The Society of Surgical Oncology (SSO) and its official journal, Annals of Surgical Oncology, have had a very important and successful partnership with the Japanese Society of Gastroenterological Surgery (JSGS). As recent President of the SSO and now Editor‐in‐Chief of Annals of Surgical Oncology, I would like to express our appreciation and gratitude for this longstanding relationship. This partnership has advanced our missions of promoting high‐quality surgical science focused on improving patient outcomes.
Annals of Surgical Oncology is a global journal. It has a worldwide readership and an international Editorial Board. It receives articles from all over the world. More than 10 000 institutions around the globe have access to Annals of Surgical Oncology. We expect that we will exceed 1 million article downloads this year, which reaches an enormous number of readers around the globe.
We celebrated the 25th anniversary of Annals of Surgical Oncology at the 2018 SSO Annual Meeting. Success of the Journal can largely be credited to the efforts of Dr Charles Balch. Dr Balch was the founding Editor‐in‐Chief and served for 25 years. He has often been a visiting professor to Japan, and has attended the JSGS meeting many times. The most prestigious award bestowed by the SSO is the Distinguished Service Award; Dr Balch is a former recipient. In 2018, the SSO renamed this award the Charles Balch Distinguished Service Award in recognition of Dr Balch's many contributions to make the SSO a global society and Annals of Surgical Oncology a global journal.
Article downloads from Annals of Surgical Oncology have steadily increased from 161 000 in 2007 to nearly 1 million article downloads in 2017 (Figure 1). The number of downloads and worldwide access to the Journal truly reflects its international prominence. Although 34% of the downloads were from North America, 32% were from the Asia‐Pacific region, 24% were from Europe, and 10% were from the rest of the world (Figure 2). It is important to note that of all the surgical journals in the world, Annals of Surgical Oncology has more published articles, more published pages, and more downloads than any other surgery journal.

Annals of Surgical Oncology has global engagement in all areas, including readership, article submissions, and Editorial Board membership. We have had well over 2000 reviewers in the past decade who have participated in improving the scientific quality of the journal—many from Japan. Japanese members serve on the Editorial Board for several sections of Annals of Surgical Oncology, including breast oncology, colorectal cancer, gastrointestinal cancer, hepatobiliary tumors, thoracic oncology, and translational research and biomarkers.
Many of our best articles come from Japan. There has been a strong track record of submissions from authors in Japan—especially from the JSGS (Figure 3). In past years, Annals of Surgical Oncology published a supplement specifically devoted to the best articles from the JSGS meeting. The SSO and Annals of Surgical Oncology are very proud of this relationship.

Japanese surgeons, and JSGS members in particular, have a very strong record of manuscript acceptances. In 2017, 18% of the articles accepted in Annals of Surgical Oncology came from Japan and 39% came from the USA (Figure 4). This number is growing and we anticipate it will continue to improve as our partnership continues.

Japan has the second highest rate of manuscript acceptances to Annals of Surgical Oncology of all countries in the world
Of the Japanese articles published in Annals of Surgical Oncology, 81% are cited. In fact, they are well cited. The impact factor of articles published by Japanese authors has somewhat exceeded the average from the rest of the world. Another indicator of impact for groups of articles is the Category Normalized Citation Impact (CNCI). This rating is normalized for subject focus, age, and document type. A CNCI value of 1 represents performance on par with the world average, values above 1 are considered above average and values below 1 are considered below average. Figure 5 shows that articles authored by Japanese experts and published in Annals of Surgical Oncology have a higher CNCI than those Japanese authors’ articles published in all other surgical journals. When you publish in Annals of Surgical Oncology, more people have access to your articles, and more people will download, read, and cite your articles.

The most cited articles from JSGS were by Beppu et al1, Yamada et al2, Arita et al3, Terashima et al4, Kobayashi et al5, and Koyama et al.6 In fact, the most cited article for the entire journal—not just Japanese publications but for all of Annals of Surgical Oncology for 2016—was an article that we celebrated at the 2018 Annual Meeting of the SSO entitled: “Prognostic Significance of Neutrophil‐to‐Lymphocyte Ratio and Platelet‐to‐Lymphocyte Ratio in Oncologic Outcomes of Esophageal Cancer: A Systematic Review and Meta‐analysis” by Yodying et al.7 There were 41 citations and 1300 downloads of this article.
The most prolific author in Annals of Surgical Oncology is Professor Masaki Mori, who has also served on the Executive Council of SSO (Figure 6). He has 76 publications which have been cited 1128 times. We thank Professor Mori for his many contributions to the Journal and to the SSO.

The SSO strives to be the premier organization for surgeons dedicated to the multidisciplinary care of cancer patients and advancing the science, education and practice of cancer surgery. We understand that, as cancer surgeons, despite all of the advances in chemotherapy, targeted therapy, immunotherapy, and radiation therapy, often the single best thing that we can do for our cancer patients is to carry out a good cancer operation. We have learned to carry out cancer surgery more safely, less invasively, and with less morbidity. Yet, we know that surgery alone will not cure many of our patients because their disease has already progressed beyond what we can resect. That is why it is so important that we engage not only in research about surgical techniques, but we must also be involved in basic and translational research and development of adjuvant therapies, especially new targeted therapies and immunotherapies. This is what will allow us to improve patient outcomes and cure more patients in the future. The JSGS has been an important partner in advancing this research mission.
We believe that the SSO truly is a global society and we are very interested in increasing our global outreach. The SSO now has over 575 international members across all categories. There are many active members from Japan and this number is growing, as we attract more and more members from around the world to join the SSO and attend the Annual Meeting.
The SSO now has a new learning management system, ExpertEd@SSO, an online system that is going to continue to allow delivery of educational content to members around the world. Even if members are unable to attend the annual SSO meeting, this is a benefit of membership that is very important, as many people now learn on their phones and computers. A host of new educational offerings is constantly under development.
Recently, Dr Chandra Are established the Global Forum of Cancer Surgeons at the annual SSO meeting. The SSO plans to continue this as a major initiative to address global problems in cancer surgery, including educational concerns. Professors Mori and Eguchi were co‐authors who have contributed to this effort.8
At the last SSO meeting, 20 different countries were represented on the podium. SSO also offers global partner poster sessions, where partner societies are invited to present their top abstracts from their respective surgical oncology meetings at the SSO Annual Cancer Symposium. JSGS participated in 2017 and 2018. The SSO/JSGS Joint Symposium in 2017 on intraductal papillary mucinous neoplasms of the pancreas was also very successful.
The SSO and JSGS have also partnered in many career development activities, including the international career development exchange, which began in 2014. Several attendees from Japan have participated and this has been a very successful program. SSO members have also participated in observerships offered by JSGS. SSO members greatly value this opportunity.
In summary, Annals of Surgical Oncology is the most cited surgical journal in the world. We certainly want to encourage manuscript submissions from all of our global partners and especially from the JSGS. The Journal now offers simultaneous publication at the time of the SSO Annual Meeting for all of the top‐ranked papers. Papers from our partners at JSGS are always among the top‐tier submissions, so we continue to encourage your participation in the SSO program.
SSO will continue to lead the global dialogue for surgical oncology and promote the value of cancer surgeons. Many educational resources are available to SSO members. In addition to access to Annals of Surgical Oncology, there are many other educational offerings, including the SSO virtual meeting, webinars, and other materials available at ExpertEd@SSO. Many articles published in Annals of Surgical Oncology are published as open access articles and are freely available.
On behalf of the SSO and Annals of Surgical Oncology, thank you for the tremendous friendship and partnership between our organizations. We hope that this will only continue to grow stronger in the years ahead.
