OBJECTIVE To analyze the value of modified sinus CT score in olfactory function evaluation before and after functional endoscopic sinus surgery in chronic rhinosinusitis with nasal polyps(CRSwNP). METHODS Fifty-four patients who underwent functional endoscopic sinus surgery for CRS with nasal polyps were enrolled in this prospective study by inclusion criteria and exclusion criteria. T&T methods and olfactory function VAS were used to analyze the subjective olfactory function and were performed preoperatively and at 6 months after surgery. In modified sinus CT score, middle turbinate and superior turbinate associated olfactory cleft areas were used to evaluate the anterior olfactory cleft score(AOCS) and posterior olfactory cleft score(POCS). Sinus CT scans Lund-Mackay scores were also collected before surgery. The correlation between the status of the olfactory cleft on CT, Lund-Mackay score and the preoperative and postoperative olfactory results were investigated.RESULTS Among 54 patients, there were 36 male and 18 female, with average age of 47.9 years old(from 24 to 67 years). There were 30 patients followed 6 months after surgery. The findings of olfactory cleft opacification and the CT Lund-Mackay scores had a positive correlation with preoperative olfactory results(P<0.001). The olfactory cleft opacification showed a stronger correlation with the preoperative olfactory results than the CT Lund-Mackay score. The AOCS was more significantly correlated with the postoperative olfactory results than the other parameters.CONCLUSION Preoperative CT findings, especially the anterior portion of the olfactory cleft had a statistically significant association with the postoperative olfactory results in patients with CRS with nasal polyps.

Objective:To explore the efficacy and safety of 192Ir three-dimensional brachytherapy combined with intensity-modulated radiotherapy in patients with unresectable advanced obstructive extrahepatic cholangiocarcinoma. Methods:A retrospective analysis of the efficacy and safety of 18 patients with unresectable advanced malignant obstructive extrahepatic cholangiocarcinoma admitted to the Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine in Hebei province from January 2014 to January 2018.All patients were pathologically confirmed and received biliary stent implantation, followed by sequential intensity-modulated radiotherapy and 192Ir three-dimensional brachytherapy.The clinical data of all patients were collected, including gender, age, clinical stage, adverse reactions, brachytherapy dose-volume parameters, changes in bilirubin levels before and after treatment, evaluation of efficacy, local control rate and survival rate. Results:All patients successfully completed the treatment.Re-examination was conducted one month after the combined treatment, of the 18 patients, 16 had partial remission (PR) and 2 were stable(SD). Among them, 14 patients had tumor shrinkage after brachytherapy compared with intensity-modulated radiotherapy, and 4 patients showed no significant change.The 6-month local control rate (LC) was 94.4% (17/18). The 1-year survival rate was 55.6% (10/18), and the 2-year survival rate was 38.9% (7/18). Statistical analysis showed that after combined treatment, total bilirubin and direct bilirubin were significantly reduced, and jaundice symptoms were significantly relieved.The adverse reactions of the patient were nausea, vomiting, fever, biliary tract infection, etc.There were no adverse reactions of grade 3 or above.Conclusions:192Ir three-dimensional brachytherapy combined with intensity-modulated radiotherapy in patients with inoperable advanced extrahepatic cholangiocarcinoma has a good local control rate and tolerable adverse reactions, but the impact on long-term survival requires a large sample of controlled studies.

Objective: To investigate the effect of Utrecht applicator on dosimetrics of targets and OARs in brachytherapy for advanced cervical cancer. Methods: Data of patients with locally advanced cervical cancer who received brachytherapy with Utrecht Source Applicator from 2017 to 2018 in the Department of Radiotherapy, Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine, Hebei province, were collected. The original plan was intracavitary /interstitial brachytherapy (IC/IS-BT). With the original contour and prescription dose unchanged, the implantation was removed and new intracavitary brachytherapy (IC) plan was designed. The dosimetric parameters of IC/IS plan and IC plan were compared and analyzed, and the effect of IS implantation on dose was evaluated. Results: The D₉₀ of HR-CTV was (88.68±1.84) Gy in IC/IS group and (85.54±0.54) Gy in IC group, with significant difference(t=6.200, P<0.05). In addition, conformity index of the IC/IS plan was significantly higher than that of the IC plan (IC/IS: 0.58±0.08, IC: 0.43±0.05; t=1.010, P<0.05). In terms of OAR, there was no significant difference in dosage between the two groups (P>0.05). Conclusions For the brachytherapy of locally advanced cervical cancer, the use of Utrecht Source Applicator can satisfy the prescription dose coverage. Adding IS insertion needle can improve the optimization space of the plan. Without exceeding the dose limit of OAR, the radiation dose to HR-CTV can be significantly increased, and the uniformity of dose distribution can be improved as well.

Pelvic insufficiency fracture (PIF) is a late complication which is not fully understood after radiotherapy and chemotherapy for cervical cancer and is easily misdiagnosed as bone metastasis. Previous clinical trials focused on the incidence, time and location of PIF, while the analysis of potential risk factors mainly emphasized the clinical characteristics of patients. There were few studies analyzing the correlation between treatment factors and the incidence. The damage of pelvis bone, especially the sacrum, after radiotherapy is mainly related to irradiation mode and dose. In this article, the radiotherapy technology, the formulation of bone-conserving radiotherapy plan, the dose-volume parameters of external irradiation and intracavitary brachytherapy, and the correlation between chemotherapy and this disease were reviewed. In the future, according to the advantages of precision radiotherapy technology, it is necessary to optimize the bone preservation plan, reduce the irradiation range and dose of sacrum and pelvis, and then reduce the incidence of PIF, which needs further clinical trials and practice to verify.

Brachytherapy has played an important role in localized prostate cancer. High-dose-rate brachytherapy has evolved over the decades, as either monotherapy or in combination with external beam, it offers many advantages over other treatment alternatives. Precise control over dose delivery allows for focal dose escalation while sculpting dose around organs at risk to maintain excellent tolerance. The high dose per fraction exploits the low α/β ratio of prostate cancer and triggers transcriptional changes in the tumor genome, thereby enhancing radiation sensitivity. In this article, the development, patient selection, application of techniques, clinical efficacy and adverse events for high-dose-rate brachytherapy were summarized.
