Multicenter Study Comparative Study
Comparative effectiveness of palliative chemotherapy versus neoadjuvant chemotherapy followed by radical cystectomy versus cystectomy followed by adjuvant chemotherapy versus cystectomy for regional node-positive bladder cancer: A retrospective analysis: KCSG GU 17-03.
The regional lymph node-positive bladder cancer was classified as stage IV in the AJCC 7th edition but was changed to stage IIIB in the 8th edition, revised in 2018. Among the various studies involving immune checkpoint inhibitors, groups that had only lymph node metastasis showed better outcomes than those with distant metastasis. Therefore, it is necessary to rethink the treatment strategy for lymph node-positive bladder cancer. ⋯ For each group, median overall survival was 19.3, 49.1, 42.6, and 11.2 months, respectively. This study represents an advancement in understanding the impact of clinical treatment patterns of lymph node-positive bladder cancer through comparison of survival data of patients treated with different therapeutic strategies. Combined treatment resulted in better outcomes than did single treatments.

To compare the relative efficacy of immune checkpoint inhibitors (ICIs) or chemotherapy (CT) alone, or their combination modality in the first-line treatment of advanced nonsmall cell lung cancer (NSCLC). ⋯ The findings support the rationale for using pembrolizumab alone in the first-line treatment of PD-L1 ≥ 50% advanced NSCLC due to the similar OS and lower grade ≥ 3 TRAEs. However, the combination of ICIs and chemotherapy is strongly recommended in patients with PD-L1 ≤ 49% for significant survival benefit.

This study aimed to investigate the characteristics of colonic neuroendocrine neoplasms (NENs) and to validate the prognostic value of the European Neuroendocrine Tumor Society (ENETS) and American Joint Committee on Cancer (AJCC) 8th staging systems. ⋯ Our study revealed that tumors originating from the midgut and the hindgut shared different clinicopathological features. The AJCC 8th staging system and the ENETS system appeared to have similar prognostic ability for colonic NEC/MANEC.
