• Metastasis and tumor spread emerged as a central theme, guiding how researchers traced dissemination across sites and tracked tumor cell fate—from rectal carcinoma spread [5], to the broader spread of tumours in the body [14], to rectal cancer spread patterns [17], and to intravenously injected tumor cell fate studies [19], with biomarkers signaling metastatic progression [7].

• Histogenetic classification and prognosis framed tumor taxonomy as a core research approach, exemplified by glioma-group classifications linked to prognosis [2], an alternate glioma classification with prognosis commentary [3], classification of renal tumors [11], and prognosis-oriented grading in colon/rectum cancers [10].

• Endocrine modulation and serum biomarkers illuminate cancer progression, with studies on prostatic cancer hormone effects [9], acid phosphatase as a serum marker in metastatic prostate cancer [7], and the impact of thyroidectomy on metastatic thyroid cancer behavior [20].

• Diagnostic pathology and rapid diagnostic methods dominated methodological development, including rapid microscopical tumor diagnosis [13], comprehensive pathology of tumours [4], and histopathology-focused primary lung cancer study [6].
