ABSTRACT

Objective To analyze the efficacy and safety of CyberKnife combined with temozolomide (TMZ) in treatment of brain metastasis of non-small cell lung cancer (NSCLC). Methods From March 2013 to March 2016, 62 NSCLC patients with brain metastases in department of oncology of the 187th Hospital of PLA were divided into two groups according to the random number table method, the CyberKnife combined with TMZ group (CyberKnife + TMZ group, 31 cases) and simple CyberKnife group (CyberKnife group, 31 cases). Hypofractionated radiation of CyberKnife was given 18-36 Gy in 1-5 fractions of 5-25 Gy. CyberKnife+ TMZ group was given temozolomide 150 mg·m-2·d-1 for 5 days in first cycle, then every 28 days they received temozolomide therapy from the second to the sixth cycles: 200 mg·m-2·d-1 for 5 days. The clinical symptom remission rate after the treatment of CyberKnife in one week, the effective rate after CyberKnife in 3 months, the median intracranial progression-free survival time, overall survival, and the incidences of adverse reaction were comparatively analyzed. Results The clinical symptom remission rates of CyberKnife+TMZ group and CyberKnife group after the treatment of CyberKnife in one week were 93.6 % (29/31) and 96.8 % (30/31). There was no significant difference in the clinical symptom remission rates (χ2= 1.207, P=0.547). The effective rates of the two groups after CyberKnife in 3 months were 93.6 % (29/31) and 90.3 %(28/31). There was no significant difference in the effective rates (χ2 = 0.695, P= 0.706). The median intracranial progression-free survival time in CyberKnife + TMZ group (14.0 months) was significantly higher than that in the CyberKnife group (9 months) (χ2=8.977, P=0.003), and the median overall survival time in CyberKnife + TMZ group (15.0 months) was also significantly higher than that in the CyberKnife group (12.0 months) (χ2 = 5.190, P= 0.023). There was no significant difference in the adverse reaction of the central nervous system between the two groups (χ2=0.746, P=0.689), but the adverse reactions of the digestive system (χ2 = 6.062, P= 0.014) and the hematologic system (χ2 = 6.613, P= 0.010) in CyberKnife + TMZ group were significantly higher than those in the CyberKnife group. Systemic adverse reactions of the two groups were tolerated by most patients. Conclusions CyberKnife combined with TMZ is a feasible therapeutic option for NSCLC patients with brain metastases. This therapy can improve the median survival time to cerebral progression of the disease and the median overall survival time.

ABSTRACT

Neuroendocrine tumor of the pancreas (pNET) is a rare group of neoplasms with widely heterogeneity. Complete surgical resection remains the only potentially curative treatment for pNET. Compared to open surgery, minimal invasive approach treating pNET could decrease bleeding and shorten postoperative hospital stay, while didn′t show difference in operation time, postoperative complication rate and overall mortality. Therapeutic strategy was formulated by synthesizing clinical symptoms, tumor size and tumor stage. Minimal invasive approach can achieve radical curve of oncology and provide refine manipulation condition to improve surgical safety and efficacy, meanwhile realize function preservation. Minimal invasive approach is a safe and efficient method in treating pNET, but further prospective, randomized control trials are required.

ABSTRACT

Objective@#To summarize the incidence and characteristics of postoperative complications after laparoscopic pancreaticoduodenectomy(LPD), and to share our experience on management of complications.@*Methods@#The clinical data of 320 LPD performed by a single team in Sir Run Run Shaw Hospital and Zhejiang Provincial People′s Hospital between September 2012 and September 2017 were retrospectively analyzed, among which there were 196 males and 124 females with age of (60.2±11.6) years old.There were 306 patients who underwent standard LPD, and 14 patients who underwent extended LPD. The patients were divided into 2 groups of former 160 LPD and later 160 LPD according to the time order. By analyzing the differences of clinical outcomes between the two groups, especially focusing on the incidence of postoperative complications.The experience on management of complications was concluded. The prior surgical history of latter group was significantly higher than the former group(30.0%(48/160)vs. 18.8%(30/160), χ2=5.49, P=0.019), and the rest of baseline characteristics remained the comparable (P>0.05). For resectable lesions, LPD was performed by "No back" approach, following the principle of "From distal to cephalad, from ventral to dorsal, and from left to right" . As for the borderline resectable patients, LPD was performed by "Easy first" strategy. Student t test, χ2 test or Fisher test was used to analyzed the data between the two groups respectively.@*Results@#Of 320 LPD patients, 306 cases underwent standard LPD, 14 cases underwent LPD with resection of other organs.There were 278 LPD cases who followed "No back" approach, and 42 cases who followed "Easy first" strategy because of difficulty in creating the retro-pancreatic tunnel. And the overall morbidity was 32.2%(103/320) with reoperation rate of 5.3%(17/320). The perioperative mortality was 0.6%(2/320). The operation time of latter group was ((346.6±48.8)minutes), which was shorter than that of former group((358.0±54.4)minutes)(t=1.97, P=0.048). The blood loss of former and latter group remained comparable((207.9±135.8)ml vs.(189.6±121.4)ml, P=0.205). However, in subgroup analysis, the patients with blood loss less <200 ml of latter group decreased significantly from 59.4%(95/160) to 47.5%(76/160)(χ2=4.53, P=0.033). The overall morbidity of latter group was 28.8%(46/160), indicated a decrease from 35.6%(57/160) of former group without significant difference(P=0.188). Moreover, Grade A/B/C pancreatic fistula rate, Grade A/C bile leakage rate, Grade B/C postoperative hemorrhage rate of the later group tended to decrease, although they also didn′t reach a significant difference. However, the abdominal infection rate decreased significantly(χ2=3.93, P=0.047). The length of hospital stay remained comparable(P=0.156).@*Conclusions@#The most common complications after LPD were postoperative hemorrhage and pancreatic fistula. With specialized team and accumulated experience, the morbidity can decrease progressively by analyzing the leading cause and improving the technical skills.

ABSTRACT

Objective To investigate the expression of bone sialoprotein (BSP) in prostate cancer and its clinical significance. Methods Prostate cancer tissues of different pathological grades (68 cases) and benign prostatic hyperplasia tissues (22 cases) were selected. SP method was used to detect the expression of BSP. Serum total prostate-specific antigen (tPSA) levels of prostate cancer were detected by electrochemiluminescence immunoassay before the operation. Results Compared with no or low expression in the adjacent normal glandular tissues, the detectable levels of BSP were examined in most of the prostate cancer tissues. The expression rate of BSP in prostate cancer tissues was higher than that in benign prostatic hyperplasia tissues [76.47%(52/68) vs 13.64%(3/22),χ2=27.614, P<0.001]. The expression rates of BSP in well differentiated, moderately differentiated and poorly differentiated tissues according to cell differentiating degree (Gleason system) were 75.0 % (12/16), 77.5 % (31/40) and 75.0 % (9/12) respectively. There was no significant difference in various pathological grading (χ2=0.057, P=0.972). The expression rates of BSP in pathological stage pT2, pT3 and pT4 tissues were 62.16%(23/37), 95.24%(20/21) and 90.0%(9/10) respectively. A statistically significant association was found between BSP expression and pathological stage (χ2=9.338, P=0.009). Serum tPSA level of prostate cancer group with BSP expression was higher than that with no BSP expression [(69.06±25.52)μg/L vs (38.00±21.64)μg/L, F=19.355, P<0.001]. Conclusion The high expression of BSP in prostate cancer has a relationship with pathological stage and serum tPSA level, it may play an important role in the biological behaviour of prostate cancer.

ABSTRACT

Objective To compare the efficacies of intralesional hyaluronidase(HAase), intralesional dexamethasone(DEX), and intralesional HAase plus intralesional DEX on skin damage caused by vinorelbine extravasation in a rat model. Methods After establishing an animal model with vinorelbine extravasation in each lower extremity of 40 Sprague-Dawley rats, we treated the rats with intralesional HAase,intralesional DEX, intralesional HAase plus intralesional DEX,intralesional saline,or received no treatment as control.The wound area on 1 d, 4 d, 8 d, 12 d, 18 d, 24 d, 30 d and the time of healing were observed and compared.Results The wound area on 1 d, 4 d, 8 d, 12 d, 18 d and 24 d was significantly lower in intralesional HAase group, intralesional DEX group,intralesional HAase plus intralesional DEX group,and intralesional saline group than that in control group (P <0.05), and that was significantly lower in intralesional HAase group and intralesional HAase plus intralesional DEX group than that in intralesional DEX group and intralesional saline group (P <0.05). The healing time was significantly shorter in 4 therapy groups than that in control group [(25.1±3.1) d, (27.9±2.8) d, (23.0±3.2) d, and (28.4±3.9) d vs.(31.2±3.0) d, P <0.05], and that was significantly lower in intralesional HAase group and intralesional HAase plus intralesional DEX group than that in intralesional DEX group and intralesional saline group (P <0.05). Conclusion The monotherapy with intralesional HAase or intralesional DEX, with decreasing the extent of skin damage and shortening the healing time, is effective therapy for skin damage caused by vinorelbine extravasation, and the monotherapy with intralesional Haase is more efficacious. The efficacy of intralesional HAase plus intralesional DEX seems better than that of monotherapy.
