Objectives Cervical lymphoma is a rare condition and may be difficult to diagnose and treatment. Large B-cell lymphoma is among the most common sub-type of Cervical Lymphoma.No standard treatments for patients with this entity have been introduced currently. Only case reports published in the literature and indicated the R-CHOP regimens in combination with involved field radiation therapy (RT) are effective. We retrospectively analyse the 37 patients with primary cervix large B-cell lymphoma and outcome after R-CHOP in combination with RT.

Methods Thirty-seven untreated primary cervix large B-cell lymphoma patients received R-CHOP like regimens. Fourteen of them underwent subsequent RT. Thirteen of them received subsequent salvage chemotherapy.

Results Of 37 patients underwent R-CHOP chemotherapy, only 3 patients received the radical surgery. An overall response rate (ORR) was 78.3% after completion of chemotherapy.The PFS and OS rate at 5 years were 58% and 69%, respectively. For 14 patients who received RT after R-CHOP, an estimated ORR were 89.2%. For all patients, The PFS reached the platform after 2 years follow up and the OS after 3 years according to the survival curve analysis. The international prognostic index (IPI) score were the only predictor of worse outcome.

Conclusions R-CHOP regimens plus involved field radiation therapy led high response rate in primary cervix large B-cell lymphoma. Patients with high IPI had a trend of less satisfied with R-CHOP regimens plus IFRT. Future prospective and multicenter studies are needed. By the way, we are conducting a gene expression profile between DLBCL-unspecified and primary cervix large B-cell lymphoma by NGS.
