대장암의 치료에 여러 약물이 사용되지만, 5-FU는 오랫동안 대장암의 항암치료의 근간이 되고 있다. Capecitabine은 경구 복용하는 5-FU의 전구체로서, 최근 전이성 대장암의 치료에 사용이 증가되고 있는 약물이다. 저자들은 전이성 대장암 환자에서 고식적인 항암화학요법으로 1차 치료로서 FOLFOX에 좋은 반응을 보였으나, 부작용으로 중단 후 2차 치료로서 Capecitabine 단독요법만을 시행하였음에도 지속적으로 좋은 반응을 보이며 추적관찰하고 있는 사례를 문헌고찰과 함께 보고하는 바이다.

식생활의 서구화와 대장암 검진의 증가로 인하여 국내의 대장암 유병률은 지속적으로 증가하고 있으며, 최근 보고에 의하면 남자에서는 종양 발생률 2위, 여자에서는 종양 발생률의 3위를 차지하고 있다. 비록 대장내시경이 대장암의 진단과 선별검사에 아주 효과적인 방법이지만, 여전히 대장암의 20-25%는 이미 진단 당시에 전이를 동반하고 있는 것으로 되어 있다. 최근 10년 동안 이러한 전이성대장암의 고식적인 치료로 irinotecan과 oxaliplatin 등의 약제들의 개발과 이들의 다양한 조합에 관련된 연구들이 보고되어 왔으며, 분자생물학적인 발전에 힘입은 표적 치료제의 개발과 이에 대한 다양한 연구들은 향후에도 진행성대장암 환자들의 종양 반응률과 생존기간을 증가시킬 것으로 기대된다.

Background: Palliative chemotherapy with cisplatin/5-fluorouracil (5FU) is the commonest regimen employed for metastatic and recurrent head and neck squamous cell carcinoma (SCCHN) and nasopharyngeal carcinoma (NPC). However, this regimen is cumbersome requiring 5 days of admission to hospital. Carboplatin/5FU may be an alternative regimen without compromising survival and response rates. This study aimed to compare the efficacy and toxicity of carboplatin/5FU regimen with the cisplatin/5FU regimen. Materials and Methods: This retrospective study looked at patients who had palliative chemotherapy with either cisplatin/5FU or carboplatin/5FU for metastatic and recurrent SCCHN and NPC. It included patients who were treated at UKMMC from $1^{st}$ January 2004 to $31^{st}$ December 2009 with either palliative IV cispaltin 75 $mg/m^2$ D1 only plus IV 5FU 750 $mg/m^2$ D1-5 infusion or IV Carboplatin AUC 5 D1 only plus IV 5FU 500 $mg/m^2$ D1-2 infusion plus IV 5FU 500 $mg/m^2$ D1-2 bolus. The specific objectives were to determine the efficacy of palliative chemotherapy in terms of overall response rate (ORR), median progression free survival (PFS) and median overall survival (OS) and to evaluate the toxicities of both regimens. Results: A total of 41 patients were eligible for this study. There were 17 in the cisplatin/5FU arm and 24 in the carboplatin/5FU arm. The ORR was 17.7 % for cisplatin/5FU arm and 37.5 % for carboplatin/5FU arm (p-value=0.304). The median PFS was 7 months for cisplatin/5FU and 9 months for carboplatin/5FU (p-value=1.015). The median OS was 10 months for cisplatin/5FU arm and 12 months for carboplatin/5FU arm (p-value=0.110). There were 6 treatment-related deaths (6/41=14.6%), four in the carboplatin/5FU arm (4/24=16.7%) and 2 in the cisplatin/5FU arm (2/17=11.8%). Grade 3 and 4 hematologic toxicity was also more common with carboplatin/5FU group, this difference being predominantly due to grade 3-4 granulocytopenia (41.6% vs. 0), grade 3-4 anemia (37.5% vs. 0) and grade 3-4 thrombocytopenia (16.6% vs. 0). Conclusions: Carboplatin/5FU is not inferior to cisplatin/5FU with regard to its efficacy. However, there was a high rate of treatment-related deaths with both regimens. A better alternative needs to be considered.

Background: Health-related quality of life (HRQL) is a fundamental outcome in oncology patients and quality of life (QOL) assessment requires clinically relevant questionnaires. The purpose of this study was translation and definition of measurement properties and the clinical validity of Quality of Life Questionnaire (QLQ)-OG25 module in Persian patients with oesophagus, oesophagogastric junction (OGJ) or gastric cancers. Materials and Methods: The translation procedure followed European Organization for Research and Treatment of Cancer (EORTC) guidelines. Both EORTC QLQ-OG25 and a core questionnaire (EORTC QLQ-C30) were administered to patients with oesophagus (150), OG junction (93) and gastric (32) cancer undergoing multi-modal treatments. Convergent and discriminant validity, Cronbach's alpha coefficient and known-groups comparisons were used to examine reliability and validity. Results: In all, 275 patients (mean age 62 years) completed both questionnaires. Compliance rate was high and the questionnaire module was well accepted. We found good reliability for multi-item subscales of QLQ-OG25 (Cronbach's alpha coefficients 0.76-0.89). About 73% had TNM staging and scales distinguished between clinically distinct groups of patients. However, patients in palliative group experienced compromised functional status and worse treatment-associated symptoms than those in the potentially curative group. Test-retest scores were consistent. Multi-trait scaling analysis demonstrated good convergent and discriminant validity. Conclusions: Overall, the Persian version of QLQ-OG25 demonstrated psychometric and clinical validity that supports its application as a supplement to the original tool (EORTC QLQ-C30) when assessing HRQL in patients with upper-gastrointestinal (GI) cancer both in curative and palliative phases.

Objective : The cervicothoracic junction (CTJ) is a biomechanically and anatomically complex region that has traditionally posed problems for surgical access. In this retrospective study, we describe our clinical experiences of the treatment of metastatic spinal tumors at the CTJ and the results. Methods : From June 2006 to December 2011, 23 patients who underwent surgery for spinal tumors involving the CTJ were enrolled in our study. All of the patients were operated on through the posterior approach, and extent of resection was classified as radical, debulking, and simple neural decompression. Adjuvant radiation therapy (RT) was also considered. Visual analog scale score for pain assessment and Medical Research Council (MRC) grade for motor weakness were used, while pre- and post-operative performance status was evaluated using the Eastern Cooperative Oncology Group (ECOG). Results : Almost all of the patients were operated using palliative surgical methods (91.3%, 21/23). Ten complications following surgery occurred and revision was performed in four patients. Of the 23 patients of this study, 22 showed significant pain relief according to their visual analogue scale scores. Concerning the aspect of neurological and functional recovery, mean MRC grade and ECOG score was significantly improved after surgery (p<0.05). In terms of survival, radiation therapy had a significant role. Median overall survival was 124 days after surgery, and the adjuvant-RT group (median 214 days) had longer survival times than prior-RT (63 days) group. Conclusion : Although surgical procedure in CTJ may be difficult, we expect good clinical results by adopting a palliative posterior surgical method with appropriate preoperative preparation and postoperative treatment.

Purpose: The role of radiotherapy (RT) was largely deserted after the introduction of platinum-based chemotherapy, but still survival rates are disappointingly low. This study focuses on assessing the clinical efficacy of RT in relation to chemotherapy resistance. Materials and Methods: From October 2002 to January 2015, 44 patients were diagnosed with epithelial ovarian cancer (EOC) and treated with palliative RT for persistent or recurrent EOC. All patients received initial treatment with optimal debulking surgery and adjuvant platinum-based chemotherapy. The biologically effective dose (BED) was calculated with ${\alpha}/{\beta}$ set at 10. Ninety-four sites were treated with RT with a median BED of 50.7 Gy (range 28.0 to 79.2 Gy). The primary end-point was the in-field local control (LC) interval, defined as the time interval from the date RT was completed to the date any progressive or newly recurring disease within the RT field was detected on radiographic imaging. Results: The median follow-up duration was 52.3 months (range 7.7 to 179.0 months). The 1-year and 2-year in-field LC rates were 66.0% and 55.0%, respectively. Comparisons of percent change of in-field tumor response showed similar distribution of responses among chemoresistant and chemosensitive tumors. On multivariate analysis of predictive factors for in-field LC analyzed by sites treated, $BED{\geq}50Gy$ (hazard ratio, 0.4; confidence interval, 0.2-0.9; p = 0.025) showed better outcomes. Conclusion: Regardless of resistance to platinum-based chemotherapy, RT can be a feasible treatment modality for patients with persistent of recurrent EOC. The specific role of RT using updated approaches needs to be reassessed.

Purpose: This study investigated knowledge of and attitudes toward advance directives (ADs) among middle-aged women in South Korea, their willingness to write ADs in the future, and the factors related to knowledge of and attitudes toward ADs. Methods: Data were collected using a self-administrated questionnaire completed by 154 middle-aged women aged 50 to 64 from February to March 2020. The questionnaire asked about participants' knowledge of and attitude toward ADs, willingness to write ADs in the future, experiences with life-sustaining treatment within their families, experience making decisions about life-sustaining treatment, and demographic characteristics. Results: Scores for both knowledge of and attitude toward ADs were relatively high. About 60% of participants gave wrong answers when asked if attorneys were required for writing ADs. A higher knowledge score was significantly associated with a higher attitude score (r=0.227, P<0.01). The women were more likely to be willing to write ADs in the future when they reported a middle income level rather than a lower income level (odds ratio [OR]=5.952, P<0.01), considered themselves unhealthy (OR=5.873, P<0.01), and graduated college or higher (OR=4.096, P<0.05). Furthermore, women who thought that ADs would have an impact on treatment (OR=1.869, P<0.05) and on their families (OR=1.447, P<0.05) were more likely to be willing to write an AD. Conclusion: This study shows that wrong information about ADs persists among middle-aged women, and significant factors associated with knowledge of and attitude toward ADs were identified. Targeted education programs about ADs need to be developed for middle-aged women.
