Impact of obinutuzumab alone and in combination for follicular lymphoma

Immune-inflammatory modulation by natural products derived from edible and medicinal herbs used in Chinese classical prescriptions

BACKGROUND

Edible and medicinal herbs1 (EMHs) refer to a class of substances with dual attribution of food and medicine. These substances are traditionally used as food and also listed in many international pharmacopoeias, including the European Pharmacopoeia, the United States Pharmacopoeia, and the Chinese Pharmacopoeia. Some classical formulas that are widely used in traditional Chinese medicine include a series of EMHs, which have been shown to be effective with obvious characteristics and advantages. Notably, these EMHs and Chinese classical prescriptions2 (CCPs) have also attracted attention in international herbal medicine research because of their low toxicity and high efficiency as well as the rich body of experience for their long-term clinical use.

PURPOSE

Our purpose is to explore the potential therapeutic effect of EMHs with immune-inflammatory modulation for the study of modern cancer drugs.

STUDY DESIGN

In the present study, we present a detailed account of some EMHs used in CCPs that have shown considerable research potential in studies exploring modern drugs with immune-inflammatory modulation.

METHODS

Approximately 500 publications in the past 30 years were collected from PubMed, Web of Science and ScienceDirect using the keywords, such as natural products, edible and medicinal herbs, Chinese medicine, classical prescription, immune-inflammatory, tumor microenvironment and some related synonyms. The active ingredients instead of herbal extracts or botanical mixtures were focused on and the research conducted over the past decade were discussed emphatically and analyzed comprehensively.

RESULTS

More than ten natural products derived from EMHs used in CCPs are discussed and their immune-inflammatory modulation activities, including enhancing antitumor immunity, regulating inflammatory signaling pathways, lowering the proportion of immunosuppressive cells, inhibiting the secretion of proinflammatory cytokines, immunosuppressive factors, and inflammatory mediators, are summarized.

CONCLUSION

Our findings demonstrate the immune-inflammatory modulating role of those EMHs used in CCPs and provide new ideas for cancer treatment in clinical settings.

Comparative analysis of rituximab or obinutuzumab combined with CHOP in first-line treatment of follicular lymphoma

Purpose

Rituximab (R) or obinutuzumab (G) combined with CHOP chemotherapy are used in previously untreated follicular lymphoma (FL). The aim is to compare in real life setting the efficacy and safety of these therapeutic strategies and assess the economic impact of introducing G.

Methods

This retrospective study, performed in 3 centers, included data from all patients who received R-CHOP or G-CHOP for previous untreated FL from June 1st, 2016 to December 31st, 2020. Progression-Free Survival (PFS) were estimated according to the Kaplan–Meier method. A budgetary impact model was performed from the French health care system’s perspective.

Results

N = 124 patients were included (58 G-CHOP; 66 R-CHOP). Fifty-one and 57 patients achieved a complete response at the end of induction in the G-CHOP and R-CHOP group, respectively. PFS was not significantly longer in the G-CHOP group (HR 0.28; 95% CI 0.08–0.97; p value = 0.14). Hematological toxicity occurred more frequently with G-CHOP than R-CHOP during induction treatment (n = 58; 100% vs. n = 61; 92%), including higher severe neutropenia (grade ≥ 3) (n = 26; 45% vs. n = 23; 35%). Infusion-related reactions during the first infusion occurred more frequently with G-CHOP (n = 19; 33% vs. n = 16; 24%). The introduction of a completed G treatment (induction and maintenance) results in an additional cumulative cost per patient estimated at more than €30,000.

Conclusion

Similar results were found in the GALLIUM subgroup analysis study, suggesting that at this time there is no absolute benefit to administer G-CHOP instead of R-CHOP in all patients with previously untreated FL and may encourage clinical and economic trials including quality of life data.
