1.Radiotherapy in Elderly Patients with Cancer.
The Journal of the Korean Society for Therapeutic Radiology and Oncology 2011;29(1):1-10
Due to improved life spans, cancer incidence has increased with more aged patients presenting with cancer. Elderly cancer patients could have compromised organ function and/or comorbidities. Due to poor social support or lack of early diagnosis, treatment outcomes for elderly cancer patients are poor in general. However, with aggressive support during cancer management as well as careful selection, most elderly cancer patients can tolerate standard radiation therapy with good results based on published articles. Here, we reviewed existing articles regarding compliance and treatment results in elderly cancer patients based on tumor site.

A clear consensus has not been established regarding the best treatment for solitary bone metastasis. Here, we reviewed the medical records of patients with a controlled primary malignancy who had only solitary spine metastasis without metastasis to the extraspinal bone or viscera and underwent treatment between April 2007 and December 2012 with stereotactic body radiosurgery using CyberKnife, with a total dose of 24 Gy in three to four fractions. During that time, there were only four cases. This was effective in each case, and all the four patients had no local failure and remained alive at a median follow-up of 68 months (range, 64 to 80 months). Although our experience is limited, this study suggests that stereotactic body radiotherapy could be a feasible, safe, effective, and noninvasive alternative treatment for solitary spine metastasis in patients who are medically inoperable or unsuitable for surgery.

3.Integrative Medicine for Cancer Patients.
Hanyang Medical Reviews 2010;30(2):126-135
Majority of cancer patients used CAM modalities during and even after cancer treatment. Main reasons for CAM use are to improve immunity, with expectation of fewer recurrences, and to have better quality of life. Still many patients did not reveal precise detailed information of CAM use to their physicians. Due to possible interaction between herbs and cancer drugs, it is essential for physicians to know whether their patients use CAM modalities or not and to have interest in existing evidence. This article will provide the lists of evidence and references on supplements and life styles including diet and exercise. Mind body medicine is not commonly used in Korea but there is increasing evidence on meditation and usefulness with relaxation even in supportive care.

5.Management for locally advanced cervical cancer: new trends and controversial issues
Radiation Oncology Journal 2018;36(4):254-264
This article reviewed new trends and controversial issues, including the intensification of chemotherapy and recent brachytherapy (BT) advances, and also reviewed recent consensuses from different societies on the management of locally advanced cervical cancer (LACC). Intensive chemotherapy during and after radiation therapy (RT) was not recommended as a standard treatment due to severe toxicities reported by several studies. The use of positron emission tomography-computed tomography (PET-CT) and magnetic resonance imaging (MRI) for pelvic RT planning has increased the clinical utilization of intensity-modulated radiation therapy (IMRT) for the evaluation of pelvic lymph node metastasis and pelvic bone marrow. Recent RT techniques for LACC patients mainly aim to minimize toxicities by sparing the normal bladder and rectum tissues and shortening the overall treatment time by administering a simultaneous integrated boost for metastatic pelvic lymph node in pelvic IMRT followed by MRI-based image guided adaptive BT.

PURPOSE: To evaluate the treatment results and prognostic factors after radiotherapy in stage IIB uterine cervix cancer. MATERIALS AND METHODS: We retrospectively analyzed the records of 90 patients with stage IIB uterine cervix cancer who received radiotherapy between 9/94 and 12/99. Age was ranged from 28 to 79 years (median 57). Tumor size was > or = 4 cm in 64 patients. Preteatment SCC level was measured in 76 patients. Twenty nine patients received conventional radiotherapy (QD) and the others received modified hyperfractionated radiotherapy (BID). Only 7 patients in BID had tumor size <4 cm. All patients received high dose rate brachytherapy (4 Gy x 7 or 5 Gy x 6). No patient received concurrent chemotherapy during radiotherapy. Follow up period was ranging from 9 to 76 months (median 38). RESULTS: The 5-year overall and disease free survival rates were 73.4% and 71.6%, respectively. Local recurrences occurred in 10% of patients, and distant metastasis in 18.9%. There was a significant correlation between OS/DFS and tumor size (<4 cm; OS 95.2%, DFS 91.4%, > or = 4 cm; OS 63.4%, DFS 63.4%). Pretreatment SCC level was one of prognostic factors only in univariate analysis. CONCLUSION: With modified hyperfractionated radiotherapy, there was very low local recurrence rate (6.6%) and high 5-year overall and disease free survival rate (75.4% and 70.5%), which is comparable to results after concurrent chemoradiotherapy in bulky, locally advanced stage IIB uterine cervix cancer.

Radiation therapy is an effective modality to alleviate cancer-related symptoms. To deliver radiation accurately, it is essential to secure stability of the treatment position in patients during each treatment time. However, some patients could be less cooperative due to their psychoemotional issues. We present two cases of terminal-stage cancer patients who were initially unable to lie still on the treatment table before simulation. A relaxation technique was taught to them on the bed, and they could relax and undergo radiation therapy with effective symptom relief.

PURPOSE: The degree of radiation-induced lung fibrosis (RILF) can be measured quantitatively by fibrosis volume (VF) on chest computed tomography (CT) scan. The purpose of this study was to investigate the interobserver and intraobserver variability in CT-based measurement of VF. MATERIALS AND METHODS: We selected 10 non-small cell lung cancer patients developed with RILF after postoperative radiation therapy (PORT) and delineated VF on the follow-up chest CT scanned at more than 6 months after radiotherapy. Three radiation oncologists independently delineated VF to investigate the interobserver variability. Three times of delineation of VF was performed by two radiation oncologists for the analysis of intraobserver variability. We analysed the concordance index (CI) and inter/intraclass correlation coefficient (ICC). RESULTS: The median CI was 0.61 (range, 0.44 to 0.68) for interobserver variability and the median CIs for intraobserver variability were 0.69 (range, 0.65 to 0.79) and 0.61(range, 0.55 to 0.65) by two observers. The ICC for interobserver variability was 0.974 (p < 0.001) and ICCs for intraobserver variability were 0.996 (p < 0.001) and 0.991 (p < 0.001), respectively. CONCLUSION: CT-based measurement of VF with patients who received PORT was a highly consistent and reproducible quantitative method between and within observers.

PURPOSE: It is not a simple task to achieve the ideal isodose curve with a standard vaginal applicator or single plane needle impant in the paravaginal tissue when primary or recurrent gynecological neoplasms (cervical cancers, vaginal cancers and vulvar cancers) are treated as a boost following external beam radiotherapy. The authors introduce the development and construction of a simple, inexpensive, customized applicator for volume implant to maximize the radiation dose to the tumor while minimizing the dose to the rectum and the bladder. MATERIALS AND METHODS: Nine patients underwent Ir-192 transperineal interstitial implantation for either recurrent (5 cases) or primary (3 cases) cervical cancers or primary vaginal cancer (1 case) between August 1994 and February 1998 at Ajou university hospital. First 3 cases were performed with a single plane implant guided by digital palpation. Because of inadequate isodose coverage in the tumor volume in first 3 cases, we designed and constructed interstitial vaginal applicator for volume implant to improve tumor dose distribution and homogeneity while sparing the surrounding normal tissue. Our applicators consist of vaginal obturator and perineal template that made of the clear acrylamide and dental mold material (Provil ). The applicators were customized individually according to the tumor size and its location. Both HDR and LDR irradiation were given with these applicators accomodating 6 Fr needles (Microselectron, Nucletron). The pretreatment planning prior to actual implant was performed whenever possible. RESULTS: Needles can be inserted easily and evenly into the tumor volume through the holes of templates, requiring less efforts and time for the implant prodecure. Our applicators made of materials available from commercial vendors. These have an advantage that require easy procedure, and spend relatively short time to construct. Also it was possible to fabricate applicators to individualize according to the tumor size and its location and to achieve the ideal isodose coverage. We found an accurate needle arrangement and ideal dose distribution through the CT scan that was obtained in 3 cases after needle implant. Three patients with primary cervical and vaginal cancers were controlled locally at final follow up. But all recurrent cases failed to do so. CONCLUSION: The authors introduce inexpensive, simple interstitial vaginal templates which were self-designed and constructed using materials available from commercial vendors such as acrylamide and dental mold material (Provil ).
