Literature searches were conducted across PubMed, Cochrane Library and ScienceDirect between January 2018 and July 2025. Eligible studies included randomized controlled trials, cohort studies and observational analyses involving adult patients with NETs. The primary outcomes were progression-free survival (PFS) and overall survival (OS). A total of 271 studies were screened and 22 met the inclusion criteria. Median PFS across therapies ranged between 2 and 23 months, whereas OS ranged between 9.6 and 60 months, depending on treatment type. Dual checkpoint inhibitors (nivolumab plus ipilimumab) demonstrated durable benefits, with OS time exceeding 55 months in some cohorts, whereas peptide receptor radionuclide therapy (PRRT) achieved a median PFS time of 22.8 months compared with 8.5 months for high-dose octreotide. Furthermore, targeted agents, such as sunitinib and nintedanib, improved PFS to ~11 months, with OS time extending beyond 30 months. Chemotherapy regimens such as CAPTEM yielded a PFS of 7-11 months. In conclusion, the present study revealed that NET therapies show heterogeneous but clinically meaningful benefits. PRRT, targeted therapy and combination regimens were revealed to be associated with the most durable outcomes, whereas immunotherapy demonstrated promise in selected patients.

However, their roles in cancer progression and treatment response remain poorly understood. The present study investigated the baseline expression of ULK1 and USP20 across several cancer cell lines and evaluates the effects of their silencing on chemosensitivity. The findings of the present study showed that ULK1 was highly expressed in MCF-7 breast cancer cells and minimally in U87 glioblastoma cells. USP20 showed high expression in MCF-7, MDA-MB-231 and HepG2, and low expression in others. Combined silencing of ULK1 and USP20 with chemotherapy altered drug sensitivity across cancer types. ULK1 knockdown increased drug sensitivity and induced cell death in HepG2, MDA-MB-231 and PanC1 cell lines, but conferred chemoresistance in MCF-7, A549 and U87 cancer cells. Similarly, USP20 silencing sensitized MCF-7, HepG2 and PanC1 cells to chemotherapy, while enhancing survival in U87 cells. These results suggest that ULK1 and USP20 have cancer-type-specific roles in modulating autophagy and chemotherapy response.
