  • Clinical Toxic and Adverse Reaction and Pathological Observation of Regional Arterial Perfusion Chemotherapy During Radial Resection of Gastric Cancer

    Objective To observe the drug distributional characteristics after regional arterial perfusion chemotherapy (RAC) during gastric cancer radical resection, postoperative histopathological change and clinical toxic and adverse reactions. Methods According to the indications of RAC, 60 patients admitted in this department from September 2007 to November 2008 were included and divided into treated group and control group randomly. Treated group underwent the treatment of RAC with the 100 ml perfusion fluid including 5-FU (1 000 mg/m2), MMC (10 mg/m2) and 2 ml methylene blue injection by which the control group were not treated. Then the methylene blue distributional characteristics during operation, postoperative histopathological changes of tumors and clinical toxic and adverse reactions were observed. Results In the treated group, after RAC with injection contained methylene blue by primary supply arterial, the tumor region colored immediately and then dropped slowly, but it presented blue during whole operation. After operation, light microscope examination revealed a mild change of karyopyknosis, nuclear swelling, coagulation of cytoplasm in cancer cells, mild hydropsia of intercellular substance, invasion of inflammatory cells and mild vasculitis in some cases. Transmission electron microscope showed that nuclear swelling or coagulation, nuclear heterochromatin agglutination, nuclear-week gap expansion, mitochondrial swelling, endoplasmic reticulum expansion, and Golgi complex expansion. AST of treated group increased apparently on the first day (Plt;0.01), and recovered normal on the third day (Pgt;0.05). There was no significant difference between the two groups in renal function, ALT, ALP, GGT, LDH of liver function, medullary restraining, ECG by bed or reaction of gastrointestinal tract (Pgt;0.05). And stomal leak was not found in two groups. Conclusions The RAC during radical resection of gastric cancer enables gastric tumor to expose to therapeutics during whole operation and depresses the activity of cancer cells. Its clinical toxicity is little, so it can be used as an important supplementary means to prevent intraoperational extension and postoperative recurrence.

  • Anesthetic Quality of Epidural Anesthesia with General Anesthesia Applied for Surgery of Rectal Cancer

    Objective To explore anesthetic quality of epidural anesthesia with general anesthesia applied for surgery of rectal cancer. Methods One hundred and seventy-eight patients who were diagnosed as rectal cancer and received operation in the Central Hospital of Bazhong City from June 2010 to June 2012 were included retrospectively. These patients were divided into two groups according to the type of anesthesia, and the patients who received general anesthesia only were defined as group A, the patients who received epidural anesthesia with general anesthesia were defined as group B. The anesthetic quality and anesthetic adverse reaction were observed in two groups. Results The differences of baseline characteristics in two groups were not significant (P>0.05). The difference of anesthetic quality in two groups was not significant (P>0.05). In terms of anesthetic adverse reaction, the incidence rate of hypertension, hypotension,tachycardia, or postoperative nausea and vomiting of the group B was significantly lower than those of the group A (P<0.05). The incidence rate of bradycardia, premature ventricular contractions, or time of gastrointestinal function recovery had no significant differences (P>0.05). There was no nerve dysfunction of lower limb in two groups. Conclusion Epidural anesthesia with general anesthesia applied for surgery of rectal cancer as compared with general anesthesia only not only has the same anesthetic quality, but also has obvious advantages in decreasing anesthetic adverse reaction.

  • Correlation between adverse reactions and curative effect in neoadjuvant chemotherapy for breast cancer

    ObjectiveTo analyze the relationship between adverse reactions and curative effect in neoadjuvant chemotherapy, this study is to explore whether the adverse reactions of chemotherapy can indirectly predict the efficacy of chemotherapy, so as to give a new definition of adverse reactions of chemotherapy.MethodsThe clinical data of 64 patients with neoadjuvant chemotherapy for breast cancer (after 4 cycles of TAC regimen) were retrospectively analyzed. The adverse reactions (weakness, nausea, vomiting, alopecia, myelosuppression, cardiotoxicity) during chemotherapy were counted. At the same time, the evaluation of chemotherapy efficacy was carried out according to the RECIST1.1 standard, and the relationship between the degree of adverse reactions of chemotherapy and the curative effect was analyzed one by one. Then, according to the severity of adverse reactions, adopting the form of scoring to assign the value, and use Pearson correlation analysis to clarify the specific relationship between adverse reactions and curative effect. Finally, four subgroups of Luminal A, Luminal B, Her2+ and Sanyin were determined according to molecular typing, and the relationship between adverse reactions and therapeutic effects among different subgroups was analyzed.ResultsThere was no difference in the adverse reactions of chemotherapy in neoadjuvant chemotherapy patients of different ages (correlation coefficient r fluctuated between –0.079 and –0.164, P value fluctuated between 0.195 and 0.533). The patients with high scores of adverse reactions showed relatively good efficacy (r=0.587, P<0.01). There was no significant correlation between fatigue, nausea and vomiting and efficacy (r=0.199, P=0.144; r=0.127, P=0.144). Among the adverse reactions, there was a significant positive correlation between alopecia, myelosuppression, cardiotoxicity and efficacy (r=0.532, r=0.621, r=0.422, all P<0.01). The above correlation was verified in the Luminal A subgroup (r=0.559, P<0.007).ConclusionsThe severity of adverse reactions in neoadjuvant chemotherapy can predict the efficacy of chemotherapy. To a certain extent, the heavier adverse reactions, the better the chemotherapy effect. Hair loss, myelosuppression, and cardiotoxicity have a clearer effect on efficacy in several common adverse reactions.

  • Risk analysis of myocarditis induced by immune checkpoint inhibitors: a real-world study based on the open FDA database

    ObjectiveTo investigate the risk of myocarditis caused by immune checkpoint inhibitors (ICI). MethodsThe adverse reaction (ADR) reports on myocarditis caused by atelizumab, duvalizumab, pabolizumab, and navulizumab were downloaded from the FDA Adverse Event Reporting System (FAERS) from January 1, 2014 to September 30, 2022. The relevant analysis was conducted on the gender, age, medication dosage, and occurrence time of ICI related myocarditis patients. ResultsA total of 1 892 reports of myocarditis induced by ICI were included. The proportion of myocarditis caused by ICI was higher in males than in females (1.9∶1). The incidence of myocarditis in patients with basic diseases such as diabetes and heart disease, and in the age group 65-75 was relatively high. The incidence of myocarditis caused by navulizumab was high within 30 days with the use of conventional doses, and that of the other three drugs were high within 31 to 90 days. And the incidence of myocarditis is higher when used in combination than when used alone. ConclusionDifferent varieties of ICI can lead to the occurrence of myocarditis, and male, elderly, underlying diseases, and combination therapy may be risk factors for myocarditis caused by ICI.

  • Adverse renal reactions of tyrosine kinase inhibitor drugs: a systematic review

    ObjectiveTo systematically review the renal adverse reactions of tyrosine kinase inhibitors (TKI). MethodsPubMed, EMbase, Cochrane Library, CNKI, WanFang Data and CBM databases were electronically searched to collect randomized controlled trials (RCTs) on the incidence of renal adverse reactions of TKI from inception to March 30, 2023. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.4 software. ResultsA total of 19 RCTs involving 10 141 patients were included. The results of meta-analysis showed that compared with placebo or blank control, gefitinib, ranvartinib, cabotinib, vandetanib, pazopanib, arotinib, apatinib, and acitinib could lead to an increased risk of proteinuria events, while sildenib did not increase the risk of proteinuria in patients. Anlotinib could increase the risk of hematuria. Vandetanil increased the risk of acute kidney injury. Gefitinib, ranvartinib and apatinib could increase the risk of grade 3-4 renal adverse reactions. ConclusionCurrent evidence shows that TKI drugs may cause renal damage in patients, and proteinuria is the most common. Vandetanil can cause acute kidney injury, gefitinib, ranvartinib and apatinib are more nephrotoxic. The renal adverse reactions of neratinib, ibutinib and sildenib are relatively few.
