Abstract PDF PubReader ePub: Purpose
The optimal short-course chemotherapeutic regimen for rectal cancer has not been clearly defined until now. KROG 10-01 and KROG 11-02 prospective trials investigated the efficacy and safety of 1- and 2-week chemoradiotherapy (CRT), respectively.
Materials and Methods
Patients eligible for KROG 10-01 and KROG 11-02 involved those with clinical T3-4N0-2M0 rectal cancers. They received preoperative CRT and total mesorectal excision. Patients in KROG 10-01 received radiation of 25 Gy in 5 fractions during 1 week with 5-fluorouracil/leucovorin. Patients in KROG 11-02 received radiation of 33 Gy in 10 fractions for 2 weeks with oral capecitabine.
Results
A total of 150 patients consisting of 70 patients from KROG 10-01 and 80 patients from KROG 11-02 were collectively analyzed. With a median follow-up time of 89.2 months, the 5-year overall survival rate was 86.5% in 1-week CRT and 85.3% in 2-week CRT (p=0.841). The 5-year recurrence-free survival rate was 83.5% in 1-week CRT and 77.1% in 2-week CRT (p=0.448). One patient (1.4%) in 1-week CRT and 11 patients (13.8%) in 2-week CRT exhibited pathologic complete regression (ypT0N0M0) after radiotherapy (p=0.006). One-week CRT had significantly higher acute hematologic (12.8% vs. 3.8%, p=0.040) and nonhematologic (38.6% vs. 16.3%, p=0.002) toxicity than 2-week CRT.
Conclusion
Both 1- and 2-week schedules of CRT showed favorable survival outcomes after 7 years of follow-up. But, 2-week course achieved more increased tumor response and decreased acute toxicity than 1-week course.

Effect of Waiting Time from Pathological Diagnosis to Definitive Concurrent Chemoradiation for Cervical Cancer on Overall Survival: Kyoung Won Noh, Bomi Kim, Chel Hun Choi, Tae-Joong Kim, Jeong-Won Lee, Byoung-Gie Kim, Duk-Soo Bae, Won Kyung Cho, Won Park, Yoo-Young Lee; Cancer Res Treat. 2022;54(1):245-252. Published online April 15, 2021; DOI: https://doi.org/10.4143/crt.2021.023

Abstract PDF Supplementary Material PubReader ePub

Purpose
This study aimed to evaluate the effect of waiting time, from diagnosis to initiation of definitive concurrent chemoradiation (CCRT), on overall survival in cervical cancer patients.
Materials and Methods
Patients with cervical cancer who were treated with definitive CCRT between 2000 and 2017 were retrospectively reviewed. Time from initial pathological diagnosis to definitive CCRT was analyzed both as a continuous variable (per day) and as a categorical variable in two groups (group 1 ≤ median, group 2 > median). Patients with a waiting time of more than 60 days were excluded.
Results
The median waiting time was 14 days (0-60). There were differences between group 1 and group 2 in age and chemotherapy regimens. However, no significant difference was found in the International Federation of Gynecology and Obstetrics stage, cell type, or the number of cycles of chemotherapy received during CCRT. A longer waiting time was associated with poorer overall survival on the Kaplan-Meier curve (group 1 vs. group 2, p=0.042). On multivariate analysis, intervals as either a continuous variable (hazard ratio [HR], 1.023; 95% confidence interval [CI], 1.006 to 1.040; p=0.007) or a categorical variable (HR, 1.513; 95% CI, 1.073 to 2.134; p=0.018), FIGO stage, cell type, and the number of cycles of chemotherapy received during CCRT were significant independent prognostic factors for overall survival.
Conclusion
A shorter waiting time from pathological diagnosis to definitive CCRT showed benefit on overall survival. Our findings suggest that an effort to minimize waiting times should be recommended in cervical cancer patients who are candidates for CCRT.

Carcinoembryonic Antigen Improves the Performance of Magnetic Resonance Imaging in the Prediction of Pathologic Response after Neoadjuvant Chemoradiation for Patients with Rectal Cancer: Gyu Sang Yoo, Hee Chul Park, Jeong Il Yu, Doo Ho Choi, Won Kyung Cho, Young Suk Park, Joon Oh Park, Ho Yeong Lim, Won Ki Kang, Woo Yong Lee, Hee Cheol Kim, Seong Hyeon Yun, Yong Beom Cho, Yoon Ah Park, Kyoung Doo Song, Seok-Hyung Kim, Sang Yun Ha; Cancer Res Treat. 2020;52(2):446-454.

Abstract PDF Supplementary Material PubReader ePub

Purpose
The purpose of this study was to investigate the role of carcinoembryonic antigen (CEA) levels in improving the performance of magnetic resonance imaging (MRI) for the prediction of pathologic response after the neoadjuvant chemoradiation (NCRT) for patients with rectal cancer.
Materials and Methods
We retrospectively reviewed the medical records of 524 rectal cancer patients who underwent NCRT and total mesorectal excision between January 2009 and December 2014. The performances of MRI with or without CEA parameters (initial CEA and CEA dynamics) for prediction of pathologic tumor response grade (pTRG) were compared by receiver-operating characteristic analysis with DeLong’s method. Cox regression was used to identify the independent factors associated to pTRG and disease-free survival (DFS) after NCRT.
Results
The median follow-up was 64.0 months (range, 3.0 to 113.0 months). On multivariate analysis, poor tumor regression grade on MRI (mrTRG; p < 0.001), initial CEA (p < 0.001) and the mesorectal fascia involvement on MRI before NCRT (mrMFI; p=0.054) showed association with poor pTRG. The mrTRG plus CEA parameters showed significantly improved performances in the prediction of pTRG than mrTRG alone. All of mrTRG, mrMFI, and initial CEA were also identified as independent factors associated with DFS. The initial CEA further discriminated DFS in the subgroups with good mrTRG or that without mrMFI.
Conclusion
The CEA parameters significantly improved the performance of MRI in the prediction of pTRG after NCRT for patients with rectal cancer. The DFS was further discriminated by initial CEA level in the groups with favorable MRI parameters.

Impact of Chemoradiation on Prognosis in Stage IVB Cervical Cancer with Distant Lymphatic Metastasis: Hee Seung Kim, Taehun Kim, Eung Seok Lee, Hak Jae Kim, Hyun Hoon Chung, Jae Weon Kim, Yong Sang Song, Noh Hyun Park; Cancer Res Treat. 2013;45(3):193-201. Published online September 30, 2013; DOI: https://doi.org/10.4143/crt.2013.45.3.193

Abstract PDF PubReader ePub

PURPOSE
The purpose of this study was to determine whether chemoradiation (CCR) is efficient for improving prognosis, compared with systemic chemotherapy (SC), in patients with stage IVB cervical cancer who have distant lymphatic metastasis.
MATERIALS AND METHODS
Among 2,322 patients with cervical cancer between January 2000 and March 2010, 43 patients (1.9%) had stage IVB disease. After exclusion of 19 patients due to insufficient data and hematogenous metastasis, 24 patients (1%) who received CCR (n=10) or SC (n=14) were enrolled. We compared tumor response, progression-free survival (PFS) and overall survival (OS), and disease recurrence between CCR and SC.
RESULTS
Complete response rates were 60% and 0% after CCR and SC (p<0.01). Grade 3 or 4 leukopenia was more common in patients treated with CCR (24.4% vs. 9.1%, p=0.03), whereas grade 3 or 4 neuropenia was more frequent in those treated with SC (28.4% vs. 11.1%, p=0.03). Development of grade 3 proctitis occurred as a late radiotherapy (RT)-related toxicity in only one patient (10%) treated with CCR. In addition, squamous cell carcinoma and CCR were favorable prognostic factors for improvement of PFS (adjusted hazard ratios [HRs], 0.17 and 0.12; 95% confidence intervals [CIs], 0.04 to 0.80 and 0.03 to 0.61), and only CCR was significant for improvement of OS (adjusted HR, 0.15; 95% CI, 0.02 to 0.90). However, no differences in the rate and pattern of disease recurrence were observed between CCR and SC.
CONCLUSION
CCR may be more effective than SC for improving survival, and can be regarded as a feasible method with some caution regarding late RT-related toxicity for treatment of stage IVB cervical cancer with distant lymphatic metastasis.

PURPOSE
To evaluate treatment outcomes and prognostic factors in non-small cell lung cancer (NSCLC) patients treated with concurrent chemoradiation.
MATERIALS AND METHODS
From January 2005 to June 2009, 51 patients were treated with concurrent chemoradiation for 3 different aims: locally advanced stage III, locally recurrent disease, and postoperative gross residual NSCLC. Median age was 63 years. Distribution of stages by the 6th edition of American Joint Committee on Cancer (AJCC) was as follows: IIIA (37.3%), IIIB (56.9%). Chemotherapy was administered every week concurrently with radiation using one of the following regimens: paclitaxel (60 mg/m2), docetaxel+cisplatin (20 mg/m2+20 mg/m2), cisplatin (30 mg/m2). Total radiation dose was 16-66.4 Gy (median, 59.4 Gy).
RESULTS
Median follow-up duration was 40.8 months. The overall response rate was 84.3% with 23 complete responses. The median survival duration for the overall patient group was 17.6 months. The 3-year survival rate was 17.8%. A total of 21 patients had recurrent disease at the following sites: loco-regional sites (23.6%), distant organs (27.5%). In the multivariate analysis of the overall patient group, a clinical tumor response (p=0.002) was the only significant prognostic factor for overall survival (OS). In the multivariate analysis of the definitive chemoradiation arm, the use of consolidation chemotherapy (p=0.022), biologically equivalent dose (BED)10 (p=0.007), and a clinical tumor response (p=0.030) were the significant prognostic factors for OS.The median survival duration of the locally recurrent group and the postoperative gross residual group were 26.4 and 23.9 months, respectively.
CONCLUSION
Our study demonstrated that clinical tumor response was significantly associated with OS in the overall patient group. Further investigations regarding the optimal radiation dose in the definitive chemoradiation and the optimal treatment scheme in locally recurrent NSCLC would be required.

Purpose

The combination of chemoradiation and fluorouracil based chemotherapy has been the standard adjuvant treatment for colorectal cancer patients. The aim of this study was to evaluate treatment outcome of patients classified by the new AJCC staging system and to compare treatment outcome of oral doxifluridine and the standard Mayo Clinic regimen after chemoradiation in advanced rectal cancer patients.

Materials and Methods

One hundred nine patients underwent curative surgical resection and chemoradiation followed by chemotherapy. 45 Gy pelvic irradiation was given to the entire pelvis and the boost radiation with 50.4 to 54 Gy, and simultaneously 5-fluorouracil (5-FU) 375 mg/m²/day was given on day 1~3 and 26~28. After the completion of chemoradiation, patients were given either 6 cycles of the Mayo Clinic regimen (5-FU 425 mg/m² plus leucovorin 20 mg/m² intravenous bolus infusion on day 1~5, every 4 weeks) or oral doxifluridine (600 mg/m²/day) for 1 year.

Results

The median follow-up duration was 30 months. Among 102 evaluable patients, 38 patients (37.3%) relapsed: the locoregional recurrence in 10 patients (9.8%) and systemic relapse in 28 patients (27.5%). The systemic relapse rate was 15.6% in the stage IIA, 25.0% in the stage IIIB , and 59.1% in the stage IIIC (p=0.048). The 5-year disease-free survival (DFS) rate was significantly higher in the IIA and IIIA patients than the IIIB and IIIC patients (72% and 100% vs 48.1% and 11.2%, respectively. p<0.001). The 5-year overall survival (OS) rate was also significantly different between in the IIA/IIIA patients and the IIIB/IIIC (67.3%/100% vs 48.4%/22.3%. p<0.001). However, the difference in DFS or OS between the oral doxifluridine group and the Mayo Clinic regimen group was not significant. Cox regression multivariate analyses showed that the new AJCC stage and tumor differentiation were significant independent prognostic factors in DFS and OS.

Conclusion

These results support that the new AJCC staging system is superior to Dukes' staging system in the prognostic stratification. Regarding DFS and OS, oral doxifluridine is comparable to the standard Mayo Clinic regimen in rectal cancer patients when combined with postoperative chemoradiation. Stage IIIC patients should be selected for aggressive therapy as they have a dismal prognosis.

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.

Abstract PDF: PURPOSE
To assess the tumor response, sphincter preservation, acute toxicity and survival with preoperative concurrent chemoradiation in locally advanced rectal cancer.
MATERIALS AND METHODS
Fifty-four patients were treated with preoperative chemoradiaton for tumor downstaging and sphincter preservation. Radiation was delivered to whole pelvis to 45 Gy followed by a boost 5.4 Gy to primary tumor site. Chemotherapy consists of concurrent 2 cycles of 5-fluorouracil (500 mg/m2/day) and leucovorin (20 mg/m2/day). Surgery was performed approximately 6 weeks after treatment.
RESULTS
Median follow-up period and rate were 48 months and 98%, respectively. The downstaging including primary tumor and lymph node occurred in 64%. Three of 53 patients (6%) had pathologic complete response. The resectability of tumor was 98%. A sphincter preservation was possible in 61%. Three patients developed grade 4 hematologic toxicity. Grade 3 skin erythema and diarrhea were 24% and 18%, respectively. The 5-year survival and local disease-free survival were 62% and 89%, respectively. Local failure and distant metastasis rate were 9% and 35%, respectively.
CONCLUSION
Preoperative chemoradiation affords considerable downstaging with acceptable acute toxicity and postoperative morbidity. Also sphincter preservation is feasible by improved downstaging of tumor. This treatment could be improved local control of tumor, and may have a potential for long-term survival.

Concurrent Chemoradiation Therapy with Cisplatin and Oral Etoposide for Locally Advanced Non-small Cell Lung Cancer: Chang Won Paek, So Young Yoon, Jae Hong Seo, Chul Won Choi, Byung Soo Kim, Sang Won Shin, Yeul Hong Kim, Jae Jung Shim, Kyung Ho Kang, Jun Suk Kim, Chul Yong Kim, Myung Sun Choi, Young Ho Choi, Kwang Tak Kim; J Korean Cancer Assoc. 2000;32(4):682-689.

Abstract PDF: PURPOSE
Prognosis of locally advanced inoperable non-small cell lung cancer (NSCLC) treated with radiation therapy alone has been disappointing. In recent years, concurrent chemoradiation therapy has potential of improving both local and metastatic disease-free survival. This phase II study was undertaken to determine the feasibility, toxicity, response rate, local control rate, and survival duration of locally advanced NSCL patients treated with concurrent chemoradiation using cisplatin and oral etoposide. MATERIAL AND METHODS: Forty-seven patients were enrolled and forty-one patients were evaluable. Chemotheray consisted of cisplatin 50 mg/m2/IV on days 1 and 8 and oral etoposide 100 mg/day on days 1 to 5 and 8 to 12 which was repeated, every 4 weeks for two cycles during radiation therapy. Radiation therapy was administered to a total dose of 6300 cGY.
RESULTS
Among 41 evaluable patients, six patients achieved complete response, and twenty had partial response, for an overall response rate of 63.4% (95% confidence interval; 48.4% to 75.4%). Stable disease was reported in 10 patients (24.4%) and another 5 (12.2%) showed disease pro gression. Overall survival rate was 76% at 1 year, 34% at 2 years. Median survival duration was 17 months (range; 3 to 41 ). Eighty-three percents of patients had radiation pneumonitis but only one patients needed medical treatment.
CONCLUSION
Concurrent chemoradiation therapy with cisplatin and oral etoposide at this level is a well tolerated and feasible.
