Treating Triple-Negative Breast Cancer: Recent Progress and What’s to Come Several sessions at SABCS highlighted our gains against this aggressive form of breast cancer—and the challenges that still remain By BCRF | January 20, 2021 BCRF. Ninety-five percent of newly diagnosed TNBC patients have early-stage disease, and based on recent clinical trial results, their five-year disease-free survival is well over 80 percent.
Treatment of Triple-negative Breast Cancer (cancer.org) chemotherapy (chemo) is the main systemic treatment option. And although TNBC tends to respond well to initial chemo, it tends to come back (recur) more frequently than other breast cancers.
IMpassion031 is a phase III trial in patients with early-stage TNBC testing the safety and effectiveness of the checkpoint inhibitor atezolizumab used in tandem with standard chemotherapy prior to surgery (called neoadjuvant therapy). ‥ IMpassion031 involved 333 newly diagnosed patients with TNBC who were randomly assigned to receive either atezolizumab plus chemotherapy (nab-paclitaxel, doxorubicin, or cyclophosphamide) or the same chemotherapy agents plus a placebo prior to undergoing breast cancer surgery.

Immunotherapy in Triple-Negative Breast Cancer: How to Move Forward October 1, 2020 Carlos H. dos Anjos, MD, and Romualdo Barroso-Sousa, MD, PhD ASCO Daily News. Immune checkpoint blockade (ICB) has revolutionized the treatment of early and advanced solid tumors, including triple-negative breast cancer (TNBC), especially when combined with cytotoxic chemotherapy. Only a fraction of patients with TNBC benefit from ICB plus cytotoxic chemotherapy, so biomarkers to predict a response are urgently needed, with emphasis on composite biomarkers.

Over the past 10 years, the number of PubMed-indexed papers published each year in PMC-OAS has grown, with the most recent years showing an exponential growth (Fig. 7).(Journal of Biomedical Semantics volume 6, Article number: 38 (2015))
上の論文数の推移をみると、確かに3倍くらいは軽く増えていました。別の文献を見ると、論文出版数の増加を言う際にWeb of Scienceなどを引用するのは間違いである。なぜなら毎年3%くらい収載する雑誌の数が増えているからと指摘しています。収載する雑誌が増えても、過去にさかのぼって論文を検索してくれるのであれば問題ないのではないでしょうか。
It’s clearly wrong to cite the growth of academic databases, such as Thomson Reuters Web of Science, which has increased its coverage by around 3% per year (barring occasions when the database incorporates a flood of new journals). That dramatically undercounts the true expansion: no database captures everything.
The increase in the number of searches was accompanied by a continuous increase in the number of records (i.e. the articles, abstracts and books included in the database) added in PubMed, as did those of other databases (Larsen & von Ins, 2010). A more dramatic increase in their numbers has occurred since 2004, when the number of records was approximately 15 million. By the first half of 2014 approximately 9.9 millionmore records have been added in Pubmed (a 66% increase from 2004), as evident from PubMed identification number (PMID) (http://www.nlm.nih.gov/bsd/licensee/baselinestats.html). This increase could be attributed to the increase in the number of researchers or an increase in their productivity. An analysis of several databases showed that despite the increase in literature, the productivity of scientists decreased, as shown by the number of papers per unique author (Larsen & von Ins, 2010). An analysis of PubMed records for the period 1978–2001 concluded that the growth of medical literature should be attributed to clinical research, while a shift away
from basic science was observed (Druss & Marcus, 2005). Simultaneously, an increase in new journal titles (the term used in PubMed for journals) was observed (3173 more titles in 2013 – new or due to title changes – compared to 2003)
(http://www.nlm.nih.gov/bsd/licensee/baselinestats.html), which might denote an increased demand for articles or a limited space in the available journals for the generated research.

とのこと。データはWeb of Scienceで、ここではreprint Author(コレスポンディングオーサー)論文に限定しているので、条件が異なるのですが、それにしても大きな食い違いです。
PubMEDとWeb of Scienceとの食い違い
PubMEDとWeb of Scienceとでは収載している雑誌が多少異なるはずですが、それとは別に、検索条件でどんな文書を含めたかでも結果が変わってきます。文書の種類を何も限定せずにPubMED検索してしまうと、RetractionのNoticeや、ただの短いCommentなども拾ってしまうようです。PubMEDとWeb of Scienceとで条件を揃えて検索することがそもそもかなり難しいようですね。
近年爆発的に増加しているオープンアクセスジャーナルをどれくらい収載しているかの差かもしれないと思って、MDPI社の発行するジャーナルの数を調べてみました。MDPIの説明によれば、全部で304個のジャーナルを発行しているそうです。そのうちPUBMEDに収載されているのが76個。Web of Science収録が161個です。ですから、PUBMED検索結果のほうが多いことは、これでは説明がつきません。
