Effects of postoperative treatment with chemotherapy and cellular immunotherapy on patients with colorectal cancer

BACKGROUND The outcome of surgical treatment for colorectal cancer(CRC)remains unsatis-factory and warrants further exploration and optimization.AIM To clarify the impact of chemotherapy plus cellular immunotherapy[dendritic cell-cytokine-induced killer(DC-CIK)cell immunotherapy]on patients after CRC surgery and to explore the mediating variables.METHODS A total cohort of 121 patients who underwent CRC surgery between January 2019 and April 2022 were selected.The sample comprised a control group of 55 pa-tients who received the XELOX chemotherapy regimen and a research group of 66 patients who received XELOX+DC-CIK immunotherapy.We performed compa-rative analyses of the clinical and pathological data of the two groups,including efficacy(2-year disease-free survival[DFS]rate),the incidence of adverse events(diarrhea,myelosuppression,gastrointestinal reactions,and peripheral neuritis),serum levels of tumor markers[carcinoembryonic antigens and carbohydrate an-tigens(CA)19-9 and CA242],and T-cell subsets[cluster of differentiation(CD)3+,CD3+CD4+,CD3+CD8+,natural killer(NK),and NK T cells].We also conducted preliminary univariate and mul-tivariate analyses of the variables that affected the efficacy of the treatments.RESULTS We found a significantly higher 2-year DFS rate of treatment efficacy in the research group than in the control group,with a statistically lower incidence of adverse events.Both groups showed a reduction in serum tumor markers after treatment but there was no marked intergroup difference.After treatment,the various T-cell subgroup indicators in the control group were significantly lower than those in the research group.The indices of T-cell subsets in the research group showed no significant change from preoperative levels.Univariate analysis revealed a significant correlation between TNM staging,tumor differentiation,and the rates of nonresponse to treatment in CRC patients after surgery.Multivariate results indicated that the treatment approach significantly affected the efficacy of postoperative CRC treatment.CONCLUSION We concluded that XELOX+DC-CIK immunotherapy for postsurgical CRC patients offers reduced rates of treatment-induced adverse events,extended 2-year DFS,enhanced immunity,and increased physiological antitumor responses.

Side Effects of Chemotherapy in Cancer Patients and Evaluation of Patients Opinion about Starvation Based Differential Chemotherapy

Side-effects associated with the cancer chemotherapy limit the scope of chemotherapeutic drugs and no data was available about these side effects in Pakistan. Moreover starvation based differential chemotherapy has been proved to greatly reduce the side effects of chemotherapy depending on starvation time. The current study was conducted to survey the common side effects of the chemotherapeutic drugs and the role of starvation to reduce them. The study included total 100 subjects with multiple carcinomas. A comprehensive questionnaire about starvation inquiry, chemotherapy side effects and their basic information was filled by interviewers as told by patients. There were 48% patients with breast cancer and 11% with uterine cancer. Out of these patients 30%, 28%, 9% and 9% patients were agreed to starve for 12, 24, 36 and 48 hours respectively. The survey regarding the side effects of chemotherapy showed that 43% patients were suffering from headache, fatigue 90%, weakness 95%, hair loss 76%, nausea 77%, vomiting 75%, diarrhea 31%, abdominal cramps 40%, mouth sores 47%, dry mouth 74%, memory impairment 14%?and numbness 49%. Breast cancer is the most common cancer in Pakistan. Only 18% of the total patients were agreed to starve for more than one day. Chemotherapy-associated side effects vary greatly and it does not depend upon cancer type. But these side effects depend on multiple factors such as the type and dose of chemotherapeutic drug, patient’s health status and stage of cancer.

Tumor-feeding artery diameter reduction is associated with improved short-term effect of hepatic arterial infusion chemotherapy plus lenvatinib treatment

BACKGROUND Recently,hepatic arterial infusion chemotherapy(HAIC)plus lenvatinib has been frequently used to treat unresectable hepatocellular carcinoma(uHCC)in China.In the clinic,the hepatic arteries of some patients shrink significantly during this treatment,leading to improved short-term efficacy.AIM To investigate the relationship between the shrinkage of hepatic arteries and the short-term effect of HAIC plus lenvatinib treatment.METHODS Sixty-seven participants with uHCC were enrolled in this retrospective study.The patients received HAIC every 3 wk,followed by oral lenvatinib after the first HAIC course.Hepatic artery diameters were measured on CT before treatment and after 1 and 2 mo of treatment.Meanwhile,the changes in tumor capillaries were also examined on pathological specimens before and after 1 mo of treatment.The antitumor response after 1,3,and 6 mo of treatment was assessed using the modified Response Evaluation Criteria in Solid Tumors(mRECIST).The relationship between the changes in vessel diameters and the short-term effect of the combination treatment was evaluated by receiver-operating characteristic and logistic regression analyses.RESULTS The hepatic artery diameters were all significantly decreased after 1 and 2 mo of treatment(P<0.001),but there was no difference in the vessel diameters between 1 and 2 mo(P>0.05).The microvessel density in the tumor lesions decreased significantly after 1 mo of combination treatment(P<0.001).According to mRECIST,46,41,and 24 patients had complete or partial responses after 1,3,and 6 mo of treatment,respectively,whereas 21,21,and 32 patients had a stable or progressive disease at these times,respectively.Shrinkage of the tumor-feeding artery was significantly associated with the tumor response after 1,3,and 6 mo of treatment(P<0.001,P=0.004,and P=0.023,respectively);however,changes in other hepatic arteries were not significantly associated with the tumor response.Furthermore,shrinkage of the tumor-feeding artery was an independent factor for treatment efficacy(P=0.001,P=0.001,and P=0.002 and 1,3,and 6 mo,respectively).CONCLUSION The hepatic arteries shrank rapidly after treatment with HAIC plus lenvatinib,and shrinkage of the tumor-feeding artery diameter was closely related to improved short-term efficacy.

Cost-Effectiveness Analysis of Neoadjuvant Chemotherapy with Zoledronic Acid for HER2-Negative Breast Cancer in Japan: The JONIE1 Study

Objective: Zoledronic acid (ZOL) is a nitrogen-containing bisphosphonate that induces osteoclast apoptosis and inhibits bone resorption. Adding ZOL to neoadjuvant chemotherapy has been shown to have potential anticancer benefits in women with HER2-negative breast cancer. The objective of the present study was to investigate ZOL’s cost-effectiveness from the perspective of health care payers in Japan. Methods: A Markov model was developed to evaluate the costs and effectiveness associated with ZOL + chemotherapy (CTZ) and chemotherapy (CT) alone over a 10-year time horizon. Monthly transition probabilities were estimated according to JONIE1 (Japan Organization of Neoadjuvant Innovative Expert) Study data and an extrapolated Weibull model. Health outcomes were measured in quality-adjusted life years (QALYs). Costs were calculated using year-2018 Japanese yen (JPY) (1.00 US dollars (USD) = 110.4 JPY). Model robustness was addressed through one-way and probabilistic sensitivity analysis. The costs and QALYs were discounted at a rate of 2% per year. Results: In the base case, the use of CTZ was associated with a gain of 3.94 QALYs. The incremental cost per QALY of the CTZ gain was 681,056.1 JPY (6168.99 USD) per QALY. Conclusion: It is convincing that neoadjuvant CTZ for patients with breast cancer would be expected to have statistically significant clinical efficacy. Addition of ZOL to CT might be a cost-effective option compared with CT alone.
