Chemoradiotherapy with high-dose cisplatin every three weeks is the standard adjuvant treatment for patients with locally advanced squamous cell carcinoma of the head and neck with high risk for recurrence. However, the cisplatin dose is frequently reduced because of dose-related toxicities which can result in insufficient cisplatin delivery. Chemoradiotherapy with weekly cisplatin at a dose of 40 mg/m2 is widely used as a possible alternative, albeit without sufficient evidence. This clinical trial was conducted to prove the noninferiority of weekly cisplatin to three weekly cisplatin plus radiation therapy (RT).

This update on the PACIFIC trial comparing durvalumab with placebo in patients with unresectable, stage III non–small-cell lung cancer demonstrated robust and sustained OS and durable PFS benefit. The updated, exploratory analyses of survival, approximately 5 years after the last patient was randomly assigned demonstrate robust and sustained OS and durable PFS benefit with durvalumab after chemoradiotherapy. An estimated 42.9% of patients randomly assigned to durvalumab remain alive at 5 years and 33.1% of patients randomly assigned to durvalumab remain alive and free of disease progression. These results establish a new benchmark for standard of care in this setting.

Initial results of the PREOPANC trial — comparing the addition of neoadjuvant chemoradiation therapy of gemcitabine combined plus Gy radiotherapy to standard care — failed to demonstrate a statistically significant overall survival (OS) improvement versus standard care of upfront surgery followed by adjuvant therapy. The long-term results, however, demonstrate significant benefit with neoadjuvant chemoradiation therapy consisted of gemcitabine combined plus Gy radiotherapy. The five year OS rate was 20.5% (95% CI, 14.2 to 29.8) with neoadjuvant chemoradiotherapy and 6.5% with upfront surgery.

This study reports long term outcomes on CALGB 40603 at a median follow-up of 7.9 years. Event-free survival and other LTOs were not significantly improved with either study drug overall or in studied sub-populations. Results showed that patients with any residual disease had significantly worse outcomes. This finding supports considering adjuvant therapy even in the setting of minimal residual disease.

This update of the GO29365 study shows significant survival benefit with pola + BR vs BR alone in R/R, transplant ineligible DLBCL. In the randomization arms, median progression-free survival was 9.2 vs 3.7 months and median overall survival was 12.4 vs 4.7 months for the pola + BR arm vs the BR arm. In the extension cohort, the OR rate was 41.5%, and the CR rate was 38.7%; PFS and OS were 6.6 months and 12.5 months, respectively.

This open-label, randomized phase II-III study of 191 patients with locally advanced or metastatic BTC compared triplet therapy of oxaliplatin, irinotecan, and infusional fluorouracil (mFOLFIRINOX), with doublet therapy consisting of cisplatin and gemcitabine (CISGEM). Triplet therapy did not outperform doublet therapy in this study.
