Purpose: Modified FOLFIRINOX (mFFX), a standard chemotherapy regimen for advanced pancreatic cancer (APC), is expected to be associated with a higher risk of chemotherapy-induced nausea and vomiting (CINV). Herein, we conducted a retrospective cohort study to evaluate the efficacy and safety of a three-drug combination of 5-hydroxytryptamine-3 receptor antagonists (5HT3RA), dexamethasone (DEX), and neurokinin 1 receptor antagonists (NK1RA) for the prevention of CINV during mFFX therapy.
Methods: This study enrolled patients with APC who received mFFX as initial therapy with a combination of 5HT3RA, DEX, and NK1RA as antiemetic prophylaxis. The primary endpoint was the complete response (CR) rate during cycle 1, which was defined as no emetic episodes and no rescue medication use during the overall period (0-120 h). Safety was also evaluated with a focus on hyperglycemia, which is a concern in patients with APC.
Results: Seventy patients were eligible for this retrospective analysis. The CR rate during the overall period was 51.4%. Significant nausea, defined as grade 2 or higher, peaked to 77.1% on days 4-5, but remained above 65% until day 7. Hyperglycemia occurred in 37.1% of patients, and 34.3% were grade 3 hyperglycemia.
Conclusions: CINV induced by mFFX was poorly controlled even with prophylactic antiemetic therapy using 5HT3RA, DEX, and NK1RA, and was found to persist beyond 5 days. Enhanced antiemetic measures for mFFX are desirable. However, in patients with diabetes mellitus complications, sparing of steroids and glycemic control should be considered.

Introduction: Cisplatin-based highly emetogenic chemotherapy is recommended in combination with neurokinin-1 receptor antagonist (NK1RA), 5-hydroxytriptamine-3-receptor antagonist (5HT3RA), dexamethasone (DEX), and olanzapine. However, olanzapine is contraindicated in patients with pre-existing diabetes mellitus (DM). This study compared the efficacy of a triplet antiemetic regimen (NK1RA, 5HT3RA, and DEX) in patients with and without pre-existing DM treated with cisplatin-based chemotherapy.

Article Synopsis
- Palonosetron is a second-generation anti-nausea drug that might be more effective than first-generation medications, and this study explores how dexamethasone (DEX) works with it during chemotherapy.
- Researchers compared the effects of giving DEX for 1 day versus 3 days in preventing nausea and vomiting after moderately emetogenic chemotherapy (MEC), using data from studies published between 1990 and 2020.
- The findings showed that while the 3-day DEX group had a higher rate of no vomiting, there were no major differences in most anti-nausea effects, suggesting that DEX treatment could be shortened to just 1 day when paired with palonosetron.

Trastuzumab deruxtecan is classified as an anticancer agent that poses a moderate emetic risk in the international guidelines for antiemetic therapy. The guidelines recommend emesis prophylaxis using a two-drug combination therapy comprising a 5-hydroxytryptamine-3 receptor antagonist (5-HT3RA) and dexamethasone (DEX). However, the high incidence of nausea and vomiting associated with trastuzumab deruxtecan is problematic.

Introduction: Dexamethasone (DEX)-sparing strategy with 5-hydroxytryptamine-3 receptor antagonist (5HT3RA) and aprepitant (APR), as triplet antiemetic prophylaxis, is associated with poor control of delayed chemotherapy-induced nausea and vomiting (CINV) in patients receiving carboplatin (CBDCA)-based chemotherapy. This study aimed to evaluate whether using palonosetron (PALO) as a 5HT3RA provides superior control with CINV than first-generation (1st) 5HT3RA in triplet antiemetic prophylaxis with a DEX-sparing strategy.
Methods: Pooled patient-level data from a nationwide, multicenter, and prospective observational study were analyzed to compare the incidence of CINV between patients administered PALO and 1st 5HT3RA in combination with 1-day DEX and APR.
