Introduction: The literature on studies reporting trifecta or pentafecta outcomes following robot-assisted partial nephrectomy (RAPN) in Indian patients is limited. The primary aim of this study was to report and evaluate the factors predicting trifecta and pentafecta outcomes following RAPN in Indian patients using the multicentric Vattikuti collective quality initiative (VCQI) database. Methods: From the VCQI database for patients who underwent RAPN, data for Indian patients were extracted and analyzed for factors predicting the achievement of trifecta and pentafecta following RAPN. Trifecta was defined as the absence of complications, negative surgical margins, and warm ischemia period shorter than 25 min or zero ischemia. Pentafecta covers all the trifecta criteria as well as >90% preservation of estimated glomerular filtration rate (eGFR) and no stage upgrade of chronic kidney disease at 12 months. Results: In this study, among 614 patients, the trifecta was achieved in 374 patients (60.9%) and pentafecta was achieved in 24.2% of the patients. Patients who achieved trifecta had significantly higher mean age (54.1 vs. 51.0 years, P = 0.005), body mass index (BMI) (26.7 vs. 26.03 kg/m2, P = 0.022), and smaller tumor size (38.6 vs. 41.4 mm, P = 0.028). The preoperative eGFR (84.2 vs. 91.9 ml/min, P = 0.012) and renal nephrometry score (RNS) (6.96 vs. 7.87, P ≤ 0.0001) were significantly lower in the trifecta group. Comparing patients who achieved pentafecta to those who did not, we noted a statistically significant difference between the two groups for tumor size (36.1 vs. 41.5 mm, P = 0.017) and RNS (6.6 vs. 7.7, P = 0.0001). On multivariate analysis, BMI and RNS were associated with trifecta outcomes. Similarly, only RNS was identified as an independent predictor of pentafecta. Conclusions: RNS and BMI were independent predictors of the trifecta. At the same time, RNS was identified as an independent predictor of pentafecta following RAPN.

Introduction: Outcomes of robot-assisted partial nephrectomy (RAPN) depend on tumor complexity, surgeon experience and patient profile among other variables. We aimed to study the perioperative outcomes of RAPN for patients with complex renal masses using the Vattikuti Collective Quality Initiative (VCQI) database that allowed evaluation of multinational data. Methods: From the VCQI, we extracted data for all the patients who underwent RAPN with preoperative aspects and dimensions used for an anatomical (PADUA) score of ≥10. Multivariate logistic regression was conducted to ascertain predictors of trifecta (absence of complications, negative surgical margins, and warm ischemia times [WIT]

Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is a rare adnexal tumor with a predilection for the skin of the eyelid. It has also been reported in other areas of the face. Extra facial location has rarely been reported. They are twice as common in the females as compared to men and frequently affect the elderly between 50 and 80 years of age. It is a low-grade carcinoma with no reported cases of metastases, although a few cases with recurrences have been reported. Since it was first described by Flieder et al. in 1997, fewer than 60 cases have been reported in the literature. We describe one such case of EMPSGC in an adult male occurring at an unusual location, the peno-scrotal junction with systemic metastases to bilateral inguinal and iliac lymph nodes, multiple bones, and pancreas. Unlike previously reported cases, our patient worsened rapidly and succumbed to the disease six months after initiation of chemotherapy and radiotherapy. To the best of our knowledge, this is the first reported case of its kind in modern published literature.

Warthin tumor is a well-recognized benign salivary gland neoplasm consisting of an epithelial as well as a lymphoid component. Malignant transformation in Warthin tumor is rare and its reported incidence is up to 1%. The more common types of carcinomas described in Warthin tumor are the squamous and mucoepidermoid types, with high-grade adenocarcinoma being extremely rare. A high-grade adenocarcinoma (ductal type) arising in the Warthin tumor in a 72-year-old man is presented for its rarity and diagnostic difficulties.

Aim: Immature teratoma (IT) of the ovary represents 1% of all ovarian cancers and 20% of malignant ovarian germ cell tumors. This retrospective study of 28 such cases aims to look at its morphological spectrum and to study the correlation of the grade and stage of the tumor with prognosis. Materials and Methods: A retrospective study of 28 cases of IT of the ovary was done. Neuroepithelium was graded as grade I, II and III according to the standard criteria. The presence of immature mesenchyme was also looked for and similarly graded. Results: The median age for the cases was 19 years and abdominal pain was the commonest symptom. Neuroepithelium was seen in 26 cases (6 were grade I, 13 were grade II, and 7 were grade III); and two showed immature mesenchymal tissue (IM) only. IM was seen in all 28 cases, but no correlation with the grade of the IT of the ovary is found. The follow up is available in 23 cases ranging from 6 months to 78 months (median 33 months). Of these, 13 were stage I, 3 were stage II and 7 were stage III ITs. Out of 23 patients, 17 patients were alive without evidence of disease recurrence during the last follow up. Adverse events in the form of death and local recurrence occurred in 6 patients. One patient died of the disease at 7 months duration from the disease onset (stage III, grade II IT). Conclusion: Morphological spectrum of IT of ovary is varied. Immature mesenchyme was seen in all the cases of IT of ovary and its presence should prompt a careful search for immature neuroepithelium. Stage I IT of ovary has better prognosis. Combination of surgery and chemotherapy can give longer survival even in recurrent disease.
