Clinicopathological Characteristics and Factors Affecting Recurrence of Ductal Carcinoma In Situ in Korean Women

Purpose: As breast cancer screening becomes more popular in Korea, incidence of ductal carcinoma in situ (DCIS) of breast has increased to more than 10% of all breast cancer diagnosed. We aimed to show the clinicopathological characteristics and factors affecting recurrence of DCIS in Korean women. Methods: We retrospectively reviewed 152 DCIS patients who underwent breast conserving surgery in Seoul National University Hospital between January 1995 and December 2005. Results: Mean age at diagnosis was 46.7 years (24 to 66 years). Mean follow up duration of the patients was 73.82 months (0.80 to 168.43 months). Recurrence of disease occurred in 19 (12.5%) patients: 2 in contralateral breast, 15 in ipsilateral breast, and 2 in axilla. One patient showed ipsilateral breast recur after excision of axillary metastasis. Eight (42.11%) of all recurrence was infiltrating ductal carcinoma and one of them showed bone metastasis during follow up. In an multivariate analysis of factors affecting recurrence, younger age at diagnosis and omission of radiotherapy had significant association with recurrence (p=0.005 and p=0.002, respectively). However, tumor size (p=0.862), microinvasion (p=0.988), histologic grade (p=0.157), estrogen receptor status (p=0.401) and resection margin status (p=0.112) were not significantly correlated with recurrence. There was no breast cancer associated mortality. Conclusion: In this study, we found that the younger age at diagnosis and omission of adjuvant radiotherapy are independent predictors of recurrence in Korean DCIS patients.Pinder SE, 2010, BRIT J CANCER, V103, P94, DOI 10.1038/sj.bjc.6605718Bundred NJ, 2010, CLIN CANCER RES, V16, P1605, DOI 10.1158/1078-0432.CCR-09-1623Virnig BA, 2010, J NATL CANCER I, V102, P170, DOI 10.1093/jnci/djp482Allegra CJ, 2010, J NATL CANCER I, V102, P161, DOI 10.1093/jnci/djp485Thomas J, 2010, BRIT J CANCER, V102, P285, DOI 10.1038/sj.bjc.6605513Collins LC, 2009, AM J SURG PATHOL, V33, P1802Hughes LL, 2009, J CLIN ONCOL, V27, P5319, DOI 10.1200/JCO.2009.21.8560Shah DN, 2009, BREAST J, V15, P649, DOI 10.1111/j.1524-4741.2009.00838.xGoodwin A, 2009, BREAST, V18, P143, DOI 10.1016/j.breast.2009.04.003Chung YS, 2009, J BREAST CANCER, V12, P106, DOI 10.4048/jbc.2009.12.2.106Dunne C, 2009, J CLIN ONCOL, V27, P1615, DOI 10.1200/JCO.2008.17.5182Kuerer HM, 2009, J CLIN ONCOL, V27, P279, DOI 10.1200/JCO.2008.18.3103Luini A, 2009, BREAST CANCER RES TR, V113, P397, DOI 10.1007/s10549-008-9929-0von Smitten K, 2008, J SURG ONCOL, V98, P585, DOI 10.1002/jso.21038Ko SS, 2008, J SURG ONCOL, V98, P318, DOI 10.1002/jso.21110Sakorafas GH, 2008, CANCER TREAT REV, V34, P483, DOI 10.1016/j.ctrv.2008.03.001Morrow M, 2008, ANN SURG ONCOL, V15, P2641, DOI 10.1245/s10434-008-0083-zIntra M, 2008, ANN SURG, V247, P315, DOI 10.1097/SLA.0b013e31815b446bAllred DC, 2008, CLIN CANCER RES, V14, P370, DOI 10.1158/1078-0432.CCR-07-1127RHEE J, 2008, BMC CANCER, V8, pNIL19, DOI DOI 10.1186/1471-2407-8-307Moore KH, 2007, ANN SURG ONCOL, V14, P2911, DOI 10.1245/s10434-007-9414-8Sontag L, 2005, J THEOR BIOL, V232, P179, DOI 10.1016/j.jtbi.2004.08.002Boland GP, 2003, BRIT J SURG, V90, P426, DOI 10.1002/bjs.4051Vicini FA, 2002, J CLIN ONCOL, V20, P2736, DOI 10.1200/JCO.2002.07.137Neuschatz AC, 2002, CANCER, V94, P1917, DOI 10.1002/cncr.10460Bartelink H, 2001, NEW ENGL J MED, V345, P1378Bijker N, 2001, J CLIN ONCOL, V19, P2263LEE HD, 2001, J KOREAN SURG SOC, V60, P495FRYKBERG ER, 1997, BREAST J, V3, P227

Factors Affecting the Ipsilateral Breast Tumor Recurrence after Breast Conserving Therapy in Patients with T1 and T2 Tumors

본 논문은 2008년 대한외과학회 추계학술대회에서 구연 발표되었음.Purpose: Nearly half of all breast cancers are treated with breast conserving therapy (BCT). The purpose of this study was to identify the risk factors for ipsilateral breast tumor recurrence (IBTR) after BCT in T1 and T2 breast cancer patients. Methods: The medical records of 294 T1 or T2 breast cancer patients who underwent BCT at Seoul National University Hospital between January 1998 and December 2002 were retrospectively reviewed. Kaplan-Meier curves and Cox proportional regression analysis were used to identify the significant clinicopathologic factors that influence IBTR. Results: Among the 294 patients, 12 patients (4.8%) developed IBTR after a median follow-up of 82 months. Univariate analysis demonstrated that younger age (<= 35 year) had significant associations with IBTR (p=0.006). Tumor size, lymph node status, histologic grade, extensive intraductal component, lymphovascular invasion, and close resection margins were not significant factor associated with IBTR. The triple negative breast cancer subtype also did not have significant association with IBTR. Multivariate analysis showed that the younger age at diagnosis was a significant predictor of IBTR with a FIR of 3.86 (p=0.036; 95% CI, 1.09-13.60). Conclusion: Younger age at diagnosis (<= 35) may be associated with an increased risk of IBTR in patients who underwent BCT.Han W, 2010, BREAST CANCER RES TR, V119, P193, DOI 10.1007/s10549-009-0388-zBenson JR, 2009, LANCET, V373, P1463Luini A, 2009, BREAST CANCER RES TR, V113, P397, DOI 10.1007/s10549-008-9929-0Nguyen PL, 2008, J CLIN ONCOL, V26, P2373, DOI 10.1200/JCO.2007.14.4287Lee JW, 2007, J BREAST CANCER, V10, P206Dent R, 2007, CLIN CANCER RES, V13, P4429, DOI 10.1158/1078-0432.CCR-06-3045KANG SH, 2007, J KOREAN SURG SOC, V73, P385Haffty BG, 2006, J CLIN ONCOL, V24, P5652, DOI 10.1200/JCO.2006.06.5664Ahn SH, 2006, BREAST CANCER RES TR, V99, P209, DOI 10.1007/s10549-006-9188-xWapnir IL, 2006, J CLIN ONCOL, V24, P2028, DOI 10.1200/JCO.2005.04.3273Komoike Y, 2006, CANCER, V106, P35, DOI 10.1002/cncr.21551Abe O, 2005, LANCET, V366, P2087Noh WC, 2005, WORLD J SURG, V29, P1001, DOI 10.1007/s00268-005-7928-4Kim KJ, 2005, JPN J CLIN ONCOL, V35, P126, DOI 10.1093/jjcolyhi039Han WS, 2004, BMC CANCER, V4, DOI 10.1186/1471-2407-4-82MORROW M, 2004, DIS BREAST, P719Arriagada R, 2003, ANN ONCOL, V14, P1617, DOI 10.1093/annonc/mdg452Singletary SE, 2002, AM J SURG, V184, P383Veronesi U, 2002, NEW ENGL J MED, V347, P1227Fisher B, 2002, NEW ENGL J MED, V347, P1233Freedman GM, 2002, J CLIN ONCOL, V20, P4015, DOI 10.1200/JCO.2002.03.155Haffty BG, 2002, LANCET, V359, P1471Jobsen JJ, 2001, EUR J CANCER, V37, P1820Sasson AR, 2001, CANCER, V91, P1862Voogd AC, 2001, J CLIN ONCOL, V19, P1688Park CC, 2000, J CLIN ONCOL, V18, P1668Freedman G, 1999, INT J RADIAT ONCOL, V44, P1005Peterson ME, 1999, INT J RADIAT ONCOL, V43, P1029SUH CO, 1997, J KOREAN SOC THER RA, V15, P331BORGER J, 1994, J CLIN ONCOL, V12, P653WAZER DE, 1992, J CLIN ONCOL, V10, P356SOLIN LJ, 1991, INT J RADIAT ONCOL, V21, P279JACQUEMIER J, 1990, BRIT J CANCER, V61, P873VERONESI U, 1990, EUR J CANCER, V26, P671FOURQUET A, 1989, INT J RADIAT ONCOL, V17, P719LOCKER AP, 1989, BRIT J SURG, V76, P890

The Measurements of Dosimetry of Cs -137 Sources with the Fletcher-Suit Applicator

Fletcher'Suit applicator was designed with specific purpose for the treatment of carcinoma of the uterine cervix and has been widely used for the intracavitary radiation. In many instances. calculation of dosage distributions about intracavitary applicator doses not require corrections for radiation by applicator. However. in the case of the Fletcher-Suit applicator loaded with cesium in place of radium tubes. correction should be made for absorption by the applicator. So the measurements of transmission ratios has made in polystyrene phantom using PC•12 Computer densitometer. The results show that there is a 10%~30% reduction dose to the region of the hladder trigone and anterior rectu

A Study on Radiation Effect on Microvasculature of the Liver in Rat

Microarigiography of rat liver was performed with arterial and venous infusion of barium solution to evaluate the vascular alterations in radiation injury of the liver in a total of 53 rats. Part of liver, right to midline, received a single dose of 2,000 rad using Co-60 teletherapy unit with field size of 4 x 4cm at 60cm SSD. The dose rate was 127.2 rads per minute. Microangiography was performed at, 1, 2, 4, 8, 12 and 16 weeks following irradiation. The results are as follows: 1. After irradiation, mieroangiographic findings of hepatic artery and portal vein were tortuosity, beaded appearance and narrowing of the lumen. And these findings appeared at 2 to 4 weeks after irradiation and progressed with lapse of time. 2. Hepatic vein showed no remarkable abnormality in microangiography. 3. Sinusoids showed slight widening and irregularity. These findings were present for the first 4 weeks and thereafter disappeared. 4. Microangiographic findings generally well corre-lated with histologic findings. 5. In conclusion, in radiation injury of rat liver with a single dose of 2,000rad, the principal changes were observed in hepatic artery and por-tal vein

항문암의 치료성적: 비수술적방법과 수술적방법의 결과 비교

목적 : 항문암의 치료에 있어 고전적으로는 복회음부절제술이 주된 치료였으나 현재는 화학방사선병용요법이 주된 치료방법으로 정립되었다. 저자들은 서울대학교병원에서 항문암으로 치료 받은 환자의 임상적 특성을 조사하고, 치료방법에 따른 치료성적과 예후인자를 분석하고자 하였다. 대상 및 방법 : 1979년 8월부터 1990년 7월까지 서울대학교병원 치료방사선과에서 근치적 또는 수술 후 방사선 치료를 받은 42명의 환자를 대상으로 후향적으로 분석하였다. 표피양암종이 38명으로 방사선치료가 4명에서, 복회음부절제술 및 수술 후 방사선치료±화학요법이 19명에서, 화학방사선요법이 15명에서 시행되었다. 화학방사선요법은 복합화학요법(5−FU1,000mg/m2D1\~5,cisplatin60mg/m2D1)을 3회 시행 후 원발병소 및 영역림프절에 50.4 Gy를 조사하였고, 양측 서혜림프절에도 동일양을 조사하였다. 잔존암이 있는 경우 복합화학요법을 3회 추가 실시하였다. 중앙추적기간은 85개월이었다. 결과 : 전체 항문암 환자의 5년 생존율은 80.3%이었다. 치료방법에 따른 5년 생존율은 복회음부절제술 및 수술 후 방사선치료±화학요법군, 화학방사선요법군에서 각각 88.9%,79.4%이었으며 두군간의 생존율의 차이의 통계적인 의미는 없었다(p=0.495). 화학방사선요법을 시행 받은 환자군에서의 항문보존율은 86.7%였다. 예후인자 중 단변량분석에서는 연령(p=0.0164)과 수행능력(p=0.0007)이 유의성을 보였으며, 다변량분석에서는 연령(p=0.0426)과 수행능력(p=0.0068) 및 서혜림프절 전이여부(p=0.0093)가 통계학적으로 유의하였다. 결론 : 항문암의 치료에 있어서 화학방사선요법을 시행할 경우 기존에 알려진 바와 같이 복회음부절제술과 유사한 생존율을 보이며, 항문기능을 보존할 수 있는 치료 방법임을 확인할 수 있었다. 나아가 병행화학요법이 아닌 선행화학요법을 시행하여 수반되는 합병증을 줄일 수 있는 가능성을 확인하였다. Purpose : This study was undertaken to analyze the efficacy and sphincter preservation rate of platinum based neoadjuvant chemotherapy Plus radiotherapy versus abdominoperineal resection and Postoperative radiotherapy for anal cancer. Materials and Methods : Data of forty-two patients with anal cancer were retrospectively analyzed. Among thirty-eight patients with epidermoid histology, four patients received radiotherapy, and nineteen patients received abdominoperineal resection and adjuvant radiotherapy with or without chemotherapy (APR+RT±CT), and fifteen patients received neoadjuvant chemotherapy and radiotherapy (CRT). The CRT regimen was composed of three cycles of 5-fluorouracil (1,000mg/m2bolusonD1\~5) and cisplatin (60mg/m2bolusonD1) followed by 50.4 Gy to the tumor bed and regional lymphatics over 5.5 weeks. Both inguinal lymphatics were treated with an identical dose schedule. Residual disease was treated with an additional three cycles of identical adjuvant chemotherapy. An identical dose schedule was used for post-operative radiotherapy. Median follow-up period was eighty-five months. Results : Overall five-year survival rates were 80.3%, 88.9 and 79.4% for entire patients, APR+RT±CT group, and the CRT group, respectively. No significant difference was found between the two groups (p=0.49). Anus preservation rate for the CRT group was 86.7%. Age (0=0.0164) and performance status (p=0.0007) were found to be significant prognostic factors by univariate analysis. Age (p=0.0426), performance status (p=0.0008), and inguinal lymph node metastasis (e=0.0093) were statistically significant prognostic factors by multivariate analysis. No case of RTOG grade 3 complication or higher was reported. Conclusion : This and other recent studies have shown that combined chemotherapy plus radiotherapy for anal cancer results in a high rate of anal sphincter preservation as well as local control and survival. Furthermore, neoadjuvant use of chemotherapy with a cisplatin based regimen rather than a concurrent regimen may lead to a decrease in complications

The Impact of Primary Tumor Resection on the Survival of Patients with Stage IV Breast Cancer

Purpose The main treatment for stage IV breast cancer is currently systemic therapy. Surgical resection of the primary tumor is usually done for treating the tumor-related complications Recent studies have suggested that surgery may improve the long-term survival of stage IV breast cancer patients We evaluated the impact of the primary surgical resection site on the survival of stage IV breast cancer patients. Methods We reviewed the records of the stage IV breast cancer patients who were treated at Seoul University Hospital between April 1992 and December 2007 The tumor and clinical characteristics, the type of treatments and the overall survival were compared between the surgically versus nonsurgically treated patients. Results. Of the 198 identified patients, 110 (55 8%) received surgical excision of their primary tumor and 88 (44 2%) did not The mean survival was 67 months vs. 42 months for the surgically treated patients vs the patients without surgery, respectively (p=0 0287) On a multivariate analysis with using the Cox model and after adjusting for the estrogen receptor status, visceral metastases, the number of metastatic sites and trastuzumab treatment, surgery was an independent factor for improved survival (hazard ratio, 0.55; 95% confidence interval, 0.31-0.97; p=0.041). Conclusion Surgical resection of the primary tumor in stage IV breast cancer patients was independently associated with improved survival. Randomized prospective trials are needed to firmly recommend surgical resection of the primary tumor in stage IV breast cancer patients본 연구는 폐암, 유방암/난소암 유전체 연구센터의 연구비를 지원받아 수행 되었음(01-PJ3-PG6-01GN07-0004).Bafford AC, 2009, BREAST CANCER RES TR, V115, P7, DOI 10.1007/s10549-008-0101-7Blanchard DK, 2008, ANN SURG, V247, P732, DOI 10.1097/SLA.0b013e3181656d32*KOR BREAST CANC S, 2008, BREAST CANC FACTS FI, V1, P5Fields RC, 2007, ANN SURG ONCOL, V14, P3345, DOI 10.1245/s10434-007-9527-0Gnerlich J, 2007, ANN SURG ONCOL, V14, P2187, DOI 10.1245/s10434-007-9438-0Rapiti E, 2006, J CLIN ONCOL, V24, P2743, DOI 10.1200/JCO.2005.04.2226Morrow M, 2006, J CLIN ONCOL, V24, P2694, DOI 10.1200/JCO.2006.05.9824Babiera GV, 2006, ANN SURG ONCOL, V13, P776, DOI 10.1245/ASO.2006.03.033Hotta T, 2006, ANTICANCER RES, V26, P1377Abe O, 2005, LANCET, V366, P2087Andre F, 2004, J CLIN ONCOL, V22, P3302, DOI 10.1200/JCO.2004.08.095Giordano SH, 2004, CANCER, V100, P44, DOI 10.1002/cncr.11859Khan SA, 2002, SURGERY, V132, P620, DOI 10.1067/msy.2002.127544Flanigan RC, 2001, NEW ENGL J MED, V345, P1655Demicheli R, 2001, BRIT J CANCER, V85, P490Dauplat J, 2000, SEMIN SURG ONCOL, V19, P42Overgaard M, 1999, SEMIN RADIAT ONCOL, V9, P292DOGHETTO GB, 1999, AM SURGEON, V65, P352BLAND KI, 1998, BREAST COMPREHENSIVE, V2Ragaz J, 1997, NEW ENGL J MED, V337, P956OREILLY MS, 1994, CELL, V79, P315FISHER B, 1989, CANCER RES, V49, P1996*NAT CANC I, BREAST CANC TREATM P
