Objective To explore the value of chemosensitivity assay in vitro on breast cancer. Methods In vitro chemosensitivity of 6 species of chemotherapeutic agents applied to 38 cases of breast cancer patients were detected by tissue culture-end point staining-computer image analysis (TECIA). Results The sensitivity to chemotherapeutic agents commonly used in the breast cancer level from high to low was as follow: Doxorubicin (ADM), Paclitaxel (TAX), Vinorelbine (NVB), Cyclophosphamide (CTX), Cisplatin (DDP) and Fluorouracil (FU). Conclusion Drugs sensitivity experiment of cancer in vitro by TECIA has an important value to instruct clinical medication and individual chemotherapy for breast cancer.
Pre-and postoperative perfusion of thermochemotherapy was used in 25 cases of advanced malignant tumors of digestive tract.There were on significant changes in hepatic and renal functions after perfusions.The erythrocyte,leukocyte and platelet counts reduced in the second and third week after the beginningof perfusion,but rose up in the 4th week.A 2-year follow-up revealed that 23 patients were still alive without recurrence or metastases except 2cases died in the 6th and the 9th month after treatment.We claim that intraperitoneal thermochemotherapy is a simple and safe method. A prospective study is still necessaryin deciding the dose and course.
ObjectiveTo study value of long noncoding RNA H19 and HOTTIP in plasma in predicting efficacy of neoadjuvant chemotherapy (NAC) for resectable locally advanced gastric cancer. MethodsForty patients with T3–4aN+M0 gastric cancer and 40 patients with benign gastric diseases treated in the Yantai Yuhuangding Hospital Affiliated to Qingdao University from August 2020 to May 2021 were prospectively included. The expressions of H19 and HOTTIP in the plasma of gastric cancer and benign gastric diseases patients without any treatment after admission were detected before treatment (CAPEOX regimen was used in the patients with gastric cancer), then which were detected after 2 NAC courses for patients with gastric cancer. Meanwhile, some clinical items were detected and the efficacy of NAC was evaluated. The complete remission (CR) and partial remission (PR) were classified as objective remission, CR, PR, and disease stability were classified as disease control. The expressions of H19 and HOTTIP between the different patients were compared and the receiver operating characteristic (ROC) curve was used to evaluate their values in the diagnosis of resectable locally advanced gastric cancer. ResultsThere were 13 cases of T downstaging and 27 cases of T non-downstaging and 25 cases of objective remission and 35 disease control after NAC. The median relative expression levels of H19 and HOTTIP before NAC in the patients with gastric cancer were higher than those in the patients with benign gastric diseases (H19: 1.42 versus 0.98, Z=–3.835, P<0.001; HOTTIP: 2.15 versus 1.04, Z=–5.062, P<0.001), and which were in the patients with T downstaging and disease control were lower than those in the patients with T non-downstaging and 5 cases of disease progression (For T staging, H19: 1.12 versus 1.54, Z=–2.960, P=0.002; HOTTIP: 1.49 versus 2.30, Z=–2.310, P=0.019. For efficacy of NAC, H19: 1.39 versus 2.48, Z=–3.211, P<0.001; HOTTIP: 1.96 versus 3.25, Z=–2.393, P=0.014). The median relative expressions of H19 and HOTTIP after NAC were lower than those before NAC in the patients with gastric cancer (H19: 1.12 versus 1.42, Z=–3.965, P<0.001; HOTTIP: 1.30 versus 2.15, Z=–4.839, P<0.001). There were no significant differences in the changes of H19 and HOTTIP before and after NAC between the patients with T downstaging and T non-downstaging, and between disease control and disease progression (P>0.05). The areas of ROC curve of H19, HOTTIP, and combination of H19 and HOTTIP in diagnosis of resectable locally advanced gastric cancer were higher than 0.7. ConclusionsLncRNA H19 and HOTTIP might be potential tumor markers in gastric cancer, and their diagnostic values for resectable locally advanced gastric cancer are higher. Gastric cancer patients with low expressions of H19 and HOTTIP in plasma might be more sensitive to NAC.
Six patients with moderate to advanced primary carcinoma of the liver were treated in this hospital with perfusion chemotherapy and embolization through the regional portal vein under the guidance of B-ultrasongraph rather than (with) operatie catheteization of the portal vein. The results show that all the tumor masses were reduced in size after the treatment (1.2-3.2cm, average value 1.9cm). It might be a new way for treating the primary carcinom of liver. The detailed procedure is descibed and the effects are also discussed in this article.
Objective To observe the life quality and the immune function of colorectal cancer patients treated by huaier granule combined with FOLFOX4 chemotherapy. Methods A total of 76 cases of colorectal cancer with chemotherapy indications were divided into two groups at random. Huaier granule and FOLFOX4 chemotherapy was applied in trial group， meanwhile， placebo and FOLFOX4 chemotherapy in control group. The changes of life quality， common condition， and immune state in two groups before and after treatment were abserved. Results The effective rate in the trial group was 92.1％ （35/38）， and in the control group was 65.8％ （25/38）， χ2=7.91， P＜0.005. The life quality improving rate in the trial group was 78.9％ （30/38）， and in the control group was 31.6％ （12/38）， χ2=6.33， P＜0.05. The CD3 increase rate in the trial group was 65.8％（25/38）， and in the control group was 23.7 ％ （9/38）， χ2=7.96， P＜0.005， the CD4/CD8 increase rate in the trial group was 68.4 ％（26/38） , and in the control group was 28.9％ （11/38）， χ2=10.53， P＜0.005. Conclusions Huaier granule can significantly improv the clinical symptoms, life quality, and immune state. Huaier granule combined with FOLFOX4 chemotherapy is a new effective scheme to cure colorectal cancer， is worth further generalization．
Objective To explore the accuracy of contrast-enhanced magnetic resonance imaging (MRI) in predicting pathological complete remission (pCR) in breast cancer patients after neoadjuvant therapy (NAC). Methods The clinicopathological data of 245 patients with invasive breast cancer who had completed the surgical resection after NAC in the Affiliated Hospital of Southwest Medical University from March 2020 to April 2022 were collected retrospectively. According to the results of hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2) detected by immunohistochemistry, all patients were divided into four subgroups: HR+/HER2–, HR+/HER2+, HR–/HER2+ and HR–/HER2–. The value of MRI in evaluating the efficacy of NAC was analyzed by comparing the postoperative pathological results as the gold standard with the residual tumor size assessed by preoperative MRI. Meanwhile, the sensitivity, specificity and positive predictive value (PPV) of pCR predicted by the evaluation results of enhanced MRI were analyzed, and further analyzed its predictive value for pCR of different subtypes of breast cancer. Results There were 88 cases (35.9%) achieved radiological complete response (rCR) and 106 cases (43.3%) achieved pCR in 245 patients. Enhanced MRI in assessing the size of residual tumors overestimated and underestimated 12.7% (31/245) and 9.8% (24/245) of patients, respectively. When setting rCR as the MRI assessment index the specificity, sensitivity and PPV were 84.2% (117/139), 62.3% (66/106) and 75.0% (66/88), respectively. When setting near-rCR as the MRI assessment index the specificity, sensitivity and PPV were 70.5% (98/139), 81.1% (86/106), and 67.7% (86/127), respectively. The positive predictive value of both MRI-rCR and MRI-near-rCR in evaluating pCR of each subtype subgroup of breast cancer was the highest in the HR–/HER2+ subgroup (91.7% and 83.3%, respectively). In each subgroup, compared with rCR, the specificity of near-rCR to predict pCR decreased to different degrees, while the sensitivity increased to different degrees. Conclusions Breast contrast-enhanced MRI can more accurately evaluate the efficacy of localized breast lesions after NAC, and can also more accurately predict the breast pCR after NAC. The HR–/HER2+ subgroup may be a potentially predictable population with pCR exemption from breast surgery. However, the accuracy of the evaluation of pCR by breast enhancement MRI in HR+/HER2– subgroup is low.
ObjectiveTo evaluate the efficacy of 30% and 50% dose photodynamic therapy (PDT) for acute central serous chorioretinopathy (CSC). MethodsA retrospective cohort study. Ninety-two eyes of 88 patients with CSC, diagnosed by best corrected visual acuity (BCVA) of logarithm of the minimum angle of resolution (logMAR), indirect ophthalmoscope, fundus colorized photography, fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA)and optical coherence tomography (SD-OCT) treated with 30% and 50% doses of verteporfin respectively between March 2007 and August 2013, were enrolled. The eyes were divided into 50% dose group (49 eyes) and 30% dose group (43 eyes). The differences of age (t=-1.45), gender (χ2=0.011), eyes (χ2=2.140), mean logMAR BCVA (t=-0.40), mean central retinal thickness (CRT) and the maximum thickness of serous retinal detachment (SRD) between two groups were not significant (P > 0.05). The difference of spot size between two groups was significant (t=-2.84, P < 0.05). The follow-up time was ranged from 6 to 68 months, with a mean of (17.16 ±11.30) months. The difference of follow-up between two groups was significant (P > 0.05). The BCVA, cure rate, recurrence rate and the changes of CRT and maximum SRT were observed by SD-OCT. ResultsThe subretinal fluid (SRF) of 31 eyes (72.09%) in the 30% dose group and that of 47 eyes (95.92%) in the 50% dose PDT group was absorbed completely respectively. The cure rates in the 30% dose PDT group was significantly less than that in the 50% dose group (χ2=10.077, P=0.020). There was a significant negative association between the cure rate and spot size by Logistic regression (odds ratio > 1, P=0.040). The difference of changes in the BCVA of logMAR in 50% dose group was better than that in 30% dose group after more than 12 months after PDT (P=0.036). On 3, 6, 12 and more than 12 months after PDT, the difference in CRT in 50% dose group and 30% dose group were not statistically significant (P=0.068, 0.060, 0.082, 0.067). The difference in maximum thickness of SRD was not statically significant (P > 0.05). SRF was appeared in 8 eyes (25.81%) of 31 eyes in the 30% dose group, while SRF was appeared in 1 eye (2.13%) of 47 eyes in the 50% dose group. The recurrence rate of 30% dose group was much higher than that of 50% dose group (P < 0.05). ConclusionsFor acute CSC treated by PDT, the curative effect of 50% dose group is better than the 30% dose group.

Objective To systematically review the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) and sorafenib (SORF) separately or combined in the treatment of advanced hepatocellular carcinoma (HCC). MethodsWe searched the PubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases for studies on HAIC and SORA separately or in combination in the treatment of advanced HCC from inception to November 1, 2021. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.3 software. ResultsA total of 21 studies involving 2 501 patients were included. The results of meta-analysis showed that the overall survival (OS) (HR=0.46, 95% CI 0.25 to 0.87, P=0.02), objective response rate (ORR) (OR=4.00, 95%CI 2.74 to 5.85, P<0.000 01) and disease control rate (DCR) (OR=2.20, 95%CI 1.30 to 3.75, P=0.004) were higher in the HAIC group than the SORF group, while the incidence of adverse reactions was not increased. However, HAIC combined with SORF showed no significant difference in OS, ORR, DCR or progression-free survival (PFS) compared with SORF alone. Moreover, combined treatment increased the adverse reactions of blood system. Conclusion The current study suggests that HAIC can improve OS, ORR and DCR in patients with advanced HCC; however, there is no additional benefit when combining SORF with HAIC. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
