Behavior of transitional cell carcinoma of the bladder during the third decade of life remains a controversial subject. During the period 1980-1988, we treated 7 patients (4 male and 3 female), 25 years of age or less (mean age 19.3, range 14-25), with transitional cell carcinoma of the bladder. Until now, all patients are alive and without disease during 12-50 months after surgery. In 6 of the 7 patients, endoscopic resection was the choice treatment for superficial stage A/O. The seventh patient underwent a partial cystectomy for a B1 Jewet stage cell carcinoma. We conclude that transitional cell carcinoma of the bladder in patients under 25 years of age has a less aggressive biological behavior. Therefore, ultrasonographic examinations and serial urine cytology represent the elective test for follow-up. Cystoscopy would only be performed in doubtful cases.

SMARCB1/INI-1-Deficient sinonasal carcinoma demonstrates a poor prognosis but favorable clinical outcomes after PD-1/PD-L1 inhibitor therapy: A case series.

Despite advances in multimodal cancer therapy, such as combining radical surgery with high-intensity chemoradiotherapy, for SMARCB1/INI-1-deficient sinonasal carcinoma (SDSC), the prognosis of patients remains poor. Immunotherapy is gaining increasing popularity as a novel treatment strategy for patients with SMARCB1/INI-1-deficient tumors. Herein, we report on the management of three patients with SDSC who received PD-1/PD-L1 inhibitor therapy as a part of multimodal therapy based on surgery and chemoradiotherapy.

Despite being designated as "noncarcinogenic" human papillomavirus (HPV) types, mono-infection with HPV6 or HPV11 has been found in squamous cell carcinomas (SCCs) at specific sites, including the larynx, penis, anus, and rarely, the lower female genital tract. The association between clinicopathologic features, viral status, and the carcinogenic mechanisms related to these low-risk HPVs remains unclear. The current study characterizes a series of low-risk HPV6 and HPV11-associated SCCs of the uterine cervix (6 cases) and vulva (2 cases).

Intraductal papillary neoplasm of the bile duct (IPNB) is a precursor lesion to biliary tract carcinoma. It is characterised by papillary growth within the bile ducts. The diagnosis and management of IPNB are challenging due to its varying presentations and overlapping features with other biliary diseases.

Oral squamous cell carcinoma (OSCC) accounts for approximately 90% of all oral cancers, significantly impacting the survival and quality of life of patients. Exosomes, small extracellular vesicles released by cells, play a crucial role in intercellular communication in cancer. Nevertheless, their function and mechanism in OSCC remain elusive.

Purpose: This study aims to assess the impact of unclassified renal cell carcinoma (uRCC) on clinical, pathological, and oncological outcomes compared with clear cell renal cell carcinoma (ccRCC).
Materials And Methods: We analyzed the data of 48 uRCC and 688 ccRCC cases, collected from a histopathological database at a single center from July 2011 to August 2019. uRCC cases were confirmed according to the 2016 World Health Organization classification.
