Application of indocyanine green in sentinel lymph node biopsy for breast cancer / 局解手术学杂志

Objective To explore the application value of indocyanine green (ICG)in sentinel lymph node biopsy(SLNB)for breast cancer.Methods A total of 160 patients with breast cancer in our hospital from January 2013 to December 2015 were analyzed,who were randomly divided into methylene blue group(n =65)and methylene blue plus ICG group(n =95).The success rate of detection,accuracy and false negative rate between two groups were compared.Results The success rate of detection and accuracy in methylene blue plus ICG group was significantly higher than thoase in methylene blue group,with statistically significant difference(P <0.05).The false negative rate of methylene blue plus ICG group was significantly lower than that of methylene blue group,with statistically significant difference (P <0.05).The number of sentinel lymph node in methylene blue plus ICG group was (2.9 ±0.9)/case which was more than (1.9 ± 0.5)/case in methylene blue group ,with statistically significant difference(P <0.05).The length of opertion of methylene blue plus ICG group was obviously shorter than that of methylene blue group.Conclusion Indocyanine green used in the sentinel lymph node detection for breast cancer can provide a reliable basis and reduce the false negative rate,who improves the level of diagnosis of breast cancer.

Protection of recurrent laryngeal nerve during thyroidectomy / 中华普通外科杂志

ObjectiveTo evaluate the effectiveness of surgical technique improvement in thyroid lobectomy for prevention of recurrent laryngeal nerve (RLN) injury. MethodsThe clinical data of 85 patients of thyroid disease undergoing 126 lobectomies from Jan 2010 to Jan 2011 were retrospectively analyzed.All patients undergone accurate thyroid lobectomy with accurate envelop anatomic dissection,skeletonized blood vessels. Recurrent laryngeal nerve was all dearly exposed.ResultsNo-bleeding surgical area was achieved.The RLN was exposed.Unilateral temporary RLN injury occurred in 2 cases.The rate of RLN injury was 1.59％(2/126). There was no bilateral and perpetual RLN injury.ConclusionsCarrying through the accurate thyroid lobectomy,the incidence of RLN injury is low.

Results of induction chemotherapy followed by concurrent chemoradiation in unresectable locally advanced non-small lung cancer / 中华放射肿瘤学杂志

Objective To study the toxicity and efficacy of induction chemotherapy followed by concurrent cisplatin chemotherapy and three dimensional conformal radiotherapy (3DCRT) for inoperable locally advanced non-small cell lung cancer (LA-NSCLC). Methods Totally 76 patients with LA-NSCLC received two cycles induction chemotherapy followed by 3DCRT with a median dose of 68 Gy (64 to 74 Gy).During the 3DCRT, cisplatin (25 mg/m2, weekly) was given intravenously for 6-7 times. Results The CR rate, PR rate and overall response rate of induction chemotherapy were 3% ,42% and 45%. After the concurrent chemoradiation, the corresponding figures were 10%, 62% and 72%. The median survival time (MST) and median progression-free survival (PFS) of all patients were 16.6 months and 10.3 months. The 1-, 2- and 3-year overall survival (OS) and PFS rates were 67% , 35% , 21% and 42% , 15%, 6%. Of patients with stage ⅢA and stage ⅢB disease,the MST were 19.7 months and 15.6 months, the PFS were 10.8 months and 9.4 months. The major treatment-related toxicities included radiation esophagitis, radiation pneumonitis, nausea ( or vomiting) and leukopenia. The major pattern of treatment failure was distant metastasis. Forty-five patients (59%) experienced the local recurrence or/and distant metastasis, including 4 (9%) with in-field failure, 38 (84%) distant metastasis and 3 (7%) malignant pleural effusion. Conclusions Induction chemotherapy followed by concurrent weekly cisplatin and 3DCRT for inoperable locally advanced NSCLC results in encouraging outcomes and acceptable tolerance.
