  • Research progress on conversion chemotherapy of stage Ⅳ gastric cancer

    ObjectiveTo explore feasibility and security of conversion chemotherapy of stage Ⅳ gastric cancer.MethodThe research progresses of conversion chemotherapy of stage Ⅳ gastric cancer were summarized by reading relevant literatures.ResultsThe prognosis of stage Ⅳ gastric cancer was poor, its correct treatment strategy was still controversial. At present, the palliative chemotherapy and targeted therapy were mainly used for it. In recent years, the development of chemotherapeutic drugs had improved the survival of some patients who showed the excellent chemotherapy response rate and subsequently undergone surgery, which promoted the derivation of the concept of conversion therapy. For the patients with initial unresectable stage Ⅳ gastric cancer, these patients could get better pathological reaction and then perform R0 operation through the comprehensive measures such as the preoperative chemotherapy, so that the patients could acquire relatively longer survival time. The previous studies indicated that the single unresectable factor, chemotherapy response rate, and whether R0 resection were the important predictors of prognosis for patients with stage Ⅳ gastric cancer.ConclusionsConversion therapy is still at initial stage. Different conversion chemotherapy regime has different response rate. Moreover, expert consensus on case selection, chemotherapy regimen are absent due to lack of high-quality, multi-center, large-sample data. So higher levels of clinical randomized controlled trials are needed to support and guide this practice. In a word, conversion therapy of stage Ⅳ gastric cancer requires multi-disciplinary efforts to carry out an optimal classification to select out suitable candidates, which may provide efficient guidance for comprehensive treatment for stage Ⅳ gastric cancer.

  • Conversion therapy of giant liver cancer: a case of MDT discussion

    Objective To investigate the value of multidisciplinary team (MDT) diagnosis and treatment model in the conversion therapy of liver cancer. Method The clinical data of a patient with high-risk giant liver cancer of the right liver who was admitted to People’s Hospital of Leshan in April 2019, and who was successfully conversion therapy and safely underwent hepatectomy after MDT discussion was retrospectively analyzed. Results A 62 years old male patient was admitted to our hospital with “abdominal distension for more than 1 month, and liver mass was found for 10 days”. The relevant auxiliary examinations were perfected. The patient was diagnosed as huge primary hepatocellular carcinoma in the right liver. One-stage surgical resection cannot be performed safely due to the huge tumor. After MDT discussion, transcatheter arterial chemoembolization (TACE) combined with sorafenib targeted therapy was decided to reduce the lesions, and two-stage surgical resection was performed safely after conversion therapy. After two cycles of TACE combined with sorafenib targeted drug therapy, MDT discussed the feasibility of safe surgical resection, and underwent fluorescence-guided laparoscopic right posterior lobectomy. The postoperative pathological examination revealed moderately differentiated hepatocellular carcinoma. The patient recovered and was discharged from the hospital one week later. Outpatient followed-up for 32 months showed no obvious abnormality. Conclusions MDT discussion can formulate a more individualized treatment plan, improve the conversion rate and resectable rate of advanced liver cancer, and has important value in the diagnosis and treatment of advanced liver cancer.
