OBJECTIVE: To evaluate the efficacy and safety of ruxolitinib in patients with polycythemia vera (PV). METHODS: The clinical data of patients with PV treated with ruxolitinib in Peking Union Medical College Hospital from January 1, 2013 to December 31, 2019 were retrospectively analyzed. The starting dose of oral ruxolitinib was 10 mg twice daily and could be increased after 3 months of treatment if hematocrit (HCT) control was not achieved. HCT control was defined as HCT<45% in the absence of phlebotomy. RESULTS: Thirty-three patients (17 males and 16 females) were treated with ruxolitinib at a median age of 50 (21-72) years. JAK2V617F and JAK2exon12 alleles were detected in 31 and 2 patients, respectively. Before treatment, median hemoglobin level was 187 (166-208) g/L, median white blood cell and platelet level was 10.4 (5.0-15.8)×10⁹/L and 457(237-677)×10⁹/L, respectively. Totally 17 patients (51.5%) who were resistant to or intolerant of hydroxyurea were treated with ruxolitinib as second-line therapy, and 16 patients (48.5%) were treated with ruxolitinib as first-line therapy voluntarily. The median time since PV diagnosis to treatment of ruxolitinib was 47 (3-188) months. By December 31, 2019, all the patients continued to receive ruxolitinib. The median duration of ruxolitinib exposure was 19 (2-91) months. Both in the first-line therapy group and second-line therapy group, 15 cases (accounting for 93.8% and 88.2%, respecitvely) achieved HCT control. The median time from start of therapy to HCT control was 2.2 (0.8-11.6) months. One patient (3.0%) had disease progression after HCT control. The most common hematologic adverse events included anemia and thrombocytopenia, according to CTCAE classification, including 1 case of grade 1 anemia (3.0%) and 1 case of grade 2 thrombocytopenia (3.0%). There was no thromboembolic event occurred during the therapy of ruxolitinib. CONCLUSION The remission rate of HCT in PV patients treated with ruxolitinib is high, and adverse reactions are rare. Ruxolitinib is effective in HCT control and generally well tolerated in patients with PV.

OBJECTIVE: To retrospectively analyze the efficacy and safety of ruxolitinib therapy for children with thalassemia after unrelated or haploidentical stem cell transplantation. METHODS: From March 2020 to March 2021, 22 patients received successfully allogeneic hematopoietic stem cell transplantation in the Zhongshan Hospital of Xiamen University, from +30 to 100 days,those patients received ruxolitinib therapy (2.5 mg, twice daily) and all adverse reactions were observed, include aGVHD, cGVHD, CMV and EBV infection. RESULTS: 22 patients underwent allogeneic stem cell transplantation, 5 patients were diagnosed as aGVHD, 3 patients had grade I－II skin GVHD and 2 patients had grade II intestinal GVHD, those patients were cured. All patients were followed up for more than 21 weeks, 4 cases developed cGVHD, including 3 cases of localized liver GVHD and 1 case of pulmonary GVHD, those were relieved after active treatment. 8 patients had elevated EBV copies (>3×10³/ml), and 3 patients had increased CMV copies, the patients recovered after immunosuppressant and antiviral treatment. There was no CMV infection and EBV related post-transplantant lymphoproliferative disorders(PTLD), and no transplant related deaths. CONCLUSION Ruxolitinib can effectively reduce the incidence and severity of GVHD without affecting the hematopoietic recovery, and improve the survival status of thalassemia children after transplantation.

Zanubrutinib is a highly selective second-generation BTK inhibitor developed in China and first approved by the U.S. Food and Drug Administration (FDA) as a novel antineoplastic drug. In recent years, with the birth of molecularly targeted drugs, the treatment of B-cell lymphoma have entered the era of targeted therapy, and immunotherapy has been widely accepted. Especially in some relapsed and refractory lymphomas, zanubrutinib has shown deep and sustained remissions and a favorable safety, which lays a foundation for precision therapy. In this review the clinical application and new progress for zanubrutinib in B-cell lymphoma was summarized briefly.

Objective: To investigate the clinicopathological features of gastrointestinal stromal tumor (GIST) with KIT/PDGFRA "homozygous mutation", the efficacy of targeted therapy and the prognosis. Methods: A retrospective cohort study and propensity score matching were used. "Homozygous mutation" was defined as the detection of KIT/PDGFRA gene status of GIST by Sanger sequencing, which showed that there was only mutant gene sequence in the sequencing map, lack of wild-type sequence or the peak height of mutant gene sequence was much higher than that of wild-type gene sequence (> 3 times). "Heterozygous mutation" was defined as the mutant gene sequences coexisted with wild type gene sequences, and the peak height was similar (3 times or less). The clinicopathological data and follow-up information of 92 GIST patients with KIT/PDGFRA "homozygous mutation" were collected from 4 hospitals in Shanghai from January 2008 to May 2021 (Renji Hospital, Shanghai Jiaotong University School of Medicine: 70 cases; Zhongshan Hospital, Fudan University: 14 cases; Changhai Hospital, Naval Military Medical University: 6 cases and Ruijin Hospital, Shanghai Jiaotong University School of Medicine: 2 cases). Patients with perioperative death, other malignancies, and incomplete clinicopathological information were excluded. The clinicopathological features of the patients and the efficacy of targeted drug therapy were observed and analyzed. The efficacy was evaluated using Choi criteria, which were divided into complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD). In addition, a total of 230 patients with high-risk GIST with "heterozygous mutation" in exon 11 of KIT gene and 117 patients with recurrent or metastatic GIST with "heterozygous mutation" in exon 11 of KIT gene were included. The propensity score matching method was used to match GIST patients with "heterozygous" and "homozygous" mutations in exon 11 of KIT gene (1∶1) for survival analysis. The disease-free survival (DFS) between two groups of high-risk GIST patients who underwent complete surgical resection were compared. And progression-free survival (PFS) in patients with recurrent or metastatic GIST were compared. Results: Of the 92 GIST cases with KIT/PDGFRA "homozygous mutation", 58 were males and 34 were females, with a median onset age of 62 (31-91) years. Primary GIST 83 cases. Primary high-risk GIST (53 cases), metastatic GIST (21 cases) and recurrent GIST (9 cases) accounted for 90.2% (83/92). There were 90 cases of KIT gene"homozygous mutation" (exon 11 for 88 cases, exon 13 for 1 case, exon 17 for 1 case), and 2 cases of PDGFRA gene "homozygous mutation" (exon 12 for 1 case, exon 18 for 1 case). The median follow-up time was 49 (8-181) months. Among the 61 cases of primary localized GIST undergoing complete surgical resection, 2 cases were intermediate-risk GIST, 5 cases were low-risk GIST, and 1 case was very low-risk GIST, of whom 1 case of intermediate-risk GIST received 1-year adjuvant imatinib mesylate (IM) therapy after operation, and no tumor recurrence developed during the follow-up period. The remaining 53 cases were high-risk GIST, and follow-up data were obtained from 50 cases, of whom 22 developed tumor recurrence during follow-up. Of 9 patients directly receiving neoadjuvant targeted therapy (IM or avapritinib), 5 had complete imaging follow-up data, and the evaluation of efficacy achieved PR. Of all the 92 GIST cases with KIT/PDGFRA "homozygous mutation", 50 (54.4%) had tumor metastasis or tumor recurrence or progression during follow-up, and 12 (13.0%) died of the tumor. Survival analysis combined with propensity score showed that in 100 cases of high-risk GISTs with complete resection, GISTs with "homozygous mutation" in exon 11 of KIT gene had shorter disease-free survival (DFS) than GISTs with "heterozygous mutation" in exon 11 of KIT gene (median DFS: 72 months vs. 148 months, P=0.015). In 60 cases of recurrent or metastatic GISTs with KIT gene exon 11 mutation, IM was used as the first-line treatment, and the progression-free survival (PFS) of GISTs with "homozygous mutation" was shorter compared to GISTs with "heterozygous mutation" (median PFS: 38 months vs. 69 months, P=0.044). The differences were statistically significant. Conclusions: "Homozygous mutation" in KIT/PDGFRA gene is associated with the progression of GIST. The corresponding targeted therapeutic drugs are still effective for GIST with KIT/PDGFRA gene "homozygous mutation". Compared with GIST patients with "heterozygous mutation" in KIT exon 11, GIST patients with "homozygous mutation" in KIT exon 11 are more likely to relapse after surgery and to develop resistance to IM. Therefore, it is still necessary to seek more effective treatment methods for this subset of cases.

Objective: To evaluate the efficacy and tolerability of ruxolitinib combined with prednisone, thalidomide and danazol for treatment of in myelofibrosis (MF). Methods: Patients of MF according to the WHO 2016 criteria, received ruxolitinib (RUX) combined with prednisone, thalidomide and danazol (PTD). The response, changes of blood counts and adverse events were evaluated. Results: Six PMF and one post-ET MF patients were enrolled. Four patients presented JAK2V617F mutation, one CALR mutation, one MPL mutation, one triple-negative. Responses per IWG-MRT criteria were clinical improvement in 5 patients, stable disease in 2 ones, spleen response in 6 ones. All of 7 patients were symptomatic responses, four patients achieved at least 50% improvement from baseline on MPN-SAF TSS. Three patients initially treated with RUX alone, all of 3 patients experienced treatment-associated anemia and thrombocytopenia. Then these 3 patients received RUX combined with PTD, both hemoglobin and platelet increased significantly. Four patients initially treated with RUX combined with PTD. Increased levels of hemoglobin and platelet were seen in all of 7 patients received RUX combined with PTD with maximum increased hemoglobin of 30(18-54) g/L and maximum increased platelets of 116(13-369)×10(9)/L, respectively from baseline. The treatment dose of RUX increased due to improved platelet count in 3 patients. The frequent non-hematologic adverse events grade 1-2 were constipation, abdominal distension, crura edema and increased ALT. Conclusions: RUX combined with PTD for treatment of MF may modulate initial hematologic toxicity observed when RUX alone, and may increase response due to improved levels of hemoglobin or platelet.

Objective: To improve the knowledge and experience of ibrutinib combined with CAR-T cells in the treatment of high-risk chronic lymphoblastic leukemia (CLL) patients or small lymphocytic lymphoma (SLL) with TP53 gene aberration. Methods: One case of del (17p) CLL patients with BCL-2 inhibitor resistance was treated with ibrutinib combined with CAR-T cells, successfully bridged to allogeneic hematopoietic stem cell transplantation (allo-HSCT) , and the relative literatures were reviewed. Results: The patient was a young female with superficial lymph node enlarging at the beginning of the onset. Lymph node biopsy was confirmed as small lymphocytic lymphoma (SLL) without del (17p) . The disease progressed rapidly to CLL/SLL with del (17p) and bone marrow hematopoietic failure 2 years later. Firstly, the patient was treated with BCL-2 inhibitor (Venetoclax) , and the enlarged lymph nodes shrank significantly 2 months later. After 3 months, the disease progressed rapidly. The spleen was enlarged to 16 cm below the ribs, the neck lymph nodes was rapidly enlarged, and the superior vena cava syndrome appeared, which were mainly attributed to venetoclax resistance; so BTK inhibitor (ibrutinib) was used continuously after venetoclax discontinuation. Partial remission (PR) was achieved without lymphocytosis after 2 months, then ibrutinib was combined with CAR-T cells targeting CD19 antigen. Grade 1 of cytokine release syndrome (CRS) appeared after CAR-T cells infusion, and the complete remission (CR) was achieved after 1 month both in bone marrow and peripheral blood, with minimal residual disease (MRD) negative, then bridging allo-HSCT after 2 months of combined therapy. Conclusion: CLL/SLL patients with TP53 aberration have poor prognosis because of rapid progression, drug resistance, etc. Ibrutinib combined with CAR-T cell therapy can quickly achieved complete remission.
