Combined High-Dose Radiotherapy with Sequential Gemcitabine-Cisplatin Based Chemotherapy Increase the Resectability and Survival in Locally Advanced Unresectable Intrahepatic Cholangiocarcinoma: A Multi-institutional Cohort Study: Jung Ho Im, Jeong Il Yu, Tae Hyun Kim, Tae Gyu Kim, Jun Won Kim, Jinsil Seong; Cancer Res Treat. 2024;56(3):838-846. Published online January 2, 2024; DOI: https://doi.org/10.4143/crt.2023.886

Abstract PDF Supplementary Material PubReader ePub: Purpose
The locally advanced unresectable intrahepatic cholangiocarcinoma (ICC) has detrimental oncological outcomes. In this study, we aimed to investigate the efficacy of radiotherapy in patients with locally advanced unresectable ICC.
Materials and Methods
Between 2001 and 2021, 116 patients were identified through medical record who underwent radiotherapy for locally advanced unresectable ICC. The resectability of ICC is determined by the multidisciplinary team at each institution. Overall survival (OS) were analyzed using the Kaplan-Meier method, and prognostic factors were analyzed using the Cox proportional hazards model.
Results
The median equivalent radiotherapy dose in 2 Gy fractions (EQD2) was 52 Gy (range, 30 to 110 Gy). Forty-seven patients (40.5%) received sequential gemcitabine-cisplatin based chemotherapy (GEM-CIS CTx). Multivariate analysis identified two risk factors, EQD2 of ≥ 60 Gy and application of sequential GEM-CIS CTx for OS. Patients were grouped by these two risk factors: group 1, EQD2 ≥ 60 Gy with sequential GEM-CIS CTx (n=25); group 2, EQD2 < 60 Gy with sequential GEM-CIS CTx or fluoropyrimidine-based concurrent chemoradiotherapy (n=70); and group 3, radiotherapy alone (n=21). Curative resection was more frequently undergone in group 1 than in groups 2 or 3 (28% vs. 8.6% vs. 0%, respectively). Consequently, OS was significantly better in group 1 than in groups 2 and 3 (p < 0.05).
Conclusion
Combined high-dose radiotherapy with sequential GEM-CIS CTx improved oncologic outcomes in patients with locally advanced unresectable ICC. Further prospective studies are required to validate these findings.

Neoadjuvant Chemotherapy–Guided Bladder-Sparing Treatment for Muscle-Invasive Bladder Cancer: Results of a Pilot Phase II Study: Hongzhe Shi, Wen Zhang, Xingang Bi, Dong Wang, Zejun Xiao, Youyan Guan, Kaopeng Guan, Jun Tian, Hongsong Bai, Linjun Hu, Chuanzhen Cao, Weixing Jiang, Zhilong Hu, Jin Zhang, Yan Chen, Shan Zheng, Xiaoli Feng, Changling Li, Yexiong Li, Jianhui Ma, Yueping Liu, Aiping Zhou, Jianzhong Shou; Cancer Res Treat. 2021;53(4):1156-1165. Published online February 10, 2021; DOI: https://doi.org/10.4143/crt.2020.1356

Abstract PDF Supplementary Material PubReader ePub

Purpose
Reduced quality of life after cystectomy has made bladder preservation a popular research topic for muscle-invasive bladder cancer (MIBC). Previous research has indicated significant tumor downstaging after neoadjuvant chemotherapy (NAC). However, maximal transurethral resection of bladder tumor (TURBT) was performed before NAC to define the pathology, impacting the real evaluation of NAC. This research aimed to assess real NAC efficacy without interference from TURBT and apply combined modality therapies guided by NAC efficacy.
Materials and Methods
Patients with cT2-4aN0M0 MIBC were confirmed by cystoscopic biopsy and imaging. NAC efficacy was assessed by imaging, urine cytology, and cystoscopy with multidisciplinary team discussion. Definite responders (≤ T1) underwent TURBT plus concurrent chemoradiotherapy. Incomplete responders underwent radical cystectomy or partial cystectomy if feasible. The primary endpoint was the bladder preservation rate.
Results
Fifty-nine patients were enrolled, and the median age was 63 years. Patients with cT3-4 accounted for 75%. The median number of NAC cycles was three. Definite responders were 52.5%. The complete response (CR) was 10.2%, and 59.3% of patients received bladder-sparing treatments. With a median follow-up of 44.6 months, the 3-year overall survival (OS) was 72.8%. Three-year OS and relapse-free survival were 88.4% and 60.0% in the bladder-sparing group but only 74.3% and 37.5% in the cystectomy group. The evaluations of preserved bladder function were satisfactory.
Conclusion
After stratifying MIBC patients by NAC efficacy, definite responders achieved a satisfactory bladder-sparing rate, prognosis, and bladder function. The CR rate reflected the real NAC efficacy for MIBC. This therapy is worth verifying through multicenter research.

Purpose
We aimed to assess prognostic value of metastatic pelvic lymph node (mPLN) in early-stage cervical cancer treated with radical surgery followed by postoperative chemoradiotherapy. Also, we sought to define a high-risk group using prognosticators for recurrence.
Materials and Methods
A multicenter retrospective study was conducted using the data from 13 Korean institutions from 2000 to 2010. A total of 249 IB-IIA patients with high-risk factors were included. We evaluated distant metastasis-free survival (DMFS) and disease-free survival (DFS) in relation to clinicopathologic factors including pNstage, number of mPLN, lymph node (LN)ratio (number of positive LN/number of harvested LN), and log odds of mPLNs (log(number of positive LN+0.5/number of negative LN+0.5)).
Results
In univariate analysis, histology (squamous cell carcinoma [SqCC] vs. others), lymphovascular invasion (LVI), number of mPLNs (≤ 3 vs. > 3), LN ratio (≤ 17% vs. > 17%), and log odds of mPLNs (≤ ‒0.58 vs. > ‒0.58) were significant prognosticators for DMFS and DFS. Resection margin involvement only affected DFS. No significant survival difference was observed between pN0 patients and patients with 1-3 mPLNs. Multivariate analysis revealed that mPLN > 3, LVI, and non-SqCC were unfavorable index for both DMFS (p < 0.001, p=0.020, and p=0.031, respectively) and DFS (p < 0.001, p=0.017, and p=0.001, respectively). A scoring system using these three factors predicts risk of recurrence with relatively high concordance index (DMFS, 0.69; DFS, 0.71).
Conclusion
mPLN > 3 in early-stage cervical cancer affects DMFS and DFS. A scoring system using mPLNs > 3, LVI, and non-SqCC could stratify risk groups of recurrence in surgically resected early-stage cervix cancer with high-risk factors.

Personalized Combined Modality Therapy for Locally Advanced Non-small Cell Lung Cancer: D. Nathan Kim, Taek-Keun Nam, Kevin S. Choe, Hak Choy; Cancer Res Treat. 2012;44(2):74-84. Published online June 30, 2012; DOI: https://doi.org/10.4143/crt.2012.44.2.74

Abstract PDF PubReader ePub

Locally advanced non-small cell lung cancer (NSCLC) is a heterogeneous disease, and we have embarked on an era where patients will benefit from individualized therapeutic strategies based on identifiable molecular characteristics of the tumor. The landmark studies demonstrating the importance of molecular characterization of tumors for NSCLC patients, the promising molecular pathways, and the potential molecular targets/agents for treatment of this disease will be reviewed. Understanding these issues will aid in the development of rationally designed clinical trials, so as to determine best means of appropriately incorporating these molecular strategies, to the current standard of radiation and chemotherapy regimens, for the treatment of locally advanced NSCLC.

Abstract PDF PubReader ePub

Coombs' negative autoimmune hemolytic anemia (AIHA) is a rare disease which shares similar clinical and hematological features with Coombs' positive AIHA, but its exact frequency remains unknown. There have been few reports of idiopathic thrombocytopenic purpura (ITP) and Coombs' negative AIHA associated with other lymphoproliferative disorders (LPDs). Since there is a well known association between LPDs and autoimmune phenomena, it is important to investigate the possibility of an underlying malignancy. We report a case of ITP and Coombs' negative AIHA associated with diffuse large B-cell lymphoma.

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.

Combination Chemotherapy with 5-Fluorouracil and Carboplatin for Advanced Head and Neck Cancer: Eun Kyung Cho, Won Sup Lee, Chul Won Jung, Keun Seok Lee, Won Seog Kim, Ki Hyeong Lee, Dae Seog Heo, Yung Jue Bang, Kwang Hyun Kim, Charn II Park, Noe Kyeong Kim; J Korean Cancer Assoc. 1996;28(1):94-104.

Abstract PDF: Twenty-nine patients with previously untreated, locally advanced head and neck cancer were treated with two or three cycles of combination chemotherapy consisting of 5- fluorouracil infusion and carboplatin, followed by surgery and/or curative radiotherapy. Nine patients with recurrent head and neck cancer were treated with the same combination chemotherapy. The results were as follows; 1) Among 28 evaluable patients, response rate was 71.4%(partial response) after neoadjuvant chemotherapy. Following local modality(surgery and/or radiotherapy), response rate was 79%(complete response 51.4%, and partial response 25%). 2) One year survival rate in neoadjuvant group was 83% and one year progression-free survival rate, 68.8%. The progression-free survival of responders was significantly prolonged in comparison with that of non-responders(p<0.05). 3) In palliative treatment group, one partial response(11%) was observed among nine patients. Median time to progression was 6.8 weeks and median survival was 17.7 weeks; there was no significant difference between responders and non-responders. 4) Nausea and vomiting were frequently observed but easily controlled. Hematologic toxicities-leukopenia and thrombocytopenia were observed but were reversible. In conclusion, combination chemotherapy with carboplatin and 5-FU was effective for locally advanced head and neck cancer in neoadjuvant setting, but it had limited benefits for recurrent diseases. Toxicities were tolerable and neurotoxicity, ototoxicity, and nephrotoxicity were not observed.
