OBJECTIVETo investigate the psychological impact of mastectomy on women with breast cancer.

METHODSQuestionnaires were answered by 90 patients after mastectomy for breast cancer. The data were collected and analyzed regarding the age, occupation, education, income and living place of the patients. Their psychological changes were compared and evaluated statistically using chi-square analysis.

RESULTSMastectomy caused psychological impact on half of the patients, which included fear of cancer, feeling of body incompleteness, inconvenience in working and social communication, less sexual act and low spirit. 79 percent of the patients considered breast reconstruction unnecessary. 54 percent did not know that the breast could be reconstructed. The patient feelings differed with the age, occupation, income and living place.

CONCLUSIONMastectomy hurts patient psychological health.

BACKGROUND AND OBJECTIVEAt present, although appropriate radiotherapy and combined treatments are widely used for the patients with primary nasopharyngeal carcinoma (NPC), local or regional recurrence rates are still high. According to clinical performance, pathology, and diagnostic imaging of the patients with the first recurrence of NPC, this study analyzed the clinical features of recurrent NPC to provide a reference for tracking the rules of recurrence after the treatment of patients with NPC.

METHODSClinical data of 337 patients diagnosed with recurrent NPC for the first time were collected. The diagnoses were based on pathology and/or imaging and the patients were treated at the Sun Yat-sen University Cancer Center between January 1999 and December 2004. Data used for statistical analysis included clinical performance during the patient visit, the extension of the invasion as shown on imaging, pathologic features, Epstein-Barr virus (EBV) serology, restaging, etc.

RESULTSPatients were staged according to the system developed by the International Union Against Cancer (UICC) and the American Joint Committee on Cancer (AJCC) in 2002. Patients with diseases at stages I/II accounted for 25.2%, while those with stage III/IV accounted for 74.8%. The median interval of relapse was 25 months. Patients had local recurrence (69.4%), regional recurrence (4.5%), or both (26.1%). Epistaxis and headache were the most common symptoms. Abduct dysfunction and facial numbness induced by cranial nerve damage were the most common signs. The probability of invasion of structures adjacent to the nasopharynx, such as the oropharynx, the prestyloid space, and the carotid sheath area, was low in patients with recurrent NPC. By contrast, the probability of invasion of structures far from the nasopharynx, such as the base of the skull, the paranasal sinuses, cranial nerves, the cavernous sinus, the brain, the pterygopalatine fossa, the infratemporal fossa, the orbital apex, and the soft palate, was higher in recurrent NPC.

CONCLUSIONSThe most common interval of relapse is about 2 years. The relapsed disease is usually more widespread and located deeper. Most recurrent NPC is advanced disease.

OBJECTIVETo study the role of cerebrovascular hemodynamic indexes (CVHI) changing in stroke and to provide reference for stroke prevention and risk factor study.

METHODSFrom 2003 to 2004, participants aged 40 years and above in two communities in Fengxian district were recruited by cluster sampling. Risk factors of stroke and CVHI were investigated and checked during baseline investigation. A total of 10 565 individuals completed the survey and met the inclusion criterion. After baseline investigation, the cohort was followed up for stroke occurrence. Relative risk (RR) of CVHI and common risk factors were estimated by cohort study design.

RESULTSAge of the cohort was (56.2 ± 11.4) years. 4444 (42.1%) were males and 6121 (57.9%) were females. Total follow-up duration was 67 885.7 person-years. A total of 195 stroke cases occurred and incidence density of stroke was 287.2 per 100 000 person-years. Stroke incidence in exposure groups of hypertension, heart disease and alcohol drinking was 3.47% (108/3118), 2.96% (21/710) and 2.50% (47/1882), respectively. The incidence in corresponding non-exposure group was 1.17% (87/7448), 1.77% (174/9855) and 1.70% (148/8683) respectively. There was significant difference between 2 groups (χ(2) value was 62.72, 4.56 and 4.94, respectively, P < 0.05). Stroke incidence in CVHI score < 25, 25 - 49, 50 - 74 and ≥ 75 groups was 9.12% (59/647), 5.68% (44/775), 2.52% (39/1545) and 0.72% (53/7403)(χ(2)trend = 273.57, P < 0.05), respectively. Incidence of stroke in 40 - 49, 50 - 59, 60 - 69, ≥ 70 years age group was 0.22% (8/3565), 1.28% (43/3357), 2.71% (50/1848) and 5.88% (94/1600) (χ(2)trend = 181.48, P < 0.05), respectively. Multiple Cox regression analysis indicated that RR (95%CI) value of hypertension and cigarette smoking was 1.40(1.02 - 1.92) and 1.59(1.19 - 2.12), respectively when comparing with non-exposure group. RR (95%CI) value in CVHI score < 25, 25 - 49 and 50 - 74 points group were 6.15 (4.08 - 9.26), 4.55 (2.98 - 6.96) and 2.68 (1.75 - 4.09), respectively when comparing with the score ≥ 75 points group. RR (95%CI) value in age 50 - 59, 60 - 69 and ≥ 70 years group was 4.61 (2.16 - 9.82), 7.81 (3.67 - 16.60) and 13.49(6.44 - 28.24), respectively when comparing with below 40 years group.

CONCLUSIONCVHI score is the strong independent predictive factor and hypertension, cigarette smoking and age are the independent risk factors of stroke.

OBJECTIVETo compare the hemostatic effect between absorbable hemostatic fluid gelatin (HFG) and absorbable gelatin sponge(GS) during operation of unilateral open-door cervical expansive laminoplasty.

METHODSThe clinical data of 83 patients underwent unilateral open-door cervical expansive laminoplasty from February 2014 to May 2016 were retrospectively analyzed. According to the used hemostatic materials, patients were divided into two groups. In HFG group, there were 30 males and 11 females, ranging in age from 29 to 81 years, with an average of(55.6±11.6)years; 14 cases were simple cervical spinal stenosis, 9 were cervical spinal stenosis and ossification of posterior longitudinal ligament, and 18 were cervical spinal stenosis complicated with multiple cervical disc herniation. And in GS group, there were 32 males and 10 females, ranging in age from 36 to 78 years, with an average of (55.4±11.1) years; 12 cases were simple cervical spinal stenosis, 10 were cervical spinal stenosis complicated with ossification of posterior longitudinal ligament, and 20 were cervical spinal stenosis complicated with multiple cervical disc herniation. There was no significant difference in the age, gender, and disease categories of patients between two groups (>0.05). The operative time, intraoperative bleeding, postoperative drainage, and postoperative complications were compared between two groups.

RESULTSThe average operative time, intraoperative bleeding, and postoperative drainage in HFG group were(137.2±30.0) min, (156.1±74.6) ml, and (212.1±67.6) ml, respectively; and in GS group were (154.8±33.5) min, (242.9±120.7) ml, and(303.3±115.5) ml, respectively. There were significantly differences in above items between two groups(<0.05). No acute heamatoma or related complications was found postoperatively.

CONCLUSIONSCompared with GS, HFG can obviously decrease operative time, intraoperative bleeding, and postoperative drainage. It is a safe and effective hemostatic material for the operation of unilateral open-door cervical expansive laminoplasty.

Although many studies have investigated intensity-modulated radiation therapy (IMRT) for nasopharyngeal carcinoma (NPC), sample sizes in the reported studies are usually small and different in outcomes in different T and N subgroups are seldom analyzed. Herein, we evaluated the outcomes of NPC patients treated with IMRT and further explored treatment strategy to improve such outcome. We collected clinical data of 865 NPC patients treated with IMRT alone or in combination with chemotherapy, and classified all cases into the following prognostic categories according to different TNM stages: early stage group (T1-2N0-1M0), advanced local disease group (T3-4N0-1M0), advanced nodal disease group (T1-2N2-3M0), and advanced locoregional disease group (T3-4N2-3M0). The 5-year overall survival (OS), local relapse-free survival (LRFS), and distant metastases-free survival (DMFS) were 83.0%, 90.4%, and 84.0%, respectively. The early disease group had the lowest treatment failure rate, with a 5-year OS of 95.6%. The advanced local disease group and advanced nodal disease group had similar failure pattern and treatment outcomes as well as similar hazard ratios for death (4.230 and 4.625, respectively). The advanced locoregional disease group had the highest incidence of relapse and death, with a 5-year DMFS and OS of 62.3% and 62.2%, respectively, and a hazard ratio for death of 10.402. Comparing with IMRT alone, IMRT in combination with chemotherapy provided no significant benefit to locoregionally advanced NPC. Our results suggest that the decision of treatment strategy for NPC patients should consider combinations of T and N stages, and that IMRT alone for early stage NPC patients can produce satisfactory results. However, for advanced local, nodal, and locoregional disease groups, a combination of chemotherapy and radiotherapy is recommended.

OBJECTIVETo analyze the full nucleotide sequence of a null allele of major histocompatibility complex class I chain-related gene (MICA).

METHODSA sequence-based typing method was used to determine the nucleotide sequence of the MICA gene. Potential alleles were identified with a computer program.

RESULTSThe identified allele has possessed a sequence similar to that of MICA*027 except for a C→T substitution at position 184 in codon 62 (CAG→TAG) of exon 2. As a stop codon, this may result in a truncated protein.

CONCLUSIONA null allele of MICA gene has been identified. The sequence has been submitted to the Genbank nucleotide sequence database (submission No. HWS10011131), which was officially named as MICA*063N by the WHO Nomenclature Committee in October 2010.
