Introduction/Background 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 primary cervix large B-cell lymphoma 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. Shanghai Cancer Center is one of the top pathological consultant center in China. We retrospectively analyse the 37 patients with primary cervix large B-cell lymphoma and outcome after R-CHOP in combination with RT.

Methodology 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.

Conclusion 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 in order to get the valuable information to improve the treatment outcome even by using some targeted drugs. The data will be show in the next few months.
