (IQR 0.5-1.35), while in MHRT and SBRT groups was 1.03 cc (IQR 0.4-1.15) and 1.27 cc (IQR 0.5-1.4), respectively. At a median follow up of 37 months, cumulative grade 3 and grade 2 late urinary toxicity was 8.4% (n=17) and 23.2% (n=47) respectively. Grade 3 symptoms were observed at median 29 months (IQR 19-62) after radiotherapy completion, lasting for a median duration of 8 months (IQR 2-14). Hematuria (6.4%) and urinary obstruction (3.4%) were the chief grade 3 symptoms. Multivariable analysis for age, diabetes, pelvic radiotherapy, fraction size, prostate volume, TURP to radiotherapy duration, and TURP cavity volume showed no significant association with late grade 2+ urinary toxicity. CONCLUSION: In this large cohort of patients with prior TURP and treated with hypofractionated prostate radiotherapy, incidence of severe late urinary adverse effects was <10%, mainly hematuria or urinary obstruction. Most of these were temporary, and no significant contributory factors were identified for late urinary morbidity after TURP and radiotherapy.

Identification of Rare EIF3E::RSPO2 Fusion in Recurrent and Aggressive Urachal Adenocarcinoma.

INTRODUCTION: Urachal cancer (UC) is a rare genitourinary malignancy arising from the urachus, an embryonic remnant of the placental allantois. Its diagnosis remains ambiguous with late-stage cancer detection and represents a highly aggressive disease. Due to its rarity, there is no clear consensus on molecular signatures and appropriate clinical management of UC. CASE REPORT: We report a 45-year-old man with recurrent urachal adenocarcinoma (UA) treated with cystectomies, chemotherapy, and radiotherapy. The patient initially presented with hematuria and abdominal pain. Imaging revealed a nodular mass arising from the superior wall of the urinary bladder and extending to the urachus. Biopsy results suggested moderately differentiated UA with muscle layer involvement. The tumor recurred after 20 months, following which, another partial cystectomy was performed. Repeat progression was noted indicating highly aggressive disease. Targeted next-generation sequencing revealed the presence of EIF3E::RSPO2 fusion, along with BRAF and TP53 mutations, and EGFR gene amplification. This is the first case reporting the presence of this fusion in UA. Palliative medication and radiotherapy were administered to manage the disease. CONCLUSION: Current treatment modality of surgery may be effective in the early stages of recurrent UA; however, a standard chemotherapy and radiotherapy regimen is yet to be determined for advanced stages. The detection of the rare EIF3E::RSPO2 fusion warrants further studies on the significance of this variant as a possible therapeutic target for improved clinical management.

Do Uro-Oncology Day Care Procedures Need to Be Differed during COVID-19 Pandemic?-An Experience from Tertiary Cancer Care Center.

Mahendra PalBackground The SARS-CoV-2 virus pandemic has affected millions all over the world in very short span and changed the way how health care system work across the globe. It is essential to continue cancer treatment in spite of such pandemics. Various recommendations were proposed for cancer management based on risk stratification, however, in urological malignancies, day care procedures (DCPs) are a part of complete spectrum of cancer care and standard operating procedures (SOPs) for day care procedures (DCPs)in oncology is lacking at present. Materials and Methods This is an institutional review board approved retrospective observational analytical study performed in tertiary cancer care center, with aim to assess the impact of COVID-19 on Uro-oncology day care procedures (U-DCPs)in terms of changes in appointments and actual U-DCPs performed, demographic changes such as sex ratio and age wise attendance in pre and post lockdown period and to provide a SOPs to accomplishU-DCPsefficiently in pandemics. Results There was 67.89% and 68.16% reduction in total numbers of appointment and performed U-DCPs. A statistically significant difference was found in cystoscopy, intravesicalinstallation and miscellaneous UDCPs. Overall, 4.45% reduction and 4.52% increase in male and female patients underwent UDCPs respectively, M:F ratio reduced from 3.58:1 to 2.79:1 and 30% to 50% reduction in overall patient statistics in post lockdown compare to pre lockdown procedures. For various age groups there was a statistically significant change in the number for males underwent cystoscopy in (p<0.001), Intravesical therapies (p<0.001) and miscellaneous procedures(p< 0.004). Conclusion We are now coming up to the fact that effective management of healthcare system during pandemics require establishment and effective implementation of standard protocols. Routine major urological surgical care is continued using a tiered standard of protocols (SOPs) and adequate precautions. This study may provide an insight into impact of COVID-19 on UDCPs and what precautions and strategies can be institutionalized so that the patients and the health care workers remain protected from contracting infection while in performing DCPs during pandemic or similar circumstances.

Complications and Surgeon Health: Resources for individuals and institutions.

The emotional impact of surgical complications on urologists is a significant yet historically under-addressed issue. Traditionally, surgeons have been expected to cope with complications and their psychological effects in silence, perpetuating a culture of perfectionism and 'silent suffering.' This has left many unprepared to handle the emotional toll of adverse events during their training and early careers. Recognizing the gap in structured education on this matter, there is a growing movement to openly address and educate on the emotional consequences of surgical complications. This article underscores the importance of such educational initiatives in the mid-career phase, proposing strategies to promote surgeon health, and psychological safety. It advocates for utilizing Morbidity and Mortality conferences as platforms for peer support, learning from 'near miss' events, and encourages at least annual department-wide discussions to raise awareness and normalize the emotional challenges faced by surgeons. Furthermore, it highlights the role of formal peer support programs, acceptance and commitment therapy, and resilience training as vital tools for promoting surgeon well-being. Resources from various organizations, including the American Urological Association and the American Medical Association, are now available to facilitate these critical conversations. By integrating these resources and encouraging a culture of openness and support, the article suggests that the surgical community can better manage the inevitable emotional ramifications of complications, thereby fostering resilience and reducing burnout among surgeons.

Can 18 F FDG PET/CT metabolic parameters be used to noninvasively differentiate between different histopathological subtypes and Fuhrman grades of renal cell cancer?

AIM: To evaluate relationship between metabolic PET metabolic parameters and size of the primary tumor, various histopathological subtypes of renal cell carcinoma (RCC) and Fuhrman grade of the tumors. MATERIAL AND METHODS: Retrospective analysis of 93 biopsy-proven RCC patients who underwent pretreatment flourine 18 flourodeoxyglucose PET/computed tomography ( 18 F FDG PET/CT) was performed. Quantitative PET parameters, size of the primary tumor, histopathological subtypes and Fuhrman grades of the tumor were extracted. We tried to assess if there was any significant difference in the metabolic patterns of various histopathological subtypes of RCCs, Fuhrman grade of the tumors and size of the primary tumor. RESULTS: A significant correlation was noted between the size of primary tumor and maximum standardized uptake value (SUV max ), metabolic tumor volume (MTV) and total lesion glycolysis (TLG) ( P  < 0.01, P  < 0.001 and P  < 0.001, respectively). SUV max values correlated significantly with the histopathological subtype ( P  < 0.001). Further sub-analyses was also done by segregating the patients into Low grade (Fuhrman grade 1 and 2) vs. High grade (Fuhrman grade 3 and 4). SUV max , MTV and TLG were significantly different between high grade vs. low grade tumors. ROC analysis yielded cut off values for SUV max , MTV and TLG to differentiate between high grade from low grade tumors. CONCLUSION: FDG PET/CT with the use of metabolic PET parameters can differentiate between different histopathological subtypes of RCC. Incorporation of metabolic parameters into clinical practice can potentially noninvasively identify patients with low-grade vs. high-grade RCC.

Epithelioid Hemangioma of the Popliteal Artery: A Case Report.

An epithelioid hemangioma (EH) is a rare benign vascular lesion that is usually seen in superficial small vessels within the dermis and subcutaneous tissue. Intravascular epithelioid hemangiomas of large and medium-sized vessels are rare, and only a handful of cases have been reported in the literature. Intravascular epithelioid hemangiomas are biologically benign and best treated by complete surgical excision. On occasion, lesions have been associated with aneurysmal changes in the affected vessel. Local recurrence may occur, and close clinical follow-up is advised. Herein, we report the second case in the literature of an EH originating from the popliteal artery. A 57-year-old male patient presented with a one-month history of knee pain without claudication. Imaging highlighted a right popliteal aneurysm, 5x5 cm, with partial distal thrombosis and inadequate outflow. The patient subsequently underwent popliteal artery ligation above and below the aneurysm, reconstructed with a superficial femoral artery (SFA) to distal anterior tibial artery (ATA) reverse saphenous vein bypass graft. Patient recovery was complicated by the development of a 5x5 cm right-sided mid-thigh hematoma, requiring evacuation under anesthesia. A post-one-year arterial duplex of the affected limb demonstrated a recurrent enlarging popliteal aneurysm measuring 5.7x4.8x9.1 cm. The aneurysm was reported to be mostly thrombosed with noted vascularity, but patency of the original bypass was noted. The patient underwent excision of the recurrent aneurysm with subsequent ligation of the feeding arteries. Pathology and histology confirmed the final diagnosis of EH of the popliteal artery. An 18-month follow-up after the excision procedure demonstrated no recurrence of vascular lesion and patency of the original bypass graft.

Late Urinary Toxicity and Quality of Life With Pelvic Radiation Therapy for High-Risk Prostate Cancer: Dose-Effect Relations in the POP-RT Randomized Phase 3 Trial.

PURPOSE: The POP-RT phase 3 randomized trial showed improved biochemical failure-free survival and metastasis-free survival with whole pelvic radiation therapy versus prostate-only radiation therapy for high and very high-risk prostate cancer, albeit with worse RTOG late urinary toxicity. We report updated late urinary adverse effects and bladder dose-effect relations within this trial. METHODS AND MATERIALS: Late urinary toxicity and the cumulative severity of each symptom during the follow-up period were graded using the Common Terminology Criteria for Adverse Events (CTCAE), version 5.0. Bladder dosimetry in 5-Gy increments (V5, V10, V15, V65, V68Gy) in the approved radiation therapy plans was compared with urinary symptoms and overall grade 2+ toxicity. Potential factors influencing urinary toxicity were tested using multivariable logistic regression analysis. Updated urinary quality of life (QOL) scores were compared between the trial arms. RESULTS: Complete combined data for late urinary symptoms and dosimetry was available for 193 of 224 patients. At a median follow-up of 75 months, cumulative late urinary CTCAE grade 3 toxicity was low and similar for whole pelvic radiation therapy and prostate-only radiation therapy (5.2% vs 4.1%, P = .49), and grade 2 toxicity was 31.3% versus 22.7%, respectively (P = .12). Cumulative rates of each urinary symptom were similar between both arms. Multivariable analysis with age at diagnosis, known diabetes, tumor stage, trial arm, prior transurethral resection of prostate, grade 2+ acute urinary toxicity, low bladder dose (V10Gy), and moderate bladder dose (V40Gy) did not identify any significant association with late urinary toxicity. Urinary QOL scores was similar between both the arms for all the symptoms. CONCLUSIONS: During long-term follow-up, whole pelvic radiation therapy resulted in low (∼5%) and similar grade 3 cumulative urinary toxicity as prostate-only radiation therapy. The long-term patient-reported QOL scores were similar. No causative factors affecting the late urinary toxicity were identified.

Diagnostic and Surgical Implications of Non-occlusive Mesenteric Ischemic Ileus Associated With Common Celiacomesenteric Trunk: A Case Report and Literature Review.

The celiacomesenteric trunk (CMT), an exceedingly rare anatomic variant uniting the celiac artery and superior mesenteric artery (SMA), holds significant clinical and surgical implications. Despite its rarity, understanding these implications is crucial for effective management. This report outlines the case of a 99-year-old female presenting with septic shock and abdominal pain, with imaging revealing an incidental CMT. This paper aims to elucidate the surgical implications associated with CMT through a comprehensive case review and literature search. A 99-year-old female with multiple cardiovascular comorbidities presented with altered mental status and right lower quadrant abdominal pain. Upon arrival, the patient exhibited disorientation, an inability to follow commands, hypoxia, and hypotension. Significant laboratory findings included a white count of 20.6 x 109/L, lactate of 6.1 mmol/L, glucose of 53 mg/dL, alanine transaminase (ALT)/aspartate aminotransferase (AST) of 186/336 U/L, and creatinine of 4.2 mg/dL. Immediate interventions involved high-flow oxygen, fluid resuscitation, intravenous antibiotics, and admission to the ICU for septic shock. A CT angiogram (CTA) revealed an incidental large common trunk comprising the celiac trunk and superior mesenteric artery (SMA). There was a high-grade stenosis at the origin of the SMA. However, all the vessels were widely patent distally, and acute mesenteric occlusion was ruled out. By day 12, the patient achieved clinical stability after conservative management and was discharged. Complications such as aneurysm, dissection, stenosis, thrombosis, or acute occlusion of a CMT may necessitate complex surgical interventions, including endovascular procedures or open hepatic surgery. Understanding these technical complexities is vital for avoiding surgical complications in critically ill patients.

Clinical Profile and Outcomes of Carcinoma Penis Patients Receiving Systemic Therapy at an Indian tertiary care Center: A Retrospective Observational Study.

BACKGROUND: Penile cancer is a rare malignancy with scant data on the impact of systemic therapy on outcomes. METHODS: Retrospective observational study of patients with a histological diagnosis of carcinoma penis treated with systemic therapy at the Tata Memorial Centre (Mumbai, India) between August 2010 and February 2018. Primary objective was overall survival (OS); secondary objectives included assessment of clinical characteristics, treatment approaches, and toxicity profiles. RESULTS: We included 91 patients with penile carcinoma who received systemic therapy at our center. Intent of therapy was curative in 71 patients (78%), and palliative in 20 (22%). Median age was 57 years (interquartile range [IQR], 50-65.5) for curatively treated patients and 58.5 years (IQR, 44-65.2) for those with advanced disease. Common presenting symptoms were lumps (70%), and pain (57%). Neoadjuvant chemotherapy (NACT) with paclitaxel + platinum was administered to 19 patients (20.9%), of which 7 (37%) attained complete or partial response. Six patients (31.5%) underwent R0 surgery post-NACT. All 71 patients underwent primary surgery; 47 (66.2%) undergoing partial penectomy. Of the 20 patients treated with palliative first-line chemotherapy, 4(20%) attained a partial response. Median OS of patients treated in curative and palliative settings was 33.8 months (95% CI, 17.2-not recorded) and 11.4 months (95% CI, 9.53-23.3), respectively. CONCLUSIONS: Patients with penile cancer treated with systemic therapy have poor outcomes. Little over a third of the patients respond to neoadjuvant chemotherapy and those with advanced disease have poor survival despite systemic therapy, emphasizing the need for early detection and optimum management of primary and nodal disease.

Prognostic Significance of Lymph Node Density in Pathological Node Positive Urothelial Carcinoma of the Bladder -Upfront Surgery and Post Neoadjuvant Chemotherapy Cohorts.

AIM: To validate the role of lymph node density as a prognostic marker in patients undergoing primary surgery and postneoadjuvant therapy in pathological node-positive urothelial bladder carcinoma. MATERIALS AND METHODS: Retrospective analysis of 503 patients who underwent radical cystectomy from 2006 to 2019 for muscle-invasive urothelial bladder carcinoma, of which 152 patients with pathological node-positive disease were analyzed. Demographic details, pathological findings, treatment details, disease-free, and overall survival were documented. X tile program analysis was used to divide patients with positive lymph nodes into 3 groups: LD1: <= 7, LD2 :>7 to <15, LD3: >15, and the optimal cut-off value obtained was 15%. To evaluate the impact of lymph node ratio, patients with positive lymph nodes into 3 categories for each cut-off point estimation method, the application generates the histogram, Kaplan-Meier plot and calculates hazard ratio, confidence intervals and P-values. Univariate and multivariate cox regression analysis was done with a P-value of <.05, considered significant. RESULTS: One hundred fifty-two patients (30.2%) had pathological nodal metastasis, with 87 of them having perinodal extension. Ninety-six underwent primary surgery, and 56 were postneoadjuvant chemotherapy. The median follow-up was 55.42 months. 68 of the 152 node-positive patients died of the disease. Median number of lymph nodes removed was 17.11. Lymph node density divided into tertiles were LD1 <7%, LD2 7-<15%, LD3 >15% showed 5-year RFS 40.5%,29.3%, 22.6% and 5 year OS was 55.5%, 42.4%,32.1% respectively. Cox regression analysis showed that age less than 55 years ,higher tumor stage, lymphovascular invasion, and higher lymph node ratio were significant in univariate and multivariate analysis. The lymph node density cut-off value of 15% was substantial among node-positive patients (P = .027), and subgroup analysis in upfront surgery with the adjuvant treatment group and postneoadjuvant chemotherapy group was also significant (P =.021). CONCLUSION: Pathological higher T stage, Age <55 years, Lymphovascular invasion, adjuvant chemotherapy , adjuvant radiation treatment and lymph node density had prognostic significance in both cohorts of patients who underwent upfront surgery and neoadjuvant chemotherapy. Lymph node density cut-off value of <15% was prognostically significant.

A Complicated Case of Strangulated Inguinal Hernia of the Sigmoid Colon With Secondary Ischemic-Compromise of Scrotal Tissue: A Multi-Disciplinary Surgical Approach.

Inguinal hernia is amongst the most common acute abdominal disease that presents in the Emergency Department (ED). Pathologically, it involves the displacement and herniation of abdominal, pelvic, or groin tissue through weaknesses in the abdominal wall. Many inguinal hernias are simple and asymptomatic, managed conservatively without the need for surgical intervention. However, under rare circumstances, hernias are susceptible to significant complications requiring emergent surgery. This report follows the case of a 61-year-old Hispanic-American male presenting to the ED with signs of a complex strangulated inguinal hernia and consequent infarction of the testis with Fournier's Gangrene. Clinical evaluation elucidated a one-week worsening abdominal pain, non-reducible painful inguinal hernia, nausea, vomiting, constipation, groin discoloration, dysuria, and a history of failed primary hernia repair during childhood. The patient underwent emergent surgery to excise ischemic-necrotic portions of the sigmoid colon, creation of end-colostomy, non-mesh repair of inguinal hernia, and right-sided complete orchiectomy with the removal of adjacent scrotal-Dartos tissues and spermatic cord due to Fournier's Gangrene. This report provides both a report for a potentially preventable consequence in one of the most common surgical presentations and a review of the multi-disciplinary expertise that is required in the surgical management of complex inguinal hernias.

Evaluation of post-chemotherapy residual seminomatous masses by 18F-fluorodeoxyglucose PET/CT using tumor-to-liver ratio - conundrum or solution?

OBJECTIVE: Assessment of diagnostic accuracy of FDG-PET/CT in the detection of viable disease in post-chemotherapy seminomatous residual masses using visual interpretation, SUVmax, and T/L ratio. METHODS: This is a retrospective study assessing the post-chemotherapy seminomatous residual masses of size >3 cm. The PET/CT scan findings were interpreted visually for presence of residual disease which were validated from histopathology reports or imaging follow-up for a maximum of 3 years. SUVmax and T/L ratios were also determined for all the residual lesions. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value NPV were calculated and compared for all three parameters along with ROC analysis to obtain an optimal cutoff value for SUVmax and T/L ratio, respectively. RESULTS: Sample size was 49. Out of these 49 patients, 8 had validation of PET results with histopathology. Rest was validated with imaging follow-up. FDG-PET was positive in 30 patients and negative in 19 patients by visual interpretation. The sensitivity, specificity, PPV, and NPV by this method were 100%, 62.5%, 73%, and 100%, respectively. The SUVmax and T/L ratios were also calculated for these lesions. The cutoff for these two variables was 4.56 and 1.21, respectively. The sensitivity, specificity, PPV, and NPV at these cutoffs were 76%, 87.5%, 86%, 77.7%, and 92%, 87.5%, 88%, 91%, respectively. CONCLUSION: FDG-PET has a favorable diagnostic value in predicting viable disease in post-chemotherapy seminomatous residual masses and using T/L ratio cutoff of 1.21 will increase the specificity of the test.

Surgical templates for inguinal lymph node dissection in cN0 penile cancer: A comparative study.

PURPOSE: Modified and superficial inguinal lymph node dissection (MILD and SILD) are the 2 widely used templates for surgical staging of clinically node negative (cN0) penile cancer (PeCa); however, no previous reports have compared their outcomes. We compared these 2 surgical templates for oncological outcomes and complications. MATERIALS AND METHODS: We retrospectively reviewed records of cN0 PeCa patients who underwent MILD/SILD at our cancer care center from January 2013 to December 2019. Patients who developed a penile recurrence during follow up were excluded from analysis of oncological outcomes. The 2 groups (MILD and SILD) were compared for baseline clinico-pathological characteristics. The primary outcome was the groin recurrence free survival (gRFS). Secondary outcomes included the false negative rate (FNR) and disease free survival (DFS) for both templates and also the post-operative wound related complication. RESULTS: Of the 146 patients with intermediate and high risk N0 PeCa, 74 (50.7%) and 72 (49.3%) underwent MILD and SILD respectively. The 2 groups were comparable with regards to the distribution of T stage, tumor grade and the proportion of intermediate and high-risk patients. At a median follow up of 34 months (47 for SILD and 23 for MILD), a total of 5 groin recurrences were encountered; all of them occurred in the MILD group. The gRFS and DFS for the MILD group was 93.2% and 91.8% respectively; while that for the SILD group was 100% and 94.4% respectively. Too few events had occurred to determine any statistically significant difference. The FNR for MILD and SILD was 26.3% and 0% respectively. The overall complication rate was significantly higher in the SILD group (46% vs 20.3%, p=0.001), especially for Clavien Dindo 3A complications. CONCLUSION: MILD can fail to pick up micro-metastatic disease in a small proportion of cN0 PeCa patients, while SILD provides better oncological clearance with no groin recurrences. This oncological superiority comes at the cost of a higher incidence of wound-related complications.

Patterns of Utilization and Outcomes of Perioperative Chemotherapy in Patients With Locally Advanced-urothelial Bladder Cancer (LABC)-Real World Data From an Indian Tertiary Care Cancer Center.

AIM: Optimal utilization of perioperative systemic therapy in locally advanced bladder cancer (LABC) holds the key in improving the survival outcomes. We aim to analyze the oncological outcomes of clinically locally advanced urothelial bladder cancer patients treated with neoadjuvant (NACT) or adjuvant chemotherapy or without any systemic therapy in the perioperative period of radical cystectomy. METHODS & MATERIAL: We retrospectively analyzed the medical records of patients with cancer of the urinary bladder diagnosed between 2012 and 2020. The demographic profile, and the treatment received, was recorded for all patients. Oncological outcomes of the patients based on these variables were analyzed. RESULTS: Two hundred and twenty nine (229) locally advanced bladder cancer patients were included in the study. Eighty eight (38%) of them underwent upfront radical cystectomy and 141 (62%) received neoadjuvant chemotherapy (NACT). With a median follow-up of 27 months, the 2-year DFS in either of the groups was 65.4% and 67.1% respectively (P - 0.373). In the multivariate analysis, the pathological lymph nodal status and lymph vascular invasion (LVI) status influenced the DFS. The initial modality of management chosen did not affect the outcome. (HR - 0.688; 95% CI: 0.38-1.21). The commonest reason for not receiving NACT was Cisplatin ineligibility due to malignant obstructive uropathy and a subgroup analysis of this set of patients also did not show any significant difference in 2 year DFS compared to those who received NACT. CONCLUSION: A significant proportion of patients with LABC are unable to receive the recommended neoadjuvant chemotherapy and obstructive uropathy is the commonest reason for this in our centre. In our single centre series upfront radical cystectomy followed by adjuvant platinum based therapy had an outcome similar to neoadjuvant chemotherapy in LABC patients, in patients who were unable to receive the same due to various reasons.

Management of testicular tumours in patients with undescended testes- a challenging but rewarding task: experience from a tertiary care cancer centre in India.

Objective: Primary objective: To study patients' clinical profile and outcomes with germ cell tumours developing in undescended testes. Materials and methods: Case records of patients enlisted in the prospectively maintained 'testicular cancer database' at our tertiary cancer care hospital from 2014 to 2019 were retrospectively reviewed. Any patient who presented with testicular germ cell tumour with a documented history/diagnosis of undescended testes, whether surgically corrected or not, was considered for this study. The patients were managed along the standard lines of treatment for testicular cancer. We evaluated clinical features, difficulties and delays in diagnosis and complexities in management. We evaluated event-free survival (EFS) and overall survival (OS) using the Kaplan-Meier Method. Results: Fifty-four patients were identified from our database. The mean age was 32.4 years (median age 32, range: 15-56 years). Seventeen (31.4%) had developed cancer in orchidopexy testes, and 37 (68.6%) presented with testicular cancer in uncorrected cryptorchid testes. The median age at orchidopexy was 13.5 years (range: 2-32 years). The median time from symptom onset to diagnosis was 2 months (1-36 months). There was a delay in the initiation of treatment of more than 1 month in 13 patients, with the longest delay being 4 months. Two patients were initially misdiagnosed as gastrointestinal tumours. Thirty-two (59.25%) patients had seminoma, and 22 (40.7%) patients had non-seminomatous germ cell tumours (NSGCT). Nineteen patients had metastatic disease at presentation. Thirty (55.5%) patients underwent orchidectomy upfront while in 22 (40.7%) patients, orchidectomy was done after chemotherapy. The surgical approach included high inguinal orchidectomy, exploratory laparotomy or laparoscopic surgery per the clinical situation. Post-operative chemotherapy was offered as clinically indicated. At a median follow-up of 66 months (95% CI: 51-76), there were four relapses (all NSGCT) and one death. The 5-year EFS was 90.7% (95% CI: 82.9-98.7). The 5-year OS was 96.3% (95% CI: 91.2-100). Conclusions: The tumours in undescended testes, particularly those without prior orchiopexy, often presented late and with bulky masses, requiring complex multidisciplinary management. Despite the complexity and challenges, our patient's OS and EFS matched that of patients with tumours in normally descended testes. Orchiopexy may help in earlier detection. In the first such series from India, we show that testicular tumours in the cryptorchid are also as curable as the germ cell tumours developing in the descended testis.A multidisciplinary disease management group with expertise in managing complex cases is crucial for a favourable outcome in these groups of patients. We also found that orchiopexy done even later in life confers an advantage in terms of early detection in a subsequently developing testicular tumour.

Variations in Penile Cancer Management: Results From the Global Society of Rare Genitourinary Tumors Survey.

INTRODUCTION: There is paucity of evidence and consensus on various aspects of management of penile cancer (PeCa), which is intuitive considering the rarity of this disease. We present here the details of an online survey conducted by the Global Society of Rare Genito-urinary Tumors (GSRGT) with the aim of capturing the variations in PeCa care across different regions of the world. MATERIALS AND METHODS: An online questionnaire was developed by experts within the GSRGT and then circulated via email in English and Spanish versions to clinicians dealing with PeCa. Respondents were allowed 8 weeks to reply. RESULTS: We received 102 responses; the majority of them were from South America (37.2%) followed by North America and Asia (17.6% each). Only 11.7% of the respondents treated more than 25 patients with PeCa annually. Total penectomy is performed by 21.5% of the respondents in >50% of their patients. Less than a fifth of the experts (19.6%) responded that >50% of their patients are clinically node-negative (cN0) at presentation. For intermediate-risk cN0 patients (T1 G2 cancer), about a third of the experts chose surveillance. For invasive inguinal staging, the options of Dynamic Sentinel Lymph Node Biopsy (DSNB), Modified Inguinal Lymph Node Dissection (MILD), Superficial Inguinal Lymph Node Dissection (SILD), and Video-Endoscopic Inguinal Lymphadenectomy (VEIL) were chosen by 28.4%, 26.4%, 31.3%, and 13.7% of the respondents respectively. Considerable variation was seen in the worldwide use of these techniques. For clinically node-positive patients, respondents were in favor of giving adjuvant chemotherapy instead of neoadjuvant chemotherapy, except for cN3 patients. CONCLUSION: The results of this questionnaire objectified the variations in global practices in the management of PeCa. This serves as the baseline information which can help prioritize research areas for multinational collaborative efforts, a key mission of the GSRGT.

Plasmacytoid urothelial carcinoma - A clinicopathological case series of an aggressive variant of urothelial cancer.

Background: Many new morphological variants of urothelial carcinoma of urinary bladder have been described in the literature, plasmacytoid/signet ring cell/diffuse variant being one of the rare amongst these. Till date, no case series has been reported from India, describing this variant. Materials and Methods: We retrospectively analyzed the clinicopathological data of 14 patients diagnosed at our center with plasmacytoid urothelial carcinoma. Results: Seven cases (50%) were pure forms while the remaining 50% of cases had a concurrent conventional urothelial carcinoma component. Immunohistochemistry was performed to rule out other mimickers of this variant. Treatment-related data were available for seven patients, while follow-up was available for nine cases. Conclusion: Overall, plasmacytoid variant of urothelial carcinoma is considered to be an aggressive tumor with poor prognosis.

Utilising alternative cystoscopic schedules to minimise cost and patient burden after trimodality therapy for muscle-invasive bladder cancer.

BACKGROUND: To assess urinary symptoms and urine cytology as screening tools for cystoscopic detection of local recurrence after bladder-preserving trimodality treatment (TMT). METHODS: Patients with muscle-invasive bladder cancer receiving definitive TMT follow-up three monthly for 2 years, six monthly for the next 3 years and then yearly, with a clinical review, urine cytology and cystoscopy at each visit (triple assessment, TA). Grade 2+ cystitis/haematuria absent/present was scored 0/1, and urine cytology reported negative/suspicious or positive was scored 0/1, respectively. The performance of these two parameters for predicting local recurrence in cystoscopic biopsy was tested. Other hypothetical surveillance schedules included cystoscopy on alternate visits (COAV), or suspected recurrence (COSR), six-monthly COSR and six-monthly TA. RESULTS: A total of 630 follow-up visits in 112 patients with 19 recurrences (7 muscle invasive, 12 non-muscle invasive) at a median follow-up of 19 months were analysed. The sensitivity and specificity of clinical symptoms were 47.4% and 92%, and for urine cytology 58% and 85%, respectively. The combination of clinical symptoms and cytology (COSR) was 95% sensitive and 78% specific for local recurrence but 100% sensitive for muscle-invasive recurrence. Both COAV and COSV schedules showed a high area under the curve (AUC) for detecting local recurrence (COAV = 0.84, COSR = 0.83), muscle-invasive recurrence (AUC = 0.848 each) and non-muscle-invasive recurrence (COAV = 0.82, COSR = 0.81); reducing the need for TAs by 64% and 67% respectively, and overall cost by 18% and 33%, respectively. CONCLUSION: Cystoscopy at suspected recurrence during follow-up is safe and the most cost-effective for detecting muscle-invasive local recurrences, while cystoscopy at alternate visits may be more optimal for detecting any local recurrence.
