Summary: There is a risk of progression in the remnant pancreas after resection of noninvasive IPMNs, including both invasive and noninvasive progression. Multifocality and high-grade dysplasia are associated with invasive progression. Patients with high-risk features should be monitored more closely.

Summary: The distinction between PUNLMP and low-grade noninvasive papillary urothelial carcinoma is controversial and unnecessary for treatment and prognosis. Combining these two tumor types into a single category (NIPUN) can improve diagnostic accuracy among medical imaging observers.

Summary: Metastatic recurrence occurs in over 25% of upper tract urothelial carcinoma patients treated with radical nephroureterectomy, with lymphovascular invasion being a predictor of metastatic recurrence. Hepatic and osseous recurrences have relatively quicker onset and less favorable prognosis.

Summary: This study aimed to measure morphometric features relevant to grading criteria in noninvasive papillary urothelial carcinoma (NPUC) and build simplified classification models to distinguish between different grades objectively. The findings indicate that nuclear morphometry and automated mitotic figure counts can be used to objectively differentiate the grades of NPUC. These quantitative elements have the potential to revolutionize pathologic assessment and improve the prognostic utility of grade.

Summary: This study retrospectively evaluated the clinicopathologic features and recurrence rates of inverted noninvasive urothelial papillary tumors. The results showed that inverted papillary urothelial tumors have lower recurrence rates and better prognosis. The study identified tumor number as an important prognostic factor for the disease-free survival of low malignant potential and high-grade papillary urothelial carcinoma with an inverted growth pattern.

Summary: This study retrospectively analyzed 1283 patients with papillary thyroid carcinoma (PTC) and found a high incidence of bilateral multifocality. Bilateral multifocality was closely associated with clinical pathological characteristics such as age, gender, tumor size, and lymph node metastasis. It was also identified as an independent predictor of PTC recurrence. Therefore, patients with bilateral multifocal PTC may benefit from more frequent follow-up to detect recurrences earlier.

Summary: This study evaluated the predictors of malignancy in intraductal papillary neoplasm of the bile duct (IPNB) according to anatomical location and investigated the prognosis without surgery. The results showed that extrahepatic IPNB (E-IPNB) had a higher rate of malignancy than intrahepatic IPNB (I-IPNB), with mural nodule > 12 mm in I-IPNB and mural nodule enhancement in E-IPNB being predictive factors for malignancy.

Summary: ITGA3 is overexpressed in papillary thyroid carcinoma (PTC), especially in those with higher tumor invasion grades and lymph node metastasis, and was associated with recurrence and poor relapse-free survival (RFS) of PTC. High expression of ITGA3 may have the potential role of predicting PTC recurrence and lymph node metastasis.

Summary: The study demonstrated that eIF6 expression was significantly increased in HCC and correlated with its pathological progression. eIF6 served as a new diagnostic biomarker and an independent risk factor for OS in HCC patients. Functional studies showed that deletion of eIF6 exhibited tumor-suppressor activity in HCC cells.

Summary: In this study, a transcriptional network of cell cycle dysregulation in noninvasive papillary urothelial carcinoma (NIPUC) was identified. The activity of transcription factors in this network was associated with mutational burden, copy number instability, and other characteristics. The findings suggest that transcription factor activity plays a prominent role in driving cell cycle dysregulation in NIPUC.

Summary: The study found that patients with papillary gastric adenocarcinoma (PGC) were generally older and had tumors located in the upper 1/3 of the stomach, with characteristics such as serosal infiltration and early lymph node metastasis. The risk factor for poor survival in PGC patients was papillary adenocarcinoma.

Summary: This retrospective study analyzed pediatric patients with papillary thyroid carcinoma (PTC) and found that younger patients had a higher risk of aggressive features and recurrence compared to older patients. The study suggests that prophylactic or therapeutic lymph node dissection should be considered for younger patients with positive preoperative thyroid-stimulating hormone (TSH), tumors larger than 2 cm, lateral lymph node metastases, and more than 5 lymph node metastases to reduce the risk of recurrence.

Summary: It is controversial whether Gleason grade should be assigned to intraductal carcinoma of the prostate (IDC-P) and if the prognostic value of comedonecrosis associated with IDC-P is equivalent to that in conventional/invasive prostatic adenocarcinoma (CPA) as a Gleason grade 5 pattern. This study evaluated radical prostatectomy findings and postoperative outcomes in 287 patients with CPA exhibiting any Gleason pattern 5. The presence of necrosis only in IDC-P was found to be associated with significantly worse oncologic outcomes, compared with necrosis only in CPA, suggesting that IDC-P necrosis should not be simply considered as a grade 5 pattern.

Summary: This study evaluated the clinical significance of intraoperative frozen section analysis (FSA) in patients with upper urinary tract cancer. The results showed that FSA can significantly reduce the risk of positive surgical margins in patients with ureteral tumors, but routine FSA for upper urinary tract cancer did not improve long-term oncologic outcomes significantly.

Summary: Quantification of perineural invasion on prostate biopsy showed significance as an independent predictor of prognosis, with multifocal perineural invasion and >1 perineural invasion per 10-mm tumor associated with worse outcomes after radical prostatectomy. Additionally, assigning points for multifocal perineural invasion improved the accuracy of predicting 5-year recurrence-free survival.

Summary: Androgen deprivation therapy is the main treatment for advanced prostate cancer, and relugolix has been developed as an oral alternative. Previous studies have shown comparable efficacy between relugolix and other gonadotropin-releasing hormone antagonists or agonists. This review summarizes the design, development, and therapeutic application of relugolix and discusses its potential as a promising oral alternative to injectable therapy.

Summary: The fifth edition of WHO Classification of Tumors series for urinary and male genital tract tumors has been published after six years of the fourth edition. New treatment approaches and molecular data on urological cancers have been implemented during these years. Although morphology remains the basis for taxonomy, a molecular approach and new therapeutic modalities like immunotherapy are emerging. More data is required for the application of these advances in routine pathology practice and patient management.

Summary: Nested urothelial carcinoma (NUC) and large nested urothelial carcinoma (LNUC) of the upper urinary tract are rare tumors. This study provides insights into their clinicopathological and molecular characteristics, revealing better clinical outcomes for LNUC and a higher prevalence of pathogenic mutations in FGFR3 and PIK3CA in LNUC.
