For those patients with gastric cancer, surgical treatment may be the only option for therapy. Here, we present the first case of gastric cancer with severe and medically refractory ITP treated by radical resection of the gastric cancer and splenectomy. CASE SUMMARY A 54-year-old female patient was admitted to our surgical department with a 2 mo history of decreased appetite, nausea, vomiting, and weight loss, which progressed to difficulty in feeding 3 d prior to her visit. According to her medical history, she was diagnosed with refractory ITP [platelets(PLT), 3000-8000/μL] 10 years ago. After admission, the patient underwent a splenectomy and a distal subtotal gastrectomy(D2 radical resection) with Roux-en-Y reconstruction simultaneously. She had an uneventful postoperative course with a slight increase in her PLT count. This case is unique in terms of the patient's complication of severe and medically refractory ITP.CONCLUSION Simultaneous splenectomy, preoperative PLT transfusion, and early enteral nutrition were important treatment methods for helping this patient recover.展开更多

The etiologyof thrombocytopenia in patients with cancer and liver injury (TCLI) is complicated. Managing cancertherapy-induced thrombocytopenia has gradually become standardized, and managing liver injuryassociatedthrombocytopenia has become more effective with the approval and marketing of relevantdrugs. However, the optimal strategy for managing thrombocytopenia in patients with cancer and liverinjury remains unclear, and the superposition of thrombocytopenia and liver injury further increasesthe difficulty of cancer treatment. Therefore, the Committee of Cancer Support Therapy of the ChineseAnti-Cancer Association has organized experts to analyze and discuss relevant literature to form aChinese expert consensus on managing thrombocytopenia in patients with cancer and liver injury(2022 Edition) to guide clinical practice.展开更多

Rapid diagnosis and precise distinction from other forms of TMA is crucial for appropriate therapy, which aims at treating the underlying malignancy. However, the prognosis of patients with cancer-related(CR)-MAHA is limited. To date, less than 50 patients with gastric cancer and CRMAHA have been reported, mainly as single case reports, and detailed information on treatment strategies and outcome are scarce. We analyzed the characteristics and outcomes data of CR-MAHA patients with gastric cancer treated at our center between 2012 and 2019.AIM To gain knowledge about CR-MAHA and the course of disease.METHODS We retrospectively analyzed patients using an institutional prospectively maintained database. Patients who had CR-MAHA but other cancer types or cancer of unknown primary were excluded. The basic requirements for inclusion were: Histologically proven gastric adenocarcinoma;and clinical diagnosis of hemolytic anemia with schistocytes with or without thrombocytopenia. The observation period for each patient started with the first day of documented symptoms. The follow-up period for this analysis ended on February 1, 2020.RESULTS We identified eight patients with a median age of 54 years. Histologically, all patients had(partial) diffuse subtypes of gastric adenocarcinoma with partial or complete signet cell morphology. All patients had metastatic disease and one patient had a microsatellite instability-high(MSI-H) tumor. In three patients, clinical signs of MAHA preceded the diagnosis of cancer, and in two patients, CRMAHA indicated recurrent disease. All patients had severe hemolytic anemia and thrombocytopenia. Six patients experienced severe bone pain, and five patients had dyspnea. Systemic, 5-fluorouracil-based combination chemotherapy was initiated in six patients, which resulted in rapid initial response with significant improvement of clinical symptoms and blood values. Progression-free survival(PFS) of the whole cohort was 1.9 wk and median overall survival(OS) was 1.9 wk. For patients with chemotherapy, PFS was 9.0 wk and OS was 10.3 wk. The patient with the MSI-H tumor has been undergoing immunotherapy for more than 3 years.CONCLUSION The benefit of chemotherapy in CR-MAHA patients is limited. Immunotherapy for patients with MSI-H tumors may lead to long-term tumor control even in CRMAHA patients.展开更多

Methods： Univadate and multivariate logistic regression analyses were performed to evaluate correlations between common toxicities and binary ORR in 106 mCRC patients from a prospective cohort treated with irinotecan based regimens. Results： The most frequent severe toxicities （Grade 3/4） were as follows： neutropenia （27.4%）, diarrhea （16.9%）, leucopenia （12.6%）, vomiting （3.2%） and thrombocytopenia （2.1%）. Thrombocytosis was observed in 25 （26.3%） patients. ORR was 25.3%. Thrombocytopenia （P = 0.014）, line of chemotherapy （P = 0.028） and thrembocytosis （P = 0.033） were correlated with ORR in univariate analysis. In multivariate analysis, thrombocytopenia （odds ratio [OR] = 8.600, 95% confidence interval [CI] = 1.705-43.385, P = 0.009） and first line chemotherapy （OR = 5.155, 95% CI = 1.153-23.256, P = 0.032） positively related to ORR. Conclusion： Threm- bocytopenia may be an indicator of ORR in mCRC patients treated by irinotecan plus 5-fluorouracil/capecitabine. Evidence is not strong enough to prove that irinotecan based regimens-induced diarrhea, leucopenia, neutropenia or vomiting is associ- ated with ORR.展开更多
