(5) The agenda was adopted, and chairpersons and reporters were elected. (See Annex 1)
Session 1: Phase II Study of Concurrent Chemoradiotherapy and Extended-Field Radiotherapy for Locally Advanced Cervical Cancer (CERVIX-IV)
(6) Dr. Masaru Wakatsuki, Medical Doctor of Research Center Hospital for Charged Particle Therapy, National Institute of Radiological Sciences (NIRS) introduced the protocol of Cervix IV. The summary of the follow-up data was also presented by him. 87 cases were registered in this protocol. The follow-up rate at the point of this workshop was 99% (86/87cases).
Update of clinical data of Phase II Study of Concurrent Chemoradiotherapy and Extended-Field Radiotherapy for Locally Advanced Cervical Cancer (CERVIX-IV) was presented by representatives of each participating country with the following number of patients: Bangladesh (24), China (7), Indonesia (6), Japan (19), Korea (7), Malaysia (5), Philippines (4) Thailand (4) and Viet Nam (8)
Dr. Wakatsuki presented the summary of the clinical data. There are 87 patients registered this protocol and 83 patients were evaluated. Clinical results showed comparable toxicity between CERVIX-III and IV, therefore, the treatment protocol of CERVIX IV is acceptable. Loco-regional control is 95.5% at 2 years and 89.3% at 5 years. The overall survival is 89.6% at 2 years and 71.6% at 5 years, which is better than CERVIX- III
(7) An open discussion on the clinical data of Cervix-IV followed. For CERVIX-IV there is a need to collect additional data to complete the study and for publication in the coming years.
Session 2: New Protocols for Cervical Cancers (CERVIX-V)
(8)Following the discussion and agreement at the last workshop, two new protocols were introduced and discussed.
(9) First, Prof. Shingo Kato, Professor of the Department of Radiation Oncology, International Medical Center, Saitama Medical University introduced and reviewed "3D image-guided brachytherapy (3D-IGBT)". Next, Dr. Masaru Wakatsuki presented a preliminary report. In the report, he proposed 3 model cases of cervical cancers and also the treatment regimens using 3D-IGBT for each case with good representation in the variation of tumor size and parametrial invasion.
(10) Dr. Masaru Wakatsuki presented another protocol namely Phase II study of CCRT for locally advanced adenocarcinoma.- With increasing incidence of this histology type of cancer, he proposed data collection for a retrospective study on the above.
(11) An open discussion on the two new protocols followed.
For the 3D brachytherapy protocol, both technical feasibilities (infrastructure) and enrollment possibilities (resources of staff, machine and time) were discussed. The data center will send three simulated cases to the participants.
For second protocol of adenocarcinoma of cervical cancer, 60 patients are required. All participants are expected to send the number of adenocarcinoma or adenosquamous carcinoma cases in the last two years to data center. The full protocol will be presented next year by Dr. Wakatsuki. In the meantime, data center will send the form for retrospective study.
Session 3: Phase II Study of Chemoradiotherapy for NPC (T3-4, N0-1) (NPC-II)
(12) Prof. Tatsuya Ohno, Professor & Medical Director, Heavy Ion Medical Center, Gunma University introduced the protocol NPC-II.

The following numbers were reported: Bangladesh ( 0 ), China( 0 ), Indonesia ( 13 ), Japan( 0 ), Kazakhstan (0), Korea ( 0 ), Malaysia ( 6 ), Mongolia (0), Philippines( 0 ), Thailand ( 1 ), and Vietnam ( 50 ). Prof. Tatsuya Ohno presented the summary of the clinical data of ( 70 ) cases.
(13) An open discussion on the clinical data of NPC (T3-4, N0-1) (NPC-II) followed. The main discussion was about closing the study as the enrollment of new patients for NPC-II was poor over past 3 years. The participants explained their recruitment difficulties. Dr. Ohno mentioned the data of 70 patients can be published in international journal and it was agreed by the participants to close the NPC -II study.
Session 4: QA/QC of External Beam Therapy
(14) Report on a summary of intercomparison measurements using validated glass dosimeters done on 44 beams in 16 facilities with 4-18 MV at 11 countries were presented by Dr. Shigekazu Fukuda, Head of Heavy Particle Faculty Section, Dept. of Accelerator and Medical Physics, Research Center for Charged Particle Therapy, NIRS. This fiscal year, measurements were done in Kazakh Institute of Oncology and Radiology, Kazakhstan. Future plan is to do additional audit from host institutions in participating countries.
(15) Dr. Sang Hyoun Choi, Medical Physicist and Senior Researcher, Department of Radiation Oncology, Research Center for Radiotherapy, and Korea Heavy Ion Medical Accelerator Project in the Korea Institute of Radiological and Medical Sciences (KIRAMS), spoke on QA/QC for External Beam Radiotherapy and Current Status in Korea.
Session 5: Phase II Study of Concurrent Chemoradiotherapy (CCRT) for NPC (NPC-III)
(16) Prof. Tatsuya Ohno introduced the protocol NPC-III. The recent clinical data of Phase II Study of CCRT for NPC (NPC-III) was presented by representatives of each participating country. The following numbers were reported: Bangladesh (1), China ( 5 ), Indonesia ( 7 ), Japan (0), Kazakhstan (0), Korea (0), Malaysia (9 ), Mongolia (0), Philippines ( 7), Thailand (0) and Vietnam (20). Prof. Tatsuya Ohno presented the summary of the clinical data and the evaluation of the NPC-III study results. 47 patients of NPC-III were analyzed. The toxicities for NPC-III were tolerable when compared with NPC-I. The 2-year and 3-year local control rates for NPC-III was lower than NPC-I. The 2 year and 3 year PFS and OS were similar for NPC I and NPC III.
(17) An open discussion on the clinical data of Phase II study of CCRT for NPC-III followed. The issue of local control due to treatment interruption was discussed. It was also proposed that toxicities between the two studies should be evaluated. In addition, Prof. Ohno proposed that those who are using IMRT can implement this technique for NPC-III patients. Finally, the expected total number of patients for this study is 120.
