  • 배 경 : 새로운 항암제의 사용으로 비소세포 폐암에서 1차 항암 치료의 효과는 많이 향상 되었지만 많은 환자에서 치료 중 혹은 치료 후에 폐암이 진행하거나 재발되고 있다. 최근 환자의 체력 및 영양 상태의 향상으로 폐암의 진행 및 재발 후에도 신체 수행 상태(performance status)가 양호하여 2차 항암 치료의 대상 환자가 늘어나는 추세이다. 그러나 아직까지 표준화된 2차 항암 치료가 없는 실정으로 gemcitabine과 vinorelbine의 병합 요법은 비교적 다른 기전의 독성을 보여 병합 요법으로서의 가능성을 높여 주었다. 이에 저자들은 1차 항암 요법에 반응을 보이지 않거나 재발한 진행성 비소세포 폐암 환자를 대상으로 gemcitabine과 vinorelbine 병합 요법을 시행하여 치료 반응율, 생존율 및 독성에 대해 연구하였다. 대상 및 방법 : 2000년 12월부터 2003년 7월까지 고려대학교 의료원에 내원하여 비소세포 폐암으로 확진 받은 환자 중 진단 당시 IIIB, IV병기로 platinum을 기반으로 docetaxel 혹은 paclitaxel의 2제 복합 항암 요법을 1차 치료로 시행한 환자 중 진행하거나 재발한 환자들을 대상으로 gemcitabine과 vinorelbine 병합 요법의 치료 반응율, 생존율 및 독성을 분석하였다. 결 과 : Vinorelbine과 gemcitabine 병합 항암화학 요법은 총 215회가 시행 되었고, 환자당 시행된 평균값은 3.6회였다. 주요 반응에 해당하는 관해율은 10%였다. 1년 생존율은 32.9% 였으며, 생존 중앙값은 10.1개월이었다. 관해 지속 기간 중앙값은 3.8개월이었다. 대부분에서 경도의 오심과 구토, 탈모증이 관찰되었으며 WHO grade 3의 오심, 구토는 2예(3%)였으며, grade 4의 오심, 구토는 없었다. Grade 3 백혈구 감소가 33.3%, grade 4가 11.7%로 비교적 흔히 발생하였다. 호중구 감소가 동반된 폐렴으로 사망이 1예 보고되었다. 결 론 : Platinum을 기반으로 하는 1차 항암 치료 후 재발하거나 진행한 비소세포 폐암 환자에서 gemcitabine과 vinorelbine 병합 항암 요법은 비교적 효과적이고 안전한 항암 치료법으로 사료된다.

  • 목적 : 침윤성 방광암 환자를 대상으로 TURBT (Transurethral Resection of Bladder Tumor)과 유도 항암화학요법(neoadjuvant MCV chemotherapy) 후 방사선 항암화학 병용요법(cisplatin chemotherapy and radiotherapy)을 받은 환자에서 치료의 적응도, 국소 반응율, 방광 보존율과 생존율을 알아보고자 하였다. 대상 및 방법 : 1990년 10월부터 1998년 6월까지 TURBT 시행 후 병리 조직검사 상 침윤성 방광 이행상피암으로 진단 받은 병기 T2-T4, Grade II 환자 21명을 대상으로 하였다. 치료과정은 TURBT 후 4주 간격으로 2회의 유도 MCV(methotrexate, cisplatin, vinblastine) 복합 항암화학요법을 시행하고 그 후 cisplatin과 방사선 동시 병용요법을 시행하였다. 방사선치료는 $6\~15$ MV X-ray를 사용하여 하루 1.8 Gy씩 $39.6\~45\;Gy$를 전 골반에 $4\~5$주간에 걸쳐 조사하였다. 치료 종료 후 방광내시경을 통해 관해율을 판정하여 완전 관해인 경우 $1\~2$주 후 보강 방사선조사를 cisplatin과 병용하여 19.8 Gy를 시행하였다. 부분 관해인 경우 근치적 방광 절제술을 예정하였고 수술이 불가능한 경우에는 항암제 병용 강화 방사선치료를 받도록 하였다. 환자의 추적관찰기간은 $34\~67$개월로 중앙값이 49.5개월이었다. 결과 : 총 26명의 환자가 유도 항암화학요법을 위해 등록되었으며 유도 항암화학요법과 방사선 항암화학 병용요법을 완료한 환자는 21명$(81\%)$이었다. 유도 항암화학요법과 방사선 항암화학 병용요법 후 방광내시경을 통해 완전 관해 판정을 받은 환자는 21명 중 7명$(33\%)$이었고 부분 관해 환자는 14명$(67\%)$이었다. 완전 관해 환자 중 강화 항암제 병용 방사선 19.8 Gy를 받은 환자는 7명 중 6명$(85\%)$이었고, 이들 중 5명$(14\%)$은 재발 없이 방광을 보존하였다. 부분관해 환자중 1명이 근치적 방광적출술을 받았으며 3명이 TURBT와 2회의 MCV 항암요법을, 10명이 추가의 항암화학 방사선 병용요법을 받았다. 근치적 방광적출술을 받은 1명은 수술 소견상 방광 내 종양이 존재했으나 수술 후 재발이 없었다. 전체 21명의 환자중 12명$(58\%)$이 방광을 보존하면서 생존하고 있고 8명이 방광암으로 사망하였으며 1명이 다른 질병으로 사망하였다. 전체 환자의 중앙 생존기간은 27개월이며, 5년 생존율은 $55\%$ 였다. 유도 항암화학요법과 항암제 방사선치료 후 완전 관해 환자의 경우 5년 생존율은 $80\%$, 부분 관해 환자 $14\%$로 의미 있는 차이를 보였다(p=0.001). 유도 항암화학요법과 항암제 병용 방사선치료를 받은 환자에서 grade 3 이상의 혈액학적 부작용의 빈도는 각각 백혈구 감소증 6명$(29\%)$, 혈소판 감소증 1명$(4\%)$이었으며 이로 인한 화학요법의 지연은 1명$(4\%)$에서 관찰되었다. 결론 : 침윤성 방광암 환자에서 유도 항암화학요법 및 항암제 병용 방사선치료를 적용하여 방광 보존을 및 5년 생존율에 있어 만족할 만한 결과를 얻었다. 완전한 TURBT와 유도 MCV 항암요법과 cisplatin 방사선 병용요법에서 완전관해 여부가 방광보존가능성과 생존율에 영향을 미치는 요소로 생각되고 만약 완전관해를 이루지 못하면 근치적 방광적출술을 시행하는 것이 바람직할 것이다.

  • This study was designed to investigate the frequency of CYP2D6 polymorphisms and evaluate the association between genetic polymorphisms of CYP2D6 and tamoxifen therapeutic outcome in Thai breast cancer patients. We recruited 48 breast cancer patients who received adjuvant tamoxifen for evaluating CYP2D6 genetic polymorphisms using microarray-based technology. Associations between genotypes-phenotypes and disease free survival were analyzed. Median follow up time was 5.6 years. The mean age of the subjects was 50 years. The 3 common allelic frequencies were 43.8% ($^*10$), 36.5 ($^*1$) and 10.4% ($^*2$) which are related to extensive metabolizer (EM) and intermediate metabolizer (IM) with 70.8% and 29.2 %, respectively. No association between CYP2D6 genotypes and DFS was demonstrated. Nevertheless, exploratory analysis showed statistically significant shorter DFS in the IM group of post-menopause patients (HR, 6.85; 95%CI, 1.48-31.69; P=0.005). Furthermore, we observed statistically significant shorter DFS of homozygous $CYP2D6^*10$ when compared with heterozygous CYP2D6*10 and other genotypes (P=0.005). $CYP2D6^*10$ was the most common genotype in our subjects. Post-menopause patients with homozygous $CYP2D6^*10$ and IM have shorter DFS. To confirm this relationship, larger samples and comprehensively designed trials in Thailand are required.

  • Background: Third-generation tyrosine kinase inhibitors of the epidermal growth factor receptor (EGFR-TKIs) have proved efficacious in treating non-small cell lung cancer (NSCLC) patients with acquired resistance resulting from the T790M mutation. However, since almost 50% patients with the acquired resistance do not harbor the T790M mutation, retreatment with first- or second-generation EGFR-TKIs may be a more viable therapeutic option. Here, we identified positive response predictors to retreatment, in patients who switched to a different EGFR-TKI, following initial treatment failure. Methods: This study retrospectively reviewed the medical records of 42 NSCLC patients with EGFR mutations, whose cancers had progressed following initial treatment with gefitinib or erlotinib, and who had switched to a different first-generation EGFR-TKI during subsequent retreatment. To identify high response rate predictors in the changed EGFR-TKI retreatment, we analyzed the relationship between clinical and demographic parameters, and positive clinical outcomes, following retreatment with EGFR-TKI. Results: Overall, 30 (71.4%) patients received gefitinib and 12 (28.6%) patients received erlotinib as their first EGFR-TKI treatment. Following retreatment with a different EGFR-TKI, the overall response and disease control rates were 21.4% and 64.3%, respectively. There was no significant association between their overall responses. The median progression-free survival (PFS) after retreatment was 2.0 months. However, PFS was significantly longer in patients whose time to progression was ${\geq}10months$ following initial EGFR-TKI treatment, who had a mutation of exon 19, or whose treatment interval was <90 days. Conclusion: In patients with acquired resistance to initial EGFR-TKI therapy, switched EGFR-TKI retreatment may be a salvage therapy for individuals possessing positive retreatment response predictors.

  • Objectives: Cancer lethality is usually the result of local invasion and metastasis of neoplastic cell from the primary tumor. Because of their ability to degrade extracellular matrix components, matrix metalloproteinases (MMPs) and basic fibroblast growth factor (bFGF) have been implicated in the breakdown of basement membrane and underlying stroma, thereby facilitating tumor growth and invasion. It has been well established that MMPs and bFGF expression correlate with cervical lymph node metastasis, but studies on expression in the metastatic cervical lymph node itself are not enough. We have analyzed matrix metalloproteinases (MMPs) and basic fibroblast growth factor (bFGF) in squamous cell carcinoma of the head and neck and metastatic cervical lymph node, and evaluated their relationship and clinicophathologic significance. Material and Methods: 20 cases of squamous cell carcinoma of the head and neck were entered on the study of immunohistochemical stains for MMP-9 and bFGF in the obtained tissue from primary tumor and metastatic cervical lymph node. We analyzed the relationship between MMP-9, bFGF expression of the primary tumor and metastatic node with age, sex, T-stage, N-stage, histologic grade, pathologic stage and disease free survival. Results: Expression of MMP-9 and bFGF in cancer cell and metastatic lymph node was higher than that in normal cell and lymph node. According to histologic differentiation, expression of MMP-9 of the metastatic cervical lymph node was higher than primary tumor. Considering to other clinicopathologic factor, no statistical significance was seen in MMP-9 and bFGF. Conclusion: We found that expression of MMP-9 is higher in the metastatic lymph node than primary tumor in the poorly differentiated squamous cell carcinoma. But we don't find out the statistical significance in relation between bFGF and clinical factors. So we guess that some different mechanism of MMP-9 and bFGF in Head & Neck squamous cell carcinoma exist. Further studies will be necessary to establish their pathogenesis in the Head and Neck cancer.

  • Purpose: To investigate the current status of adjuvant chemotherapy (AC) regimens in Korea and the difference in efficacy of AC administered by surgical and medical oncologists in patients with stage II or III gastric cancers. Materials and Methods: We performed a retrospective observational study among 1,049 patients who underwent curative resection and received AC for stage II and III gastric cancers between February 2012 and December 2013 at 29 tertiary referral university hospitals in Korea. To minimize the influence of potential confounders on selection bias, propensity score matching (PSM) was used based on binary logistic regression analysis. The 3-year disease-free survival (DFS) rates were compared between patients who received AC administered by medical oncologists or surgical oncologists. Results: Between February 2012 and December 2013 in Korea, the most commonly prescribed AC by medical oncologists was tegafur/gimeracil/oteracil (S-1, 47.72%), followed by capecitabine with oxaliplatin (XELOX, 16.33%). After performing PSM, surgical oncologists (82.74%) completed AC as planned more often than medical oncologists (75.9%), with statistical significance (P=0.036). No difference in the 3-year DFS rates of stage II (P=0.567) or stage III (P=0.545) gastric cancer was found between the medical and surgical oncologist groups. Conclusions: S-1 monotherapy and XELOX are a main stay of AC, regardless of whether the prescribing physician is a medical or surgical oncologist. The better compliance with AC by surgical oncologists is a valid reason to advocate that surgical oncologists perform the treatment of AC for stage II or III gastric cancers.

  • Osteosarcoma in patients older than 40 years are rare, however they have different clinical, radiological and pathological features from those of younger patients. Sometimes accurate histologic diagnosis is not easy, which is important in determining the correct surgical treatment and appropriate chemotherapy. Since January 1995, 11 patients with osteosarcoma occurring in patients older than 40 years have been diagnosed, treated and followed up for more than 6 months. In contrast to osteosarcoma in children and adolescents, only 4 cases(36.4%) were conventional types, while the others included 2 malignant fibrous histiocytoma-like types, 2 small cell types, 2 periosteal osteosarcomas and 1 giant cell-rich type. Seven cases showed purely osteolytic or predominantly osteolytic bony lesions and 8 were in Enneking stage IIB. Performed surgical treatments included 2 amputations, 6 wide resections and reconstructions, and one curettage and autogenous bone graft. In the remaining 2 cases, definitive surgical treatments included not carried out because of old age, multifocal involvement or poor medical tolerance. Neoadjuvant and adjuvant chemotherapies were performed in 9 of 11 patients. At last follow-up, there were 6 continuously disease-free survivals, 3 alive with diseases and 2 died of diseases. The overall cumulative 4-year survival rate calculated using Kaplan-Meier's productlimit method was 59.3%. For improved oncologic outcomes and survivals, early and accurate diagnosis, surgical treatment with adequate margin and neoadjuvant and adjuvant chemotherapy will be necessary.

  • Purpose: To compare the safety and efficacy of first-line chemotherapy regimen with or without doxorubicin in treating patients with advanced soft tissue sarcoma (STS). Patients and Methods: We retrospectively analyzed a cohort of 56 patients histologically confirmed with STS who were treated at Jiangsu Cancer Hospital and Research Institute from July 2011 to June 2012.The basic element of first line chemotherapy contained epirubicin in group B and lacked epirubicin in group A. Response was assessed using RECIST criteria. The Kaplan-Meier method was used to estimate progress free survival (PFS). Results: According to RECIST criteria, patients in group treated by chemotherapy without epirubicin, the objective response (OR) ratio was 6.5 % (CR0%+PR6.5%). Disease control rate (DCR=CR+PR+SD) was 25.8% with a median follow-up of 14.6 months, including 2 patients achieving a partial response (PR 6.5%) and a stable response (SD 19.4%) in 6. In group B with epirubicin based regimens, no patient had complete response, PR (28 %) was observed in 7 and SD (24 %) in 6. DCR was observed in 13 patients (52%). By Fisher's exact test, the DCR difference between the two groups was statistically significant (p=0.046). In group A, median PFS was 3.0 months (95%CI:2.1-3.8), compared with 4.0 months (95% CI:3.03-4.97) in group B (p=0.0397 by log-rank test). Epirubicin based chemotherapy and ECOG performance status 0-1 were identified as favorable factors for progression in our cohort of patients. Differences of nonhematologic and hematologic toxicities were not statistically significant between the two groups, and the addition of epirobicin was not associated with cardiac toxicity (p=0.446). Conclusion: Our study demonstrates that epirubicin-based chemotherapy is effective and well tolerated, and is superior to chemotherapy without epirubicin regarding efficacy. Therefore it is recommended that epirubicin-based chemotherapy should be considered as first line for patients with advanced STS.
