Abstract PDF Supplementary Material PubReader ePub: Purpose
A “Smart Cancer Care” platform that integrates patient-reported outcomes (PROs) with management has been established in Korea. This study focused on improving health behaviors and connecting patients to welfare services by introducing and assessing the feasibility of “Smart Cancer Care 2.0,” an enhanced version designed for monitoring complications post-cancer treatment.
Materials and Methods
Smart Cancer Care 2.0 was developed by conducting a literature review and consulting with expert panels to identify symptoms or variables requiring monitoring and management guidelines based on the treatment type. Qualitative and quantitative surveys were conducted to assess the feasibility of the app and web system based on the experiences of patients with cancer and healthcare workers.
Results
A total of 81 symptoms or variables (chemotherapy-, surgery-, radiotherapy-, rehabilitation-, and health management-related) were selected for management in Smart Cancer Care 2.0. PROs for these symptoms were basically categorized into three severity grades: preventive management, self-treatment, and consultation with a healthcare worker or visit to a healthcare institution. The overall mean scores in the feasibility evaluation by patients and healthcare workers were 3.83 and 3.90 points, respectively, indicating high usefulness.
Conclusion
Smart Cancer Care 2.0 leverages the existing information and communication technologies–based platform, Smart Cancer Care, and further includes health behaviors and welfare services. Smart Cancer Care 2.0 may play a crucial role in establishing a comprehensive post-discharge management system for patients with cancer as it provides suitable interventions based on patients’ responses and allows the regularly collected PROs to be easily viewed for streamlined care.

Purpose

Capecitabine is an oral fluoropyrimidine carbamate and it is known as an effective radiosensitizer. Capecitabine and its metabolite reach their peak concentration in the plasma at 1~2 hours after a single oral administration of capecitabine and the levels fall rapidly thereafter. To verify the radiosensitizing effect of capecitabine that is based on such pharmacokinetic characteristics, we performed a retrospective analysis on the optimal timing of capecitabine administration with performing preoperative chemoradiation for locally advanced rectal cancer.

Materials and Methods

Among 171 patients who were treated with preoperative radiotherapy and concurrent capecitabine administration for rectal cancer, 56 patients were administered capecitabine at 1~2 hours before radiotherapy (group A), and at other time in the other 115 patients (group B). Total mesorectal excision was done at 4 to 6 weeks after the completion of chemoradiation. The radiosensitizing effect of capecitabine was evaluated on the basis of the pathological response.

Results

Complete pathological regression of the primary tumor was observed in 12 patients (21.4%) for group A and in 11 patients (9.6%) for group B (p=0.031). Residual disease less than 0.5 cm (a good response) was observed in 19 patients (33.9%) for group A and in 23 patients (20.0%) for group B (p=0.038). On multivariate analysis, the capecitabine ingestion time showed marginal significance.

Conclusion

When performing preoperative chemoradiation for locally advanced rectal cancer, the radiosensitizing effect of capecitabine was enhanced when it was administered 1 hour before radiotherapy.

Ependymoma: a Retrospective Analysis of 25 Cases: Young Seok Kim, Seung Do Ahn, Eun Kyung Choi, Jong Hoon Kim, Sang Wook Lee, Young Ju Noh, Chang Jin Kim, Jeong Hoon Kim, Byung Duk Kwun; Cancer Res Treat. 2002;34(6):450-456.

Abstract PDF

PURPOSE
We evaluated the patterns of failure, survival rate, prognostic factors and treatment related complication in postoperative radiation treatment of patients with ependymoma.
MATERIALS AND METHODS
We retrospectively analyzed 25 patients with histologically confirmed ependymoma treated between Jun. 1990 and Jun. 2001 with postoperative radiotherapy at Asan Medical Center. The study group comprised of 16 men and 9 women, with a median age of 23 years; including 6 supratentorial, 15 infratentorial and 4 spinal cord lesions. The extents of resection were ranked as either: gross total, near total, subtotal, partial resection or biopsy, with these types of surgical resection being performed in 13, 3, 6, 1 and 2 patients, respectively. Twelve of the patients had low grade ependymoma, and the other 13 a high grade tumor. The postoperative irradiation was administered using 4 MV or 6 MV photons, up to median dose of 55.0 Gy (range, 45.0~59.4 Gy), with the radiation field encompassing the preoperative tumor volume plus a 2 cm margin. Only 8 of the patients received either pre- or postoperative chemotherapy. The median follow-up period of survivors was 43 months.
RESULTS
Ten of the 25 patients (40%) developed a recurrence, and 5 died. Of the 10 recurred patients, 6 showed an in-field recurrence, and one developed both an in-field and an out of field recurrence. The remaining 3 patients showed an out of field recurrence, including one case with a leptomeningeal recurrence. The 5-year overall survival, and progression-free, survival rates were 74.0 and 56.1%, respectively. The histological grades were statistically significant prognostic factors of the overall and progression-free survival rates. There were no significant treatment related complications, with the exception of one case of panhypopituitarism, which occurred 30 months after completion of the radiotherapy.
CONCLUSION
The main pattern of recurrence was due to local failure. In order to improve the local control, and to reduce complications, advanced radiation treatment techniques, such as 3 dimensional radiotherapy, may be needed.

Abstract PDF

PURPOSE
To investigate the feasibility, toxicity and response rate, of concurrent chemoradiation therapy with paclitaxel/cisplatin in stage III locally advanced non-small cell lung cancer (NSCLC).
MATERIALS AND METHODS
Between May 1999 and December 2000, 80 patients with stage III NSCLC were enrolled in a prospective protocol. Radiotherapy was given to a total dose of 70.2 Gy (daily fraction of 1.8 Gy for 5 days), over an 8 week period, on the gross tumor volume, combined with chemotherapy. The concurrent chemotherapy consisted of paclitaxel (40 mg/m2) and 20 mg/m2 cisplatin per week for 8 consecutive weeks. All patients received 3-D conformal radiotherapy using CT-simulated planning. Acute toxicities were evaluated by the RTOG scale. The median follow-up period was 16 months, ranging from 3 to 29 months.
RESULTS
Of the 80 patients, 71 received treatment per protocol, with minor variation of protocol delivery. The median age of the patients was 60 years. Karnofsky Performance status were 100 and 90 in 62 patients, and 80 and 70 in 9, respectively. Weight loss of less than 5% for 6 months was observed in 22 patients. The response to treatment was evaluated from the radiological findings. Complete and partial responses were observed in 8 and 51 patients, respectively. Ultimately, 82% of patients (included complete responses: 8 cases) obtained more than a partial response. Although, radiation induced esophagitis was the most common treatment related toxicity, occurring in 44 patients (69%), severe radiation esophagitis like, grade 3, was observed in only 3 patients, and the most acute toxicities had completely recovered 1 month following treatment. The overall 2-year actuarial and progression free survivals were 56 and 45%, respectively.
CONCLUSION
This combined modality has activity with manageable toxicity and 23 months in mean survival time in patients with stage III NSCLC. A longer follow up will be required to realise the expected higher survival of these results.
