AI Article Synopsis
- Non-transitional cell carcinomas (non-TCC) in the upper urinary tract, such as squamous cell carcinoma, adenocarcinoma, and small cell carcinoma, are uncommon, with limited case reports available.
- A review of 305 patients treated for upper tract urothelial carcinoma between 1983 and 2013 identified only 5 cases of non-TCC (1.6%).
- The findings indicated that non-TCC cases had a significantly lower cancer-specific survival rate compared to transitional cell carcinoma (TCC) patients, with no occurrences of intravesical recurrence.
Article Abstract
Non-transitional cell carcinomas (non-TCC) of the upper urinary tract as squamous cell carcinoma (SCC), adenocarcinoma, and small cell carcinoma (SmCC) are rare with few case reports in the literature. We retrospectively reviewed our patients who surgically treated for upper tract urothelial carcinoma from 1983 to 2013 for non-TCC pathological cancer characteristics and survival. Among 305 patients, only 5 (1.6%) cases were found: One case of SmCC, another had adenocarcinoma, and 3 SCC cases. None of them had intravesical recurrence and the cancer-specific survival for non-TCC cohort is markedly decreased (log-rank = 0.01) compared to TCC patients.

Purpose: Immune checkpoint inhibitors (ICIs) have demonstrated promise in the treatment of various cancers. Single-drug ICI therapy (immuno-oncology [IO] monotherapy) that targets PD-L1 is the standard of care in patients with advanced non-small cell lung cancer (NSCLC) with PD-L1 expression ≥50%. We sought to find out if a machine learning (ML) algorithm can perform better as a predictive biomarker than PD-L1 alone.

The challenge of "false positive" signals significantly complicates tumor localization and surgical resection, which are pivotal for successful tumor surgeries. Therefore, the development of a method for preoperative tumor localization and intraoperative margin determination holds considerable promise for improving surgical outcomes. In this study, a zero-crosstalk ratiometric tumor-targeting near-infrared (NIR) fluorescent probe was developed for precise cancer diagnosis and intraoperative navigation via NIR fluorescence imaging.

Objectives: It is significant to know how much early detection and screening could reduce the proportion of occult metastases and benefit NSCLC patients.
Methods: We used previously designed and validated mathematical models to obtain the characteristics of LC in the population including undetectable metastases at the time of diagnosis. The survival was simulated using the survival functions from Surveillance, Epidemiology and End Results (SEER) data stratified by stage.

BACKGROUND Studies using transgenic mouse models have demonstrated that estrogen is necessary for the development of cervical cancer, particularly in tissues responsive to estrogen. Estrogen also protects cervical cancer cells from apoptosis, suggesting its role in the survival and persistence of cancer cells. CASE REPORT An 84-year-old woman with diabetes mellitus, hypertension, and stage III chronic renal failure was diagnosed with cervical squamous cell carcinoma, FIGO stage IB2.
