The purpose of this study was to investigate whether whole-liver radiotherapy plus a tumor-boost dose with concurrent chemotherapy is beneficial for colorectal cancer patients with massive and multiple liver metastases. From January 2007 to December 2012, 19 patients who exhibited massive (with a longest diameter > 5 cm) and invasive liver metastases and multiple metastases were treated with radiotherapy and concurrent chemotherapy. The total radiation dose was 53.4 Gy (range 38.8 Gy-66.3 Gy). All of the patients received a continuous intravenous dose of 5 fluorouracil (5-FU) 225 mg/m2 concurrently with radiation. The median survival time was 19 months. The 1- and 2- year overall survival rates were 78.3% and 14.3%, respectively. Of all of the patients who presented with abdominal pain, 100% experienced a decrease in pain. Decreases in the rates of ascites and jaundice were confirmed by ultrasound and bilirubin levels. No cases of Grade 4 or 5 acute or late toxicity were recorded. There were only two cases of Grade 3 toxicity (elevated bilirubin). These data provide evidence that whole-liver radiotherapy plus a tumor-boost dose with concurrent chemotherapy is beneficial for colorectal cancer patients with massive and multiple liver metastases.

Purpose: The purpose of this study was to analyze end-of-life care practices in lung disease patients with physician orders for life-sustaining treatment (POLSTs). Methods: We retrospectively analyzed data from medical records regarding the end-of-life care practices of POLST decisions for patients with lung disease hospitalized at a tertiary hospital in Seoul, South Korea. Data were collected from January 1 to June 30, 2021. Results: Of 300 total patients, 198 had lung cancer (66.0%) and 102 had non-malignant lung diseases (34.0%). A POLST was written for 187 patients (62.3%), and an advance directive was written for 20 patients (6.7%). Subsequent treatments were hemodialysis in 13 patients (4.3%), surgery in 3 patients (1.0%), and cardiopulmonary cerebral resuscitation in 1 patient (0.3%). Among cancer patients, chemotherapy was performed in 11 patients (3.7%), targeted therapy in 11 patients (3.7%), immunotherapy in 6 patients (2.0%), and radiation therapy in 13 patients (4.3%). Depending on the type of lung disease, types of treatment differed, including hemodialysis, ventilators, bilevel positive airway pressure, high-flow nasal cannulas, nebulizers, enteral nutrition, central line, inotropic agents, and opioids. Conclusion: Although the goals of hospice care are the same whether a patient has lung cancer or a non-malignant lung disease, because the characteristics of the respective diseases differ, end-of-life care practices and hospice approaches must be considered differently.

Background: Male breast cancer (MBC) is a rare disease that accounts for less than 1% of all cancers in men and less than 1% of all diagnosed breast cancers. In this study, we retrospectively evaluated the clinicopathological features, treatment options and overall survival in Kurdish MBC cases. Materials and Methods: Seventeen MBC were referred to Department of Radiation Oncology in Imam Reza Hospital, Kermanshah, Iran, between 2010 and 2016. Immunohistochemical analysis was performed for ER, PR and Her2 biomarkers and FISH for those with Her2 2+. Median follow-up period was 30 months (2-65 months). We excluded from the study patients who did not have follow-up after initial diagnosis. Treatment methods were chemotherapy, radiotherapy, hormonal therapy, target therapy and palliative care. Survival was estimated by the Kaplan Meier method (Prism 5). Results: The mean age at diagnosis was $49.24{\pm}17$ years (range, 24-85 years). Grade II was the most grade in MBC (65%). Fourteen patients (82%) had invasive ductal carcinoma, one (6%) had ductal carcinoma in situ and 2 (12%) had invasive papillary. ER, PR and Her2 were significantly positive in 14/17, 8/17 and 2/17 cases, respectively. The treatment included modified radical mastectomy for most patients. Chemotherapy with TAC and CEF regimens was delivered to 15/17 cases. Tamoxifen therapy was delivered to 14/17 cases. Three stage IV patients received Avestin and two with Her2 3+ were given Trastuzumab (Herceptin). Patients received adjuvant radiotherapy following surgery and chemotherapy. The site of metastasis was the bone in 2 cases, lung in 1 case and liver in 1 case. Zoledronic acid (Zometa) was prescribed for patients with bone metastasis. Five-year overall survival rate was 64%. Conclusions: MBC is rare. Thus, we need larger studies are in collaboration with several research centers in the field of breast cancer. ER positive, grade II of invasive ductal carcinoma, stage II and right side happened more with MBC. Overall survival is similar to other studies.

목적 : 위암의 간문맥 임파절 재발로 발생한 악성 폐쇄성 황달치료에 있어서 외부 방사선치료의 효과를 평가해 보고 치료의 결과에 영향을 미칠 수 있는 요인을 알아보고자 하였다. 방법 : 1984년부터 1993년까지 위암의 간문맥 전이로 악성 폐쇄성 황달이 발생한 32명중 3000cGy이상의 방사선량이 조사된 23명을 대상으로 하였다. 치료 결과에 영향을 미칠 수 있는 요인을 알아보기 위하여 방사선량, 황달발생 당시의 질병의 진전정도 및 황달을 일으키는 종피의 위치, 방사선치료 전 총 bilirubin치, 다른 치료와의 병합여부, 원발병소의 수술정도, 재발전 병기를 분석하였다. 외부 방사선치료는 4백만 전자볼트 선형가속기를 이용하여 주 5회, 1회 180-300cGy를 간문맥을 포함하는 부위에 3000cGy-5480cGy(중앙값 3770cGy,TDF 49-86 3420cGy-5580cGy 중앙값 TDF 65, 4140cGy/23fx)가 조사되었다. TDF 65(4140cGy/23fx 이상과 미만을 받은 환자는 각각 13, 10명이었다. 결과 : 전체 환자 23명중 완전관해 13명, 부분관해 5명, 무반응 5명이었다. 전체 환자의 중앙 생존 기간은 5개월이나 완전관해의 경우는 11개월이고 부분관해와 무반응의 경우 각각 3개월이었다. 완전관해를 보인 13명중 6명이 1년 이상 생존하였다. 완전관해의 경우와 부분관해, 무반응과의 생존 기간의 비교에서 의미있는 차이를 보였다(p<0.05). TDF 65인 4140cGy 이상을 받은 13명중 완전관해, 부분관해, 무반응이 각각 10, 2, 1명이었다. 이들 전체환자의 중앙 생존 기간은 9.5개월 이었고 완전관해를 이룬경우 11.5개월 이었다. 그러나 TDF 65(4140cGy/23fx) 미만을 받은 10명중 완전관해, 부분관해, 무반응이 각각 3, 3, 4명 이었고 이들의 중앙 생존 기간은 4.3개월 이었다. 따라서 방사선량이 치료 결과에 영향을 미치며 완전관해를 이루기 위해서는 TOF 65(4140cGy/23fx)이상이 조사되어야 할 것이다. 치료시 질병의 진전정도는 완전관해를 보인 경우 7명이 간문맥이나 췌장 주위에만 국한된 병변을가졌고(5명 담도계하부 병변) 무반응과 부분반응을 보인 모든 환자는 광범위한 질병의 진전이 있거나, 일차병변의 지속상태였다. 질병의 진전상태가 국소적일수록, 담도계하부에 국한되어 있을수록 완전관해의 가능성이 높고 1년 이상 장기생존이 가능할 것으로 추정된다. 완전관해인 경우 10명이 방사선치료후 계속적인 항암화학요법을 받았고 이들중 6명이 1년 이상 생존하였다. 치료 결과에 영향을 미칠 것으로 추정되는 요인으로 방사선량, 황달 발생당시 질병의 진전정도 및 황달을 일으키는 종괴의 위치로 분석 되었다. 외부 방사선치료중 경미한 위장관 부작용(오심, 구토)이 발생하였으나 방사선치료 시행에 영향을 미치지 않았다. 결론 : 위암의 재발로 인해 발생한 악성 폐쇄성 황달환자의 치료에 있어서 TDF 65(4140cGy/23fx) 이상의 외부 방사선치료 단독으로도 만족할 만한 고식적 효과를 이룰수 있고 방사선량과 재발 당시 질병의 진전정도가 치료 결과에 영향을 미칠 수 있는 요인으로 생각 된다.

대장선암의 근본적인 치료는 외과적 절제술로 알려져 있으나 이 경우 직장선암과 마찬가지로 수술 후 국소재발이 문제시되어 왔다. 직장선암의 경우 수술 후 국소재발의 위험성이 볼은 판자에 수술후 방사선치료를 병용함으로써 국소제어율 및 나아가서 생존율까지도 상당히 개선된다고 알려져 있다. 그러나 대장선암의 경우 국소제어율 및 생존율의 개선이 보고되고 있기는 하나 아직 널리 알려져 있지는 못하다. 이에 저자는 1970년 3월부터 1984년 12월까지 대장선암으로 진단받고 일차적으로 근치적 수술을 시행한 후 연세대학교 의과대학 치료방사선과에 내원한 21명의 환자를 후향성 분석하여 다음과 같은 결과를 얻었다. 1. 21명의 환자 중 수술후 방사선 치료를 병용하여 계획대로 무사히 마친 환자는 11명이었다. 2. 수술후 방사선 치료를 병용한 환자들의 전체적 인 국소실패율은 $9\%(1/11)$이었고 병기별로는 B2+B3가(0/4), Cl+C2+C3가 $14\%(1/7)$였고 C1이 0(0/2) B2+C2가 $17\%(1/6)$, B3+C3가 0(0/3)였다. 3. 수술후 방사선 치료를 병용한 환자들의 5년 생존율은 $55\%$였다.

The clinical and pathological features of 35 cases of anaplastic thyroid cancer were studied. These tumors occurred in 12 men and 23 women ranging in age from 19 to 83 years(mean age; 61.7 years). A rapidly enlarging thyroid mass was the most common presentation. The duration of the presence of mass varied from 20 days to 12 months with an average of 2.7 months. Systemic metastasis at the time of initial examination was found in 14 patients(40.0%) and the lung was the most common site of involvement. The overall rate of distant metastasis was about 65.7%. The tumors were subdivided morphologically into giant cell type of 10 cases, spindle cell type of 7 cases, epidermoid cell type of 1 cases, and mixed giant cell and spindle cell type of 5 cases. The mean survival period of 6 among 35 patients who had biopsy alone was 1.4 months. The 22 patients underwent the incomplete combined treatment modalities (palliative surgery with or without chemotherpy or radiation therapy) survived for a mean period of 3.0 months, among them, 7 patients who had surgery combined with chemotherapy and radiation therapy showed mean survival period of 3.7 months. The mean survival of 7 patients who had complete combined treatment modality(curative surgery combined with chemotherapy and hyperfractionated radiation therapy) was 6.6 months, only one patient survived for 21 months and one patient has been alive for 1 month after operation, and the others survived for a mean period of 4.8 months. So far, as of July 31, 1998, 34 patients among 35 were died(one has been survived for 1 month) despite the various treatment modalities, and the main cause of death were failure of local control and systemic metastasis. None of the various treatment modalities gave consistently favourable results. However, a combination of surgery, radiation therapy and chemotherapy seemed to have a slight positive effect on survival. Furthermore, the aggressive treatment modalities will be indicated only in the early diagnosed and minimal cases.

Nasopharyngeal carcinoma(NPC) is a disease whose primary initial treatment is radiation. Results of radiation therapy in early stage disease is promising; however, in stage IV disease, the best reported five-year survival is only about 30%. In patients with post-radiation recurrent disease, radiation controls only a small portion of patients, as well as being associated with significant radiation injury. In this paper we discuss the use of salvage treatment modalities for post-radiation recurrence. A retrospective chart review and analysis of salvage treatment results were performed for 39 patients with recurrent post-radiation NPC and positive cervical lymph nodes during the period beginning 1985 until 1995. Mean age of these patients was 52.3$\pm$10.37 years and male: female ratio was 1.8 : 1. Twenty patients were treated with salvage treatment, and ten patients were treated by salvage chemotherapy. A total of nine patients underwent surgical salvage treatment, including neck dissection(6), transnasal laser surgery and booster radiotherapy(2), and primary surgery(1). Salvage treatment were effective in reducing patients' pain in twenty patients (51.3%) and prolonging life in nine patients(23.1%); however, recurrence of disease within six months and/or residual disease by clinical or radiologic exam was noted in all patients receiving salvage radiotherapy, chemotherapy, laser surgery with radiotherapy, and primary site surgery. In the group undergoing salvage neck dissection, three patients(50%) were disease free for at least two years. Of the different modalities, radiotherapy was associated with the best quality of life while catastrophic salvage surgery resulting in insignificant prolongation of life was associated with the poorest quality of life. We conclude that salvage surgery is the optimal choice of treatment for regional recurrence such as nodal failure, however palliative salvage therapy could be preferred in other cases with recurrent post-radiation NPC.

Malignant rhabdoid tumors arise primarily from the kidney. Extrarenal malignant rhabdoid tumors are rare, with the liver, central nervous system, and skin reported as the primary sites. Malignant rhabdoid tumors of the mediastinum are extremely rare among extrarenal malignant rhadoid tumors; only 3 cases have been reported to date, all characterized by aggressive clinical behavior. We experienced a 35-year-old woman diagnosed with malignant rhabdoid tumor in the anterior mediastinum with multiple metastases. The tumor was surgically unresectable, and treated with palliative radiation therapy. Three-month after radiation treatment, she died from dissemination of the malignant rabdoid tumor.

Background: The optimal sequence and extent of multimodality therapy remains to be defined for extrapulmonary small cell carcinoma because of its rarity. The purpose of our study was to assess the response to neoadjuvant chemotherapy followed by chemoradiation/radiation in patients with extrapulmonary small cell carcinoma. Materials and Methods: Four consecutively diagnosed patients were included in this study. The primary tumor site was oropharynx in three patients and esophagus in one. The patients with the limited disease were treated with chemotherapy followed by concurrent chemoradiation (n=2) or radiotherapy (n=1). The patient with the extensive disease with the primary site in vallecula was treated with chemotherapy and palliative radiotherapy to the metastatic site. Results: The median follow-up was 22.5 months (range, 8-24 months). Three patients with the limited disease (base of tongue, n=2; esophagus, n=1) were in complete remission. The patient with the extensive disease died of loco-regional tumor progression at 8 months from the time of diagnosis. Conclusions: The combination of chemotherapy and radiotherapy is the preferred therapeutic approach for patients with extrapulmonary small cell carcinoma. Induction chemotherapy followed by concurrent chemoradiation or radiation provides a good loco-regional control in patients with limited disease.
