Each woman of childbearing age has the right to enjoy reproduction, including cancer patients. Breast cancer is the most common malignant tumor in women. Many factors led to the significant increase of young patients with fertility problems, and the majority of doctors neglected their reproductive requirements in clinical work. Given the comprehensive treatment, almost every young patient suffers from fertility decline and even loss. Patients who chose to get pregnant also harbor a variety of concerns. This paper reviews the effects of comprehensive treatment on fertility, preservation strategies, pregnancy and prognosis, optimal time for pregnancy, and other aspects and provides guidance for young breast cancer patients in their reproduction choices.

Objective To evaluate the effectiveness of tobacco control interventions among employees in centers for disease control and prevention (CDC) in Hebei Province. Methods Tobacoo control interventions, including health education, Quit and Win competition, and founding smokeless CDC, were carried out in CDC system in Hebei Province from May 2006 to June 2008. Surveys on smoking rate of employees and on average cigarette quantity consumed by male employee smokers were conducted at the beginning and the end of the interventions. Results In 2006, 9 931 employees in 174 centers at provincial, city, county level in Hebei Province participated in this study. The overall smoking rate was 25.69%. Male employees had a higher smoking rate (51.28%) than the females (0.68%). The smoking rate of male employees was 50.92%, 49.48% and 51.72% for provincial, city and county CDC levels, respectively. The average cigarettes consumed by one smoker in one day were 15.0. In 2008, 9 139 employees in 189 centers participated in this study. The overall current smoking rate was 25.07%. The smoking rate was 52.26% and 0.43% for males and females, respectively. The smoking rates of male employees in provincial and city CDCs were 43.93% and 46.18%, significantly lower than those in 2006. The smoking rate of male employees in county CDCs was 53.98%, much higher than that in 2006. The average cigarettes consumed by one smoker in one day in 2008 were 12.4, significantly less than that in 2006. The current smoking rate of male employees in smokeless CDCs was 48.0% , significantly lower than 56.9% in non smokeless CDCs. Conclusion Male employees in Hebei Province CDC system had a high smoking rate. Tobacco control interventions play a role in reducing smoking rate and cigarettes consumption.

Objective To summarize the clinical characters,diagnosis and surgical treatment of primary hyperparathyoidism (PHPT).Methods The diagnosis,treatment and efficacy of 35 cases of PHPT were retrospectively reviewed.Results PHPT presented a variety of clinical manifestations,and occoured to different age groups without significant gender differences.All the 35 cases had elevated blood calcium and PTH.All patients underwent preoperative ultrasonography and 99Tcm-MIB imaging,and the positive rates were 68.6％ and 97.1％ respectively.34 patients received surgical treatment,among whom 30 cases had parathyroid adenoma,1 case had parathyroid hyperplasia and 3 cases had parathyroid carcinoma.Through operation,31 cases were cured,2 cases improved,and 1 case of parathyroid carcinoma suffered from lung metastasls.Conclusions PHPT can be diagnosed according to co-elevated serum calcium and PTH.Ultrasonography combined with 99Tcm-MIB imaging should be recommend for preoperative localization.The main cause of PHPT is solitary parathyroid adenoma.PTPT can be cured by surgery.Minimally invasive parathyroidectomy with accurate location is an efficient surgical strategy,and the prognosis is favorable.

Objective:To analyze the factors related to metastasis of contralateral central lymph node (CLN) in cN0 papillary thyroid car-cinoma (PTC) and discuss the indications for CLN dissection. Methods:We enrolled 149 unilateral PTC patients who underwent total thyroidectomy and prophylactic bilateral (CLN) dissection. This work analyzed the relationship of gender, age, extrathyroidal extension, multifocality, thyroiditis, ipsilateral central lymph nodes, and prelaryngeal lymph node with CLNs. Results:The rates of metastasis to ip-silateral and contralateral central compartments were 73.2%and 23.5%, respectively. In univariate analysis, gender, age, tumor size, multifocality, and thyroiditis were not important in predicting contralateral central compartment lymph node metastasis (P=0.792, 0.097, 0.531, 0.269, and 1.000, respectively);by contrast, extrathyroidal extension (P=0.017), prelaryngeal lymph nodes (P=0.006), and ipsilateral CLNs (P<0.001) are related to CLN metastasis. However, multivariate analysis showed that ipsilateral central metastasis was an independent risk factor for lymph node metastasis in the contralateral central region when the number of ipsilateral central metas-tases is≥3 (P=0.010). Conclusion:Extracapsular invasion, prelaryngeal lymph nodes, and ipsilateral CLN influence the metastases of CLN. Bilateral CLN dissection should be performed when the number of ipsilateral central metastases is≥3 and there is merger of ex-tra-laryngeal lymph nodes or capsule invasion.

OBJECTIVE To study the methods and curative effects of reconstruction of oropharyngeal defects after resection of tonsillar cancer. METHODS Nineteen patients with tonsillar cancer underwent operation. The choice of surgical procedure was decided on the size of the lesions. The tumor was resected through the hyoid approach and mandibular swing approach. Surgical defects were repaired immediately with tongue flap, temporalis myofascial flap, pectoralis major myocutaneous flap. RESULTS The functions of respiration, chewing, deglutition, and speech were restored satisfied in all patients. Partial necrosis of the pectoralis major myocutaneous flap occurred in one patient, and mild difficulty of open mouth in 3 patients after repaired with temporalis myofascial flap. CONCLUSION Choosing what is optimum from multiple feasible surgical methods is prerequisite for better oropharyngeal function and quality of life in patients with tonsillar cancer.

Objective To investigate the relationship between subgroups of central lymph node metastasis (sCLNM) and lateral lymph node metastasis (LNM) of unilatal papillary thyroid carcinoma (uPTC) with cervical lymph node negative(cN0).Methods The clinical and pathological data of 161 patients with cN0-uPTC who underwent total thyroidectomy+central lymph node dissection+lateral lymph node dissection from Jan.2016 to Dec.2016 were retrospectively analyzed.The relationship between the lymph node metastasis of each subarea in the central area of the affected side and the lymph node metastasis of the affected side was investigated.Results Binary logistic regression analysis of cN0-uPTC subregions in the affected central region showed:pre-laryngeal lymph node metastasis,pre-tracheal lymph node metastasis and paratracheal lymph node metastasis were independent risk factors for lymph node metastasis in the affected lateral region(P=0.008,0.016,0.035,respectively).Prelaryngeal lymph node metastasis was an independent risk factor for lymph node metastasis in the affected area Ⅱ (P=0.015).Pre-tracheal lymph node metastasis was an independent risk factor for lymph node metastasis in affected area Ⅲ (P=0.004).Pre-tracheal and para-tracheal lymph node metastasis were independent risk factors for lymph node metastasis in the affected Ⅳ area (P=0.035,0.011,respectively).Conclusions The lymph node metastasis pathway of thyroid cancer had certain regularity.The pre-laryngeal lymph node metastasis has the prediction value for the lymph node metastasis of the affected area Ⅱ.The pre-tracheal lymph node metastasis has the prediction value for the lymph node metastasis of the affected area Ⅲ.The pre-tracheal and paratracheal lymph node metastasis have the prediction value for lymph node metastasis of the affected area Ⅳ.Lymph node dissection in affected areas Ⅲ and Ⅳ needs to be considered in patients with pre-tracheal or paratracheal lymph node metastases.On this basis,lymph node dissection on the affected areas Ⅱ,Ⅲ,and Ⅳ might be considered if there is pre-laryngeal lymph node metastasis at the same time.

OBJECTIVE: To analyze the mutation and abnormal expression of the FHIT gene in human hypopharyngeal carcinoma. METHOD: Matched normal and cancerous tissues from 24 patients with hypopharyngeal squamous cell carcinoma were obtained immediately after surgery. Total RNA was extracted, the FHIT gene was detected by nested RT-PCR and DNA sequencing technology. RESULT: Normal sized FHIT transcript was detected in 23 of the 24 cases of normal matched tissues. Aberrant FHIT transcripts were found in 9/24 (37.5%) cases in hypopharyngeal carcinoma. Aberrant FHIT transcripts rate of well-differentiated, moderately differentiated and poorly differentiated squamous cell carcinoma, was 28.6% (2/7), 50.0% (4/8) and 33.3% (3/9), respectively. There the carcinoma with FHIT aberrant transcripts was neither corresponding to histological grade (P>0.05) nor to lymphatic metastasis. The sequence analyses of the two aberrant cDNAs revealed absence of exon 8 and exon 7-9. All initial deletion were in conjunction of exons. CONCLUSION High deletion rate of the FHIT gene in Chinese hypopharyngeal squamous cell carcinoma suggested the FHIT gene, a candidate tumor suppressor gene at 3p14.2, plays an important role in the tumor carcinogenesis, development and progression of the tumor, and thus may become a new prognostic marker in hypopharyngeal carcinoma.
