ObjectiveTo investigate the role of chemoradiotherapy in the preoperative radiotherapy for locally advanced head and neck squamous cell carcinoma. MethodsFrom Sep. 2002 to Dec. 2008,totally 157 locally advanced head and neck squamous cell carcinoma (HNSCC) patients was assigned to preoperative concurrent chemoradiotherapy group ( n =81 ) or preoperative radiotherapy alone group ( n =76 ) randomly. The chemotherapy regimen was consisted of cisplatin 30 mg/m2, weekly. The radiotherapy in both groups was identical. The primary lesion will continue concurrent chemoradiotherapy or radiotherapy for those the tumor response was or nearly complete remission (CR) and those who refused surgery when evaluated at DT50 Gy, the others will receive surgery 1 month later if the tumor response was less than CR.For N3 patients, the planed neck dissection will be done. ResultsThe follow up rate was 98. 1％, 91patients followed up more than 5 years, there were 46 in concurrent chemoradiotherapy group and 45 in radiotherapy alone group. The rate of 5-year local control, overall survival, disease free survival and distant metastasis-free survival for preoperative concurrent chemoradiotherapy group and preoperative radiotherapy alone group were 63％ and 50％ ( x2 =0. 40,P =0. 528), 46％ and 38％ ( x2 =0. 48,P =0. 490) ,41％ and 35 ( x2 =0. 29, P =0. 593 ) ,76％ and 65％ ( x2 =3.38, P =0. 066 ) respectively. Subgroup analysis showed that the 2-years distant metastasis-free survival of preoperative concurrent chemoradiotherapy group and preoperative radiotherapy alone group were 88％ and 60％ ( x2 =5.99,P =0. 014). ConclusionsPreoper -ative concurrent chemoraidotherapy with the regimen of cisplatin 30 mg/m2 weekly did not improve the overall survival for locally advanced HNSCCwhen compared with preoperative radiotherapy alone.Preoperative concurrent chemoradiotherapy improved the distant metastasis-free survival of locally advanced hypopharyngeal and laryngeal carcinoma.

Objective: To investigate the clinical value of multimodal navigation-based virtual reality (MNVR) in the needle biopsy of intracranial eloquent lesions. Methods: From January 2016 to January 2017, 20 patients with intracranial deep-seated lesions involving eloquent brain areas underwent MNVR-aided needle biopsy at Department of Neurosurgery, People′s Liberation Army General Hospital. Preoperatively, MNVR was used to propose and revise the biopsy planning. Intraoperatively, navigation helped trajectory avoid the eloquent structures. Intraoperative MRI (iMRI) was performed to prove the biopsy accuracy and detect the intraoperative complications. Perioperative neurological status, iMRI findings, intraoprative complications, surgical outcome and pathological diagnosis were recorded. Wilcoxon rank-sum test was conducted to compare the preoperative and postoperative neurological scores. Results: MNVR helped revised 45%(9/20) initial biopsy trajectories, which would probably injury the nearby eloquent structures. Navigation helped biopsy trajectories spare the eloquent structures during the operation. No statistical difference was found between postoperative and preoperative neurological status, despite all the lesions were adjacent to eloquent areas. Additionally, 20 patients totally received 21 iMRI scanning. iMRI helped revise incorrect biopsy site in one case and detected intraoperative hemorrhage in another case, both of cases were treated immediately and effectively. No MNVR related adverse events and complications occurred. Conclusions MNVR-aided needle biopsy of intracranial eloquent lesions is a safe, novel and efficient biopsy modality. This technique is helpful to reduce the incidence of surgery related neurological deficits.

Objective:To identify the population who can obtain clinical benefit from concurrent chemoradiotherapy through the survival analysis during concurrent chemoradiotherapy in different subgroups.Methods:All data from a phase Ⅲ randomized controlled clinical trial were collected to compare the efficacy between preoperative concurrent chemoradiotherapy and preoperative radiotherapy from 2002 to 2012 in Cancer Hospital of the Chinese Academy of Medical Sciences. A total of 222 patients received radiation therapy with a median dose of 69.96 Gy (27.56-76.00 Gy). The cisplatin chemotherapy regimen was adopted and the median dose was 250 mg (100-570 mg). In total, 98 patients received intensity-modulated radiotherapy (IMRT). The survival analysis was conducted with Kaplan- Meier method and univariate analysis was performed with log-rank test. The multivariate prognostic analysis was conducted with Cox’s regression model. Results:The median follow-up time was 59 months (7-139 months). Among them, 104 patients were assigned in the chemoradiotherapy group and 118 patients in the radiotherapy alone group. The local and regional recurrence rates did not significantly differ between two groups (both P>0.05), while chemoradiotherapy tended to decrease the distant metastasis rate compared with the radiotherapy alone (14.4% vs. 24.6, P=0.058). Univariate analysis showed that concurrent chemoradiotherapy significantly increased the local recurrence-free survival in the early N stage subgroup ( P=0.009), and there was an increasing trend in patients aged≤55 years and female patients ( P=0.052, 0.066). The distant metastasis-free survival was significantly improved in T 4( P=0.048), N 3( P=0.005), non-IMRT treatment ( P=0.001) and hypopharyngeal carcinoma ( P=0.004) subgroups, there was an increasing trend in male ( P=0.064), high-and moderate-grade squamous cell carcinoma ( P=0.076) and non-surgical treatment subgroups ( P=0.063). Multivariate analyses showed that concurrent chemoradiotherapy significantly prolonged the progression-free survival and overall survival in patients aged≤55 years ( P=0.017 and 0.039), women ( P=0.041 and 0.039), high-and moderate-grade squamous cell carcinoma ( P=0.006 and 0.022), N 3 stage ( P=0.001 and 0.017), non-surgical treatment ( P=0.007 and 0.033) and non-IMRT treatment subgroups ( P=0.030 and 0.024), and it significantly increased the progression-free survival in patients with hypopharyngeal carcinoma ( P=0.022). Conclusion:Concurrent chemoradiotherapy can be actively delivered for young age, female, high-and moderate-grade squamous cell carcinoma, N 3 stage, non-surgical treatment and non-IMRT treatment patients.

Objective:To compare the effects of comprehensive treatment with different combinations of radiotherapy, chemotherapy and surgery on the survival of patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC).Methods:From September 2002 to May 2012, 222 patients were enrolled in a randomized controlled clinical trial to compare the clinical efficacy between preoperative radiotherapy and preoperative concurrent chemoradiotherapy. The chemotherapy was performed at the beginning of the radiotherapy, with cisplatin 30 mg/m 2 every week. Conventional radiotherapy or intensity-modulated radiotherapy (IMRT) was adopted. Clinical efficacy was evaluated during radiotherapy to 50 Gy in all patients. Whether surgery or original treatment regime was given was determined according to the clinical efficacy. The survival of different therapeutic methods was analyzed by Kaplan- Meier method. Results:The median follow-up time was 59 months (7-139 months). All patients were divided into four groups: radiotherapy group (R group, n=84), concurrent chemo-radiotherapy group (R+ C group, n=67), preoperative radiotherapy group (R+ S group, n=34) and preoperative concurrent chemoradiotherapy group (R+ C+ S group, n=37). The 5-year overall survival rates were 32%, 44%, 51%, and 52%, respectively (R+ C+ S group vs. R group, P=0.047). The 5-year progression-free survival rates were 34%, 48%, 49%, and 61%, respectively (R+ C Group vs. R group, P=0.081; R+ C+ S group vs. R group, P=0.035). The 5-yeal distant metastasis-free survival rates were 70%, 85%, 65%, and 73%, respectively (R+ C group vs. R+ S group, P=0.064; R+ C group vs. R+ S group, P=0.016). Conclusions:Compared with radiotherapy alone, comprehensive treatment with different combinations can improve the long-term survival of LA-HNSCC patients. Radiotherapy combined with chemotherapy has a tendency to improve the distant metastasis-free survival rate, The optimal comprehensive treatment modality that improves the overall survival of LA-HNSCC patients remains to be explored.

Objective:To evaluate the incidence, clinical characteristics and prognosis of second primary malignancies (SPMs) among patients with hypopharyngeal carcinoma (HPC) in real-world analysis.Methods:A total of 594 HPC patients admitted to Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from 2010 to 2018 were retrospectively analyzed.The incidence and clinical characteristics of HPC patients complicated with SPMs were analyzed. Clinical efficacy was compared among different groups.Results:With a median follow-up time of 66.9 months, SPMs were present in 36.4% (216/594) of HPC patients: 22.2% (132/594) were synchronous and 14.1% (84/594) were metachronous. The upper aerodigestive tract was the most common involved region. Compared with patients without SPMs, patients with synchronous and metachronous carcinoma in situ had similar 5-year overall survival (OS) of 42.2% vs. 44.5% ( P=0.958) and 62.2% vs. 44.5% ( P=0.240), respectively. Patients with synchronous invasive SPMs had a worse 5-year OS of 27.2% vs. 44.5% in their counterparts without SPMs ( P=0.001). Patients with metachronous invasive SPMs had similar 5-year OS of 50.2% vs. 44.5% in their counterparts without SPMs ( P=0.587). SPMs accounted for 42.5% of total death in metachronous invasive SPMs group. Conclusions:Patients with HPC have a high probability of developing SPMs. Moreover, the incidence of complicated with esophageal/gastric carcinoma in situ or metachronous SPMs exerts no effect on prognosis, while the occurrence of synchronous SPMs significantly affectes the prognosis of patients. However, the incidence of SPMs is still one of the main death causes in metachronous invasive SPMs group.
