  • Many types of cancer, current therapy other than surgery and/or radiotherapy was of only limited efficacy. At the basic chinese traditional medicine(TCM) there was increased understanding of the additional basic and clinical neoplasm treatment research. The metastasis and recurrence of neoplasm was the basis of yudu(餘毒) on remained neoplasm cell and stagnation of blood, thermotoxo, phlegm, asthenia of healthy enerngy, stagnation of vital energy. The principles therapy of neoplasm on metastasis and recurrence was based on knowledge of the method of support the healthy energy and strengthen the body resistance, promote blood circulation to remove blood stasis, clear away heat and toxic materials, dissipate phlegm and disperse the accumulation of evils, regulate vital energy and disperse the depressed vital energy. But the major clinical features of neoplasm was to be considered in developing a treatment plan include (1) distinguish between clinical and pathologic staging - acute and chronic, (2) classification of pathologic pattern, and (3) distinction of body situation : for examples asthenia - sthenia etc. It was most important to distinguish between supporting the healthy and eliminating the evil factors and to treat differently at the root and the branch cause of a neoplasm. This paper's results indicate that identification and effective use of TCM medicines inhibited netastasis and decreased recurrence and then we were able to expect increasing survival rate.

  • Objective : Recently, the survival rate and prognosis of spontaneous intracerebral hemorrhage[S-ICH] has improved, and their enhanced survival has become associated with a consequent rise in the recurrence of S-ICH. The aim of this study is to improve the prevention of recurrent S-ICH. Methods : Between January 1999 and March 2004, we experienced 48 cases of recurrence. We classified the patients into the two groups; a double ICH group and a triple ICH group. We investigated their brain CTs, MRIs, cerebral angiographies, and medical records, retrospectively. Results : Majority of patients had the intervals at least 12 months, and most of patients underwent conservative treatment. The most common hemorrhage pattern of recurrence was ganglionic-ganglionic [basal ganglia - basal ganglia], and the second attack was contralateral side of the first attack in a large percentage of all patients. Prognosis of patients was worsened in recurrent attack. Nearly all patients had medical history of hypertension, and most patients have taken antihypertensive medication at the arrival of emergency room. Conclusion : In treating hypertension for S-ICH patients, we stress that blood pressure must be thoroughly controlled over a long period of time.

  • 목 적 : 요로 감염은 진단 및 치료가 일찍 이루어지지 않으면 심한 신장 손상을 일으킬 수 있는 질환이고 재발 역시 잦은 질환이므로 미리 재발이 예방된다면 신장의 손상을 줄일 수 있을 것이다. 저자들은 요로 감염의 재발에 영향을 주는 위험인자를 분석하여 위험성이 높은 환아들을 조기에 선별하여 재발을 조기에 진단함으로 손상을 줄이는데 도움을 주고자 본 연구를 시행하였다. 방 법 : 2000년 1월부터 2001년 12월까지 고려대학교 구로병원 소아과에서 요로 감염으로 치료받은 환아 168명 중에 6개월 이상 추적 관찰한 93명을 대상으로 하였으며 의무 기록지를 바탕으로 후향적 조사를 하였다. 요로 감염의 재발을 진단하기 위해 매달 소변 배양 검사를 실시하였다. 결 과 : 총 재발률은 32.3%로 남아에서는 37.1%였고 여아에서는 17.4%였다(P<0.05). 요로 감염시의 원인균으로는 초발이나 재발에 모두 E.coli가 가장 많았다. 재발 감염이 있는 남아의 초발 감염은 재발이 없는 남아보다 발병 시기가 빨랐다($4.8{\pm}1.0$개월 대 $16.5{\pm}3.8$개월, P<0.05). 첫 감염 후 첫 6개월내에 약 77% 정도에서 재발을 하였는데 남아에서의 첫 감염 후 재발이 여아에서의 재발보다 빨랐다($3.7{\pm}0.6$개월 대 $14{\pm}8.2$개월, P<0.05). 1세 미만에 요로 감염이 발병한 환아에 있어 재발 횟수는 연간 $0.69{\pm}0.8$회로 1세 이상에서 요로 감염이 발병한 환아의 재발 횟수인 연간 $0.16{\pm}0.4$회보다 의의있게 높았으며 구조적인 이상 유무가 재발에 미치는 영향은 없었다. 결 론 : 요로 감염의 재발에 대한 위험인자로는 성별과 연령이 중요하게 생각되며 남아인 경우, 1세 미만인 경우가 이에 해당한다. 그러므로 특히 이런 환아들에서는 정기적으로 매달 소변 배양 검사를 감염 후 적어도 첫 6개월 꼭 시행하는 것이 바람직하다. 예방적 항생제 요법을 하는 경우에 방광 요관 역류는 재발의 위험인자로 생각되지는 않으며 따라서 방광 요관 역류가 있는 경우에는 예방적 항생제 요법을 시행하여야 할 것이다.

  • 배경: 본원에서 자발성 기흉으로 흉강경을 이용 폐 쐐기절제술 후 퇴원한 환자가운데 재발로 수술을 다시 받은 환자에서 기흉의 재발에 관한 위험 인자에 대해 연구하였다. 대상 및 방법: 2002년 1월부터 2005년 12월까지 본원 흉부외과에서 흉강경을 이용하여 흉막 유착술 없이 폐 쐐기절제술만을 시행한 235명을 대상으로 하였다. 퇴원 후 외래 추적관찰 중에 재발이 없었던 A군(225명: 96%), 재발이 있었던 B군(10명: 4%)으로 나누어서 후향적 조사를 통하여 재발 위험인자에 대하여 알고자 하였다. 결과: 각 군의 평균나이는 재발되는 군에서 $19.6{\pm}7.17$세로 더 어렸으며(p<0.05), 각군 남녀 비는 남자가 많았으나, 통계학적 의의는 없었다 흡연력, 병변 부위 및 폐허탈 정도는 양군사이에 유의한 차이는 없었다. 수술적 요인에 대한 것으로 술 후 공기 누출기간이 길수록, 흉관 거치 기간이 짧을수록 재발 가능성이 더 높았으며(p<0.05), 평균 재발기간은 $10.2{\pm}8.5$개월($0.6{\sim}22$개월)이었다. 재발된 군 중 4명은 술 후 한달 동안 충분한 준비 운동 없는 과격한 운동(농구 등)을 했던 경험이었다. 술 후 재발에 영향을 주는 단일 변수는 수술 시 나이,공기 누출기간, 키/몸무게 비 및 흉관 유지 기간이었으며, 다중 변수에 의한 위험 인자는 수술 시 나이, 신장/몸무게 비, 공기 누출 및 흉관 유지 기간 순이었다 결론: 자발성 기흉에서 흉강경을 이용한 폐기포 절제술은 재발율이 개흉술에 비하여 높지 않아서 시행할 수 있지만, 재발 위험인자로 나이가 젊거나, 큰 신장/몸무게비, 지속적인 공기 누출 있거나 짧은 흉관 유지 기간이었으며, 퇴원 후 너무나 빠른 심한 운동은 폐기포절제술 후 기흉 재발의 원인이 될 수 있다.

  • The aim of the present study was to determine whether allogeneic red blood cell transfusions showed a deleterious effect and what might be preoperative risk factors for blood transfusion in patients with TNM stage II colon cancer. Total 470 patients who fulfilled inclusion criteria were selected for a further 10-year follow-up study. We found that there were statistical significance between non-transfused and transfused group in mortality (P=0.018), local recurrence (P=0.000) and distant metastasis (P=0.040). Local recurrence and distant metastasis between 1 to 3 units and more than 3 units group did not show any significant differences. There was no difference in survival rate between non-transfused and 1 to 3 units group (log rank=0.031, P=0.860). The difference between different blood transfusion volume in transfused patients was found (78.77% vs 63.83%, P=0.006). Meanwhile, the significant difference of survival rate was existed between non-transfused group and more than 3 units group (84.83% vs 63.83%, P=0.002 ). Univariate analysis showed the following 3 variables to be associated with an increased risk of allogeneic blood transfusions: preoperative CEA level (P<0.05), location of tumor (P<0.01) and diameter of tumor (P<0.01). Multivariate analysis revealed that location of tumor and diameter of tumor are two independent factors for requirement of perioperative transfusions. Therefore, allogeneic transfusion increase the postoperative tumor mortality, local recurrence and distant metastasis in patients with stage II colon cancer. The postoperative tumor mortality, local recurrence and distant metastasis were not associated with the blood transfusion volume. The blood transfusion volume was associated with the survival rate. Location of tumor and diameter of tumor were the independent preoperative risk factors for blood transfusion.

  • Background: Short-course preoperative radiation (SCRT) with delayed surgery was found to increase pathologic complete response (pCR) rates in several trials. However, there was no clear answer on whether SCRT or long-course chemo-radiotherapy (LCRT) is more effective. Therefore we conducted this meta-analysis to evaluate the safety and efficacy of SCRT versus LCRT, both with delayed surgery, for treatment of rectal cancer. Materials and Methods: The literature was searched from PubMed, EMBASE, Web of Science, Cochrane Library and clinicaltrials.gov up to November, 2014. Quality of the randomized controlled trials (RCTs) was evaluated according to the Cochrane's risk of bias tool of RCT. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was used to rate the level of evidence. Review Manager 5.3 was employed for statistical analysis. Pooled risk ratios (RRs) and 95% confidence intervals (CIs) were calculated. Results: Three RCTs, with a total of 357 rectal cancer patients, were included in this systematic review. Metaanalysis results demonstrated there were no significantly differences in sphincter preservation rate, local recurrence rate, grade 3~4 acute toxicity, R0 resection rate and downstaging rate. Compared with SCRT, LCRT was associated with significant increase in the pCR rate [RR=0.49, 95%CI (0.31, 0.78), P=0.003]. Conclusions: In terms of sphincter preservation rate, local recurrence rate, grade 3~4 acute toxicity, R0 resection rate and downstaging rate, SCRT with delayed surgery is as effective as LCRT with delayed surgery for management of rectal cancer. LCRT significantly increased pCR rate compared with SCRT. Due to risk of bias and imprecision, further multi-center large sample RCTs were needed to confirm this conclusion.

  • Background: Surgical treatment of stage I non-small cell lung cancer (NSCLC) can be performed either by thoracotomy or by employing video-assisted thoracic surgery (VATS). The aim of this study was to evaluate the feasibility of VATS lobectomy for pathologic stage I NSCLC. Material and Methods: Between December 2003 and December 2007, 529 patients with pathologic stage I NSCLC underwent lobectomies (373 thoracotomy, 156 VATS). Patients in both groups were selected after being matched by age, gender and pathologic stage using propensity score method, to create two comparable groups: thoracotomy and VATS groups, and the overall survival, recurrence-free survival, complication and length of hospitalization were compared between these two groups. Results: After the patients were matched by age, gender and pathologic stage, 272 patients remained eligible for analysis, 136 in each group (mean age of 59.5 years; 70 men, 66 women; 80 stage IA, 56 stage IB). There was no statistical difference in other preoperative clinical characteristics between the two groups. No hospital mortality was observed in both groups. Overall 3-year survival rate was 97.4% in thoracotomy group and 96.6% in VATS groups (p=0.76). During the follow-up, 20 patients (14.7%) developed recurrence in thoracotomy group, including loco-regional recurrence in 7, distant metastasis in 13. In VATS group, 13 patients (9.6%) developed recurrence, including loco-regional recurrence in 4, distant metastasis in 9. Three-year recurrence-free survival rate was 81.8% in thoracotomy group and 85.3% in VATS groups (p=0.43). There was no significant difference in postoperative complications between thoracotomy and VATS groups (30 cases in 22 patients vs. 19 cases in 17 patients, p=0.65, odds ratio=1.19). The mean hospital stay of VATS group was 2 days shorter than that of thoracotomy group ($8.8{\pm}6.5$ days vs. $6.3{\pm}3.3$ days, p<0.05). Conclusion: VATS lobectomy for pathologic stage I lung cancer is a feasible operation with shorter hospitalization, while surgical outcome is comparable to thoracotomy lobectomy.

  • Purpose: The number of sore patients are increasing steadily, especially in old ages, chronic disease and paralytic patients. Most of patients need to surgical treatment. The aim of this paper is to assess clinical analysis of surgical treatment and to consider operative methods, complications, and recurrences.Methods: We reviewed the data from 82 consecutive patients with 101 pressure sores from March 2003 to May 2006 to discuss the occurrence rate and recurrence rate according to the site on the basis of the presence or absence of paraplegic and its etiology-the patients were categorized into three diagnostic groups: traumatic paraplegics(TP), nontraumatic paraplegics (NTP), and nontraumatic nonparaplegics(NTNP). We examined the sites and sizes of each lesions, patient's state, primary causes of pressure sore, operative methods as each sites and groups, occurrence of complications and recurrences on each groups. Results: In 82 patients, 52 patients were male, 30 patients were female. The male to female ratio was 1.7 :1. Mean age was 55.8 years. 27 patients were in TP group, 35 in NTP group, and 20 in NTNP group, respectively. The common site of sore were sacral area (50.5%), greater trochanteric area(15.8%) and ischial area(13.9%). In each group, incidence rate of recurrence and complication were 11.1%, 40.7% in TP, 5.7%, 5.7% in NTP and 15%, 45% in NTNP. Conclusion: Surgeons must consider the general condition of the patient and possibility of recurrence and returning of daily life. We propose that cutaneous flap, fasciocutaneous flap or skin graft as well as musculocutaneous flap be useful to repair of sore site as each patient's state.
