  • Clinical Significance of Internal Mammary Nodes in Diagnosis and Treatment of Breast Cancer

    Objective To explore the clinical significance of internal mammary nodes in diagnosis and treatment of breast cancer. Methods The research papers on internal mammary nodes at home and abroad were analyzed in order to summarize the distribution, metastasis, detection and the effects of clinical treatment of the internal mammary nodes in breast cancer. Results The internal mammary nodes mainly locate near the sternum, along with the internal mammary artery and vein in the thorax. They were prone to metastasize at early stage and the metastasis rate also increased with the increased number of axillary lymph nodes in breast cancer. It could influence the recovery of the breast cancer patients by taking biopsy and treatment to the internal mammary nodes. Conclusion The biopsy and treatment of internal mammary nodes are useful for the patients with breast cancer to avoid the recurrence and helpful to stage, treatment and prognosis judgement of the breast cancer patients.

  • Research on Cluster Management in Nutritional Intervention for Nasopharynx Cancer Patients Undergoing Intensity Modulated Radiation Therapy

    ObjectiveTo research on the influence of cluster management on the nutritional intervention for nasopharynx cancer patients undergoing intensity modulated radiation therapy (IMRT), in order to discuss effective and feasible nutrition management method. MethodEighty-three nasopharynx cancer patients undergoing IMRT between June 2013 and December 2014 were selected as the study subjects. They were divided into two groups randomly. Regular health education and nutritional guidance were carried out for the 41 patients in the control group, while nutritional risk screening (NRS)-2002 nutrition screening, nutrition assessment and nutritional intervention were carried out for the 42 patients in the intervention group. Nutrition risk, nutritional status and side-reaction were recorded and evaluated for both groups of patients. ResultsAfter treatment, NRS-2002 score of the intervention group was lower than the control group (P<0.05). Body weight, constitutional index, skinfold thickness of triceps brachii muscle, mid-arm circumference and mid-arm muscle circumference of the intervention group were better than the control group (P<0.05). Total serum protein, serum albumin, serum transferrin were better and the rate of levelⅢ-Ⅳ radiation-induced oral mucositis was lower in the intervention group than that in the control group (P<0.05). ConclusionsThe application of cluster management model in nutritional intervention is a way to promote patients' rehabilitation, which can effectively improve the whole body situation of nasopharynx cancer patients, and reduce malnutrition rate and side-reaction.

  • Risk Factors Affecting The Contralateral Breast Cancer after Treatment of Primary Breast Cancer

    Objective To study the risk factors for contralateral breast cancer (CBC) in women after regular treatment of the primary breast cancer. Methods Between January 1997 to December 2002, the clinical data of 340 breast cancer patients at our institution were retrospectively analyzed. In all the patients a detailed analysis was carried out with respect to age, operation type, radiation therapy technique and dose, the use of chemotherapy or hormone therapy, and other clinicopathologic characteristics. The KaplanMeier method was used to estimate the actuarial rate of CBC. The Cox proportional hazard regression model was used to estimate the relative risk factors of CBC. Results Fourteen cases were diagnosed to be CBC, thus overall incidence of CBC was 4.1%. Ten-year CBC incidence (2.7%) was higher than 5-year incidence of CBC (1.4%). Univariate analysis showed that the risk factors of CBC at 5-year and 10-year included: ≤45 years old, medullary carcinoma, family history of breast cancer and being taken without endocrine therapy (P<0.05), while chemotherapy and radiotherapy were not risk factors of CBC (P>0.05). Mutivariate analysis showed that ≤ 45 years old and being internal breast radiotherapy were independent risk factors of CBC at 5-year and 10-year (P<0.05). Conclusions CBC may occur in these primary breast cancer patients with age ≤45 years old, medullary carcinoma, family history of breast cancer. In order to reduce the incidence of CBC, endocrine therapy rather than internal breast radiotherapy should be performed in early breast cancer patients.

  • Research progress on the identification of central lung cancer and atelectasis using multimodal imaging

    Central lung cancer is a common disease in clinic which usually occurs above the segmental bronchus. It is commonly accompanied by bronchial stenosis or obstruction, which can easily lead to atelectasis. Accurately distinguishing lung cancer from atelectasis is important for tumor staging, delineating the radiotherapy target area, and evaluating treatment efficacy. This article reviews domestic and foreign literatures on how to define the boundary between central lung cancer and atelectasis based on multimodal images, aiming to summarize the experiences and propose the prospects.

  • Radiotherapy for refractory choroidal hemangioma

    ObjectiveTo observe the effectiveness of radiotherapy for refractory choroidal hemangioma. MethodsEight patients (8 eyes) with choroidal hemangioma were enrolled in this retrospective study. All the patients had received laser or photodynamic therapy before without effectiveness. The patients included 7 males and 1 females. The age was ranged from 11 to 54 years old, with an average of (27.50±15.18) years. All the patients were affected unilaterally, including 3 right eyes and 5 left eyes. There were 5 eyes with circumscribed choroidal hemangioma, 3 eyes with diffused choroidal hemangioma. All eyes had extensively exudative retinal detachment. The vision was from light sensation to 0.01. The volume of the tumors was ranged from 1.96 to 5.35 cm3, with a mean of (3.37±1.06) cm3. All the patients were treated with X rays by conventional fractional radiotherapy. Four of 8 patients were applied 24Gy totally in 8 fractions, while the other 4 patients were applied 46Gy in 23 fractions. Follow-up period ranged from 7 to 95 months, with medium of 42 months. ResultsRetinas reattached in all the eyes while exudation being absorbed. No retinal detachment happened again. To the last follow-up, the vision was from light sensation to 0.6. Visual activity improved in 6 eyes while 2 eyes improved obviously. Visual acuity was stable in remaining 2 eyes. The volume of the tumors decreased to 1.24-2.16 cm3, with a mean of (1.68±0.30) cm3. The percentage of the tumor decreased by 14.6-72.7, with an average of (44.89±21.30)%. No radiotherapy-associated complication occurred.

  • Progress in Diagnosis and Treatment of Double Primary Lung Cancer

    With the continuous development of living standards, medical imageology, pathology and the technique of cell biology, the morbidity of double primary lung cancer (DPLC) grows rapidly in recent years. The thoracic surgeons have constantly improved its standard of diagnosis and treatment. At the present, union diagnosis of multiple indexes, defining clinical stage based on a single leision, and the early surgery have been accepted by most of the thoracic surgeons. The video-assisted thoracoscopic surgery (VATS), for its advantage of small trauma, has been accepted by thoracic surgeons and been widely used now. It's a promising treatment for DPLC and other chest diseases. In addition, it has been proved that there was no statistical diffence in prognosis between the simple radiotherapy and surgical treatment. The traditional concept of thoracic surgery is facing severe challenges. Therefore, we review the clinical diagnosis and treatment progress of DPLC as follows.

  • Progress on Diagnosis and Treatment of Abdominal Aggressive Fibromatosis

    Objective To comprehend the concept, pathology, molecular mechanisms, diagnosis, and treatmentof aggressive fibromatosis (AF), and to find a novel way to cure aggressive fibromatosis. Method The literatures about the definition, molecular mechanisms, and clinical research of AF were reviewed and analized. Results AF is rare and benign fibromatous lesion that is the result of abnormal proliferation of myofibroblasts. The pathologic features of AF isa benign disease, but it has “malignant” biological behavior. The tumor often involved the surrounding organs and bloodvessels, and caused death of patients. For patients with clinical symptoms or complications, complete excision of thetumor is the treatment of choice. Even if the operation to ensure the negative margin also has a higher recurrence rate, soits treatment requires multidisciplinary treatment. Conclusions The mechanism of AF is very complex, and it’s mecha-nism is still unclear. Clinical management of patients with AF is difficult and controversial, at present, the most effective treatment for AF is operation resection. The effects of adjuvant radiotherapy, chemotherapy, and other treatment after operation for AF still need further study.
